Description

Negative pressure quick connector not easy to fall off

Technical Field

The utility model belongs to the technical field of water pipe head, in particular to negative pressure that is difficult for droing connects soon, is particularly suitable for the water diversion joint of hot-water heating blanket.

Background

The water pipe head, no matter bi-pass, tee bend, cross, eight lead to connect, when it connects with water piping connection, all need guarantee the leakproofness of connecting to the joint of hot-water heating blanket is taken as an example, and the characteristics that hot-water heating blanket connects are generally that the link is many and the aperture is less, and the workman's operation of being not convenient for generally adopts to beat to glue or nut seal cover is connected to guarantee sealing performance, and production efficiency is lower, and is more extravagant artifical, and beats gluey mode also environmental protection.

SUMMERY OF THE UTILITY MODEL

The utility model provides a negative pressure that is difficult for droing connects soon can solve the problem that points out among the background art.

The utility model provides a negative pressure that is difficult for droing connects soon, includes and connects the body, it has two at least links to connect the body, and wherein at least one link includes inner tube and outer tube, be the intubate clearance between inner tube and the outer tube, intubate clearance inboard one end is enclosed construction, the inner tube is the toper pipe.

Has the advantages that: the utility model provides a negative pressure that is difficult for droing connects soon inserts plastic hose in the intubate clearance, inserts the back that targets in place, can accomplish the high-speed joint, and under the condition of not beating glue, not using the seal cover, is difficult for droing, connects very fast, improves connection efficiency greatly, reduces the cost of labor, and the environmental protection is harmless.

Detailed Description

In the following, an embodiment of the present invention will be described in detail with reference to the drawings, but it should be understood that the scope of the present invention is not limited by the embodiment.

Example 1:

as shown in fig. 1, a negative pressure quick connector that is not easy to fall off includes a connector body 1, the connector body 1 has at least two connection ends 2, as shown in fig. 1, in this embodiment, the connection ends 2 are two, that is, the embodiment is a two-way connection connector, and both the connection ends 2 include an inner tube 21 and an outer tube 22, the inner tube 21 is used for communicating water, of course, according to actual use needs, one connection end 2 may also include the inner tube 21 and the outer tube 22, the other is a common connection end, an insertion tube gap 23 is formed between the inner tube 21 and the outer tube 22, and one end inside the insertion tube gap 23 is a closed structure.

Inner tube 21 is the conical duct, and the conical duct is convenient for insert, and along with male going on, the aperture crescent of conical duct just so can guarantee the leakproofness between plastic hose 3 and inner tube 21 and the outer tube 22, the assurance intubate clearance 23 depths that can be better forms sealed environment.

Example 2:

as shown in fig. 2, the present embodiment provides a four-way connection joint, i.e. having four connection ends 2, and the connection ends 2 include an inner tube 21 and an outer tube 22.

Example 3:

as shown in fig. 3, the present embodiment provides an eight-way joint, i.e. having eight joint ends 2, the joint ends 2 including an inner tube 21 and an outer tube 22.

The utility model discloses a theory of operation: the utility model is suitable for a connection of plastic hose 3, the plastic hose 3 of hot-water heating blanket generally all can be suitable for, as shown in fig. 4, insert plastic hose 3 in intubate clearance 23, it is motionless to insert, at this moment plastic hose 3 pegs graft and targets in place, because plastic hose 3 has better pliability, it pegs graft and targets in place the back, can have certain deformation, thereby guarantee the leakproofness between plastic hose 3 and inner tube 21 and outer tube 22, thereby make the depths of intubate clearance 23 form very little enclosure space 4, in the grafting process, because plastic hose 5 does not reach closely to paste with inner tube 21 and outer tube 22 and lean on, the air in enclosure space 4 is outwards discharged by the gap, so wait to peg graft and target in place the back, the atmospheric pressure in enclosure space 4 is equivalent to external environment atmospheric pressure, at this moment outwards extract plastic hose 3, it is extremely difficult to be extracted;

the principle is as follows: the plastic hose 3 tries to be pulled out outwards, the space of the closed space 4 tries to be increased, negative pressure is tried to be formed in the closed space 4, and therefore the plastic hose 3 is extremely difficult to pull out.

The inner tube 21 and the outer tube 22 also give a certain frictional force to the plastic hose 3, so that it is not easily pulled out.

The above disclosure is only for a few specific embodiments of the present invention, however, the present invention is not limited to the embodiments, and any changes that can be considered by those skilled in the art shall fall within the protection scope of the present invention.
