Description

Technical Field

[0001] The utility model relates to the field of gear switches, in particular to a gear switch with an anti-loosening base. Background Technique

[0002] A gear switch is an electronic component used to control a circuit. Common gear switches are push-type and rotary-type, and are widely used in real life.

[0003] CN215731377U discloses a gear switch with an anti-loosening base, including a mounting base. Ear plates are symmetrically fixed on the side of the mounting base, and the ear plates are penetrated by fixing bolts. At the same time, a movable ring is arranged at the upper end of the ear plate, and the movable ring is also penetrated by the fixing bolt; it also includes: a switch body arranged in the mounting base, a button is arranged at the upper end of the switch body, and the switch body is connected to an external device through a connecting wire.

[0004] For this gear switch with an anti-loosening base, by using bolts in cooperation with an anti-slip limit mechanism, the installation and fixation of the mounting base can be realized, thereby avoiding the loosening of bolts caused by long-term use and ensuring the stability of fixation. The sliding elastic sealing mechanism can realize the sealing effect on the switch body, and the linkage lifting mechanism can realize the storage effect on the switch body, thereby avoiding the situation that the switch body adheres to dust and is accidentally touched.

[0005] However, the gear switch needs to be installed in a fixed position for a long time. The cited patent uses the cooperation relationship between gears and threaded rods to achieve linkage. In the short term, this design can meet the requirements of linkage. However, after a period of time, the threaded rod will get stuck, and although the anti-reverse bolts can play an anti-loosening effect, the connection between the gear switch and the base also needs to be strengthened.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] It should be noted that all the directional indications in the embodiments of the present application are only used to explain the relative position relationship and movement conditions between components in a specific posture. If this specific posture changes, the directional indications will also change accordingly.

[0029] The embodiment of the present invention provides a gear switch with an anti-loosening base:

Two groups of positioning mechanisms 3 are fixedly installed on the sides of the switch body 2. The switch body 2 is slidably connected to the inner wall of the installation base 1 through the positioning mechanisms 3. A bottom plate 4 is fixedly installed at the closed end of the installation base 1. Locking mechanisms 5 are installed on the sides of the installation base 1.

[0031] The switch body 2 is provided with buttons and is connected to an external device through a connecting wire. The installation base 1 is a deep groove structure.

[0032] The outermost ends of the locking mechanisms 5 are flush with the side of the bottom plate 4. There are four locking mechanisms 5, which are respectively located on the four sides of the installation base 1.

[0033] Thus, the four locking mechanisms 5 are connected to the grooved positions of the external device.

[0034] The locking mechanism 5 includes a clamping plate 501, a triangular plate 502, a U-shaped plate 503 and a screw 504. Two chutes 505 are provided at one end of the clamping plate 501 close to the installation base 1. The chutes 505 cooperate with the ends of the U-shaped plate 503 for sliding. The clamping plate 501 is also provided with a triangular groove 506, which is located between the two chutes 505. The screw 504 is longitudinally installed in the middle position of the U-shaped plate 503 and is rotatably connected to the U-shaped plate 503. The triangular plate 502 is located inside the U-shaped plate 503. The bottom end of the screw 504 is embedded in the triangular plate 502 and is threadedly connected to it. The triangular groove 506 corresponds to the triangular plate 502. When the triangular plate 502 moves down, it squeezes the clamping plate 501 through the triangular groove 506.

[0035] When the clamping plate 501 is not in use, it can be removed from the U-shaped plate 503. When in use, it only needs to be snapped in. Then, the triangular plate 502 can slowly squeeze the clamping plate 501 under the action of the screw 504.

[0036] Two sliding rods slidably connected to the screw 504 are also provided on the U-shaped plate 503 outside the screw 504. The other ends of the sliding rods are fixed to the triangular plate 502.

[0037] The sliding rods are mainly provided to ensure that the triangular plate 502 can only move longitudinally.

[0038] The bottom of the end of the clamping plate 501 away from the installation base 1 is a bevel structure, and the bottom end of the clamping plate 501 is an arc structure. A stop bar 6 is fixedly installed at the position of the bottom plate 4 corresponding to the bottom end of the clamping plate 501.

[0039] The arc structure at the bottom end of the clamping plate 501 facilitates its swinging with the bottom end as the fulcrum, and the stop bar 6 is mainly used to fix this fulcrum to achieve the effect of resistance.

[0040] The positioning mechanism 3 includes a slider 301, a guide rail 302 and a spring 303. The slider 301 is located within the guide rail 302 and is slidably connected thereto.

One end of the spring 303 is fixed to the slider 301, and the other end of the spring 303 is fixed to the switch body 2.

[0041] Lubricating grease is applied between the slider 301 and the guide rail 302, which will not fail after long-term use. The spring 303 increases the contact force between the slider 301 and the guide rail 302 and supports the switch body 2 to buffer the switch body 2.

[0042] A partition 7 is magnetically attracted and installed at the opening position of the mounting base 1, and the partition 7 and the mounting base 1 are hermetically arranged.

[0043] The partition 7 is installed by magnetic attraction, and a magnetic strip can be installed at the open end of the mounting base 1.

[0044] The area of the bottom plate 4 is larger than the cross-sectional area of the mounting base 1. Positioning holes 8 are provided in a circle on the outside of the bottom plate 4 where it is located outside the mounting base 1.

[0045] During use, the whole is installed in an embedded manner. The equipment to be installed needs to be grooved, and the grooving area is equal to the area of the bottom plate 4. Then the bottom plate 4 is connected to the external equipment by bolts. Anti-loosening bolts can be used for the bolts. After the bottom plate 4 is connected, the four clamping plates 501 are respectively inserted into the four U-shaped plates 503, and then the screw rod 504 is tightened to make the triangular plate 502 slowly push the clamping plate 501, and then gradually make the clamping plate 501 contact the side wall of the external equipment to achieve extrusion fixation. The four clamping plates 501 apply force at the same time, and the four surfaces of the mounting base 1 are well fixed. The partition 7 is magnetically attracted to the mounting base 1 and is located outside. It can isolate dust in daily life, and it is very convenient to remove. Just uncover it. Moreover, after opening, the switch body 2 can be directly pulled out from the mounting base 1, which is convenient for operation and maintenance and will not get stuck due to long-term non-use.
