[0031] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the utility model. These all fall within the scope of protection of the utility model.
[0032] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Example
[0033] See also Figure 1-4The utility model discloses a thin keyboard switch, comprising a base 10, a spring 20, a handle 30, a contact sheet 40, a terminal 50 and an upper cover 60, wherein the upper cover 60 is provided with a guide boss 11 extending in the direction of the base 10, the handle 30 is slidably connected with the guide boss 11, and the guide boss 11 is arranged along the circumference of the handle; in the present embodiment, the handle 30 is cylindrical in shape, and four extending parts opposite to each other are symmetrically arranged on both sides of the cylindrical body, and a connecting part integrally formed with the lower part of the cylindrical body is arranged between the bottoms of two adjacent extending parts on the same side of the cylindrical body, and the inner wall surface of the guide boss 11 is provided with eight first circular convex ribs 111 arranged in the vertical direction, each extending A first circular convex rib 111 is respectively provided on one side of the extension portion relative to the cylindrical main body and on one side of the adjacent extension portion relative to the same side of the cylindrical main body, and the eight first circular convex ribs 111 are in contact with the outer wall surface of the push handle 30; the linear outer wall surface of the eight first circular convex ribs 111 is in contact with the outer wall surface of the push handle 30, which can not only position the up and down movement of the push handle 30 to prevent it from shaking, but also make the up and down movement of the push handle 30 smoother; when the shape of the push handle 30 changes, the shape of the guide boss 11 and the position of the first circular convex rib 11 thereon also need to change accordingly, so that the guide boss 11 can limit the push handle 30 while ensuring its smoothness.
[0034] A guide column 12 is provided on the base 10, and a cylinder 31 is extended from the handle 30 toward the base 10. A guide blind hole 311 is opened on the cylinder 31. The guide column 12 cooperates with the guide blind hole 311 and can move up and down along the guide blind hole 311. The outer wall surface of the guide column 12 is provided with four second circular convex ribs 121 arranged in a vertical direction, which are arranged in a cross. The second circular convex ribs 121 are in contact with the inner wall surface of the guide blind hole 311. By arranging the second circular convex ribs 121 on the guide column 12 on the base 10 to cooperate with the guide blind hole 311 on the handle 30, the up and down movement of the handle 30 is further limited, and the smoothness of its up and down movement is further improved.
[0035] The depth of the guide blind hole 311 is from the bottom of the button handle to the top of the button handle, and the length of the guide column 12 is adapted to the depth of the guide blind hole 311. Since the depth of the guide blind hole 311 basically runs through the entire button handle 30, the button handle 30 has a longer stroke, and the entire up and down movement can be restricted by the guide boss 11, which can further reduce the shaking of the button handle 30 and ensure that the up and down displacement of the button handle 30 is smooth and reliable.
[0036] In this embodiment, two elastic buckles 13 are symmetrically disposed on both sides of the base 10, so that the utility model can be easily removed from the keyboard panel.
[0037] In this embodiment, a sound-generating spring piece 70 is disposed on one side of the push handle 30 relative to the terminal 50. The sound-generating spring piece 70 is embedded in the base 10. The contact portion 71 of the sound-generating spring piece 70 is in dynamic contact with the push handle 30. Through the arrangement of the sound-generating spring piece 70, the push handle 30 is in contact with it when moving up and down, and provides a certain sound and sense of paragraph.
[0038] In this embodiment, the contact piece 40 and the two pins of the terminal 20 extending out of the base are arranged in parallel, and can be compatible with conventional plug sockets in the current market, making it convenient for users to replace the utility model.
[0039] In this embodiment, the handle 30 extends toward the contact piece 40 with a protrusion 32, and the cross-section of the protrusion 32 is arc-shaped. The protrusion 32 is in dynamic contact with the contact piece 40. When the shape of the protrusion 32 is set to different shapes, when it cooperates with the contact piece 40, different tactile effects can be achieved.
[0040] In summary, the present invention solves the deficiencies in the prior art through the above-mentioned structural design, and has the characteristics of reasonable design, stability, reliability, and smooth displacement.
[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
