DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0023] See also Figures 1 to 4 The embodiment of the utility model provides a fiber oil pipe connection assembly for oil fields, and the fiber oil pipe connection assembly for oil fields includes a pipe body 1, an insertion tube 2 and a sleeve tube 3.

[0024] In the embodiments of the present invention, please refer to Figures 1 to 4 The two ends of the tube body 1 are respectively fixedly embedded with a coaxially arranged plug-in tube 2 and a sleeve tube 3, and the plug-in tube 2 and the sleeve tube 3 are adapted to each other, and a plurality of annularly distributed and axially arranged plug-in plates 21 are fixedly embedded on the outer tube wall of the plug-in tube 2, and a snap-on inlay 21a is provided on the plate head of each of the plug-in plates 21, and a plurality of annularly distributed and axially arranged grooves 3a are provided on the inner tube wall of the sleeve tube 3, and a steel ball joint 31 is fixedly embedded at the bottom of each of the grooves 3a, a rubber sleeve is fixedly embedded in the snap-on inlay 21a, and the rubber sleeve is interference fit with the steel ball joint 31, and the plug-in plate 21 and the groove 3a match each other.

[0025] It should be noted that: when the tube bodies 1 are docked, the insertion plate 21 is kept in one-to-one correspondence with the groove 3a, and the insertion tube 2 on the tube body 1 is inserted into the sleeve tube 3 in the adjacent tube body 1. At this time, the insertion plate 21 slides into the groove 3a, and the steel ball connector 31 on the groove 3a is snapped into the snap-in groove 21a on the corresponding insertion plate 21, thereby completing the docking of the two tube bodies 1. The two tube bodies 1 are connected in a snap-in manner through the steel ball connector 31 and the snap-in groove 21a. The operation is simple and convenient. Subsequently, the steel ball connector 31 can be slipped out of the snap-in groove 21a by pulling out one side of the tube body 1, and disassembly is easy.

[0026] Furthermore, two symmetrically distributed annular hollow cylinders 4 are fixedly sleeved on the pipe body 1, and a plurality of annularly distributed and radially arranged ears 6 are fixedly installed on the two annular hollow cylinders 4, and the ears 6 on the two annular hollow cylinders 4 correspond to each other one by one. In order to improve the firmness of the pipe body 1 after docking, the two adjacent pipe bodies 1 can be plugged in by the insertion tube 2 and the sleeve tube 3 and fixedly connected with the steel ball joint 31 by the snap-fitting groove 21a, and then the corresponding ears 6 on the two adjacent pipe bodies 1 can be fixed by bolts, thereby greatly improving the firmness of the docking of the fiber oil pipe.

[0027] Among them, the ear piece 6 arranged on the annular hollow tube 4 can also be used as a lifting connection piece for lifting the pipe body 1, and the ear piece 6 located below the two annular hollow tubes 4 of the pipe body 1 can also be used as a footrest for the pipe body 1, thereby avoiding the friction between the pipe body 1 and the ground during transportation and installation, and reducing the hidden danger of friction damage to the pipe body 1.

[0028] In the embodiments of the present invention, please refer to Figures 1 to 4 The tube openings of the two annular hollow tubes 4 are arranged back to back, and each of the tube openings of the annular hollow tubes 4 is a threaded opening 41. A protective component 5 is arranged in any one of the annular hollow tubes 4, and the protective component 5 includes an elastic pleated protective cloth 51, one end of the elastic pleated protective cloth 51 is fixedly embedded on the inner tube wall of the annular hollow tube 4, and a rotating ring 52 is fixedly installed on the other end of the elastic pleated protective cloth 51, and a rotatably connected threaded ring 53 is installed on the outer ring surface of the rotating ring 52, and the threaded ring 53 is threadedly connected to the threaded opening 41.

[0029] It should be noted that when the tube body 1 is transported or stored, the threaded ring 53 is screwed into the annular hollow cylinder 4 where the elastic pleated protective cloth 51 is installed, so that the threaded ring 53 presses the elastic pleated protective cloth 51 so that the elastic pleated protective cloth 51 is located in the annular hollow cylinder 4 for storage;

[0030] When the two tube bodies 1 are connected, the threaded ring 53 is screwed out and the elastic pleated protective cloth 51 is stretched, so that the elastic pleated protective cloth 51 can cover the connecting ends of the two tube bodies 1. Subsequently, the threaded ring 53 is inserted into the threaded opening 41 of the annular hollow cylinder 4 on the adjacent tube body 1, so that the stretched elastic pleated protective cloth 51 can stably and effectively protect the connection between the two tube bodies 1.

[0031] The working principle of the fiber oil pipe connection assembly for oil fields provided by the utility model is as follows:

[0032] When the pipe bodies 1 are butted together, the plug-in tube 2 on the pipe body 1 is kept corresponding to the groove 3a one by one, and the plug-in tube 2 on the pipe body 1 is plugged into the sleeve tube 3 in the adjacent pipe body 1. At this time, the plug-in plate 21 slides into the groove 3a, and the steel ball joint 31 on the groove 3a is snapped into the buckle inlay 21a on the corresponding plug-in plate 21, thereby completing the butt joint of the two pipe bodies 1. The two pipe bodies 1 are connected in a buckle-type manner through the steel ball joint 31 and the buckle inlay 21a. The operation is simple and convenient. Subsequently, the steel ball joint 31 can be slipped off from the buckle inlay 21a by pulling out one side of the pipe body 1, and the disassembly is simple. In order to improve the firmness of the pipe bodies 1 after butt joint, the two adjacent pipe bodies 1 can be plugged in through the plug-in tube 2 and the sleeve tube 3 and fixedly snapped with the buckle inlay 21a and the steel ball joint 31, and then the corresponding ear pieces 6 on the two adjacent pipe bodies 1 can be fixed by bolts, thereby greatly improving the firmness of the butt joint of the fiber oil pipe.

[0033] When the two tube bodies 1 are connected, the threaded ring 53 is screwed out and the elastic pleated protective cloth 51 is stretched, so that the elastic pleated protective cloth 51 can cover the connecting ends of the two tube bodies 1. Subsequently, the threaded ring 53 is inserted into the threaded opening 41 of the annular hollow cylinder 4 on the adjacent tube body 1, so that the stretched elastic pleated protective cloth 51 can stably and effectively protect the connection between the two tube bodies 1.

[0034] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
