[0025] Reference Figure 1-Figure 3, which is an embodiment of the utility model, provides a device for analyzing and assessing students' physical education performance, including a main unit 100, an adjustment unit 200 and a positioning unit 300.

[0026] The main unit 100 includes a base 101 and universal wheels 102 matched with the base 101. The universal wheels 102 are located at the four corners of the bottom of the base 101. An analysis column 103 is provided at the top of the base 101. The analysis column 103 is used to record the results for convenient analysis and assessment. The universal wheels 102 can move the device to a designated location.

[0027] The adjustment unit 200 includes a mounting frame 201 fixedly mounted on the top of the base 101, and slide grooves 206 are symmetrically provided on opposite surfaces of the inner cavity of the mounting frame 201, and screw rods 207 are fixedly mounted on the inner cavity of the slide grooves 206. Slide blocks 208 are threadedly connected to the outer surfaces of the two groups of screw rods 207, and the opposite surfaces of the slide blocks 208 are fixedly connected to the analysis column 103. Transmission wheels 204 are fixedly mounted on the tops of the two groups of screw rods 207, and a transmission belt 205 is sleeved on the outer surface of the transmission wheel 204. The two groups of transmission wheels 204 rotate, driving the screw rod 207 to start rotating. When the screw rod 207 starts to rotate, because the slide block 208 is threadedly connected to the screw rod 207, the slide block 208 can move up and down on the surface of the screw rod 207 when the slide groove 206 limits the screw rod 207, thereby driving the analysis column 103 to move up and down, which can adapt to people of different heights and improve the practicality of the device.

[0028] A mounting seat 202 is fixedly mounted on the top of the mounting frame 201 , a motor 203 is fixedly mounted on the bottom of the mounting seat 202 , and an output end of the motor 203 is fixedly connected to a transmission wheel 204 , and the transmission wheel 204 can be driven to rotate by the motor 203 .

[0029] The positioning unit 300 includes a threaded groove 304 symmetrically opened on one side of the base 101, the inner cavity of the threaded groove 304 is threadedly connected to a threaded rod 302, a knob 301 is fixedly installed on the top end of the threaded rod 302, and a counterweight 305 is fixedly installed on the bottom end of the threaded rod 302. The knob 301 is rotated to rotate the threaded rod 302. Because the threaded rod 302 and the threaded groove 304 are threadedly connected, the threaded rod 302 can drive the counterweight 305 to move downward and contact the ground, thereby completing the positioning of the device.

[0030] The bottom end of the base 101 is symmetrically provided with a receiving groove 303 , and the receiving groove 303 and the counterweight block 305 are slidably connected, so that the counterweight block 305 can be moved into the receiving groove 303 to be received.

[0031] The counterweight block 305 is a rectangular structure, and the bottom end of the counterweight block 305 is provided with anti-slip grooves to enhance the friction of the counterweight block 305 and improve the positioning effect of the counterweight block 305 .

[0032] Handles 104 are symmetrically fixedly mounted on both sides of the mounting frame 201 , and anti-skid rubber pads are fixedly mounted on the outer surfaces of the handles 104 . The device can be moved by pulling the handles 104 .

[0033] During use, the handle 104 is pulled, and the device is moved to the designated location with the cooperation of the universal wheel 102, and the knob 301 is rotated to rotate the threaded rod 302. Because the threaded rod 302 and the threaded groove 304 are threadedly connected, the threaded rod 302 can drive the counterweight 305 to move downward and contact the ground to complete the positioning of the device, and the motor 203 is started. The motor 203 drives the transmission wheel 204 to rotate. Under the action of the transmission belt 205, the two sets of transmission wheels 204 are driven to rotate synchronously. The two sets of transmission wheels 204 rotate and drive the screw rod 207 to start rotating. When the screw rod 207 starts to rotate, because the slider 208 is threadedly connected to the screw rod 207, the slider 208 can move up and down on the surface of the screw rod 207 when the slide groove 206 limits the screw rod 207, thereby driving the analysis column 103 to move up and down, which can adapt to people of different heights and improve the practicality of the device.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
