The tarpaulin body of this utility model has good waterproof, wear-resistant, and corrosion-resistant properties, providing better protection for the cargo inside the truck and effectively reducing wear and tear on the tarpaulin body from the truck frame.

[0004] The tarpaulin is secured to the tarpaulin body by being hooked onto the first connecting ring via the first connecting fastener. However, the first connecting ring penetrates the tarpaulin body, so during use, rainwater from the environment will enter the inner side of the tarpaulin body through the first connecting ring, causing the covered goods to become damp and affecting the user experience of the device.

[0005] Therefore, in order to solve the above problems, a truck tarpaulin that is easy to tie and secure is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a truck tarpaulin that is easy to bind and fix, in order to solve the problem mentioned in the background art where the tarpaulin is fixed by hooking the first connecting fastener onto the first connecting ring, but the first connecting ring penetrates through the tarpaulin body. During use, rainwater in the environment will enter the inner side of the tarpaulin body through the first connecting ring, causing the covered goods to get damp, which will affect the user experience of the device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a truck tarpaulin that is easy to bind and fix, comprising: a tarpaulin body, wherein the bottom surface of the tarpaulin body is provided with a wear-resistant layer;

[0008] A fixing structure is installed on the bottom surface of the wear-resistant layer. The fixing structure includes a shell, which is sewn to the bottom surface of the wear-resistant layer. A sleeve is fixedly installed on the surface of the shell by threads. A rope drum and a worm gear are movably installed on the inner side of the shell through bearings. A binding rope is wound on the rope drum. A worm wheel is fixedly connected to one end of the rope drum. A motor is fixedly installed on the inner side of the shell.

[0009] Preferably, the fixing structure is provided in four sets, and the four sets of fixing structures are respectively located at the four corners of the bottom surface of the wear-resistant layer.

[0010] Preferably, the sleeve is trumpet-shaped, and the inner diameter of the small end of the sleeve is smaller than the diameter of the binding rope.

[0011] Preferably, the binding rope passes through the outer shell via a loop.

[0012] Preferably, the worm gear meshes with a worm wheel.

[0013] Preferably, the output end of the motor is fixedly connected to the worm gear.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by sewing the outer shell to the bottom surface of the wear-resistant layer, the fixing structure can be fixed to the bottom surface of the tarpaulin body without damaging the surface of the tarpaulin body. Moreover, when in use, the fixing structure is located on the inner side of the tarpaulin body, which can prevent the fixing structure from being eroded by rainwater and rusting, and can ensure the service life of the fixing structure.

[0015] This utility model features a fixing structure with a wear-resistant layer on the bottom surface of the tarpaulin body. The outer shell is sewn onto the bottom surface of the wear-resistant layer. When the tarpaulin body is used to cover goods on a truck, the wear-resistant layer is located inside the tarpaulin body, providing rain protection. The outer shell's location inside the tarpaulin body prevents internal components from being damaged by rain, extending the service life of the fixing structure. The fixing structure is relatively heavy, with four sets of fixing structures located at the four corners of the bottom surface of the wear-resistant layer. When covering goods, the four sets... The fixing structure can stretch and position the four corners of the tarpaulin body and the wear-resistant layer separately, preventing the covered tarpaulin body and wear-resistant layer from being blown away by the wind and causing inconvenience. Starting the motor can drive the worm gear to rotate. The worm gear meshes with the worm wheel. The rotation of the worm gear can drive the rope drum to rotate, realizing the winding or unwinding of the rope on the rope drum. When the rope gets wet by rain, the motor can drive the rope drum to retract the rope drum into the outer shell. The rope moves in the sleeve, which can wipe off the rainwater on the surface of the rope, preventing a large amount of rainwater from entering the outer shell and accelerating the damage to the fixing structure.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 One embodiment provided by this utility model:

[0023] The tarpaulin body 1 and motor 27 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0024] A truck tarpaulin that is easy to tie and secure includes: a tarpaulin body 1, and a wear-resistant layer 11 is provided on the bottom surface of the tarpaulin body 1;

[0025] A fixing structure 2 is installed on the bottom surface of the wear-resistant layer 11. The fixing structure 2 includes a shell 21, which is sewn to the bottom surface of the wear-resistant layer 11. A sleeve 22 is fixedly installed on the surface of the shell 21 by threads. A rope drum 23 and a worm gear 26 are movably installed on the inner side of the shell 21 through bearings. A binding rope 24 is wound on the rope drum 23. A worm wheel 25 is fixedly connected to one end of the rope drum 23. A motor 27 is fixedly installed on the inner side of the shell 21. By sewing the shell 21 to the bottom surface of the wear-resistant layer 11, the fixing structure 2 can be fixed to the bottom surface of the tarpaulin body 1 without damaging the surface of the tarpaulin body 1. In use, the fixing structure 2 is located on the inner side of the tarpaulin body 1, which can prevent the fixing structure 2 from being corroded by rainwater and rusting, thus ensuring the service life of the fixing structure 2.

[0026] Furthermore, the fixing structure 2 is provided in four sets, which are located at the four corners of the bottom surface of the wear-resistant layer 11. When covering goods, the four sets of fixing structures 2 can stretch and position the four corners of the tarpaulin body 1 and the wear-resistant layer 11 respectively, so as to prevent the covered tarpaulin body 1 and the wear-resistant layer 11 from being blown away by the wind and causing inconvenience.

[0027] Furthermore, the sleeve 22 is trumpet-shaped, and the inner diameter of the small end of the sleeve 22 is smaller than the diameter of the binding rope 24. When the binding rope 24 is retracted into the inner side of the outer shell 21, the sleeve 22 can pull down the rainwater on the binding rope 24, preventing a large amount of rainwater from entering the outer shell 21 and accelerating the damage to the fixing structure 2.

[0028] Furthermore, the binding rope 24 passes through the outer shell 21 via the loop 22, which provides a channel for the binding rope 24 to move inside and outside the outer shell 21.

[0029] Furthermore, the worm 26 meshes with the worm wheel 25, and the rotation of the worm 26 can drive the rope drum 23 to rotate through the worm wheel 25, thereby enabling the rope 24 to be wound or unwound on the rope drum 23.

[0030] Furthermore, the output end of the motor 27 is fixedly connected to the worm gear 26, and the motor 27 provides power for the rotation of the worm gear 26.

[0031] Working principle: The wear-resistant layer 11 is set on the bottom surface of the tarpaulin body 1, and the outer shell 21 is fixed to the bottom surface of the wear-resistant layer 11 by stitching. When the tarpaulin body 1 is used to cover the goods on the truck, the wear-resistant layer 11 is located inside the tarpaulin body 1. The tarpaulin body 1 can play a rainproof role, and the outer shell 21 can be located inside the tarpaulin body 1, which can prevent the components inside the outer shell 21 from being affected by rainwater and extend the service life of the fixing structure 2. At the same time, the fixing structure 2 is relatively heavy. The four sets of fixing structures 2 are located at the four corners of the bottom surface of the wear-resistant layer 11. When covering the goods, the four sets of fixing structures 2 can stretch and position the four corners of the tarpaulin body 1 and the wear-resistant layer 11 respectively, so as to prevent the covered tarpaulin body 1 and the wear-resistant layer 11 from being blown away by the wind and causing inconvenience.

[0032] The starting motor 27 can drive the worm 26 to rotate. The worm 26 meshes with the worm wheel 25. The rotation of the worm 26 can drive the rope drum 23 to rotate through the worm wheel 25, so that the binding rope 24 can be wound or unwound on the rope drum 23. When the binding rope 24 is wet by rain, the motor 27 can drive the rope drum 23 to be wound into the outer shell 21. The binding rope 24 moves in the sleeve 22, which can wipe off the rainwater on the surface of the binding rope 24, preventing a large amount of rainwater from entering the outer shell 21 and accelerating the damage to the fixing structure 2.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description.
