Problems solved by technology

[0003] In the above fastening method, since the fastening nut 30 and the junction box cover 20 adopt a split design, there is no assembly relationship between the two, so they need to be stored separately, which increases storage costs. Fastening nut 30 is easy to lose before assembly, thus affecting

Abstract

The invention discloses a preassembling fastening assembly and a compressor, and belongs to the technical field of compressor assembling. The preassembling fastening assembly comprises a first to-be-fastened piece and a fastening piece. The fastening piece comprises a second limiting structure, a connecting structure and a first limiting structure, all of which are connected in sequence. The connecting structure of the fastening piece can be assembled into a first connecting hole in the first to-be-fastened piece in advance, movement of the fastening piece in the axis direction of the fastening piece can be limited through cooperation of the first limiting structure and the second limiting structure, the connecting structure is limited in the first connecting hole, and therefore the fastening piece is prevented from falling off from the first to-be-fastened piece. Compared with a first to-be-fastened piece and a fastening piece which are designed in a split manner in the prior art, bymeans of the preassembling fastening assembly, the storage cost can be reduced, the fastening piece is prevented from being lost before assembling, the assembling efficiency of later assembling can beimproved, and the phenomenon that the fastening piece accidentally falls off in the later assembling process is avoided.

Description

technical field [0001] The invention relates to the technical field of compressor assembly, in particular to a pre-installed fastening assembly and a compressor. Background technique [0002] A compressor is a driven fluid machine that elevates low-pressure gas to high-pressure gas, and is an important component of a refrigeration system. Such as figure 1 As shown, the existing compressor includes a compressor housing 10 and a terminal box cover 20, the compressor housing 10 is provided with a positioning bolt 40, and the terminal box cover 20 is installed on the positioning bolt 40 using a fastening nut 30, thereby realizing Connection of the compressor housing 10 and the junction box cover 20 . The fastening method of the junction box cover 20 on the compressor casing 10 is as follows: Figure 2 to Figure 5 As shown, first place the junction box cover 20 above the compressor housing 10, align the connection holes on the junction box cover 20 with the positioning bolts 4...
