Description

Technical Field

[0001] The utility model belongs to the field of door and window locks, and particularly relates to a lock catch as a fixed part of a door and window lock. Background Art

[0002] A door and window lock usually consists of two parts: a lock point and a lock catch. The lock point is installed on the door and window sash as a movable part, and the lock catch is installed on the door and window frame as a fixed part. The opening and closing of the door and window sash drive the lock point to move towards the lock catch. When the lock point and the lock catch are engaged, the door and window is locked, and when the lock point and the lock catch are separated, the door and window is unlocked. Therefore, the installation positions of the lock point and the lock catch need to be consistent. However, the existing lock catches often cannot be aligned with the lock points during installation, resulting in misalignment of the locking positions and inability to lock normally. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a lock catch, which solves the problem of installation and positioning of the lock point and the lock catch.

[0004] The lock catch includes a cover plate and a bottom plate. The cover plate covers the bottom plate, and a longitudinally through cavity is formed between the cover plate and the bottom plate. A card slot is provided on the top surface of the cover plate, and a positioning slot is provided on the bottom plate.

[0005] A notch groove is provided at the joint of the top surface and the side surface of the cover plate. The notch groove extends horizontally and vertically. An inclined hole is provided on one side of the bottom plate, and the notch groove is in the inclined direction of the inclined hole.

[0006] A fixing seat is installed along the inclined hole. The positioning slot is provided on the fixing seat. The fixing seat is provided with a through hole extending into the inclined hole. The positioning slot is parallel to the bottom surface of the bottom plate.

[0007] There are two positioning slots and they are on the same plane.

[0008] There is one notch groove and one inclined hole. The positioning slots are provided on both sides of the inclined hole.

[0009] An L-shaped plate formed by bending upwards is provided on the other side of the bottom plate. Fork plates are provided on both sides of the L-shaped plate. The outer end of the L-shaped plate is connected to one side surface of the cover plate.

[0010] A bent plate formed by bending upwards is provided on one side of the bottom plate. The bent plate is provided on both sides of the inclined hole. The bent plate has the same height as the L-shaped plate. The outer end of the bent plate is connected to the other side surface of the cover plate.

[0011] The bottom plate is provided with mounting holes.

[0012] There are two notch grooves and they are arranged at intervals. There are two inclined holes and they are arranged at intervals. The positioning slots are correspondingly provided on the outside of one inclined hole.

[0013] The bottom plate is provided with a U-shaped plate bent downward, and both sides of the bottom plate are correspondingly inserted into the side surfaces of the cover plate through notches.

[0014] The beneficial effects of the present utility model are as follows: By setting the positioning groove on the bottom plate, the positioning during the installation of the lock catch and the profile groove of the door and window is ensured, so that the lock point can be accurately buckled to the lock catch. A cavity is provided between the cover plate and the bottom plate, enabling the lock point to be clamped inside the cavity, making the locking more reliable. At the same time, the overall weight of the lock catch is reduced, and the production cost is lowered. Description of the Drawings

[0019] The present utility model will be further described in detail below with reference to the drawings.

[0020] The lock catch involved in the present utility model is divided into a single-point lock catch and a double-point lock catch according to the number of notch grooves and inclined holes. The single-point lock catch has one notch groove and one inclined hole, and the double-point lock catch has two notch grooves arranged at intervals and two inclined holes arranged at intervals.

[0021] As shown in Figure 1 and 2 , the single-point lock catch includes a cover plate 1 and a bottom plate 2. The cover plate 1 covers the bottom plate 2. One side of the bottom plate 2 is provided with a bent plate 3 bent upward. The bent plate 3 is arranged on both sides of the inclined hole 11. The bent plate 3 has the same height as the L-shaped plate 6. The outer end of the bent plate 3 is inserted into the other side surface of the cover plate 1 through a notch. The other side of the bottom plate 2 is provided with an L-shaped plate 6 bent upward. Fork plates 7 are provided on both sides of the L-shaped plate 6. The outer end of the L-shaped plate 6 is connected to one side surface of the cover plate 1. A slot is formed between the L-shaped plate 6 and the fork plates 7 for inserting into the profile groove of the door and window frame. A longitudinally through cavity 8 is formed between the cover plate 1 and the bottom plate 2. Two U-shaped card slots 9 opening outward are symmetrically arranged on the top surface of the cover plate 1. The lock point of the door and window sash is locked and unlocked by buckling through this card slot. The setting of the cavity enables the lock point to be clamped inside the cavity, making the locking more reliable.

[0022] A notch groove 10 is provided at the joint of the top surface and the side surface of the cover plate 1. The notch groove 10 extends horizontally and vertically to the end face in a U shape. An inclined hole 11 is provided on one side of the bottom plate 2 through a flanging plate, and the notch groove 10 is in the inclined direction of the inclined hole 11. The outer edge of the flanging plate is inserted into the fixing seat 12. The fixing seat 12 is provided with a through hole 13 extending into the inclined hole 11. Two positioning grooves 14 in the same plane are provided on both sides of the fixing seat 12, and both of the two positioning grooves 14 are parallel to the bottom surface of the bottom plate 2.

[0023] When installing the above single-point lock on the profile groove of the door and window frame, it can be positioned by simply inserting the two positioning grooves into the positioning points on the profile groove, and then a set screw is passed through the notch groove, the inclined hole, and the through hole and fixed to the profile groove of the door and window frame. The cover plate and the bottom plate are firmly fixed by this inclined plug-in threaded connection. At the same time, mounting holes 5 are provided at both ends of the bottom plate 2, and the bottom plate 2 is fixed to the profile of the door and window frame by screws through the mounting holes 5, so that the bottom plate and the cover plate can be doubly fixed to the profile groove of the door and window frame.

[0024] As Figure 3 , 4 shown, the double-point lock includes a cover plate 1 and a bottom plate 2. The cover plate 1 covers the bottom plate 2, and a longitudinally penetrating cavity 8 is formed between the cover plate 1 and the bottom plate 2. Two U-shaped card slots 9 opening outward are symmetrically provided on the top surface of the cover plate 1. The bottom plate 2 is provided with a U-shaped plate 15 bent downward, and both sides of the bottom plate 2 are inserted into the side surfaces of the cover plate 1 through notches. A notch groove 10 is provided at the joint of the top surface and the side surface of the cover plate 1. The notch groove 10 extends horizontally and vertically to the end face in a U shape. An inclined hole 11 is provided on one side of the bottom plate 2 through a flanging plate, and the notch groove 10 is in the inclined direction of the inclined hole 11.
