Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The present invention is a locking mechanism for a domain controller circuit board test box. The locking mechanism includes a support plate 1 symmetrically arranged on the base of the test box, and a card symmetrically arranged on the body of the test box. The locking pin 2, the clamping plate 3 that moves longitudinally on the inner side of the support plate 1 for engaging the locking pin 2 on the support plate 1 and is arranged on the support plate 1 for driving the A driving mechanism for the movement of the clamping plate 3 , the end of the clamping plate 3 away from the base is provided with a guide slot 10 for locking the locking pin 2 .

When in use, place the circuit board PCBA in the test box, then align the locking pin 2 on the box with the guide slot 10, and push the box close to the base of the test box, and then drive the card 3 to slide through the driving mechanism , so that the locking pin 2 enters the inside of the guide slot 10, and locks the test box shell and the test box base.

Compared with direct docking, the pre-docking is carried out through the guide slot 10 and the locking pin 2. During the pre-docking, the pin needle is in an unbonded state, and then the driving mechanism drives the clamping plate 3 to move, driving the box body and the test box base. The interface docking can effectively avoid the problem of pin damage caused by direct docking; at the same time, the locking plate is driven by the driving mechanism without cylinder pulling, and the operation is convenient, which can effectively avoid equipment wear and facilitate maintenance.

Specifically, an arc-shaped hole 7 is opened on the support plate 1 , and a long waist hole A8 is opened on the clamping plate 3 at a position corresponding to the arc-shaped hole 7 . The drive mechanism includes a rotating shaft 4 rotatably mounted on the support plate 1, a handle 5 and a connector 6 fixedly arranged on both ends of the rotating shaft 4 corresponding to the outside of the support plate 1, and passing through the The two fixed pins 9 of the arc hole 7 and the long waist hole A8 are respectively connected with the handle 5 and the connector 6 .

When docking and locking, by turning the handle 5, the rotating shaft 4, the connector 6 and the fixed pin 9 are driven to rotate. At this time, the fixed pin 9 rotates along the arc-shaped hole 7, and with the cooperation of the long waist hole A8, the clamping plate is driven 3 moves downwards, so that the guide groove 10 on the card plate 3 is locked on the locking pin 2, thereby locking the test box body and the test box base.

It should be noted that, when the clamping plate 3 is in the open state, the long waist hole A8 is located at the higher end of the arc hole 7, while in the locked state, the long waist hole A8 is located at the lowest end of the arc hole 7. When locking, the fixed pin 9 moves from the higher end of the arc hole 7 to the lower end, and cooperates with the long waist hole A8 to push the clamping plate 3 to move downward, so that the clamping plate 3 is engaged in the locking position. on the pin 2; on the contrary, when it is opened, the handle drives the fixed pin 9 to move from the lowest end of the arc hole 7 to the highest end, so that the clamping plate 3 releases the locking pin 2.

Further, in order to avoid the deviation of the cardboard 3 under the rotation trend of the handle 5 and the rotating shaft 4, and ensure the stability of the cardboard 3 structure; the position corresponding to the cardboard 3 on the support plate 1 is provided with a The positioning bolts 11 of the clamping plate 3; the position of the clamping plate 3 corresponding to the positioning bolts 11 is provided with a long waist hole B. It should be noted that there are at least two positioning bolts 11 .

In addition, the present invention also provides a test box, which includes the above-mentioned locking mechanism for a domain controller circuit board test box.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. within range.
