[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1: Please see Figure 1-4 The present invention provides the following technical solution: a sonic logging pipe connection structure, including a first pipe 1, a second pipe 4 provided on one side of the first pipe 1, a sealing component 3 provided at one end of the first pipe 1 and the second pipe 4, and the first pipe 1 and the second pipe 4 connected by a connecting component 2. The connecting component 2 includes a folding plate 22. The folding plate 22 is fixed to one side of both ends of the first pipe 1. The annular plate 21 is fixed to one side of the surface of the second pipe 4. The annular plate 21 has slots 23 on both sides corresponding to the folding plate 22. A sliding groove 24 is provided on one side of the slot 23. A pull ring 26 is fixed to one end of the sliding rod 25 of the annular plate 21. A limiting plate 27 is fixed to the surface of the sliding rod 25 in the sliding groove 24. A spring 28 is sleeved on the outside of the sliding rod 25 between the limiting plate 27 and the annular plate 21. A locking hole 210 corresponding to the sliding rod 25 is provided in the folding plate 22. Protective components 29 are provided at both ends of the annular plate 21 at positions corresponding to the pull ring 26.

[0017] Specifically, the protective component 29 includes a protective box 291. The protective box 291 is fixed at both ends of the annular plate 21 at positions corresponding to the pull ring 26. A cover plate 292 is rotatably connected to one end of the protective box 291. A handle 293 is fixed at one end of the cover plate 292. A magnetic strip 294 is fixed at the other end of the cover plate 292. A magnetic strip 295 is fixed at the lower side of one end of the protective box 291 at a position corresponding to the magnetic strip 294.

[0018] By adopting the above technical solution, when it is necessary to pull the pull ring 26, the handle 293 is used to rotate the cover plate 292 on the protective box 291. After one end of the protective box 291 is open, the pull ring 26 can be pulled. When the cover plate 292 is closed, the magnetic strip 294 at one end of the cover plate 292 can be attracted to the magnetic strip 295 at one end of the protective box 291, so as to achieve the effect of attracting and fixing the cover plate 292. The protective component 29 can protect the pull ring 26 and prevent the pull ring 26 from being bumped or accidentally pulled.

[0019] Specifically, the annular plate 21 has a sliding hole corresponding to the slide rod 25, the side of the limiting plate 27 is in contact with the inner wall of the slide groove 24, and the side of the slide rod 25 away from the pull ring 26 is set with an arc-shaped structure.

[0020] By adopting the above technical solution, the slide bar 25 can slide in the annular plate 21. The side of the slide bar 25 away from the pull ring 26 is set with an arc structure to facilitate the entry of one end of the slide bar 25 into the card hole 210 of the folding plate 22.

[0021] Specifically, the cover plate 292 and the protective box 291 are connected by a hinge, and the side of the magnetic strip 294 is flush with the side of the cover plate 292, and the side of the magnetic strip 295 is flush with the side of the protective box 291.

[0022] By adopting the above technical solution, the cover plate 292 can rotate on the protective box 291 via the hinge, and the sides of the magnetic strip 294 and magnetic strip 295 will not protrude and affect the sealing performance of the cover plate 292 when closed.

[0023] The specific usage process of this embodiment is as follows: When installing the sonic logging pipe connection structure, first install the device in a suitable position. When it is necessary to connect the first pipe 1 and the second pipe 4, pull the pull ring 26 to drive the slide rod 25 to slide in the annular plate 21. At this time, the limiting plate 27 moves along the slide groove 24, and the spring 28 is compressed. Then, insert the folding plates 22 at both ends of the first pipe 1 into the slots 23 in the annular plate 21. After releasing the pull ring 26, the spring 28 rebounds and pushes one end of the slide rod 25 into the locking hole 210 of the folding plate 22, thereby realizing the limiting and fixing of the folding plate 22 and the first pipe 1. This connection component 2 can realize the rapid assembly of the first pipe 1 and the second pipe 4, saving installation time.

[0024] In addition, when the pull ring 26 is pulled, the cover plate 292 on the protective box 291 can be opened by rotating the handle 293, so that the pull ring 26 is exposed for easy operation. When the cover plate 292 is closed, the magnetic strip 294 on it can be attracted to the magnetic strip 295 at one end of the protective box 291, so as to achieve a stable closure of the cover plate 292. The protective component 29 effectively prevents the pull ring 26 from being bumped or accidentally operated.

[0025] Example 2: The difference between this embodiment and embodiment 1 is that the sealing component 3 includes a fixing ring 32, a fixing ring 32 is fixed at one end inside the first pipe 1, a connecting plate 33 is fixed at one end of the fixing ring 32, an arc-shaped side plate 34 is fixed at the other end of the connecting plate 33, and a rubber pad 31 is fixed at one end inside the second pipe 4 near the first pipe 1.

[0026] By adopting the above technical solution, when the first pipe 1 and the second pipe 4 are assembled, the connecting plate 33 at one end of the fixing ring 32 inside the first pipe 1 is inserted into the second pipe 4 through the arc-shaped side plate 34. The arc-shaped side plate 34 facilitates the entry of the connecting plate 33 into the second pipe 4. When the connecting plate 33 enters the second pipe 4, the side of the connecting plate 33 squeezes the rubber pad 31, thereby making the sealing between the first pipe 1 and the second pipe 4 better after assembly.

[0027] Specifically, the sealing assembly 3 also includes positioning posts 35. Several positioning posts 35 are fixed at one end of the first pipe 1 near the second pipe 4, and a positioning groove 36 corresponding to the positioning posts 35 is opened at one end of the second pipe 4.

[0028] By adopting the above technical solution, when the first pipe 1 and the second pipe 4 are installed, a number of positioning posts 35 at one end of the first pipe 1 enter the positioning groove 36 at one end of the second pipe 4. Setting up the positioning posts 35 and the positioning groove 36 can play a positioning role in the assembly of the first pipe 1 and the second pipe 4, and at the same time make the assembly between the first pipe 1 and the second pipe 4 more stable.

[0029] Specifically, the side of the positioning post 35 near the second pipe 4 is set with an arc-shaped structure. After the positioning post 35 is inserted into the positioning groove 36, the side of the positioning post 35 fits against the inner wall of the positioning groove 36.

[0030] By adopting the above technical solution, the positioning post 35 is easy to insert into the positioning groove 36, and the positioning post 35 is more stable in the positioning groove 36 after being inserted into it.

[0031] In this embodiment, when the first pipe 1 is connected to the second pipe 4, the initial alignment and positioning are achieved through the cooperation of the positioning post 35 and the positioning groove 36, which not only ensures the assembly accuracy but also enhances the stability of the connection.

[0032] Subsequently, the connecting plate 33 inside the first pipe 1 is smoothly inserted into the second pipe 4 under the guidance of the arc-shaped side plate 34 at its end. During the insertion process, the side of the connecting plate 33 continuously squeezes and fixes the rubber pad 31 inside the second pipe 4, thereby forming a tight sealing interface at the joint of the two pipes.

[0033] The structure and working principle of the first pipe 1 and the second pipe 4 in this utility model have been disclosed in a sonic logging pipe connection structure disclosed in Chinese Patent Publication No. CN222893689U.

[0034] The working principle and usage process of this utility model are as follows: When installing the sonic logging pipe connection structure, install the device in a suitable position. When connecting the first pipe 1 and the second pipe 4, pull the pull ring 26 outward, causing the slide rod 25 to slide within the annular plate 21. The limiting plate 27 moves along the slide groove 24, and the spring 28 is compressed. Then, insert the folding plates 22 at both ends of the first pipe 1 into the slots 23 in the annular plate 21. After releasing the pull ring 26, the spring 28 rebounds, pushing one end of the slide rod 25 into the locking hole 210 of the folding plate 22, thereby locking the folding plate 22 and completing the quick connection and fixation of the first pipe 1 and the second pipe 4.

[0035] When the pull ring 26 needs to be pulled, the cover 292 on the protective box 291 can be turned by the handle 293 to expose the pull ring 26. After use, the cover 292 is closed, and the magnetic strip 294 at one end can attract each other with the magnetic strip 295 on the protective box 291 to achieve a stable closure of the cover 292. The protective component 29 can prevent the pull ring 26 from being bumped or accidentally pulled.

[0036] During the pipe connection process, the positioning post 35 at the front end of the first pipe 1 is first inserted into the positioning groove 36 at the end of the second pipe 4 to achieve preliminary alignment and positioning, thereby enhancing connection stability. At the same time, the connecting plate 33 inside the first pipe 1 is smoothly inserted into the second pipe 4 under the guidance of the arc-shaped side plate 34 at its end. During the insertion process, the side of the connecting plate 33 continuously presses against the rubber gasket 31 inside the second pipe 4 to form a reliable seal and ensure the sealing performance of the connection.

[0037] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
