[0023] The following is a further detailed description of the present application in conjunction with the attached Figures 1-5 This application will be further described in detail below.

[0024] The embodiments of this application disclose an upper and lower split intake manifold. Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , an upper and lower split intake manifold, including an intake manifold body 1. The intake manifold body 1 includes a top shell 101. A clamping plate 102 is installed at the bottom of the top shell 101. A top plate 103 is installed at the bottom of the clamping plate 102. A connecting pipe 104 communicates with the bottom of the top plate 103. The number of the connecting pipes 104 is multiple.

An outer pipe 107 is installed on the right side of the inner cavity of the outlet pipe 105. A sealing mechanism 2 is arranged on the right side of the surface of the outlet pipe 105;

[0025] The sealing mechanism 2 includes a fixed ring 201. The inner cavity of the fixed ring 201 is fixedly connected to the surface of the outlet pipe 105. A sealing ring 202 is fixedly connected to the right side of the inner cavity of the fixed ring 201. A sealing plate 203 is movably connected to the surface of the sealing ring 202. The inner cavity of the sealing plate 203 is fixedly connected to the surface of the outer pipe 107.

[0026] Refer to Figure 3, the surface of the sealing ring 202 is arranged in a circular ring structure, the surface of the sealing plate 203 is arranged in a conical structure, and the outer pipe 107 is arranged in an arc structure. Through the circular ring setting of the sealing ring 202 and the conical setting of the sealing plate 203, the surface of the sealing plate 203 can be closely attached to the surface of the sealing ring 202, thereby achieving the effect of sealing between the air outlet pipe 105 and the outer pipe 107 in the working state and preventing air leakage between the air outlet pipe 105 and the outer pipe 107.

[0027] Refer to Figure 3 , an internal thread 113 is provided on the right side of the inner cavity of the air outlet pipe 105, an external thread 114 is provided on the surface of the outer pipe 107, and the surface of the internal thread 113 is movably connected to the surface of the external thread 114. Through the settings of the internal thread 113 and the external thread 114, the effect of thread connection between the air outlet pipe 105 and the outer pipe 107 in the working state is achieved through the internal thread 113 and the external thread 114.

[0028] Refer to Figure 1 and Figure 2 , mounting holes 112 are provided at the four corners of the inner cavity of the bottom plate 106, and the mounting holes 112 are arranged in a circular structure. A reinforcing plate 108 is fixedly connected to the bottom of the inner side of the connecting pipe 104. Through the setting of the mounting holes 112, it is more convenient for the operator to install and fix the bottom plate 106 by installing and fixing the mounting holes 112. Through the setting of the reinforcing plate 108, the effect of strengthening between the connecting pipes 104 in the working state is achieved, and the phenomenon that the connecting pipes 104 shake and shift during the working process is avoided.

[0029] Refer to Figure 1 、 Figure 2 and Figure 5 , a connecting frame 109 is fixedly connected to the back side of the top shell 101, and slot holes 110 are provided at the four corners of the inner cavity of the connecting frame 109. The slot holes 110 are arranged in a circular structure. Through the settings of the slot holes 110 and the connecting frame 109, it is more convenient for the operator to install the connecting frame 109 by installing the slot holes 110, thereby achieving the effect of installing and fixing the connecting frame 109 in the working state and further realizing the effect of installing and fixing the top shell 101 and external parts through the connecting frame 109.

[0030] Refer to Figure 4 and Figure 5, a clamping groove 116 is formed around the bottom of the inner cavity of the clamping plate 102, a clamping block 115 is fixedly connected around the top of the top plate 103, and the surface of the clamping block 115 is movably connected to the inner cavity of the clamping groove 116. Through the arrangement of the clamping groove 116, the clamping block 115 can be smoothly inserted into the inner cavity of the clamping plate 102, thereby achieving the effect of positioning between the clamping plate 102 and the top plate 103 in the working state, and further facilitating the subsequent installation and fixation of the top shell 101, the clamping plate 102 and the top plate 103 by the operator.

[0031] Refer to Figure 2 , Figure 4 and Figure 5 , jacks 117 are formed around the inner cavities of the top shell 101, the clamping plate 102 and the top plate 103. The jacks 117 are arranged in a circular structure, and bolts 111 are movably connected to the inner cavities of the jacks 117. Through the arrangement of the jacks 117, the bolts 111 can be smoothly inserted into the inner cavities of the top shell 101, the clamping plate 102 and the top plate 103, thereby achieving the effect of installing and fixing the top shell 101, the clamping plate 102 and the top plate 103 in the working state.

[0032] Working principle: First, hold the top shell 101 by hand and place it on the top of the clamping plate 102. Then, place the clamping plate 102 on the top of the top plate 103, so that the surface of the clamping block 115 is inserted into the inner cavity of the clamping groove 116, thereby achieving the positioning effect between the clamping plate 102 and the top plate 103 in the working state. When the top shell 101, the clamping plate 102 and the top plate 103 reach the specified position, insert the bolt 111 into the jack 117 in the inner cavities of the top shell 101, the clamping plate 102 and the top plate 103 by hand, so as to achieve the effect of installing and fixing the top shell 101, the clamping plate 102 and the top plate 103 in the working state. Secondly, hold the outer tube 107 by hand and rotate it by the operator, and make the outer tube 107 insert into the inner cavities of the air outlet pipe 105 and the fixing ring 201. Then, under the action of the meshing of the internal thread 113 and the external thread 114, the air outlet pipe 105 and the outer tube 107 are threadedly connected. At the same time, the movement of the outer tube 107 drives the sealing plate 203 to move, so that the sealing plate 203 moves into the inner cavity of the fixing ring 201. And because the sealing plate 203 is conical, the surface of the sealing plate 203 gradually fits tightly with the surface of the sealing ring 202, thereby achieving the sealing effect between the air outlet pipe 105 and the outer tube 107 in the working state. Finally, hold the top shell 101 by hand and place it at the specified position, so that the back side of the connecting frame 109 and the bottom of the bottom plate 106 are tightly attached to the part to be installed. When the bottom plate 106 and the connecting frame 109 reach the specified position, fix the slot hole 110 and the mounting hole 112 by the operator to achieve the effect of installing and fixing the connecting frame 109 and the bottom plate 106 to the outside in the working state. Then, air enters through the connecting frame 109, and then the air can be evenly distributed into the interior of each connecting pipe 104, so as to ensure the smoothness and efficiency of the engine operation. Then, it is discharged through the air outlet pipe 105 and the outer tube 107, and at the same time, the sealing effect between the air outlet pipe 105 and the outer tube 107 in the working state is achieved through the sealing ring 202 and the sealing plate 203.
