Ring-shaped step 43 is close to the dome portion 71 of compression spring 7, and the ring-shaped step 43 makes its positioning for support pressure spring 7
It is fixed in rotating cylinder 4, compression spring 7 is prevented to be subjected to displacement.
Further, as shown in Fig. 2, 4 bottom end of rotating cylinder is fixed with contact 5, contact 5 is installed in positioning column 11 and can be along fixed
The inner sidewall movement of position column 11.When handle 3 is pressed, contact 5 is moved downward by rotating cylinder 4, and contact 5 can pass through and determine
Position column 11 acts on the contact in wiring thin film (not shown), realizes the conducting of wiring thin film.Wherein, the keyboard press button structure is also
It may be mounted in PCB circuit board, by pressing pressuring press handle 3, the metal touching for acting on the contact 5 on rotating cylinder 4 in PCB circuit board
Point realizes the conducting of the key switch, since above-mentioned part is the prior art, does not just tire out one by one chat here.
Further, as shown in figure 4, the lateral wall of handle 3 is equipped with trapezoidal slide block 32, the inner sidewall of glue lid 2 is equipped with and ladder
The sliding slot 21 that shape sliding block 32 is slidably connected, handle 3 be installed on glue lid 2 by trapezoidal slide block 32 and be restricted in sliding slot 21 into
And limit its stroke.
Further, 11 outer cover of positioning column is equipped with reset spring 6, and reset spring 6 is placed between handle 3 and pedestal 1, multiple
Position 6 one end of spring is contacted with the top surface of pedestal 1, the position that the other end is contacted and is placed in below oblique sliding slot with the inner bottom surface of handle 3
It sets, which is used to provide the restoring force of rebound for handle 3.
Working principle:
When not pressing pressuring press handle 3 (original state), reset spring 6 pops up handle 3, and compression spring 7 and little spring 8
Rotating cylinder 4 is pushed, the sliding part 41 on 4 both sides of rotating cylinder is placed in the oblique sliding slot 31 of handle 3.
When by pressuring press handle 3, a part of pressure on handle 3, which is applied on reset spring 6, makes its slight deformation, 3 band of handle
Turn cylinder 4 is moved downward and is protruded into positioning column 11, and the convex block 42 on rotating cylinder 4 is contacted with the boss 12 in positioning column 11 and supported,
The compression spring 7 and little spring 8 in rotating cylinder 4 are compressed simultaneously.Continue by pressuring press handle 3, handle 3 overcomes the restoring force of reset spring 6
It moves downward, radial force is generated when the sliding part 41 on 4 both sides of rotating cylinder is slided along oblique sliding slot 31 and forces 4 radial rotating of rotating cylinder,
Sliding part 41 on rotating cylinder 4 is slided to the upper end of oblique sliding slot 21 by the lower end of oblique sliding slot 21.Rotating cylinder 4 drives convex block 42 to turn to
After certain angle, convex block 42 is disengaged with boss 12, the 8 abrupt release pressure of compression spring 7 and little spring in rotating cylinder 4, and
Sliding part 41 is pushed back into oblique 21 lower end of sliding slot and impact on the inner sidewall of oblique sliding slot 21 by the upper end of oblique sliding slot 21
Issue loud clear and melodious touching sound.The fixed contact 5 in 4 bottom end of rotating cylinder passes through positioning column 11 and acts on thin film wire at the same time
Road makes the contact on wiring thin film contact on-off that is conductive, and then realizing membrane keyboard.
When release is applied to the pressure on handle 3,6 abrupt release restoring force of reset spring pops up handle 3, simultaneously
The restoring force of 4 internal pressure spring 7 of rotating cylinder and little spring 8 is also released, position under the action of compression spring 7 and little spring 8 of rotating cylinder 4
It is returned to initial position.
The utility model solves the problems, such as membrane keyboard not by axis by rotating cylinder, and increased handle and rotating cylinder are not only
Operation feeling and the sending of key can be enhanced when having the advantages that mechanical keyboard pressing stroke length, good hand touch, and pressing
Loud sound, while also having the characteristics that membrane keyboard waterproof and dustproof and long service life.The utility model structure is simple,
Pressing stroke is long, good hand touch, can issue loud sound, reduces wrong by occurring, and leakproofness is strong, can with waterproof and dustproof, because
This is suitable for substituting existing product to be widely used.
The foregoing is merely this patent preferred embodiments, not limit this patent range, all using specification and attached
Equivalent structure or equivalent flow shift made by figure content is directly or indirectly used in other relevant technical fields, belongs to
The scope of this patent.
