Abstract

The utility model discloses an eccentric wheel for wood board connection. In the technical proposal, the top part of an eccentric wheel is provided with a mounting hole; one side of the lower part of the eccentric wheel is provided with an accommodating chamber with an opening; the other side of the lower part of the eccentric wheel is eccentrically provided with a limit bayonet along the periphery; the inner side and the outer side of an upper limit block of the limit bayonet are both provided with anti-slip serrated teeth; the inner side of a lower limit block of the limit bayonet is provided with anti-slip serrated teeth; and the rotating speed of the limit bayonet from the opening end to the bayonet terminal is 225 degrees along the center of circle of the eccentric wheel. Compared with the prior art, the utility model has the advantages of stability, convenient installation, durability and high applicability.

Description

A kind of core shift wheel that is used for the plank connection

Technical field

The utility model relates to furniture and makes the field, is specifically related to a kind of core shift wheel that plank connects that is used for.

Background technique

In Modern Furniture Design, easy to assembly and the simple and easy design focal point that has become furniture, some plate fitments adopt screw rod to cooperate the core shift wheel to connect at present, on plate, get earlier mounting hole, one end of screw rod is fixedly mounted on the plank, the other end packs in the mounting hole of another piece plank, fixes by rotation core shift wheel, thereby reaches the purpose of fixedly connected two planks.

But also there is not enough point in existing core shift wheel: the furniture plate makes furniture loosening swag phenomenon occur through the tight plank of dismounting rear connectors lock twice or thrice; Core shift wheel in use occurs breaking and can not use, or to be out of shape appears when stressed in furniture, makes furniture pine occur and shakes phenomenon; Core shift wheel rotary lifting distance is little, and when the punching of furniture had error, the furniture interconnect function was stressed not on the optimum position; The installation of core shift wheel needs specific setting tool, can not install by general multiple instrument.

Summary of the invention

Basic purpose of the present utility model is to overcome the deficiencies in the prior art, provides a kind of can the cooperation with screw rod firmly to be connected plank, and the wheeled link of core shift that repeatedly also can not lose efficacy after the dismounting at plank, become flexible, and is called for short the core shift wheel.

The further purpose of the utility model is to make that this core shift wheel use is more convenient, especially can be fit to use multiple setting tool commonly used to install.

The technical solution of the utility model is as follows:

A kind of core shift wheel that is used for the plank connection, the top is provided with mounting hole, the bottom is the accommodating chamber that a side is provided with opening, opposite side is provided with spacing bayonet socket along the circumference core shift, it is characterized in that: the inside and outside both sides of the upper limit position block of described spacing bayonet socket are equipped with anti-skidding sawtooth tooth, and the lower position block inboard of spacing bayonet socket is provided with anti-skidding sawtooth tooth.

Further improve and be:

Described spacing bayonet socket is taken turns the center of circle from opening end to the bayonet socket end along core shift angle of swing is 225 degree.

Described mounting hole is the combined hole that is provided with one heart, comprises a cross bore, the compound regular polygon hole that is provided with in the centre of cross bore.

When the assembling plate fitment, the utility model cooperates screw rod to realize being connected between furniture-plates and the plate, the inside and outside both sides of upper limit position block that core shift of the present utility model is taken turns spacing bayonet socket are equipped with anti-skidding sawtooth tooth, the lower position block inboard of spacing bayonet socket is provided with anti-skidding sawtooth tooth, inner anti-skidding sawtooth tooth makes spacing fixture block and screw rod swelling be difficult for wraparound, outside anti-skidding sawtooth tooth makes core shift wheel swelling plank be difficult for wraparound, the limit swing of spacing bayonet socket is 225 degree by 180 degree liftings of general core shift wheel, be reserved with certain stretch range, guarantee that plank is through repeatedly still connecting firmly after the dismounting, also can guarantee when little deviation appears in the plank punching, still normal mounting to connect, mounting hole is fit to general setting tool and installs, as Allen key, Phillips screwdriver, straight screwdrivers etc. do not need special tool promptly can install.

Compared with prior art, the utility model has following advantage: connect firm, easy for installation, durable, applicability is strong.

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

Fig. 2 is the side view of Fig. 1;

Fig. 3 is the utility model angle of swing schematic representation;

Fig. 4 is that the utility model cooperates screw rod that connection plate schematic representation is installed.

Embodiment

As shown in Figure 1 and Figure 2, a kind of core shift wheel that is used for the plank connection, the top is provided with mounting hole 1, the bottom is the accommodating chamber that a side is provided with opening, opposite side is provided with spacing bayonet socket 2 along the circumference core shift, the upper limit position block 21 inside and outside both sides of spacing bayonet socket 2 are equipped with anti-skidding sawtooth tooth 3, and lower position block 22 inboards of spacing bayonet socket 2 are provided with anti-skidding sawtooth tooth 3.

As shown in Figure 3, the limit swing of spacing bayonet socket is 225 degree by 180 degree liftings of general core shift wheel, be reserved with certain stretch range, guarantee that plank through repeatedly still connecting firmly after the dismounting, also can guarantee still normal mounting to connect when little deviation appears in the plank punching.

As shown in Figure 4, when the assembling plate fitment, the utility model cooperates screw rod 4 to realize being connected between furniture-plates 5 and the plate 6, and the inner anti-skidding sawtooth tooth of core shift wheel makes spacing fixture block and screw rod 4 swellings be difficult for wraparound, and the anti-skidding sawtooth tooth 3 of outside makes core shift take turns swelling plank 6 to be difficult for wraparound.

Mounting hole 1 is the combined hole that is provided with one heart, comprise a cross bore, the compound regular hexagon hole that is provided with in the centre of cross bore is fit to general setting tool and installs, as Allen key 7, Phillips screwdriver 8, straight screwdriver 9 etc., do not need special tool promptly can install.

Claims
