Technical Field

[0001] The utility model belongs to the technical field of air compressors, and in particular relates to a direct-connected screw air compressor. Background Art

[0002] An air compressor is a device used to compress gas. An air compressor is similar in structure to a water pump. Most air compressors are reciprocating piston, rotary vane or rotary screw. Screw air compressors are pre-packaged and require only a single power connection and compressed air connection, and have a built-in cooling system, which greatly simplifies installation.

[0003] Existing air compressors are usually installed by bolts. When the air compressor is in use, the air compressor will vibrate, and the vibration will cause the bolts to loosen, resulting in instability during installation of the air compressor, which affects the use effect of the air compressor. Therefore, we propose a direct-connected screw air compressor. Utility Model Content

[0004] The purpose of the utility model is to provide a direct-connected screw air compressor to solve the problems raised in the above-mentioned background technology.

[0005] In view of this, the utility model provides a direct-connected screw air compressor, comprising:

[0006] A box body, the top surface of which is provided with a fixing plate, the top surface of which is fixedly mounted with a direct-connected screw air compressor body;

[0007] A plurality of ferrules, wherein the ferrules are fixedly mounted on the peripheral side of the fixed plate, and a plurality of movable plates are slidably mounted on the top surface of the box body, and a plurality of card blocks are fixedly mounted on one side of the plurality of movable plates, and the plurality of card blocks are movably sleeved with the plurality of movable plates;

[0009] A threaded rod, the threaded rod is rotatably mounted in the box, a threaded sleeve is threadedly connected to the threaded rod, a plurality of movable seats are fixedly mounted on the circumference of the threaded sleeve, a connecting rod is rotatably mounted in each of the plurality of movable seats, and the top ends of the plurality of connecting rods are rotatably mounted in the plurality of movable seats respectively;

[0010] An adjusting component is arranged on the box body and is used to drive the threaded rod to rotate.

[0011] In the above technical solution, further, the adjustment component includes a movable shaft, which rotates in the box body, and the top end of the movable shaft passes through the inner wall of the box body and extends to the outside of the box body. The outer wall of the movable shaft and the outer wall of the threaded rod are both fixedly installed with pulleys, and the same belt is provided on the two pulleys.

[0012] In the above technical solution, further, a fixed plate is fixedly installed on the outer wall of the movable shaft, a plurality of first limiting holes are opened on the fixed plate, and a plurality of second limiting holes are opened on the top surface of the box body, and the same pin is movably sleeved in one of the first limiting holes and one of the second limiting holes.

[0013] In the above technical solution, further, a plurality of mounting plates are fixedly mounted on both sides of the box body, and mounting holes are formed on the plurality of mounting plates.

[0015] In the above technical solution, further, an adjustment handle is fixedly mounted on the top end of the movable shaft.

[0016] The beneficial effects of the utility model are:

[0017] 1. For the direct-coupled screw air compressor, when disassembling the body of the direct-coupled screw air compressor, it is only necessary to take out the pin from the first limiting hole and the second limiting hole to release the limiting of the movable shaft, and turn the adjusting handle to drive the movable shaft to rotate. When the movable shaft rotates, the cooperation of the two pulleys and the belt will drive the threaded rod to rotate, and when the threaded rod rotates, the threaded sleeve will move on the threaded rod, and when the threaded sleeve moves, the cooperation of the movable seat and the connecting rod will drive the movable seat to move, and when the movable seat moves, the movable plate will be driven to move through the slider, and after the movable plate moves to a certain position, the block will be disengaged from the sleeve, and at this time, the limiting of the fixed plate will be released, so that the body of the direct-coupled screw air compressor can be disassembled.

[0018] 2. When installing the direct-connected screw air compressor body, place the fixing plate on the top surface of the box body. The fixing plate can be initially positioned and installed through the positioning column and the positioning hole. After the fixing plate is placed on the box body, turn the adjustment handle to drive the movable shaft to rotate. The threaded rod will be driven to rotate through the cooperation of the two pulleys and the belt. When the threaded rod rotates, the threaded sleeve will move downward on the threaded rod. When the threaded rod moves, the slider will be driven to move through the cooperation of the movable seat, the movable seat and the connecting rod. The slider drives the movable plate to move so that the card block is sleeved in the corresponding card sleeve. At this time, the position of the fixed plate will be limited, thereby realizing the installation of the direct-coupled screw air compressor body. After the direct-coupled screw air compressor body is installed, the pin is sleeved in the corresponding second limiting hole and the first limiting hole. At this time, the movable shaft will be limited. When the movable shaft is limited, the threaded rod can be limited. After the threaded rod is limited, multiple movable plates will be limited, thereby enhancing the fixity and stability of the direct-coupled screw air compressor body during installation.
