Description

Plastic hose discharge end hermetically-sealed construction

Technical field

The utility model relates to a kind of plastic hose that can be used for carrying liquid or lotion material, and is special relevant with the hermetically-sealed construction of plastic hose discharge end.

Background technology

Flexible pipe has in light weight, uses and convenient carrying, and application is extensive; Can be used for cosmetics, daily necessities and medical packaging etc., its structure is normally by body and cooperate the pipe lid of the body mouth of pipe to constitute, and opens the pipe lid during use; The extruding body is taken material, and after stopping to push, outside air can get in the body by suck-back along with the recovery of soft body; Or the material of having extruded body passes back in the body again; Material is caused oxidation or pollution, do not meet the requirement of health, this case produces thus.

The utility model content

In view of this, the utility model provides a kind of plastic hose discharge end hermetically-sealed construction, can strengthen the leak tightness of discharge end, prevents to push the back outside air and pours in down a chimney and feed back.

For reaching above-mentioned purpose, the technical solution of the utility model is:

A kind of plastic hose discharge end hermetically-sealed construction includes the mouth of pipe, packing seal, end plug and the Guan Gai of plastic hose body; Moulding one interval in the mouth of pipe of said body, the middle part at this interval are provided with and are communicated with body in-to-in discharge opening; Said packing seal is located in the mouth of pipe, forms with discharge opening to cooperate, and it adopts soft silica gel material to process, the block face that the corresponding discharge opening formation of sealing pad one is big than the discharge opening aperture; Said end plug flush fit is located on the mouth of pipe of body, has the open cavity volume in bottom, and the end face of end plug provides the material hole of a connection cavity volume; Said pipe lid forms with the mouth of pipe of body and cooperates, and protrudes the plug of a cooperation end plug material hole on its end face.

The sealing pad is provided with ring flange.

This end plug bottom outer wall is provided with convex tendon, and above convex tendon, forms a limiting block edge, and the inwall of end plug is provided with the catch of fitted seal gasket ring flange again.

Adopt said structure; Because the utility model is provided with packing seal on the mouth of pipe of plastic hose discharging; Utilize the characteristic of packing seal material; The sealing effectiveness of flexible pipe discharge end can be guaranteed, and after stopping to push, outside air can be stoped and the safety and the health of material in guaranteeing to manage are gone in the body in the feed back that rests in the end plug cavity volume.

The specific embodiment

Below through specific embodiment and conjunction with figs. the utility model is elaborated.

To shown in Figure 3, a kind of plastic hose 10 includes body 1, packing seal 2, end plug 3 and pipe and covers 4 compositions like Fig. 1.

The top of said body 1 is the mouth of pipe 11, is equipped with screw thread 12 on the outer wall of the mouth of pipe 11, and the nearly mouth of pipe of the inwall of the mouth of pipe 11 place's moulding one interval 13; The middle part at this interval 13 is provided with and is communicated with body 1 in-to-in discharge opening 14, and said packing seal 2 is located in the mouth of pipe 11, forms with discharge opening 14 to cooperate; Be to adopt soft silica gel material to process; Sealing pad 2 is provided with ring flange 21, and the below of ring flange 21 forms a block face 22 big than the discharge opening aperture, can corresponding sealing discharge opening 14 by this block face 22; Said end plug 3 flush fits are located on the mouth of pipe 11 of body 1, are in the top of packing seal 2, and it has the open cavity volume 31 in bottom; The end face of end plug 3 provides the material hole 32 of a connection cavity volume 31; Material hole 32 communicates with the discharge opening 14 of body through cavity volume 31, and the end plug bottom outer wall is provided with convex tendon 33, and above convex tendon 33, forms a limiting block edge 34; Convex with catch 35 on end plug cavity volume 31 inwalls again; End plug 3 when installing be adopt suppress make end plug 3 convex tendon 33 through the mouth of pipe, in the mouth of pipe that is tightly fixed, retaining edge 34 blocks that make this end plug 3 after the installation are in the mouth of pipe; And the bottom of end plug catch 35 holds the ring flange 21 of packing seal 2, and packing seal 2 is stabilized on the discharge opening 14; Said pipe lid 4 is provided with the thread segment 41 that cooperates with the mouth of pipe 11 screw threads 12, and a pair of plug 42 that should cooperate end plug material hole 32 of protrusion on the end face.

As shown in Figure 4; The pipe of screwing covered 4 o'clock; Pipe cover 4 thread segment 41 and is screwed into along mouth of pipe screw thread 12, and makes pipe cover the material hole 32 of the plug 42 sealing end plugs at 4 tops, and the interior discharge opening 14 of body receives the capping of packing seal 2 block faces 22 at this moment; Blocked the passage that material flows out in the body 1, the material that this moment, body received in any extruded tube can not overflow from material hole.

As shown in Figure 5, open pipe during use and cover 4, push body, the block face 22 of packing seal 2 receives interior the pushing elastic deformation of material of body and opens discharge opening 14 at this moment, and the material in the body can be by the material hole 32 outflow confession uses of discharge opening 14 through end plug 3; After stopping extruding, as shown in Figure 6,22 elastic recovery shutoff of block face discharge opening 14 of packing seal 2 can stop outside air and rest on the 31 interior feed backs of end plug 3 cavity volumes and go into material in the body 1 internal contamination pipe.

But the key of said structure knowledge capital utility model is the setting of packing seal; And the characteristic of combination seal pad material; Can guarantee the sealing effectiveness of flexible pipe discharge end; And after stopping to push, can stop outside air and the safety and the health of material in guaranteeing to manage are gone in the body in the feed back that rests in the end plug cavity volume.
