Description

Technical Field

[0001] This utility model relates to the field of composite board transportation auxiliary equipment, and in particular to a fixing device for preventing cracking during composite board transportation. Background Technology

[0002] Composite boards are a type of composite material made by laminating multiple layers of boards together with adhesives and curing them under high temperature and high pressure. They have good strength and stability and can withstand large loads. Therefore, composite boards are widely used in the construction industry, such as floor slabs, wall panels, and roof panels.

[0003] During transportation, laminated panels need to be secured and limited using straps. The edges of the laminated panels that come into contact with the straps are easily damaged. Currently, a laminated panel fixing bracket (publication number CN221438749U) has been developed, which includes a bracket and elastic pads. When in use, the bracket is placed on top of the laminated panel, so that all the elastic pads are in contact with the laminated panel. Then, the straps are used to secure the laminated panel to the transport vehicle along the strap grooves. The force of the straps acts directly on the bracket, and then through the bracket and elastic pads to the laminated panel. The straps no longer come into direct contact with the edges of the laminated panel, thus avoiding wear on the edges of the laminated panel.

[0004] Existing composite slab fixing brackets have elastic feet that slide on the bracket's track via locking components. Although the position of the elastic feet can be adjusted to accommodate composite slabs of different specifications, the locking components are screw and nut structures. By adjusting the tightening / loosening of the screws and nuts, the locking components can be locked to the bracket or allowed to slide along the track on the bracket. Adjusting the screws and nuts requires tools such as wrenches, making the adjustment process cumbersome and easily loosened by vibration. Utility Model Content

[0005] To address the technical problems of existing fixed supports for transporting composite slabs, where the pressing structure uses screws and nuts to lock or unlock the position, resulting in a cumbersome adjustment process and easy loosening, this utility model provides a fixing device for preventing cracking during the transport of composite slabs.

[0006] The technical solution of this utility model is as follows:

[0007] This utility model provides a fixing device for preventing cracking during the transportation of composite slabs, including a bracket with connecting parts at both ends. A slide rail is formed along the length of the bracket, and several position adjustment components are slidably arranged within the slide rail. A first limiting groove is formed along the length of the slide rail on its side wall, and several second limiting grooves are formed above the first limiting groove. The second limiting grooves are spaced apart along the length of the slide rail and vertically penetrate the top of the bracket. Each position adjustment component includes a connecting rod, with a rubber pad fixedly connected to the bottom end of the connecting rod and a limiting cap movably connected to the top end of the connecting rod. A first limiting part that mates with the first limiting groove is fixedly provided on the side wall of the connecting rod, and a second limiting part that mates with the second limiting groove is fixedly provided on the side wall of the limiting cap. The limiting cap, through the interaction of the second limiting part and the second limiting groove, enables quick locking or unlocking operations. The overall operation is simple and convenient, requiring no auxiliary tools, facilitating the adjustment of the rubber pad's position, and making the fixing device more convenient to use.

[0008] Preferably, the slide rail includes a first slide rail and a second slide rail that are connected. The first slide rail is located directly below the second slide rail. The width of the first slide rail is smaller than that of the second slide rail to facilitate the engagement between the connecting rod, the limiting cap and the corresponding limiting groove, and to prevent the connecting rod from shaking.

[0009] Preferably, the first limiting groove is formed on the side wall of the first slide rail, and the second limiting groove is formed on the side wall of the second slide rail, so that the first limiting groove and the second limiting groove can cooperate with the first limiting part on the corresponding connecting rod and the second limiting part on the limiting cap.

[0010] Preferably, the top of the connecting rod is inserted into the limiting cap, the top of the connecting rod is fixedly provided with a flange, and the bottom opening of the limiting cap is fixedly provided with a baffle. The flange contacts the baffle, and the cooperation between the flange and the baffle can prevent the limiting cap from falling off the connecting rod.

[0011] Preferably, a spring is provided between the cap and the connecting rod, with the two ends of the spring being fixedly connected to the inner wall of the cap and the top of the connecting rod, respectively. This allows the cap to be reset with the assistance of the spring, making it convenient to use.

[0012] Preferably, the connecting part is fixedly located at the center of both ends of the bracket to ensure uniform force distribution.

[0013] Preferably, the bracket has at least one slide rail, which can increase the number and range of contact points with the composite plate to accommodate composite plates of larger specifications.

[0014] As can be seen from the above technical solutions, the advantages of this utility model are:

[0015] 1. The connecting rod is slidably mounted inside the slide rail. The connecting rod engages with the first limiting part and the first limiting groove through the first limiting part. While ensuring that the connecting rod moves along the slide rail, the axial position of the connecting rod is limited. The limiting cap is slidably mounted on the top of the connecting rod, and the limiting cap engages with the vertically set second limiting groove through the second limiting part. By moving the limiting cap upward, the second limiting part disengages from the second limiting groove, thereby unlocking the movement of the connecting rod. By resetting the limiting cap, the second limiting part inserts into the second limiting groove, thereby locking the movement of the connecting rod. The overall operation is simple and convenient, and no auxiliary tools are required. It is convenient to adjust the position of the rubber pressure pad, and the overall use of the fixing device is more convenient.

[0016] 2. A flange is fixedly provided at the top of the connecting rod, and a baffle is fixedly provided at the bottom opening of the limiting cap. The flange contacts the baffle. Through the cooperation of the flange and the baffle, the limiting cap can be prevented from falling off the connecting rod. A spring is provided between the cap and the connecting rod, which can assist the limiting cap in resetting, making it convenient to use. Attached Figure Description

[0024] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0025] Example

[0026] In a typical embodiment of this utility model, such as Figures 1-4 As shown, a fixing device for preventing cracking during the transportation of composite slabs is proposed, comprising: a bracket 1, a position adjustment component 2, and a rubber pad 3. The bracket 1 has connecting parts 13 fixed at both ends for connecting with ropes. The connecting parts 13 have rounded chamfers to reduce wear with the ropes. The bracket 1 has a slide rail. The position adjustment component 2 is slidably disposed in the slide rail of the bracket 1. The rubber pad 3 is fixedly installed at the bottom of the position adjustment component 2. The position of the rubber pad 3 can be adjusted by the position adjustment component to accommodate composite slabs of different specifications.

[0027] like Figure 4 As shown, the slide rail section includes a first slide rail 4 and a second slide rail 5. The first slide rail 4 is located directly below the second slide rail 5 and is connected to the second slide rail 5. The first slide rail 4 and the second slide rail 5 are vertically penetrating the bracket 1. Both the first slide rail 4 and the second slide rail 5 extend along the length of the bracket 1. The width of the first slide rail 4 is smaller than that of the second slide rail 5.

[0028] The position adjustment component 2 includes a connecting rod 8 and a limiting cap 9. The connecting rod 8 is vertically slidably disposed within the first slide rail 4 and the second slide rail 5, and the bottom end of the connecting rod 8 extends outward from the first slide rail 4 and is fixedly connected to the rubber pressure pad 3. The limiting cap 9 is slidably sleeved on the top end of the connecting rod 8 and can slide axially, thereby realizing the locking or unlocking of the position adjustment component 2 and the slide rail.

[0029] Specifically, a first limiting groove 6 is provided on the side wall of the first slide rail 4 along its length direction, and a first limiting part 14 is fixed on the side wall of the connecting rod 8. The first limiting part 14 is inserted into the first limiting groove 6, so that the connecting rod 8 can move along the length direction of the first slide rail 4 without moving axially, thereby preventing the connecting rod 8 from being pulled out or slipping.

[0030] like Figure 2As shown, a plurality of second limiting grooves 7 are provided on the side wall of the second slide rail 5. The second limiting grooves 7 are arranged vertically, so that the second limiting grooves 7 are perpendicular to the length direction of the second slide rail 5. The top of the second limiting grooves 7 penetrates the top of the bracket 1. The plurality of second limiting grooves 7 are arranged at equal intervals along the length direction of the second slide rail 5. A second limiting part 15 is fixedly provided on the side wall of the limiting cap 9. The second limiting part 15 is arranged horizontally and is inserted into the second limiting groove 7. Since the limiting cap 9 can slide along the axial direction of the connecting rod 8, when the limiting cap 9 is pulled upward, the second limiting part 15 can be pulled out from the second limiting groove 7, thereby removing the restriction on the connecting rod 8. The connecting rod 8 can move along the first slide rail 4. When the limiting cap 9 is released and it falls, the second limiting part 15 enters the corresponding second limiting groove 7 to restrict the movement of the connecting rod 8 and realize the locking of the overall position of the position adjustment component 2.

[0031] The setting of the limit cap 9, the second limit part 15, and the second limit groove 7 enables quick locking or unlocking operations. The overall operation is simple and convenient, and no auxiliary tools are required. It also facilitates the adjustment of the position of the rubber pressure pad 3, making the overall use of the fixing device more convenient.

[0032] like Figure 3 As shown, a flange 11 is fixedly provided at the top of the connecting rod 8. The top of the connecting rod 8 is inserted into the limiting cap 9. A baffle 12 is fixedly provided at the bottom opening of the limiting cap 9. The flange 11 contacts the baffle. Through the cooperation of the flange 11 and the baffle 12, the limiting cap 9 can be prevented from falling off the connecting rod 8. The inside of the limiting cap 9 is connected to the top of the connecting rod 8 through a spring 10. The two ends of the spring 10 are fixedly connected to the inner wall of the limiting cap 9 and the top of the connecting rod 8, respectively. The spring 10 can assist the limiting cap 9 in resetting.

[0033] In this embodiment, the connecting rod 8 and the limiting cap 9 are both rectangular structures to match the cross-sectional shapes of the first slide rail 4 and the second slide rail 5. In other embodiments, the connecting rod 8 and the limiting cap 9 can also be cylindrical structures, etc. The specific shapes are not restricted here.

[0034] The rubber pressure pad 3 is used to press the laminated plate. In this embodiment, the rubber pressure pad 3 is a rectangular block structure to ensure its pressing and limiting ability, and at the same time play a role in shock absorption. It is understood that in actual use, the rubber pressure pad 3 can also adopt the bowl-shaped structure in the prior art. No further restrictions are made here.

[0035] like Figure 1 As shown, the bracket 1 is provided with at least one slide rail. When several slide rails are provided, the slide rails are arranged at intervals along the width direction of the bracket 1, and several position adjustment components 2 are slidably arranged in each slide rail.

[0036] Understandably, in order to ensure uniform force distribution, the connecting part 13 is fixedly located at the center of both ends of the bracket 1.

[0037] The specific working principle is as follows:

[0038] Adjust the position of each rubber pad 3 according to the size of the composite plate. Specifically, first determine the position adjustment component 2 that needs to be adjusted, pull the corresponding limit cap 9 upward, so that the second limit part 15 disengages from the second limit groove 7, thereby releasing the lock on the position of the limit cap 9. Pull the limit cap 9 horizontally, and the limit cap 9 drives the connecting rod 8 and the rubber pad 3 below it to move along the first slide rail 4 and the second slide rail 5. When it moves into place, release the limit cap 9, so that the limit cap 9 automatically resets under the action of the spring 10 / gravity. At the same time, the second limit part 15 inserts into the adjacent second limit groove 7 to lock the position of the limit cap 9, thereby restricting the movement of the connecting rod 8, so that the rubber pad 3 can be quickly adjusted and locked, which is convenient for use. After all the specified rubber pad 3 positions are adjusted, place the entire fixing device on the composite plate and connect it with the connecting parts 13 at both ends of the bracket 1 using ropes. Connect the ropes through the connection position of the rope transport device, adjust the length of the ropes, and use the rubber pads 3 to apply downward force to press the composite plate.

[0039] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
