Description

The pipe fitting compactor

The utility model relates to a kind of pipe fitting compactor that axially plastic tube is pressed on the close connection of envelope on the pipe fitting with clip.

Because novel free of contamination plastic water pipe is progressively substituting galvanizing pipe, and the plastic tube of this kind structure can not guarantee because of the connection reliability with pipe fitting.Present a kind of new plastic tube and the pipe fitting connection structure connecting that occurs, this new syndeton is when each section of load plastic tube, spout diameter with plastic tube enlarges earlier, insert pipe fitting again, with clip axial compression plastic tube is pressed on the pipe fitting and is tightly connected, so it is very reliable that pipe fitting is connected with plastic tube, can not leak.But in the constructing operation process, the distortion of the plastic tube mouth of pipe is tightly connected with pipe fitting, therefore can't implements the installation of this kind new construction owing to there is specific purpose tool directly clip to be moved axially.

The purpose of this utility model provides a kind of installation, easy to carry, and operation is light and handy, the pipe fitting compactor of long service life.

The utility model for reaching technique scheme is: a kind of pipe fitting compactor, it is characterized in that: the end top has the caliper of U type groove that horizontal jack is arranged, the end top is housed in the jack has U type groove and bottom that the movable press strip of tooth bar is arranged, the sidepiece of pressing nail and facing toward movable press strip is housed on the caliper, be installed in the tooth bar engagement of interior gear of caliper and movable press strip, the top of flexible handle is hinged on caliper, locating detent that can lock gear is hinged on flexible handle, and join with locking mechanism in the flexible handle, spring is equipped with in the middle and upper part of caliper and the middle and upper part of flexible handle.

The utility model adopts the advantage after the technique scheme to be: because pipe fitting compactor of the present utility model, constitute by caliper, movable press strip, flexible handle, gear and locating detent, and connect into an overall structure, and not only simple in structure, and easy to carry and store.In work progress, U type groove on the caliper and the U type groove on the movable press strip are contained on clip and the pipe fitting, locating detent withstands gear, press flexible handle, the locating detent handsetting gear rotates, gear is the tooth bar motion of drive activity press strip then, movable press strip moves to the direction of caliper, make the distance between the U type groove of the U type groove of caliper and movable press strip more and more littler, to pipe fitting, simple to operate the clip axial compression, a people can operate, so it is very convenient that site operation is installed, and operation is also very light and handy, can improve efficiency of construction.Compactor has adopted the motion of rack-and-pinion in addition, and compactor is difficult for breaking down, so the compactor long service life of this kind structure.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Fig. 1 is the structural representation of the utility model pipe fitting compactor.

Fig. 2 is the side diagrammatic sketch of Fig. 1.

Fig. 3 is the partial schematic sectional view at gear position.

Pipe fitting compactor of the present utility model shown in Fig. 1～3, the end top has the caliper 2 of U type groove 2-1 that a horizontal jack 2-2 is arranged, the end top is housed in the jack 2-2 has U type groove 1-1 and bottom that the movable press strip 1 of tooth bar is arranged, the sidepiece of pressing nail 6 and facing toward movable press strip 1 is housed on the caliper 2, this pressure nail 6 can adopt screw, directly is pressed on the sidepiece of movable press strip 1; Also can be as shown in Figure 2, in the pit of the bottom of pressure nail 6 steel ball 11 is housed, nail 6 is pressed on the sidepiece of movable press strip 1 by steel ball 11.Gear 5 is installed in the caliper 2 by pivot pin 15, and is meshed with the tooth bar of movable press strip 1, and the top of flexible handle 4 also is hinged at caliper 2 by pivot pin 15.Locating detent 3 that can lock gear 5 is hinged on flexible handle 4, and joining of locking mechanism and locating detent 3 arranged in the flexible handle 4, and during work, the front end of locating detent 3 withstands on the wide tooth of gear 5, and the rear end of locating detent 3 is then headed on by locking mechanism; When not working, rotate to an angle its side and locking mechanism of the front end out-of-gear 5 of locating detent 3, locating detent 3 joins.As shown in Figure 3, described locking mechanism is made up of little spring 13 and steel ball 12, and little spring 13 is contained among the blind hole 4-1 of flexible handle 4, and steel ball 12 is arranged on the top of little spring 13 and the rear end or the sidepiece of locating detent 3 joins.The middle and upper part of the middle and upper part of caliper 2 and flexible handle 4 all is fixedly connected with pin 14, the two ends of spring 10 are connected on the pin 14, after flexible handle 4 pressure are eliminated, flexible handle 4 sets back under the effect of spring 10 automatically, carry out work again, as shown in Figure 1, this spring 10 adopts the roll bending spring.

In order to adapt to and satisfy the installation of the pipe of different size series, shown in Fig. 1～2, C shape cover 9 all is housed in the U type groove 1-1 of U type groove 2-1 on the caliper 2 and movable press strip 1, the screw 7 that is contained in U type groove 2-1,1-1 lateral surface is connected with steel wire 8, and C shape cover 9 by being contained in the other steel wire of U type groove 2-1,1-1 8 location.

The utility model is when work, two U type groove 2-1 of compactor, 1-1 is contained on clip and the pipe fitting, pressing nail 6 to be pressed on the movable press strip 1, the front end of locating detent 3 is withstood on the flank profil of gear 5, depress flexible handle 4, flexible handle 4 is being with 5 rotations of locating detent 3 handsetting gears, gear 5 is being with tooth bar that movable press strip 1 is moved to caliper 2 directions simultaneously, and clip is drawn to pipe fitting, decontrols flexible handle 4, under spring 10 effects, flexible handle 4 resets, and depresses flexible handle 4 again, and gear 5 is rotated, movable press strip 1 moves to caliper 2 directions again, until clip pipe and pipe fitting is sealed close linking together.
