The invention provides a variable frequency air conditioner copper pipe flaring double-joint, which aims to solve the following problems existing in the prior variable frequency air conditioner copper pipe flaring double-joint when in use: (1) the joint and the copper pipe are sealed and fixed through the rubber ring, so that the installation and the disassembly are inconvenient and the sealing performance is poor; (2) the flaring double joint of the variable frequency air conditioner copper pipe has poor self heat dissipation effect, and radial expansion is easily generated after the heat of water in the copper pipe is absorbed, so that adverse effects are caused on the sealing property.
(II) technical scheme
In order to solve the technical problems, the invention adopts the following technical scheme:
the utility model provides a variable frequency air conditioner copper pipe flaring double-joint, includes the connecting pipe, and connecting pipe both ends fixed mounting has two to connect. Circular grooves with coincident axes are formed in the two connectors, and annular grooves with coincident axes are formed in the surfaces of the circular grooves. A plurality of L-shaped grooves are uniformly formed in the joint along the circumferential direction. And a flexible air bag communicated with the L-shaped groove is fixedly arranged in the annular groove. And a sealing column is axially matched in the horizontal section of the L-shaped groove in a sliding manner along the circular groove. And a sliding chute communicated with the L-shaped groove is formed in the joint corresponding to each L-shaped groove. The sliding groove is internally matched with a mounting block fixedly connected with the sealing column in a sliding way. The joint is internally provided with a containing groove corresponding to each sliding groove, and a first spiral spring is fixedly arranged in the containing groove. The end part of the first spiral spring is fixedly connected with the mounting block. The surface of the mounting block close to the axis of the circular groove is fixedly provided with a first magnet block. And the surface of the circular groove is provided with a second magnet block along the axial direction of the circular groove at a position corresponding to each first magnet block. And a supporting block matched with the end face of the copper pipe is fixedly arranged on the second magnet block. The supporting plate is fixedly arranged on the surface of the circular groove, and the elastic telescopic rod arranged along the axial direction of the circular groove is fixedly arranged on the supporting plate. In the process of inserting the copper pipe into the circular groove, the end face of the copper pipe is attached to the supporting block and pushes the supporting block and the second magnet block to slide axially along the circular groove to compress the elastic telescopic rod. The second magnet piece slides in-process and drives first magnet piece, installation piece and seal post synchronous motion through magnetic force, and the first coil spring of installation piece compression. When the elastic telescopic rod is compressed to the shortest state, the mounting block is synchronously attached to the side wall of the sliding groove. The air pressure in the L-shaped groove is reduced in the moving process of the sealing column, and the air in the flexible air bag enters the L-shaped groove, so that the volume of the flexible air bag is reduced. After the volume of the flexible air bag is reduced, the air pressure in the annular groove is reduced, so that the copper pipe is tightly adsorbed on the surface of the circular groove under the action of the air pressure.
The surface of keeping away from the circular slot axis on the installation piece has seted up the slot, and the position that connects inside corresponding every slot offers along the radial first guide way of arranging of circular slot, and sliding fit has the inserted block of mutually supporting with the slot in the first guide way. The outer surface of the joint is provided with a threaded rod which is arranged along the radial direction of the circular groove at the position corresponding to each insert block, and the inner end of the threaded rod is rotationally connected with the insert block. After the installation piece is attached to the side wall of the sliding groove, the threaded rod is rotated to push the insertion block to slide along the first guide groove until the insertion block is inserted into the insertion groove, so that the installation piece and the sealing column are fixed, and the air pressure in the annular groove is guaranteed to be unchanged.
A plurality of cooling grooves are uniformly formed in the connecting pipe along the circumferential direction, and two ports of each cooling groove are located on the outer wall of the connecting pipe. And the outer wall of the connecting pipe is fixedly provided with a cooling pipe corresponding to each cooling groove. The port of the cooling pipe is communicated with the port of the cooling groove. The hot water flows through the connecting pipe and then transfers heat to the connecting pipe, and the cooling tank absorbs the heat on the connecting pipe and then transfers the heat to the cooling water in the cooling pipe. The cooling water in the cooling pipe dissipates heat through the cooling pipe, thereby playing the effect of heat dissipation of the connecting pipe and avoiding the expansion of the connecting pipe due to the rise of temperature after being heated.
As a preferable technical scheme of the invention, a trumpet-shaped annular guide plate is fixedly arranged on the surface of the circular groove. The second magnet block, the supporting plate and the elastic telescopic rod are positioned between the annular guide plate and the surface of the circular groove. The water flow in the copper pipe flows under the action of the annular guide plate after entering the circular groove, so that the water flow is prevented from acting on the second magnet block, the supporting plate and the elastic telescopic rod, and the service life of the second magnet block, the supporting plate and the elastic telescopic rod is prolonged.
As a preferable technical solution of the present invention, a vent groove communicated with the sliding groove is formed on the end surface of the joint close to the connecting pipe at a position corresponding to each sliding groove, so as to prevent the mounting block from being affected by the air pressure in the sliding groove and ensure that the mounting block can slide along the sliding groove.
As a preferred technical scheme of the invention, the outer end of the threaded rod is fixedly provided with a gear column which is coincident with the axis of the threaded rod. The outer surface of the joint is rotatably provided with an installation shaft parallel to the gear columns corresponding to the position of each gear column. The gear plate meshed with the gear column is fixedly arranged on the mounting shaft. The end part of the mounting shaft is fixedly provided with a bevel gear. The outer surface of the joint is rotatably provided with a bevel gear ring which is superposed with the axis of the joint and is meshed with the bevel gear through a connecting rod. The bevel gear, the mounting shaft and the gear disc are driven to rotate by rotating the bevel gear ring. When the gear disc rotates, the gear column and the threaded rod are driven to rotate, so that the insert block is driven to be inserted into the slot. Through the structure, the synchronous movement of all the inserting blocks is realized, and the convenience of operation is improved.
As a preferable technical scheme of the invention, the cooling groove is internally provided with an iron ball which is in sealing fit with the inner wall of the cooling groove in a rolling way. And a third magnet block corresponding to the iron ball in position is in sliding fit with the inner wall of the connecting pipe along the axial direction of the connecting pipe. And a through groove communicated with the cooling groove is formed in the inner wall of the connecting pipe corresponding to each cooling groove. And a fourth magnet block corresponding to the third magnet block in position is arranged in the through groove along the radial direction of the connecting pipe in a sliding fit mode. The surface of the fourth magnet block, which is far away from the axis of the connecting pipe, is fixedly provided with an arc block positioned in the cooling groove. The inside of the connecting pipe is positioned at two sides of the through groove and is provided with a second guide groove. And a sliding sheet in sliding fit with the second guide groove is fixedly arranged on the arc-shaped block. A second spiral spring is fixedly connected between the end part of the second guide groove and the sliding sheet. When water in the copper pipe flows out of the copper pipe and then passes through the connecting pipe, the third magnet block is pushed to slide along the axial direction of the connecting pipe. Attractive force between the iron ball and the third magnet block enables the iron ball to synchronously roll along the cooling groove until the iron ball is attached to the arc block and pushes the arc block to move along the through groove, and the arc block drives the fourth magnet block and the sliding sheet to move in the moving process. The fourth magnet block moves out of the through groove, and the sliding sheet compresses the second spiral spring. And a mutual repulsion force is generated between the fourth magnet block and the third magnet block after the fourth magnet block is moved out of the through groove. The third magnet block slides to the initial position along the axial direction of the connecting pipe in the reverse direction under the action of repulsive force, and simultaneously drives the iron ball to roll back to the initial position along the cooling groove; the slide plate, the fourth magnet block and the arc block are returned to the initial positions by the elastic force of the second coil spring. The third magnet block returning to the initial position performs the actions again under the action of water flow, so that the iron balls roll in the cooling groove in a reciprocating manner; the cooling water in the cooling tank is pushed to the cooling pipe in the process of reciprocating rolling of the iron balls, so that the cooling water in the cooling tank and the cooling pipe is fully exchanged, and the heat dissipation effect is improved.
As a preferable technical scheme of the invention, the third magnet block is hinged with the water baffle through the torsion spring, and when the third magnet block moves towards the fourth magnet block, the water baffle is in a state of being vertical to the axis of the connecting pipe, so that the action effect of water flow on the whole third magnet block and the water baffle is increased. When mutual repulsion force is generated between the third magnet block and the fourth magnet block, mutual repulsion force is also generated between the water baffle and the fourth magnet block, and the water baffle is turned towards one side far away from the fourth magnet block under the action of the mutual repulsion force, so that the blocking effect of water flow in the resetting process of the third magnet block is reduced. After the third magnet block is reset, the water baffle is restored to the initial state under the action of the torsion spring.
(III) advantageous effects
The invention has at least the following beneficial effects:
(1) the invention solves the following problems existing in the prior variable frequency air conditioner copper pipe flaring double-joint when in use: the joint and the copper pipe are sealed and fixed through the rubber ring, so that the installation and the disassembly are inconvenient and the sealing performance is poor; the flaring double joint of the variable frequency air conditioner copper pipe has poor self heat dissipation effect, and radial expansion is easily generated after the heat of water in the copper pipe is absorbed, so that adverse effects are caused on the sealing property.
(2) The flaring double joint of the variable frequency air conditioner copper pipe enables the outer surface of the copper pipe to be tightly adsorbed on the surface of the circular groove by reducing the air pressure in the circular groove; meanwhile, as the air pressure in the annular groove is lower, the liquid in the copper pipe cannot leak through the annular groove, thereby improving the sealing effect. When the joint and the copper pipe are installed, the copper pipe is directly inserted into the joint, and then the bevel gear ring is rotated; when the joint and the copper pipe are disassembled, the copper pipe is pulled out only after the bevel gear ring is rotated, and the operation is convenient.
(3) The flaring double joint of the variable-frequency air conditioner copper pipe absorbs heat from the connecting pipe through cooling water in the cooling groove, transfers the heat to the cooling pipe, and dissipates the heat through the cooling pipe, so that the heat dissipation effect is improved; according to the invention, the iron ball is driven to roll back and forth under the action of water flow in the copper pipe and the mutual repulsion force between the third magnet block and the fourth magnet block, so that cooling water in the cooling tank and the cooling pipe is exchanged, the cooling water absorbing heat in the cooling tank quickly enters the cooling pipe for cooling, and the heat dissipation effect is further improved.

Detailed Description
The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.
As shown in fig. 1 to 6, the present embodiment provides a variable frequency air conditioner copper pipe flaring double joint, which includes a connecting pipe 1, and two joints 2 are fixedly installed at two ends of the connecting pipe 1. Circular grooves 3 with coincident axes are formed in the two connectors 2, and annular grooves 4 with coincident axes are formed in the surfaces of the circular grooves 3. A plurality of L-shaped grooves 5 are uniformly formed in the connector 2 along the circumferential direction. And a flexible air bag 6 communicated with the L-shaped groove 5 is fixedly arranged in the annular groove 4. And a sealing column 7 is axially matched in the horizontal section of the L-shaped groove 5 in a sliding manner along the circular groove 3. The inside position that corresponds every L type groove 5 of joint 2 is seted up the spout 8 that communicates L type groove 5. The sliding groove 8 is internally matched with a mounting block 9 fixedly connected with the sealing column 7 in a sliding way. Connect 2 and offer the air channel 24 of intercommunication spout 8 near the position of every spout 8 on the terminal surface of connecting pipe 1 to avoid installation piece 9 to receive the effect of spout 8 internal gas pressure, ensure that installation piece 9 can slide along spout 8. An accommodating groove 10 is formed in the joint 2 corresponding to the position of each sliding groove 8, and a first spiral spring 11 is fixedly mounted in the accommodating groove 10. The end of the first helical spring 11 is fixedly connected with the mounting block 9. The surface of the mounting block 9 close to the axis of the circular groove 3 is fixedly provided with a first magnet block 12. The second magnet block 13 is mounted on the surface of the circular groove 3 in a manner of sliding along the axial direction of the circular groove 3 at a position corresponding to each first magnet block 12. The second magnet block 13 is fixedly provided with a supporting block 14 matched with the end face of the copper pipe. The surface of the circular groove 3 is fixedly provided with a supporting plate 15, and an elastic telescopic rod 16 which is arranged along the axial direction of the circular groove 3 is fixedly arranged on the supporting plate 15. During the process of inserting the copper pipe into the circular groove 3, the end face of the copper pipe is attached to the supporting block 14 and pushes the supporting block 14 and the second magnet block 13 to slide axially along the circular groove 3 to compress the elastic telescopic rod 16. The second magnet block 13 drives the first magnet block 12, the mounting block 9 and the sealing column 7 to move synchronously through the magnetic force action in the sliding process, and the mounting block 9 compresses the first spiral spring 11. When the elastic telescopic rod 16 is compressed to the shortest state, the mounting block 9 is synchronously attached to the side wall of the sliding chute 8. The air pressure in the L-shaped groove 5 is reduced in the moving process of the sealing column 7, and the air in the flexible air bag 6 enters the L-shaped groove 5, so that the volume of the flexible air bag 6 is reduced. After the volume of the flexible air bag 6 is reduced, the air pressure in the annular groove 4 is reduced, so that the copper pipe is tightly adsorbed on the surface of the circular groove 3 through the action of the air pressure. A horn-shaped annular guide plate 23 is fixedly arranged on the surface of the circular groove 3. The second magnet block 13, the supporting block 14, the supporting plate 15 and the elastic telescopic rod 16 are positioned between the annular flow guide plate 23 and the surface of the circular groove 3. The water flow in the copper pipe flows under the action of the annular guide plate 23 after entering the circular groove 3, so that the water flow is prevented from acting on the second magnet block 13, the supporting block 14, the supporting plate 15 and the elastic telescopic rod 16, and the service lives of the second magnet block 13, the supporting block 14, the supporting plate 15 and the elastic telescopic rod 16 are prolonged.
The surface of keeping away from circular slot 3 axis on the installation piece 9 has seted up slot 17, connects the inside position that corresponds every slot 17 of 2 and has seted up along the radial first guide way 18 that arranges of circular slot 3, and sliding fit has the inserted block 19 of mutually supporting with slot 17 in first guide way 18. A threaded rod 20 which is arranged along the radial direction of the circular groove 3 is arranged on the outer surface of the joint 2 corresponding to the position of each inserting block 19, and the inner end of the threaded rod 20 is rotationally connected with the inserting block 19. After the mounting block 9 is attached to the side wall of the sliding groove 8, the threaded rod 20 is rotated to push the insertion block 19 to slide along the first guide groove 18 until the insertion block 19 is inserted into the insertion groove 17, so that the mounting block 9 and the sealing column 7 are fixed, and the air pressure in the annular groove 4 is guaranteed to be unchanged. The outer end of the threaded rod 20 is fixedly provided with a gear column 25 which is coincident with the axis of the threaded rod. The outer surface of the joint 2 is rotatably mounted with a mounting shaft 26 parallel to the gear post 25 at a position corresponding to each gear post 25. A gear plate 27 is fixedly mounted on the mounting shaft 26 to engage with the gear post 25. The end of the mounting shaft 26 is fixedly mounted with a bevel gear 28. The outer surface of the joint 2 is rotatably provided with a bevel gear ring 29 which is coincident with the axis of the joint and is meshed with the bevel gear 28 through a connecting rod. The bevel gear 28, the mounting shaft 26 and the gear disc 27 are rotated by rotating the bevel gear ring 29. The gear plate 27 rotates to rotate the gear post 25 and the threaded rod 20, thereby driving the insert 19 to be inserted into the slot 17. With the structure, the synchronous movement of all the inserting blocks 19 is realized, and the convenience of operation is improved.
A plurality of cooling grooves 21 are uniformly formed in the connecting pipe 1 along the circumferential direction of the connecting pipe, and two ports of each cooling groove 21 are located on the outer wall of the connecting pipe 1. A cooling pipe 22 is fixedly installed on the outer wall of the connection pipe 1 at a position corresponding to each cooling groove 21. The ports of the cooling pipe 22 and the ports of the cooling groove 21 communicate with each other. The hot water flows through the connection pipe 1 and transfers heat to the connection pipe 1, and the cooling tank 21 absorbs heat on the connection pipe 1 and transfers heat to the cooling water in the cooling pipe 22. The cooling water in the cooling pipe 22 dissipates heat through the cooling pipe 22, thereby achieving the effect of heat dissipation of the connecting pipe 1 and avoiding the expansion of the connecting pipe 1 caused by temperature rise after being heated.
An iron ball 30 which is in sealing fit with the inner wall of the cooling groove 21 is arranged in a rolling way. The inner wall of the connecting pipe 1 is slidably fitted with a third magnet block 31 corresponding to the iron ball 30 in position along the axial direction. The inner wall of the connecting pipe 1 is provided with a through groove communicated with the cooling groove 21 at the position corresponding to each cooling groove 21. A fourth magnet block 32 corresponding to the third magnet block 31 is slidably fitted in the through groove in the radial direction of the connecting pipe 1. The surface of the fourth magnet block 32 away from the axis of the connecting pipe 1 is fixedly provided with an arc-shaped block 33 positioned in the cooling groove 21. The connecting pipe 1 is provided with second guide grooves 34 at two sides of the through groove. A sliding piece 35 which is in sliding fit with the second guide groove 34 is fixedly arranged on the arc-shaped block 33. A second coil spring 36 is fixedly connected between the end of the second guide groove 34 and the slide plate 35. When water in the copper pipe flows out of the copper pipe and then passes through the connecting pipe 1, the third magnet block 31 is pushed to slide along the axial direction of the connecting pipe 1. The attractive force between the iron ball 30 and the third magnet block 31 enables the iron ball 30 to synchronously roll along the cooling groove 21 until the iron ball 30 is attached to the arc block 33 and pushes the arc block 33 to move along the through groove, and the fourth magnet block 32 and the sliding piece 35 are driven to move in the moving process of the arc block 33. The fourth magnet block 32 moves out of the through groove and the slide plate 35 compresses the second coil spring 36. After the fourth magnet block 32 moves out of the through groove, a mutual repulsive force is generated between the fourth magnet block and the third magnet block 31. The third magnet block 31 slides to the initial position along the axial direction of the connecting pipe 1 in the opposite direction under the action of the repulsive force, and simultaneously drives the iron ball 30 to roll back to the initial position along the cooling groove 21; the slide plate 35, the fourth magnet block 32, and the arc block 33 are returned to the initial positions by the elastic force of the second coil spring 36. The third magnet block 31 returned to the initial position performs the above operation again by the water flow, so that the iron ball 30 is reciprocally rolled in the cooling bath 21; the iron balls 30 push the cooling water in the cooling tank 21 to the cooling pipe 22 during the reciprocating rolling process, so that the cooling water in the cooling tank 21 and the cooling pipe 22 is fully exchanged, and the heat dissipation effect is improved. The third magnet 31 is hinged with a water baffle 37 through a torsion spring, and when the third magnet 31 moves towards the fourth magnet 32, the water baffle 37 is in a state of being perpendicular to the axis of the connecting pipe 1, so that the action effect of water flow on the whole third magnet 31 and the water baffle 37 is increased. When mutual repulsion is generated between the third magnet block 31 and the fourth magnet block 32, mutual repulsion is also generated between the water baffle 37 and the fourth magnet block 32, and the water baffle 37 is turned towards one side far away from the fourth magnet block 32 under the action of the mutual repulsion, so that the blocking effect of water flow in the resetting process of the third magnet block 31 is reduced. After the third magnet block 31 is reset, the water guard 37 is restored to the initial state by the torsion spring.
When the copper pipe and the connector 2 are fixed, the copper pipe is only required to be inserted into the circular groove 3, the end face of the copper pipe is attached to the supporting block 14, and the supporting block 14 and the second magnet block 13 are pushed to slide axially along the circular groove 3 to compress the elastic telescopic rod 16. The second magnet block 13 drives the first magnet block 12, the mounting block 9 and the sealing column 7 to move synchronously through the magnetic force action in the sliding process, and the mounting block 9 compresses the first spiral spring 11. When the elastic telescopic rod 16 is compressed to the shortest state, the mounting block 9 is synchronously attached to the side wall of the sliding chute 8. The air pressure in the L-shaped groove 5 is reduced in the moving process of the sealing column 7, and the air in the flexible air bag 6 enters the L-shaped groove 5, so that the volume of the flexible air bag 6 is reduced. After the volume of the flexible air bag 6 is reduced, the air pressure in the annular groove 4 is reduced, so that the copper pipe is tightly adsorbed on the surface of the circular groove 3 through the action of the air pressure. The bevel gear 28, the mounting shaft 26 and the gear disc 27 are rotated by rotating the bevel gear ring 29. The gear plate 27 rotates to drive the gear post 25 and the threaded rod 20 to rotate, so as to drive the insert block 19 to be inserted into the slot 17, thus fixing the mounting block 9 and the sealing post 7 and ensuring that the air pressure in the annular groove 4 is unchanged.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
