Description

Technical Field

[0001] This utility model relates to the field of air conditioner compressor technology, specifically to an air conditioner compressor rotor that prevents the spring from popping out. Background Technology

[0002] The reciprocating operation of the pump body inside a rotary compressor relies heavily on the role of the spring. The spring uses its elastic force to keep the piston and other components firmly fixed in the correct position, thereby reducing pump noise, improving compression efficiency, and ensuring the normal operation of the compressor.

[0003] In most existing rotary compressors, the spring hole design of the cylinder has the following shortcomings: after the spring is inserted into the cylinder spring hole, it is easy to pop out, affecting the subsequent process time; when the spring position is close to the edge of the spring hole, after the compressor housing is pressed in, the actual state of the spring cannot be detected, and the spring may be pulled out, resulting in spring damage or breakage. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an air conditioner compressor rotor that prevents the spring from popping out.

[0005] An air conditioning compressor rotor for preventing spring ejection includes a lower support, a cylinder, an upper support, and a muffler mounted sequentially on a rotating shaft from bottom to top. The cylinder has a communicating blade groove and a spring hole. The blade groove has blades, and the spring hole has a spring. One end of the blade contacts the spring, and the other end contacts the outer wall of the transition ring mounted on the rotating shaft; Multiple blocking blocks are provided on the inner wall of the outer end of the spring hole. The blocking blocks do not protrude from the outer wall of the cylinder body, and the end of the spring away from the blade contacts the blocking block.

[0006] Preferably, the number of the blocking blocks is not less than three, and they are arranged in a circular array on the inner wall of the spring hole.

[0007] Preferably, the blocking block protrudes from the side wall of the cylinder toward the inner wall of the spring hole by being struck by a jig, and multiple grooves are formed on the side wall of the cylinder, with the position of one groove corresponding to the position of one blocking block.

[0008] Preferably, the depth of the groove is 0.4mm-0.6mm.

[0009] Preferably, the blocking block is fixed to the inner wall of the spring hole by welding.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a blocking block on the inner wall of the outer end of the spring hole to block the spring, the spring is prevented from popping out. Attached Figure Description

[0013] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0014] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0015] Please see Figures 1 to 4 An embodiment of the present invention provides an air conditioning compressor rotor for preventing spring ejection, comprising a lower support 12, a cylinder 13, an upper support 14 and a muffler 15 sequentially mounted on a rotating shaft 11 from bottom to top. The cylinder 13 is provided with a blade groove 131 and a spring hole 132 that are connected to each other. A blade 16 is provided in the blade groove 131 and a spring 17 is provided in the spring hole 132. One end of the blade 16 contacts the spring 17, and the other end contacts the outer wall of the transition ring 18 mounted on the rotating shaft 11; Multiple blocking blocks 133 are provided on the inner wall of the outer end of the spring hole 132. The blocking blocks 133 do not protrude from the outer wall of the cylinder body 13. The end of the spring 17 away from the blade 16 contacts the blocking block 133.

[0016] It should be noted that in this utility model, the spring 17 is first installed into the spring hole 132, and then the blocking block 133 is formed at the outer end of the spring hole 132 by a jig through a hammering method. The blocking block 133 protrudes from the side wall of the cylinder 13 toward the inner wall of the spring hole 132, thereby blocking the spring 17. At the same time, a plurality of grooves 134 are formed on the side wall of the cylinder 13, and the position of one groove 134 corresponds to the position of one blocking block 133.

[0017] In a preferred embodiment of the present invention, in order to ensure uniform force distribution, the number of the blocking blocks 133 is not less than three, and they are arranged in a circular array on the inner wall of the spring hole 132.

[0018] In a preferred embodiment of this utility model, in order to ensure the connection strength between the blocking block 133 and the cylinder 13, the depth of the groove 134 is 0.4mm-0.6mm.

[0019] In a preferred embodiment of this utility model, the blocking block 133 is fixed to the inner wall of the spring hole 132 by welding.

[0020] In summary, this utility model prevents the spring 17 from popping out by providing a blocking block 133 on the inner wall of the outer end of the spring hole 132 to block the spring 17.

[0021] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
