The utility model has the advantages that: structural design is reasonable, has replaced the support rotation function of bearing, has certain practicality and functional in the technique, and has solved among the prior art and directly placed the disc and can't realize pivoted problem on the display stand, for the trade company provides convenience, convenience of customers carries out nimble equipment and the function of conveniently holding.

Description

Rotating mechanism capable of replacing bearing

Technical Field

The utility model relates to the field of rotating mechanisms, in particular to a rotating mechanism capable of replacing a bearing.

Background

In the prior art, the disc-shaped fireworks are generally connected to a chassis by adopting a bearing structure in the process of setting off production, so that the fireworks body is driven to rotate by the sprayed fireworks during setting off, but the bearing structure for connecting the fireworks has the defects of complex chassis manufacturing process, complex connection in the implementation process, high manufacturing cost because the fireworks are required to be penetrated in the bearing by a connecting rod after being fixed, and the fireworks cannot be flexibly moved due to the defects of high manufacturing cost and the defect of inconvenience for merchants.

Therefore, a rotating mechanism capable of rotatably penetrating fireworks and capable of replacing bearings is to be proposed.

Disclosure of Invention

Aiming at the problems, the utility model provides a device capable of conveniently realizing rotary connection with a firework fixing mechanism.

The technical scheme provided by the utility model is as follows: the utility model provides a rotation mechanism that can replace bearing to use, includes base and movable rotation piece of wearing to establish on the base, the base forms the notch from its up end undercut, rotation piece comprises top-down handle, disk, center pillar and expansion knot, the expansion knot quantity is two, the expansion knot is elastic material, and the expansion knot comprises knot stem and knot head, and the external diameter that two knot stems formed is less than the internal diameter of notch, and the external diameter that two knot heads formed is greater than the internal diameter of notch.

As a preferable scheme, the sum of the lengths of the middle column and the buckling stem is slightly larger than the length of the notch.

Compared with the prior art, the utility model has the advantages that: structural design is reasonable, has replaced the support rotation function of bearing, has certain practicality and functionality in the technique, and has solved convenient rotation fireworks, reduces cost of manufacture's problem, provides convenience for the trade company, conveniently carries out nimble equipment and conveniently grips the function.

Drawings

FIG. 1 is an exploded view of the present utility model;

fig. 2 is a schematic structural view of the present utility model.

Detailed Description

The utility model is described in further detail below with reference to fig. 1-2.

The utility model provides a rotary mechanism that can replace bearing to use, includes base 1 and movable rotation piece 2 of wearing to establish on base 1, base 1 forms notch 3 from its up end undercut, rotation piece 2 comprises top-down handle 4, disk 5, center pillar 6 and expansion buckle 7, expansion buckle 7 figure is two, expansion buckle 7 is elastic material, and expansion buckle 7 comprises knot stem 8 and button head 9, and the external diameter that two knot stems 8 formed is less than the internal diameter of notch 3, and the external diameter that two button heads 9 formed is greater than the internal diameter of notch 3.

As a preferred solution, the sum of the lengths of the stem 6 and the stem 8 is slightly greater than the length of the recess 3.

In the implementation of the utility model, the buckling head of the expansion buckle of the rotating member is pressed inwards, the expansion buckle of the rotating member is plugged into the notch, so that the buckling head clamps the lower edge of the notch, as shown in figure 2, the rotating member can freely rotate in the notch, a bearing is replaced, the disassembly is convenient, and the cost is reduced.

The utility model and its embodiments have been described above with no limitation, and the actual construction is not limited to the embodiments of the utility model as shown in the drawings. In summary, if one of ordinary skill in the art is informed by this disclosure, a structural manner and an embodiment similar to the technical solution should not be creatively devised without departing from the gist of the present utility model.
