Abstract
The utility model relates to a connector reinforcing device, and provides a sealing and locking device for an air bag pipe connector. The sealing and locking device comprises a first inverted-T-shaped sealing hoop and a second inverted-T-shaped sealing hoop. Half-round grooves are formed in the two sealing hoops. The second sealing hoop is arranged above the first sealing hoop, the first sealing hoop and the second sealing hoop are symmetrically arranged in the vertical direction, one sides of the two sealing hoops are connected through a rotating pin so that the other sides of the two sealing hoops can rotate and expand. Round through holes are formed in the other sides of the two sealing hoops. The two through holes are fixed and locked through a nut and a screw. The sealing and locking device is simple in structure, good in sealing performance, easy to install, resistant to the sun and the rain, and long and stable in effect.
Description
Technical field
The utility model belongs to joint reinforcing device., relates in particular to a kind of sealing-locking device for bellows chamber pipe joint.
Background technique
At present, it is of a great variety that the device to plastic tube joint sealing on market exists, and common joint sealing device has circumferential band, buckle, band and iron wire.But circumferential band itself is made up of thin steel band, use screw locking, not strong on ambient adaptability, often can, because environmental factor initiating device itself is out of shape or gets rusty, cause sealing variation.Buckle is generally made up of two semicircles, and in the time of locking, junction easily produces locking blind area, and sealing effect is not good even cannot be sealed.Cassette tape and iron wire are more traditional methods, but affected by environment larger, can occur getting rusty along with the time, the phenomenon such as fracture, and final sealing effect also can disappear.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of bellows chamber pipe seal locking device, prevents the phenomenon leaking air after joint splicing.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of bellows chamber pipe seal locking device, comprise the first sealing hoop and second sealing hoop of two convexs, two described sealing hoop inside are equipped with semicircular groove, described the second sealing hoop is positioned at the top of described the first sealing hoop, and described the first sealing hoop and upper and lower being symmetrical arranged of described the second sealing hoop, a side of two described sealing hoops connects rotatable opening between the opposite side that makes two described sealing hoops by rotation pin; Be equipped with circular through hole at the opposite side of two described sealing hoops, between two described holes are logical, mistake nut and screw are fixing locked.
The beneficial effects of the utility model are: a side of two described sealing hoops is connected and fixed by rotation pin, makes operator when mounted, has reduced workload; Described apparatus structure is simple, and good airproof performance is stood and exposed to the sun and rain, can steady in a long-term having an effect.
On the basis of technique scheme, the utility model can also do following improvement.
Further, the two ends of each described groove are respectively provided with the sealed tongue of an arc.
Adopt the beneficial effect of above-mentioned further scheme to be: by the sealed tongue increasing in groove, after two described sealing hoops are locked, the expansion function that sealed tongue itself has, strengthens the ability of the isolated air of this device.
Further, the angle that between the opposite side of two described sealing hoops, rotation is opened is 0～225 ℃.
Adopt the beneficial effect of above-mentioned further scheme to be: by rotation pin connect two described sealing hoops, the angle that sealing hoop opens, easy-to-operat personnel install.
Accompanying drawing explanation
Fig. 1 is sealing device structure figure of the present utility model.
In accompanying drawing, the list of parts of each label representative is as follows:
1, the first sealing hoop, 2, the second sealing hoop, 3, rotation pin, 4, plastic tube, 5, pipe coupling, 6, screw, 7, nut, 8, sealed tongue, 9, through hole, 10, groove.
Embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of bellows chamber pipe seal locking device, comprise the first sealing hoop 1 and second sealing hoop 2 of two convexs, two described sealing hoop inside are equipped with semicircular groove 10, described the second sealing hoop 2 is positioned at the top of described the first sealing hoop 1, and described the first sealing hoop 1 is with described second sealing hoop 2 is upper and lower is symmetrical arranged, and a side of two described sealing hoops connects rotatable opening between the opposite side that makes two described sealing hoops by rotation pin 3; Be equipped with at the opposite side of two described sealing hoops that between 9, two described holes of circular through hole logical 9, to cross nut 7 fixing locked with screw 6, preferred nut 7 shapes are wing nuts, and preferred screw 6 is fastening screw trip bolts.
The two ends of each described groove 10 are respectively provided with the sealed tongue 8 of an arc.Two described sealing hoops are all that stainless steel is made.The angle that between the opposite side of two described sealing hoops, rotation is opened is 0～225 ℃, and easy-to-operat personnel install.
In this example, operator connect after pipeline in pipe coupling 5, dock by plastic tube 4, then break the first sealing hoop 1 and the second sealing hoop 2 into two with one's hands, make it to clamp plastic tube 5, the sealed tongue that is provided with by each groove 10 two ends 8 and tighten wing nut 7 and reach the effect of completely isolated air.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
