In addition, the existing bottom moving components of the display cabinet are mostly fixed structures, which cannot quickly adjust the spacing between the moving components according to the different sizes of the display cabinet, thus greatly reducing the convenience of adjusting the spacing of the moving components. To achieve the above objectives, this utility model provides the following technical solution: a multi-configuration conversion support structure device, comprising a housing assembly and four slides, each slide having a U-shaped seat at its bottom end, each U-shaped seat having a threaded locking rod on both sides, each U-shaped seat having a rotating shaft at its bottom end via bearings, each rotating shaft having a wheel frame at its bottom end, each wheel frame having a connecting shaft on its inner two walls via bearings, each connecting shaft having rollers on its outer side, each roller having several positioning grooves on one side of its outer side, and each wheel frame having a threaded control rod at its top side.

[0005] The outer shell assembly includes a display case body, and two bases are provided at the bottom of the display case body. Several slots are opened on both sides of the two bases, and a groove is opened in the middle of the bottom of the two bases. Two sliding rods are provided on the two inner walls of the two grooves.

[0006] More preferably, the slide rod and the slide block are configured to slide together.

[0007] More preferably, the internal dimensions of the groove are the same as the external dimensions of the slide.

[0008] More preferably, the threaded rod and the groove are configured with a snap-fit ​​structure.

[0009] More preferably, the rotating shaft and wheel frame are symmetrical about the vertical center line of the main body of the display case.

[0010] More preferably, the threaded control rod and the positioning groove are configured with a snap-fit ​​structure.

[0011] According to the foregoing description of this solution, the beneficial technical effects of this utility model include: This technical solution, through the cooperation of a rotating shaft, connecting shaft, and rollers, enables the multi-configuration conversion support structure device to quickly move the display case according to the user's needs during use, greatly improving the convenience of the display case body during movement. It also solves the problem of support failure caused by damage to the threads of the support legs due to dragging, thereby significantly improving the stability of the display case body during movement.

[0012] This technical solution, through the cooperation of the sliding rod and the sliding seat, enables the multi-configuration convertible support structure device to quickly adjust the distance between the two rollers according to the different sizes of the display cabinet during use. The cooperation of the threaded rod and the slot is used to fix the roller after the adjustment position, so as to avoid the roller displacement or misalignment during use, which greatly improves the convenience of adjusting the distance of the roller, thus meeting the requirements of the multi-configuration convertible support structure device.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 4 This utility model provides a technical solution: a multi-configuration conversion type support structure device, including a shell assembly 1 and four slides 2. The bottom of the four slides 2 is provided with a U-shaped seat 3. Both sides of the four U-shaped seats 3 are provided with threaded locking rods 4. The bottom of the four U-shaped seats 3 is provided with a rotating shaft 5 through a bearing. The bottom of the four rotating shafts 5 is provided with a wheel frame 6. The two inner walls of the four wheel frames 6 are provided with connecting shafts 7 through bearings. The outside of the four connecting shafts 7 is provided with rollers 8. Several positioning grooves 9 are respectively opened on one side of the four rollers 8. The top of one side of the four wheel frames 6 is provided with a threaded control rod 10.

[0020] like Figure 1 As shown, the outer shell assembly 1 includes a display case body 101. The bottom of the display case body 101 is provided with two bases 102. Several slots 103 are opened on both sides of the two bases 102. A groove 104 is opened in the middle of the bottom of the two bases 102. Two sliding rods 105 are respectively provided on the two inner walls of the two grooves 104.

[0021] like Figure 2 As shown, the slide bar 105 and the slide block 2 are connected by a sliding connection; this allows for quick adjustment of the distance between the two rollers 8 according to different sizes of display cases, greatly improving the convenience of adjusting the distance of the rollers 8.

[0022] like Figure 4 As shown, the internal dimensions of the groove 104 are consistent with the external dimensions of the slide block 2; this fixes the roller 8 after its position is adjusted, preventing the roller 8 from shifting or becoming misaligned during use.

[0023] like Figure 4As shown, the threaded rod 4 and the slot 103 are designed with a snap-fit ​​structure to fix the slide 2 after the position is adjusted, so as to prevent the slide 2 from shifting during use and thus increase the stability of the slide 2 during use.

[0024] like Figure 1 As shown, the rotating shaft 5 and the wheel frame 6 are symmetrical about the vertical center line of the display cabinet body 101. This enables the display cabinet to be moved quickly according to the user's needs, greatly improving the convenience of the display cabinet body 101 during movement. It also solves the problem of the support threads being damaged and the support failing due to dragging, thereby greatly improving the stability of the display cabinet body 101 during movement.

[0025] like Figure 3 As shown, the threaded control rod 10 and the positioning groove 9 are designed with a snap-fit ​​structure to fix the roller 8 and prevent the roller 8 from rotating during use. Thus, the six rollers 8 support the main body of the display case 101, thereby greatly reducing the manufacturing cost.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the spacing between the rollers 8 needs to be adjusted, the two slide blocks 2 are pushed, causing the slide blocks 2 to move the rollers 8 to the required spacing through the rotating shaft 5, in cooperation with the groove 104 and the slide rod 105. This allows for quick adjustment of the spacing between the two rollers 8 according to different sizes of display cases, greatly improving the convenience of adjusting the rollers 8. After the position adjustment of the rollers 8 is completed, the threaded locking rod 4 is rotated, causing the threaded locking rod 4 to engage in the slot 103, thus fixing the slide block 2 after the adjustment and preventing the slide block 2 from being damaged during use. In the event of displacement, when the position of the display case body 101 needs to be moved, the display case body 101 is pushed. At this time, the display case body 101 moves with the cooperation of the connecting shaft 7 and the rollers 8, realizing the rapid movement of the display case according to the user's needs. This greatly improves the convenience of the display case body 101 during movement and solves the problem of the support threads being damaged and the support failing due to dragging. This greatly improves the stability of the display case body 101 during movement. The rotating shaft 5 can provide different directions of steering with the rollers 8.
