Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel pipes, in particular to a stainless steel pipe which is easy to assemble. Background Art

[0002] During the use of stainless steel pipes, in order to meet actual use needs, the stainless steel pipes need to be assembled.

[0003] Currently, when assembling two stainless steel pipes, it is mainly achieved by using a double-headed connecting pipe and bolts installed at both ends of the connecting pipe. When assembling two stainless steel pipes, the connecting ends of the two stainless steel pipes are first inserted into the connecting pipe, and then the bolts at both ends of the connecting pipe are tightened respectively, thereby achieving the connection and assembly between the two stainless steel pipes.

[0004] Although the existing double-head connecting pipe can realize the assembly between two stainless steel pipes, on the one hand, the direct insertion method will easily cause a gap to appear at the connection part of the two stainless steel pipes after connection, thereby making the sealing performance of the two adjacent stainless steel pipes after assembly poor. On the other hand, the connection and fixation between the two stainless steel pipes are achieved by screwing the bolts one by one, and the fixing process is relatively cumbersome, which makes the assembly efficiency between the two stainless steel pipes relatively low.

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] like Figure 1-Figure 3 As shown, in this embodiment, a stainless steel pipe that is easy to assemble includes a connecting pipe 1, an annular slot 2 is respectively opened at both ends of the connecting pipe 1, a stainless steel pipe body 3 is installed in each annular slot 2, and a quick lock assembly 4 is installed on the connecting pipe 1. The quick lock assembly 4 includes a conical surface pressure block 401, a conical surface screw sleeve 402, a cross swivel 403, a pressure rod 404, an arc-shaped pressure plate 405, a slide column 406, a sealing gasket 407 and a spring 408. There are two conical surface screw sleeves 402, and the two conical surface screw sleeves 402 are symmetrically distributed on both sides of the connecting pipe 1. The cross swivel 403 is located between the two conical surface screw sleeves 402, and four slide columns 406 are annularly installed on the side wall of the cross swivel 403 facing each conical surface screw sleeve 402. 1, four conical pressure blocks 401 are arranged in a ring shape in each annular slot 2. Each conical pressure block 401 is connected to a pressure rod 404 on the side wall facing the connecting pipe 1. The pressure rod 404 is located in the annular slot 2 and is connected to an arc-shaped pressure plate 405 at one end. A spring 408 is located between the conical pressure block 401 and the outer wall of the connecting pipe 1. When the cross screw sleeve rotates, it will use the sliding column 406 to realize the conical screw sleeve 402 to be screwed in along the surface of the connecting pipe 1. When the conical screw sleeve 402 is screwed in along the surface of the connecting pipe 1, the sliding column 406 will slide relative to the conical screw sleeve 402. After the conical pressure block 401 moves, it will press the arc-shaped pressure plate 405 on the outer wall of the stainless steel pipe body 3 under the action of the pressure rod 404, thereby realizing the compression and fixation of the stainless steel pipe body 3.

[0031] like Figure 1-Figure 3As shown, in this embodiment, the sliding column 406 is slidably matched with the conical sleeve 402, and a gap is reserved between the inner wall of the cross sleeve and the outer wall of the connecting tube 1. The reserved gap can ensure the convenient rotation of the cross sleeve relative to the connecting tube 1. The conical sleeve 402 has a conical annular cavity on the side facing the conical pressure block 401. The conical sleeve 402 is threadedly connected to the outer wall of the connecting tube 1. When the conical sleeve 402 moves, the conical pressure block 401 can be pressed with the help of the conical annular cavity. The pressure rod 404 passes through the outer wall of the connecting tube 1 and slides with the outer wall of the connecting tube 1. One end of the pressure rod 404 is connected to the arc pressure plate 405, and the other end of the pressure rod 404 is connected to the conical pressure block 401, which can ensure the synchronous sliding adjustment of the arc pressure plate 405 with the pressure rod 404.

[0032] like Figure 1-Figure 3 As shown, in this embodiment, the sealing gasket 407 is plugged into the annular slot 2, and the wall thickness of the stainless steel tube body 3 is smaller than the thickness of the annular slot 2. The sealing gasket 407 can further increase the sealing between the stainless steel tube body 3 and the connecting tube 1. Each annular slot 2 has four pressure rods 404 and four arc-shaped pressure plates 405. The arc-shaped pressure plates 405 are the main components for pressing and fixing the stainless steel tube body 3.

[0033] When the screw thread 402 is moved along the surface of the connecting tube 1, the conical surface pressing block 401 presses the pressure rod 404 downward, so that when the arc pressure plate 405 is pressed on the stainless steel tube body 3, the two stainless steel tube bodies 3 are quickly limited and assembled. In the above-mentioned assembly process, the stainless steel tube body 3 cooperates with the annular slot 2 and the sealing gasket 407 to effectively increase the sealing area of ​​the stainless steel tube body 3, thereby making the sealing area of ​​the two stainless steel tube bodies 3 larger after assembly and having better sealing performance. At the same time, in the above-mentioned connection process, only the cross swivel 403 needs to be rotated to achieve rapid compression of the stainless steel tube body 3, thereby making the assembly efficiency between the two stainless steel tube bodies 3 higher.

[0034] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
