Description

Technical Field

[0001] This utility model relates to a safety door switch that is easy to install. Background Technology

[0002] Safety door switches are key components for the safety protection of industrial equipment, used to detect the status of safety doors and control the start and stop of equipment.

[0003] Traditional safety door switches generally suffer from problems such as complex installation and difficult maintenance: the lack of anti-slip design on the outer shell causes slippage during installation, the fixed structure relies on overall disassembly, affecting maintenance efficiency, and the insufficient precision of the keyhole and operating key can easily cause operation jamming or accidental triggering, reducing safety and ease of use. Utility Model Content

[0004] The purpose of this invention is to provide a safety door switch that is easy to install, so as to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An easy-to-install safety door switch includes a switch housing, an anti-slip groove, a bottom hole, a switch head, an operating keyhole, and an operating key. The anti-slip groove is provided on the upper outer side of the switch housing. The bottom hole is located at the bottom of the switch housing. The switch head is axially connected to the upper part of the switch housing. The operating keyhole is located at the top of the switch head. The operating key is matched and inserted into the operating keyhole.

[0007] Based on the above technical solution, the switch housing includes a head shaft, a side plate, side plate screws, and a snap-fit ​​end. The head shaft is fixedly connected to the bottom of the switch head and threadedly connected to the top of the switch housing. The side plate is connected to the outside of the switch housing by three side plate screws, and the snap-fit ​​end is fixedly connected to the top of the side plate.

[0008] Based on the above technical solution, the operating key includes a body, a convenience hole, and a snap-fit ​​groove. Two convenience holes are equally spaced at the rear interior of the body, and the snap-fit ​​groove is located inside the front interior of the body.

[0009] Compared with the prior art, this utility model has the following advantages: The anti-slip groove enhances the installation grip, the side plate uses three side plate screws for quick assembly and disassembly, and the snap-fit ​​end forms a stable connection with the snap-fit ​​groove of the operating key. The operating key has a convenient hole for hanging and carrying, the switch head can rotate flexibly through a head pivot, and the bottom hole provides multiple wiring options. The overall structure combines ease of installation, operational stability, and economical maintenance. Attached Figure Description

[0011] Figure 2 This is a schematic diagram of the switch housing structure of this utility model.

[0012] Figure 3 This is a schematic diagram of the operating key structure of this utility model.

[0013] In the diagram: 1. Switch housing, 2. Anti-slip groove, 3. Bottom hole, 4. Switch head, 5. Operating key hole, 6. Operating key, 7. Head pivot, 8. Side plate, 9. Side plate screw, 10. Snap-fit ​​end, 11. Body, 12. Convenience hole, 13. Snap-fit ​​groove. Detailed Implementation

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] like Figure 1-3 As shown, a safety door switch that is easy to install includes a switch housing 1, an anti-slip groove 2, a bottom hole 3, a switch head 4, an operating keyhole 5, and an operating key 6. The anti-slip groove 2 is provided on the upper outer side of the switch housing 1. The bottom hole 3 is provided below the switch housing 1. The switch head 4 is axially connected to the upper part of the switch housing 1. The operating keyhole 5 is provided above the switch head 4. The operating key 6 is matched and inserted into the operating keyhole 5.

[0016] The switch housing 1 includes a head pivot 7, a side plate 8, side plate screws 9, and a snap-fit ​​end 10. The head pivot 7 is fixedly connected to the bottom of the switch head 4 and threadedly connected to the top of the switch housing 1. The side plate 8 is bolted to the outside of the switch housing 1 by three side plate screws 9. The snap-fit ​​end 10 is fixedly connected to the top of the side plate 8.

[0017] The operating key 6 includes a body 11, a convenience hole 12, and a snap-fit ​​groove 13. Two convenience holes 12 are equally spaced at the rear interior of the body 11, and the snap-fit ​​groove 13 is located inside the front end of the body 11.

[0018] The working principle of this utility model is as follows: During operation, the operating key 6 is inserted into the operating keyhole 5 of the switch head 4, causing the switch head 4, connected via the head shaft 7, to rotate. Side plate screws 9 fix the side plate 8 to the switch housing 1, forming a rigid support. The anti-slip groove 2 provides installation torque, and the bottom hole 3 penetrates the bottom of the housing to secure the cable. After the key is removed, the switch head 4 automatically resets, and the shaft connection structure ensures smooth operation.

[0019] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
