In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.
As shown in fig. 1 and 2, the device for testing the service life of a drawer slide rail according to an embodiment of the present invention is used for testing a drawer slide rail having a self-locking function, and testing the slide rail to be tested according to a test standard requirement (for example, not less than 4 ten thousand times), turning off a power supply after the test times required by the test standard are met, and then judging whether the quality of the slide rail meets the requirement according to the wear degree of the slide rail, and if the slide rail is damaged before the test times, ending the test in advance.
Referring to fig. 1 and 2, the device for testing the service life of a drawer slide according to an embodiment of the present invention tests a slide to be tested by performing a push-pull test on a 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 service life testing device for the drawer slide rail 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 rail 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 with the drawer 100, the air cylinder 10 is used for driving the push-pull rod 20 to horizontally reciprocate once to enable the drawer 100 to complete unlocking, and the air cylinder 10 is also used for driving the push-pull rod 20 to horizontally reciprocate twice to enable the drawer 100 to complete pulling-out and pushing-back actions.
When in use, the drawer slide life testing device is placed on the cabinet 110 where the detection drawer 100 is located, so that the occupied space can be reduced. The process of the drawer slide life test device for performing one-time push-pull test on the drawer 100 is as follows:
unlocking of the drawer 100: the cylinder 10 drives the push-pull rod 20 to perform a horizontal reciprocating motion once to unlock the drawer 100, which specifically includes: firstly, the air cylinder 10 extends, the extending end of the air cylinder 10 drives the push-pull rod 20 to move in a direction away from the drawer 100, the connecting member 30 elastically extends along with the push-pull rod 20 in the extending process of the air cylinder 10, and although the connecting member 30 is pulled by the push-pull rod 20, the connecting member 30 only elastically extends and cannot drive the drawer 100 to move due to the self-locking state of the drawer 100. Then, the cylinder 10 retracts, the extended end of the cylinder 10 drives the push-pull rod 20 to return and apply a pushing force to the drawer 100, so that the drawer 100 is unlocked and rebounded, the connecting member 30 elastically contracts during the retraction of the cylinder 10, and the push-pull rod 20 can directly contact the drawer 100 to apply the pushing force to the drawer 100 or apply the pushing force to the drawer 100 through the connecting member 30.
The cylinder 10 repeats the actions to test the service life of the drawer slide rail with the self-locking function.
It should be understood that the stroke of the push-pull rod 20 in the first horizontal reciprocating motion may be the same as or different from the stroke of the second horizontal reciprocating motion, and the stroke of the push-pull rod 20 in the first horizontal reciprocating motion is set according to actual conditions as long as the push force applied to the drawer 100 after the push-pull rod 20 is reset can eject the drawer 100. Similarly, the stroke of the push-pull rod 20 for the second horizontal reciprocating movement is set according to practical situations as long as the drawer 100 can be completely pulled out and pushed back. For simplicity of design, the stroke of the push-pull rod 20 in the first horizontal reciprocating motion is the same as the stroke of the second horizontal reciprocating motion, and is the working stroke of the cylinder 10.
The device for testing the service life of the drawer slide rail provided by the embodiment of the invention is ingenious in design, and the cylinder 10 and the drawer 100 are connected by arranging the connecting piece 30 capable of elastically stretching, so that the push-pull rod 20 and the connecting piece 30 can exert acting force on the drawer 100 under the driving of the cylinder 10 to realize unlocking, pulling out and pushing back of the drawer 100 during testing, and the service life test of the drawer slide rail with the self-locking function is completed. Moreover, the drawer slide rail service life testing device is high in automation degree, and the dependence on manpower can be reduced by testing the service life of the slide rail to be tested, so that the testing efficiency can be improved.
Referring to fig. 1, in the embodiment of the present invention, the connecting member 30 is an elastic cord.
It will be appreciated that the bungee cord may be configured in a straight line shape or in a polygonal shape. The drawer 100 generally includes a front panel, a rear panel, a left panel, a right panel, and a bottom panel. When the elastic cord is configured in a linear 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 formed into a polygonal shape, a through hole may be formed in the front side plate or the bottom plate, and one end of the elastic rope is wound around the push-pull rod 20 while the other end thereof is wound around the push-pull rod 20 after passing through the through hole. Furthermore, the elastic cord may be wound several times around the drawer 100 and then wound around the push-pull rod 20, so that the elastic force provided by the elastic cord is greater and the moving stroke of the push-pull rod 20 is greater.
Optionally, the push-pull rod 20 is provided with a through hole 21, and the elastic rope is wound on the push-pull rod 20 through the through hole 21, so that the fixing is convenient and the elastic rope cannot easily slip off.
It will be appreciated that the connector 30 may be provided with other resilient connectors, such as tension springs, in addition to the bungee cord.
Referring to fig. 1 and 2, in some embodiments, the push-pull rod 20 is provided with a protection pad 22, and the protection pad 22 is provided to protect the push-pull rod 20 and the drawer 100 in order to prevent the push-pull rod 20 from directly colliding with the drawer 100.
It is understood that the protection pad 22 may completely cover the push-pull rod 20, or may be disposed only at a portion of the push-pull rod 20 contacting the drawer 100.
Further, when the protection pad 22 is fixed to the push-pull rod 20, the protection pad 22 may be glued to the push-pull rod 20, or may be fixed to the push-pull rod 20 by an adhesive tape.
