Description

Technical Field

[0001] This application relates to the field of air conditioning copper pipe connection technology, and in particular to an air conditioning copper pipe connection fastening structure. Background Technology

[0002] Air conditioning piping systems include copper pipes, also known as copper tubes, which are a type of non-ferrous metal pipe. They are seamless pipes that are pressed and drawn. Copper pipes have good electrical and thermal conductivity, making them a primary material for conductive and heat dissipation components in electronic products. They are also the first choice for air conditioning piping systems, and are mostly used for connecting the outdoor and indoor units of air conditioners.

[0003] A search revealed a patent document with authorization announcement number CN219454214U, which discloses a copper pipe connection and fastening structure for air conditioners. The structure includes an air conditioner side panel, a lower fixing plate fixedly mounted on the side of the side panel, an upper fixing plate inserted into the top of the lower fixing plate, and a locking bolt securing the connection between the upper and lower fixing plates. A clamping plate is installed inside the lower fixing plate, and a retaining plate is installed inside the clamping plate. A threaded rod is connected to the bottom of the retaining plate. This copper pipe connection and fastening structure uses an insert connection between the upper and lower fixing plates, secured with locking bolts. The copper pipe, already connected to the indoor unit of the air conditioner, is initially fixed by the upper fixing plate when placed on the lower fixing plate. After initial fixation, rotating the threaded rod pushes the clamping plate upwards until it presses against the copper pipe, providing a secondary fixation. This simple structure, requiring only tightening the locking bolts and threaded rod to secure the copper pipe, facilitates easy assembly and disassembly and provides good connection stability.

[0004] In practical use, it has been found that after installation, the bolts of existing air conditioning copper pipes may loosen slightly due to long-term use of the air conditioner, which can cause the copper pipes to wobble and affect the stable operation of the air conditioning system. Therefore, we have proposed an air conditioning copper pipe connection and fastening structure to solve the above problems. Utility Model Content

[0030] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] See Figures 1-4 This application provides an air conditioner copper pipe connection and fastening structure, including an air conditioner side plate 1, a connecting seat 2 fixedly installed on the right side of the air conditioner side plate 1, and mounting holes 201 opened on both the air conditioner side plate 1 and the connecting seat 2. An air conditioner copper pipe 3 is inserted into the mounting holes 201, and a connecting plate 301 is fixedly sleeved on the outside of the air conditioner copper pipe 3. A fixing mechanism is provided between the connecting plate 301 and the connecting seat 2. Two cavities 5 are opened in the connecting seat 2, and the two cavities 5 are located on the upper and lower sides of the mounting holes 201 respectively. A limit mechanism is provided in the cavity 5, a reset mechanism is provided in the cavity 5, and a sealing gasket is provided on the inner wall of the mounting hole 201. The sealing gasket is adapted to the air conditioner copper pipe 3.

[0032] Specifically, the fixing mechanism includes bolt 4, screw hole 401 and threaded groove 402. The connecting plate 301 has screw hole 401, and the connecting seat 2 has threaded groove 402 on the right side. Bolt 4 is installed in the screw hole 401 and threaded groove 402.

[0033] Specifically, the limiting mechanism includes a lead screw 501, a lead screw seat 502, and a limiting post 503. The same lead screw 501 is rotatably installed on the top inner wall and the bottom inner wall of the cavity 5. The lead screw seat 502 is threaded onto the lead screw 501. The right side of the lead screw seat 502 is slidably connected to the right inner wall of the cavity 5. The limiting post 503 is fixedly installed on the side of the lead screw seat 502 near the mounting hole 201. The other end of the limiting post 503 extends into the mounting hole 201.

[0034] Specifically, the top and bottom of the air conditioning copper pipe 3 are provided with limiting grooves 504, and the limiting post 503 is engaged with the corresponding limiting groove 504.

[0035] Specifically, the reset mechanism includes a slide plate 6 and a spring 603. The slide plate 6 is slidably installed on the inner wall of the cavity away from the mounting hole 201. The same spring 603 is fixedly installed on the slide plate 6 and the left inner wall of the cavity 5. A gear mechanism is provided between the slide plate 6 and the lead screw 501.

[0036] Specifically, the gear mechanism includes a rack plate 601 and a gear 602. The rack plate 601 is fixedly installed on the right side of the slide plate 6, and the gear 602 is fixedly sleeved on the lead screw 501. The gear 602 is located outside the lead screw seat 502, and the rack plate 601 and the gear 602 mesh with each other.

[0037] Specifically, the right end of the rack plate 601 extends into the threaded groove 402, and a push plate 7 is fixedly installed on the right end of the rack plate 601. The left end of the bolt 4 is adapted to the right side of the push plate 7.

[0038] Specifically, the threaded groove 402 and the cavity 5 are provided with the same through hole, and the rack plate 601 is slidably connected to the inner wall of the back side of the through hole.

[0039] In this application, when installing the air conditioner copper pipe, the air conditioner copper pipe 3 is first accurately inserted into the mounting hole 201 that is opened together by the air conditioner side plate 1 and the connecting seat 2; this ensures that the copper pipe is in the correct installation position; then, the bolt 4 is used to screw it into the screw hole 401 that is pre-opened in the connecting plate 301 and the threaded groove 402 on the right side of the connecting seat 2, so that the connecting plate 301 and the connecting seat 2 can fit tightly together, thereby fixing the air conditioner copper pipe 3.

[0040] As bolt 4 is continuously screwed in, its left end gradually approaches and eventually pushes push plate 7. Push plate 7 is fixedly connected to rack plate 601, so the movement of push plate 7 drives rack plate 601 to move synchronously to the left. Rack plate 601 meshes with gear 602 fixedly sleeved on lead screw 501. When rack plate 601 moves, according to the transmission principle of gear and rack, gear 602 starts to rotate, thereby driving lead screw 501 to rotate together. Lead screw 501 is threaded with lead screw seat 502, and the right side of lead screw seat 502 is slidably connected to the right inner wall of cavity 5. This structural design restricts the movement of lead screw seat 502, making it only able to move along lead screw 501. 1. Axial movement; When the lead screw 501 rotates, the lead screw seat 502 will move towards the air conditioning copper pipe 3 in the mounting hole 201 under the action of the thread; A limiting post 503 is fixedly installed on the side of the lead screw seat 502 near the mounting hole 201. As the lead screw seat 502 moves, the limiting post 503 also moves closer to the air conditioning copper pipe 3 until the limiting post 503 is accurately inserted into the limiting groove 504 pre-opened at the top and bottom of the air conditioning copper pipe 3; This can further stabilize the position of the air conditioning copper pipe 3 and prevent it from shaking or shifting due to slight loosening of the bolt 4 during use, thereby ensuring the stability of the air conditioning system operation;

[0041] When it is necessary to disassemble the air conditioning copper pipe, the operation process is the reverse of the installation process. By unscrewing the bolt 4 in the reverse direction, the left end of the bolt 4 gradually separates from the push plate 7. At this time, the spring 603, which was originally in a compressed state, begins to play its role. One end of the spring 603 is fixed to the inner wall of the left side of the cavity 5, and the other end is connected to the slide plate 6, which is in turn fixedly connected to the rack plate 601. Under the elastic force of the spring 603, the slide plate 6 drives the rack plate 601 to move to the right. The movement of the rack plate 601, through the gear and rack transmission relationship, drives the gear 602 to rotate in the opposite direction, thereby causing the lead screw 501 to reverse. As the lead screw 501 reverses, the lead screw seat 502 moves away from the air conditioning copper pipe 3 along the axial direction of the lead screw 501, thereby driving the limiting post 503 to leave the limiting groove 504 of the air conditioning copper pipe 3. At this time, the limiting of the air conditioning copper pipe 3 is released, making it easy to remove it from the mounting hole 201 and complete the disassembly operation.
