Abstract
The invention relates to an inner seal air plug. The inner seal air plug comprises a disc, wherein the external circle of the disc is connected with a rubber ring; an air inflating rubber ring is arranged between the edges of the rubber ring and the disc; two surfaces of the disc are respectively provided with a cylinder and a threaded column, and the end part of the threaded column is provided with a small sleeve with an internal thread; the end part of the cylinder is provided with an end part threaded column connected with the sleeve through an outer thread; the end part of the cylinder is provided with fan-shaped plates which are distributed uniformly along the outer wall of the cylinder; the fan-shaped plates are provided with threaded holes in the right-angle parts, are fixedly connected with a support plate through threaded holes, are positioned in a chute of the support plate, and are also provided with arc groove holes connected with the support plate through bolts; an installation groove in the other end of the support plate is internally connected with a trundle through a bolt. The inner seal air plug provided by the invention is simple in structure; the outer edge of the rubber ring and the inner wall of an outer protective sleeve are in tight contact, and a seal effect is achieved; meanwhile, under the driving by a traction machine, the trundle moves along the inner wall of the outer protective sleeve, so that the inner seal air plug provided by the invention moves in the outer protective sleeve, and machine halt is avoided in operation, and the production efficiency and the rate of finished products are improved.
Description
Technical field
The invention belongs to oversheath pipe production technical field, particularly a kind of interior envelope vent plug of producing for oversheath pipe.
Background technology
In plastic extruding forming equipment, plastic extruder is referred to as main frame conventionally, and the follow-up equipment plastic extruding forming machine supporting with it is called subsidiary engine.
At plastic extruder, produce in the process of oversheath pipe, can be according to the oversheath pipe of need of production intercepting different length, to meet customer need.Therefore, on the inwall of protecting pipe, gas-tight sealing is set outside, and on current production line, the sealing device using is that eva foam plate is set between two disks, this sealing device can bring two defects: the one, and the sealing of eva foam plate is poor, easily produces gas leakage; The 2nd, sealing device maintains static in protecting pipe outside, can bring destructive production, is unfavorable for recycling for a long time.
Summary of the invention
The present invention can move for the technical problem existing in solution known technology provides a kind of, the interior envelope vent plug of good seal.
The technical scheme that the present invention takes for the technical problem existing in solution known technology is:
A kind of interior envelope vent plug, comprise disk, the cylindrical of described disk is connected with rubber ring, between described rubber ring and the edge of disk, is provided with aerated rubber loop, the two sides of described disk is respectively arranged with cylinder and threaded column, and the end of described threaded column is provided with tapped small sleeve; The end of described cylinder is provided with end thread post, described end thread post is by external screw thread branch sleeve, the end of described cylinder is provided with equally distributed fan plate along cylindrical outer wall, described fan plate is provided with screwed hole at place, right angle, described fan plate is fixedly connected with gripper shoe by screwed hole, described fan plate is positioned at the chute of gripper shoe, the upper arc-shaped slot that is also provided with of described fan plate, described arc-shaped slot is connected with gripper shoe by bolt, in the mounting groove of the described gripper shoe other end, is bolted castor.
Described rubber ring is connected on disk by pressure ring.
Between described cylinder one end and disk, be provided with floor.
The quantity of described fan plate is 6.
Advantage and good effect that the present invention has are: the present invention is simple in structure; rubber ring outer rim and oversheath inside pipe wall close contact; play the effect of sealing; simultaneously under the drive of hauling machine; castor moves along oversheath inside pipe wall; thereby the present invention is subjected to displacement in protecting pipe outside, and during operation, different shutdown, has improved production efficiency and yield rate.
Accompanying drawing explanation
Fig. 1 is structural front view of the present invention;
Fig. 2 is Fig. 1 top view;
Fig. 3 is Fig. 1 upward view;
Fig. 4 is supporting plate structure schematic diagram.
In Fig. 1～Fig. 4,1. rubber ring, 2. aerated rubber loop, 3. disk, 4. floor, 5. gripper shoe, 501. mounting grooves, 502. chutes, 6. threaded column, 7. small sleeve, 8. fan plate, 9. end thread post, 10. sleeve, 11. castors, 12. cylinders, 13. pressure rings.
The specific embodiment:
For further understanding summary of the invention of the present invention, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1～Fig. 4, a kind of interior envelope vent plug, comprise disk 3 and rubber ring 1, rubber ring 1 is connected to or is connected on disk 3 to disk 3 by pressure ring 1, between the edge of rubber ring 1 and disk 3, be provided with aerated rubber loop 2, the two sides of disk 3 is respectively arranged with cylinder 12 and threaded column 6, and the end of threaded column 6 is provided with tapped small sleeve 7; Between cylinder 12 one end and disk 3, be provided with floor 4, floor 4 plays the effect of reinforcement, the other end of cylinder 12 is provided with equally distributed fan plate 8 along cylinder 12 outer walls, the quantity of fan plate 8 is 6, fan plate 8 is provided with screwed hole at place, right angle, fan plate 8 is fixedly connected with gripper shoe 5 by screwed hole, fan plate 8 is positioned at the chute 502 of gripper shoe 5, the upper arc-shaped slot that is also provided with of fan plate 8, arc-shaped slot is connected with gripper shoe 5 by bolt, and the angle between gripper shoe 5 and cylinder 12 is changed.In the mounting groove 501 of gripper shoe 5 other ends, be bolted castor 11.The end of cylinder 12 is provided with end thread post 9, and end thread post 9 is by external screw thread branch sleeve 10.
When using, the present invention is positioned in oversheath pipe; the end of small sleeve 7 is connected on main frame; the end of sleeve 10 is connected on haulage gear; now rubber ring 1 outer rim and oversheath inside pipe wall close contact, play the effect of sealing, simultaneously under the drive of hauling machine; castor 11 moves along oversheath inside pipe wall; thereby the present invention is subjected to displacement in protecting pipe outside, and during operation, different shutdown, has improved production efficiency and yield rate.
