Description

Technical Field

[0001] The utility model relates to a connection structure of a cargo box door, in particular to a novel limiting belt installation structure of the cargo box door. Background Art

[0002] In the prior art, the connection structure between the cargo box and the cargo box door is as follows: Figure 1 As shown, the left and right ends of the cargo box 1 and the cargo box door 2 are generally connected by a limiting chain 3. The connection through the limiting material strip 3 has the advantage of being easy to operate, but the connection through the limiting material strip 3 also has the following defects: (1) During braking or acceleration, the limiting chain may collide with the cargo box or the cargo box door due to inertia, which is likely to generate a lot of noise and may cause damage to the cargo box or the cargo box door; (2) The limiting chain is heavy, occupies a large space, and has an unsightly appearance. Utility Model Content

[0003] In response to the shortcomings of the existing technology, the utility model proposes a new limiting belt installation structure for the cargo box door, which connects the cargo box and the cargo box door through an elastic limiting belt, avoiding collisions caused by inertia like traditional limiting chains, and will not bump or generate noise.

[0004] In order to implement the above technical solution, the utility model provides a new type of limiting belt installation structure for the cargo box door, including: a cargo box and a cargo box door, the left and right end edges of the cargo box and the cargo box door are connected by an elastic limiting belt, the elastic limiting belt includes a steel belt, one end of the steel belt is provided with a bottom hook, and the other end of the steel belt is provided with a top limiting spring, and the top limiting spring and the steel belt are connected by a strong spring.

[0005] In the above technical solution, because the steel wire belt is strong and bendable, it can effectively close or open the cargo box door without adversely affecting the cargo box's appearance, making it very practical. Furthermore, by providing a strong spring, the elastic limit belt has a certain elastic expansion space to adapt to different usage scenarios. Furthermore, the elastic limit belt is lighter than traditional limit chains, avoiding the collisions caused by inertia and the noise caused by traditional limit chains.

[0006] Preferably, the top limiting spring piece is locked to the connecting lug provided on the cargo box by means of bolts, and the bottom hook is fastened to the end edge of the cargo box door by means of bolts, and can be easily installed or disassembled, which is simple and reliable. When a new elastic limiting belt needs to be replaced, the top limiting spring piece can be slightly bent outwards by using fingernails (or simple tools such as screwdrivers), and the large hole in the 8-shaped hole at one end of the limit can be easily taken out through the step bolt.

[0007] The beneficial effects of the novel cargo box door limiter strap mounting structure provided by the present invention are as follows: the novel cargo box door limiter strap mounting structure is rationally designed and easy to install and remove. The structural design of the elastic limiter strap, due to the good strength and bendability of the steel wire, allows the cargo box door to be closed or opened effectively without adversely affecting the appearance of the cargo box, making the process very practical. Furthermore, by providing a strong spring, the elastic limiter strap has a certain elastic expansion space to adapt to different usage scenarios. Furthermore, the elastic limiter strap is lighter than traditional limiter chains, can avoid collisions caused by inertia like traditional limiter chains, and will not bump or generate noise.

[0012] The following is a clear and complete description of the technical solutions in the embodiments of the present invention, in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary persons in this field without creative work are within the scope of protection of the present invention.

[0013] Embodiment: A novel limiting belt installation structure for a cargo box door.

[0014] Reference Figures 1 to 3As shown, a new type of limiting belt installation structure for a cargo box door includes: a cargo box 1 and a cargo box door 2, the left and right end edges of the cargo box 1 and the cargo box door 2 are connected by an elastic limiting belt 4, the elastic limiting belt 4 includes a steel belt 41, the strong steel belt 41 has good strength and bendability, one end of the steel belt 41 is provided with a bottom hook 44, the bottom hook 44 is fastened to the end edge of the cargo box door 2 by bolts, the other end of the steel belt 41 is provided with a top limiting spring 43, the top limiting spring 43 is locked to the connecting support ear provided on the cargo box 1 by bolts, the top limiting spring 43 is connected to the steel belt 41 by a strong spring 42, so that the elastic limiting belt 4 has a certain elastic expansion and contraction space to adapt to different usage scenarios.

[0015] The limiting belt installation structure of the present novel cargo box door is rationally designed and easy to install and disassemble. Through the structural design of the elastic limiting belt 4, since the steel wire 41 has good strength and is bendable, the cargo box door 2 can be closed or opened well without adversely affecting the appearance of the cargo box 1 during the process, which is very practical. Moreover, by providing a strong spring 42, the elastic limiting belt 4 has a certain elastic expansion space to adapt to different usage scenarios. Moreover, the elastic limiting belt 4 is lighter than the traditional limiting chain 3, and can avoid collisions caused by inertia like the traditional limiting chain 3, without bumping or generating noise. The elastic limiting belt 4 can be easily installed or disassembled with the step bolt, which is simple and reliable. When a new elastic limiting belt 4 needs to be replaced, just use your fingernails (or simple tools such as screwdrivers) to slightly bend the top limiting spring piece 43 outwards, and the large hole in the 8-shaped hole at one end of the limit can be easily removed through the step bolt.

[0016] The above description is only a preferred embodiment of the present invention, but the present invention should not be limited to the contents disclosed in the embodiment and the drawings. Therefore, any equivalent or modification completed without departing from the spirit disclosed in the present invention shall fall within the scope of protection of the present invention.
