Sports hurdle with good protection effect

Abstract

The application discloses a sports hurdle frame with good protection effect, and relates to the technical field of sports goods. The sports hurdle frame with good protection effect comprises a hurdle frame assembly, a return assembly and a crossbar assembly. The crossbar assembly comprises two hurdle bars, and threaded slots are formed in opposite ends of the two hurdle bars. The sports hurdle frame with good protection effect has the advantages that the pressures sensed by multiple pressure sensors are compared with a threshold value. If the pressures do not reach the threshold value, the electromagnet is kept in an energized state, and the iron block is magnetically attracted to the electromagnet. Thus, the two hurdle bars are connected into a complete long bar. If the pressures exceed the threshold value, the electromagnet is instantaneously de-energized. When an athlete steps on the hurdle frame, the two hurdle bars can be quickly separated, and the athlete will not be tripped and fallen. Therefore, the hurdle frame has the advantage of protecting the athlete, and the problem that the existing hurdle frame body cannot be disassembled and easily causes the athlete to be hooked by the ankles and fallen is solved.

Description

Technical Field

[0001] This invention relates to the field of sports equipment technology, specifically to a sports hurdle with good protective effect. Background Technology

[0002] Sports hurdles are the core equipment in track and field hurdle events. They are used to set up obstacles of fixed height and spacing on the track for athletes to jump over during practice or competition. Their core function is to provide standardized obstacles for hurdle events. They must meet the fixed requirements of different events for hurdle height and width, and also minimize the risk of injury in case of accidental collisions. They are key equipment to ensure fair competition and safe training in hurdle events.

[0003] In existing technologies, the base, posts, and hurdles of traditional hurdles are mostly fixedly connected, forming an inseparable rigid whole. When an athlete's foot steps on the hurdle, the external force is directly transmitted to the entire frame. During the tilting process, the frame poses a risk of entanglement to the athlete. When the athlete is moving at high speed, their feet come into contact with the hurdle and their ankles are easily hooked by the hurdle, posts, or base, which can easily cause the athlete's heel to get caught, resulting in an imbalance and fall.

[0004] Therefore, we propose a sports hurdle with good protective effect to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a sports hurdle frame with good protective effect, so as to solve the problem mentioned in the background art that the existing sports hurdle frame is not detachable, which easily leads to athletes getting their ankles caught, losing balance and falling.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sports hurdle with good protective effect, comprising a hurdle assembly, a return assembly, and a crossbar assembly.

[0009] Preferably, a flexible elastic band is fixedly connected to the outer surface of both mounting blocks, and the flexible elastic band is used to make the fixing block and the hurdle spring back to their original position. A threaded fastening block is fixedly connected to one end of each of the two flexible elastic bands, and a positioning nut is threadedly connected to the outside of each of the two threaded fastening blocks.

[0010] Preferably, the hurdle frame assembly includes two load-bearing mechanisms and two support mechanisms. The load-bearing mechanism includes a water tank for storing clean water. The top of the water tank is fixedly connected to a water inlet, and the top of the water inlet is threadedly connected to a sealing cap.

[0011] Preferably, the support mechanism includes a support sleeve column, which is located at the top of the water tank. An adjusting slide rod is slidably connected to the inner wall of the support sleeve column. The flexible elastic band is movably embedded in the top of the adjusting slide rod, and the fixing block is in close contact with the adjusting slide rod.

[0012] Preferably, five adjustment slots are provided on one side of the adjustment slide rod, and a positioning hole is provided on the inner wall of one side of each adjustment slot. An adjustment positioning block is slidably connected to the inner wall of each positioning hole. A fixing spring is provided between one side of each adjustment positioning block and the inner wall of one side of each adjustment slot. A limiting telescopic rod is provided inside each fixing spring, and the two ends of the limiting telescopic rod are fixedly installed on one side of the adjustment positioning block and the inner wall of the adjustment slot, respectively.

[0013] Preferably, a positioning hole is provided on one outer surface of the support sleeve column, and the outer surface of the adjustment positioning block engages with the inner wall of the positioning hole. A limiting groove is provided on the other outer surface of the support sleeve column near its bottom. A slider is fixedly connected to the bottom of the adjusting slide rod, and the outer surface of the slider is slidably connected to the inner wall of the limiting groove. A telescopic rubber tube is fixedly connected between the inner bottom surface of the limiting groove and the bottom end of the adjusting slide rod, and the telescopic rubber tube is used to buffer the adjusting slide rod. Multiple air holes are provided on the outer surface of the telescopic rubber tube, and a buffer spring is provided on the outside of the telescopic rubber tube. The two ends of the buffer spring are fixedly connected to the bottom end of the adjusting slide rod and the inner bottom surface of the limiting groove, respectively.

[0014] Preferably, the return assembly includes a connecting mechanism and a spring-back mechanism. The connecting mechanism includes a first fixed blade and a second fixed blade. The first fixed blade is fixedly installed at the bottom of the support sleeve column by bolts, and the second fixed blade is fixedly installed at the corner of the water tank by bolts. A pin is movably connected between the first fixed blade and the second fixed blade. A high-elasticity torsion spring is provided on the outside of the pin, and the high-elasticity torsion spring is used to make the support sleeve column quickly spring back to its original position.

[0015] Preferably, the rebound mechanism includes two reinforcing blocks, which are respectively fixedly installed on the top of the water tank and the outer surface of the support sleeve. The inner walls of the two reinforcing blocks are fixedly connected to fixed rotating rods, and the outer surfaces of the two fixed rotating rods are rotatably connected to movable rotating blocks. A damping rod is fixedly connected between the two movable rotating blocks. A return spring is provided on the outside of the damping rod. The two ends of the return spring are respectively fixedly installed on one side of the two movable rotating blocks, and the return spring is used to pull back the tilted support sleeve and adjusting slide rod to their original positions.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. During use, multiple pressure sensors detect the pressure. If the pressure does not reach the threshold, the electromagnet remains energized and magnetically attracts the iron block, connecting the two hurdles into a single long bar. If the pressure exceeds the safe pressure threshold, the electromagnet is instantly de-energized. When the athlete steps on the bar, the two hurdles can quickly separate, breaking the connection in the middle and preventing the athlete from tripping. This protects the athlete and solves the problem that existing sports hurdle frames are not easily disassembled, which can lead to athletes getting their ankles caught, losing balance, and falling.

[0017] 2. When using the water tank, add water into the inlet to increase its weight, then tighten the sealing cap to prevent leakage. The full water tank can then be placed stably on the sports field. After positioning the two water tanks, adjust the height of the adjusting rod. The adjusting rod has five positions to meet the needs of different hurdlers. To adjust, press the adjusting positioning block inwards, simultaneously compressing the limiting telescopic rod and the fixing spring. When the adjusting positioning block aligns with the positioning hole, the fixing spring will push the block into the hole, thus positioning the adjusting rod and achieving its adjustment function. This allows for use by athletes of different heights.

[0018] 3. During use, the high-elasticity torsion spring can elastically push the first and second fixed blades back to their original positions, thereby restoring the tilted support sleeve and adjusting slide rod to their original positions. At the same time, the return spring will pull the support sleeve back, and with the elastic force of the high-elasticity torsion spring, the hurdle can automatically return to its original position when the athlete makes a mistake and the hurdle tilts during the hurdling exercise, without the need for manual return.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Refer to Figures 1-12As shown, the present invention provides a technical solution: a sports hurdle with good protective effect, including a hurdle assembly 1, a return assembly 2, and a crossbar assembly 3. The crossbar assembly 3 includes two hurdle bars 301, each with a threaded slot 302 at one opposite end. The inner walls of the two threaded slots 302 are threadedly connected to threaded connecting blocks 303. An iron block 305 is fixedly connected to the outer surface of one threaded connecting block 303, and an electromagnet 304 is provided on the outer surface of the other threaded connecting block 303. When energized, the electromagnet 304 is magnetically connected to the iron block 305. Each of the two hurdle bars 301 has an inner mounting compartment 312. A wire groove 315 is fixedly connected to one side of the inner wall of each of the two inner mounting compartments 312. An internal groove 314 is fixedly connected to one side of the inner wall of each of the two wire grooves 315. The inner walls of the two inner mounting compartments 312 are... Multiple pressure sensors 313 are provided, and controllers 316 are installed on the inner walls of the two built-in slots 314. The multiple pressure sensors 313 are used to monitor the pressure on the hurdles 301 during the hurdles event in real time. The controllers 316 are used to control the pressure sensors 313 and the electromagnets 304. The two hurdles 301 are fixedly connected to the opposite ends of each other with mounting slots 307. The outer surfaces of the two mounting slots 307 are provided with mounting slots 307. The inner walls of the two mounting slots 307 are fixedly connected to mounting blocks 308. The outer surfaces of the two mounting blocks 308 are fixedly connected to flexible elastic bands 309. The flexible elastic bands 309 are used to make the fixed blocks 306 and the hurdles 301 spring back to their original positions. One end of the two flexible elastic bands 309 is fixedly connected to a threaded fastening block 310. The outer surfaces of the two threaded fastening blocks 310 are threaded with positioning nuts 311.

[0023] In this embodiment, during use, when the hurdler sprints at high speed, the multiple pressure sensors 313 installed inside the mounting compartment 312 immediately sense the pressure the athlete experiences the moment their foot touches the hurdle 301. This pressure is then quickly transmitted to the controller 316. The controller 316 immediately receives the pressure signal and pre-sets a safe pressure threshold. If the athlete's trouser leg only brushes against the hurdle 301, the pressure value detected by the pressure sensor 313 is very small and does not reach the threshold. Therefore, the electromagnet 304 remains energized. The energized electromagnet 304 is magnetic and can magnetically attract the iron block 305. The threaded connecting block 303 connecting the electromagnet 304 and the iron block 305 is installed with each of the two hurdles 301, thus connecting the two hurdles 301 into a complete long pole. This long pole design improves the accuracy of the hurdle height measurement during hurdling. However, if the athlete fails to hurdle over the hurdle 301... Instead of stepping on the hurdle 301, the pressure sensor 313 at the point of impact will detect a pressure value exceeding the safe pressure threshold. The controller 316, receiving the pressure signal, will react promptly by instantly de-energizing the electromagnet 304. Once de-energized, the electromagnet 304 loses its magnetism, thus breaking its attraction to the iron block 305. When the athlete steps on it, the two hurdles 301 can quickly separate, disconnecting in the middle, preventing the athlete from tripping and thus protecting them. This solves the problem of existing sports hurdle frames being non-separable, which can easily cause athletes to lose balance and fall due to hooked ankles. By using a flexible elastic band 309 to connect the fixing block 306 and the adjusting slide rod 122, the hurdle 301 has an elastic buffering effect when subjected to large forces. Furthermore, the hurdle 301 is made of a soft material, allowing it to bend when the two hurdles 301 are disconnected, further protecting the hurdler.

[0024] Example 2: Figures 1-12As shown, the hurdle frame assembly 1 includes two load-bearing mechanisms 11 and two support mechanisms 12. The return assembly 2 includes a connecting mechanism 21 and a spring-loaded mechanism 22. The load-bearing mechanism 11 includes a water tank 110 for storing clean water. The top of the water tank 110 is fixedly connected to a water inlet 111, and the top of the water inlet 111 is threadedly connected to a sealing cap 112. The support mechanism 12 includes a support sleeve 120, which is located on the top of the water tank 110. An adjusting slide rod 122 is slidably connected to the inner wall of the 0. A flexible elastic band 309 is movably embedded in the top of the adjusting slide rod 122, and a fixing block 306 is tightly attached to the adjusting slide rod 122. Five adjusting slots 128 are opened on one side of the adjusting slide rod 122. A positioning hole 126 is opened on one side of the inner wall of each adjusting slot 128. A shifting positioning block 127 is slidably connected to the inner wall of each positioning hole 126. A fixing elastic band 306 is set between one side of each shifting positioning block 127 and the inner wall of each adjusting slot 128. Each fixed spring 129 has a limiting telescopic rod 124 inside, and the two ends of the limiting telescopic rod 124 are respectively fixedly installed on one side of the adjusting positioning block 127 and the inner wall of the adjusting groove 128. A positioning hole 126 is opened on one side of the outer surface of the support sleeve 120, and the outer surface of the adjusting positioning block 127 is engaged with the inner wall of the positioning hole 126. A limiting groove 121 is opened on the other side of the outer surface of the support sleeve 120 near its bottom. A slider is fixedly connected to the bottom of the adjusting slide rod 122. The outer surface of the slider is slidably connected to the inner wall of the limiting groove 121. A telescopic rubber tube 123 is fixedly connected between the inner bottom surface of the limiting groove 121 and the bottom end of the adjusting slide rod 122. The telescopic rubber tube 123 is used to buffer the adjusting slide rod 122. Multiple air holes are opened on the outer surface of the telescopic rubber tube 123. A buffer spring 125 is provided on the outside of the telescopic rubber tube 123. The two ends of the buffer spring 125 are fixedly connected to the bottom end of the adjusting slide rod 122 and the inner bottom surface of the limiting groove 121, respectively.

[0025] In this embodiment, during use, the support sleeve 120 and the water tank 110 are connected together using the connecting mechanism 21, preventing the hurdle frame from tipping over when the athlete hurdles. Water is injected into the water inlet 111, increasing the weight of the water tank 110. Then, the sealing cap 112 is tightened to prevent water leakage. The full water tank 110 can be stably placed on the sports field. After positioning the two water tanks 110, the next step is to adjust the height of the adjusting rod 122 to adjust the sliding... The lever 122 has five positions to meet the needs of different people for hurdling height. When adjusting, press the adjustment positioning block 127 inward, which will simultaneously compress the limiting telescopic rod 124 and the fixing spring 129. When the adjustment positioning block 127 corresponds to the position of the positioning hole 126, under the rebound action of the fixing spring 129, the adjustment positioning block 127 will be inserted into the positioning hole 126, thereby completing the positioning of the adjustment slide rod 122 and achieving the adjustment function of the adjustment slide rod 122, which can meet the needs of athletes of different heights.

[0026] Example 3: Figures 1-12 As shown, the hurdle frame assembly 1 includes two load-bearing mechanisms 11 and two support mechanisms 12. The return assembly 2 includes a connecting mechanism 21 and a spring-loaded mechanism 22. The connecting mechanism 21 includes a first fixing blade 210 and a second fixing blade 211. The first fixing blade 210 is fixedly installed at the bottom of the support sleeve column 120 by bolts, and the second fixing blade 211 is fixedly installed at the corner of the water tank 110 by bolts. A pin rod 213 is movably connected between the first fixing blade 210 and the second fixing blade 211. A high-elasticity torsion spring 212 is provided on the outside of the pin rod 213, and the high-elasticity torsion spring 212 is used to make the support sleeve column 120 quickly spring back to its original position. The rebound mechanism 22 includes two reinforcing blocks 220, which are fixedly installed on the top of the water tank 110 and the outer surface of the support sleeve 120, respectively. The inner walls of the two reinforcing blocks 220 are fixedly connected to fixed rotating rods 224, and the outer surfaces of the two fixed rotating rods 224 are rotatably connected to movable rotating blocks 221. The two movable rotating blocks 221 are fixedly connected to each other. The damping rods 222 are provided with return springs 223 on the outside. The two ends of the return springs 223 are fixedly installed on one side of the two movable rotating blocks 221, and the return springs 223 are used to pull back the tilted support sleeve 120 and the adjusting slide rod 122 to their original positions.

[0027] In this embodiment, during use, by installing the first fixed blade 210 and the second fixed blade 211 on the water tank 110 and the support column 120 respectively, when the athlete hurdles, stepping on the hurdle bar 301 or the adjusting slide bar 122 will exert a forward force. Since the connecting mechanism 21 is a rotating structure, the support column 120 and the adjusting slide bar 122 will tilt forward. The high-elasticity torsion spring 212 can elastically push the first fixed blade 210 and the second fixed blade 211 back to their original positions, so that the tilted support column 120 and the adjusting slide bar 122 will also return to their original positions. At the same time, the return spring 223 will pull the support column 120 back. With the elastic force of the high-elasticity torsion spring 212, when the athlete makes a mistake during the hurdling process and causes the hurdle bar 301 to tilt, the hurdle bar 301 can automatically return to its original position without manual return.

[0028] The usage and working principle of this device are as follows: During use, the supporting sleeve 120 and the water tank 110 are connected together using the connecting mechanism 21. This prevents the hurdle frame from tipping over during hurdling. Water is injected into the water inlet 111, increasing the weight of the water tank 110. Then, the sealing cap 112 is tightened to prevent water leakage. The full water tank 110 can be stably placed on the sports field. After positioning the two water tanks 110, the next step is to adjust the height of the adjusting slide bar 122. The adjusting slide bar 122 has five positions to meet the different hurdle height requirements of various individuals. During adjustment, the adjusting positioning block 127 is pressed inward, simultaneously compressing and shortening the limiting telescopic rod 124 and the fixing spring 129. When the positioning block 127 aligns with the positioning hole 126, under the rebound action of the fixing spring 129, the positioning block 127 will insert into the positioning hole 126, thus completing the positioning of the adjusting slide rod 122. In use, by installing the first fixing blade 210 and the second fixing blade 211 on the water tank 110 and the support column 120 respectively, when the athlete hurdles, stepping on the hurdle bar 301 or the adjusting slide rod 122 will exert a forward force. Since the connecting mechanism 21 is a rotating structure, the support column 120 and the adjusting slide rod 122 will tilt forward. The high-elasticity torsion spring 212 can elastically push the first fixing blade 210 and the second fixing blade 211 back to their original positions, thereby preventing the tilted support column 120 from tilting. The adjusting slide bar 122 also returns to its original position. Simultaneously, the return spring 223 pulls the support sleeve 120 back, and combined with the elasticity of the high-elasticity torsion spring 212, ensures that if the hurdle 301 tilts due to an athlete's mistake during hurdling, the hurdle 301 can automatically return to its original position. During use, when a hurdler sprints at high speed, the multiple pressure sensors 313 installed inside the inner chamber 312 immediately sense the pressure the hurdle experiences the moment their foot touches it. This pressure is then quickly transmitted to the controller 316. The controller 316 immediately receives the pressure signal and pre-sets a safe pressure threshold. If the athlete's trouser leg only brushes against the hurdle 301, the pressure value detected by the pressure sensor 313 will be very small. If the threshold is not reached, the electromagnet 304 remains energized. The energized electromagnet 304 is magnetic and can magnetically attract the iron block 305. The threaded connecting block 303 connecting the electromagnet 304 and the iron block 305 is installed with the two hurdles 301, thus connecting the two hurdles 301 into a complete long pole. This long pole design improves the accuracy of the hurdle height during hurdling. However, if the athlete fails to clear the hurdle 301 from above and instead steps on it, the pressure sensor 313 at the point of contact will detect a pressure value exceeding the safe pressure threshold. The controller 316 receives the pressure signal and reacts promptly, instantly de-energizing the electromagnet 304.After the power is cut off, the electromagnet 304 loses its magnetism, thus breaking its attraction to the iron block 305. When the athlete steps on it, the two hurdles 301 can quickly separate, disconnecting in the middle, preventing the athlete from tripping and thus protecting them. At this point, the flexible elastic band 309 connects the fixing block 306 and the adjusting slide rod 122, allowing the hurdles 301 to provide elastic cushioning when subjected to large forces. Furthermore, the hurdles 301 are made of a soft material, allowing them to bend when disconnected, further protecting the hurdler.

[0029] The wiring diagrams of the electromagnet 304, pressure sensor 313, and controller 316 in this invention are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the electromagnet 304, pressure sensor 313, and controller 316 will not be explained in detail.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
