Description

Technical Field

[0001] The invention relates to the technical field of high jump poles, in particular to an intelligent lifting and automatically resetting high jump pole. Background Art

[0002] High jump is a key event in track and field, and the high jump pole is frequently used in training and competition. Traditional high jump poles typically consist of a support pole, a bar support, and a crossbar. If an athlete fails to reach the set height, the crossbar is knocked off, requiring manual repositioning of the bar onto the bar support. This operation is cumbersome and inefficient, especially during high-intensity training or official competitions. Frequent manual repositioning not only wastes time but can also affect the rhythm of the competition and the athlete's performance.

[0003] Existing high jump poles are mostly fixed structures, lacking intelligent control methods and unable to achieve the automatic reset function of the crossbar. In addition, the height adjustment of traditional high jump poles relies on manual lifting and visual calibration, which has problems such as large errors and inconvenient adjustment. At the same time, due to the relatively bulky overall structure of the equipment, the assembly and disassembly process is complicated, and it is difficult to carry and transport, which makes it difficult to adapt to the needs of diverse training venues. Although some improved high jump poles have introduced electric lifting or remote control devices, most solutions still have defects such as complex structure, low reset accuracy, and poor portability, failing to fundamentally solve the problems of low automation and insufficient convenience. Therefore, a smart lifting and automatic reset high jump pole is needed to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent lifting and automatically resettable high jump pole, which has the advantages of automatic reset, precise height adjustment, modular detachability and strong portability, solving the problems of low efficiency, poor adjustment accuracy and inconvenience in carrying of traditional high jump poles requiring manual reset.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an intelligent lifting and automatically resettable high jump bar, comprising a base, a lower support rod, an upper support rod, a cross bar support and a cross bar body, the lower support rod being detachably mounted on the base, the upper support rod being detachably mounted on the lower support rod, the cross bar support being movably mounted on the front end surface of the upper support rod, the cross bar body being mounted on the cross bar support, the front end surface of the base being provided with a planetary gear drive assembly, the planetary gear drive assembly being provided with only a motor, a planetary gear reducer and a winding roller, the motor being mounted on the input shaft of the planetary gear reducer, the winding roller being mounted on the output shaft of the planetary gear reducer, the winding roller being provided with a traction rope fixedly connected to the cross bar body, and a controller and a remote control being provided between the two groups of the bases.

[0006] As a preferred intelligent lifting and automatically resettable high jump pole of the present invention, connectors are provided between the base and the lower support rod and between the upper support rod and the lower support rod, and the upper end faces and lower end faces of the connectors are provided with first docking columns, and the base, lower support rod and upper support rod are all provided with first docking grooves that are interference fit with the first docking columns.

[0007] As a preferred intelligent lifting and automatically resettable high jump pole of the present invention, the upper end face of the cross bar support is provided with a slider that cooperates with the slide groove, the lower support rod is provided with an electric telescopic rod that fits with the slider, and the side end face of the cross bar support is provided with a rotatably connected roller, and the roller is fitted with the side end face of the upper support rod.

[0008] As a preferred intelligent lifting and automatically resettable high jump pole of the present invention, the top of the upper support rod is provided with a top cover with an interference fit, the front end of the lower end face of the top cover is provided with a laser rangefinder, and the front end faces of the upper support rod and the lower support rod are provided with scale lines.

[0009] As a preferred embodiment of the intelligent lifting and automatically resettable high jump pole of the present invention, positioning grooves are provided on the left and right sides of the base, and slidingly connected counterweight columns are provided in the positioning grooves.

[0010] As a preferred embodiment of the intelligent lifting and automatically resettable high jump pole of the present invention, the upper end surface of the crossbar support is provided with a guide groove and a threading hole that cooperate with the traction rope.

[0011] As a preferred intelligent lifting and automatically resettable high jump pole of the present invention, the cross bar body includes a center rod and a head, and second docking columns are provided at the left and right ends of the center rod. The head is provided with a second docking groove that is interference-connected with the docking column, the side end face of the second docking column is provided with a winding groove, and the side wall of the second docking groove is provided with a wire threading groove.

[0012] As a preferred embodiment of the intelligent lifting and automatically resettable high jump pole of the present invention, the front end surface of the controller is provided with a display and an infrared receiver.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention solves the efficiency problem of the traditional high jump bar requiring manual resetting through the linkage structure of the motor-driven winding roller and the traction rope, combined with the intelligent control of the remote control and controller. When the crossbar body falls, the motor can quickly tighten the traction rope to accurately reset it to the crossbar support, and then automatically release the traction rope length to maintain the freedom of movement of the crossbar. Combined with the winding groove and guide groove structure at both ends of the crossbar body, it ensures that the traction rope always moves along the predetermined trajectory to avoid deviation or entanglement. This intelligent reset mechanism significantly improves the continuity of training or competition. At the same time, through the dual calibration of the laser rangefinder and the scale line, the accuracy of height adjustment and data visualization are achieved, solving the problem of traditional equipment relying on manual measurement and prone to errors.

[0015] 2. The present invention adopts a modular detachable structure and an optimized counterweight design, breaking through the contradiction between portability and stability of traditional high jump equipment. The interference fit connectors between the base and the support poles and the split crossbar body design enable the equipment to be quickly disassembled into a compact unit for easy transportation and storage; and the counterweight column slidingly connected in the positioning groove can enhance the support stability by adjusting the center of gravity and can be disassembled and carried. This structural system not only solves the problem that fixed equipment is difficult to move, but also avoids the defect of easy tipping of lightweight design, meeting the needs of use in multiple scenarios while ensuring competitive safety.

[0026] See also Figures 1-9 , an intelligent lifting and automatically reset high jump bar, comprising a base 1, a lower support rod 2, an upper support rod 3, a cross bar support 12 and a cross bar body 9, the lower support rod 2 is detachably mounted on the base 1, the upper support rod 3 is detachably mounted on the lower support rod 2, the cross bar support 12 is movably mounted on the front end surface of the upper support rod 3, the cross bar body 9 is mounted on the cross bar support 12, and a planetary gear drive assembly 6 is provided on the front end surface of the base 1, the planetary gear drive assembly 6 is provided with only a motor 601, a planetary gear reducer 602 and a winding roller 603, the motor 601 is mounted on the input shaft of the planetary gear reducer 602, the winding roller 603 is mounted on the output shaft of the planetary gear reducer 602, and the winding roller 603 is provided with a traction rope 13 fixedly connected to the cross bar body 9, and a controller 7 and a remote control 8 are provided between the two groups of bases 1.

[0027] After the high jump, the crossbar falls and the main body falls. The remote control 8 timely controls the motor 601 to drive the winding roller 603 to reel in the traction rope 13, so that the traction rope 13 pulls the crossbar main body 9 back to the crossbar support 12 in time, thereby achieving timely reset. After reset, the motor 601 rotates to provide a certain amount of traction rope 13 for the crossbar, so that it can fall after being knocked down, which is convenient for observation. The traction rope 13 is made of PE fishing line, which is strong and not easy to deform, ensuring the accuracy of each reset.

[0028] Furthermore, a connector 4 is provided between the base 1 and the lower support rod 2 and between the upper support rod 3 and the lower support rod 2. The upper end face and the lower end face of the connector 4 are provided with a first docking column 401. The base 1, the lower support rod 2 and the upper support rod 3 are all provided with a first docking groove 101 that is interference fit with the first docking column 401.

[0029] The interference fit assembly structure allows for quick assembly of the device without the need for external tools, and it is easy to store and carry after disassembly, improving the portability of the device.

[0030] Furthermore, the upper end face of the cross bar support 12 is provided with a slider 1201 that cooperates with the slide groove 301, and the lower support rod 2 is provided with an electric telescopic rod 11 that fits with the slider 1201. The side end face of the cross bar support 12 is provided with a rotatably connected roller 1202, and the roller 1202 is fitted with the side end face of the upper support rod 3.

[0031] The slider 1201 is driven up and down by the lifting of the electric telescopic rod 11, thereby adjusting the height of the cross bar body 9. By adding rollers 1202 to the side end surface of the cross bar support 12, the friction between the cross bar support 12 and the upper support rod 3 is reduced, making the sliding smoother and avoiding the cross bar support 12 from getting stuck.

[0032] Furthermore, a top cover 5 with an interference fit is provided on the top of the upper support rod 3 , a laser rangefinder 5 is provided on the front end of the lower end face of the top cover 5 , and scale lines 302 are provided on the front end faces of the upper support rod 3 and the lower support rod 2 .

[0034] Furthermore, positioning grooves 102 are provided on the left and right sides of the base 1 , and slidingly connected counterweight columns 10 are provided in the positioning grooves 102 .

[0035] The counterweight column 10 lowers the center of gravity of the device, enhances the stability of the device, and prevents the device from frequently tipping over. The sliding connection structure also allows the counterweight column 10 to be disassembled and carried.

[0036] Furthermore, the upper end surface of the crossbar support 12 is provided with a guide groove 1203 and a threading hole 1204 that cooperate with the traction rope 13.

[0037] The traction rope 13 is guided by the guide groove 1203 to prevent the traction rope 13 from running off the track and affecting the resetting effect of the cross bar.

[0038] Furthermore, the cross bar body 9 includes a center rod 901 and a head 902, and second docking columns 9011 are provided at the left and right ends of the center rod 901, and a second docking groove 9021 is provided on the head 902 for interference connection with the docking column, and a winding groove 9012 is provided on the side end face of the second docking column 9011, and a wire threading groove 9022 is provided on the side wall of the second docking groove 9021.

[0039] The interference fit structure of the head 902 and the center rod 901 facilitates the disassembly and assembly of the equipment. A winding groove 9012 is provided on the second docking column 9011 to facilitate the installation and positioning of the traction rope 13, thereby preventing the traction rope 13 from deviating from the cross bar body 9. The detachable cross bar body 9 structure reduces its total length, making it easier to store.

[0040] Furthermore, the front end of the controller 7 is provided with a display 701 and an infrared receiver 702 .

[0041] The infrared receiver 702 receives the infrared signal of the remote controller 8, and the crossbar body 9 is reset in time after it falls, and the display 701 displays the current height in real time.

[0042] When using this high jump pole, first assemble the base 1, the lower support rod 2, and the upper support rod 3 by interference fitting the first docking column 401 of the connector 4 with the first docking groove 101, then install the cross bar support 12 on the lower support rod 2 from top to bottom through the slider 1201, pass the traction rope 13 through the guide groove 1203 and the threading hole 1204 of the cross bar support 12, wind it around the winding groove 9012 on the second docking column 9011 of the center rod 901 of the cross bar body 9 and fix it, interference connect the center rod 901 of the cross bar body 9 with the head 902 using the second docking column 9011 and the second docking groove 9021, install the counterweight column 10 in the positioning groove 102 of the base 1 to enhance stability, interference connect the top cover 5 to the top of the upper support rod 3, ensure that the laser rangefinder 5 is installed normally, then place the two sets of bases 1 in the appropriate position, and use the infrared receiver 702 of the controller 7 Pair with the remote control 8, set the required high jump height on the display 701 of the controller 7, use the electric telescopic rod 11 to drive the crossbar support 12 to rise and fall, combine the data sent back by the laser rangefinder 5 and the scale lines 302 on the front end surfaces of the upper support bar 3 and the lower support bar 2, and correct the height of the crossbar body 9 to the set value in real time. When the athlete performs the high jump, if the crossbar body 9 is knocked down, immediately use the remote control 8 to control the motor 601 in the planetary gear drive assembly 6 to drive the planetary gear reducer 602 and the winding roller 603 to rewind the traction rope 13. The traction rope 13 pulls the crossbar body 9 back to the crossbar support 12 to achieve reset. After resetting, the motor 601 rotates to release a certain length of traction rope 13 to ensure that the crossbar body 9 can fall smoothly when it is knocked down next time, so as to observe the results. At the same time, the crossbar height can be adjusted through the remote control 8 or the controller 7 according to actual needs for subsequent training or competition.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
