DETAILED DESCRIPTION

[0022] 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.

[0023] like Figure 1-7 As shown, a keyboard switch with a ball bearing comprises a cover body 1 and a base 2, wherein a button 3, a spring 4 and a switch trigger mechanism 5 are arranged in an installation cavity formed by assembling the cover body 1 and the base 2, wherein the switch trigger mechanism 5 is a metal conductive trigger structure composed of a contact piece and a terminal, wherein an opening for the button 3 to move is arranged on the cover body 1, and the switch trigger mechanism 5 is turned on and off by pressing the button 3, wherein a first guide structure 6 cooperating with the button 3 is arranged in the cover body 1, and a second guide structure 61 cooperating with the button 3 is arranged in the base 2, wherein a ball bearing 31 is arranged on an outer wall of the button 3, and both guide structures have a guide channel 62 forming a rolling cooperation with the ball bearing 31, and the button 3 is an independently formed integral part, wherein a positioning hole 7 and a positioning block 8 for accommodating the ball bearing 31 are formed on the button 3, wherein the positioning hole 7 matches the shape of the ball bearing 31, and a portion of the ball bearing 31 protrudes from the positioning hole 7. The button 3 is provided with a protrusion 71 at the position of the positioning hole 7, and the protrusion 71 is adapted to the first guide structure 6; the positioning block 8 is provided to protrude from the side surface of the button 3, and the positioning block 8 is adapted to the second guide structure 61; a limiting hole 81 and a limiting channel 82 located on both sides of the limiting hole 81 and connected to the limiting hole 81 are formed on the positioning block 8, the limiting hole 81 is adapted to the shape of the ball 31, and the ball 31 partially protrudes from the limiting hole 81; a pressing rod 32 is integrally formed below the button 3, the spring 4 is sleeved on the pressing rod 32, an active groove 21 that slides with the pressing rod 32 is provided in the base 2, and the ball 31 that rolls with the pressing rod 32 is also provided in the active groove 21; a cover plate 9 is provided above the active groove 21 in the base 2, and the cover plate 9 includes an insertion portion 91 for inserting the pressing rod 32.

[0024] By adopting the above technical solution, in the utility model, compared with the prior art, the main improvement is that the button 3 is independently manufactured and formed, and a positioning hole 7 and a positioning block 8 for installing the ball are set on the button 3, wherein the ball 31 in the positioning hole 7 rolls with the guide channel 62 on the first guide structure 6; the ball 31 in the positioning block 8 rolls with the guide channel 62 on the second guide structure 61, so that the button 3 can reduce friction when moving relative to the cover 1 and the base 2. Among them, the setting of the protrusion 71 can be adapted to the first guide structure 6, and when the ball 31 is installed in the positioning hole 7, the setting of the protrusion 71 can provide good installation positioning when the button 3 is assembled to the cover 1, and can achieve good clearance fit between the ball 31 and the guide channel 62. Similarly, the positioning block 8 is set to protrude from the side surface of the button 3, and also to achieve fit with the second guide structure 61, so that the button 3 can be assembled to the base 2 smoothly, and provide accurate installation clearance for the ball 31 to achieve rolling fit with the guide channel 62 of the second guide structure 61. Among them, the upper limit hole 81 of the positioning block 8 is mainly used to accommodate the positioning ball 31, and the setting of the limiting channels 82 on both sides can limit the lateral movement of the roller to prevent it from escaping from the limiting hole 81 when rolling. The diameter of the limiting channel 82 is smaller than the diameter of the limiting hole 81. In this way, based on the improved design of the utility model, during installation, the roller can be directly installed in the corresponding positioning hole 7 and the limiting hole 81, which is convenient for installation, and the setting of the protrusion 71 and the positioning block 8 provides more convenient and accurate assembly positioning. By independently manufacturing the button 3 in one piece, the structural strength of the button 3 is better, the service life is longer, and the production quality of the product is higher, and it is easier to assemble the ball 31.
