Detailed Description

The present invention will be described in detail with reference to the accompanying drawings in which embodiments of the invention are shown.

Referring to fig. 4-6, there are shown schematic views of embodiments of the present invention that can increase the sealability at the junction of the valve body 101 and the plastic tube by means of extrusion deformation of the plastic tube, and further,

the utility model provides a connecting valve, includes valve body 101, two connecting pipes 102 of welded fastening connection on the valve body 101, equal welded fastening connection has the bevel cover 103 and keeps off cover 104 on two connecting pipes 102, all through two support frames 302 of bolt fixedly connected with on two keep off cover 104, equal fixedly connected with thread bush 301 in the middle of every support frame 302, all be connected with sleeve pipe 201 through screw thread 202 on two thread bush 301, a plurality of rubber rings 203 of fixedly connected with all bond in two sleeve pipe 201.

When the valve body 101 is connected with a plastic pipe, the plastic pipe is firstly inserted into a gap between the sleeve 201 and the connecting pipe 102, then the inclined sleeve 103 and the plastic pipe are forcibly extruded, the plastic pipe is sleeved on the inclined sleeve 103, the port of the plastic pipe is deformed and is wrapped on the inclined sleeve 103, the plastic pipe and the inclined sleeve 103 are in interference fit at the moment, the sealing performance of the joint between the plastic pipe and the connecting pipe 102 can be improved, at the moment, the sleeve 201 is rotated, the sleeve 201 is connected with the threaded sleeve 301 through the threads 202, the sleeve 201 gradually moves towards the inclined sleeve 103, when the sleeve 201 is close to the inclined sleeve 103, the gap between the sleeve 201 and the inclined sleeve 103 can be gradually reduced, the extrusion effect on the wall of the plastic pipe is generated, the sealing performance between the plastic pipe and the connecting pipe 102 is further improved, the plurality of rubber rings 203 in the connecting pipe 102 play a role in improving the sealing performance, the gap between the connecting pipe 102 and the plastic pipe 102 can be filled, the liquid blocking effect is achieved, meanwhile, the friction force between the connecting pipe 102 and the plastic pipe is also increased, and the plastic pipe is not easy to separate.

Referring to fig. 5-6, there is shown a schematic view of an embodiment of the present invention that enables multiple rubber rings 203 within a sleeve 201 to be compressed, and further,

two sleeve pipe 201 one end is the toper uncovered, and when sleeve pipe 201 was close to inclined plane cover 103 gradually, sleeve pipe 201's toper uncovered can cooperate gradually with the inclined plane on the inclined plane cover 103 to reach the purpose that slowly reduces the gap between connecting pipe 102 and the plastic tubing, make a plurality of rubber rings 203 in the sleeve pipe 201 can receive the extrusion, play better sealed effect.

Referring to fig. 7-10, there is shown a schematic view of an embodiment of the present invention that enables the port ends of the plastic tube to be snugly received on the bevel of the bevel sleeve 103, and further,

all through bolt fixedly connected with balladeur train 503 on two support frames 302, equal sliding connection has two groove poles 502 on every balladeur train 503, all offers on every groove pole 502 to be used for cooperating the gliding groove of balladeur train 503, all through bolt fixedly connected with design cover 401 on every groove pole 502.

The design cover 401 is used for extruding and shaping the plastic pipe that has warp, after the connecting pipe 102 inserts the plastic pipe, the plastic pipe end contacts with the bevel sleeve 103 and produces the deformation, slide on two balladeur train 503 respectively through controlling upper and lower two groove poles 502 this moment, make two design covers 401 all be close to the port department of plastic pipe from top to bottom, after two design covers 401 lock, and then can extrude the design to the port department of plastic pipe, make the port department of plastic pipe can be tight paste on the inclined plane of bevel sleeve 103, thereby further guaranteed the leakproofness.

Referring to fig. 10, there is shown a schematic view of the effect of securing the firmness between the plastic pipe and the inclined surface sleeve 103 while enhancing the waterproofness according to the present invention, and further,

each shaping cover 401 is fixedly connected with a rubber extrusion pipe 403 through bolts.

Crowded rubber pipe 403 is used for extruding the adhesive to between design cover 401 and the plastic tubing, after two design covers 401 lock stereotype the plastic tubing about, the crowded rubber pipe 403 on two design covers 401 of staff's accessible is to extruding the adhesive between design cover 401 and the plastic tubing this moment, thereby make the adhesive spill over from design cover 401, bond between plastic tubing port department and inclined plane cover 103, when further improving waterproof nature, and can also guarantee the fastness between plastic tubing and inclined plane cover 103 under two design covers 401's pressfitting.

Referring to fig. 7-8, there is shown a schematic diagram of an embodiment of the present invention that provides a space for flash for the styling cap 401, and further,

a plurality of ribs 402 are provided in each shaped cap 401.

The plurality of ribs 402 provide a space for the sizing cover 401 to overflow, when the adhesive is extruded from the sizing cover 401, the adhesive can overflow along the gap formed by the plurality of ribs 402, and then the gap is filled, so that the adhesive can be distributed in the sizing cover 401.

Referring to fig. 9, there is shown a schematic view of an embodiment of the invention that ensures that the design cover 401 is disengaged from the ramp cover 103 under normal conditions, and further,

two elastic sheets 504 are fixedly connected between each slot rod 502 and the sliding frame 503 in a welding mode.

Under the elastic action of two shell fragments 504, the groove pole 502 drives the design cover 401 and breaks away from the bevel cover 103, when needs are stereotyped and glue is crowded, can make the groove pole 502 drive the plastic tubing that the design cover 401 extrudees on the bevel cover 103 through pressing down the groove pole 502, and two shell fragments 504 atress produce the bending simultaneously, and when the adhesive air-dried, design cover 401 was fixed on the bevel cover 103, and the groove pole 502 can not automatic re-setting.

Referring to fig. 9, there is shown a schematic view of an embodiment capable of facilitating power saving according to the present invention, and further,

two shifting rods 501 are rotatably connected to the two support frames 302 through shafts, and each shifting rod 501 is in contact with one slot rod 502.

When the sizing and glue squeezing needs to be carried out, a worker only needs to pull the upper and lower two shifting rods 501, so that the two shifting rods 501 respectively shift the two groove rods 502, the buckling function of the two sizing covers 401 is realized, and the function of convenience and labor saving is achieved.
