[0028] like Figure 1-4As shown, a new metal relay cover for a piston compressor according to an embodiment of the utility model comprises a relay cover housing 1 arranged at the top and a relay protection frame 2 arranged at the bottom, a protruding guide block 3 and a first screw hole 4 are arranged on the side wall of the relay cover housing 1, a guide opening 5 and a second screw hole 6 are respectively arranged on the side wall of the relay protection frame 2 at positions corresponding to the protruding guide block 3 and the first screw hole 4, and the first screw hole 4 and the second screw hole 6 are fixedly connected by screws.

[0029] According to a new metal relay cover for a piston compressor described in an embodiment of the utility model, in a specific embodiment, the positions and sizes of the raised guide block 3 and the guide opening 5 are correspondingly arranged, and the connection between the guide block 3 and the guide opening 5 is an interference fit.

[0030] According to a novel metal relay cover for a piston compressor described in an embodiment of the utility model, in a specific embodiment, the height dimension of the protruding guide block 3 protruding from the relay cover housing 1 is greater than or equal to the thickness dimension of the side wall of the relay protection frame 2.

[0031] According to the novel metal relay cover of a piston compressor described in an embodiment of the utility model, in a specific embodiment, the raised guide block 3 and the guide opening 5 are set equal and correspondingly in position, and the number of the two is at least one.

[0032] According to the novel metal relay cover of a piston compressor described in an embodiment of the utility model, in a specific embodiment, the raised guide block 3 is a rectangular raised guide block, and the guide opening 5 is adapted to the shape of the rectangular raised guide block.

[0033] According to the novel metal relay cover of a piston compressor described in an embodiment of the utility model, in a specific embodiment, the raised guide block 3 is a hemispherical raised guide block, and the guide opening 5 is adapted to the shape of the hemispherical raised guide block.

[0034] According to a new metal relay cover for a piston compressor described in an embodiment of the utility model, in a specific embodiment, the distance between the raised guide block 3 and the side edge of the relay cover housing 1 and the distance between the guide port 5 and the side edge of the relay protective frame 2 are both greater than or equal to 15 mm.

[0035] According to the novel metal relay cover of a piston compressor described in an embodiment of the utility model, in a specific embodiment, the protruding guide block 3 is an elastic protruding guide block.

[0036] According to the novel metal relay cover of a piston compressor described in an embodiment of the utility model, in a specific embodiment, the screw is a grounding screw 7.

[0037] In order to facilitate understanding of the above technical solution of the present invention, the above technical solution of the present invention is described in detail below through specific usage.

[0038] During specific use, according to the new metal relay cover of a piston compressor described in the utility model, a group of mutually interlocking guide components are designed at the contact portion between the relay protection frame 2 and the relay cover shell 1, that is: a protruding guide block 3 is designed on the relay cover shell 1, and a mutually interlocking guide opening 5 notch is designed at the matching portion between the relay protection frame 2 and the relay cover shell 1. During the matching process between the relay cover shell 1 and the relay protection frame 2, since the protruding guide block 3 has a certain elasticity, it will shrink to a certain extent after being subjected to the force of installation, thereby entering the guide opening 5 of the relay protection frame 2. After the protruding guide block 3 enters the guide opening 5 of the relay protection frame 2, the force of installation stops, the protruding guide block 3 returns to its original state, and performs interference fit with the guide opening 5 of the relay protection frame 2, so that the relay cover shell 1 and the relay protection frame 2 are interlocked, and at the same time, the grounding screw 7 is used for fastening, so that the relay cover shell 1 and the relay protection frame 2 are better fixed.

[0039] The structure of the utility model not only facilitates the fixing of the relay cover housing 1 and the relay protection frame 2, but also achieves the purpose of eliminating the traditional cover clip 8. In addition, it should be noted that the shape of the protection frame gap is not unique, and it can satisfy the cooperation between the relay protection frame 2 and the relay cover housing 1; for example, the raised guide block 3 in one embodiment of the utility model is a rectangular raised guide block, and the raised guide block 3 in another embodiment is a hemispherical raised guide block.

[0040] To sum up, with the help of the above-mentioned technical scheme of the utility model, through the optimization and improvement design of the product of the utility model, the guide structure on the metal relay cover and the notch of the protective frame are interlocked, which not only eliminates the cover card, but also can achieve the effect of the cover card, and also adds fastening screws, so that the metal relay cover is not easy to fall off, thereby saving installation time cost and improving production efficiency.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
