Description

Technical Field

[0001] This utility model belongs to the field of sports equipment technology, specifically an adjustable height hurdle. Background Technology

[0002] Hurdling is an Olympic event that requires competitors to clear hurdles of a specified height and number over a certain distance. It is a technically demanding sprint event.

[0003] The approach run and hurdles movements in kindergarten physical activities are similar. The approach run and hurdles develop jumping ability, depth perception, and force perception, and improve the ability to regulate stride. Try hurdling with your child! Small hurdles are widely used in physical training, especially in sports like soccer that emphasize lower limb strength and agility, to limit the distance and height of jumps.

[0004] Currently available small-sized hurdles on the market are generally of fixed height. Even some height-adjustable hurdles are usually adjusted by rotating, which increases the number of parts and thus the total weight.

[0005] In summary, this utility model provides an adjustable-height hurdle to solve the above-mentioned problems. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides an adjustable-height hurdle, which solves the problem that increasing the usable height in the prior art increases the number of parts and thus the total weight.

[0007] An adjustable-height hurdle includes a soft band, with a band support plate fixedly connected to each end of the soft band. The band support plates are connected by a restraint strap. Two push sliders are fixedly connected to the bottom of each band support plate. A slide plate is provided below each push slider, and the push slider and the slide plate are slidably connected. A hurdle support leg is provided at the bottom of the same band support plate and is fixedly connected to the bottom of the slide plate. One side of the push slider is fixedly connected to one end of the slide plate by a restoring spring. The two hurdle support legs are fixedly connected by two reinforcing main rods.

[0008] Furthermore, the tension strip fixing plate has a binding strap through hole groove, one end of the binding strap passes through the binding strap through hole groove, one of the binding straps is connected to a binding strap adjustment buckle, and the other binding strap passes through the binding strap adjustment buckle and is connected to the surface of the same binding strap by a tension buckle.

[0009] Furthermore, a guide rail is installed on the surface of the slide plate, the bottom of the pushing slider is slidably connected to the surface of the guide rail, a limiting end plate is fixedly connected to one end of the slide plate, and the restoring spring is fixedly connected between the limiting end plate and the pushing slider.

[0010] Furthermore, the slide plates are respectively installed on both sides of the reinforcing main rod, and the slide plates are respectively installed at both ends of the reinforcing main rod.

[0011] Furthermore, the pushing sliders are respectively fixedly connected to both ends of the bottom of the tension strip fixing plate, and the bottom of the pushing sliders is slidably mounted on the guide rail.

[0012] Furthermore, the hurdle support leg has a "U" shaped structure, and one end of the hurdle support leg is fixedly connected to the bottom of the slide plate through a fixing lug.

[0013] Furthermore, the soft bandage has an arc-shaped structure, with a convex structure in the middle and the height of both ends being lower than the height of the middle.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model, by setting up a soft band, can change the height of the protrusion at the top of the band by changing the distance between the two ends of the band, thereby changing the horizontal height of the hurdle area and adjusting the height of the hurdle. The soft structure of the hurdle area serves to limit the height during use and also protects the trainee's legs during training, preventing them from contacting the hurdle and causing leg injuries.

[0016] 2. This utility model provides stable support for the soft hurdle strip by setting up a slide plate and hurdle support legs. The hurdle support legs have a U-shaped structure, which does not affect the stability when providing support, and does not obstruct the athlete's movement path in the event of a fall.

[0017] 3. This utility model has been approved. Attached Figure Description

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] like Figure 1-4 As shown, this utility model provides an adjustable height hurdle, including a soft band 1. Both ends of the soft band 1 are fixedly connected to band fixing plates 9. The band fixing plates 9 are connected to each other by a restraint strap 5. Two push sliders 7 are fixedly connected to the bottom of the band fixing plates 9. A slide plate 3 is provided below the push slider 7. The push slider 7 and the slide plate 3 are slidably connected. A hurdle support leg 4 is provided at the bottom of the same band fixing plate 9. The hurdle support leg 4 is fixedly connected to the bottom of the slide plate 3. One side of the push slider 7 is fixedly connected to one end of the slide plate 3 by a restoring spring 6. The two hurdle support legs 4 are fixedly connected by two reinforcing main rods 2.

[0026] As one embodiment of this utility model, the tension strip fixing plate 9 is provided with a binding strap through hole groove, one end of the binding strap 5 passes through the binding strap through hole groove, one binding strap 5 is connected to a binding strap adjustment buckle 10, and the other binding strap 5 passes through the binding strap adjustment buckle 10 and is connected to the surface of the same binding strap 5 by a tension buckle 11.

[0027] In one embodiment of this utility model, a guide rail 8 is installed on the surface of the slide plate 3, the bottom of the push slider 7 is slidably connected to the surface of the guide rail 8, a limiting end plate is fixedly connected to one end of the slide plate 3, and a restoring spring 6 is fixedly connected between the limiting end plate and the push slider 7.

[0028] In one embodiment of this utility model, slide plates 3 are respectively disposed on both sides of the reinforcing main rod 2, and slide plates 3 are respectively disposed at both ends of the reinforcing main rod 2.

[0029] In one embodiment of this utility model, the push slider 7 is fixedly connected to both ends of the bottom of the tension strip fixing plate 9, and the bottom of the push slider 7 is slidably arranged on the guide rail 8.

[0030] As one embodiment of this utility model, the hurdle support leg 4 has a "U" shaped structure, and one end of the hurdle support leg 4 is fixedly connected to the bottom of the slide plate 3 through a fixing ear.

[0031] As one embodiment of this utility model, the soft bandage 1 has an arc-shaped structure, the middle part of the soft bandage 1 has a convex structure, and the height of the two ends is lower than the height of the middle part.

[0032] Specific working principle:

[0033] The hurdle support leg 4 supports the soft support strip 1 on the ground, supporting the hurdle. When using it, the user steps over the highest point of the soft support strip 1.

[0034] When adjusting the height, pull one of the restraint straps 5 that is limited by the elastic buckle 11. Then the length of the restraint strap 5 decreases, and the two tension plates 9 are pulled closer to each other, which compresses the soft tension plate 1. The height of the convex surface of the soft tension plate 1 increases. If it is necessary to lower it, loosen the restraint strap 5 to separate the two tension plates 9 from each other, and then the height of the soft tension plate 1 decreases.

[0035] When the tension plate 9 moves, it is pushed towards the slider 7 and slids on the surface of the guide rail 8, and is pulled by the return spring 6.
