[0037] Unless otherwise specified or defined, the "first, second..." used in this article is merely used to distinguish names and does not represent a specific quantity or order.

[0038] Unless specifically stated or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] It should be noted that when a component is considered to be "fixed to" another component, it can be directly fixed to the other component or there can be a central component; when an component is considered to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time; when an component is considered to be "installed on" another component, it can be directly installed on the other component or there can be a central component at the same time. When an component is considered to be "set on" another component, it can be directly set on the other component or there can be a central component at the same time.

[0040] The utility model provides a meter testing device 100, such as Figures 1 to 3As shown, the test device 100 includes a support assembly 1, a force measuring mechanism 3, and an adjustment assembly 2. The adjustment assembly 2 includes a moving block 21, a support block 22, and an adjustment member 23. The force measuring mechanism 3 is mounted on the moving block 21, and the support block 22 is mounted on the support assembly 1. The moving block 21 is mounted on the support block 22 and slidably cooperates with the support block 22. The adjustment member 23 is movably arranged on the support block 22. The moving block 21 has a plurality of tooth grooves 212 on one side close to the adjustment member 23. The adjustment member 23 has a plurality of convex teeth 232, and any convex tooth 232 is engaged with any tooth groove 212. Specifically, during the use of the test device 100, the adjustment member 23 is rotated to make the convex teeth 232 on the adjustment member 23 cooperate with the tooth groove 212. During the rotation process, the convex teeth 232 will push the tooth groove 212 to move, thereby driving the moving block 21 to move up and down, and driving the force measuring mechanism 3 to move downward, so that the force measuring mechanism 3 pulls the needle 41 to move downward, and the tightness of the needle 41 is tested. During the experiment, the tester can observe the needle pulling force value of the force measuring mechanism 3 when driving the adjustment member 23 to achieve rapid measurement. In some embodiments, the transmission mechanism can cooperate with the motor, and the motor drives the transmission mechanism to drive the force measuring mechanism 3 to move, so as to automatically test the needle pulling force value of the needle 41.

[0041] Preferably, by cooperating with multiple convex teeth 232 and multiple tooth grooves 212, the gear meshing principle can be utilized to improve the efficiency of power transmission of the adjusting member 23, and the transmission is smooth and reliable, and the instantaneous transmission ratio can be guaranteed to be constant. By designing the size and number of the convex teeth 232, the required rotational speed and torque can be obtained; the accuracy of the mobile force measuring mechanism 3 is improved, and at the same time, the force of driving the force measuring mechanism 3 can be saved, and the stability of the force measuring mechanism 3 when moving is improved.

[0042] Preferably, Figures 2 to 4 As shown, the moving block 21 has a guide block 211, and the supporting block 22 has a dovetail groove 222. The guide block 211 is at least partially disposed in the dovetail groove 222 and slides with the supporting block 22. Specifically, when the adjusting member 23 rotates, the protruding teeth 232 on the adjusting member 23 cooperate with the tooth groove 212 and push the guide block 211 to move up and down in the dovetail groove 222. The guide block 211 slides with the dovetail groove 222 to improve the stability of the moving block 21 when moving up and down. Moreover, the dovetail groove 222 limits the position of the guide block 211 on the supporting block 22 to prevent the guide block 211 from separating from the supporting block 22.

[0043] Preferably, Figure 3As shown, the adjusting member 23 includes a first knob 233 and an adjusting shaft 231. The outer diameter of the first knob 233 is larger than the outer diameter of the adjusting shaft 231. The first knob 233 is installed at one end of the adjusting shaft 231 away from the support block 22. The adjusting shaft 231 is at least partially rotatably arranged in the support block 22. A plurality of convex teeth 232 are arranged on the outer wall of the adjusting shaft 231, and a plurality of tooth grooves 212 are arranged on the guide block 211. Specifically, the outer diameter of the first knob 233 is relatively large, so that the adjusting member 23 can form a labor-saving lever structure. When the finger acts on the first knob 233 with a larger outer diameter, the force driving the adjusting shaft 231 to rotate can be reduced, thereby improving the convenience of driving the adjusting member 23 to rotate. The larger the difference between the outer diameters of the first knob 233 and the adjusting shaft 231, the smaller the force driving the adjusting member 23. In actual design, the outer diameter of the adjusting shaft 231 needs to be considered. The outer diameter of the adjusting shaft 231 is related to how many convex teeth 232 structures are designed.

[0044] In some embodiments, Figures 1 to 3 As shown, the adjustment assembly 2 also includes a locking member 24, one end of which passes through the support block 22 and is fixed to the support assembly 1.

The support block 22 has a through hole 221, and the through hole 221 is for one end of the support assembly 1 to pass through, so that the support block 22 is sleeved outside the support assembly 1 and is slidably arranged on the support assembly 1. Moving the support block 22 can adjust the position of the moving block 21 on the support assembly 1, thereby changing the position of the force measuring mechanism 3 on the support assembly 1. After the height of the force measuring mechanism 3 on the support assembly 1 is adjusted, the locking member 24 passes through the support block 22 and is fixed to the support assembly 1, thereby limiting the position of the support block 22 on the support assembly 1 and improving the stability of the force measuring mechanism 3 on the support assembly 1.

[0045] Preferably, Figure 3 As shown, the locking member 24 includes a fixed shaft 242 and a second knob 241, and the support assembly 1 has an axial hole matched with the fixed shaft 242. The fixed shaft 242 is at least partially installed in the support block 22 and is threadedly matched with the support block 22; the second knob 241 is installed on the fixed shaft 242 and is arranged outside the support block 22. Specifically, a plurality of axial holes can be provided on the support assembly 1, and the axial holes are arranged equidistantly in the height direction of the support assembly 1. The fixed shaft 242 is matched with any axial hole, so as to facilitate the adjustment of the installation height of the force measuring mechanism 3 on the support assembly 1; the fixed shaft 242 is threadedly matched with the support block 22, so as to improve the stability of the connection between the fixed shaft 242 and the axial hole; and it is also convenient for the assembly of the support block 22 and the support assembly 1.

[0046] In some embodiments, Figure 1 and Figure 2As shown, the support assembly 1 includes a base 11, a column 12, and a support seat 13. The first end of the column 12 is mounted on the base 11, and the support seat 13 is mounted on the second end of the column 12. The support seat 13 has a test position, and the force measuring mechanism 3 is arranged below the test position. Specifically, the base 11 is used to support the column 12 to increase the contact area between the column 12 and the ground, the column 12 is used to support the support block 13 to determine the height of the force measuring mechanism 3 on the column 12, and the support seat 13 is used to support the watch movement 4 so that the watch movement 4 is arranged on the test position, and the force measuring mechanism 3 is used to test the tightness of the watch movement 4 below the test position.

[0047] Preferably, Figure 5 As shown, the support seat 13 includes a support plate 131, a first limiting plate 133, and a second limiting plate 134. A U-shaped groove 136 is opened on the support plate 131. The first limiting plate 133 and the second limiting plate 134 are arranged opposite to each other. The first ends of the first limiting plate 133 and the second limiting plate 134 are both installed on the support plate 131. The second ends of the first limiting plate 133 and the second limiting plate 134 are both arranged close to the U-shaped groove 136, and a test position is formed between the second end of the first limiting plate 133 and the second end of the second limiting plate 134, and the test position is used to place the watch movement 4. Specifically, the first limit plate 133 and the second limit plate 134 are used to place the watch movement 4 so that the needle 41 of the watch movement 4 is at the test position, and when the force measuring mechanism 3 needs to test the needle 41, one end of the force measuring mechanism 3 passes through the U-shaped groove 136 and is fixed to the needle 41 at the test position; the force measuring mechanism 3 and the needle 41 can be fixed by binding or clamping the needle 41 with a rope. When the force measuring mechanism 3 pulls the needle 41, the watch movement 4 is abutted against the first limit plate 133 and the second limit plate 134, and the first limit plate 133 and the second limit plate 134 limit the movement of the watch movement 4, thereby testing the tightness of the needle 41 on the watch movement 4.

[0048] Preferably, Figure 5 As shown, the support assembly 1 also has three fasteners 132, and a mounting hole 135 is provided on the support plate 131. The mounting hole 135 is for one end of the column 12 to pass through. The column 12 has three connecting holes. One ends of the three fasteners 132 pass through the support plate 131 from three different directions respectively and are fixed to the three connecting holes of the column 12. Specifically, the number of connecting holes corresponds to the number of fasteners 132, and the positions of the connecting holes correspond to the directions in which the fasteners 132 are inserted. By the three fasteners 132 passing through the support plate 131 in three different directions and then being fixed to the column 12, the stability of the support plate 131 on the column 12 can be improved, which is beneficial for the support plate 131 to provide strong support for the watch movement 4 when the force measuring mechanism 3 pulls the watch needle 41, so as to prevent the watch movement 4 from pushing the support plate 131 to move after being subjected to tension, or to prevent the support plate 131 from cracking.

[0049] In some embodiments, Figure 2 and Figure 6 As shown, the force measuring mechanism 3 includes a force measuring instrument 31 and a clamping member 32, wherein the first end of the clamping member 32 is mounted on the force measuring instrument 31, and the second end of the clamping member 32 is arranged near the test position; the clamping member 32 includes a first clamping arm 322, a second clamping arm 323, and a clamping seat 321, wherein the clamping seat 321 is mounted on the test end of the force measuring instrument 31, the first ends of the first clamping arm 322 and the second clamping arm 323 are both mounted on the clamping seat 321, the second ends of the first clamping arm 322 and the second clamping arm 323 pass through the U-shaped groove 136, and a clamping position 324 is formed between the second end of the first clamping arm 322 and the second end of the second clamping arm 323, the clamping position 324 is arranged near the test position, and the clamping position 324 is used to clamp the hands 41 of the watch movement 4. Specifically, after passing through the U-shaped groove 136, the first clamping arm 322 and the second clamping arm 323 of the clamping member 32 clamp the watch needle 41 from two directions respectively, so that the watch needle 41 is fixed by the clamping member 32, and the test end of the dynamometer 31 is connected to the clamping seat 321. The dynamometer 31 applies a tensile force to the watch needle 41 of the watch movement 4 through the clamping member 32, thereby testing the tightness of the watch needle 41 on the watch movement 4. When the watch needle 41 is separated from the watch movement 4, the dynamometer 31 can also test the maximum tensile force after the watch needle 41 is separated from the watch movement 4.

[0050] Preferably, Figure 7 As shown, the first clamp arm 322 and the second clamp arm 323 are both bent, and the bent portion 325 of the first clamp arm 322 and the second clamp arm 323 is arranged close to the clamping position 324; the bent portion 325 has a notch, and the notch is used to accommodate the watch core shaft of the watch 4. Specifically, when the inner wall of the notch abuts against the watch core shaft, the upper end face and the lower end face of the bent portion 325 abut against the watch core 4 and the watch hand 41 respectively, so as to clamp the watch hand 41.

[0051] It should be noted that the adjusting member 23 of the meter test device 100 is used to rotate the adjusting member 23 after the force measuring mechanism 3 is fixed to the needle 41 on the support assembly 1, so that the convex teeth 232 move on the multiple tooth grooves 212, and drive the moving block 21 to slide on the support block 22, thereby improving the accuracy of the moving block 21 when moving, and driving the force measuring mechanism 3 to move, so that the force measuring mechanism 3 applies a pulling force to the needle 41; through actual operation and data analysis, the rapid measurement of the needle pulling force of the needle 41 aperture can be achieved, which can accurately reflect the needle pulling force value of the needle 41, reduce the influence of human factors on the judgment of the tightness of the needle hole, provide strong support for quality control in the production process, and improve production efficiency and product quality control. In this embodiment, by rotating the adjusting member 23, the multiple convex teeth 232 on the adjusting member 23 are engaged with the multiple tooth grooves 212 of the moving block 21, so that the force measuring mechanism 3 moves up and down, so that the force measuring mechanism 3 applies a pulling force to the needle 41, and the tightness of the needle 41 is tested. In other embodiments, the gear transmission structure drives the force measuring mechanism 3 to move, and the tightness of the needle 41 can be tested, and no special limitation is made here. When citing drawings, new features are described; in order to avoid repeated citation of drawings resulting in less concise description, the drawings will not be cited one by one if the features have been described clearly.
