Example 2

Please refer to Fig. 5-6 and Fig. 1, a further improvement is made on the basis of Embodiment 1: In order to make the key 2 protected against dust, the outer wall of the instrument body shell 1 is provided with a protection device 3 above the key 2, The protection device 3 includes a rotating shaft 32, and a supporting plate 31 is fixed on the outer wall of the instrument body casing 1 above the button 2. The supporting plate 31 is U-shaped, and the U-shape facilitates the storage of the rotating shaft 32 by the supporting plate 31.

Wherein, the inner wall of the support plate 31 is provided with a through hole 34, and the two ends of the rotating shaft 32 are inserted into the inner wall of the through hole 34. The through hole 34 is to facilitate the rotation of the rotating shaft 32 on the inner wall of the supporting plate 31. The outer wall is wound with a dust-proof film 33, the dust-proof film 33 is made of a flexible plastic transparent material that can be bent in the prior art, and one end of the dust-proof film 33 is fixed on the outer wall of the rotating shaft 32, and the other end is vertical Down, it is convenient for the rotating shaft 32 to roll up the dustproof film 33 .

In addition, because the dustproof film 33 is transparent, the use of the button 2 will not be hindered.

In addition, since the dust-proof film 33 is tiled on the outside of the key 2, due to the influence of the self-gravity of the dust-proof film 33, the dust-proof film 33 and the key 2 will not be kept in close contact when the dust-proof film 33 is pressed.

The falling off of the shaft 32 enables the rotation shaft 32 to be limited when the inner wall of the support plate 31 rotates, which facilitates the release of the dust-proof film 33 .

Wherein, the outer wall of the cover plate 36 is fixed with a return spring 39, and the end of the return spring 39 away from the cover plate 36 is fixedly connected with the inner wall of the through hole 34. The return spring 39 provides an elastic force to the outside, so that the rotating shaft 32 can be inserted into the through hole. When closing the inner wall of the hole 34 , the cover plate 36 will limit the rotation shaft 32 in time under the action of the return spring 39 , so as to prevent the separation between the rotation shaft 32 and the through hole 34 .

Wherein, the outer side wall of cover plate 36 is rotated with T-shaped bar 38, and the outer side wall of T-shaped bar 38 is sleeved with threaded rod 35, so that threaded rod 35 is in the process of rotating, and T-shaped bar 38 can not follow threaded rod 35 Rotate together, one end of the threaded rod 35 extends through the inner wall of the through hole 34 to the outside of the support plate 31 , and the threaded rod 35 can rotate with the instrument body shell 1 .

When the dust-proof film 33 needs to be replaced, it is only necessary to turn the threaded rod 35 so that the threaded rod 35 drives the T-shaped rod 38 to move, and when the T-shaped rod 38 moves, the T-shaped rod 38 will drive the cover plate 36 to surround the fixed rod 310 The rotation of the cover plate 36 breaks away from the limit to the rotating shaft 32, thereby facilitating the replacement of the dust-proof film 33, so that the dust-proof film 33 is damaged during long-term use, and the key 2 can be protected by timely replacement.
