Description

Pretensioning belt in a bundler

technical field

The invention belongs to the technical field of binding tools, and relates to a pretensioning belt, in particular to a pretensioning belt in a binding device.

Background technique

When the vehicle is loaded with goods, a binding device is required to bind the goods to ensure that the goods will not move or fall from the original position during transportation.

The ratchet type binding device includes a ratchet, a handle, a rotating shaft, a gear plate and a bracket, etc. One end of the strap is tied to the bracket, and the other end is tied to the shaft. The handle drives the shaft to rotate to tighten the strap, and the ratchet and the gear plate The fit prevents the shaft from reversing.

Chinese Utility Model Patent [Application No.: 200920186299.9, Publication No.: CN201506291U] discloses a binding device, which includes a body assembly, a handle, a handle and a rotating shaft. The handle and the body assembly are hinged through a rotating shaft. The above-mentioned handle is slidably connected with a handle, and the end of the handle can be embedded between the ratchet teeth of the ratchet wheel. The binder also includes a lock, which can prevent the handle from sliding when the lock is locked. It adopts a lock fixed on the handle or handle, and when the lock is locked, the lock can prevent the handle from moving. When the gear plate is embedded between the ratchets of the ratchet, it is not fixed by direct contact. Instead, it will slide against the ratchets for a short period of time before fully abutting against the ratchets, so that the ratchet is reversed until the ratchets are completely against the gear plate. Abutment, due to insufficient or low pre-tightening force of the binding belt, the reversal of this small section of the ratchet causes the binding belt to fail to reach the desired pre-tightening force when the original ratchet stops forward rotation.

That is to say, the outer belt is composed of two layers of outer belt bodies. In order to ensure the firmness of the connection of the outer belt body, the two ends of the outer belt body are overlapped for a part and then sewed together with the suture part of the belt body. The length is quite, like this, also can make this pretensioning belt comparatively attractive in appearance.

In the above-mentioned pretensioning belt in the binder, the inner belt is located between the two sides of the outer belt body. When the pre-tightening belt is stretched, the outer belt bodies located on both sides of the inner belt limit the degree of stretching, so as to avoid excessive stretching of the pre-tightening belt and damage the elasticity of the inner belt. At the same time, the outer belt body is arranged on both sides of the inner belt to avoid cutting the inner belt, thereby ensuring the function of the pre-tightening belt and improving its stability during use.

In the above-mentioned pretensioning belt in the binder, an annular connecting portion is formed between the end of the outer belt and the sewing portion. The two ends of the outer band are the bends of the outer band body. A ring-shaped connecting portion is provided so that the pretensioning belt can be more conveniently connected to a hook or a binding device. When in use, the hook passes through the connecting portion, so that the connection between the hook and the belt body is relatively stable.

detailed description

As shown in Fig. 1 , Fig. 2 and Fig. 5 , the pretensioning band in the binder includes a strip-shaped and flat strip body 1, and the strip body 1 includes an outer band 1a and an elastic inner band 1b. The lengths of the outer belt 1a and the inner belt 1b are both equivalent to the length of the belt body 1 . Wherein, the outer belt 1a is a nylon ribbon or a polypropylene ribbon. Select nylon webbing or polypropylene fiber belt as the concrete material of outer belt 1a, make the intensity of outer belt 1a stronger, pulling force is bigger, be difficult to be torn off. The material of the inner band 1b is rubber or the inner band 1b is a spandex band, and the rubber or spandex band is selected as the concrete material of the inner band 1b, so that the elasticity of the inner band 1b is better, and the pre-tightening effect of the pre-tensioning band is improved.

The side of the inner belt 1b is close to the side of the outer belt 1a, and there are two seams 1c between the two, which firmly connect the inner belt 1b and the outer belt 1a, and the two seams 1c are along the length of the belt body 1 Direction distribution, the length of the inner belt 1b located between the two seamed parts 1c is smaller than the length of the outer belt 1a located between the two seamed parts 1c.

The pulling force of the outer belt 1a is large enough to ensure that the belt body 1 has sufficient pulling force. The length of the inner bag between the two seams 1c is smaller than the length of the outer belt 1a between the two seams 1c means that when the inner belt 1b is not stretched, the length of the inner belt 1b is between the two seams 1c. Less than the length of the outer band 1a. When the belt body 1 is initially straightened and stretched without deforming the inner belt 1b, the length of the outer belt 1a is greater than the length of the inner belt 1b; continue to pull the two ends of the belt body 1, because the inner belt 1b has elasticity, the inner belt 1b is pulled Elongated. Thereafter, the inner band 1b is in a stretched state, and because the inner band 1b has elasticity, the inner band 1b has a tendency to retract, and the inner band 1b makes the two seams 1c tend to approach each other, so that the two ends of the band body 1 have a close trend. The belt body 1 has a pre-tightening force. Continue to pull the belt body 1 until the outer belt 1a is straightened, as shown in Figure 5, due to the restriction of the outer belt 1a, the inner belt 1b is no longer stretched. In this way, the elasticity of the inner belt 1b is not damaged due to excessive stretching, and the belt body 1 has sufficient tension.

As shown in Figure 3, the outer belt 1a includes a strip-shaped outer belt body 1a1. After the outer belt body 1a1 is bent along its middle, its two ends are fixedly connected to form the outer belt 1a. The two seamed parts 1c are respectively close to the outer belt. At both ends of the belt 1a, one end of the inner belt 1b is fixedly connected to one of the seaming parts 1c, and the other end of the inner belt 1b is fixedly connected to the other seaming part 1c. That is, the outer tape 1a is composed of two outer tape bodies 1a1. In order to ensure the firmness of the connection of the outer belt body 1a1, the two ends of the outer belt body 1a1 are overlapped for a part and then sewn together with the suture portion 1c of the belt body 1, the length of the overlapping length of the two ends of the outer belt body 1a1 It is equivalent to the length of the seam portion 1c of the belt body 1, so that the pretensioning belt can also be made more beautiful.

The inner belt 1b is located between the two sides of the outer belt body 1a1. That is to say, the outer belt body 1a1 wraps the inner belt 1b inside the outer belt body 1a1. When the pre-tightening belt is stretched, the outer belt bodies 1a1 located on both sides of the inner belt 1b limit the degree of stretching, so as to avoid excessive stretching of the pre-tensioning belt and damage the elasticity of the inner belt 1b. At the same time, the outer belt body 1a1 is arranged on both sides of the inner belt 1b to avoid cutting the inner belt 1b, ensuring the function of the pretension belt and improving its stability during use.

An annular connecting portion 1a2 is formed between the end portion of the outer band 1a and the sewn portion 1c. The two ends of the outer belt 1a are the bends of the outer belt body 1a1. The ring-shaped connecting portion 1a2 is provided so that the pretensioning belt can be more conveniently connected to the hook 3 or the binding device 2 . When in use, the hook 3 passes through the connecting portion 1a2, so that the connection between the hook 3 and the belt body 1 is relatively stable.

As shown in Figure 4, the inner belt 1b includes a strip-shaped inner belt body 1b1. The bend of 1b1 forms an annular inner connecting portion 1b2, and the inner connecting portion 1b2 is located inside the connecting portion 1a2. The inner connecting part 1b2 bears against the inner side of the connecting part 1a2. Both ends of the inner belt body 1b1 are evenly bent towards the middle of the inner belt body 1b1, the bent length is relatively short, and the two ends of the inner belt body 1b1 are not arranged alternately.

The joint between the end and the side of the inner belt body 1b1 is overlapped and sewn with the seamed portion 1c. Such an arrangement makes the connection between the inner belt body 1b1 and the outer belt body 1a1 relatively tight and firm, and the inner belt body 1b1 and the seaming portion 1c are sewn together, making the production of the pretensioning belt relatively simple.

As shown in FIG. 6 , when in use, one of the connecting parts 1 a 2 of the pre-tightening strap is sleeved on the hook 3 , and the other connecting portion 1 a 2 of the pre-tightening strap is sleeved on the connecting column 2 a of the binder 2 . When the binding device 2 wraps the binding band 4 to shorten the length of the binding band 4, the pretensioning belt is also subjected to the pulling force of the binding device 2, and the inner band 1b is stretched. After the binding device 2 stops winding, the strap 4 is in a tensioned state, and the pretensioning belt is also in a stretched state, and the pretensioning belt has a pretensioning force on the binding device 2 and the hook 3 . Due to the setting of the pre-tensioning belt, the binding device 2 can better bind the goods.
