DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments. The technical solutions in the embodiments of the utility model are clearly and completely described, and the described embodiments are only embodiments of a part of the invention, not all of it. Based on the embodiments in the invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the invention.

[0024] like Figures 1 to 7 As shown, the utility model patent designs an embodiment of a battery compartment based on a mine pressure monitoring device. In this embodiment, the battery compartment includes a cylindrical cavity 1 arranged on the mine pressure monitoring device 4. The cylindrical cavity 1 is stamped from a stainless steel plate and fixed inside the mine pressure monitoring device 4. The top of the cylindrical cavity 1 is open on the shell surface of the mine pressure monitoring device 4, and a compartment cover assembly port 2 is welded at the opening. A battery compartment cover 3 is snap-assembled at the compartment cover assembly port 2. Battery contacts are arranged on the bottom side of the cylindrical cavity 1. The battery contacts include two spring-type contacts, positive and negative poles, which are electrically connected to the functional components of the mine pressure monitoring device 4.

[0025] The assembly port 2 of the bin cover is also made by stamping of stainless steel material and welded at the top opening of the cylindrical cavity 1, including a stainless steel sleeve 21, which is sleeved on the outside of the cylindrical cavity 1, and an annular mounting groove 22 is welded on the top outer edge of the sleeve 21. The cross section of the mounting groove 22 is C-shaped and the opening is set downward. Two bayonet holes 222 are symmetrically opened at both ends of the outer edge plate 221 of the mounting groove 22. The outer edge plate 221 is divided into two sections by the bayonet holes 222 at both ends, and the height of the two sections is centrally symmetrical on both sides of the bayonet hole 222. The outer edge plate 221 of the mounting groove 22 of the bin cover assembly port 2 is axially protruded with an anti-slip block 223 at the lowest height on one side of the bayonet hole 222. The height of the anti-slip block 223 is lower than the highest height of the outer edge plate 221, and a positioning groove 224 is axially concave at the highest height near the other side of the bayonet hole 222.

[0026] The battery compartment cover 3 is disc-shaped and is formed by stamping a stainless steel plate. Hook plates 33 are symmetrically bent radially inward at both ends of the lower side of the edge. The positions of the hook plates 33 at both ends correspond to the positions of the two snap-in slots 222 on the outer edge plate 221 of the mounting groove 22 of the compartment cover assembly port 2. The width of the snap-in slot 222 is greater than that of the hook plate 33, and the width of the positioning groove 224 is the same as that of the hook plate 33.

[0027] A tightening plate 32 is connected to the inner side of the battery compartment cover 3, and the center of the tightening plate 32 is slidably connected to the center of the cover body of the battery compartment cover 3 through a short column 321. One end of the short column 321 is fixedly connected to the tightening plate 32, and the other end passes through the opening at the center of the cover body of the battery compartment cover 3 and is connected to a baffle 322. A tightening spring 323 is sleeved on the short column 321, and the two ends of the tightening spring 323 respectively press against the tightening plate 32 and the cover body of the battery compartment cover 3. A sealing silicone layer 34 is applied to the inner side of the cover body of the battery compartment cover 3, and a sealing rubber ring 324 is provided between the inner side of the baffle 322 and the outer surface of the cover body of the battery compartment cover 3.

[0028] When the battery compartment based on the mine pressure monitoring equipment disclosed in the utility model patent is used, a rechargeable battery 5 is used, and the output contact of the battery is located at one end, corresponding to the position of the battery contact at the bottom of the battery compartment. After the rechargeable battery 5 is placed, the two hook plates 33 at the bottom of the battery compartment cover 3 are respectively aligned with the positions of the two bayonet holes 222 of the compartment cover assembly port 3, and the battery compartment cover 3 is pressed down with force to make the hook plate 33 pass over the anti-detachment block 223, and then the battery compartment cover 33 is screwed from the lower end of the outer edge plate 221 of the compartment cover assembly port 3 to the higher end, and when the two hook plates 33 are respectively inserted into the corresponding positioning grooves 224, the screwing is stopped, and the assembly of the battery compartment cover 3 is completed at this time. The top plate 32 presses down the rechargeable battery in the compartment under the action of the top spring 323, so that it fits tightly with the battery contact at the bottom of the compartment, and the baffle 322 on the outside of the compartment cover presses the sealing rubber ring 324 to form a seal.
