Description

Technical Field

[0001] The utility model relates to the field of detachable door panels, in particular to a hidden door panel latch. Background Art

[0002] The cabinet door is the door panel on the cabinet body, which enables the cabinet body to have the function of opening and closing. For laboratories, steel door panels are usually used. During the opening and closing process, the connection between the door panel and the cabinet body will always block part of the cabinet body, thus affecting the placement of items. At the same time, as a movable part, the door panel has a shorter lifespan than the cabinet body during long-term opening or closing. Therefore, it is necessary for the door panels used in the laboratory to be easily disassembled. However, the existing door panels are mainly installed by hinges, but the hinges are mainly fixed by screws. This installation method requires auxiliary tools to complete the disassembly of the door panels. For the environment in which items are frequently placed and taken in the laboratory, this door panel is not suitable. Utility Model Content

[0003] The purpose of the utility model is to solve the problems in the background technology and provide a hidden door panel latch. The door panel with this structure can be easily and quickly disassembled and assembled.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0005] A hidden door panel latch comprises a plate body, an L-shaped latch base bracket, a latch rod, a spring and a directional shaft cap, wherein the latch rod can be slidably mounted on the L-shaped latch base bracket, the L-shaped latch base bracket is fixed to the inner top of one end of the plate body, and the latch rod is vertically arranged, the spring is sleeved on the latch rod, and the top end of the latch rod can be extended out of the plate body through the spring, the directional shaft cap is coaxially arranged with the latch rod, and the directional shaft cap is installed at the bottom of the plate body, the bottom end of the directional shaft cap passes through the plate body and is placed outside the plate body, and a strip inspection hole matching the latch rod is vertically processed on the plate body outside the latch rod.

[0006] The latch rod is processed with a flat portion for limiting the spring.

[0007] The hidden door panel latch provided by the utility model has the beneficial effect that an L-shaped latch base bracket is provided, the latch rod is installed on the L-shaped latch base through a spring, and the latch rod can be completely received into the panel body in conjunction with the strip inspection hole, so that the door panel can be removed quickly and conveniently.

[0014] Example

[0015] like Figure 1 to Figure 3 As shown, the hidden door panel latch provided in this embodiment includes a plate body 1, an L-shaped latch base bracket 2, a latch rod 3, a spring 4 and a directional shaft cap 5, the latch rod 3 can be slidably installed on the L-shaped latch base bracket 2, the L-shaped latch base bracket 2 is fixed to the inner top of one end of the plate body 1, and the latch rod 3 is vertically arranged, the vertically arranged latch rod 3 can vertically extend out of the plate body 1 and connect with the cabinet body, playing the role of a hinge, the spring 4 is sleeved on the latch rod 3, and the latch rod 3 is processed with a flat portion 6 for limiting the spring 4, and the top end of the latch rod 3 can be extended out of the plate body 1 through the spring 4. The latch rod 3 can select a T-shaped or L-shaped structure, and the latch rod 3 of these two structures cooperates with the spring 4 The methods are all existing technologies and will not be described in detail here. The directional shaft cap 5 is coaxially arranged with the latch rod 3, and the directional shaft cap 5 is installed at the bottom of the plate body 1. The bottom end of the directional shaft cap 5 passes through the plate body 1 and is placed outside the plate body 1. The directional shaft cap 5 cooperates with the latch rod 3 to support the plate body 1. In order to conveniently control the latch rod 3, a strip inspection hole 7 adapted to the latch rod 3 is vertically processed on the plate body 1 outside the latch rod 3. The latch rod 3 can reciprocate in the strip inspection hole 7. The strip inspection hole 7 can usually be blocked by a cover plate to ensure the beauty of the plate body 1. At the same time, it can reduce oxidation and rusting caused by the increased contact area between the L-shaped latch base bracket 2, the latch rod 3 and the spring 4 and the external air.

[0016] The method of using the utility model is:

[0017] During installation, if Figure 4 As shown, the directional shaft cap 5 is inserted into the positioning hole at the bottom of the cabinet, and then the latch rod 3 is pressed down. At this time, the spring 4 is compressed, and then the latch rod 3 is aligned with the positioning hole at the top of the cabinet, and the latch rod 3 is released. Under the action of the spring 4, the latch rod 3 extends into the positioning hole at the top of the cabinet. At this time, the plate body 1 is connected to the cabinet through the directional shaft cap 5 and the latch rod 3.

[0018] During disassembly, push the latch rod 3 downward from the strip inspection hole 7, at which time the spring 4 is compressed, and then move the top of the plate body 1 out of the cabinet, then lift the plate body 1 upward, and move the directional shaft cap 5 out of the cabinet to complete the disassembly of the plate body 1.

[0019] The hidden door panel latch disclosed in this patent is small in size and integrated in the panel body 1, which effectively increases the usable space inside the cabinet, while reducing contact with the outside air and effectively avoiding oxidation and rusting; it has a simple structure and is low in cost compared to existing hinges; it is easy to operate and can achieve rapid disassembly and assembly of the panel body 1.

[0020] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any modification and replacement based on the technical solution and the utility model concept provided by the present invention shall be included in the protection scope of the present invention. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale, and the present invention omits the description of known components and processing technologies and processes to avoid unnecessary limitations on the present invention.
