The machine head includes a housing and a motor. The motor is located inside the housing, and the housing is located between the left support frame and the right support frame. With such a design, the architecture layout of the air compressor is compact, which is conducive to the miniaturization of the air compressor.

[0004] However, during the workshop processing of this patent, it is inconvenient for the overhead crane to lift the air compressor, thus reducing its practicability.

[0005] Now a concealed lifting structure for an air compressor is provided. Summary of the Utility Model

[0032] The present disclosure will be described in detail below with reference to the drawings and in combination with embodiments.

[0033] Refer to Figures 1-3 , a hidden hoisting structure for an air compressor, comprising: a compressor body 1, a hoisting groove 2, a hoisting rod 3, a fixed ring 4, and an extrusion assembly. The hoisting groove 2 is opened on the compressor body 1. The hoisting rod 3 is fixedly connected between the two inner walls of the hoisting groove 2. Two fixed rings 4 are provided and symmetrically slidably installed on the hoisting rod 3. The extrusion assembly is arranged between the fixed ring 4 and the inner wall of the hoisting groove 2 and is used to squeeze the two fixed rings 4 to approach each other. The fixed ring 4 is sleeved on the hoisting rod 3. Friction plates 11 are fixedly connected to the ends of the two fixed rings 4 that approach each other.

[0034] The extrusion assembly includes two mounting cylinders 8, which are respectively fixedly connected to the two inner walls of the hoisting groove 2, and the two fixing rings 4 are located between the two mounting cylinders 8. A sliding groove 10 is formed on the mounting cylinder 8, and a connecting rod 5 is slidably mounted on the sliding groove 10, and the connecting rod 5 is fixedly connected to the fixing ring 4. A fixing spring 6 is fixedly connected between the fixing ring 4 and the mounting cylinder 8. The fixing spring 6 is sleeved on the connecting rod 5. The mounting cylinder 8 is sleeved on the hoisting rod 3. There are two fixing springs 6 and two connecting rods 5 respectively.

[0035] A limiting groove 9 is formed on the inner wall of the sliding groove 10, and a limiting block 7 corresponding to the limiting groove 9 is fixedly connected to the connecting rod 5. There are two limiting blocks 7 and two limiting grooves 9 respectively. The connecting rod 5 is located between the two limiting blocks 7.

[0036] Working process: By providing the hoisting rod 3, when machining an air compressor, it is convenient for the hook of the workshop overhead crane to lift the compressor body 1. When it is necessary to lift the compressor body 1 with a hook, first hook the hook on the hoisting rod 3, and at the same time make the hook located between the two fixing rings 4. Then, under the action of the fixing spring 6, the two fixing rings 4 are squeezed to approach each other, so that the two fixing rings 4 clamp and fix the hook, thereby improving the stability of the hook hooked on the hoisting rod 3. And under the action of the friction plate 11, the friction is increased, further improving the stability. And under the action of the limiting rod, the connecting rod 5 is prevented from detaching from the mounting cylinder 8.

[0037] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles.
