Description

Technical Field

[0001] The utility model relates to a glass door lock, in particular to a glass door lock with a stable structure and being light and thin. Background Art

[0002] With the development of society, glass doors are used in more and more scenarios, such as general doors, cabinet doors, window doors, etc. However, the glass door locks on the market are complex in structure, so the integrated body is relatively large and heavy, which is not suitable for some doors such as cabinet doors, window doors and some light glass doors, bringing inconvenience to people's lives. Utility Model Content

[0003] The purpose of the utility model is to provide a glass door lock, which, in addition to a lock body and a lock core, can be completely composed of a lock tongue with a V-shaped opening and a swing arm, so it can be made very small and thin according to needs.

[0004] The technical solution of the utility model is based on the face cover, base, splint, lock core, spacer, lock tongue, swing arm and torsion spring, and is characterized in that a cavity is provided in the middle of the base, four corners of the cavity are respectively provided with columns with screw holes, one end of the swing arm is hingedly installed with the column in the front left side through the torsion spring, and the other end extends toward the tail of the base, a card column is raised at the middle left side of the top of the swing arm, the lock tongue is arranged in the cavity and above the swing arm, the tongue of the lock tongue extends forward through the tongue hole of the base, a V-shaped opening is provided in the middle of the tail of the lock tongue at a position relative to the lock hole of the base, a bayonet corresponding to the card column is provided at the middle and tail of the left outer side surface of the lock tongue, respectively, a bayonet corresponding to the paddle of the lock core is provided at the tail of the left inner side surface of the lock tongue, the lock core is inserted into the lock hole of the face cover and the base and installed and passes through the V-shaped opening of the lock tongue.

[0005] The utility model discloses a guide column protruding from the tail end of the top right side of the lock tongue, a splint is superimposed on the top of the base, and strip holes are provided at corresponding positions of the splint and the guide column. The guide column is inserted into the strip hole so that the guide column can guide the lock tongue to move forward and backward in a straight line. When the key is inserted into the lock cylinder and the paddle of the lock cylinder is rotated, the paddle can slide into or out of the slot on the inner left side of the lock tongue, forcing the swing arm to swing left and right and the lock tongue to move forward and backward, so that the slot is switched between the two slots in the middle and tail of the outer left side of the lock tongue, thereby completing the opening and closing action of the lock.

[0006] The working principle of the utility model is that when the key is inserted into the lock cylinder and the lock cylinder is rotated 90 degrees counterclockwise, the pick slides into the inner slot on the left side of the lock tongue and forces the swing arm to swing to the left, causing the card column to slide out of the tail slot on the left outer side of the lock tongue. At this time, the pick continues to be rotated to drive the lock tongue to move backward until the card column slides into the middle slot on the left outer side of the lock tongue, completing the unlocking action. Similarly, rotating the pick clockwise is the opposite locking action.

[0007] The utility model has the advantages of simple structure, stable and reliable operation, small size and lighter weight, and can better adapt to various glass doors. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 2 This is a schematic diagram of the internal three-dimensional structure of the utility model;

[0010] Figure 3 This is another schematic diagram of the internal three-dimensional structure of the utility model;

[0011] Figure 4 It is a schematic diagram of the exploded three-dimensional structure of the utility model. DETAILED DESCRIPTION

[0012] according to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the utility model has a cover 1, a base 2, a splint 3, a lock core 4, a spacer 5, a lock tongue 6, a swing arm 7, a torsion spring 8, and the inner surfaces of the base 2 and the cover 1 are respectively provided with a spacer 5. The characteristic is that a cavity is provided in the middle of the base 2, and four corners of the cavity are respectively provided with columns 2.1 with screw holes. The front end of the swing arm 7 is hingedly mounted with the left front column through the torsion spring 8, and the rear end extends toward the tail direction of the base 2. A card column 7.1 is raised at the middle of the left side of the top of the swing arm 7. The lock tongue 6 is provided in the cavity and is located above the swing arm 7. The tongue of the lock tongue 6 passes through the tongue of the base 2. The hole extends forward, and a V-shaped opening is provided in the middle of the tail of the lock tongue 6 relative to the lock hole of the base. The inner side surface on the right side of the V-shaped opening of the lock tongue 6 is an arc-shaped surface, and the curvature of the arc-shaped surface is large enough to allow the paddle of the lock cylinder 4 to be unobstructed in the arc-shaped surface area when it rotates 360 degrees. The left side of the lock tongue 6 overlaps with the swing arm 7 up and down, and the middle and tail of the outer side surfaces are respectively provided with bayonet holes corresponding to the card column. A bayonet hole corresponding to the paddle of the lock cylinder 4 is provided at the tail of the inner side surface of the left side of the lock tongue 6. The lock cylinder 4 is inserted into the lock hole of the face cover and the base 2 and installed and passes through the V-shaped opening of the lock tongue 6. A guide column 6.1 is raised at the top tail end of the right side of the lock tongue 6, and a splint is superimposed on the top of the base. Strip holes are provided at the corresponding positions of the splint and the guide column 6.1. The guide column 6.1 is inserted into the strip hole so that the guide column 6.1 can guide the lock tongue to move forward and backward in a straight line; when the key is inserted into the lock cylinder and the paddle of the lock cylinder 4 is turned, the paddle can slide into or out of the inner slot on the left side of the lock tongue 6, forcing the swing arm to swing left and right and the lock tongue to move forward and backward, so that the card column switches between the two slots in the middle and tail of the outer left side of the lock tongue 6, completing the opening and closing action of the lock.
