The push-pull component 13 is pivotally connected to the middle of the connecting plate 17. The push-pull component 13 has a resisting end 1311 and a connecting end 1312 away from the resisting end 1311. The connecting end 1312 is connected to the raised section 110 through the elastic member 14. The driving mechanism is in transmission connection with the push-pull component 13 to drive the resisting end 1311 to convert the movement between a first position where it presses the drawer push-pull surface 31 of the push-pull drawer 30 and a second position where the resisting end 1311 disengages from the drawer push-pull surface 31. When the resisting end 1311 of the push-pull component 13 is converted from the first position to the second position, the push-pull drawer 30 automatically pops out.

[0033] In this embodiment, the device drives the push-pull component 13 to move between the first position and the second position through the driving mechanism, and at the same time utilizes the lever principle to enable the resisting end 1311 of the push-pull component 13 to automatically press the push-pull drawer 30 and automatically close the push-pull drawer 30, so as to simulate the popping out and closing actions of the actual push-pull drawer 30, thereby achieving the test of the durability performance of the guide rail of the push-pull drawer 30. In addition, the first fixing seat 11, the second fixing seat 12, the push-pull component 13 and the elastic member 14 of the device adopt a split structure, which has the characteristics of quick disassembly and assembly, reusable, etc., and can be used instead of a durability testing machine, which is beneficial to reducing the testing cost.

[0034] As a preferred embodiment, the driving mechanism includes a driving unit 15 and a traction line 16. Two ends of the traction line 16 are respectively connected to the output end of the driving unit 15 and the connection end 1312. The driving unit 15 can pull the abutting end 1311 from the first position to the second position through the traction line 16. In this way, not only can the abutting end 1311 be driven to reciprocate between the first position and the second position by the combination of the pulling force of the driving mechanism and the compression elastic member 14, but also the magnitude of the pressing and elastic force exerted by the abutting end 1311 on the drawer can be controlled.

[0035] As a preferred embodiment, a first guiding portion 18 is provided on the first fixed seat 11, and a second guiding portion 19 is provided on the second fixed seat 12. One end of the traction line 16 is connected to the output end of the driving unit 15, and the other end is sequentially wound around the second guiding portion 19 and the first guiding portion 18 and then connected to the connection end 1312.

[0036] In this embodiment, the first guiding portion 18 and the second guiding portion 19 play a guiding role in the movement of the traction line 16, and the transmission effect is better. Specifically, referring to Figure 6 , the structures of the first guiding portion 18 and the second guiding portion 19 in this embodiment can be rotating shafts.

[0037] As a preferred embodiment, the driving unit 15 is a cylinder, and a traction head 151 connected to the traction line 16 is provided at the end of the piston rod of the cylinder. By providing the traction head 151, on the one hand, it is convenient to connect the traction line 16, and on the other hand, the action of actually pressing and bouncing the drawer 30 can be simulated by pressing the pressing and elastic surface of the drawer with the traction head 151.

[0038] As a preferred embodiment, the connecting plate 17 is provided with a guiding channel 171, and the traction head 151 is provided with a vertically arranged guiding plate (not shown in the figure). The upper end of the guiding plate extends into the guiding channel 171. One end of the traction line 16 is connected to the traction head 151, and the other end passes through the guiding plate movably and then is connected to the connection end 1312 of the pressing and bouncing assembly 13. Through the cooperation of the guiding plate and the guiding channel 171, a good limiting and guiding effect on the traction line 16 is achieved.

[0039] As a preferred embodiment, the traction line 16 is a traction belt.

[0040] As a preferred embodiment, the pressing and bouncing assembly 13 includes two parallel pressing and bouncing plate members 131 and a connecting block 132 connecting the two pressing and bouncing plate members 131. The middle parts of the two pressing and bouncing plate members 131 are pivotally connected to the connecting plate 17 and are both located outside the connecting plate 17. The pressing and bouncing assembly 13 adopting such a technical solution not only has a simple structure but also is convenient for disassembly.

[0041] As a preferred embodiment, one end of the push - button plate member 131 away from the connection block 132 forms the abutting end 1311, and the abutting end 1311 is provided with a semi - circular arc structure. The abutting end 1311 is in a semi - circular arc structure to avoid damaging the push - button surface 31 of the drawer.

[0042] As a preferred embodiment, it further includes a controller, and the controller is electrically connected to the driving mechanism to control the operation of the driving mechanism. Adopting such a technical solution not only has a high degree of automation but also can ensure the accuracy of the alternating operation of pushing - button and closing.

[0043] The present invention also provides a method for testing the durability of a push - button drawer. Using the above - mentioned push - button drawer durability testing device 10, the testing method includes the following steps:

[0044] S1. Assemble the push - button drawer 30 to be tested with the durability testing device 10 so that the abutting end 1311 of the push - button assembly 13 can abut against the push - button surface of the push - button drawer 30 to be tested;

[0045] S2. The driving unit 15 pulls the traction line 16 backward, the traction line 16 synchronously pulls down the elastic member 14, drives the connection end 1312 of the push - button assembly 13 to descend, so as to drive the abutting end 1311 of the push - button assembly 13 to move from the first position of pressing the drawer push - button surface 31 to the second position where the abutting end 1311 of the push - button assembly 13 disengages from the drawer push - button surface 31, and the push - button drawer 30 automatically pops out;

[0046] S3. The driving unit 15 pushes the drawer forward, the traction line 16 automatically folds and retracts into the push - button drawer 30, the elastic member 14 drives the connection end 1312 of the push - button assembly 13 to rise, so as to drive the abutting end 1311 of the push - button assembly 13 to move from the second position of disengaging from the drawer push - button surface 31 to the first position of pressing the drawer push - button surface 31, and automatically closes the push - button drawer 30;

[0047] S4. Repeat step S2 and step S3 to complete the durability test of the push - button drawer 30.

[0048] In this embodiment, in step S1, the first fixed seat 11 is fixed on the fixed tabletop 20 with screws, and the height - increasing section 110 is connected with screws. The second fixed seat 12 is fixed on the test cabinet body with screws, and the connecting plate 17 is lapped between the first fixed seat 11 and the second fixed seat 12. The push - button assembly 13 is connected to the height - increasing section 110 with the elastic member 14, and the traction line 16 is bound between the driving unit 15 and the push - button assembly 13. Then, the reserved length of the traction line 16 is placed in the drawer guide rail, and the extra reserved length is made to automatically fold and overlap together by the action of gravity to complete the assembly of the push - button drawer 30 to be tested and the durability testing device 10.

[0049] In steps S2 and S3, the drive unit 15 pulls the pull wire 16 backward, which simultaneously pulls down the elastic member 14 until it is straightened and taut, driving the connection end 1312 of the push-spring assembly 13 downward. Leveraging the principle of leverage, the abutting end 1311 of the push-spring assembly 13 automatically rises, causing the push-spring drawer 30 to open by inertia. In step 3, the drive unit 15 moves forward, relaxing the pull wire 16. Gravity causes the extended pull wire 16 to automatically fold together and return to its original position within the drawer. Simultaneously, the elastic member 14 relaxes, automatically lifting the connection end 1312 of the push-spring assembly 13. Leveraging the principle of leverage, the abutting end 1311 of the push-spring assembly 13 descends, contacting the drawer spring surface 31 of the push-spring drawer 30 and generating a closing force, reclosing the push-spring drawer 30. By repeating steps S2 and S3, the push-spring drawer 30 is reciprocally closed, achieving the durability test of the guide rails of the push-spring drawer 30.

[0050] The present invention utilizes a push-to-pop drawer durability testing device 10 to simulate human use of a push-to-pop drawer 30 times of opening and closing, thereby meeting the drawer guide rail industry standard of 40,000 openings and closings. According to the QB / T2454-2013 standard, a push-to-pop drawer should meet the following requirements:

[0051] a) All components or connectors should not be broken or damaged:
