DETAILED DESCRIPTION

[0024] The utility model will now be described in further detail with reference to the accompanying drawings.

[0025] See also Figure 1-3 As shown, in this embodiment, a micro switch that is easy to disassemble and maintain is provided, including a connecting plate 2, a micro switch body 1 placed on the side of the connecting plate 2, and a clamping block 101 is installed on both sides of the micro switch body 1;

[0026] The side of the connecting plate 2 is elastically matched with an L-clip 3 and a tilted triangle 4 corresponding to the card block 101. The microswitch body 1 is located between the two L-clip 3. The L-clip 3 opens upward. The tilted triangle 4 is located on the upper side of the card block 101. The card block 101 and the tilted triangle 4 are both located inside the L-clip 3. The height of the L-clip 3 is greater than the sum of the heights of the card block 101 and the tilted triangle 4.

[0027] One aspect of the application of this embodiment is: during installation, the micro switch body 1 is placed at a position higher than the L clamp 3 and attached to the connecting plate 2, and then the micro switch body 1 is slid downward to make the clamp 101 slide into the L clamp 3. When the lower side of the clamp 101 contacts the inclined surface of the tilted bottom triangle 4, the clamp 101 squeezes the L clamp 3 and slides in the direction away from the connecting plate 2. The micro switch body 1 and the clamp 101 are also guided away from the connecting plate 2 by the tilted bottom triangle 4. When the bottom of the clamp 101 contacts the L clamp 3, the clamp 101 moves away from the connecting plate 2. When it is unable to move downward any further, release the microswitch body 1, and then the L card member 3 is driven by the elastic force to move the card block 101 toward the connecting plate 2 to fit together, and at the same time, the card block 101 is squeezed upward from the bottom raised position of the tilted triangle member 4, so that the tilted triangle member 4 is pressed on the card block 101 by the elastic force, thereby achieving the installation and fixation of the microswitch body 1. Similarly, the microswitch body 1 can be quickly disassembled by referring to the above operation, first pulling the microswitch body 1 away from the connecting plate 2, and finally pulling it upward to complete the disassembly.

[0028] The L clamp 3 of this embodiment includes an extrusion plate 301 elastically fitted in the connecting plate 2, a horizontal plate 302 is installed at the lower part of the side of the extrusion plate 301, and a vertical plate 303 is installed on the upper side of one end of the horizontal plate 302. The clamping block 101 is located on the upper side of the horizontal plate 301, and the clamping block 101 and the tilted bottom triangle piece 4 are located between the vertical plate 303 and the connecting plate 2. The height of the vertical plate 303 is greater than the sum of the heights of the clamping block 101 and the tilted bottom triangle piece 4, so that the clamping block 101 is first inserted between the vertical plate 303 and the connecting plate 2, and then contacts and squeezes with the tilted bottom triangle piece 4, thereby improving the convenience of installation of the micro switch body 1, and reducing the probability of the L clamping member 3 detaching from the connecting plate 2 through the extrusion plate 301.

[0029] The connecting plate 2 of the present embodiment is provided with a groove 201 corresponding to the transverse plate 302 on one side, and one end of the transverse plate 302 is slidably fitted in the groove 201, and a transverse sliding groove 202 corresponding to the extrusion plate 301 is provided on the upper side of the inner wall of the groove 201, and the upper part of the extrusion plate 301 is slidably fitted in the transverse sliding groove 202, and a plurality of first rod bodies 203 are installed between the two sides of the inner wall of the transverse sliding groove 202, and the first rod body 203 passes through the extrusion plate 301 in the transverse direction, and a first spring 5 sleeved on the periphery of the first rod body 203 is provided between the extrusion plate 301 and one side of the inner wall of the transverse sliding groove 202, and the first spring 5 is located between the block 101 and the extrusion plate 301, and the stability of the extrusion plate 301 when sliding is improved by the first rod body 203, while the probability of the first spring 5 being squeezed by the extrusion plate 301 and being dislocated is reduced.

[0030] In this embodiment, a first rubber pad 304 is installed on one side of the vertical plate 303 adjacent to the connecting plate 2, and a second rubber pad 7 corresponding to the block 101 is installed on one side of the connecting plate 2. The second rubber pad 7 is located on the lower side of the tilted bottom triangle 4, and the block 101 is located between the first rubber pad 304 and the second rubber pad 7. The first rubber pad 304 cooperates with the second rubber pad 7 to improve the firmness of the clamping of the vertical plate 303 and the connecting plate 2 on the block 101, and reduce the probability of shaking of the block 101 after clamping.

[0031] The tilted bottom triangle member 4 of this embodiment includes a slide 403 elastically fitted in the connecting plate 2, a right-angled triangle block 401 is installed on the side of the slide 403, the right-angled triangle block 401 is slidably fitted on the side of the connecting plate 2, the right-angled triangle block 401 is located on the upper side of the clamping block 101, and an extrusion groove 402 is provided at the edge of the lower side of the right-angled triangle block 401 near the vertical plate 303. Through the extrusion groove 402, the edge of the lower part of the right-angled triangle block 401 near the vertical plate 303 is higher than the upper side of the clamping block 101, so that the clamping block 101 is squeezed into the lower side of the right-angled triangle block 401.

[0032] A vertical slide groove 204 corresponding to the slide cylinder 403 is provided on one side of the connecting plate 2 of the present embodiment. The slide cylinder 403 slides in the vertical slide groove 204. A second rod body 205 is installed between the upper and lower ends of the inner wall of the vertical slide groove 204. The slide cylinder 403 is sleeved on the peripheral side of the second rod body 205. A second spring 6 sleeved on the peripheral side of the second rod body 205 is provided between the slide cylinder 403 and the upper end of the inner wall of the vertical slide groove 204. The second rod body 205 reduces the probability of the slide cylinder 403 escaping from the vertical slide groove 204, and at the same time reduces the probability of the second spring 6 being squeezed by the slide cylinder 403 and being dislocated.
