As used in the specification and appended claims of the present application, the singular expressions "one", "a kind of", "above", "the" and "this" are intended to also include plural expressions, unless there is a clear indication to the contrary in the context. It should also be understood that the term "and / or" used in the present application refers to and includes any or all possible combinations of one or more listed items.
[0030] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.
[0031] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.
[0032] See also Figure 1, is a shell device for accommodating nitrogen and a heating rod for welding disclosed in an embodiment of the present application, including a first shell 10, a heating rod 20 and a welding head 30.
[0033] The first shell 10 is cylindrical in shape, and is provided with an air inlet 11 on the side thereof for supplying nitrogen from an external nitrogen source, which may of course be other inert nitrogen. Figure 2 A first through hole 12 is disposed at one end of the first shell 10 for the welding head 30 to penetrate, and a gas outlet 13 is disposed around the first through hole 12 for nitrogen output.
[0034] See also Figure 1 The heating rod 20 is located in the first shell 10, and one end of the heating rod 20 is in contact with the welding head 30, wherein nitrogen is filled in the accommodation space 21 between the heating rod 20 and the inner side of the first shell 10. One end of the welding head 30 is located in the shell and is in contact with and fixed to the heating rod 20, and the other end is a welding end (tip) exposed from the first through hole 12.
[0035] In this way, the external nitrogen source enters the first shell 10 through the air inlet 11, and after being heated by the heating rod 20, it is uniformly output from the air outlet 13 to provide a stable protective atmosphere for the welding area. The welding head 30 is fixed to the heating rod 20 by abutting, so as to achieve precise heating of the welding area. In this way, nitrogen and preheating can be effectively combined, making the operation in the welding process more convenient, improving welding efficiency and reducing investment costs.
[0036] Specifically, an extension tube 14 is provided at the air inlet 11 to facilitate the user to connect an external nitrogen source, thereby improving the convenience and applicability of the device. The air outlet 13 is evenly distributed on the first shell 10 around the first through hole 12, so that the nitrogen can be more evenly covered in the welding area to further improve the welding quality and protection effect. The welding head 30 and the heating rod 20 are detachably connected, which can facilitate the user to maintain and replace parts of the shell device, reducing the use cost and maintenance difficulty.
[0037] See also Figure 1 and Figure 2 The housing device further includes: a second housing 40, one end of which is sleeved on the first housing 10, and the other end of which is configured to be conical and provided with a welding hole 41 for the end of the welding head 30 away from the heating rod 20 to pass through.
[0038] The nitrogen is outputted from the gas outlet 13 and the welding hole 41 in sequence, and combined with the conical setting of the second shell 40, when the nitrogen passes through the welding hole 41, a more concentrated protective gas flow is formed on the welding head 30, thereby effectively preventing oxidation and contamination during the welding process. Figure 2 as shown in .
[0039] See also Figure 3 A plurality of slots 42 are provided on the circumferential side of the second shell 40 on which the first shell 10 is sleeved. The slot 42 structure can be as follows: Figure 2 As shown in , this makes it easy to sleeve the second shell 40 on the first shell 10, thereby facilitating the assembly of the shell device.
[0040] See also Figure 1 and Figure 3 In order to facilitate the end of the heating rod 20 away from the welding head 30 to be connected to an external power source to ensure the heating of the heating rod 20, in the present embodiment, one end of the heating rod 20 is exposed to the first shell 10.
[0041] Furthermore, in order to prevent nitrogen from escaping from the end of the first shell 10 away from the welding head 30 due to the heating rod 20 being exposed, the present embodiment further includes a sleeve 50 , and a second through hole 51 is correspondingly provided on the sleeve 50 for exposing the heating rod 20 .
[0042] The outer peripheral side of the sleeve 50 is also arranged to abut against the inner side of the first shell 10. Thus, the second through hole 51 is arranged to facilitate the insertion of the heating rod 20, and ensure the close fit between the heating rod 20 and the sleeve 50, effectively preventing nitrogen from escaping from the other end of the first shell 10 away from the air outlet 13, thereby improving the sealing performance of the device.
[0043] Here, it is worth mentioning that the sleeve 50 can further enhance the stability between the heating rod 20 and the first shell 10, prevent the heating rod 20 from shaking during the welding process, and thus improve the welding quality.
[0044] See also Figure 3 and Figure 4 In order to strengthen the abutment stability between the heating rod 20 and the welding head 30 , in this embodiment, a first fixing member 60 and a second fixing member 70 are further included.
[0045] The first fixing member 60 has one end which is sleeved on the heating rod 20 and is located in the first housing 10, and a limiting groove 61 is provided at one end of the first fixing member 60 (see Figure 4 ), for one end of the welding head 30 to be accommodated in the limiting groove 61 and abut against the heating rod 20, wherein one end of the welding head 30 is arranged relative to the shape of the limiting groove 61. In this way, the welding head 30 and the heating rod 20 can be accurately aligned and limited to avoid the welding head 30 from rotating during the welding process, thereby further improving the welding effect.
[0046] The second fixing member 70 can be screwed onto the welding head 30 and the first fixing member 60 and is located in the first housing 10, and the second fixing member 70 is screwed onto the first fixing member 60. Thus, by setting the first fixing member 60 and the second fixing member 70 to cooperate and fix the heating rod 20 and the welding head 30, a stable connection between the welding head 30 and the heating rod 20 can be achieved. In addition, it is also convenient to disassemble and replace the welding head 30.
[0047] Specifically, an adjustment hole 62 is provided on the first fixing member 60. In the present embodiment, the shell device further includes a fixed adjustment member for penetrating the adjustment hole 62 and abutting against the heating rod 20. Such a fixed adjustment member can facilitate the installation of the first fixing member 60 and the heating rod 20 to be more flexible and adjustable, so as to cooperate with the second fixing member 70, so as to achieve a fixed connection between the welding head 30 and the heating rod 20.
[0048] In summary, the embodiment of the present application discloses a shell device for accommodating nitrogen and a heating rod for welding. By setting the nitrogen to enter the first shell 10 through the air inlet 11, and after being heated by the heating rod 20, it is uniformly output from the air outlet 13, which can provide a stable protective atmosphere for the welding area. The welding head 30 is fixed to the heating rod 20 by abutting, and can achieve precise heating of the welding area. In this way, nitrogen and preheating can be effectively combined, making the operation in the welding process simpler, and improving the welding efficiency and reducing the investment cost.
