Description

Switch assembly with limit function

The invention relates to a switch assembly with a limit function.

Press, the general switch assembly has a rotating shaft, and the opening and closing of the switch assembly can be controlled by the rotation of the rotating shaft. Since the rotating shaft needs a strong rotating force to rotate smoothly, a lever is set on the rotating shaft to have The rotating shaft is rotated with a relatively large torque, and in order to effectively limit the rotation range of the rotating shaft, a locking projection is provided on the shift lever, so that the locking projection will be limited by the stop edge of the switch assembly when the shift lever rotates. However, after the conventional shift lever is used for a period of time, under the condition of long-term stress, it is easy to cause structural fatigue and fracture. Therefore, the shift lever needs to be replaced frequently, and there are shortcomings that need to be improved.

Therefore, it is necessary to provide a novel and advanced switch assembly with limit function to solve the above-mentioned problems.

The main purpose of the present invention is to provide a switch assembly with a limit function, which can avoid fatigue and fracture of the lower clip structure after long-term use, so it has strong durability and simple structure.

To achieve the above objective, the present invention provides a switch assembly with a limit function, which includes a body and a driving structure. The main body is provided with a rotating shaft that rotates along an axial direction. The driving structure is simultaneously arranged on the rotating shaft and includes a limiting portion and a handle. One of the main body and the limiting portion is provided with at least one clamping member, and the other is provided with at least one slot, the at least A clip is made of metal, the handle is made of non-conductive material, the clip is limited to the notch to limit the rotation range of the shaft, and the shaft is driven by pulling the handle to selectively open and close the shaft Ontology.

The following examples are only used to illustrate the possible implementation aspects of the present invention, but they are not intended to limit the scope of protection of the present invention, and are described first.

Please refer to FIGS. 1 to 7, which show a preferred embodiment of the present invention. The switch assembly with limit function of the present invention includes a body 1 and a driving structure 2.

The main body 1 is provided with a rotating shaft 12 that rotates along an axial direction 11.

The driving structure 2 is simultaneously arranged on the rotating shaft 12 and includes a limiting portion 3 and a handle 4. One of the body 1 and the limiting portion 3 is provided with at least one clamping member 31, and the other is provided with At least one notch 13, the at least one clip 31 is made of metal, the handle 4 is made of non-conductive material, the clip 31 is limited to the notch 13 to limit the rotation range of the shaft 12, by pulling the handle The part 4 drives the rotating shaft 12 to selectively open and close the main body 1. In this embodiment, the handle 4 is a plastic part, and the limiting part 3 and the main body 1 are metal parts. Therefore, since the at least one clamping part 31 is made of metal, it has a strong structural strength to avoid The at least one clamping member 31 is fatigued and broken when the at least one notch 13 is engaged for a long time, so it can have strong durability, and the handle 4 is a plastic part, which can have a low manufacturing cost. Cost and enhance the user's comfort when holding, in addition, it can avoid the user's electric shock hazard when the main body is conductive.

Specifically, in this embodiment, the at least one clamping element 31 is integrally formed on the limiting portion 3 and is bent toward the at least one notch 13 along the axial direction 11. In other embodiments, the at least one clamping element is provided It is also indispensable for the body and the at least one missing slot to be provided on the limiting portion. In addition, in this embodiment, the main body 1 is provided with two notches 13, and the limiting portion 3 is provided with two clips 31. The two notches 13 are respectively located on opposite sides of the rotating shaft 12 along the axial direction 11. It can be seen that the two grooves 13 are in a concave shape, and the rotation range of the limiting portion 3 is the range in which the clamping member 31 moves at the two ends of the groove 13.

Preferably, the limiting portion 3 is provided with a non-circular perforation 32, the rotating shaft 12 is a non-circular cylinder, and the perforating 32 of the limiting portion 3 is sleeved on the rotating shaft 12 so that the limiting portion 3 It rotates in conjunction with the rotating shaft 12. In this embodiment, the main body 1 is provided with a flat surface 14, the limiting portion 3 is plate-shaped, the limiting portion 3 abuts against the flat surface 14, and the two grooves 13 are recessed in the flat surface 14.

Furthermore, the handle 4 is provided with a groove 41 having a shape corresponding to the rotating shaft 12, and the groove 41 is sleeved on the rotating shaft 12, so that the handle 4 and the rotating shaft 12 rotate in conjunction with each other, and the limiting portion 3 It is sandwiched between the handle 4 and the main body 1 to prevent the limiting portion 3 from moving axially 11 relative to the rotating shaft 12.

Preferably, one end of the rotating shaft 12 away from the main body 1 is provided with a first locking hole 121, the handle 4 is penetrated with a second locking hole 42 communicating with the groove 41, and the handle of a locking member 5 The side of the portion 4 away from the main body 1 passes through the second locking hole 42 and is fixed to the first locking hole 121 to fix the handle 4 to the rotating shaft 12. In this embodiment, one end of the rotating shaft 12 away from the main body 1 is recessed with a long groove 122, and the bottom of the groove 41 is provided with a convex portion 43 protruding toward the rotating shaft 12, and the convex portion 43 is inserted into the long groove 122 to This further prevents the handle 4 from rotating relative to the rotating shaft 12.

In addition, the handle 4 includes a sleeve 44 and a handle 45 integrally formed. The sleeve 44 is cylindrical, the groove 41 is recessed in the sleeve 44, and the handle 45 extends radially from the sleeve 44. The outer peripheral wall is used to increase the torque when the handle 4 is pulled. The handle 45 is provided with a hollow portion 451 toward one end of the main body 1 to reduce the material and weight of the handle 45. The shaft 12 is far away from one end of the main body 1 A chamfer 123 is respectively provided on both sides along the extending direction of the long groove 122 to prevent the shaft 12 and the groove 41 from being worn away. The connection between the clamping member 31 and the limiting portion 3 is radially concave with two concaves The arc 33 makes it easier to bend the clamping member 31, and the shaft 12 is in the shape of a rectangular column, and in other embodiments may also be in the shape of a polygonal column with other shapes.

In summary, the switch assembly with limit function of the present invention, because the at least one clip 31 is made of metal, can have a strong structural strength to prevent the at least one clip 31 from interacting with the at least one slot 13 for a long time. In the case of jamming, the structure is fatigued and broken, so it can have strong durability, and the handle 4 is a plastic part, which can have lower manufacturing costs and improve the comfort of the user when holding it, and it can also avoid When the body is conductive, the user will be exposed to electric shock.
