[0041] like Figure 1-2 As shown, the arc-shaped sliding door of the present invention includes a

[0042] Curved door 1;

[0043] The left sliding part and the right sliding part have the same structure and are symmetrically arranged on both sides of the arc door 1; the structure of the left sliding part / right sliding part includes

[0044] The arc-shaped slide rail 11 is composed of an arc-shaped vertical plate and an arc-shaped horizontal plate, and the arc-shaped vertical plate and the arc-shaped horizontal plate form an integrated structure. The arc-shaped slide rail 11 has an L-shaped cross section and is arranged on the side edge of the arc-shaped door 1;

[0045] A supporting unit, used to connect the cabinet 30 and the curved door 1, and enable the curved door 1 to slide open and close;

[0046] The support unit has

[0047] A movable support arm 12, the bottom of the movable support arm 12 is connected to the lower end of the arc door 1, and the top of the movable support arm 12 is hinged to the cabinet 30, so that the arc door 1 can rotate around the hinge;

[0048] The fixed support arm 13 has a bottom connected to the cabinet 30, and a limiting unit is provided on the top of the fixed support arm 13 for limiting the unit and supporting the curved door 1

[0049] The telescopic rod 14 is a nitrogen spring. The bottom end of the telescopic rod 14 is hinged to the cabinet 30, and the top end of the telescopic rod 14 is hinged to the middle of the movable support arm 12, which is used to restrict the rotation range of the movable support arm 12, so that the arc door 1 is in a specified position when it is fully opened, and provide a certain elastic force to prevent the arc door 1 from falling back. In the process of opening the arc door 1, the nitrogen spring releases the compressed elastic potential energy to achieve a labor-saving function; in the process of closing the arc door 1, the telescopic rod 14 provides a certain resistance to prevent the arc door 1 from falling too fast and damaging the arc door 1, the cabinet 30 and the telescopic rod 14;

[0050] The limiting unit is used to limit the movement track of the arc-shaped slide rail 11 so that the arc-shaped door 1 slides within a certain space;

[0051] like Figure 3-7 As shown, the limit unit has

[0052] A mounting base 21, disposed on the top of the fixed support arm 13;

[0053] The upper limit part has an upper limit base 22, a vertical spring tightening device is arranged on the upper limit base 22, and a limit bearing 23 is arranged on the top of the vertical spring tightening device. The rolling surface of the limit bearing 23 contacts the top surface of the arc-shaped horizontal plate to form a high-pair structure, which is used to limit the movement of the arc door 1 along the outer normal direction of the arc door 1 during the opening / closing process of the arc door 1;

[0054] The vertical spring tightening device is composed of a vertical movable shaft 24, a limit screw 25 and an upper limit spring 26. The vertical movable shaft 24 is inserted into the through hole of the upper limit base 22. The limit screw 25 is fixedly connected to the vertical movable shaft 24 through a through hole above the through hole of the upper limit base 22, so as to limit the range of up and down movement of the vertical movable shaft 24. A bolt is sleeved on the lower end of the vertical movable shaft 24, and a limit mounting ring is arranged at the lower part of the through hole arranged in the upper limit base 22. The limit mounting ring and the upper limit base 22 are an integral structure to limit the downward displacement of the vertical movable shaft 24. An upper limit spring 26 is arranged between the bolt and the limit mounting ring to tighten the vertical movable shaft 24. The upper limit portion acts on the arc slide rail 11 to limit the movement of the arc slide rail 11 along its outer normal direction, and at the same time, the arc slide rail 11 has a certain amount of activity along its outer normal direction to prevent the arc door 1 from getting stuck during the opening / closing process.

One end of the side limit spring 212 is in contact with the horizontal movable shaft 211. A spring baffle 213 is provided at the other end of the side limit spring 212. The spring baffle 213 is used to fix and compress the side limit spring 212, so that the side limit spring 212 presses against the horizontal movable shaft 211, so that the universal ball 210 presses against the side of the horizontal plate of the arc slide rail 11, limits the lateral movement of the arc door 1, and provides a certain amount of lateral movement of the arc door 1 to prevent the arc door 1 from getting stuck during the opening / closing process.

[0058] The lower limit part has a lower limit base 214, and a support bearing 215 is arranged on the lower limit base 214. The rolling surface of the support bearing 215 contacts the bottom surface of the arc-shaped horizontal plate to form a high-pair structure, which is used to support the arc door 1 during the opening / closing process of the arc door 1;

[0059] The upper limit base 22 , the side limit base 28 and the lower limit base 214 are fixedly connected to the mounting base 21 respectively.

[0060] like Figure 8-9 As shown, the working process of the present invention is as follows:

[0061] When opening the curved door 1, the hand acts on the curved door 1, and the curved door 1 is rotated around the movable support arm 12 at the hinge of the cabinet 30 through the action of the movable support arm 12 on the curved door 1 and the limiting action of the limiting unit on the curved slide rail 11. The limiting unit limits the sliding of the curved door 1 along the arc, and the telescopic rod 14 constrains the rotation range of the curved door 1. In addition, in the process of opening the curved door 1, the telescopic rod 14 releases the compressed elastic potential energy, which saves effort in the process of opening the curved door 1. When the curved door 1 is fully opened, the center of gravity moves backward, and gravity acts on the curved door. In addition, the telescopic rod 14 provides a certain elastic force to prevent the curved door 1 from falling back, so that the curved door 1 is always in a fixed position to complete the opening action.

[0062] When closing the curved door 1, the hand acts on the curved door 1, and the curved door 1 rotates around the movable support arm 12 at the hinge of the cabinet 30 through the action of the movable support arm 12 on the curved door 1 and the limiting action of the limiting unit on the curved slide rail 11. The limiting unit limits the sliding of the curved door 1 along the arc, and the telescopic rod 14 constrains the rotation range of the curved door 1. At the same time, the telescopic rod 14 has a certain resistance when it is retracted, so as to prevent the curved door 1 from falling too fast and damaging the curved door 1, the cabinet 30 and the telescopic rod 14. The curved door 1 falls completely and the closing action is completed.

[0063] The present invention adopts an arc-shaped sliding switching method, and the arc-shaped slide rail 11 is embedded in the arc-shaped door 1, which greatly reduces the space occupied by the switching process, and the staff does not need to move during the switching process; the support unit has the function of saving effort and protecting the device during the switching process, thereby improving the operating comfort; the side limit part, the upper limit part and the contact and matching part with the arc-shaped slide rail 11 all adopt a structure that can move within a certain range, allowing a larger error range for processing and assembly, greatly improving the smoothness of sliding and reducing the risk of jamming.
