[0020] 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.

[0021] Reference Figure 1-5 A pressure monitoring sensor with a built-in battery comprises a sensor body 2 arranged on the end face of a base 1, the base 1 is fixedly connected to the sensor body 2, and a mounting groove 3 is arranged on its side, the base 1 is located at the opening of the mounting groove 3 and is provided with a movable plate 6 through a clamping member 5, the movable plate 6 can close the mounting groove 3, and a button battery 4 is arranged on the end face of the movable plate 6 through a fixing member 7.

[0022] Furthermore, a circuit board 31 and a positive terminal 32 are provided in the mounting groove 3, and a negative terminal 33 is provided on the end surface of the movable plate 6. The positive terminal 32 and the negative terminal 33 are electrically connected to the positive and negative poles of the button battery 4 respectively, and are connected to the circuit board 31 through a wire 34.

[0023] It should be supplemented that electronic components are provided inside the sensor body 2 , the circuit board 31 is electrically connected to the electronic components, and the button battery 4 can provide power to the sensor body 2 through the positive terminal 32 and the negative terminal 33 .

[0024] Furthermore, the clamping member 5 includes a fixed plate 51, the movable plate 6 is rotatably connected to the mounting groove 3 via a rotating shaft 61, and a torsion spring 62 is arranged inside the movable plate 6 and on the periphery of the rotating shaft 61, and both ends of the torsion spring 62 are respectively fixedly connected to the movable plate 6 and the side of the mounting groove 3, and the fixed plate 51 is fixedly installed at one end of the rotating shaft 61.

[0025] In detail, under the action of the torsion spring 62, the movable plate 6 and the mounting groove 3 are separated at an acute angle, and then the movable plate 6 is flipped over and under the action of the clamp 5, the movable plate 6 is closed and fixed, thereby ensuring that the button battery 4 can be fixed in the mounting groove 3, and the sensor body 2 is powered by the positive terminal 32 and the negative terminal 33.

[0026] In more detail, a slide groove 11 is provided at the bottom of the base 1 next to the mounting groove 3, and the rotating shaft 61 is provided with one end of the fixed plate 51 which rotates in the slide groove 11, and one end of the rotating shaft 61 is also slidably connected to a movable plate 52, and a first spring 53 is provided on its outer periphery, and the two ends of the first spring 53 are respectively fixedly connected to the slide groove 11 and the movable plate 52, and the fixed plate 51 and the movable plate 52 are respectively provided with a protrusion 511 and a recessed portion 521 on the facing sides, and the protrusion 511 can be inserted into the recessed portion 521, and an unlocking block 522 is provided on the top of the movable plate 52.

[0027] It should be noted that the unlocking block 522 is slidably connected to the movable plate 6, and the movable plate 52 is moved by pushing the unlocking block 522, so that the recessed portion 521 is separated from the raised portion 511, and the movable plate 6 loses the fixing effect of the recessed portion 521 and turns over under the action of the torsion spring 62;

[0028] Among them, the protrusions 511 are symmetrically arranged in a pair, and the recessed portions 521 are adjacently arranged in two pairs, one pair of the recessed portions 521 stops the protrusions 511 when the movable plate 6 is closed, and the other pair of the recessed portions 521 stops the protrusions 511 after the movable plate 6 is flipped over, thereby preventing the movable plate 6 from rotating at will when the button battery 4 is disassembled and assembled.

[0029] In addition, the first spring 53 provides elastic support for the movable disk 52, so that the movable disk 52 can return to its original position after being pushed.

[0030] In general, the fixing member 7 includes a pair of metal springs 71, and the end surface of the movable plate 6 is fixedly connected to the pair of metal springs 71 through a fixing seat 63. An arc portion 72 is arranged opposite to each other between the pair of metal springs 71, and the button battery 4 can be clamped through the arc portion 72. The base 1 is located below the negative terminal 33 and is provided with a groove 73, and a release member 8 is provided in the groove 73.

[0031] The specific operation is to fix the button battery 4 in the pair of arc-shaped portions 72 by pressing, and the pair of metal springs 71 clamp and fix the button battery 4 through the arc-shaped portions 72, and the pair of metal springs 71 are arranged above the negative terminal 33;

[0032] Considering that the pair of metal springs 71 have good toughness and can clamp the button battery 4 , it is inconvenient to remove the button battery 4 , and the release member 8 is required to remove the button battery 4 .

[0033] Finally, the disengagement member 8 includes a push rod 81, which is rotatably connected to the base 1, and one end of which is located in the groove 73 and is provided with a flip portion 82, and the other end is provided with a pressing portion 83. The flip portion 82 avoids the negative terminal 33 from contacting the bottom of the button battery 4 through a through groove 84, and a second spring 85 is fixedly connected between the pressing portion 83 and the movable plate 6.

[0034] The specific operation is to use the through groove 84 to prevent the flip part 82 from interfering with the negative terminal 33, and after the button battery 4 is pressed into a pair of the arc-shaped parts 72, it will interfere with the flip part 82, and then the pressing part 83 is pressed to drive the flip part 82 to tilt up and drive the button battery 4 to detach.

[0035] It should be noted that the flip portion 82 is disposed below the pair of metal spring sheets 71 , and the flip portion 82 is smaller than the pair of metal spring sheets 71 to prevent the flip portion 82 from contacting the metal spring sheets 71 when flipping.

[0036] Working method: When working, the unlocking block 522 is pushed to drive the movable disk 52 to move. After the movable disk 52 moves, the recessed portion 521 will be separated from the raised portion 511, and the movable plate 6 loses the clamping and fixing of the movable disk 52 and flips under the action of the torsion spring 62. Then, under the action of the first spring 53, the movable disk 52 returns to its original position, and the other pair of recessed portions 521 will clamp and fix the movable plate 6 with the raised portion 511, so as to facilitate the replacement of the button battery 4.

[0037] Then, the pressing portion 83 is pressed to cause the flipping portion 82 to flip. The flipping portion 82 contacts the bottom of the button battery 4 and flips to cause the button battery 4 to break away from the fixation of the pair of metal springs 71 .

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
