Abstract
Description
Technical Field
[0001] The utility model relates to a wall switch, in particular to a high-reliability wall switch. Background Art
[0002] At present, a wall switch refers to an electrical switch installed on a wall for use, which is used to connect and disconnect the circuit and control the switch of the lighting. The existing wall switch includes a base, a pressure cover, a push plate rotatably set on the base, a switch button rotatably set on the pressure cover and linked with the pressure plate, a moving contact bridge, a spring set between the switch button and the moving contact bridge, a static contact, and a wiring terminal. The switch button of the existing wall switch is engaged in the pressure cover through the positioning shafts on both sides. When the pressure plate is pressed, the two driving arms of the pressure plate drive the switch button to rotate. However, during long-term use, due to the eccentricity of the pressure plate or the switch button, the two driving arms of the pressure plate cannot reliably drive the switch button to rotate, the performance is unreliable, and even the wall switch fails and has a short service life. Summary of the invention
[0003] The purpose of the utility model is to overcome the defects of the prior art and provide a high-reliability wall switch with simple structure, stable and reliable performance, good hand feeling and long service life.
[0004] To achieve the above-mentioned purpose, the utility model adopts a high-reliability wall switch, including a base, a pressure cover, a switch button rotatably arranged in the pressure cover, a pressing plate rotatably arranged on the pressure cover and used to drive the switch button to perform opening and closing actions, a moving contact bridge linked with the switch button, a spring arranged between the moving contact bridge and the switch button, and a static contact matched with the moving contact bridge. Two driving arms are symmetrically arranged on the pressure cover, two sliding grooves matched with the two driving arms are arranged in the switch button, the two driving arms are respectively inserted in the two sliding grooves, and the two driving arms move with the pressure plate and reciprocate in the two sliding grooves respectively, and form a linkage cooperation between the switch button and the two driving arms, two convex strips matched with the pressure plate are provided at both ends of the switch button, and two pressing blocks matched with the two convex strips are provided on the pressure plate, the two pressing blocks move with the pressure plate and respectively abut against the convex strips, and form a linkage cooperation between the convex strips and the pressing blocks.
[0005] The beneficial effect of the above structure is that the push plate adopts a dual-drive structure design. When the push plate is pressed, if one of the drive structures fails to work properly due to an accident, the other drive structure can work normally. The push plate drives the switch button to rotate through the drive arm and the pressure block, thereby ensuring that the push plate can reliably drive the switch button to move, which is beneficial to improving the working reliability of the wall switch and extending the service life of the wall switch. Therefore, the wall switch has the advantages of simple structure, stable and reliable performance, good hand feel and long service life.
[0006] In particular, the tail of the driving arm has an arc-surface protrusion, which moves with the driving arm and slides back and forth in the sliding groove. The driving arm slides in the sliding groove through the arc-surface protrusion, which avoids the driving arm and the switch button from getting stuck, and ensures that the driving arm can reliably drive the switch button to move, which is beneficial to improving the working reliability of the wall switch.
[0007] In particular, two guide holes are respectively arranged on the gland corresponding to the two convex strips, the two convex strips are respectively inserted into the two guide holes, and the two convex strips move back and forth in the two guide holes along with the switch button. The guide holes guide the convex strips, which can prevent the switch button from deviating, thereby facilitating the reliability of the switch button operation.
[0008] In particular, reinforcing ribs are respectively arranged on one side of the two convex strips, which can enhance the overall strength of the convex strips, thereby improving the working reliability of the wall switch and prolonging its service life.
[0009] In particular, a plurality of reinforcing ribs are respectively arranged on one side of the two driving arms. The reinforcing ribs can enhance the overall strength of the driving arms, which is beneficial to improving the working reliability of the wall switch and prolonging its service life.
[0010] In particular, two limiting grooves cooperating with the pressing plate are arranged at both ends of the pressing cover, and limiting convex strips cooperating with the two limiting grooves are arranged in the pressing plate, and the limiting convex strips move with the pressing plate and are inserted in the limiting grooves. The pressing plate cooperates with the limiting grooves of the pressing cover through the limiting convex strips, and when the pressing plate is pressed, the pressing plate is not easy to deviate, thereby ensuring that the pressing plate can move reliably, which is conducive to improving the working reliability of the wall switch.
[0011] In particular, two supporting shafts cooperating with the pressing plate are arranged on both sides of the pressure cover, two clamping plates cooperating with the two supporting shafts are arranged inside the pressure plate, and the two clamping plates are respectively provided with clamping grooves, and the clamping grooves of the two clamping plates are clamped on the two supporting shafts, and constitute the rotational connection and cooperation between the two clamping plates and the two supporting shafts. The pressing plate is clamped on the two supporting shafts of the pressure cover through the two clamping plates, so as to facilitate the assembly of the pressing plate and the pressure cover, make the assembly more convenient, and ensure that the pressing plate can rotate reliably on the supporting shaft.
