Description

Technical Field

[0001] The utility model relates to the technical field of screen window locks, in particular to a double-locking screen window lock. Background Art

[0002] As people's quality of life improves, the requirements for windows are also increasing. In addition to windproof window sashes, in order to prevent outdoor mosquitoes, flies and other insects from entering the room when the window sash is open, a screen is generally installed on the window sash. In order to prevent the screen from being blown open by the wind and to facilitate the operation and control of the screen, the screen is fixed to the window frame through a screen lock. The existing screen lock can be opened by simple operations such as pressing and toggling. If a child climbs onto the windowsill and opens the screen at will, it will inevitably cause the child to climb out of the window. Therefore, a screen lock that can prevent children from operating it by mistake is needed.

[0003] In order to solve the above problems, a utility model patent with authorization announcement number CN220539441U discloses a screen window lock, which controls the extension and retraction of the lock pin through a switch and a password component to prevent the extension and retraction of the lock pin caused by accidental touching of the switch. The locking groove of the turntable and the first abutment part of the switch cooperate to make unlocking and locking the switch more convenient. You only need to rotate the turntable to align the locking groove with the direction of the first abutment part, and extend the first abutment part into the locking groove to unlock it. It has good stability and is not easy to disengage.

[0004] However, the device is only provided with one lock disk, and the number of passwords is relatively small. After multiple attempts, a child may still successfully unlock the lock and open the screen window. The safety performance is limited and cannot well meet the use requirements. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example: See Figures 1 to 6 A double locking screen lock comprises: a base 2, a lock shell 1, a lock core slide 4, a toggle groove 12 is provided at the upper end of the lock shell 1, a toggle block 41 is installed at the upper end of the lock core slide 4, a wedge block 42 is also installed on the lock core slide 4, the toggle block 41 is slidably installed in the toggle groove 12, a base 2 is also installed at the lower end of the lock shell 1, a pin sleeve 21 is installed on the base 2, a locking pin 5 is slidably inserted in the pin sleeve 21, and a pair of guide seats 23 are also installed at the upper end of the base 2 corresponding to the pin sleeve 22. A conical protrusion 51 is also installed on the upper end of the locking pin 5, and a return spring 52 is sleeved on the locking pin 5. The two ends of the return spring 52 are respectively in contact with the pin sleeve 21 and the corresponding side of the conical protrusion 51; the locking component is arranged in the lock housing 1, and is used to position the lock cylinder slide 4 on the locking pin 5; the locking component is arranged in the lock housing 1, and is used to fix the lock cylinder slide 4. A pair of limit seats 22 are also installed on the upper end of the base 2, and a strip groove is opened at the lower end of the lock cylinder slide 4, and the limit seat 22 extends into the strip groove.

[0025] In this embodiment, the base is embedded in the screen window frame on one side. First, the lock core slide 4 is positioned through the locking assembly so that it presses the locking pin 5, so that the end of the locking pin 5 extends out of the pin sleeve 21 and is inserted into the frame of the screen window on the other side, thereby completing the preliminary locking of the screen window. Subsequently, the lock core slide 4 is fixed by the locking assembly to prevent it from moving, which can further prevent the locking pin 5 from resetting, thereby improving the locking effect, further reducing the possibility of children opening the screen window, and improving the safety of the device.

[0026] In this embodiment, the locking assembly includes a code dial 3 rotatably mounted in the lock housing 1, a locking slot 31 is provided at the lower end of the code dial 3, a locking strip 44 is extended at the position of the lock core slide 4 corresponding to the locking slot 31, a code window 11 is provided at the upper end of the lock housing 1 corresponding to the code dial 3, and a rotation notch is provided at the side of the lock housing 1 corresponding to the position of the code dial 3. When the decoded number is rotated to the position of the code window 11, the locking slot 31 is parallel to the locking strip 44, and the locking strip 44 is inserted into the locking slot 31 to complete the unlocking work.

[0027] As a further solution, the lock housing 1 is further provided with a rotation groove 13, the locking assembly comprises a rotation sleeve 61 rotatably mounted in the rotation groove 13, a locking seat 6 is extended from the lower end of the rotation sleeve 61, a locking slider 62 is fixed to the side of the locking seat 6 close to the wedge block 42, a locking groove 43 is provided at the corresponding position of the upper end of the wedge block 42, in this embodiment, the locking slider 62 is L-shaped, the locking groove 43 is arc-shaped, and a limiting groove 14 is provided at the position corresponding to the locking slider 62 in the lock housing 1. A key slot is provided in the rotation sleeve 61, and the rotation sleeve 61 can be driven to rotate by a key.

[0028] The working principle of the utility model is as follows: when closing the lock, first, the lock cylinder slide 4 is pulled to move by the toggle block 41, so that the locking strip 44 at the end of the lock cylinder slide 4 is pulled out from the locking slot 31 at the lower end of the code dial 3. At this time, under the squeezing action of the wedge block 42, the end of the locking pin 5 passes through the pin sleeve 21 and is inserted into the screen window frame on the other side. Then, the code dial 3 is rotated, so that the locking slot 31 and the locking strip 44 are staggered. At this time, the locking strip 44 conflicts with the code dial 3 to prevent the lock cylinder slide 4 from being reset. The lock core slide 4 is in the position, so that the lock core slide 4 presses the locking pin 5, thereby completing the preliminary locking work. At this time, the wedge block 42 at the end of the lock core slide 4 extends partially under the lock seat, and then the key is inserted into the rotating sleeve 61, and then the rotating sleeve 61 is rotated to drive the lock seat 6 to rotate, and then the locking slider 62 is inserted into the locking groove 43, and the lock core slide 4 can be further fixed, thereby completing double locking, further increasing the difficulty of children unlocking, improving the safety of the device, and being able to better meet the use needs.
