Technical Field

[0001] The utility model belongs to the technical field of hurdle racks, and particularly relates to a hurdle rack for sports competitions with high safety performance. Background Art

[0002] Hurdling is a very healthy and interesting sports event. With the popularization of hurdling in primary and secondary schools, hurdle racks have become increasingly important sports equipment. Due to physical and psychological reasons, many people have a fear of hurdling. They are afraid of falling down by hitting the hurdle board with their legs during the hurdling process, and due to concerns about the safety of the hurdler, they are afraid of being tripped by the hurdle board. Therefore, many people dare not try and lose the opportunity to exercise through hurdling and experience the fun of the hurdling event. Moreover, during sports competitions, hurdling athletes may also make mistakes and knock down the hurdle rack, causing harm to themselves.

[0003] The existing CN220495592U discloses a hurdle rack for sports competitions, which includes two L-shaped blocks and two vertical rod tubes. Fixed slots are provided on one side surface of each of the two L-shaped blocks, and positive magnets are fixedly connected to the inner walls of the two fixed slots. A cross plate is in contact with the upper surfaces of the two L-shaped blocks. Two connecting slots are provided on one side surface of the cross plate, and negative magnets are fixedly connected to one side of the inner walls of the two connecting slots. Moving slots are provided on the upper surfaces of the two L-shaped blocks, and a long rod is fixedly connected to the opposite sides of the inner walls of the two moving slots. Bearing springs are in contact with the rod walls of the two long rods, and baffles are rotatably connected to the rod walls of the two long rods. Grooves are provided on the lower surfaces of the two baffles, and the inner walls of the two grooves are rotatably connected to the bearing springs. Two card slots are provided on one side surface of the cross plate;

[0004] When this hurdle rack is in use, the running speed of professional or non-professional athletes during hurdling is relatively fast. If the hurdling height is insufficient and a person touches the cross plate, the cross plate will be touched and fall off. If one accidentally steps on the fallen cross plate or is tripped by the fallen cross plate, it is easy to cause injury to the person. It has insufficient safety and low practicality at the same time. Summary of the Invention

[0005] The utility model provides a hurdle rack for sports competitions with high safety performance, aiming to solve the problem that when the existing hurdle rack is in use, the running speed of professional or non-professional athletes during hurdling is relatively fast. If the hurdling height is insufficient and a person touches the cross plate, the cross plate will be touched and fall off. If one accidentally steps on the fallen cross plate or is tripped by the fallen cross plate, it is easy to cause injury to the person. It has insufficient safety and low practicality at the same time.

[0006] An embodiment of the utility model provides a hurdle for a sports competition with high safety, which includes two bases. Both of the two bases are fixedly connected with mounting cylinders. A stretching component is also installed on the base. Telescopic rods are installed in both of the two mounting cylinders. A joint is installed on the telescopic rod. A cross bar is installed on the joint. The cross bar is made of high-density sponge. A magnetic attraction component is installed on the cross bar.

[0007] Furthermore, the two bases are connected by a connecting rod. The base is in a hollow shape, and a load-bearing block is arranged in the base.

[0008] By adopting the above technical solution, the two bases are connected by a connecting rod and there is a load-bearing block in the base, which can greatly improve the stability of the base and reduce the occurrence of accidents where the hurdler kicks over the entire hurdle.

[0009] Furthermore, the stretching component includes fixing plates fixedly connected to the base on both sides of the mounting cylinder. A winding roller is rotatably connected between the fixing plates. A stretching rope is wound on the winding roller. One end of the stretching rope is fixed on the winding roller. The winding roller extends to the outside of the fixing plate and is fixedly connected with a handle.

[0010] By adopting the above technical solution, the stretching rope can be stretched by rotating the handle.

[0011] Furthermore, the telescopic rod includes a fixed column threadedly connected to the mounting cylinder. A sliding rod is slidably connected in the fixed column. A plurality of through holes are provided on the fixed column. A sliding groove is provided on the rod body of the sliding rod. A sliding plate slides in the sliding groove. The sliding plate is connected to the bottom of the sliding groove by a spring. The other end of the sliding plate is fixedly connected with a blocking rod. The blocking rod can pass through the through hole.

[0012] By adopting the above technical solution, when the height of the hurdle needs to be adjusted, press the blocking rod by hand, press the blocking rod back into the sliding groove from outside the through hole, and then the blocking rod slides towards the sliding groove. At this time, the spring will be compressed due to extrusion. At this time, without the restriction of the blocking rod, the sliding rod can slide up and down in the fixed column until the blocking rod passes through the next through hole during the sliding process. When passing through the through hole, the blocking rod can pop out of the through hole again under the action of the spring, and then the sliding rod cannot be slid anymore, achieving the purpose of fixing the sliding rod in the fixed column.

[0013] Furthermore, the joint is provided with two openings. One of the openings is sleeved on the top of the sliding rod, and the other opening is movably connected to one end of the cross bar.

[0014] By adopting the above technical solution, the sliding rod and the cross bar can be quickly connected through the joint.

[0015] Further, the magnetic attraction assembly includes magnetic attraction blocks fixedly connected to the opposite surfaces of the two cross bars, and the other end of the stretching rope passes through the joint and the inside of the cross bar and is fixedly connected to the magnetic attraction block.

[0016] By adopting the above technical solution, the stretching rope can generate a force on the magnetic attraction block towards the two sliding bars, so that the cross bar made of high-density sponge will not bend towards the middle under the influence of the gravity of the magnetic attraction block, and the cross bar can be ensured to be in a horizontal state. At the same time, the two magnetic attraction blocks can generate an attractive magnetic force, which further ensures that the cross bar is in a horizontal state.

[0017] Further, the turning part of the joint is arc-shaped.

[0018] By adopting the above technical solution, the arc-shaped joint can prevent athletes or other personnel from being injured due to contact.

[0019] The beneficial effects of the present utility model are as follows:

[0020] 1. Through the arrangement of the cross bar and the joint of the present utility model, the cross bar made of high-density sponge can be connected to the sliding bar through the joint. When an athlete touches the cross bar during running, the cross bar will not fall off, and at the same time, the material of the cross bar is soft and will not cause harm to the athlete.

[0021] 2. Through the arrangement of the magnetic attraction assembly of the present utility model, the two magnetic attraction blocks can attract each other, thereby preventing the cross bar from bending towards the middle under the influence of the gravity of the magnetic attraction blocks.

[0022] 3. Through the arrangement of the stretching assembly of the present utility model, the stretching rope can be stretched by rotating the handle, and the stretching rope can pull the magnetic attraction block towards the two sliding bars, so that the cross bar made of high-density sponge will not bend towards the middle under the influence of the gravity of the magnetic attraction block, and the cross bar can be ensured to be in a horizontal state.

[0023] 4. Through the arrangement of the weight block of the present utility model, the stability of the base can be greatly improved, and the occurrence of the accident that the hurdler kicks over the entire hurdle is reduced.

Detailed implementation manners

[0031] In order to make the purpose, technical solutions and advantages of the technical solutions of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the drawings of the specific embodiments of the present utility model. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figures 1-4 , an embodiment of the present utility model provides a hurdle for a sports competition with high safety, including two bases 1, which are connected by a connecting rod 11 between the two bases 1. The base 1 is in a hollow shape, and a load block 12 is arranged in the base 1. The two bases 1 are connected by the connecting rod 11 and there is a load block 12 in the base 1, which can greatly improve the stability of the base 1 and reduce the occurrence of accidents where the hurdler kicks over the entire hurdle.

[0033] Refer to Figures 1-4, mounting cylinders 2 are fixedly connected to both bases 1, and a stretching assembly 3 is also mounted on the base 1. The stretching assembly 3 includes fixing plates 31 fixedly connected to the base 1 on both sides of the mounting cylinder 2. A winding roller 32 is rotatably connected between the fixing plates 31. A stretching rope 33 is wound around the winding roller 32. One end of the stretching rope 33 is fixed to the winding roller 32. The winding roller 32 extends to the outside of the fixing plate 31 and is fixedly connected to a handle 34. By rotating the handle 34, the stretching rope 33 can be stretched. Among them, the handle 34 has a self-locking function and can be self-locked after the stretching rope 33 is tightened or loosened, effectively avoiding the self-rotation of the winding roller 32 caused by the gravity of the crossbar 6 and the magnetic attraction block 71.

[0034] Refer to Figures 1-4 , telescopic rods 4 are installed in both mounting cylinders 2. The telescopic rod 4 includes a fixed column 41 threadedly connected to the mounting cylinder 2. A sliding rod 42 is slidably connected in the fixed column 41. A number of through holes 43 are provided on the fixed column 41. A sliding groove 44 is provided on the rod body of the sliding rod 42. A sliding plate 45 slides in the sliding groove 44. The sliding plate 45 is connected to the bottom of the sliding groove 44 by a spring 46. The other end of the sliding plate 45 is fixedly connected to a blocking rod 47. The blocking rod 47 can pass through the through hole 43. When the height of the hurdle needs to be adjusted, press the blocking rod 47 by hand, and press the blocking rod 47 from outside the through hole 43 back into the sliding groove 44. Then the blocking rod 47 slides into the sliding groove 44. At this time, the spring 46 will be compressed due to extrusion. At this time, without the restriction of the blocking rod 47, the sliding rod 42 can slide up and down in the fixed column 41 until the blocking rod 47 passes through the next through hole 43 during the sliding process. When passing through the through hole 43, the blocking rod 47 can pop out of the through hole 43 again under the action of the spring 46, and then the sliding rod 42 cannot be slid anymore, achieving the purpose of fixing the sliding rod 42 in the fixed column 41.

[0035] Refer to Figures 1-4, a joint 5 is installed on the telescopic rod 4. The joint 5 has two openings. One opening is sleeved on the top of the sliding rod 42, and the other opening is movably connected to one end of the cross bar 6. The sliding rod 42 and the cross bar 6 can be quickly connected through the joint 5. The turning part of the joint 5 is arc-shaped. The arc-shaped joint 5 can prevent athletes or other people from being injured by touching. The cross bar 6 is installed on the joint 5. The cross bar 6 is made of high-density sponge. A magnetic attraction component 7 is installed on the cross bar 6. The magnetic attraction component 7 includes magnetic attraction blocks 71 fixedly connected to the opposite surfaces of the two cross bars 6. The other end of the stretching rope 33 passes through the joint 5 and the cross bar 6 and is fixedly connected to the magnetic attraction blocks 71. By straightening the stretching rope 33, a force can be generated to pull the magnetic attraction blocks 71 towards the two sliding rods 42, so that the cross bar 6 made of high-density sponge will not bend towards the middle under the influence of the gravity of the magnetic attraction blocks 71, and the cross bar 6 can be ensured to be in a horizontal state. At the same time, the two magnetic attraction blocks 71 can generate an attractive magnetic force to further ensure that the cross bar 6 is in a horizontal state.

[0036] The specific implementation method is as follows: When in use, first connect the cross bar 6 to one opening of the joint 5, and then sleeve the other opening of the joint 5 on the top of the sliding rod 42, so that the two magnetic attraction blocks 71 attract each other, and then the cross bar 6 made of high-density sponge becomes horizontal. Then, by pressing the blocking rod 47, the sliding rod 42 slides up and down in the fixed column 41, so as to adjust the height of the cross bar 6. After the adjustment is completed, turn the handle 34 to make the winding roller 32 wind up the stretching rope 33, so that the stretching rope 33 is straightened, and then a force is generated on the magnetic attraction blocks 71 to be pulled towards the two sliding rods 42, so that the cross bar 6 made of high-density sponge will not bend towards the middle under the influence of the gravity of the magnetic attraction blocks 71, and the cross bar 6 can be ensured to be in a horizontal state.
