Description

U Type bolt pipe clamp

Technical field

The present invention relates to a kind of U-bolt pipe clamp, belong to technical field of fastening,.

Background technology

At present, the Chinese patent of Publication No. CN1252860A discloses a kind of pipe clamp, this pipe clamp has the clamp of two expansible Guan Bis, opening part at pipe clamp is provided with outwardly directed grip flange, being set with one in two clamps only at the rubber parts of pipe clamp opening part opening, this rubber parts has side and clasps the C-shaped lateral margin of clamp；The grip flange of this pipe clamp is provided with screw element, the both sides of screw element one end and middle part are respectively equipped with the prodger being bent upwards and the tongue piece tilted downwards, one of them clamp is provided with the hole installing fishbolt, and this clamp is provided with, with the transition region of its grip flange, the through hole coordinated with tongue piece, tongue piece makes prodger be close on the C shape lateral margin of rubber parts through through hole, and another clamp is provided with and coordinates with fishbolt and outwardly open gap.

During use, open pipe clamp, pipe fitting is placed between two clamps, then fishbolt is passed in the hole being arranged in clamp the screwed hole being threaded into part, force in tongue piece rotatable screw, prodger is made to press to the C-shaped lateral margin of rubber parts, when the head of fishbolt crosses outer end, gap, release tab, prodger is radially outward pressed by the C shape lateral margin of rubber parts along clamp, makes screw element reversely rotate and drives fishbolt to enter in gap, completing pipe fitting and pre-fix, again fishbolt is tightened, complete the fixing work to pipe fitting.

Although this pipe clamp disclosure satisfy that the demand of clamping pipe fitting to a certain extent, but there is also some deficiency following:

1, screw element drives the power of fishbolt reversion to be produced by rubber parts, on the one hand, tongue piece makes the deflection of rubber parts limited, the elastic force causing rubber parts to act on tongue piece will disappear in the shortest stroke, and fishbolt reversely rotated and to bring in gap, need tongue piece to have enough strokes, this results in fishbolt and tends not to automatic in-position, also need to manual setting, it has not been convenient to；On the other hand, the local deformation of rubber parts or the aging elastic failure that all easily causes, elastic force reduce also result in fishbolt cannot be automatically into gap, and the cost changing whole rubber parts is the highest；

2, one end of two clamps is hinged fixing, owing to clamp thickness is less, easily causes clamp deformation, and then causes fixing during pipe fitting the most firm；

3, in pipe fitting installation process, while needing to make prodger press to rubber parts to screw element force in advance, fishbolt to be directed at and opened gap on one side, cause installation process complexity inconvenient, and be positioned on tongue piece to the position of screw element force, interfere between tongue piece and pipe fitting and cause exerting a force constant, the finger of operator may be weighed wounded.

Summary of the invention

The technical problem to be solved is the defect overcoming prior art, it is provided that a kind of U-bolt pipe clamp, and it can not only meet the clamping requirement of the pipe fitting of various caliber, and better reliability, lifting is convenient.

The present invention solves above-mentioned technical problem and adopts the technical scheme that: a kind of U-bolt pipe clamp, and it includes:

Base, the top of described base connects has boatswain chair, the lower end of described base to be provided with pipe clamp clamping part；

U-bolt, the two ends of described U-bolt are flexibly connected with pipe clamp clamping part mutually by fastening assembly respectively；

Tube lining plate, the retained part of described tube lining plate forms, with the retained part of pipe clamp clamping part, the clamping face that the outer wall with pipe fitting matches, and the two ends of tube lining plate are connected on U-bolt；By screwing fastening assembly, pipe fitting is clamped on clamping face.

Further providing for the concrete structure of a kind of base to ensure that lifting is stable, described base includes two pieces of tube sheets and two pieces of backing plates, and the side of two tube sheets is connected by one piece of backing plate, and the opposite side of two tube sheets is connected by another block backing plate.

After have employed technique scheme, present invention employs U-bolt, and go to be connected by fastening assembly with pipe clamp clamping part with its two ends, this version goes for the pipe fitting of various different tube diameters, and its tube lining plate uniform force in rundown process, do not have that tube lining plate pressure is uneven and the phenomenon of pipe fitting damaged that causes, and better reliability, install more convenient to operate；It addition, be provided with boatswain chair on the base of the present invention, convenient lifting.

Detailed description of the invention

Being clearly understood to make present disclosure be easier to, below according to specific embodiment and combine accompanying drawing, the present invention is further detailed explanation.

As shown in Figure 1, 2, a kind of U-bolt pipe clamp, it includes:

Base, the top of described base connects has boatswain chair 6, the lower end of described base to be provided with pipe clamp clamping part；

U-bolt 2, the two ends of U-bolt 2 are flexibly connected with pipe clamp clamping part mutually by fastening assembly respectively；

Tube lining plate 1, the retained part of tube lining plate 1 forms, with the retained part of pipe clamp clamping part, the clamping face that the outer wall with pipe fitting 3 matches, and the two ends of tube lining plate 1 are connected on U-bolt 2；By screwing fastening assembly, pipe fitting 3 is clamped on clamping face.

As it is shown in figure 1, base includes two pieces of tube sheets 3 and two pieces of backing plates 4, the side of two tube sheets 3 is connected by one piece of backing plate 4, and the opposite side of two tube sheets 3 is connected by another block backing plate 4.

The operation principle of the present invention is as follows:

Present invention employs U-bolt 2, and go to be connected by fastening assembly with pipe clamp clamping part with its two ends, this version goes for the pipe fitting of various different tube diameters, and its tube lining plate 1 uniform force in rundown process, do not have that tube lining plate 1 pressure is uneven and the phenomenon of pipe fitting damaged that causes, and better reliability, install more convenient to operate；It addition, be provided with boatswain chair on the base of the present invention, convenient lifting.
