Description

Handrail reinforced structure of handcart

Technical Field

The invention relates to a trolley, in particular to a handrail reinforcing structure of the trolley.

Background

The cart is a transport vehicle that is manually pushed and pulled, and although the cart material transport technology is continuously developed, the cart is still used as an indispensable transport tool. For the convenience of manpower push-and-pull, all can install the handrail on the handcart, the handrail is in folding the state of accomodating under the condition that the handcart does not use, the handrail carries on spacingly through the horizontal body of rod of elastic mounting under the user state, thereby be convenient for the application of force, however because some goods weight are too big, the horizontal body of rod of elastic mounting can receive very big pressure in the process, cause elastic construction to destroy easily under the long-term use, thereby lead to the unable folding accomodating of handrail, consequently need add an auxiliary reinforced structure on the handrail in order to reduce the load that the horizontal body of rod received.

Disclosure of Invention

In view of this, the invention provides a handrail reinforcing structure of a handcart, which enables a handrail to be more stably limited and to save more labor when pushing the handrail compared with the prior art in which a reinforcing mechanism is additionally arranged on the handrail of the handcart, and the reinforcing mechanism can stop the limiting effect by breaking a suction disc, so that the handrail can be folded and stored.

Therefore, the invention provides a handrail reinforcing structure of a handcart, which comprises a handcart body, wherein the handcart body comprises a base, casters, a connecting seat and a handrail, the casters are arranged on the lower surface of the base, the connecting seat is fixedly arranged on the upper surface of the base, the handrail is hinged on the connecting seat, the bottom end of the handrail is fixedly connected onto the base through a reinforcing mechanism, the reinforcing mechanism is positioned behind the handrail, the reinforcing mechanism comprises a connecting part and a sucker, the first end part of the connecting part is fixedly connected onto the bottom end of the handrail, the sucker is fixedly arranged on the second end part of the connecting part, and the sucker is adsorbed on the base.

Furthermore, the connecting part comprises a first rod body, a second rod body and a three-way pipe, and the first rod body and the second rod body are connected together through the three-way pipe.

Further, the first end of the first rod body is fixedly connected to the bottom end of the handrail, the second end of the first rod body is detachably connected to the first pipe orifice of the three-way pipe, the first end of the second rod body is detachably connected to the second pipe orifice of the three-way pipe, and the second end of the second rod body is fixedly provided with a sucker.

Further, the second end of the first rod body is in threaded connection with the first pipe orifice of the three-way pipe, and the first end of the second rod body is in threaded connection with the second pipe orifice of the three-way pipe.

Furthermore, the first rod body is an arc-shaped rod, and the second rod body is a straight rod.

Furthermore, the middle part of the handrail is sleeved with a reinforcing sleeve plate.

Furthermore, a reinforcing rib is arranged in the middle of the reinforcing sleeve plate.

Furthermore, the handrail is of a U-shaped structure, and the reinforcing sleeve plate is a waist-shaped sleeve plate.

Furthermore, the opposite ends of the reinforcing sleeve plate in the length direction are fixedly connected with the opposite ends of the handrail in the width direction respectively.

The invention provides a handrail reinforcing structure of a handcart, which mainly comprises a handcart body and a reinforcing mechanism, wherein the handcart body comprises a base, casters, a connecting seat and handrails, the casters are arranged on the lower surface of the base, the connecting seat is fixedly arranged on the upper surface of the base, the handrails are hinged on the connecting seat, the reinforcing mechanism is connected between the bottom of each handrail and the base, the reinforcing mechanism comprises a connecting part and a sucker, the connecting part comprises a first rod body, a second rod body and a three-way pipe, the first rod body and the second rod body are connected together through the three-way pipe, the first end part of the first rod body is fixedly connected to the bottom end of each handrail, the second end part of the first rod body is detachably connected to the first pipe orifice of the three-way pipe, the first end part of the second rod body is detachably connected.

The three-way pipe still has the third mouth of pipe simultaneously, only need when need not to use strengthening mechanism with the second body of rod from the second mouth of pipe take out and install on the third mouth of pipe can, thereby the sucking disc can't adsorb on the base and can't link together handrail and base this moment.

The strengthening mechanism that the handrail was add at the push-and-pull in-process and the horizontal body of rod that just exists originally all can bear the pressure that the push-and-pull brought, thereby strengthening mechanism only plays the load that the additional contribution alleviateed the horizontal body of rod, therefore the suction of sucking disc always satisfies joint strength's demand.

Therefore, compared with the prior art that the reinforcing mechanism is additionally arranged on the handrail of the trolley, the handrail is more stably limited, labor can be saved when the handrail is pushed, and meanwhile, the reinforcing mechanism can stop the limiting effect by disconnecting the sucking disc, so that the handrail can be folded and stored.
