Detailed Description
The invention will be further explained with reference to the drawings.
Fig. 1 schematically shows a pipe connector according to an embodiment of the present invention in a state of use. Fig. 2 is a half-sectional view of a pipe connector according to an embodiment of the present invention. As shown in fig. 1 and 2, the pipe connector 100 for connecting a first pipe 200 and a second pipe 300 includes a passage body 1, a sliding inner tube 2, a sealing ferrule 4, an elastic member 3, a sealing washer 5, and a locking mechanism 6. Wherein one end of the passage body 1 is connected to the first pipe member 200, and a first flange 111 and a second flange 121 spaced apart in an axial direction are provided on an inner wall of the passage body 1. The sliding inner cylinder 2 is disposed between the first flange 111 and the second flange 121. The sealing collar 4 is inserted radially between the sliding inner cylinder 2 and the channel body 1. The elastic member 3 is disposed between the second flange 121 and the sliding inner cylinder 2. The sealing gasket 5 is disposed between the first flange 111 and the sliding inner cylinder 2, and is preferably made of an elastic material such as rubber or silicone, and is capable of being elastically deformed when pressed by the second pipe 300, thereby sealing the second pipe 300. The pipe connector 100 further includes a locking mechanism 6 provided on the channel body 1 and used to lock the second pipe 300 to the channel body 1.
When the second tube 300 is inserted into the channel body 1 and pressed against the sealing gasket 5, the second tube 300 can be moved towards the elastic member 3 by pushing the sliding inner cylinder 2 and causing the elastic member 3 to be compressed, so that the locking mechanism 6 can lock the second tube 300 abutting against the sealing gasket 5 and compressing the elastic member 3 on the end of the channel body 1, thereby enabling the first and second tubes 200 and 300 to be communicated together by the channel body 1, the sealing collar 4, the sealing gasket 5 and the sliding inner cylinder 2. Among them, the elastic member 3 is preferably, but not limited to, a compression spring. The sealing collar 4 is preferably, but not limited to, made of an elastic material such as rubber or silicone.
The pipe connector 100 of the embodiment of the present invention is mainly provided with the second flange 121 on the channel main body 1 and the elastic member 3 between the second flange 12112 and the sliding inner cylinder 2. When the elastic member 3 is compressed, it can press the sealing gasket 5 against the end of the second pipe 300 by its own elastic restoring force, thereby enabling the first pipe 200 and the second pipe 300 to be in sealing communication with each other by the passage body 1, the sealing gasket 5, the sealing gasket 4 and the sliding inner cylinder 2. When the second pipe 300 contacts the sealing gasket 5 and the pressure to the sealing gasket 5 is small, the sealing gasket 5 can be pushed by the second pipe 300 to compress the elastic member 3 and ensure the tight engagement of the end of the second pipe 300 with the sealing gasket 5 by the elastic restoring force of the sealing gasket 5. When the second pipe 300 contacts the sealing washer 5 and the pressure on the sealing washer 5 is large, the sealing washer 5 can be pushed by the second pipe 300 to compress the spring, thereby avoiding shortening the service life of the sealing washer 5 due to the excessive deformation of the sealing washer 5. That is, as long as the second tube 300 contacts the sealing gasket 5 and the elastic member 3 is compressed, the elastic member 3 can press the sealing gasket 5 against the end of the second tube 300 by its elastic restoring force regardless of the amount of pressure of the second tube 300 against the sealing gasket 5. The pipe connector of the present invention can prevent the service life of the sealing washer 5 from being shortened due to the excessive pressing force of the second pipe 300 on the sealing washer 5 while ensuring that the second pipe 300 is pressed by the sealing washer 5. Meanwhile, the pipe connector 100 of the present invention has a compact structure, is easy to assemble, is safe and reliable to use, and is convenient to implement, popularize and apply.
In this embodiment, the locking mechanism 6 includes a sliding sleeve 61 fitted over the channel body 1, a compression promoting ring 62 disposed in an end portion of the sliding sleeve 61 away from the channel body 1, an auxiliary compression ring 63 disposed in the channel body 1 and restrained from movement by the first flange 111, an expansion ring sleeve 64 disposed between the compression promoting ring 62 and the auxiliary compression ring 63 and formed by splicing a plurality of segmented pressing pieces 641, and an elastic collar 65 embedded in an inner wall of the expansion ring sleeve 64. Wherein at least one of a first contact surface between the compression-promoting ring 62 and the expansion-collar 64 and a second contact surface between the auxiliary-compression ring 63 and the expansion-collar 64 is a tapered surface. So that the expansion ring sleeve 64 can not only contract radially and clasp the second pipe 300 when the contraction promoting ring 62 moves close to the auxiliary contraction ring 63, but also contract radially when contracting radially, so that the expansion ring sleeve 64 can be expanded radially by the elastic ferrule 65 when the contraction promoting ring 62 moves away from the auxiliary contraction ring 63.
That is to say, when the contraction promotion ring 62 moves close to the auxiliary contraction ring 63, the flap-shaped pressing pieces 641 can perform a converging movement, and the elastic ferrule 65 also radially contracts, so that the second pipe 300 is held tightly by the flap-shaped pressing pieces 641. When the contraction-promoting ring 62 moves away from the auxiliary contraction ring 63, the elastic collar 65 can radially expand by virtue of the elastic restoring force of the elastic collar 65, so that the flap-type pressing blocks 641 perform dispersed movement under the supporting force of the elastic collar 65, and the expansion-contraction collar 64 radially expands. So that the first pipe member 200 and the second pipe member 300 can be commonly communicated by the passage body 1, the sealing gasket 5 and the sliding inner cylinder 2.
When the second contact surface between the auxiliary shrink ring 63 and the expansion ring sleeve 64 is a conical surface, the expansion ring sleeve 64 not only can radially contract and tightly hold the second pipe 300 when the contraction ring 62 moves close to the auxiliary shrink ring 63, but also can slide in the direction close to the sealing washer 5 under the guidance of the second contact surface and drive the second pipe 300 to move in the direction close to the sealing washer 5 after contacting with the second pipe 300, so as to ensure that the second pipe 300 can be pressed on the sealing washer 5, and further avoid fluid leakage caused by the fact that the second pipe 300 is not tightly contacted with the sealing washer 5.
In this embodiment, as shown in fig. 3, in order to achieve the firmness of the locking and the cost, the number of the petal-shaped pressing blocks 641 is preferably three or four, so that not only can the petal-shaped pressing blocks 641 be ensured to perform firm and tight locking on the second pipe 300, but also the excessive increase of the processing cost can be avoided. Preferably, each petal-shaped pressing block 641 is an arc-shaped block, so that a plurality of petal-shaped pressing blocks 641 are spliced into the expansion ring sleeve 64.
In this embodiment, the pipeline connector 100 further includes a rocker assembly 7 provided on the channel body 1 and connected to the sliding sleeve 61, and the rocker assembly 7 can be manipulated to cause the sliding sleeve 61 to slide relative to the channel body 1 and switch between the first and second stations. When the sliding sleeve 61 slides from the first station to the second station, the sliding sleeve 61 can carry the contraction promoting ring 62 to move close to the auxiliary contraction ring 63, so that the flap-type pressing block 641 can perform a gathering motion and clasp the second pipe 300. When the sliding sleeve 61 slides from the second station to the first station, the elastic collar 65 can radially expand by its elastic restoring force, so that the petal press blocks 641 perform a distributed movement under the supporting force of the elastic collar 65, and the expansion and contraction collar 64 radially expands, thereby allowing the second pipe 300 to be inserted between the petal press blocks 641.
In the present embodiment, as shown in fig. 4 and 5, the rocker assembly 7 includes a rocker 71 and a link 72, and the rocker 71 is hinged to the tunnel body 1 by a first hinge shaft 73. One end of the link 72 is hinged to the rocker 71 through a second hinge shaft 711 and the other end thereof is hinged to the slide bush 61 through a third hinge shaft 721. A first hinge shaft 73 provided between the rocker 71 and the tunnel body 1 is eccentrically inserted through a second hinge shaft 711 between the rocker 71 and the link 72. When the rocker 71 is approximately perpendicular to the axis of the channel body 1, the sliding sleeve 61 is in the first station. The operator can push the rocker 71 so that the rocker 71 is approximately parallel to the axis of the passage body 1 and pull the sliding sleeve 61 by means of the link 72 hinged to the rocker 71, so that the sliding sleeve 61 is switched from the first station to the second station. The operator can also turn the rocker 71 so that the rocker 71 is approximately perpendicular to the axis of the passage body 1, pulling the sliding sleeve 61 by means of the link 72 articulated to the rocker 71, switching the sliding sleeve 61 from the second station to the first station. The operator can quickly connect or disconnect the first and second tubulars 200, 300 by pushing the rocker assembly 71 to quickly shift the slide sleeve 61 between the second and first stations.
Preferably, when the sliding sleeve 61 is manipulated to be in the second position, the axes of the first hinge shaft 73, the second hinge shaft 711 and the third hinge shaft 721 are coplanar, the rocker 71 can be forced to stop at the position, so that the sliding sleeve 61 is restrained at the second position, and the flap pressing block 641 can be forced to continuously clasp the second pipe 300, thereby quickly connecting the second pipe 300 to the pipe connector 100.
The connection between the compression ring 62 and the sliding sleeve 61 may be selected as a fixed connection or a threaded connection, but is preferably a threaded connection. When the connection between the collar 62 and the sliding sleeve 61 is a threaded connection, the operator can adjust the pressing force of the flapper press 641 on the second tubular 300 by rotating the collar 62 to move the collar 62 closer to or away from the auxiliary collar 63. When the pipe diameter of the second pipe 300 is small, the operator can rotate the contraction promoting ring 62 to make the contraction promoting ring 62 move close to the auxiliary contraction ring 63, and the expansion ring sleeve 64 contracts radially and holds the second pipe 300 tightly. When the pipe diameter of the second pipe 300 is larger, the operator can rotate the contraction promoting ring 62 to make the contraction promoting ring 62 move away from the auxiliary contraction ring 63, and the expansion ring sleeve 64 expands radially to just hold the second pipe 300 tightly. Thus, the operator can tighten the second pipe 300 of a different pipe diameter by rotating the contraction promotion ring 62. Preferably, the line connector 100 further comprises an operating portion provided on an end of the compression promotion ring 62 remote from the sliding sleeve 61, the operating portion being prism-shaped so as to facilitate an operator to rotate the compression promotion ring 62 by screwing the prism-shaped end of the compression promotion ring 62.
In this embodiment, the pipeline connector 100 includes a locking nut 8 disposed on the outer wall of the compression collar 62, the connection between the locking nut 8 and the compression collar 62 is a threaded connection, when the operator rotates the compression collar 62 to make the expansion collar 64 just hug the second pipe 300, the locking nut 8 can be adjusted by rotation to make the locking nut 8 abut against the sliding sleeve 61, so as to fix the relative position between the compression collar 62 and the sliding sleeve 61 and ensure that the flap-type pressing block 641 is pressed on the second pipe 300 continuously.
In this embodiment, the tube connector 100 further includes a resilient member 9 disposed between the first flange 111 and the secondary collar 63 and capable of radially expanding and contracting. When the pipe diameter of the second pipe 300 is large, when the sliding sleeve 61 is at the second station and the flap-type pressing block 641 tightly holds the second pipe 300, the auxiliary compression ring 63 can be stressed by a reaction force to compress the elastic component 9, so that the elastic component 9 is elastically deformed in the axial direction, the axial distance between the auxiliary compression ring 63 and the contraction promoting ring 62 is adjusted, the inner diameter of the expansion ring sleeve 64 is adjusted by matching with the elastic ferrule 65, the flap-type pressing block 641 can be tightly held on the second pipe 300, and the risk that the second pipe 300 is crushed by the flap-type pressing block 641 is reduced. Preferably, the elastic assembly 9 comprises a first cushion washer 91, a transmission washer 92 and a second cushion washer 93, which are arranged in sequence from the secondary collar 63 towards the first flange 111. The first cushion ring 91 and the second cushion ring 93 are preferably elastic rings, such as elastic sealing rings made of rubber or silicone. The first cushion washer 91 and the second cushion washer 93 can secure a sufficient deformation distance of the elastic assembly 9. The drive washer 92 is preferably a hard washer, such as a copper washer or a stainless steel washer, to reduce the risk of buckling of the elastomeric assembly 9. The first cushion washer 91 and the second cushion washer 93 are preferably elastic sealing rings having circular radial cross sections, and the contact area between the first cushion washer 91 and the second cushion washer 93 and the second pipe 300 can be reduced, so that the friction force applied to the second pipe 300 during the insertion process can be reduced.
In the present embodiment, the channel body 1 can be an integral type or a split type. When the channel body 1 is chosen to be split, the channel body 1 comprises a first part 11 and a second part 12. The sliding inner cylinder 2, the sealing collar 4, the sealing washer 5 and the locking mechanism 6 are all arranged in a first part 11. The first flange 111 is provided on the first member 11, the second flange 121 is provided on the second member 12, and the elastic member 3 is provided between the second flange 121 and the sliding inner tube 2. This can facilitate the sliding inner cylinder 2, the sealing ferrule 4, the elastic member 3, and the sealing gasket 5 to be put into the channel body 1, contributing to simplification of the manufacturing process of the pipe connector 100. The connection between the first component 11 and the second component 12 is preferably a strong and reliable screw connection.
Next, the method of use of the line connector 100 will be described, first, the second tube 300 is inserted into the channel body 1, the end of the second tube 300 is pressed against the sealing washer 5, the rocker 71 is pushed so that the rocker 71 is approximately parallel to the channel body 1, and the sliding sleeve 61 is switched from the first position to the second position. In the process, the sliding sleeve 61 can carry the contraction promoting ring 62 to move close to the auxiliary contraction ring 63, so that the expansion ring sleeve 64 holds the second pipe 300 tightly and drives the second pipe 300 to move towards the direction close to the sealing washer 5 after contacting, thereby ensuring that the second pipe 300 can be locked and pressed on the sealing washer 5 quickly.
Then, the contraction-promoting ring 62 is rotated according to the pipe diameter of the second pipe 300, when the sliding sleeve 61 is in the second station and the pipe diameter of the second pipe 300 is larger than the inner diameter of the expansion-contraction ring 64, the contraction-promoting ring 62 is rotated to make the contraction-promoting ring 62 move away from the auxiliary contraction ring 63, the elastic collar 65 can radially expand by virtue of the elastic restoring force of the elastic collar 65, so that the flap-type pressing block 641 dispersedly moves under the supporting force of the elastic collar 65, and the expansion-contraction ring 64 radially expands to just clamp the second pipe 300. When the sliding sleeve 61 is at the second station and the pipe diameter of the second pipe 300 is smaller than the inner diameter of the expansion ring sleeve 64, the operator can rotate the contraction promoting ring 62 to make the contraction promoting ring 62 move close to the auxiliary contraction ring 63, the flap type pressing block 641 makes a gathering motion, and the expansion ring sleeve 64 contracts radially, so as to be just tightly embraced on the second pipe 300.
Then, the locking nut 8 is rotated to make the locking nut 8 abut against the sliding sleeve 61, and the relative position between the compression-promoting ring 62 and the sliding sleeve 61 is fixed, so that the first pipe fitting 200 and the second pipe fitting 300 can be communicated together by the passage body 1, the sealing washer 5 and the sliding inner cylinder 2.
Finally, the rocker 71 is rotated to drive the sliding sleeve 61 to switch from the second station to the first station through the connecting rod 72, the elastic collar 65 can radially expand by virtue of the elastic restoring force of the elastic collar 65, so that the petal-shaped pressing block 641 performs a distributed motion under the supporting force of the elastic collar 65, the expansion and contraction collar 64 performs a radial expansion and drives the second pipe 300 to perform a motion away from the sealing washer 5 before disengaging from the second pipe 300, thereby allowing the second pipe 300 to be rapidly taken out of the channel body 1.
In summary, the pipe connector 100 according to the embodiment of the present invention solves the problem in the prior art that the service life of the sealing gasket 5 is shortened due to the excessive pressure of the second pipe 300 on the sealing gasket 5, so that the service life of the sealing gasket 5 is prevented from being shortened due to the excessive pressure of the second pipe on the sealing gasket 5 while the second pipe is sealed by the sealing gasket 5.
