Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present specification, and not all of the embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the present specification without any inventive step should fall within the scope of protection of the present specification.

Referring to fig. 1 to 2, in an embodiment, the present application discloses a through type filter structure suitable for split processing, which includes a hollow tube 10 made of copper, having at least one opening 11;

the connector 20 is of a hollow structure, the surface of one end of the connector 20 is provided with an external thread 21, and the external thread 21 penetrates through the opening 11 and extends into the pipe body 10 to be in clearance fit with the pipe wall of the pipe body 10;

the filler 30 is melted and filled in the gap between the connector 20 and the pipe body 10 by a high frequency welding machine, and after being solidified, the connector 20 and the pipe body 10 are connected.

In the processing procedure of the penetration filter capable of being processed in a split mode, the external thread 21 end of the connector 20 is firstly installed at the opening 11 of the tube body 10, then the tin wire is used as the filler 30, the tin wire is filled in the gap between the external thread 21 and the opening 11, the tin wire is heated by a high-frequency welding machine, the tin wire is melted in the gap, the tube body 10 or the connector 20 can be rotated when the tin wire is melted, the tin wire is filled more fully, and the split processing procedure is completed after the tin wire and the whole structure are cooled. Of course, when the material of the filler 30 is selected, a meltable material with a proper melting point can be selected as the filler 30 to connect the pipe 10 and the connector 20 according to the material of the pipe 10 and the connector 20.

In another example, as shown in fig. 3, a plurality of recesses 12 are provided at the position of the pipe body 10 coinciding with the connector 20, so that the tin wire can be melted into the recesses 12 to increase the contact area, and a snap structure can be formed after solidification to increase the connection strength between the connector 20 and the pipe body 10.

Preferably, the external thread 21 on the connecting head 20 can increase the filling contact area of the tin wire, but cannot make direct contact with the tube 10, that is, in the case that the overlapped surface of the tube 10 and the connecting head 20 is smooth, the connecting head 20 and the tin wire can be pulled out from the opening 11. As shown in fig. 3, a concave portion 12 is provided as a guide groove on the surface of the pipe body 10 where the opening 11 and the external thread 21 coincide, and a convex portion 22 is provided on the connection head 20 to match with the concave portion 12, wherein the height of the protrusion of the convex portion 22 is greater than the distance from the external thread 21 to the surface of the pipe body 10, but in order to facilitate the sliding of the convex portion 22 into the concave portion 12, the concave portion 12 extends inward from the opening 11, so that the convex portion 22 can slide into the concave portion 12 from the opening 11 until the convex portion 22 contacts with the bottom of the groove.

Preferably, as shown in fig. 4, the concave portion 12 is a cross-shaped groove, the convex portion 22 can move in the concave portion 12, and a transverse groove of the cross-shaped groove can play a role in positioning, so that the connector 20 cannot move in the longitudinal direction after extending into the tube 10, that is, the connector 20 can keep in position after the convex portion 22 slides into the transverse groove, the connector 20 does not need to be clamped by other jigs in the process of melting the tin wire, and the convex portion 22 can be further wrapped and limited after the tin wire is melted.

While the present application has been described by way of examples, those of ordinary skill in the art will appreciate that there are numerous variations and permutations of the present application that do not depart from the spirit of the present application and that the appended embodiments are intended to include such variations and permutations without departing from the present application.
