Abstract

The utility model provides a vacuum extruding clamshell tube which comprises a tube body and a clamshell, wherein the clamshell comprises an upper clamshell and lower clamshell which are connected with each other through a hinge; the top of the lower clamshell is provided with a liquid outlet hole to be matched with a sealing core on the upper clamshell in a sealing way; the outer side of the head of the tube is provided with a tube buttoning position or a tube screw thread; the center in the head of the tube is provided with a liquid outlet tube; the bottom of the liquid outlet tube and the head of the tube are connected with each other into a whole; the upper part of the liquid outlet tube is provided with a groove; the lower clamshell is internally provided with an inner clamshell and an inner plug; the inner side face of the inner clamshell is provided with a buttoning position or a screw thread to be buttoned with the corresponding tube buttoning position or screwed with the tube; the inner plug is matched with the inner wall of the head of the tube in a sealing way; an elastic body one-way valve is also arranged between the liquid outlet tube and the lower clamshell; the elastic body valve comprises a side part and a top part; and the side part is sheathed on the liquid outlet tube. The vacuum extruding clamshell tube can prevent air outside the tube from flowing back and prevent substances therein from being easily polluted and deteriorated, has simple structure, reliable function and low manufacture cost, and firstly realizes the vacuum extruding function of the clamshell hose.

Description

Vacuum is extruded and is renovated flexible pipe

Technical field

The utility model relates to a kind of vacuum and extrudes and renovate flexible pipe.

Background technology

The flexible pipe of renovating in the past is provided with fluid hole at the caping of its lower cover, opens that content and outside air can touch behind the upturning lid, and content in managing is polluted, and is perishable, thus the infringement consumer's interests.

Summary of the invention

The purpose of this utility model is to renovate the problems referred to above that flexible pipe exists at existing, but thereby provide a kind of air backflow resistent can avoid managing in content contact with outside air and the vacuum that goes bad is extruded and renovated flexible pipe.

The purpose of this utility model is achieved in that the utility model comprises body and renovates, described renovating comprises upturning lid and lower cover, upturning lid is connected by the folding knot with lower cover, be provided with at the top of lower cover and renovate fluid hole, be sealed and matched with the sealed core on the upturning lid, be provided with body button bit or body screw thread, be provided with drain pipe at the interior middle position of body head in the head of the described body outside, the bottom of drain pipe is connected with body head one, is provided with groove on the top of drain pipe; Be provided with inner cap and Nei Sai in the inside of described lower cover, be provided with button bit or screw thread is interlockingly connected or is threaded with body with corresponding body button bit at the medial surface of described inner cap, described in plug cooperate with the inner wall sealing of body head; Also be provided with the elastic body check valve between described drain pipe and lower cover, described elastic body check valve comprises sidepiece and top, and sidepiece is enclosed within on the drain pipe.

Technique effect of the present utility model is: the utility model adopts the elastic body check valve to realize that preventing to manage outer air refluxes, thereby the interior content of pipe is difficult for polluting and is rotten; The utility model adopts the elastic body check valve, and is simple in structure, reliable in function, and productive costs is low.The utility model is realized renovating the flexible pipe vacuum first and is extruded function.

Description of drawings

Fig. 1 is embodiment closes the state of lid at upturning lid a structural representation.

Fig. 2 is the structural representation of embodiment in the upturning lid open mode.

The specific embodiment

Referring to Fig. 1 and Fig. 2, present embodiment by body 1, renovate with thermoplastic elastomer check valve 5 and form, be provided with body button bit 12 in body head 11 outsides, interior middle position at body head 11 is provided with drain pipe 13, the bottom of drain pipe 13 is connected with the head one of body 1, is provided with groove 131 on the top of drain pipe 13; Renovate and comprise upturning lid 3 and lower cover 2, upturning lid 3 is connected by folding johning knot 4 with lower cover 2, be provided with at the top of lower cover 2 and renovate fluid hole 21, renovate fluid hole 21 upturning lid 3 close when covering state and upturning lid 3 on sealed core 31 be sealed and matched, be provided with inner cap 22 and Nei Sai 23 in the inside of lower cover 2, be provided with button bit 222 at the medial surface of inner cap 22 and be interlockingly connected with body button bit 12, play body 1 and renovate the effect of being connected and fixed, interior plug 23 cooperates with the inner wall sealing of body head 11; Thermoplastic elastomer check valve 5 is located between drain pipe 13 and the lower cover 2, and thermoplastic elastomer valve 5 comprises sidepiece and top, and sidepiece is enclosed within on the drain pipe 13 and seals groove 131.

The use and the principle of present embodiment are as follows: present embodiment is in body 1 behind the enclosing liquid, open upturning lid 3, the pipe shaft of extruding body 1, the sidepiece of thermoplastic elastomer check valve 5 distortion under squeese pressure, content from the groove 131 on drain pipe 13 tops flow to thermoplastic elastomer check valve 5 and drain pipe 13 the bottom and the fluid space between the interior plug 23 of lower cover 2, again outside renovating fluid hole 21 effusers.When losing squeese pressure, the sidepiece of thermoplastic elastomer check valve 5 recovers shape, be enclosed within again on the drain pipe 13, with drain pipe 13 and on groove 131 seal, the outer air of pipe can not be back in the pipe.

In the utility model lower cover and body be connected and fixed that also can adopting is threaded replaces button bit to be connected, promptly be provided with the body screw thread in the head outside of described body, be threaded with body at the inner side mounting thread of the inner cap of described lower cover.Lower cover is connected with the preferred button bit of being connected and fixed of body.

The check valve that the also available silica gel of thermoplastic elastomer check valve in the utility model (being the TPE valve) is made replaces.
