The present invention aims to provide a sliding door lock structure, which solves the problems in the prior art.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a sliding door lock structure, includes double hook lock body, push-and-pull door section bar and door handle, double hook lock body is including locking box, driving plate, first latch hook and second latch hook, one side of lock box is equipped with the holding chamber, the driving plate slides along vertical direction and sets up in holding the intracavity, first latch hook and second latch hook rotate set up in the holding intracavity, and the driving plate drives first latch hook and second latch hook and rotate to the holding chamber outside and realize locking, and the driving plate has the connection piece along transversely extending, has seted up the spread groove on the connection piece, one side border of push-and-pull door section bar corresponds the spread groove is equipped with through groove, the door handle includes the handle that the symmetry set up, wherein is equipped with the stirring piece that is used for controlling to lock on the handle, be equipped with the connecting rod on the stirring piece, the connecting rod extends to logical groove and pegs graft on the spread groove.

Furthermore, the connecting piece is arranged in the middle of the transmission piece and is formed by bending the connecting piece.

Furthermore, a groove is formed in the sliding door section bar, and a lock box of the double-hook lock body is embedded in the groove.

Furthermore, the terminal surface of lock box is equipped with the separation blade, the separation blade pass through the lock box through the screw with the push-and-pull door section bar is connected.

Compared with the prior art, the invention has the beneficial effects that: through bending the driving plate to form the connection piece to stirring on the handle through the door handle and driving the connecting rod, the connecting rod is pegged graft on the connecting piece, thereby realizes stirring and drives the first latch hook and the second latch hook that the driving plate rotated the double hook lock and lock, and this kind of structure has overcome current glass and has installed and need perforate, the fluting condition on the push-and-pull door section bar, avoids glass impaired, not only can the harmless installation glass body, and is more pleasing to the eye in the appearance simultaneously.

Drawings

Fig. 1 is a schematic perspective view of the present invention.

Fig. 2 is a partial cross-sectional schematic view of the present invention.

In the figure: the double-hook lock comprises a double-hook lock body 1, a lock box 11, a transmission piece 12, a first lock hook 13, a second lock hook 14, an accommodating cavity 15, a connecting piece 16, a connecting groove 17, a sliding door profile 2, a through groove 21, a groove 22, a door handle 3 and a baffle piece 4.

Detailed Description

The invention will be further described with reference to the accompanying drawings in which:

in the description of the present invention, it is to be understood that the terms "central," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the orientations and positional relationships indicated in the drawings only to sub-describe the invention and to simplify the description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be considered limiting of the invention.

Referring to fig. 1 to 2, the sliding door lock structure of the present invention includes a double-hook lock body 1, a sliding door profile 2 and a door handle 3, where the double-hook lock body 1 includes a lock box 11, a transmission plate 12, a first lock hook 13 and a second lock hook 14, one side of the lock box 11 is provided with an accommodating cavity 15, the transmission plate 12 is slidably disposed in the accommodating cavity 15 along a vertical direction, the first lock hook 13 and the second lock hook 14 are rotatably disposed in the accommodating cavity 15, and the transmission plate 12 drives the first lock hook 13 and the second lock hook 14 to rotate outside the accommodating cavity 15 to achieve locking, the transmission plate 12 extends laterally to form a connection plate 16, the connection plate 16 is provided with a connection groove 17, one side edge of the sliding door profile 2 is provided with a through groove 21 corresponding to the connection groove 17, the door handle 3 includes handles 31 symmetrically disposed, wherein the handle 31 is provided with an upper shifting member 32 for controlling the sliding door, the shifting member 32 is provided with a connection rod 33, and the connection rod 33 extends to the through groove 21 to be inserted into the connection groove 17.
