[0002] The watch case is usually the outer shell of the watch body (watch head), and its function is to contain and protect the internal parts of the watch (movement, dial, hands, etc.). The parts closely connected to the watch case include: watch mirror, bottom cover, crown, buttons, etc. The watch is composed of a stainless steel case and a stainless steel strap, and the side of the stainless steel case is generally equipped with function buttons. As we all know, the function buttons are installed in the button holes of the stainless steel case. During the assembly of the function buttons, the buttons on the watch case need to be checked to ensure the conductivity between the buttons and the movement after assembly, and also to prevent the installation from over-travel and damage or reducing the service life of the movement;

[0003] When testing existing watch case buttons, the buttons are generally introduced into the equipment for testing. During the process of full inspection of the watch case buttons, the watch case buttons are tested in the equipment, and the testing cost is high. In addition, the test can only be performed on the watch case and buttons after overall assembly, and it is impossible to distinguish the specific buttons that cause problems. Therefore, it is necessary to develop a low-cost travel detection device that can accurately distinguish buttons with incorrect travel. Utility Model Content

[0006] Furthermore, the above-mentioned detection slide rods are through-gauge slide rods, and each through-gauge slide rod slides under the drive of the corresponding button on the watch case. After the through-gauge slide rod slides, each detection block is pressed against the positioning block to form an electrical connection with the positioning block.

[0007] Furthermore, the above-mentioned detection slide rod is a stop gauge slide rod, and each stop gauge slide rod slides under the drive of a corresponding button on the watch case. After each detection block slides, it is pressed against the positioning block and forms an electrical connection with the positioning block.

[0008] Furthermore, each positioning groove is arranged on the upper end surface of the detection block, and the positioning groove includes a middle groove arranged on the upper end surface and can be used for limiting the reset spring, and side through grooves arranged on both sides of the middle groove and for the detection slide rod to slide. The detection slide rod is provided with a limit block coaxially arranged with the detection slide rod, and the limit block is slidably arranged in the side through groove under the drive of the detection slide rod.

When the key is tested for the through gauge, each detection slide bar contacts and presses against the positioning block to form a closed loop circuit in series. If a buzzer sounds, the through gauge test is qualified. When the stop gauge test is performed, each detection slide bar does not contact the positioning block to generate a closed loop circuit. If no buzzer sounds, the stop gauge test is qualified. A plurality of detection slide bars are set to adapt to a plurality of keys to ensure that the stroke of each key can be detected, which effectively solves the problem that keys with too large or too small strokes cannot be specifically distinguished in the prior art.

[0025] The detection slide bars 44 are through-gauge slide bars, and each through-gauge slide bar slides under the drive of the corresponding button on the watch case. Each detection block 43 is pressed against the positioning block 42 after the through-gauge slide bar slides to form an electrical connection with the positioning block 42.

[0026] The detection slide bar 44 is a stop gauge slide bar, and each stop gauge slide bar slides under the drive of a corresponding button on the watch case. Each detection block 43 is electrically connected to the positioning block 42 by pressing against the positioning block 42 after the stop gauge slide bar slides.

[0027] Each positioning groove 48 is arranged on the upper end surface of the detection block 43, and the positioning groove 48 includes a middle groove 481 arranged on the upper end surface and can be used to limit the reset spring 47, and side grooves 482 arranged on both sides of the middle groove 481 and can be used for the detection slide bar 44 to slide. The detection slide bar 44 is provided with a limit block 46 coaxially arranged with the detection slide bar 44. The limit block 46 is slidably arranged in the side groove 482 under the drive of the detection slide bar 44. The diameter of the limit block 46 is smaller than the groove width of the middle groove 481, and the upper end of the limit block 46 is higher than the upper end surface of the detection block 43.

[0028] A positioning plate 45 is fixedly mounted on the detection block 43, and a limiting through groove 451 corresponding to the middle groove 481 is provided on the positioning plate 45. The limiting through groove 451 is connected to each middle groove 481, and the upper end surface of the positioning plate 45 is higher than the upper end of the limiting block 46. The end of each limiting block 46 away from the positioning block 42 is pressed against the inner wall of the limiting through groove 451 by the continuous force of the reset spring 47.

[0029] The positioning block 42 is provided with connecting grooves 49 corresponding to each detection slide bar 44 and into which each detection slide bar 44 can be inserted. The detection block 43 is inserted into the corresponding connecting groove 49 through any detection slide bar 44 and pressed against the bottom of the connecting groove 49 to form an electrical connection with the positioning block 42.

[0030] The working principle of the utility model is as follows: the through gauge slide bar and the stop gauge slide bar are both used to detect the stroke of the buttons on the watch case, and the length of the stop gauge slide bar is smaller than that of the through gauge slide bar. The operator first performs a through gauge detection on the buttons on the watch case, first places the watch case with buttons on the placement plate 41, and then positions the dial through the positioning block 42. When detecting each button on the dial, the button to be detected is pressed, and the button drives the detection slide bar 44 during the pressing process. The detection slide bar 44 extends into the connecting groove 49 on the positioning block 42 and contacts the bottom of the connecting groove 49. Because the positioning block 42, the detection slide bar 44, the detection block 43, etc. are all conductive metal parts, and the battery 2 forms a series circuit with the positioning block 42, the detection slide bar 44, the detection block 43, and the buzzer 3. Therefore, when the detection slide bar 44 is connected to the connecting groove 49 and the buzzer 3 alarms, the through gauge detection is qualified. If the buzzer 3 does not sound, the through gauge detection is unqualified.

[0031] The watch case that has passed the through gauge test is transferred to the inspection fixture body with a stop gauge slide bar. The operator places the watch case on the placement plate 41, and then positions the dial through the positioning block 42. When testing each button on the dial, the button to be tested is pressed. The button drives the detection slide bar 44 during the pressing process. If the detection slide bar 44 fails to contact the bottom of the connecting groove 49, the series circuit fails to be connected, and the buzzer 3 fails to alarm, then the stop gauge test of the button is qualified. If the series circuit is connected and the buzzer 3 alarms, then the stop gauge test of the button is unqualified.

[0032] The utility model is provided with two detection slide bars 44, and the travel of the key is comprehensively detected by the cooperation of the through gauge slide bar on the inspection tool body and the key, and the cooperation of the stop gauge slide bar on the inspection tool body and the key, and the sliding travel of the key to be detected is determined by the standard through gauge slide bar and the stop gauge slide bar, which effectively solves the problems of high detection cost and inability to perform individual detection on specific keys with longer or shorter travels in the prior art, and the equipment is replaced by the inspection tool, which greatly reduces the cost of the equipment, and at the same time, by providing multiple detection slide bars 44, each key is individually detected by the cooperation of each detection slide bar 44 and the corresponding key, so as to ensure that each key can perform accurate travel detection, and through the through gauge slide bar and the stop gauge slide bar, the through gauge slide bar can be used to detect the minimum value of the key travel, and the stop gauge slide bar can be used to detect the maximum value of the key travel, so as to accurately and efficiently detect the travel range of the key, thereby achieving comprehensive and accurate detection of the watch case and the key, and the structure is ingenious, stable and practical.
