[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figure 1 and Figure 2 This is the first embodiment of the present invention, which provides an observation hole cover, including...

[0025] The extension 7 is provided with a boss 4. The extension 7 provides a stable mounting base for the boss 4, ensuring that the boss 4 is not easily loosened under engine vibration. The boss 4 has a communication port 41 inside that corresponds to the observation hole. The communication port 41 inside the boss 4 corresponds to the observation hole, which not only ensures the accuracy of the observation path, but also enhances the structural strength around the communication port 41 through the protruding structure of the boss 4.

[0026] The sealing component includes a fixing handle 5, which facilitates the operator's gripping and disassembly of the sealing component, improving operational convenience. A plug 52, located at the bottom of the fixing handle 5, can penetrate the connecting port 41. A sealing sleeve 6, located on the plug 52 and tightly fitted to the connecting port 41, provides basic sealing by the plug 52 penetrating the connecting port 41. The sealing sleeve 6, tightly fitted to the connecting port 41, significantly enhances the sealing performance, preventing dust, moisture, and other impurities from entering the engine. A fixing post 51, located at the bottom of the fixing handle 5, has a fixing groove 42 on the boss 4 for the fixing post 51 to be inserted. The fixing post 51 is inserted into the fixing groove 42 to form a double fixation, preventing the sealing component from falling off due to vibration during engine operation and improving structural stability.

[0027] In this embodiment, preferably, it also includes a plurality of rubber strips 8 disposed on the inner side of the fixing groove 42, and the plurality of rubber strips 8 can be tightly fitted with the fixing post 51. The rubber strips 8 use their own elasticity to fit tightly with the fixing post 51, which on the one hand enhances the connection tightness between the fixing post 51 and the fixing groove 42 and further prevents the sealing component from loosening; on the other hand, the rubber strips 8 can buffer the vibration friction between the fixing post 51 and the fixing groove 42, reduce component wear, and at the same time play a certain sealing auxiliary role.

[0028] In this embodiment, preferably, the fixing handle 5 has an elliptical structure, and the plug 52 and the fixing handle 5 are an integral structure. The elliptical structure of the fixing handle 5 is more ergonomic, making it easier to exert force when gripping, and it is not easy to slip out of the hand. The integral structure of the plug 52 and the fixing handle 5 eliminates the connection gap between the two, improves the overall strength of the sealing component, avoids sealing failure due to loose connection, and at the same time reduces assembly steps and reduces production costs.

[0029] In this embodiment, preferably, it also includes a hole cover body 1 disposed on the extension 7 and a support platform 3 disposed between the hole cover body 1 and the extension 7. The hole cover body 1 serves as the main sealing structure of the observation hole, achieving comprehensive protection of the observation hole. The support platform 3 connects the hole cover body 1 and the extension 7, which not only enhances the stability of the connection between the two, but also disperses the pressure on the hole cover body 1 by increasing the contact area, thus avoiding deformation due to excessive local stress.

[0030] In this embodiment, preferably, the corners of the cover body 1 are arc-shaped. The arc-shaped corners eliminate sharp edges, reducing the risk of operators being scratched during installation and maintenance. At the same time, it reduces stress concentration and improves the structural durability of the cover body 1. The cover body 1 has multiple fixing holes 11 inside. The multiple fixing holes 11 facilitate the secure installation of the cover body 1 on the engine block, ensuring the sealing and stability after installation and adapting to the needs of different installation positions.

[0031] Example 2

[0032] Please see Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment, but differs in that:

[0033] A reinforcing frame 2 is installed on the support platform 3, and one end of the reinforcing frame 2 is flush with one end of the hole cover body 1. The reinforcing frame 2 further strengthens the connection between the support platform 3 and the hole cover body 1, and improves the overall structure's resistance to deformation. The fact that one end of the frame is flush with the hole cover body 1 ensures the flatness of the hole cover's appearance and avoids damage caused by bumps and knocks caused by protruding structures. The reinforcing frame 2 has reinforcing ribs inside, which significantly improves the structural strength of the reinforcing frame 2 itself, making it less prone to bending and deformation when subjected to external forces. The reinforcing frame 2 and the support platform 3 are connected by screws. The screw connection method facilitates the disassembly and maintenance of the reinforcing frame 2, while ensuring the reliability of the connection, which is suitable for the repeated maintenance needs of engine components.

[0034] The working principle and usage process of this utility model: With the help of multiple fixing holes 11 inside the hole cover body 1, bolts and other connecting parts are used to fix the hole cover body 1 to the corresponding position of the engine body, ensuring that the hole cover body 1 fits tightly against the engine surface, and the overall installation stability is enhanced by the synergistic effect of the support platform 3 and the reinforcing frame 2.

[0035] After installation, check whether the sealing components are in place: the fixing post 51 is inserted into the fixing groove 42 of the boss 4, the rubber strip 8 in the fixing groove 42 is tightly fitted with the fixing post 51, the plug 52 passes through the connecting port 41, and the sealing sleeve 6 is in close contact with the inner wall of the connecting port 41 to achieve sealing of the connecting port 41.

[0036] When it is necessary to observe the internal condition of the engine, the operator holds the elliptical fixed handle 5 and applies outward pulling force to disengage the fixed post 51 from the fixed groove 42, while removing the plug 52 and the sealing sleeve 6 from the communication port 41.

[0037] The operating status of key components inside the engine can be observed through the connecting port 41 inside the boss 4. The connecting port 41 corresponds precisely to the observation hole to ensure a clear field of view.

[0038] After observation, insert the plug 52 into the connecting port 41 to ensure that the sealing sleeve 6 fits against the inner wall of the connecting port 41; at the same time, insert the fixing post 51 into the fixing groove 42, and the rubber strip 8 fits tightly against the fixing post 51 under the elastic action to achieve double fixation.

[0039] Although embodiments of the present invention have been shown and described in detail above, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
