Abstract

The utility model relates to a spherical door lock which has the advantage of compact structure. An outer spherical handle used by the utility model has simple structure, and distance between the utility model and a door is short. The utility model comprises a lock body, an inner and an outer spherical handles, an inner and an outer baffle plates and a lock tongue. The utility model is characterized in that one side of the outer spherical handle, which faces the outer baffle plate, is provided with a counter bore of which the inside diameter is larger than the outside diameter of a decorative wing on the outer baffle plate, and the bottom of the counter bore is extended with three or more than three supporting posts along the axial direction, wherein, a gap between at least one pair of adjacent supporting posts matches with a positioning rib of a lock head, and the outer end surfaces of the supporting posts are provided with screw holes along the axial direction. When the outer baffle plate is moved outwards the direction of the outer spherical handle, the supporting posts can be extended into inner holes of the decorative wing of the outer baffle plate.

Description

Spherical door lock

Technical field

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

Background technology

Existing spherical door lock comprises lock body, interior ectosphere handle, dead bolt and interior outer baffle, wherein interior outer baffle is installed in the front and rear of lock body respectively, between interior outer baffle and lock body with being threaded, the spacing of two baffle plates equals the thickness of door, and the relative position of outer baffle and lock body makes the fastening position of dead bolt and lock body be in optimum state in regulating; On November 16th, 1994 disclosed Chinese patent bulletin: disclose application number among the CN2182840Y and be 93226808 patent application, disclose the structure of the spherical door lock of a kind of multifunctional burglary-resistant in this patent application; The structure of this spherical door lock is too big away from the distance of door-plate because of reserving the investigation mission outside the city or town space to outer baffle with the same its ectosphere handle outdoors of existing common door lock, the gate facing the street after loading onto this spherical door lock, when wanting outside it, to refill a fan security door, may be withstood and security door can not be shut by the ectosphere handle.

Summary of the invention

In order to solve the ectosphere handle that exists in the existing spherical door lock from the too big problem of door distance, the utility model proposes a kind of spherical door lock, its compact conformation, employed ectosphere handle are simple in structure, shorter from the distance of door.

Technical scheme:

A kind of spherical door lock, comprise lock body, interior ectosphere handle, interior outer baffle, dead bolt, it is characterized in that the ectosphere handle has the counterbore of internal diameter greater than the fin external diameter on the outer baffle towards outer baffle one side, the counterbore bottom is stretched out the support column more than three or three vertically, wherein have at least the gap between a pair of adjacent support column and the positioning bar of tapered end to match, the outer face of support column is provided with screw vertically, the rotation outer baffle makes it when ectosphere handle direction moves, support column can stretch into the endoporus of the fin of outer baffle, and fin stretches in the counterbore of ectosphere handle.

Beneficial effect:

Owing to adopted technical scheme described in the utility model, when regulating the position of outer baffle and lock body, the fin on the outer baffle can stretch in the counterbore of ectosphere handle, saved the space, shorten the distance of the ectosphere handle and the shop front, do not influenced outer installing an iron door to guard further against burglars, satisfied user's requirement.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the three-dimensional view of spherical door lock described in the utility model.

Fig. 2 is that the spherical door lock among Fig. 1 embodiment is installed in the internal construction schematic diagram of part outdoors.

Fig. 3 is the left view of ectosphere handle among Fig. 2.

Fig. 4 is the schematic diagram after the outside ball handle of outer baffle direction is regulated among Fig. 2.

Among the figure 1, the ectosphere handle, 2, outer baffle, 3, lock body, 4, Internal baffle, 5, endosphere handle, 6, dead bolt, 7, tapered end, 8, preceding logical, 9, the switch tube, 10, screw, 101, counterbore, 102, support column, 1021, screw, 103, gap, 104, through hole, 21, fin, 31, outer end screw thread, 32, inner screw thread, 701, positioning bar.

The specific embodiment:

As seen, described spherical door lock comprises lock body 3, interior ectosphere handle 5 and 1, interior outer baffle 4 and 2, dead bolt 6 from Fig. 1, Fig. 2, Fig. 3.Ectosphere handle 1 has through hole 104 allows key stretch in the tapered end 7, it has counterbore 101 towards outer baffle 2 one sides, counterbore 101 bottoms are stretched out three support columns 102 vertically, gap 103 between the wherein a pair of adjacent support column matches with the positioning bar 701 of tapered end 7, tapered end 7 is played the role of positioning, has screw 1021 on the support column 102, preceding logical 8 and 102 of support columns with screw 10 tapered end 7 is fixed in the outer handle 1, cover switch tubes 9 in preceding logical 8, switch tube 9 links with tapered end 7; On establish the outer baffle 2 usefulness screw threads of annular fin 21 and the outer end screw thread 31 on the lock body 3 links.

From Fig. 4 as seen, rotation outer baffle 2 makes it when ectosphere handle 1 direction is moved, and the fin 21 on the outer baffle 2 stretches in the counterbore 101 of ectosphere handle 1, has shortened the distance of ectosphere handle outermost end and outer side of door.
