Description
Technical Field
[0001] This invention belongs to the field of hydraulic component technology, specifically a stainless steel oil pipe connector for a truck cab tilting system. Background Technology
[0002] The tilting cab of a truck greatly simplifies vehicle maintenance and is one of the classic designs in the truck industry. Currently, almost 100% of heavy-duty trucks with cabs support tilting functionality, and even light trucks, which previously rarely had this feature, are increasingly using tilting technology. A hydraulic tilting system, as the name suggests, relies on hydraulic power to lift the cab. In terms of power source, hydraulic tilting systems are divided into manual and electric types. Since the cab tilting is infrequent and manpower is sufficient, most heavy-duty trucks now use manual hydraulic tilting systems. The biggest advantage of a hydraulic tilting system is its large lifting force; it can easily lift any number of cabs, which is unmatched by torsion bar power-assisted systems.
[0003] Currently, the stainless steel oil pipes used in truck cab tipping systems are connected by a crimping connection. However, this connection method requires the use of special calipers to compress and deform the oil pipes in order to achieve the connection. Each connection requires two compressions, which is inconvenient for connecting the oil pipes. Moreover, each caliper can only connect one point at a time. When multiple connections are needed, a lot of waiting time is required, which reduces work efficiency. Summary of the Invention
[0004] To overcome the shortcomings of existing technologies, this invention proposes a stainless steel hydraulic pipe connector for a truck cab tilting system. This invention primarily addresses the problem that current stainless steel hydraulic pipes use a crimp connection method, requiring the use of specialized calipers. These calipers are not only inconvenient to operate but also involve waiting time.
[0005] The technical solution adopted by this invention to solve its technical problem is as follows: This invention provides a stainless steel oil pipe connector for a truck cab tilting system, including a fixing component, a connecting pipe, a sliding component, a driving component, and a mounting component; the connecting pipe is disposed inside the fixing component; the connecting pipe passes through the middle of the fixing component; the connecting pipe is connected to the fixing component; both ends of the connecting pipe are symmetrically provided with protruding structures; the protruding structures are evenly spaced along the circumferential direction of the connecting pipe; the driving component is disposed outside the fixing component; the driving component is a cylindrical structure; the driving component is sleeved outside the fixing component; the driving component is rotatably connected to the fixing component; both ends of the driving component are symmetrically provided with mounting components; the mounting components are cylindrical structures; one end of the mounting component is provided with a connecting portion; the connecting portions are evenly spaced along the circumferential direction of the mounting component; both ends of the fixing component are symmetrically provided with connecting grooves; the connecting portions are inserted into the connecting grooves; the connecting portions are fixed to the fixing component. The connection includes: a sliding groove at one end of the mounting component; an extrusion component within the sliding groove; a sliding connection between the extrusion component and the mounting component; an inclined structure at the upper end of the extrusion component; an extrusion section at the lower end of the extrusion component; symmetrical driving structures at both ends of the driving component; symmetrically arranged sliding components at both ends of the driving component; a cylindrical structure for each sliding component; one end of each sliding component fitted onto the driving structure; a threaded connection between the sliding component and the driving structure; a mounting groove at the other end of each sliding component; evenly spaced mounting grooves along the circumference of the sliding component; a sidewall of the mounting groove fitting against the sidewall of the connection portion; a pushing structure at one end of each sliding component; evenly spaced pushing structures along the circumference of the sliding component; the pushing structure abutting against the inclined structure; a first sealing element symmetrically arranged at both ends of the connecting pipe; a first sealing element being an annular structure; and a first sealing element fitted onto the connecting pipe.
[0006] During operation, the two ends of the connecting pipe are inserted into the two oil pipes to be connected. Then, the drive component is rotated, which in turn rotates the drive structures at both ends, causing the two sliding components to move, which in turn moves the pushing structure. This exerts a force on the inclined structure, causing the extrusion component to move towards one side of the connecting pipe. The extrusion part then contacts the side of the oil pipe end, generating extrusion force. This causes the side to deform towards the protruding structure, forming a slope. Several slopes are formed at the end of the oil pipe, with the lower side of the slope contacting the protruding structure and the upper side of the slope contacting the extrusion part. The position of the slopes is then fixed, connecting the oil pipe and the connecting component. This connector allows for the connection of two oil pipes together, thus completing the oil pipe connection. Currently, most stainless steel oil pipes use crimp connections, which require the use of special calipers to compress and deform the oil pipe. Each connection requires two compressions, which is inconvenient for oil pipe connection. Furthermore, each caliper can only connect one point at a time. When multiple connections are needed, a significant amount of waiting time is required, reducing work efficiency. This connector, however, can connect two oil pipes by rotating the drive component, thus avoiding the need for special calipers and facilitating the oil pipe connection. It also eliminates the waiting time for calipers, saving connection time and improving connection efficiency.
[0007] Preferably, the distance between two adjacent protrusions is greater than the width of the extrusion portion.
[0008] By reversing the rotation of the drive component, the sliding component moves in the opposite direction, which in turn drives the pushing structure to move in the opposite direction. Under the action of the elastic component below the extruder, the extruder moves upward, causing the extrusion section to detach from the ramp. Then, force is applied to push the oil pipe to be removed, causing it to move inward towards the connector, thus detaching the ramp from the protruding structure. Rotating the oil pipe then causes the ramp to rotate, positioning it between the two protruding structures. Pulling the oil pipe outward then pulls the ramp out from between the two protruding structures, detaching the oil pipe from the connector and achieving oil pipe removal. Currently, stainless steel oil pipes, after being crimped, can only be removed through destructive removal, increasing the difficulty of oil pipe removal. The previous method of removing the oil pipe was difficult and inconvenient. However, this connector can separate the connector and the oil pipe by rotating the drive component in the opposite direction, thus facilitating the removal of the oil pipe and improving the convenience of the connector. Removing the oil pipe by destructive means will damage both the connector and the oil pipe, requiring the oil pipe to be trimmed, lengthened, and replaced with a new connector before it can be reconnected, increasing the workload of oil pipe reconnection. This connector inserts the connecting pipe into the oil pipe, rotates the connecting pipe, and then pulls the connecting pipe backward, causing the protruding structure to abut against the slope. Then, rotating the drive component causes the extrusion part to abut against the slope, thus fixing the slope and reconnecting the oil pipe, thus facilitating the reconnection of the oil pipe.
[0009] Preferably, the connecting pipe is a split structure; the connecting pipe includes a first pipe; one end of the first pipe is symmetrically provided with a sliding structure; the fixing member is symmetrically provided with guide grooves; the guide grooves are evenly spaced; the sliding structure is slidably connected in the guide groove; a connecting rod is provided on one of the upper sliding structures; one end of the connecting rod is fixedly connected to the sliding structure; the other end of the connecting rod is provided with an inclined portion; both ends of the fixing member are symmetrically provided with circular holes; the connecting rod is slidably connected in the circular holes; both ends of the fixing member are symmetrically provided with rotating parts; the upper end of the rotating part is threadedly connected to the fixing member; the lower end of the rotating part is provided with a conical structure; the conical structure abuts against the inclined portion; a first elastic element is provided on the connecting rod; the first elastic element is sleeved on the connecting rod; one end of the first elastic element abuts against the fixing member; the other end of the first elastic element abuts against the sliding structure; a second sealing element is provided between the two first pipes; the second sealing element is an annular structure; both ends of the second sealing element are respectively fixedly connected to the first pipe.
[0010] When a particular oil pipe needs to be dismantled, the driving components on the connectors at both ends of the oil pipe are rotated in the reverse direction, causing the pressing components of the connectors at both ends to detach from the ramps. Then, the rotating components on the connectors at both ends are rotated, causing the rotating components to move upward, which in turn moves the conical structure upward. Simultaneously, the driving components at both ends of the oil pipe are pushed, causing the fixing components at both ends to move closer together, which in turn moves the two No. 1 pipes closer together, causing the ramps at both ends of the oil pipe to detach from the protruding structures on the two No. 1 pipes respectively. Then, the oil pipe is rotated, causing the ramps to rotate between the two protruding structures. Then, the oil pipe is moved to one end, causing the ramp at one end to move out from between the protruding structures on a No. 1 pipe, thus pulling one end of the oil pipe out of a No. 1 pipe. Then, the oil pipe is moved in the reverse direction, causing the oil pipe to be pulled out of the No. 1 pipe at the other end, thus disconnecting both ends of the oil pipe from the No. 1 pipes at both ends respectively, thereby achieving the dismantling of both ends of the oil pipe from the connectors at both ends. This allows for the dismantling of a single oil pipe when other oil pipes cannot be moved, thus improving the convenience of dismantling a single oil pipe.
[0011] Preferably, a first sealing element is fitted onto the first pipe; one end of the first sealing element has a first bladder-like structure; the other end of the first sealing element has a second bladder-like structure; a connecting structure is provided between the first bladder-like structure and the second bladder-like structure; the connecting structure is evenly spaced along the circumference of the first sealing element; a connecting hole is provided inside the connecting structure; one end of the connecting hole communicates with the inner cavity of the first bladder-like structure; the other end of the connecting hole communicates with the inner cavity of the second bladder-like structure; a squeezing plate is provided inside the sliding member; the squeezing plate is fixedly connected to the sliding member; the side of the squeezing plate is in contact with the side of the first bladder-like structure; a limiting member is provided outside the connecting structure; the limiting member is fitted outside the connecting structure; one end of the limiting member abuts against the squeezing member; the other end of the limiting member abuts against the first bladder-like structure; the first bladder-like structure and the second bladder-like structure are filled with an incompressible medium.
[0012] When the driving component moves the sliding component, the sliding component moves the extrusion component, thereby compressing the first bladder structure, increasing the pressure inside the first bladder structure, causing the medium inside the first bladder structure to move through the connecting hole into the second bladder structure, further increasing the pressure inside the second bladder structure, causing the sidewall of the second bladder structure to expand towards the inner wall of the oil pipe, thus sealing the gap between the first pipe and the inner wall of the oil pipe, thereby achieving a reliable seal between the oil pipe and the connecting component; when the extrusion component moves upward, it exerts a force on the pushing structure, causing the sliding component to move towards the driving component, thereby moving the extrusion plate towards the pushing structure, thereby reducing the force on the first bladder structure, causing the medium inside the second bladder structure to move towards the first bladder structure, thereby reducing the pressure inside the second bladder structure, and causing the second bladder structure to deform when the oil pipe is pulled outward, thus facilitating the ramp to slide over the surface of the second bladder structure, facilitating the pull-out of the oil pipe, and facilitating the removal of the oil pipe.
[0013] Preferably, the first capsule-shaped structure is provided with a first elastic sheet; the first elastic sheet is evenly spaced along the circumference of the first capsule-shaped structure; the first elastic sheet is cast together with the sidewall of the first capsule-shaped structure.
[0014] By setting the first elastic plate, when the extrusion plate moves towards the driving component along with the sliding component, the first bladder-like structure expands outward under the elastic force of the first elastic plate, thereby restoring the first bladder-like structure to its original shape, and consequently the second bladder-like structure to its original shape. This separates the outer wall of the second bladder-like structure from the slope before the oil pipe is pulled out, thus avoiding scraping between the slope and the second bladder-like structure when pulling out the oil pipe, facilitating the outward pulling out of the oil pipe, and making the oil pipe removal easier. At the same time, it reduces the probability of the second bladder-like structure being damaged due to scraping with the slope, thereby reducing the probability of damage to the second bladder-like structure, which in turn reduces the probability of damage to the first seal, thus ensuring the sealing effect of the first seal and ensuring the connection quality of the oil pipe.
[0015] Preferably, the wall thickness of the second sac-like structure is less than the wall thickness of the first sac-like structure.
[0016] The wall thickness of the No. 2 bladder structure is less than that of the No. 1 bladder structure, making the No. 2 bladder structure easier to deform. This increases the fit between the No. 2 bladder structure and the inner wall of the tubing, thereby improving the sealing performance between the No. 2 bladder structure and the inner wall of the tubing, and ultimately improving the connection quality of the tubing.
[0017] Preferably, a second elastic sheet is provided in the inner wall of the second seal; the second elastic sheet is evenly spaced along the circumference of the second seal; the second elastic sheet is arc-shaped; the second elastic sheet is cast together with the inner wall of the second seal; the middle part of the second elastic sheet arches towards the side away from the axis of the second seal.
[0018] When the conical structure moves upward, the elastic force of the second elastic plate overcomes the elastic force of the first elastic element, thereby causing the first pipe to move into the oil pipe. This causes the protruding structure to detach from the lower side of the slope, thus avoiding pushing the oil pipe and causing the slope to separate from the protruding structure. This allows the oil pipe to be rotated directly and pulled out, facilitating the removal of the oil pipe and improving the convenience of the connector.
[0019] Preferably, the lower end of the extrusion part is provided with a limiting part.
[0020] When inserting the tubing into the connector, if the tubing is inserted too shortly, the slope will be reduced, thus decreasing the slope's resistance to deformation, which in turn reduces the connection strength between the tubing and the connector, and consequently, the connection quality. If the tubing is inserted too long, the slope will be increased, causing the bottom of the slope to abut against the outer wall of the first pipe, which increases the resistance to rotating and pulling out the tubing, and reduces the ease of removing the tubing. By setting a limiting part, the tubing is positioned appropriately, ensuring that the slope dimensions guarantee connection strength while facilitating tubing removal, thereby improving the convenience of the connector while ensuring connection quality.
[0021] Preferably, the end of the first pipe is provided with an inclined structure; the inclined structures are evenly spaced along the circumference of the first pipe.
[0022] By setting an inclined structure, the sidewall of the second bladder structure is limited, thereby reducing the axial deformation of the second bladder structure, increasing the radial deformation of the second bladder structure, increasing the extrusion force between the second bladder structure and the inner wall of the oil pipe, thereby improving the sealing performance between the second bladder structure and the inner wall of the oil pipe, thereby improving the sealing performance between the oil pipe and the connector, and thus improving the connection quality of the oil pipe.
[0023] The beneficial effects of this invention are as follows:
[0024] 1. In this invention, the two ends of the connecting pipe are respectively inserted into the two oil pipes to be connected. Then, the driving component is rotated, which in turn drives the driving structures at both ends to rotate, which in turn moves the two sliding components, which in turn moves the pushing structure, thereby generating a force on the inclined structure. This causes the extrusion component to move towards one side of the connecting pipe, so that the extrusion part abuts against the side of the oil pipe end, thereby generating a compressive force on the side of the oil pipe end, causing the side to deform towards the protruding structure and form a slope. This forms several slopes at the end of the oil pipe, with the lower side of the slope abutting against the protruding structure, and the upper side of the slope abutting against the extrusion part, thereby fixing the position of the slope and connecting the oil pipe to the connecting component. This connector combines two oil pipes together, thus completing the oil pipe connection. Currently, most stainless steel oil pipes use crimp connections, which require the use of special pliers to compress and deform the oil pipe. Each connection requires two compressions, which is inconvenient. Furthermore, each plier can only connect one point at a time. When multiple connections are needed, a significant amount of waiting time is required, reducing work efficiency. This connector, however, can connect two oil pipes simply by rotating the drive component, thus avoiding the need for special pliers and facilitating the connection process. It also eliminates the waiting time associated with pliers, saving connection time and improving efficiency.
[0025] 2. In this invention, the reverse rotation of the driving component causes the sliding component to move in the opposite direction, which in turn causes the pushing structure to move in the opposite direction. Under the action of the elastic component below the extruder, the extruder moves upward, causing the extrusion part to detach from the slope. Then, the oil pipe to be removed is pushed forcefully, causing it to move inward towards the connecting component, thus detaching the slope from the protruding structure. The oil pipe is then rotated, causing the slope to rotate and move between the two protruding structures. The oil pipe is then pulled outward, pulling the slope out from between the two protruding structures, thus detaching the oil pipe from the connecting pipe and achieving oil pipe removal. Currently, stainless steel oil pipes, after being crimped, can only be removed by destructive removal, increasing the complexity of oil pipe removal. The difficulty of dismantling traditional oil pipes makes removal inconvenient. However, this connector separates the connector and oil pipe by reversing the rotation of the drive component, facilitating oil pipe removal and improving the convenience of the connector. Dismantling oil pipes through destructive methods damages both the connector and the oil pipe, requiring trimming, lengthening, and replacement with a new connector for reconnection, increasing the workload. This connector inserts the connector into the oil pipe, rotates it, and then pulls it backward, causing the protruding structure to contact the slope. Rotating the drive component then causes the extrusion part to contact the slope, fixing the slope and reconnecting the oil pipe, thus facilitating reconnection.
[0026] 3. In this invention, when a certain oil pipe needs to be dismantled, the driving component on the connector at both ends of the oil pipe is rotated in the reverse direction, thereby causing the pressing component of the connector at both ends to detach from the slope. Then, the rotating component on the connector at both ends is rotated, thereby causing the rotating component to move upward, thereby causing the conical structure to move upward. Then, the driving component at both ends of the oil pipe is pushed simultaneously, thereby causing the fixing component at both ends to move closer to each other, thereby causing the two No. 1 pipes to move closer to each other, thereby causing the slope at both ends of the oil pipe to detach from the protruding structure on the two No. 1 pipes respectively. Then, the oil pipe is rotated, thereby causing the slope to rotate between the two protruding structures. Then, the oil pipe is moved to one end, thereby causing the slope at one end to move out from between the protruding structures on the No. 1 pipe, thereby pulling one end of the oil pipe out of the No. 1 pipe. Then, the oil pipe is moved in the reverse direction, thereby pulling the oil pipe out of the No. 1 pipe at the other end, thereby disconnecting both ends of the oil pipe from the No. 1 pipes at both ends respectively, thereby achieving the dismantling of both ends of the oil pipe from the connectors at both ends, thereby completing the dismantling of a single oil pipe when other oil pipes cannot be moved, thereby improving the convenience of dismantling a single oil pipe.
[0027] 4. In this invention, when the driving component moves the sliding component, the sliding component moves the extrusion component, thereby compressing the first bladder-shaped structure, increasing the pressure inside the first bladder-shaped structure, causing the medium inside the first bladder-shaped structure to move through the connecting hole into the second bladder-shaped structure, further increasing the pressure inside the second bladder-shaped structure, causing the sidewall of the second bladder-shaped structure to expand towards the inner wall of the oil pipe, thereby sealing the gap between the first pipe and the inner wall of the oil pipe, thus achieving a reliable seal between the oil pipe and the connecting component; when the extrusion component moves upward, it exerts a force on the pushing structure, causing the sliding component to move towards the driving component, thereby driving the extrusion plate to move towards the pushing structure, thereby reducing the force on the first bladder-shaped structure, causing the medium inside the second bladder-shaped structure to move into the first bladder-shaped structure, thereby reducing the pressure inside the second bladder-shaped structure, and causing the second bladder-shaped structure to deform when the oil pipe is pulled outward, thus facilitating the ramp to slide over the surface of the second bladder-shaped structure, facilitating the pull-out of the oil pipe, and facilitating the removal of the oil pipe.
[0028] 5. In this invention, by setting a first elastic sheet, when the extrusion plate moves towards the driving member along with the sliding member, the first bladder-like structure expands outward under the elastic force of the first elastic sheet, thereby restoring the first bladder-like structure to its original shape, and consequently the second bladder-like structure to its original shape. This separates the outer wall of the second bladder-like structure from the slope before the oil pipe is pulled out, thus avoiding scraping between the slope and the second bladder-like structure when pulling out the oil pipe, facilitating the pulling out of the oil pipe and its removal. Simultaneously, it reduces the probability of damage to the second bladder-like structure due to scraping against the slope, thereby reducing the probability of damage to the second bladder-like structure, and consequently reducing the probability of damage to the first seal, thus ensuring the sealing effect of the first seal and the connection quality of the oil pipe.

Detailed Implementation
[0049] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0050] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17As shown, a stainless steel oil pipe connector for a truck cab tilting system includes a fixing component 1, a connecting pipe 2, a sliding component 3, a driving component 4, and a mounting component 5. The connecting pipe 2 is disposed inside the fixing component 1. The connecting pipe 2 passes through the middle of the fixing component 1. The connecting pipe 2 is connected to the fixing component 1. The two ends of the connecting pipe 2 are symmetrically provided with protruding structures 211. The protruding structures 211 are evenly spaced along the circumference of the connecting pipe 2. The driving component 4 is disposed outside the fixing component 1. The driving component 4 has a cylindrical structure. The driving component 4 is sleeved outside the fixing component 1; the driving component 4 is rotatably connected to the fixing component 1; the driving component 4 has symmetrical mounting components 5 at both ends; the mounting component 5 has a cylindrical structure; one end of the mounting component 5 has a connecting part 51; the connecting parts 51 are evenly spaced along the circumference of the mounting component 5; the fixing component 1 has symmetrical connecting grooves 11 at both ends; the connecting parts 51 are inserted into the connecting grooves 11; the connecting parts 51 are fixedly connected to the fixing component 1; the other end of the mounting component 5 has A sliding groove 52; an extrusion member 6 is provided in the sliding groove 52; the extrusion member 6 is slidably connected to the mounting member 5; the upper end of the extrusion member 6 is provided with an inclined structure 61; the lower end of the extrusion member 6 is provided with an extrusion section 62; the driving member 4 has symmetrical driving structures 41 at both ends; the sliding member 3 is symmetrically arranged at both ends of the driving member 4; the sliding member 3 is a cylindrical structure; one end of the sliding member 3 is sleeved on the driving structure 41; the sliding member 3 is threadedly connected to the driving structure 41; the other end of the sliding member 3... The sliding member 3 is provided with an installation groove 31 at one end; the installation groove 31 is evenly spaced along the circumference of the sliding member 3; the side wall of the installation groove 31 fits against the side wall of the connecting part 51; one end of the sliding member 3 is provided with a pushing structure 32; the pushing structure 32 is evenly spaced along the circumference of the sliding member 3; the pushing structure 32 abuts against the inclined structure 61; a first sealing element 7 is symmetrically provided at both ends of the connecting pipe 2; the first sealing element 7 is a ring structure; the first sealing element 7 is sleeved on the connecting pipe 2.
[0051] During operation, both ends of the connecting pipe 2 are inserted into the two oil pipes to be connected. Then, the driving component 4 is rotated, which in turn drives the driving structures 41 at both ends to rotate, thereby moving the two sliding components 3 (the rotation of the driving structure 41 generates a thrust on the sliding components 3 through the threaded structure, and because the sliding components 3 are slidably connected to the connecting part 51, the sliding components 3 move). This, in turn, drives the pushing structure 32 to move, thereby exerting a force on the inclined structure 61, which in turn moves the extrusion component 6 towards one side of the connecting pipe 2, causing the extrusion component 62 to abut against the side of the oil pipe end, thereby generating a compressive force on the side of the oil pipe end, causing the side to deform towards the protruding structure 211 and form a slope, thus forming several slopes at the end of the oil pipe, with the lower side of the slope abutting against the protruding structure 211, while the upper side of the slope... The pressure section 62 abuts against the oil pipe, thus fixing the position of the slope and connecting the oil pipe and the connector together, thereby connecting the two oil pipes and completing the oil pipe connection. Currently, most stainless steel oil pipes use crimp connections, which require the use of special calipers to compress and deform the oil pipe. Each connection requires two compressions, which is inconvenient for oil pipe connection. Moreover, each caliper can only connect one point at a time. When multiple connections are needed, a lot of waiting time is required, reducing work efficiency. This connector can connect two oil pipes by rotating the drive component 4, thus avoiding the need to use special calipers to connect the oil pipes, thus facilitating the connection of oil pipes. At the same time, it avoids the waiting time of the calipers, thus saving the connection time of the oil pipes and improving the connection efficiency.
[0052] like Figure 11 and Figure 12 As shown, the distance between two adjacent protrusions 211 is greater than the width of the extrusion portion 62.
[0053] By reversing the rotation of the drive component 4, the sliding component 3 moves in the opposite direction, which in turn drives the pushing structure 32 to move in the opposite direction. Under the action of the elastic component below the extruder 6, the extruder 6 moves upward, causing the extrusion part 62 to detach from the slope. Then, the oil pipe to be removed is pushed forcefully, causing the oil pipe to move inward to one side of the connector, thus causing the slope to detach from the protruding structure 211. Then, the oil pipe is rotated, causing the slope to rotate, thus rotating the slope between the two protruding structures 211. Then, the oil pipe is pulled outward, thus pulling the slope out between the two protruding structures 211, thus detaching the oil pipe from the connecting pipe 2, thereby achieving the removal of the oil pipe. Currently, stainless steel oil pipes can only be removed by destructive removal after being crimped, increasing the risk of oil spillage. The difficulty and inconvenience of removing the pipe make it difficult to dismantle the oil pipe. However, this connector can separate the connector and the oil pipe by rotating the drive component 4 in the opposite direction, thus facilitating the removal of the oil pipe and improving the convenience of the connector. When removing the oil pipe by destructive means, it will damage the connector and the oil pipe. The oil pipe must be trimmed, lengthened, and replaced with a new connector before it can be reconnected, which increases the workload of reconnecting the oil pipe. This connector inserts the connecting pipe 2 into the oil pipe, rotates the connecting pipe 2, and then pulls the connecting pipe 2 backward, so that the protruding structure 211 abuts against the slope. Then, the drive component 4 is rotated, so that the extrusion part 62 abuts against the slope, thereby fixing the slope and reconnecting the oil pipe, thus facilitating the reconnection of the oil pipe.
[0054] like Figure 2 , Figure 3 , Figure 9 , Figure 11 and Figure 15As shown, the connecting pipe 2 is a split structure; the connecting pipe 2 includes a first pipe 21; one end of the first pipe 21 is symmetrically provided with a sliding structure 212; the fixing member 1 is symmetrically provided with guide grooves 12; the guide grooves 12 are evenly spaced; the sliding structure 212 is slidably connected in the guide grooves 12; a connecting rod 22 is provided on one of the upper sliding structures 212; one end of the connecting rod 22 is fixedly connected to the sliding structure 212; the other end of the connecting rod 22 is provided with an inclined portion 221; the two ends of the fixing member 1 are symmetrically provided with round holes 13; the connecting rod 22 is slidably connected in the round holes 13; the two ends of the fixing member 1 are... A symmetrical rotating component 14 is provided; the upper end of the rotating component 14 is threadedly connected to the fixed component 1; the lower end of the rotating component 14 is provided with a conical structure; the conical structure abuts against the inclined portion 221; a first elastic component 23 is provided on the connecting rod 22; the first elastic component 23 is sleeved on the connecting rod 22; one end of the first elastic component 23 abuts against the fixed component 1; the other end of the first elastic component 23 abuts against the sliding structure 212; a second sealing component 24 is provided between the two first pipes 21; the second sealing component 24 is a ring structure; both ends of the second sealing component 24 are fixedly connected to the first pipe 21 respectively.
[0055] When a particular oil pipe needs to be dismantled, the drive member 4 on the connectors at both ends of the oil pipe is rotated in the reverse direction, causing the pressing member 6 on the connectors at both ends to disengage from the ramp. Then, the rotating member 14 on the connectors at both ends is rotated, causing the rotating member 14 to move upwards, thereby moving the conical structure upwards. Simultaneously, the drive members 4 at both ends of the oil pipe are pushed, causing the fixing members 1 at both ends to move closer together, thereby causing the two No. 1 pipes 21 to move closer together. This causes the ramps at both ends of the oil pipe to disengage from the protruding structures 211 on the two No. 1 pipes 21. Finally, the oil pipe is rotated, thereby... The ramp rotates between the two protruding structures 211, and then the oil pipe is moved to one end, so that the ramp at one end moves out between the protruding structures 211 on a No. 1 pipe 21, and then one end of the oil pipe is pulled out from the No. 1 pipe 21. Then the oil pipe is moved in the opposite direction, and then the oil pipe is pulled out from the No. 1 pipe 21 at the other end, so that both ends of the oil pipe are disconnected from the No. 1 pipes 21 at both ends, thereby realizing the disconnection of the two ends of the oil pipe from the two ends of the connectors. Thus, the disconnection of a single oil pipe is completed when other oil pipes cannot be moved, thereby improving the convenience of disconnecting a single oil pipe.
[0056] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 18 As shown, a first sealing element 7 is fitted onto the first pipe 21; one end of the first sealing element 7 is provided with a first bladder-like structure 71; the other end of the first sealing element 7 is provided with a second bladder-like structure 72; a connecting structure 73 is provided between the first bladder-like structure 71 and the second bladder-like structure 72; the connecting structures 73 are evenly spaced along the circumference of the first sealing element 7; a connecting hole 731 is provided inside the connecting structure 73; one end of the connecting hole 731 communicates with the inner cavity of the first bladder-like structure 71; the other end of the connecting hole 731 communicates with the inner cavity of the first bladder-like structure 71. The inner cavity of the second bladder-like structure 72 is connected; the sliding member 3 is provided with a compression plate 81; the compression plate 81 is fixedly connected to the sliding member 3; the side of the compression plate 81 is in contact with the side of the first bladder-like structure 71; a limiting member 82 is provided outside the connecting structure 73; the limiting member 82 is sleeved on the connecting structure 73; one end of the limiting member 82 abuts against the compression member 6; the other end of the limiting member 82 abuts against the first bladder-like structure 71; the first bladder-like structure 71 and the second bladder-like structure 72 are filled with an incompressible medium.
[0057] When the driving component 4 moves the sliding component 3, the sliding component 3 moves the extruding component 6, thereby compressing the first bladder structure 71, increasing the pressure inside the first bladder structure 71, and causing the medium inside the first bladder structure 71 to move through the connecting hole 731 into the second bladder structure 72, thereby increasing the pressure inside the second bladder structure 72, and causing the sidewall of the second bladder structure 72 to expand towards the inner wall of the oil pipe, thereby sealing the gap between the first pipe 21 and the inner wall of the oil pipe, thus achieving a reliable seal between the oil pipe and the connecting component; when the extruding component 6 moves upward... The extrusion member 6 exerts a force on the pushing structure 32, which in turn causes the sliding member 3 to move towards the driving member 4, thereby driving the extrusion plate 81 to move towards the pushing structure 32, thereby reducing the force on the first bladder structure 71, thereby causing the medium in the second bladder structure 72 to move into the first bladder structure 71, thereby reducing the pressure in the second bladder structure 72, thereby causing the second bladder structure 72 to deform when the oil pipe is pulled out, thereby facilitating the ramp to slide over the surface of the second bladder structure 72, thereby facilitating the pulling out of the oil pipe, and thus facilitating the removal of the oil pipe.
[0058] like Figure 9 and Figure 10 As shown, the first capsule-shaped structure 71 is provided with a first elastic sheet 711; the first elastic sheet 711 is evenly spaced along the circumference of the first capsule-shaped structure 71; the first elastic sheet 711 is cast together with the side wall of the first capsule-shaped structure 71.
[0059] By setting the first elastic plate 711, when the extrusion plate 81 moves towards the driving member 4 along with the sliding member 3, the first bladder structure 71 expands outward under the elastic force of the first elastic plate 711, thereby restoring the first bladder structure 71 to its original shape, and thus restoring the second bladder structure 72 to its original shape. This separates the outer wall of the second bladder structure 72 from the slope before the oil pipe is pulled out, thus avoiding scraping between the slope and the second bladder structure 72 when the oil pipe is pulled out, making it easier to pull out the oil pipe and facilitate its removal. At the same time, it reduces the probability of the second bladder structure 72 being damaged due to scraping with the slope, thereby reducing the probability of damage to the second bladder structure 72, and thus reducing the probability of damage to the first seal 7, thereby ensuring the sealing effect of the first seal 7 and ensuring the connection quality of the oil pipe.
[0060] like Figure 2 , Figure 4 and Figure 18 As shown, the wall thickness of the second sac-like structure 72 is less than the wall thickness of the first sac-like structure 71.
[0061] The wall thickness of the second bladder structure 72 is less than that of the first bladder structure 71, which makes the second bladder structure 72 easier to deform. This increases the fit between the second bladder structure 72 and the inner wall of the oil pipe, thereby improving the sealing performance between the second bladder structure 72 and the inner wall of the oil pipe, and ultimately improving the connection quality of the oil pipe.
[0062] like Figure 2 and Figure 3 As shown, a second elastic sheet 241 is provided in the inner wall of the second seal 24; the second elastic sheet 241 is evenly spaced along the circumference of the second seal 24; the second elastic sheet 241 is arc-shaped; the second elastic sheet 241 is cast together with the inner wall of the second seal 24; the middle part of the second elastic sheet 241 arches towards the side away from the axis of the second seal 24.
[0063] When the conical structure moves upward, the elastic force of the second elastic piece 241 overcomes the elastic force of the first elastic element 23, thereby causing the first pipe 21 to move into the oil pipe, thereby causing the protruding structure 211 to detach from the lower side of the slope, thus avoiding pushing the oil pipe to separate the slope from the protruding structure 211, thereby directly rotating the oil pipe and pulling it out, thus facilitating the removal of the oil pipe, and thus improving the convenience of the connector.
[0064] like Figure 5 , Figure 6 and Figure 17 As shown, the lower end of the extrusion part 62 is provided with a limiting part 63.
[0065] When inserting the oil pipe into the connector, if the oil pipe is inserted too little, the slope will be reduced, thereby reducing the slope's resistance to deformation, which in turn reduces the connection strength between the oil pipe and the connector, and consequently reduces the connection quality of the oil pipe. If the oil pipe is inserted too long, the slope will be increased, causing the bottom of the slope to abut against the outer wall of pipe 21, which increases the resistance to rotating and pulling out the oil pipe, and consequently reduces the ease of removing the oil pipe. By setting the limiting part 63, the oil pipe is positioned appropriately, ensuring that the size of the slope can guarantee the connection strength while facilitating the removal of the oil pipe, thereby improving the convenience of the connector while ensuring the connection quality.
[0066] like Figure 1 , Figure 2 , Figure 5 , Figure 7 and Figure 9 As shown, the end of the first pipe 21 is provided with an inclined structure 213; the inclined structure 213 is evenly spaced along the circumference of the first pipe 21.
[0067] By setting the inclined structure 213, the sidewall of the second bladder structure 72 is limited, thereby reducing the axial deformation of the second bladder structure 72, increasing the radial deformation of the second bladder structure 72, increasing the extrusion force between the second bladder structure 72 and the inner wall of the oil pipe, thereby improving the sealing performance between the second bladder structure 72 and the inner wall of the oil pipe, thereby improving the sealing performance between the oil pipe and the connector, and thus improving the connection quality of the oil pipe.
[0068] During operation, both ends of the connecting pipe 2 are inserted into the two oil pipes to be connected. Then, the driving component 4 is rotated, which in turn drives the driving structures 41 at both ends to rotate, thereby moving the two sliding components 3 (the rotation of the driving structure 41 generates a thrust on the sliding components 3 through the threaded structure, and because the sliding components 3 are slidably connected to the connecting part 51, the sliding components 3 move). This, in turn, drives the pushing structure 32 to move, thereby exerting a force on the inclined structure 61, which in turn moves the extrusion component 6 towards one side of the connecting pipe 2, causing the extrusion component 62 to abut against the side of the oil pipe end, thereby generating a compressive force on the side of the oil pipe end, causing the side to deform towards the protruding structure 211 and form a slope, thus forming several slopes at the end of the oil pipe, with the lower side of the slope abutting against the protruding structure 211, while the upper side of the slope... The pressure section 62 abuts against the oil pipe, thus fixing the position of the slope and connecting the oil pipe and the connector together, thereby connecting the two oil pipes and completing the oil pipe connection. Currently, most stainless steel oil pipes use crimp connections, which require the use of special calipers to compress and deform the oil pipe. Each connection requires two compressions, which is inconvenient for oil pipe connection. Moreover, each caliper can only connect one point at a time. When multiple connections are needed, a lot of waiting time is required, reducing work efficiency. This connector can connect two oil pipes by rotating the drive component 4, thus avoiding the need to use special calipers to connect the oil pipes, thus facilitating the connection of oil pipes. At the same time, it avoids the waiting time of the calipers, thus saving the connection time of the oil pipes and improving the connection efficiency.
