Technical Field

[0001] This utility model belongs to the field of screen window lock technology, specifically relating to a screen window lock with a raised surface. Background Technology

[0002] Screen locks are important small accessories for home security. They can prevent insects from entering the room and provide a certain degree of anti-theft function. For families with children or pets, they can also prevent them from accidentally opening the window. Therefore, screen locks are indispensable for screens. In current technology, screen locks are generally opened or closed by pushing up and down the push bar on the screen lock. However, the lack of a corresponding pushing mechanism after the screen lock is opened makes it difficult for users to open the screen. Some screen locks have a relatively flat surface, resulting in low friction, making it difficult for users to quickly open or close the screen. These shortcomings in use require improvement.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1:

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, a full-surface raised screen lock includes a lock body 1, a lifting block 2 inside the lock body 1, a steel plate 3 inside the lock body 1, a switch 4 inside the lock body 1, a first compression spring 5 fixedly connected inside the lock body 1, a stop block 16 inside the switch 4, with one side of the stop block 16 contacting one end of the first compression spring 5, a locking pin 6 fixedly connected to the middle of the bottom of the lifting block 2, two locking grooves 7 inside the locking pin 6, and three slots 14 inside the steel plate 3. The surface of the connecting post 6 penetrates the interior of the slot 14. The two sides of the bottom of the lifting block 2 are fixedly connected to the second compression spring 17, and the surface of the second compression spring 17 penetrates the interior of the slot 14. The bottom of the switch 4 is fixedly connected to one side of the ring block 15. The steel sheet 3 has a circular groove 18 inside, and the surface of the ring block 15 penetrates the interior of the circular groove 18. The bottom of the lock body 1 is fixedly connected to the bottom plate 19. The bottom plate 19 has a blocking groove 20 inside, and the surface of the locking post 6 penetrates the interior of the blocking groove 20. The steel plate 3 allows the slot 14 to be opened, enabling the surfaces of the locking post 6 and the second compression spring 17 to penetrate its interior. The surface of the locking post 6 penetrates the middle slot 14, while the surface of the second compression spring 17 penetrates the slots 14 on both sides. After installation, the second compression spring 17 is in a compressed state. The switch 4 allows the abutment block 16 to move along with it, thus compressing the first compression spring 5. The opening of the locking groove 7 allows the switch 4 to be pulled, causing the abutment block 16 to move to the right. At this time, the steel plate 3 is pulled, thus... This causes the locking pin 6 to move upward, and the empty groove 14 inside the steel plate 3 disengages from the upper locking groove 7 inside the locking pin 6, causing the lifting block 2 to pop up. The annular block 15 is precisely locked inside the circular groove 18, allowing the switch 4 to move the steel plate 3. Through the setting of the base plate 19, the blocking groove 20 is opened, so that when the locking pin 6 moves upward, the lower locking groove 7 inside the locking pin 6 can be locked at the edge of the blocking groove 20, preventing the locking pin 6 from completely disengaging from the lock body 1 and falling down. The locking pin 6 has two locking grooves 7 inside, which are designed diagonally above and below.

[0023] Example 2:

[0024] Please see Figure 1 , Figure 4 and Figure 5 As shown, a square frame 8 is fixedly connected inside the lock body 1. A third compression spring 9 is fixedly connected to the inner side wall of the square frame 8, and a compression ball 10 is fixedly connected to one end of the third compression spring 9. The square frame 8 fixes the third compression spring 9, and the compression ball 10 is fixedly connected to the third compression spring 9.

[0025] The lock body 1 has an internal rotating actuating ring 11. Both sides of the actuating ring 11 are fixedly connected to connecting rings 12. Through the arrangement of the third compression spring 9 and the compression ball 10, the actuating ring 11 is first abutted. The actuating ring 11 has several gaps to facilitate the abutting of the compression ball 10. Only by forcefully actuating it will the compression ball 10 be squeezed, thereby compressing the third compression spring 9 and enabling the actuating ring 11 to rotate.

[0026] The connecting ring 12 has a slot 13 inside, and one side of the switch 4 passes through the slot 13. The slot 13 allows the switch 4 to be engaged when it moves to the right, at which point the lifting block 2 is raised to a certain height, making it easier for the user to open the screen window.

[0027] The working principle of this utility model is as follows: The user pre-installs the lock body 1 on the screen door. When the screen needs to be closed, the lifting block 2 is pressed down, and then the actuating ring 11 is moved. At this time, the actuating ring 11 drives the connecting ring 12 to rotate, which in turn causes the slot 13 to rotate. If the operator turns on the switch 4, the position of the switch 4 will abut against the circular surface of the connecting ring 12, making it difficult to open. At this time, the entire screen lock is in a locked state. To open it, simply rotate the actuating ring 11, so that the empty part on the actuating ring 11 compresses the compression ball 10, causing the third compression spring 9 to... Compression causes the actuating ring 11 to rotate the connecting ring 12, aligning the position of the slot 13 with the position of one side of the switch 4. When the switch 4 is turned on, one side of the switch 4 is inserted into the slot 13. The switch 4 then moves the annular block 15 to the right, opening the steel sheet 3. At this point, the empty groove 14 inside the steel sheet 3 separates from the upper slot 7 inside the locking post 6. The locking post 6 and the lifting block 2 then spring upwards to a certain height due to the reverse force of the second compression spring 17. The user can then open or close the screen window using the lifting block 2, which is quite convenient.
