Abstract
The utility model discloses a plate material U-shaped washer connecting buckle which solves the problem that the connection of a three-in-one buckle of a screw rod is not firm, and also solves the disadvantage that the opening of a crescent type screw rod with a washer is large. The connecting buckle comprises a screw rod and a washer, a screw neck of which the diameter is smaller than that of the middle screw body is arranged at the upper part of the screw rod; an opening matching with the diameter of the screw neck is arranged on the washer, to enable the washer to present a U-shaped structure, and the washer is clipped at the screw neck through the opening. The connection of the utility model adopts a bolt method, and the structure is stable; because the U-shaped washer is adopted, and the washer is directly inserted into the screw neck from the external, compared with the method that the screw rod is penetrated from the middle, the opening is smaller, the object is small, to reach the purpose that the connection is invisible, and the outer appearance is artistic. Because the opening is smaller, the utility model is identical with the opening of the common three-in-one buckle, and the utility model can directly replace the three-in-one buckle.
Description
Technical field:
The utility model relates to a kind of link, especially a kind of sheet material " U " type pad connection fastener that is applicable to the Furniture panel connection.
Background technique:
At present, transportation is convenient in order to make furniture in furniture manufacturer, and is convenient to installing/dismounting, adopts screw rod, three-in-one fastener and " crescent moon " type pad screw rod as connection fastener mostly.These two kinds of connection fasteners all have certain defective.The three-in-one fastener of screw rod has to be installed fast, the characteristics of beautiful shape (having only a screw terminal) at furniture surface, but little with this connection fastener force bearing point, the furniture soundness of assembling is poor, working life is short, and is unable to undergo to move, and generally moves 1 and will be damaged for twice; The screw rod connection fastener is made of a screw rod, pad, nut, screw rod connects the two boards material, a hole has dug in the surface in the pad place, screw rod passes pad from sheet material inside, use nut tightening again, this structure is because pad is to be enclosed within on the screw rod, and therefore the hole that digs out is bigger, and one not attractive in appearance two also influences the ability of sheet material bearing load.
Summary of the invention:
This novel practical is intended to the characteristics in conjunction with above-mentioned two kinds of connection fasteners, and overcome the problem of its existence, and a kind of sheet material " U " type pad connection fastener is provided, both solve the three-in-one fastener of screw rod and connected not firm problem, solved crescent moon again " the big drawback of type pad screw rod perforate.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of sheet material " U " type pad connection fastener comprises screw rod, pad, and it is characterized in that: screw rod top has the spiral shell neck of one section diameter less than middle part spiral shell body; Pad be provided with one with the opening of spiral shell neck diameter coupling, make pad be " U " type structure, described pad is enclosed within Luo Jingchu through open card.
Described screw rod spiral shell neck top is nut.
Described screw rod spiral shell neck top is nut.
Described spiral shell body bottom is provided with the screw section, and is threaded with embedded nut.
Described spiral shell body bottom is provided with the screw section, this screw Duan Chengshen wood flute profile.
Described pad rear surface is a circular arc, and is suitable with the hole wall that digs out on the sheet material.
The mouth end of described opening and the shape of spiral shell neck are suitable.
Advantage of the present utility model is:
One, the bolt mode connects, and structure is firm;
Two, owing to adopt filling pad, pad directly inserts the spiral shell neck from the outside, and card is compared from the mode that the pad middle part penetrates with screw rod thereon, and perforate is little, and object is little, reaches stealthy and connects beautiful shape.
Three, because perforate is less, can be consistent with at present comparatively common three-in-one fastener perforate, can directly replace three and close fastener.

Embodiment
What this novel practical proposed is a kind of sheet material " U " type pad connection fastener, is particularly useful for the connection of Furniture panel.
This connection fastener belongs to the T-shape connection in the sheet material connection, this part is formed (as Fig. 1) by screw rod, pad 5.Screw-rod structure is made up of nut (also can adopt nut) 1, spiral shell neck 4, spiral shell body 2, screw 3, pad 5 be provided with one with the opening 6 of spiral shell neck diameter coupling, make pad 5 be " U " type structure, described pad 5 is fastened in spiral shell neck 4 places through opening 6.
During installation, perforate on the two boards material as shown in Figure 1, screw rod penetrates from sheet material A inside, up to handle hole 7.Pad 5 is inserted from handle hole 7, be fastened on the spiral shell neck 4 through opening 6.Screw rod lower end and sheet material B are connected with dual mode, and the one, on the corresponding sheet material B of screw rod, embedded nut 8 is set, by the nut on the rotary screw screw 3 on the screw rod is threaded with embedded nut; The 2nd, the screw 3 of screw rod is made dark wooden flute profile, directly be connected with sheet material B.
The aforesaid operations hole is generally circle, so pad and hole wall surface of contact also do in the arc-shapedly, and matches, and makes pad be the semicircle column type, does not get rid of and adopts other shapes, as shown in Figure 4.The mouth end of the opening on the pad and the shape of spiral shell neck are suitable.Provide several nut end face schematic representation as shown in Figure 3, also can mix special spanner.
