Abstract

The utility model relates to a fastening device for sliding doors and windows, relating to a locking mechanism on the sliding door and window. The utility model is composed of a first and a second shell bodies, a lock seat, a gear and a rack bar which are installed in the first and the second shell bodies and a lock tongue which penetrates through the two shell bodies and is positioned on the front side of the two shell bodies, and the lock tongue and the rack bar are made into integration, wherein, the first and the second shell bodies are connected with each other and the side faces of the shell bodies are provided with corresponding gear mounting holes; a gear cavity and a slideway of the lock tongue are formed between the first and the second shell bodies, and the center of the gear is provided with a handle mounting hole; a raised ring is separately arranged on each of both side faces on the periphery of the handle mounting hole, and the two raised rings are in movable fit with the inner wall of each gear mounting hole on the two shell bodies. The rack bar engaged with the gear is positioned in the slideway, and the lock tongue is matched with a guiding groove on the lock seat. The utility model has the advantages of reduced components, reasonable structure, firm performance and easy installation, and because each shell body is formed for one time, the utility model also has the advantage of low cost.

Description

Slide door or window locking device

The utility model is a kind of slide door or window locking device, relates to the locking mechanism on a kind of slide door or window.

Slide door or window locking device in the past comprises gear that handle is installed, with the shaft portion of gears engaged and be installed in dead bolt on the connecting rod, also have a backplate in the front side of connecting rod, other has the encapsulation such as a part of a shell with gear and backplate.This locking device complex structure, in conjunction with loose, and it is longer that the connecting rod of dead bolt is installed between its each parts, and its structure is also firm inadequately, damages easily.

The purpose of this utility model is: design a kind of slide door or window locking device reasonable in design, with low cost, strong and reliable.

The utility model is by housing I, II, lock and be installed in gear, the tooth bar in housing I, the II and pass two housings, be positioned at the two housings front side and make with the dead bolt that tooth bar is made as one; Wherein, housing I, II interconnect and the side has corresponding gear installing hole, the slideway of formative gear chamber and dead bolt between housing I, the II, gear centre has the handle installing hole, one prominent ring is respectively arranged on the two sides around the handle installing hole, they and two housings cog installing hole inwall movingly, be positioned at slideway with the tooth bar of gears engaged; Dead bolt cooperates with gathering sill on the lock.

Compared with prior art, the utility model concentrates on other parts on housing I, the II and has reduced parts except that gear, tooth bar, makes it rational in infrastructure, and performance is firm, be easy to install, and because each housing one-shot forming, thereby also have characteristics with low cost.

The shape of housing I, II can have various ways, as two housings shape symmetry, installs relatively; Perhaps middle part, housing I side has groove, and housing II is installed in the groove.Need be formed on like this housing up and down the parts on the position can concentrate on the housing, as the housing installing hole etc., this can make structure of the present utility model more firm.

On this basis, there is a gathering sill groove upper end in housing I rear surface, and the upper end of housing II is step-like, and is embedded in the groove.

Above said other parts or the structure that is formed on the housing comprise that the top that is positioned at housing I groove is shaped on alignment pin, also is with shock absorbing ring on the alignment pin.

In addition, have lock tongue slot on the utility model housing I and the housing II front surface and play certain guide effect.

Then can connect between housing I and the housing II by riveted way.

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

Fig. 1 is the front view of the utility model embodiment;

Fig. 2 is the phantom of Fig. 1 right view;

Fig. 3 is the side view of dead bolt and tooth bar;

Fig. 4 is the lateral view of gear;

Wherein, 1-shock absorbing ring, 2-alignment pin, 3-lock, 4-dead bolt, 5-tooth bar, 6-prominent ring, 7-gear, 8-riveted holes, 9-housing II, 10-housing I, 11-lock tongue slot, 12-installing hole.

As shown in the figure, present embodiment by housing I10, II9, lock 3, be installed in gear 7 in the two housings 9,10, with the tooth bar 5 of gear 7 engagements and pass two housings 9,10 and form with the dead bolt 4 that tooth bar 5 is made as one.Wherein, the side of two housings 9,10 has the gear installing hole, and the middle part of housing I10 opposite side has groove, is with the alignment pin 2 of shock absorbing ring 1 around its top has, and on the housing I10 of alignment pin 2 tops and groove below an installing hole 12 is arranged respectively also.The top of the trailing flank of housing I10 is by a jut form one gathering sill, the height of housing II9 consistent with the height of housing I10 upper groove and itself and be arranged in groove on the housing I10; The upper end of housing II9 is step-like, and is positioned at the gathering sill of housing I10.Two housings 9,10 has lock tongue slot 11 by riveted holes 8 riveted joints on its front surface, dead bolt 4 cooperates with it.Form an inner chamber between the two housings 9,10, gear 7 reaches the tooth bar 5 that meshes with gear 7 and is installed in this inner chamber.There is the handle installing hole at the center of gear 7, respectively has around the handle installing hole prominent ring 6, two prominent rings 6 to be arranged in the gear installing hole of housing I10, II9 on two sides of gear 7, and its prominent ring 6 and gear installing hole are movingly.In the front side of gear 7 is an end slipway, and tooth bar 5 is installed in the slideway, is distributed with on the tooth bar 5 and the big or small square hole that adapts to of the tooth of gear 7.The upper end of tooth bar 5 passes housing 9,10, and its outer end is for being made as the dead bolt 4 of one with it.The mating groove that has dead bolt 4 and alignment pin 2 on the lock 3.
