Abstract
The utility model provides a water resistance tube with a metal head easily fixed on a tube body. The water resistance tube comprises the tube body and the metal head, wherein an inner cavity is formed in the metal head and penetrates through the metal head; the metal head is provided with a lower connecting part, a middle connecting part and an upper connecting part; at least one groove is formed in the middle connecting part, and a groove-shaped port communicated with the inner cavity is formed in the groove; the upper connecting part adopts a flat top surface, a pipe orifice communicated with the inner cavity is formed in the central position of the flat top surface; a plurality of lugs used for mounting and positioning the tube body in the inner cavity are arranged at the pipe orifice, and a plurality of hollow notches are formed among the lugs; and the middle connecting part and the upper connecting part are connected with the tube body, and a plastic part is injected at the middle connecting part and the upper connecting part. By means of the groove-shaped port and the hollow notches, the connecting tightness of the tube body and the metal head in the injection molding process of the plastic part is enhanced, the structure is simple, and the problem that the metal head is prone to separate from the tube body is completely solved.
Description
Technical field
The utility model relates to water resistance pipe field, relates in particular to the water resistance pipe that a kind of body is easy to fixing metal head.
Background technology
Utilize the water resistance pipe that resistance effect that water self has is made into be widely applied in electric heater, it is that current form resistance in body by a thin and long pipe structure, thereby eliminates the electric current in water.
Traditional water resistance pipe as shown in Figure 1, one end of body 1 is installed one and is with externally threaded ferrule 2, contact position place between body 1 and ferrule 2 is by sealing ring 3 restriction current seepages, the end that this ferrule 2 is fixed in one plastic body 4 injection mouldings makes external screw thread connect for outer connected nut, but, body 1 be take straight tube as main, body 1 with the connection bit of ferrule 2 owing to there is no being connected of miscellaneous part, the as easy as rolling off a log body 1 that makes gets loose from ferrule 2, bring when mounted great trouble to people, people usually blame for, body 1 easily gets loose and need to change water resistance pipe with ferrule 2.
Utility model content
The water resistance pipe that the utility model provides a kind of body to be easy to fixing metal head, its object is to solve the problem that body easily gets loose from ferrule.
To this, the utility model comprises: body and ferrule, in this ferrule, be provided with and connect inner inner chamber, ferrule have lower connecting part, in connect portion and upper connecting part, wherein, in described, the portion of connecing is provided with at least one groove, this groove is provided with the flute profile mouth being communicated with inner chamber, described upper connecting part is a flat top surface, the middle position of this flat top surface is provided with the mouth of pipe being communicated with inner chamber, this mouth of pipe is provided with several makes body be installed on the projection of location in inner chamber, is provided with several vacancy mouths between projection and projection, meets portion and upper connecting part associating body the same plastic cement portion that is injected with in this.
The number of described projection is three, and this vacancy mouth is three.
Described projection and vacancy mouth are arranged in circle shape along the inwall of the mouth of pipe successively.
Described groove is toroidal, and number is two.
The outer edge position of described upper connecting part is provided with the recess that several are connected with ferrule for increasing body.
The periphery of described lower connecting part is along being provided with threaded portion.
The beneficial effects of the utility model are: by be provided with the flute profile mouth being communicated with inner chamber at groove, the mouth of pipe is provided with the projection that makes body be installed on location in inner chamber, and between projection and projection, be provided with several vacancy mouths, flute profile mouth increased with vacancy mouth plastic cement portion in injection moulding process to the tightness being connected between body and ferrule, it is simple in structure, overcomes the problem that ferrule and body easily depart from completely.
Accompanying drawing explanation
Fig. 1 is traditional water resistance pipe schematic diagram.
Fig. 2 is the cutaway view of the utility model preferred embodiment.
Fig. 3 is the stereogram of the ferrule of the utility model.
Fig. 4 is the schematic diagram that body and ferrule are installed.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model will be further described, as Fig. 2, Fig. 3, the preferred embodiment of the shown the utility model of Fig. 4, it comprises body 1 and ferrule 2, in this ferrule 2, be provided with and connect inner inner chamber 3, ferrule 2 has lower connecting part 21, in connect portion 22 and upper connecting part 23, wherein, the periphery of lower connecting part 11 is along being provided with threaded portion 7, in described, meet portion 22 and be provided with at least one groove 4, this groove 4 is provided with the flute profile mouth 41 being communicated with inner chamber 3, described upper connecting part 13 is a flat top surface, the middle position of this flat top surface is provided with the mouth of pipe 24 being communicated with inner chamber 3, this mouth of pipe 24 is provided with several makes body 1 be installed on the projection 5 of inner chamber 3 interior location, between projection 5 and projection 5, be provided with several vacancy mouths 51, in this, meet portion 22 and upper connecting part 23 associating bodys 1 the same plastic cement portion 6 that is injected with.
In concrete production process, the number of described projection 5 is three, and this vacancy mouth 51 is three, and projection 5 is arranged in circle shape along the inwall of the mouth of pipe 24 successively with vacancy mouth 51.Meanwhile, this groove 4 is toroidal, and number is two, and the outer edge position of upper connecting part 23 is provided with several recesses 25 being connected with ferrule 2 for increasing body 1.
Because recess 25 and vacancy mouth 51 are to be communicated with inner chamber 3, when body 1 is installed in this inner chamber 3 from the mouth of pipe 24, this plastic cement portion 6 of injection moulding again, plastic cement fluid is being filled body 1 and ferrule 2 lower connecting part 21 inwalls, recess 25,51 outputs of vacancy mouth from being communicated with inner chamber 3 again, make plastic cement fluid wrap up this projection 5 and groove 4 completely, finally plastic cement fluid is fixedly cooled to the shape needing, finally realize the object being fastenedly connected of body 1 and ferrule 2.
Above-mentioned specific embodiment is only the good specific embodiment of the utility model effect, and all bodys identical with this structure or that be equal to are easy to the water resistance pipe of fixing metal head, all in the application's protection domain.
