The distribution cabinet body 5 is placed at the notch position on the bottom plate 1, and a first impact mechanism 6 is arranged below the top plate 3, and the first impact mechanism 6 and the second impact mechanism 7 are connected to each other. The first impact mechanism 6 comprises a mounting plate 601, a counterweight block 602, a first impact block 603, a sliding rod 604 and a second spring 605, and the counterweight block 602 is fixed symmetrically on the lower end surface of the mounting plate 601, and a first impact block 603 is arranged below the mounting plate 601, and a sliding rod 604 is fixed on the first impact block 603, and the sliding rod 604 and the mounting plate 601 are slidably connected, and a second spring 605 is fixed between the first impact block 603 and the mounting plate 601, and the mounting plate 601 is connected to the traction mechanism 8, and the second impact mechanism 7 comprises a movable plate 701, guide rod 702, connecting rod 703, vertical rod 704, adjustment plate 705, bidirectional threaded rod 706, first threaded rod 707, second impact block 708 and scale rod 709, the movable plate 701 and the guide rod 702 are connected in a sliding manner, the guide rod 702 is fixed on the top plate 3, one end of the connecting rod 703 is rotatably connected to the movable plate 701, and the other end of the connecting rod 703 is rotatably connected to the mounting plate 601, and an adjustment plate 705 is provided on the lower side of the movable plate 701. 05. The adjustment plate 705 is connected to the first threaded rod 707 through a thread. The first threaded rod 707 is connected to the second impact block 708 through a bearing. The position adjustment of the second impact block 708 is achieved through the first threaded rod 707. The gravity of the counterweight block 602 and the first impact block 603 is used to realize the detection of the upper end face of the distribution cabinet body 5. The transmission action of the connecting rod 703 is used to make the second impact block 708 move to perform impact detection on the side of the distribution cabinet body 5.

[0029] A limiting mechanism 4 is installed on the base plate 1. The limiting mechanism 4 includes a clamping plate 401, a ball 402, a cross bar 403, a fixed plate 404 and a first spring 405. The clamping plate 401 is arranged above the base plate 1, and the front end of the clamping plate 401 is a sloped structure. Balls 402 are installed on the clamping plate 401 at equal intervals. At the same time, the balls 402 contact the distribution cabinet body 5 and can roll; a cross bar 403 is fixed to the clamping plate 401, and the cross bar 403 and the fixed plate 404 are slidably connected, and the fixed plate 404 is fixed to the base plate 1; one end of the first spring 405 is fixed to the clamping plate 401, and the other end of the first spring 405 is fixed to the fixed plate 404;

[0030] When using the strength detection device for power distribution cabinet processing, if Figure 1-Figure 7As shown, first, the distribution cabinet body 5 is pushed into the groove on the bottom plate 1 by the universal wheel at the lower end of the distribution cabinet body 5. When the distribution cabinet body 5 contacts and slides with the inclined surface of the front end of the splint 401, the splint 401 is forced to move. The rolling effect of the ball 402 can reduce the friction between the distribution cabinet body 5 and the splint 401, making it easier for the distribution cabinet body 5 to move. The sliding guide effect between the cross bar 403 and the fixed plate 404 can ensure the stability of the movement of the splint 401. At this time, the first spring 405 is forced to contract until the distribution cabinet body 5 moves to just below the first impact block 603. At this time, the first spring 405 provides a force to achieve the limiting effect of the distribution cabinet body 5.

[0031] Vertical rods 704 are fixed symmetrically on the front and back of the movable plate 701, and the vertical rods 704 are slidably connected to the adjustment plate 705. The adjustment plate 705 and the movable plate 701 are connected to the bidirectional threaded rod 706 through threads. A scale rod 709 is fixed to the second impact block 708, and the scale rod 709 is slidably connected to the adjustment plate 705.

[0032] After the power distribution cabinet 5 is installed, Figure 1-Figure 7 As shown, at this time, the first impact block 603 is located at the uppermost side, and the arc-surface protrusion 801 is snap-fitted to the card plate 802. Then, the position of the second impact block 708 is adjusted according to the width of the distribution cabinet body 5. By rotating the bidirectional threaded rod 706 and coordinating the threaded connection between the bidirectional threaded rod 706, the adjustment plate 705 and the movable plate 701, the distance between the adjustment plate 705 and the movable plate 701 can be adjusted, thereby adjusting the height of the second impact block 708. Then, by the threaded connection between the first threaded rod 707 and the adjustment plate 705, the left and right position of the second impact block 708 can be adjusted. By coordinating the sliding action between the scale rod 709 and the adjustment plate 705, the stable movement of the second impact block 708 can be ensured. Then, by coordinating the scale on the scale rod 709, the position of the second impact block 708 can be determined, ensuring that the second impact block 708 can contact the distribution cabinet body 5 to achieve the impact during the later detection process.

[0033] The traction mechanism 8 includes a cambered block 801, a clamping plate 802, a mounting block 803, an inclined block 804 and a hydraulic rod 805. The cambered block 801 is fixed to the upper end surface of the mounting plate 601, and the cambered block 801 and the clamping plate 802 are in a snap-fit connection; the clamping plate 802 and the mounting block 803 are in a rotational connection, and a torsion spring is further connected between the clamping plate 802 and the mounting block 803; the clamping plate 802 and the inclined block 804 are in a sliding connection, and the inclined block 804 is fixed to the top plate 3, and the inclined block 804 and the clamping plate 802 are distributed in a one-to-one correspondence; the mounting block 803 is fixed to the output end of the hydraulic rod 805, and the hydraulic rod 805 is fixed to the top plate 3;

[0034] After the device adjustment is completed, Figure 1-Figure 7 As shown, during the inspection, by controlling the hydraulic rod 805 to contract, the arc-surface convex block 801, the card plate 802 and the mounting plate 601 are driven to move upward. At this time, the card plate 802 contacts and slides with the inclined block 804. The sliding action between the card plate 802 and the inclined block 804 causes the card plate 802 to rotate under force. When the card plate 802 is separated from the arc-surface convex block 801, the locking effect on the mounting plate 601 is released. At this time, under the action of the gravity of the counterweight block 602 and the first impact block 603, the first impact block 603 falls downward. When the first impact block 603 is in contact with the distribution cabinet When the main body 5 collides, the detection function of the upper end surface of the distribution cabinet main body 5 can be realized, and when the mounting plate 601 moves downward, the transmission function of the connecting rod 703 is cooperated to make the guide rod 702, the adjustment plate 705 and the second impact block 708 move. When the first impact block 603 contacts the distribution cabinet main body 5, the second impact block 708 does not contact the distribution cabinet main body 5 at this time. Under the action of the gravitational potential energy of the counterweight block 602, when the first impact block 603 contacts and collides with the distribution cabinet main body 5, the mounting plate 601 can continue to move downward a certain distance relative to the counterweight block 602. , with the transmission effect of the connecting rod 703, the second impact block 708 can contact and collide with the distribution cabinet body 5 to produce an impact effect, thereby realizing the detection effect of the side of the distribution cabinet body 5. According to the above principle, the multi-faceted detection effect of the distribution cabinet body 5 can be realized simultaneously. The degree of deformation of the distribution cabinet body 5 after the impact can be used to determine whether the quality of the distribution cabinet body 5 is qualified. After the detection is completed, the hydraulic rod 805 is extended to drive the mounting block 803 and the card plate 802 to move downward. When the card plate 802 is separated from the inclined block 804, the card plate is caused to move downward under the action of the torsion spring. 802 returns to a vertical state. When the card plate 802 moves down to contact the arc-surface protrusion 801 on the mounting plate 601, the card plate 802 can be flipped over by the sliding action between the card plate 802 and the arc-surface protrusion 801 until the card plate 802 is engaged with the arc-surface protrusion 801 through the action of the torsion spring. Finally, the first impact mechanism 6 and the second impact mechanism 7 can be driven to reset by the contraction of the hydraulic rod 805 until the upper end of the card plate 802 is in contact with the inclined block 804 so that the next test can be carried out. This is the working principle of the strength detection device for distribution cabinet processing.

[0035] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
