Description

Technical Field

[0001] This utility model belongs to the field of air conditioning compressor technology, specifically relating to an adjustable air conditioning compressor belt tensioning device. Background Technology

[0002] The working principle of an air conditioner compressor is to compress and drive the refrigerant in the air conditioning refrigerant circuit. It draws the refrigerant from the low-pressure area, compresses it, and sends it to the high-pressure area for cooling and condensation. Then, it dissipates heat into the air through heat exchangers. During this process, the refrigerant changes from a gaseous state to a liquid state, increasing its pressure. As the air conditioner compressor continuously works, it continuously absorbs heat from the low-pressure side into the refrigerant and then sends it to the high-pressure side to dissipate into the air, thus regulating the air temperature.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figure 1-4This utility model provides an adjustable air conditioner compressor belt tensioning device, including a mounting plate 1, an air conditioner compressor 2, a pulley 3, a belt 4, and a crankshaft pulley 5. A fixing bracket 201 is fixedly connected to the air conditioner compressor 2, and the air conditioner compressor 2 is fixedly installed on the top of the mounting plate 1 through the fixing bracket 201. The mounting plate 1 has a mounting hole 101. The pulley 3 is fixedly installed at the front of the air conditioner compressor 2. The crankshaft pulley 5 is connected to the pulley 3 through the belt 4. A matching groove 102 is opened on the mounting plate 1 below the pulley 3. A tensioning mechanism 6 is provided on the mounting plate 1 at the lower part of the belt 4.

[0024] The tensioning mechanism 6 includes a connecting component 61 and a mounting component 62. The connecting component 61 is fixedly installed on the upper part of the mounting plate 1 and located below the belt 4. The mounting component 62 is located on the connecting component 61.

[0025] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the connecting assembly 61 includes an electric telescopic rod 611, which is fixedly installed on the top of the mounting plate 1 and located in front of the matching groove 102. A connecting block 612 is fixedly connected to the right end of the electric telescopic rod 611. A limit frame 613 is slidably provided on the outer side of the connecting block 612 and is connected to the mounting plate 1. A slider 614 is fixedly connected to the rear side of the connecting block 612. The slider 614 has a T-shaped cross-section and is positioned on the mounting plate 1. A matching groove 615 is provided, and the slider 614 is slidably disposed within the groove 615. A mounting groove 618 is provided on the top of the slider 614. A connecting seat 616 is detachably mounted on the upper part of the slider 614 through the mounting groove 618 and the mounting component 62. The connecting seat 616 is Y-shaped. An adjusting wheel 617 is disposed on the upper part of the connecting seat 616. The bottom of the connecting seat 616 is matched with the mounting groove 618. The adjusting wheel 617 is rotatably mounted on the connecting seat 616 and is in contact with the belt 4.

[0026] In use, the electric telescopic rod 611 operates, causing the slider 614 to slide within the groove 615 via the connecting block 612. The limiting frame 613 ensures the stability of the connecting block 612 during its sliding process, thereby ensuring the stability of the slider 614. At this time, the connecting seat 616 drives the adjusting wheel 617 to move, causing the adjusting wheel 617 to compress and deform the belt 4 attached to it. This causes the belt 4 to undergo transmission changes between the pulley 3 and the crankshaft pulley 5 via the adjusting wheel 617, thereby adjusting the tension of the belt 4.

[0027] Further as Figure 2 , Figure 3 and Figure 4As shown, it is worth noting that the mounting component 62 is mounted on the slider 614 for detachable installation of the connecting seat 616 onto the slider 614. The mounting component 62 includes a through-hole 621, which is located on the right side of the slider 614 and communicates with the mounting groove 618. A positioning rod 622 is slidably mounted within the through-hole 621. A matching positioning port 624 is located on the left side of the positioning rod 622, corresponding to the right side of the connecting seat 616. The positioning rod 622 is inserted into the positioning port 624 through the through-hole 621. A limiting plate 623 is fixedly connected to the right side surface of the slider 614. A connecting hole 626 is provided on the limiting plate 623. A pull block 625 is fixedly connected to the right side surface of the limiting plate 623. A bolt 627 is threaded into the connecting hole 626. A matching screw hole 628 is provided on the right side surface of the slider 614 corresponding to the connecting hole 626. The limiting plate 623 is threadedly connected to the right side of the slider 614 through the bolt 627 and the screw hole 628. There are two connecting holes 626 on the limiting plate 623. The two connecting holes 626 are located on the front and rear sides of the pull block 625.

[0028] In use, by tightening the bolt 627, the bolt 627 is dislodged from the screw hole 628, which makes it easy to pull the positioning rod 622 out through the through hole 621 via the pull block 625, releasing the limiting effect with the positioning hole 624. This makes it easier to disassemble the connecting seat 616 from the slider 614, so as to maintain and replace the adjusting wheel 617, thereby improving its service life.

[0029] This solution has the following working process: When this device is in use, the air conditioner compressor 2 is fixedly installed through the mounting hole 101. When it is necessary to adjust the tension of the belt 4, the electric telescopic rod 611 is operated, causing the slider 614 to slide within the slide groove 615 via the connecting block 612. The limiting frame 613 ensures the stability of the connecting block 612 during sliding, thereby ensuring the stability of the slider 614. At this time, the connecting seat 616 drives the adjusting wheel 617 to move, thereby causing the adjusting wheel 617 to compress and deform the belt 4 attached to it. The belt 4 is transmitted between the pulley 3 and the crankshaft pulley 5 via the adjusting wheel 617, thereby adjusting the tension of the belt 4 and adjusting the operation of the air conditioning compressor 2. The adjustment process is simple and easy to implement. By tightening the bolt 627, the bolt 627 is dislodged from the screw hole 628, making it easy to pull the positioning rod 622 out of the through hole 621 through the pull block 625, releasing the limiting effect of the positioning hole 624. This makes it easy to disassemble the connecting seat 616 from the slider 614, so as to maintain and replace the adjusting wheel 617 and thus improve its service life.

[0030] In summary: The tensioning mechanism 6, installed on the upper part of the mounting plate 1, is used to adjust the tension of the belt 4. During the adjustment process, the tension of the belt 4 is adjusted through the connecting component 61. The operation is simple and easy, improving its operability. At the same time, the installation component 62 makes it easy to disassemble and replace the adjusting wheel 617 according to the usage, which facilitates later maintenance and improves its practicality.
