[0024] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0025] Embodiment: Please refer to Figures 1 to 5 According to the embodiment of the present application, a technical solution is provided: a screw air compressor transmission mechanism, comprising: an air compressor body 1; a motor 2, the output end of the motor 2 is connected to the screw end of the air compressor body 1 through a coupling 15; an adjusting mechanism, which comprises a sliding rail 3, a mounting plate 4, a limiting block 5, the sliding rail 3 can be installed on the ground, the mounting plate 4 is embedded and slidingly connected with the sliding rail 3, the limiting block 5 is fixed at one end of the sliding rail 3 located at the air compressor body 1, the limiting block 5 can be fixed to the ground, the side of the mounting plate 4 facing the limiting block 5 is provided with a hook 6, the side of the limiting block 5 facing the mounting plate 4 is provided with an L-shaped limiting hole 7 matched with the hook 6, after the hook 6 is inserted into the limiting hole 7, the limiting hole 7 limits the hook 6 from being pulled out, a reset hole 8 is formed at the top of the limiting block 5, a reset push rod 9 is slidingly connected in the reset hole 8, and the reset hole 8 is communicated with the limiting hole 7.

[0026] In the process of installing the air compressor and the motor 2, when the two are fixed, installing the coupling 15 connecting them often faces many inconveniences, the operation space is limited, and it is difficult to accurately align, which is more prominent, which will increase the difficulty of installing the coupling 15, consume more time and labor cost, and even may affect the subsequent operation stability of the entire air compressor transmission system.

[0027] After the screw air compressor transmission mechanism with the above structure is adopted, the slide rail 3 can be installed on the ground first as the basic support part of the whole adjusting structure. Since the installation plate 4 is embedded with the slide rail 3 and can be connected in a sliding manner, the installation plate 4 can move freely along the slide rail 3. In this way, when the coupling 15 needs to be installed, the motor 2 fixed on the installation plate 4 can be moved in a sliding manner away from the air compressor body 1 to increase the gap between the motor 2 and the air compressor body 1, so as to facilitate fine alignment operation when the coupling 15 is installed. Then, the installation plate 4 is pushed to move towards the limiting block 5. After the hook 6 is inserted into the limiting hole 7, the L-shaped structure of the limiting hole 7 can effectively prevent the hook 6 from being pulled out, so that the installation plate 4 can be fixed at the required position, and the position of the motor 2 or the air compressor body 1 fixed on the installation plate 4 is indirectly fixed. This ensures that there is no random displacement during normal operation, and the stability of the transmission is ensured. This structure effectively solves the problem of difficult installation of the coupling 15 caused by fixing the air compressor and the motor 2. It improves the convenience and efficiency of installation, ensures the stable and reliable operation of the whole screw air compressor transmission system, and solves the problem in the prior art that the distance between the air compressor and the motor 2 is difficult to adjust, which easily leads to long installation time and low installation efficiency.

[0028] The air compressor body 1, the motor 2 and the adjusting mechanism are all installed on the grounding plate 10, and the grounding plate 10 is fixed on the ground. Compared with the mode that each component is directly installed on the ground or fixed separately, the integrated installation on the grounding plate 10 can better resist external disturbances such as vibration and impact force generated during equipment operation, reduce the possibility of displacement and loosening of each component due to uneven force or shaking, and thus ensure the structural stability of the whole system during long-time operation.

[0029] The two hooks 6 on the installation plate 4 are located at the top of the two slide rails 3, and the reset push rod 9 is in the shape of a Chinese character 'fang'. The two ends of the 'fang'-shaped reset push rod 9 are inserted into the reset holes 8. The two hooks 6 on the installation plate 4 are located at the top of the two slide rails 3, which can provide more stable fixing effect. When the two hooks 6 are inserted into the corresponding limiting holes 7, the installation plate 4 is limited from different positions, so that the installation plate 4 is less likely to shake or deviate in each direction, thereby ensuring that the motor 2 (or the air compressor body 1) fixed on the installation plate 4 and the air compressor body 1 (or the motor 2) maintain a relatively accurate and stable positional relationship, which is conducive to the normal work of the coupling 15 and the stable operation of the whole transmission mechanism.

[0030] The limiting block 5 is slidably connected with the slide rail 3, the grounding plate 10 is provided with a tooth groove 11, the limiting block 5 is provided with a limiting gap 12 on the side facing the air compressor body 1, the limiting gap 12 is hingedly connected with a pushing piece 13, the pushing piece 13 is provided with a spring 14 on one end of the limiting gap 12, the spring 14 abuts against the limiting block 5 and the pushing piece 13, and the pushing piece 13 is embedded in the tooth groove 11 to limit the sliding of the limiting block 5 towards the air compressor body 1.

[0031] Since the limiting block 5 is slidably connected with the slide rail 3, during the actual installation and adjustment of the screw air compressor transmission mechanism, the position of the limiting block 5 on the slide rail 3 can be flexibly adjusted according to specific conditions, such as different initial distances between the air compressor body 1 and the motor 2, the precise position required during the installation of the shaft coupling 15, etc., thereby changing the position relationship between the mounting plate 4 and the components thereon relative to the air compressor body 1, and further improving the adjustment flexibility of the entire transmission mechanism during the installation stage, which helps to more accurately complete the positioning and installation of the components.

[0032] The tooth groove 11 provided on the grounding plate 10, the pushing piece 13 hingedly connected in the limiting gap 12 of the limiting block 5 facing the air compressor body 1, and the spring 14 connected between the pushing piece 13 and the limiting block 5 form a limiting structure, the spring is between the pushing piece 13 and the limiting block 5 and abuts against each other, so that the pushing piece 13 is subjected to the elastic force of the spring 14 in the normal state and maintains a relatively stable state, and the pushing piece 13 can be embedded in the tooth groove 11 of the grounding plate 10, when the pushing piece 13 is embedded in the tooth groove 11, due to the shape of the tooth groove 11 and the blocking effect of the teeth, the sliding of the limiting block 5 towards the air compressor body 1 is limited, and when the position of the limiting block 5 needs to be adjusted again, only a certain external force is applied to overcome the elastic force of the spring 14 to press down the pushing piece 13, so that the limiting state is released, and the limiting block 5 can freely slide along the slide rail 3, which is convenient for subsequent position adjustment according to actual needs, and the operation is relatively simple, which provides convenience for multiple debugging, maintenance and adjustment of the equipment.

[0033] Since the limiting structure composed of the tooth groove 11 and the pushing piece 13 on the limiting block 5 plays a key limiting role in limiting the sliding of the limiting block 5 towards the air compressor body 1, if the end of the slide rail 3 facing the air compressor body 1 exceeds the tooth groove 11, then during the installation, adjustment and subsequent equipment operation, the movement range of the limiting block 5 may be interfered by the exceeding part of the slide rail 3, which leads to the fact that the pushing piece 13 cannot be accurately embedded in the tooth groove 11 or easily accidentally separated from the tooth groove 11 in the normal limiting state, thereby affecting the normal play of the entire limiting function. By designing the slide rail 3 such that the end thereof facing the air compressor body 1 does not exceed the tooth groove 11, sufficient and appropriate space conditions are provided for the pushing piece 13 to be smoothly embedded in the tooth groove 11 and stably play the limiting role, so as to ensure that the limiting block 5 can be reliably limited when needed, and the stable state of the entire adjustment mechanism and the transmission mechanism is maintained.

[0034] While the embodiments of the present application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
