Abstract

The utility model relates to a handle lock structure which comprises a lock body and a handle. The lock body comprises a pair of lock levers, a fixed sleeve and a lock shaft, wherein a cross section of the fixed sleeve is in the structure of a shape like a Chinese character 'ao' and fixed on a door, the middle of the fixed sleeve is provided with a through hole, and two sides of the fixed sleeve are respectively provided with a square hole. One ends of the lock levers are respectively provided with a rectangular tooth structure, and the lock levers are oppositely inserted into the square holes arranged on the fixed sleeve. The lock shaft is arranged in the through hole in the fixed sleeve, one end of the lock shaft is in touch connection with the handle through a metal insert and is fastened by a screw, the other end of the lock shaft is located in a concave groove of the fixed sleeve and connected with a sector gear which is used to match with the rectangular tooth structures of the lock levers, and the sector gear is fastened by the screw. Due to the fact that the sector gear is in drive connection with the rectangular structures of the ends of the lock levers in a meshed mode, the handle drives the sector gear to rotate, so the lock levers are driven to move up and down, and the lock locking or unlocking is conveniently achieved.

Description

A kind of handle door lock structure

Technical field

The utility model relates to door latch structure, especially has the door latch structure of handle.

Background technology

The door lock operation of handle type structure is laborsaving, at present, common handle type door lock, its structure comprises lock body and handle, and said handle is connected on the lock body through fixed cover, and said lock body and handle adopt wooden type of material, low, fragile, the often replacing of intensity; Or adopt high strength and high hardness material such as metal species owing to produce friction between handle and the fixed cover, use a period of time after, have choking phenomenon between handle and the fixed cover, use dumb.

Also there is following shortcoming in said structure:

(1) door lock of employing all metal construction, its intensity and hardness are all higher, can not judge whether locking bar is unimpeded, when having or not lock to advance jam plate, because the continuous application of force of handle is prone to cause the distortion of door lock, even make door lock produce the phenomenon of fracture;

(2) in the season of cold, grip the metal handle, comfort level is poor;

(3) the metal handle is heavier, thereby increases cost of transportation.

The utility model content

The applicant provides handle door lock structure a kind of rational in infrastructure, easy to operate, thereby has improved the use flexibility of handle to above-mentioned door latch structure shortcoming of the prior art, has reduced cost.

The technical scheme that the utility model adopted is following:

A kind of handle door lock structure comprises lock body and handle, and said lock body comprises a pair of locking bar, fixed cover and lock shaft, and said fixed cover cross section becomes " recessed " shape structure and is fixed on the door, and said fixed cover middle part has through hole, and its both sides have square opening; Said locking bar end is provided with the rectangular teeth structure, and a pair of locking bar inserts fixed cover relatively and opens in the square opening; Said lock shaft is installed in the through hole that fixed cover opens; Said lock shaft one end connects the sensation handle through metal insert; And it is fastening through screw; The lock shaft other end is positioned at the fixed cover groove and connects the sector gear that matches and use with the rectangular teeth structure of locking bar, and said sector gear is fastening through screw.

Its further technical scheme is:

Said metal insert quadrate structure;

Said sensation handle can adopt nylon material.

The beneficial effect of the utility model is following:

The utility model is through the rectangular teeth structure engages transmission of sector gear and locking bar end, and handle drives the sector gear rotation, thereby drives moving up and down of locking bar, has realized the locking of door lock easily and unclamps.

The utility model adopts the sensation handle of nylon material, and is connected on the lock shaft of fixed cover through metal insert, has overcome low, the flimsy defective of the wooden handle strength of available technology adopting, and the defective of metal handle comfort level difference.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described.

As depicted in figs. 1 and 2; The described a kind of handle door lock structure of the utility model; Lock body and sensation handle 1, lock body comprises a pair of locking bar 7, fixed cover 6 and lock shaft 4, the cross section of fixed cover 6 becomes " recessed " shape structure also to be fixed on the door; Fixed cover 6 middle parts have through hole 5, and its both sides have square opening 9; Locking bar 7 ends are provided with rectangular teeth structure 8, and a pair of locking bar 7 inserts 6 of fixed covers relatively and opens in the square opening 9; Lock shaft 4 is installed in the through hole 5 that fixed cover 6 opened; Lock shaft 4 one ends connect the head of sensation handle 1 through metal insert 3; And be positioned at fixed cover 6 grooves through screw 2-1 lock shaft 4 other ends and connect the sector gear 10 that matches and use with locking bar 7 rectangular teeth structures 8, it is fastening that sector gear 10 passes through screw 2-2; Metal insert 3 quadrate structures, metal insert 3 can guarantee the bonding strength of sensation handle 1 and lock shaft 4.

The operating principle of the utility model is following:

Reverse sensation handle 1 through manual work, sensation handle 1 rotates and drives and then lock shaft 4 rotations of metal insert 3 that its head is inlayed, thereby sector gear 10 is rotated in fixed cover 6; Rectangular teeth structure 8 engaged transmission of the gear teeth and locking bar 7 through sector gear 10 have realized moving up and down of locking bar 7, and are as shown in Figure 3; Reverse sensation handle 1 downwards, drive sector gear 10 and turn clockwise, a pair of locking bar 7 moves in square opening 9; When the two ends of locking bar 7 break away from the snap close on the door, unlocking condition; As shown in Figure 4, up reverse sensation handle 1, sector gear 10 is rotated counterclockwise, thereby it is mobile to square opening 9 outside respectively to drive a pair of locking bar 7, when the snap close on the access door of the two ends of locking bar 7, locking state.

The described sensation handle of the utility model 1 adopts nylon material, and sensation handle 1 and metal insert 3 through nylon material mutually combine, can through operating grip feel determine whether door lock good; Locked when door lock, when reversing sensation handle 1 again, sensation handle 1 can deform, and then stops twisting sensation handle 1 this moment, and door lock is locked fully.The sensation handle 1 of the utility model can be prone to be adapted to surrounding enviroment in its surface colour in addition, increases class.

More than describing is the explanation to the utility model, is not the qualification to utility model, and the utility model institute restricted portion within the protection domain of the utility model, can be done any type of modification referring to claim.
