Description

Technical Field

[0001] This utility model relates to the field of pull cord switch technology, specifically to a novel pull cord switch. Background Technology

[0002] Existing pull-cord switches are typically simple in structure and single in function, lacking a reliable locking mechanism, and are prone to instability in their switch state due to accidental activation or external force. Furthermore, the conductive components of existing switches are susceptible to wear from frequent operation, affecting their lifespan.

[0003] Therefore, there is an urgent need for a new type of pull cord switch that is structurally stable, has a locking function, and is durable. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a new type of pull cord switch. By optimizing the structural design and adding a locking device and conductive disk mechanism, the problems of poor stability, easy accidental activation and insufficient durability of existing switches are solved.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] The new pull cord switch includes:

[0007] The switch housing includes a matching rear housing and a front housing, which are assembled together by screws;

[0008] The transformer is mounted and fixed inside the rear housing, and contact conductive plates are movably installed on the side of the transformer.

[0009] The conductive disk, the rotating shaft, and the torsion spring are arranged in a one-to-one correspondence with the contact conductive sheet. After being sleeved and fixed onto the rotating shaft, the rotating shaft is rotatably connected to the middle shell wall of the rear housing. The conductive disk is also connected to the inner bottom wall of the rear housing through the torsion spring through which the rotating shaft passes. When the conductive disk rotates clockwise, it abuts against the contact conductive sheet. When it rotates counterclockwise, it moves away from the contact conductive sheet. The rear end of the rotating shaft extends to the outer shell of the rear housing and a wrench is fixed thereon.

[0010] The lock is installed inside the rear housing. When the conductive plate comes into contact with the contact conductive sheet, the lock is locked and the conductive plate and contact conductive sheet cannot be separated. When the lock is unlocked, the conductive plate and contact conductive sheet can be separated.

[0011] As an improvement, a pair of conductive discs are arranged along the axial direction of the rotating shaft, and a corresponding pair of contact conductive plates are also arranged. The lock includes a lock body, a lock cylinder, and a bolt; the lock body is embedded and installed on the left side wall of the rear housing, the lock cylinder is an L-shaped plate, and one side plate is rotatably connected to the end of the lock cylinder, the bolt is an L-shaped plate with one side plate forming a disc body structure adapted to the shape of the conductive disc, and is fixed to the conductive disc on the rear side by screws, the side plates of the bolt and the lock cylinder that are not fixedly connected are perpendicular to each other, and before and after the lock cylinder rotates 90°, the lock cylinder either blocks or does not block the rotation of the bolt.

[0012] As an improvement, a wire hole is provided on the right side of the rear housing. The wires connected to the transformer pass through the wire hole, and the connection between the wire and the wire hole is well sealed.

[0013] The advantages of this utility model compared with the prior art are: This utility model

[0014] 1. High stability: The locking design ensures that the conductive disk and the contact conductive sheet cannot be separated in the locked state, avoiding accidental contact or external interference.

[0015] 2. High durability: The mating structure of the conductive disk and the contact conductive sheet reduces wear and extends service life.

[0016] 3. Easy installation: The mounting feet and wiring holes facilitate fixing and wiring, improving practicality. Attached Figure Description

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

[0025] The new pull cord switch includes:

[0026] The switch housing includes a matching rear housing 1 and a front housing 2, which are assembled together by screws. A pair of left and right mirror-arranged mounting feet 12 are fixed to the bottom of the rear housing 1.

[0027] Transformer 3 is mounted and fixed inside the rear housing 1. Contact conductive sheet 4 is movably arranged on the side of transformer 3. A wire hole 11 is also reserved on the right side of the rear housing 1. The wires connected to transformer 3 pass through the wire hole 11.

[0028] The system comprises a conductive disk 5, a rotating shaft 6, and a torsion spring 7. The conductive disk 5 is configured one-to-one with the contact conductive piece 4, and is sleeved and fixed onto the rotating shaft 6. The rotating shaft 6 is rotatably connected to the middle shell wall of the rear housing 1. The conductive disk 5 is also connected to the inner bottom wall of the rear housing 1 via the torsion spring 7 through which the rotating shaft 6 passes. When the conductive disk 5 rotates clockwise, it contacts the contact conductive piece 4; when it rotates counterclockwise, it moves away from the contact conductive piece 4. A wrench is fixed to the rear end of the rotating shaft 6 extending to the outer shell of the rear housing 1. A pair of conductive disks 5 are arranged along the axial direction of the rotating shaft 6, and a corresponding pair of contact conductive pieces 4 are also arranged.

[0029] The lock includes a lock body 8, a lock cylinder 9, and a bolt 10. The lock body 8 is embedded in the left side wall of the rear housing 1. The lock cylinder 9 is an L-shaped plate, and one side plate is rotatably connected to the end of the lock cylinder 9. The bolt 10 is an L-shaped plate, and one side plate forms a disc structure that matches the shape of the conductive disk 5. It is fixed to the conductive disk 5 on the rear side by screws. The side plates of the bolt 10 and the lock cylinder 9 that are not fixedly connected are perpendicular to each other. When the lock cylinder 9 rotates 90°, the lock cylinder 9 either blocks or does not block the rotation of the bolt 10.

[0030] In the specific implementation of this embodiment:

[0031] The lock is equipped with a key, which can be used to rotate the lock cylinder 9 by 90°. After the conductive plate 5 contacts the conductive contact piece 4, the switch is energized. At this time, rotating the lock cylinder 9 to the desired position... Figure 3 and 4 In the state shown, the conductive disk 5 can no longer rotate, and the switch is kept energized. When the lock cylinder 9 is turned clockwise, it will no longer block the rotation of the conductive disk 5. At this time, the conductive disk 5 can be separated from the contact conductive piece 4, thus achieving power off.
