Abstract

The utility model discloses a carousel steel ball holder. Current carousel steel ball holder installation steel ball is inconvenient, and the structural instability, and it is unreliable to use. The utility model discloses an outer lane, arrange outer lane inboard inner circle and a plurality of steel ball that is located between the inside and outside circle in, inner circle and outer lane between be equipped with a plastic cage who is used for fixed a plurality of steel balls, plastic cage a plurality of bayonet sockets that are used for card income steel ball of including annular plastics support body and forming on annular plastics support body, the opening of bayonet socket down, the steel ball arrange the bayonet socket in. The utility model discloses simple to operate, stable in structure uses reliably.

Description

Rotating disk steel ball keeps frame

Technical field

The utility model relates to dining table, furniture rotating disk, and specifically a kind of rotating disk steel ball keeps frame.

Background technology

Tradition dining table, furniture rotating disk are generally made up of outer ring and the inner ring that is placed in outer ring, the inner side-wall of outer ring forms a circle inner groove, the outer side wall of inner ring forms a circle outer groove, many steel balls it are provided with between outer groove and inner groove, colliding between steel ball when this kind of structure is rotated, noise is bigger.

For this reason, the steel ball that most of employing is sandwiched between inner ring and outer ring at present keeps frame to install steel ball, avoids and collides between steel ball, and during rotation, noise is low, but existing steel ball keeps frame to install steel ball inconvenience, and structure instability, it may also be useful to unreliable.

Practical novel content

Technical problem to be solved in the utility model overcomes the deficiency that above-mentioned prior art exists, it is provided that a kind of steel ball is easy for installation, Stability Analysis of Structures and use reliable rotating disk steel ball to keep frame.

For this reason, the technical solution adopted in the utility model is as follows: rotating disk steel ball keeps frame, comprise outer ring, it be placed in the inner ring inside outer ring and multiple steel ball between inside and outside circle, be provided with one between described inner ring and outer ring for fixing the plastic cage of multiple steel ball;

Multiple bayonet sockets entering steel ball for card that described plastic cage comprises annular plastics frame body and formed on annular plastics frame body, bayonet socket opening down, described steel ball is placed in bayonet socket.

The utility model utilizes plastics to have certain elastic feature, makes bayonet socket that less elastic deformation occurs when installing steel ball, and steel ball enters after in bayonet socket, and bayonet socket Rapid reset, is stuck in steel ball on annular plastics frame body.

Further, the inner side-wall of described outer ring forms a circle inner groove, and the outer side wall of inner ring forms a circle outer groove; The middle part of steel ball is placed in bayonet socket, and a sidepiece is placed in inner groove, and the other side is placed in outer groove.

Further, the top of described bayonet socket is major arc, and bottom is splayed, and the lower end of major arc is connected with the upper end transition of splayed. Adopt the bayonet socket of this structure, make that the installation of steel ball is more convenient, structure is more stable.

Further, it is positioned on the annular plastics frame body of bayonet socket both sides and all has the gap that is beneficial to bayonet socket deformation; The upper end closed in gap, lower ending opening. Gap is bayonet socket offer deformation space.

Further, it is positioned at the annular plastics frame body end face directly over gap and has the breach being beneficial to bayonet socket deformation.

The useful effect that the utility model has is as follows: easy for installation, Stability Analysis of Structures, it may also be useful to reliable; Rotating flexibly when the utility model makes rotating disk use, noise is low.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the partial enlargement figure of the utility model plastic cage.

In figure, 1-outer ring, 2-inner ring, 3-steel ball, 4-plastic cage, 41-annular plastics frame body, 42-bayonet socket, 43-gap, 44-breach.

Embodiment

Rotating disk steel ball as shown in the figure keeps frame, and inner ring 2 is placed in inside outer ring 1, and multiple steel ball 3, between inside and outside circle, is provided with the plastic cage 4 for fixing multiple steel ball 3 between described inner ring 2 and outer ring 1.

Described plastic cage 4 is made up of annular plastics frame body 41 and multiple bayonet sockets 42 entering steel ball 3 for card of being formed on annular plastics frame body 41, bayonet socket 42 opening down. The inner side-wall of outer ring 1 forms a circle inner groove, and the outer side wall of inner ring 2 forms a circle outer groove; The middle part of steel ball 3 is placed in bayonet socket 42, and a sidepiece is placed in inner groove, and the other side is placed in outer groove.

The top of described bayonet socket 42 is major arc, and bottom is splayed, and the lower end of major arc is connected with the upper end transition of splayed. It is positioned on the annular plastics frame body 41 of bayonet socket 42 both sides and all has the gap 43 that is beneficial to bayonet socket 42 deformation; The upper end closed in gap 43, lower ending opening. It is positioned at annular plastics frame body 41 end face directly over gap 43 and has the breach 44 being beneficial to bayonet socket 42 deformation.

Preferred forms of the present utility model is described in detail with reference to the attached drawings out, and those skilled in the art can modify and conversion according to the technical program, and such amendment all should be included within scope of patent protection of the present utility model with conversion.
