Technical Field

[0001] This utility model relates to the field of door lock latches, and in particular to a door lock latch. Background Technology

[0002] A door lock latch generally consists of a moving part and a fixed part. The moving part is usually connected to the door, while the fixed part is installed on the door frame. The door is opened and closed by the engagement and disengagement of the moving and fixed parts.

[0003] A search revealed a directionally adjustable movable door latch, disclosed in Chinese Patent No. CN 220203666 U. This latch includes a first fixed plate, a second fixed plate on the right side of the first fixed plate, shock-absorbing rods on the surfaces of both the first and second fixed plates, a buffer block on the outer side of the shock-absorbing rods, a mounting hole on the surface of the first fixed plate, a third fixed plate on the outer side of the first fixed plate, and a fourth fixed plate on the outer side of the first fixed plate. A locking screw is installed inside the mounting hole. This directionally adjustable movable door latch, with its shock-absorbing rods, buffer block one, and buffer block two, features a simple overall structure, facilitating user operation. Furthermore, in the event of a collision, the shock-absorbing rods and buffer block one protect the first and second fixed plates, while the buffer block two protects the first and second handles, thus extending the device's lifespan.

[0004] However, the aforementioned adjustable door latch is prone to being pried open by a thin sheet from the outside through the door gap during use, forcing the fixed plate three to separate from the right-angle latch, thus posing a certain safety hazard.

[0005] Therefore, it is essential to invent a door lock latch. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a door lock latch, including a raised latch and a fixing base. The raised latch has an insertion hole. A pin is slidably installed on the fixing base, and the pin is plugged into the insertion hole.

[0007] The pin includes a front cover plate, a rear cover plate, and a balance plate. The balance plate is slidably installed between the front cover plate and the rear cover plate, and the rear cover plate is detachably fixed to the front cover plate.

[0008] The front cover plate has an open mounting cavity on one side, and the rear cover plate is sealed and installed at the open part of the mounting cavity. The front cover plate has button holes and limiting holes evenly distributed through it. The button holes are located at the center of the mounting cavity, and the balance plate is slidably installed in the mounting cavity.

[0009] One side of the balance plate is fixedly connected to the rear cover plate by at least one compression spring. The other side of the balance plate is uniformly fixedly equipped with a stop block and a button. The stop block slides out from the limiting hole, and the button slides out from the button hole. After the pin is inserted into the socket, the socket is located between the stop block and the button.

[0010] After the compression spring is fully compressed, the outer surface of the stop and the button is flush with the outer surface of the front cover.

[0011] The convex locking buckle and the fixing base each have at least one through-hole.

[0012] The raised part of the embossed latch has notches on both sides corresponding to the stop block and the button.

[0013] The fixed base has a through groove, and the pin is slidably connected to the groove.

[0014] A slider is fixedly installed on the outer side of the rear cover plate, and the slider is slidably installed in the slide groove.

[0015] The slider is detachably and fixedly installed with an anti-detachment cap at one end inside the slide groove, and the anti-detachment cap is slidably installed in the slide groove.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] Example:

[0028] As attached Figure 1 To be continued Figure 4 As shown:

[0029] This utility model provides a door lock latch, including a raised latch 1 and a fixing base 5. The raised latch 1 has a hole 2. A pin is slidably installed on the fixing base 5, and the pin is plugged into the hole 2.

[0030] In this embodiment, the pin includes a front cover plate 7, a rear cover plate 8, and a balance plate 9. The balance plate 9 is slidably installed between the front cover plate 7 and the rear cover plate 8. The rear cover plate 8 is detachably fixedly connected to the front cover plate 7 for later disassembly and maintenance.

[0031] In this embodiment, the front cover plate 7 has an open mounting cavity 10 on one side to provide retraction space for the stop block 15 and the button 16. The rear cover plate 8 is sealed and installed at the open part of the mounting cavity 10. The front cover plate 7 has a button hole 11 and a limiting hole 12 evenly through it so that the stop block 15 and the button 16 are hidden in the mounting cavity 10 and can also be exposed from the mounting cavity 10. The button hole 11 is located at the center of the mounting cavity 10. The balance plate 9 is slidably installed in the mounting cavity 10.

[0032] In this embodiment, one side of the balance plate 9 is fixedly connected to the rear cover plate 8 by at least one compression spring 18 so that the stop block 15 and the button 16 can automatically rebound. The other side of the balance plate 9 is uniformly fixedly equipped with the stop block 15 and the button 16 so that by pressing the button 16, the button 16 and the stop block 15 can be hidden in the mounting cavity 10 at the same time. The stop block 15 slides out from the limiting hole 12, and the button 16 slides out from the button hole 11. After the pin is inserted into the socket 2, the socket 2 is positioned between the stop block 15 and the button 16, which can prevent the pin from separating from the socket 2.

[0033] Button 16 is located at the center of balance plate 9 so that when button 16 is pressed, stop block 15 is activated simultaneously.

[0034] In this embodiment, after the compression spring 18 is fully compressed, the outer surfaces of the stop block 15 and the button 16 are flush with the outer surface of the front cover plate 7, so that the pin can be inserted into the socket 2 and removed from the socket 2.

[0035] In this embodiment, each of the convex locking buckle 1 and the fixing base 5 has at least one through-hole 4 so as to cooperate with the fixing component to install the convex locking buckle 1 and the fixing base 5 at the required position on the door.

[0036] In this embodiment, notches 3 corresponding to the stop block 15 and the button 16 are respectively opened on both sides of the protrusion of the convex character lock 1 so that after the pin is locked with the convex character lock 1, it can better fit together with the stop block 15 and the button 16.

[0037] In this embodiment, a sliding groove 6 is provided through the fixed base 5, and the pin is slidably connected to the sliding groove 6; a slider 13 is fixedly installed on the outer side of the rear cover plate 8, and the slider 13 is slidably installed in the sliding groove 6 so as to limit the pin and ensure the stability of the pin during movement.

[0038] In this embodiment, the end of the slider 13 located inside the slide groove 6 is detachably and fixedly equipped with an anti-detachment cap 14. The anti-detachment cap 14 is slidably installed in the slide groove 6 to prevent the pin from accidentally separating from the fixed seat 5, and at the same time facilitates the disassembly and maintenance of the pin in the future.

[0039] In this embodiment, a handle 17 is fixedly installed on the front of the front cover 7. The handle 17 is located on one side of the button 16 so as to provide a grip point for the operator when pressing the button 16.

[0040] Specifically, when locking is required, press button 16 with your thumb and hold handle 17 with the other four fingers. By pressing button 16, the stop 15 is hidden in the mounting cavity 10. The pin can then slide to one side of the convex locking buckle 1, inserting the pin into the socket 2 until the stop 15 protrudes from the socket 2. At this point, release button 16. Under the action of compression spring 18, button 16 and stop 15 automatically rebound, so that button 16 and stop 15 are on both sides of the socket 2, thereby locking the pin and the socket 2 together.

[0041] When unlocking is required, press button 16 to conceal the stop 15 in the mounting cavity 10, and slide the pin in the opposite direction to move the pin out of the socket 2 until the stop 15 protrudes from the socket 2. At this point, release button 16, and under the action of compression spring 18, button 16 and stop 15 will automatically spring back, so that button 16 and stop 15 are on the same side of the socket 2, thereby separating the pin from the socket 2. Because button 16 and stop 15 automatically spring back, accidental locking can be prevented after opening, making it safer and more reliable.

[0042] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
