When the pipeline needs to be repaired, they cannot be quickly disassembled. When connecting, socket-type fasteners need to align the flange ring at the pipeline connection position, which is difficult to operate. When repairing the flange ring, the entire fastener needs to be disassembled, and the operation steps are complicated. Utility Model Content

[0004] The purpose of the utility model is to provide a connection fastener for oil pipelines to prevent deformation and overload, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a connecting fastener for preventing deformation and overload of an oil pipeline, comprising a pipeline, wherein four positioning clamps are detachably installed on the outer surface of the pipeline, two of the positioning clamps form a group, and two support screws are commonly connected between the two positioning clamps in each group, and four connectors are rotatably sleeved on the outer surfaces of the two support screws, wherein two of the connectors form a group, one end of the two connectors in one group is commonly connected to a first protective shell, and one end of the two connectors in the other group is commonly connected to a second protective shell, a first flange ring protector is installed at one end of the first protective shell near the position of the second protective shell, and a second flange ring protector is installed at one end of the second protective shell near the position of the first protective shell.

[0006] Preferably, the two groups of positioning clamps are respectively located at the top and bottom ends of the pipe, and two holes are provided on both sides of the opposite ends of each group of two positioning clamps. Screws are detachably installed inside the holes, and the holes match the screws so that the corresponding two positioning clamps can be fixed to the outer surface of the pipe by the screws.

[0007] Preferably, one end of the first protective shell and the second protective shell is threadedly connected to a reinforcement block near the outer surface of the corresponding positioning clamp support screw. When the first protective shell and the second protective shell move on the outer surface of the support screw, so that the first flange ring protector and the second flange ring protector are located outside the flange ring at the pipeline connection position, the reinforcement block is twisted to contact the first protective shell and the second protective shell to reinforce them.

[0008] Preferably, four fixing screws are installed at one end of the second flange ring protector toward the first flange ring protector, and when the second flange ring protector contacts the first flange ring protector, the fixing screws can fix the first flange ring protector.

[0009] Preferably, four holes are provided through one end of the first flange ring protector, and the holes match the fixing screws. When the second flange ring protector is installed with the first flange ring protector, the fixing screws pass through the corresponding holes, and the fixing nuts are installed at the extended ends of the fixing screws to fix the first flange ring protector.

[0010] Preferably, the top of the screw extends out of an upper positioning clamp, and the extended end of the screw is installed with a hexagonal nut. When installing the positioning clamp, the screw and the hexagonal nut are used in conjunction to install the positioning clamp tightly to prevent it from falling off.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The oil pipeline deformation and overload prevention connecting fastener drives the corresponding first flange ring protector and second flange ring protector to move through the movable first protective shell and second protective shell.

[0019] like Figures 1 to 3 As shown, the connecting fastener for preventing deformation and overload of the oil pipeline in this embodiment includes a pipeline 1, and four positioning clamps 2 are detachably installed on the outer surface of the pipeline 1. Two positioning clamps 2 form a group, and the two groups of positioning clamps 2 are respectively located at the top and bottom of the pipeline 1. Two supporting screws 8 are commonly connected between the two positioning clamps 2 in each group. Four connectors 10 are rotatably sleeved on the outer surfaces of the two supporting screws 8. Two connectors 10 form a group, and one end of the two connectors 10 in one group is commonly connected to the first protective shell 3, and one end of the two connectors 10 in the other group is commonly connected to the second protective shell 4. When the two groups of positioning clamps 2 are fixed to the outside of the pipeline 1, the first protective shell 3 and the second protective shell 4 are in contact with the outer surface of the pipeline 1, The outer surface of the pipeline 1 is protected. The material of the first protective shell 3 and the second protective shell 4 are both carbon steel with moderate hardness and certain mechanical strength to prevent the internal pressure of the pipeline 1 from being excessive near the connection position and causing deformation of the pipeline 1. A first flange ring protector 12 is installed at one end of the first protective shell 3 near the position of the second protective shell 4, and a second flange ring protector 11 is installed at one end of the second protective shell 4 near the position of the first protective shell 3. The first protective shell 3 and the second protective shell 4 perform linear motion on the outer surface of the pipeline 1 through the connector 10 and the support screw 8, so that the first flange ring protector 12 and the second flange ring protector 11 move to the flange ring position at the connection position of the pipeline 1 to protect the flange ring of the pipeline 1.

[0020] Specifically, the two groups of positioning clamps 2 are respectively located at the top and bottom ends of the pipe 1. Two holes 6 are provided on both sides of the opposite ends of each group of two positioning clamps 2. Screws 7 are detachably installed inside the holes 6. The holes 6 match the screws 7 so that the corresponding two positioning clamps 2 can be fixed to the outer surface of the pipe 1 by the screws 7.

[0021] Furthermore, one end of the first protective shell 3 and the second protective shell 4 is threadedly connected to the outer surface of the support screw 8 of the corresponding positioning clamp 2.

[0024] Furthermore, the top of the screw 7 extends out of the upper positioning clamp 2, and the extended end of the screw 7 is installed with a hexagonal nut 5. When installing the positioning clamp 2, the screw 7 and the hexagonal nut 5 are used in conjunction with each other to tightly install the positioning clamp 2 to prevent it from falling off.

[0025] The method of using this embodiment is as follows: when installing the connecting fasteners, two sets of positioning clamps 2 are installed at both ends of the connection position of the pipe 1 through screws 7 and hexagonal nuts 5, so that the two sets of first protective shells 3 and second protective shells 4 are respectively located on both sides of the flange ring, and then the first protective shell 3 and the second protective shell 4 are respectively pushed to the position of the flange ring, so that the second flange ring protector 11 and the first flange ring protector 12 protect the outside of the flange ring. At this time, the fixing screw 14 passes through the corresponding jack 13, and then the fixing nut is installed on the extended end of the fixing screw 14 to fix the second flange ring protector 11 and the first flange ring protector 12. Finally, the twisting reinforcement block 9 is twisted to contact the first protective shell 3 and the second protective shell 4 to reinforce them.
