In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0038] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0039] like Figures 1 to 8 As shown, the safety push-pull lock of the utility model is applied to the push-pull lock of doors and windows. It can be used normally on the indoor side and has an anti-pry function on the outdoor side, which is highly safe.
[0040] The safety push-pull lock of the utility model specifically comprises a main body shell 1, a main body switch 2, a main body bottom plate 3, a lock tongue 4 and a limit assembly 5; the main body switch 2 is connected to the main body shell 1, and the main body bottom plate 3 is arranged on the side of the main body switch 2 away from the main body shell 1; the lock tongue 4 is movably connected to the main body bottom plate 3, the lock tongue 4 is connected to the main body switch 2, the limit assembly 5 is fixed on the main body bottom plate 3, and the limit assembly 5 is arranged on the side of the main body switch 2.
[0041] The main switch 2 has a first position and a second position relative to the limit assembly 5: Figure 5 As shown, at this time, the main switch 2 is located in the first position, the limit assembly 5 is extended, and the limit assembly 5 abuts against the lock tongue 4, thereby limiting the movement of the lock tongue 4; Figure 6 As shown, at this time, the main switch 2 is located in the second position, the main switch 2 squeezes the limit assembly 5, so that the limit assembly 5 is retracted, the limit assembly 5 is separated from the lock tongue 4, and the main switch 2 moves a certain distance, which can drive the lock tongue 4 to move, thereby realizing the unlocking of the push-pull lock.
[0042] In a specific application, the safety push-pull lock of the utility model is installed on doors and windows. When located on the outdoor side, the lock tongue 4 cannot be pried to drive the main switch 2 to move, and the main switch 2 is always located in the first position. The limit assembly 5 can limit the movement of the lock tongue 4, so the lock tongue 4 cannot be pried on the outdoor side to achieve unlocking, which serves the purpose of anti-prying and anti-theft, and ensures the safety of people and property. When located on the indoor side, the main switch 2 is moved from the first position to the second position, and the limit assembly 5 is squeezed by the main switch 2 and cannot limit the movement of the lock tongue 4. Further toggling the main switch 2 can drive the lock tongue 4 to move, and the doors and windows are unlocked normally.
[0043] In some embodiments, two limit assemblies 5 are provided, and the limit assemblies 5 are respectively provided on both sides of the main switch 2; the limit assemblies 5 specifically include a top block 51 and a first elastic element 52, one end of the first elastic element 52 is fixedly connected to the top block 51, and the other end of the first elastic element 52 is fixedly connected to the main bottom plate 3. Figure 5 As shown, when the main switch 2 is in the first position, the main switch 2 does not squeeze the limit assembly 5, the first elastic element 52 drives the top block 51 to extend, the top block 51 abuts against the lock tongue 4, and the top block 51 limits the movement of the lock tongue 4 to achieve anti-pry. Figure 6 As shown, when the main switch 2 is in the second position, the main switch 2 squeezes the limit assembly 5, compresses the first elastic element 52, and the top block 51 is recovered and separated from the lock tongue 4. The lock tongue 4 can pass between the two limit assemblies 5, and the main switch 2 can drive the lock tongue 4 to move, thereby achieving unlocking.
[0044] In some embodiments, the main switch 2 is provided with a connecting rod 21, which includes a first connecting portion 21a, an inclined portion 21b and a second connecting portion 21c connected in sequence, and the width of the inclined portion 21b toward the first connecting portion 21a is greater than the width of the inclined portion 21b toward the second connecting portion 21c. Figure 5 As shown, when the main switch 2 is in the first position, the top block 51 abuts against the side of the second connection portion 21c. Since the width of the second connection portion 21c is smaller than the width of the first connection portion 21a, the distance between the two top blocks 51 is smaller than the width of the lock tongue 4. Therefore, the lock tongue 4 cannot pass through and is restricted from moving. Figure 6 As shown, when the main switch 2 is located in the second position, the top block 51 abuts against the side of the first connecting portion 21a. Since the width of the second connecting portion 21c is smaller than the width of the first connecting portion 21a, the distance between the two top blocks 51 is greater than the width of the locking tongue 4, and the locking tongue 4 can pass between the two top blocks 51.
