Description

A durable retractable bed frame

technical field

The utility model relates to a bed frame, in particular to a durable telescopic bed frame.

Background technique

Nowadays, the pressure of population is increasing, the place where people live is getting smaller and smaller, and the living space is often insufficient. Therefore, there is an urgent need for a bed that can improve space utilization.

In the Chinese invention patent application CN102940418A, an automatic telescopic bed is recorded. The end and middle of the telescopic bed are supported by sliding panels. The upper parts of the two panels are connected to the head of the bed. The connecting device is retractable. The bed is equipped with a roll-up mat. The device, which passes through the middle vertical panel and connects with the vertical panel at the end of the bed, can play a fixed role. There is a fully automatic rolling device embedded in the inner panel at the end of the bed, which can make the bed stretch forward and backward. When the automatic retractable bed is not in use, it occupies very little space, and can be used as a chair and a sofa after shrinking.

However, the telescopic bed has a complex structure and the bed frame has low strength and poor durability.

Utility model content

In view of this, the utility model discloses a telescopic bed frame which has high strength and can bear relatively heavy weight.

The purpose of this utility model is achieved through the following technical solutions: a durable telescopic bed frame, including a first bed frame and a second bed frame arranged in sequence, characterized in that: the bottom of the first bed frame is provided with a first slide The two sides of the first chute are respectively provided with a first support block; the bottom of the second bed frame is provided with a second chute coaxial with the first chute, and the two sides of the second chute are respectively provided with a The second support block; also includes a connecting frame arranged between the first bed frame and the second bed frame; the top of the connecting frame is provided with a slide rail matched with the first chute and the second chute, so The slide rail is embedded in the first chute and the second chute; a plurality of sequentially hinged folding plates are arranged between the first bed frame and the second bed frame.

The first support block and the second support block respectively play a role in supporting the first bed frame and the second bed frame in the utility model, so that they can be stably placed on the ground. The first bed frame and the second bed frame can slide along the slide rails to adjust the distance between them, so as to realize the adjustment of the width or length of the bed frame, thereby improving the utilization rate of the interior space of the room. However, the first chute, the second chute and the sliding rail cooperate with each other, and the structure is simple, the failure rate is low, and the service life is long. And running through the first chute and the second chute is more conducive to enhancing the overall strength of the first bed frame and the second bed frame, so that the load-bearing performance is improved and it is not easy to be damaged. In particular, a plurality of sequentially hinged folding plates are arranged between the first bed frame and the second bed frame. Before the second bed frame, avoid the exposure of the connecting frame and keep the surface of the bed frame flat to improve the comfort of the product. The folding plate also has a position-limiting effect on the first bed frame and the second bed frame, so as to prevent the bed frame from being damaged due to overstretching. In addition, the folded panels that are not fully unfolded can also enhance the load-bearing performance of the connecting frame.

Further, one side of the slide rail is also provided with a horizontal connecting frame receiving groove, and the other side is provided with a third support block; the first bed frame and the second bed frame on the same side as the connecting frame containing groove A support block and a second support block are slidably embedded in the receiving groove of the connecting frame; the first support block and the second support block on the other side of the first bed frame and the second bed frame are respectively provided with a horizontal bed frame accommodating groove, and the third support block is slidably embedded in the receiving groove of the bed frame.

The connecting frame receiving groove can wrap the first support block and the second support block on one side, and limit the two, so as to avoid deviation between the first bed frame, the second bed frame and the connecting frame during the telescopic movement. Wear and tear due to movement, reducing the overall strength and service life of the bed frame. The third support block provided on the other side is wrapped by the bed frame receiving groove, which can further prevent the offset between the first bed frame, the second bed frame and the connecting frame. The utility model respectively adopts the receiving groove of the connecting frame and the receiving groove of the bed frame to fix the first bed frame, the second bed frame and the connecting frame from both sides. Carry out shaping and stabilization to avoid shaking of the bed frame due to deformation and wear after long-term use.

Further, the surface of the slide rail is respectively provided with a plurality of hemispherical concave surfaces, and balls are arranged in the hemispherical concave surfaces; the surface of the hemispherical concave surfaces is also provided with radial reinforcing grooves.

The use of balls can effectively reduce the friction coefficient between the slide rail and the chute, reduce the wear on the surfaces of the two, and prolong the service life of the utility model. On the one hand, the reinforcing groove can improve the strength of the hemispherical concave surface, preventing its deformation from affecting the smoothness of the stretching action of the bed frame; on the other hand, it can also reduce the wear of the balls.

Further, at least one reinforcement beam perpendicular to the slide rail is provided in the receiving groove of the connecting frame, and the top of the reinforcement beam abuts against the slide rail.

The reinforcing beam and the slide rail together form a three-dimensional reinforcing frame, which can further increase the strength of the bed frame and prevent the bed frame from being deformed by force.

Compared with the prior art, the utility model has the following beneficial effects:

1. The way that the first chute and the second chute cooperate with the slide rail of the utility model has simple structure, low failure rate and long service life. And running through the first chute and the second chute is more conducive to enhancing the overall strength of the first bed frame and the second bed frame, so that the load-bearing performance is improved and it is not easy to be damaged.

2. The utility model respectively adopts the connecting frame receiving groove and the bed frame receiving groove to fix the first bed frame, the second bed frame and the connecting frame from both sides. The frame is shaped and stabilized as a whole to avoid shaking of the bed frame due to deformation and wear after long-term use.
