The number of expansion buckles is two. The expansion buckles are made of elastic material. The expansion buckles are composed of buckle stems and buckle heads. The outer diameter formed by the two buckle stems is less than The inner diameter of the notch, the outer diameter formed by the two buckles is greater than the inner diameter of the notch, and the sum of the lengths of the center column and the buckle stem is slightly greater than the length of the notch. The advantage of this utility model is that it has a reasonable structural design, replaces the supporting and rotating function of the bearing, has certain technical practicability and functionality, and solves the problem in the prior art that the disc cannot be rotated directly by being placed on the display stand. problem, it provides convenience for merchants, convenient for users to flexibly assemble and hold functions.

Description

A rotating mechanism that can replace bearings

Technical field

The utility model relates to the field of rotating mechanisms, and specifically refers to a rotating mechanism that can replace bearings.

Background technique

In the prior art, disc-shaped fireworks are generally connected to a chassis using a bearing structure during the discharge and production process, so that the sprayed fireworks drive the fireworks body to rotate when they are discharged. However, the disadvantage of this structure is that it is used to connect the fireworks. The manufacturing process of the bearing structure, including the chassis, is complicated, and the shortcoming during the implementation process is that the connection is complicated. After the fireworks are fixed, a connecting rod needs to be inserted into the bearing to facilitate the rotation of the fireworks. The production cost is high, and it must be combined with the fireworks. Another disadvantage in the fixation process is that it cannot achieve flexible movement, which brings inconvenience to the merchants.

Therefore, a rotating mechanism that can replace the bearing and can rotate the fireworks needs to be proposed.

Utility model content

In view of the above problems, the present utility model proposes a device that can facilitate rotational connection with the fireworks fixing mechanism.

The technical solution provided by the utility model is: a rotating mechanism that can replace a bearing, including a base and a rotating member that can be movably installed on the base. The base is recessed downward from its upper end to form a notch, and the rotating member It consists of a top-down handle, a disc, a center column and an expansion buckle. The number of the expansion buckles is two. The expansion buckles are made of elastic material. The expansion buckles are composed of a buckle stem and a buckle head. The two buckle stems form The outer diameter of the buckle is smaller than the inner diameter of the notch, and the outer diameter formed by the two buckles is larger than the inner diameter of the notch.

As a preferred solution, the sum of the lengths of the central column and the buckle stem is slightly greater than the length of the notch.

Compared with the existing technology, the advantages of this utility model are: reasonable structural design, replacing the supporting and rotating function of the bearing, having certain technical practicability and functionality, and solving the problem of conveniently rotating fireworks and reducing production costs. It provides merchants with convenience, flexible assembly and easy-to-hold functions.

Description of the drawings

Figure 1 is an exploded view of the utility model;

Figure 2 is a schematic structural diagram of the utility model.

Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings 1-2.

A rotating mechanism that can replace a bearing, including a base 1 and a rotating member 2 that can be movably installed on the base 1. The base 1 is recessed downward from its upper end to form a notch 3. The rotating member 2 is formed from top to bottom. The lower handle 4, disc 5, center column 6 and expansion buckle 7 are composed of two expansion buckles 7. The expansion buckles 7 are made of elastic material. The expansion buckles 7 are composed of a buckle stem 8 and a buckle head 9. , the outer diameter formed by the two buckle stems 8 is smaller than the inner diameter of the notch 3, and the outer diameter formed by the two buckle heads 9 is larger than the inner diameter of the notch 3.

As a preferred solution, the sum of the lengths of the central column 6 and the buckle stem 8 is slightly larger than the length of the notch 3 .

When the utility model is implemented, press the buckle head of the expansion buckle of the rotating part inward, and stuff the expansion buckle of the rotating part into the notch, so that the buckle head catches the lower edge of the notch, as shown in Figure 2, so that the rotation The parts can rotate freely in the notches, replacing bearings, making disassembly easier and reducing costs.

The present utility model and its embodiments have been described above. This description is not limiting. What is shown in the drawings is only one embodiment of the utility model, and the actual structure is not limited thereto. In short, if a person of ordinary skill in the art is inspired by it and without departing from the creative purpose of the present utility model, can design a similar structural method and embodiment to the technical solution without creativity, they shall all fall under the protection of the present utility model. scope.
