[0032] Embodiment 1
[0033] This embodiment provides a screen window pocket lock 100, as Figure 1-8 shown, including a lock frame that can accommodate the protruding handle of the glass window and a lock body for fixing the screen window to the window main structure; the lock body is arranged at the end of the lock frame, and in this embodiment, it is arranged at the lower part of the lock frame (such as an exploded Figure 2As shown in the figure. The lock body includes a locking tongue 1 for fixing the screen window to the glass window, a lock core 2 for driving the locking tongue 1 to reciprocate in the width direction of the lock frame, and a fixing bracket 3 for fixing the lock core 2. The fixing bracket 3 is provided with a first cavity 4 for accommodating the lock core 2 and a locking tongue hole 5 allowing the locking tongue 1 to pass through and move in the width direction of the lock frame therein. The lock core 2 reciprocates in the first cavity 4 to drive the locking tongue 1 to pass through the locking tongue hole 5 and reciprocate in the width direction of the lock frame to realize the opening and closing of the screen window; the lock core 2 further includes a handle 6 for conveniently driving the lock core 2. One end of the handle 6 is fixedly connected to the lock core 2, and the other end passes through the lock frame for convenient user operation.
[0034] In order to improve the industrial manufacturing efficiency of the lock core 2, the lock core 2 is provided with a locking tongue fixing hole 7 which is in interference fit with the locking tongue 1. When assembling the lock core 2, the locking tongue 1 is inserted into the locking tongue fixing hole 7 to realize the assembly of the lock core 2 and the locking tongue 1. By manufacturing the locking tongue 1 and the lock core 2 separately instead of integrally, the manufacturing process difficulty of the lock core 2 can be effectively reduced, and at the same time, the production efficiency of the lock core 2 and the locking tongue 1 can be improved.
[0035] When the screen window is closed, it generally slides from left to right; but in some special scenarios, the screen window may need to slide from right to left when closed. To meet the locking requirements of the screen window pocket lock in the above two scenarios, in this embodiment, the locking tongue fixing hole 7 includes a left locking tongue fixing hole 71 and a right locking tongue fixing hole 72, which are respectively arranged at the left end and the right end of the lock core 2; when locking the screen window sliding from left to right, the locking tongue 1 is installed in the right locking tongue fixing hole 72, and when locking the screen window sliding from right to left, the locking tongue 1 is installed in the left locking tongue hole 71.
[0036] When the glass window is in the closed state and the screen window is also in the closed state, the protrusion of the locking tongue causes the screen window box and the glass window not to be in the closed state at the same time. To solve the above problem, the fixing bracket 3 of the screen window pocket lock is provided with a first flipping groove 31 for the handle 6 to rotate in the radial direction of the lock core and a second flipping groove 32 for the locking tongue 1 to rotate in the radial direction of the lock core. The handle 6 flips in the radial direction of the lock core to drive the lock core 2 and the locking tongue 1 to rotate, and the locking tongue 1 enters the second flipping groove 32 to realize the hiding of the locking tongue 1.
[0037] As a frequently used driving part, the handle 6 may become loose after long-term use. To avoid the above problem, in this embodiment, the handle 6 and the lock core 2 are preferably designed as an integral body to improve the firmness of the connection between the handle 6 and the lock core 2 and extend the service life of the handle 6.
[0038] To further enhance the user experience of the screen window pocket lock, the screen window pocket lock is also equipped with a locking device to prevent children from casually opening the screen window pocket lock when playing. The locking device includes a locking member that prevents the reciprocating movement of the locking lock core 2 and a locking hole 11 provided on the lock core 2 that cooperates with the locking member to lock the position of the lock core 2. The locking member includes a locking column 8 and a driving disk 9 that drives the locking column 8 to move up and down. A groove 10 that cooperates with the locking column 8 is provided on the driving disk 9. One end ( Figure 2 the lower end) of the locking column 8 cooperates with the locking hole 11 to fix the lock core 2, and the other end is rotatably connected to the driving disk 9.
[0039] When the locking device locks the lock core 2, the lock core 2 is in a non-movable state. The driving disk 9 drives the locking column 8 into the locking hole 11 on the lock core 2 to fix the lock core 2. When the locking device is in the unlocked state, the lock core 2 can reciprocate along the first cavity 4, and the driving disk 9 drives the locking column 8 away from the locking hole 11 on the lock core 2 to unlock the lock core 2.
[0040] To enhance the stability of the rotation of the driving disk 9, a screw hole 12 is provided on the fixing frame 3, and a protrusion 13 is provided at the lower end of the driving disk 9. The screw hole 12 cooperates with the protrusion 13 to stabilize the driving disk 9.
[0041] To reduce the resistance of the rotating driving disk 9 to drive the locking column 8 and enhance the user experience, the end face ( Figure 2 the upper end face of the driving disk in it) of the driving disk 9 that contacts the locking column 8 is provided with a slideway for guiding the locking column 8 into the groove 10. Preferably, the cross-section of the slideway is arc-shaped (not shown in the figure).
[0042] To further enhance the flexibility of the locking column 8 entering and exiting the locking hole 11, the locking device further includes a compression spring (not shown in the figure) that drives the locking column 8 into the unlocked state. A convex ring 14 is provided in the middle part of the locking column 8. The diameter of the convex ring 14 is larger than the diameter of the locking column 8. The compression spring is sleeved on the side ( Figure 6 the lower side) of the convex ring 14 close to the lock core 2.
[0043] The lock frame includes a housing 15 that houses the cover plate 16, a mop 17 that is fixedly connected to the cover plate 16 and pushes and pulls the cover plate 16, and a back plate 18 that fixes the housing 15 to the screen window frame; a first channel 19 for housing the handle 6 and a second channel 20 for housing the driving disk 9 are provided on the housing 15. The first channel 19 is provided at the end ( Figure 2 the lower end) of the housing 15, and the second channel 20 is provided on the same side as the first channel 19 ( Figure 2 the lower end of the second channel 20 in it).
[0044] Embodiment 2
[0045] As Figure 9As shown in the figure, an embodiment provides a window screen 200, which includes a window screen main structure 201, a window screen 202 externally connected to the window screen main structure 201 around the perimeter, and a screen window pocket lock 100 installed on the window screen main structure 201. For the specific structure and function of the screen window pocket lock 100, please refer to Embodiment 1, and they will not be elaborated in this embodiment.
[0046] The foregoing are only preferred embodiments of the present utility model and are not intended to limit the present utility model.
