[0028] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other.

[0030] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "fixing," "connection," "linking," "located in," and "located in" should be interpreted broadly. For example, they can refer to a fixed connection (or an integral structure), a detachable connection, a mechanical connection, a chemical connection, a direct connection, or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Some embodiments of this utility model disclose an auxiliary tool for installing sealing rings. For example, sealing ring 4 is the sealing ring of a high-pressure oil pump. As one of the core components in engines and mechanical equipment, the high-pressure oil pump plays an important functional role. Its main task is to pressurize fuel or lubricating oil and deliver it to various parts inside the engine through the oil pump system to ensure the normal operation of the equipment. The sealing ring 4 of the high-pressure oil pump plays a crucial role in this process, effectively preventing oil leakage and ensuring the sealing performance and working efficiency of the system.

[0033] The sealing ring 4 of a high-pressure oil pump typically has a certain inner diameter and thickness, and requires precise alignment during installation. To ensure the normal operation of the oil pump, the sealing ring 4 needs to be securely seated in the pump's mounting groove to prevent problems such as oil leakage or poor sealing due to improper installation. Therefore, the installation of the sealing ring 4 requires extreme precision and efficiency. The high-pressure oil pump sealing ring described here is merely an example and is not intended to limit this application; other sealing rings that need to be installed in mounting grooves on the inner wall of the channel can also be used.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the sealing ring installation auxiliary tool includes an installation body 1, two action parts 2, and a positioning assembly 3, as detailed below:

[0035] The mounting body 1 includes a first end face 11 and a second end face 12 that are opposite to each other in the height direction H, and two slots 13 that extend from the first end face 11 to the second end face 12.

[0036] Two actuators 2 are rotatably installed in two slots 13, that is, the two actuators 2 rotate about the height direction H of the mounting body 1. The actuators 2 include an operating part 21 exposed on the first end face 11 and an action part 22 exposed on the second end face 12.

[0037] The positioning component 3 is disposed on the second end face 12. The positioning component 3 includes a slot 321 for holding the sealing ring 4 therein, and two working parts 22 for acting on the inner ring side of the sealing ring 4 and bending the sealing ring 4 by rotation are located on both sides of the positioning component 3.

[0038] The sealing ring installation auxiliary tool can hold the sealing ring 4 in the slot 321, and can act on the inner ring side of the sealing ring 4 through the action part 22 and bend the sealing ring 4 when rotating, thereby solving the problem that the sealing ring 4 is easy to slip out of the tool during bending, and improving installation efficiency and reliability.

[0039] In actual installation, the sealing ring 4 is placed horizontally, with the opening of the sealing ring 4 facing the same direction as the height H of the mounting body 1. The operator rotates the operating part 21 to rotate the actuating part 22, so that the actuating part 22 is positioned in front of the positioning assembly 3 at A. In the first position, the actuating part 22 is placed on the inner ring side of the sealing ring 4, and the sealing ring 4 is secured in the slot 321, i.e. Figure 1 and Figure 2 As shown. Next, the operator rotates the operating part 21 to drive the actuating part 22 to rotate towards the rear B of the positioning assembly 3 (i.e., as shown). Figure 1 (As shown by the rotating arrow), rotate to the second position. During the rotation, the actuating part 22 acts on both sides of the inner ring of the sealing ring 4 and bends the sealing ring 4 from both sides towards the rear B of the positioning component 3, using the groove 321 as a fixed point. The cooperation between the groove 321 and the actuating part 22 facilitates the operator to bend and deform the sealing ring 4, while preventing the sealing ring 4 from slipping out, so as to facilitate the subsequent installation of the sealing ring 4. Then, the operator grips the operating part 21 and aligns the end of the bent sealing ring 4 that is not acted on by the actuating part 22 into the installation groove on the inner wall of the channel. Next, the operator rotates the operating part 21 in the opposite direction to drive the actuating part 22 to rotate towards the front A of the positioning component 3 and rotate to the first position, so that the sealing ring 4 returns to its original shape. Finally, the operator removes the sealing ring 4 from the groove 321 and manually aligns the sealing ring 4 completely into the installation groove on the inner wall of the channel to complete the installation of the sealing ring 4. The whole process is simple to operate, has high installation consistency, and a high pass rate.

[0040] In some embodiments, such as Figure 3 As shown, to address the issue of insufficient adaptability of a single tool to sealing rings 4 of varying thicknesses, the positioning assembly 3 includes a connector 31 and a positioning component 32. The connector 31 is fixedly connected to the second end face 12, and the positioning component 32 is connected to the connector 31 via a detachable connection structure 33. The positioning component 32 has a slot 321, the width of which is adapted to the thickness of the sealing ring 4. The thickness of the sealing ring 4 is generally between 2 mm and 6 mm, therefore the width of the slot 321 is between 2 mm and 6 mm. Through the modular design of the positioning component 32 and the multiple specifications of the slot 321, operators can select the corresponding positioning component 32 for installation according to the thickness of the sealing ring 4, achieving precise fixing of the sealing ring 4.

[0041] In some embodiments, such as Figure 3 As shown, for convenient and quick operation, the detachable connection structure 33 includes an internally threaded grooved cylinder 331 and a lead screw 332. The lead screw 332 is connected to the internally threaded grooved cylinder 331. One of the positioning member 32 and the connecting member 31 is provided with the internally threaded grooved cylinder 331, and the other is provided with the lead screw 332.

[0042] In some embodiments, in order to reduce the weight of the tool, the positioning element 32 is a positioning post made of aluminum alloy or plastic. The aluminum alloy and plastic materials mentioned here are just examples and are not intended to limit this application. Other lightweight materials may also be used.

[0043] In some embodiments, such as Figure 3 As shown, the slot 321 is located at the end of the positioning member 32 away from the connector 31. The positioning component 3 (specifically the positioning member 32) also includes two spaced-apart opposing first walls 322 and second walls 323 to form the slot 321. The first walls 322 and the second walls 323 extend along the height direction H of the mounting body 1, respectively.

[0044] In some embodiments, such as Figure 1 and Figure 2 As shown, the two actuating parts 22 have a first position and a second position. When in the first position, the two actuating parts 22 are respectively located on the side of the first wall 322, so as to be placed on the inner ring side of the sealing ring 4. When the two actuating parts 22 are rotated to the second position, the two actuating parts 22 are respectively located on the side of the second wall 323, so as to act on the inner ring side of the sealing ring 4 and bend the sealing ring 4.

[0045] In some embodiments, such as Figure 1 and Figure 2 As shown, the two functional parts 22 extend in a direction away from each other (bending or horizontally) for a period of time and then extend in a direction away from the second end face 12 (vertical or bending); or, the two functional parts 22 gradually bend and extend in a direction away from each other and in a direction away from the second end face 12.

[0046] And / or, in some embodiments, the two operating parts 21 extend in a direction away from each other (bending or horizontally) for a period of time and then extend in a direction away from the first end face 11 (vertical or bending); or, the two operating parts 21 gradually bend and extend in a direction away from each other and in a direction away from the first end face 11.

[0047] It should be noted that the vertical direction refers to the height direction H of the mounting body 1, and the horizontal direction refers to the direction perpendicular to the height direction H of the mounting body 1.

[0048] In some embodiments, to enhance operational stability, the operating part 21 includes a ring hole, and / or the operating part 21 (e.g., the ring hole) is provided with an anti-slip structure. The anti-slip structure is an anti-slip texture or an anti-slip layer on the surface of the operating part 21. For example, the anti-slip texture is a mesh pattern, and the anti-slip layer is a rubber layer. The mesh pattern and rubber layer here are just examples and are not intended to limit this application. Other types are also possible.

[0049] In some embodiments, in order to assist in fixing the rotating actuating member 2, one operating part 21 is a magnet, the other operating part 21 is a metal body, or the two operating parts 21 are magnets that attract each other, so as to achieve magnetic attraction-assisted fixing when they rotate and move closer to each other.

[0050] In some embodiments, the mounting body 1 is an elliptical or circular structure to facilitate gripping by the operator.

[0051] In some embodiments, in order to enhance the fixing effect of the sealing ring 4, the groove 321 is a rectangular groove, a U-shaped groove or a V-shaped groove. The rectangular groove, U-shaped groove and V-shaped groove here are just examples and are not intended to limit this application. Other grooves are also possible.

[0052] It is understood that the above embodiments only illustrate some implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can freely combine the above embodiments or technical features without departing from the concept of this utility model, and can also make several modifications and improvements, all of which fall within the protection scope of this utility model. That is, the embodiments described "in some embodiments" can be freely combined with any of the preceding and following embodiments.
