Description
Technical Field
[0001] The utility model relates to the technical field of micro switches, in particular to an assembly structure of a micro switch. Background Art
[0002] A micro switch is a switch with a small contact spacing and a snap-action mechanism. It is a contact mechanism that performs switching actions with a specified stroke and a specified force. It is covered with a shell and has a driving rod on the outside. Because the contact spacing of the switch is relatively small, it is called a micro switch, also known as a sensitive switch.
[0003] If the current micro switch is not tightly connected during connection, it will cause poor contact and cannot be used. Or, during use, the user may accidentally touch it and cause it to shift, which may also cause the micro switch to have poor contact and cannot be used.
[0004] To this end, we propose a micro switch assembly structure. Utility Model Content

[0025] Example 1
[0026] A micro switch assembly structure, such as Figure 1-Figure 3 As shown, it includes a device body 1, a limiting block 6 is slidably installed on the device body 1, at least two fixing plates 12 are fixedly installed on both sides of the lower half of the device body 1, a connecting plate 18 is inserted under the device body 1, and limiting holes 1201 are provided on the connecting plate 18 and the fixing plate 12, and the limiting holes 1201 match the limiting blocks 6. When the staff plugs the device body 1 with the connecting plate 18, the limiting holes 1201 on the fixing plate 12 are aligned with the limiting holes 1201 on the connecting plate 18, and then the staff manually slides the setting connection structure so that the limiting blocks 6 are stuck in the limiting holes 1201, so that the device body 1 is firmly connected with the connecting plate 18, so that the device body 1 will not be unable to be used due to poor contact caused by displacement during use.
[0027] like Figure 1-Figure 3As shown, at least two slide grooves 5 are provided on both side surfaces of the device body 1, and the slide grooves 5 are slidably connected to the connecting block 8 through the sliding block 15. A connecting rod 7 is fixedly installed on the lower surface of the connecting block 8, and the connecting rod 7 is fixedly connected to the limit block 6. By setting the sliding block 15, and the sliding block 15 is fixedly connected to the connecting block 8, when the staff manually slides the connecting block 8, the sliding block 15 is used to make the connecting block 8 slide in the slide groove 5, so that the slide groove 5 plays a role of sliding limit for the connecting block 8. By setting the connecting rod 7 and the limit block 6 and the connecting block 8, the staff can slide the limit block 6 at the same time when sliding the connecting block 8, so that the limit block 6 is stuck in the limit hole 1201.
[0028] Example 2
[0029] A micro switch assembly structure, such as Figure 1-Figure 3 As shown, grooves 801 are provided on both sides of the connection block 8, and a spring 13 is fixedly installed on one side surface of the groove 801, and a pressure sensor 14 is fixedly installed on the end of the spring 13 away from the groove 801. Hooks 9 are provided on both sides of the connection block 8, and a rotating shaft 10 is fixedly installed on the surface of one side of the hook 9. A driving device 11 is fixedly installed on the end of the rotating shaft 10 away from the hook 9. The rotating shaft 10 extends to the inside of the device body 1, and the rotating shaft 10 is rotatably connected to the device body 1. When the staff manually pulls the connection block 8, the pressure sensor 14 feels a pressure once, and the connection block 8 will not move at this time. When the staff pulls the connection block 8 again, the pressure sensor 14 will sense the pressure again and send a pressure signal to the control terminal. The control terminal sends a signal, and the control terminal sends an electrical signal to the driving device 11, so that the driving device 11 works, and the two driving devices 11 move in opposite directions, so that the rotating shaft 10 opens outward, so that the hook 9 moves in the direction away from the connecting block 8, so that the connecting block 8 can move downward, so that the limit block 6 can be stuck in the limit hole 1201. When the staff needs the hook 9 to hook the connecting block 8, the connecting block 8 is pulled in the opposite direction of the fixed plate 12, and then the switch of the driving device 11 is turned on, so that the driving device 11 is reversed, so that the hook 9 moves in the direction close to the connecting block 8, so that the hook 9 hooks the connecting block 8.
[0030] like Figure 1-Figure 4As shown, a switch spring piece 2 is rotatably mounted on the upper end of the device body 1, a contact roller 3 is rotatably mounted on one end of the switch spring piece 2, a No. 2 spring 4 is fixedly mounted on the lower surface of the switch spring piece 2, and the No. 2 spring 4 is fixedly connected to the device body 1 at one end away from the switch spring piece 2, and a mounting plate 16 is threadedly screwed with a bolt 17 at the lower end of the device body 1, and a contact piece 19 is fixedly mounted on the lower end of the mounting plate 16, and the contact piece 19 passes through the mounting plate 16 and extends to the outside of the device body 1. By providing the mounting plate 16, and the mounting plate 16 and the device body 1 are threadedly screwed together with the bolt 17, when the contact piece 19 is damaged, the staff screws the bolt 17 to separate the mounting plate 16 from the device body 1, thereby separating the contact piece 19 from the device body 1, so that the staff can easily replace the contact piece 19.
[0031] Working principle: When the staff plugs the device body 1 with the connecting plate 18, the limiting hole 1201 on the fixing plate 12 is aligned with the limiting hole 1201 on the connecting plate 18. Then the staff manually slides the connection structure to make the limiting block 6 snap into the limiting hole 1201, so that the device body 1 is firmly connected with the connecting plate 18, so that the device body 1 will not be unusable due to poor contact caused by displacement during use. At the same time, when the staff manually pulls the connecting block 8, the pressure sensor 14 feels the pressure once, and the connecting block 8 will not move. When the staff pulls the connecting block 8 again, the pressure sensor 14 will sense the pressure again and move to the control The control terminal sends a signal, and the control terminal sends an electrical signal to the drive device 11, so that the drive device 11 works, and the two drive devices 11 move in opposite directions, so that the rotating shaft 10 opens outward, so that the hook 9 moves in the direction away from the connecting block 8, so that the connecting block 8 can move downward, so that the limit block 6 can be stuck in the limit hole 1201. When the staff needs the hook 9 to hook the connecting block 8, the connecting block 8 is pulled in the opposite direction of the fixed plate 12, and then the switch of the drive device 11 is turned on, so that the drive device 11 is reversed, so that the hook 9 moves in the direction close to the connecting block 8, so that the hook 9 hooks the connecting block 8.
