Preferably, the joint of the clamping part and the end cover main body is provided with an embedding groove.
Preferably, the cylindrical head welding nail and the end cover main body are fixedly connected with each other, and the cylindrical head welding nail and the end cover main body are welded in a stud welding mode.
Preferably, the fusing head is inserted into one end of the placing groove and then forms a fusing part and a fusing layer through stud welding, the fusing part is located on the outer surface of the joint of the fusing head and the end cover main body, and the fusing layer is located in the inner cavity of the fusing head and the material sucking ring layer.
Preferably, the cylinder head welding nail is made of a copper material.
The utility model discloses beneficial effect who has:
1. the inside bottom plate that is provided with of standing groove, protruding type fixture block has been seted up at the top of bottom plate, when the cylinder head welding nail plug-in advances protruding type fixture block inside, the junction forms the connector of a echelonment, when the mode through stud welding is welded to both, the fusing head after melting can be filled in echelonment department, make the connection effect between the two better, fusing head is through stud welding back simultaneously, the welding flux that its produced is synchronous to being filled the inside on inhaling the material circle layer, increase the stability of being connected between cylinder head welding nail and the end cover main part, can avoid the welding flux to enter into the inner wall department of end cover main part simultaneously again.
2. The top of end cover main part is the plane of horizontality to make the fuse-link on cylinder head welding nail surface and the mutual overlap joint of end cover main part more steady, when making it carry out stud welding, the welding effect is better.

FIG. 2 is a schematic sectional view of an assembly of the present invention;
fig. 3 is an enlarged schematic view of a structure shown at a in fig. 2.
In the figure: 1. an end cap body; 11. a clamping part; 12. embedding a groove; 2. a placement groove; 21. a material sucking ring layer; 3. cylindrical head welding nails; 31. an interface; 4. fusing the head; 41. a fusing portion; 42. and fusing the layers.
Detailed Description
The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.
Example (b): the connecting structure of the liquid accumulator end cover comprises an end cover main body 1, wherein a clamping portion 11 is arranged at the bottom of the end cover main body 1, the thickness of the outer ring of the end cover main body 1 is larger than that of the integral side wall, an inward embedding groove 12 is formed at the joint of the end cover main body 1 and the clamping portion 11, and the embedding groove 12 is arranged in a circular ring shape around the outer ring of the end cover main body 1.
The middle part of the end cover main body 1 is provided with a placing groove 2, the top of the end cover main body 1 is provided with a cylindrical head welding nail 3, the cylindrical head welding nail 3 is made of a copper material, the cylindrical head welding nail 3 and the end cover main body 1 are fixedly connected with each other, the cylindrical head welding nail 3 and the end cover main body 1 adopt a welding mode of stud welding, the bottom of the cylindrical head welding nail 3 is provided with a socket 31, a fusion head 4 is fixedly sleeved on the surface of the cylindrical head welding nail 3, a material sucking ring layer 21 is arranged on the surface of the cylindrical head welding nail 3 in a surrounding mode, the material sucking ring layer 21 is positioned below the fusion head 4, the fusion head 4 is spliced into one end of the placing groove 2 and then forms a fusion part 41 and a fusion layer 42 through stud welding, the fusion part 41 is positioned on the outer surface of the connection part of the fusion head 4 and the end cover main body 1, and the fusion layer 42 is positioned in.
The principle of the utility model is as follows: at this moment, the cylinder head welding nail 3 is placed inside the placing groove 2 at the top of the end cover, the fusing head 3 positioned at the bottom of the cylinder head welding nail 3 is in lap joint with the top of the end cover main body 1 at the moment, after the effect of stable placement is played for the cylinder head welding nail 3, then, stud welding is placed on the cylinder head welding nail 3 to be welded, the fusing head 4 is instantly melted under high temperature, the melted partial fusing head 4 material slowly melts into the placing groove 2, then, the material gradually melts into the gap through the gap between the cylinder head welding nail 3 and the placing groove 2 to form, when the material is excessively melted, the redundant material can be adsorbed by the material absorbing ring layer 21 to form the fusing layer 42, the stability of integral connection is improved, and therefore the cylinder head welding nail 3 is fixed at the top of the end cover main body 1.
