Therefore, crystal oscillators are usually tested for resistance using a multimeter before production to promptly detect and resolve potential problems and ensure the normal operation of electronic equipment.
[0004] Through long-term observation, it is found that when an existing crystal oscillator is tested by a multimeter, two probes of the multimeter are usually used to contact the pins at both ends of the crystal oscillator respectively. However, the existing crystal oscillator is small in size and lacks a fixed structure during the test process, so that during the test process, the crystal oscillator is easily affected by external forces and position displacement occurs, affecting the accuracy and speed of the crystal oscillator test. Therefore, a rapid detection device for a crystal oscillator is proposed to address the above problems. Utility Model Content

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] like Figure 1-5As shown, a rapid detection device for a crystal oscillator comprises a multimeter body 1; two sets of probe bodies 11 are installed at the end of the multimeter body 1; a limiter 12 is fixedly connected to the side wall of the multimeter body 1; a rotating shaft 13 is rotatably connected to the inner wall of the limiter 12; a fixing frame 14 is fixedly connected to the middle of the rotating shaft 13; a slide bar 15 is slidably connected to the middle of the fixing frame 14; two sets of counterweights 16 are fixedly connected to the bottom of the slide bar 15; an elastic cloth 17 is fixedly connected to the middle of the counterweight 16; a bracket 18 is fixedly connected to the end of the fixing frame 14; two sets of The card hole 19; the side wall of the multimeter body 1 is fixedly connected with two groups of card pieces 110 whose shapes match the card holes 19; the middle of the card pieces 110 is fixedly connected with multiple groups of rubber barbs 111; when working, the staff needs to place the multimeter body 1 in the working area, and insert the two groups of probe bodies 11 in the middle of the multimeter body 1, turn on the multimeter body 1 and detect the crystal oscillator to be detected, by setting a limit piece 12 at the end of the multimeter body 1, and then the staff can pull the top of the slide bar 15 to make the fixing frame 14 rotate with the rotating shaft 13 as the center, and the fixing frame 14 can ... Before the fixed frame 14 is rotated, the staff can place multiple crystal oscillators side by side at the end of the multimeter body 1, so that the rotating fixed frame 14 is close to the positions of the multiple crystal oscillators, and then the slide bar 15 can be loosened. After the downward gravity of the two sets of counterweights 16 is coordinated, the middle of the elastic cloth 17 can directly contact the middle of the crystal oscillator, and the multiple crystal oscillators can be initially squeezed and fixed. When the fixed frame 14 needs to be stored as a whole, the fixed frame 14 can be rotated in the opposite direction again, so that the bracket 18 set at the end of the fixed frame 14 will gradually approach the position of the two sets of clamps 110. After the fixed frame 14 is pushed further, the clamps 110 are moved. 10 and multiple rubber barbs 111 will be stuck on the inner wall of the card hole 19 and fix the position of the fixing frame 14. This step, together with the fixing frame 14 set at the end of the multimeter body 1 and the sliding rod 15 sliding in the middle, can improve the stability of the crystal oscillator during the test process, reduce the problem of position deviation of the crystal oscillator caused by the squeezing force when the ends of the two sets of probe bodies 11 contact the output end of the crystal oscillator, improve the accuracy and speed of the crystal oscillator during detection, and cooperate with the two sets of card parts 110 to store the fixing frame 14 as a whole when the multimeter body 1 is not working.
[0025] like Figure 3 and 5As shown, the inner wall of the limit member 12 is fixed with two groups of springs 2; the end of the spring 2 is fixedly connected to the limit rod 21; the limit rod 21 is slidably arranged in the middle of the limit member 12; the end of the limit rod 21 is fixedly connected to a connecting plate 22; a bayonet 23 is fixedly connected to the top of the connecting plate 22; the bottom of the rotating shaft 13 is provided with a card slot 24 matched with the shape of the bayonet 23; the end of the connecting plate 22 is fixedly connected to a pressure plate 25; the middle part of the pressure plate 25 is concave; during operation, by arranging two groups of springs 2 in the middle of the limit member 12, when the staff needs to unfold the fixing frame 14 from the side wall of the multimeter body 1, the staff can press the middle part of the pressure plate 25 by hand, so that the connecting plate 22 as a whole will be separated from the card slot 24 after being subjected to a downward force, and then The staff can then rotate the fixing frame 14 so that after the fixing frame 14 is used for the designated work, the force pressing the top of the pressure plate 25 can be released, and the latch 23 can be again stuck in the slot 24 by means of the reaction force generated by the overall squeezing of the spring 2, and the overall working position of the fixing frame 14 can be fixed. This step, in conjunction with the latch 23 with a multi-deformable arrangement, can improve the fixing frame 14 during use. Since the rotating shaft 13 is difficult to be supported by the two sets of elastic cloths 17, the fixing frame 14 may shake or deviate in angle during operation, thereby improving the stability of the elastic cloth 17 during use. At the same time, the firmness of the fixing frame 14 when it is stored in the side wall of the multimeter body 1 can also be improved, thereby reducing the wear between the bracket 18 and the rubber barb 111 caused by repeated shaking of the fixing frame 14.
[0026] like Figure 4 As shown, the end of the counterweight block 16 is threadedly connected with a screw rod 3; the end of the screw rod 3 is rotatably connected with a slide 31; the slide 31 is slidably arranged on the outer wall of the counterweight block 16; the end of the slide 31 is fixedly connected with a fixed block 32, and the fixed block 32 is fixedly connected to the middle part of the elastic cloth 17; during operation, by arranging a screw rod 3 in the middle part of a group of counterweight blocks 16, when the staff uses the elastic cloth 17 to fix crystal oscillators of different widths or heights, the staff can use the work to rotate the end of the screw rod 3, and during the movement of the screw rod 3, the slide 31 will slide on the outer wall of the counterweight block 16, and pull the fixed block 32 to move synchronously, and complete the adjustment of the tightness or looseness of the elastic cloth 17. This step, in conjunction with the fixed block 32, can further enhance the flexibility of the elastic cloth 17 in fixing the crystal oscillator, and reduce the problem of difficulty in fixing the position of the crystal oscillator due to the elastic cloth 17 being loose or tight between the two groups of counterweight blocks 16 when fixing crystal oscillators of different thicknesses.
[0027] like Figure 4As shown, two groups of support rods 4 are fixedly connected to the middle part of the slide 31; the ends of the support rods 4 are fixedly connected to a top plate 41; the top plate 41 is slidably arranged inside the counterweight block 16; during operation, two groups of support rods 4 are arranged in the middle part of the slide 31, so that when the slide 31 slides in the middle part of the counterweight block 16, it will synchronously drive the two groups of support rods 4 to move, and under the action of the pulling force of the top plate 41 movement, the top plate 41 will slide in the middle part of the counterweight block 16 and cover the inner groove in the middle part of the screw 3. This step cooperates with the setting of the top plate 41 to improve the problem that some areas of the screw 3 are exposed to the outside world, resulting in some impurities adhering to the inner groove of the screw 3, and reducing the resistance of the screw 3 when it rotates in the middle part of the counterweight block 16. The cooperation with the two groups of support rods 4 can improve the synchronization of the top plate 41 in covering the inner groove of the screw 3.
[0028] like Figure 2 and 4 As shown, the end of the clamping member 110 is rotatably connected with a rotating ball 5; a guide groove 51 is opened in the middle of the clamping hole 19; during operation, by providing the rotating ball 5 at the end of the clamping member 110, when the clamping member 110 is close to the clamping hole 19, the rotating ball 5 will rotate and contact the inner wall of the inclined guide groove 51, and this step cooperates with the rotating rotating ball 5 to guide the clamping member 110 to be stuck in the clamping hole 19, thereby reducing the problem of bending of the clamping member 110 after long-term operation, which makes it difficult to be stuck in the clamping hole 19.
[0029] like Figure 5 As shown, a plurality of groups of reinforcement blocks 6 are fixedly connected to the bottom of the counterweight block 16, and the plurality of reinforcement blocks 6 are arranged in a linear array at the bottom of the counterweight block 16; during operation, by arranging a plurality of reinforcement blocks 6 at the bottom of the counterweight block 16, when the two groups of counterweight blocks 16 are close to the desktop or the ground, the raised reinforcement blocks 6 will reinforce the position of the counterweight blocks 16, and this step cooperates with the arranged reinforcement blocks 6 to enhance the grip of the counterweight block 16 during use, and further enhance the stability of the counterweight block 16 during operation.
[0030] like Figure 3 and 5 As shown, a friction pad 7 is fixedly connected to the top of the pressing plate 25; during operation, a friction pad 7 is provided in the middle of the recessed pressing plate 25, so that when the staff presses the middle of the pressing plate 25, their hands will first contact the friction pad 7. This step cooperates with the friction pad 7 to reduce the problem of slipping caused by sweat on the hands of the staff during the pressing of the pressing plate 25.
[0031] Working principle: by placing the multimeter body 1 in the working area, and inserting two sets of probe bodies 11 in the middle of the multimeter body 1, after turning on the multimeter body 1, the crystal oscillator to be detected is detected, and by setting a limit piece 12 at the end of the multimeter body 1, the staff can then pull the top of the slide bar 15 to make the fixed frame 14 rotate with the rotating shaft 13 as the center of the circle, and before the fixed frame 14 rotates, the staff can place multiple crystal oscillators side by side at the end of the multimeter body 1, so that the rotating fixed frame 14 is close to the positions of multiple crystal oscillators, and then the slide bar 15 can be loosened, and after the downward gravity of the two sets of counterweights 16, the middle of the elastic cloth 17 can be directly in contact with the middle of the crystal oscillator, and the multiple crystal oscillators can be initially tested. The fixing frame 14 is squeezed and fixed in the first step. When the fixing frame 14 needs to be stored as a whole, the fixing frame 14 can be rotated in the opposite direction again, so that the bracket 18 set at the end of the fixing frame 14 will gradually approach the position of the two groups of clamps 110. After continuing to push the fixing frame 14, the clamps 110 and multiple rubber barbs 111 will be stuck on the inner wall of the clamping hole 19, and the position of the fixing frame 14 will be fixed. By setting two groups of springs 2 in the middle of the limiter 12, when the staff needs to unfold the fixing frame 14 from the side wall of the multimeter body 1, the staff can press the middle of the pressing plate 25 with their hands, so that the connecting plate 22 is separated from the card slot 24 after being subjected to the downward force as a whole. Then the staff can rotate the fixing frame 14 so that the fixing frame 14 After the designated work is performed, the force pressing the top of the pressure plate 25 can be released, and the reaction force generated by the overall squeezing of the spring 2 can be used to clamp the latch pin 23 in the slot 24 again, and the overall working position of the fixing frame 14 can be fixed. By providing a screw rod 3 in the middle of a set of counterweight blocks 16, when the staff uses the elastic cloth 17 to fix the crystal oscillator of different widths or heights, the staff can use the work to rotate the end of the screw rod 3, and during the movement of the screw rod 3, the slide 31 will slide on the outer wall of the counterweight block 16, and pull the fixed block 32 to move synchronously, and complete the adjustment of the tightness or looseness of the elastic cloth 17. By providing two sets of support rods 4 in the middle of the slide 31, the slide 31 can slide in the middle of the counterweight block 16. When sliding, the two groups of support rods 4 will be driven to move synchronously, and under the action of the pulling force of the top plate 41, the top plate 41 will slide in the middle of the counterweight block 16 and cover the inner groove in the middle of the screw rod 3. By providing a rotating ball 5 at the end of the clamp 110, when the clamp 110 is close to the clamp hole 19, the rotating ball 5 will rotate and contact the inner wall of the inclined guide groove 51. By providing a plurality of reinforcement blocks 6 at the bottom of the counterweight block 16, when the two groups of counterweight blocks 16 are close to the desktop or the ground, the raised reinforcement blocks 6 will reinforce the position of the counterweight block 16.
