Description

Technical Field

[0001] The invention belongs to the technical field of locks and relates to a door lock panel, in particular to a small-volume door lock panel. Background Art

[0002] The door lock body is usually located inside the door panel, and a door lock panel is set on the inner and outer surfaces of the door panel. The door lock panel is fixed to the door lock mounting base to make the door lock more beautiful. For personal privacy and safety, a safety device is usually set on the door lock to control the movement of the door lock through the safety pin to achieve one-way control of the door lock movement.

[0003] Traditional channel lock panels are fixed to the door lock or door panel by setting fixing bolts that are coaxial with the square axis. The exposed fixing bolts make the door lock panel larger. Since the fixing bolts are exposed, the clamping part of the installation tool is shallow and difficult to operate. The fixing bolts are coaxial with the square axis. Therefore, when disassembling the door lock, it is necessary to remove the door handle first, and then use the matching tools for docking and disassembly, which makes it difficult to disassemble. Summary of the Invention

[0004] The purpose of the present invention is to address the above-mentioned problems existing in the prior art and to provide a door lock panel which is small in size and easy to assemble and disassemble.

[0005] The objectives of the present invention can be achieved through the following technical solutions: A small-volume door lock panel, characterized in that it includes a panel mounting seat with a mounting cavity on one side and a torque head arranged in the mounting cavity, a fixing piece is arranged in the mounting cavity, a mounting hole for the mounting tool to be clamped is opened in the fixing piece, and a connecting part for connecting and fixing is provided at one end of the fixing piece, a safety hole coaxial with and connected to the mounting hole is opened on the panel mounting seat, a reset spring for connecting is provided between the mounting cavity and the torque head, the ends of the reset springs are all clamped in the mounting cavity, a control part of the reset spring is provided on the torque head, and a fixed baffle for limiting the torque head, the reset spring and the fixing piece is provided on the mounting cavity.

[0006] In the above-mentioned small-volume door lock panel, a rotation portion for guiding the rotation of the torque head is provided in the installation cavity, and a plurality of spring limiting portions are protruding from the rotation portion. Both ends of the reset spring are provided with clamping ends clamped on the spring limiting portions. The torque head is provided with a plurality of control portions for squeezing the clamping ends, and a square hole for clamping the door lock square core is opened in the center of the torque head.

[0007] In the above-mentioned small-volume door lock panel, a compression spring is provided between the fixing member and the panel mounting seat.

[0008] In the above-mentioned small-volume door lock panel, the connecting portion is a connecting thread.

[0009] In the above-mentioned small-volume door lock panel, a snap-in hole for installing the mounting piece is provided on the fixed blocking piece.

[0010] In the above-mentioned small-volume door lock panel, the installation cavity is provided with a plurality of locking screws for fixing the installation seat.

[0011] In the above-mentioned small-volume door lock panel, the mounting hole is a hexagonal hole.

[0012] Compared with the existing technology, this new door lock panel reduces the protruding part on the panel by setting a fixing piece connected to the safety hole in the installation cavity, and fixes the reset spring, torque head and fixing piece in the cavity through a fixed baffle to keep the panel as a whole, making the disassembly and assembly of the panel easier. The hexagonal mounting hole can be used for the installation of the safety pin, and no special tools are required during disassembly and assembly, making disassembly and assembly easier.

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0019] like Figure 1 、 2As shown in Figures 3 and 4, the small-volume door lock panel includes a panel mounting seat 8 with a mounting cavity 1 on one side and a torque head 6 arranged in the mounting cavity 1. A fixing member 16 is provided in the mounting cavity 1, and a mounting hole 4 for the mounting tool to be clamped is provided in the fixing member 16. One end of the fixing member 16 is provided with a connecting portion for connection and fixing. A safety hole 10 is provided on the panel mounting seat 8, which is coaxial with and connected to the mounting hole 4. A reset spring 11 is provided between the mounting cavity 1 and the torque head 6 for connection. The ends of the reset spring 11 are clamped in the mounting cavity 1. The torque head 6 is provided with a reset spring. The control part 15 of the spring 11 is provided, and the mounting cavity 1 is provided with a limited torque head 6, a return spring 11 and a fixed baffle 7 of the fixing member 16. During assembly, the torque head 6, the return spring 11 and the mounting member are first installed in the mounting cavity 1 in sequence, and then these components are fixed as a whole by the fixed baffle 7, which reduces the volume of the panel and makes the disassembly and assembly of the door lock panel easier. The safety hole 10 coaxially arranged with the mounting hole 4 makes the installation of the safety latch easier. When disassembly is required, the safety latch is removed, and the door lock panel is disengaged from the door lock by rotating the fixing member 16 and disassembled.

[0020] Preferably, a rotation portion 9 for guiding the rotation of the torque head 6 is provided in the installation cavity 1, and a plurality of spring limiting portions 14 are protruding from the rotation portion 9, and a clamping end 13 is provided at both ends of the reset spring 11 to be clamped on the spring limiting portion 14, and a plurality of control portions 15 for squeezing the clamping ends 13 are provided on the torque head 6, and a square hole 3 for clamping the door lock square core is provided in the center of the torque head. The rotating door handle is compressed by the spring and controls the door lock to open. After the door handle is released, the lower door handle is reset under the action of the spring.

[0021] Preferably, a compression spring 12 is provided between the fixing member 16 and the panel mounting seat 8. The compression spring 12 makes the fixing member 16 close to the fixing baffle 7, preventing the fixing member 16 from being displaced during installation, making the installation of the fixing member 16 easier.

[0022] Preferably, the connecting portion is a connecting thread 5, through which the door lock panel can be fixed to the door panel, or fixed to the door lock safety through the connecting thread 5, so that the mounting hole 4 and the safety remain coaxial.

[0023] Preferably, the mounting cavity 1 is provided with a plurality of locking screws 2 for fixing the mounting seat.

[0024] Preferably, a snap-in hole 17 for mounting the mounting member 4 is provided on the fixed baffle 7 .

[0025] Preferably, the mounting hole 4 is a hexagonal hole.

[0026] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.

[0027] Although this document frequently uses terms such as mounting cavity 1, locking screw 2, square hole 3, mounting hole 4, connecting thread 5, torque head 6, fixed baffle 7, panel mounting seat 8, indexing portion 9, safety hole 10, return spring 11, compression spring 12, clamping end 13, spring limiting portion 14, control portion 15, fixing member 16, and clamping hole 17, the use of other terms is not excluded. These terms are used solely to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitations would be contrary to the spirit of the present invention.
