[0027] 2051. Incline. Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0029] Example 1: An electronic protection and unmanned monitoring device for hazardous work areas, see [link to example]. Figures 1 to 5 It includes an alarm control box 1 and a protective structure 2; the protective structure 2 is arranged on the outgoing side of the alarm control box 1.

[0030] The protective structure 2 includes a protective cover A201 and a protective cover B202; the protective cover A201 is fixedly installed at the rear end of the outgoing line side of the alarm control box 1; the protective cover B202 is movably installed at the front end of the outgoing line side of the alarm control box 1; wherein, one end of the protective cover B202 is rotatably connected to one end of the protective cover A201 via a hinge 203; wherein, the top of the protective cover A201 and the protective cover B202 are respectively provided with several corresponding circular grooves 2010 on opposite sides, and the protective cover A201 and the protective cover B202 are closed to cover the wire harness on the outgoing line side of the alarm control box 1.

[0031] This utility model, by setting up protective covers A201, protective covers B202 and hinges 203, has the advantage of closing and covering the wire harness connector with protective covers A201 and protective covers B202 after the wire harness passes through, thus protecting the wire harness connector. This solves the problem that the wire harness connector connected from the control box connector is easily damaged in the coal mine environment.

[0032] Specifically, rubber pads 2011 are arranged on the inner walls of the circular grooves 2010 on protective covers A201 and B202, respectively. The rubber pads 2011 compress the wire harness and clamp the wire harness more tightly.

[0033] Furthermore, connecting blocks 204 are fixedly installed at the other ends of protective covers A201 and B202, respectively. A fixing block 206 is fixedly installed on the back of one connecting block 204. A vertical section of a U-shaped locking block 205 is inserted through a hole on the fixing block 206. The U-shaped locking block 205 engages with the top of the two connecting blocks 204. A push block 207 is fixedly installed at the top of one vertical section of the U-shaped locking block 205. Two springs 208 are symmetrically arranged between the push block 207 and the fixing block 206. The two ends of the springs 208 are fixedly connected to the push block 207 and the fixing block 206, respectively. The elastic coefficient of the springs 208 can be selected and used by the technical personnel of this profession according to the actual situation.

[0034] This utility model, by setting up a connecting block 204, a fixing block 206, a U-shaped locking block 205, a pushing block 207, and a spring 208, has the advantage that after the protective cover A201 and the protective cover B202 are closed, the two connecting blocks 204 are locked by the U-shaped locking block 205 for positioning, so that the protective cover A201 and the protective cover B202 are stably connected.

[0035] Furthermore, the inner side of the other vertical end of the U-shaped block 205 is set as a slope 2051. When the U-shaped block 205 locks the two connecting blocks 204, the slope 2051 allows one connecting block 204 to be pushed to fit tightly against the other connecting block 204 when the two connecting blocks 204 are not very close together.

[0036] It is worth noting that a limiting block 209 is fixedly provided on the outer side of one vertical end of the U-shaped card block 205. The limiting block 209 cooperates with the bottom side of the fixed block 206 to limit the upward movement distance of the U-shaped card block 205.

[0037] Working principle: Using the device of this utility model, after the wire harness is installed, push the push block 207 to move the U-shaped locking block 205 upward, rotate the protective cover B202 to contact the protective cover A201, and after the two connecting blocks 204 contact, release the push block 207. Under the action of the stretched spring 208, the push block 207 drives the U-shaped locking block 205 downward. The U-shaped locking block 205 locks the two connecting blocks 204 for positioning, protecting the wire harness connector connected from the control box connector.

[0038] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
