Description
Technical Field
[0001] The utility model relates to the field of cabinets, in particular to a cabinet. Background Art
[0002] A cabinet is a storage device for installing various electrical appliances or mechanical components. The cabinet includes a door frame and a door. When using a traditional cabinet, it is not easy to control the opening and closing limit of the door when opening and closing the door, which not only makes it easy for the door to collide with external adjacent objects after opening and closing, but also makes it easy for the door to close automatically after opening. In addition, after frequent opening and closing, the hinge connecting the door and the threshold loosens, causing the door to sag and cannot be closed normally.
[0003] In view of this, it is necessary to provide a cabinet. Summary of the invention

[0007] Furthermore, the No. 1 plate includes a vertical plate fixedly connected to the inner side of the door and a horizontal plate fixedly connected to the lower end of the vertical plate, the vertical plate is provided with a plurality of mounting holes, and the strip holes are provided on the horizontal plate.
[0008] Furthermore, both ends of the strip-shaped hole are arranged as arc structures, and the No. 1 column can be offset against the arc structure.

[0016] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.
[0017] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present application provides a cabinet, whose structure includes a door frame 1 and a door 2 hingedly connected to the door frame 1, and also includes a limiting mechanism 3 connecting the door 2 and the door frame 1 and a lifting mechanism 4 arranged on the lower end surface of the door 2, the limiting mechanism 3 includes a connecting strip 31, a No. 1 column 32 arranged at one end of the connecting strip 31, and a No. 1 plate 33 fixedly arranged on the inner side of the door 2, the other end of the connecting strip 31 is hinged to the sill of the door 2, the No. 1 plate 33 is provided with a strip hole 301 extending along the width of the door 2, the No. 1 column 32 is slidably connected to the strip hole 301, and the lower edge of the lifting mechanism 4 protrudes from the lower end surface of the door 2.
[0018] In actual use, when the door 2 needs to be opened, when the door 2 is opened to a certain angle, the first column 32 abuts against one end of the strip hole 301, restricting the door 2 from opening further. After the cabinet has been used for a long time, the door 2 is frequently opened and closed, causing the hinge to loosen, so the door 2 sinks. When the door 2 is closed, when the door 2 moves toward the door 2 threshold, sliding friction is formed between the lifting mechanism 4 and the door 2 threshold, and the lifting mechanism 4 guides the door 2 obliquely upward, so that the door 2 can be closed with the door frame 1.
[0019] In the above design, the structural design of the limit mechanism 3 can effectively limit the opening and closing of the door 2, and can also prevent the door 2 from automatically closing after opening. The structural design of the lifting mechanism 4 can effectively lift the door 2 to ensure that the door 2 and the door frame 1 are closed normally.
[0020] Specifically: Figure 2 and Figure 3 As shown, the first plate 33 includes a vertical plate 331 fixedly connected to the inner side of the door 2 and a horizontal plate 332 fixedly connected to the lower end of the vertical plate 331, and the vertical plate 331 is provided with a plurality of first mounting holes 302, and the strip holes 301 are provided on the horizontal plate 332. The inner side of the door 2 is provided with a plurality of second mounting holes 201 arranged along the width direction for mounting the vertical plate 331.
[0021] In actual use, the vertical plate 331 is fixed to the inner side of the door 2 by external bolts. When the door 2 is opened or closed, the vertical plate 331 drives the horizontal plate 332 to move synchronously. When the limit mechanism 3 needs to be adjusted, the vertical plate 331 is installed on a different second installation hole 201 by passing the bolt through the first installation hole 302.
[0022] In the above design, the structural design and specific implementation method of plate No. 1 33 can effectively realize the fixed connection between door 2 and plate No. 1 33 and the sliding guidance of plate No. 1 33 to column No. 1 32. The design of mounting hole No. 2 201 facilitates the adjustment of limiting mechanism 3 to ensure that the limiting angle of limiting mechanism 3 can be adjusted.
[0023] Specifically: Figure 3 As shown, both ends of the strip-shaped hole 301 are arranged as arc structures 303 , and the first column 32 can abut against the arc structure 303 .
[0024] In actual use, when the first column 32 moves to the right position to limit the door 2 , the first column 32 abuts against the arc structure 303 at one end of the strip hole 301 .
[0025] In the above design, the structural design and specific implementation of the strip hole 301 can effectively achieve the travel limit of the first column 32.
[0026] Specifically: Figure 2 As shown, the lifting mechanism 4 includes a mounting strip 41 arranged on the inner side of the door 2, and a roller 42 arranged at the lower end of the mounting strip 41, the lower end of the roller 42 protrudes from the lower end surface of the door 2, and the rotating axis of the roller 42 is parallel to the width.
[0027] In actual use, when the door 2 is closed, the lower end of the roller 42 first contacts the door 2 threshold and rolls with the door 2 threshold, and then the door 2 and the door 2 threshold are closed.
[0028] In the above design, the structural design and specific implementation method of the lifting mechanism 4 can effectively guide the lifting of the door 2 when the door 2 is closed, thereby preventing the door 2 from being unable to close.
[0029] In the above design, the structural design and specific implementation method of the lifting mechanism 4 can effectively realize the smooth closing of the door 2.
[0030] Specifically, the lower edge of the roller 42 protrudes from the lower end of the door 2 by 3 mm to 4 mm.
[0031] In actual use, the assembly gap between the door 2 and the door frame 1 is generally 3 mm to 4 mm.
[0032] In the above design, it can be effectively ensured that the roller 42 will not interfere with the door frame 1 when the door 2 rotates.
[0033] To further explain in detail, it should be understood that the above is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
