Description

Technical Field

[0001] The utility model relates to the technical field of O-ring installation, in particular to a quick installation tool for an O-ring. Background Art

[0002] O-rings are a type of rubber seal with a circular cross section. Because of its O-shaped cross section, it is called an O-shaped rubber seal, also known as an O-ring. It first appeared in the mid-19th century, when it was used as a sealing element for steam engine cylinders. Because of its low price, simple manufacturing, reliable function, and simple installation requirements, O-rings are the most common mechanical design for sealing. O-rings withstand pressures of tens of megapascals (thousands of pounds). O-rings can be used in static applications, as well as in dynamic applications where there is relative motion between components, such as the shaft of a rotary pump and the piston of a hydraulic cylinder.

[0003] When installing a wind turbine, a large number of O-rings are usually required between its various components. Some O-rings are installed in remote locations (for example, inside a component or deep inside the unit). Therefore, it is often necessary to reach into the unit by hand and install it by tactile feel. This method is cumbersome and inefficient. Therefore, we propose a quick installation tool for O-rings. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. When a wind turbine is installed, a large number of O-rings are usually required to be installed between its various components. The installation positions of some O-rings are relatively remote (for example, inside a component or deeper in the unit). Therefore, it is often necessary to reach into the unit by hand and use tactile groping to install it during installation. This method is relatively cumbersome and inefficient.

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

[0006] A quick installation tool for an O-ring comprises a tubular shell, wherein a driving assembly is installed inside the tubular shell, wherein the driving assembly can drive a negative pressure assembly at the bottom to perform linear motion, wherein the negative pressure assembly can cause a connecting piece at the bottom to generate a negative pressure environment, wherein an installation assembly is provided at the bottom of the connecting piece, and wherein the installation assembly is used to place and install the O-ring.

[0007] As a preferred solution of the utility model, the driving assembly includes a telescopic rod, and the telescopic rod can drive the output connecting shaft to move.

[0008] As a preferred solution of the utility model, the telescopic rod is fixed inside the tubular housing, and the connecting shaft and the negative pressure assembly are fixed to each other.

[0009] The technical effect of adopting the above further solution is: the tubular shell fixes the telescopic fixing rod when the telescopic rod is driven.

[0010] As a preferred solution of the utility model, the negative pressure component includes a negative pressure pump, the bottom of the negative pressure pump is fixedly connected with a hard tube, and the hard tube is communicated with the negative pressure pump.

[0011] The technical effect of adopting the above further solution is that when the negative pressure pump is working, the inside of the hard catheter can be in a negative pressure state.

[0012] As a preferred solution of the utility model, the connecting member includes a sleeve, a cylindrical member is provided inside the sleeve, a connecting plate is fixedly connected between the cylindrical member and the sleeve, and a threaded body is also connected to the surrounding walls of the cylindrical member near the bottom.

[0013] The technical effect of adopting the above further solution is that the cylindrical member is connected and fixed to each other through the connecting plate and the sleeve, and the gap between the cylindrical member and the sleeve allows air to circulate.

[0014] As a preferred solution of the utility model, the installation component includes a component shell, a limit baffle is provided on the four walls of the component shell and near the top, a fixing column is also provided at the center of the component shell, and a connecting thread is provided on the inner wall of the component shell.

[0015] The technical effect of adopting the above further scheme is: the limit baffle can block and limit the O-ring to prevent it from being adsorbed into the inside of the connecting part. When the installed component is disassembled between the connecting part, it is only necessary to rotate the component shell, and then the connecting thread of the component shell and the threaded body on the cylindrical part will disengage from each other, thereby achieving the purpose of disassembly.

[0016] As a preferred solution of the utility model, the fixing column and the cylindrical member are connected to each other, and the installation assembly and the connecting member are communicated with each other.

[0017] The technical effect of adopting the above further solution is that the installation component and the connecting piece are connected to each other by a threaded body, so that they can be rotated, pulled out, disassembled and replaced.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] In the utility model, the driving component can drive the installation component to extend, so that the O-ring can be installed at a deeper level, and the installation component can be disassembled and replaced. It only needs to be rotated, and the installation component can be detached from the connecting piece, so that the installation component can be replaced according to different types of O-rings, thereby avoiding the problem that a large number of O-rings are usually required to be installed between the various components of the wind turbine when installing the wind turbine, and the installation position of some O-rings is relatively remote (for example, inside the component or deeper in the unit). Therefore, it is often necessary to reach into the unit by hand during installation and use tactile groping to install it. This method is relatively cumbersome and inefficient.
