Technical Field

[0001] This utility model relates to the technical field of display case door support devices, and in particular to a display case sliding door structure. Background Technology

[0002] Display cases are essential for exhibition halls, museums, and other venues, used to carry exhibits. However, in the manufacturing process of display cases, the installation of the cabinet doors is often a complex process. Traditionally, multiple people work together to install the doors. Two people lift the doors and keep them parallel, then raise them to a designated position and keep them stable. The remaining workers then install the hinges. This requires a large number of workers, which increases production costs. Furthermore, manual lifting cannot keep the doors stable, resulting in misalignment or even damage after installation, which affects normal production. Utility Model Content

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0027] Specific implementation method one: Combining Figure 1-7 As shown, a sliding door structure for a display case includes: a trolley 1, a platform 2, and a support plate 3; the trolley 1 has multiple vertically arranged guide columns 101 on top, and an adjusting rod 102 is located at the center of the multiple guide columns 101; the platform 2 has through holes machined at its four corners, which are slidably connected to the guide columns 101; the threaded hole in the middle of the platform is threadedly connected to the adjusting rod 102; the right side of the platform 2 has a cantilever 4, which has a support position arranged at an angle to the horizontal plane; the bottom of the support plate 3 is connected to the cantilever 4 by a pivot, and the back is in contact with the support position. During the pushing process, it can maintain the stability of the cabinet door in its placement state, and form a positioning support after flipping to the horizontal. The flipping design of the support plate 3 can solve the problem of movement in relatively narrow spaces.

[0028] In use, the cabinet door is fixed on the support plate 3, the trolley 1 is pushed to the front of the cabinet to be installed, the position is adjusted, and the sliding door operation is realized. Then, the support plate 3 is flipped to a horizontal position. Then, one side of the hinge is installed to the right edge of the cabinet door, and the other side is installed to the cabinet body to realize the installation of the cabinet door. For the installation of multiple hinges on the cabinet door, the installation method from both sides to the middle is adopted to improve the installation accuracy and finished product quality. This solves the problem that traditional manual lifting cannot maintain stability and there is wobbling. At the same time, the number of workers is reduced during the installation process, and the manufacturing cost is reduced. If the installation height of the cabinet door is not suitable, the horizontal position of the support plate 3 can be adjusted by rotating the adjusting rod 102.

[0029] Preferred embodiments, in combination Figure 1 and Figure 7 As shown, the trolley 1 has a storage space 103 below it, which can be used to place multiple cabinet doors, so that continuous operation can be carried out without frequent handling of cabinet doors.

[0030] Preferred embodiments, in combination Figure 3 As shown, the support plate 3 has multiple hook plates 301 on both sides and a bottom support plate 302 below. The hook plates 301 contact the edge of the cabinet door to prevent damage to the glass area and support the cabinet door after it is flipped over. The bottom support plate 302 positions the bottom of the cabinet door and works with the hook plates 301 to temporarily place the cabinet door.

[0031] Preferred embodiments, in combination Figure 2 and Figure 4 As shown, the cantilever 4 includes an extension plate 5 and a bracket 6. One end of the extension plate 5 is welded to the platform 2, and the upper part is also welded and fixed to the bracket 6. The bracket 6 has an inclined support surface 601, and the angle between the support surface 601 and the horizontal plane is about 60 degrees. After the cabinet door is placed, it can maintain the stability of the overall structure when pushed, and avoid accidental tipping. A main shaft 602 connected to the support plate 3 is provided on the lower right side of the bracket 6, and a positioning plate 603 is provided below the main shaft 602. When the support plate 3 is flipped to the horizontal position, the surface contacts the positioning plate 603 to achieve the function of support and positioning.

[0032] Preferred embodiments, in combination Figure 6 and Figure 7 As shown, in order to reduce the stress on the main shaft 602 and improve the stability of the structure, a tie rod 604 is provided in the middle of the bracket 6. A rope of a certain length is used, with one end fixed to the tie rod 604 and the other end fixed to the support plate 3. After the support plate 3 is flipped to a horizontal state, the tension can be used to help the support plate 3 maintain a horizontal position, thereby reducing the stress on the main shaft 602.

[0033] In a preferred embodiment, to facilitate adjustment of the installation gap between the cabinet door and the cabinet body, combined with Figure 5 As shown, by changing the fixed connection between the extension plate 5 and the bracket 6, the extension plate 5 is provided with a slide rail 501, and the bracket 6 is provided with a slider 605 connected to the slide rail 501. The two are connected to form a sliding connection. By pulling the bracket 6 to move along the slide rail 501, the gap can be adjusted. Since no horizontal thrust is generated during the installation process, the horizontal positioning problem of the bracket 6 can be ignored. In order to improve the stability of the structure, a small threaded hole can also be machined on the side of the slider 605. With the screw and the small threaded hole, the screw is used to press the washer, so that the washer contacts the side of the extension plate 5 and the positioning is achieved by friction.

[0034] Preferred embodiments, in combination Figure 5 As shown, a stabilizing plate 606 is provided on the right side of the slider 605, which contacts the upper surface of the extension plate 5. By contacting the top surface of the extension plate 5, the contact area is increased, the supporting force on the bracket 6 is improved, and the stability is enhanced.

[0035] Preferred embodiments, in combination Figure 6 As shown, a panel 607 is provided at the support surface 601 to increase the contact area with the back of the support plate 3 and improve stability.

[0036] Preferred embodiments, in combination Figure 6 As shown, a magnet 608 is provided on the panel 607, which can be attracted by magnetic force to improve the stability of the support plate 3 in the tilted state.

[0037] Combination Figure 2 As shown, the four corners of the bottom of the trolley 1 are equipped with casters with locking mechanisms, which facilitates the movement of the trolley and can lock and position it after it is moved to the designated position; the left side of the trolley 1 is designed with a handle for easy pushing by staff.

[0038] The overall assembly forms a sliding door structure for the display case doors, ensuring overall stability and reliability. It also maintains horizontal stability during installation, improving installation quality and accuracy, reducing personnel involvement, and lowering manufacturing costs.
