Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel pipes, in particular to a stainless steel pipe with a blocking cap. Background Art

[0002] Stainless steel pipes are tubular products made of stainless steel materials. They are widely used in various industries and fields and are highly favored due to their unique properties.

[0003] As in the prior art, the patent with the patent authorization announcement number CN220623042U discloses a heat-insulating and pressure-resistant stainless steel pipe, which relates to the technical field of stainless steel pipes. The present application includes a steel pipe unit, which includes an inner pipe and an outer pipe sleeved on the outer peripheral side of the inner pipe, and an insulation cavity is formed between the inner pipe and the outer pipe, and a support ring frame is installed in the insulation cavity. The inner peripheral side of the outer pipe and the outer peripheral side of the inner pipe are connected by a support ring frame, and the support ring frame is filled with an insulation board. The stainless steel pipe of the heat-insulating and pressure-resistant stainless steel pipe adopts a sandwich structure design, and the outer pipe and the inner pipe are used to form an insulation cavity. In order to ensure the overall structure and pressure resistance, the outer pipe and the inner pipe are connected by a support ring frame, and the insulation board is installed in the insulation cavity, so that the stainless steel pipe has an insulation structure built in, thereby greatly improving the insulation effect, and directly meeting the insulation requirements through the stainless steel pipe.

[0004] Although the stainless steel pipe in the above patent can meet the insulation requirements through the insulation board, the stainless steel pipe has certain defects; since the end of the stainless steel pipe is relatively fragile, once the pipe mouth of the stainless steel pipe is hit or scratched during transportation and installation, it is easy to be damaged, resulting in the performance of the stainless steel pipe being affected. Therefore, the end of the existing stainless steel pipe lacks protection and needs to be improved. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a stainless steel pipe with a plugging cap to solve the problems raised by the background technology and protect the end of the stainless steel pipe body.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a stainless steel pipe with a sealing cap, comprising a stainless steel pipe body, both ends of the stainless steel pipe body are provided with threads, both ends of the stainless steel pipe body are threadedly connected with a first threaded ring, the first threaded ring is rotatably connected to a second threaded ring on a side away from the stainless steel pipe body, and the second threaded ring is clamped with a sealing cap on a side away from the first threaded ring.

[0007] Furthermore, a plurality of elastic blocks are fixedly connected to a side of the second threaded ring away from the first threaded ring, and the elastic blocks match the blocking cap.

[0008] Furthermore, a plurality of equidistantly distributed elastic clamping blocks are also fixedly connected to a side of the first threaded ring away from the second threaded ring, and clamping rings are fixedly connected to both ends of the stainless steel pipe body, and the clamping rings match the elastic clamping blocks.

[0009] Furthermore, an extrusion ring is provided on the side of the clamping ring away from the first threaded ring, the extrusion ring is threadedly connected to the stainless steel pipe body, and a chamfer matching the elastic clamping block is provided on the side of the extrusion ring close to the clamping ring.

[0010] Furthermore, the outer walls of the extrusion ring, the first threaded ring and the second threaded ring are all fixedly connected with a plurality of shifting blocks with similar structures, and the shifting blocks are equidistantly distributed.

[0011] Furthermore, a limiting groove is provided on a side of the first threaded ring close to the second threaded ring, and a limiting ring is fixedly connected to a side of the second threaded ring close to the first threaded ring, and the limiting ring matches the limiting groove.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] This stainless steel pipe with a sealing cap protects both ends of the stainless steel pipe body through the first threaded ring, the second threaded ring and the sealing cap to prevent impurities from entering the interior of the stainless steel pipe body. At the same time, the first threaded ring and the second threaded ring can be threadedly connected to the end of the stainless steel pipe body.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figure 1-4 A stainless steel pipe with a blocking cap comprises a stainless steel pipe body 1, both ends of the stainless steel pipe body 1 are provided with threads, both ends of the stainless steel pipe body 1 are threadedly connected with a first threaded ring 4, the first threaded ring 4 is rotatably connected with a second threaded ring 5 on the side away from the stainless steel pipe body 1, and the second threaded ring 5 is clamped with a blocking cap 6 on the side away from the first threaded ring 4.

[0021] The stainless steel pipe with a sealing cap in the utility model protects both ends of the stainless steel pipe body 1 through the first threaded ring 4, the second threaded ring 5 and the sealing cap 6 to prevent impurities from entering the interior of the stainless steel pipe body 1. At the same time, the first threaded ring 4 and the second threaded ring 5 can be threadedly connected to the end of the stainless steel pipe body 1. When the two stainless steel pipe bodies 1 are connected, it is only necessary to thread the second threaded ring 5 to the other stainless steel pipe body 1. The connection method is simple and easy to operate. In addition, the existing sealing structure (such as a sealing gasket, etc.) is used between the first threaded ring 4 and the second threaded ring 5, so no further elaboration is made here.

[0022] As shown in the figure and Figure 2 As shown, a plurality of elastic blocks 8 are fixedly connected to a side of the second threaded ring 5 away from the first threaded ring 4 , and the elastic blocks 8 match the blocking cap 6 .

[0023] Specifically, the blocking cap 6 is stuck between a plurality of elastic blocks 8. When the blocking cap 6 needs to be removed, the elastic blocks 8 are directly pushed outward, and then the blocking cap 6 can be removed. The removal method is simple and easy to operate.

[0024] like Figure 1 and Figure 2 As shown, a plurality of equally spaced elastic blocks 8 are also fixedly connected to one side of the first threaded ring 4 away from the second threaded ring 5 , and clamping rings 2 are fixedly connected to both ends of the stainless steel pipe body 1 , and the clamping rings 2 match the elastic blocks 8 .

[0025] Specifically, when the first threaded ring 4 is connected to the stainless steel pipe body 1, the first threaded ring 4 can be screwed until the elastic block 8 passes over the clamping ring 2, and the first threaded ring 4 is restricted by the clamping ring 2. This can prevent the first threaded ring 4 from rotating due to vibration and other reasons, causing the first threaded ring 4 to detach from the stainless steel pipe body 1 (similarly, when the second threaded ring 5 is threadedly connected to another stainless steel pipe body 1, it also needs to be screwed until the elastic block 8 passes over the clamping ring 2).

[0026] like Figure 1 and Figure 2 As shown, an extrusion ring 3 is provided on the side of the clamping ring 2 away from the first threaded ring 4 , the extrusion ring 3 is threadedly connected to the stainless steel pipe body 1 , and a chamfer matching the elastic block 8 is provided on the side of the extrusion ring 3 close to the clamping ring 2 .

[0027] Specifically, when the first threaded ring 4 is removed from the stainless steel pipe body 1, the extrusion ring 3 can be rotated to squeeze and lift the end of the elastic block 8 stuck on the clamping ring 2 through the extrusion ring 3, so that the clamping ring 2 loses its restricting effect, and then the first threaded ring 4 can be rotated normally to separate the first threaded ring 4 from the stainless steel pipe body 1 (similarly, the same method can be used to separate the second threaded ring 5 from another stainless steel pipe body 1).

[0028] like Figures 1 to 4 As shown, the outer walls of the extrusion ring 3, the first threaded ring 4 and the second threaded ring 5 are fixedly connected with a plurality of shifting blocks 7 with similar structures, and the shifting blocks 7 are evenly distributed. Rotating the extrusion ring 3, the first threaded ring 4 and the second threaded ring 5 by the shifting blocks 7 is more labor-saving and convenient.

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, a limiting groove 9 is formed on one side of the first threaded ring 4 close to the second threaded ring 5 , and a limiting ring 10 is fixedly connected to one side of the second threaded ring 5 close to the first threaded ring 4 , and the limiting ring 10 matches the limiting groove 9 .

[0030] Specifically, the second threaded ring 5 is restricted by the limiting groove 9 and the limiting ring 10. While ensuring that the second threaded ring 5 can rotate normally (the rotation does not drive the first threaded ring 4 to rotate together), it can also ensure that a large gap is not likely to appear between the first threaded ring 4 and the second threaded ring 5, thereby ensuring their sealing.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
