DETAILED DESCRIPTION
[0014] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0015] Reference Figure 1-Figure 3As shown, a variable buckle joint for oil fields with high sealing performance includes a joint body 1, a shell 2 and a screw 17. A threaded hole 3 is provided in the shell 2, and the threaded hole 3 is threadedly connected to the arc-shaped outer surface of the joint body 1. The arc-shaped upper surfaces at both ends of the shell 2 are fixedly connected with screw nuts 8, and the internal threads of the screw nuts 8 are connected with screw rods 9. The screw rods 9 penetrate and are rotatably connected to the arc-shaped upper surface of the shell 2. The upper surface of the screw rod 9 is fixedly connected with a knob 10, and the lower end of the screw rod 9 is fixedly connected with a bearing seat 11, and the lower surface of the bearing seat 11 is fixedly connected with an upper arc plate 14. The upper surface of the upper arc plate 14 is symmetrically fixedly connected with a first slide rod 12, and the first slide rod 12 penetrates and is slidably connected to the arc-shaped upper surface of the shell 2. The upper surface of the first slide rod 12 is fixedly connected with a limiting block 13, and the first slide rod 12 is symmetrically distributed on both sides of the screw rod 9 at 45°. The lower surfaces at both ends of the shell 2 are uniform. Three second slide bars 19 are slidably connected through the three second slide bars 19, and the upper surfaces of the three second slide bars 19 are fixedly connected with the lower arc plate 18. The three second slide bars 19 are slidably connected with springs 20, and the lower surfaces of the three second slide bars 19 are fixedly connected with blocks 21. The upper ends of the springs 20 are in contact with the lower arc plate 18, and the lower ends of the springs 20 are in contact with the arc-shaped inner surface of the shell 2. When the oil pipe is inserted into the joints on both sides, the upper arc plate 14 presses the oil pipe downward under the cooperation of the screw rod 9 and the first slide bar 12. At the same time, the lower arc plate 18 gives the oil pipe an upward force under the cooperation of the second slide bar 19 and the spring 20, and the pipeline is fixed by the extrusion of the upper and lower arc plates. By the fixed sealing device arranged at both ends of the shell, the oil pipes at both ends are fixed without threaded connection. The pipeline is fixed by the extrusion of the upper and lower arc plates, which solves the inconvenience caused by the threaded connection.
[0016] A first sealing ring 4 is fixedly connected to the inside of one end of the shell 2, and a second sealing ring 5 is fixedly connected to the inside of the other end of the shell 2. A first sealing layer 6 is fixedly connected to the annular inner surface of one end of the shell 2, and a second sealing layer 7 is fixedly connected to the annular inner surface of the other end of the shell 2. The sealing rings and sealing layers arranged inside the two ends of the shell are used to achieve a sealing effect to prevent the oil in the pipeline from flowing out of the pipeline and causing waste. A square groove 15 is opened on the side of one end of the joint body 1, and a filter screen 16 is fixedly connected in the square groove 15. The filter screen 16 is threadedly connected to the side of the joint body 1 by screws 17. The filter screen 16 arranged on the side surface of the joint can perform preliminary filtering of impurities in the oil field to prevent impurities from entering the oil tank, saving time for subsequent work.
[0017] When the oil pipe is inserted into the joints on both sides, the knob 10 is turned, and the knob 10 drives the screw rod 9 to rotate, and the screw rod 9 drives the upper arc plate 14 to move. The upper arc plate 14 presses the oil pipe downward under the cooperation of the screw rod 9 and the first slide bar 12, and at the same time, the lower arc plate 18 gives the oil pipe an upward force under the cooperation of the second slide bar 19 and the spring 20. The pipeline is fixed by squeezing the upper and lower arc plates. When the pipelines on both sides are fixed, oil flows in the oil pipe, and the oil is filtered by the filter screen 16 arranged on the side of the joint. The connection between the oil pipe and the joint is sealed by the sealing device arranged in the shell 2 to prevent the oil in the pipeline from flowing out of the pipeline and causing waste. The fixed sealing devices arranged at both ends of the shell do not need to be threaded to fix the oil pipes at both ends. The pipeline is fixed by squeezing the upper and lower arc plates, which solves the inconvenience caused by the threaded connection. The impurities in the oil field are preliminarily filtered by the filter screen arranged on the side surface of the joint to prevent impurities from entering the oil tank, saving time for subsequent work.
