[0002] Shock absorbers are used to suppress the vibration caused by the rebound of springs after shock absorption and the impact from the road surface. They are widely used in automobiles to accelerate the attenuation of frame and body vibrations to improve the driving smoothness of the car. When passing through uneven roads, although the shock-absorbing springs can filter out the vibrations of the road surface, the shock absorbers need to be tested after production to check whether they can be used normally.

[0003] After the shock absorber is produced, it needs to be tested to pick out defective products and ensure the quality of the products. When testing traditional shock absorbers, the staff puts the shock absorber into water and observes whether the shock absorber is leaking by observing whether bubbles are generated after the shock absorber comes into contact with water. After the staff holds the shock absorber and puts it into the water, the hand holding the shock absorber will become weak when the staff conducts the test for a long time, which increases the difficulty of the work. In addition, when the shock absorber is put into water, small bubbles from the air may remain on the surface of the shock absorber, which can easily affect the test results. Therefore, a high-reliability shock absorber air tightness test device is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0018] 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.

[0019] The following is combined with Figure 1-Figure 3 The specific implementation modes of the present utility model are further described in detail.

[0020] The utility model includes a box body 1. In order to achieve the purpose of reducing the influence of bubbles on the detection accuracy, a box cover 2 is rotatably connected to the upper side of the box body 1, a movable plate 3 that can move up and down is provided on the lower side of the box cover 2, and two clamping frames 4 that can move forward and backward are provided on the lower side of the movable plate 3. Each clamping frame 4 is rotatably connected to a plurality of clamping plates 5. The clamping frames 4 and the clamping plates 5 cooperate with each other to form a shock absorber clamping structure. Two guide columns 6 are fixedly connected to the upper side of the movable plate 3. A plurality of vibration grooves 7 are respectively provided on the front and rear sides of each guide column 6. The vibration grooves 7 cooperate with the box body 1 to form a vibration structure for removing bubbles.

[0021] When in use, the box cover 2 can be first flipped up to the left to open, and then the shock absorber can be clamped and fixed by the clamping frame 4 and the clamping plate 5. After the detection liquid is added to the inside of the box body 1, the box cover 2 can be flipped to cooperate with the box body 1, and the shock absorber can be put into water after the movable plate 3 is lowered, and then it can be tested for air tightness. During the descent of the movable plate 3, under the mutual cooperation of the vibration groove 7 and the box body 1, each guide column 6 will vibrate, and then drive the movable plate 3 and the clamping frame 4 to vibrate, so that the movable plate 3 will vibrate and expel the bubbles on the surface of the shock absorber during the movement and descent, thereby reducing the probability that the gas attached to the surface of the shock absorber will affect the detection result.

[0022] Further, in order to facilitate the staff to clamp the shock absorber, a power shaft 8 is rotatably connected inside the movable plate 3, a rotatable threaded sleeve 9 is provided inside the movable plate 3, a first bevel gear 10 is coaxially fixedly connected to the middle of the threaded sleeve 9, and a second bevel gear 11 meshing with the first bevel gear 10 is fixedly connected to one end of the power shaft 8 close to the first bevel gear 10, and the power shaft 8 cooperates with the second bevel gear 11 and the first bevel gear 10 to form a rotatable structure of the threaded sleeve 9;

[0023] When in use, a worker can rotate the power shaft 8 , and the power shaft 8 drives the threaded sleeve 9 to rotate through the second bevel gear 11 and the first bevel gear 10 .

[0024] Furthermore, a threaded rod 12 is fixedly connected to the upper side of each clamping frame 4, and the threads inside the threaded sleeve 9 are symmetrical front and back and rotate in opposite directions. When the threaded sleeve 9 rotates, the two threaded rods 12 can be driven to move toward each other. Each threaded rod 12 is threadedly connected to the threaded sleeve 9. The rotation of the threaded sleeve 9 enables the two clamping frames 4 to form a mobile clamping structure. A guide plate 13 is fixedly connected to the left and right sides of each threaded rod 12, and each guide plate 13 is slidably connected to the movable plate 3.

[0025] During use, when the threaded sleeve 9 rotates, it can drive the two threaded rods 12 to move toward each other, thereby driving the clamping frame 4 and the clamping plate 5 to clamp the shock absorber.

[0026] Further, in order to adapt to the use of shock absorbers of different models, each of the clamping plates 5 is fixedly connected to a spring 14 on one side close to the corresponding clamping frame 4, and the lower side of each spring 14 is fixedly connected to the corresponding clamping frame 4. The spring 14 and the clamping frame 4 cooperate with each other to form a structure that can adapt to the use of shock absorbers of different models, so that the two clamping frames 4 drive the clamping plates 5 to clamp shock absorbers of different thicknesses;

[0027] When in use, the position where each of the clamping plates 5 is rotatably connected to the corresponding clamping frame 4 is located at the lower middle part of the clamping plate 5. When the two clamping frames 4 move toward each other to clamp the shock absorber, the clamping plate 5 will also rotate relative to the clamping frame 4, so that each of the clamping plates 5 can cooperate with each other to support the shock absorber upward. Each of the clamping plates 5 is arc-shaped, and the position where the clamping plate 5 is rotatably connected to the clamping frame 4 is located at the middle part of the clamping plate 5 on the side away from the moving plate 3. When the two clamping frames 4 are close to each other, Under the action of the spring 14, the side of each clamping plate 5 close to the movable plate 3 contacts the shock absorber before. As the clamping frame 4 continues to move, the clamping plate 5 rotates relative to the clamping frame 4. The clamping plate 5 cooperates with the clamping frame 4 to support the shock absorber and gradually clamp it. A limiting protrusion is provided on the side of each clamping frame 4 close to the movable plate 3 corresponding to the position of each clamping plate 5, so that each clamping plate 5 cannot rotate anymore after rotating to a certain angle relative to the clamping frame 4 during the clamping process, which is convenient for clamping the shock absorber.

[0028] Further, in order to facilitate the staff to perform the detection operation, an electric telescopic rod 15 is fixedly connected to the middle part of the box cover 2. The electric telescopic rod 15 is a prior art and will not be described in detail here. The output end of the electric telescopic rod 15 is fixedly connected to the movable plate 3. Two vibration blocks 16 adapted to the vibration groove 7 are provided on the upper side of the box cover 2. The vibration blocks 16 cooperate with the vibration groove 7 to form a structure that the movable plate 3 vibrates when it moves up and down. The vibration blocks 16 are fixedly connected to the box cover 2. The side of each of the vibration blocks 16 close to the vibration groove 7 is made of plastic material and has a certain elasticity. When the vibration blocks 16 cooperate with the guide column 6, each vibration block 16 is in a compressed state. As the guide column 6 moves under the drive of the electric telescopic rod 15, the vibration blocks 16 are matched with the corresponding vibration groove 7 in turn. When the two cooperate, the deformation is restored under the elastic action of the vibration blocks 16 themselves, and the vibration groove 7 is impacted, thereby causing the movable plate to vibrate.

[0029] When in use, the electric telescopic rod 15 can drive the movable plate 3 to move up and down, thereby enabling the vibration block 16 to move relative to the vibration groove 7. When the vibration block 16 passes through different vibration grooves 7, the guide column 6 will vibrate.

[0030] When the utility model is used, the box cover 2 can be first flipped up to the left and opened, and then the shock absorber can be clamped and fixed by the clamping frame 4 and the clamping plate 5. When the two clamping frames 4 move toward each other to clamp the shock absorber, the clamping plate 5 will also rotate relative to the clamping frame 4. At this time, each spring 14 is in a compressed state, so that each clamping plate 5 can cooperate with each other to support the shock absorber upward. After adding the detection liquid to the inside of the box body 1, the box cover 2 can be flipped to cooperate with the box body 1, and the shock absorber can be put into water after the movable plate 3 is lowered, and then it can be tested for air tightness. During the descent of the movable plate 3, under the mutual cooperation of the vibration groove 7 and the box body 1, each guide column 6 will vibrate, thereby driving the movable plate 3 and the clamping frame 4 to vibrate, so that the movable plate 3 will vibrate and expel the bubbles on the surface of the shock absorber during the movement and descent, thereby reducing the probability that the gas attached to the surface of the shock absorber will affect the detection result.

[0031] The utility model has a novel structure, ingenious conception, and simple and convenient operation. Through the design, the purpose of reducing the influence of bubbles on detection accuracy is effectively achieved, which is convenient for staff to clamp the shock absorber, so that the device can be adapted to the use of shock absorbers of different models, and it is convenient for staff to perform detection operations.
