Description

A kind of rolling ring

Technical field

The utility model relates to a kind of rolling ring, is mainly used on sofa accessory, the swivel chair.

Background technology

In function sofa field, rotating sofa is a kind of application form the most widely, rotates sofa in the market and generally adopts dual mode: 1, and connect sofa main body and base through turning cylinder, thereby realize that sofa rotates; 2, connect the sofa main body through the rotating disk circle, roll in the disk track through steel ball in the rotating disk circle, realize the rotating function of sofa.Rotate sofa and can select its concrete rotation mode according to the requirement of actual style.

There is following defective in existing rotating disk circle:

1, since in the rotating disk ball orbit radius limited, and the influence of factor such as ball is yielding, the holding capacity of rotating disk circle is less relatively;

2, because it rotates mainly is to lean on the steel ball scrolling realization, and steel ball is in rotating disk in the rolling process, between the ball, between ball and the rotating disk, can produce collision unavoidably, so have noise when rotating;

3, the rotating disk circle is the fixing sofa body in position, hole through disk upper surface, because cost and technology considers, so this position, hole installation dimension is non-adjustable, and generally can be very not big, when making the rotation sofa, size is more restricted.

Summary of the invention

The utility model technical problem to be solved provides a kind of simple for structure, holding capacity is bigger, noise is little, the scope of application is big rolling ring.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this rolling ring comprises and turn-takes, connects support that turn-taking and being connected support is fixedly connected; Turn-take, connect the center fixation rotating shaft of support, it is characterized in that also being provided with travel(l)ing rest, telescope support, locking device, foot pad, bearing, the upper surface of turn-taking is provided with the roller track of bearing; Travel(l)ing rest is installed in the rotating shaft; Travel(l)ing rest two ends rigid bearing, bearing place on the roller track of the upper surface of turn-taking, and are with telescope support in the travel(l)ing rest; The telescope support two ends are fixed with L shaped installation sheet, through the fixing position of telescope support on travel(l)ing rest of locking device.

The said travel(l)ing rest of the utility model is two.

The said employing elliptical tube of turn-taking of the utility model.

The said locking device of the utility model is a screw.

The utility model through to rotating manner improvement, thereby has overcome the existing shortcoming of rotating disk circle on existing rotating disk cycle basis plinth, it has following advantage:

1, owing to the change of rotating manner, the holding capacity of rotating disk circle can more strengthen, and installation dimension is also bigger, can make larger sized rotation sofa;

2, because its rotating manner mainly relies on the scrolling realization of encapsulate bearing, eliminated the noise that produces in the rotation process basically;

3, adopt the telescope support structure, made the installation dimension of rotating disk to regulate as required.

Fig. 2 is the schematic top plan view of the utility model embodiment.

Fig. 3 is side-looking (rotation) figure of the utility model embodiment.

The specific embodiment

Referring to Fig. 1～Fig. 3; The utility model embodiment rolling ring; Comprise and turn-take 1, connect support 2, travel(l)ing rest 3, telescope support 4, rotating shaft 5, locking device 6, foot pad 7, bearing 8, the fixedly foot pad 7 of 1 lower surface of turn-taking, the roller track of 1 upper surface of turn-taking as the bearing 8 of encapsulate; Turn-taking 1 is fixedly connected with being connected support 2, turn-takes 1, connects the center fixation rotating shaft 5 of support 2, and travel(l)ing rest 3 is installed in the rotating shaft 5 around the shaft that 5 centers rotate freely; Travel(l)ing rest 3 two ends rigid bearings 8, bearing 8 outer ring encapsulates, and along with travel(l)ing rest 3 rotations are freely rolled at 1 upper surface of turn-taking; Be with telescope support 4 in the travel(l)ing rest 3, telescope support 4 two ends are welded with L shaped installation sheet, when reality is used, can realize the variation of installation dimension through regulating the position of telescope support 4; After confirming good position, the locking device 6 (screw) on the locking travel(l)ing rest 3 is fixed the installation site.

The utility model is turn-taked and 1 is adopted elliptical tube (turn-take 1 cross section for oval); Wherein turn-take 1 upper surface and lower surface is parallel surface; Because the contact-making surface that encapsulate bearing 8 rolls is exactly the upper surface of elliptical tube, can make bearing 8 bigger like this with the contact-making surface of elliptical tube, be more conducive to encapsulate bearing 8 in rolling process; Steadily, smooth and easy, simultaneously can make elliptical tube stressed more even.

The utility model is not limited to above-mentioned preferred embodiment, and simple deformation of the utility model or equivalent transformation should belong to the scope of the utility model protection.

Claims (3)
