Description

Technical Field

[0001] This utility model relates to the technical field of cargo protection equipment for trucks, and in particular to a truck rainproof cloth covering device with a quick-fixing structure. Background Technology

[0002] The truck tarpaulin covering device is a mechanized device installed on the top of the truck bed. Its core function is to automatically unfold / retract the tarpaulin and achieve rapid and stable fixation. It mainly consists of a main structure, a drive system, and a fixing structure.

[0003] Existing truck tarpaulin covering devices require multiple people to work together to complete the processes of laying the tarpaulin and tying ropes, which is time-consuming. Furthermore, traditional ropes or hooks are prone to loosening when the vehicle is bumpy, causing the tarpaulin to shift and thus reducing its overall covering effect and affecting its overall efficiency. Therefore, this application provides a truck tarpaulin covering device with a quick-fixing structure to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide a truck tarpaulin covering device with a quick-fixing structure, which solves the technical problems of low laying efficiency and poor fixation of truck tarpaulins in the prior art, and achieves the effect of quick covering with one-button operation and zero loosening of tarpaulin under strong bumpy conditions.

[0005] To achieve the above objectives, this application provides the following technical solution: a truck rainproof cloth covering device with a quick-fixing structure, comprising a fixed horizontal plate and a placement frame. Connecting longitudinal plates are fixedly connected to both sides of the fixed horizontal plate, and the two connecting longitudinal plates form a concave structure with the fixed horizontal plate. A connecting plate is slidably connected to the free end of each connecting longitudinal plate. A drive motor is fixedly connected inside the fixed horizontal plate, and a drive shaft is fixedly connected to each of the two output ends of the drive motor. A movable steel cable is wound around the drive shaft, and a connecting member is fixedly connected to the free end of the movable steel cable. The drive motor drives the connecting member to move. A placement shaft is provided inside the placement frame through a tapered flared baffle, and a rainproof cloth is wound around the placement shaft. The rainproof cloth is fixedly connected to the top of the connecting member. Mounting frames are fixedly connected to both sides of the placement frame, and a fixing plate is rotatably connected to the mounting frame. The fixing plate is used to limit the position of the rainproof cloth.

[0006] Preferably, a limiting plate is slidably connected to the connecting longitudinal plate, and a limiting component is connected inside the limiting plate via an electric push rod. Both the connecting longitudinal plate and the connecting plate are provided with multiple limiting grooves, and the limiting component is inserted into the inside of the limiting groove.

[0007] Preferably, the connecting longitudinal plate is fixedly connected to a plurality of reinforcing ribs on its periphery, and the sidewall of the limiting plate is fixedly connected to a reinforcing member, wherein the reinforcing ribs and the reinforcing member are engaged and connected.

[0008] Preferably, anti-slip pads are fixedly connected to both the inside of the limiting groove and the limiting member, and two adjacent reinforcing members are in contact with each other.

[0009] Preferably, the fixed cross plate is internally fixed with a protective component, and the protective component is made of an elastic material.

[0010] Preferably, mounting holes are provided on both sides of the fixed horizontal plate, and a bearing sleeve is fixedly fitted inside the mounting hole, and the drive shaft is rotatably connected inside the bearing sleeve.

[0011] Preferably, the placement rack has multiple insertion cavities on both sides, and the side wall of the fixing plate is provided with insertion pins, which are inserted into the inside of the insertion cavities.

[0012] In summary, the technical effects and advantages of this utility model are as follows: This utility model features a rational structure. The frame width can be flexibly adjusted to accommodate different cargo box sizes by manually sliding the connecting plate along the connecting longitudinal plate. Simultaneously, when the sliding limit plate reaches the target position, an electric push rod pushes the limit component into the limit groove of the connecting longitudinal plate or connecting plate. Anti-slip pads enhance friction and prevent slippage, forming a primary locking mechanism. The reinforcing components and ribs automatically engage, and adjacent reinforcing components abut against each other, forming distributed mechanical support to resist lateral torsion, constituting a secondary reinforcement. Together, they form a multi-level locking structure. Even with tools, the frame coverage can be manually adjusted, significantly improving the equipment's versatility. Furthermore, the (double locking mechanism of pins + buckles) combined with the anti-slip design effectively suppresses frame deformation during vehicle vibration, preventing structural loosening. The distributed layout of the reinforcing ribs and engaging components disperses localized stress throughout the overall frame, enhancing resistance to wind pressure and cargo impact.

[0013] In this invention, by starting the drive motor, the dual drive shafts synchronously wind up the moving steel cable, and the traction connector slides along the frame, simultaneously unfolding the rainproof cloth to cover the cargo compartment. Simultaneously, the rotating fixing plate presses the edges of the rainproof cloth, and the insertion pins are inserted into insertion cavities at different heights to adapt to the cloth tension, forming a lateral constraint. The winding of the steel cable provides continuous tension, keeping the rainproof cloth taut at all times. The elastic protective component buffers the vibration of the steel cable, preventing wear and breakage, and forming longitudinal stability, thus creating an anti-loosening anchor. This allows for synchronous traction of the dual steel cables by a single motor during use, achieving "one-click deployment / retraction" of the rainproof cloth, saving labor time. The lateral pin anchoring combined with the longitudinal steel cable pre-tension forms a two-way constraint, completely eliminating cloth displacement caused by bumps. The elastic protective component also reduces steel cable fatigue wear, extending system life. Furthermore, the rotating pin design of the fixing plate eliminates the need for binding tools, allowing a single person to tighten the cloth edges. Attached Figure Description

[0022] The following is combined Figure 1-5 The embodiments shown illustrate the technical solution of this utility model: The device includes a fixed horizontal plate 1 and a placement frame 8. Both sides of the fixed horizontal plate 1 are fixedly connected to connecting vertical plates 2, and the two connecting vertical plates 2 form a concave structure with the fixed horizontal plate 1. The free ends of the connecting vertical plates 2 are slidably connected to connecting plates 3. The interior of the fixed horizontal plate 1 is fixedly connected to a drive motor 4, and the two output ends of the drive motor 4 are respectively fixedly connected to drive shafts 5. A moving steel cable 6 is wound on the drive shaft 5, and the free end of the moving steel cable 6 is fixedly connected to a connector 7. The drive motor 4 drives the connector 7 to move. The placement frame 8 has a placement shaft set inside through a tapered flared baffle, and a rainproof cloth 9 is wound on the placement shaft. The rainproof cloth 9 is fixedly connected to the top of the connector 7. Both sides of the placement frame 8 are fixedly connected to mounting frames 10, and a fixed plate 11 is rotatably connected to the mounting frame 10. The fixed plate 11 is used to limit the position of the rainproof cloth 9.

[0023] During its use, the fixed horizontal plate 1 is placed directly on a flat surface, allowing the connecting plate 3 to be pulled independently according to the actual needs of different occasions. This enables the connecting plate 3 to effectively slide along the connecting vertical plate 2, thereby adjusting the relative position between the connecting vertical plate 2 and the connecting plate 3 to meet the usage requirements of different specifications and increase its overall flexibility of use. After adjustment, the drive motor 4 is directly controlled by an external controller, causing the drive motor 4 to independently drive the moving steel cable 6 to wind. During the winding of the moving steel cable 6, its winding force will act on the connecting member 7, causing the connecting member 7 to be subjected to force along the connecting vertical plate 2 and the connecting vertical plate 3. The plate 3 slides, thereby changing the distribution position of the connector 7, so that the connector 7 can drive the rainproof cloth 9 to move autonomously, so that the rainproof cloth 9 can be effectively laid flat on the top of the fixed horizontal plate 1, the connecting vertical plate 2 and the connecting plate 3, thereby completing the rainproof cloth covering operation. Then, the fixed plate 11 limits the two sides of the rainproof cloth 9, thereby ensuring the overall stability of its use. During its winding, the tapered flared baffle at the end of the placement shaft of the placement frame 8 has its small end close to the placement shaft and its large end facing the rainproof cloth inlet. When the rainproof cloth is wound up, the tapered surface naturally guides the cloth to gather towards the shaft center, preventing the edges from getting stuck in the gap of the side wall of the placement frame.

[0024] A limiting plate 12 is slidably connected to the connecting longitudinal plate 2, and the interior of the limiting plate 12 is connected to a limiting component 14 via an electric push rod 13. Both the connecting longitudinal plate 2 and the connecting plate 3 have multiple limiting grooves 15, and the limiting component 14 is inserted into the interior of the limiting groove 15.

[0025] When the connecting longitudinal plate 2 and the connecting plate 3 are adjusted to a suitable position, the limiting plate 12 is pulled directly, so that the limiting plate 12 slides along the connecting longitudinal plate 2 under force. When it slides to a suitable position, the electric push rod 13 is directly controlled by the external controller, so that the electric push rod 13 effectively pushes the limiting member 14 to move, so that the limiting member 14 automatically inserts into the inside of the limiting groove 15. At this time, the insertion structure of the limiting member 14 and the limiting groove 15 will effectively limit the relative position between the connecting longitudinal plate 2 and the connecting plate 3, thereby improving the stability between the connecting longitudinal plate 2 and the connecting plate 3.

[0026] Multiple reinforcing ribs 16 are fixedly connected to the periphery of the connecting longitudinal plate 2, and a reinforcing member 17 is fixedly connected to the side wall of the limiting plate 12. The reinforcing ribs 16 and the reinforcing member 17 are engaged and connected.

[0027] When the limiting plate 12 fixes the connecting longitudinal plate 2 and the connecting plate 3, the reinforcement 17 on the side wall of the limiting plate 12 will effectively engage the reinforcing rib 16, thereby further reinforcing the position of the limiting plate 12 and effectively improving the overall stability of its adjustment.

[0028] Anti-slip pads 18 are fixedly connected to the inside of the limiting groove 15 and the limiting member 14, and two adjacent reinforcing members 17 are in contact with each other.

[0029] When the electric push rod 13 pushes the limiting member 14 to move, the anti-slip pad 18 on the limiting member 14 will directly contact the anti-slip pad 18 inside the limiting groove 15, thereby effectively limiting its overall position, improving its stability, and preventing it from sliding.

[0030] The fixed horizontal plate 1 is internally fixed with a protective component 19, and the protective component 19 is made of an elastic material.

[0031] During its use, the protective element 19 effectively improves the stability of the use of the moving steel cable 6, thereby preventing the moving steel cable 6 from being worn by stress, and thus effectively increasing the overall stability of its use.

[0032] Mounting holes are provided on both sides of the fixed horizontal plate 1, and bearing sleeves 20 are fixedly fitted inside the mounting holes, and the drive shaft 5 is rotatably connected inside the bearing sleeves 20.

[0033] During its use, the bearing sleeve 20 effectively prevents friction between the drive shaft 5 and the fixed horizontal plate 1, thereby effectively improving its overall service life.

[0034] The placement rack 8 has multiple insertion cavities 21 on both sides, and the side wall of the fixing plate 11 is provided with insertion pins 22, which are inserted into the inside of the insertion cavity 21.

[0035] Before use, pull the plug pin 22 directly, so that the plug pin 22 is slid out along the plug cavity 21 under force, that is, directly adjust the position of the fixing plate 11. When it is adjusted to a suitable position, insert the plug pin 22 again, so that the plug pin 22 is inserted into the plug cavity 21, thereby limiting the position of the fixing plate 11 and improving its overall stability.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
