Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose, the following detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings and preferred embodiments.

Referring to fig. 1 and 2, an embodiment of the present invention provides a keyboard waterproof balance shaft 1, including a base 11 and a waterproof guide core 12 disposed on the base 11, wherein a waterproof retaining wall 121 is formed on the waterproof guide core 12 and surrounds the base 11. By the setting of waterproof barricade 121, shelter from the opening on the base 11, can prevent effectively that outside moisture and dust from getting into the keyboard in the base 11, play waterproof dustproof effect.

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

Meanwhile, as shown in fig. 3, a movable insertion hole 111 is formed in the base 11, and an insertion wall 112 is formed on the base 11 and located at the periphery of the movable insertion hole 111 to be movably inserted into the waterproof groove 122; an inserting shaft 123 movably inserted into the movable inserting hole 111 is extended downwards at the lower part of the waterproof guide core 12, and the waterproof groove 122 is annularly arranged on the periphery of the upper part of the inserting shaft 123 and is positioned between the waterproof retaining wall 121 and the inserting shaft 123. Therefore, by inserting the insertion wall 112 on the base 11 into the waterproof groove 122, the waterproof retaining wall 121 surrounds the insertion wall 112 on the base 11, so as to shield the movable insertion hole 111 on the base 11, thereby effectively preventing external moisture and dust from entering the keyboard from the movable insertion hole 111 of the base 11, and playing a waterproof and dustproof role.

In this embodiment, as shown in fig. 1 and 5, a balance bar insertion hole 124 is formed at one side of the waterproof guide core 12, and a guide slope 1241 is formed on each of the upper inner wall and the lower inner wall of the balance bar insertion hole 124. Correspondingly, a side jack 110 corresponding to the balance bar jack 124 is arranged on the base 11.

Meanwhile, as shown in fig. 2, an upper slot 125 is formed on the upper end surface of the waterproof guide core 12 for the positioning post on the key cap 5 to insert into.

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 clamped into the panel clamping groove 113 of the base 11, and simultaneously, one end of the balance bar 2 is sequentially inserted into the side insertion hole 110 of the base 11 and the balance bar insertion hole 124 of the waterproof guide core 12; meanwhile, the positioning column 51 on the key cap 5 is inserted into the upper clamping groove 125 of the waterproof guide core 12.

The waterproof balance shaft 1 of keyboard that this embodiment provided is applicable to on the long button of keyboard, plays balanced and waterproof effect. For example, as shown in fig. 6 and 7, the keyboard waterproof balance shaft 1 of the present embodiment is applied to a space key of a keyboard, the key switch 4 is installed in the middle, and two keyboard waterproof balance shafts 1 are respectively installed on two sides, and then the balance bar 2 is connected between the two keyboard waterproof balance shafts 1, and the balance bar 2 is combined with the two keyboard waterproof balance shafts 1 to play a role in balancing the whole space key.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that other structures obtained by adopting the same or similar technical features as the above embodiments of the present invention are all within the protection scope of the present invention.
