Description

Technical Field

[0001] The utility model relates to the technical field of wine cabinet door support structures, and particularly relates to a door body support structure with universal wheels. Background Technique

[0002] The wine cabinet door body is generally configured with a glass door. The door body glass has two layers, three layers, etc. Due to the nature of the glass itself, the weight per unit area is much heavier than that of a foamed door body. The door body opens left and right, and a single-sided upper and lower door hinge is used to fix the door body for rotation and load-bearing use. There is a door hinge support on the side with the door hinge, and it will not sag. On the other side (the opening side), under the gravity of the door body itself, it will basically sag to varying degrees after long-term use. In order to prevent the door body from sagging, many wine cabinets sold on the market are equipped with a door support structure (also called a door support), which is generally assembled on the non-door hinge side (the opening side). In this way, there are support points on both sides of the door body, which can make the width direction of the door body parallel to the horizontal plane and prevent sagging. The conventional design of this kind of door support is a roller structure. When opening the door, it relies on the axial rotation of the roller to assist in opening the door. This is a line on the cylindrical surface of the roller that contacts the lower edge surface of the door body to generate support. The actual frictional force when opening the door is relatively large. For a large-sized door body, a large amount of force is still required to push and pull when opening the door. In order to solve the defects of existing ordinary door supports, a door support with a universal wheel structure is designed to achieve point-to-plane contact and 360° three-dimensional rotation, minimize the frictional force when opening the door, and make the opening and closing of the door smooth and labor-saving. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a door body support structure with universal wheels, which can effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A door body support structure with universal wheels includes a foamed box body. The lower surface of the foamed box body is fixedly connected with a door support plate. The inner bottom wall of the door support plate is fixedly connected with a universal wheel assembly, and a spherical ball is arranged on the inner wall of the universal wheel assembly.

[0006] In order to achieve the effect of fixing the universal wheel assembly, as a door body support structure with universal wheels of the utility model, a countersunk hole is opened on the inner bottom wall of the universal wheel assembly, a threaded hole is opened on the upper surface of the door support plate, and a universal wheel fixing screw is threadedly connected to the inner wall of the threaded hole.

[0007] In order to achieve the effect of installing rubber feet, as a door body support structure with universal wheels of the utility model, a fixed slot is opened on the upper surface of the door support plate, and a rubber foot is fixedly connected to the inner wall of the fixed slot.

[0008] In order to achieve the effect of fixing the door support plate, as a door body support structure with universal wheels in the present utility model, a fixing hole groove is provided on the upper surface of the door support plate, a screw hole seat is fixedly connected to the lower surface of the foam box body, and a flange surface screw is threadedly connected to the inner wall of the screw hole seat.

[0009] In order to achieve the effect of enclosing the foam box body, as a door body support structure with universal wheels in the present utility model, a back plate is fixedly connected to the inner wall of the back surface of the foam box body, a back frame plate is fixedly connected to the lower surface of the back plate, and a bottom plate is fixedly connected to the inner wall of the lower surface of the foam box body.

[0010] In order to achieve the effect of pushing the foam box body to move, as a door body support structure with universal wheels in the present utility model, a mounting plate is fixedly connected to the lower surface of the foam box body, and a moving wheel is arranged on the inner wall of the mounting plate.

[0011] In order to achieve the effect of installing the door body, as a door body support structure with universal wheels in the present utility model, an upper door hinge is fixedly connected to the upper surface of the foam box body, a lower door hinge is fixedly connected to the lower surface of the foam box body, and a support foot is fixedly connected to the lower surface of the lower door hinge.

[0012] In order to achieve the effect of directly observing the inside of the foam box body, as a door body support structure with universal wheels in the present utility model, a door body is hinged to the lower surface of the upper door hinge. The door body includes a door frame, a double-layer glass is fixedly connected to the inner wall of the door frame, and a door sealing strip is fixedly connected to the back surface of the door frame.

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

[0014] In the door body support structure with universal wheels, through the settings of the door body, the foam box body, the door support plate, the universal wheel assembly, and the ball, during the process of opening or closing the door body, the ball in the universal wheel assembly will rotate in multiple directions continuously driven by the door body. Among them, the ball always contacts the lower surface of the door body at one point. In this case, the contact resistance and friction between the point and the surface are the smallest. Therefore, when opening the door, the universal wheel can achieve an easy assisting effect to pull the door open. In the static state of closing the door without applying force, the ball serves as a support point to hold the non-door hinge side of the door body. In this way, there are support points on both the left and right sides of the door body, so that the center of gravity will not deviate and the door body will not sag. Thus, it can not only support the door, but also reduce the opening friction when opening the door, can easily pull the door open, and enable the door support structure to achieve point-to-face support, allowing for 360° three-dimensional rotation, minimizing the opening friction, and making the opening and closing of the door smooth and labor-saving.

In this way, there are support points on both the left and right sides of the door body 1, so that the center of gravity will not deviate and the door body 1 will not sag. Therefore, it can both support the door and reduce the opening friction when opening the door, can easily pull the door open, and enables the door support structure to achieve point-to-surface support, allowing for 360° three-dimensional rotation, minimizing the opening friction, and making the opening and closing of the door smooth and labor-saving.
