Technical Field

[0001] This utility model relates to the field of air conditioning compressor technology, specifically to a cylinder block for an automotive air conditioning compressor. Background Technology

[0002] The cylinder block of an automotive air conditioning compressor is one of the core structural components of the compressor. It is usually made of metal and its main function is to house and support key moving parts such as pistons, connecting rods, and valves. Together with the cylinder head, it forms a closed working volume. The reciprocating or rotating motion of the piston is used to compress and transport the refrigerant.

[0003] When the automotive air conditioning compressor lacks sufficient lubricating oil or contains impurities in the refrigerant, the friction between the piston and the cylinder increases, leading to cylinder scoring. The existing method for repairing cylinder scoring is generally to replace the entire cylinder, which is expensive. Therefore, a new automotive air conditioning compressor cylinder design is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automotive air conditioning compressor cylinder block, which has advantages such as reducing air conditioning compressor maintenance costs. It also solves the problem that the existing method for repairing cylinder scoring in compressors generally involves replacing the entire cylinder block, resulting in high maintenance costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cylinder block for an automotive air conditioning compressor, comprising a cylinder block and piston holes, wherein a plurality of piston holes are provided on the left side of the cylinder block, the plurality of piston holes being distributed in a ring at equal intervals on the left side of the cylinder block, a groove formed on the cylinder block being fixedly installed on the inner side wall of the piston hole, a piston sleeve being detachably installed in the piston hole, and a locking block being fixedly installed on the outer peripheral wall of the piston sleeve, the locking block matching the locking groove.

[0006] Furthermore, the outer peripheral wall of the piston sleeve is provided with a sliding groove, and a fixing block is slidably installed inside the sliding groove. The piston sleeve is fixedly connected to the cylinder body by screws, and the screws pass through the fixing block.

[0007] Furthermore, the slot has a threaded groove on the side wall inside the cylinder body, which matches the screw.

[0008] Furthermore, a positioning groove is provided on the inner wall of the piston hole on the clockwise side of the slot, and the positioning groove matches the card block.

[0009] Furthermore, a groove is provided on the side of the fixing block away from the card block, and a through hole is provided on the side of the fixing block close to the card block, with the groove and the through hole communicating with each other.

[0010] Furthermore, a sealing ring, which is a rubber ring, is provided on the side of the piston sleeve.

[0011] Furthermore, the piston sleeve has an installation groove on its side, and the sealing ring has a protrusion on the side that fits against the piston sleeve, with the protrusion tightly engaging with the installation groove.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects: This automotive air conditioning compressor cylinder block, through the design of piston sleeves and screws, allows for easy removal of the corresponding piston sleeve in the event of cylinder scoring in a certain area, eliminating the need to replace the entire cylinder block. This solves the problem that existing compressor cylinder scoring repair methods typically require replacing the entire cylinder block, resulting in high repair costs. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 In this embodiment, an automotive air conditioning compressor cylinder includes a cylinder 1 and piston holes 2. A plurality of piston holes 2 are provided on the left side of the cylinder 1. The plurality of piston holes 2 are distributed in a ring at equal intervals on the left side of the cylinder 1. A groove 3 formed on the cylinder 1 is fixedly installed on the inner side wall of the piston hole 2. A piston sleeve 4 is detachably installed in the piston hole 2. A locking block 5 is fixedly installed on the outer peripheral wall of the piston sleeve 4. The locking block 5 matches the groove 3.

[0017] In this embodiment, a positioning groove 11 is provided on the inner side wall of the piston hole 2 and on the clockwise side of the slot 3. The positioning groove 11 matches the slot 5.

[0018] Specifically, the positioning groove 11 can prevent the piston sleeve 4 from shifting position as the piston reciprocates, thus ensuring that the piston sleeve 4 can be installed securely.

[0019] In this embodiment, a groove 41 is provided on the outer peripheral wall of the piston sleeve 4, and a fixing block 42 is slidably installed inside the groove 41. The piston sleeve 4 is fixedly connected to the cylinder 1 by a screw 6, and the screw 6 passes through the fixing block 42.

[0020] Specifically, the piston sleeve 4 is fixedly installed on the cylinder block 1 by screws 6. When cylinder scoring occurs in a certain area, only the piston sleeve 4 of the corresponding area needs to be removed, without replacing the entire cylinder block.

[0021] In this embodiment, the slot 3 is provided with a threaded groove 12 on the side wall inside the cylinder 1, and the threaded groove 12 matches the screw 6.

[0022] Specifically, the threaded groove 12 allows the screw 6 to be tightened onto the cylinder 1.

[0023] In this embodiment, a groove 43 is provided on the side of the fixing block 42 away from the card block 5, and a through hole 44 is provided on the side of the fixing block 42 close to the card block 5. The groove 43 and the through hole 44 are connected.

[0024] Specifically, the through hole 44 allows the screw 6 to pass through the fixing block 42, and the groove 43 allows the head of the screw 6 to retract into the fixing block 42.

[0025] In this embodiment, a sealing ring 7 is provided on the side of the piston sleeve 4, and the sealing ring 7 is a rubber ring.

[0026] Specifically, the sealing ring 7 ensures the sealing performance of the cylinder.

[0027] In this embodiment, the piston sleeve 4 has an installation groove 45 on its side, and the sealing ring 7 has a protrusion 71 on the side that fits against the piston sleeve 4. The protrusion 71 is in close contact with the installation groove 45.

[0028] Specifically, the protrusion 71 and the mounting groove 45 enable the sealing ring 7 to be installed securely; at the same time, when installing the piston sleeve 4, needle-nose pliers can be used to reach into the mounting groove 45 and rotate the piston sleeve 4, thus avoiding damage to the piston sleeve 4 during installation.

[0029] The working principle of the above embodiments is as follows: (1) When the cylinder body is caught, remove the sealing ring 7, unscrew the screw 6, and release the piston sleeve 4 from its fixed state. At this time, when the piston sleeve 4 rotates counterclockwise, the screw 6 will not block the block 5. (2) Rotate the piston sleeve 4 counterclockwise. The piston sleeve 4, along with the locking block 5, moves from the positioning groove 11 to the locking groove 3. The piston sleeve 4 can be removed by pulling it out. (3) Insert the locking block 5 on the new piston sleeve 4 into the slot 3, rotate the piston sleeve 4 clockwise, and screw in the screw 6 to complete the installation of the piston sleeve 4.
