Description

The reinforcing structure of lock body

Technical field

The utility model relates to a kind of lockset, refers to a kind of reinforcing structure of lock body especially.

Background technology

Existing general tubular Lock structure (as shown in Figure 1), it comprises that roughly an outside lock body 11, one an inboard lock body 12 and a lock bolt 2 constitute; Described outside lock body 11 comprises: an overcoat dish 112, one an outer handle group 111 and an outer final drive gear 113; Described overcoat dish 112 is discoid body, final drive gear 113 outside the central means one of disk body; And in the outer handle group 111 of the disk body of overcoat dish 112 outside removable mounting one, and the inside bottom of disk body has the two axial back nuts 114 of settings, and described back nut 114 is hollow form, and its inwall has screw thread; Described inboard lock body 12: comprise final drive gear (not shown) in cover dish 122 in, the Internal handle group 121 and; Cover dish 122 also is discoid body in described, final drive gear (not shown) in the central means one of disk body, final drive gear has a hole (not shown) in described, can plant for the driving tube 115 of outer final drive gear 113, cover dish 122 has the two-screw hole 124 that aligns setting with back nut 113 in described, screw togather locking with the back nut 113 of described overcoat dish 112 respectively in order to provide two-screw 6 to wear described screw hole 124 by the inboard, cover dish 122 is secured on the both sides of door-plate 3 with overcoat dish 112 in making.

Because door-plate 3 is for ease of installing aforesaid lock body 1, on door-plate 3, be drilled with a columniform lock body installing hole 32 in advance, and be drilled with a less vertical lock bolt installing hole 31 at door-plate 3 sides, described lock bolt installing hole 31 can provide lock bolt 2 to pack into from door-plate 3 sides, and pass the panel 22 of lock bolt 2 with two screws 25, locking lock bolt 2 is on door-plate 3, described lock bolt 2 has two back nut installing holes 23 and has a driving tube installing hole 24 23 of two back nut installing holes, can provide by door-plate 3 outsides two back nuts 114 of described overcoat dish 112 and the driving tube 115 of outer final drive gear 113 are worn respectively, by door-plate 3 inboards the borehole jack of the interior final drive gear of interior cover dish 122 is gone into described driving tube 115 then, and two-screw hole 124 is aligned with back nut 114 respectively, and screw togather locking by screw 6 and back nut 114, inboard lock body 12 is secured on the both sides of door-plate 3 with outside lock body 11, when making rotation outer handle group 111 or internal handle group 121, all but the interlock driving tube 115, produce with the plunger latch head 21 that drives lock bolt 2 and remove adduction; Yet door-plate 3 only can be with two-screw 12 with interior cover dish 122 and firmly locking of overcoat dish 112 with combining of 112 on overcoat dish with the interior cover dish 122 of lock body 1, so twisting resistance, the shearing resistance of lock body 1 integral body are poor, knocked with treasure by the thieves or robbers who act under cover of night or reverse overcoat dish 112 and lock body is destroyed with binder.

The utility model content

The purpose of this utility model is to provide a kind of reinforcing structure of lock body, and it can increase the effect of tubular lock opposing torsion and shearing resistance, to improve safety.

For achieving the above object, technical solution of the present utility model is:

A kind of reinforcing structure of lock body, this reinforcing structure is installed in this lock body, and it has one first vertical ring, this first vertically ring have at least one engaging piece, this engaging piece has two inclined-planes, this two chamfered portion or all embed in the ring wall of the lock body installing hole that a door-plate had.

First of described reinforcing structure vertically encircles and connects a lateral loops, and this lateral loops connects one second and vertically encircles.

Second vertical ring of described reinforcing structure has an engaging piece and is meshed with the engaging piece that this lock body is had.

Described first vertically encircles connection one dish, in this dish two holes is set, and has a centre bore between this two hole.

Described first engaging piece that vertically encircles is connected with a lateral loops.

The angle on two inclined-planes of described first engaging piece that vertically encircles acutangulates.

After adopting such scheme, because the utility model is set up a reinforcing structure between the outside of lock body lock body and inboard lock body, described reinforcing structure can be a setting element, borrow described setting element to have the lock body installing hole that engaging piece can embed door-plate, destroy with the twisting resistance and the shearing resistance that strengthen outside lock body.
