Technical Field
[0001] This utility model relates to the field of oil well testing technology, specifically to a high-airtightness oil well testing connection device that can be quickly connected. Background Technology
[0002] Oil wells are the core facilities for oil and gas resource development, undertaking the crucial task of extracting oil and gas from underground reservoirs and transporting them to the surface. Their role spans the entire process of oil and gas exploration, development, and production. Testing oil wells is extremely important. High-airtightness oil well testing connection equipment is required during oil well testing. However, when using this equipment, encountering bends where connection is impossible can cause significant inconvenience for operators. Therefore, it is necessary to install auxiliary hoses on the high-airtightness oil well testing connection equipment. These auxiliary hoses are connected to the high-airtightness oil well testing connection equipment, and the end of the auxiliary hose is then connected to the required position. For example, the Chinese patent application No. 201821388529.5, filed on August 28, 2018, describes an oil well fluid level tester connection device. This device allows for quick connection during use, and the probe extension length can be adjusted according to actual needs, making the operation process simple and fast.
[0003] When the high-airtightness oil well testing connection equipment is connected normally and the auxiliary hose is not needed, the high-airtightness oil well testing connection equipment and the auxiliary hose need to be disassembled. However, the device in the above application does not have a structure to assist in disassembly during use, which reduces the work efficiency of the staff and brings unnecessary trouble to the staff. Utility Model Content
[0004] The purpose of this utility model is to provide a high-airtightness oil well testing connection device that can be quickly connected, so as to solve the problem mentioned in the background art that the lack of an auxiliary disassembly structure during use reduces the work efficiency of the staff and brings unnecessary trouble to the staff.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-airtightness oil well testing connection device capable of rapid docking, comprising a working pipe and an auxiliary pipe, wherein a connecting plate is fixedly connected to the surface of the working pipe, and a working plate is fixedly connected to the surface of the auxiliary pipe, and the working plate and the connecting plate are interlocked; a flexible hose is fixedly connected to the lower surface of the auxiliary pipe, and the end of the flexible hose is connected to an external adapter; an installation groove is provided on the surface of the connecting plate, and a locking block is slidably disposed inside the connecting plate, and a handle is fixedly connected to the end of the locking block; an outer frame is fixedly connected to the upper surface of the connecting plate, and a force-bearing plate is slidably disposed inside the outer frame.
[0006] Preferably, the upper surface of the work plate is fixedly connected to a vertical plate, and the vertical plates are symmetrically distributed on both sides of the work plate, and the surface of the vertical plate is provided with a slot.
[0007] Preferably, the card block extends through the interior of the connecting plate, and the card block corresponds one-to-one with the card slot, and the lower surface of the card block is inclined.
[0008] Preferably, a first spring that provides elastic reset is fixedly connected to the surface of the handle, and the other side of the first spring is fixedly connected to the outer surface of the connecting plate.
[0009] Preferably, a column is fixedly connected to the inner wall of the outer frame, and the force-bearing plate is sleeved and connected to the surface of the column, and the force-bearing plate corresponds one-to-one with the vertical plate.
[0010] Preferably, limit blocks are fixedly connected to both the upper and lower sides of the card block, and the connecting plate has limit grooves inside that correspond one-to-one with the limit blocks.
[0011] Preferably, a second spring that provides elastic reset is fixedly connected to the upper surface of the force-bearing plate, and the other side of the second spring is fixedly connected to the upper surface of the force-bearing plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are: the high airtightness oil well testing connection device that can be quickly connected adopts a novel structural design, the specific details of which are as follows:
[0013] (1) When the auxiliary pipe and working pipe need to be connected during use, the vertical plate is inserted into the installation groove. At this time, the locking block will be pushed and moved in the direction of stretching the first spring. After the working plate contacts the bottom of the working pipe, the locking block and the locking groove are in the same horizontal direction. Then the locking block will enter the locking groove under the action of the first spring, that is, the working pipe and the auxiliary pipe have been connected. The operation process is quick and convenient.
[0014] Furthermore, during the movement of the card block, the card block will drive the limit block to slide inside the limit groove. The limit block and the limit groove limit the movement distance of the card block and ensure the stability of the card block's operation.
[0015] (2) The high airtightness oil well test connection equipment that can be quickly connected can be used to separate the working pipe and the auxiliary pipe by pulling the handle. When the handle moves the end of the locking block out of the slot, the connecting plate and the working plate are not locked. At this time, the working pipe and the auxiliary pipe can be separated, which is highly efficient.
[0016] (3) In the process of docking, the vertical plate will push the force plate. At this time, the force plate will rise inside the outer frame, and the second spring will be squeezed. That is, during the docking process of the working pipe and the auxiliary pipe, the second spring is always in a squeezed state. After the end of the card block moves out of the slot, the force plate will descend under the action of the second spring. At this time, the force plate plays the role of accelerating the separation of the working pipe and the auxiliary pipe, making the disassembly process more convenient.
[0017] Furthermore, during the movement of the load-bearing plate, the column causes the load-bearing plate to move only in the vertical direction. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] This utility model provides the following technical solution: a high-airtightness oil well testing connection device that can be quickly connected.
[0028] Example 1: The locking block 5 and the slot 9 allow the connecting plate 4 and the working plate 7 to quickly engage and lock together. Figures 1-6 As shown, a high-airtightness oil well testing connection device that can be quickly connected includes a working pipe 1 and an auxiliary pipe 2. A connecting plate 4 is fixedly connected to the surface of the working pipe 1, and a working plate 7 is fixedly connected to the surface of the auxiliary pipe 2. The working plate 7 and the connecting plate 4 are interlocked. A flexible hose 3 is fixedly connected to the lower surface of the auxiliary pipe 2, and the end of the flexible hose 3 is connected to an external adapter. An installation groove 13 is opened on the surface of the connecting plate 4, and a locking block 5 is slidably arranged inside the connecting plate 4. A handle 6 is fixedly connected to the end of the locking block 5. A vertical plate 8 is fixedly connected to the upper surface of the working plate 7, and the vertical plates 8 are symmetrically distributed on both sides of the working plate 7. A locking groove 9 is opened on the surface of the vertical plate 8.
[0029] The locking block 5 passes through the interior of the connecting plate 4, and the locking block 5 corresponds one-to-one with the locking slot 9. The lower surface of the locking block 5 is inclined. The surface of the handle 6 is fixedly connected to a first spring 16 that plays an elastic reset role, and the other side of the first spring 16 is fixedly connected to the outer surface of the connecting plate 4.
[0030] A column 15 is fixedly connected to the inner wall of the outer frame 10, and a force plate 14 is sleeved on the surface of the column 15. The force plate 14 corresponds to the vertical plate 8. Limiting blocks 12 are fixedly connected to both the upper and lower sides of the card block 5. The connecting plate 4 has a limiting groove 11 that corresponds to the limiting block 12.
[0031] During use, when it is necessary to connect the auxiliary tube 2 and the working tube 1, insert the vertical plate 8 into the mounting slot 13. At this time, the locking block 5 will be pushed, and the locking block 5 will drive the handle 6 to move in the direction of stretching the first spring 16. After the working plate 7 contacts the bottom of the working tube 1, the locking block 5 and the locking slot 9 are in the same horizontal direction. Then, the locking block 5 will enter the locking slot 9 under the action of the first spring 16, that is, the working tube 1 and the auxiliary tube 2 have been connected. The operation process is quick and convenient. During the movement of the locking block 5, the locking block 5 will drive the limiting block 12 to slide inside the limiting slot 11. The limiting block 12 and the limiting slot 11 limit the movement distance of the locking block 5 and ensure the stability of the locking block 5.
[0032] When it is necessary to separate the working tube 1 and the auxiliary tube 2, simply pull the handle 6. After the handle 6 moves the end of the locking block 5 out of the slot 9, the connecting plate 4 and the working plate 7 are no longer locked. At this time, the working tube 1 and the auxiliary tube 2 can be separated, resulting in high work efficiency.
[0033] Example 2: Unlike Example 1, the force-bearing plate 14 and the second spring 17 make the separation of the working tube 1 and the auxiliary tube 2 smoother. Figure 6 and Figure 7 As shown, an outer frame 10 is fixedly connected to the upper surface of the connecting plate 4, and a force-bearing plate 14 is slidably arranged inside the outer frame 10. A second spring 17 that plays an elastic reset role is fixedly connected to the upper surface of the force-bearing plate 14, and the other side of the second spring 17 is fixedly connected to the upper surface of the force-bearing plate 14.
[0034] During the docking process, the vertical plate 8 pushes the force plate 14, which rises inside the outer frame 10. This causes the second spring 17 to be compressed. In other words, during the docking process of the working tube 1 and the auxiliary tube 2, the second spring 17 is always in a compressed state. After the end of the locking block 5 moves out of the slot 9, the force plate 14 descends under the action of the second spring 17. At this time, the force plate 14 accelerates the separation of the working tube 1 and the auxiliary tube 2, making the disassembly process more convenient. During the movement of the force plate 14, the column 15 causes the force plate 14 to move only in the vertical direction.
[0035] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
