Description

Technical Field

[0001] This utility model relates to the field of insulating sleeve technology, and more specifically, to a protective sleeve for oil and gas well cables. Background Technology

[0002] Cable conduits, also known as protective pipes or conduits, are pipes used in electrical installations to protect wires and cables, allowing them to be inserted and replaced. Traditional cable insulation sleeves cannot be reinforced at the connection points, and because cable insulation sleeves are prone to bending and damage at the connection points, their service life is reduced, which also affects the corresponding work efficiency.

[0003] To address the aforementioned issues, patent document publication number CN220732276U discloses an insulating sleeve for cable protection, comprising a main body, wherein three sets of fixing tubes are fixedly connected inside the main body, and each of the three sets of fixing tubes is slidably connected to a receiving rod.

[0004] However, in actual use, it still has some drawbacks. For example, the above-mentioned protective sleeve drives the rotating block and the upper limit block to rotate through the hinge seat, so that the upper limit block is in contact with the surface of the main body, and the first and second receiving plates are in contact. The bolts are inserted into the interior of the first and second receiving plates and fixed with nuts, so that the first and second receiving plates are tightly in contact, thereby making the upper limit block and the lower limit block tightly in contact with the main body, thus reinforcing the connection. However, the upper limit block and the lower limit block are fixed by bolts and nuts, but they are prone to loosening under vibration or long-term use, which may still lead to the risk of damage at the connection. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a protective sleeve for oil and gas well cables to solve the problem that the upper limit block and lower limit block, which are fixed by bolts and nuts, still have the risk of loosening.

[0009] The fixed plate comprises two plates, which are disposed opposite to each other at the top and bottom of the connecting column. A spring is fixedly connected to the surface of each fixed plate. A movable plate is fixedly connected to the bottom end of one spring. The inner wall of the movable plate is slidably connected to the surface of the connecting column. A mounting seat is provided on one side of the movable plate along its length. A sleeve post is rotatably mounted inside the mounting seat. The sleeve post is a hollow structure. The bottom surface of the mounting seat is in contact with the top surface of the first receiving plate.

[0010] The system also includes a second movable plate, which is slidably mounted on the surface of the connecting column. The bottom surface of the second movable plate is fixedly connected to the top of another spring. A second mounting seat is provided on one side of the second movable plate along its length. The top surface of the second mounting seat is in contact with the bottom surface of the second receiving plate. A second sleeve post is provided inside the second mounting seat, and a fitting pad is provided on the inner wall of the second sleeve post.

[0011] The mounting base has two opposing fixed frames on its top. A connecting end is fixedly installed on the top of the fixed frame. A torsion spring is fixedly connected inside the connecting end. A bottom post is fixedly connected to the bottom end of the torsion spring. The outer wall of the top of the bottom post is rotatably connected to the connecting end. The bottom end of the bottom post is fixedly connected to the center of the top surface of the sleeve post.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] In the above scheme, after the first and second receiving plates are fixed together with bolts, the connecting column is rotated horizontally by holding the fixing plate, so that the first and second mounting seats move synchronously and are respectively located above the first and second receiving plates. Then, the elasticity of the springs on the surface of the fixing plate is used to make the first and second movable plates move vertically, so that the first and second mounting seats are respectively in contact with the surfaces of the first and second receiving plates. This allows the first and second sleeve columns to engage with the bolt heads and bolt parts, thereby limiting and tightening the bolts. This prevents the bolts and nuts from loosening during long-term use, ensures that the upper limit block and the lower limit block can be tightly connected, and improves the practicality of the device.

[0014] When the first sleeve post is sleeved with the bolt head, the torsion spring set in the connection end can provide the bottom post and the bolt with the same tightening force during the sleeve post and bolt sleeve process, thereby further tightening the bolt on the basis of sleeve connection, ensuring that the protective sleeve and the cable are firmly connected.
