Abstract
The invention discloses an eccentric wheel of a three-in-one connecting piece. The eccentric wheel of the three-in-one connecting piece sequentially comprises a rotating disk, a body wheel and a torsion bend from top to bottom. A main screw hole is engraved in the center of the rotating disk, skid-resistance teeth are arranged on the outer edge of the body wheel and the outer edge of the torsion bend, the center of the body wheel protrudes upwards to form a connecting rod cavity, the upper end of the connecting rod cavity is attached to the lower end of the rotating wheel, an auxiliary screw hole corresponding to the main screw hole in shape is formed in the middle of the connecting rod cavity, the rotating disk, the body wheel and the torsion bend are of an integrated structure, and the rotating disk, the body wheel and the torsion bend form an integrated structure through a first connecting wall and a second connecting wall. Because the eccentric wheel of the three-in-one connecting piece is of an integrated structure and is integrally formed, the strength is high, the eccentric wheel is not prone to breaking, the production efficiency is high, and cost is low.
Description
Technical field
The present invention relates to a kind of furniture assembly link, be specifically related to a kind of eccentric wheel of three-in-one link.
Background technique
Three-in-one link is also known as fastening piece or combiner, generally be made up of eccentric wheel, connecting rod and anti-skidding pre-smooth sizing material, be mainly used in the link of plate fitment, particularly plate fitment plate is connected with vertical between plate or three plates connect alternately, do not need screw can realize the level connection joint of two plates, be generally used for medium-density plate, high-density plate, shaving board.Wherein eccentric wheel is central most important connection fittings, the radian of the stray circle specifically utilizing torsion bent angle bottom the eccentric wheel heart in the heart, when being rotated eccentric plus screw groove by gimlet, the connecting rod be stuck in radian can pull to eccentric center along radian, thus make connecting rod strain distance between eccentric wheel and anti-skidding pre-smooth micelle, thus make to be connected between plate with plate firm.This three-in-one link greatly facilitates the transport of furniture, on-sites install, and has also carried forward vigorously the industrialized production of overall furniture and integral cabinet.Along with the application of this link is more and more wider, the use amount of three-in-one link increases day by day, because eccentric wheel is most important and the part that structure is the most complicated again, the control therefore how improving eccentric manufacturing efficiency and cost of production becomes an important problem.
The patent No. is the eccentric wheel that patent discloses a kind of three-in-one link of 201320610659.X, the riser that passes on left of wherein said rotating disk, body wheel and torsion bent angle links into an integrated entity, be separable structure between body wheel and riser, need assemble when therefore manufacturing a finished product, waste time and energy, thus have impact on manufacture efficiency and cost of production.And gimlet is when rotating eccentric cross recess, drive eccentric body to take turns by connecting rod and rotate, the moment of torsion born due to eccentric wheel is large and uneven, is easy to cause eccentric wheel to rupture.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of eccentric wheel of three-in-one link, and integral structure is one-body molded, and intensity is good, and not easily cause eccentric wheel to rupture, and manufacturing efficiency is high, cost is low.
The technological scheme that technical solution problem of the present invention adopts is: a kind of eccentric wheel of three-in-one link, comprise rotating disk successively from top to bottom, body wheel and torsion bent angle, main screw hole is carved with in the middle of described rotating disk, the outer of described body wheel and torsion bent angle is equipped with slideproof tooth, described body wheel middle formation connecting rod protruding upward cavity volume, fit in the upper end of described connecting rod cavity volume and the lower end of rotating disk, and the middle of connecting rod cavity volume has the secondary screw hole corresponding with main screw hole shape, it is characterized in that: described rotating disk, body wheel and torsion bent angle are integral type structure, described rotating disk, integral structure is realized by connecting wall I and connecting wall II between body wheel and torsion bent angle.
As further improvement, described rotating disk is taken turns with body end of fitting and is provided with fixing column.
The present invention adopts cold rolled steel, once shaping on accurate punching machine by integral type progressive die.Fixing column of the present invention is by pressure hole forming, end of first fitting with rotating disk on body wheel is provided with a through hole, pressure hole is carried out in through hole again on rotating disk on corresponding body wheel, the through hole that the part of pressure is taken turns with body mates fixing, form fixing column, when gimlet rotates eccentric cross recess, fixing column plays twisting resistance effect, makes eccentric wheel not easily cause fracture.
The invention has the beneficial effects as follows: adopt integral structure one-body molded, intensity is good, and manufacturing efficiency is high, reduces manpower, reduces costs; Take turns at rotating disk and body end of fitting and be provided with fixing column, make eccentric wheel not easily cause fracture.

Fig. 1 is the stereogram one of the embodiment of the present invention.
Fig. 2 is the stereogram two of the embodiment of the present invention.
Fig. 3 is the side view of the embodiment of the present invention.
Below in conjunction with accompanying drawing, the present invention will be further described.
Embodiment
As shown in Figure 1, a kind of eccentric wheel of three-in-one link, comprise rotating disk 1 successively from top to bottom, body wheel 2 and torsion bent angle 3, described rotating disk 1, body wheel 2 and torsion bent angle 3 are integral type structure, main screw hole 7 is carved with in the middle of rotating disk 1, the outer of described body wheel 2 and torsion bent angle 3 is equipped with slideproof tooth 4, described body takes turns 2 middle formation connecting rod protruding upward cavity volumes, fit in the upper end of described connecting rod cavity volume and the lower end of rotating disk 1, and the middle of connecting rod cavity volume has the secondary screw hole corresponding with main screw hole 4 shape, described rotating disk 1, integral structure is realized by connecting wall I 5 and connecting wall II 6 between body wheel 2 and torsion bent angle 3.Described rotating disk 1 is taken turns with body 2 ends of fitting and is provided with fixing column 8.
