Description

Technical Field

[0001] The utility model belongs to the technical field of seal ring guiding tools, and particularly relates to a seal ring assembly guiding tool. Background Art

[0002] A seal ring assembly guiding tool is a tool used to assemble a seal ring to a specified position. During the seal ring assembly process, since the inner diameter and outer diameter of the seal ring are generally close to the diameters of the shaft and the hole, it is very difficult to directly install it on the shaft or in the hole. Therefore, tools such as a guide sleeve are needed to guide the seal ring to the correct position. At the same time, in order to avoid damaging the seal ring during installation, auxiliary tools such as an installation disc can also be used to select a suitable position at the root of the shaft.

[0003] The existing seal ring guiding tools on the market have the following problems when applied:

[0004] 1. During the actual use of traditional seal ring guiding tools, several mounting holes are usually opened at the top of the plate body structure, and the threaded rod structure is installed in the corresponding mounting holes according to the diameter of the seal ring. However, the diameters of the seal rings are different, and the spacing cannot be adjusted according to the actual situation. Therefore, it is inconvenient to adjust the spacing during use.

[0005] 2. When most seal ring guiding tools are applied, a rod body structure is often used to clamp the rubber ring, and after it is installed in the corresponding notch, the rod body structure is released. However, during the process of clamping the seal ring, the rod body will rub against the surface of the seal ring, which easily leads to a decrease in sealing performance. Therefore, it cannot provide protection for the seal ring during application. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a seal ring assembly guiding tool to solve the technical problems raised in the background art.

[0007] To achieve the above purpose, the specific technical solution of the utility model is as follows: A seal ring assembly guiding tool includes a first plate body and a second plate body. The first plate body is connected to the second plate body through a rotating rod. Arc-shaped grooves are opened at the tops of the first plate body and the second plate body. A large threaded rod is embedded in the arc-shaped grooves. A connecting plate is arranged inside the large threaded rod. A slider is connected to the side of the connecting plate. The slider is slidably connected to the bottoms of the first plate body and the second plate body. A nut is externally threaded on the large threaded rod. A gasket is arranged at the bottom of the nut.

[0008] Preferably, anti-slip sleeves are sleeved on the outside of the rotating rod and the large threaded rod. Circular blocks are arranged at the bottoms of the rotating rod and the large threaded rod. An adhesive surface is arranged at the top of the circular block. The bottom of the anti-slip sleeve is connected to the adhesive surface by adhesion.

[0009] Preferably, sliding grooves are formed at the bottoms of the first plate body and the second plate body. The sliding grooves are symmetrically distributed, and sliders are embedded in the sliding grooves.

[0010] Preferably, threaded holes are formed at the bottoms of the large threaded rod and the rotating rod. A small threaded rod is fixedly connected to the top of the circular block, and the small threaded rod is threadedly connected to the threaded hole.

[0011] Preferably, extension handles are embedded in the first plate body and the second plate body, and elastic plates are arranged on the sides of the extension handles.

[0012] Preferably, positioning rods are arranged on the inner sides of the elastic plates. Positioning grooves are formed on the sides of the first plate body and the second plate body, and the positioning rods are inserted into the positioning grooves.

[0013] A sealing ring assembly guiding tool of the present utility model has the following advantages:

[0014] 1. For this sealing ring assembly guiding tool, by providing structures such as an arc-shaped groove, a large threaded rod, a slider, a connecting plate, a nut, etc. inside the first plate body, it can be directly adjusted according to the diameter of the sealing ring. After determining the diameter of the sealing ring, first reverse-rotate the nut outside the large threaded rod, and the large threaded rod moves to a suitable diameter size inside the arc-shaped groove. Then rotate the nut outside the large threaded rod again to fix the position. Since sliders and connecting plates are installed at the bottom, the situation of the large screw rod rotating can be avoided, so that the diameter of the sealing ring can be adjusted according to the actual situation during use;

[0015] 2. For this sealing ring assembly guiding tool, by installing structures such as a circular block, a small threaded rod, an adhesive surface, a non-slip sleeve, etc. outside the rotating rod and the large threaded rod, it can play a role in protecting the sealing ring during clamping. When it is necessary to clamp the sealing ring for installation, the non-slip sleeve is sleeved outside the rotating rod and the large threaded rod. Rotate the small threaded rod on the top of the circular block and install it at the bottoms of the rotating rod and the large threaded rod. Then tear off the transparent paper on the top of the adhesive surface and bond the non-slip sleeve to the top of the circular block. In this way, the sealing ring can be prevented from being worn during clamping, and the sealing ring can be protected during application. BRIEF DESCRIPTION OF THE DRAWINGS
