Description

Technical Field

[0001] The utility model relates to the technical field of micro switches, in particular to an installation structure of a micro switch. Background Art

[0002] A micro switch is a switch with a tiny axial movement stroke. The minimum movement stroke of its contacts is only in the micron level. Due to the very small movement stroke of its contacts, it has the characteristics of high sensitivity, high reliability, high operating frequency, compact structure, and beautiful appearance. It is widely used in various electronic devices, such as buttons, mice, keyboards, etc. The contacts of the micro switch have extremely high insulation properties, so it is also used as a safety protection device and switch control device in many occasions. The application range of micro switches is wide, including communication equipment, computers, consumer electronics, industrial control, medical equipment and other fields, and it is an indispensable part of modern electronic equipment.

[0003] The existing micro switch installation structure is inside the device and is usually fixed by screws. However, in the actual installation process, due to the different tightening degrees of the screws, the micro switch installation position may be inaccurate, thus affecting its normal operation. In addition, after long-term use, the micro switch and the supporting parts inside the device will be under long-term pressure, and the micro switch may shift or even fall off, which may make the micro switch unusable again. Utility Model Content

[0004] The purpose of the utility model is to provide a micro switch installation structure to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A mounting structure of a micro switch comprises a micro switch body, a pressing plate is mounted on the upper end of the micro switch body, mounting mechanisms are arranged on the front and rear sides of the micro switch body, a buffer mechanism is arranged below the micro switch body, the buffer mechanism comprises a third mounting plate, a first supporting plate, a first spring, a fourth mounting plate, a second supporting plate, a second spring and a plug-in plate, a third mounting plate and a fourth mounting plate are arranged below the micro switch body, the first supporting plate is fixedly mounted on the inner wall of the third mounting plate, the first spring is fixedly mounted on the upper end of the first supporting plate, the second supporting plate is fixedly mounted on the inner wall of the fourth mounting plate, the second spring is fixedly mounted on the upper end of the second supporting plate, the plug-in plate is fixedly mounted on the rear end of the first supporting plate, and the plug-in plate is in a plug-in relationship with the second supporting plate.

[0007] Optionally, the mounting mechanism includes a first limit plate, a first clamping ring, a first iron sheet, a first mounting plate, a first limit strip, a second limit plate, a second clamping ring, a second iron sheet, a second mounting plate and a second limit strip, and a first limit plate is arranged in front of the micro switch body.

[0008] Optionally, a first clamping ring is fixedly mounted on the front end of the first limiting plate, and a first iron sheet is mounted on the first clamping ring.

[0009] Optionally, a first mounting plate is clamped at the front end of the first iron sheet, and first limiting strips are fixedly mounted on both left and right ends of the first mounting plate.

[0010] Optionally, a second limit plate is provided at the rear of the micro switch body, and a second clamping ring is fixedly mounted at the rear end of the second limit plate.

[0011] Optionally, a second iron sheet is mounted on the second clamping ring, a second mounting plate is clamped at the rear end of the second iron sheet, and second limiting strips are fixedly mounted on both left and right ends of the second mounting plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, a mounting mechanism is provided. The mounting mechanism can ensure the accurate installation position of the micro switch body in the device by using the first limit plate and the second limit plate. The insertion rods on the first limit plate and the second limit plate are directly inserted into the bolt groove on the micro switch body, and the position is limited by the first and second elastic iron sheets, which effectively avoids the problem of installation position deviation caused by different screw tightening degrees. During long-term use, the micro switch body and the supporting member are subjected to continuous pressure, which may cause deviation or falling off. The double-end limit and elastic iron sheet limit mode of the mounting mechanism can ensure that the micro switch body is firmly installed in the preset position, thereby improving durability and reliability.

[0014] 2. In the utility model, a buffer mechanism is provided. When the user presses the button on the device and starts the micro switch body, the first spring and the second spring in the buffer mechanism can absorb part of the pressure, reduce the direct impact on the micro switch body, and extend its service life. The shock-absorbing effect of the buffer mechanism can improve the user's feel when operating the micro switch, reduce noise, and make the operation smoother. At the same time, the buffer mechanism is compactly designed without adding too much volume, and is easy to integrate into various electronic devices. It is especially suitable for application scenarios with limited space. The buffer mechanism can disperse pressure, reduce the wear of the micro switch body and its support, and improve the overall durability. BRIEF DESCRIPTION OF THE DRAWINGS
