Abstract
The utility model discloses a novel fastener which comprises a dovetail slot pipe fastening tee joint, a fastening cable-stayed piece, bolts and nuts. The dovetail slot pipe fastening tee joint is formed by two identically-arranged individual bodies in a combination mode, and comprises a longitudinal dovetail slot, a transverse slot and screw holes. The fastening cable-stayed piece comprises a left fastening cable-stayed piece and a right fastening cable-stayed piece, and a clamp notch and a screw hole are formed in the left fastening cable-stayed piece and the right fastening cable-stayed piece respectively. The two identically-arranged individual bodies of the dovetail slot pipe fastening tee joint are combined and connected through the bolts and the nuts in matched use. The novel fastener of dovetail slots accurately locates dovetail slot pipes by adopting the tee joint type fastening mode and the cable-stayed fastening mode, the novel fastener has the advantages of being firm in connection, easy to operate, strong in reutilization, simple in structure, and convenient to implement.
Description
Technical field
The utility model relates to a kind of fastening piece of steel pipe, particularly a kind of novel fastener.
Background technique
Dovetail groove is used in a large number on the connection of mechanical devices and lathe, use the steel pipe of dovetail groove not only be convenient to engage and also bearing capacity larger than common steel tube, but the connection between existing dovetail barrel is all generally to adopt dovetails that two dovetail grooves are connected, and the dovetail barrel can only be carried out to " one " font connects, for " ten " font of dovetail barrel generally adopt contiguous block and in addition screw bolt and nut fix, fastening poor effect, the dovetail barrel easily slides, and the location inaccuracy, switching performance is poor.
The model utility content
In order to overcome the deficiency in background technique, of the present utility modelly provide a kind of novel fastener with high tautness and high stability.
Novel fastener of the present utility model, comprise the fastening threeway of dovetail barrel, fastening oblique pull part, screw bolt and nut, the individuality that the fastening threeway of described dovetail barrel is two identical settings combines, comprise vertical dovetail groove, horizontal dovetail groove and screw, described fastening oblique pull part comprises left fastening oblique pull part and right fastening oblique pull part, be provided with bayonet socket and screw on left fastening oblique pull part and right fastening oblique pull part, the fastening threeway of described dovetail barrel is connected the individuality of two identical settings by being used in conjunction with of screw bolt and nut.
As preferably, on the fastening threeway of described dovetail barrel and fastening oblique pull part, be provided with screw.
As preferably, described screw is circular.
The utility model compared with prior art, it has following beneficial effect: dovetail groove fastening piece of the present utility model, the employing Three way type is fastening accurately locates the dovetail barrel with the fastening two class fastening means of oblique pull, have that be connected firmly, simple to operate, reusing is strong etc. a little, and simple in structure, implement convenient.
The accompanying drawing explanation
Fig. 1 is the utility model embodiment's structural representation,
Fig. 2 is the structural representation of the fastening threeway of dovetail barrel,
Fig. 3 is the structural representation of fastening oblique pull part.
Embodiment
As Fig. 1, a kind of novel firmware shown in Fig. 2 and Fig. 3, comprise the fastening threeway 2 of dovetail barrel, fastening oblique pull part 3, bolt 4 and nut 5, the individuality that the fastening threeway 2 of described dovetail barrel is two identical settings combines, comprise vertical dovetail groove 6, horizontal dovetail groove 7 and screw 8, for dovetail barrel 1 being carried out to " ten " font, connect, described fastening oblique pull part 3 comprises left fastening oblique pull part and right fastening oblique pull part, be provided with bayonet socket 9 and screw 8 on left fastening oblique pull part and right fastening oblique pull part, the fastening threeway 2 of described dovetail barrel is connected the individuality of two identical settings by being used in conjunction with of bolt 4 and nut 5.
