[0018] By adopting the above technical solution, the rubber material has a high coefficient of friction, which can effectively increase the friction between the support leg and the contact surface, prevent the measuring box from sliding during use, and ensure the stability of the device during the measurement process.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0020] 1. In this utility model, by setting a placement groove, the main body of the rear cover glass is placed at the diagonal of the placement groove, and the two sides of the main body of the rear cover glass are in contact with the two inner walls of the placement groove. By rotating the knob, the lead screw is driven to rotate. Since the lead screw is threadedly connected to the adjusting block, the position of the adjusting block can be adjusted by rotating the lead screw to move it closer to the main body of the rear cover glass until the abutting block is in contact with the outer wall of the main body of the rear cover glass, thus fixing the main body of the rear cover glass. At this time, the measuring personnel can read the scale value displayed by the length and width measuring scale by observing the direction of the pointer, obtain the size data of the main body of the rear cover glass, and complete the size measurement.
[0021] 2. In this utility model, before placing the rear cover glass body, the protrusion is pulled to move the sliding block upward so that the rear cover glass body can be placed under the upper pressure plate. After placement, the protrusion is released and the sliding block moves downward under the elastic force of the spring until the lower surface of the upper pressure plate is in contact with the upper surface of the rear cover glass body.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0030] like Figure 1 - Figure 4As shown in the figure, this embodiment provides a dimensional measuring device for the production and inspection of mobile phone back cover glass. It includes a measuring box 1, with a placement groove 2 on the top of the measuring box 1. The back cover glass body 3 is placed inside the placement groove 2. Two adjustment grooves 4 are symmetrically arranged on the upper surface of the measuring box 1 about its diagonal. A length and width measuring scale 10 is provided on the upper surface of the measuring box 1 outside the adjustment grooves 4. A lead screw 5 is rotatably connected to the inside of each adjustment groove 4 via bearings. One end of the lead screw 5 extends through the measuring box 1 through a bearing to the outside and is fixedly connected to a knob 6. An adjustment block 7 is threadedly sleeved on the outer surface of the lead screw 5 inside the adjustment groove 4. An abutment block 8 is fixedly connected to the bottom of the adjustment block 7, and a pointer 9 is fixedly connected to the top of the adjustment block 7. The pointer 9 is located directly above the length and width measuring scale 10. In use, place the back cover glass body 3 at the opposite corner of the placement slot 2, and make the two sides of the back cover glass body 3 fit against the two inner walls of the placement slot 2. Rotate the knob 6 to drive the lead screw 5 to rotate. Since the lead screw 5 is threadedly connected to the adjusting block 7, the position of the adjusting block 7 can be adjusted by rotating the lead screw 5 to move it closer to the back cover glass body 3 until the abutment block 8 fits against the outer wall of the back cover glass body 3, thus fixing the back cover glass body 3. At this time, the measuring personnel can read the scale value displayed on the length and width measuring scale 10 by observing the direction of the pointer 9, obtain the size data of the back cover glass body 3, and complete the size measurement.
[0031] In this embodiment, as Figure 2 and 4 As shown, a lifting groove 13 is provided on the upper surface of the measuring box 1. A sliding block 14 is slidably inserted into the lifting groove 13. A protrusion 18 is fixedly connected to the top of the sliding block 14. A circular groove 16 is provided at the bottom of the sliding block 14. A spring 17 is fixedly connected inside the circular groove 16. The lower end of the spring 17 is fixedly connected to the bottom wall of the lifting groove 13. An upper pressure plate 15 is fixedly connected to one side of the sliding block 14. The lower surface of the upper pressure plate 15 is in contact with the upper surface of the rear cover glass body 3. A height measuring device is provided on the side wall of the sliding block 14. When using the scale 19, before placing the rear cover glass body 3, the protrusion 18 is pulled to move the sliding block 14 upwards so that the rear cover glass body 3 can be placed under the upper pressure plate 15. After placement, the protrusion 18 is released, and the sliding block 14 moves downwards under the elastic force of the spring 17 until the lower surface of the upper pressure plate 15 is in contact with the upper surface of the rear cover glass body 3. The thickness data of the rear cover glass body 3 can be obtained by reading the scale value displayed by the height measuring scale 19 at this time.
[0032] In this embodiment, as Figure 1-4As shown, the length scale value of the length and width measuring scale 10 matches the side length of the placement slot 2, and the height scale value of the height measuring scale 19 matches the height of the sliding block 14. During use, ensure that the scale values displayed by the length and width measuring scale 10 and the height measuring scale 19 are compatible with the size data of the rear cover glass body 3 to ensure the accuracy of the measurement data.
[0033] In this embodiment, as Figure 2 and 3 As shown, there is a gap between the bottom of the abutment block 8 and the placement groove 2. The bottom of the adjusting block 7 is fixedly connected to the support block 11 on one side of the abutment block 8. The side wall of the support block 11 is rotatably mounted with a moving wheel 12, which reduces friction during use and makes the movement of the adjusting block 7 smoother.
[0034] In this embodiment, as Figure 1 As shown, both the lead screw 5 and the adjusting block 7 are stainless steel components. The outer wall of the adjusting block 7 is in contact with the inner wall of the adjusting groove 4. During use, the stainless steel components are not easily corroded and have a long service life. The outer wall of the adjusting block 7 is in contact with the inner wall of the adjusting groove 4 to ensure that the adjusting block 7 will not deviate radially when it moves under the driving action of the lead screw 5.
[0035] In this embodiment, as Figure 3 As shown, the outer surface of the knob 6 is uniformly provided with several anti-slip grooves 601 along its circumference. When in use, the uniformly distributed anti-slip grooves 601 can significantly improve the hand friction during operation.
[0036] In this embodiment, as Figure 1 As shown, the bottom of the measuring box 1 is fixedly connected to four support legs 20 arranged in a linear array. The support legs 20 are made of rubber material. When in use, the rubber material has a high coefficient of friction, which can effectively increase the friction between the support legs 20 and the contact surface, thus preventing the measuring box 1 from sliding during use and ensuring the stability of the device during the measurement process.
[0037] The working principle of this utility model is as follows: When using the dimensional measuring device for the production inspection of mobile phone back cover glass according to this application, before placing the back cover glass body 3, the protrusion 18 is pulled to move the sliding block 14 upward, and then the back cover glass body 3 is placed at the diagonal of the placement groove 2, so that the two sides of the back cover glass body 3 are in contact with the two inner walls of the placement groove 2. After placement, the protrusion 18 is released, and the sliding block 14 moves downward under the elastic force of the spring 17 until the lower surface of the upper pressure plate 15 is in contact with the upper surface of the back cover glass body 3. The thickness data of the rear cover glass body 3 can be obtained by reading the scale value displayed on the height measuring scale 19. By rotating the knob 6, the lead screw 5 is rotated to adjust the position of the adjusting block 7 so that it moves closer to the rear cover glass body 3 until the abutment block 8 is in contact with the outer wall of the rear cover glass body 3, thus fixing the rear cover glass body 3. At this time, the measuring personnel can read the scale value displayed on the length and width measuring scale 10 by observing the direction of the pointer 9 to obtain the size data of the rear cover glass body 3 and complete the size measurement.
