The length symmetric centers of the long waist-shaped through hole and the windproof lock tongue hole are on the same central plane, the transverse waist-shaped counter bore and the long waist-shaped through hole are designed in a centering and vertical mode, and the symmetric central plane of the transverse waist-shaped counter bore is perpendicular to the central planes of the long waist-shaped through hole and the windproof lock tongue hole; the thread end of the eccentric screw shaft penetrates through the transverse kidney-shaped counter bore and the long kidney-shaped through hole to fixedly install and connect the lock catch box with the connected lock hole strip or the door frame by using the nut, and the spring washer is padded below the nut.

Description

Adjustable lock catch

The technical field is as follows:

the utility model relates to an adjustable hasp structure belongs to five metals class product.

Background art:

the door leaf is locked on the door frame through the lock, and the wind-proof latch bolt is designed on the lock usually, and when the door leaf is closed, the door leaf is locked by buckling the lock hole of the door frame through the wind-proof latch bolt lock. The door frame lockhole can not be adjusted under the general condition. The wind-proof latch bolt lock is matched with the lock hole of the door frame, and because of the manufacturing error of the lock hole of the door frame, a gap exists, so that the door leaf shakes, or the latch bolt of the lock cannot accurately enter the lock hole, and the door cannot be locked. The large-gap door leaf can shake, so that the sealing performance of the door leaf and the door frame is poor. Along with the improvement of living standard of people, the air tightness of door products will be more and more valued by customers. Therefore, it is necessary to develop a latch structure capable of adjusting the position of the door frame.

The utility model has the following contents:

based on the demand in not enough and market of above-mentioned technique, the utility model provides a technical solution: it is composed of a lock catch box, an eccentric screw shaft, a spring washer and a nut. The lock catch box is provided with a long windproof lock tongue hole in the center, long convex lock tongue fastening heads are symmetrically designed on the two lateral sides of the windproof lock tongue hole, a horizontal kidney-shaped counter bore and a vertical long through hole are symmetrically designed on the upper and lower longitudinal sides, the length symmetric centers of the long kidney-shaped through hole and the windproof lock tongue hole are on the same central plane, the horizontal kidney-shaped counter bore and the long kidney-shaped through hole are vertically centered, and the symmetric central plane of the horizontal kidney-shaped counter bore is perpendicular to the central planes of the long kidney-shaped through hole and the windproof lock tongue hole; the thread end of the eccentric screw shaft penetrates through the transverse kidney-shaped counter bore and the long kidney-shaped through hole to fixedly install and connect the lock catch box with the connected lock hole strip or the door frame by using the nut, and the spring washer is padded below the nut. The eccentric screw shaft is rotated, the position of the windproof bolt hole of the door frame can be conveniently and accurately adjusted, the sealing requirement of the door leaf and the door frame is met, and the door leaf and the door frame are firmly connected and cannot shake.

In addition, the eccentric screw shaft is provided with an eccentric shaft, a centering cylindrical surface and a screw head with a conical surface cross groove or an inner hexagonal counter bore, one end of the eccentric shaft is provided with threads, the other end of the eccentric shaft is connected with the centering cylindrical surface, and the centering cylindrical surface is concentrically connected with the screw head. The screw head is rotated, the long waist-shaped through hole on the lock catch box is shifted by the eccentric shaft to adjust the inside and outside positions of the lock catch box relative to the doorframe, so that the lock catch box can transversely move left and right relative to the conjoined lock hole strip or the doorframe.

The specific implementation mode is as follows:

the structural features of the present invention will be further described by the following embodiments with reference to the accompanying drawings.

Examples

As shown in fig. 1-4, the utility model relates to an adjustable lock catch, which comprises a lock catch box (1), an eccentric screw shaft (2), a spring washer (3) and a nut (4). The lock catch box (1) is provided with a long windproof lock tongue hole (1-1) in the center, long convex lock tongue fastening heads (1-2) are symmetrically designed on the two transverse sides of the windproof lock tongue hole (1-1), transverse waist-shaped counter bores (1-3) and longitudinal long through holes (1-4) are symmetrically designed on the upper and lower longitudinal sides, the length symmetric centers of the long waist-shaped through holes (1-4) and the windproof lock tongue hole (1-1) are on the same central plane, the transverse waist-shaped counter bores (1-3) and the long waist-shaped through holes (1-4) are in centered vertical design, and the symmetric central plane of the transverse waist-shaped counter bores (1-3) is perpendicular to the central planes of the long waist-shaped through holes (1-4) and the windproof lock tongue hole (1-1); the thread end of the eccentric screw shaft (2) penetrates through the transverse waist-shaped counter bore (1-3) and the long waist-shaped through hole (1-4) to fixedly install and connect the lock catch box (1) with the nut (4) to the door frame of the conjoined lock hole strip (5), and the spring washer (3) is padded below the nut (4). The eccentric screw shaft (2) is rotated, so that the position of the windproof bolt hole of the door frame can be conveniently and accurately adjusted.

In addition, the eccentric screw shaft (2) is provided with an eccentric shaft (2-1), a centering cylindrical surface (2-2) and a screw head (2-3) with a conical cross groove or an inner hexagonal counter bore, one end of the eccentric shaft (2-1) is provided with a thread (2-4), the other end of the eccentric shaft is connected with the centering cylindrical surface (2-2), and the centering cylindrical surface (2-2) is concentrically connected with the screw head (2-3).
