Technical Field
[0001] The utility model relates to the technical field of sports equipment, in particular to a sit-up body measurement integrated device for counting sit-ups. Background Art
[0002] Sit-ups are a common item in physical fitness tests, mainly used to test arm strength and waist endurance. Existing sit-up tests are generally completed manually and with a sit-up tester. Common sit-up test equipment includes: a sit-up board, a low-position sensor, and a high-position sensor or a camera. When the sit-up tester is tested based on a camera, the subject lies on his back on the mat, with his legs slightly apart, his feet fixed on the instrument on the mat, his knees bent at an angle of about 90 degrees, and his two fingers crossed and attached to the back of his head. The entire process of sit-ups is recorded by a camera, and based on the images recorded by the camera, the number of sit-ups of the tester is standardized and counted using the system.
[0003] However, since the tester or examinee has a large range of body movements during sit-ups, the sit-up board is often easy to slide during the sit-up process, causing the camera shooting angle and position to change, resulting in counting failure or inaccuracy, affecting the tester or examinee's recorded score. Therefore, a sit-up counting device with better firmness and stability is needed, which is easy to fix with the sit-up board at the same time to avoid changes in the shooting position. To this end, we designed a sit-up body measurement device for sit-up counting to solve the above problems. Utility Model Content

DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] This embodiment proposes a sit-up physical test integrated device for counting sit-ups. The intelligence of the device is mainly reflected in the collection of images of the entire sit-up process of the tester, and the sit-up determination and counting system is used to analyze and determine the collected images, and the number of sit-ups done by the tester is counted. The collection mechanism 20 of this embodiment adopts a camera for counting and capturing the sit-up movement of the tester. The camera is connected to a processor through a high-speed communication data line. The processor adopts a desktop computer, a microprocessor, etc., which is convenient for counting the sit-ups of the tester. The focus of this embodiment is how to enhance the stability of the device and ensure the continuity and continuity of image acquisition.
[0023] like Figure 1 As shown, the device mainly includes a lying frame 10, a pad 11 and a foot frame 12 for the tester to lie on his back. The pad 11 is laid on the lying frame 10, and the foot frame 12 is fixedly installed at one end of the lying frame 10. The foot frame 12 is a "T"-shaped structure. In order to improve the comfort of the tester, soft sponge covers 13 are provided on both ends of the horizontal rod of the foot frame 12.
[0024] Fixed brackets 21 are fixedly installed on both sides of the middle of the lying frame 10, and collection mechanisms 20 for collecting motion images of the tester doing sit-ups are fixed on both sides of the lying frame 10. The collection mechanism 20 is installed on the lying frame 10 through the fixed brackets 21. Specifically, the collection mechanism 20 for collecting the test sit-up images is set at the upper end of the fixed bracket 21, so that the collection mechanism 20 is fixed at the upper side of the two sides of the lying frame 10. The outer cover of the collection mechanism 20 is provided with a protective cover 25. The collection mechanism 20 establishes a transmission connection with the terminal equipment of the counting system through the data line 22. The lower end of the protective cover 25 is fixedly installed on the rod body of the fixed bracket 21. The data line 22 is arranged and fixed along the side of the fixed bracket 21. The lower end of the fixed bracket 21 is fixedly connected to the frame body of the lying frame 10; the fixed bracket 21 is an "L"-shaped bracket structure. Specifically, the fixed bracket 21 is composed of two "L"-shaped single rods, and a plurality of transverse fixed rods 211 are arranged between the two single rods. The lower end of the lying frame 10 and the fixing bracket 21 is threadedly connected with a base 16 for adjusting the height of the device. In order to enhance the anti-skid property of the base 16, an anti-skid rubber pad is provided at the bottom of the base 16 in contact with the ground. Finally, a flexible soft pad 14 is laid on the upper surface of the pad 11 to contact the tester's body.
[0025] like Figure 2 As shown, the lie-flat frame 10 is a rectangular structure, and a plurality of reinforcing rods 15 are fixedly connected between the rod bodies on both sides of the lie-flat frame 10 .
[0026] In order to standardize the wiring and improve the overall simplicity and beauty of the device, the wiring of the data line 22 is optimized in this example. After one end of the data line 22 is fixed along the side of the fixed bracket 21, it passes through the frame of the lying frame 10, is further laid along the inner side of the frame of the lying frame 10, and passes through the reinforcing rod 15, and finally is connected to the terminal 26 set on the end frame of the lying frame 10. The terminal device of the counting system is directly connected to the terminal 26, so that the signal data transmission between the terminal device of the counting system and the collection mechanism 20 can be realized.
[0027] Reference Figure 3 As the unique feature of the utility model, in order to meet the needs of picture acquisition, while ensuring that the acquisition mechanism 20 is installed stably and firmly, the horizontal distance between the acquisition mechanism 20 and the tester can be flexibly adjusted. In the scheme of this embodiment, the fixed bracket 21 abandons the method of direct fixed connection with the frame body of the lying flat frame 10. The horizontal setting of the fixed bracket 21 and the lying flat frame 10 is a cross bar 23. The specific connection method is as follows: the cross bar 23 connecting the fixed bracket 21 and the lying flat frame 10 passes through the through hole 17 on the frame body of the lying flat frame 10 and is inserted into the lower part of the pad 11. The lower part of the through hole 17 is provided with a threaded hole 18 for fixing the cross bar 23. The fastening bolt 19 is threadedly connected with the threaded hole 18. The end of the fastening bolt 19 is against the lower end surface of the cross bar 23. The extrusion force of the fastening bolt 19 on the cross bar 23 fixes and constrains the movement of the cross bar 23. Then, with the support and anti-slip effect of the base 16 at the lower part of the cross bar 23, the cross bar 23 and the lying flat frame 10 form a stable structure.
[0028] like Figure 4 As shown, further, in order to facilitate the flexible adjustment of the vertical height of the acquisition mechanism 20 and expand the image acquisition and recognition range of the acquisition mechanism 20. A vertical rod 24 is set in the vertical direction of the fixed bracket 21. The fixed bracket 21 vertically supports and fixes the vertical rod 24 of the acquisition mechanism 20, including a square sleeve 241 and a square insert 242. The bottom of the square sleeve 241 is fixed to the end of the cross bar 23, and the upper end of the square insert 242 is fixedly installed with the acquisition mechanism 20. A plurality of limiting holes 243 are opened on the square sleeve 241 and the square insert 242 at the same interval. After the square insert 242 is inserted into the square sleeve 241, the fixing pin 244 is inserted into the limiting hole 243 of the square sleeve 241 corresponding to the height of the square insert 242. According to the use requirements, after adjusting the height of the acquisition mechanism 20, the square insert 242 is limited and fixed in the square sleeve 241 by the fixing pin 244.
[0029] Usage process: When the utility model is used, according to conventional usage habits, the lying frame 10 carrying the pad 11 is fixed to the fixed bracket 21 supporting the fixed collection mechanism 20, and the position of the collection mechanism 20 is fixed at the upper left and right sides of the pad 11, so that the lying frame 10, the pad 11, the fixed bracket 21 and the collection mechanism 20 are connected as a fixed whole, while ensuring the overall stability of the device, the collection mechanism 20 is kept consistent with the test collection position and angle, which greatly improves the collection accuracy and ensures the accuracy of the count during the sit-up movement of the tester. Even if the sit-up lying frame 10 moves due to the tester's excessive movement during the sit-up movement, the collection mechanism 20 can be kept moving with the sit-up lying frame 10 at the same time, ensuring that the collection mechanism 20 collects the tester's perspective and always covers the tester's motion range, effectively avoiding the change of the collection mechanism 20 and the tester's collection position caused by the movement of the sit-up lying frame 10, resulting in an incomplete collection picture.
[0030] In order to adapt to the use of testers of different grades (different age groups and different heights), during the use of the utility model, the collection mechanism 20 is adjusted to a position obliquely above the tester according to the body occupation area of the tester; on the one hand, the cross bar 23 passes through the through hole 17 on the frame body of the lying frame 10 and is inserted into the lower part of the pad 11, and then the fastening bolt 19 is inserted into the threaded hole 18, and then rotated so that the end of the fastening bolt 19 is against the lower end surface of the cross bar 23, and the movement of the cross bar 23 is fixed and constrained by the squeezing force of the fastening bolt 19 on the cross bar 23, that is, the distance between the collection mechanism 20 and the tester is adjusted horizontally, and the cross bar 23 on the fixed bracket 21 is aligned with the lying frame. 10 forms a stable structure; on the other hand, the square insert 242 of the fixed collection mechanism 20 is inserted into the square sleeve 241, and after the height of the collection mechanism 20 is adjusted, the fixing pin 244 is inserted into the limiting hole 243 of the square sleeve 241 corresponding to the height of the square insert 242, and the square insert 242 and the square sleeve 241 are fixed by the fixing pin 244, and the horizontal and vertical distances between the collection mechanism 20 and the tester are flexibly adjusted. According to the use requirements, the collection viewing angle range of the collection mechanism 20 can be reduced or expanded to meet the use requirements of testers of all ages, which greatly expands the application scenarios of the device in the field of sit-up testing.
[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
