Detailed ways

The content of the present utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Example:

Referring to FIGS. 1-5 , the cabinet door shaft installation and disassembly structure provided by this embodiment includes an upper door shaft 1 , a lower door shaft 2 , an upper door shaft seat 3 and a cabinet door 4 .

Wherein, as shown in FIG. 5 , the axial middle portion of the lower door shaft 2 protrudes to form a blocking shoulder 21 to divide the lower door shaft into two parts. The lower half of the door shaft is used to penetrate the lower door of the cabinet body. The shaft mounting hole cannot be rotated, and the upper half of the door shaft is inserted into the lower door shaft mounting hole at the bottom of the cabinet door. In this way, the lower door shaft 2 can be realized by being provided with a blocking shoulder 21 in the axial middle of the lower door shaft 2. And the quick installation of the bottom of the cabinet body and cabinet door 4.

And the top of this cabinet door is reserved to be provided with upper door shaft seat installation position, is provided with screw hole 31 in the upper door shaft seat 3 to be installed in the upper door shaft seat installation position by screw, one end of upper door shaft 1 contacts with upper door shaft seat, The other end passes through the upper door shaft installation hole at the top of the cabinet door and is inserted into the upper door shaft installation hole of the cabinet body.

The assembly process of the cabinet door shaft is as follows: first place the lower door shaft 2 on the corresponding hole of the cabinet body, then install the cabinet door 4, then insert the upper door shaft 1 from the upper door shaft installation hole, use the cabinet door and cabinet The shearing force of the body on the upper door shaft fixes the upper door shaft so that it does not fall down, then install the upper door shaft seat to support the upper door shaft, and finally screw on the screws. It can be seen from the above that, because the door shaft assembly and disassembly structure of the cabinet body provided by this embodiment is detachable and installed among its various components, it can realize fast detachable installation and improve installation efficiency.

Specifically, the lower door shaft installation hole of the above-mentioned cabinet is in the shape of a regular hexagon, and the shape of the lower half of the lower door shaft 2 corresponds to the shape of the lower door shaft installation hole of the cabinet body, and is also a regular hexagonal shape, so that the lower door shaft 2. The lower half is inserted in the lower door shaft mounting hole of the cabinet and cannot be rotated. And the shape of the upper half of the lower door shaft 2 is cylindrical, and the lower door shaft sleeve 5 is fixedly installed in the lower door shaft mounting hole at the bottom of the cabinet door, and the lower door shaft upper part is inserted into the lower door shaft sleeve 5 In order to make the cabinet door 4 rotate more smoothly around the lower door shaft 2.

Correspondingly, an upper door shaft sleeve 6 is sleeved in the upper door shaft installation hole, the overall shape of the upper door shaft 1 is cylindrical, and the bottom circumference of the upper door shaft 1 extends outward to form a blocking portion 11, so that the upper door shaft 1 The bottom circumference diameter is greater than the inner diameter of the upper door shaft sleeve 6, which prevents the upper door shaft 1 from fully penetrating into the upper door shaft sleeve 6, thereby allowing the cabinet door 4 to rotate more smoothly around the upper door shaft 1.

The above-mentioned embodiments are only to illustrate the technical concept and characteristics of the present utility model, and its purpose is to allow those of ordinary skill in the art to understand the content of the present utility model and implement it accordingly, and cannot limit the protection scope of the present utility model with this . All equivalent changes or modifications made according to the essence of the content of the utility model shall fall within the scope of protection of the utility model.
