[0002] Sealing rings are an indispensable part of watch design. They not only ensure the watch's water and dust resistance but are also a key element in its function as a fashion accessory and practical tool. In today's market environment, watch products are constantly being updated and replaced at an increasingly diverse pace. As a crucial component ensuring a watch's water resistance, the accuracy of the sealing ring's dimensions directly affects the watch's sealing performance and lifespan. If the sealing ring's size does not meet specifications, water or dust may easily enter the watch, affecting its normal use. Therefore, it is necessary to accurately measure the sealing ring's size to ensure a perfect fit with the watch case, thus providing a strong guarantee for the watch's high quality.

[0003] However, when testing the dimensions of a sealing ring, contact measuring tools (such as calipers) apply pressure to the sealing ring during measurement, causing the flexible material sealing ring to deform, thus generating measurement errors. Summary of the Invention

[0011] The first adjustment component is at least partially located within the first mounting groove and engages with the inner wall of the first mounting groove.

[0012] In one embodiment, the regulator further includes a second adjustment component mounted on the movable column. The second adjustment component has a micro-adjustment element that cooperates with the outer wall of the movable column. The micro-adjustment element includes a ball. The movable column has multiple toothed grooves that cooperate with the ball. The multiple toothed grooves are equidistantly distributed on the outer wall of the movable column, and the ball abuts against any one of the multiple toothed grooves.

[0013] In one embodiment, the micro-adjustment component includes an elastic element and a third rotating block, the third rotating block being mounted on the end of the movable column and detachably connected to the first adjustment component;

[0015] In one embodiment, the second adjustment component further includes a first fastener, a positioning pin, and a spring. The first end of the first fastener is mounted on the end of the movable column. The spring and the third rotating block are both sleeved on the outside of the first fastener, and the third rotating block abuts against the second end of the first fastener. The two ends of the spring abut against the movable column and the third rotating block, respectively.

[0016] The positioning pin is mounted on the third rotating block, and the first adjusting component has a positioning groove that mates with the positioning pin; and / or, the positioning pin is mounted on the first adjusting component, and the third rotating block has a positioning groove that mates with the positioning pin.

[0017] In one embodiment, the tooth groove includes a sliding groove and a guide groove, the cross-sectional area of ​​the guide groove gradually decreases from one end to the other end, and the larger end of the guide groove is connected to the sliding groove.

[0018] In one embodiment, a moving block is further provided between the moving column and the extrusion ball head.

Since the extrusion groove is conical, its first inner diameter is larger than its second inner diameter. The outer diameter of the extrusion ball head of the adjuster is larger than the second inner diameter of the extrusion groove but smaller than its first inner diameter. The extrusion ball head can enter the extrusion groove from the larger end and move towards the smaller end. When the extrusion ball head reaches the smaller end, it presses against the inner wall of the extrusion groove, causing the telescopic clamp to expand radially. The outer wall of the telescopic clamp presses against the inner wall of the sealing ring, keeping the sealing ring taut in the clamping position. When the telescopic clamp opens or closes, the sealing ring is subjected to uniform force, eliminating measurement errors caused by the thinness and easy deformation of the sealing ring, and improving the accuracy of dimensional detection.

[0035] To facilitate understanding of this utility model, the specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings.

[0036] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0037] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0038] It should be noted that when a component is considered "fixed" to another component, it can be directly fixed to the other component or there can be an intervening component; when a component is considered "connected" to another component, it can be directly connected to the other component or there can be an intervening component; when a component is considered "mounted" on another component, it can be directly mounted on the other component or there can be an intervening component; when a component is considered "placed" on another component, it can be directly placed on the other component or there can be an intervening component.

[0039] This utility model proposes a measuring clamping device 100, such as... Figures 1 to 6 As shown, the device includes a base 1, a telescopic clamping member 2, and an adjuster 4. The telescopic clamping member 2 is mounted on the base 1, and its outer wall has a clamping position 222. A compression groove 221 is formed inside the telescopic clamping member 2. The compression groove 221 is conical in shape and has a first inner diameter and a second inner diameter. The first inner diameter is located at the large end of the compression groove 221, and the second inner diameter is located at the small end of the compression groove 221. The first inner diameter is larger than the second inner diameter. The adjuster 4 has a compression ball head 41. The outer diameter of the compression ball head 41 is larger than the second inner diameter of the compression groove 221 and smaller than the first inner diameter of the compression groove 221. The compression ball head 41 is movably disposed in the compression groove 221 and has at least a first moving position in the compression groove 221. In the first moving position, the compression ball head 41 abuts against the inner wall of the compression groove 221.

[0040] In some embodiments, the base 1 has a fixing groove 11 and a second fastener 12. The fixing groove 11 is U-shaped. The telescopic clamp 2 is installed in the fixing groove 11. The two side walls of the telescopic clamp 2 abut against the inner wall of the fixing groove 11. The telescopic clamp 2 is fixed on the base 1 by the second fastener 12, thereby improving the stability of the telescopic clamp 2 on the base 1.

[0041] During measurement, the sealing ring 6 is fitted over the telescopic clamp 2, and the sealing ring 6 is located on the clamping position 222. The adjuster 4 is pushed into the extrusion groove 221. Since the extrusion groove 221 is conical, the first inner diameter of the extrusion groove 221 is larger than the second inner diameter. The outer diameter of the extrusion ball head 41 of the adjuster 4 is larger than the second inner diameter of the extrusion groove 221 and smaller than the first inner diameter of the extrusion groove 221. The extrusion ball head 41 can enter the extrusion groove 221 from the large end and move towards the small end of the extrusion groove 221. When the extrusion ball head 41 moves to the small end of the extrusion groove 221, the extrusion ball head 41 extrudes the inner wall of the extrusion groove 221, and the telescopic clamp 2 generates a radial expansion effect. The outer wall of the telescopic clamp 2 extrudes the inner wall of the sealing ring 6, and the sealing ring 6 is in a tensioned state on the clamping position 222. When the telescopic clamp 2 opens or contracts, the sealing ring 6 is subjected to uniform force, eliminating the measurement error caused by the thinness and easy deformation of the sealing ring 6, and improving the accuracy of dimensional detection.

[0042] Furthermore, the extrusion groove 221 of the telescopic clamp 2 is conical in shape. By moving the position of the extrusion ball head 41, the radial dimension change of the telescopic clamp 2 can be adjusted. This adjustment method is simple and easy to operate, reducing the detection error caused by the difference in the technical level and experience of different operators.

[0043] In this embodiment, the telescopic clamp 2 can be made of an elastic material, so that it expands when squeezed by the extrusion ball head 41.

[0044] In some embodiments, the telescopic clamping member 2 has an L-shaped groove on one side away from the large end of the extrusion groove 221. The L-shaped groove extends circumferentially along the telescopic clamping member 2 and forms a clamping position 222. A sealing ring 6 is used to be disposed on the clamping position 222.

[0045] In some embodiments, the telescopic clamp 2 further has a first mounting groove 211, which communicates with the extrusion groove 221; the adjuster 4 includes a first adjusting component 3, a moving block 45, and a moving column 42, with the extrusion ball head 41, the moving block 45, and the moving column 42 being fixedly connected in sequence; the first adjusting component 3 is sleeved on the outside of the moving column 42 and slides in cooperation with the moving column 42, and the first adjusting component 3 is used to abut against the moving block 45; the first adjusting component 3 is at least partially located in the first mounting groove 211 and cooperates with the inner wall of the first mounting groove 211.

[0046] Specifically, the first adjusting component 3 is used to cooperate with the first mounting groove 211. When the first adjusting component 3 rotates in the first mounting groove 211, the first adjusting component 3 can move along the axis of the moving column 42 and abut against the moving block 45. Therefore, when the first adjusting component 3 moves, it can push the moving block 45 toward the extrusion groove 221. The extrusion ball head 41, the moving block 45, and the moving column 42 are fixedly connected in sequence, and at the same time, the extrusion ball head 41 abuts against the inner wall of the extrusion groove 221, further realizing the extrusion telescopic clamping component 2.

[0047] In this embodiment, the first adjustment component 3 performs a coarse adjustment in adjusting the movement of the extrusion ball head 41, so that the telescopic clamping member 2 can clamp the sealing ring 6 and improve the stability of the sealing ring 6 at the clamping position 222.

[0048] In some embodiments, the adjuster 4 further includes a second adjusting component 5, which is mounted on the movable column 42 and is detachably coupled to the first adjusting component 3. The second adjusting component 5 has a micro-adjustment element 54, which engages with the outer wall of the movable column 42. Specifically, the second adjusting component 5 is detachably coupled to the first adjusting component 3. When the second adjusting component 5 is separated from the first adjusting component 3, coarse adjustment is achieved by driving the first adjusting component 3. When the second adjusting component 5 is coupled to the first adjusting component 3, the micro-adjustment element 54 of the second adjusting component 5 engages with the outer wall of the movable column 42, and the micro-adjustment element 54 performs micro-adjustment on the first adjusting component 3, thereby improving the sensitivity of the first adjusting component 3 during adjustment and achieving micro-adjustment of the extrusion ball head 41.

[0049] In this embodiment, when the extrusion ball head 41 performs micro-motion extension and retraction, the telescopic clamping member 2 adapts to the sealing ring 6 of different sizes. Traditional testing methods require multiple replacements of the outer diameter plug gauge until it is adapted. By using the second adjustment component 5 to fine-tune the telescopic clamping member 2 to adapt it, the testing time can be reduced and the measurement efficiency can be greatly improved.

[0050] Preferred, such as Figure 2 and Figure 3As shown, the micro-adjustment component 54 includes an elastic element 541, a ball 542, and a third rotating block 52. The third rotating block 52 is installed at the end of the moving column 42 and is detachably connected to the first adjustment component 3. The inner wall of the third rotating block 52 has a second mounting groove. The elastic element 541 is disposed in the second mounting groove, and the first end of the elastic element 541 abuts against the bottom wall of the second mounting groove. The ball 542 is installed at the second end of the elastic element 541. The moving column 42 has a plurality of toothed grooves 43 that cooperate with the ball 542. The plurality of toothed grooves 43 are equidistantly distributed on the outside of the moving column 42, and the ball 542 abuts against any one of the toothed grooves 43. Specifically, the ball 542 is installed in the second mounting groove by the elastic element 541. When the ball 542 abuts against the bottom wall of the toothed groove 43, the elastic element 541 will apply a force to the ball 542, so that the ball 542 is always in contact with the bottom wall of the toothed groove 43.

[0051] When the third rotating block 52 is connected to the first adjusting component 3, during the rotation of the third rotating block 52, the ball 542 slides in contact with the toothed groove 43. When the ball 542 moves from one toothed groove 43 to the next, the force generated by the elastic element 541 causes the ball 542 to strike the bottom wall of the toothed groove 43, making the second adjusting component 5 produce a clicking sound. The clicking sound produced by rotating the third rotating block 52 indicates the adjustment range of the second adjusting component 5. Since multiple toothed grooves 43 are equidistantly distributed outside the moving column 42, the adjustment range is equal each time the ball 542 strikes a toothed groove 43. The operator uses the clicking sound produced by the second adjusting component 5 as a reference to judge the rotation angle or rotation path of the first adjusting component 3, further realizing the fine adjustment of the second adjusting component 5. When the third rotating block 52 is separated from the first adjusting component 3, the telescopic clamp 2 can be coarsely adjusted by adjusting the first adjusting component 3.

[0052] Preferably, to facilitate quick disassembly and connection between the third rotating block 52 and the first adjusting assembly 3, such as... Figure 4 and Figure 5 As shown, the second adjusting component 5 also includes a first fastener 51, a positioning pin 53, and a spring 55. The first end of the first fastener 51 is installed on the end of the moving column 42. The spring 55 and the third rotating block 52 are both sleeved on the outside of the first fastener 51, and the third rotating block 52 abuts against the second end of the first fastener 51. The two ends of the spring 55 abut against the moving column 42 and the third rotating block 52, respectively. The positioning pin 53 is installed on the third rotating block 52, and the first adjusting component 3 has a positioning groove 56 that cooperates with the positioning pin 53. And / or, the positioning pin 53 is installed on the first adjusting component 3, and the third rotating block 52 has a positioning groove 56 that cooperates with the positioning pin 53.

[0053] Specifically, when the third rotating block 52 moves, it will compress the spring 55, and the spring 55 will generate a force. When the force acting on the third rotating block 52 disappears, the force generated by the spring 55 will reset the third rotating block 52, and the positioning pin 53 will separate from the positioning groove 56, so as to realize the quick disassembly and connection between the third rotating block 52 and the first adjusting component 3.

[0054] Furthermore, when the third rotating block 52 moves along the axis of the moving column 42 and toward the extrusion groove 221, the positioning groove 56 on the third rotating block 52 engages with the positioning pin 53 on the second rotating block 32, and the third rotating block 52 and the second rotating block 32 are fixed in the axis of the moving column 42; when the third rotating block 52 is rotated, the third rotating block 52 drives the second rotating block 32 to rotate, and the ball 542 on the third rotating block 52 engages with the multiple toothed grooves 43 on the outer wall of the moving column 42, and the third rotating block 52 drives the first adjusting component 3 to make a micro-adjustment, so that the first adjusting component 3 makes a micro-adjustment of the telescopic clamping member 2.

[0055] Preferably, to improve the passage of the ball 542 into the tooth groove 43 when the third rotating block 52 and the second rotating block 32 are connected, such as... Figure 6 As shown, the toothed groove 43 includes a sliding groove 432 and a guide groove 431. One end of the guide groove 431 gradually decreases in size from the other end, and the larger end of the guide groove 431 is connected to the sliding groove 432. Specifically, when the third rotating block 52 moves toward the extrusion groove 221, the smaller end of the guide groove 431 guides the ball 542 into the guide groove 431. Since the larger end of the guide groove 431 is connected to the sliding groove 432, as the positioning pin 53 enters the positioning groove 56, the ball 542 will move into the sliding groove 432, realizing the engagement of the ball 542 with the toothed groove 43 and improving the passability of the ball 542 into the toothed groove 43.

[0056] In some embodiments, the first adjustment component 3 includes a first rotating block 31 and a second rotating block 32. The first rotating block 31 and the second rotating block 32 are integrally formed. The first rotating block 31 abuts against the moving block 45. The first rotating block 31 has an external thread on its exterior and an internal thread in the first mounting groove 211. The first rotating block 31 is threadedly connected to the telescopic clamping member 2, and the second rotating block 32 is disposed outside the first mounting groove 211. Specifically, by rotating the second rotating block 32, the first rotating block 31 is driven to rotate. Since the first rotating block 31 is threadedly connected to the first mounting groove 211, the first rotating block 31 will move within the first mounting groove 211 when rotating. Since the first rotating block 31 abuts against the moving block 45, the first rotating block 31 can push the moving block 45 and the squeeze ball head 41 to move when moving, thereby achieving coarse adjustment of the telescopic clamping member 2.

[0057] Preferably, to prevent the extrusion ball head 41 from rotating, the adjuster 4 also has a limiting pin 44, which is mounted on the moving block 45; the inner wall of the telescopic clamp 2 has a limiting groove, which extends along the axis of the moving column 42, and the limiting pin 44 slides in conjunction with the limiting groove. Specifically, the limiting pin 44 slides in conjunction with the limiting groove, and the limiting groove limits the movement direction of the limiting pin 44. By mounting the limiting pin 44 on the moving block 45, the movement direction of the moving block 45 is restricted; and since the moving block 45 is fixed to the extrusion ball head 41, rotation of the extrusion ball head 41 within the extrusion groove 221 can be prevented.

[0058] In some embodiments, the telescopic clamping member 2 includes a connecting sleeve 21 and a clamping head 22. The connecting sleeve 21 is mounted on the clamping head 22. A pressing groove 221 is formed inside the clamping head 22. The large end of the pressing groove 221 is located at the first end of the clamping head 22, and the small end of the pressing groove 221 is located at the second end of the clamping head 22. A clamping position 222 is disposed at the second end of the clamping head 22. A first mounting groove 211 is formed inside the connecting sleeve 21. The clamping head 22 includes a plurality of clamping blocks 223. The plurality of clamping blocks 223 are mounted on the connecting sleeve 21 and distributed along the circumference of the connecting sleeve 21. There is a gap 23 between two adjacent clamping blocks 223.

[0059] Specifically, since the clamping position 222 is located at the second end of the clamping head 22, and the small end of the extrusion groove 221 is located at the second end of the clamping head 22, the second end of the clamping head 22 deforms the most when the extrusion ball head 41 extrudes the clamping head 22 in the extrusion groove 221. When the sealing ring 6 is installed in the clamping position 222, the sealing ring 6 can be quickly tensioned by the clamping head 22. The clamping head 22 includes multiple clamping blocks 223, and there is a gap 23 between two adjacent clamping blocks 223. By utilizing this gap 23, the expansion effect of the clamping head 22 is more obvious when multiple clamping blocks 223 are extruded, thus meeting the deformation requirements of the clamping head 22.

[0060] This utility model also proposes a measurement clamping method for the measurement clamping device 100, including the following steps:

[0061] Step 1: Push the extrusion ball head 41 into the extrusion groove 221, and move the extrusion ball head 41 from the large end of the extrusion groove 221 to the small end of the extrusion groove 221;

[0062] Step 2: The extrusion ball head 41 moves to the first moving position, and the extrusion ball head 41 extrudes the inner wall of the extrusion groove 221. The telescopic clamping member 2 is in an expanded state and fixes the sealing ring 6 on the clamping position 222.

[0063] Specifically, this measurement clamping method is simple and easy to operate, reducing detection errors caused by differences in the technical level and experience of different operators.

[0064] Preferably, the change in the outer diameter of the telescopic clamp 2 for each time the marble 542 jumps over a tooth groove 43 is expressed by the formula:

[0065]

[0066] Wherein, d is the change in the outer diameter of the telescopic clamp 2 (unit: mm); m is the number of tooth grooves 43; p is the pitch of the first adjusting component 3 (unit: mm / turn); θ is the taper angle of the extrusion groove 221 (unit: radians); α is the rotation angle of the thread in the first adjusting component 3 (unit: radians), which can be used to represent the rotation angle of the external thread on the first rotating block 31.

[0067] Specifically, by setting the number of toothed grooves 43, the pitch of the external thread in the first adjusting component 3, the taper of the extrusion groove 221, and the rotation angle of the thread in the first adjusting component 3, the change in the outer diameter of the telescopic clamping member 2 can be calculated.

[0068] When referencing drawings, new features are explained. To avoid redundant references to drawings that would make the description less concise, features already described will not be referenced again on the drawings if the description is clear.

[0069] The purpose of the above embodiments is to reproduce and derive the technical solution of this utility model by way of example, and to fully describe the technical solution, purpose and effect of this utility model. The purpose is to enable the public to have a more thorough and comprehensive understanding of the disclosed content of this utility model, and it is not intended to limit the protection scope of this utility model.

[0070] The above embodiments are not an exhaustive list based on the present invention, and there may be other embodiments not listed. Any substitutions and improvements made without departing from the concept of the present invention are within the protection scope of the present invention.
