Description

Technical Field

[0001] This utility model relates to the field of trailer technology, and in particular to a tarpaulin pole frame that is easy to fix and use. Background Technology

[0002] In modern logistics and transportation, semi-trailers are one of the main means of transportation, and the covering and protection of their cargo is of paramount importance. Semi-trailer tarpaulin frames are special equipment used to fix and support tarpaulins, mainly used in the semi-trailer transportation process to ensure that the cargo is effectively covered and protected during transportation.

[0003] Traditional tarpaulin poles require workers to unfold the tarpaulin from its stored state and cover the goods, a process that often necessitates multiple people working together. This is especially true when the tarpaulin area is large or when there is strong wind, making the operation even more difficult and reducing the ease of unfolding the tarpaulin on the pole. Therefore, those skilled in the art have provided a tarpaulin pole that is easy to fix and use, in order to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a tarpaulin pole frame that is easy to fix and use. Through the setting of the tensioning structure, it can ensure that the tarpaulin body is kept in a taut state and reduce the difficulty of the workers' work, thereby improving the ease of use between the tarpaulin pole frame and the tarpaulin body.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tarpaulin frame that is easy to fix and use, comprising a carriage and two fixing plates, wherein the two fixing plates are respectively disposed at the center of the side walls of the carriage, and a tensioning structure is provided at the center of the lower end face of the two fixing plates;

[0006] The tensioning structure includes two square grooves, which are respectively located at the center of the lower end face of two fixed plates. A rotary motor is provided at the upper center of the rear inner wall of each of the two square grooves. Multiple retaining rings are provided at the center of the outer side of one of the rotary motors. The multiple retaining rings are arranged in pairs, and the retaining rings in each pair are arranged in a front-to-back manner. A winding rope is wound and connected to the outer side of the rotating rod of the central rotary motor between the two retaining rings in each pair. Each end of the multiple winding ropes is provided with a buckle.

[0007] Multiple fixing blocks are arranged in a front-to-back pattern near the lower center of one side wall of the two fixing plates. Each fixing block has a support rod at the center of its upper surface and a fixing device at the center of its interior.

[0008] The above technical solution uses a rotating motor on one side to tighten the winding rope, ensuring that the tarpaulin body is also tightened as the winding rope tightens. This makes it easier for workers to unfold the tarpaulin body, reducing the difficulty of their work. Furthermore, the tension can be adjusted according to different pole heights to ensure that the tarpaulin body remains taut, achieving automated tensioning and untensioning of the tarpaulin and reducing the complexity and labor intensity of manual operation.

[0009] Furthermore, a tarpaulin body is wound around the center of the outer side of the rotating motor rod on the other side, and multiple buckles are arranged in a front-to-back pattern at the center of the lower end face of the tarpaulin body, with each buckle corresponding to a multiple locking buckle.

[0010] The above technical solution, by connecting the notch of the lock with the buckle, satisfies the connection between the two, enabling the winding rope to pull the tarpaulin body to unfold. When the tarpaulin body needs to be retracted, the lock is released, and the tarpaulin body is rolled up and stored by the rotating motor on the other side. This reduces the difficulty of the workers' work and improves the ease of use between the tarpaulin frame and the tarpaulin body.

[0011] Furthermore, the fixing device includes a slot, which is located at the center of the upper end face of the fixing block and is sleeved and connected to the end of the support rod. The slot has a first groove at the lower center of the center of both inner side walls, and a second groove at the lower center of the center of both side walls of the fixing block. A rubber clamping block is provided at the center of the inner side wall of each of the two first grooves, and the upper and lower ends of the center of one side wall of each of the two rubber clamping blocks are inclined surfaces.

[0012] With the above technical solution, when it is necessary to fix the support rod, it is inserted into the slot. The inclined design of the rubber clamping block allows the support rod to pass smoothly during the insertion process. The elasticity of the rubber clamping block makes it fit inside the second groove for limitation, thus satisfying the installation of the support rod and achieving its initial fixation.

[0013] Furthermore, each of the fixed blocks is provided with a screw at the lower center of the rear end face. The end of the screw passes through the fixed block and the support rod in sequence and extends to the front end face of the fixed block. A nut is threaded onto the outer center near the front end.

[0014] The above technical solution, through the penetration of the screw and the tightening of the nut, achieves secondary fixation of the support rod, ensuring the stability of the support rod, preventing it from loosening or slipping during use, and facilitating the installation and removal by staff, thereby improving the stability and convenience of its fixation.

[0015] Furthermore, each of the multiple support rods has an extension rod at the center of its upper end face, and each of the multiple support rods has an adjustment device at the center of one side wall. The adjustment device includes a sliding groove, which is located at the center of the upper end face of the support rod and is slidably connected to the extension rod. Each support rod has multiple first screw holes arranged vertically at the center of one side wall, which pass through one side wall of the support rod to the other side wall. Each extension rod has multiple second screw holes arranged vertically at the center of one side wall, which pass through one side wall of the extension rod to the other side wall. Two bolts are arranged vertically near the upper center of one side of the support rod.

[0016] The above technical solution allows for adjustment based on the height of different goods by using a sliding connection between the extension rod and the support rod.

[0017] Furthermore, the two bolts are threadedly connected to the first screw hole and the second screw hole, respectively;

[0018] The above technical solution uses a bolt to thread into the first and second screw holes, thus achieving the desired fixation of the extension rod after adjustment.

[0019] Furthermore, an arc-shaped rod is provided at the center between the upper end faces of the multiple extension rods on both sides, and a sleeve groove is provided at the center of the outer side of the multiple arc-shaped rods. A rubber block is provided at the upper center of the front and rear inner walls of the multiple sleeve grooves.

[0020] The above technical solution, by placing the winding rope in the groove and then limiting the winding rope with a rubber block, satisfies the guiding function of the winding rope. When the tarpaulin body is pulled, the winding rope gradually exits the groove, ensuring that the winding rope can smoothly unfold the tarpaulin body on the arc-shaped pole and preventing the tarpaulin body from shifting during unfolding, thereby improving the practicality of the tarpaulin pole frame.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when using the tarpaulin pole frame for easy fixing and use, the winding rope is tightened to ensure that the tarpaulin body can be tightened along with the winding rope, making it easier for workers to unfold the tarpaulin body and reducing the difficulty of their work. Furthermore, the tension can be adjusted according to different pole heights to ensure that the tarpaulin body remains taut, reducing the complexity and labor intensity of manual operation. The use of locks and buckles allows the winding rope to pull the tarpaulin body to unfold. By unlocking the locks and using the rotating motor on the other side to drive the tarpaulin body to roll up and store, the difficulty of workers' work is reduced, thereby improving the ease of use between the tarpaulin pole frame and the tarpaulin body.

[0023] 2. In this utility model, by fitting the winding rope into the groove and then limiting the winding rope with a rubber block, the winding rope is guided. When the tarpaulin body is pulled, the winding rope is gradually fitted out of the groove, which allows the winding rope to smoothly unfold the tarpaulin body on the arc-shaped pole and avoids the tarpaulin body from shifting during unfolding, thereby improving the practicality of the tarpaulin pole frame.

[0024] 3. In this utility model, when it is necessary to fix the support rod, it is inserted into the slot. The inclined design of the rubber clamping block allows the support rod to pass smoothly during insertion. The elasticity of the rubber clamping block allows it to fit inside the second groove for limitation, thus satisfying the installation of the support rod and achieving initial fixation. Then, the screw and nut achieve secondary fixation of the support rod, ensuring the stability of the support rod, preventing it from loosening or slipping during use, and facilitating the installation and removal by the staff, thereby improving the stability and convenience of its fixation.

[0033] 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.

[0034] Reference Figure 1-6 This utility model provides an embodiment of a tarpaulin pole frame that is easy to fix and use, including a carriage 1 and two fixing plates 2. The two fixing plates 2 are respectively set at the center of the two side walls of the carriage 1. A tensioning structure 3 is provided at the center of the lower end face of the two fixing plates 2. The tensioning structure 3 ensures that the tarpaulin body 306 is kept in a taut state and reduces the difficulty of the workers' work, thereby improving the ease of use between the tarpaulin pole frame and the tarpaulin body 306. Multiple fixing blocks 4 are arranged in a front-to-back pattern at the lower center of one side wall of the two fixing plates 2. A support rod 5 is provided at the center of the upper end face of each of the multiple fixing blocks 4. A fixing device 6 is provided at the center of the interior of each of the multiple fixing blocks 4.

[0035] The fixing device 6 includes a slot 601, which is located at the center of the upper surface of the fixing block 4 and is sleeved with the end of the support rod 5. The slot 601 has a first groove 602 at the lower center of the two inner side walls, and a second groove 603 at the lower center of the two side walls of the fixing block 4. A rubber clamping block 604 is provided at the center of the inner side wall of each of the two first grooves 602. The upper and lower ends of the center of one side wall of each of the two rubber clamping blocks 604 are inclined. When it is necessary to fix the support rod 5, it is inserted into the slot 601. The inclined design of the rubber clamping block 604 allows the support rod 5 to pass smoothly during insertion. The elasticity of the rubber clamping block 604 allows it to be sleeved inside the second groove 603 for limiting, thus satisfying the installation of the support rod 5 and achieving initial fixation.

[0036] Each of the fixed blocks 4 has a screw 605 located at the lower center of its rear end face. The end of the screw 605 passes through the fixed block 4 and the support rod 5 sequentially to the front end face of the fixed block 4. A nut 606 is threaded onto the outer center near the front end. Through the passage of the screw 605 and the locking of the nut 606, the support rod 5 is fixed in a secondary manner, ensuring the stability of the support rod 5 and preventing it from loosening or slipping during use. This also facilitates the installation and removal of the support rod by the staff, thereby improving the stability and convenience of its fixing.

[0037] Multiple support rods 5 are provided with extension rods 7 at the center of their upper end faces, and multiple support rods 5 are provided with adjustment devices 8 at the center of their side walls. The adjustment device 8 includes a slide groove 801, which is located at the center of the upper end face of the support rod 5 and is slidably connected to the extension rod 7. Multiple first screw holes 802 are arranged vertically at the center of one side of the support rod 5, and the multiple first screw holes 802 pass through one side wall of the support rod 5 to the other side wall of the support rod 5. Multiple second screw holes 803 are arranged vertically at the center of one side wall of the extension rod 7, and the multiple second screw holes 803 pass through one side wall of the extension rod 7 to the other side wall of the extension rod 7. Two bolts 804 are arranged vertically near the upper part of the center of one side of the support rod 5, and are slidably connected to the support rod 5 through the extension rod 7, so that they can be adjusted according to different cargo heights.

[0038] Two second bolts 803 are threadedly connected to the first screw hole 802 and the second screw hole 803 respectively. The bolt 804 is threadedly connected to the first screw hole 802 and the second screw hole 803 to satisfy the fixation of the extension rod 7 after adjustment.

[0039] An arc-shaped rod 9 is provided at the center between the upper surfaces of multiple extension rods 7 on both sides. A slot 10 is provided at the center of the outer side of multiple arc-shaped rods 9. A rubber block 11 is provided at the upper center of the inner walls of the front and rear of multiple slots 10. By fitting the winding rope 304 into the slot 10 and limiting the winding rope 304 with the rubber block 11, the winding rope 304 is guided. When the tarpaulin body 306 is pulled, the winding rope 304 is gradually fitted out of the slot 10. This allows the winding rope 304 to smoothly unfold the tarpaulin body 306 on the arc-shaped rod 9 and avoids the tarpaulin body 306 from shifting during unfolding, thereby improving the practicality of the tarpaulin frame.

[0040] like Figure 3As shown, the tensioning structure 3 includes two square grooves 301, which are respectively located at the center of the lower end face of the two fixed plates 2. A rotary motor 302 is located near the upper center of the inner rear wall of each square groove 301. Multiple retaining rings 303 are located at the center of the outer side of one of the rotary motors 302. The retaining rings 303 are arranged in pairs, with each pair arranged front-to-back. A winding rope 304 is wound and connected to the outer side of the rotating rod of the central rotary motor 302 between the two retaining rings in each pair. Each end of 304 is equipped with a latch 305. By rotating the motor 302 on one side, the winding rope 304 is tightened, so that the tarpaulin body 306 is also tightened as the winding rope 304 tightens. This makes it easier for workers to unfold the tarpaulin body 306, reducing the difficulty of the work. Furthermore, the tension can be adjusted according to different pole heights to ensure that the tarpaulin body 306 remains taut. This achieves automated tensioning and untensioning of the tarpaulin, reducing the complexity and labor intensity of manual operation.

[0041] A tarpaulin body 306 is wound and connected to the outer center of the rotating rod of the motor 302 on the other side. Multiple buckles 307 are arranged in a front-to-back pattern at the center of the lower end face of the tarpaulin body 306. The multiple buckles 307 are respectively set with multiple locks 305. The buckles 305 are connected to the buckles 307 through the notch of the lock, so that the connection between the two is satisfied. This allows the winding rope 304 to pull the tarpaulin body 306 to unfold. When the tarpaulin body 306 needs to be retracted, the locks 305 are released, and the tarpaulin body 306 is rolled up and stored by the rotating motor 302 on the other side. This reduces the difficulty of the work for the staff and improves the convenience of use between the tarpaulin frame and the tarpaulin body 306.

[0042] Working principle: When using the tarpaulin frame for easy fixing and use, the support rod 5 is inserted into the slot 601. The inclined design of the rubber clamping block 604 allows the support rod 5 to pass smoothly during insertion. The elasticity of the rubber clamping block 604 then limits its movement by fitting it inside the second groove 603, thus satisfying the installation of the support rod 5 and achieving initial fixing. The screw 605 passes through and the nut 606 locks in place, achieving secondary fixing of the support rod 5, ensuring its stability and preventing loosening or slippage during use. This also facilitates loading and unloading by workers, thereby improving the stability and convenience of fixing. The extension rod 7 slides between itself and the support rod 5, allowing it to be adjusted according to different cargo heights. The bolt 804 is threaded into the first screw hole 802 and the second screw hole 803, thus fixing the extension rod 7 after adjustment.

[0043] The rotation of the rotating motor 302 on one side causes the winding rope 304 to tighten, ensuring that the tarpaulin body 306 is also tightened as the winding rope 304 tightens. This facilitates the unfolding of the tarpaulin body 306 by the staff, reducing the difficulty of the work. Furthermore, the tension can be adjusted according to different pole heights to ensure that the tarpaulin body 306 remains taut, achieving automated tensioning and untensioning of the tarpaulin. This reduces the complexity and labor intensity of manual operation. The connection between the notch of the locking buckle 305 and the buckle ring 307 is achieved, allowing the winding rope 304 to pull the tarpaulin body 306 to unfold. When the tarpaulin body 306 needs to be retracted, the locking buckle 305 is released, and the rotating motor 302 on the other side drives the tarpaulin body 306 to roll it up and store it. This reduces the difficulty of the staff's work and improves the ease of use of the tarpaulin pole and the tarpaulin body 306.

[0044] By fitting the winding rope 304 into the groove 10 and then limiting the winding rope 304 with the rubber block 11, the winding rope 304 is guided. When the tarpaulin body 306 is pulled, the winding rope 304 is gradually fitted out of the groove 10. This allows the winding rope 304 to smoothly unfold the tarpaulin body 306 on the arc rod 9 and prevents the tarpaulin body 306 from shifting during unfolding, thereby improving the practicality of the tarpaulin frame.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
