Description

Technical Field

[0001] This invention relates to the field of track and field training equipment technology, and in particular to a track and field training sensing timer with infrared ray sensing. Background Technology

[0002] Track and field training timing is a key aspect of sports training, especially in events such as sprinting and hurdles. Accurate timing data of athletes' reaction time, acceleration phase, and sprint phase are of great significance for developing training plans and evaluating athletic performance.

[0003] Traditional track and field training timing relies on manual timing or handheld electronic stopwatches for recording. This method is greatly affected by human reaction time, resulting in significant errors. It not only makes it difficult to guarantee the accuracy of the data, but also hinders scientific analysis. Summary of the Invention

[0004] The main objective of this invention is to provide an infrared ray sensing timer for track and field training, aiming to solve the problems mentioned in the background art.

[0005] To address the aforementioned problems, this invention proposes an infrared ray sensing track and field training timer, comprising a support base, in which support devices are rotatably mounted within circumferential mounting grooves. An adjusting rod is slidably disposed in the middle of the support base, and an outer rod is rotatably disposed at a circumferential interval at the bottom end of the adjusting rod. An inner rod is slidably disposed on the inner wall of the outer rod, and the other end of the inner rod is rotatably connected to one side of the bottom end of the support device. A rotating shaft is fixedly disposed at the top end of the adjusting rod, and a mounting platform is rotatably disposed at the top end of the rotating shaft. A testing device is inserted and mounted at the top end of the mounting platform.

[0006] In one embodiment, the support device includes a support rod, a first connector is fixedly provided at the top end of the support rod, a second connector is fixedly provided at the bottom end of the support rod, guide rods are fixedly provided on both sides of the support rod, a slide block is slidably installed on the support rod and the guide rod, a limit device is slidably installed in the internal mounting groove of the slide block, a hinge joint is fixedly provided on one side of the slide block, and a support leg is fixedly provided at the bottom end of the second connector.

[0007] In one embodiment, the other end of each inner rod is rotatably connected to the inner wall of a hinge joint on one side of the slide.

[0008] In one embodiment, the limiting device includes a buckle, the shape of which matches the limiting groove on one side of the support rod, a U-shaped push rod is fixedly provided on one side of the buckle, and a spring is fixedly provided in the middle of the other side of the buckle.

[0009] In one embodiment, a portion of the push rod extends beyond the slide block to facilitate pressing it into a mounting groove within the slide block.

[0010] In one embodiment, the testing device includes a housing, an infrared sensor is fixedly disposed on one side of the housing, and a display screen is fixedly disposed on the other side of the housing.

[0011] In one embodiment, a limiting block is fixedly provided at the bottom of the testing device, and the limiting block is slidably inserted into a dovetail groove on one side of the mounting platform.

[0012] Beneficial effects: This invention provides an infrared-sensing track and field training timer. Through the coordinated arrangement of a support device, adjusting rod, and mounting platform, the height and angle of the testing device can be flexibly adjusted to adapt to the needs of different venues and training events. The adjusting rod slides up and down within the support base, raising and lowering the mounting platform to position the testing device at an appropriate height. Simultaneously, the telescopic structure of the outer and inner rods forms a stable triangular support structure when the support device is extended, improving overall stability. A limiting device automatically limits the sliding state of the support device, ensuring that the equipment does not shake after adjustment and can stably maintain the infrared emission direction, guaranteeing detection accuracy and safety.

[0013] By using infrared sensors in conjunction with a display screen, automated timing and real-time data feedback are achieved, avoiding errors and delays inherent in manual timing and improving the accuracy of training data. The infrared sensor automatically triggers a timing signal the moment an athlete passes by, and the display screen instantly shows the time information. At the same time, the testing device is equipped with a wireless transmission module, which can upload the test results to a mobile phone or computer in real time, making it convenient for coaches or athletes to compare and analyze the data and develop training plans.

[0014] The installation structure, which combines a limiting block with a dovetail groove, allows for quick connection and disassembly between the testing device and the mounting platform. It is easy to disassemble and reduce the size during transportation or storage. The limiting device, consisting of a buckle, a push rod, and a limiting plate, allows users to quickly lock or release the limiting position during adjustment or folding. The entire device can be quickly set up and adjusted, making it particularly suitable for short-term deployment before track and field competitions and multi-point setup in training environments, significantly improving efficiency and convenience.

[0018] 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 a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] To achieve the above-mentioned objectives of the invention, such as Figure 1-4As shown, this invention provides an infrared ray sensing track and field training timer, including a support base 1. The support base 1 is circular, with three mounting slots spaced apart around its circumference. A support device 4 is rotatably mounted in each mounting slot. An adjusting rod 2 is slidably disposed in the middle of the support base 1. A rotating shaft 6 is fixedly disposed at the top of the adjusting rod 2. A mounting platform 7 is rotatably disposed at the top of the rotating shaft 6. A testing device 3 is slidably inserted into the top surface of the mounting platform 7. A limiting block 8 is fixedly disposed on one side of the bottom end of the testing device 3. The shape of the limiting block 8 matches the dovetail groove opened on one side of the mounting platform 7. After the limiting block 8 is inserted, a fixing bolt can be inserted into the threaded opening on the bottom surface of the dovetail groove to prevent the testing device 3 from shaking or falling off during use. A circular base is provided at the bottom end of the adjusting rod 2. A hinge seat is spaced apart around the circumference of the base. An outer rod 9 is rotatably disposed in each hinge seat. Multiple limiting grooves are spaced apart on one side of the outer rod 9. An inner rod 91 is slidably installed on the inner wall of the outer rod 9. A limiting head is provided on one side of the inner rod 91 located on the inner wall of the outer rod 9. When the inner rod 91 slides to one side of the inner wall of the outer rod 9, it can be automatically locked by the limiting head. When it slides to the other side, the limiting head needs to be manually pressed down to release the lock. The top of the other side of each inner rod 91 is rotatably connected to the lower side of the rod of the support device 4.

[0020] like Figure 1-2 As shown, the testing device 3 includes a housing 31. An infrared sensor 33 is fixedly installed on one side of the housing 31. A charging connector, a line interface, and a power switch are installed on the side opposite the infrared sensor 33. A battery is fixedly installed inside the housing 31. A display screen 32 is fixedly installed on the other side of the housing 31. During use, the testing device 3 is first inserted into the dovetail groove of the mounting platform 7 through the limiting block 8 at the bottom, and fixed by inserting a fixing bolt into the threaded hole to limit and fix it to prevent movement or falling off during use. The infrared sensor 33 continuously emits infrared rays during operation to accurately detect when athletes pass by, thereby avoiding errors in manual timing. When the infrared sensor 33 is triggered, the display screen 32 can display and record time information in real time. The testing device 3 can also upload data to the mobile phone in real time through the internal network chip for easy data recording and comparison. This device can be set up at intervals in the middle of the track, such as at the 30-meter, 60-meter, and finish lines in a 100-meter race, to detect athletes' segmented speed and explosive endurance, which is helpful for developing subsequent training plans.

[0021] like Figure 1-3As shown, the support device 4 includes a support rod 41. Multiple arc-shaped limiting grooves are spaced apart on one side of the support rod 41. A first connector 43 is fixedly installed at the top end of the support rod 41, and a second connector 45 is fixedly installed at the bottom end. Guide rods 42 are fixedly installed on both sides of the support rod 41. Slide seats 44 are slidably installed at the lower ends of both the support rod 41 and the guide rods 42. A hinge joint 47 is fixedly installed on one side of the slide seat 44. The top end of one side of an inner rod 91 is rotatably connected to the hinge joint 47. Through the pulling action of the inner rod 91, the support device 4 can be prevented from opening due to excessive force. The opening angle of the support device 41 causes the center of gravity to shift. The inner wall of the slide 44 is fixedly provided with a limiting device 5, which is used to embed into the arc-shaped limiting groove of the support rod 41 for positioning and limiting. The top surface of the slide 44 is provided with positioning holes spaced apart, into which the limiting plate 10 can be inserted. After pressing the limiting device 5 to unlock it, the limiting plate 10 is inserted to prevent the limiting device 5 from rebounding, so that the support rod 41 remains in a sliding state, which facilitates the adjustment of the opening angle of the support device 4. The first connector 43 is rotatably installed in the circumferential mounting groove of the support base 1, and the bottom center of the second connector 45 is fixedly provided with a support leg 46.

[0022] like Figure 3-5 As shown, the limiting device 5 includes a buckle 51, which is semi-circular in shape and matches the arc-shaped limiting groove of the support rod 41. A push rod 52 is fixedly installed on one side of the buckle 51. The push rod 52 is U-shaped and its two ends are fixedly connected to the two extended ends of the buckle 51. Its main body is exposed outside the mounting groove of the slide block 44 for easy manual pressing. A spring 53 is fixedly installed in the middle of the other side of the buckle 51. The other end of the spring 53 is fixedly connected to one side of the inner wall of the slide block 44. When the adjusting rod 2 moves up and down... At the same time, the outer rod 9 can drive the slide 44 to slide on the support rod 41 and the guide rod 42, while the adjusting rod 2 slides up and down in the middle of the support base 1, lifting the mounting platform 7 and the testing device 3, thereby adjusting the height of the testing device 3. During this process, the push rod 52 can be pressed to make the buckle 51 disengage from the limiting groove of the support rod 41, and at the same time, the limiting plate 10 is inserted into the positioning hole at the top of the slide 44 to prevent the limiting device 5 from rebounding. After the adjustment is completed, the limiting plate 10 is removed, and the spring 53 pushes the buckle 51 to automatically reset and lock.

[0023] like Figure 2-6 As shown, during the height adjustment process, the outer rod 9 can automatically rotate at the bottom to adapt to angle changes, and the inner rod 91 can automatically slide out and engage in the limit position according to the spacing to achieve stable support. When retracting, the limit position needs to be manually released to prevent automatic retraction from causing tipping. By sliding up and down the inner wall of the support base 1, the adjustment rod 2 can achieve precise adjustment of the height of the rotating shaft 6 and the mounting platform 7, thereby enabling the rapid deployment and flexible adjustment of the testing device 3 under different site conditions.

[0024] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
