Technical Field

[0001] The utility model relates to the field of butt-welding flanges, in particular to an anti-slip butt-welding flange. Background Art

[0002] Patent No. CN219102304U discloses a butt-welding flange. The utility model has a reasonable structural design. The device sleeves an external pipe on it through an annular groove and welds it. The threaded movement of the sleeve is coordinated to wrap the external pipe and weld it, so that the butt-welding flange is wrapped and fixed on the external pipe. It is easy to install and ensures the fixation and support strength of the welding part after the butt-welding flange is welded.

[0003] However, since there is no supporting structure in the above-mentioned existing butt-welded flange, the stability is low when welding the external pipe.

[0004] In order to solve the above problems, the utility model provides an anti-slip butt-welding flange. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides an anti-slip butt-welding flange to solve the technical problem in the prior art that "since there is no supporting structure in the device, the stability is low when welding the external pipe".

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a non-slip butt-welding flange, comprising a first base, a first butt-welding flange body is fixedly connected to the right side of the first base, a first convex pattern is fixedly connected to the surface of the first butt-welding flange body, a connecting ring is threadedly connected to the surface of the first convex pattern, a second convex pattern is threadedly connected in the connecting ring, a second butt-welding flange body is fixedly connected in the second convex pattern, one end of the second butt-welding flange body is fixedly connected to the second base, through holes are symmetrically opened on both sides of the right side of the second base, and a fixing rod is fixedly connected to the right side of the first base.

[0007] As a preferred technical solution of the utility model, a concave pattern is provided in the connection ring, and the concave pattern is threadedly connected to the first convex pattern and the second convex pattern.

[0008] As a preferred technical solution of the utility model, a first anti-slip pattern is fixedly connected to the surface of the connecting ring.

[0009] As a preferred technical solution of the utility model, the right end of the fixing rod is fixedly connected with a threaded rod, and the surface of the threaded rod is threadedly connected with a nut.

[0011] As a preferred technical solution of the present utility model, a second anti-slip pattern is fixedly connected to the surface of the nut, and the left side of the knob abuts against the right side of the second base.

[0012] The utility model provides an anti-slip butt welding flange, which has the following beneficial effects:

[0013] 1. Leave a distance between the first body and the second body to sleeve the external pipe and weld it. After completion, control the nut to rotate counterclockwise on the surface of the threaded rod to make the pipes fit more closely. At this time, the first body and the second body are not fitted together, leaving a gap for annular welding of the external pipes. During welding, the positioning and the action of the first base and the second base make the welding smoother.

[0014] 2. The connection ring can be used to protect the first body and the second body, and the sealing gasket can improve the sealing effect and provide anti-slip properties, so that the first body and the second body can be firmly attached to the external pipe. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0020] refer to Figure 1-3The utility model provides a technical solution: a non-slip butt-welding flange, comprising a first base 1, a first butt-welding flange body 2 is fixedly connected to the right side of the first base 1, a first convex pattern 3 is fixedly connected to the surface of the first butt-welding flange body 2, a connecting ring 12 is threadedly connected to the surface of the first convex pattern 3, by setting the connecting ring 12, when the first body and the second body complete the annular welding, they can be rotated on their surfaces through the connecting ring 12, thereby improving the stability of the welding point and improving the aesthetics, a second convex pattern 11 is threadedly connected in the connecting ring 12, a second butt-welding flange body 10 is fixedly connected in the second convex pattern 11, one end of the second butt-welding flange body 10 is fixedly connected to the second base 8, through holes 9 are symmetrically opened on both sides of the right side of the second base 8, a fixing rod 5 is fixedly connected to the right side of the first base 1, and by setting the through hole 9 and the fixing rod 5, the fixing rod 5 can push the threaded rod 6 into it through the position in the through hole 9.

[0021] The connection ring 12 is provided with a concave groove 14 , and the concave groove 14 is threadedly connected to the first convex groove 3 and the second convex groove 11 .

[0022] The surface of the connecting ring 12 is fixedly connected with a first anti-slip pattern 13 .

[0023] Among them, the right end of the fixing rod 5 is fixedly connected with a threaded rod 6, and the surface of the threaded rod 6 is threadedly connected with a nut 7. By setting the nut 7, when the first body and the second body are fitted together, the nut 7 rotates on the surface of the threaded rod 6, so that the fit between the first body and the second body is higher, and at the same time, the welding between the first body and the second body is more stable.

[0024] The surface of the nut 7 is fixedly connected with a second anti-slip pattern, and the left side of the knob abuts against the right side of the second base 8 .

[0025] Among them, the first butt-welding flange body 2 and the second butt-welding flange body 10 are both fixedly connected with a sealing gasket 4, and the surfaces of the first butt-welding flange body 2 and the second butt-welding flange body 10 are coated with an anti-corrosion layer 15. By setting the sealing gasket 4 anti-corrosion layer 15, the sealing gasket 4 can improve the sealing between the first body and the second body and the pipeline, and also has a certain protective performance. At the same time, under the action of the anti-corrosion layer 15, the service life of the first body and the second body is increased.

[0026] The working principle of the utility model is as follows: the first body and the second body are directly sleeved on the pipeline, and the threaded rod 6 is inserted into the connecting hole. At the same time, the nut 7 is rotated counterclockwise on the threaded rod 6 so that the left side of the nut 7 completely abuts against the right side of the second base 8, so that the first body and the second body are fitted together. When the first body and the second body are annularly welded, the fit is more stable. At the same time, under the action of the protective pad, the inner wall of the pipeline is fitted and the inside of the pipeline is protected, so that the impact force is slowly released when it is impacted by the outside world. The anti-corrosion layer 15 is used for anti-corrosion, thereby increasing the service life of the first body and the second body.

[0027] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and utility model concept of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
