[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-3 , the present utility model provides a welding protection gas inflation device for non-standard metal pipe fittings, including a supporting part 100, on which a through hole 101 is opened; specifically, the shape of the supporting part 100 is not limited, and it can be an octagonal structure as shown in Figure 1 or a circular structure;

[0025] an inflation pipe 200, which is arranged through the through hole 101; specifically, when the inflation pipe 200 is in use, one end is connected to the gas supply end, and the other end extends into the non-standard pipeline;

[0026] The clamping part 300 is movably arranged on the supporting part 100. There are two clamping parts 300, which are distributed on both sides of the inflatable tube 200. Specifically, when in use, the clamping part 300 is used to clamp the end of the non-standard pipe to fix the inflatable tube 200 without falling off.

[0027] The adjusting part 400 is used to connect the two clamping parts 300. By means of the adjusting part 400, the two clamping parts 300 can be moved closer to or away from each other to adjust the distance. Specifically, through the adjusting part 400, the distance between the two clamping parts 300 can be adjusted according to the pipe diameter of the non-standard pipe, so as to achieve better adaptation and fixation.

[0028] The utility model is more suitable for the inflation work of non-standard pipes, and can more flexibly adapt to the inner diameter of the pipes, so that the inflation device can be firmly fixed on the pipe to be welded, avoiding the problems of easy falling off, which affects the welding quality and causes safety accidents. Moreover, this inflation device is small and convenient to carry.

[0029] In an embodiment, the adjusting part 400 includes an internal gear 401 arranged on the supporting part 100. The internal gear 401 is respectively meshed with two racks 402 that are movably arranged on the supporting part 100 and move in opposite directions. The two racks 402 are respectively connected with the two clamping parts 300.

[0030] Specifically, when it is necessary to adjust the clamping part 300 according to the pipe diameter of the non-standard pipe, by moving one-sided rack 402, the other-sided rack 402 can be driven to move through the transmission of the internal gear 401, and then the two clamping parts 300 can be driven to move closer to or away from each other, so as to better adapt to the non-standard pipe.

[0031] In an embodiment, the adjusting part 400 further includes an elastic part 403. The two ends of the elastic part 403 are respectively connected with the two clamping parts 300.

[0032] Specifically, through the elastic part 403, the mutual acting force between the two clamping parts 300 can be maintained. When this inflation device is in use, after the clamping part 300 is connected with the non-standard pipe, a stable clamping force can be provided, avoiding the problem of the falling off of this inflation device, which not only improves the welding quality but also improves the safety.

[0033] In an embodiment, a guide groove 102 is formed on the supporting part 100, and the rack 402 is limited to move linearly in the guide groove 102. With such a setting in this embodiment, the movement of the rack 402 can be limited, so that the rack 402 keeps linear movement when moving, so as to achieve the purpose of driving the two clamping parts 300 to move away from or close to each other by moving one-sided rack 402.

[0034] In one embodiment, the elastic member 403 is a spring or a pull rope. Specifically, the spring or the pull rope can provide a stable clamping force after the clamping portion 300 is connected to the non-standard pipeline. The elastic member 403 is not limited to a spring or a pull rope, and any other structure that can provide an elastic force is acceptable.

[0035] In one embodiment, the clamping surface of the clamping portion 300 is in a concave arc shape. With this setting in this embodiment, the shape of the clamping portion 300 is more in line with the outer shape of the non-standard pipeline, thereby achieving a better clamping effect and maintaining stability.

[0036] In one embodiment, the clamping portion 300 has a contact portion connected to the elastic member 403. With this setting in this embodiment, the setting of the contact portion can provide a stable contact point for the contact between the elastic member 403 and the clamping portion 300, and further enables the clamping portion 300 to provide a stable clamping force during use.

[0037] In one embodiment, the contact portion is a round hole or a convex block with a card slot. Specifically, the round hole can be applied to the connection of the spring, and the convex block with a card slot can be applied to the connection of the pull rope, with better adaptability.

[0038] It should be noted that if there are directional indications such as up, down, left, right, front, back... in the embodiments of the present invention, then the directional indications are only used to explain the relative position relationship, movement conditions, etc. between components in a specific posture as shown in the drawings. If the specific posture changes, the directional indications will also change accordingly.

[0039] In addition, if there are descriptions such as "first", "second", etc. in the embodiments of the present invention, then the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features.
