Problems solved by technology
Therefore, the two legs of the air-conditioning compressor and the two legs of the bracket will generate bending stress accordingly, and the bending stress will be released by the long-term vibration of the engine, which will easily cause the legs of the air-conditioning compressor to break and affect the normal operation of the air-conditioning compressor

Embodiment Construction
[0022] The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, so as to further illustrate the purpose, scheme and effect of the present invention. However, the description is not intended to limit the protection scope of the appended claims of the present invention.
[0023] Such as image 3 As shown, the engine air-conditioning compressor fixing device according to a preferred embodiment of the present invention includes a fixing bolt 1, a leg 2 (including a first leg 21 and a second leg 22), a bracket 3, a mosaic looper 4, a flat washer 5, Spring washer 6, nut 7 and guide positioning pin 8. Only one set of legs and corresponding brackets 3, inlaid loopers 4, flat washers 5, spring washers 6, nuts 7 and guide positioning pins 8 are shown in the figure. Another set of legs and corresponding parts and structures are the same. The following description only takes a set of f...

The invention discloses an air condition compressor fixing device and an engine and an automobile provided with the same. The air condition compressor fixing device for the engine comprises a stand bar, a support, a fixed bolt for passing through the stand bar and the support, a nut suitable for threaded connection with the fixed bolt, and a mosaic loop which can be arranged in the support only by a way of slipping along the axial direction of the fixed bolt, wherein the mosaic loop is provided with internal threads suitable for threaded connected with a thread part of the fixed bolt. Therefore, the attachment strength of the threaded connection directly extrudes two sides of a protrusion of the support, and no bending stress is generated on the stand bar and the support; in addition, when a large gap exists between the stand bar and the support, the mosaic loop can slip to abut against a protrusion of the stand bar, so the requirement on matching precision is reduced.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to an air-conditioning compressor fixing device for automobiles, an engine and an automobile with the fixing device. Background technique [0002] The air conditioner compressor is a common device to adjust the temperature inside the car, and is usually fixedly installed on the engine through a fixing device installed on the engine cylinder head. [0003] In the prior art, the air conditioner compressor has forked legs (or a group of legs, each group of legs includes two legs, and each group of legs is regarded as a fork leg 2), and the fixing device has forked legs. bracket, and the connection is usually achieved by inserting the fork bracket between the two branches of the fork leg so that the through holes in the two branches of the fork leg align with the through holes in the two branches of the fork bracket , and then pass the fixing bolt 1 through the four through holes, ...
