Description

Technical Field

[0001] This utility model relates to a foldable support structure for a door, specifically a foldable support structure for an energy chamber door that provides energy to food purification equipment, belonging to the field of food purification technology. Background Technology

[0002] In existing food purification equipment, the energy chamber is independent of the purification tank and is generally cabinet-shaped with a hinged door at the front. When repairing or replacing parts inside the energy chamber, manual opening of the door does not require auxiliary support components. To reduce the distance between the energy chamber and the purification tank, thereby overcoming the complexity of wiring into the purification equipment, the applicant has disclosed a modular industrial food purification device (patent application number 2024109612577). This device includes a power supply module, i.e., the energy chamber, which is positioned above the purification tank. Because the chamber is a rectangular parallelepiped extending above the purification tank, its door can only open upwards. Once opened, it is difficult to maintain the open position under gravity, especially given the height of the energy chamber. Even with manual maintenance, keeping the door open is challenging. Therefore, a foldable support structure for the door that allows it to remain open has become a goal pursued by those skilled in the art. Summary of the Invention

[0003] The purpose of this invention is to solve the problem of how to keep the energy chamber door of a purification device open when it is opened.

[0004] To achieve the above-mentioned objectives, the technical solution of this utility model is as follows: a foldable support structure for a door, characterized in that it includes: a cabin door panel with its upper end hinged to the top crossbeam of the cabin; a support rod fixing seat is provided on both sides of the inner surface of the cabin door panel; one end of the support rod is rotatably connected to the support rod fixing seat via a hinge; the free end of the support rod has a protruding pin; a socket for receiving the pin is provided on the bracket at the lower part of the cabin; the pin of the support rod is inserted into the socket; the support rod keeps the cabin door panel in an open state; and a support rod storage bracket for storing the support rod is provided on the support rod fixing seat.

[0005] As a preferred embodiment, the cabin door panel includes an inclined plate that is tilted upwards and hinged to the top crossbeam of the cabin, and a vertical plate that is connected to the free end of the inclined plate and is vertically downwards.

[0006] As a preferred embodiment, the support rod fixing seat includes a first base plate mounted to the upright plate and a second base plate perpendicular to and vertically arranged with respect to the first base plate; the support rod is connected to the second base plate via a hinge; the support rod storage bracket includes a support plate perpendicular to the upright plate and a storage plate vertically arranged at the end of the support plate, the storage plate having a U-shaped groove for storing the support rod, and the upper part of the U-shaped groove having an opening facing the support rod.

[0007] As a preferred embodiment, the angle between the line connecting the hinge at the end of the support rod to the U-shaped groove and the upright plate is 60 degrees.

[0008] The foldable support structure of the door described in this utility model, by adopting the above-mentioned technical solution, achieves stable support of the door when it is open and convenient storage when it is not in use through the ingenious combination of the cabin door panel, support rod, support rod storage bracket, support rod fixing seat and support rod positioning hole, thus avoiding interference with the internal structure of the equipment and greatly improving the convenience of equipment maintenance and usage efficiency. The matching design of the support rod and the support rod positioning hole ensures the stability of the support rod during the support process and avoids shaking or collapse caused by the weight of the cabin door panel or external force.

[0009] Furthermore, the foldable support structure of this utility model, through the positioning of the U-shaped groove in the storage plate, allows the support rod to be stored in the U-shaped groove. The angle between the support rod and the door panel is 60 degrees, which precisely prevents interference with the internal roof beams and other structures when the door is opened and rotated. Simultaneously, the U-shaped groove in the storage plate ensures precise positioning of the support rod during storage, avoiding damage or deformation caused by improper storage.

[0010] In summary, this utility model features a novel structure, reasonable design, and ingenious conception, exhibiting high versatility and adaptability. It is not only suitable for the energy chamber of air purifiers but can also be widely applied to other equipment requiring stable support for door panels. Furthermore, the components of this structure are all designed using standardized methods, facilitating production and assembly, reducing manufacturing costs, and improving production efficiency.

Detailed Implementation

[0017] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but these preferred embodiments should not be used to limit the scope of protection of the present invention.

[0018] See Figure 1 , 2 Figures 3 and 4 show the energy chamber of a food purifier. One side of the chamber body 100 has three chamber door panels 102. The chamber door panels 102 are equipped with the foldable support structure of the door described in this utility model, which realizes stable support when the door is open and convenient storage when not in use, avoids interference with the internal structure of the equipment, and greatly improves the ease of maintenance and efficiency of the equipment. Figure 2 In the middle, the rightmost hatch 102 is in the open state, while the middle and left hatch panels 102 are in the closed state.

[0019] See Figure 1-6The figure shows the foldable support structure of the door of the present invention, which includes: a cabin door panel 102, the upper end of which is hinged to the top crossbeam 101 of the cabin body 100 of the energy cabin. Specifically, the cabin door panel 102 includes an inclined plate 1021 and a vertical plate 1022. The inclined plate 1021 is inclined at the top and hinged to the top crossbeam 101 of the cabin body. The vertical plate 1022 is vertically connected downward to the free end of the inclined plate 1021. The inclined plate 1021 and the vertical plate 1022 are integrally formed. On both sides of the inner surface of the vertical plate 1022 of the cabin door panel 102, there are respectively provided... There is a support rod fixing seat 1, and two support rods 2 are respectively connected to the support rod fixing seat 1. One end of the support rod 2 is rotatably connected to the support rod fixing seat 1 through a hinge 5. The free end of the support rod 2 has a protruding pin 21. A socket 4 for receiving the pin 21 is provided on the bracket 103 at the lower part of the cabin. When the pin 21 of the support rod 2 is inserted into the socket 4, the support rod 2 keeps the cabin door 10 in the open state. A support rod storage bracket 3 is provided on the support rod fixing seat 1 for storing the support rod 2 in the closed state.

[0020] Specifically, the support rod fixing seat 1 includes a first seat plate 11 and a second seat plate 12. The first seat plate 11 is connected to the upright plate 1022, and the second seat plate 12 is perpendicular to the first seat plate 11 and vertically arranged on the outer edge of the first seat plate 11, that is, the second seat plate 12 is located in a plane perpendicular to the upright plate 1022. To improve the rigidity of the support rod fixing seat 1, it is best to provide a vertical stiffening rib between the two sides of the first seat plate 11 and the second seat plate 12. The first seat plate 11 is fixed to the upright plate 1022 by bolts. The support rod 2 is connected to the second seat plate 12 by a hinge 5, which ensures that the support rod 2 is in a plane perpendicular to the upright plate 1022 when in dry working condition, thus providing the best support stability. The support rod storage bracket 3 includes a support plate 31 and a storage plate 32. The support plate 31 is perpendicular to the upright plate 1022 and fixedly connected to the other side of the second base plate 12 (the side opposite to the support rod). The storage plate 32 is vertically disposed at the end of the support plate 31. A U-shaped groove 33 for storing the support rod is formed on the storage plate 32. An opening 34 is provided at the upper part of the U-shaped groove 33, facing the support rod. The support rod 2 is stored by rotating it into the U-shaped groove 33 through the opening 34. Preferably, the angle between the line connecting the hinge 5 at the end of the support rod to the U-shaped groove 33 and the upright plate 1022 is 60 degrees. This ensures that the support rod 2 forms a 60-degree angle with the upright plate 1022 after storage. The advantage is that when the door is opened and rotated, the support rod 2 will not interfere with the top beam or other structures inside the cabin.

[0021] The above description is illustrative only and not restrictive. The present invention aims to provide a foldable support structure for a door. Those skilled in the art will understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the claims. For example, the tilt angle of the support rod when it is retracted can be changed according to the arrangement of the components inside the cabin to avoid interference with the components. However, all of these will fall within the protection scope of the present invention.
