Description

Technical Field

[0001] This utility model relates to the field of engine cylinder technology, and more specifically, to an engine cylinder head. Background Technology

[0002] A cylinder is a cylindrical chamber inside an engine containing a piston that is pushed by the pressure or expansion force of the working fluid. In some special types of engines, there is a similar but non-cylindrical part. When the cylinder is sealed, the cylinder head is required. When the existing cylinder head body is sealed and fixed to the cylinder body, the gaskets between the two cannot effectively abut and clamp together, resulting in a problem that the fixation is not very tight.

[0003] To address the aforementioned issues, patent document publication number CN221879558U discloses an engine cylinder head, comprising an oil return hole, cylinder head bolt holes, two side through holes, and a cylinder head body. The cylinder head body has two side through holes on its inner sides at both ends, an exhaust port sleeve on the inner side of the upper end of the cylinder head body, and cylinder head bolt holes on the outer side of the exhaust port sleeve located on the cylinder head body.

[0004] However, it still has some drawbacks in actual use. For example, if the elastic contactor or movable pressure plate in the cylinder head is damaged, the entire cylinder head body needs to be disassembled and repaired, and the entire structure may even need to be replaced. The whole maintenance process is quite complicated, which reduces the practicality of the device to a certain extent. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an engine cylinder head to solve the problem that the elastic contactor and movable pressure plate provided in the prior art cylinder head are inconvenient to disassemble and maintain.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an engine cylinder head, including a cylinder head body, wherein the engine cylinder head further includes...

[0007] A connecting seat is provided inside the side of the cylinder head body. A mounting shaft is fixedly connected to the right side of the connecting seat. One end of the mounting shaft is rotatably connected to the inner wall of the cylinder head body. A mounting shaft is fixedly installed on the left side of the connecting seat. One end of the mounting shaft is penetrating the inner wall of the cylinder head body.

[0008] A retaining ring is provided on both sides of the cylinder head body along its length, and the inner ring of the retaining ring is rotatably connected to one end of the mounting shaft relative to the connecting seat.

[0009] The abutting end post has a movable panel fixedly installed on the side of its bottom. A spring is installed inside the abutting end post, and a positioning end is fixedly connected to one end of the spring relative to the abutting end post. The top of the positioning end is sleeved with the bottom of the connecting seat.

[0010] It also includes a bonding pad, which is disposed on the surface of the positioning end. The outer periphery of the bonding pad is configured with a rough surface structure, and the surface of the bonding pad is in contact with the inner wall of the bottom of the connecting seat.

[0011] It also includes a connecting column, a mounting rod, a movable rod, and a connecting end. The connecting column is rotatably mounted on the inner wall of the side of the cylinder head body. The top end of the mounting rod is fixedly connected to the surface of the connecting column. The movable rod is movably mounted inside the mounting rod. The connecting end is located at the bottom end of the movable rod, and the outer periphery of the bottom of the connecting end is in contact with the inner wall of the top surface of the movable panel.

[0012] The connecting end is internally fixedly connected to a second spring, and an L-shaped plate is fixedly connected to one end of the second spring relative to the connecting end. The surface of the L-shaped plate is in contact with the inner wall of the connecting end, and a snap-fit ​​plate is provided on one side of the bottom of the L-shaped plate. The surface of the snap-fit ​​plate is snapped into the side of the movable panel.

[0013] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0014] In the above scheme, when it is necessary to disassemble and maintain the contact end post or movable panel along with the corresponding components, the movable panel is moved vertically upward, causing the movable rod to retract into the mounting rod, and the spring 1 set between the positioning end and the contact end post is compressed. At this time, a certain space is left between the contact end post, the movable panel and the cylinder. Then, the connecting seat is rotated around the mounting shaft 2, so that the contact end post and the movable panel can rotate synchronously and move out from the inside of the side of the cylinder head body. Then, the positioning end can be separated from the connecting seat, and the connecting end can be separated from the surface of the movable panel to complete the disassembly work. Therefore, it is not necessary to disassemble the entire cylinder head body to disassemble and maintain the contact end post, the movable panel and the corresponding components, which simplifies the maintenance process and thus improves the practicality of the device.

[0015] By moving the L-shaped plate located around the connecting end horizontally, the second spring deforms, and the snap-fit ​​plate installed on the surface of the L-shaped plate moves synchronously and separates from the side of the movable panel. This allows the connecting end to detach from the surface of the movable panel, enabling the movable panel to be disassembled. In addition, it also ensures the stability of the connecting end after it is fitted onto the top of the movable panel, further improving the practicality of the device. Attached Figure Description

The surface of the L-shaped plate 16 is in contact with the inner wall of the connecting end 14. A snap-fit ​​plate 17 is provided on one side of the bottom of the L-shaped plate 16, and the surface of the snap-fit ​​plate 17 is snapped with the side of the movable panel 7.

[0029] The working process of this utility model is as follows: When it is necessary to disassemble and maintain the contact end post 6 or the movable panel 7 together with the corresponding components, the movable panel 7 is moved vertically upward, so that the movable rod 13 retracts into the mounting rod 12, and the spring 8 set between the positioning end 9 and the contact end post 6 is compressed. At this time, a certain space is left between the contact end post 6, the movable panel 7 and the cylinder. Then, the connecting seat 2 is flipped around the mounting shaft 4, so that the contact end post 6 and the movable panel 7 can rotate synchronously and move out from the inside of the side of the cylinder head body 1. Then, the positioning end 9 can be separated from the connecting seat 2, and the connecting end 14 can be separated from the surface of the movable panel 7 to complete the disassembly work.
