Description
Technical Field
[0001] The utility model relates to the technical field of compressor casing structures, in particular to a compressor casing structure. Background Art
[0002] The compressor is a driven fluid machine that boosts low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It sucks low-temperature and low-pressure refrigerant gas from the intake pipe, compresses it by driving the piston through the motor, and then discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle.
[0003] The compressor shell plate and the end cover are usually connected by bolts. When the compressor is used for a long time, it is affected by vibration, and the screws will become loose individually, resulting in uneven tightening force of the end cover screws, which can easily cause air leakage on the sealing surface between the end cover and the cylinder. At the same time, stains and dust will adhere to the outside of the bolts when they are wet, blocking the knob end of the screws and affecting the tightening operation of the screws. Therefore, a compressor casing structure is needed to solve the above problems. Utility Model Content
[0004] The purpose of the utility model is to solve the problems raised in the above background technology.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A compressor casing structure includes a compressor shell barrel, four screw barrel ends are arranged on the right side of the compressor shell barrel, a cover group is connected to the right side of the compressor shell barrel through a locking assembly, the cover group includes an end cover, the locking assembly includes an external plate, the external plate is fixed to the four sides of the end cover, a threaded plug shaft is connected to the left side of the external plate, the threaded plug shaft passes through the interior of the screw barrel end of the compressor shell barrel through a through hole, two nuts are threadedly sleeved on the end of the threaded plug shaft, and a limiting assembly is arranged on the outside of the screw barrel end of the compressor shell barrel.
[0007] Preferably, an inner connecting ring is connected to the inner side of the end cover, and a rubber ring gasket is installed on the outer side of the inner connecting ring through a ring groove. The rubber ring gasket is deformed under force to fill the gap between the end cover and the compressor shell, thereby ensuring the sealing performance of the docking between the end cover and the compressor shell.
[0008] Preferably, two positioning blocks are symmetrically connected to the inner wall of the end cover, and the positioning blocks are inserted into the interior of the compressor shell through positioning grooves. The positioning blocks are inserted into the slots of the compressor shell to ensure the convenience of docking between the end cover and the compressor shell.
[0009] Preferably, the vertical section of the positioning block is L-shaped, and the L-shaped vertical plate end of the positioning block is buckled on the surface of the rubber ring gasket. The rubber ring gasket can be buckled through the positioning block to prevent the rubber ring gasket from loosening and falling off on the surface of the inner ring.
[0010] Preferably, two rubber sockets are symmetrically connected to the left and right sides of the inner ring, and the rubber sockets are embedded in the inner wall of the compressor shell through slots. The rubber sockets can be buckled inside the slots on the inner wall of the compressor shell, and then the end cover is pre-assembled.
[0011] Preferably, a limiting screw sleeve is provided on the outer threaded sleeve of the screw barrel end of the compressor shell, and the limiting screw sleeve forms a limiting cavity adapted to the nut. The limiting screw sleeve is symmetrical with the screw barrel end of the compressor shell, so that the limiting cavity of the limiting screw sleeve can wrap and limit the nut.
[0012] Preferably, the outer sides of two adjacent limiting screw sleeves are connected with connecting tube ends, and the outer sides of the connecting tube ends are provided with fixing rings through ring groove sleeves. The two fixing rings are connected and fixed by beam rods, and are connected by two adjacent limiting screw sleeves, so that the two adjacent limiting screw sleeves can be stably fixed on the outer sides of the screw tube ends of the compressor casing to prevent a single limiting screw sleeve from loosening and detaching.
[0013] The utility model has at least the following beneficial effects:
[0014] 1. By setting a locking component and a limiting component, the end cover and the compressor shell can be conveniently connected. Compared with the traditional structure, the device passes through the inside of the screw barrel end of the compressor shell through a threaded shaft, and two nuts are threadedly sleeved on the outer surface of the threaded shaft to ensure the tightness of the connection between the end cover and the compressor shell. At the same time, the beam rod threaded sleeve is arranged on the outside of the screw barrel end of the compressor shell, so that the limiting screw sleeve wraps and limits the nut to prevent the nut from loosening. The outsides of the two limiting screw sleeves are connected with connecting barrel ends, and the two connecting barrel ends are limited by a fixing ring and the beam rod to prevent the independent limiting screw sleeve from falling off.
[0015] 2. By setting up the cover group, the tightness of the buckling between the end cover and the compressor shell is ensured. The device is arranged on the outside of the inner ring through the rubber ring gasket, so that the inner ring is inserted into the inside of the compressor shell. When the end cover and the compressor shell are docked, the rubber ring gasket can be squeezed to ensure the tightness of the docking between the end cover and the compressor shell. At the same time, the positioning plug can be inserted into the positioning groove of the compressor shell, so that the rubber socket can be buckled on the inner wall of the compressor shell, which is convenient for positioning and installing the end cover, ensuring the convenience of docking between the end cover and the compressor shell.
