Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment: As Figure 1 - Figure 6 shown, the present utility model provides a technical solution for an air compressor that is convenient for maintenance, including a chassis base 1. Four corners of the top of the chassis base 1 are fixedly connected with brackets 2. The tops of the four brackets 2 are fixedly connected with a chassis top cover 3. The bottom end inside the chassis top cover 3 is fixedly connected with a fixing plate 6. First chutes 4 are opened on both sides inside the chassis top cover 3. Second chutes 5 are opened inside the two first chutes 4. A moving plate 7 is arranged on the top of the fixing plate 6. A cooler 8 is arranged on the top of the moving plate 7. A protrusion is formed on the outer bottom of the cooler 8. A handrail 12 is fixedly connected to the front side of the top of the moving plate 7. A positioning plate 18 is arranged on the front side of the fixing plate 6. Sliding rods 10 are fixedly connected to the front ends of both sides of the moving plate 7. The two sliding rods 10 are respectively slidably connected inside the two second chutes 5. One side of one of the brackets 2 is fixedly connected with a limiting plate 20. A third chute 21 adapted to the second chute 5 is opened inside the limiting plate 20. The third chute 21 is communicated with the second chute 5. The sliding rod 10 moves inside the second chute 5 and the third chute 21, so that the cooler 8 can be moved to the side of the device, facilitating the maintenance work of the cooler 8 by workers. The rear ends of both sides of the moving plate 7 are rotatably connected with runners 9. The two runners 9 are respectively arranged inside the two first chutes 4.

[0025] As Figure 5 shown, a fixing groove 17 adapted to the protrusion is formed at the top of the inner wall of the moving plate 7, the protrusion is fitted with the fixing groove 17, a second clamping block 16 is fixedly connected to the rear side of the top of the moving plate 7, two first clamping blocks 13 are rotatably connected to the front side of the top of the moving plate 7, the bottoms of the two first clamping blocks 13 are both fitted with the protrusion, a pull rod 11 is fixedly connected to the front side of the bottom of the moving plate 7, a limiting rod 14 is slidably connected inside the armrest 12, springs 15 are fixedly connected to both sides of the top of the limiting rod 14, and one ends of the two springs 15 away from the limiting rod 14 are both fixedly connected to the armrest 12. Card slots are formed on both sides of the bottom of the limiting rod 14, and the two card slots are respectively adapted to the two first clamping blocks 13. The cooler 8 is fixed by the two first clamping blocks 13, which facilitates the disassembly and assembly during maintenance by workers.

[0026] As Figure 1 , Figure 2 , Figure 4 and Figure 6 shown, the top of the fixing plate 6 is in contact with the moving plate 7, the front side of the fixing plate 6 is fixedly connected to the positioning plate 18 by bolts, an air inlet pipe and an air outlet pipe are arranged on the front side of the cooler 8, through holes adapted to the air inlet pipe and the air outlet pipe are respectively formed inside the positioning plate 18, a top plate 19 is fixedly connected between the inner tops of the chassis top cover 3, the top of the positioning plate 18 is in contact with the top plate 19, a dust-proof plate 23 adapted to the cooler 8 is fixedly connected to the top of the chassis top cover 3, and baffles 22 are clamped between the four brackets 2.

[0027] When the present utility model is in use: During operation, the air compressor is installed on the top of the chassis base 1, and the fan of the cooler 8 is installed at the bottom of the fixing plate 6. When the cooler 8 needs to be cleaned, the worker disassembles the baffle 22 and the positioning plate 18 on the front side of the cooler 8 in sequence. When the runner 9 and the sliding rod 10 are respectively located at the rear sides of the first sliding groove 4 and the second sliding groove 5, the bottom of the moving plate 7 is in contact with the fixing plate 6, preventing the air flow from flowing out between the fixing plate 6 and the moving plate 7 when the fan is working, and reducing the heat dissipation effect.

[0028] On the rear sides of both the first sliding groove 4 and the second sliding groove 5, there are inclined upward slopes. After the worker removes the positioning plate 18, the worker pulls the pull rod 11 at the bottom of the moving plate 7 to move the moving plate 7 forward. At this time, the slopes provided on the rear sides of the first sliding groove 4 and the second sliding groove 5 cause the moving plate 7 to rise, so that the bottom of the moving plate 7 does not fit against the fixed plate 6, facilitating the removal of the moving plate 7. On the front sides of the first sliding groove 4 and the second sliding groove 5, there are inclined downward curved surfaces. An opening adapted to the sliding rod 10 is provided on one side of the top cover 3 of the chassis. When the sliding rod 10 moves to the front side of the second sliding groove 5, the sliding rod 10 enters the inside of the third sliding groove 21 along the inclined downward opening direction of the second sliding groove 5. At this time, the moving plate 7 starts to flip. When the sliding rod 10 moves to the bottom of the third sliding groove 21, the rotating wheel 9 is located in front of the first sliding groove 4, and the moving plate 7 completes the flipping. At this time, the cooler 8 faces the worker. Pull the limiting rod 14 to disengage the card slot of the limiting rod 14 from the first clamping block 13, and then rotate the first clamping block 13 so that the bottom of the first clamping block 13 does not contact the cooler 8. At this time, the cooler 8 can be taken out from the inside of the fixing groove 17 for cleaning. After cleaning, place the rear side of the cooler 8 on the curved surface of the second clamping block 16 inside the fixing groove 17, and rotate the first clamping block 13 to limit the front side of the cooler 8. The card slot of the limiting rod 14 closely adheres to the first clamping block 13 under the elastic force of the spring 15, so that the limiting rod 14 will not release the limit on the first clamping block 13 during work, preventing the cooler 8 from detaching from the top of the fixing groove 17. The cooler 8 is limited by the first clamping block 13 and the second clamping block 16, enabling the worker to quickly disassemble and install when maintaining the top cover 3 of the chassis.

[0029] After installation is completed, push the moving plate 7 to move. The rotating wheel 9 and the sliding rod 10 enter the rear sides of the first sliding groove 4 and the second sliding groove 5. At this time, the moving plate 7 returns to the top of the fixed plate 6 and fits against the fixed plate 6. Subsequently, align the positioning plate 18 with the intake pipe and the exhaust pipe of the cooler 8, and fix the cooler 8 to the fixed plate 6. The cooler 8 limits the moving plate 7, making the moving plate 7 unable to move. Through the arrangement of the first sliding groove 4 and the second sliding groove 5, the cooler 8 can be moved from the top of the top cover 3 of the chassis to one side of the device, enabling the worker not to disassemble the cooler 8 on the top of the top cover 3 of the chassis, improving the disassembly efficiency, and facilitating the worker to maintain and disassemble the cooler 8.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
