Description

Technical Field

[0001] This utility model relates to a hole plug, and more particularly to a working hole plug for an oil pan. Background Technology

[0002] The oil pan is a crucial component of the engine, located at the bottom, and plays a key role in engine lubrication, cooling, and protection. Some vehicle models have working holes in the oil pan to facilitate the installation of fasteners such as bolts, nuts, and pins for adjacent components, or to serve as channels for the flow of liquids and gases. When not in use, these working holes in the oil pan need to be sealed with plugs to prevent debris and dust from entering. Currently, threaded plugs are commonly used to seal the working holes, but these have drawbacks such as easy thread wear after long-term use and time-consuming disassembly. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an oil pan working hole plug, which is positioned by a clamp, and the clamp is installed in the clamp mounting hole of the outer shell. The clamp has good elasticity, making the plug easier to assemble and remove during use, and the clamp structure is not easily damaged.

[0004] The technical solution to the above technical problem is: an oil pan working hole plug, including an outer shell, the outer shell being a hollow irregular cylindrical part, the outer shell being a conical structure with one end larger than the other, the small end of the outer shell having at least two clip mounting holes, clips being provided in the clip mounting holes, longitudinal reinforcing ribs being connected inside the outer shell, and a transverse sealing plate being connected between the longitudinal reinforcing ribs and the outer shell.

[0005] Furthermore, the small end of the outer shell has 2 to 6 notches.

[0006] Furthermore, the cross-sectional shape of the clasp is a right trapezoid.

[0007] Furthermore, the transverse sealing plate is installed at a position between one-half and one-fifth of the height of the longitudinal reinforcing rib.

[0008] Furthermore, the angle β between the outer wall of the shell and the vertical line is 0.5 to 1.5°.

[0009] By adopting the above technical solution, this utility model has the following beneficial effects:

[0010] 1. This utility model features a latch mounting hole on the outer shell. The latch is positioned within this hole, with only its top end connecting to the outer shell. There are gaps between the bottom and sides of the latch and the outer shell, meaning only the top surface of the latch bears force, while the other surfaces are not. This design improves the latch's elasticity, making it easier to control the latch's tightening and loosening. It also makes the plug easier to assemble and remove during use. Compared to threaded connections, the latch connection structure is simpler and more time-saving to install and disassemble, less prone to damage, and has a longer service life.

[0011] 2. The outer shell of this utility model adopts a conical structure with one end larger than the other. The locking lug is located at the smaller end of the outer shell. After installation, the locking lug locks the oil pan to prevent the plug from coming out backward, while the conical structure of the outer shell prevents the plug from moving forward. That is, the plug of this utility model has good installation stability and is not easy to move without external force.

[0012] 3. The present invention has longitudinal reinforcing ribs inside the outer shell, which can not only strengthen the strength of the outer shell structure, but also be used as a gripping part during disassembly and assembly, making it easier to disassemble and assemble the plug.

[0013] The technical features of the oil pan working hole plug of this utility model will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0023] P1 - Oil pan working hole plug, P2 - Oil pan. Detailed Implementation

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Example 1: An oil pan working hole plug, such as Figures 1-5 As shown, the device includes an outer shell 1, which is a hollow, irregularly shaped cylindrical component. The outer shell has a tapered structure, wider at one end and narrower at the other. Two symmetrical mounting holes 12 are provided on the narrower end of the outer shell. A latch 2 is installed within each mounting hole, with its top end fixedly connected to the upper surface of the mounting hole 12. The bottom and sides of the latch are spaced apart from the mounting hole and do not contact it. The inner end face of the latch is approximately flush with the inner wall of the outer shell, while the outer end face protrudes beyond the outer shell. This means that only the top surface of the latch is stressed, while the other surfaces are not, making the latch structure more flexible, easier to use, increasing the number of reusable items, and extending its service life. A longitudinal reinforcing rib 4 is connected internally to the outer shell 1, and a transverse sealing plate 3 connects the longitudinal reinforcing rib 4 to the outer shell 1.

[0026] In this embodiment, the outer shell 1 is composed of an arc-shaped shell 13 and a V-shaped shell 14 formed by two flat plates, with the two sides of the V-shaped shell connected to the two sides of the arc-shaped shell. As a variation, the shape of the outer shell is adjusted and determined according to the shape of the working hole.

[0027] In this embodiment, the cross-sectional shape of the latch 2 is a right trapezoid, with the outer base corners rounded. Four notches 11 are provided on the small end of the outer shell, allowing for greater allowance for contraction at the small end and facilitating assembly and disassembly. As a variation, the cross-sectional shape and number of notches of the latch can be adjusted according to actual needs.

[0028] In this embodiment, the transverse sealing plate 3 is installed in the upper middle part of the outer casing. Besides sealing the casing to prevent debris and dust from entering the working hole, the transverse sealing plate also strengthens the casing. Considering the casing's strength, the installation position of the transverse sealing plate can be determined as needed. Generally, installing the transverse sealing plate between one-half and one-fifth the height of the longitudinal reinforcing rib provides better overall casing strength.

[0029] In this embodiment, the angle β between the outer wall of the shell and the vertical line is 1°. As a variation, the angle β between the outer wall and the vertical line can be adjusted according to the actual situation, generally from 0.5 to 1.5°.

[0030] The disassembly and assembly process of this utility model is as follows: Figure 8 As shown:

[0031] During assembly, simply hold the longitudinal reinforcing rib of the plug and push it in the assembly direction (i.e., towards the small end of the outer casing). Once pushed into place, the retaining clip will pop out and lock onto the oil pan, making the plug irremovable. This is the working state.

[0032] If you need to remove the plug when using the working hole, press the clips towards the center of the plug with both hands to retract the clips, and the plug can be removed without damage and can be reused.
