[0029] The following will be combined with the drawings Figures 1-6 The utility model is further explained.

[0030] In order to solve the problems in the background art, the present application proposes the following technical scheme: including a support rod 1, two groups of valve pieces 2 are fixedly connected outside the support rod 1, a first rotating shaft 4 is fixedly installed on one side of the support rod 1, a second rotating shaft 5 is fixedly connected on the side of the support rod 1 away from the first rotating shaft 4, the support rod 1, the two groups of valve pieces 2, the first rotating shaft 4 and the second rotating shaft 5 form a unit valve body, a connecting rod 7 is fixedly connected to one end of the first rotating shaft 4 away from the support rod 1, a connecting groove 8 is formed in one end of the second rotating shaft 5 away from the support rod 1, the connecting groove 8 is matched with the connecting rod 7, an installation groove 9 is formed in the connecting rod 7, a clamping head 10 is slidably installed in the installation groove 9, a clamping groove 12 is formed in the connecting groove 8, the clamping head 10 is matched with the clamping groove 12, a first spring 11 is fixedly installed in the installation groove 9, one end of the first spring 11 is fixedly connected with the clamping head 10.

[0031] When the adjacent unit valve bodies are connected, the connecting rod 7 on one side of the first rotating shaft 4 is inserted into the connecting groove 8 of the second rotating shaft 5 on the adjacent support rod 1, in the process of insertion, the second rotating shaft 5 contacts and extrudes the clamping head 10, because the upper end of the clamping head 10 is a smooth arc, the second rotating shaft 5 extrudes the clamping head 10 to move it to the inside of the installation groove 9, the clamping head 10 moves to compress the first spring 11, after the connecting rod 7 is inserted into the connecting groove 8, the position of the clamping head 10 corresponds to the clamping groove 12, the compressed first spring 11 pushes the clamping head 10 to move into the clamping groove 12 to restore the initial state, the clamping groove 12 limits the movement of the clamping head 10, thereby connecting the first rotating shaft 4 and the second rotating shaft 5 together, the initial state of the first spring 11 is also a compressed state, the first spring 11 keeps the clamping head 10 in the clamping groove 12, improving the stability of the connection between the first rotating shaft 4 and the second rotating shaft 5, through the above-mentioned manner, multiple unit valve bodies are connected into a whole control valve piece, when the valve piece 2 of one of the unit valve bodies is worn, a tool is inserted into the clamping groove 12 to press the clamping head 10 into the installation groove 9, at this time, the clamping groove 12 no longer limits the clamping head 10, thereby releasing the connection between the first rotating shaft 4 and the second rotating shaft 5 of the adjacent valve bodies, the worn unit valve body can be removed and replaced from the whole control valve piece, thereby avoiding the waste of the control valve piece and reducing the use cost of the control valve piece for the variable length intake manifold.

[0032] Further, a cross clamping column 14 is arranged on the first rotating shaft 4, an insertion slot 16 is formed in the connecting rod 7, the insertion slot 16 is matched with the cross clamping column 14.

[0033] When the adjacent first rotating shaft 4 and second rotating shaft 5 are connected, the cross clamping column 14 is inserted into the insertion slot 16, the cross clamping column 14 cooperates with the insertion slot 16 to improve the stability when the first rotating shaft 4 and the second rotating shaft 5 are connected, and improve the stability when the first rotating shaft 4 and the second rotating shaft 5 rotate.

[0034] Further explanation is that the first rotating shaft 4 is internally provided with a sliding slot 13, one end of the cross clamping column 14 is slidingly installed in the sliding slot 13, and the second spring 15 is fixedly installed in the sliding slot 13. One end of the second spring 15 is fixedly connected with the cross clamping column 14.

[0035] When the adjacent first rotating shaft 4 and the second rotating shaft 5 are connected, the cross clamping column 14 is inserted into the insertion slot 16, at this time the second spring 15 is in a compressed state, the compressed second spring 15 makes the cross clamping column 14 always have a tendency to move into the insertion slot 16, so that the cross clamping column 14 is always in the insertion slot 16, thereby improving the stability of the cross clamping column 14 during cooperation with the insertion slot 16.

[0036] Further explanation is that a limiting slot 17 is formed on the inner wall of the sliding slot 13, and a limiting strip 18 is slidingly installed in the limiting slot 17. The limiting strip 18 is fixedly installed on the outer surface of the cross clamping column 14.

[0037] The limiting slot 17 and the limiting strip 18 guide and limit the movement of the cross clamping column 14, improve the smooth movement of the cross clamping column 14 in the sliding slot 13, and make the cross clamping column 14 and the insertion slot 16 can be accurately aligned.

[0038] Further explanation is that the cross sections of the two groups of valve plates 2 are arc-shaped, and the two groups of valve plates 2 on the support rod 1 are symmetrically arranged.

[0039] The arc-shaped arrangement of the valve plate 2 utilizes the inertial effect of airflow, forms a certain supercharging effect during the intake process, helps to improve the intake pressure, and in turn increases the intake amount, which is beneficial to the power output of the engine at high speed.

[0040] Further explanation is that the two groups of valve plates 2 are fixedly connected with the edge covering 3 away from the support rod 1.

[0041] The material of the edge covering 3 is fuel-resistant rubber, the edge covering 3 contacts the inside of the intake manifold air duct, and the edge covering 3 matches the inner wall of the air duct, thereby improving the sealing performance of the air duct and the durability of the valve plate 2.

[0042] Further explanation is that two groups of flow guide grooves 6 are formed on the support rod 1, and the two groups of flow guide grooves 6 are symmetrically distributed.

[0043] The arrangement of the flow guide groove 6 reduces the intake resistance of the valve plate 2, and at the same time guides the airflow entering the intake pipe to flow along the predetermined path, thereby reducing the turbulence and vortex phenomenon of the airflow in the manifold.

[0044] Specifically, referring to the following operation: when connecting between adjacent unit valve bodies, the connecting rod 7 on the first rotating shaft 4 side is inserted into the connecting groove 8 of the second rotating shaft 5 on the adjacent support rod 1, the compressed first spring 11 makes the clamping head 10 enter the clamping groove 12, the clamping groove 12 limits the movement of the clamping head 10, the first rotating shaft 4 and the second rotating shaft 5 are connected together, and the cross clamping column 14 is inserted into the insertion slot 16, the compressed second spring 15 makes the cross clamping column 14 always in the insertion slot 16, and the above-mentioned way connects multiple unit valve bodies into a whole control valve piece, when one of the unit valve bodies is worn, the clamping head 10 is pressed into the mounting groove 9 by inserting a tool into the clamping groove 12, at this time the clamping groove 12 no longer limits the clamping head 10, and the connection between the first rotating shaft 4 and the second rotating shaft 5 of the adjacent valve bodies can be released, and the worn unit valve body can be removed from the whole control valve piece for replacement.
