Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, and in particular to a detachable hurdle support for track and field. Background Technology

[0002] The core components of existing hurdle frames mainly consist of two parts: the base and the uprights. The base typically comprises a crossbeam and legs. The crossbeam uses square or round tubing and can have internal counterweights to adjust the center of gravity for stability. Both ends of the crossbeam are connected to the legs via connecting lugs, and currently, two screws are commonly used for detachable fixing. The uprights are mostly made of aluminum or welded tubing, with one end fixed to the hurdle panel and the other end connected to the legs. In conventional designs, the uprights are directly inserted into the mounting holes of the legs via a plug-in method. Some uprights use a foldable structure, where two screws (a rotating fixing screw and a limiting screw) achieve a folding connection with the legs.

[0003] The outriggers and crossbeams are fixed with screws, requiring tools. The uprights are fixed to the mounting holes in the outriggers by gravity. During adjustment and movement on the track, there is a risk that the uprights may detach from the outriggers. A few uprights with foldable structures are not fixed to the outriggers and crossbeams after folding and storage, and the shaking during transportation may cause wear to the surface coating or structural damage. At the same time, there is room for further optimization of the detachable design of screws. Therefore, designers need to design a detachable design where the outriggers and crossbeams automatically lock, a tool-free folding design for the outriggers and uprights, and a design that ensures that the outriggers and uprights do not shake after folding and storage. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a detachable hurdle support for athletic fields, which meets the requirements for tool-free quick assembly and disassembly of the legs and crossbeams, and tool-free folding and fixing of the legs and uprights, while also solving the problem of leg and upright swaying during folding, storage, and transportation.

[0005] The technical solution of this utility model is as follows:

[0006] A detachable hurdle support for athletic fields includes a base with symmetrically arranged columns on the base and hurdle panels connected to the upper part of the columns. The base includes two legs arranged in parallel intervals. Each leg is provided with a self-locking mechanism at one end near the column. The self-locking mechanism is used for tool-free detachable connection between the leg and the crossbar.

[0007] The self-locking mechanism includes a base connected to the support leg, an axial guide channel inside the base, a stop ring at one end of the guide channel, a locking pin passing through the guide channel, a return spring between the locking pin and the guide channel, one end of the return spring abutting the shoulder of the outer wall of the locking pin, the other end abutting the stop ring, and a handle hinged to the outer end of the locking pin through the stop ring outside the base.

[0008] The crossbar has locking holes at both ends that cooperate with the locking pin. A force-bearing inclined surface is provided next to the locking hole. When the crossbar is inserted into the support leg, the inner end of the locking pin slides along the force-bearing inclined surface until the locking pin is inserted into the locking hole. When disassembly is required, the locking pin is driven out of the locking hole by the handle axially.

[0009] Furthermore, a limiting protrusion extends from one side of the handle, and a pin is provided in the limiting protrusion. The outer end of the locking pin is provided with a mounting hole, and the pin is rotatably connected in the mounting hole. When the handle is rotated around the pin to a vertical position, the locking pin is inserted into the locking hole. When the handle is rotated around the pin to a horizontal position, the locking pin is disengaged from the locking hole.

[0010] Furthermore, the locking pin has a stepped shaft structure, including a pin rod and a pin head. The diameter of the pin head is larger than the diameter of the pin rod. The connection between the pin rod and the pin head forms the shaft shoulder. One end of the pin rod is connected to the handle through the pin shaft, and the other end is connected to the pin head. The outer wall of the pin head is provided with several limiting blocks spaced apart along the circumferential direction. The inner wall of the guide channel is provided with limiting grooves that cooperate with the limiting blocks, ensuring that the handle is in a vertical state, the locking pin is inserted into the lock hole, the handle is in a horizontal state, and the locking pin is disengaged from the lock hole.

[0011] Furthermore, the base is provided with symmetrical ear plates on both sides, and the ear plates are provided with through holes corresponding to the two sides of the support legs. The base and the support legs are connected by screws in the through holes, so that the self-locking mechanism can be disassembled and is easy to maintain and replace.

[0012] Furthermore, a folding hinge assembly is provided at the connection between the support leg and the column. The folding hinge assembly includes two fixing plates spaced apart on the upper end face of the support leg. The lower end of the column has a support arm located between the two fixing plates. One side of the lower end of the support arm is rounded. The support arm is rotatably connected to the fixing plate through a hinge shaft.

[0013] Furthermore, the two fixing plates are provided with shaft holes at corresponding positions, and the hinge shaft is detachably provided in the shaft holes. The support arm is provided with an axially shaped hole, and the hinge shaft passes through the axially shaped hole. The column slides axially along the axially shaped hole. When it slides to one end of the hinge shaft away from the column, the column rotates around the axial direction of the rounded corner to achieve folding. When the axially shaped hole slides to the other end, the lower end face of the support leg abuts against the upper end face of the base to achieve locking.

[0014] Furthermore, a suction cup is fitted around the outer periphery of the column. After the support leg and the column are folded, the suction cup is attached to the upper surface of the support leg, thus avoiding the problem of the support leg and the column shaking during transportation.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model features an innovative self-locking mechanism. When the support leg is connected to the crossbar, the locking pin can automatically slide into the lock hole along the inclined surface of the crossbar to lock it. When disassembling, only the handle needs to be turned to drive the locking pin out, without the need for tools such as screwdrivers, thus improving the efficiency of disassembly and assembly.

[0017] 2. This utility model connects the support legs and the column through a folding hinge assembly. The column with an oblong hole is axially slidable to adjust the rotation center and achieve folding and locking of the column. No screwdriver or other tools are needed. After folding, the suction cups on the outer periphery of the column tightly adhere to the upper surface of the support legs, avoiding the problem of the support legs and column shaking during transportation.

[0018] 3. This utility model ensures that the handle is in a vertical position, the locking pin is inserted into the lock hole, the handle is in a horizontal position, and the locking pin is disengaged from the lock hole by providing several limiting blocks at intervals along the circumferential direction on the outer wall of the pin head and providing limiting grooves on the inner wall of the guide channel that cooperate with the limiting blocks.

[0019] 4. This utility model features a base with two side ear plates connected to the support legs by bolts. The two fixed plates have shaft holes at corresponding positions, and a hinge shaft is detachably installed in the shaft holes. This allows the self-locking mechanism and the folding hinge assembly to be detachable, facilitating maintenance and replacement. Attached Figure Description
