Technical Field

The invention relates to the technical field of hardware locks, in particular to a lock tongue box.

Background

When the door lock is installed on an aluminum alloy door, a copper door and the like, the lock body is installed on the door, the bolt box is installed on the door frame, because the lock body and the bolt box are respectively installed on the door and the door frame, the installation positions of the lock body and the bolt box cannot be ensured to be very accurate in each installation, if the installation positions are not very accurate, the bolt in the lock body cannot enter the lock box or cannot smoothly enter the lock box, if the installation is not accurate, the bolt box must be dismounted, the position is readjusted, the bolt hole is punched again to install the bolt box, and the installation position of the bolt box cannot be ensured to be accurate, so the bolt box may be dismounted again, the position is readjusted again, the bolt hole is punched again to install the bolt box, and the situation generally occurs when the door lock is installed, thereby not only increasing the labor intensity of workers, still reduced workman's work efficiency, a lot of installation dismantles the spring bolt box and also can cause huge harm to the door frame.

Disclosure of Invention

The present invention is directed to improvements and innovations in the disadvantages and problems of the related art, and provides a latch case that is more convenient to install.

The invention adopts the technical scheme that a bolt box is constructed, and the bolt box comprises a box body and a box body cover, wherein the box body cover and the box body are sequentially arranged at the front and the back of a door frame, fixing lugs are arranged at two ends of the box body, screw holes a are arranged on the fixing lugs, screw holes b are arranged at two ends of the box body cover, a groove a is arranged on the door frame, the screw holes a, the groove a and the screw holes b are sequentially penetrated by screws a, nuts a are arranged on the screws a, and the nuts a and the screws a are matched to clamp the box body and the box body cover and are arranged on the door frame.

Preferably, the box body is provided with a cavity, the box body cover is provided with a square opening a corresponding to the cavity, two fixing strips a are arranged in the square opening a, and the square opening a is divided into a lock tongue opening and two reverse lock tongue openings by the fixing strips a in sequence.

Preferably, be provided with square mouth b on the door frame, be provided with two fixed strip b in the square mouth b, fixed strip b position size and fixed strip a correspond to each other, and be provided with recess b on the fixed strip b, be provided with screw hole c on the fixed strip a, screw hole c and recess b are passed by screw b in proper order, be provided with nut b on the screw b, nut b cooperatees with screw b and installs the box body lid clamp on the door frame.

Preferably, two square blocks are symmetrically arranged on two sides of the lock tongue opening, and the square blocks are respectively contacted with the front side and the rear side of the lock tongue.

Preferably, the box body is a square box body.

Preferably, the box body and the fixing lug are both formed by punching.

The invention has the advantages and beneficial effects that:

because the box body and the box body cover are clamped and installed in the door frame through the matching of the nut a and the screw a, and the screw a is positioned in the groove a, the screw a can move and adjust in the groove a after the nut a is unscrewed, so that the positions of the box body and the box body cover are driven to move and adjust, when the position of the lock bolt box is not accurately installed, the position of the whole lock bolt box can be adjusted by unscrewing the nut, and the lock bolt box can reach an accurate position.
