referring to fig. 1 to 4, a scheme for realizing locking and unlocking of gears by moving a sliding key left and right is provided. The method comprises the following specific steps:

the key cup cover comprises a turnover cover 1, a middle cover 2, an inner cover 3, a clamping piece 4 arranged between the middle cover and the inner cover, and a sliding key 5. The flip cover 1 is hinged on the shaft seat 21 at the rear end of the middle cover 2 through the shaft 11 with the torsion spring, and the clasp 12 or the catching groove at the front end can be inserted into the through hole 22 of the middle cover and is matched with the latch hook 45 on the fastener 4 to form an automatic locking structure.

A step part 31 is formed on the position of the inner cover 3 corresponding to the tangent plane of the clamping piece, and spring seats 32 are respectively formed at two ends of the step part 31; the step part 31 has a step surface 311 and a vertical surface 312, a convex block 313 is formed on the vertical surface 312, and the rest forms a vacant position; the upper end of the bump 313 protrudes from a section of the step surface 311 to form an assembly limit point, which can restrain the engaging member 4 on the step surface 311 and control the feeding stroke of the engaging member.

The front end of the clamping piece 4 is provided with an arc surface 41, two sides of the back of the clamping piece are provided with spring columns 42, the middle of the clamping piece is provided with a hollow part 43, the upper edge of the hollow part 43 is provided with a hook beam 44, the upper edge of the center of the hook beam 44 is provided with a forward locking hook 45, and the clamping piece 4 is arranged on a step surface 311 of the step part in a sliding mode through the hook beam 44 and can perform sliding feeding action under the driving of the sliding key 5; and a spring 6 is arranged between the clamping piece 4 and the inner cover 3, two ends of the spring 6 are correspondingly abutted against the spring seat 32 and the spring post 42, and the spring 6 always keeps the trend that the clamping piece 4 protrudes to lock the flip 1, namely, the basic function of automatically locking the flip when the flip is pressed downwards is realized.

Further, two to three vertical grooves 33 and a ring groove 34 are formed on the outer surface of the inner cover 3; vertical ribs 23 corresponding to the vertical grooves and ring ribs 24 corresponding to the ring grooves are formed on the inner surface of the middle cover 2, the vertical ribs 23 and the vertical grooves 33 form orientation constraint, and the ring ribs 24 which are assembled in place are embedded into the ring grooves 34 to form an assembled constraint structure.

The outer side of the clamping piece 4 is correspondingly provided with a sliding key 5 which protrudes out of the slotted hole 25 of the middle cover, and a lock rod 51 of the sliding key 5 facing inwards penetrates through the clamping piece 4, namely the lock rod 51 penetrates through the hollow part 43 and can move left and right; the inserted lock bar 51 reaches and can slide between the bump 313 of the inner cover and the vacant position, and forms a lock state which can not be pressed and an unlock state which can be pressed; that is, the slide button 5 cannot be pressed, and the engaging member 4 cannot be driven to retract to release the lock of the lid 1. A sliding sheet 7 is sleeved outside the sliding key 5, and a slot 25 on the middle cover of the positioning and shielding cover is formed by the sliding sheet 7; the slide sheet 7 is in double-sided sliding fit between the surface of the clamping piece 5 and the inner surface of the middle cover 2; and a matched two-gear positioning mechanism is arranged between the contact surfaces of the sliding sheet 7 and the clamping piece 4, and the two-gear positioning position corresponds to the gear for locking and unlocking the sliding key 5. Namely, the slide sheet 7 is used for positioning the slide key 5 to form a secondary safety, so that the slide key 5 is prevented from being touched to open the flip cover 1 after being moved unintentionally.

The positioning mechanism refers to an arc protrusion 46 arranged on the surface of the clamping piece 4, two notches 71 matched with the surface of the sliding piece 7 are arranged on the surface of the sliding piece, and the two notches 71 correspond to the locking and unlocking positions of the sliding key 5, namely two definite gears are formed. The structure has the greatest characteristic that the positioning is formed by matching the protrusion 46 and the notch 71 between the contact surfaces of the sliding sheet 7 and the clamping piece 4, when the sliding sheet 7 moves left and right along with the sliding key, the sliding sheet can retreat by virtue of the clamping piece 4 to avoid a moving gap, and the sliding sheet can be easily stirred without influencing the operation; and the positioning device can move in place and form stable and reliable positioning under the action of the spring 6.

In order to achieve the reliability of locking the lid 1, the slide button 5 is moved left and right to avoid malfunction, and the protrusion height of the protrusion 46 on the surface of the engaging piece is smaller than the feeding stroke of the engaging piece 4, preferably smaller than one-half of the feeding stroke.

Referring to fig. 5 and 6, for the scheme that the sliding key moves up and down to lock and unlock the gears, the structure is the same as that of the previous example, and the positions of the protrusion 46 and the notch 71 can be arranged on the left-right symmetrical positions of the clamping piece 4, so that the stress can be balanced, the experience feeling is better, and the scheme is also suitable for the previous example.

In addition, the protrusions 46 and the recesses 71 are preferably cylindrical surface protrusions and cylindrical surface recesses, and certainly, they can be matched by adopting an inclined surface structure, which are equivalent technologies and are conventional technologies.
