For example, Chinese patent literature discloses a kind of conduit fast connection structure [application number: 200820060571.4], be included in the outer side surface moulding outside thread of a tubular body, one collar inner side surface moulding internal thread, the collar, with the external thread spiro fastening of internal thread and body, makes the collar when body rotates, and can make to overlap the axial displacement of hoop body, in the time of in water pipe is inserted in body, the location that can be got loose to water pipe by the axial displacement of the collar.
Above-mentioned two schemes has strengthened the practicability of existing pipe joint to a certain extent, and still, this two schemes at least also exists following defect: design unreasonable, inconvenience is installed and install after easily loosening, the poor stability of tie point, cannot meet usage requirement.
Model utility content
The purpose of this utility model is for the problems referred to above, provides a kind of design more rationally and the brass connecting head of the cooling/heating device being convenient to install.
For achieving the above object, the utility model has adopted following technical proposal: the brass connecting head of this cooling/heating device comprises that center has the joint body of circulation passage, it is characterized in that, described joint body comprises the outer-hexagonal section of setting placed in the middle, axial centre one end in outer-hexagonal section has tapered linkage section, described linkage section stub end and outer-hexagonal section are connected and have rapid pipe joint at the little head end of linkage section, between described outer-hexagonal section and linkage section, be provided with annular slot to make way, the described outer-hexagonal section the other end has cylinder, described cylinder shaft axis overlaps with outer-hexagonal section axis line, at cylinder inwall, be shaped with internal spline, the number of teeth of this internal spline is 16-28 tooth, in cylinder, away from one end inwall of outer-hexagonal section, be provided with ring-shaped step, described cylinder external diameter is greater than the external diameter of linkage section stub end.
In this application, outer-hexagonal section is convenient to the control for dismounting and installation, the effect of tapered linkage section, rapid pipe joint, annular slot to make way, internal spline is to improve installation efficiency, guarantee stability and the fixing of mounted configuration, in addition, ring-shaped step is used for installing seal ring, guarantees the sealing of tie point.
In the brass connecting head of above-mentioned cooling/heating device, the length of described outer-hexagonal section is the 2-3 multiple of cylinder length.
In the brass connecting head of above-mentioned cooling/heating device, the length of described outer-hexagonal section is 1-2 times of linkage section length.
In the brass connecting head of above-mentioned cooling/heating device, described cylinder has annular guide surface away from one end of outer-hexagonal section.
Compared with prior art, the advantage of the brass connecting head of this cooling/heating device is: 1, design is more reasonable, outer-hexagonal section is convenient to the control for dismounting and installation, the effect of rapid pipe joint, annular slot to make way, internal spline is to improve installation efficiency, guarantee stability and the fixing of mounted configuration, in addition, ring-shaped step is used for installing seal ring, guarantees the sealing of tie point; 2, join strength is high, guarantees working life.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model provides.
In figure, joint body 1, circulation passage a, annular guide surface b, annular slot to make way 1a, outer-hexagonal section 11, linkage section 12, rapid pipe joint 13, cylinder 14, internal spline 14a, ring-shaped step 15.
Embodiment
Be below the specific embodiment by reference to the accompanying drawings of model utility, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, the brass connecting head of this cooling/heating device comprises that center has the joint body 1 of circulation passage a, optimized project, the joint body 1 of the present embodiment comprises the outer-hexagonal section 11 of setting placed in the middle, axial centre one end in outer-hexagonal section 11 has tapered linkage section 12, described linkage section 12 stub ends and outer-hexagonal section 11 is connected and have rapid pipe joint 13 at the little head end of linkage section 12, between described outer-hexagonal section 11 and linkage section 12, be provided with annular slot to make way 1a, described outer-hexagonal section 11 the other ends have cylinder 14, described cylinder 14 shaft axiss overlap with outer-hexagonal section 11 axis lines, at cylinder 14 inwalls, be shaped with internal spline 14a, the number of teeth of this internal spline 14a is 16-28 tooth, in cylinder 14, away from one end inwall of outer-hexagonal section 11, be provided with ring-shaped step 15, described cylinder 14 external diameters are greater than the external diameter of linkage section 12 stub ends.
