Abstract
The utility model provides a miniature and portable tube withdrawal device, which comprises a ferrule I, a ferrule II and at least three top rods, wherein the ferrule I is formed by detachably connecting two arc-shaped rings via screw bolts, grooves are distributed evenly along the circumferential direction of the ferrule I, the number and size of each groove correspond to those of the top rods, the ferrule II is formed by detachably connecting two arc-shaped rings via screw bolts, thread holes are distributed evenly along the circumferential direction of the ferrule II, the number of the thread holes corresponds to that of the top rods, a square head is disposed at one end of each top rod, outer threads matching with each thread hole are disposed on the outer lateral walls of the top rods, each top rod is screwed on each thread hole, the other end of each top rod respectively abuts to each groove arranged on the ferrule I, and the ferrule I and the ferrule II can move oppositely alongthe axial direction by the aid of rotation of each top rod. The tube withdrawal device can be used for separating tubes in nonpermanent connection.
Description
Technical field
The utility model relates to a kind of tubing and moves back pipe unit, and it is used for the tubing that two impermanencies connect is separated from joint.
Background technology
Known pvc pipe has been widely used in occasions such as running water pipe or sewer, and particularly along with the updating of PVC production equipment, bigbore pvc pipe is applied to the water mains conveyance conduit more and more.Problem of the thing followed is exactly that pvc pipe is when laying connection, because axiality can not accurately be controlled or sealing ring is askew by top, the tubing edge of inboard, drainage appears after causing two pvc pipes to connect, the pvc pipe coupling parts separation that just need connect two this moment connect operation after sealing ring is reapposed over correct position again.Because space, pvc pipe fabricating yard is limited, many times large-scale tubing moves back pipe unit and does not find a place where one uses one's talents, move back pipe operation with regard to the pipe unit that moves back that needs a small portable this moment, certainly for some tubing that connects by interference fit or sealing ring, can run into foregoing problems equally, so the pipe unit that moves back of a small portable of development and Design just seems particularly necessary.
The utility model content
The tubing that the purpose of this utility model provides a kind of small portable moves back pipe unit.
The technical scheme that the utility model adopted is such: a kind of tubing moves back pipe unit, comprise hoop cover one, hoop cover two and at least three push rods, described hoop cover one passes through the separable connection setting of bolt by two loop, hoop cover one along the circumferential direction is evenly equipped with the groove of corresponding push rod quantity and size, described hoop cover two passes through the separable connection setting of bolt by two loop, hoop cover two along the circumferential direction is evenly equipped with the screwed hole of corresponding push rod quantity, described each push rod one end is provided with square toes, the push rod lateral wall is provided with the external screw thread suitable with each screwed hole, each push rod revolves respectively to be located on each screwed hole and its other end pushes up respectively on each groove of being located at hoop cover one, and nationality in axial direction relatively moves hoop cover one and hoop cover two by the rotation of each push rod.
Aforementioned tubes is moved back pipe unit, and described push rod has four.
Aforementioned tubes is moved back pipe unit, and the madial wall of described hoop cover one and hoop cover two is provided with the bulge loop that circumferentially extends on a plurality of edges and is used to increase frictional force.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: by hoop cover one and hoop cover two respectively banding be sheathed on interconnective two tubing, evenly rotate then and revolve each push rod that is located on the hoop cover two, each push rod just will bind round cover one and transfer to from the joint of another tubing together with the tubing on it like this, this kind moves back the pipe unit compact conformation, be applicable to the small space operation, use very convenient.
Description of drawings
Fig. 1 is the stereogram of embodiment;
Fig. 2 is the three-dimensional exploded view of embodiment;
The specific embodiment
With reference to figure 1 and Fig. 2, embodiment discloses a kind of tubing and moves back pipe unit, comprise hoop cover 1,2 and four push rods 3 of hoop cover, described hoop cover 1 is connected setting by loop 11 and loop 12 by two bolts 13 are separable, whole hoop cover 1 roughly is the circle structure, hoop cover 1 along the circumferential direction is evenly equipped with four grooves 14, the aperture of described each groove 14 is than push rod 3 slightly larger in diameter, described hoop cover 2 is connected setting by loop 21 and loop 22 by bolt 23 is separable, hoop cover 2 along the circumferential direction is evenly equipped with four screwed holes 24, described each push rod 3 periphery wall are provided with the external screw thread suitable with each screwed hole 24, one end of each push rod 3 is provided with square toes 31 and twists with convenient wrench, each push rod 3 revolves respectively to be located on each screwed hole 24 and its other end pushes up respectively on each groove 14 of being located at hoop cover 1, is respectively equipped with six roads on the madial wall of described hoop cover 1 and hoop cover 2 and is used to increase frictional force along the bulge loop that circumferentially extends.When two PVC water pipes sealing ring in connection procedure is crooked when causing leaking, hoop cover 1 can be sheathed on an axial side of two pvc pipe connecting portions, to bind round cover 2 and be sheathed on the connecting portion opposite side, then push rod 3 is revolved respectively and be located on each screwed hole 24, evenly rotate each push rod 3 and make hoop cover 1 and hoop cover 2 be separated vertically, and then make two pvc pipes be separated along connecting portion.
Claims (3)
1, a kind of tubing moves back pipe unit, it is characterized in that: comprise hoop cover one, hoop cover two and at least three push rods, described hoop cover one passes through the separable connection setting of bolt by two loop, hoop cover one along the circumferential direction is evenly equipped with the groove of corresponding push rod quantity and size, described hoop cover two passes through the separable connection setting of bolt by two loop, hoop cover two along the circumferential direction is evenly equipped with the screwed hole of corresponding push rod quantity, described each push rod one end is provided with square toes, the push rod lateral wall is provided with the external screw thread suitable with each screwed hole, each push rod revolves respectively to be located on each screwed hole and its other end pushes up respectively on each groove of being located at hoop cover one, and nationality in axial direction relatively moves hoop cover one and hoop cover two by the rotation of each push rod.
