Description

Technical Field

[0001] The utility model relates to the field of mechanical keyboards, in particular to a computer keyboard key support which prevents key caps from loosening. Background Art

[0002] Nowadays, information circulates rapidly, and computers are indispensable tools in all industries. The types and styles of computers are also changing with each passing day as their functions increase day by day. Because laptops are easy to carry and can be used in a variety of occasions, they are gradually replacing desktop computers. Regardless of the style of computer, the interface for communicating with the user is still mainly keyboard, and a large number of brackets are used on the keyboard. The keys of existing computer keyboards generally adopt a scissor-foot key bracket structure, and the scissor-foot key bracket is usually hinged by a main bracket and a sub-bracket.

[0003] The utility model discloses a computer keyboard key bracket for preventing keycaps from loosening, which belongs to the technical field of keyboard keys and comprises a keycap, a key base plate, a scissor foot and an anti-slip component, wherein the scissor foot and the anti-slip component are both arranged between the keycap and the key base plate, and the anti-slip component is located on the outside of the scissor foot, and the anti-slip component comprises a support rod and a limit block, wherein the support rod is connected to the key base plate, the limit block is connected to the support rod, and the limit block is slidably connected to a slide groove provided in the keycap. The utility model can effectively solve the problem that the keycap is easily lifted or overturned when the key is subjected to collision or external force, resulting in the keycap falling off by the anti-slip component provided. However, when the bracket of this scheme is used for a long time, the ball as a key component of the computer keyboard is easily worn out after long-term use, which will have a significant impact on the use of the key, resulting in the problem that the key is insensitive or stuck. For this reason, we propose a computer keyboard key bracket for preventing the keycaps from loosening. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a computer keyboard key bracket which prevents key caps from loosening, thereby solving the above-mentioned problems.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a computer keyboard key support for preventing keycaps from loosening, comprising a keycap, a base provided at the lower end of the keycap, a connecting column installed at the upper end of the inner wall of the keycap, and a cross frame installed at the side end of the connecting column, and also comprising:

[0006] A spring is installed at the lower half of the connecting column, and a horizontal plate is provided at the bottom end of the connecting column;

[0007] The structure used to limit the range of movement of the cross plate includes at least one limit block.

[0008] Preferably, the transverse plate is located at the center of the spring, and the transverse plate protrudes from the surface of the spring.

[0009] Preferably, there are two limit blocks, and the distance between the two limit blocks gradually increases from top to bottom.

[0010] Preferably, a side plate is installed at the side end of the limit block, and the side plate connects the side ends of the two limit blocks.

[0011] Preferably, both ends of the transverse plate are rounded.

[0012] Preferably, the cross frame is installed above the limit block.

[0013] Compared with the prior art, the utility model provides a computer keyboard key bracket that prevents key caps from loosening, which has the following beneficial effects:

[0014] 1. The computer keyboard key bracket that prevents the keycap from loosening has a horizontal bar at the center of the spring, which can keep the spring normally compressed and the keycap moving normally. The two ends of the horizontal bar are rounded to reduce the friction between the horizontal bar and the limit block, and the use is longer.

[0015] 2. The computer keyboard key bracket for preventing the keycap from loosening has two limit blocks that are narrow at the top and wide at the bottom, so that the horizontal plate can be restricted inside the two limit blocks to prevent the keycap from being lifted up due to external force.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 A computer keyboard key bracket for preventing a keycap from loosening comprises a keycap 1, a base 2 is arranged at the lower end of the keycap 1, a connecting column 3 is installed at the upper end of the inner wall of the keycap 1, and a cross frame 8 is installed at the side end of the connecting column 3, and also comprises; a spring, a spring 6 is installed at the lower half of the connecting column 3, and a cross plate 7 is arranged at the bottom end of the connecting column 3; a structure for limiting the range of movement of the cross plate 7, including at least one limiter, and the general composition of the main body.

[0023] Furthermore, the transverse plate 7 is located at the center of the spring 6 and protrudes from the surface of the spring 6 . The transverse plate 7 is located at the center of the spring 6 , leaving room for compression and rebound of the spring 6 below, and the spring 6 fixes the position of the transverse plate.

[0024] Furthermore, there are two limit blocks, and the distance between the two limit blocks gradually widens from top to bottom. The distance above the limit block 4 is smaller than the cross plate 7, so that the cross plate 7 is separated from the upper end of the limit block 4.

[0025] Furthermore, a side plate 5 is installed at the side end of the limit block, and the side plate 5 connects the side ends of the two limit blocks to fix the side close to the outside.

[0026] Furthermore, both ends of the transverse plate 7 are in a rounded state to reduce the friction between the transverse plate and the limit block.

[0027] Furthermore, the cross frame 8 is installed above the limiting block 4 to support the keycap 1 .

[0028] Working principle: Press the keycap 1, the keycap 1 drives the cross frame 8 to descend, the keycap 1 and the connecting column 3 descend, the connecting column 3 drives the spring 6 below to compress, and the cross plate 7 at the lower end of the connecting column 3 moves downward within the range of the two limit blocks 4. Release the keycap 1, the spring 1 retracts, and drives the cross plate 7 back to its position. However, when subjected to external force, the cross plate 7 rises, and the distance between the two limit blocks 4 fixes the active position of the cross plate 7, effectively preventing the keycap 1 from being lifted up or overturned. The rounded corners on both sides of the cross plate 7 reduce the friction between the cross plate 7 and the limit blocks 4.

[0029] 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.
