Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment as required without making a contribution, but all the embodiments are protected by the patent law within the scope of the claims of the present invention.
The present embodiment relates to a copper pipe joint for facilitating welding, as shown in fig. 1 to 3, comprising: joint main body 100, accommodating portion 200, and positioning portion 300.
Wherein the joint body 100 is used for an external copper pipe to be inserted. The accommodating part 200 is disposed on the inner sidewall of the joint body 100, and the accommodating part 200 is recessed toward the outer sidewall of the joint body 100. The accommodating part 200 is used for accommodating the solder 400 and increasing the thickness of the welding part after welding. The positioning part 300 is protrudingly provided on an inner sidewall of the joint main body 100. The positioning part 300 is located at the side of the accommodating part 200 far away from the external copper pipe. The positioning part 300 serves to limit the depth of insertion of the external copper pipe into the joint main body 100.
Further, as shown in fig. 1-3, the receptacle 200 is generally annular. The outer side wall of the accommodating part 200 is correspondingly provided with an annular protrusion 210, correspondingly, the inner side wall of the accommodating part 200 is provided with an annular concave groove 201, and the solder 400 is preset in the annular concave groove 201. When the joint main body 100 is welded to the external copper pipe, the external copper pipe is welded to the joint main body 100 by the preset solder 400 in the annular concave groove 201 under the heated condition, and the annular concave groove 201 is filled, so that the thickness of the welding part between the joint main body 100 and the external copper pipe is increased.
Preferably, as shown in fig. 1-3, the joint body 100 is any one of a double-ended straight pipe joint, a double-ended elbow joint, a three-way joint, and a four-way joint. In this embodiment, the connector body 100 is a double-ended straight tube connector for insertion of two outer copper tubes.
Preferably, as shown in fig. 1 to 3, two accommodating portions 200 are symmetrically arranged, and each of the two accommodating portions 200 corresponds to an outer sidewall of the outer copper pipe.
Further, as shown in fig. 1 to 3, the positioning portion 300 is disposed at a central position between the two accommodating portions 200, so that the two external copper pipes are inserted into the joint main body 100 with the same depth, the stress uniformity of the welding point between the two external copper pipes and the joint main body 100 after welding is ensured, and the stability and the firmness of the welding point are improved.
Further, as shown in fig. 1 to 3, the positioning part 300 is a protruding ring 310 protruding from the inner sidewall of the joint main body 100. When external copper pipe inserted, the lateral wall of outside copper pipe and the inside wall of connecting main part 100 contacted each other, and when the tip of outside copper pipe and bulge loop 310 butt, can learn outside copper pipe and arrived the male degree of depth to the insertion of outside copper pipe has been made things convenient for.
It is noted that the inner sidewall of the joint body 100 is generally frustoconical, i.e., the radial dimension of the port is greater than the radial dimension at the raised ring 310. The joint main body 100 arranged in this way can be tightly connected with an external copper pipe after being inserted and connected, so that the position between the external copper pipe and the joint main body 100 is unchanged in the welding process, and welding is facilitated.
Further, as shown in fig. 1-3, the cross-sections of the convex ring 310, the annular concave groove 201 and the annular protrusion 210 are all circular-arc-shaped.
It should be noted that, since the cross section of the annular concave groove 201 is arc-shaped, the cross section of the solder 400 preset in the annular concave groove is also arc-shaped. Moreover, the contact surface between the preset solder 400 and the outer side wall of the outer copper pipe is a continuous circular ring surface, and the contact surface between the preset solder 400 and the joint main body 100 is a continuous arc surface, so that the solder 400 preset in the annular concave groove 201 is continuous with the connection surface between the outer copper pipes after being welded, and is continuous with the connection surface between the joint main body 100, and the thickness of the connection part is greater than the wall thickness of the joint main body 100, thereby ensuring the welding stability between the outer copper pipe and the joint main body 100.
The working principle of the present embodiment is roughly as follows: in the welding, the outer copper pipe is inserted into the joint main body 100, and the insertion is stopped when the end of the outer copper pipe abuts against the positioning portion 300 in the joint main body 100. Then, aligning the gun head of the electromagnetic heating gun with the position of the annular protrusion 210, and then starting the electromagnetic heating gun, so that the electromagnetic heating gun heats the annular protrusion 210, the preset solder 400 and the external copper pipe until the preset solder 400 connects the external copper pipe with the joint main body 100, and then stopping heating until cooling. The copper pipe joint is provided with the accommodating part 200 for storing the solder 400 in advance, so that the problem that the solder 400 is carried in a welding process is avoided, and the welding process is simplified; meanwhile, when the external copper pipe is inserted into the joint main body 100, the depth of the external copper pipe inserted into the copper pipe is consistent through the positioning action of the positioning part 300 arranged on the inner side wall, so that the condition that the stress of a welding part is uneven due to different insertion depths of the external copper pipe is avoided, and the welding process is further simplified as long as the external copper pipe is inserted to abut against the positioning part 300 during welding; in addition, holding portion 200 sets up annular depressed groove 201 on the inside wall, set up annular sand grip on the outside wall for outside copper pipe when with joint main part 100 welding, preset solder 400 and can fill annular depressed groove 201, and then guarantee the thickness of weld part between outside copper pipe and the joint main part 100, further guarantee the outside copper pipe after the welding and connect the steadiness between the main part 100, it is simple to have welding process, the welding position is accurate, the welding point is stable, firm, long service life's advantage after the welding.
The above description is only for the purpose of illustration and not limitation, and other modifications or equivalent replacements made by those skilled in the art to the technical solution of the present invention should be covered by the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
