[0002] In the current air conditioner liquid storage device, the cylinder is made of steel pipe, and the air inlet and outlet pipes are made of copper pipes. The air inlet and outlet pipes are generally connected to the cylinder by brazing. Because brazing is a method of using a metal material with a liquid phase temperature (melting point) higher than the solid phase temperature of the base material as a brazing material, heating the parts and the brazing material until the brazing material melts, and using the liquid brazing material to wet the base material, fill the joint gap, and dissolve and diffuse with the base material to achieve the connection of parts.

[0003] In the compressor used in existing air conditioners, when welding the steel pipe on the liquid accumulator that is responsible for the flow of refrigerant, the worker usually holds the steel pipe with one hand and welds the steel pipe and the connecting pipe with a welding gun with the other hand.

[0038] A first spring is connected between adjacent slide plates.

[0039] The present invention also provides a method for using a steel pipe structure for an air conditioner liquid storage device, comprising the following specific steps:

[0040] Step 1: First, push one of the handles to make one of the slides slide inside the cavity and drive the block connected thereto to slide horizontally, and then put the insertion ring on the outside of the steel pipe so that the insertion column and the insertion ring are inserted, then release the handle, and push the slide to slide horizontally through the elastic support of the first spring, so that the block and the insertion column are inserted and connected, so as to realize the installation positioning between the insertion column and the insertion ring, and at this time, the insertion ring and the steel pipe are in a concentric state;

[0041] Step 2: Secondly, under the limit of the ear plate, the sliding support rod slides vertically relative to the steel pipe, so that the rotation positioning mechanism is sleeved on the outside of the connecting pipe;

[0042] Step 3: Then rotate the rotating ring so that the rotating ring rotates outside the collar. Since the sliding column and the inner cavity of the eccentric arc groove are slidably interlaced and connected, when the rotating ring is rotated, the eccentric arc groove will be driven to rotate synchronously. Due to the eccentric setting of the eccentric arc groove, the rotation of the rotating ring causes the inner side wall of the eccentric arc groove to push the sliding column, so that the sliding column slides centripetally toward the direction of the connecting pipe under the limit of the straight through slot. Since the collar and the steel pipe are concentrically set, when multiple groups of positioning columns synchronously self-center the connecting pipe, the relative position between the connecting pipe and the steel pipe can be adjusted, so that the connecting pipe and the steel pipe can be concentric and coaxial.

[0043] Step 4: When the rotating ring is rotated, the one-way locking assembly will be driven to rotate synchronously. When rotating clockwise, the inclined surface of the locking tooth and the inclined surface of the one-way tooth cooperate with each other. The cooperation between the inclined surfaces will not affect the normal clockwise rotation of the rotating ring. The elastic support of the locking tooth by the second spring can ensure the one-way locking of the locking tooth and the one-way tooth to prevent the rotating ring from rotating counterclockwise, so as to ensure the stable clamping of the connecting tube by the positioning column.

[0044] Technical effects and advantages of the present invention:

[0045] (1) The present invention utilizes a setting method in which the collar and the positioning column cooperate with each other. Through the eccentric setting of the eccentric arc groove, the rotation of the rotating ring causes the inner side wall of the eccentric arc groove to push the sliding column. Since the collar and the steel pipe are concentrically arranged, when multiple groups of positioning columns synchronously self-center the connecting pipe, the relative position between the connecting pipe and the steel pipe can be adjusted, so that the connecting pipe and the steel pipe can be concentric and coaxial. When the steel pipe is adjusted to be concentric and coaxial with the connecting pipe, the worker does not need to manually support the steel pipe. The worker only needs to make a few welding points between the connecting pipe and the steel pipe, thereby ensuring the welding accuracy between the connecting pipe and the steel pipe and preventing the connection pipe from being offset during welding.

[0046] (2) The present invention utilizes a configuration in which a toothed limiting assembly and a one-way locking assembly cooperate with each other. The toothed limiting assembly can limit the one-way locking assembly in one direction, so that when the rotating ring rotates clockwise, the positioning column extends to abut against the connecting pipe, thereby preventing the rotating ring from reversing, thereby preventing the positioning column from retracting, and making the positioning column abutting against the connecting pipe more stable;

[0047] (3) The present invention utilizes a setting mode in which the locking teeth and the pressing block cooperate with each other, and through the sliding interlacing between the pressing block and the limiting cylinder, when it is necessary to disassemble the rotation positioning mechanism outside the connecting tube, the pressing block is pushed inwardly, so that the pressing block moves in the direction of the locking teeth, thereby driving the end of the connecting rope to perform a linear translation motion, and through the fixed pulley limiting the routing of the connecting rope, the other end of the connecting rope can be pulled to move, so as to drive the movement of the locking teeth, so that the locking teeth perform a sliding retracting motion in the direction of the second spring, and no longer maintain the unidirectional locking position with the one-way teeth, so that the rotating ring can be rotated counterclockwise to drive the positioning column, so that the positioning column is retracted and stored in the inside of the sleeve, so that the rotation positioning mechanism can slide out of the outside of the connecting tube, so as to facilitate the subsequent all-round welding between the connecting tube and the steel tube, and through the compression deformation of the second spring, the elastic support of the locking teeth is facilitated, so that the locking position between the locking teeth and the one-way teeth is more stable, and it is also convenient to support and reset the locking teeth.

[0069] Method of use of the present invention:

[0070] First, push one of the handles to make one of the slide plates 4141 slide inside the cavity and drive the block 4142 connected thereto to slide horizontally, and then put the insertion ring 412 on the outside of the steel pipe 3, so that the insertion column 411 and the insertion ring 412 are inserted, and then release the handle, and push the slide plate 4141 to slide horizontally through the elastic support of the first spring 4143, so that the block 4142 and the insertion column 411 are inserted and connected, so as to realize the installation and positioning between the insertion column 411 and the insertion ring 412, and at this time, the insertion ring 412 and the steel pipe 3 are in a concentric state;

Since the sliding post 424 is slidably connected with the inner cavity of the eccentric arc groove 4212, when the rotating ring 422 is rotated, the synchronous rotation of the eccentric arc groove 4212 is driven. Due to the eccentric setting of the eccentric arc groove 4212, the rotation of the rotating ring 422 causes the inner side wall of the eccentric arc groove 4212 to push the sliding post 424, so that the sliding post 424 slides centripetally toward the direction of the connecting pipe 2 under the limitation of the straight through slot 4211. Since the ring 421 and the steel pipe 3 are concentrically set, when the multiple groups of positioning posts 423 synchronously self-center the connecting pipe 2, the relative position between the connecting pipe 2 and the steel pipe 3 can be adjusted, so that the connecting pipe 2 and the steel pipe 3 can be concentric and coaxial.

[0073] When the rotating ring 422 is rotated, the one-way locking assembly 426 will be driven to rotate synchronously. When rotating clockwise, the inclined surface of the locking tooth 4261 cooperates with the inclined surface of the one-way tooth 4252. Through the cooperation between the inclined surfaces, the normal clockwise rotation of the rotating ring 422 is not affected. The elastic support of the locking tooth 4261 by the second spring 4262 can ensure the one-way locking connection between the locking tooth 4261 and the one-way tooth 4252, so as to prevent the rotating ring 422 from rotating counterclockwise, so as to ensure the stable clamping of the positioning column 423 to the connecting tube 2.

10. A method for using a steel pipe structure for an air conditioner liquid storage tank according to any one of claims 1 to 9, characterized in that: The specific usage steps are as follows: Step 1: First, push one of the handles so that one of the slide plates (4141) slides inside the cavity and drives the block (4142) connected thereto to slide horizontally, and then sleeve the insertion ring (412) on the outside of the steel pipe (3) so that the insertion column (411) and the insertion ring (412) are inserted, then release the handle, and push the slide plate (4141) to slide horizontally through the elastic support of the first spring (4143), so that the block (4142) and the insertion column (411) are inserted and connected, so as to realize the installation positioning between the insertion column (411) and the insertion ring (412), and at this time, the insertion ring (412) and the steel pipe (3) are in a concentric state; Step 2: Next, under the limit of the ear plate, the sliding support rod (413) is made to slide vertically relative to the steel pipe (3), so that the rotation positioning mechanism (42) is sleeved on the outside of the connecting pipe (2); Step 3: Then rotate the rotating ring (422) so that the rotating ring (422) rotates outside the collar (421). Since the sliding column (424) is slidably interlaced with the inner cavity of the eccentric arc groove (4212), when the rotating ring (422) is rotated, the eccentric arc groove (4212) is driven to rotate synchronously. Due to the eccentric setting of the eccentric arc groove (4212), the rotation of the rotating ring (422) causes the eccentric arc groove (4212) to rotate synchronously. The inner wall pushes the slide post (424), so that the slide post (424) slides centripetally in the direction of the connecting pipe (2) under the limit of the straight through slot (4211). Since the collar (421) and the steel pipe (3) are concentrically arranged, when the multiple groups of positioning posts (423) synchronously self-center the connecting pipe (2), the relative position between the connecting pipe (2) and the steel pipe (3) can be adjusted, so that the connecting pipe (2) and the steel pipe (3) can be concentric and coaxial. Step 4: When the rotating ring (422) is rotated, the one-way locking assembly (426) will be driven to rotate synchronously. When rotating clockwise, the inclined surface of the locking tooth (4261) cooperates with the inclined surface of the one-way tooth (4252). The cooperation between the inclined surfaces will not affect the normal clockwise rotation of the rotating ring (422). The elastic support of the locking tooth (4261) by the second spring (4262) can ensure the one-way locking of the locking tooth (4261) and the one-way tooth (4252) to prevent the rotating ring (422) from rotating counterclockwise, so as to ensure the stable clamping of the positioning column (423) to the connecting tube (2).
