This track system is often used in commercial and industrial places, such as shops, exhibition halls and warehouses. It can effectively support and slide large display cabinet doors, providing convenient use and stable support.

[0003] A Chinese patent discloses a museum display cabinet translation opening system (Announcement No. CN206342247U). The patent adopts a modular design. The entire module can be pulled out, and then the special track profile is pushed and pulled left and right to achieve the door opening effect. It can be completely hidden, has a good sealing effect, is easy to install, and is easy to use. The weight bearing capacity of the laminated glass is transferred to the display cabinet base through a special track profile and a fixed type material. The safety factor is high, the caliber of the door opening is greatly improved, and it is convenient to use. However, most of the existing display cabinets use glass display cabinets, the cabinet doors are made of glass, and a single wheel track is used for opening and closing. This traditional museum display cabinet opening door is large and heavy, and the safety level is low.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1: Please refer to Figure 1-Figure 5 In the embodiment of the utility model, a heavy-duty track for a display cabinet sliding door includes an inspection door panel 1, which is movably installed. The device can be repaired by taking out the inspection door panel 1. The inspection door panel 1 is fixedly installed at the bottom end of the cabinet partition 3. The inspection door panel 1 and the cabinet partition 3 are connected to the glass plate 2 through a heavy-duty track mechanism 4; the glass plate 2 and the top of the movable door aluminum plate 6 are adapted to each other, and the glass plate 2 is fixed by gluing;

[0024] The heavy track mechanism 4 includes a track slide 5, and a movable door aluminum plate 6 for sliding is arranged on the side of the track slide 5. The movable door aluminum plate 6 rotates with the track slide 5 through a rolling bearing 8. The track slide 5 and the rolling bearing 8 are sleeved with each other (the error value is between 0.03mm). A plurality of hard optical axes 7 are fixedly sleeved on the side of the track slide 5. A limit plate 14 is arranged in the inner cavity at the bottom end of the movable door aluminum plate 6 to limit the movement of the movable door aluminum plate 6. The movable door aluminum plate 6 and the track slide 5 in the device are made of high-strength and hardness aluminum alloy 6063 material; specifically, the rolling bearing 8 is made of high-precision stainless steel and then manufactured by high-precision machining technology to improve the sliding accuracy and ensure good sliding performance. The connection structure of a whole row of pulleys and tracks is adopted to effectively improve the safety and flexibility of the display cabinet door body.

[0025] See also Figure 5The heavy-duty track mechanism 4 also includes a connecting plate 15 fixedly installed in the inner cavity of the bottom end of the movable door aluminum plate 6. A first bearing 16 is provided at one end of the connecting plate 15 away from the movable door aluminum plate 6. An inner shaft 17 is rotatably sleeved in the inner cavity of the first bearing 16, and both ends of the inner shaft 17 are rotatably sleeved at both ends of the first bearing 16.

[0026] Example 2: Please refer to Figure 1-Figure 5 , based on Example 1, the side of the rolling bearing 8 is rotatably sleeved with a connecting shaft 11, and the side of the connecting shaft 11 is fixedly connected with a threaded shaft 12, and two pulleys are installed at the bottom end of the rolling bearing 8, and the pulleys are rotatably connected through the rotating shaft, and the periphery of the pulley is in contact with the bottom of the sliding groove opened on the side of the movable door aluminum plate 6;

[0027] See also Figure 3 and Figure 5 One end of the threaded shaft 12 passes through the side of the track slide rail 5 and is threadedly rotated and sleeved with a nut 13. The nut 13 can be used to limit the threaded shaft 12 to prevent the threaded shaft 12 from shaking;

[0028] See also Figure 5 The bottom of the limit plate 14 is fixedly connected with the base 10, and the base 10 is fixedly installed on the side of the cabinet. The limit plate 14 and the first bearing 16 are slidably sleeved with each other. When the movable door aluminum plate 6 and the cabinet are completely closed, the first bearing 16 will completely enter the inner cavity of the limit plate 14, which is a complete stroke, so that the movable door aluminum plate 6 and the track slide rail 5 will not be loose or shaken;

[0029] See also Figure 2 Two slide grooves 9 are provided on the side of the movable door aluminum plate 6. The two slide grooves 9 are arranged opposite to each other up and down, and the outer dimensions of the slide grooves 9 and the rolling bearing 8 are adapted to each other.

[0030] The working principle of the utility model is as follows: before using the device, the track slide 5 needs to be fixedly installed on the side of the cabinet, and fixedly sleeved with the hard optical shaft 7, the other end of the hard optical shaft 7 is fixedly connected with a cylinder, and then the rolling bearing 8 is installed in the side inner cavity of the movable door aluminum plate 6, and connected with the track slide 5 through the connecting shaft 11, the threaded shaft 12 and the nut 13, and then the glass plate 2 is installed on the top of the movable door aluminum plate 6. When the device needs to be used, the cylinder is first driven to drive the hard optical shaft 7 to perform telescopic movement. When the hard optical shaft 7 is extended and retracted, the track slide 5 and the movable door aluminum plate can be retracted and retracted. The movable door aluminum plate 6 and the glass plate 2 are moved out of the inner cavity of the cabinet, and then the glass plate 2 is pushed horizontally to make the movable door aluminum plate 6 slide on the side of the track slide rail 5. When the movable door aluminum plate 6 is moved out of the inner cavity of the cabinet, the connecting plate 15, the first bearing 16 and the inner shaft 17 can be driven to move out of the inner cavity of the limit plate 14. In the process of pushing the movable door aluminum plate 6, the connecting plate 15, the first bearing 16 and the inner shaft 17 can be driven to move, thereby improving the smoothness of the movable door aluminum plate 6 when moving, and the object can be placed after the movable door aluminum plate 6 is moved.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
