[0001] This utility model relates to the technical field of guardrail connectors, and in particular to a guardrail connector. Background Technology

[0002] Trampolines, as a type of exercise equipment that combines entertainment and fitness, are widely used in homes, amusement parks, sports venues, and other settings. However, there are certain safety risks involved in trampoline activities. Users (especially children) may fall off the edge of the trampoline due to loss of balance or excessive force during jumps, resulting in collisions, injuries, and other accidents. Therefore, safety protection structures are a core component of trampoline design, with the combination of safety nets and guardrails being the mainstream safety solution.

[0003] Traditional connection devices often use rigid structures with fixed dimensions, such as buckles, through holes, or bolt holes designed for guardrail tubes of a specific diameter. The dimensional parameters of these structures are strictly limited, and once the diameter of the guardrail tube changes, the original connection device cannot be matched.

[0004] In response to the technical problem that existing connecting devices have poor adaptability and cannot be compatible with guardrail tubes of different sizes, this application proposes a guardrail connector. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of existing connecting devices, which have poor adaptability and cannot be compatible with guardrail tubes of different sizes. The proposed guardrail connector can fix guardrail tubes of different sizes without the need to design a separate connecting device for guardrail tubes of specific sizes, which greatly improves the applicability of the device. In addition, the elastic band increases the elasticity of the protective net, reduces the impact force from rigid collisions, and reduces the risk of injury to users.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a guardrail connector, comprising a gourd head and a protective net, wherein a fixed cylinder is fixedly connected to the bottom end of the gourd head, a rotating shaft is rotatably connected to the inner wall of the fixed cylinder, the rotating shaft is connected to a threaded rod through a drive assembly, the outer wall of the threaded rod is rotatably connected to the inner wall of the fixed cylinder, the threaded rod is connected to a fixed plate through a fixed assembly, the rear end of the fixed plate is slidably connected to the inner wall of the fixed cylinder, two slots are opened on the inner wall of the gourd head, an elastic band is sleeved on the inner wall of the slots, and connecting PP straps are fixedly connected to both ends of the right side of the elastic band, and a protective net PP strap is fixedly connected to the left end of the protective net, the connecting PP strap being connected to the protective net PP strap through a connecting assembly.

[0007] Furthermore, the drive assembly includes a first bevel gear fixedly connected to the bottom end of the rotating shaft, a second bevel gear meshing with the outer wall of the first bevel gear, and a threaded rod fixedly connected to the front end of the second bevel gear.

[0008] Furthermore, the fixing assembly includes a slider threadedly connected to the outer wall of the threaded rod, the outer wall of the slider being slidably connected to the inner wall of the fixing cylinder, and L-shaped connecting rods fixedly connected to all four sides of the outer wall of the slider. The outer walls of the L-shaped connecting rods are slidably connected to the inner wall of the fixing cylinder, and a support rod is rotatably connected to the front end of each L-shaped connecting rod. The other end of each support rod is rotatably connected to the outer side of the fixing plate.

[0009] Furthermore, the connecting component includes placement holes formed on the outer wall of the protective PP belt and the outer walls of both ends of the connecting PP belt, and each placement hole has a phoenix eye fixedly connected to its inner wall, and the phoenix eyes are connected by fasteners.

[0010] Furthermore, the fasteners include nylon bolts, nylon washers, and nylon nuts.

[0011] Furthermore, the top of the shaft is provided with an internal hexagonal groove for rotating the shaft by means of a wrench.

[0012] Furthermore, the elastic band is U-shaped and passes through the gourd head.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, rotating the shaft can drive the threaded rod to rotate, and the threaded rod will drive the slider to move, thereby moving the four fixed plates towards the center of the fixed cylinder. This allows for the fixing of guardrail tubes of different sizes without the need to design a separate connecting device for guardrail tubes of specific sizes, greatly improving the applicability of the device.

[0015] 2. In this utility model, an elastic band is passed through the hoist head to connect the elastic band to the hoist head, and then the elastic band is connected to the PP belt of the guardrail with fasteners. When the guardrail tube and the protective net are connected together, an elastic band is added in the middle to improve the elasticity of the protective net, reduce the impact force from rigid collisions, and reduce the risk of injury to users.

[0022] 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.

[0023] Reference Figures 1-3 An embodiment of this utility model provides a guardrail connector, including a gourd head 1 and a protective net 16. A fixed cylinder 2 is fixedly connected to the bottom end of the gourd head 1. A rotating shaft 3 is rotatably connected to the inner wall of the fixed cylinder 2. A first bevel gear 4 is fixedly connected to the bottom end of the rotating shaft 3. A second bevel gear 5 is meshed with the outer wall of the first bevel gear 4. A threaded rod 6 is fixedly connected to the front end of the second bevel gear 5. The outer wall of the threaded rod 6 is rotatably connected to the inner wall of the fixed cylinder 2. A slider 7 is threadedly connected to the outer wall of the threaded rod 6. The outer wall of the slider 7 is slidably connected to the inner wall of the fixed cylinder 2. L-shaped connecting rods 17 are fixedly connected to all four sides of the outer wall of the slider 7. The outer walls of the L-shaped connecting rods 17 are slidably connected to the inner wall of the fixed cylinder 2. A support rod 8 is rotatably connected to the front end of each L-shaped connecting rod 17. The other end of the support rod 8 is rotatably connected to the outer side of a fixed plate 9. The rear end of the fixed plate 9 is slidably connected to the inner wall of the fixed cylinder 2.

[0024] Specifically, the top of the rotating shaft 3 is provided with an internal hexagonal groove. An internal hexagonal wrench is inserted into the internal hexagonal groove. Rotating the internal hexagonal wrench can make the rotating shaft 3 rotate. When the L-shaped connecting rod 17 moves forward, the side of the support rod 8 close to the L-shaped connecting rod 17 will also move forward, causing the other side of the support rod 8 to move towards the middle of the fixed cylinder 2, thereby pressing the fixed plate 9 towards the middle.

[0025] Reference Figure 1 , Figure 2 and Figure 4The inner wall of the gourd head 1 has two slots, and an elastic band 10 is fitted on the inner wall of the slots. Both ends of the elastic band 10 are fixedly connected to the connecting PP band 11. The left end of the protective net 16 is fixedly connected to the protective net PP band 12. The outer wall of the protective net PP band 12 and the outer walls of both ends of the connecting PP band 11 are provided with placement holes 13. The inner wall of the placement holes 13 is fixedly connected to the eyelets 14. The eyelets 14 are connected by fasteners 15, which include nylon bolts, nylon washers and nylon nuts. The top of the rotating shaft 3 is provided with an internal hexagonal groove for rotating the rotating shaft 3 by a wrench. The elastic band 10 passes through the gourd head 1 in a U-shape.

[0026] Specifically, PP tape is short for polypropylene braided tape. It is a strip-shaped product made of polypropylene as the main raw material through processes such as extrusion, stretching, and weaving. It is a common plastic woven material. In scenarios such as trampoline safety nets, PP tape is usually used for edge reinforcement, structural connection, or as a load-bearing carrier. The eyelet 14 is usually a small round accessory made of metal with a hole in the middle for nylon bolts to pass through. The edge is designed with a flange or inward roll, which can tightly wrap the edge of the PP tape through the hole. As an intermediate medium, the eyelet 14 can reduce the direct friction between the nylon bolt and the PP tape and extend its service life.

[0027] Working principle: In use, first fold the elastic band 10 into a U-shape, so that the connecting PP strips 11 at both ends of the elastic band 10 are on one side. Then, pass the two ends of the elastic band 10 through the two slots opened in the hoist head 1. Then, place the protective netting PP strip 12 on the protective netting 16 in the middle of the connecting PP strip 11 folded to one side, so that the eyelets 14 are aligned. Then, fix the multiple eyelets 14 together with the fasteners 15, so that the connecting PP strip 11 and the protective netting PP strip 12 are connected together, so that the protective netting 16 is connected to the hoist head 1. Then, insert the guardrail tube into the middle of the fixing cylinder 2. Then, rotate the internal hexagonal slot with a tool to make the rotating shaft 3 rotate. The rotating shaft 3 drives the first bevel gear 4 to rotate, and the first bevel gear 4 drives the second bevel gear 5 to rotate, so that the threaded rod 6 rotates. The threaded rod 6 drives the slider 7 to move forward, so that the slider 7 drives the four L-shaped connecting rods 17 on the sides to move forward. The L-shaped connecting rods 17 then press the fixing plate 9 towards the middle of the fixing cylinder 2 through the support rod 8, so that the fixing plate 9 fixes the guardrail tube.

[0028] 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.
