Description

Technical Field

[0001] This utility model relates to the technical field of door and window accessories, and in particular to a bolt-type push-button lock. Background Technology

[0002] The main function of window screens is to prevent the intrusion of insects and animals, and they also provide some security. To facilitate disassembly, the industry has developed a detachable window screen, which mainly consists of a fixed frame, the window screen itself, and a latch. The latch is installed on the window screen. Users install the window screen using this latch, and the latch rod completes the installation of the movable window screen to the fixed frame. Pulling up the latch rod retracts it into the window screen, then placing the window screen into the fixed frame and releasing the latch rod causes it to automatically spring back into the fixed frame by an internal spring. Pulling the latch rod detaches it from the fixed frame, thus separating the fixed frame and the window screen. However, the latch rod is held in place by an internal spring. The existing screen is in a protruding state, meaning it remains plugged into the fixed frame. To disassemble the screen, one must simultaneously operate all the latches on the screen to detach them from the fixed frame. Alternatively, one must simultaneously pull up the latches on the same side of the screen to detach that side from the frame before pulling up the latches on the other side. This cumbersome operation hinders quick screen disassembly. Furthermore, the existing latches lack a safety lock function, allowing them to be pulled up freely. Since the latches are exposed on the screen frame, children may accidentally pull them out of curiosity, posing a safety hazard. Utility Model Content

[0003] The present invention provides a push-button lock to facilitate operation, enable quick installation and removal of guardrail screens, and provide a locking function to reduce safety hazards.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a push-button lock, comprising a lock housing, a push-button rod disposed within the lock housing, the push-button rod being able to slide up and down and protrude from the lock housing, a baffle disposed in the middle of the push-button rod, a first spring disposed at the bottom of the baffle abutting against the bottom of the lock housing, a limiting block disposed within the lock housing being able to slide back and forth, a second spring disposed on the side of the limiting block in the sliding direction abutting against the front side of the lock housing, and a protrusion disposed on the limiting block for abutting against the baffle, a circular hole disposed at the top of the lock housing, a button movably disposed within the circular hole, a first inclined surface and a stepped structure arranged along the length direction of the lock housing on the side of the button facing the limiting block, a second inclined surface and a flat surface arranged along the width direction of the lock housing on the side of the limiting block facing the button, the first inclined surface and the second inclined surface corresponding to and abutting against each other.

[0005] Furthermore, a base is provided at the bottom of the lock case, and through holes are provided on the top of the lock case and the base respectively. The first spring is aligned with the through holes. A positioning piece for positioning the first spring is provided on the base. Two positioning strips are provided at intervals in the middle of the base. The limiting block is slidably disposed between the two positioning strips.

[0006] Furthermore, the top of the button is provided with a cylindrical part corresponding to the circular hole, and the bottom is provided with a connecting part, and the top surface of the cylindrical part is recessed with an insertion groove.

[0007] Furthermore, markings are provided on the cylindrical portion and the surface of the lock housing.

[0008] Furthermore, the edges of the protrusions and baffles are rounded.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a pin, a limiting block, and a button on the lock housing, after the pin is pressed, it passes through the bottom of the lock housing and connects to the fixed frame. At the same time, the pin is held in place by the limiting block to prevent it from springing upward. By pressing the button, the limiting block is pushed to slide back and forth, causing the upper and lower positions of the protrusion and the baffle to be misaligned. The baffle loses the contact of the protrusion and, under the elastic force of the first spring, the pin springs up to the top of the lock housing, thus detaching from the fixed frame, allowing the guardrail screen to be freely disassembled. This structure is simple to operate and achieves the effect of quickly disassembling the guardrail screen. At the same time, the button and the limiting block are also provided with a stepped structure and a flat surface. The button can be rotated to separate the first inclined surface from the second inclined surface, changing it to a stepped structure abutting against the flat surface, thereby preventing the button from being pressed, thus achieving the locking effect and reducing security risks.

[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] As shown in the attached figure, this utility model discloses a push-button lock, including a lock housing 1. A push-button rod 2 is disposed within the lock housing 1, and the push-button rod 2 can slide up and down protrude from the lock housing 1. Referring to existing push-button lock structures, the push-button rod 2 is disposed within the lock housing 1 and can slide up and down within the lock housing 1, thereby achieving connection with the fixing frame 900. A baffle 21 is disposed in the middle of the push-button rod 2, and a first spring 5 is disposed at the bottom of the baffle 21, abutting against the bottom of the lock housing 1. A limiting block 4, which can slide back and forth, is disposed within the lock housing 1, and the limiting block 4 has a side abutting against the lock housing in the sliding direction. The second spring 6 is located on the front side of the lock housing 1, and the limiting block 4 is provided with a protrusion 41 for abutting against the baffle 21. The top of the lock housing 1 is provided with a circular hole 102, and a button 3 is movably disposed in the circular hole 102. The side of the button 3 facing the limiting block 4 is provided with a first inclined surface 31 and a stepped structure 33 arranged along the length direction of the lock housing 1. The side of the limiting block 4 facing the button is provided with a second inclined surface 42 and a flat surface 44 arranged along the width direction of the lock housing 1. The first inclined surface 31 and the second inclined surface 42 correspond to each other and abut against each other. Pressing the button 3 causes the first inclined surface 31 to move downward. The movement causes the limiting block 4 to be pushed laterally. Simultaneously, the limiting block 4 is compressed, and the upper and lower positions of the protrusion 41 and the baffle 21 are misaligned. This causes the baffle 21 to lose contact with the protrusion 41 and rise again to the top of the protruding lock housing 1 under the action of the first spring 5. In normal operation, the button 3 only contacts the second inclined surface 42 of the limiting block 4 via the first inclined surface 31; the stepped structure 33 and the flat surface 44 do not contact each other. However, when the button 3 rotates 90 degrees, the first inclined surface 31 and the second inclined surface 42 separate, and the stepped structure 33 and the flat surface 44 abut against each other. This prevents button 3 from being pressed and the limiting block 4 from being pushed, thus achieving the locking effect. It needs to be rotated 90 degrees in the opposite direction so that the first inclined surface 31 and the second inclined surface 42 of button 3 abut against each other again, and the stepped structure 33 and the flat surface 44 separate from each other, thus completing the unlocking. At this time, button 3 can be pressed and the limiting block 4 can be pushed. A guardrail screen 800 is equipped with multiple pin push locks. The multiple pin push locks are correspondingly set on the guardrail screen 800 and connected to the guardrail screen 800 through the bottom. The pin rod 2 can pass through the guardrail screen 800 from the bottom and connect to the fixed frame 900.

[0022] This utility model discloses a push-button lock. A push-button lock is provided on the lock housing 1, comprising a push-button rod 2, a limiting block 4, and a button 3. The push-button rod 2 is kept in an upward-protruding state by a first spring 5. When the push-button rod 2 is pressed down, it passes through the bottom of the lock housing 1 and connects to the fixing frame 900. Simultaneously, the limiting block 4 holds the push-button rod 2 in place, preventing it from springing upwards. Pressing the button 3 pushes the second inclined surface 42 of the limiting block 4 via the first inclined surface 31, causing the limiting block 4 to slide. This causes the protrusion 41 to be misaligned with the baffle 21. The baffle loses the contact of the protrusion 41 and, under the elastic force of the first spring 5, the push-button rod 2 springs towards the top of the lock housing 1, thus detaching from the fixing frame 900, allowing the guardrail screen 800 to be freely detached. This structure is simple to operate and achieves the effect of quick disassembly of the guardrail screen. People press the buttons 3 on the guardrail screen 800 in sequence, causing the pin 2 to pop out from the top of the lock housing 11. The pin 2 disengages from the fixed frame 900, at which point the guardrail screen 800 is separated from the fixed frame 900, and people can directly remove the guardrail screen 800. At the same time, the buttons 3 and the limiting block 4 are also provided with a stepped structure 33 and a flat surface 44. By rotating the button 3 90 degrees, the first inclined surface 31 and the second inclined surface 42 are separated. At this time, the button 3 abuts against the flat surface 44 of the limiting block 4 through the stepped structure 33, so that the button 3 cannot push the limiting block 4 to slide, and the button 3 cannot be pressed, thereby achieving the locking effect and reducing safety hazards.

[0023] In this embodiment, a base 11 is provided at the bottom of the lock housing 1, and through holes 101 are provided on the top of the lock housing 1 and the base 11 respectively. The first spring 5 is aligned with the through hole 101. A positioning piece 111 for positioning the first spring 5 is provided on the base 11. Two positioning strips 112 are spaced apart in the middle of the base 11. The limiting block 4 is slidably disposed between the two positioning strips 112, using the two positioning strips 112 to provide a sliding path for the limiting block 4, preventing the limiting block 4 from shifting during sliding. Figure 3 The fixing screws on the base 11 shown are close to the pin 2, and the wall thickness at the pin hole is increased to increase strength.

[0024] In this embodiment, the top of the button 3 is provided with a cylindrical part corresponding to the circular hole 102, and the bottom is provided with a connecting part. The top surface of the cylindrical part is recessed with an insertion groove, and the bottom of the button 3 is the connecting part, that is, the part used to connect with the limiting block 4. The cylindrical part passes through the circular hole 102 and can realize up-and-down sliding and rotational movement. By allowing people to use tools to insert into the insertion groove and rotate the button 3, the insertion groove is preferably set to hexagonal, such as... Figure 2 As shown, the cylindrical part and the lock housing 1 are respectively provided with markings. One marking is provided on the top surface of the cylindrical part, and the other marking is provided on the lock housing 1 between the button 3 and the pin 2, so that people can know the direction of the button 3 to lock. When the button 3 is rotated until the marking on it is aligned with the marking on the lock housing 1, it means that the locking is completed.

[0025] In this embodiment, the edges of the protrusion 41 and the baffle 21 are rounded. It should be noted that after the pin 2 is pressed down, the baffle 21 needs to push open the protrusion 41, so that the limiting block 4 moves laterally and compresses the second spring 6. After the baffle 21 slides down to the bottom of the protrusion 41, the protrusion 41 loses its pushing force and returns to its original position under the elastic force of the second spring 6, thus blocking the top of the baffle 21 and preventing the pin 2 from sliding up. The rounded treatment makes it easier for the baffle 21 to push the protrusion 41 to move laterally.

[0026] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
