Description

Technical Field

[0001] The utility model relates to the technical field of electrical cabinets, in particular to a leakage protection device for an electrical control cabinet. Background Art

[0002] As the name suggests, an electrical control cabinet is a cabinet used to install electrical automation control terminals. When the electrical control cabinet is in actual use, in order to avoid damage to internal components caused by leakage, a leakage protection device, namely a leakage protector, will be installed at the wiring point.

[0003] When the existing leakage protector is installed on the control cabinet, it is often directly fixed by bolts. However, when regular maintenance is required, the bolts need to be removed. Frequent disassembly and assembly of the bolts can easily cause damage to the bolts. At the same time, multiple bolts need to be removed, which cannot be completed with one hand and requires the use of tools, making the operation very troublesome. Therefore, we propose a leakage protection device for an electrical control cabinet. Utility Model Content

[0004] The purpose of the utility model is to provide a leakage protection device for an electrical control cabinet, which solves the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a leakage protection device for an electrical control cabinet, comprising a mounting plate, a leakage protector body is arranged on the surface of the mounting plate, clamping plates are arranged on both sides of the top of the mounting plate, strip grooves are opened on both sides of the surface of the mounting plate, a screw is rotatably installed in the inner cavity of the strip groove, an outer wall of the screw is sleeved with an adaptive threaded slider, the top of the threaded slider is fixedly connected to the clamping plate, a first bevel gear is fixedly sleeved on the outer wall of one end of the screw, a second bevel gear is meshed with the outer wall of the first bevel gear, a rotating shaft is fixed at the middle of the end face of the second bevel gear, and a turntable is fixedly connected to the top of the rotating shaft.

[0006] By adopting the above technical solution, the rotating turntable can drive the rotating shaft to rotate, thereby causing the second bevel gear to rotate, thereby driving the first bevel gear to rotate, and then causing the screw to rotate, thereby driving the threaded slider to move, thereby driving the clamping plates on both sides to move to clamp and fix the leakage protector body to ensure stability during use. At the same time, if disassembly is required, rotating the turntable in the opposite direction can drive the screw to rotate in the opposite direction, thereby causing the threaded slider to move outward, thereby causing the clamping plate to release the leakage protector body, thereby realizing disassembly.

[0007] As a preferred implementation mode of the utility model, a limiting plug block is fixed at the bottom of the leakage protector body, a limiting slot is provided at the top of the mounting plate, and the limiting plug block is inserted into the limiting slot.

[0008] By adopting the above technical solution, the limiting plug block and the limiting slot are used to initially position the leakage protector body, thereby preventing the leakage protector body from falling directly after the clamp is loosened, and at the same time, the positioning stability can be further improved during installation.

[0009] As a preferred embodiment of the utility model, the outer wall of the rotating shaft is fixedly sleeved with a bearing, both side walls of the bearing are fixed with a connecting frame, and the outer end of the connecting frame is fixedly connected to the top of the mounting plate.

[0010] By adopting the above technical solution, the arrangement of the bearing and the connecting frame makes the rotating shaft stable, thereby ensuring that the rotation of the rotating shaft can drive the second bevel gear to drive the first bevel gear.

[0011] As a preferred embodiment of the present invention, mounting holes are provided at the four corners of the top of the mounting plate.

[0012] By adopting the above technical solution and setting the mounting holes, it is convenient to connect and fix the mounting plate and the control cabinet.

[0013] As a preferred implementation mode of the utility model, a rubber pad is fixedly glued to a side wall of the clamping plate corresponding to the leakage protector body.

[0014] By adopting the above technical solution and setting the rubber pad, the clamping fit is high when clamping the leakage protector body.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The present invention provides a leakage protection device for an electrical control cabinet. After the leakage protector body is plugged in with a limiting plug block and a limiting slot, a screw is rotated to drive a threaded slider to move, thereby driving a clamping plate to clamp on both sides of the leakage protector body, thereby ensuring that the leakage protector body is firmly positioned. The detachable type can be achieved by flipping the screw with one hand, and then pulling out the leakage protector body, thereby improving the convenience of operation.

[0017] The second bevel gear can be driven to rotate by rotating the turntable, thereby causing the first bevel gear to rotate, which in turn can drive the screw to rotate, thereby further improving the convenience of operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] See also Figure 1-3 The utility model provides a technical solution: a leakage protection device for an electrical control cabinet, comprising a mounting plate 1, a leakage protector body 2 is arranged on the surface of the mounting plate 1, clamping plates 13 are arranged on both sides of the top of the mounting plate 1, strip grooves 14 are opened on both sides of the surface of the mounting plate 1, a screw 15 is rotatably installed in the inner cavity of the strip groove 14, an outer wall of the screw 15 is sleeved with an adapted threaded slider 16, the top of the threaded slider 16 is fixedly connected to the clamping plate 13, a first bevel gear 17 is fixedly sleeved on the outer wall of one end of the screw 15, a second bevel gear 18 is meshed with the outer wall of the first bevel gear 17, a rotating shaft 3 is fixed in the middle of the end face of the second bevel gear 18, and a rotating disk 31 is fixedly connected to the top of the rotating shaft 3;

[0027] In actual use, the rotating turntable 31 can drive the rotating shaft 3 to rotate, so that the second bevel gear 18 rotates, so that the first bevel gear 17 can be driven to rotate, and then the screw 15 rotates, so that the driving threaded slider 16 moves, so that the clamping plates 13 on both sides can be driven to move to clamp and fix the leakage protector body 2 to ensure stability during use. At the same time, if disassembly is required, the turntable 31 is rotated in the opposite direction to drive the screw 15 to rotate in the opposite direction, so that the threaded slider 16 moves outward, so that the clamping plate 13 releases the leakage protector body 2, thereby realizing disassembly;

[0028] Furthermore, a rubber pad 19 is fixedly glued to one side wall of the clamping plate 13 corresponding to the leakage protector body 2. The setting of the rubber pad 19 enables a high degree of clamping fit when clamping the leakage protector body 2.

[0029] Furthermore, mounting holes 12 are provided at the four corners of the top of the mounting plate 1. The arrangement of the mounting holes 12 makes it convenient to connect and fix the mounting plate 1 and the control cabinet.

[0030] It is worth mentioning that the outer wall of the rotating shaft 3 is fixedly sleeved with a bearing 32, and the two side walls of the bearing 32 are fixed with a connecting frame 33, and the outer end of the connecting frame 33 is fixedly connected to the top of the mounting plate 1. The arrangement of the bearing 32 and the connecting frame 33 makes the rotating shaft 3 stable, thereby ensuring that the rotation of the rotating shaft 3 can drive the second bevel gear 18 to drive the first bevel gear 17;

[0031] like Figure 1 and 2 As shown; a limiting plug block 21 is fixed at the bottom of the leakage protector body 2, and a limiting slot 11 is opened on the top of the mounting plate 1. The limiting plug block 21 is inserted into the limiting slot 11. The limiting plug block 21 and the limiting slot 11 are plugged together to achieve preliminary positioning of the leakage protector body 2, thereby preventing the leakage protector body 2 from falling directly after the clamping plate 13 is loosened, and at the same time, the stability of the positioning can be further improved during installation.

[0032] The implementation principle of the leakage protection device of an electrical control cabinet of the present application is: in actual use, the rotating turntable 31 can drive the rotating shaft 3 to rotate, thereby causing the second bevel gear 18 to rotate, thereby driving the first bevel gear 17 to rotate, and then causing the screw 15 to rotate, so as to drive the threaded slider 16 to move, thereby driving the clamping plates 13 on both sides to move and clamp and fix the leakage protector body 2 to ensure stability during use. At the same time, if disassembly is required, the turntable 31 is rotated in the opposite direction to drive the screw 15 to rotate in the opposite direction, thereby causing the threaded slider 16 to move outward, thereby causing the clamping plate 13 to release the leakage protector body 2, and then the leakage protector body 2 is pulled out, thereby causing the limit plug 21 to be pulled out of the limit slot 11, and disassembly can be achieved.
