The technical scheme that the utility model adopts to achieve the above-mentioned purpose is:

A waterproof balance shaft of a keyboard is characterized in that it comprises a base and a waterproof guide core arranged on the base, wherein a waterproof blocking wall is formed on the waterproof guide core and is surrounded on the base.

As a further improvement of the present invention, a waterproof groove is formed on the waterproof guide core inside the waterproof retaining wall.

As a further improvement of the present invention, a movable jack is formed on the base, and a wall is formed on the base and located at the periphery of the movable jack to be movably inserted into the waterproof groove; A plug-in shaft which is movably inserted into the movable jack is extended downward, and the waterproof groove ring is arranged on the upper periphery of the plug-in shaft, and is located between the waterproof retaining wall and the plug-in shaft.

As a further improvement of the present invention, a balance rod insertion hole is formed on one side of the waterproof guide core, and a guide slope is respectively formed on the upper inner wall and the lower inner wall of the balance rod insertion hole.

As a further improvement of the present invention, an upper clamping groove is formed on the upper end face of the waterproof guide core.

As a further improvement of the present invention, a panel slot and at least one balance bar slot are respectively formed on the side edges of the base.

The beneficial effects of the utility model are: the special structure design of the waterproof retaining wall on the waterproof guide core can block the opening on the base, can effectively prevent external moisture and dust from entering the keyboard from the base, and play the role of waterproof and dustproof. It reduces the impact on the performance of the keyboard and prolongs the service life of the keyboard. It is especially suitable for the long keys of the keyboard, and plays the role of balancing the keys and waterproofing.

The above is an overview of the technical solution of the utility model. The utility model will be further described below with reference to the accompanying drawings and specific embodiments.

Detailed ways

In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose, the specific implementation of the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.

Please refer to FIGS. 1 and 2 , an embodiment of the present invention provides a waterproof balance shaft 1 for a keyboard, which includes a base 11 and a waterproof guide core 12 disposed on the base 11 , wherein a waterproof guide core 12 is formed on the waterproof guide core 12 . There is a waterproof retaining wall 121 surrounding the base 11 . The setting of the waterproof retaining wall 121 blocks the opening on the base 11 , which can effectively prevent external moisture and dust from entering the keyboard from the base 11 , and play the role of waterproof and dustproof.

For the combination of the waterproof guide core 12 and the base 11 , in this embodiment, a waterproof groove 122 is formed on the waterproof guide core 12 inside the waterproof retaining wall 121 , as shown in FIGS. 1 and 4 .

At the same time, as shown in FIG. 3 , a movable socket 111 is formed on the base 11, and a wall 112 is formed on the base 11 and located at the periphery of the movable socket 111 to be movably inserted into the waterproof groove 122; The lower part of the waterproof guide core 12 extends downward and is provided with a plug-in shaft 123 that is movably inserted into the movable socket 111 . between. Therefore, by inserting the plug-in wall 112 on the base 11 into the waterproof groove 122, the waterproof retaining wall 121 is surrounded by the plug-in wall 112 on the base 11, thereby blocking the movable jack 111 on the base 11. , which can effectively prevent external moisture and dust from entering the keyboard from the movable jack 111 of the base 11, and play the role of waterproof and dustproof.

In this embodiment, as shown in FIG. 1 and FIG. 5 , a balance rod insertion hole 124 is formed on one side of the waterproof guide core 12 , and a guide slope is formed on the upper inner wall and the lower inner wall of the balance rod insertion hole 124 respectively. 1241. Correspondingly, a side socket 110 corresponding to the balance rod socket 124 is provided on the base 11 .

At the same time, as shown in FIG. 2 , an upper slot 125 is formed on the upper end surface of the waterproof guide core 12 , for inserting the positioning post on the keycap 5 .

Meanwhile, as shown in FIG. 3 , a panel slot 113 and at least one balance bar slot 114 are respectively formed on the side of the base 11 .

As shown in FIG. 5 , when the keyboard waterproof balance shaft 1 is integrally installed on the keyboard panel 3, the keyboard panel 3 is inserted into the panel slot 113 of the base 11, and at the same time, one end of the balance rod 2 is inserted into the side insert of the base 11 in turn.
