In addition, the contact area between the lower end of the air compressor and the ground is small, and long-term vibrations can easily cause damage to the ground, and the noise will also affect the mental state of the operating staff. Utility Model Content

[0004] The utility model aims to provide a novel air compressor. The utility model aims at the problems in the prior art of loss of compressor body life due to vibration, high noise pollution and easy damage to the ground, and provides a shock absorbing device for solving the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A novel air compressor comprises a compressor body, a loading platform, and four shock absorbing devices; the compressor body is fixed to the upper end of the loading platform, and the compressor body is used to complete the process of air compression and storage; the lower end of the loading platform is hollow inside, and the four shock absorbing devices are respectively arranged at the four corners of the loading platform, and are used to suspend the loading platform; the shock absorbing device comprises a force plate, a connecting rod, a piston, an inner cylinder, an outer cylinder, a spring and a connecting ring; the upper end of the force plate is fixedly connected to the loading platform; the inner cylinder is sleeved in the outer cylinder at intervals; the upper end of the outer cylinder is connected to the connecting ring The upper side of the outer wall is fixedly connected, and the upper end of the inner cylinder is fixedly connected to the lower side of the outer wall of the connecting ring; the upper end of the connecting rod is fixedly connected to the force-bearing plate, and the lower end of the connecting rod passes through the connecting ring and is fixedly connected to the piston; the piston is slidably sleeved in the inner cylinder; the spring is sleeved on the connecting rod between the force-bearing plate and the outer cylinder; a cavity exists between the outer wall of the inner cylinder and the inner wall of the outer cylinder; a plurality of upper throttling holes are provided on the piston, and a plurality of lower throttling holes are provided at the bottom of the inner cylinder; hydraulic oil is contained in the inner cylinder below the piston; and an air cavity is in the outer cylinder above the hydraulic oil level.

[0007] Furthermore, a sealing ring is provided at the upper end of the connecting ring; the sealing ring is tightly clamped between the connecting rod and the outer tube, and the sealing ring improves the sealing between the connecting rod and the outer tube.

[0008] Furthermore, the four outer cylinders are fixedly connected by four fixing columns, and the outer cylinders and the fixing columns form a rectangle.

[0009] Furthermore, a base is fixed to the upper end of the loading platform; an arc-shaped groove is provided at the upper end of the base; a plurality of lower locking holes are respectively provided at the upper ends of the base on both sides of the groove; mounting plates are respectively fixed to both sides of the compressor body; a plurality of upper locking holes are provided on the mounting plate; the lower end of the compressor body is inserted into the groove; the mounting plate is erected on the base, a locking bolt passes through the upper locking hole and its lower end is threadedly connected to the lower locking hole to lock the mounting plate to the base.

[0010] Furthermore, a base is sleeved on the outer lower end of the outer cylinder.

[0011] Furthermore, the base is made of rubber.

[0012] After adopting the above technical solution, the utility model has the following beneficial effects:

[0013] 1. The utility model effectively absorbs and consumes the vibration energy generated during the operation of the air compressor by designing a unique shock absorbing device, significantly reduces the vibration amplitude of the compressor body, thereby extending the service life of the air compressor. At the same time, the shock absorbing device forms an efficient damping system through the mutual cooperation of hydraulic oil and throttle holes. When the shock absorbing device is compressed, the hydraulic oil flows to the top of the piston through the upper throttle hole on the piston. Due to the small aperture, the flow speed of the oil is slowed down, thereby generating a damping force and reducing vibration. In addition, when the hydraulic oil level rises, the air pressure in the air cavity between the outer cylinder and the inner cylinder increases, and a part of the vibration energy of the compressor is converted into the energy of air compression, which plays a role similar to a spring and achieves a shock absorbing effect. When the shock absorbing device rebounds, the hydraulic oil returns through the upper throttle hole, and the flow speed is slow, further reducing vibration. The shock absorbing device effectively suppresses the generation and propagation of vibration noise, greatly reduces noise pollution, and improves the working environment.

[0014] 2. The utility model provides a spring on the connecting rod at the upper end of the outer cylinder. The spring can share a part of the vibration force generated by the upper compressor body during the stretching and compression process, thus playing a buffering role. Under the joint action of the hydraulic oil, the air cavity and the spring, the effect of efficient vibration reduction and noise reduction is achieved.

[0015] 3. The utility model provides a sealing ring at the upper end of the connecting ring, and the two ends of the sealing ring are tightly fitted with the inner wall of the upper end of the outer tube. The sealing ring ensures the sealing of the gas in the cavity and the hydraulic oil will not leak, thereby ensuring the stability of the shock absorption effect.

[0016] 4. The utility model is provided with a base, and the arc-shaped groove on the base is used to place the compressor body. The arc-shaped groove increases the force-bearing area between the compressor body and the loading platform, so that the vibration energy generated by the compressor body can be more evenly dispersed on the base. Since the bottom of the base is fixedly connected to the upper end of the loading platform, the force distribution on the upper end of the loading platform is uniform, and the lower end of the loading platform is connected to the upper end of the force plate, so that the vibration energy is evenly dispersed to the shock-absorbing devices in the four corners; fixing the compressor body on the base can effectively position and support the compressor body, ensuring its stability and safety during operation.

[0017] 5. The base of the shock absorbing device of the utility model is made of rubber material. The rubber base contacts the ground, which not only enhances the shock absorbing performance, but also reduces the noise caused by hard contact and increases the force bearing area, reducing damage to the ground, so that the shock absorption and noise reduction effects are further improved.

[0018] 6. Fixed columns are arranged between the shock absorbing devices of the utility model so that the shock absorbing devices can support each other and enhance the stability of the shock absorbing devices. BRIEF DESCRIPTION OF THE DRAWINGS
