[0002] Compressors are a common mechanical device in many industrial applications and vehicle systems, and they are indispensable, especially in the process of air compression or cooling. In order to ensure stable operation, suppress noise, and improve overall efficiency, compressors usually need to be firmly connected to the supporting structure through a sturdy base. In the field of traditional cab compressor base technology, the fixing methods of the compressor and the base mainly include the use of bolts, welding or embedded rubber shock absorbers.

[0003] Specifically, the bolt fixing method includes presetting holes at the bottom of the compressor to correspond to the holes on the base, and using bolts to fix the compressor to the base. However, uneven road surfaces, potholes, bumps and uneven roads can cause vibrations in the cab. As the vibrations continue to affect the cab, the bolts may gradually become loose, causing the connection between the compressor and the base to become unstable, which may cause the entire compressor to shake, increase noise during operation, and may also endanger safety.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] refer to Figure 1-9 A cab compressor base includes a base plate 1, a plurality of supporting legs 101 are provided at the bottom of the base plate 1, a plurality of threaded holes 802 are provided at the top of the base plate 1, a connecting box 2 is provided between the supporting legs 101 at the bottom of the base plate 1, a plurality of fixing grooves 102 are provided on the top of the connecting box 2 near the threaded holes 802, a fixing mechanism for fixing bolts 801 is provided in each fixing groove 102, a transmission mechanism for driving the fixing mechanism to fix the bolts 801 is provided inside the connecting box 2, each fixing mechanism is linked with the transmission mechanism, the staff only needs to move the transmission mechanism, and the plurality of fixing mechanisms will automatically fix the bolts 801, which is convenient to operate.

[0028] In this embodiment, the transmission mechanism includes a first bevel gear 201, a second bevel gear 202, a first rotating shaft 203, a second rotating shaft 204, and a spur gear 205. The first rotating shaft 203 is arranged inside the connection box 2, the first bevel gear 201 is arranged at one end of the first rotating shaft 203 close to the bottom of the connection box 2, the second bevel gear 202 is meshed with the first bevel gear 201, the second rotating shaft 204 is arranged at one end of the second bevel gear 202 away from the first bevel gear 201, the second rotating shaft 204 passes through the connection box 2 and the side of the support leg 101, and extends to the outside of the support leg 101, a partition plate 206 is provided at one end of the connection box 2 away from the first bevel gear 201, the first rotating shaft 203 passes through the partition plate 206, and extends to the top of the partition plate 206, the spur gear 205 is arranged at one end of the first rotating shaft 203 away from the first bevel gear 201, and the spur gear 205 is linked with the transmission mechanism;

[0029] There are at least three fixed grooves 102, and the three fixed grooves 102 are circumferentially arranged with the spur gear 205 as the center. At the same time, there are also three fixing mechanisms, which are respectively arranged on the inner walls of the fixed groove 102. The fixing mechanisms include a fixed block 207, a fixed rack 208, an elastic member 803, and a locking assembly. The fixed rack 208 is arranged on the top of the partition plate 206 and meshes with the spur gear 205. A sliding block 209 is arranged on the top of the fixed rack 208. The sliding block 209 is tilted downward on the side away from the spur gear 205 and is provided with a first inclined surface 2091. The fixed block 207 is arranged on the top of the sliding block 209 and is slidably connected to the inner wall of the fixed groove 102. A connecting block 210 is arranged at the bottom of the fixed block 207. A second inclined surface 211 slidably connected to the first inclined surface 2091 is provided on the side of the connecting block 210 close to the first inclined surface 2091. One end of the elastic member 803 abuts against the connecting block 210, and the other end of the elastic member 803 abuts against the connecting box 2.

[0030] A rotating block 215 is provided at one end of the second rotating shaft 204 away from the second bevel gear 202. The surface of the rotating block 215 is provided with anti-skid patterns. The rotating block 215 can help the staff to obtain a larger torque, making it convenient for the staff to rotate the second rotating shaft 204. The anti-skid patterns can increase the contact area between the staff and the rotating block 215, preventing the staff from slipping due to wet hands.

[0031] When the staff wants to prevent the bolt 801 from loosening, they only need to rotate the rotating block 215 clockwise, and the rotating block 215 will drive the second bevel gear 202 to rotate through the second rotating shaft 204. Since the second bevel gear 202 is meshed with the first bevel gear 201, the first bevel gear 201 will rotate driven by the second bevel gear 202, and the first bevel gear 201 will drive the spur gear 205 to rotate through the first rotating shaft 203. Since the spur gear 205 is meshed with the fixed rack 208, when the spur gear 205 rotates, the rack will move downward, thereby driving the sliding block 209 Move downward, since the first inclined surface 2091 is slidingly connected to the second inclined surface 211, when the sliding block 209 moves downward, the first inclined surface 2091 will drive the second inclined surface 211 of the connecting block 210 to move, and since the fixing groove 102 limits the freedom of the fixing block 207 to move downward, the supporting block will move in the fixing groove 102, thereby fixing the bolt 801. In order to improve the fixing effect, the side of the fixing block 207 away from the spur gear 205 is an arc-shaped structure. The arc-shaped structure of the fixing block 207 can increase the contact area with the bolt 801, thereby improving the fixing effect.

[0032] In this embodiment, the fixed rack 208 is slidably connected to the top of the partition plate 206, and a plurality of guide grooves 213 are provided on the top of the partition plate 206. A guide block 214 is provided at the bottom of the fixed rack 208. The guide block 214 is slidably connected to the inner wall of the guide groove 213. The guide block 214 and the guide groove 213 limit the freedom of the fixed rack 208, so that the fixed rack 208 can only move along the inner wall of the guide groove 213, thereby improving the stability and accuracy of the movement. When the spur gear 205 rotates, it will drive the fixed rack 208 to move, thereby driving the guide block 214 to be slidably connected to the inner wall of the guide groove 213.

[0033] refer to Figure 4In order to increase the self-locking property of the transmission mechanism, the locking assembly includes a locking block 901. A slide groove 9 is provided inside the support leg 101. The locking block 901 is provided in the slide groove 9. One end of the locking block 901 abuts against the second rotating shaft 204. A locking inclined surface 902 is provided at the other end of the locking block 901. A locking screw 903 is threadedly connected to one side of the support leg 101 close to the locking inclined surface 902. When the staff fixes the bolt 801, the locking screw 903 can be rotated to tighten the locking screw. The nail 903 will squeeze the locking bevel 902, thereby moving the locking block 901 towards the direction close to the second rotating shaft 204, and then fixing the second rotating shaft 204, thereby locking the transmission mechanism. In order to facilitate the locking screw 903 to squeeze the locking bevel 902, a rounded corner is set at one end of the locking screw 903 close to the locking bevel 902. The rounded corner reduces the contact area with the locking bevel 902, thereby making it easier for the locking screw 903 to slide on the locking bevel 902.

[0034] Working principle: When the staff wants to prevent the bolt 801 from loosening, they only need to rotate the rotating block 215 clockwise. The rotating block 215 will drive the second bevel gear 202 to rotate through the second rotating shaft 204. Since the second bevel gear 202 is meshed with the first bevel gear 201, the first bevel gear 201 will rotate under the drive of the second bevel gear 202. The first bevel gear 201 will drive the spur gear 205 to rotate through the first rotating shaft 203. Since the spur gear 205 is meshed with the fixed rack 208, when the spur gear 205 rotates, the rack will move downward, thereby driving the sliding block 209 downward. Movement, since the first inclined surface 2091 is slidably connected with the second inclined surface 211, when the sliding block 209 moves downward, the first inclined surface 2091 will drive the second inclined surface 211 of the connecting block 210 to move, and since the fixing groove 102 limits the freedom of the fixing block 207 to move downward, the supporting block will move in the fixing groove 102, thereby fixing the bolt 801. In order to reduce the friction between the fixing block 207 and the fixing groove 102, a plurality of balls 212 are provided on both sides of each fixing groove 102. The balls 212 can reduce the friction between the fixing block 207 and the inner wall of the fixing groove 102, thereby improving the service life;

[0035] When the staff needs to remove the compressor 8, loosen the locking screw 903 to allow the second rotating shaft 204 to rotate counterclockwise. When the second rotating shaft 204 rotates counterclockwise, the spur gear 205 will drive the fixed rack 208 to move upward, thereby driving the sliding block 209 to move upward. Under the action of the resetting of the elastic member 803, the connecting block 210 will always be in contact with the sliding block 209, thereby making the fixed block 207 disengage from the bolt 801, making it easier for the staff to disassemble the compressor 8.

[0036] The above are only preferred embodiments of the present invention and are 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.
