[0016] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0017] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0018] like Figure 1As shown, this application discloses a sealing fixture for leak testing of engine cylinder heads, including: a bracket 4 and a sealing assembly; the sealing assembly includes a first sealing assembly 1 and a second sealing assembly 2 disposed at one end of the bracket 4, the first sealing assembly being provided with a sealing plate 22 and a connecting member, the second sealing assembly 2 also being provided with a sealing plate 22 and a connecting member, the connecting member being rotatably connected to the sealing plate 22, and an adjusting member 23 being fixedly connected to the connecting member; a driving assembly disposed at the other end of the bracket 4, used to drive the sealing assembly to releasably seal and seal the sealing surfaces of the exhaust port and intake port of the engine cylinder head; an adjusting member, used to adjust the distance between the first sealing assembly 1 and the second sealing assembly 2; wherein, the driving assembly and the first sealing assembly 1 are adjustablely connected through the adjusting member 23. In this application, by setting an adjusting member 23 that can adjust the distance between the sealing plates 22 of the first sealing assembly 1 and the second sealing assembly 2, compatibility with engines with non-parallel exhaust ports is achieved; the whole adopts a modular standardized design and each part is simple to manufacture, with low maintenance costs and convenient for later upgrades, replacements, maintenance and repair.

[0019] like Figure 1-2 As shown, in this embodiment, the connector includes a connecting rod 21. One end of the connecting rod 21 is provided with a universal ball 211. The connecting rod 21 is rotatably connected to the sealing plate 22 through the universal ball 211. The other end of the connecting rod 21 can be detachably fixedly connected to the bracket 4 or detachably fixedly connected to the adjusting component 23 in the drive assembly. The sealing plate 22 has a receiving groove that cooperates with the universal ball 211. By adopting this rotatable connection method of the universal ball 211, the sealing plate 22 can be freely adjusted to fit with the air intake or exhaust port of the cylinder head 5, and it is compatible with engines with non-parallel air intake and exhaust ports. At the same time, by setting latex blocks on the sealing plate 22, a sealing effect can be achieved. The other end of the connecting rod 21 of the second sealing plate 2 is detachably fixed to the bracket 4.

[0020] In this embodiment, the drive assembly also includes a handle 32, which is hinged to a slide rod 31. One end of the connecting rod 21 is provided with a universal ball 211 that is rotatably connected to the sealing plate 22. The other end of the connecting rod 21 is fixed to the bracket 4 by a threaded connection, or the other end of the connecting rod 21 is fixed to the adjusting member 23 in the drive assembly by a threaded connection. The adjusting member 23 is fixed to the slide rod 31 by a threaded connection. The slide rod 31 can slide inside the drive assembly. The slide rod 31 is fixed to the handle 32 by a hinge connection. The length of the adjusting member 23 between the connecting rod 21 and the slide rod 31 is adjusted by adjusting the thread engagement between the adjusting member 23 and the slide rod 31. The overall clamping force is adjusted by the change in the length of the adjusting member 23, thereby achieving different sealing forces. In this application, by setting a connecting rod 21 with a universal ball 211 to be rotatably connected to the sealing plate 22 so that the sealing plate 22 can rotate flexibly, and by setting an adjusting member 23 between the connecting rod 21 and the sealing plate 22 to adjust the distance between them, it is possible to achieve compatibility with engines with non-parallel exhaust ports. In this embodiment, the connecting rod 21 of the first sealing plate 1 is hollow inside and has threads on its inner wall. One end of the adjusting member 23 has a threaded section and is fixed inside the connecting rod 21 of the first sealing assembly 1 by a threaded connection, thereby achieving an adjustable connection between the adjusting member 23 and the connecting rod 21. At this time, the other end of the adjusting member 23 can be integrally formed with the slide rod 31; or, the slide rod 31 is hollow inside and has threads on its inner wall, and the other end of the adjusting member 23 has a threaded section and is fixed inside the slide rod 31 by a threaded connection. By adjusting the length of the adjusting member 23 between the connecting rod 21 and the slide rod 31, the distance between the sealing plates 22 between the first sealing assembly 1 and the second sealing assembly 2 can be adjusted, thereby achieving compatibility with engines whose exhaust ports are not parallel.

[0021] In another embodiment, such as Figure 3 As shown, one end of the adjusting member 23 is integrally formed with the connecting rod 21 of the first sealing plate 1, and the other end of the adjusting member is provided with a threaded section.
