Abstract

A foldable hurdle includes: a crossbar for forming the hurdle; a connector rotatably connected to the crossbar, the end of the connector having two mutually perpendicular mating grooves; a rotating assembly connecting the connector and the crossbar; and a vertical bar detachably connected to the connector, the vertical bar being arranged vertically. When in the hurdle state, the protrusion of the connector engages with the horizontally oriented mating groove. When the hurdle is not needed or for storage and transportation, pulling the crossbar causes the protrusion of the connector to disengage from the horizontally oriented mating groove. Then, rotating the crossbar downwards aligns the protrusion with the mating groove facing the ground. Releasing the force causes a spring to move the connector upwards, causing the protrusion to engage with the mating groove facing the ground, thus completing the switch between the two states.

[0001] This utility model relates to the field of hurdle equipment technology, and more specifically, to a foldable hurdle. Background Technology

[0002] Hurdling is an important sport in track and field. Hurdling requires the use of hurdle racks, which can also be used to train jumping ability.

[0003] Patent CN209885260U discloses a safety hurdle frame, the structure of which includes a base, uprights on both sides of the base, corners at the top of the uprights, and two horizontal bars, which are respectively installed at the corners on both sides by elastic connectors. The elastic connectors include a connector, a plug, a spring, a slider, and a steel cable. The connector includes a disc-shaped connector body and a cylindrical plug for inserting the horizontal bar. The plug has an inner cavity and a through hole in the connector body. The spring is located in the inner cavity, and the slider is located at the port in the inner cavity. The plug rests on the end face of the connector body for connecting with the corner. The steel cable passes through the spring and the through hole in the connector body. One end of the steel cable is connected to the slider, and the other end is connected to the connector.

[0004] The patented crossbar cannot be folded, resulting in a large shipping volume and weight, high shipping costs, and a relatively complicated installation process before the equipment can be used. Furthermore, it is not convenient to use, and adjusting its position requires moving the bracket. Summary of the Invention

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a foldable hurdle that has the function of folding and storing the crossbar.

[0006] A foldable hurdle includes: a crossbar for forming the hurdle; a connector rotatably connected to the crossbar, the end of the connector having two mutually perpendicular mating grooves; a rotating assembly connecting the connector and the crossbar; and a longitudinal bar detachably connected to the connector.

[0007] Furthermore, the connector includes a horizontal port and a vertical port, which are integrated into one unit, and the two mating grooves are located at the front end of the horizontal port.

[0008] Furthermore, a gap groove is provided in the transverse port, and the gap groove is located in the middle of the docking groove.

[0009] Furthermore, a first hole is provided on the side wall of the transverse port, and a first rivet is provided in the first hole, the first rivet penetrating the slot.

[0010] Furthermore, the top of the crossbar is provided with a connector, and the top of the connector is provided with a protrusion that can be inserted into the mating groove.

[0011] Furthermore, the bottom of the connector is located inside the crossbar, and a second rivet passes through the side wall of the crossbar, the second rivet also passing through the bottom side wall of the connector.

[0012] Furthermore, the rotating assembly includes a spring, a first hook, and a second hook, wherein the first hook is located at the top of the spring and the second hook is located at the bottom of the spring.

[0013] Furthermore, the first hook is rotatably connected to the first rivet, and the second hook is rotatably connected to the second rivet.

[0014] Furthermore, the longitudinal rod can be inserted into the vertical port, the vertical port having a second hole, the second hole being screwed with a screw that passes through the longitudinal rod.

[0015] Furthermore, a mounting base is provided at the bottom of the longitudinal rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] ① When in the hurdle-crossing state, the protrusion of the connector fits into the horizontal docking groove. When hurdle-crossing or storage and transportation are not required, pull the crossbar to cause the protrusion of the connector to disengage from the horizontal docking groove. Then, rotate the crossbar downward to make the protrusion align with the docking groove facing the ground. After releasing the force, the spring causes the connector to move upward to make the protrusion fit into the docking groove facing the ground, thus completing the switch between the two states.

[0018] ② During the production of this device, springs are used to connect the connectors, crossbars, and longitudinal bars together, so that the device can be transported and used without disassembling the crossbars. Placing the crossbars at the same level as the longitudinal bars can reduce the transportation volume or the amount of work required by on-site installation workers.

[0019] ③ When conducting hurdle training, the orientation of the crossbar can be directly changed to adjust the distance between adjacent hurdles, eliminating the need to disassemble or rotate the crossbar and improving training efficiency. Attached Figure Description

Detailed Implementation

[0027] 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.

[0028] like Figure 1 As shown, a foldable hurdle includes: a horizontal bar 1 for forming the hurdle; a connector 2 rotatably connected to the horizontal bar 1, the end of the connector 2 having two mutually perpendicular mating grooves 21; a rotating assembly 3 connecting the connector 2 and the horizontal bar 1; and a vertical bar 4 detachably connected to the connector 2, the vertical bar 4 being vertically arranged.

[0029] like Figure 2 , Figure 4 As shown, the connector 2 includes a horizontal port 22 and a vertical port 23, which are integrated. The horizontal port 22 is positioned horizontally, and the vertical port 23 is positioned vertically. Two mating grooves 21 are located at the front end of the horizontal port 22, with one mating groove 21 facing horizontally and the other mating groove 21 facing the ground.

[0030] A notch 221 is provided in the transverse port 22. The notch 221 is located in the middle of the mating groove 21. The notch 221 passes through the middle of the two mating grooves 21 and enters the interior of the transverse port 22. The shape of the notch 221 is not limited. The notch 221 can be square or circular.

[0031] A first hole 222 is provided on the side wall of the transverse port 22. The first hole 222 penetrates the side wall of the transverse port 22 and the two inner walls of the slot 221. A first rivet 223 is provided in the first hole 222. The first rivet 223 penetrates the slot 221. The first hole 222 is horizontal and the first rivet 223 is also horizontal.

[0032] like Figure 3 As shown, the top of the crossbar 1 is provided with a connector 11, and the top of the connector 11 is provided with a protrusion 111. The protrusion 111 is located on the outside of the crossbar 1, and the diameter of the protrusion 111 is the same as the diameter of the crossbar 1. The protrusion 111 can be inserted into the mating groove 21. The mating groove 21 is an annular recess, and a positioning block protrudes from the mating groove 21. The height of the positioning block is lower than the depth of the mating groove 21. The protrusion 111 is also provided with a groove corresponding to the positioning block. When the protrusion 111 is inserted into the mating groove 21, the positioning block also inserts into the groove. When the protrusion 111 is inserted into the mating groove 21, the positioning block reduces the rotation of the connector 11 and the crossbar 1.

[0033] The crossbar 1 is a hollow bar, and the bottom of the connector 11 is located inside the crossbar 1. A second rivet 112 passes through the side wall of the crossbar 1, and the second rivet 112 also passes through the bottom side wall of the connector 11. The second rivet 112 fixes the crossbar 1 and the bottom of the connector 11 together, preventing relative rotation and relative sliding between the connector 11 and the crossbar 1. The bottom of the connector 11 is also hollow, and the middle of the connector 11 is a vertically penetrating cylindrical channel.

[0034] like Figure 4 As shown, the rotating assembly 3 connects the connector 11 and the transverse port 22 together, allowing the crossbar 1 to rotate relative to the transverse port 22 without disengaging. The rotating assembly 3 includes a spring 31, a first hook 32, and a second hook 33. The spring 31 is located in the connector 11, the first hook 32 is located at the top of the spring 31, and the second hook 33 is located at the bottom of the spring 31.

[0035] The first hook ring 32 is rotatably connected to the first rivet 223. When the first rivet 223 is installed, the first rivet 223 passes through the first hook ring 32. The lower part of the first hook ring 32 rotates in the empty groove 221, and the spring 31 cannot be inserted into the empty groove 221. The second hook ring 33 is rotatably connected to the second rivet 112. When the second rivet 112 is installed, the second rivet 112 passes through the second hook ring 33. After the first hook ring 32 and the second hook ring 33 are installed, the spring 31 is in a stretched state, thereby making the connector 11 tightly fit against the mating groove 21. When in the hurdle-crossing state, the protrusion 111 of the connector 11 fits into the horizontally oriented docking groove 21. When hurdle-crossing or storage and transportation are not required, the crossbar 1 is pulled to cause the protrusion 111 of the connector 11 to disengage from the horizontally oriented docking groove 21. Then, the crossbar 1 is rotated downward to make the protrusion 111 align with the docking groove 21 facing the ground. After releasing the force, the spring 31 drives the connector 11 to move upward to make the protrusion 111 fit into the docking groove 21 facing the ground, thus completing the switch between the two states.

[0036] The outer wall of the crossbar 1 is fitted with a sponge sleeve 12 to reduce damage caused by impact when crossing the hurdle.

[0037] The longitudinal rod 4 can be inserted into the vertical port 23. The vertical port 23 is provided with a second hole 231. A screw 232 is screwed into the second hole 231. The screw 232 passes through the longitudinal rod 4, so that the longitudinal rod 4 can be connected to the vertical port 23 during production.

[0038] During the production of this device, spring 31 is used to connect the connector 2, the crossbar 1, and the longitudinal bar 4 together, so that the device can be transported and used without disassembling the crossbar 1. The crossbar 1 can be placed at the same level as the longitudinal bar 4, which reduces the transportation volume and the amount of work required by the on-site installation workers.

[0039] The bottom of the vertical bar 4 is equipped with a mounting base 5. The mounting base 5 is the same as the existing safety hurdle base. The screws and nuts for assembling the mounting base 5 can be successfully assembled by hand.

[0040] This device uses a crossbar 1 that does not need to be disassembled, eliminating the need for bolts to connect the connector 2 and the crossbar 1. Therefore, the accompanying bolt wrench is not required when selling the device, saving costs.

[0041] If the installation-free transportation method is used, taking a courier with a throw ratio of 8000 as an example, the volume weight of each hurdle frame is about 47kg, while the actual weight of the hurdle frame is only about 10kg. Using this device, only the lower iron frame needs to be assembled, saving on shipping and logistics costs.

[0042] like Figure 5 As shown, when performing hurdle training, the orientation of the crossbar 1 can be directly changed to adjust the distance between adjacent hurdles, eliminating the need to disassemble or rotate the crossbar 1 and improving training efficiency.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
