Description

A kind of connecting head

Technical field

The utility model belongs to pipe fitting interconnection technique field, especially relates to a kind of connecting head of connection pipe fitting.

Background technique

The method that connects between the general pipe fitting has three kinds, and a kind of is that the pipe fitting that directly two needs is linked to each other welds together, and welds cumbersome; Waste time and energy; The energy that needs labor just can not be dismantled in case connect, and can not be used for the connection between the plastic pipe.

Second kind is to realize the interconnection between the pipe fitting through threaded connecting head, all is provided with screw thread on the two ends of connecting head, and corresponding then pipe fitting is fixed on the two ends of connecting head through being spirally connected, just accomplished the interconnection of pipe fitting.This mode must be processed with screw thread and can realize interconnection on the end of pipe fitting, and is spirally connected and fixing also relatively expends time in.

The third is to realize the interconnection between the pipe fitting through the connecting head of band attachment hole; Pipe fitting is plugged on the interconnection that realizes in the attachment hole between the pipe fitting; This mode, connect fairly simple, but to the required precision of attachment hole than higher; If precision is not enough, or can causes pipe fitting to connect the pine pipe fitting and can't insert in the attachment hole at all.

Summary of the invention

The utility model provides a kind of connecting head to deficiency of the prior art, and is easy to connect and precision do not had very high requirement.

For solving the problems of the technologies described above; The utility model is able to solve through following technical proposals: a kind of connecting head, comprise body and plug connector, and said body is provided with lug boss; The groove that said plug connector is provided with axial through hole and communicates with said through hole; Said lug boss inserts said through hole, has 2 points on the said through-hole wall at least, and the distance before assembling between these 2 is less than the distance between 2 on the contacted said lug boss with it.During use, earlier plug connector is inserted in the pipe fitting that will connect, an end that again lug boss is not provided with groove on the plug connector inserts through hole; Have at least back down through-hole wall on the lug boss at 2, make the outside spreading of outer wall of plug connector to hold out against pipe fitting inner wall; Make pipe fitting link to each other with plug connector, simultaneously, plug connector is connected on the body through lug boss; On the body a plurality of lug bosses can be set, also just can a plurality of pipe fittings be connected on the same body, accomplish the connection between the pipe fitting.This mode of employing spreading of plug connector, the scope of its dimensional changes is very big, therefore precision is not had very high requirement.

In the technique scheme; Preferably, said through hole is a taper hole, and the front end of said lug boss is a round platform; Said round platform is fixed on the said body through attachment post; The diameter of said attachment post is less than or equal to the maximum diameter of round platform, and said through-hole wall has a ring cross-section, and the diameter in this cross section is less than the diameter of contacted round platform with it before assembling.Taper hole relatively is convenient to processing, and the diameter of taper hole reduces to a side gradually, and the degree of depth of inserting along with lug boss increases gradually, and the degree by spreading of plug connector strengthens gradually, therefore can cooperate with different pipe fittings through the spreading degree of regulating plug connector.The lug boss Front-end Design becomes the shape of round platform to be convenient to insert, and the area of contact between round platform and the taper hole is maximum, after the insertion, is not easy between plug connector and the lug boss to throw off.

In the technique scheme, preferred, an end of said plug connector is provided with and stops circle, stops that the diameter of circle is greater than the diameter of bore of the pipe fitting that matches with plug connector.Stop and to prevent that plug connector from falling in the pipe fitting endoporus.

In the technique scheme, preferred, also comprise sleeve pipe, said sleeve pipe and said body by integral forming.Sleeve pipe is used to cover the cooperation place of pipe fitting and plug connector, makes the utility model appearance seem more neat and artistic.

The plan of establishment of another kind of sleeve pipe is that said sleeve pipe is spirally connected and is fixed on body.

The beneficial effect of the utility model is: the inwall that utilizes the plug connector spreading to hold out against pipe fitting is realized being connected between plug connector and the pipe fitting; A plurality of then plug connectors are connected on the body; Realize the connection of a plurality of pipe fittings; Easy to connect, and the scope of the dimensional changes of plug connector is very big, therefore not to precision by very high requirement.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

Embodiment 1, referring to Fig. 1 and Fig. 2, and a kind of connecting head; Comprise body 1 and plug connector 2; Body 1 is a cylindrical body, and the two ends of body 1 are provided with

lug boss

11,12, the groove 22 that plug connector 2 is provided with axial hole 21 and communicates with through hole 21; Lug

boss

11,12 inserts through hole 21; Lug

boss

11,12 and through hole 21 can be Any shape, have 2 points on through hole 21 inwalls at least as long as satisfy, and the distance before assembling between these 2 is less than the distance between 2 on the contacted

lug boss

11,12 with it.Concrete; The front end of the

lug boss
