Fig. 1 and fig. 2 show a life testing device for a drawer slide rail according to an embodiment of the present invention, which is used for testing a drawer slide rail with a self-locking function, and testing the slide rail to be tested according to test standard requirements (for example, not less than 4 ten thousand times), closing a power supply after the test times required by the test standard are reached, judging whether the quality of the slide rail meets the requirements according to the wear degree of the slide rail, and if the slide rail is damaged after the test times are not reached, ending the test in advance.
Referring to fig. 1 and 2, in the drawer slide life testing device according to the embodiment of the invention, a slide to be tested is tested by performing a push-pull test on the drawer 100. Because the guide rail to be tested has a self-locking function, when the drawer 100 is subjected to a push-pull test, the drawer 100 needs to complete three actions of unlocking, pulling out and pushing back. The drawer slide life testing device comprises an air cylinder 10, a push-pull rod 20, a connecting piece 30 and a counting sensor 40 for measuring the use times of the slide to be tested, wherein the push-pull rod 20 is connected to the extending end of the air cylinder 10, the connecting piece 30 is arranged to be elastically telescopic, the connecting piece 30 is used for elastically connecting the push-pull rod 20 and the drawer 100, the air cylinder 10 is used for driving the push-pull rod 20 to perform one-time horizontal reciprocating motion so as to enable the drawer 100 to complete unlocking motion, and the air cylinder 10 is also used for driving the push-pull rod 20 to perform two-time horizontal reciprocating motion so as to enable the drawer 100 to complete pulling-out and pushing-back motions.
When the drawer slide life testing device is used, the drawer slide life testing device is placed on the cabinet 110 where the detection drawer 100 is located, so that occupied space can be reduced. The drawer slide life test device performs a push-pull test on the drawer 100 as follows:
Drawer 100 is unlocked: the cylinder 10 drives the push-pull rod 20 to reciprocate horizontally once to enable the drawer 100 to complete the unlocking action, and specifically comprises: firstly, the air cylinder 10 stretches out, the stretching end of the air cylinder 10 drives the push-pull rod 20 to move towards the direction away from the drawer 100, in the stretching process of the air cylinder 10, the connecting piece 30 stretches elastically along with the push-pull rod 20, and the connecting piece 30 is pulled by the push-pull rod 20, but the drawer 100 is in a self-locking state, and the connecting piece 30 stretches elastically only and cannot drive the drawer 100 to move. Then, the cylinder 10 is retracted, the extending end of the cylinder 10 drives the push-pull rod 20 to reset and apply thrust to the drawer 100, so that the drawer 100 is unlocked and rebounded, the connecting piece 30 is elastically contracted in the process of retracting the cylinder 10, and the push-pull rod 20 can directly contact the drawer 100 to apply thrust to the drawer 100 or can apply thrust to the drawer 100 through the connecting piece 30.
Drawer 100 is pulled out and pushed back: the cylinder 10 drives the push-pull rod 20 to horizontally reciprocate twice to complete the pulling-out and pushing-back actions of the drawer 100, including: firstly, the air cylinder 10 stretches out, the air cylinder 10 drives the push-pull rod 20 to move towards the direction away from the drawer 100, the connecting piece 30 stretches elastically along with the push-pull rod 20, after the connecting piece 30 stretches elastically for a certain length, the connecting piece 30 does not stretch elastically any more, and the push-pull rod 20 pulls out of the drawer 100 through the connecting piece 30. Then, the cylinder 10 is retracted, the cylinder 10 drives the push-pull rod 20 to reset, the connecting piece 30 is retracted, the push-pull rod 20 applies pushing force to the drawer 100 to enable the drawer 100 to complete pushing back, and the push-pull rod 20 can directly contact the drawer 100 to apply pushing force to the drawer 100 or can apply pushing force to the drawer 100 through the connecting piece 30.
The cylinder 10 repeats the above actions to test the service life of the drawer slide rail with the self-locking function.
It can be appreciated that the stroke of the first horizontal reciprocation of the push-pull rod 20 may be the same as the stroke of the second horizontal reciprocation, or may be different, and the stroke of the first horizontal reciprocation of the push-pull rod 20 may be set according to the actual situation, so long as the push-pull rod 20 can be reset and the pushing force applied to the drawer 100 can cause the drawer 100 to pop out. Similarly, the stroke of the second horizontal reciprocation of the push-pull rod 20 is set according to the actual situation, so long as the drawer 100 can be completely pulled out and pushed back. For simplicity of design, the stroke of the first horizontal reciprocation of the push-pull rod 20 is the same as the stroke of the second horizontal reciprocation, and is the working stroke of the cylinder 10.
The drawer slide rail life testing device provided by the embodiment of the invention has ingenious design, and the connecting piece 30 which can be elastically telescopic is arranged to connect the air cylinder 10 and the drawer 100, so that the push-pull rod 20 and the connecting piece 30 can apply acting force to the drawer 100 under the driving of the air cylinder 10 to unlock, pull out and push back the drawer 100 during testing, thereby completing the life testing of the drawer slide rail with a self-locking function. Moreover, the drawer slide rail service life testing device is high in automation degree, and service life testing can be carried out on the slide rail to be tested through the drawer slide rail service life testing device, so that dependence on manpower can be reduced, and the testing efficiency can be improved.
Referring to fig. 1, in the embodiment of the present invention, the connecting member 30 is a bungee cord.
It will be appreciated that the bungee cord may be configured in a straight line or in a polygonal shape. Drawer 100 generally includes a front side panel, a rear side panel, a left side panel, a right side panel, and a bottom panel. When the elastic cord is constructed in a straight line shape, one end of the elastic cord is fixed to the front side plate and the other end is fixed to the push-pull rod 20. When the elastic rope is constructed in a polygonal shape, a through hole can be formed in the front side plate or the bottom plate, one end of the elastic rope is wound on the push-pull rod 20, and the other end of the elastic rope is wound on the push-pull rod 20 after passing through the through hole. Moreover, the elastic cord can be wound on the drawer 100 for several turns and then wound on the push-pull rod 20, so that the elastic force provided by the elastic cord is larger, and the moving stroke of the push-pull rod 20 is also larger.
Optionally, the push-pull rod 20 is provided with a perforation 21, and the elastic rope passes through the perforation 21 and is wound on the push-pull rod 20, so that the fixation is convenient and the elastic rope cannot easily slide down.
It will be appreciated that other elastic connectors, such as tension springs, may be used for the connector 30 in addition to the bungee cords.
