Abstract

The utility model relates to a practical door lock with an improved structure, which comprises an inner spherical handle, an outer spherical handle, a lock barrel, a bolt and a link mechanism. The outer spherical handle is connected with the link mechanism through an inner sleeve, an elastic locking plate is arranged on the inner sleeve, and the link mechanism puts the bolt. The door lock is characterized in that a lock barrel fixed seat is sheathed outside the inner sleeve and is installed inside the outer spherical handle, a trough is formed on the lock barrel fixed seat along the axial direction, the lock barrel is installed inside the lock barrel fixed seat, a lock barrel head protrudes out of the trough, a punched slot buckled with the elastic locking plate is arranged on the lock barrel fixed seat, a keyhole of the lock barrel protrudes out of the top end of the lock barrel fixed seat, an antiskid corner is arranged at the top end of the lock barrel fixed seat for connecting and fixing with the outer spherical handle, the upper end of the lock barrel fixed seat is connected with a key tube, and the lower end of the key tube is corresponding to the keyhole. The lock barrel fixed seat can be conveniently assembled with and disassembled from the inner sleeve, so as to facilitate replacement of the door lock handle in accordance with the preference of a user; and the lock barrel fixed seat can fix the lock barrel in a better way.

Description

A kind of structure improved practical door lock

Technical field

The utility model belongs to a kind of lockset, belongs to a kind of door lock particularly.

Background technology

Door lock various in style, what generally use now is spherical door lock, comprises inside and outside bundle of spheres hand, lock core, dead bolt and link gear, the ectosphere handle links to each other with link gear by inner sleeve, link gear is stirred dead bolt, and key turns the handle after inserting lock core, and by link gear drive dead bolt, make dead bolt retraction lock body, door is opened, it is spherical that the handle of this door lock mostly is, handle can not arbitrarily be changed with the personal like, and lock core is difficult for fixing in handle.

Summary of the invention

Technical problem to be solved in the utility model is: existing spheric door the basis of lock on, provide a kind of conveniently replaced handle, lock core fixing easily door lock.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of structure improved practical door lock, comprise inside and outside bundle of spheres hand, lock core, dead bolt and link gear, the ectosphere handle links to each other with link gear by inner sleeve, inner sleeve is provided with elastic collet, link gear is stirred dead bolt, it is characterized in that: described inner sleeve is with the lock core holder outward, the lock core holder is installed in the ectosphere handle, the lock core holder has elongated slot vertically, lock core is installed in the lock core holder, the lock core head stretches out elongated slot, the lock core holder is provided with the jet-bedding that fastens with elastic collet, and the keyhole of lock core exposes the top of lock core holder, and the top of lock core holder is provided with and is used for the anti-skidding angle that is connected and fixed with the ectosphere handle, the upper end of lock core holder is connected with the key conduit, and the lower end of key conduit is corresponding with keyhole.

Described anti-skidding angle is curved.

As shown from the above technical solution, the lock of this structure owing to adopted the lock core holder on the one hand can be for convenience detach with inner sleeve, can be changed door lock handle according to the personal like, can make lock core fixing better on the other hand.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the partial enlarged drawing of Fig. 1;

Fig. 3 is the structural representation of lock core holder.

The specific embodiment

Referring to Fig. 1, Fig. 2, Fig. 3, the utility model is the improvement to existing spherical door lock, comprises inside and outside bundle of spheres hand 1, lock core 2, dead bolt and link gear, and ectosphere handle 1 links to each other with link gear by inner sleeve 4, inner sleeve 4 is provided with elastic collet 5, and link gear is stirred dead bolt.

The utility model improvements are: the inner sleeve 4 outer lock core holders 6 that are with, lock core holder 6 is installed in the ectosphere handle 1, lock core holder 6 has elongated slot 7 vertically, lock core 2 is installed in the lock core holder 6, lock core head 8 stretches out elongated slot 7, lock core head 7 can not move in radial direction like this, thereby also that lock core 2 is fixing.The keyhole 3 of lock core 2 exposes the top of lock core holder 6, and the top of lock core holder 6 is provided with to be used for matching with ectosphere handle 1 and merges the anti-skidding angle 9 be connected and fixed, at least 2 of the quantity at anti-skidding angle 9, and anti-skidding angle 9 is curved.The upper end of lock core holder 6 is connected with key conduit 10, and the lower end of key conduit 10 is corresponding with keyhole 3, and key inserts key conduit 10, inserts in the keyhole 3 under the guiding of key conduit 10.

Lock core holder 6 is provided with the jet-bedding 11 that fastens with elastic collet 5, when ectosphere handle 1 is installed, lock core holder 6 is enclosed within outside the inner sleeve 4, elastic collet 5 just in time is stuck in the jet-bedding 11 under the effect of elastic force, and lock core holder 6 and inner sleeve 4 are fixed, when dismounting ectosphere handle, press elastic collet 5, itself and jet-bedding 11 are broken away from, and lock core holder 6 also separates with inner sleeve 4 thereupon, thereby the ectosphere handle is disassembled.
