[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 A variable intake manifold sealing mounting structure includes a mounting block 1, on which a plurality of tubes 2 are provided. The tubes 2 are located in the middle of the mounting block 1 and pass through the mounting block 1. The mounting block 1 is provided with a mounting mechanism for improving sealing. The mounting mechanism includes a sliding groove 3, which is opened inside the mounting block 1 and surrounds the plurality of tubes 2 in an annular shape. A first extrusion block 4 is slidably connected to the sliding groove 3. A plurality of telescopic rods 5 are fixed to the front end of the first extrusion block 4. A second extrusion block 6 is fixed to the front end of the plurality of telescopic rods 5. The second extrusion block 6 passes forward through the The mounting block 1 is slidably connected to it, and a spring 7 is sleeved on the telescopic rod 5. One end of the spring 7 is fixed to the first extrusion block 4, and the other end of the spring 7 is fixed to the second extrusion block 6. The rear end of the mounting block 1 is rotatably connected to a plurality of threaded rods 8. A knob 9 is fixed to the outer end of the threaded rod 8, and the other end of the threaded rod 8 passes through the mounting block 1 and is threadedly connected to the first extrusion block 4. An outer sealing rubber ring 10 is fixed to the front end of the second extrusion block 6, and an inner sealing rubber ring 11 is provided at the front end of the mounting block 1 at the position of the tube body 2. A plurality of mounting fixing holes 12 are provided at the top and bottom ends of the mounting block 1.

[0023] When this mounting structure is in use, when installing the variable intake manifold, first, the mounting block 1 is tightly fixed to the engine by passing the bolts through the mounting fixing holes 12. At the same time, the inner sealing rubber ring 11 is in close contact with the connecting port on the engine to prevent air leakage. The outer sealing rubber ring 10 is in contact with the outer wall of the engine connecting port. Turning the knob 9 drives the threaded rod 8 to rotate. The first extrusion block 4 on the threaded threaded rod 8 moves along the sliding groove 3 toward the engine. At the same time, the telescopic rod 5 contracts and the spring 7 is compressed. Under the action of the spring 7, the second extrusion block 6 drives the outer sealing rubber ring 10 to closely contact the outer wall of the engine to improve the sealing. When the bolts fixing the mounting block 1 and the engine are loosened, a gap is generated between the mounting block 1 and the engine. At this time, the spring 7 is still in an internally compressed state, giving thrust to the second extrusion block 6, so that the outer sealing rubber ring 10 always contacts the outer wall of the engine to ensure sealing.

[0024] In actual use, it is found that the tube body 2 is easily deformed by external forces, affecting performance. In order to avoid the above problem, in this embodiment, a positioning block 13 is fixed on the multiple tube bodies 2, and the positioning block 13 is located behind the mounting block 1.

[0025] In actual use, it is found that while protecting the tube body 2 from deformation due to external forces, it will affect the rotation of the knob 9. In order to avoid the above problem, in this embodiment, grooves 14 are provided at the top and bottom ends of the positioning block 13 corresponding to the knob 9 position.

[0026] In actual use, it is found that the inner sealing rubber ring 11 is easy to fall off and be lost. In order to solve the above problem, in this embodiment, a connecting strip 15 is fixed between two adjacent inner sealing rubber rings 11, and the connecting strip 15 can be embedded in the front end of the mounting block 1.

[0027] During actual use, it was found that air leakage is prone to occur at the contact point between the first extrusion block 4 and the mounting block 1. In order to avoid the above problem, in this embodiment, a leak-proof rubber ring 16 is fixed to the front end of the mounting block 1, and the outer ring side wall of the leak-proof rubber ring 16 contacts the inner ring side wall of the first extrusion block 4.

[0028] It is found in actual use that slipping is likely to occur when supporting the mounting block 1. To avoid the above problem, in this embodiment, anti-slip grooves are provided on the outer ring side wall of the mounting block 1.
