Abstract
The utility model relates to a kind of interior envelope vent plug, and the outer rim of disk connects rubber ring, between rubber ring and the edge of disk, aerated rubber loop is set, and the two sides of disk arranges respectively cylinder and threaded column, and the end of threaded column arranges tapped small sleeve; The end of cylinder arranges end thread post, end thread post is by external screw thread branch sleeve, the end of cylinder arranges equally distributed fan plate along cylindrical outer wall, fan plate arranges screwed hole at place, right angle, fan plate is fixedly connected with gripper shoe by screwed hole, and fan plate is positioned at the chute of gripper shoe, on fan plate, arc-shaped slot is set, arc-shaped slot is connected with gripper shoe by bolt, in the mounting groove of the gripper shoe other end, is bolted castor.The utility model 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; the utility model is subjected to displacement in protecting pipe outside, and during operation, different shutdown, has improved production efficiency and yield rate.
Description
Technical field
The utility model 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 utility model 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 utility model is taked for the technical problem existing in solution known technology is:
A kind of interior envelope vent plug, comprise disk, the outer rim 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, on described fan plate, be also provided with arc-shaped slot, 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 the good effect that the utlity model has are: the utility model 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 utility model 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 the utility model structural front view;
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 utility model, 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 13, 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.
The utility model is positioned in oversheath pipe while using; 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 utility model is subjected to displacement in protecting pipe outside, and during operation, different shutdown, has improved production efficiency and yield rate.
Above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit, and those of ordinary skill in the field should be appreciated that still and can modify or part technical characterictic is equal to replacement the specific embodiment of utility model; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the technology that the utility model is asked for protection.
