However, since most of the structure of the screw air compressor body is located inside the protective shell, it is difficult to inspect the main structure deep inside the protective shell only through the inspection door, which affects the staff's disassembly and maintenance operations and brings inconvenience to the users. Therefore, a screw air compressor that is easy to maintain is proposed to solve the above-mentioned problem.

[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] The present application embodiment discloses a screw air compressor that is easy to maintain. Figure 1-4, a screw air compressor that is easy to maintain, includes a base 1 and an air compressor body 2 installed on the top outer wall of the base 1, the top outer wall of the base 1 is fixedly connected to a connecting frame 3, the top outer wall of the base 1 is symmetrically hinged with two shells 4, the two shells 4 are rotated upward and are both sleeved on the outer wall of the connecting frame 3, the two shells 4 and the connecting frame 3 form a protective shell for protecting the air compressor body 2, the top outer walls of the two shells 4 are installed with a locking mechanism that is easy to open and close, the locking mechanism includes two fixed rods 13 fixedly connected to the top outer wall of the shell 4, the outer walls of the two fixed rods 13 are slidably connected to a movable plate 8, the outer wall of the movable plate 8 on one side of the shell 4 is fixedly connected to a card block 9, the outer wall corresponding to the connecting frame 3 and the two movable plates 8 is provided with two card slots 5, the bottom ends of the two card blocks 9 penetrate the shell 4 and are clamped with the two card slots 5, and the outer walls of multiple fixed rods 13 are all sleeved with springs 11.

[0021] The locking mechanism also includes a plurality of L-shaped fixing plates 12 fixedly connected to the top outer walls of the two shells 4, the top ends of a plurality of fixing rods 13 are respectively fixedly connected to the top inner walls of the plurality of L-shaped fixing plates 12, and the spring 11 is located between the movable plate 8 and the L-shaped fixing plate 12.

[0022] The middle top outer walls of the plurality of movable panels 8 are all fixedly connected with pull rods 10 .

[0023] Two inspection doors 7 are hinged on the outer walls of the two shells 4 facing each other. The inspection doors 7 can be opened to facilitate daily maintenance and observation of the structure of the air compressor body 2.

[0024] The outer walls of the two shells 4 on the opposite sides are fixedly connected with handles 6, and the handles 6 are close to the top of the shells 4. By holding the handles 6, the shells 4 can be easily rotated upward or downward for opening and closing operations.

[0025] The implementation principle of the screw air compressor that is easy to maintain in the embodiment of the present application is as follows: in actual application, by opening multiple inspection doors 7, it is convenient to conduct daily observation and maintenance of some structures on the surface of the air compressor body 2. When it is necessary to repair the structure deep inside the air compressor body 2, it is difficult to access the structure deep inside the air compressor body 2 only through multiple inspection doors 7, and the narrow space is not conducive to maintenance by operators. At this time, through the locking mechanism, the two pull rods 10 are pulled upward, and the two pull rods 10 drive the two movable plates 8 to slide upward on the outer walls of the multiple fixed rods 13, and the movable plates 8 drive the card blocks 9 to break away from the inner walls of the card slots 5, unlocking the two shells 4, and the two shells 4 can be opened by turning the shells 4 downward by the handle 6, so that the structure of the air compressor body 2 can be fully exposed, which is convenient for operators to perform maintenance and inspection;

[0026] After the inspection is completed, the two shells 4 are rotated upward to close. When the shell 4 drives the block 9 in the locking mechanism to contact the outer wall of the connecting frame 3, the inclined surface at the bottom end of the block 9 contacts the outer wall of the connecting frame 3, and the block 9 can be easily pushed upward. The block 9 drives the movable plate 8 to slide upward and cooperate with the L-shaped fixed plate 12 to squeeze the spring 11. The spring 11 deforms and accumulates elastic force. When the shell 4 is completely sleeved with the connecting frame 3, the block 9 will be aligned with the two slots 5 on the outer wall of the connecting frame 3. The outer wall of the connecting frame 3 no longer squeezes the block 9. The movable plate 8 pushes the block 9 to be re-engaged in the inside of the slot 5 under the elastic force of multiple springs 11 to lock the shell 4. In this way, the two shells 4 are fixed to the connecting frame 3 to form a protective shell for protecting the air compressor body 2, thereby realizing simple and fast maintenance and disassembly operations and improving work efficiency.
