Description

Technical Field

[0001] The present application relates to the field of furniture switch structures, and in particular to a key structure for a toggle switch. Background Art

[0002] Some electric furniture requires a hand controller to adjust the posture of the furniture. The use of the hand controller is generally to operate the corresponding buttons to connect the switch to the corresponding circuit. The more common method is to move the buttons in opposite directions on a straight line to drive the switch handle of the toggle switch to different positions to achieve different adjustments of the furniture.

[0003] The existing buttons are generally tightly mounted on the switch handle of the toggle switch, and rely on the spherical surface on the switch handle to interfere with the button, for example, the electric furniture adjustment switch with the announcement number CN206834125U.

[0004] In the above-mentioned related technologies, when the key is toggled for a long time, the spherical surface of the key and the switch handle is prone to looseness, so that the key is easy to fall off the switch handle of the toggle switch, and the key cannot effectively drive the switch handle to move. Utility Model Content

[0005] In order to enable the key to effectively drive the switch handle to move during long-term use, the present application provides a key structure for a toggle switch.

[0006] The present application provides a key structure for a toggle switch that adopts the following technical solution.

[0007] A key structure for a toggle switch comprises a key body which is toggled to drive a switch handle to move, the key body being sleeved with a movable part, the movable part passing through and slidably connected to an upper cover with a fixed position, the movable part being slidably connected to a surface of the upper cover facing away from the key body, the movable part being tightly sleeved on the switch handle, and the movable part being fixedly connected to a gear point block which can be embedded in the key body.

[0008] By adopting the above technical solution, the key body is connected to the movable part through the stop block and is not easy to separate. The movable part is restricted by the upper cover and is not easy to separate from the switch handle. Therefore, the switch handle can be continuously and effectively moved during the long-term movement of the key body.

[0009] Optionally, the upper cover is detachably connected to a fixing plate, and a surface of the movable part facing away from the key body abuts against the fixing plate.

[0010] By adopting the above technical solution, the fixed plate can provide support force for the movable part, so that when the movable part is under pressure, it is not easy to directly transfer a large pressure to the switch handle, so that the corresponding toggle switch is not easily damaged.

[0011] Optionally, the movable part includes an upper column inserted into the key body and provided with a stop point block, a lower plate fixedly connected to the upper column, and a protrusion fixedly connected to the lower plate, and the protrusion is slidably connected to the surface of the upper cover away from the key body.

[0012] By adopting the above technical solution, the convex points can reduce the contact area between the lower plate and the upper cover, making the movement of the lower plate smoother.

[0013] Optionally, the number of the protrusions is at least three, and all the protrusions are not collinear.

[0014] By adopting the above technical solution, the lower plate can move stably along the surface of the upper cover.

[0015] Optionally, the upper column is slidably connected to the upper cover on two relative side surfaces along the moving direction of the switch handle.

[0016] By adopting the above technical solution, the upper column can move stably along the moving direction of the switch handle.

[0017] Optionally, the upper cover is fixedly connected to the limiting wall, and any one of the two end surfaces of the lower plate located in the moving direction of the switch handle can abut against the limiting wall.

[0018] By adopting the above technical solution, when the switch handle moves to the limit distance value, the lower plate will abut against the limit wall, so that the switch handle can no longer move, and the switch handle is not easily subjected to excessive external force.

[0019] Optionally, the upper column is provided with limiting openings on two opposite sides, and any one of the inner walls on the two sides adjacent to the limiting openings can abut against the inner wall of the opening of the upper cover for the upper column to pass through.

[0020] By adopting the above technical solution, when the switch handle moves to the limit distance value, the inner wall of the limit opening will abut against the limit wall, so that the switch handle can no longer move, making it difficult for the switch handle to withstand excessive external force.

[0021] Optionally, the shift point block is formed with a block slope, and the opening of the key body for the movable part to be inserted into can abut against the block slope to force the key body to deform.

[0022] By adopting the above technical solution, the key body is directly mounted and pressed against the movable part, so that a stable connection between the key body and the movable part can be achieved.

[0023] Optionally, the movable member is provided with stop blocks on two opposite sides, and the connection direction between the two stop blocks is perpendicular to the moving direction of the switch handle.

[0024] By adopting the above technical solution, the surface of the key body where the shift point block is embedded is not easily deformed due to the external force exerted on the key body by long-term manipulation, so that the shift point block can be effectively embedded in the key body and is not easy to fall off.

[0025] Optionally, two opposite side surfaces of the key body are fixedly connected with reinforcement strips, the reinforcement strips abut against the movable part, and the surface of the movable part abutting against the reinforcement strip is adjacent to the surface of the movable part where the stop point block is set.

[0026] By adopting the above technical solution, the surface of the key body perpendicular to its own moving direction is not easily deformed and damaged due to long-term impact force.

[0027] In summary, the present application includes at least one of the following beneficial effects:

[0028] When the key body is pushed for a long time, the switch handle can be pushed continuously and effectively, and the key body is not easy to fall off. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The present application is further described in detail below in conjunction with the accompanying drawings.

[0035] The present application embodiment discloses a key structure for a toggle switch, referring to Figure 1 and Figure 2 , including an upper cover 31 for the switch handle 1 to pass through, and the upper cover 31 is detachably connected to a housing for installing the toggle switch so that the position of the upper cover 31 remains fixed.

[0036] Reference Figure 2 and Figure 3The switch handle 1 is equipped with a movable part 3, and the movable part 3 includes an upper column 34 tightly sleeved on the switch handle 1 and penetrated through the upper cover 31. The upper column 34 is tightly plugged with a key body 2 for the user to directly dial. The upper column 34 is slidably connected to the upper cover 31 on two sides parallel to the moving direction of the switch handle 1. The upper column 34 is perpendicular to the moving direction of the switch handle 1. Both sides have limited openings 21. When the switch handle 1 moves to a limit distance in one direction, the inner wall of the limit opening 21 just abuts against the inner wall of the opening of the upper cover 31 for the upper column 34 to penetrate, so that when the user reaches the distance limit value in the process of dialing the key body 2, it is not easy for the switch handle 1 to be subjected to excessive pressure. The end of the upper column 34 away from the key body 2 is fixedly connected to the lower plate 35, and the surface of the lower plate 35 facing the upper cover 31 is fixedly connected to a protrusion 36. The protrusion 36 is a hemispherical point and makes point contact with the surface of the upper cover 31 away from the key body 2. The number of the protrusions 36 is at least three that are not colinear. In this embodiment, a protrusion 36 is set at each of the four corners of the lower plate 35.

[0037] Reference Figure 2 and Figure 3 The surface of the upper cover 31 away from the key body 2 is fixedly connected to the limiting wall 37. In this embodiment, the limiting wall 37 encloses a shape that is approximately a rectangular frame. The lower plate 35 is located in the space enclosed by the limiting wall 37. When the user reaches the distance limit value in the process of toggling the key body 2, the lower plate 35 can abut against the corresponding limiting wall 37, so that the switch handle 1 will not continue to move even if the key body 2 continues to be pressed. At the same time, the upper cover 31 is detachably connected to the fixing plate 33 by screws. The fixing plate 33 abuts against the surface of the lower plate 35 away from the upper column 34 to provide support for the movable part 3.

[0038] Reference Figure 3 and Figure 4 , the two opposite sides of the upper column 34 are fixedly connected with the stop point blocks 32, and the stop point blocks 32 can be embedded in the corresponding openings in the key body 2, so that the key body 2 and the upper column 34 are not easily separated. The two stop point blocks 32 are formed with block slopes 38 on the opposite sides, and the opening of the key body 2 for the upper column 34 to be inserted can abut against the block slopes 38, so that the key body 2 can be directly pressed against the upper column 34, so that the stop point blocks 32 can be smoothly embedded in the corresponding position inside the key body 2. The surface of the upper column 34 where the stop point blocks 32 are set is parallel to the moving direction of the switch handle 1, so that in the process of toggling the key body 2, the surface of the key body 2 where the stop point blocks 32 are embedded is not easy to withstand excessive pressure and thus is not easy to deform, so that the stop point blocks 32 can be effectively embedded in the key body 2. Reinforcement strips 39 are fixedly connected to the two opposite side surfaces inside the key body 2, and the upper column 34 abuts against the surface of the reinforcement strip 39 perpendicular to the moving direction of the switch handle 1, so that when the key body 2 is subjected to a large external force during the movement process, the reinforcement strip 39 can increase the strength of the corresponding inner wall of the key body 2 and is not easily deformed.

[0039] The implementation principle of the key structure for a toggle switch in the embodiment of the present application is: the key body 2 is toggled, so that the upper column 34 and the lower plate 35 move correspondingly, thereby driving the switch handle 1 to move correspondingly. Moreover, during the long-term toggle of the key body 2, the key body 2 and the upper column 34 are not easily separated due to the presence of the stop block 32, and the upper column 34 and the switch handle 1 are not easily separated due to the presence of the lower plate 35, so that the key body 2 can effectively drive the switch handle 1 to move during long-term use.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
