Detailed Description

Embodiments of the invention are further described below with reference to the accompanying drawings:

as shown in the figure, the invention provides a key button capable of freely setting a key pulling-out position, which comprises a shell 1 and a lock sleeve 3 suitable for being installed in a central hole of the shell, wherein a lock cylinder 2 is arranged in the lock sleeve, the lock sleeve 3 is directly sleeved in the central hole of the shell 1 and forms circumferential limit fit with the shell 1, when in use, the lock cylinder 2 is rotated and does not drive the lock sleeve to act, at least 6 grooves are circumferentially arranged on the inner wall of the lock sleeve 3, the grooves are uniformly distributed radially along the circumferential direction of the central hole, the number of the grooves is 6, the grooves are sequentially arranged along the inner wall of the lock sleeve, two symmetrically arranged grooves are defined as lock cylinder initial plug grooves 31, the lock cylinder initial plug grooves 31 are vertically penetrated and arranged for initial lock cylinder plug fit, 2 selective plug grooves 32 are respectively distributed on two sides of the lock sleeve at intervals in a direction corresponding to the initial plug grooves, and the limit plug grooves are respectively arranged on two sides of the lock sleeve in a direction corresponding to the key, and the lock sleeve can be prevented from being pulled out by limiting whether the limit plug grooves are used for the key can be selectively pulled out by the key plug grooves, and whether the limit plug grooves are used for realizing the key plug-in the key plug grooves are correspondingly or not.

The limiting member 4 can be movably or destructively connected with the lock cylinder selection plug groove so as to perform specific angle selection when the direction needs to be changed.

Example 1

The groove is a dovetail groove, namely the inner width of the groove is larger than the width of the opening, the limiting piece is matched with the dovetail groove, the limiting piece and the dovetail groove form sliding fit, and when the limiting piece is inserted into the groove, the limiting piece cannot fall out from the inner side, so that the phenomenon of locking the lock cylinder occurs. Meanwhile, in the embodiment, the limiting piece is matched with the groove in a sliding mode, so that the limiting piece can be detached.

And set up breach 41 in the locating part inboard, when needs change key pull out the direction, can utilize this breach to take out the locating part, change, it is comparatively convenient to operate, perhaps when the assembly is wrong, also can utilize this breach 41 to take out the locating part, and the customer can be very convenient set up different pull out the position according to the demand of oneself different period.

Example 2

The limiting piece 4 is connected with the groove through the breakable connection structure 5, namely, the limiting piece is arranged in the corresponding groove in advance, the breakable connection structure of the corresponding limiting piece is broken when needed, and the key with different angles can be pulled out to be arranged after being taken out.

The number of the breakable connection structures 5 is 3, two symmetrical or asymmetrical structures are arranged on two sides of the limiting piece, one breakable connection structure is arranged between the limiting piece and the inner wall of the groove, the breakable connection structure can be a thinner connection rib, the limiting piece is directly fixed by the connection rib, the connection rib can be directly broken due to the thinner diameter of the connection rib, and meanwhile, the breakable connection structure can be reset by rotating 180 degrees after being mistakenly arranged.

The inner sides of the upper end or the lower end or the two ends of the limiting piece are provided with inclined planes 42, and the limiting piece is more convenient to pry out.

The bottom of the lock sleeve is circumferentially provided with a plurality of protruding blocks 33, and the inner step of the shell is provided with a plurality of limit grooves 11 which are matched with the protruding blocks. The centre bore of shell is the shoulder hole, sets up a plurality of spacing grooves on the step of shoulder hole circumference, just the width of spacing groove can be unequal, and the spacing groove symmetry of same width sets up, and the bottom of lock sleeve then circumference be equipped with a plurality of lugs with this spacing groove looks adaptation, inlay through the lug and establish in the spacing inslot that corresponds, realize the spacing cooperation of circumference rotation, the design of the spacing groove and the lug that the width is unequal simultaneously also can play the effect of mistake proofing, and the symmetry sets up, then can make this lock sleeve reuse after 180 is rotated to circumference, avoided the setting that the part that the locating part stripping position mistake led to appears, satisfy the different extraction demands of customer in different periods simultaneously.

The examples should not be construed as limiting the invention, and any modifications based on the spirit of the invention should be within the scope of the invention.
