In order to improve the installation stability of each shaft switch, the mechanical keyboard also includes a positioning plate with a shaft switch socket. The positioning plate is a flat plate and is arranged above the circuit board. The shaft switch passes through the shaft switch socket of the positioning plate from top to bottom and then is connected to the circuit board.

[0003] The existing mechanical keyboards with positioning plates have the following problems in the process of installing the positioning plates: when the positioning plates are installed on the circuit boards, they are usually positioned manually and then welded or fasteners are installed. This positioning method is prone to positioning deviations, resulting in displacement of the positioning plates. At the same time, this positioning method consumes more energy and has a low positioning efficiency.

[0004] Based on this, the applicant considered designing a keyboard positioning plate installation device that can accurately position. Utility Model Content

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A keyboard positioning plate installation device that can be accurately positioned includes a carrier plate, a fixed clamping portion and a movable clamping portion. The carrier plate is rectangular, and one end of the carrier plate in the length direction is a fixed end, and the other end is a movable end. The fixed clamping portion is installed on the fixed end of the carrier plate, and the movable clamping portion is installed on the movable end of the carrier plate. The movable clamping portion can slide elastically along the length direction of the carrier plate, and is used to apply an elastic clamping force in the direction of the fixed clamping portion.

[0008] Compared with the prior art, the keyboard positioning plate installation device of the utility model which can accurately position has the following advantages:

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] When implementing: Figure 1 As shown, a keyboard positioning plate installation device that can be accurately positioned includes a carrier plate 100, a fixed clamping portion 200 and a movable clamping portion 300. The carrier plate 100 is rectangular, and one end of the carrier plate 100 is a fixed end, and the other end is a movable end in the length direction of the carrier plate 100. The fixed clamping portion 200 is installed on the fixed end of the carrier plate 100, and the movable clamping portion 300 is installed on the movable end of the carrier plate 100. The movable clamping portion 300 can slide elastically along the length direction of the carrier plate 100, and is used to apply an elastic clamping force toward the fixed clamping portion 200.

[0023] The advantages are: elastic pressure can be applied to the fixed clamping part 200 through the movable clamping part 300, so that the positioning plate is positioned on the circuit board. This method is accurate in positioning and is not likely to cause displacement of the positioning plate. At the same time, this positioning method is mechanical positioning, which consumes less energy during positioning and has high positioning efficiency. The structure is simple, easy to implement, and suitable for use in the existing keyboard positioning plate positioning installation.

[0024] In this embodiment, Figure 1 As shown, the fixed clamping portion 200 includes a first clamping arm 210 and a second clamping arm 220. The first clamping arm 210 is fixedly connected to the upper portion of the fixed end of the carrier 100, and the second clamping arm 220 is fixedly connected to the lower portion of the fixed end of the carrier 100. The first clamping arm 210 and the second clamping arm 220 are arranged opposite to each other in the width direction of the carrier 100.

[0025] In this way, the keyboard positioning plate is in a rectangular shape, and the fixed clamping portion 200 has two clamping arms, which can clamp the two ends of the wide side of the keyboard positioning plate, thereby improving the positioning effect of the keyboard positioning plate in the length direction and making the positioning more accurate.

[0026] In this embodiment, Figure 1 As shown, the movable clamping portion 300 includes a third clamping arm 310 and a fourth clamping arm 320. The third clamping arm 310 is slidably connected to the upper part of the movable end of the carrier 100 along the length direction of the carrier 100, and the fourth clamping arm 320 is slidably connected to the lower part of the movable end of the carrier 100 along the length direction of the carrier 100. The third clamping arm 310 and the fourth clamping arm 320 are relatively arranged in the width direction of the carrier 100.

[0027] In this way, since the shape of the keyboard positioning plate is rectangular and the movable clamping part 300 has two clamping arms, the movable clamping part 300 can clamp the wide side of the other end of the keyboard positioning plate. The fixed clamping part 200 and the movable clamping part 300 also have two clamping arms, which makes the keyboard positioning plate more securely positioned, and the keyboard positioning plate and the circuit board can be more conveniently welded or locked.

[0028] In this embodiment, Figure 1 As shown, the first clamping arm 210 and the third clamping arm 310 are disposed opposite to each other in the length direction of the carrier 100 , and the second clamping arm 220 and the fourth clamping arm 320 are disposed opposite to each other in the length direction of the carrier 100 .

[0029] In this way, the first clamping arm 210 and the third clamping arm 310 are arranged opposite to each other in the length direction of the carrier plate 100 to enhance the positioning effect of the keyboard positioning plate in the width direction, and the positioning is more accurate.

[0030] Among them, Figure 1As shown, the first clamping arm 210 , the second clamping arm 220 , the third clamping arm 310 and the fourth clamping arm 320 are all right-angle clamping arms, and the right-angle openings are all facing the carrier 100 .

[0031] When implementing, Figure 4 As shown, the heights of the first clamping arm 210 , the second clamping arm 220 , the third clamping arm 310 and the fourth clamping arm 320 are all at least one centimeter higher than the supporting surface of the carrier board 100 .

[0032] In this way, the right-angle clamp arm can position the long side and the wide side of the keyboard positioning plate at the same time, and the positioning direction is more comprehensive.

[0033] In this embodiment, Figure 2 and Figure 3 As shown, the movable clamping part 300 also includes a first telescopic rod 330 and a second telescopic rod 340; the first telescopic rod 330 is installed on the upper part of the movable end of the carrier plate 100, and the telescopic end of the first telescopic rod 330 is fixedly connected to the third clamping arm 310, and a tension spring is sleeved on the first telescopic rod 330 for applying tension to the third clamping arm 310; the second telescopic rod 340 is installed on the lower part of the movable end of the carrier plate 100, and the telescopic end of the second telescopic rod 340 is fixedly connected to the fourth clamping arm 320, and a tension spring is sleeved on the second telescopic rod 340 for applying tension to the fourth clamping arm 320.

[0034] When implementing, Figure 2 As shown, the first telescopic rod 330 and the second telescopic rod 340 are arranged along the length direction of the carrier 100 and can be extended toward the movable end of the carrier 100. The initial positions of the telescopic ends of the first telescopic rod 330 and the second telescopic rod 340 are in the shortest telescopic state under the tension of the tension spring.

[0035] In this way, the first telescopic rod 330 and the second telescopic rod 340 can respectively enhance the sliding stability of the third clamping arm 310 and the fourth clamping arm 320 , so that the third clamping arm 310 and the fourth clamping arm 320 can slide more smoothly during the extension and contraction process.

[0036] In this embodiment, Figure 2 and Figure 3 As shown, a first slide rail 110 is provided in the upper part of the movable end of the carrier plate 100 , and the first telescopic rod 330 is installed in the first slide rail 110 ; a second slide rail 120 is provided in the lower part of the movable end of the carrier plate 100 , and the second telescopic rod 340 is installed in the second slide rail 120 .

[0037] During implementation, the sliding directions of the first slide rail 110 and the second slide rail 120 are consistent with the length direction of the carrier 100 .

[0038] In this way, the first slide rail 110 and the second slide rail 120 can respectively prevent the first telescopic rod 330 and the second telescopic rod 340 from being exposed outside the carrier 100, thereby reducing the occupied space outside the carrier 100 and better protecting the first telescopic rod 330 and the second telescopic rod 340.

[0039] In this embodiment, Figure 1 and Figure 6 As shown, the carrier board 100 has scale lines 130 , and the scale lines 130 are arranged on the long edge of the upper part of the carrier board 100 .

[0040] In this way, if Figure 6 As shown, the scale line 130 can intuitively display the length of the circuit board and the positioning plate to confirm the length of keyboard positioning plates of different specifications.

[0041] In this embodiment, Figure 5 As shown, a slope 140 is disposed at the bottom of the carrier 100 for tilting the carrying surface of the carrier 100 .

[0042] During implementation, the carrying surface of the carrying plate 100 faces the operator.

[0043] In this way, the inclined platform 140 makes the carrying surface of the carrier plate 100 tilt toward the operator, which is convenient for the operator to install and position the positioning plate on the carrier plate 100, so that the operator can also perform the positioning operation in a sitting state.

[0044] The usage process of this embodiment:

[0045] In the first step, the circuit board is installed between the fixed clamping part 200 and the movable clamping part 300. During installation, the two corners of the wide side of one end of the circuit board are respectively abutted against the third clamping arm 310 and the fourth clamping arm 320. Then, the third clamping arm 310 and the fourth clamping arm 320 slide to push the circuit board toward the movable end of the carrier board 100 along the length direction of the carrier board 100, so that the two corners of the wide side of the other end of the circuit board are respectively placed in the first clamping arm 210 and the second clamping arm 220.

[0046] The second step is, Figure 6 As shown, the keyboard positioning plate is stacked on the circuit board, so that the first clamping arm 210, the second clamping arm 220, the third clamping arm 310 and the fourth clamping arm 320 simultaneously position and clamp the circuit board and the keyboard positioning plate.

[0047] The third step is to weld or lock the clamped circuit board and keyboard positioning plate.

[0048] When the second step is performed, the length of the keyboard positioning plate can be measured by the scale line 130 on the carrier plate 100 .

[0049] The above are only preferred implementations of the present invention. It should be pointed out that a number of modifications and improved technical solutions made by those skilled in the art without departing from the present technical solution should also be deemed to fall within the scope of protection required by the claims.
