Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a cylinder cover card fool-proof installation structure for compressors. Background Art

[0002] Piston compressors are widely used in refrigerators and other refrigeration equipment. The structure of piston compressors is relatively mature. Its cylinder head is equipped with a cylinder head, and the lower end of the cylinder head is equipped with an intake muffler through a cylinder head clamp. The intake muffler is pressed by the elastic force of the cylinder head clamp. However, compressor manufacturers have the following problems in the actual assembly process: generally, the cylinder head clamp is first installed into the mounting groove of the cylinder head, and then the intake muffler is installed. The three are installed in a split manner. During actual installation, the cylinder head clamp is easy to be misplaced or not installed in place, the installation direction is difficult to distinguish, and the assembly process is poor, resulting in the intake muffler not being fully installed in place. If the compressor is incorrectly installed, the compressor may easily cause valve plate rupture, compressor cross-flow, jamming and other serious phenomena during operation. Therefore, it is necessary to design a fool-proof installation structure for the cylinder head clamp to reduce or even avoid the phenomenon of incorrect installation of the cylinder head clamp. Summary of the invention

[0003] The purpose of the utility model is to solve the problems existing in the above-mentioned prior art and to provide a fool-proof installation structure for a cylinder cover of a compressor.

[0004] The specific scheme of the utility model is: a fool-proof installation structure of a cylinder head card for a compressor, comprising an intake muffler, a cylinder head and a cylinder head card, the cylinder head card is provided with a pressure plate that fits with the intake muffler, a raised buckle is provided on the back of the head of the intake muffler, a card slot is formed between the buckle and the intake muffler, the card slot matches the pressure plate so that the cylinder head card is tightly inserted in the card slot, thereby making the cylinder head card tightly connected to the intake muffler.

[0005] Furthermore, the buckle is composed of two symmetrically arranged L-shaped protrusions, and the space between the two L-shaped protrusions forms the clamping slot.

[0006] Furthermore, a limiting boss is provided on the outer wall of the suction muffler below each of the two L-shaped protrusions.

[0007] Furthermore, an arc transition surface is provided at the upper end of one side opposite to the two L-shaped protrusions, and the arc transition surface is used to facilitate the cylinder cover card to be inserted into the card slot.

[0008] Compared with the prior art, the utility model has the following advantages: the cylinder cover card is first installed as a whole with the intake muffler, and then the whole is installed in the installation groove of the cylinder cover, which can play a fool-proof role and improve the consistency of the product.

[0016] See also Figure 1-6 The present embodiment is a foolproof installation structure of a cylinder head card 6 for a compressor, comprising an intake muffler 1, a cylinder head 4 and a cylinder head card 6. The cylinder head card 6 is provided with a pressing plate 5 which fits with the intake muffler 1. A raised buckle is provided on the back of the head of the intake muffler 1. A slot is formed between the buckle and the intake muffler 1. The slot matches the pressing plate 5 so that the cylinder head card 6 is tightly inserted into the slot, thereby making the cylinder head card 6 and the intake muffler 1 tightly connected.

[0017] Furthermore, the buckle is composed of two symmetrically arranged L-shaped protrusions 2, and the space between the two L-shaped protrusions 2 forms the clamping groove.

[0018] Furthermore, a limiting boss 3 is provided on the outer wall of the suction muffler 1 below each of the two L-shaped protrusions 2 .

[0019] Furthermore, an arc transition surface is provided at the upper end of one side opposite to the two L-shaped protrusions 2, and the arc transition surface is used to facilitate the cylinder head card 6 to be inserted into the card slot from top to bottom.

[0020] The pressure plate 5 described in this embodiment is generally rectangular, and its width and thickness match the slot. Therefore, during assembly, the cylinder head clip 6 can be first installed in the slot of the intake muffler 1 and fixed, and then the intake muffler 1 and the cylinder head clip 6 can be integrally installed in the installation slot of the cylinder head 4. This can not only prevent the cylinder head clip 6 from falling off during the assembly process, but also make the assembly operation more convenient and improve the assembly efficiency. At the same time, since the cylinder head clip 6 cannot be installed into the slot in reverse, it has a certain anti-fool effect and improves the stability of product quality.
