Description
Technical field
The utility model relates to the pipe fitting technical field, especially a kind of plastic-aluminum combined effective clamp-press type pipe.
Background technique
Existing a kind of plastic-aluminum combined effective clamp-press type pipe, as shown in Figure 1, this pipe fitting is made up of pipe fitting body 11, plastics back-up ring 12, chuck 13 and two O-ring seals 14, the core body cylindrical that pipe fitting body 11 joins with tubing is provided with two seal grooves 111, many zigzag fashion annular grooves 112 and back-up ring positioning ring groove 113, and the tubaeform port one 31 of chuck 13 snaps in the ring groove 121 of plastics back-up ring 12.There is following some deficiency in this pipe fitting: when installed (1), to exist certain tolerance, core body to push in the tubing endoporus process two seal rings bigger sometimes with the frictional force of pipe material inner wall because pipe fitting cooperates with tubing, installs than requiring great effort; (2) acute angle of zigzag fashion annular groove 112 is bigger to the contact stress of joint tubing internal layer, damages the tubing internal layer easily, and the long term seal performance is had certain influence.
Summary of the invention
The utility model is for solving above-mentioned existing in prior technology deficiency, and a kind of laborsaving convenience, clamp-press type pipe that long term seal is good installed is provided.
Technical solution of the present utility model realizes in the following way: a kind of clamp-press type pipe, comprise body 21, seal ring 22, chuck 23, the anterior cylindrical of the core body of body 21 is provided with 1～4 waveform annular groove 211, core body middle part cylindrical is provided with a seal groove 212, many ring tongues 213 and ring groove 214, core body afterbody cylindrical is provided with location tongue 215, positioning groove 216, also be provided with positioning ring 24, this positioning ring 24 tightly is enclosed within the positioning groove 216; The tail end of described chuck 23 inwardly is provided with flange hole 231, the external diameter after the diameter in this flange hole 231 is installed less than positioning ring 24, and the tail end of chuck 23 tightly is stuck on the positioning ring 24; The degree of depth of described waveform annular groove 211 is slightly less than the degree of depth of ring groove 214; The cross section of described ring tongue ring 213 and ring groove 214 is a rectangle or trapezoidal.
Compared with prior art, the utlity model has following beneficial effect: (1) pipe fitting and tubing connection are convenient, and be time saving and energy saving; (2) core body does not have the zigzag fashion acute angle, and is less to the damage of tubing joint internal layer, and waveform annular groove 211 structures have improved sealability simultaneously, thereby have improved pipe fitting long term seal performance.

Fig. 2 is the utility model embodiment pipe fitting sectional arrangement drawing.
Fig. 3 is the exploded view of the utility model embodiment pipe fitting.
Embodiment
Referring to Fig. 2, shown in Figure 3, a kind of clamp-press type pipe of present embodiment is by body 21, seal ring 22, chuck 23, and positioning ring 24 is formed.The connecting end core body of body 21 is straight tube shape, the anterior cylindrical of core body is provided with 2 waveform annular grooves 211, core body middle part cylindrical is provided with a seal groove 212, many ring tongues 213 and ring groove 214, core body afterbody cylindrical is provided with location tongue 215, positioning groove 216, and positioning ring 24 tightly is enclosed within the positioning groove 216;
Positioning ring 24 is a rubber o-ring, is provided with peep hole 232 near the tail end of chuck 23, and tail end inwardly is provided with flange hole 231, the external diameter after the diameter in flange hole 231 is installed less than positioning ring 24, and chuck 23 can securely be stuck on the positioning ring 24, and its method is; There is an end of peep hole 232 to push positioning ring 24 to chuck 23, firmly screws in and block positioning ring 24 until flange hole 231.
The degree of depth of waveform annular groove 211 is slightly less than the degree of depth of ring groove 214;
The cross section of ring tongue ring 213 and ring groove 214 is a rectangle.
The utility model can be applicable to above straight-through, the elbow of any end or an end, tee pipe fitting.
The utility model connects the aluminium-plastic composite pipe except that being applicable to, also waits other flexible pipe applicable to connecting the PEX pipe.
