Description

Technical Field

[0001] This utility model belongs to the field of oil and gas recovery technology, and specifically relates to an oil and gas recovery quick connection device. Background Technology

[0002] In the field of oil and gas recovery, the stability of pipeline connections directly affects the overall safety and efficiency of the system. Existing technologies, such as the patent with publication number CN212174884U, while improving oil and gas recovery efficiency through a multi-stage adsorption structure, still rely on traditional quick-connect couplings for direct fixing of pipeline connections.

[0003] This type of design has significant drawbacks: the connection lacks a protective structure against external interference, and long-term exposure to vibration, torque, or external impact can easily cause the joint to loosen, leading to the risk of oil and gas leakage.

[0004] Therefore, there is an urgent need for an oil and gas recovery pipeline connection device that combines quick connection and impact resistance to prevent loosening. Utility Model Content

[0005] The purpose of this invention is to provide a quick connection device for oil and gas recovery to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick connection device for oil and gas recovery, comprising a pipe A and a pipe B, a quick connector A fixedly connected to the open end of the pipe A, and a quick connector B fixedly connected to the open position of the pipe B, wherein a support component is installed on the outside of the pipe A, and a limit component is installed on the outside of the pipe B.

[0007] The support assembly includes a support ring fitted around the outside of the pipe A and fixedly connected, a protective plate symmetrically installed on the end face of the support ring, an assembly ring fixedly connected to the end of the protective plate, and a positioning groove and a guide groove formed on the surface of the assembly ring.

[0008] Preferably, the protective plate is located on the outside of pipe A, and a warning sticker is adhered to the outer surface of the protective plate.

[0009] Preferably, the limiting component includes a limiting ring sleeved on the outside of the pipe B and fixedly connected, and a rubber ring adhered to the end face of the limiting ring.

[0010] Preferably, a bearing seat is rotatably connected to the surface of the limiting ring, and a traction frame is fixedly connected to the surface of the bearing seat.

[0011] Preferably, the end of the traction frame is fixedly connected with a positioning pin, and the positioning pin and the positioning slot are inserted into each other.

[0012] Preferably, a push handle is fixedly connected to the surface of the traction frame, and the surface of the push handle is provided with anti-slip texture.

[0013] Preferably, the positioning groove is located in the middle of the guide groove, and the positioning groove and the guide groove are connected.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Dual fixing mechanism enhances anti-loosening performance: The assembly ring in the support component and the rubber ring in the limiting component form the first-level buffer fixing through sliding contact, effectively absorbing axial impact; the positioning pin at the end of the traction frame is engaged with the guide groove and positioning groove, and the second-level mechanical locking is achieved by turning the push handle, which significantly enhances the connection's tensile and torsional resistance.

[0016] 2. Easy installation and maintenance: The rotating connection design between the bearing seat and the traction frame allows the positioning pin to be quickly aligned with the guide groove, simplifying the assembly process; the fixing method between the limit ring and pipe B adopts a modular design, which facilitates partial replacement and reduces maintenance costs.
