[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] See also Figure 1 As shown, the utility model is a mining telephone, comprising a cabinet 1 and a cabinet door 10 hinged on one side of an opening end of the cabinet 1, and a telephone body 100 is installed on the inner back surface of the cabinet 1, a limiting structure A is fixed on an inner side wall of the cabinet 1, and a limiting structure B cooperating with the limiting structure A is installed on the inner wall surface of the cabinet door 10.

[0028] Specifically, Figure 2-3 The limiting structure A includes a telescopic cylinder 13 connected to the controller, a movable plate 131 is fixed at the end of the telescopic cylinder 13, three touch rods 132 are connected to one side of the movable plate 131, and a guide block 14 is installed on the inner wall of the cabinet 1 at the end of the touch rod 132. The guide block 14 is provided with a guide hole 142 for inserting the touch rod 132 at one end close to the telescopic cylinder 13, and a through hole 143 is provided on the bottom side of the guide hole 142. At the same time, a slider 144 that slides along the inner wall of the guide hole 142 is connected to the bottom side of the guide hole 142 through a spring B145; a limiting rod 141 that passes through the through hole 143 is connected to one side of the slider 144. The limiting structure B includes a rectangular block 11, and three limiting holes for inserting the limiting rod 141 are provided on one side of the rectangular block 11.

[0029] The contact rod 132 , the guide block 14 , the sliding block 144 and the limiting plug rod 141 integrally constitute a limiting pin.

[0030] Based on the actual structural setting of the above-mentioned limit structure A and limit structure B, when in use, when the cabinet door 10 is opened to the maximum angle, that is, when the cabinet door 10 is in a vertical state with the cabinet body 1, the limit rod 141 is inserted into the limit hole; that is, when the cabinet door 10 needs to be closed at this time, it is necessary to control the limit rod 141 to slide out of the limit hole in advance.

[0031] Based on this, the present application is provided with a detection mechanism connected to the controller, which is installed at the bottom of the open end of the cabinet 1. The detection mechanism is used to detect whether there is a power cord 1001 on the bottom of the open side of the cabinet 1. One end of the power cord 1001 is connected to the telephone body 100 and the other end is connected to the microphone.

[0032] Specifically, the detection mechanism includes a side plate 12, such as Figure 4-6 Three mounting grooves are provided at the bottom of the open end of the cabinet 1, and elastic telescopic structures are installed in the three mounting grooves and are arranged obliquely from the inside to the outside. The elastic telescopic structure includes a connecting sleeve 124 installed on the bottom side of the mounting groove, and the bottom side of the connecting sleeve 124 is connected to a connecting column 123 through a spring A125, and the end of the connecting column 123 is welded or bolted to the inner side of the side plate 12; at the same time, in order to facilitate detection, the end of a connecting column 123 in the three elastic telescopic structures is connected to a push rod 126, and a pressure sensor 128 cooperating with the push rod 126 is provided on the bottom side of the connecting sleeve 124, and the pressure sensor 128 is connected to the controller.

[0033] When the power cord 1001 is placed on the side panel 12, the side panel 12 is controlled to move toward the side close to the cabinet 1 under the action of the power cord 1001. When the push rod 126 hits the pressure sensor 128, the pressure sensor 128 detects a signal, and the controller controls the telescopic cylinder 13 to extend; when the signal detected by the pressure sensor 128 disappears, the controller controls the telescopic cylinder 13 to retract.

[0034] It is known that if Figure 5 A plurality of convex plates 121 having the same length direction as the side plate 12 are arranged on the inner side of the side plate 12, and reinforcing ribs 122 are arranged on both sides of the convex plates 121. The structural strength of the side plate 12 is improved by the arrangement of the convex plates 121 and the reinforcing ribs 122.

[0035] The connection column 123 of the present application is arranged along the connection sleeve 124 from the inside to the outside and upwardly inclined; and a foam layer 127 is arranged at the end of the top rod 126.
