According to one embodiment of the application, the bottom of the female joint component 1 of the multi-stage sealing structure of the compressor is provided with a main annular groove 7 for extending into the annular fixed seat 9 of the sealing element.
According to an embodiment of the present application, a side pressing screw hole 14 for extending into the outer pressing screw 6 is provided on a side end surface of the outer fixing nut 4 of the multi-stage sealing structure of the compressor, and a side circular groove 13 for extending into the outer pressing screw 6 is provided on an outer end surface of the main annular groove 7.
According to an embodiment of the present application, the multi-stage sealing structure of the compressor further includes an outer clamping screw locking member 15, the outer clamping screw locking member 15 is a plate-shaped structure with an L-shaped longitudinal section, a nut receiving hole 21 and an inner insertion rod member 22 are provided on a side end surface of the outer clamping screw locking member 15, a fourth magnet member 23 is provided at a terminal of the inner insertion rod member 22, an upper strip-shaped groove 16 is provided at an edge of an upper end surface of the outer fixing nut 4, a first magnet member 17 is provided at a bottom of the upper strip-shaped groove 16, a side end surface of the outer fixing nut 4 is provided with a side circular hole portion 19 for inserting the inner insertion rod member 22, and a second magnet member 18 is provided inside the side circular hole portion 19. The multi-stage sealing structure of the compressor is based on sealing and mainly comprises that a sealing ring-shaped fixed seat 9 is stably embedded in a main ring-shaped groove 7, an outer pressing screw 6 is the only part for fixing and limiting the sealing ring-shaped fixed seat 9, if the sealing ring-shaped fixed seat 9 is loosened and even drops, the sealing performance of the structure is greatly influenced, therefore, an outer pressing screw anti-loosening part 15 covering the outer part of the outer pressing screw 6 is supplemented outside the outer pressing screw 6, so that the outer pressing screw 6 can be prevented from being loosened due to mistaken touch, and the outer pressing screw 6 can also be limited to a certain extent, as shown in figures 5 to 6, first magnet parts 17 and 20 are magnet sheet structures which are mutually adsorbed, a second magnet part 18 and a fourth magnet part 23 are cylindrical magnet block structures which are mutually adsorbed, when the outer pressing screw 6 is screwed, the inner insertion rod member 23 of the outer clamping screw locking member 15 can be inserted into the side circular hole portion 19, the upper portion of the outer clamping screw locking member 15 is embedded into the first magnet member 17, and the outer clamping screw locking member 15 is fixed to the outer fixing nut 4 under the mutual adsorption of the two magnetic forces, so that the outer clamping screw 6 is protected from being touched.
According to one embodiment of the application, the outer end face of the annular fixed seat 9 of the sealing element of the multi-stage sealing structure of the compressor is provided with a first thread, and the side end face of the main annular groove 7 is provided with a second thread engaged with the first thread.
According to an embodiment of the present application, the upper end face of the annular rubber seal 8 of the compressor multi-stage sealing structure is provided with an upper circular groove 12.
According to one embodiment of the application, the outer end face of the top of the inner extension ring 3 of the multi-stage sealing structure of the compressor is provided with an external thread, and the inner end face of the outer fixing nut 4 is provided with an internal thread.
According to an embodiment of the application, when the multistage sealing structure of the compressor is used, the inward extending ring 3 can be inserted into the outer fixing nut 4, and the annular sealing protrusion 10 is inserted into the annular groove on the lower end face of the annular fixing seat 9 of the sealing element, so that the top of the annular sealing protrusion 10 and the bottom of the compression annular rubber sealing element 8 are both arc-shaped in longitudinal section, therefore, the stress is uniform during compression, and the annular sealing protrusion 10 can cause smaller damage than a prismatic plane structure if being scraped during insertion; meanwhile, in the structure disclosed in the patent document with the publication number of CN205781523U, the sealing element is directly pressed in the pressure-filling space, if fixing is desired, industrial glue is needed for adhesion, or the sealing element is directly placed in the pressure-filling space without fixation, and the two methods are inconvenient when the sealing element needs to be taken out and replaced after long-term use, but the structure of the multi-stage sealing structure of the compressor can solve the problem, when the sealing element needs to be taken out, the annular fixing seat 9 of the sealing element can be turned down, and a rod extends into the upper circular groove 12 to pick out the annular rubber sealing element 8, (the annular fixing seat 9 of the sealing element and the annular rubber sealing element 8 can be connected by a thread structure, and at this time, the rod can be inserted into the upper circular groove 12 to drive the annular rubber sealing element 8 to rotate to take out the annular; the reason why the structure described in patent document CN205781523U cannot be perforated for easy removal is that the sealing member has only one surface facing outward, and if the sealing member is perforated, the sealing member is of an integrally sealed type, but the structure is perforated because the upper end surface of the annular rubber sealing member 8 does not directly contact the annular sealing groove 11, and the sealing property is not affected by the perforation.
According to an embodiment of the present application, when the annular fixed seat 9 of the sealing member of the multi-stage sealing structure of the compressor is rotated into the main annular groove 7 to a fully compressed position by the screw structure, the side compression screw hole 14 and the side circular groove 13 are communicated with each other, and at this time, the outer compression screw 6 can be inserted to fix the annular fixed seat 9 of the sealing member.
According to an embodiment of the application, the top of the annular sealing protrusion 10 is set to be in the shape of an arc and the top of the inner end face of the annular sealing groove 11 is set to be in the shape of an arc, so that the joint of the annular sealing protrusion 10 and the annular rubber sealing element 8 can be in a smooth structure, pressure applied to the annular rubber sealing element 8 during pressing can be more uniform, the phenomenon that the annular rubber sealing element 8 is locally pressed and deformed can be avoided, and the annular sealing protrusion 10 is prevented from deviating a small amount in the process of entering the annular sealing groove 11 to scratch other components. The outer tightening screw anti-loosening component 15 can be fixed outside the outer tightening screw 6 by arranging the outer tightening screw anti-loosening component 15, the upper strip-shaped groove 16, the first magnet component 17, the second magnet component 18, the side round hole portion 19, the third magnet component 20, the nut bearing hole 21, the inner insert rod component 22 and the fourth magnet component 23, so that the sealing type is prevented from being influenced by the fact that the sealing ring-shaped fixed seat 9 is loosened inside the main ring-shaped groove 7 due to mistaken collision and loosening in the outer tightening screw 6.
The above-described embodiments are merely illustrative of several embodiments of the present invention, which are described in detail and detail, but should not be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
