Description

Technical Field

[0001] The invention belongs to the technical field of vibration testing, and in particular relates to a batch vibration testing device for spring buckles. Background Art

[0002] The main body of the spring buckle is composed of two circular features of different sizes. Since the spring buckle is composed of multiple independent parts such as springs and hinged shafts, the main failures during its use often occur in the elastic opening and closing part that needs to rotate back and forth. Therefore, for the spring buckles that have been produced, it is often necessary to sample and conduct aging tests to determine their durability and qualification.

[0003] Most of the current vibration testing devices conduct vibration and opening and closing tests of the elastic opening and closing part as two independent test items respectively; the vibration test mainly fixes the spring buckle bodies one by one on the vibration base through a clamp, and then judges the looseness of the connection part of the spring buckle through the high-frequency vibration of the base; and the opening and closing test of the elastic opening and closing part is to perform aging test directly by reciprocating the elastic opening and closing part.

[0004] The above test deviates greatly from the actual scenario, because the spring buckle is generally connected to a flexible rope or wire, and the impact often occurs at the same time as the elastic opening and closing part rotates and opens. Therefore, testing the vibration impact and the opening and closing of the elastic opening and closing part together can not only simplify the test steps, shorten the test time, and reduce the test cost, but also because the test is more in line with the actual usage scenario, the test results can better reflect the product life. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes a batch vibration testing device for a spring buckle that controls the reciprocating opening and closing of an elastic opening and closing part by means of reciprocating impact; in order to simplify the structure, the present invention simultaneously drives the workpiece direction adjustment and vibration test of the workpiece direction adjustment mechanism through a reciprocating vibration component, but in the process of workpiece direction adjustment, the blocking bracket needs to slide back and forth with the L-shaped slide, otherwise a collision will occur between the spring buckle body and the blocking bracket, affecting the direction adjustment of the spring buckle body; and in the process of vibration testing, the blocking bracket cannot slide back and forth with the L-shaped slide, otherwise a collision will not occur between the spring buckle body and the blocking bracket, and the test cannot be performed; in order to overcome this technical contradiction, the present invention creatively proposes a workpiece direction adjustment mechanism and a self-locking blocking mechanism, through an opening and closing support component that can change its own width, on the one hand, the spring buckle body can automatically adjust its direction according to the different positions of the center of gravity, and on the other hand, it can automatically control the linkage of the blocking bracket through its own expansion and contraction.

[0006] The technical solution adopted by the present invention is as follows: The present invention proposes a batch vibration testing device for spring buckles, including a workpiece direction adjustment mechanism, an equidistant clamping mechanism, a self-locking blocking mechanism and a base plate mechanism, wherein the workpiece direction adjustment mechanism is arranged on the base plate mechanism, the equidistant clamping mechanism is arranged on the workpiece direction adjustment mechanism, the self-locking blocking mechanism is arranged on the base plate mechanism, and the self-locking blocking mechanism and the equidistant clamping mechanism are alternately distributed.

[0007] Furthermore, the workpiece direction adjustment mechanism includes an L-shaped slide, an opening and closing support assembly, a spring buckle body and a clamping assembly, the L-shaped slide is arranged on the base plate mechanism, the opening and closing support assembly is arranged on the L-shaped slide, the spring buckle body array is arranged on the opening and closing support assembly, and the clamping assembly is arranged on both sides of the L-shaped slide.

[0008] Through the automatic opening and closing of the workpiece direction adjustment mechanism, the locking and unlocking of the self-locking blocking mechanism can be controlled, thereby overcoming the technical contradiction that the self-locking blocking mechanism needs to follow the movement during the direction adjustment process (to avoid the collision between the blocking bracket and the spring buckle body) and the self-locking blocking mechanism needs relative movement during the vibration test (to ensure the collision between the blocking bracket and the spring buckle body).

[0009] Preferably, the opening and closing support assembly includes a side sliding groove, an intermediate fixed plate, an arc-shaped sliding plate and an opening spring, the side sliding groove is fixed to the inner side of the L-shaped sliding seat, the intermediate fixed plate is fixed to the middle position of the side sliding groove, guide round rods are arrayed on both sides of the intermediate fixed plate, guide round sleeves corresponding to the guide round rods are arrayed on the arc-shaped sliding plate, the guide round sleeves are snap-fitted and slidably arranged on the guide round rods, the opening spring is sleeved on the outside of the guide round rods and the guide round sleeves, and the opening spring is arranged between the intermediate fixed plate and the arc-shaped sliding plate.

[0010] When the opening and closing support assembly is popped open, it is too wide to enter the small circle of the spring buckle body. At this time, through the design of the center of gravity position of the spring buckle body, all the spring buckle bodies can be adjusted to a state with the large circle facing up and the small circle facing down during the vibration process. After the opening and closing support assembly tightens itself and enters the small circle, on the one hand, it can fix the position of the small circle, and on the other hand, it can unlock the self-locking blocking mechanism through the clamping assembly when itself is tightened.

[0011] As a further preferred embodiment of the present invention, an elastic opening and closing portion is provided on the spring buckle body, and the spring buckle body is arranged on an opening and closing support assembly. The clamping assembly includes a clamp plate 1 and a clamp plate 2, and the clamp plate 1 and the clamp plate 2 are snap-fitted and slidably arranged in an L-shaped sliding seat and a side sliding groove, and the clamp plate 1 and the clamp plate 2 are respectively fixedly connected to the ends of two arc-shaped sliding plates.

[0012] During the movement of the first clamping plate and the second clamping plate following the arc-shaped sliding plate, clamping and fixing as well as releasing and unlocking of the clamping plate can be achieved.

[0013] Furthermore, the equidistant clamping mechanism includes a fixed seat lifting assembly, a fixed seat driving assembly, and a fixed seat limiting assembly. The fixed seat lifting assembly is slidably disposed on the L-shaped sliding seat, the fixed seat driving assembly is disposed on the fixed seat lifting assembly, and the fixed seat limiting assembly is disposed on the L-shaped sliding seat.

[0014] By the sequential upward movement of the equidistant clamping mechanism, on the one hand, the spring buckle body can be clamped and fixed from the bottom, so that the spring buckle body remains fastened during subsequent vibration tests. On the other hand, through the cooperation of the long slope portion and the short slope portion, the spring buckle bodies can be separated at uniform intervals, so that the spring buckle bodies in each group will not collide with each other during the vibration test.

[0015] Preferably, the fixed seat lifting assembly includes a buckle fixed seat, an anti-rotation plug plate, and a fixed seat return spring. A bottom guide rod is provided at the bottom of the buckle fixed seat. The buckle fixed seat is slidably clamped on the L-shaped sliding seat through the bottom guide rod. The buckle fixed seat is also provided with a long slope portion and a short slope portion. The width of the short slope portion is smaller than the thickness of the spring buckle body. The anti-rotation plug plate is clamped between the long slope portion and the short slope portion. Through the limitation of the anti-rotation plug plate, deflection of the spring buckle body during the test can be avoided. The fixed seat return spring is disposed between the buckle fixed seat and the L-shaped sliding seat.

[0016] As a further preference of the present invention, the fixed seat driving assembly includes a slope sliding plate and a driving ejector rod. The slope sliding plate is fixedly connected to the bottom of the buckle fixed seat. The driving ejector rod is slidably clamped on the side surface of the L-shaped sliding seat. A slope block matching the slope sliding plate is provided on the driving ejector rod. The slope block is slidably clamped on the L-shaped sliding seat.

[0017] As a further preference of the present invention, the fixed seat limiting assembly includes a limit block sliding bracket, a slope limit block body, a limit block return spring, and a release handle. The limit block sliding bracket is fixedly connected to the L-shaped sliding seat. A limit block guide rod is provided on the slope limit block body. The slope limit block body is slidably clamped on the limit block sliding bracket through the limit block guide rod. The limit block return spring is disposed between the slope limit block body and the limit block sliding bracket. The release handle is fixedly connected to the end of the limit block sliding bracket.

[0018] The position of the latch fixing base can be limited by the fixing base limiting component, so that the latch fixing base can be maintained at the current position after being pushed to the top, thereby continuously clamping and fixing the spring buckle body. After the test is completed, the limit of the latch fixing base can be released in batches by releasing the handle, so that each group of latch fixing bases can be reset under the elastic force of the fixing base return spring.

[0019] Further, the self-locking baffle mechanism includes a fixed side plate and a self-locking baffle component. The fixed side plate is provided with a side plate chute and a spring mounting plate. The self-locking baffle component includes a baffle bracket, a baffle spring and a cantilever extension rod. The baffle bracket is clamped and slidably arranged in the side plate chute. The baffle spring is arranged between the spring mounting plate and the baffle bracket. The cantilever extension rod is fixedly connected to both ends of the baffle bracket. A clamping plate is arranged at the end of the cantilever extension rod, and the clamping plate is located between the first clamping plate and the second clamping plate.

[0020] Further, the bottom plate mechanism includes a main body bottom plate and a reciprocating vibration component. The fixed side plate is fixedly connected to the main body bottom plate. The main body bottom plate is provided with a sliding guide rail, and a main sliding plate is slidably arranged on the sliding guide rail. The L-shaped sliding seat is arranged on the main sliding plate.

[0021] Preferably, the reciprocating vibration component includes a vibration motor, a reciprocating turntable and a reciprocating connecting rod. The vibration motor is arranged on the main body bottom plate. The reciprocating turntable is arranged on the output shaft of the vibration motor. One end of the reciprocating connecting rod is hinged to one side of the reciprocating turntable, and the other end of the reciprocating connecting rod is hinged to the L-shaped sliding seat.

[0022] Through the driving module of the reciprocating vibration component, the L-shaped sliding seat can be made to slide reciprocally. Under the driving action of the reciprocating vibration component, when the bottom of the spring buckle body is not fixed, the direction of the spring buckle body can be automatically adjusted by the reciprocating sliding of the L-shaped sliding seat, so that the small ring part of the spring buckle body faces downward; after the bottom of the spring buckle body is fixed, the reciprocating sliding of the L-shaped sliding seat can cause relative sliding between the baffle bracket and the L-shaped sliding seat, so that the baffle bracket continuously impacts and opens and closes the elastic opening and closing part, thereby realizing the vibration test of the spring buckle body.

[0023] The beneficial effects obtained by the present invention adopting the above structure are as follows: (1) Through the automatic opening and closing of the workpiece direction adjustment mechanism, the locking and unlocking of the self-locking baffle mechanism can be controlled, thereby overcoming the technical contradiction that the self-locking baffle mechanism needs to move along with it during the process of adjusting the direction (to avoid the impact between the baffle bracket and the spring buckle body), and the self-locking baffle mechanism needs relative movement during the vibration test (to ensure the impact between the baffle bracket and the spring buckle body).

[0024] (2) When the opening and closing support component pops open, its width is too large to enter the small ring of the spring buckle body. At this time, through the design of the center of gravity position of the spring buckle body, all spring buckle bodies can be adjusted to the state where the large ring is facing up and the small ring is facing down during the vibration process. After the opening and closing support component tightens itself and enters the small ring, on the one hand, it can fix the position of the small ring, and on the other hand, it can unlock the self-locking blocking mechanism through the clamping component when it tightens itself.

[0025] (3) Through the sequential rise of the equidistant clamping mechanism, on the one hand, it can engage and fix the spring buckle body from the bottom, so that the spring buckle body remains fastened during the subsequent vibration test. On the other hand, through the cooperation of the long slope part and the short slope part, the spring buckle bodies can be separated at equal intervals, so that the groups of spring buckle bodies will not collide with each other during the vibration test.

[0026] (4) The fixed seat limiting component can limit the position of the lock buckle fixed seat, so that the lock buckle fixed seat can stay in the current position after being pushed to the top, thereby continuously clamping and fixing the spring buckle body. After the test is completed, the limit of the lock buckle fixed seat can be released in batches through the release handle, so that each group of lock buckle fixed seats can be reset under the elastic force of the fixed seat return spring.

[0027] (5) Through the reciprocating vibration component, which is a driving module, the L-shaped sliding seat can slide reciprocally. Under the driving action of the reciprocating vibration component, when the bottom of the spring buckle body is not fixed, the direction of the spring buckle body can be automatically adjusted through the reciprocating sliding of the L-shaped sliding seat, so that the small ring part of the spring buckle body faces down. After the bottom of the spring buckle body is fixed, the reciprocating sliding of the L-shaped sliding seat can cause relative sliding between the blocking bracket and the L-shaped sliding seat, so that the elastic opening and closing part can be continuously impacted and opened and closed through the blocking bracket, thereby realizing the vibration test of the spring buckle body.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0032] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0033] As Figures 1 to 11 shown, the present invention proposes a batch vibration test device for spring buckles, including a workpiece direction adjustment mechanism 1, an equidistant clamping mechanism 2, a self-locking baffle mechanism 3 and a bottom plate mechanism 4. The workpiece direction adjustment mechanism 1 is arranged on the bottom plate mechanism 4, the equidistant clamping mechanism 2 is arranged on the workpiece direction adjustment mechanism 1, the self-locking baffle mechanism 3 is arranged on the bottom plate mechanism 4, and the self-locking baffle mechanism 3 and the equidistant clamping mechanism 2 are alternately distributed.

[0034] The bottom plate mechanism 4 includes a main bottom plate 43 and a reciprocating vibration assembly 44. The fixed side plate 35 is fixedly connected to the main bottom plate 43. A sliding guide rail 45 is arranged on the main bottom plate 43, and a main sliding plate 49 is slidably arranged on the sliding guide rail 45. An L-shaped sliding seat 5 is arranged on the main sliding plate 49.

[0035] The reciprocating vibration assembly 44 includes a vibration motor 46, a reciprocating turntable 47 and a reciprocating connecting rod 48. The vibration motor 46 is arranged on the main bottom plate 43, the reciprocating turntable 47 is arranged on the output shaft of the vibration motor 46, one end of the reciprocating connecting rod 48 is hinged to one side of the reciprocating turntable 47, and the other end of the reciprocating connecting rod 48 is hinged to the L-shaped sliding seat 5.

[0036] Through the driving module of the reciprocating vibration assembly 44, the L-shaped sliding seat 5 can be made to slide reciprocally. Under the driving action of the reciprocating vibration assembly 44, when the bottom of the spring buckle body 7 is not fixed, the direction of the spring buckle body 7 can be automatically adjusted by the reciprocating sliding of the L-shaped sliding seat 5, so that the small ring part of the spring buckle body 7 faces downward; and after the bottom of the spring buckle body 7 is fixed, the reciprocating sliding of the L-shaped sliding seat 5 can cause relative sliding between the baffle bracket 39 and the L-shaped sliding seat 5, so as to continuously impact and open and close the elastic opening and closing part 13 through the baffle bracket 39, thereby realizing the vibration test of the spring buckle body 7.

[0037] The self-locking blocking mechanism 3 includes a fixed side plate 35 and a self-locking blocking component 36. The fixed side plate 35 is provided with a side plate sliding groove 37 and a spring mounting plate 38. The self-locking blocking component 36 includes a blocking bracket 39, a blocking spring 40, and a cantilever extension rod 41. The blocking bracket 39 is snap-fitted and slidably arranged in the side plate sliding groove 37. The blocking spring 40 is arranged between the spring mounting plate 38 and the blocking bracket 39. The cantilever extension rod 41 is fixedly connected to both ends of the blocking bracket 39. A clamping plate 42 is provided at the end of the cantilever extension rod 41. The clamping plate 42 is located between the first clamping plate 14 and the second clamping plate 15.

[0038] The workpiece direction adjustment mechanism 1 includes an L-shaped sliding seat 5, an opening and closing support component 6, a spring buckle body 7, and a clamping component 8. The L-shaped sliding seat 5 is arranged on the bottom plate mechanism 4. The opening and closing support component 6 is arranged on the L-shaped sliding seat 5. The spring buckle bodies 7 are arranged in an array on the opening and closing support component 6. The clamping component 8 is arranged on both sides of the L-shaped sliding seat 5.

[0039] Through the automatic opening and closing of the workpiece direction adjustment mechanism 1, the locking and unlocking of the self-locking blocking mechanism 3 can be controlled, thereby overcoming the technical contradiction that the self-locking blocking mechanism 3 needs to move along during the process of adjusting the direction (to avoid the impact between the blocking bracket 39 and the spring buckle body 7), and the self-locking blocking mechanism 3 needs relative movement during the vibration test (to ensure the impact between the blocking bracket 39 and the spring buckle body 7).

[0040] The opening and closing support component 6 includes a side sliding groove 9, a middle fixing plate 10, an arc-shaped sliding plate 11, and a spreading spring 12. The side sliding groove 9 is fixedly connected to the inner side of the L-shaped sliding seat 5. The middle fixing plate 10 is fixedly connected to the middle position of the side sliding groove 9. Guide round rods 16 are arranged in an array on both sides of the middle fixing plate 10. Guide round sleeves 17 corresponding to the guide round rods 16 are arranged in an array on the arc-shaped sliding plate 11. The guide round sleeves 17 are snap-fitted and slidably arranged on the guide round rods 16. The spreading spring 12 is sleeved outside the guide round rods 16 and the guide round sleeves 17. The spreading spring 12 is arranged between the middle fixing plate 10 and the arc-shaped sliding plate 11.

[0041] When the opening and closing support component 6 is sprung open, its width is relatively large and it cannot enter the small ring of the spring buckle body 7. At this time, through the design of the center of gravity position of the spring buckle body 7, all the spring buckle bodies 7 can be adjusted to the state where the large ring is facing up and the small ring is facing down during the vibration process. After the opening and closing support component 6 contracts itself and enters the small ring, on the one hand, it can fix the position of the small ring, and on the other hand, it can unlock the self-locking blocking mechanism 3 through the clamping component 8 when it contracts itself.

[0042] The spring buckle body 7 is provided with an elastic opening and closing part 13. The spring buckle body 7 is arranged on the opening and closing support assembly 6. The clamping assembly 8 includes a first clamping plate 14 and a second clamping plate 15. The first clamping plate 14 and the second clamping plate 15 are clamped and slidably arranged in the L-shaped sliding seat 5 and the side sliding groove 9. The first clamping plate 14 and the second clamping plate 15 are respectively fixedly connected to the ends of two arc-shaped sliding plates 11.

[0043] During the process of the first clamping plate 14 and the second clamping plate 15 following the arc-shaped sliding plate 11, the clamping and fixing and release and unlocking of the clamping plate 42 can be realized.

[0044] The equidistant clamping mechanism 2 includes a fixed seat lifting assembly 18, a fixed seat driving assembly 19 and a fixed seat limiting assembly 20. The fixed seat lifting assembly 18 is slidably arranged on the L-shaped sliding seat 5. The fixed seat driving assembly 19 is arranged on the fixed seat lifting assembly 18. The fixed seat limiting assembly 20 is arranged on the L-shaped sliding seat 5.

[0045] Through the sequential rising of the equidistant clamping mechanism 2, on the one hand, the spring buckle body 7 can be clamped and fixed from the bottom, so that the spring buckle body 7 remains fastened during the subsequent vibration test. On the other hand, through the cooperation of the long slope part 30 and the short slope part 31, the spring buckle bodies 7 can be separated at uniform intervals, so that the groups of spring buckle bodies 7 will not collide with each other during the vibration test.

[0046] The fixed seat lifting assembly 18 includes a lock buckle fixed seat 21, an anti-rotation plug plate 22 and a fixed seat return spring 23. The bottom of the lock buckle fixed seat 21 is provided with a bottom guide rod 32. The lock buckle fixed seat 21 is clamped and slidably arranged on the L-shaped sliding seat 5 through the bottom guide rod 32. The lock buckle fixed seat 21 is also provided with a long slope part 30 and a short slope part 31. The width of the short slope part 31 is smaller than the thickness of the spring buckle body 7. The anti-rotation plug plate 22 is clamped between the long slope part 30 and the short slope part 31. Through the limitation of the anti-rotation plug plate 22, the deflection of the spring buckle body 7 during the test can be avoided. The fixed seat return spring 23 is arranged between the lock buckle fixed seat 21 and the L-shaped sliding seat 5.

[0047] The fixed seat driving assembly 19 includes a slope sliding plate 24 and a driving ejector rod 25. The slope sliding plate 24 is fixedly connected to the bottom of the lock buckle fixed seat 21. The driving ejector rod 25 is clamped and slidably arranged on the side of the L-shaped sliding seat 5. The driving ejector rod 25 is provided with a slope block 33 matching the slope sliding plate 24. The slope block 33 is clamped and slidably arranged on the L-shaped sliding seat 5.

[0048] The fixed seat limiting component 20 includes a limiting block sliding bracket 26, a ramp limiting block body 27, a limiting block return spring 28, and a release handle 29. The limiting block sliding bracket 26 is fixedly connected to the L-shaped sliding seat 5. The ramp limiting block body 27 is provided with a limiting block guide rod 34. The ramp limiting block body 27 is engaged and slidably arranged on the limiting block sliding bracket 26 through the limiting block guide rod 34. The limiting block return spring 28 is arranged between the ramp limiting block body 27 and the limiting block sliding bracket 26. The release handle 29 is fixedly connected to the end of the limiting block sliding bracket 26.

[0049] The position of the latch fixed seat 21 can be limited by the fixed seat limiting component 20, so that the latch fixed seat 21 can stay in the current position after being pushed to the top, thereby continuously clamping and fixing the spring latch body 7. After the test is completed, the limit of the latch fixed seat 21 can be released in batches through the release handle 29, so that each group of latch fixed seats 21 can be reset under the elastic force of the fixed seat return spring 23.

[0050] As Figure 12 shown, the spring latch body 7 is composed of a large ring part and a small ring part spliced together. The elastic opening and closing part 13 is located on the large ring part. When the spring latch body 7 is just installed on the opening and closing support component 6, the small ring part of the spring latch body 7 may face upward or downward. Since the opening and closing support component 6 in the unfolded state cannot enter the small ring part, the two dotted circles a and b in the figure represent the positions of the opening and closing support component 6 in the above two states of the spring latch body 7. Since the distances from the centers of the two dotted circles a and b to the center of gravity of the spring latch body 7 are different. Specifically, a is farther from the center of gravity of the spring latch body 7. When the small ring part of the spring latch body 7 faces downward, its own state is more stable. Therefore, when the L-shaped sliding seat 5 swings reciprocally, all the spring latch bodies 7 can automatically adjust to the direction with the small ring part facing downward.

[0051] In specific use, first, when the opening and closing support component 6 is in the open state, the user needs to batch set a specific number of spring latch bodies 7 on the opening and closing support component 6 through an external feeding device or a tooling fixture (since the elastic opening and closing part 13 can be rotated and opened, it can be directly buckled on). At this time, since the external feeding device does not distinguish the direction of the spring latch body 7, the small ring part of the spring latch body 7 just set on the opening and closing support component 6 may face upward or downward. When the spring latch body 7 is just installed on the opening and closing support component 6, the small ring part of the spring latch body 7 may face upward or downward. Since the opening and closing support component 6 in the unfolded state cannot enter the small ring part, Figure 12 the two dotted circles a and b in Subsequently, the vibration motor 46 is started. During the continuous rotation of the reciprocating turntable 47, the L-shaped sliding seat 5 can be reciprocally slid by the reciprocating connecting rod 48. Since the stability of the spring buckle body 7 is different in different directions, when the rotational speed of the vibration motor 46 is adjusted to an appropriate speed, it can be ensured that when the small ring portion of the spring buckle body 7 faces upward, the swing of the spring buckle body 7 can cause its own direction to rotate, while when the small ring portion of the spring buckle body 7 faces downward, the swing of the spring buckle body 7 cannot cause the spring buckle body 7 to rotate. After a period of vibration, all the spring buckle bodies 7 can be adjusted to the direction with the small ring portion facing downward.

[0052] In the above process, since the clamping plate 42 is clamped by the first clamping plate 14 and the second clamping plate 15, the sliding of the L-shaped sliding seat 5 will also drive the blocking bracket 39 to slide together, thus avoiding collision between the blocking bracket 39 and the spring buckle body 7.

[0053] After the vibration motor 46 is turned off, the driving ejector rod 25 is pushed towards the inside of the L-shaped sliding seat 5. Through the cooperation of the ramp block 33 and the ramp slide plate 24, each group of buckle fixing seats 21 can be sequentially lifted. When the buckle fixing seat 21 rises, the small ring portion at the bottom of the spring buckle body 7 will enter the buckle fixing seat 21, and the rising buckle fixing seat 21 will also push the entire spring buckle body 7 to rise. As the spring buckle body 7 rises, the arc-shaped sliding plate 11 will gradually approach the middle fixing plate 10 against the elastic force of the opening spring 12. During this process, the first clamping plate 14 and the second clamping plate 15 respectively move away from the clamping plate 42; On the other hand, since the opening and closing support assembly 6 is slightly inclined as a whole, after vibration, all the spring buckle bodies 7 will accumulate at the end where the ramp block 33 is located. The width of the short ramp portion 31 is smaller than the thickness of the spring buckle body 7. Therefore, when each buckle fixing seat 21 rises, only one spring buckle body 7 will be stuck in the gap between the long ramp portion 30 and the short ramp portion 31; At the same time, when the buckle fixing seat 21 rises to the top, the blocking of the buckle fixing seat 21 will be completed through the sliding of the ramp limiting block body 27, so that the buckle fixing seat 21 is maintained at the top limit position; When the ramp block 33 is pushed to the other end, all the spring buckle bodies 7 will be fixed, and all the buckle fixing seats 21 are maintained at the top limit position.

[0054] Then, the vibration motor 46 is started again, and the L-shaped sliding seat 5 vibrates again. At this time, since both the clamping plate one 14 and the clamping plate two 15 are far away from the clamping plate 42, during the reciprocating sliding of the L-shaped sliding seat 5, it will not drive the blocking bracket 39 to slide together. Therefore, the spring buckle body 7 fixed by clamping will collide with the blocking bracket 39; during the vibration test, on the one hand, the overall spring buckle body 7 is tested through the reciprocating movement of the L-shaped sliding seat 5, and on the other hand, through the collision between the blocking bracket 39 and the elastic opening and closing part 13 and the rotation of the elastic opening and closing part 13, the hinge part and the spring part of the elastic opening and closing part 13 are tested; During this process, although the blocking bracket 39 will have a small amount of displacement to avoid the elastic force of the blocking spring 40, since the spring force of the hinge part of the elastic opening and closing part 13 is small, it is still sufficient to test the spring buckle body 7 and the elastic opening and closing part 13.

[0055] After the test is completed, all the ramp limit block bodies 27 are synchronously pulled outwards by releasing the handle 29. At this time, all the buckle fixing seats 21 will reset under the elastic force of the fixing seat reset spring 23, and the clamping and fixing of the buckle fixing seats 21 will be released. Then, the spring buckle body 7 is removed and the degree of damage and the damage rate are counted.
