Abstract
The invention provides a connecting pipe fitting, which comprises a pipe shell. The connecting pipe fitting is characterized in that: annular alternate bumps are reserved in the middle of the inner surface of the pipe shell; latch grooves are respectively reserved on end parts of four corners of the inner surface of the pipe shell; and a seal ring groove is reserved on each side of each latch groove. According to the connecting pipe fitting, the problems of complex connecting operation and labor and time waste of a current plastic pipe fitting can be solved, and the connecting pipe fitting is suitable for plastic pipeline connection.
Description
Technical field
The present invention relates to the interface unit field of plastic tube, a kind of specifically pipe fitting that connects plastic tube.
Background technique
At present, the Placement of plastic tube mainly contains hot melten type, needs with the hot-melting machine of different size tubing and pipe fitting hot melt to be handled the back connection; Cold jointing type is also arranged, and is exactly to connect with viscose glue, viscose glue is smeared evenly the back is connected on outer pipe wall and the pipe fitting inner wall, and it is just effective after consolidating that viscose glues such as need are hard.No matter be hot melten type or cold jointing type, construction environment required high, need the professional and technical personnel to pass through the special tool operation, complex operation, time-consuming, the human operational error is prone to the shortcoming that causes tie point to leak.
Summary of the invention
The present invention provides a kind of connection pipe fitting that has space protrusion and groove structure for solving loaded down with trivial details, the time-consuming problem of attended operation of present plastic tube.
Technological scheme of the present invention is that a kind of connection pipe fitting comprises the pipe fitting housing; Its special way is; Ring-like space protrusion is left at pipe fitting shell inner surface middle part, and four jiaos of ends of pipe fitting shell inner surface are left the locking plate groove respectively, and each locking plate groove both sides is left o-ring groove respectively.
During use; The formula band tooth locking reed of beginning to speak at first is installed in the locking plate groove; Seal ring is installed in the o-ring groove, then tubing one end is firmly inserted in the pipe fitting housing, make tubing pass the first road seal ring, the formula of beginning to speak band tooth locking reed and the second road seal ring in the pipe fitting housing respectively; Till extremely can't continuing to insert, accomplish effectively connection.The seal ring distortion that is squeezed can evenly be clogged in the space between tubing and pipe fitting housing, plays the effect that sealing blocks water.The teeth of the formula of beginning to speak band tooth locking reed can embed the outer wall of tubing under the effect of elastic force and tensile force, tubing is locked.The main effect of beginning to speak is in the installation process, begins to speak through tightening up, and can dwindle the external diameter of the formula band tooth locking reed of beginning to speak, and it is sent in the locking plate groove in the pipe fitting housing smoothly, accomplishes assembling.
Technique effect of the present invention is, adopt technique scheme can realize a kind of simple to operate, connect tube connection piece fast.
Description of drawings
Fig. 1 is a structural front view of the present invention, and the accompanying drawing that makes an abstract.
In the drawings, 1 begin to speak formula band tooth locking reed, 2 seal rings, 3 o-ring grooves, 4 locking plate grooves, 5 space protrusion, 6 tubing, 7 pipe fitting housings.
Embodiment
Embodiment further specifies the present invention below in conjunction with accompanying drawing.
Shown in figure, ring-like space protrusion 5 is left at pipe fitting housing 7 internal surfaces middle part, and four jiaos of ends of pipe fitting housing 7 internal surfaces are left locking plate groove 4 respectively, and each locking plate groove 4 both sides is left o-ring groove 3 respectively.
During use; The formula band tooth locking reed 1 of beginning to speak at first is installed in locking plate groove 4; Seal rings 2 are installed in the o-ring groove 3, then tubing 6 one ends are firmly inserted in the pipe fitting housing 7, make tubing 6 pass the first road seal ring 2, the formula of beginning to speak band tooth locking reed 1 and the second road seal ring 2 in the pipe fitting housing 7 respectively; Till extremely can't continuing to insert, accomplish effectively connection.Seal ring 2 distortion that is squeezed can evenly be clogged in the space of 7 of tubing 6 and pipe fitting housings, plays the effect that sealing blocks water.The teeth of the formula of beginning to speak band tooth locking reed 1 can embed the outer wall of tubing 6 under the effect of elastic force and tensile force, with tubing 6 lockings.The main effect of beginning to speak is in the installation process, begins to speak through tightening up, and can dwindle the external diameter of the formula band tooth locking reed 1 of beginning to speak, and it is sent in the locking plate groove 4 in the pipe fitting housing 7 smoothly, accomplishes assembling.
Claims (1)
1. a connection pipe fitting comprises the pipe fitting housing, it is characterized in that: ring-like space protrusion is left at pipe fitting shell inner surface middle part, and four jiaos of ends of pipe fitting shell inner surface are left the locking plate groove respectively, and each locking plate groove both sides is left o-ring groove respectively.
