Problems solved by technology

[0003] It can be seen that the traditional bolt-connected clamp has many parts, which is not easy to process and has the disadvantages of high production cost; in addition, due to the thick material of the tongue plate, there is a height difference between it and the steel belt. As a result, there is a dead spot in the traditional clamp, which affects the sealing effect of the clamp

Embodiment Construction

[0019] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0020] A long-tongue clamp, including a steel strip coil 8, a bolt 1 and a nut 3, the innovation of which is that both ends of the steel strip coil are bent vertically upward to form a baffle part 5, and the two baffle parts Mounting holes are provided on each of them, and the nuts are opposite to the mounting holes and welded on the outside of one of the baffles. The bolts are fitted on the mounting holes and cooperate with the nuts to adjust the diameter of the steel coil. A long tongue 4 is stamped on the steel strip roll below the baffle at one end, and a long hole 7 is formed on the steel strip below the other end baffle. The long tongue is bent 180° and embedded in the long inside the hole.

[0021] A shield 2 is also bent outwards ab...

Abstract

The invention relates to a long-tongued clamp, which includes a steel strip coil, bolts and nuts. There is a mounting hole, the nut is opposite to the mounting hole and welded on the outer side of one of the baffle parts, the bolt is passed through the mounting hole and cooperates with the nut to realize the adjustment of the diameter of the steel coil. A long tongue is stamped on the steel strip roll below the baffle at one end, and a long hole is formed on the steel strip below the baffle at the other end, and the long tongue is bent 180° and embedded in the long hole. The invention has scientific and reasonable structural design, simple structure, low production cost, easy processing, good sealing effect and long service life, and is a highly innovative long-tongue clamp.

Description

technical field [0001] The invention relates to a pipe connection piece, in particular to a long tongue clamp. Background technique [0002] The existing bolt-connected clamp structure is relatively complicated, generally composed of steel strips, tongue plates, connecting shafts, bolts and sheaths. The steel strip is a steel strip coil, and both ends of the steel strip coil are curled outward to form a mounting After being rolled, it is welded on the steel strip, and the connecting shafts are installed in the two installation rolls, and the bolt fastening through holes are formed on the connecting shafts, and the bolt fastening through holes are formed on the rolling body of the mounting rolls. Corresponding to the piercing holes, the bolts are mounted on the two connecting shafts, and the bolts realize the reduction and expansion of the steel strip coil by shortening or increasing the distance between the two connecting shafts, that is, to realize the bolt-connected clamp ...
