[0051] The specific application of this embodiment 1 is:

[0052] When the two ends of the parking plate 3 to be tested are slidably inserted into the entire device, and after preliminary sliding and plugging positioning and further rolling and fitting positioning, first record the initial position indicated by the indicator needle 503 on the scale 406, and then repeatedly bend the upper surface of the parking plate 3 to be tested through the repeated oblique extension process of the pressing and stretching member 7 in the entire device. When the pressing and stretching member 7 is performing the pressing and bending operation inside the entire device, the displacement blocks 501 in the two displacement members 5 that are respectively slidably matched in the first guide groove 403 and the second guide groove 404 begin to approach each other step by step, and thereby simultaneously stretch the first return spring 405 connected and fixed to the inner walls of the first guide groove 403 and the second guide groove 404. After being bent to a certain angle, the pressing and stretching member 7 begins to reset inside the entire device, and the pressing and stretching member 7 and The fitting contact effect between the upper surfaces of the parking plate 3 to be tested disappears. At this time, the parking plate 3 to be tested drives the displacement blocks 501 in the two displacement members 5 to move away from each other in the first guide groove 403 and the second guide groove 404 respectively through its own elastic force and the elastic recovery force of the first return spring 405, until the positions of the displacement blocks 501 in the two displacement members 5 are finally determined and stop sliding, and this is repeated, and the value at this moment is recorded by the position indicated by the indicator needle 503 on the scale 406, and then by comparing with the initial value, it is determined whether the parking plate 3 to be tested has undergone irreversible bending deformation after being bent multiple times, and finally the durability of the parking plate 3 to be tested is determined according to the degree of deformation. The entire testing process is simple to operate and the durability of the tested parking plate 3 can be intuitively determined.

[0054] The specific application of this second embodiment is:

[0055] The two ends of the parking plate 3 to be detected are slidably inserted into the entire device, and after preliminary sliding and plugging positioning, the telescopic cylinder 603 is started to drive the second connecting flange 604 fixed at the telescopic end of the telescopic cylinder 603 to extend inside the device, so that the two groups of inclined pressure plates 705 symmetrically fixed at the bottom of the connecting plate 701 are synchronously extended and gradually approach the surface of the parking plate 3 to be detected after the preliminary positioning. When the two groups of inclined pressure plates 705 synchronously approach the surface of the parking plate 3 to be detected, the rectangular frame 526 is driven to press downward through the sliding cooperation between the downward pressing lever 703 and the rectangular frame 526, and thereby the U-shaped pressing arm 525 is synchronously pressed downward between the first pin shaft 523 and the second pin shaft 524, so that the first I-shaped slider 517 and the second I-shaped slider 517 are fixedly connected. The second return spring 518 between the first oblique groove 516 is stretched, and at the same time, the third return spring 522 fixedly connected between the second I-shaped slider 521 and the oblique groove 520 is compressed, thereby driving the L-shaped extension plates 527 arranged below the first pin shaft 523 on both sides of the first I-shaped slider 517 and the two L-shaped extension plates 527 to rotate through the rotating shaft to cooperate with the laminating roller 528 to slowly roll and fit with the upper surface of the parking plate 3 to be detected, so that the two sliding insertion ends of the parking plate 3 to be detected are further positioned through the rolling and fitting action of the laminating roller 528 and the upper surface of the parking plate 3 to be detected, so as to prevent the parking plate 3 to be detected that is slid and inserted into the device from being separated during the durability test, thereby avoiding the influence of the later test results;

[0056] When the laminating pressing roller 528 rolls and laps with the upper surface of the parking plate 3 to be tested, the pressing plate 702 fixed to the bottom of the connecting plate 701 gradually approaches the upper surface of the parking plate 3, and through the extension process of the telescopic cylinder 603, the central position of the parking plate 3 to be tested is slowly pressed and bent, and the pressing and bending operation is repeated for multiple times, and then the resetting effect of the parking plate 3 to be tested is observed, so as to achieve and realize the durability test of the parking plate 3 to be tested;

[0057] When it is necessary to perform durability test on the parking plates 3 to be tested of different lengths, the servo motor 510 is started to drive the main sprocket 511 fixed to its output shaft to rotate forward or reverse, so that the transmission chain 514 is transmitted, thereby driving the two slave sprockets 513 to synchronously rotate forward or reverse in the same direction, and then driving the two threaded rods 512 respectively fixed at one end of the two slave sprockets 513 to synchronously rotate forward or reverse on the T-shaped slider 504, so that the T-shaped block 507 is finally moved between the T-shaped slot 505 and the slide slot 506, and the movement of the T-shaped block 507 between the T-shaped slot 505 and the slide slot 506 changes the direction of the two T-shaped blocks 507. The relative spacing between the two T-shaped blocks 507 can be adjusted to accommodate the parking plates 3 to be tested of different lengths, so as to facilitate the durability testing of the parking plates 3 to be tested of different lengths in the later stage (when the durability testing of the parking plates 3 to be tested of different lengths is carried out, during the process of adjusting the relative spacing between the two T-shaped blocks 507, the pressing lever 703 is always located inside the rectangular frame 526, and the position of the pressing lever 703 inside the rectangular frame 526 will change with the change of the relative spacing between the two T-shaped blocks 507, but the changing process is always located inside the rectangular frame 526, and the length of the rectangular frame 526 is applicable to the position change of the pressing lever 703, and its length is not the length of the structure drawn in the figure).

[0058] For example 3, please refer to Figure 1-14 , the third embodiment of the present invention is improved on the basis of the first embodiment as follows. Specifically, a fitting bottom plate 605 that fits with one side of the first guide groove 403 is fixed to the inner wall of the L-shaped cover plate 601 near the bottom; a trapezoidal side plate 606 that fits with one side of the second guide groove 404 is fixed to the top of the L-shaped cover plate 601, and the bottom of the trapezoidal side plate 606 is chamfered; a rectangular plate 408 is fixed to the inner wall of the L-shaped support plate 402 near the top, and a plug-in groove 409 is provided through the top of the rectangular plate 408, and an inner side wall of the L-shaped support plate 402 is located below the rectangular plate 408 and slides through the device A plurality of resistance rods 410 are arranged, one end of which is located inside the L-shaped support plate 402 in a dome-shaped arrangement; a plurality of resistance rods 410, one end of which is located on the outer wall of the L-shaped support plate 402, are commonly fixed with a movable plate 411, a U-shaped handle 412 is fixed on one side of the movable plate 411, and a plurality of elastic springs 413 are fixed between one side of the movable plate 411 and an outer side surface of the L-shaped support plate 402, which are respectively sleeved on the side surfaces of the plurality of resistance rods 410; a plurality of plug holes 607 are provided on one side of the trapezoidal side plate 606, which are located above the mounting plate, and the plug holes 607 are plugged in with the resistance rods 410.

[0059] The specific application of the third embodiment is as follows: before the device performs durability testing on the parking plate 3, the mounting plate 401 is first fixed to the to-be-tested station by external bolts, and then the to-be-tested parking plate 3 is slidably inserted into the interior of the entire device, so as to perform preliminary positioning and fixing, so as to perform durability testing later;

[0060] After the parking plate 3 to be tested is initially slid and plugged into position, the L-shaped cover plate 601 hingedly matched on the L-shaped support plate 402 is hingedly rotated, so that the trapezoidal side plate 606 fixed at the top inside the L-shaped cover plate 601 is gradually inserted into the plug-in groove 409 opened through the top of the rectangular plate 408, and thereby the elastic spring 413 fixedly connected between the movable plate 411 and the L-shaped support plate 402 is stretched through the mutual contact between the chamfered structure provided at the bottom of the trapezoidal side plate 606 and the dome structure provided at one end of the resistance rod 410, so that the plurality of resistance rods 410 are simultaneously gradually moved outward on an inner side wall of the L-shaped support plate 402, until the dome structure provided on the inner wall of the L-shaped support plate 402 and the plurality of plug-in holes 607 opened on one side of the trapezoidal side plate 606 are aligned with each other, and then the stretched elastic spring 413 begins to reset, driving the plurality of resistance rods 410 to simultaneously move in the L-shaped support plate 402. An inner wall of the support plate 402 gradually moves inward and is finally plugged into and fitted into a plurality of plug-in holes 607 (after a plurality of resistance rods 410 are respectively and simultaneously plugged into a plurality of plug-in holes 607, the fitting bottom plate 605 fixed near the bottom of the inner wall of the L-shaped cover plate 601 fits with the inlet end of the first guide groove 403, and at the same time, a side surface of the trapezoidal side plate 606 fixed at the top of the L-shaped cover plate 601 fits with the inlet end of the second guide groove 404, so that during the durability test, the inlet ends of the first guide groove 403 and the second guide groove 404 are in a closed state, preventing the sliding structure inside from slipping out and affecting the subsequent test results), thereby realizing a detachable connection between the L-shaped support plate 402 and the L-shaped cover plate 601 during the whole process, which is convenient for the staff to perform durability test on a plurality of parking plates 3 to be tested, thereby improving the staff's test efficiency.
