Description

Trolley self-locking structure

Technical Field

The utility model relates to the technical field of trolleys, in particular to a trolley self-locking structure.

Background

A trolley is a hand tool for handling and transporting objects. It usually consists of a platform and four wheels, sometimes also equipped with handles or grips to facilitate pushing and handling.

The trolley is widely applied to various fields such as warehouse logistics, home relocation, market supermarkets, industrial production and the like. The device can help people to easily move heavy objects or large articles from one place to another, lighten the burden of a human body and improve the working efficiency. However, in the prior art, a person is required to fix the trolley, so that manpower is wasted, and the stability is poor because the trolley cannot be locked.

Disclosure of utility model

The utility model provides a trolley self-locking structure, which solves the technical problems.

The scheme for solving the technical problems is as follows:

The utility model provides a trolley auto-lock structure, includes fixing base, platform truck crossbeam, couple, push rod and spring beam, the fixed plate is installed to the below of fixing base, rotate on the fixed plate and install the couple, rotate on the fixing base and install the pivot, the below of pivot is equipped with the ejector pad, the below swing joint of couple has the push rod, the end-to-end connection of push rod has the spring beam, the platform truck crossbeam is located the platform truck, couple and mutual joint of platform truck crossbeam are fixed the platform truck.

On the basis of the technical scheme, the utility model can be improved as follows.

Further, one end of the rotating shaft is connected with a pedal.

The beneficial effects of adopting the further scheme are as follows: the user can conveniently rotate the rotating shaft by stepping on the pedal, so that the hook is separated from the trolley.

Further, two hooks are arranged in total, and the two hooks are symmetrically distributed below the fixing seat.

The beneficial effects of adopting the further scheme are as follows: the trolley cross beam is clamped through the two hooks, so that the trolley is more stable when fixed.

Further, the push block is in contact with the push rod.

The beneficial effects of adopting the further scheme are as follows: the push rod is pushed to move when the rotating shaft rotates conveniently.

The beneficial effects of the utility model are as follows: when the trolley is used, the trolley is pushed into the platform, the trolley beam impacts the hook, at the moment, the hook pushes the push rod to squeeze the spring, so that the hook is automatically clamped into the bottom of the trolley, then a user loads and unloads cargoes, when the trolley is required to be released, the user rotates the rotating shaft by stepping on the pedal, and the push rod is pushed to pull the hook through the push block when the rotating shaft rotates, so that the hook is separated from the trolley.

The foregoing description is only an overview of the present utility model, and is intended to provide a better understanding of the present utility model, as it is embodied in the following description, with reference to the preferred embodiments of the present utility model and the accompanying drawings.

Referring to fig. 1 to 2, an embodiment of the present utility model is as follows:

Example 1

The utility model provides a trolley self-locking structure, including fixing base 1, trolley crossbeam 4, couple 5, push rod 6 and spring bar 8, fixed plate 3 is installed to fixing base 1's below, rotate on the fixed plate 3 and install couple 5, couple 5 is equipped with two altogether, and two couples 5 are in fixing base 1's below symmetric distribution, when using, the trolley pushes into the platform position, trolley crossbeam 4 striking couple 5, at this moment, couple 5 promotes push rod 6 extrusion spring, make couple 5 automatic card go into the trolley bottom, afterwards the user carries out cargo handling, when needs release the trolley, the user rotates pivot 2 through trampling the footboard, push rod 6 pulling couple 5 through pusher 7 when pivot 2 rotates, and then make couple 5 break away from the trolley, install pivot 2 on the fixing base 1 rotation, pivot 2's one end is connected with the footboard, pivot 2's below is equipped with pusher 7, pusher 7 contacts with pusher 6, trolley crossbeam 4 is located the trolley, 5 and trolley crossbeam 4 is clamped each other and is fixed to trolley crossbeam 4.

A trolley self-locking structure based on embodiment 1, when in use: when the trolley is used, the trolley is pushed into the platform position, the trolley beam 4 impacts the hook 5, at the moment, the hook 5 pushes the push rod 6 to squeeze the spring, so that the hook 5 is automatically clamped into the bottom of the trolley, then a user loads and unloads cargoes, when the trolley is required to be released, the user rotates the rotating shaft 2 by stepping on the pedal, and when the rotating shaft 2 rotates, the push rod 6 is pushed by the push block 7 to pull the hook 5, so that the hook 5 is separated from the trolley.

The above description is only of the preferred embodiments of the present utility model, and is not intended to limit the present utility model in any way; those skilled in the art will readily appreciate that the present utility model may be implemented as shown in the drawings and described above; however, those skilled in the art will appreciate that many modifications, adaptations, and variations of the present utility model are possible in light of the above teachings without departing from the scope of the utility model; meanwhile, any equivalent changes, modifications and evolution of the above embodiments according to the essential technology of the present utility model still fall within the scope of the present utility model.
