Technical Field

[0001] The utility model relates to the technical field of display racks, in particular to a foldable display rack. Background Art

[0002] Ball display racks are a type of shelf system used to display and showcase ball products. They are usually made of metal or plastic and have multiple layers of shelves to display different types and sizes of balls, such as basketballs, footballs, tennis balls, volleyballs, etc. This display rack is usually made of metal or plastic, providing stable support and adjustable functions to accommodate different sizes and types of balls.

[0003] The application number in the existing public technology is: CN202321488692.X A foldable spherical display stand comprises a bottom plate and a frame body arranged on the bottom plate, the frame body comprising vertical support rods, support rods and auxiliary support rods; the vertical support rods are provided with at least two groups, and at least one side of each group of vertical support rods is provided with a support rod and an auxiliary support rod; the vertical support rods are provided with a plurality of first grooves for accommodating the support rods and the auxiliary support rods, one end of the support rods is rotatably connected to the first groove, and one end of the auxiliary support rod is rotatably connected to the middle part of the support rod; when unfolded, the other end of the auxiliary support rod is against the vertical support rod and is limited on the vertical support rod, and the auxiliary support rod supports the support rod at an oblique upward angle; when folded, the support rod and the auxiliary support rod are both rotated and folded in the first groove. The utility model can display products and fold them for storage in a variety of ways by setting the support rods in a foldable form, thereby increasing the use space of the display stand after storage and facilitating transportation.

The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0030] According to an embodiment of the utility model, a foldable display stand is provided.

[0031] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-4 As shown, a foldable display stand according to an embodiment of the utility model includes a display stand body 1 and a lockable movable wheel 16, a first screw rod 2 is provided at an inner position on one side surface of the display stand body 1, one end of the first screw rod 2 passes through the top position of the display stand body 1 and is connected to the second brake motor 11, a movable platform 3 is sleeved at the outer peripheral position of the first screw rod 2, a first brake motor 4 is installed at one side position of the top of the movable platform 3, one end of the first brake motor 4 passes through one side of the movable platform 3 and is connected to a drive shaft 20, a support plate 19 is fixedly installed at the outer peripheral position of the drive shaft 20, a second screw rod 18 is installed at the middle position of the top surface of the support plate 19, one end of the second screw rod 18 passes through one side of the support plate 19 and is connected to the third brake motor 17, a movable seat 6 is sleeved at the outer peripheral position of the second screw rod 18, a plurality of groups of electric push rods 5 are symmetrically installed at the top position of the movable seat 6, a loading plate 7 is installed at the top position of the electric push rod 5, and an inclined groove is provided at the middle position of the top of the loading plate 7.

[0032] In one embodiment, gear plates 10 are symmetrically connected to the surfaces of both sides in the middle of the display rack body 1, a connecting shaft 9 is installed between the gear plates 10, and a support arm 8 is symmetrically installed on the surface of the connecting shaft 9. A gear plate 13 is meshed and connected to one side of the gear plate 10, and a plurality of groups of limit sliders 14 are symmetrically installed at the bottom ends of both sides of the gear plate 13. Limit grooves 12 are provided on the outer periphery of the limit sliders 14 at both sides of the surfaces in the middle of the display rack body 1, and the limit sliders 14 are slidably connected to the limit grooves 12. A hydraulic rod 15 is installed at the bottom end of the limit groove 12, and the top of the hydraulic rod 15 is fixed to the gear plate 13. The setting of the limit sliders 14 and the limit grooves 12 is to ensure the movement stability of the gear plate 13, thereby ensuring that it can smoothly unfold and fold the support arm 8 for storage.

[0033] In one embodiment, a base 21 is welded at the bottom of the display stand body 1 .

[0034] In one embodiment, a plurality of sets of lockable movable wheels 16 are symmetrically installed on both sides of the bottom of the base 21. The arrangement of the lockable movable wheels 16 facilitates the movement of the display stand and facilitates subsequent display use.

[0035] In one embodiment, a slot is provided on the surface of the mobile platform 3 for the support plate 19 to rotate. The slot ensures that the support plate 19 can rotate under the drive of the first brake motor 4, thereby facilitating subsequent operations of taking and placing the ball and facilitating display and use.

[0036] In one embodiment, the display stand body 1 is a U-shaped structure, and the U-shaped structure is provided to facilitate the support arms 8 to be folded and stored for use.

[0037] In one embodiment, the inclined groove structure provided on the surface of the carrier plate 7 is the same as the arc-shaped structure at the bottom of the sphere. The structural setting of the groove on the surface of the carrier plate 7 is to facilitate the subsequent support and use of the sphere, thereby facilitating the subsequent picking and placing operations.

[0038] In one embodiment, the thickness of the gear plate 13 is greater than the depth of the limiting groove 12. The thickness of the gear plate 13 is set to ensure that the teeth arranged on its surface that mesh with the gear disk 10 can be exposed outside the limiting groove 12, thereby ensuring that it can be smoothly connected to the gear disk 10 and ensuring the normal use of subsequent structures.

[0039] Working principle: In actual use, the display stand body 1 can be moved to the area where the display operation is required through the lockable moving wheels 16, and then the gear plate 13 can be moved up along the limit groove 12 through the jacking operation of the hydraulic rod 15. At this time, the gear plate 13 will drive the gear plate 10 meshing with it to rotate, and the gear plate 10 will synchronously drive the support arm 8 on its surface to rotate. At this time, the support arm 8 can be adjusted from the folded horizontal state to the inclined state, and then the personnel can place the balls to be displayed at the top position of the support arm 8. At this time, the balls can be displayed. When the support arm 8 at a higher position is used, the personnel can first place the ball into the groove at the top of the loading plate 7, and the groove can be used to limit the ball. Then, the operation of the second brake motor 11 can drive the first screw 2 to rotate, and then the moving platform 3 can be lifted as a whole. When the moving platform 3 moves as a whole to the lateral position of the support arm 8 that is needed, the operation of the first brake motor 4 can drive the drive shaft 20 to rotate, and then the support plate 19 can be rotated as a whole. At this time, the support plate 19 can move to the lower position of the support arm 8. At this time, the operation of the third brake motor 17 and the gradual recovery of the electric push rod 5 can drive the loading plate 7 to move slowly toward the inside of the support arm 8 and gradually move downward. In this way, the ball can be gradually and slowly placed in the position between the support arms 8 to realize the placement operation, which is convenient for subsequent display and use. Similarly, when taking out the ball at a higher position, the above operation can be performed in reverse to realize the easy removal of the ball. There is no need for personnel to climb to the top position to operate, which improves the practicability of the device, reduces the risk of personnel operation, and is convenient for better use. The device as a whole has the advantages of convenient loading and unloading, labor-saving folding, and strong practicality.
