Description

Technical Field

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

[0002] Hurdles are a type of equipment used in hurdling competitions and training. Hurdling is a technically demanding sprint event in which participants must clear hurdles of a specified height and number over a certain distance. It is a type of track and field event in athletics.

[0003] The existing hurdles have certain drawbacks. Because the hurdles are supported by two posts, and the posts can be independently adjusted in height, the independent adjustment can cause the hurdles to be unstable in height, resulting in an imbalance. Secondly, the existing hurdles are not easy to disassemble and assemble. Finally, the existing hurdles are fixed in place, which can easily cause athletes to trip during training, and do not provide better safety, thus having a certain impact. Utility Model Content

[0004] To solve the above problems, this utility model provides a hurdle for track and field training, which is achieved through the following technical solution.

[0005] A hurdle for track and field training includes a base, with two fixed tubes fixedly connected to the top of the base. Each of the two fixed tubes is fixedly connected to a column. A transmission tube is connected through one end of each column. A transmission box is fixedly connected to the opposite ends of the two transmission tubes. A telescopic rod is movably connected to the other end of each column. A support frame is fixedly connected to one end of the telescopic rod. A hurdle is connected through the two support frames.

[0006] Furthermore, a fixing rod is fixedly connected to one side of the support frame, and a clamping plate is rotatably connected to the fixing rod. A spring is fixedly connected between the clamping plate and the support frame, and the spring is sleeved on the fixing rod. A slot is provided at the bottom of the support frame to fit into the clamping plate.

[0007] Furthermore, the hurdle is inserted between the support frame and the clamping plate.

[0008] Furthermore, a lead screw is rotatably connected inside the column, and a lifting block is fixedly connected to one end of the telescopic rod extending into the column. One end of the lead screw passes through the lifting block and is threadedly engaged with it. The lifting block slides with a sliding groove inside the column via a slider.

[0009] Furthermore, a transmission rod is rotatably connected to the transmission box, and a second helical gear is fixedly connected to one end of the transmission rod extending into the column. A first helical gear is fixedly connected to the other end of the lead screw, and the first helical gear meshes with the second helical gear. A servo motor is fixedly connected to the transmission box, and a worm gear is fixedly connected to the output shaft of the servo motor. A worm wheel fixed on the transmission rod meshes with the worm gear.

[0010] Furthermore, a fastening knob is provided on the fixing tube, and the column is fixedly connected to the fixing tube through the fastening knob.

[0011] The beneficial effects of this utility model are that, during the operation of this device, the hurdle can be inserted between two support frames, and the rotating clamping plate on the support frame can press against the hurdle. Since the clamping plate and the support frame are connected by a spring, the energy-storing spring can pull the clamping plate to press against the hurdle, thereby positioning the hurdle on the support frame. When the hurdle is subjected to external force, it can automatically detach, avoiding obstruction and tripping during hurdle training, and improving the safety of training.

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, the present invention has the following specific embodiments.

[0025] Example:

[0026] A hurdle for track and field training includes a base 1. Two fixed pipes 11 are fixedly connected to the top of the base 1. Each fixed pipe 11 is fixedly connected to a column 2. A transmission pipe 22 is connected through one end of each column 2. A transmission box 4 is fixedly connected to the opposite ends of the two transmission pipes 22. A telescopic rod 21 is movably connected to the other end of the column 2. A support frame 5 is fixedly connected to one end of the telescopic rod 21. A hurdle 3 is connected through the two support frames 5.

[0027] By adopting the above technical solution, when using the device, the base 1 can be placed on the ground, the column 2 can be fixedly installed on the base 1, the telescopic rod 21 can be raised and lowered on the column 2 to facilitate height adjustment, and the hurdle 3 can be inserted and fixed on the two support frames 5 to facilitate height adjustment and disassembly. The support frame 5 can squeeze and position the hurdle 3, and can automatically detach under external force. The structure is reasonable, which can improve the safety of training and facilitate disassembly and transportation.

[0028] Specifically, a fixing rod 51 is fixedly connected to one side of the support frame 5, and a clamping plate 52 is rotatably connected to the fixing rod 51. A spring 53 is fixedly connected between the clamping plate 52 and the support frame 5, and the spring 53 is sleeved on the fixing rod 51. A groove is provided at the bottom of the support frame 5 to fit into the clamping plate 52.

[0029] The hurdle 3 is inserted between the support frame 5 and the clamping plate 52.

[0030] By adopting the above technical solution, the hurdle 3 can be inserted between two support frames 5. The rotating clamping plate 52 on the support frame 5 can press against the hurdle 3. Since the clamping plate 52 and the support frame 5 are connected by a spring 53, the energy-storing spring 53 can pull the clamping plate 52 to press against the hurdle 3, thereby positioning the hurdle 3 on the support frame 5. When the hurdle 3 is subjected to external force, it can automatically fall off, avoiding obstruction and tripping during hurdle training, and improving the safety of training.

[0031] Specifically, the column 2 is rotatably connected to a screw rod 24, and the end of the telescopic rod 21 extending into the column 2 is fixedly connected to a lifting block 23. One end of the screw rod 24 passes through the lifting block 23 and is threadedly engaged with it. The lifting block 23 is slidably engaged with the sliding groove inside the column 2 through a slider.

[0032] A transmission rod 42 is rotatably connected to the transmission box 4. One end of the transmission rod 42 extending into the column 2 is fixedly connected to a second helical gear 422. The other end of the lead screw 24 is fixedly connected to a first helical gear 25, and the first helical gear 25 meshes with the second helical gear 422. A servo motor 41 is fixedly connected to the transmission box 4. The output shaft of the servo motor 41 is fixedly connected to a worm gear 411. The worm wheel 421 fixed on the transmission rod 42 meshes with the worm gear 411.

[0033] By adopting the above technical solution, the hurdle 3 connected to the telescopic rod 21 can be adjusted to rise and fall stably. Specifically, by turning on the servo motor 41, the worm gear 411 can be driven to rotate. The worm gear 411 drives the connected transmission rod 42 to rotate through the worm wheel 421. The transmission rod 42 drives the second helical gear 422 to rotate. The second helical gear 422 drives the meshing first helical gear 25 to rotate. The first helical gear 25 drives the lead screw 24 to rotate. The lead screw 24 drives the threaded lifting block 23 to rise and fall. The lifting block 23 drives the connected telescopic rod 21 to rise and fall on the column 2, thereby causing the telescopic rod 21 to push the hurdle 3 erected on the support frame 5 to rise and fall.

[0034] Specifically, a fastening knob 12 is provided on the fixing tube 11, and the column 2 is fixedly connected to the fixing tube 11 through the fastening knob 12.

[0035] By adopting the above technical solution, the column 2 and the base 1 can be fixed together, and it is also easy to disassemble and assemble.
