AI Technical Summary
In the existing technology, the linkage screen lock is prone to wear and deformation during the transmission process, has high maintenance costs, and the opening and closing actions are cumbersome, making it difficult for children or the elderly to operate. In addition, the linkage mechanism requires multiple points to drive synchronously, which can lead to misalignment of the locking points or poor sealing.
It adopts a spring-loaded lock design, which realizes locking and unlocking actions through the rotational connection between the toggle component and the lock fan slide and the push-type elastic locking, simplifying the operation steps, improving the success rate and reducing the difficulty of maintenance.
It achieves simple and easy-to-understand locking and unlocking actions, is suitable for people of all ages, reduces maintenance costs and the complexity of parts replacement, improves the success rate of locking and unlocking, and has a simple structure that is easy to clean and maintain.

Abstract
Claims
1. A spring-loaded lock for opening a protective screen window sash, comprising a spring-loaded lock body, a mounting cavity, and a lock sash slide block, wherein the spring-loaded lock body includes an outer frame, the mounting cavity is provided inside the outer frame, and the lock sash slide block is slidably disposed on the outer side of the window inside the mounting cavity; characterized in that, The mounting cavity extends through the middle of the outer frame along the inner and outer sides of the window. The lock fan slide slides upward along the upper middle part of the mounting cavity, and the bottom inner side of the lock fan slide abuts against the top middle part of the unlocking assembly. The pop-up lock also includes a toggle assembly and an unlocking assembly. The toggle part of the toggle assembly is engaged with the inner side of the upper window of the lock fan slide. The unlocking assembly can be slidably disposed on the inner side of the bottom window of the mounting cavity. The locking part of the toggle assembly is tilted to the lower right and pressed against the unlocking assembly, thereby locking it on the top left side of the unlocking assembly to achieve the locking action.
2. A bouncing lock for opening a protective screen window according to claim 1, wherein The pop-up lock body also includes an upper fixing block, a lower fixing block, a toggle groove, a lock fan groove, and an unlocking groove. The upper fixing block is fixedly disposed on the upper part of the mounting cavity of the outer frame, and the lower fixing block is fixedly disposed on the lower part of the mounting cavity of the outer frame. The toggle groove is horizontally disposed on the middle part of the inner side of the window of the outer frame, the lock fan groove is horizontally disposed on the middle part of the outer side of the window of the outer frame, and the unlocking groove is horizontally disposed on the lower middle part of the outer frame.
3. A bouncing lock for opening a protective screen window according to claim 2, wherein The locking fan slide includes a locking fan elastic element, a locking fan slider, and a fan-window connecting block. The upper fixing block, the locking fan elastic element, and the locking fan slider are connected sequentially from top to bottom within the mounting cavity. The locking fan slider is fixedly connected to the inner side of the fan-window connecting block, and a screen fan is connected to the outer side of the fan-window connecting block. The locking fan slider moves upward and compresses the locking fan elastic element, causing the fan-window connecting block to lock the screen fan.
4. A bouncing lock for opening a protective screen window according to claim 2, wherein The unlocking assembly includes an unlocking elastic element, an unlocking slider, an unlocking groove, and an unlocking drive block. The lower fixing block, the unlocking elastic element, and the unlocking slider are connected sequentially from bottom to top within the mounting cavity. The unlocking drive block is fixedly disposed inside the window of the unlocking slider and protrudes into the unlocking groove. The unlocking drive block slides downward to abut against the bottom end of the unlocking groove, and the unlocking slider compresses the unlocking elastic element downward, thereby causing the top of the unlocking slider to disengage from the bottom of the actuating assembly to achieve unlocking.
5. The bouncing lock for opening the protective screen window shutter according to claim 3, wherein The actuating assembly includes an actuating body, an actuating part, and an actuating slot. The actuating part is located on the top of the actuating body. The actuating part is Y-shaped. The top left side of the lock fan slider is provided with an actuating slot with a U-shaped cross section. The right side of the Y-shaped actuating part is engaged in the actuating slot. The actuating part of the actuating assembly moves the lock fan slider upward, and the locking part tilts downward and engages with the top of the unlocking assembly for locking.
6. A bouncing lock for opening a guard screen window sash as claimed in claim 5, characterized in that, The actuating assembly further includes a locking part, which is disposed at the bottom of the actuating body. The bottom of the locking part is provided with an inverted U-shaped locking groove, and a square locking block is provided on the inner side of the window at the top of the unlocking slider of the unlocking assembly. The locking part of the actuating assembly is pressed into the actuating groove, driving the unlocking slider to compress the unlocking elastic element downward. The locking block of the unlocking slider is engaged with the locking groove of the locking part, thereby achieving locking.
7. The bouncing lock for opening the guard bar screen window according to claim 3, wherein The lock fan elastic element includes a guide rod and a spring sleeved on the outer ring surface of the guide rod. The unlocking elastic element includes a guide rod and a spring sleeved on the outer ring surface of the guide rod. The guide rod can extend and retract in the longitudinal direction.
