DETAILED DESCRIPTION

[0037] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0038] like Figure 1-10 As shown, the vertical body measuring ruler for sports and health includes:

[0039] The measuring assembly 100 is composed of a stand 101, a base 102 and a top plate 106. The two ends of the stand 101 are fixedly connected to the base 102 and one end of the top plate 106 respectively. A square opening is opened in the middle of the stand 101, and a lifting assembly 400 is arranged inside the opening.

[0040] An adjustment component 200, wherein the adjustment component 200 is slidably connected to the inside of a slide slot 304 provided on the side wall of the stand 101, and a telescopic mechanism is movably connected to the bottom of the adjustment component 200, and the number of the telescopic mechanisms is two, and the two telescopic mechanisms are symmetrically arranged on both sides of the stand 101 for measuring the arm length of students;

[0041] The driving component 300 is embedded in the embedding grooves 302 provided on both sides of the opening, and the two ends of the stand 101 located outside the embedding grooves 302 are provided with sliding grooves 304. The driving component 300 is transmission-connected with the lifting component 400, and the lifting component 400 is provided with a winding mechanism.

[0042] A weight scale 103 is embedded and installed on the surface of the base 102, and a standing area 104 is provided on the surface of the base 102 located on one side of the weight scale 103, and the standing area 104 is located on one side of the stand 101, and a display screen 105 is fixedly connected to the top side wall of the stand 101, and a first electric push rod 107 is fixedly installed on the top of the top plate 106, and the telescopic end of the first electric push rod 107 is fixedly connected to the moving plate 108 through a pressure sensor, and an infrared rangefinder 109 is fixedly connected to the surface of the moving plate 108, and the infrared rangefinder 109 is distributed correspondingly to the top plate 106, and the moving plate 108 is distributed correspondingly to the standing area 104.

[0043] In the present technical solution, a weight scale 103 is added to the base 102 to realize weight measurement. After the measurement is completed, the base 102 stays at the standing area 104, and the height, wide shoulder width, waist width and hip width, arm length, chest circumference, waist circumference and hip circumference and other data are measured in the standing area 104, and the infrared rangefinder 109 is used to realize accurate measurement of height. The first electric push rod 107 is used to drive the moving plate 108 to contact the student's head. At this time, the infrared rangefinder 109 measures the height to improve the accuracy of the data, and displays the measured value on the display screen 105.

[0044] The adjustment assembly 200 consists of a slider 201 and a slide plate 202. The slider 201 has a T-shaped cross-section and is slidably engaged with the inside of a slide groove 304. A scale line is provided on the surface of the stand 101 on one side of the slide groove 304. The slider 201 is fixedly connected to the slide plate 202, and the slide plate 202 slides in contact with the surface of the stand 101. The slide plate 202 is fixedly connected to a sleeve plate 203 with a U-shaped structure, and a translation plate 204 is movably sleeved inside the sleeve plate 203. One end of the translation plate 204 is fixedly connected to a side plate 205. A first locking mechanism is provided on one side of the top of the side plate 205, and a second locking mechanism is provided on the bottom of the sleeve plate 203. The other side of the side plate 205 is fixedly connected to a fitting plate 206 for contact with the student's body.

[0045] In the present technical solution, the slide groove 304 is set to enable the movement of the slider 201, and the stable movement is achieved through the cooperation of the slide plate 202. The position of the slide plate 202 is determined by the set scale lines, which facilitates the measurement of the height of the corresponding part during the measurement of the width. The sleeve plate 203 can achieve stable movement of the translation plate 204, so that the translation plate 204 drives the side plates 205 to contact the shoulders, waist or both sides of the hips. At this time, the width is determined by the scale lines on the translation plate 204.

[0046] The first locking mechanism is composed of a limit plate 207 and a latch 208. The limit plate 207 is fixedly connected to the top of the side plate 205. The limit plate 207 has a U-shaped cross section and a latch 208 is movably inserted inside. The latch 208 is an L-shaped structure and contacts the surface of the stand 101. The stand 101 is provided with uniformly distributed latch teeth 305 on one side close to the slide groove 304. After the latch 208 is translated, the latch 208 is engaged with the latch teeth 305. One end of the latch 208 is connected to the limit plate 207 through a first spring 209. The second locking mechanism is composed of a rotating rod 211 and a push rod 210. The rotating rod 211 has an L-shaped cross section and contacts the sleeve The bottom of the plate 203 is rotatably connected, and the rotating rod 211 extends to the inside of the slide groove 304 and is arranged on one side of the latch tooth 305. When the rotating rod 211 rotates, the horizontal end of the bottom of the rotating rod 211 is engaged with the inside of the latch tooth 305, and the rotating rod 211 is connected to the bottom surface of the sleeve plate 203 through the inclined second spring 212. The push rod 210 is fixedly connected to the bottom of the side plate 205, and the push rod 210 is correspondingly arranged on one side of the rotating rod 211. The side plate 205 and the sleeve plate 203 are both fixedly connected to the magnet 214. The two magnets 214 correspond to each other and the magnetic poles of adjacent surfaces are the same. The side wall of the sleeve plate 203 is threadedly connected to the knob 213, and the knob 213 contacts the side wall of the translation plate 204.

[0047] In the technical solution, during the movement of the slider 201 and the slide plate 202, before the movement, the magnetic poles of the two magnets 214 repel each other so that the latch 208 is inserted into the inside of the latch tooth 305. At this time, the latch 208 restricts the slider 201 from falling, and the water-passing rod 210 presses against the rotating rod 211 so that it is located inside the slide groove 304 and does not contact the latch tooth 305. When it is necessary to move, the side plate 205 is pushed to both sides, and the magnetic force of the magnet 214 is overcome to make the side plate 205 translate outward, and the side plate 205 drives the latch 208 is separated from the latch teeth 305. At this time, the slider 201 is not restricted and keeps the thrust of the side plate 205 while moving the adjustment assembly 200 up and down, thereby achieving height adjustment. When the adjustment is completed, it is released, and the latch 208 is re-engaged in the latch teeth 305 to achieve limit. When it is necessary to measure the width, before moving the side plate 205 toward the center, the latch 208 is pulled while holding the side plate 205, so that the latch 208 is separated from the latch teeth 305 and then the side plate 205 is moved. The side plate 205 drives the translation plate 204 to move in a certain direction. After the sleeve plate 203 moves stably, the push rod 210 is separated from the rotating rod 211, and the elasticity of the second spring 212 pushes the rotating rod 211 to rotate and move it to the inside of the latch 305. At this time, although the latch 208 no longer limits the slider 201, when the rotating rod 211 holds the slider 201 to ensure a constant position during the movement, the side plate 205 drives the fitting plate 206 to contact one side of the student's body, and the moving length is determined by the scale line on the translation plate 204, thereby determining the width of the student. After use, the side plate 205 is reset so that the elasticity of the first spring 209 drives the pin 208 to be re-inserted into the tooth 305. At this time, the push rod 210 pushes the rotating rod 211 to move from the tooth 305 to the inside of the slide groove 304. At the same time, the magnets 214 correspond to each other. After hearing the click sound when the pin 208 is suddenly inserted into the tooth 305, it stops moving. When the height needs to be adjusted, continue to push the side plate 205, and the pin 208 will move horizontally away from the tooth 305 to adjust the height, thereby improving the convenience of use.

[0048] The telescopic mechanism includes a rocker arm 215, which is rotatably connected to the bottom of the side plate 205. A guide sleeve 216 is fixedly connected to the side wall of the rocker arm 215. A pull rod 218 is inserted and engaged inside the guide sleeve 216, and the inside of the guide sleeve 216 is connected to the pull rod 218 through a third spring 217. The pull rod 218 is fitted and connected to the surface of the rocker arm 215, and a scale is provided on the surface of the pull rod 218.

[0049] In the present technical solution, after the position of the adjustment component 200 is adjusted, the bottom of the side panel 205 is made to correspond to the position of the shoulder joint. When measuring, the arms are spread out so that the arms and the rocker arm 215 fit each other, and the fingers are used to support the end of the pull rod 218. The third spring 217 is used to reset the pull rod 218 after it is moved out of the guide sleeve 216, so as to facilitate the measurement operation of different students.

[0050] The drive assembly 300 includes a lead screw 301, which is rotatably connected to the inside of the stand 101. There are two lead screws 301, both of which are located inside the embedded groove 302. The top of one lead screw 301 is fixedly connected to the output end of the drive motor 303, and the drive motor 303 is fixedly installed in the stand 101 at the top of the embedded groove 302. The two lead screws 301 are threadedly connected to the lifting assembly 400, and the bottoms of the two lead screws 301 are fixedly connected to the pulleys, and the pulleys are connected by a belt. Transmission connection; the lifting assembly 400 is composed of a cross bar 401 and a cross plate 402, both ends of the cross bar 401 are threadedly connected to the lead screw 301, the middle part of the cross bar 401 is fixedly connected to one end of the cross plate 402, and the other end of the cross plate 402 is fixedly connected to the cross bar 401 through an inclined reinforcement rod, and an L-shaped guide rail 403 is fixedly connected to the surface of the cross plate 402, and the guide rail 403 is two in number and symmetrically arranged on both sides of the cross plate 402, and a winding mechanism is slidably connected inside the guide rail 403.

[0051] In the present technical solution, when measuring the student's three dimensions, the driving motor 303 is started to drive the lead screw 301 to rotate in the embedding groove 302, and the pulley and belt at the bottom of the lead screw 301 cooperate to achieve synchronous rotation, thereby driving the cross bar 401 to slide in the embedding groove 302, and the cross bar 401 drives the cross plate 402 to rise and fall to achieve height adjustment of the lifting assembly 400. When the cross plate 402 moves to the appropriate position, the second electric push rod 404 is started to move the electric telescopic plate 405 inside the guide rail 403, thereby driving the winding mechanism to move to the front of the body, so as to facilitate adjustment according to the student's standing position, while ensuring that the winding mechanism can rotate smoothly from the stand 101.

[0052] The winding mechanism is composed of a telescopic plate 405, the cross section of which is a T-shaped structure and is slidably connected to the inside of the guide rail 403, one side of the transverse plate 402 is fixedly connected to the second electric push rod 404, and the telescopic end of the second electric push rod 404 is fixedly connected to the telescopic plate 405, and a stepper motor 406 is fixedly installed at the end of the telescopic plate 405 located on one side of the transverse plate 402, and the output end of the stepper motor 406 is fixedly connected to the rotating shaft 407, and the surface of the rotating shaft 407 is fixedly connected to an arc rod 408, and the arc rod 408 is located inside the opening opened by the stand 101, and the end of the arc rod 408 is fixedly connected to two limit columns 409; the horizontal plate 402 is an L-shaped structure, and a connecting seat 410 is fixedly installed on the outer side of the horizontal plate 402, the top of the connecting seat 410 is rotatably connected to the reel 412, and the reel 412 is connected to the top surface of the connecting seat 410 through a torsion spring 411, and a tape measure 413 is wrapped around the surface of the reel 412, and a clamping block 414 is fixedly connected to the end of the tape measure 413, and the clamping block 414 is clamped inside the limit column 409.

[0053] In the present technical solution, after the height and width measurements are completed, the lifting assembly 400 is controlled to move to an appropriate position, and the winding assembly is moved out so that the rotating shaft 407 is close to the front side of the student. At this time, the stepper motor 406 is started, and the stepper motor 406 drives the arc rod 408 to rotate. During the rotation, the block 414 between the limit columns 409 is driven to rotate synchronously, so that the tape measure 413 on the block 414 is pulled away from the reel 412, and the tape measure 413 is rotated from the front side of the body to the back of the body. At this time, the student pulls the block 414 from the back to wind the tape measure 413 around the student. The measuring tape 413 is passed behind the body and placed in front of the body to measure the three dimensions. When the measurement is completed, the clamping block 414 is released, and the elasticity of the torsion spring 411 causes the reel 412 to rotate in the opposite direction on the connecting seat 410, so that the clamping block 414 continues to be located at the two limit posts 409 after the measuring tape 413 is wound up, and the winding mechanism is kept in an open state to continue moving the lifting assembly 400, so as to measure the circumference at different positions, which is convenient for students to operate quickly. When all the dimensions are measured, the winding mechanism is reset to drive the telescopic plate 405 to retract, which is convenient for subsequent use.
