Abstract
The utility model belongs to a mechanical connecting piece and particularly relates to a fastening connecting piece between objects with contact surfaces. A wedge-shaped groove is arranged at the end part of a rod-shaped fastening piece of the fastening connecting piece. When in connecting state, a wedge is inserted into the corresponding wedge-shaped groove, and a connected piece is arranged in a corresponding wedge-shaped blind hole. The fastening connecting piece has the following characteristics: the structure is simple; the operation is easy, quick and convenient; the working efficiency can be greatly increased, the connection is firm as well as reliable, and the appearance of a connected object cannot be damaged.
Description
Technical field
The utility model belongs to a kind of mechanical fastener, particularly will have the fastening connection piece that interfixes between the object of surface of contact.
Background technique
In daily life, usually need object with two separation to be fastenedly connected and be integral, connecting the general mode that adopts for the mechanical fixation between the object at present has: screw connection, riveted joint, welding and bonding.
Screw connects and riveted joint need be connected the surface Machining through hole of thing, with screw or rivet two objects are connected again, this Placement can produce destruction to the surface that is connected thing, and influence is connected the attractive in appearance of thing, and therefore the occasion in some specific (special) requirements is not suitable for using; Screw connects in addition or the intensity of riveted joint is lower, and it is stressed that especially pulling rivet only relies on one deck thin aluminum top, is easy to lose efficacy; This Placement also exists pointwise to connect consuming time, consumption power, the problem that working efficiency is lower.
Though welding and the bonding damage that can avoid being connected the surface of thing, its working efficiency is lower, and operation is inconvenient; The connection of welding can only rely on the joint strength of two articles to guarantee join strength, and shorter when seam length, and two articles dislocation size is big and when being subjected to, connect seam fracture easily; And need rely on the multifactor join strengths that guarantee such as the surface treatment degree that is connected thing, viscose quality, working environment when bonding, as long as a certain factor is not suitable for, join strength will be had a greatly reduced quality.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of fastening connection piece, and it is simple in structure, and processing ease and convenient can be increased work efficiency greatly, and firm and reliable connection is not destroyed the appearance that is connected thing.
Solving the scheme that technical problem of the present utility model adopts is: being shaped as of fastening piece is shaft-like, and its end has wedge slot, when this fastening piece is in coupled condition, inserts chock in corresponding wedge slot, in the pairing wedge shape blind hole of the connected piece of packing into.
Fastening piece described in the utility model has two kinds of linkage structures, and wedge slot all is with at the two ends of (1) fastening piece, inserts behind the chock with the wedge shape blind of relative connected piece to connect; (2) end of fastening piece all is with wedge slot, is connected with the wedge shape blind of a connected piece behind the insertion chock; The other end of fastening piece is threaded, is connected with the screw of another connected piece.
The beneficial effects of the utility model are: this fastening piece is in the inboard of connected piece that two articles is fixedly connected, does not therefore destroy the appearance that is connected thing, can keep the smooth outward appearance of object; As long as to two articles just exert pressure can with fastening piece the wedge slot distending, tightly be stuck in the wedge shape blind hole of connected piece, so the operation when connecting is very convenient, has improved installment work efficient greatly; Big more to exerting pressure of connected piece, connect firmly more, the axially and radially while of fastening piece all provides the fastening force that is connected, so the join strength of object improves greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Each label is represented successively among the figure: connected piece 1, fastening piece 2, chock 3, wedge shape blind hole 4, connected piece 5, wedge slot 6.
Embodiment
Referring to Fig. 1, being shaped as of this fastening piece 2 is shaft-like, has wedge slot 6 in its end, and chock 7 correspondences are used with wedge slot 6.When being in coupled condition, in the wedge slot 6 of this fastening piece 2, insert chock 3, pack into then on the connected piece 5 in the corresponding wedge shape blind hole 4, connected piece 1 and connected piece 5 are compressed, the end of this fastening piece 1 is by distending, tightly be stuck in the wedge shape blind hole 4, thereby connected piece 1 and connected piece 5 are linked into an integrated entity securely.Linkage structure shown in Figure 1 can be adopted in the end of this fastening piece, and an end of fastening piece 2 all is with wedge slot 6, inserts chock 3 backs and is connected with wedge shape blind hole 4 expansions of a connected piece 5, and the other end of fastening piece 2 is threaded, is connected with the screw of another connected piece 1.Also can adopt the two ends of fastening piece all to be with wedge slot, insert behind the chock with the wedge shape blind of relative connected piece and connect.If be processed into the roughened surface of band pawl between the surface of contact with chock 3 and wedge slot 6, it is loosening to guarantee that so more fastening piece 2 is stuck in the wedge shape blind hole 4.
Claims (3)
1. fastening connection piece, it is characterized in that: the end of shaft-like fastening piece has wedge slot, inserts chock in the corresponding wedge slot of coupled condition, in the pairing wedge shape blind hole of the connected piece of packing into.
