First 5 and reset spring 6 be mounted in accommodating cavity.
Specifically, pedestal 1 is fixed on above thin film circuit, offers through-hole (not shown) among pedestal 1, through-hole inwardly prolongs
It stretches to form positioning column 11,11 inner sidewall of positioning column is equipped with boss 12.Rotating cylinder 4 is hollow structure, is equipped with pressure bullet in rotating cylinder 4
One end of spring 7, compression spring 7 is connect with contact 5, and the other end is connected to the bottom end face of handle 3, and the rotating cylinder is placed in positioning
The top of column 11, by the touching that positioning column 11 can be put in positioning column 11 and passed through when pressuring press handle act in wiring thin film (not shown)
Point realizes the conducting of wiring thin film.The lateral wall at the top of rotating cylinder 4 is equipped with the sliding part 41 to extend radially outwardly along rotating cylinder 4, and two
A sliding part 41 is on same straight line, is respectively equipped with oblique sliding slot 31 on the position of corresponding two sliding parts 41 of handle 3, is slided
Part 41 is placed in corresponding oblique sliding slot 31 and can make 4 radial rotating of rotating cylinder when sliding.The lateral wall of 4 bottom of rotating cylinder is equipped with
Convex block 42, the bottom surface of convex block 42 can be contacted with boss top surface to be supported.
When by pressuring press handle 3, handle 3 drive rotating cylinder 4 move downward, the convex block 42 of 4 bottom of rotating cylinder with it is convex in positioning column 11
The contact of platform 12 supports and compresses the compression spring 7 in rotating cylinder 4.Continue by pressuring press handle 3, the sliding part 41 on 4 both sides of rotating cylinder is along oblique
Radial force is generated when sliding to sliding slot 21 forces rotating cylinder 4 to rotate, and the sliding part 41 on rotating cylinder 4 is by under oblique sliding slot 21 at this time
End slides into the upper end of oblique sliding slot 21.After rotating cylinder 4 drives convex block 42 to turn to certain angle, convex block 42 connects with the disengaging of boss 12
It touches, the 7 abrupt release pressure of compression spring in rotating cylinder 4, and the sliding part 41 on rotating cylinder 4 is pushed back to tiltedly by 21 upper end of sliding slot
To 21 lower end of sliding slot and strike on the inner sidewall of oblique sliding slot 21 and then issue loud sound.
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.
Further, compression spring 7 is equipped in rotating cylinder 4, compression spring 7 is inside rotating cylinder 4, and the one of compression spring 7
End is connected to contact 5, the other end is connected to the bottom surface of handle 3.
Further, as shown in figure 5, 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 is installed in the sliding slot 21 of glue lid 2 by trapezoidal slide block 32, and 3 quilt of handle
It is limited in sliding slot 21, and then limits 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 is by rotating cylinder 4
It pushes, 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 in rotating cylinder 4 is compressed simultaneously.Continuing by pressuring press handle 3, handle 3 overcomes the restoring force of reset spring 6 to move 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, on rotating cylinder 4
Sliding part 41 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 certain angle
Afterwards, convex block 42 is disengaged with boss 12, the 7 abrupt release pressure of compression spring in rotating cylinder 4, and by sliding part 41 by oblique cunning
The upper end of slot 21 pushes back to oblique 21 lower end of sliding slot and impact issues loud clear and melodious touching on the inner sidewall of oblique sliding slot 21
Sound.The fixed contact 5 in 4 bottom end of rotating cylinder passes through positioning column 11 and acts on wiring thin film at the same time, makes on wiring thin film
Contact contact is conductive, and then realizes the on-off of 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 is also released, and rotating cylinder 4 is returned to initial position in position under the action of compression spring 7.
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
The operation feeling of key can be enhanced when pressing good hand touch, and pressing and issue loud sound, while also there is film
The features such as keyboard waterproof, dust-proof and long service life.The utility model structure is simple, and pressing stroke length, good hand touch can issue
Loud sound reduces wrong press and occurs, and leakproofness is strong, can be with waterproof and dustproof, therefore is suitable for substituting existing product to be answered extensively
With.
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.
