Description

Technical Field

[0001] This utility model belongs to the field of internal combustion engine technology, and in particular relates to a visualized valve cover. Background Technology

[0002] The valve cover is a crucial component of an internal combustion engine. Located at the top of the engine, it sits atop the cylinder head, ensuring that the pressure of the air-fuel mixture within the combustion chamber does not leak. It also prevents external impurities such as dust and moisture from entering the valve area. Furthermore, it protects delicate components such as valves, valve springs, valve stems, and valve guides from external damage.

[0003] Existing valve cover designs are typically made of opaque materials such as cast iron or aluminum alloy, making it impossible to directly observe the internal workings of the engine. However, if a malfunction occurs inside the valve chamber during engine operation, maintenance personnel must remove the valve cover for inspection and maintenance; this method is time-consuming, labor-intensive, and can easily damage components. Furthermore, because the valve cover is not transparent, maintenance personnel cannot directly observe the internal condition of the valve chamber while the engine is running. Utility Model Content

[0004] This invention addresses the problem that when a malfunction occurs inside the valve chamber during engine operation, maintenance personnel must remove the valve cover for inspection and maintenance. It also addresses the issue that traditional valve cover designs are not transparent, preventing maintenance personnel from directly observing the internal condition of the valve chamber while the engine is running. This invention provides a transparent valve cover that allows for direct observation of the valve chamber's interior through a clear panel. Furthermore, the transparent panel can be quickly removed, facilitating inspection and maintenance of the valve chamber through this window.

[0005] The technical solution adopted by this utility model for a visualized valve cover is as follows:

[0006] A visual valve cover includes a valve cover body with a window and a transparent cover plate detachably connected to the valve cover body. The valve cover body has stepped and U-shaped connecting rings around the window. Sliding grooves are formed on opposite side walls of the connecting rings. A slider adapted to the sliding groove is provided at the bottom of the transparent cover plate. An insertion cavity communicating with the sliding groove is provided below the connecting ring.

[0007] A further improvement of this utility model is that: the valve cover body has multiple connection holes around its perimeter for connecting with the cylinder head.

[0008] A further improvement of this utility model is that the transparent cover plate is stepped and adapted to the connecting ring.

[0009] A further improvement of this utility model is that both the groove and the slider are arranged in an L-shape, and the slider is located at the bottom edge of the transparent cover plate.

[0010] A further improvement of this utility model is that the number of insertion cavities is the same as the number of sliders, and the positions of the insertion cavities correspond one-to-one with the positions of the sliders.

[0011] A further improvement of this utility model is that each of the insertion cavities is located directly below the corresponding slider after the transparent cover plate is installed.

[0012] A further improvement of this utility model is that: the side wall of the groove provided in the connecting ring is provided with a fixed through hole through the connecting ring at the position corresponding to the insertion cavity, and a fixed rod adapted to the fixed through hole is detachably connected to the fixed through hole; wherein, when the fixed rod is located in the fixed through hole, the fixed rod is located above the horizontal section of the L-shaped slider.

[0013] A further improvement of this utility model is that: the outer wall of the fixing rod is provided with an external thread, and the inner wall of the fixing through hole is provided with an internal thread that matches the external thread of the fixing rod.

[0014] The technological advancements achieved by this utility model due to the adoption of the above technical solution are as follows:

[0015] In this invention, a transparent cover plate is provided on the valve cover body, allowing for direct observation of the interior of the valve chamber. Simultaneously, by sliding the slider out of the groove, the transparent cover plate can be quickly removed from the valve cover body, facilitating inspection and maintenance of the valve chamber through the window.

[0016] In this invention, when the slider moves into position in the groove, the transparent cover is pressed down, and the slider can be inserted into the corresponding insertion cavity. At this time, the transparent cover and the connecting ring are connected together. At the same time, the fixed rod in this invention can fix the slider in the insertion cavity, preventing the transparent cover from being pushed open upward by the internal pressure of the engine when the engine is running.

[0017] This invention replaces part of the valve cover with a transparent cover plate, thereby reducing the weight of the valve cover. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. In the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concept of this utility model.

[0027] First refer to Figure 1 and Figure 2 As can be seen, the present invention includes a valve cover body 1, which has multiple connecting holes 12 around its perimeter for connecting to the cylinder head, and a window 11 at the top of the valve cover body 1. Connecting rings 3 arranged in a U-shape are provided around the top of the valve cover body 1 at the window 11. A transparent cover plate 2 that cooperates with the connecting ring 3 is detachably connected to the connecting ring 3.

[0028] In this embodiment, the transparent cover plate 2 is made of transparent acrylic material, which can withstand temperatures up to 120°C. The transparent cover plate 2 is polished by high-temperature polishing to improve its smoothness and prevent lubricating oil splashed in the valve chamber from adhering to it and affecting the observation effect.

[0029] In this embodiment, the connecting ring 3 is arranged in a stepped shape, and the transparent cover plate 2 is also arranged in a stepped shape to cooperate with the connecting ring 3.

[0030] To facilitate the installation and removal of the transparent cover 2, such as Figures 1-5As shown, a plurality of L-shaped sliders 21 are fixedly connected to the bottom edge of the transparent cover plate 2. The number of sliders 21 is controlled between 4 and 8. In this embodiment, the number of sliders 21 is 4. At the same time, L-shaped grooves 31 that are adapted to the sliders 21 are opened on the opposite side walls (i.e., the front and rear side walls or the left and right side walls) of the connecting ring 3.

[0031] One end of each groove 31 extends to the outer wall of the connecting ring 3, and the other end of the groove 31 is located inside the side wall of the connecting ring 3.

[0032] When installing the transparent cover plate 2, the slider 21 is inserted into the groove 31 at one end of the outer wall of the connecting ring 3, extending through the groove 31. Then, the transparent cover plate 2 is pushed, causing it to move along the groove 31 until the slider 21 on the transparent cover plate 2 moves to the other end of the groove 31. At this point, the transparent cover plate 2 and the connecting ring 3 are exactly on the same vertical line. At this time, an insertion cavity 32 is provided in the connecting ring 3 below the groove 31, corresponding to the position of each slider 21. Each insertion cavity 32 is connected to the groove 31.

[0033] When the slider 21 of the transparent cover plate 2 is inserted into the groove 31, there is still a certain distance between the transparent cover plate 2 and the connecting ring 3. When the transparent cover plate 2 and the connecting ring 3 are on the same vertical line, the transparent cover plate 2 is pushed downward, and the slider 21 enters the insertion cavity 32. At this time, the stepped part of the transparent cover plate 2 and the stepped part of the connecting ring 3 are connected together. In order to further enhance the sealing performance, a sealing ring (such as a rubber sealing ring) is provided between the stepped part of the transparent cover plate 2 and the stepped part of the connecting ring 3.

[0034] To prevent the transparent cover 2 from being pushed upwards during engine operation, a fixing through hole 33 is provided on the side wall of the groove 31 of the connecting ring 3, corresponding to the position of the insertion cavity 32. The fixing through hole 33 is located above the horizontal section of the L-shaped slider 21, and the bottom edge of the fixing through hole 33 is on the same horizontal plane as the top of the horizontal section of the L-shaped slider 21. In this utility model, a fixing rod 34 that is adapted to the fixing through hole 33 is detachably connected to the fixing through hole 33.

[0035] In this embodiment, the outer wall of the fixing rod 34 is provided with an external thread, which can be provided at any position outside the fixing rod 34. At the same time, the inner wall of the fixing through hole 33 is provided with an internal thread that matches the external thread of the fixing rod 34.

[0036] After the slider 21 enters the insertion cavity 32 downwards, the fixing rod 34 can be inserted into the fixing through hole 33. At this time, the bottom edge of the fixing rod 34 is in contact with the top of the horizontal section of the L-shaped slider 21. The pressure inside the engine pushes the transparent cover 2 upwards. At this time, the fixing rod 34 can prevent the slider 21 from moving upwards, thereby preventing the transparent cover 2 from being pushed open.

[0037] When it is necessary to open the transparent cover 2, the fixing rod 34 can be removed from the fixing through hole 33, and then the transparent cover 2 can be pulled upward until the slider 21 enters the slide groove 31. Then, the transparent cover 2 can be pushed horizontally to remove the slider 21 from the slide groove 31. At this time, the transparent cover 2 can be removed from the valve cover body 1.

[0038] In the above embodiments, this utility model provides a visualized valve cover. By providing a transparent cover plate on the valve cover body, the internal condition of the valve chamber can be directly observed through the transparent cover plate. Simultaneously, by sliding the slider out of the groove, the transparent cover plate can be quickly removed from the valve cover body, facilitating inspection and maintenance of the valve chamber through the window. When the slider moves into position within the groove, pressing down on the transparent cover plate allows the slider to insert into the corresponding insertion cavity, at which point the transparent cover plate and the connecting ring are connected together. Furthermore, the fixed rod in this utility model can fix the slider within the insertion cavity, preventing the transparent cover plate from being pushed open upwards by internal engine pressure during engine operation. Additionally, by replacing part of the valve cover with a transparent cover plate, the weight of the valve cover is reduced.

[0039] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention. The technical content for which protection is sought in the present invention has been fully described in the claims.
