Term involved in this case is explained as follows:
12 medial surface of tightening platform refers to the face A in Fig. 1, that is, two tightening platforms are apart from nearest surface, with
The enclosure space that clamping part is surrounded is connected.
12 lateral surface of tightening platform refers to the face B in Fig. 1, that is, two tightening platforms are apart from farthest surface, straight
It connects towards extraneous.
Utility model content
In view of the above-mentioned problems, the utility model, which is intended to provide one kind, is solved perfectly in fastener cycle the inconsistent phenomenon that rotates
Line card.
The technical solution that the utility model solves the problems, such as is: a kind of line card, including card body, and the card body includes ring gripping
Portion, clamping part are equipped with open ports, are respectively connected with tightening platform in two end points of open ports, are close to tightening platform
Lateral surface is stacked with spatula, and spatula is equipped with first through hole, offers concave indentation in first through hole inner wall, flat in fastening
Second through-hole coaxial with first through hole is provided on platform at face first through hole；
It further include the riveting part that spatula and tightening platform is fixed, the riveting part includes flange, is perpendicularly fixed at flange
Hollow；The hollow is inserted into first through hole and the second through-hole simultaneously, and in hollow outer wall materials insertion concave indentation；
Hollow is fixedly connected with the second through-hole edge；The flange presses the spatula surface not being bonded with tightening platform.
In above scheme, the design of concave indentation, so that in the embeddable concave indentation of hollow outer wall materials, to be formed
Position limiting structure limits the relative rotation of spatula and tightening platform.Moreover, needing to be passivated after eliminating welding without welding
Equal post-processing steps.
Preferably, the length direction of the concave indentation is parallel with first through hole axis, and concave indentation is square along its length
To through first through hole inner wall.
In order to keep overall structure more attractive, the end face of the flange covering concave indentation, the finished appearance after covering is seen not
To concave indentation.
Preferably, the concave indentation is the groove of semicircular arc.
It is furthermore preferred that concave indentation semicircle arc radius is 0.5mm.
Further, the flange and hollow are integrally formed.
Further, the hollow and the second through-hole edge are integrally formed.
Preferably, the riveting part is squeezed to occur to be plastically deformed to extend by mold and is made by the second through-hole Border material.
Further, slot band is enclosed on the clamping part.Slot band is made of flexible material, such as rubber, with protection
Pipeline is pinched.
Preferably, the clamping part and tightening platform are integrally formed.A heel piece material bending and molding can be used.
The remarkable result of the utility model is:
1. the design of concave indentation, so that in the embeddable concave indentation of hollow outer wall materials, so that position limiting structure is formed,
The phenomenon that limiting the relative rotation of spatula and tightening platform, avoiding the rotation dislocation in line card fastener cycle.
2. needing the post-processing steps such as passivation after eliminating welding without welding, good appearance is easy to operate, processing effect
Rate is high.
