At this time, the hinge seat 55 is restricted on the rotating support plate 54 and the limiting protrusion, thereby realizing the installation of the hinge seat 55.

[0033] In order to realize the opening and closing test of the test cover 6, a support base 15 is further fixed inside the sealed test box 3, wherein a symmetrical support plate 14 is fixedly mounted on the support base 15, and a lifting mechanism 13 for longitudinally supporting the test cover 6 is provided on the symmetrical support plate 14.

This makes it easy to simulate different test conditions according to different environments to ensure sufficient testing of the test cover 6, so as to facilitate judgment on whether the test cover 6 is prone to deformation under various circumstances, so as to meet the test integrity of the test cover 6.

[0034] Furthermore, the lifting mechanism 13 includes a symmetrical supporting telescopic rod 131, wherein the symmetrical supporting telescopic rod 131 is respectively fixedly mounted on the symmetrical supporting plate 14, and a supporting top plate 132 is fixedly mounted at the output end of the symmetrical supporting telescopic rod 131, wherein the supporting top plate 132 is provided with a contact assembly for supporting the test cover plate 6, that is, when in use, the action of the symmetrical supporting telescopic rod 131 is utilized to realize the longitudinal lifting of the supporting top plate 132, thereby facilitating the control of the height of the contact assembly, and utilizing the contact assembly to contact the bottom of the test cover plate 6 to realize the bottom support of the test cover plate 6.

[0035] In the present application, the contact assembly includes a limiting vertical plate 134, wherein the limiting vertical plate 134 is fixedly mounted on the supporting top plate 132, wherein a top limiting bracket 133 is fixedly mounted on the limiting vertical plate 134, a limiting slide groove 136 is provided on the top limiting bracket 133, and a limiting slide plate 1310 is slidingly arranged inside the limiting slide groove 136, wherein an arc-shaped lifting block 135 for contacting the bottom of the test cover plate 6 is fixedly mounted on the limiting slide plate 1310, and a hinged rod 137 is rotatably arranged at the bottom of the limiting slide plate 1310, wherein the hinged rod 137 is rotatably mounted on the adjustment support frame 139, and the adjustment support frame 139 is fixedly mounted on the adjustment telescopic rod 138, and the adjustment telescopic rod 138 is fixedly mounted on the supporting top plate 132. During use, the height of the support frame 139 is adjusted by adjusting the start control of the telescopic rod 138, thereby controlling the angle of the hinged rod 137, so that the limiting slide 1310 slides inside the limiting slide groove 136, thereby adjusting the distance between the two sets of adjacent arc-shaped lifting blocks 135, so that the arc-shaped lifting blocks 135 can contact and lift test cover plates 6 of different shapes and sizes, and the shape and distance of the arc-shaped lifting blocks 135 are adjustable, which can avoid the beautiful lines on the test cover plate 6 and avoid the squeezing of the beautiful lines caused by high pressure, thereby causing inaccurate test results.

[0036] Furthermore, the pressure mechanism 12 includes a top push rod 121, wherein the top push rod 121 is fixedly mounted on a top support frame 127, and the top support frame 127 is fixedly mounted on the side vertical rod 16, and the output end of the top push rod 121 is fixedly mounted with a pressure support frame 122, and a pressure adjustment cylinder 126 is symmetrically fixedly mounted on the pressure support frame 122, wherein the output end of the pressure adjustment cylinder 126 is fixedly mounted with a pressure adjustment support plate 123, and the pressure adjustment support plate 123 and the pressure adjustment cylinder 126 are slidingly connected, and at the same time, a detachable bracket 125 is fixedly mounted on the pressure adjustment support plate 123, and an arc-shaped pressure plate 124 is mounted on the detachable bracket 125 by bolts, that is, the arc-shaped pressure plate 124 is arc-shaped, and the arc-shaped pressure plate 124 is replaceable relative to the detachable bracket 125. In the present application, the longitudinal movement of the pressure support frame 122 is controlled by the action of the top push rod 121, thereby controlling the height of the pressure adjustment cylinder 126, and then the pressure adjustment cylinder 126 is used to control the distance between the pressure adjustment support plates 123, and at the same time control the position of the arc pressure plate 124, so that the arc pressure plate 124 can act on the test cover 6, and the shape of the arc pressure plate 124 in the present application can adapt to the shape of the test cover 6 to achieve sufficient pressure on the test cover 6, and at the same time, the shape and size of the arc pressure plate 124 can be replaced according to the shape of the test cover 6, and the above functions are achieved under the detachable connection between the arc pressure plate 124 and the detachable bracket 125.

[0037] When the present invention is in use, the test cover plate 6 is first clamped by the mounting mechanism 5, that is, the switch cabinet door 4 is first opened, and then the test cover plate 6 is placed into the interior of the sealed test box 3. At this time, the rotating support plate 54 is placed on the side support base 51, and then, under the action of the ball 56, the rotating support plate 54 slides on the side support base 51. When it slides to the limit protrusion position on the side support base 51, the damping shaft 53 is rotated by the power motor, so that the rotating support plate 54 rotates 90 degrees. The hinge seat 55 is tightly pressed on the hinge seat 55. At this time, the hinge seat 55 is restricted on the rotating support plate 54 and the limiting protrusion, thereby realizing the installation of the hinge seat 55. At the same time, the bottom surface of the test cover 6 contacts the arc-shaped lifting block 135. The height of the support frame 139 is adjusted by adjusting the start control of the telescopic rod 138, thereby controlling the angle of the hinge rod 137, so that the limiting slide 1310 slides inside the limiting slide groove 136, thereby adjusting the distance between the two sets of adjacent arc-shaped lifting blocks 135, so that the arc-shaped lifting blocks 135 can contact test cover plates 6 of different shapes and sizes. At the same time, by judging whether it is necessary to apply pressure to the test cover 6, if necessary, the top push rod 121 is used to control the longitudinal movement of the pressure support frame 122, thereby controlling the height of the pressure adjustment cylinder 126, and then using the pressure adjustment cylinder 126 to control the distance between the pressure adjustment support plates 123, and at the same time control the position of the arc pressure plate 124, so that the arc pressure plate 124 can act on the test cover 6, and the shape of the arc pressure plate 124 in this application can adapt to the shape of the test cover 6, so as to achieve full pressure on the test cover 6. Pressure, at this time, the pressure applied to the test cover 6 is sensed by the pressure sensor, so as to realize the pressurizing function of the test cover 6, and then the symmetrical support telescopic rod 131 is started to control the arc-shaped lifting block 135 to squeeze the test cover 6 upward. At this time, the pressure obtained by the pressure sensor is judged until the pressure sensor detects that the pressure reaches the critical point, and the downward pressing function of the arc-shaped pressure plate 124 is released. At this time, the deformation of the test cover 6 is detected to judge the opening and closing status of the test cover 6 under the applied pressure state, so as to obtain a more accurate test state of the test cover 6.
