Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of filters, in particular to a conductive tube. Background Art
[0002] The trap and the filter have a conductive tube with a guide pin formed in the center of the conductive tube for grounding. In the past, the conductive tube and the guide pin were integrally formed by turning and milling from a blank. Since the conductive tube has a hollow structure inside, there is only one guide pin in the middle, and one end of the guide pin extends to the outside of the conductive tube. The specifications of the blank need to meet the processing of the workpiece. Most of the material will be milled away during the processing, resulting in material waste and high cost. Utility Model Content
[0003] The utility model aims to provide a conductive tube to solve the problems mentioned in the background technology.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0005] A conductive tube comprises a split-structure tube body and a guide pin; the tube body is a stretched stamping part; the tube body comprises a tube bottom and a tube wall connected to the tube bottom; a mounting hole is provided at the center of the tube bottom; the lower end of the guide pin is fixed at the mounting hole position by riveting and spot welding.
[0006] Further description of the utility model: a recessed portion sunken into the tube body is provided at the center of the tube bottom; the mounting hole is formed at the center of the recessed portion; the recessed portion is filled with a stone mud layer; and the stone mud layer covers the lower end of the guide pin.
[0007] Further description of the utility model: the bottom of the stone mud layer is plated with a tin solder layer; the tin solder layer does not protrude from the bottom of the tube.
[0008] Further description of the utility model: the tube body and the guide needle are both made of stainless iron material; the outer surfaces of the tube body and the guide needle are plated with a copper layer.
[0009] Further description of the utility model: the lower outer wall of the guide needle is provided with a limiting convex ring; the limiting convex ring touches the top of the tube bottom.
[0010] The beneficial effects of the utility model are:
[0011] This design forms the tube body and the guide needle separately. The tube body is a stretched stamping part with stable and efficient processing. A mounting hole is provided on the tube body for installing the guide needle. The guide needle is first riveted to the mounting hole and then spot welded for reinforcement, so that the guide needle is fixed in the middle of the tube body. This connection method is stable and can greatly save production costs. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 It is the overall structure diagram of the utility model;
[0013] Figure 2 It is a structural diagram of the pipe body of the utility model. DETAILED DESCRIPTION
[0014] The utility model is further described below in conjunction with the accompanying drawings:
[0015] like Figure 1-2 As shown, a conductive tube comprises a split structure tube body 1 and a guide pin 2; the tube body 1 is a stretched stamping part; the tube body 1 is a cylindrical structure, comprising a tube bottom 11 and a tube wall 12 connected to the tube bottom 11; a mounting hole 111 is provided at the center of the tube bottom 11; the lower end of the guide pin 2 is fixed at the position of the mounting hole 111 by riveting and spot welding; the tube body 1 and the guide pin 2 are formed separately, the tube body 1 is a stretched stamping part, which is formed by stretching and stamping with a stamping die, and the guide pin 2 can be formed by cold heading stamping, and the mounting hole 111 is provided on the tube body 1 for installing the guide pin 2, and the guide pin 2 is first fixed on the mounting hole 111 by riveting and then spot welding is performed to reinforce it, so that the guide pin 2 is fixed at the middle position of the tube body 1.
[0016] A recess 112 sunken into the tube body 1 is provided at the center of the tube bottom 11; the mounting hole 111 is formed at the center of the recess 112; the recess 112 is filled with a stone mud layer 101; the stone mud layer 101 covers the lower end of the guide pin 2, and since the guide pin 2 is riveted on the tube bottom 11, the guide pin 2 needs to pass through the mounting hole 111; through the design of the recess 112, the lower end of the guide pin 2 does not protrude from the tube bottom 11 after riveting, and is then filled with the stone mud layer 101, which has a further stabilizing effect and prevents the lower end of the guide pin 2 from leaking, thereby improving the aesthetic effect.
[0017] The bottom of the stone mud layer 101 is plated with a solder layer 102; the solder layer 102 does not protrude from the tube bottom 11, the solder layer covers the stone mud layer 101, and the solder layer does not protrude from the tube bottom 11 to avoid affecting its use effect. In this design, the solder layer is flush with the bottom surface of the tube bottom 11.
[0018] The tube body 1 and the guide needle 2 are both made of stainless iron; the outer surfaces of the tube body 1 and the guide needle 2 are plated with a copper layer, and the plating material can be replaced according to usage requirements. This design uses stainless iron as the main body material to reduce costs.
[0019] A limiting convex ring 21 is provided on the lower outer wall of the guide pin 2; the limiting convex ring 21 contacts the top of the tube bottom 11, and the lower end of the guide pin 2 passes through the mounting hole 111, and the limiting convex ring 21 contacts the top of the tube bottom 11 for limiting the position, and then the lower end of the guide pin 2 is riveted and fixed to the bottom of the mounting hole 111, and then spot welding is performed for reinforcement after the riveting is completed.
[0020] The above description does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
