Description

Technical Field

[0001] The utility model relates to a plastic oil tank for a small hydraulic system, which is used for placing hydraulic oil and components such as a hydraulic pump core, and belongs to the field of hydraulic accessories in a hydraulic system. Background Art

[0002] With the widespread application of hydraulic tools in various fields, users have an increasingly urgent need for easy carrying. Traditional oil tanks are often made of welded steel, which is heavy and inconvenient to carry and operate. Lightweight design is the key to solving this problem. By using lightweight materials, such as ABS engineering plastics, the weight of the oil tank can be significantly reduced, the portability can be improved, and the user's demand for efficient portable tools in modern society can be met.

[0003] In the prior art, the oil tank of a small hydraulic system is often made of welded steel.

[0004] Firstly, the weight of the steel welded hydraulic oil tank is relatively large, especially for hydraulic tools or small hydraulic systems that need to be moved. The heavy tank makes it inconvenient to carry, affecting the flexibility and efficiency of the work.

[0005] Secondly, poor welding quality is one of the common problems of steel welded hydraulic oil tanks, which can easily lead to oil leakage in the oil tank. Weak welding or weld quality problems will cause the oil tank to be affected by vibration during the operation of the hydraulic system, thus causing the risk of oil leakage.

[0006] However, the liquid level gauge of the existing traditional steel oil tank is usually installed on the surface of the oil tank, which is vulnerable to external collisions and bumps, causing damage to the liquid level gauge, which may in turn cause leakage problems.

[0007] Finally, existing traditional steel oil tank seals usually use flat gaskets, which are complicated to install and prone to oil leakage, resulting in poor sealing performance, thus affecting the stability and safety of the hydraulic system. Summary of the invention

[0008] The technical problem to be solved by the utility model is to provide an oil tank with light overall weight, a built-in liquid level gauge and safe and convenient replacement of sealing parts.

[0009] In order to solve the above technical problems, the utility model provides a lightweight hydraulic oil tank, which includes a tank body, the top surface of the tank body is provided with a groove for installing a tank sealing ring, the side of the tank body is provided with a groove recessed in the tank body for installing a liquid level gauge, the bottom of the liquid level gauge passes through the bottom of the tank body and is connected to the liquid level gauge mounting block, and the liquid level gauge mounting block is embedded in the bottom of the tank body.

[0010] Preferably, the fuel tank body is made of ABS, which has the characteristics of toughness, hardness and rigidity.

[0011] Preferably, the liquid level gauge mounting block is connected and fixed to the oil tank body by screws.

[0012] Preferably, a liquid level gauge sealing ring is provided between the liquid level gauge and the bottom of the oil tank body.

[0013] Preferably, the liquid level meter is connected to the liquid level meter mounting block via a liquid level meter connecting rod, and both ends of the liquid level meter connecting rod are respectively inserted into the bottom end of the liquid level meter and the mounting hole of the liquid level meter mounting block.

[0014] The hydraulic oil tank involved in the utility model has a tank body with a reserved tank sealing ring installation groove on the top surface; compared with the sealing form of a flat sealing gasket adopted in the prior art, the tank sealing ring adopted in the utility model has the advantages of repeated installation, simple installation and good anti-leakage sealing performance.

[0015] The liquid level gauge of the hydraulic oil tank involved in the utility model is installed in a recessed position on the side of the oil tank body, which can reduce the risk of the liquid level gauge being damaged by impact due to being exposed to the outside of the oil tank body during daily use. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the present invention more obvious and easy to understand, preferred embodiments are described in detail as follows in conjunction with the accompanying drawings.

[0018] Example

[0019] like Figure 1 As shown, a lightweight hydraulic oil tank provided by the utility model includes a tank body 1, the top surface of the tank body 1 is provided with a groove for installing the tank sealing ring 2, the side of the tank body 1 is provided with a groove recessed in the tank body 1 for installing the liquid level gauge 6, the bottom of the liquid level gauge 6 passes through the bottom of the tank body 1 and is connected with the liquid level gauge mounting block 4, and the liquid level gauge mounting block 4 is embedded in the bottom of the tank body 1.

[0020] The liquid level gauge mounting block 4 is connected and fixed to the oil tank body 1 by screws 7. A liquid level gauge sealing ring 3 is provided between the liquid level gauge 6 and the bottom of the oil tank body 1. The liquid level gauge 6 is connected to the liquid level gauge mounting block 4 by a liquid level gauge connecting rod 5, and the two ends of the liquid level gauge connecting rod 5 are respectively inserted into the bottom end of the liquid level gauge 6 and the mounting hole of the liquid level gauge mounting block 4.
