DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-5 The present invention provides a technical solution: a sealing assembly for an automobile air-conditioning compressor, comprising a body 1, a high-pressure hole 2 is provided on one side surface of the body 1 near the top; a low-pressure hole 3 is provided on one side surface of the high-pressure hole 2; a plurality of mounting members 4 are fixedly connected to the surface of the body 1; a clutch assembly 5 is fixedly connected to the other side surface of the body 1; a belt groove 6 is provided on one side surface of the clutch assembly 5 near the body 1; a plurality of belt grooves 7 are provided inside the belt groove 6; an oil filling pipe 8 is connected through one side surface of the body 1 near the middle; and further comprising: fixing assemblies 10 are symmetrically provided on both sides of the oil filling pipe 8; wherein the fixing assembly 10 comprises a connecting sleeve 1001 fixedly connected to the oil filling pipe 8; wherein a slide groove 1002 is provided inside the connecting sleeve 1001, such as Figure 1-5 As shown, by setting a fixing component 10, the fixing component 10 can perform a fixing and limiting function on the seal 9, thereby preventing the vibration force generated by the compressor during operation from separating the fixing component 10 from the seal 9, thereby causing the seal 9 and the oil filling pipe 8 to fall off. At the same time, by setting a belt groove 6, a plurality of V-shaped belt grooves 7 are set inside the belt groove 6, so that when a belt that is compatible with the belt groove 7 is used to transmit the clutch assembly 5, the contact area between the belt and the clutch assembly 5 becomes larger, so that the belt and the clutch assembly 5 will not slip, thereby improving the working efficiency of the compressor.

[0030] The inside of the slide groove 1002 is slidably connected with a clamping rod 1003, and a blocking plate 1004 is connected to the surface of one side of the clamping rod 1003. Both sides of the blocking plate 1004 are fixedly connected to the slide groove 1002. A spring 1005 is fixedly connected to the middle of the surface of the blocking plate 1004 away from the clamping rod 1003. A slide plate 1006 is fixedly connected to the surface of the spring 1005 away from the blocker 1004. The spring 1005 is sleeve-connected with the clamping rod 1003. Sliding grooves 1007 are symmetrically provided on both sides of the slide groove 1002. The sliding grooves 1007 are slidably connected to the slide plate 1006. Figure 4 , 5As shown, by pulling the card rod 1003, the card rod 1003 moves when subjected to a pulling force, and the movement of the card rod 1003 can drive the slide plate 1006 to move inside the slide groove 1002. The movement of the slide plate 1006 squeezes the spring 1005, so that the spring 1005 is deformed. At the same time, the spring 1005 is a compression spring 1005 in the prior art. At the same time, after the card rod 1003 is pulled to a certain position, the card rod 1003 is separated from the card groove 11, so that the seal 9 can be separated from the oil filling pipe 8, so that Lubricating oil must be injected through the oil filling pipe 8. At the same time, when fixing the seal 9, after the seal 9 is engaged on the oil filling pipe 8, the clamping rod 1003 is loosened, so that the clamping rod 1003 moves under the action of the spring 1005, so that the clamping rod 1003 and the clamping groove 11 are re-engaged together, thereby completing the fixing and limiting function of the seal 9. At the same time, the vibration generated by the operation of the compressor will only cause the spring 1005 to move slightly, and will not cause the separation between the clamping rod 1003 and the clamping groove 11, thereby avoiding the possibility of the seal 9 falling off.

[0031] A sealing member 9 is provided on the top surface of the oil filling pipe 8. Figure 2 , 3 As shown, through the action of the seal 9 , the seal 9 can perform a sealing action on the oil filling pipe 8 .

[0032] The sealing member 9 is symmetrically provided with a clamping groove 11 on both sides, the clamping groove 11 is clamped and connected with the clamping rod 1003, and the clamping rod 1003 is connected with the oil filling pipe 8 through and through. Figure 5 As shown, the engagement connection between the card slot 11 and the card rod 1003 can provide a stable limiting effect on the sealing member 9, thereby preventing the sealing member 9 from falling off.

[0033] Working principle: Before using this automotive air conditioning compressor sealing assembly, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 5As shown, first, when the sealing assembly needs to be disassembled, the clamping rod 1003 is pulled so that the clamping rod 1003 moves when subjected to tension, and the movement of the clamping rod 1003 can drive the slide plate 1006 to move inside the slide groove 1002, and the movement of the slide plate 1006 can squeeze the spring 1005, so that the spring 1005 is deformed, and the spring 1005 is a compression spring 1005 in the prior art, and after the clamping rod 1003 is pulled to a certain position, the clamping rod 1003 is separated from the clamping groove 11, so that the seal 9 and the oil injection can be separated. Tube 8 is separated, so that lubricating oil can be injected through the oil filling pipe 8. At the same time, when fixing the seal 9, after the seal 9 is engaged on the oil filling pipe 8, the clamping rod 1003 is loosened, so that the clamping rod 1003 moves under the action of the spring 1005, so that the clamping rod 1003 and the clamping groove 11 are re-engaged together, thereby completing the fixing and limiting function of the seal 9. At the same time, the vibration generated by the operation of the compressor will only cause the spring 1005 to move slightly, and will not cause the separation between the clamping rod 1003 and the clamping groove 11, thereby avoiding the possibility of the seal 9 falling off.

[0034] Secondly, by setting up the belt groove 6 and arranging a plurality of V-shaped belt grooves 7 inside the belt groove 6, when the clutch assembly 5 is transmitted by a belt matched with the belt groove 7, the contact area between the belt and the clutch assembly 5 becomes larger, so that the belt and the clutch assembly 5 will not slip, thereby improving the working efficiency of the compressor.

[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
