Description

Technical Field

[0001] The present invention relates to the technical field of cover plates, and in particular to a clamping mechanism and an anti-mis-touch cover plate. Background Art

[0002] In modern industry, power equipment is almost the entire power source of the factory, providing energy for process equipment in various industries. Various high and low voltage electrical switchgear are needed. In the low voltage electrical switchgear, the 400V integrated measurement and control device is the core of the control system. The matching display modules such as st523 and st522 can be used for the opening and closing of switches, the display of electrical measurements, etc.

[0003] However, there are problems with this operating module. Due to size issues, the opening and closing buttons are small and close to the return button, which poses a high risk of accidental touches. At the same time, equipment inspections, meter readings, and parameter checks are frequent operations during the inspection process, further increasing the risk of accidental touches and tripping of switches. When this switch controls key equipment in the process, it may cause equipment shutdown and lead to greater accidents. For power plants, the shutdown of some key equipment may cause the entire unit to shut down, which has a huge impact. Without technical transformation, adding protective covers is a common and low-cost method, but common protective covers are usually transparent and fully covered, which cannot solve the problem of accidental touches during normal operation.

[0030] Specifically, the protection cover 100 is rotatably mounted on the anti-mistaken-touch cover plate 400 , and in an initial state, the protection cover 100 is parallel to the anti-mistaken-touch cover plate 400 .

[0031] The elastic sheet 200 is arranged on the protective cover 100, one end of the elastic sheet 200 is transmission-connected to the protective cover 100, and the elastic sheet 200 rotates synchronously with the protective cover 100; the limit block 300 is arranged at the bottom of the anti-mistaken touch cover plate 400, and a receiving space M is formed between the limit block 300 and the anti-mistaken touch cover plate 400, the other end of the elastic sheet 200 is located in the receiving space M, and the elastic sheet 200 can be snapped with the limit block 300; in the initial state, the elastic sheet 200 can not only provide a force to drive the protective cover 100 to be flush with the anti-mistaken touch cover plate, but also provide a circumferential fixing force to the protective cover 100 after the protective cover 100 is opened.

[0032] The operator can switch the state of the elastic sheet 200 pressing the limit block 300 or being engaged with the limit block 300 by rotating the protective cover 100, so that the elastic sheet 200 will not loosen when in use or not in use, thereby enhancing the stability and reliability of the structure.

[0033] Example 2

[0034] This is the second embodiment of the present invention, which is basically the same as the embodiment 1, except that.

[0035] Specifically, the end of the elastic sheet 200 located in the accommodating space M has a serrated edge to increase the friction with the limiting block 300, ensuring that the elastic sheet 200 can be more stably engaged with the limiting block 300 when the protective cover 100 is rotated.

[0036] In the design of the limit block 300 , this embodiment adds a layer of rubber pad on the surface of the pressure-bearing surface 301 to reduce the noise when the elastic sheet 200 contacts the limit block 300 and reduce the wear of both.

[0037] Through these improvements, the clamping mechanism of Example 2 improves the durability of the structure and the stability of operation while maintaining the basic functions of Example 1, and is suitable for application scenarios requiring frequent operations and high loads.

[0038] Example 3

[0039] See also Figure 2 to Figure 4 , which is the third embodiment of the present invention, and this embodiment is based on embodiment 1.

[0042] Preferably, the length of the connecting block 401 is smaller than the length of the air avoidance groove 101, the elastic sheet 200 is arranged in the area between the connecting block 401 and the inner wall of the air avoidance groove 101 in the width direction, and the elastic sheet 200 is rotatably installed on the rotating shaft 102 to improve the stability and response speed of the elastic sheet 200 when it rotates synchronously with the protective cover 100.

The connecting portion 202 is used to connect the clamping portion 201 and the elastic portion 203. The connecting portion 202 is arc-shaped, and the arc-shaped connecting portion 202 can be coaxially arranged with the rotating shaft 102. At this time, the connecting portion 202 can wrap around the rotating shaft 102, so that the elastic sheet 200 ensures stability and response speed during synchronous rotation while maintaining the compactness and strength of the structure.

[0044] Preferably, an installation groove 103 is provided on the inner wall of the air avoidance groove 101 in the length direction, the installation groove 103 is horizontally arranged, and the clamping part 201 is inserted into the installation groove 103; a pressure-bearing surface 301 is also provided on the limit block 300, and the pressure-bearing surface 301 is also horizontally arranged. In the initial state, that is, when the protective cover 100 is parallel to the anti-mistaken touch cover plate 400, the elastic part 203 can contact with the pressure-bearing surface 301 to prevent the protective cover 100 from loosening at this time; the clamping part 201 can be stably inserted into the installation groove 103, and at the same time, the elastic part 203 can contact with the pressure-bearing surface 301 to enhance the stability of the clamping.

[0046] Furthermore, a limiting tooth 303 is provided on the circumferential wall of the arc groove 302, and a plurality of limiting teeth 303 are provided, and the plurality of limiting teeth 303 are evenly arranged around the circumferential direction of the arc groove 302, thereby providing a plurality of clamping points, increasing the clamping options between the elastic sheet 200 and the limiting block 300, and preventing accidental disengagement.

[0047] Furthermore, a limiting area 304 is formed between two adjacent limiting teeth 303, and the end of the elastic part 203 can be clamped in the limiting area 304, so that the end of the elastic part 303 can be stably clamped in the limiting area 304, further improving the reliability of the clamping when the protective cover 100 is in the open state.

[0048] Example 4

In this embodiment, there are two through slots 501, one of which corresponds to the display screen on the display device, and the other corresponds to a plurality of operation buttons. In the initial state, the protective cover 100 can cover the closing button and the opening button on the display device, which effectively avoids accidental touches and improves the safety of operation.

[0052] Based on the above, the beneficial effects of the present invention are:

[0053] 1. By providing an elastic sheet, in the initial state, the elastic sheet 200 can provide a force to drive the protective cover 100 to be flush with the anti-mistaken-touch cover plate, ensuring that the protective cover 100 remains in a closed state; when in use, that is, after the protective cover 100 is opened, the elastic sheet 200 is engaged with the limiting area 304 on the limiting block 300 to provide a circumferential fixing force to the protective cover 100.

[0054] 2. By setting the arc groove 302 to be arranged concentrically with the rotating shaft 102, combined with the fact that the connecting portion 202 of the elastic sheet 200 is arc-shaped and the arc-shaped connecting portion 202 is also coaxially arranged with the rotating shaft 102, the rotation synchronization of the protective cover 100 and the elastic sheet 200 is ensured, and it is ensured that during the rotation of the protective cover 100, the clamping portion 201 of the elastic sheet 200 always moves along the contour direction of the arc groove 302 of the limit block 300, and during the movement, the clamping portion 201 of the elastic sheet 200 always clamps with the limit area 304 to avoid loosening.
