[0025] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0026] like Figure 1-7 As shown, the utility model is a battery-type digital differential pressure gauge, comprising: a gauge body 1, a battery cover 2, a battery slot opened on one side of the gauge body 1, a battery 4 installed in the inner cavity of the battery slot, and a plug-in mechanism for facilitating installation and removal of the battery cover 2, wherein the plug-in mechanism is provided with two groups, which are symmetrically arranged on both sides of the battery cover 2; the battery cover 2 is located in the inner cavity of the battery slot, and the outer edge of the battery cover 2 and the inner wall of the battery slot are arranged to fit each other, and when the battery 4 is replaced, the battery cover 2 can be easily disassembled through the plug-in mechanism, at which time the battery 4 can be taken out, and when replaced with a new battery 4, the battery cover 2 can be easily installed again through the plug-in mechanism, thereby realizing rapid replacement of the battery 4.

[0027] The plug-in mechanism comprises: a mounting groove 1 and a mounting groove 2 provided on the side wall of the battery cover plate 2, the inner cavities of the mounting groove 1 and the mounting groove 2 being mutually interpenetrating, a plug-in groove provided on the inner wall of the battery groove, a plug-in board 7 movably installed in the inner cavity of the mounting groove 1 and plugged into the inner cavity of the plug-in groove, a linkage spring 9 fixedly installed between the plug-in board 7 and the inner wall of the mounting groove 1, one end of the linkage spring 9 fixedly installed on one side of the plug-in board 7, and the other end fixedly installed on the inner wall of the mounting groove 1, a connection board 8 fixedly installed on one side of the plug-in board 7 and sliding in the inner cavity of the mounting groove 2;

[0028] When the battery 4 needs to be replaced, the two connecting plates 8 are pressed at the same time to make the two connecting plates 8 approach each other, and the two connecting plates 8 drive the adjacent plug-in plates 7 to approach each other, and drive the adjacent linkage springs 9 to be compressed, so that the two plug-in plates 7 are separated from the adjacent plug-in slots, and the battery cover 2 can be easily disassembled at this time. When the battery 4 is replaced, the battery cover 2 is reset to the inner cavity of the battery slot, and the two connecting plates 8 are loosened. The elastic force of the two linkage springs 9 can drive the adjacent plug-in plates 7 to move away from each other, so that the two plug-in plates 7 are respectively plugged into the inner cavities of the adjacent plug-in slots, so that the battery cover 2 can be easily installed;

[0029] The plug-in mechanism of the present application can facilitate the installation and removal of the battery cover 2, thereby realizing the rapid replacement of the battery 4, and solving the problem that the existing battery cover 2 is fixed to the watch body 1 by bolts, and when the battery 4 needs to be replaced, it is troublesome to disassemble it, and it cannot be disassembled without tools, which wastes time and causes inconvenience in replacing the battery 4.

[0030] A limit block 6 is fixedly installed on one side of the battery cover 2, and a groove matching the battery 4 is opened on one side of the limit block 6; when the battery cover 2 is installed, the two grooves on the limit block 6 correspond to the two batteries 4 respectively, so that the two batteries 4 are respectively engaged in the adjacent groove cavities, thereby limiting the battery 4, avoiding the problem of poor circuit contact caused by the battery 4 shaking in the battery slot cavity when the watch body 1 is hit, thereby ensuring the normal use of the watch body 1.

[0031] A sealing groove is opened on one side of the watch body 1 along the circumference of the battery cover 2, and the inner cavity of the sealing groove and the inner cavity of the battery slot are interconnected, a sealing plate 3 is fixedly installed on the side wall of the battery cover 2, and a sealing gasket 5 is fixedly installed on one side of the sealing plate 3; when the battery cover 2 is installed, the sealing plate 3 and the sealing gasket 5 are both located in the inner cavity of the sealing groove, and the outer sides of the sealing plate 3 and the sealing gasket 5 are both arranged to fit each other with the inner wall of the sealing groove, thereby improving the sealing effect of the battery cover 2, effectively reducing the dust and moisture entering the inner cavity of the battery slot and affecting the use of the battery, thereby achieving the protection effect of the battery, and further ensuring the normal use of the watch body 1.

[0032] Working principle: when in use, that is, when the battery 4 needs to be replaced, the two connecting plates 8 are pressed at the same time, so that the two connecting plates 8 are close to each other, and the adjacent plug-in plates 7 are driven to be close to each other by the two connecting plates 8, and the adjacent linkage springs 9 are driven to be compressed, so that the two plug-in plates 7 are separated from the adjacent plug-in slots, and the battery cover 2 can be easily disassembled at this time. When the battery 4 is replaced, the battery cover 2 is reset to the inner cavity of the battery slot, and the two connecting plates 8 are loosened. The adjacent plug-in plates 7 can be driven away from each other by the elastic force of the two linkage springs 9, so that the two plug-in plates 7 are respectively plugged into the inner cavities of adjacent plug-in slots, so that the battery cover 2 can be easily installed, thereby realizing rapid replacement of the battery 4, and solving the problem that the existing battery cover 2 is fixed to the meter body 1 by bolts, and when the battery 4 needs to be replaced, it is troublesome to disassemble, and it cannot be disassembled without tools, which wastes time and causes inconvenience in replacing the battery 4.
