Description

Technical Field

[0001] This utility model relates to the field of air compressors, and in particular to a portable air compressor. Background Technology

[0002] Air compressors, as general-purpose machines that convert mechanical energy into gas pressure energy, are widely used in various fields such as industrial manufacturing, construction, mining, and automotive repair. Their core function is to provide a stable power source for various pneumatic equipment by compressing air. Among them, mobile air compressors, with their movable structural design, can flexibly adjust their location according to actual operational needs, effectively overcoming the limitations of stationary air compressors on operating scenarios. They demonstrate irreplaceable advantages in outdoor construction and mobile maintenance scenarios. One of the core components of a mobile air compressor is the air tank, whose main function is to store compressed high-pressure air. On the one hand, this balances the pressure fluctuations of the airflow output from the air compressor, ensuring a stable pressure air source for pneumatic equipment; on the other hand, it reduces the frequency of start-stopping of the air compressor, extending equipment life and reducing energy consumption. In practical applications, mobile air compressors need to be frequently moved between different work locations, and the transfer routes often involve complex environments at construction sites, corners in factory passageways, and rugged outdoor roads.

[0003] However, the air tanks of most mobile air compressors currently on the market are typically exposed, relying solely on the strength of their shells to withstand external impacts. During movement, the air tanks are highly susceptible to collisions with external objects due to road bumps, operational inertia, obstructed vision, or environmental obstacles (such as construction equipment, wall corners, and stacked materials). As pressure vessels storing high-pressure air, if the air tank suffers shell deformation, weld cracking, or surface damage due to collisions, it will not only directly affect its sealing and pressure-bearing capacity, leading to compressed air leakage and affecting the normal operating efficiency of the equipment, but may also cause safety hazards such as uncontrolled release of high-pressure air. In severe cases, it may even cause dangerous accidents such as tank rupture, threatening the personal safety of operators and surrounding facilities. In addition, the damage caused by collisions will shorten the service life of the air tank, increase equipment maintenance costs and downtime, and cause inconvenience and economic losses to production operations. Therefore, this application proposes a mobile air compressor to solve the above problems. Utility Model Content

[0004] The main objective of this invention is to provide a portable air compressor that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A portable air compressor includes an air tank with two fixed shafts symmetrically fixed at both ends. An anti-collision protection structure is movably fitted onto the air tank and rotatably mounted on both fixed shafts. The anti-collision protection structure consists of a mounting frame, internally threaded cylinders, mounting sleeves, fixing bolts, and strip-shaped rubber airbags. Four internally threaded cylinders are symmetrically fixed in pairs onto the mounting frame. Two mounting sleeves are symmetrically fixed onto the mounting frame, with the mounting sleeves positioned between the symmetrically arranged internally threaded cylinders. Four fixing bolts are installed inside the four internally threaded cylinders. Two strip-shaped rubber airbags are symmetrically fixed on the outer wall of the mounting frame.

[0007] Preferably, a rubber roller assembly is fixedly installed on the lower outer wall of the air tank, and an air compression assembly is fixedly installed on the upper wall of the air tank.

[0008] Preferably, the two fixed shafts are coaxial with the gas storage tank.

[0009] Preferably, the mounting frame on the anti-collision protection structure is movably fitted onto the gas storage tank, and the inner wall of the mounting frame is in contact with the outer wall of the gas storage tank.

[0010] Preferably, the mounting frame of the anti-collision protection structure has four first insertion holes symmetrically arranged in pairs on its wall. The first insertion holes penetrate the inside and outside of the mounting frame. The mounting frame also has two second insertion holes symmetrically arranged between the symmetrically arranged first insertion holes. The second insertion holes also penetrate the inside and outside of the mounting frame.

[0011] Preferably, the internally threaded cylinder on the anti-collision protection structure is fixedly inserted into the first insertion hole opened on the mounting frame, the mounting sleeve is fixedly inserted into the second insertion hole opened on the mounting frame, the mounting sleeve is simultaneously rotatably sleeved on the fixed shaft, and the inner end of the fixing bolt abuts against the outer wall of the gas storage tank.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By installing an anti-collision protection structure on the air tank, consisting of a mounting frame, internal threaded cylinder, mounting sleeve, fixing bolts, and strip-shaped rubber airbags, when the equipment encounters a collision during movement, the strip-shaped rubber airbags can first contact the obstacle, using the elastic properties of rubber to absorb the impact force, preventing the air tank from being directly impacted. This effectively protects the integrity of the air tank shell, preventing problems such as shell deformation and weld cracking caused by collisions, thereby ensuring the airtightness and pressure bearing capacity of the air tank, reducing the risk of compressed air leakage, lowering the probability of safety accidents, extending the service life of the air tank, and reducing maintenance costs and downtime. Furthermore, by installing fixing bolts at both ends of the air tank... The anti-collision protection structure is mounted on a fixed shaft via a mounting sleeve, allowing it to rotate and adjust flexibly around the shaft. When the equipment moves in different scenarios or faces potential collision risks from different directions, the structure can be rotated to adjust the orientation of the strip-shaped rubber airbags, ensuring that the most vulnerable areas are always protected by the airbags, thus enhancing the flexibility and specificity of the protection. Furthermore, the internal threaded cylinder, in conjunction with the fixing bolts, ensures the inner end of the anti-collision protection structure is firmly fixed to the outer wall of the air tank by tightening the bolts, preventing it from wobbling during equipment movement and ensuring stable protection.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a portable air compressor includes an air tank 1. Two fixed shafts 2 are symmetrically fixed at both ends of the air tank 1. An anti-collision protection structure 3 is movably fitted onto the air tank 1. The anti-collision protection structure 3 is rotatably mounted on both fixed shafts 2. The anti-collision protection structure 3 consists of a mounting frame 6, internally threaded cylinders 9, mounting sleeves 10, fixing bolts 11, and strip-shaped rubber airbags 12. Four internally threaded cylinders 9 are symmetrically fixed in pairs onto the mounting frame 6. Two mounting sleeves 10 are symmetrically fixed onto the mounting frame 6. The sleeve 10 is positioned between the symmetrically arranged internally threaded cylinders 9. Four fixing bolts 11 are installed inside the four internally threaded cylinders 9 respectively. Two strip-shaped rubber airbags 12 are symmetrically fixed to the outer wall of the mounting frame 6. By installing an anti-collision protection structure 3 on the air tank 1, consisting of the mounting frame 6, internally threaded cylinders 9, mounting sleeve 10, fixing bolts 11, and strip-shaped rubber airbags 12, when the equipment encounters a collision during movement, the strip-shaped rubber airbags 12 can first contact the obstacle, utilizing the elastic properties of the rubber material to absorb the impact. The anti-collision protection structure 3 is designed to prevent direct impact on the gas storage tank 1, thus protecting the shell of the gas storage tank 1 from deformation and weld cracking caused by collisions. This ensures the sealing and pressure resistance of the gas storage tank 1, reduces the risk of compressed air leakage, lowers the probability of safety accidents, and extends the service life of the gas storage tank 1, reducing maintenance costs and downtime. By setting fixed shafts 2 at both ends of the gas storage tank 1, and rotating the anti-collision protection structure 3 onto the fixed shafts 2 via the mounting sleeves 10, the anti-collision protection structure 3 can be flexibly adjusted around the fixed shafts 2. When the equipment moves in different scenarios or faces potential collision risks in different directions, the anti-collision protection structure 3 can be rotated according to actual needs to adjust the orientation of the strip rubber airbags 12, ensuring that the direction most susceptible to collision is always protected by the strip rubber airbags 12, improving the flexibility and specificity of the protection. Furthermore, the cooperation between the internal threaded cylinder 9 and the fixing bolts 11, by tightening the fixing bolts 11 so that its inner end is pressed against the outer wall of the gas storage tank 1, can achieve a stable fixation of the anti-collision protection structure 3, preventing it from shaking randomly during equipment movement and ensuring stable protection.

[0021] Specifically, a rubber roller assembly 4 is fixedly installed on the lower outer wall of the air tank 1, and an air compression assembly 5 is fixedly installed on the upper wall of the air tank 1. Two fixed shafts 2 are coaxial with the air tank 1. The mounting frame 6 on the anti-collision protection structure 3 is movably fitted onto the air tank 1, with the inner wall of the mounting frame 6 in contact with the outer wall of the air tank 1. Four first insertion holes 7 are symmetrically opened in pairs on the wall of the mounting frame 6 on the anti-collision protection structure 3, and the first insertion holes 7 penetrate the mounting frame 6 inside and out. Two second insertion holes 8 are symmetrically opened on the mounting frame 6, located between the symmetrically opened first insertion holes 7, and the second insertion holes 8 also penetrate the mounting frame 6 inside and out. The internally threaded cylinder 9 on the anti-collision protection structure 3 is fixedly inserted into the first insertion hole 7 opened on the mounting frame 6, and the mounting sleeve 10 is fixed. The mounting sleeve 10 is inserted into the second insertion hole 8 on the mounting frame 6 and simultaneously rotated and fitted onto the fixed shaft 2. The inner end of the fixing bolt 11 abuts against the outer wall of the gas tank 1. The inner wall of the mounting frame 6 contacts the outer wall of the gas tank 1. This contact method can stably fit the mounting frame 6 onto the gas tank 1, avoiding excessive displacement of the mounting frame 6 during equipment movement or collision prevention, and will not hinder the rotation of the mounting frame 6 around the fixed shaft 2. Since the mounting frame 6 is rotated and fitted onto the fixed shaft 2 through the mounting sleeve 10, and the fixed shaft 2 is coaxial with the gas tank 1, the contact between the inner wall of the mounting frame 6 and the outer wall of the gas tank 1 is only a slight fit without additional fastening constraints. Therefore, after loosening the fixing bolt 11, the mounting frame 6 can smoothly rotate around the fixed shaft 2 to adjust the orientation of the strip rubber airbag 12.

[0022] When using this portable air compressor, the equipment can be pushed to the work position via the rubber roller assembly 4, and then the air compression assembly 5 can be activated. This compresses outside air and sends it into the air tank 1 for storage. The air tank 1 balances airflow pressure fluctuations, providing a stable air source for pneumatic equipment. When the air tank 1 is about to encounter a collision during movement, the strip-shaped rubber airbag 12 on the anti-collision protection structure 3 will first contact the obstacle, using the elastic properties of the rubber material to absorb the impact force and prevent the air tank 1 from being directly impacted. Simultaneously, the mounting frame 6 supports the strip-shaped rubber airbag 12, effectively preventing deformation of the air tank 1's shell. Issues such as weld cracking; when it is necessary to rotate and adjust the anti-collision protection structure 3 on the fixed shaft 2, first loosen the four fixing bolts 11 so that the inner end of the fixing bolts 11 is separated from the outer wall of the air tank 1, and release the fixing restriction on the mounting frame 6. At this time, the mounting frame 6 can rotate around the fixed shaft 2 through the mounting sleeve 10. According to the direction of potential collision risk in the actual scenario, rotate the mounting frame 6 to adjust the orientation of the strip rubber airbag 12. After adjusting to the appropriate position, tighten the four fixing bolts 11 again so that the inner end of the fixing bolts 11 is pressed against the outer wall of the air tank 1 again, and fix the mounting frame 6 to complete the rotation adjustment of the anti-collision protection structure 3.

[0023] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
