Description

Technical Field

[0001] The utility model relates to the technical field of steel pipes, in particular to a pre-fixed cold-drawn precision welded steel pipe. Background Art

[0002] As we all know, pre-fixed cold-drawn precision welded steel pipe is a welded steel pipe that has been processed by cold drawing. It is usually used in application scenarios that require high precision and excellent mechanical properties. The steel pipe is welded by welding steel strips or other forms of steel through a welding process, and then cold-drawn to give it better dimensional accuracy, surface finish and mechanical properties.

[0003] The existing pre-fixed cold-drawn precision welded steel pipes are inconvenient. After long-term use, the outer wall of the steel pipe body will be covered with dust. If the dust is not cleaned in time, the dust will cover the surface of the steel pipe. If cracks appear on the surface of the steel pipe, the staff cannot find them in the first time, which may easily cause safety hazards. However, when the existing steel pipes are cleaned, the staff usually have to look for suitable tools in the surrounding environment or bring their own cleaning tools, which is very troublesome and will waste a lot of time, thereby reducing work efficiency. The tools found in the surrounding environment are also prone to incomplete cleaning. Utility Model Content

[0004] (1) Technical problems solved

[0005] In view of the deficiencies in the prior art, the utility model provides a pre-fixed cold-drawn precision welded steel pipe.

[0006] (2) Technical solution

[0007] The cam is connected with the sliding member by the sliding connection of the sliding member, and the sliding member is connected with the sliding member by the sliding connection of the sliding member.

[0008] In order to improve the stability, the present invention has the following improvements: the two docking points are symmetrically arranged, and the two limiting mechanisms are symmetrically arranged.

[0009] In order to achieve the anti-slip effect, the present invention is improved in that the outer wall of the scraper ring is provided with an anti-slip layer, and the anti-slip layer is fixedly connected to the outer wall of the scraper ring.

[0010] In order to facilitate the sliding of the scraper ring on the body, the utility model is improved in that the scraper ring is matched with the body.

[0011] (3) Beneficial effects

[0012] Compared with the prior art, the present invention provides a pre-fixed cold-drawn precision welded steel pipe, which has the following beneficial effects:

[0013] The pre-fixed cold-drawn precision welded steel pipe has a structure in which a scraper ring is arranged on the main body to clean the dust on the outer wall of the main body, so as to avoid the situation in which the dust covers the cracks on the main body when the staff inspects the outer wall of the main body, resulting in the staff being unable to discover the cracks in time, thereby avoiding safety hazards in the main body. When the scraper ring is used for a long time and is damaged and needs to be replaced, the control limit mechanism no longer limits the scraper ring, and then the scraper ring can be separated from the equipment and replaced with a new scraper ring.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4, a pre-fixed cold-drawn precision welded steel pipe, comprising a body 1, a docking point 2, a scraper ring 3 and a limiting mechanism 4, the docking point 2 is arranged on the body 1, the scraper ring 3 is sleeved on the body 1, the body 1 and the scraper ring 3 are slidingly arranged, the limiting mechanism 4 comprises a slot 5, a movable block 6, a long block 7, a telescopic rod 8, a bearing 9, a damping block 10, a slide groove 11 and a slider 12, the slot 5 is opened on the docking point 2, one end of the movable block 6 is hinged to the inner wall of the slot 5, one end of the long block 7 extends into the slot 5, the other end of the long block 7 abuts against the bottom of the long block 7, one end of the telescopic rod 8 is connected to the top of the long block 7, the telescopic rod 8 The other end is connected to the damping block 10 through the bearing 9, and the damping block 10 partially extends into the inner wall of the slot 5. The slide 11 is provided on the damping block 10, and one end of the slider 12 is slidably connected to the slide 11, and the other end of the slider 12 partially extends into the inner wall of the slot 5. There are two docking points 2, and the limiting mechanism 4 is provided with two groups. In this embodiment, the body 1 can be installed to a suitable position through the docking point 2. The body 1 is a conventional pre-fixed cold-drawn precision welded steel pipe on the market. It is not described in detail here. When the body 1 is used for a long time, it is necessary to inspect the body 1, but when the outer wall of the body 1 is covered with dust, the staff first pushes the scraper ring back and forth 3. Slide the scraper ring 3 on the body 1 to clean the dust on the outer wall of the body 1, avoiding the staff from checking whether there are cracks on the outer wall of the body 1. When the scraper ring 3 is used for a long time and is damaged and needs to be replaced, first separate the body 1 from the external equipment, and then push the slider 12 on the slide 11 to separate the slider 12 from the slide 11. The slider 12 has a damping effect and needs to be pushed hard. Then pull the damping block 10 upward to extend the telescopic rod 8 so that the part of the damping block 10 extending into the slot 5 is separated from the slot 5. Then rotate the damping block 10 on the bearing 9 to rotate the damping block 10 ninety degrees. Then the staff holds the damping block 10 with their hands and pushes the damping block 10. Move the long block 7 in the slot 5, retract the long block 7 to the inner wall of the slot 5, separate the long block 7 from the bottom of the movable block 6, and after the long block 7 is retracted to the maximum distance from the inner wall of the slot 5, rotate the movable block 6 to retract the movable block 6 into the slot 5. After the long block 7 is retracted to the maximum distance from the inner wall of the slot 5, the movable block 6 can completely enter the slot 5, and then push the scraper ring 3 to separate the scraper ring 3 from the body 1, and then separate it at the docking point 2, you can separate the scraper ring 3 from the body 1, and then replace it with a new scraper ring 3. The new scraper ring 3 can be bought from the manufacturer and will not be described in detail here. The size and shape of all components in this structure are not specifically limited here and need to be produced according to actual conditions.

[0021] In order to improve stability, in this embodiment, the two docking portions 2 are symmetrically arranged, and the two limiting mechanisms 4 are symmetrically arranged.

[0022] The anti-slip effect of the outer wall of the scraper ring 3 is poor. When the staff's hands come into contact with the scraper ring 3 again, it is easy to slip. In order to solve this problem, in this embodiment, the outer wall of the scraper ring 3 is provided with an anti-slip layer, and the anti-slip layer is fixedly connected to the outer wall of the scraper ring 3.

[0023] In order to facilitate the sliding of the scraper ring 3 on the body 1 , in this embodiment, the scraper ring 3 is matched with the body 1 .

[0024] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
