[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, Figure 1 What is shown is a front view schematic diagram of a fixing bracket in an embodiment; Figure 2 What is shown is a cross-sectional schematic diagram (side view) of the fixing bracket in the embodiment; Figure 3 It shows Figure 2 Schematic diagram of installing a magnetic switch;

[0025] The device includes:

[0026] Main frame 10;

[0027] The mounting structure includes a base plate 21 arranged on one side of the main frame 10, and movable clamping plates 23 are symmetrically arranged on the upper and lower ends of the base plate 21 away from the main frame 10. A slot for accommodating the switch body is formed between the symmetrical clamping plates 23. After the switch body is inserted into the slot, the symmetrical clamping plates 23 clamp the switch body and protect it in the vertical direction.

[0028] Specifically, the main frame 10 is vertically arranged at the bottom of the well, and the vertically installed switch body can reduce the risk of itself being hit; the movable clamping plate 23 not only plays the role of installing and clamping the switch body, but also because the clamping plate 23 is arranged up and down, it can also play a certain protective role for the switch body, preventing vertically falling ore and the like from directly hitting the switch body.

[0029] The provided installation structure plays a role in quickly installing and disassembling the switch body. When disassembling the switch body, the switch body can be pulled out from between the clamping plates 23, which is convenient and fast, and is convenient for daily maintenance and disassembly and replacement of the switch body.

[0030] like Figure 1 , Figure 2 , Figure 3 As shown, Figure 1 What is shown is a front view schematic diagram of a fixing bracket in an embodiment; Figure 2 What is shown is a cross-sectional schematic diagram (side view) of the fixing bracket in the embodiment; Figure 3 It is shown that Figure 2 Schematic diagram of installing a magnetic switch;

[0031] The base plate 21 includes a fixing portion disposed at one end away from the main frame 10 .

[0032] The mounting structure also includes a fixing plate 24 and a fixing column 25. The fixing plate 24 is arranged on the end surface of the substrate 21 on which the clamping plate 23 is arranged, and is arranged at one end where the two clamping plates 23 are away from each other. One end of the fixing column 25 is connected to the fixing plate 24, and the other end passes through the clamping plate 23 and is connected to the fixing portion of the substrate 21 located below it. The clamping plate 23 can slide up and down along the fixing column 25, and a spring 26 is also sleeved on the outside of one end of the fixing column 25 located between the clamping plate 23 and the fixing plate 24.

[0033] The movable installation of the clamping plate 23 is realized by the set fixing plate 24, fixing column 25 and spring 26. When the switch body is inserted between the two clamping plates 23, the two clamping plates 23 are moved away from each other and the springs 26 on the corresponding sides are respectively compressed. After the switch body is inserted, the two clamping plates 23 clamp the upper and lower ends of the switch body under the action of the spring 26.

[0034] An inclined surface is provided at one end of the two clamping plates 23 that are close to each other; the inclined surface facilitates the switch body to be inserted into the slot formed between the two clamping plates 23 .

[0035] The end face of the base plate 21 away from the main frame 10 is also provided with an insertion rod 22 parallel to the clamping plate 23. The switch body includes a switch base 1. The end face of the switch base 1 close to the insertion rod 22 is correspondingly provided with a socket. The insertion rod 22 is matched and plugged into the socket of the switch base 1.

[0036] By providing an insertion rod 22 that matches the insertion hole of the switch base 1, the installation of the switch body is positioned and the installation stability is further guaranteed.

[0037] The main frame 10 is U-shaped, and the mounting structure is arranged in one open end of the main frame 10 . A protective plate 11 is also arranged at the top of the main frame 10 .

[0038] The protection plate 11 disposed on the top of the main frame 10 protects the mounting structure and the switch body disposed thereunder, thereby preventing falling ores and the like from directly hitting the mounting structure and the switch body.

[0039] The contact end surfaces of the base plate 21 and the main frame 10 are both provided with mounting holes, and bolts 211 are arranged in the mounting holes to connect the two. The provided mounting holes and the matching bolts 211 realize the installation and fixation of the base plate 21.

[0040] Working principle: When installing the switch body through this device, firstly, the mounting structure is locked and fixed to one side of the main frame 10 vertically arranged at the bottom of the well by bolts 211, and then the switch body is inserted into the slot formed between the two clamping plates 23, and at the same time, the plug rod 22 is inserted into the plug hole of the switch base 1. After the switch body is inserted, under the action of the spring 26, the two clamping plates 23 clamp the upper and lower ends of the switch body, and combined with the cooperation of the plug rod 22 and the plug hole, the switch body is stably installed;

[0041] When disassembling the switch body, just pull the switch body out from between the clamping plates 23.

[0042] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
