Description

Technical Field

[0001] This utility model belongs to the field of safety switch technology, specifically relating to a quick-connect safety switch. Background Technology

[0002] Safety switches are crucial protective devices for washing machines, primarily used for: preventing accidental start-up: When the washing machine door is not closed or locked, the safety switch disconnects the circuit, preventing the motor from starting and avoiding danger. Emergency stop: If the user opens the door during the washing process, the safety switch immediately cuts off the power supply to ensure user safety. Status monitoring: By providing feedback on the door lock status through the switch signal, it assists the washing machine control system in achieving automated operation. Traditional household appliance door control safety switches, when in use, require significant disassembly of many fixed components to replace them if a malfunction occurs after installation, making subsequent maintenance and replacement difficult and relatively inefficient. Utility Model Content

[0022] 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.

[0023] Please see Figures 1-6 As shown, this utility model provides the following technical solution:

[0024] A quick-connect safety switch includes a trigger 1 and a switch 2. The trigger 1 includes a pre-fixed first base plate 11. One side of the first base plate 11 is open to form a slot 12. A pluggable plug 19 is disposed inside the slot 12. An elastic sheet 111 is fixedly connected to one side of the plug 19. One side of the first base plate 11 is open to form a side groove 13 that communicates with the slot 12. A deformable limiting head 14 is disposed inside the side groove 13. A limiting hole 110 is recessed on the plug 19 and matches the limiting head 14.

[0025] With the above technical solution, before the user uses the device, the first base plate 11 is fixed to the washing machine, the switch 2 is fixed to the washing machine, and the plug 19 is inserted into the slot 12 on the first base plate 11. After the plug 19 is inserted into the slot 12, the limiting head 14 engages with the limiting hole 110 on the plug 19 to fix the plug 19, thereby completing the installation of the elastic piece 111. When the user uses the device, the elastic piece 111 cooperates with the switch 2 to trigger the switch 2 or stop the switch 2 from working. When the user needs to remove the elastic piece 111 for replacement, the limiting head 14 in the side groove 13 is pulled to separate the limiting head 14 from the limiting hole 110 on the plug 19, thereby pulling the elastic piece 111 and moving the plug 19, thereby separating the plug 19 from the slot 12, and the elastic piece 111 and the plug 19 can be removed for replacement.

[0026] Specifically, in one embodiment, regarding the aforementioned switch element 2, as... Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the switch component 2 includes a pre-fixed second base plate 24. One side of the second base plate 24 is open to form a connecting groove 25, and the top and bottom of the second base plate 24 are recessed to form L-shaped slots 26. The L-shaped slots 26 communicate with the connecting groove 25, and a pluggable safety switch body 21 is provided inside the connecting groove 25. The top and bottom of the safety switch body 21 are fixedly connected with a lever 23 that matches the L-shaped slot 26.

[0027] In this embodiment, when personnel need to fix the switch 2, the second base plate 24 is fixed to the washing machine, and then the safety switch body 21 is engaged with the connecting groove 25 on one side of the second base plate 24. The locking rod 23 on the safety switch body 21 is engaged with the L-shaped locking groove 26 on the second base plate 24. The safety switch body 21 is pushed to the bottom and then pushed horizontally so that the safety switch body 21 is fully engaged inside the L-shaped locking groove 26. The safety switch body 21 is triggered or stopped by the cooperation of the elastic piece 111.

[0028] After the safety switch body 21 is installed, in order to improve the stability of the safety switch body 21 during installation, such as Figures 5-6 As shown, two mounting cavities 27 are symmetrically formed inside the second substrate 24. The connecting groove 25 is located between the two mounting cavities 27, and the mounting cavity 27 is connected to the L-shaped slot 26. A spring 29 is fixedly connected inside the mounting cavity 27. A limit rod 28 is fixedly connected to the free end of the spring 29. The free end of the limit rod 28 extends into the L-shaped slot 26.

[0029] In this embodiment, after the locking rod 23 is fully engaged inside the L-shaped slot 26, the spring 29 is supported by the mounting cavity 27, and the limiting rod 28 is supported by the spring 29. This allows one end of the limiting rod 28 to be inside the L-shaped slot 26, and the limiting rod 28 blocks the locking rod 23, thereby making the safety switch body 21 more stable after installation, preventing the safety switch body 21 from accidentally falling off after installation, and improving the stability of the safety switch body 21 during use after installation.

[0030] Furthermore, regarding how the second substrate 24 is fixed in this invention, as follows: Figures 5-6As shown, the top and bottom of the second substrate 24 are fixedly connected to the second side plate 210. The second side plate 210 is screwed onto the second screw 211. When personnel need to fix the second substrate 24, the second substrate 24 is placed at the position to be fixed, and then the second screw 211 is inserted into the second side plate 210. The second screw 211 is rotated to move relative to the second side plate 210 until the second screw 211 enters into another object, thereby fixing the second side plate 210 and the second substrate 24.

[0031] And when personnel need to pull the limit head 14, in order to make the limit head 14 easy to pull, such as Figures 1-4 As shown, the side of the limiting head 14 away from the slot 12 is recessed to form a groove 15.

[0032] In this embodiment, when a person pulls the limiting head 14, the pulling groove 15 makes it easy to pull the limiting head 14.

[0033] Furthermore, regarding how the first substrate 11 is fixed in this utility model, as follows: Figures 1-4 As shown, the top and bottom of the first substrate 11 are fixedly connected to the first side plate 16, and the first side plate 16 is screwed onto the first screw 17.

[0034] In this embodiment, when personnel need to fix the first substrate 11, the first substrate 11 is placed at the position to be fixed, and then the first screw 17 is inserted into the first side plate 16 and rotated until the first screw 17 enters into another object. The first screw 17 abuts against the first side plate 16, thereby fixing the first substrate 11.

[0035] When the first substrate 11 and the second substrate 24 are fixed, in order to improve the stability of the first substrate 11 and the second substrate 24 after fixing, such as Figures 1-6 As shown, a first rubber plate 18 is bonded to the side of the first substrate 11 away from the limiting head 14, and a second rubber plate 22 is bonded to the side of the second substrate 24 away from the safety switch body 21.

[0036] In this embodiment, when personnel fix the first substrate 11 and the second substrate 24, the first rubber plate 18 and the second rubber plate 22 cooperate to make the first substrate 11 and the second substrate 24 more secure after fixing.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
