[0029] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0030] like Figure 1 to Figure 2 As shown, the gear storage support base described in the utility model includes two groups of symmetrically arranged support bodies 1, and a synchronous opening and closing mechanism 2 is provided at the opposite end faces of the two groups of support bodies 1. The synchronous opening and closing mechanism 2 includes two groups of meshing half gears 3 and a connecting plate 4, and the two ends of the connecting plate 4 are respectively hingedly connected to the half gear 3 through the half gear shaft 5 of the half gear 3.

[0031] The synchronous opening and closing mechanism 2 also includes two groups of symmetrically arranged half gear connecting parts 6, the opposite ends of the two groups of half gear connecting parts 6 are meshed and connected through two groups of half gears 3, and the other ends of the two groups of half gear connecting parts 6 are respectively connected to the support body 1. Of course, the half gear connecting parts 6 can also be integrally formed with the support body 1.

[0032] like Figure 3 As shown, the two sides where the half gear connecting part 6 and the supporting body 1 are connected have folding locking parts 61. When the supporting body 1 is in a supporting state, that is, the two groups of supporting bodies 1 are symmetrical and on the same straight line, after the two groups of supporting bodies 1 rotate 90° along the half gear 3 under the action of external force, the folding locking parts 61 abut and fit each other. At this time, the two groups of supporting bodies 1 are in a folded and stored state, that is, the two groups of supporting bodies 1 are in a parallel state.

[0033] The storage support base can be unfolded or folded by pushing the support body 1. Due to the hinged connection between the connecting plate 4 and the meshing half gear 3, the meshing half gear 3 rotates smoothly, avoiding slipping and idle travel of the storage support base during the unfolding or folding process.

[0034] In this embodiment, the half gear connecting part 6 is fixedly connected to the support body 1 by screws. Specifically, the end of the support body 1 that is connected to the half gear connecting part 6 has a support sheet 11, and the support sheet 11 extends outward from the end surface of the support body 1, and the support sheet 11 and the support body 1 are in a stepped structure. The half gear connecting part 6 is arranged on the support sheet 11. Specifically, the lower end surface of the half gear connecting part 6 has a contoured groove 7 corresponding to the support sheet 11, and the half gear connecting part 6 and the support sheet 11 have corresponding screw holes 8, and the half gear connecting part 6 is screwed to the support sheet 11 through the screw holes 8.

[0035] In this embodiment, there are three groups of screw holes 8, and the center points of the three groups of screw holes 8 are connected to form a triangle. The half gear connecting part 6 is fixed to the supporting plate 11 through screws and the three groups of screw holes 8. The stability of the triangle makes the fixation more secure.

[0036] Furthermore, the upper end surface of the half gear connecting portion 6 and the upper end surface of the supporting body 1 are located in the same plane.

[0037] In this embodiment, Figure 4 As shown, the gear teeth of the half gear 3 are arranged on one-fourth of the root circle, that is, the end faces of the two groups of half gear connecting parts 6 connected to each other include meshing spur gear parts 31 and contacting plane parts 62. When the two groups of support bodies 1 are in a supporting state, the two groups of plane parts 62 are contacted. The spur gear part 31 extends along the root circle circumference to the corresponding side surfaces of the two groups of half gear connecting parts 6 to form a side gear tooth part 32. The side gear tooth part 32 is connected to the folding locking part 61. In this embodiment, the half gear 3 and the half gear connecting part 6 are integrally formed. This structure allows the storage support base to be folded and stored only along one side of the support body 1, and the plane part 62 ensures that the two groups of support bodies 1 are in the same straight line when unfolded to prevent the unfolding angle from being too large to affect the support effect.

[0038] Furthermore, the contoured groove 7 has a semicircular recess 71 which is concentric with the tooth root circle and a square recess 72 which is connected to the semicircular recess 71. The support plate 11 is accommodated in the contoured groove 7. One of the three groups of screw holes 8 is located in the semicircular recess 71, and the other two groups of screw holes 8 are located in the square recess 72. Through proper arrangement, the center point connection line of the three groups of screw holes 8 can form a maximized triangle, so that the fixation of the half gear connecting part 6 and the support plate 11 is more stable.

[0039] In this embodiment, the structure is suitable for various display occasions. When the user needs to fold the support base, he only needs to apply a corresponding force to each support body 1. Through the cooperation between the support body and the half gear, the support base can be smoothly folded under the display product body to complete the folding and storage. Similarly, when unfolding the support base, the user only needs to apply a reverse thrust to each support body 1, and the support body 1 can be quickly unfolded, so that the support base returns to a stable support state. The mechanism can be easily unfolded and folded for storage, is very convenient to use, and does not take up extra space.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
