DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-5 A safety-enhanced truck tail lift device comprises a truck body 1, a tail lift mechanism 2 is installed at the entrance of the truck body 1, and the tail lift mechanism 2 is controlled by a hydraulic device to lift and fold;

[0031] A foldable protection mechanism 3 is also installed on the tailgate mechanism 2, and the protection mechanism 3 protects both sides of the tailgate mechanism 2;

[0032] The tailgate mechanism 2 includes a lifting tailgate body 201, the bottom of which is connected to a hydraulic rod so that the lifting tailgate body 201 can be lifted and folded;

[0033] A connection groove 202 is symmetrically provided on the top of the lifting tail lift body 201, and a side baffle 203 is fixedly connected to the outside of the connection groove 202. The side baffle 203 limits the maximum deployment angle of the protection mechanism 3 and makes the protection mechanism 3 slightly tilted to prevent the protection mechanism 3 from being too vertical and rotating inward to cause tipping. A storage groove 204 is provided on the top of the lifting tail lift body 201, and the storage groove 204 is connected with the connection groove 202;

[0034] The protection mechanism 3 includes a connecting shaft 301 , which is hinged inside the connecting groove 202 . A protection fence 302 is fixedly connected to the connecting shaft 301 , and the protection fence 302 can be received inside the receiving groove 204 .

[0035] Through the above technical solution, connecting grooves 202 are provided on both sides of the top of the lifting tail lift body 201, and the connecting shaft 301 is hingedly connected through the connecting grooves 202, so that the guardrail 302 fixedly connected to the connecting shaft 301 can be unfolded to form a guardrail to prevent people and goods from falling from the side of the lifting tail lift body 201. At the same time, a storage groove 204 is provided on the top of the lifting tail lift body 201. When the guardrail 302 is stored, it is located inside the storage groove 204, thereby achieving the effect of improving the protection performance and facilitating the storage of the tail lift;

[0036] How the tailgate body 201 is connected to the truck body 1 and how the hydraulic control device controls the lifting and folding of the tailgate body 201 are both prior arts and are not improvement plans of the present application. Therefore, they will not be described in detail in the application documents.

[0037] Specifically, auxiliary grooves 205 are provided between the storage grooves 204 , and the auxiliary grooves 205 penetrate the storage grooves 204 on both sides.

[0038] Through the above technical solution, the auxiliary groove 205 is used to facilitate the unfolding of the guardrail 302. When the diameter of the guardrail 302 matches the diameter of the storage groove 204, it is difficult to unfold the guardrail 302 with fingers if the auxiliary groove 205 is not provided.

[0039] Specifically, a cross bar is disposed in the middle of the guardrail 302 , and grooves for receiving the cross bar are provided between the receiving slots 204 .

[0040] Through the above technical solution, the purpose of setting a cross bar between the guardrails 302 is to further enhance the protective performance of the guardrails 302, so that when loading and unloading goods, the porters can use the guardrails 302 as handrails, and when pushing and pulling goods, the guardrails 302 can also be used as side barriers to ensure safety.

[0041] Specifically, the shape of the storage groove 204 is the same as that of the guardrail 302 , and the diameter of the storage groove 204 is equal to the diameter of the guardrail 302 .

[0042] Through the above technical solution, the storage slot 204 and the guardrail 302 are set to have the same shape, so that after the guardrail 302 is folded and stored, it can be completely limited by the storage slot 204 and will not shake due to excessive or excessive gap between the guardrail 302 and the storage slot 204.

[0043] Specifically, an auxiliary hanging hole 206 is opened on the side of the lifting tailgate body 201, and an auxiliary hook 303 is installed on the top of the guardrail 302. The auxiliary hook 303 connects the guardrail 302 and the auxiliary hanging hole 206 to fix the unfolding angle of the guardrail 302.

[0044] Through the above technical solution, the purpose of providing the auxiliary hanging hole 206 is to enable the bottom of the auxiliary hook 303 to penetrate, so as to achieve the connection between the guardrail 302 and the lifting tailgate plate 201 through the auxiliary hook 303, support the guardrail 302, and prevent the guardrail 302 from tipping over.

[0045] Specifically, the auxiliary hook 303 includes a vertical rod 3031, the upper end of the vertical rod 3031 is fixedly connected with a threaded head 3032, the threaded head 3032 is threadedly connected to the top of the guardrail 302, and the lower end of the vertical rod 3031 is installed with a rotatable threaded cap 3033, and the internal thread of the threaded cap 3033 is connected to the hook head 3034.

[0046] Through the above technical solution, the threaded head 3032 set at the top of the threaded head 3032 is used for threaded connection with the top of the guardrail 302, and the threaded cap 3033 set can change the connection depth of the hook hook head 3034 by rotating, thereby changing the tightness of the connection between the hook hook head 3034 and the auxiliary hanging hole 206. The use process is to first fix it to the top of the guardrail 302 through the threaded head 3032, then pass the hook hook head 3034 through the auxiliary hanging hole 206, and finally rotate the threaded cap 3033 to lock the connection between the hook hook head 3034 and the auxiliary hanging hole 206.

[0047] When in use, by providing connection grooves 202 on both sides of the top of the lifting tail lift body 201, and hingedly connecting the connecting shaft 301 through the connection grooves 202, the guardrail 302 fixedly connected to the connecting shaft 301 can be unfolded to form a guardrail to prevent people and goods from falling from the side of the lifting tail lift body 201. At the same time, a storage groove 204 is provided on the top of the lifting tail lift body 201. When the guardrail 302 is stored, it is located inside the storage groove 204, thereby achieving the effect of improving the protection performance and facilitating the storage of the tail lift.

[0048] By opening an auxiliary groove 205 on the side of the lifting tailgate body 201 and threading the auxiliary hook 303 on the top of the guardrail 302, the auxiliary hook 303 is installed after the guardrail 302 is unfolded to limit the unfolding angle of the guardrail 302, and the auxiliary hook 303 is removed when the guardrail 302 is stored, thereby further improving the safety protection effect.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
