The utility model content:

The purpose of this utility model provides a kind of handle lock structure-improved with regard to being the weak point that exists at prior art, and it has advantage simple in structure, easy to use.

For achieving the above object, the utility model comprises outer handle pipe and the interior handle pipe that is respectively equipped with lock core and knob, has dead bolt in the body of interior handle pipe, dead bolt links to each other with the dead bolt connecting rod that front end has tooth bar, in the tooth bar position of dead bolt connecting rod, be provided with a gear that cooperates with tooth bar, the two ends of gear all are convexly equipped with a sleeve pipe that has a chute, lock core and knob connect a torsion bar that cooperates with sleeve pipe respectively, and two torsion bar front ends then are fixed with the latch that cooperates with chute respectively.

The rear end of described torsion bar is plugged in the lock core sleeve that links with lock core, and the rear end in the lock core sleeve is provided with the compression spring, and the cylindrical shell middle part of lock core sleeve then offers the chute that cooperates with the latch that is fixed on the torsion bar rear end.

Tooth bar position at the dead bolt connecting rod also is provided with the balance weight of clamping gear.

The position of handle pipe is provided with dust cap in dead bolt stretches out.

The beneficial effects of the utility model are: it utilizes two to drive the gear that cooperates with the tooth bar of dead bolt connecting rod upper end with the torsion bar that lock core links to each other with knob respectively, thereby realize opening the door and locking a door action, structure is very simple, not only cost is lower, and also very convenient and reliable in the use.

Below in conjunction with accompanying drawing the utility model is described further:

Accompanying drawing 1 is a three-dimensional combination figure of the present utility model

Accompanying drawing 2 is a three-dimensional exploded view of the present utility model

Accompanying drawing 3 is one of fiting relation figure of gear and lock core and knob

Accompanying drawing 4 be gear and lock core and knob fiting relation figure two

Accompanying drawing 5 be gear and lock core and knob fiting relation figure three

The specific embodiment:

The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

See that accompanying drawing 1 is to shown in the accompanying drawing 3: the utility model comprises outer handle pipe 10 and the interior handle pipe 20 that is respectively equipped with lock core 30 and knob 40, has dead bolt 50 in the body of interior handle pipe 20, dead bolt 50 links to each other with the dead bolt connecting rod 60 that front end has tooth bar 61, tooth bar 61 positions at dead bolt connecting rod 60, be provided with a gear 70 that cooperates with tooth bar 61, the two ends of gear 70 all are convexly equipped with a sleeve pipe 71 that has a chute 711, lock core 30 and knob 40 connect a torsion bar 31 that cooperates with sleeve pipe 71 respectively, 41,

torsion bar

31 and 41 front ends then are fixed with the latch 311 that cooperates with chute 711 respectively, 411.

The rear end of torsion bar 31 is plugged in the lock core sleeve 80 that links with lock core 30, and the rear ends in the lock core sleeve 80 are provided with compression spring 81, and the cylindrical shell middle part of lock core sleeve 80 then offers the chute 801 that cooperates with the latch 312 that is fixed on torsion bar 31 rear ends.

Tooth bar 61 positions at dead bolt connecting rod 60 also are provided with the balance weight 90 of clamping gear 70, and the position that balance weight 90 contacts with gear 70 also is spline-simulating, so that the rotation of gear 70 is more steady

The position of handle pipe 20 is provided with dust cap 21 in dead bolt 50 stretches out.Shown in accompanying drawing 1 and accompanying drawing 2: dead bolt 50 is positioned at the bottom of handle pipe 20, and therefore, dust cap 21 also is positioned at handle pipe bottom; Certainly, dead bolt 50 also can be positioned at handle pipe 20 tops, and this should be decided according to the actual requirements.

In addition, can see from accompanying drawing 2: the upper and lower side between handle pipe 10 and the interior handle pipe 20 outside, be provided with successively from left to right footing, footing lining, on/down to take out, footing lining, footing.Between lock core 30 and lock core sleeve 80, be provided with parts such as lock core cover, lock core holder successively; And between knob 40 and gear 70, then be provided with parts such as knob overcoat, knob holder and pinion stand successively.Above-mentioned parts are all common parts, repeat no more here.

See shown in the accompanying drawing 4: after the user unclamps knob 40, the torsion bar 31 that links to each other with lock core 30 is under the elastic restoring force effect of compression spring 81, insert forward in the sleeve pipe 71, the torsion bar 41 that will link to each other with knob 40 ejects outside sleeve pipe 71 simultaneously, and the chute 711 of latch 411 and sleeve pipe 71 on it is disengaged.At this moment, by key 100 rotational lock cores 30, torsion bar 31 promptly rotates by latch 311 driven gears 70 that its front end cooperates with chute 711 on the sleeve pipe 71, and gear 70 drives dead bolts 50 knee-actions by dead bolt connecting rod 60 again, thereby realizes opening the purpose of door or pinning.
