Description

Technical Field

[0001] This utility model relates to the field of switch technology, specifically to a securely mounted flat button switch. Background Technology

[0002] A flat-top switch is a manual control switch with a flat top. It is a common type of flat-top switch. Its core function is to switch the circuit on or off by pressing it. It is widely used in various electronic devices and electrical control scenarios.

[0003] When installing existing push-button switches, the main body of the switch is usually inserted into the pre-set mounting hole on the equipment. Then, the internally threaded fastening sleeve is screwed into the external thread of the switch body and tightened. The push-button switch and the fastening sleeve are clamped together to secure the switch. However, when installed on equipment that generates frequent vibrations, such as machine tools and vibrating screens, the threaded connection between the fastening sleeve and the push-button switch is prone to loosening under long-term vibration, resulting in an unstable installation. Utility Model Content

[0004] The purpose of this invention is to provide a securely installed flat toggle switch to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a securely installed flat toggle switch, comprising a base shell, a fastening sleeve threaded to the outside of the base shell, a flat button slidably mounted on the base shell, an extension portion integrally formed on the top of the base shell, a housing threaded to the outside of the extension portion, and a transmission mechanism and a contact mechanism disposed inside the base shell. The bottom of the contact mechanism is provided with a terminal block, and the terminal block extends to the outside of the base shell. The outside of the base shell is symmetrically provided with elastic arms. The inner sidewall of the fastening sleeve is provided with an annular groove that mates with the elastic arms. The bottom edge of the extension portion is symmetrically provided with a plurality of first ratchet teeth. The bottom of the inner sidewall of the housing is uniformly provided with second ratchet teeth that mate with the first ratchet teeth along the circumferential direction.

[0006] As a preferred embodiment of this utility model, the outer side of the fastening sleeve is provided with a protrusion.

[0007] In a preferred embodiment of this utility model, the diameter of the extension portion is larger than the diameter of the bottom shell.

[0008] As a preferred embodiment of this utility model, the elastic arm and the bottom shell are integrally formed.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting an elastic arm and an annular groove, when the fastening sleeve becomes loose due to equipment vibration and tends to move downward, the elastic arm will block the fastening sleeve and restrict its downward movement, thereby preventing the fastening sleeve from loosening and ensuring that the flat button switch is installed firmly. Furthermore, by setting a second ratchet and a first ratchet, when the outer shell tends to rotate counterclockwise and loosen, the first ratchet will block the movement of the second ratchet, thereby preventing the outer shell from loosening and ensuring that the outer shell can be firmly installed on the outside of the extension part.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 8This utility model provides a technical solution: a securely installed flat button switch, including a base shell 1, a fastening sleeve 4 threaded to the outside of the base shell 1, a flat button cap 3 slidably mounted on the base shell 1, an extension portion 7 integrally formed on the top of the base shell 1, a shell 2 threaded to the outside of the extension portion 7, and a transmission mechanism 8 and a contact mechanism 9 disposed inside the base shell 1. When the flat button cap 3 is pressed down, the flat button cap 3 transmits the action to the contact mechanism 9 through the transmission mechanism 8. Driven by this action, the contact mechanism 9 is triggered, causing its internal contacts to activate. The displacement enables the switching of the circuit's on / off state. The transmission mechanism 8 and contact mechanism 9 are conventional technologies in this field and will not be described in detail. The bottom of the contact mechanism 9 is provided with a terminal 6 for connecting to external wires, and the terminal 6 extends to the outside of the bottom shell 1. Symmetrically arranged on the outside of the bottom shell 1 are elastic arms 10, which are inclined. When the fastening sleeve 4 is gradually tightened on the outside of the bottom shell 1, it moves towards the extension part 7. During this process, the elastic arms 10 are squeezed by the fastening sleeve 4 towards the bottom shell 1. When the fastening sleeve 4 is tightened, the elastic arm 10 aligns with the annular groove 12. The elastic arm 10 then springs back and engages with the annular groove 12. When the fastening sleeve 4 tends to loosen and move downwards, the elastic arm 10 will block the fastening sleeve 4 from moving downwards, preventing the fastening sleeve 4 from loosening and ensuring that the flat switch is securely installed. The inner wall of the fastening sleeve 4 has an annular groove 12 that mates with the elastic arm 10. The bottom edge of the extension 7 is symmetrically provided with multiple first ratchet teeth 11. The bottom of the inner arm of the outer casing 2 is uniformly provided with second ratchet teeth 11 along the circumferential direction. When the outer casing 2 is tightened clockwise on the outside of the extension 7, the outer casing 2 drives the second ratchet 13 to rotate. At this time, the guide surface of the second ratchet 13 contacts the guide surface of the first ratchet 11. The first ratchet 11 will not block the movement of the second ratchet 13. When the outer casing 2 has a tendency to loosen by rotating counterclockwise, the locking surface of the second ratchet 13 contacts the locking surface of the first ratchet 11. The first ratchet 11 will block the movement of the second ratchet 13, thereby preventing the outer casing 2 from rotating counterclockwise and ensuring that the outer casing 2 can be firmly installed on the outside of the extension 7.

[0021] The fastening sleeve 4 has a protrusion 5 on its outer side. The protrusion 5 is used to increase the friction between the hand and the fastening sleeve 4, effectively preventing the operator from slipping when tightening the fastening sleeve 4 due to insufficient friction on the contact surface.

[0022] The diameter of the extension part 7 is larger than the diameter of the bottom shell 1, so that when the bottom shell 1 passes through the preset mounting hole on the device, the extension part 7 cannot pass through the mounting hole so that the extension part 7 can cooperate with the fastening sleeve 4 to clamp the device.

[0023] The elastic arm 10 and the bottom shell 1 are integrally molded. The integral molding structure ensures that the elastic arm 10 and the bottom shell 1 are firmly connected and facilitates manufacturing. Both the elastic arm 10 and the bottom shell 1 are made of plastic, which gives the elastic arm 10 a certain degree of elasticity.

[0024] Specifically, during installation, the base shell 1 is passed through the hole on the equipment until one side of the extension 7 is pressed against the equipment. Then, the fastening sleeve 4 is screwed onto the outside of the base shell 1. The fastening sleeve 4 is gradually tightened, and it moves closer to the extension 7. During this process, the inner wall of the fastening sleeve 4 squeezes the elastic arm 10, forcing the elastic arm 10 to elastically deform towards the center of the base shell 1. When the fastening sleeve 4 is tightened and engages with the extension 7 to clamp the equipment, the elastic arm 10 aligns with the annular groove 12 on the outside of the base shell 1. At this time, the elastic arm 10 resets and springs open, locking into the annular groove 12. When the equipment vibrates, causing the fastening sleeve 4 to loosen and tend to move downwards, the elastic arm 10 will block the fastening sleeve 4, limiting its downward movement, thereby effectively preventing the fastening sleeve 4 from loosening and ensuring that the flat switch always maintains a stable installation state.
