Abstract
The furniture connecting piece consists of a connecting pin and two identical expansion bolts, wherein the expansion bolts are of hollow structures with openings at two ends, and two ends of the connecting pin respectively enter inner holes of the expansion bolts from inlet ends of the expansion bolts to connect the two expansion bolts together. The invention connects two expansion bolts installed in the wood boards through a connecting pin, thereby realizing the connection of two adjacent wood boards.
Description
Technical field
The present invention relates to a kind of furniture link that furniture link, particularly plate fitment are installed and used that is used for, belong to the optimisation technique that furniture is installed.
Background technique
Three-in-one link or four unification links are mainly used in the installation of present furniture, particularly plate fitment.
Three-in-one link, advantage are that parts are few, sound construction, and shortcoming mainly contains 2 points: when one, installing, need to install a large amount of screw rods, processing has certain tolerance usually, often needs artificial height to screw rod to carry out leveling, cooperates with eccentric to satisfy; Two, because eccentric wheel is to adopt alloy to make mostly, and often intensity is relatively poor, situation about in practical application, often fracturing and deforming needs taking-up to change again relatively difficulty.
Four unification links, advantage are that parts are few, installation is simple, can realize that the parts after the random general assembly are arbitrarily changed, and shortcoming is: requirement on machining accuracy is higher, and difficulty of processing is bigger.
Therefore, it is simpler need to seek a kind of structure, parts still less, installs faster simply, the manufacturing procedure of furniture still less, the lower furniture link of required precision.
Summary of the invention
It is simpler to the purpose of this invention is to provide a kind of structure, parts still less, install faster simple, the manufacturing procedure of furniture still less, the lower furniture link of required precision.
Technological scheme of the present invention is: a kind of furniture link; Form with two identical expansion bolts 2 by a connecting pin 1; Described expansion bolt 2 adopts the hollow structure of both ends open; The two ends of described connecting pin 1 get into the endoporus of expansion bolt 2 respectively from the entry end 21 of expansion bolt 2, two expansion bolts 2 are linked together.
Described connecting pin 1 is the cylindrical body of middle part diameter greater than the two ends diameter, and the middle part is a limited post 11, and two ends are fixing column 12, on the wall of fixing column 12, is provided with an annular groove coaxial with it 13.
The end of described fixing column 12 is provided with chamfering.
Described annular groove 13 is the plane vertical with the medial axis of fixing column 12 near the terminal sides of fixing column 12, and other partly is the conical surface with this Plane intersects.
The outer wall construction negative and positive symmetry of the interior wall construction of described expansion bolt 2 and fixing pin 1.
The wall of described expansion bolt 2 is provided with plural expansion hatch 22.
The outer wall of described expansion bolt 2 is provided with more than one the annular projection 23 coaxial with expansion bolt 2.
Described annular projection 23 is a dentation, and is vertical with the medial axis of expansion bolt 2 towards the side of expansion bolt 2 entry ends 21.
The invention has the beneficial effects as follows:
1, through a connecting pin two expansion bolts that are installed in the plank is coupled together, realize two adjacent planks are linked together.
2, on connecting pin, be provided with annular groove and limited post, the inner endoporus that adopts the yin-yang structure identical with the connecting pin external structure of expansion bolt makes both connections more fastening.
Description of drawings
Fig. 1 is the cross-sectional view of the actual use of the present invention;
Fig. 2 is the structural representation of connecting pin of the present invention;
Fig. 3 is the sectional structure schematic representation of expansion bolt of the present invention.
Embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3; A kind of furniture link; Form with two identical expansion bolts 2 by a connecting pin 1; Described expansion bolt 2 adopts the hollow structure of both ends open, and the two ends of described connecting pin 1 get into the endoporus of expansion bolt 2 respectively from the entry end 21 of expansion bolt 2, two expansion bolts 2 are linked together.Before the installation, open the expansion bolt mounting hole in the relevant position of adjacent plank earlier, expansion bolt 2 is knocked in the mounting hole of holding successfully, knock in an end of connecting pin 1 in the endoporus of an expansion bolt 2; Again the endoporus of the expansion bolt 2 on another piece plank is aimed at the other end of connecting pin 1, utilized external force that connecting pin is got in the endoporus of expansion bolt 2, thereby two expansion bolts 2 are linked together, simultaneously two adjacent planks also closely are fixed together.
Described connecting pin 1 is the cylindrical body of middle part diameter greater than the two ends diameter, and the middle part is a limited post 11, and two ends are fixing column 12, on the wall of fixing column 12, is provided with an annular groove coaxial with it 13.The shape of cross section of described annular groove 13 can be shapes such as square, semicircle, zigzag fashion.Preferred version is described annular groove 13 near fixing column 12 terminal sides is the plane vertical with the medial axis of fixing column 12, and other partly is the conical surface with this Plane intersects.
The preferred version of the end of described fixing column 12 is that chamfering is set, so that fixing column 12 plays the effect of guiding when getting into expansion bolt 2.
The outer wall construction negative and positive of the interior wall construction of described expansion bolt 2 and connecting pin 1 symmetry, make connecting pin 1 get into expansion bolt 2 after, both just can closely cooperate, if at the end of fixing column 12 chamfering is set, can produce space in a small amount between the two.
The wall of described expansion bolt 2 is provided with plural expansion hatch 22.Usually; Connecting pin 1 adopts interference fit with being connected of expansion bolt 2; Plus tolerance is adopted in the processing that is connecting pin 1; And the inwall processing dimension of expansion bolt 2 adopts negative common difference, makes connecting pin 1 could get into expansion bolt 2 by the effect and the dilating expansion mouth 22 of external force, thereby makes cooperation between the two tight.In addition; Annular groove 13 forms interlock with the relevant position of expansion bolt 2, furniture move or using process in receive the external force effect, if external force attempts from expansion bolt 2, to pull out connecting pin 1; Will produce a reverse resistance; Stop connecting pin 1 from expansion bolt 2, to be drawn out, therefore, such connection is more firm.
The outer wall of described expansion bolt 2 is provided with more than one the annular projection 23 coaxial with expansion bolt 2.
Described annular projection 23 is a dentation, and is vertical with the medial axis of expansion bolt 2 towards the side of expansion bolt 2 entry ends 21.The effect of annular projection 23 is similar with the effect of annular groove 13, and when throwing expansion bolt 2 in the perforate on the plank into, the annular projection 23 on the expansion bolt 2 plays the effect of a backward hold plank; And; After connecting pin 1 was squeezed into expansion bolt 2, the further dilating expansion bolt 2 of meeting made annular projection 23 deeper embed the hole wall of plank; To from the perforate of plank, pull out expansion bolt 2 as external force; Need overcome the interlock resistance that forms between annular projection 23 and the plank, therefore, such connection is very firm.
The foregoing description only is to be used for interpretation purposes of the present invention, and is not to be limitation of the present invention, and those skilled in the art in essential scope of the present invention, make various variations or alternative, also should belong to protection category of the present invention.
