The connecting rod can fix the clamp body and the cover plate of the parallel groove clamp more firmly and effectively.
The first positioning rod is connected with the first positioning hole through a bolt, and the second positioning rod is connected with the second positioning hole through a bolt. The bolt connection enables the positioning hole and the positioning rod to be assembled stably and tightly.
One end of the connecting rod is connected with one end of the first positioning rod in a welding mode, the other end of the connecting rod is connected with one end of the second positioning rod in a welding mode, and the connecting rod after welding is parallel to the direction of the bolt hole. In the in-service use, the locating lever is in bolt-up back reassembling to parallel groove clamp, set up the connecting rod into with locating lever welded connection for in-service use, can confirm the length of connecting rod according to the actual distance between apron and the fastener body, after having confirmed the length of connecting rod, the relative position between two locating levers is fixed to the reuse connecting rod. The welding assembly of connecting rod and locating lever makes the locating lever to the location between apron and the fastener body more accurate.
For making the location of locating lever group to this fastener more balanced stable, set up to: the number of the first positioning holes is two, and the number of the second positioning holes is two.
For promoting the lightweight degree of apron, set up to: the thickness of the middle part of the cover plate is larger than that of the edge of the cover plate.
The positioning rod group further comprises a C-shaped connecting piece, one end of the C-shaped connecting piece is connected with the first positioning rod, and the other end of the C-shaped connecting piece is connected with the second positioning rod.
Compared with the prior art, the utility model has the beneficial effects that:
the utility model has reasonable structure and safe and convenient use. The utility model provides a looseness-proof bolt type parallel groove clamp which is compared with the existing parallel groove clamp with a clamp body and a cover plate. The first positioning rod and the second positioning rod are fixedly connected through a connecting rod. When the parallel groove clamp clamps a power transmission line, after the cover plate and the clamp body are fastened through bolts, the positioning rods of the positioning rod group are assembled to the cover plate and the clamp body respectively to position and fasten the cover plate and the clamp body. Because fixedly connected with connecting rod between first locating lever and the second locating lever, consequently the relative position between second locating lever and the first locating lever also keeps fixed, and then the connecting rod has also played spacing effect to apron and fastener body. The assembly setting of locating lever group can be even avoid after the bolt of fastener is not hard up, the bolt takes place not hard up, fixed not stable enough to between apron and the fastener body, and then causes the contact resistance between centre gripping chamber and the transmission line to change big bad phenomenon and take place.
