Description

A kind of plastic barrel flype

Technical field

The utility model relates to technical field of plastic processing equipment, specially a kind of plastic barrel flype.

Background technique

In life plastic barrel be often used to store and carry liquid, but during carrying plastic barrel by Plastic barrel can deformation occurs moment when downthrust, at this time the liquid moment inside plastic barrel be squeezed by lid and staving it Between spray, be not only not easy to carry, the liquid inside plastic barrel is there are more dangerous when corrosivity, so being badly in need of wanting a kind of The lid that can be folded Automatic-expanding can relieve stress, when needed so that the liquid splash inside plastic barrel be avoided to go out Come.

Utility model content

The purpose of this utility model is to provide a kind of plastic barrel flypes, to solve mentioned above in the background art ask Topic.

To achieve the above object, the utility model provides the following technical solutions: a kind of plastic barrel flype, including lid, The inside of the lid offers the fillet of screw, and the upper end of the lid is connected with top blind flange, the lower end surface of the top blind flange It is fixedly connected with folded tube, the upper surface edge of the lid has fixed card slot, the both ends of the folded tube and middle part folding It is folded that plastic flexible pipe is installed, spring ring is fixedly installed between the plastic flexible pipe, the low end face edge of the top blind flange is solid Surely it is connected with snap ring, the inner upper end of the lid is fixedly installed with barrier ring.

Preferably, it is fixedly connected positioned at the plastic flexible pipe of least significant end with the closed phase of the inner tip of lid, is located at top Plastic flexible pipe be mutually fixedly connected with the low side face of top blind flange, and connecting portion is located at the inside of snap ring.

Preferably, top blind flange is connected to inside realization and the lid of fixed card slot by snap ring when the folded tube is shunk It combines.

Preferably, the low side of the barrier ring is fixedly connected with rubber seal, and barrier ring stops when folded tube contraction Folded tube enters to the inside of lid.

Preferably, the surrounding of the lid offers antiskid thread.

Preferably, the snap ring is rubber system, and the inside two sides of fixed card slot are inlaid with rubber pad, snap ring and fixing card Slot is adapted.

Compared with prior art, the beneficial effects of the utility model are as follows:

The utility model is mutually threadedly coupled using the fillet of screw with plastic barrel by twisting lid, in modeling bucket in transport liquid When staving is squeezed in the process, internal liquid will receive pressure to movement at the opening on staving top and bung, largely Liquid moment be moved to the pressure that formation is very big at bung, liquid can be rushed open snap ring point by the inside of fixed card slot at this time From, top blind flange can generate displacement straight up at this time, and under the dragging of fluid pressure and top blind flange folded tube by Folded state is opened, and liquid can enter to the inside of folded tube, is caused inside by external force extruding to effectively slow down staving The generation of liquid splash phenomenon can slow down the pressure moment that liquid generates when folded tube is opened by folded state, effective anti- The appearance for causing expulsion events in transportational process due to being squeezed liquid is stopped.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-4 is please referred to, a kind of embodiment provided by the utility model: a kind of plastic barrel flype, including lid 2, lid The inside of body 2 offers the fillet of screw 3, and the upper end of lid 2 is connected with top blind flange 1, and the lower end surface of top blind flange 1 is fixedly connected with Folded tube 4, the upper surface edge of lid 2 have fixed card slot 5, and it is soft that the both ends of folded tube 4 and middle part folding are equipped with plastics Pipe 9 is fixedly installed with spring ring 8 between plastic flexible pipe 9, and the low end face edge of top blind flange 1 is fixedly connected with snap ring 7, lid 2 Inner upper end be fixedly installed with barrier ring 6.

Plastic flexible pipe 9 positioned at least significant end is fixedly connected with the closed phase of the inner tip of lid 2, positioned at the plastics of top Hose 9 is mutually fixedly connected with the low side face of top blind flange 1, and connecting portion is located at the inside of snap ring 7, and folded tube 4 is pushed up when shrinking Portion's cover board 1 realizes by the inside that snap ring 7 is connected to fixed card slot 5 and combines with lid 2 that the low side of barrier ring 6 is fixedly connected There is rubber seal, and the blocking of barrier ring 6 folded tube 4 enters to the inside of lid 2 when the contraction of folded tube 4, the surrounding of lid 2 is opened Equipped with antiskid thread, snap ring 7 is rubber system, and the inside two sides of fixed card slot 5 are inlaid with rubber pad, snap ring 7 and fixed card slot 5 It is adapted.

Working principle: being mutually threadedly coupled using the fillet of screw 3 with plastic barrel in use process by twisting lid 2, in modeling bucket When staving is squeezed during transporting liquid, internal liquid will receive opening and bung of the pressure to staving top Place's movement, a large amount of liquid moment are moved to the pressure that formation is very big at bung, and liquid can be by snap ring 7 by fixed card slot 5 at this time Inside rush open separation, top blind flange 1 can generate displacement straight up at this time, and in fluid pressure and top blind flange 1 Lower folded tube 4 is pulled to be opened by folded state, liquid can enter to the inside of folded tube 4, thus effectively slow down staving by External force squeezes the generation for causing internal liquid splash phenomena, the pressure that can generate liquid when folded tube 4 is opened by folded state Moment slows down, and effectively prevents the generation for causing expulsion events in transportational process due to being squeezed liquid, the lid after stretching, extension The plastic flexible pipe 9 in folded tube 4 need to only be folded by pressing folded tube 4 when body is withdrawn, pass through pressing top after folding The inside that snap ring 7 is stuck in fixed card slot 5 can be realized the folded state of lid by cover board 1, and by 4 foldable integral of folded tube Barrier ring 6 can obstruct the spring ring 8 in folded tube 4 when folding and unfolding is between top blind flange 1 and lid 2, effectively prevent The inside that folded folded tube 4 enters to lid 2, which engages the fillet of screw 3 with the screw thread of bung hole, to be impacted.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
