Description

Technical Field

[0001] The utility model relates to door and window hardware, in particular to a door lock with an independent double-single-tongue lock body. Background Art

[0002] Door locks are common anti-theft devices. Existing door locks include a lock body, a square lock tongue, an oblique lock tongue and a handle. The oblique lock tongue is used to lock the door when closing it, and the square lock tongue is used to lock it. A linkage mechanism is provided between the square lock tongue and the oblique lock tongue, and the lock is unlocked and locked by turning the handle or the lock cylinder. Existing door locks have the following technical defects: 1. The linkage mechanism structure is relatively complex and the processing cost is high. 2. Since the square lock tongue and the oblique lock tongue need to be linked and installed in the same lock body, the lock body is large in size and occupies a large space during installation, especially for wooden doors. A larger installation hole needs to be opened, which makes the strength of the wooden door low at the location where the door lock is installed, and the door lock is not firmly installed between the wooden door. Utility Model Content

[0003] In order to solve the problems of high processing cost, large space occupied and loose installation between door locks and wooden doors in existing door locks, the utility model provides a door lock with an independent double single-tongue lock body. The door lock with an independent double single-tongue lock body eliminates the linkage mechanism in the prior art, simplifies the door lock structure, has a simple structure, low cost, and small space occupied. When used on a wooden door, the opening is small and the installation is firm.

[0004] The technical solution of the utility model is: a door lock with independent double single-tongue lock bodies, comprising an inner door handle, an outer door handle, a locking knob and a lock core, a slanted-tongue single-tongue lock body is arranged between the inner door handle and the outer door handle, and the slanted-tongue single-tongue lock body can be unlocked by rotating the inner door handle and the outer door handle; a square-tongue single-tongue lock body is arranged between the locking knob and the lock core, and the square-tongue single-tongue lock body can be locked or unlocked by rotating the locking knob and the lock core; the slanted-tongue single-tongue lock body and the square-tongue single-tongue lock body are independently controlled.

[0005] The oblique-bolt single-bolt lock body and the square-bolt single-bolt lock body share the same door lock guide piece.

[0006] The inner door handle and the locking knob are respectively installed on the first inner lock cover and the second inner lock cover, and the outer door handle and the lock core are respectively installed on the first outer lock cover and the second outer lock cover.

[0007] Positioning blocks are provided between the first inner locking cover and the first outer locking cover and between the second inner locking cover and the second outer locking cover, and the positioning blocks are used for positioning the oblique tongue single tongue lock body and the square tongue single tongue lock body.

[0008] The utility model has the following beneficial effects: due to the adoption of the above technical scheme, when in use, the door handle inside, the door handle outside and the oblique tongue single tongue lock body are independently installed, the locking knob, the lock core and the square tongue single tongue lock body are also independently installed, the oblique tongue single tongue lock body and the square tongue single tongue lock body are independently controlled, the oblique tongue single tongue lock body is automatically locked when the door is closed, the door lock can be opened by rotating the door handle inside and the door handle outside, and the square tongue single tongue lock body can be used to lock the door by rotating the locking knob inside or rotating the lock core outside the door. The utility model cancels the linkage mechanism in the prior art, simplifies the door lock structure, has a simple structure, low cost, and occupies a small space. When used on a wooden door, two independent installation holes are drilled, and the two installation holes do not need to be connected. After the door lock is installed, the door lock installation hole of the wooden door is small, and the location still has good strength and is not easy to be damaged. The door lock is firmly installed between the wooden door. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0012] The utility model is further described below in conjunction with the accompanying drawings:

[0013] Depend on Figure 1-2As shown, a door lock with independent double single-tongue lock bodies comprises an inner door handle 1, an outer door handle 2, a locking knob 3 and a lock core 4, wherein an oblique-tongue single-tongue lock body 5 is arranged between the inner door handle 1 and the outer door handle 2, and the oblique-tongue single-tongue lock body 5 can be unlocked by rotating the inner door handle 1 and the outer door handle 2; a square-tongue single-tongue lock body 6 is arranged between the locking knob 3 and the lock core 4, and the square-tongue single-tongue lock body 6 can be locked or unlocked by rotating the locking knob 3 and the lock core 4; the oblique-tongue single-tongue lock body 5 and the square-tongue single-tongue lock body 6 are independently controlled. Due to the adoption of the above technical scheme, when in use, the inner door handle 1, the outer door handle 2 and the oblique bolt single tongue lock body 5 are independently installed, the locking knob 3, the lock core 4 and the square bolt single tongue lock body 6 are also independently installed, the oblique bolt single tongue lock body 5 and the square bolt single tongue lock body 6 are independently controlled, and the oblique bolt single tongue lock body 5 is automatically locked when the door is closed, and the door lock can be opened by rotating the inner door handle 1 and the outer door handle 2. If it is necessary to lock the door, the locking knob 3 is rotated inside the door or the lock core 4 is rotated outside the door to use the square bolt single tongue lock body 6 to lock. The utility model cancels the linkage mechanism in the prior art, simplifies the door lock structure, the oblique bolt single tongue lock body 5 and the square bolt single tongue lock body 6 are processed separately, and the structure is simple, the cost is low, and the space occupied is small. When used on a wooden door, two independent installation holes are excavated, and the two installation holes do not need to be connected. After the door lock is installed, the door lock installation position of the wooden door is small, and the position still has good strength and is not easy to be damaged. The door lock is firmly installed between the wooden door.

[0014] The oblique bolt single-tongue lock body 5 and the square bolt single-tongue lock body 6 share the same door lock guide piece 12. The same door lock guide piece 12 is used to facilitate the positioning of the oblique bolt single-tongue lock body 5 and the square bolt single-tongue lock body 6, and is easy to install.

[0015] The inner door handle 1 and the locking knob 3 are respectively mounted on the first inner lock cover 7 and the second inner lock cover 8, and the outer door handle 1 and the lock core 3 are respectively mounted on the first outer lock cover 9 and the second outer lock cover 10. The first inner lock cover 7 and the first outer lock cover 9 and the second inner lock cover 8 and the second outer lock cover 10 are respectively fixed on both sides of the door body.

[0016] Positioning blocks 11 are provided between the first inner lock cover 7 and the first outer lock cover 9 and between the second inner lock cover 8 and the second outer lock cover 10. The positioning blocks 11 are used to position the oblique bolt single-tongue lock body 5 and the square bolt single-tongue lock body 6. The positioning blocks 11 can prevent the oblique bolt single-tongue lock body 5 and the square bolt single-tongue lock body 6 from moving.
