It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0057] The split intake manifold provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0058] Embodiment 1:

[0059] like Figures 1 to 10As shown, the embodiment of the present application provides a split intake manifold, including a mixing chamber 3 provided with an intake pipe 1 and a plurality of outlet pipes 2, the mixing chamber 3 including a shell 31, one side of which is connected to the intake pipe 1 and the other side is open; a shell cover 32, which is detachably mounted on the open side of the shell 31 through a plurality of quick-release devices 4; the quick-release device 4 includes an insert shell 41, which is fixed on the outer wall of the shell 31 and is open toward the shell cover 32; an insert plate 42, which is fixed on the shell cover 32 and can be inserted into the insert shell 41, and one side of the insert plate is provided with a slot 43; a locking block mechanism 44, which is movably mounted on the insert shell 41, and the insert plate 42 is fixed in the insert shell 41 when engaged with the slot 43.

[0060] Furthermore, the locking block mechanism 44 includes a through slot 441, which is arranged at the top of the plug shell 41, and one end of which is provided with a locking slot 442 located above the slot 43; a slide plate 443, which can be slidably installed on the top of the inner cavity of the shell 31, and one side is fixed with a locking column 444 that can slide in the through slot 441, the locking slot 442 and the slot 43; a tension spring 445, one end of which is fixed to the inner end wall of the inner cavity of the plug shell 41 away from the through slot 441, and the other end is fixed to the slide plate 443.

[0061] In this embodiment of the present application, due to the adoption of the above-mentioned structure, during installation, ensure that each lock column 444 is located at the end of the corresponding through slot 441 away from the lock slot 442, and then insert each plug plate 42 into the corresponding plug shell 41, so that the card slot 43 on each plug plate 42 corresponds to the lock slot 442 on each plug shell 41, and apply a thrust to the surface of the lock column 444 facing away from the card slot 43 and the lock slot 442, and move each lock column 444 in the direction of the lock slot 442 and the card slot 43. In this process, the tension spring 445 stretches until the lock column 444 moves to the corresponding lock slot 442 and the card slot 43. The locking pin 444 is in a state of being unable to return to the end of the corresponding through slot 441 away from the locking slot 442, and the tension spring 445 is arranged obliquely, so as to pull the slide plate 443 and the locking pin 444 to move along the extending direction of the slot 43 and the locking slot 442 until the end of the slide plate 443 away from the through slot 441 is pressed against the side wall of the lock shell cavity away from the through slot 441, at which time the locking pin 444 enters the slot 43 and the locking slot 442, and the plug plate 42 cannot slide out of the lock shell, thus completing the fixing between the shell cover 32 and the shell body 31;

[0062] When removing the shell cover 32, a thrust is applied to the lock post 444 toward the side wall of the card slot 43, and the lock post 444 is pushed away from the card slot 43 and the lock slot 442. During this process, the tension spring 445 is extended, and the side wall of the slide plate 443 away from the through slot 441 is out of contact with the inner wall of the plug shell 41 until the lock post 444 completely enters the through slot 441. The tension spring 445 retracts under its own elastic force. At this time, the lock post 444 is pushed toward the side wall of the card slot 43. The locking column 444 can only slide toward the end of the through slot 441 away from the card slot 43 until the inner end side wall of the slide plate 443 facing away from the shell cover 32 also abuts against the inner end wall of the lock shell cavity. The locking column 444 is misaligned with the lock slot 442 and the through slot 441. Under the action of the tension spring 445, it cannot enter the lock slot 442 and the through slot 441. At this time, each plug plate 42 can slide out of the plug shell 41, and then the shell cover 32 can be removed from the shell 31.

[0063] The distance between the overlapping position of the locking slot 442 and the sliding slot 446 and the connection point between the tension spring 445 and the inner cavity of the plug shell 41 is greater than the distance between the inner end of the locking slot 442 or the end of the sliding slot 446 away from the locking slot 442 and the connection point between the tension spring 445 and the inner cavity of the plug shell 41.

[0064] Embodiment 2:

[0065] like Figures 2 to 10 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the locking block mechanism 44 also includes a pair of slide grooves 446, both of which are L-shaped and symmetrically arranged on the top of the plug shell 41; a pair of through grooves 447, respectively arranged at the bottom of each slide groove 446, connecting the inner cavity of the plug shell 41; a pair of bolts 448, respectively slidably installed in each slide groove 446, and the lower end is fixed to the slide plate 443 through screw holes.

[0066] Furthermore, it also includes a side slide groove 51, which is arranged on the side wall adjacent to the plug shell 41 and the card slot 43; a side slider 52, which can be slidably inserted in the side slide groove 51, and one end extends to the bottom of the through groove 441; a locking column 53, which can be slidably installed in the through groove 441, and the lower end is fixedly connected to the end of the side slider 52 extending out of the side slide groove 51; a locking member 54, which is used to cooperate with the locking column 53 to prevent the side slider 52 from sliding in the side slide groove 51 in the direction away from the locking groove 442.

[0067] Furthermore, it also includes an insertion rod 55 , two ends of which are fixedly connected to two ends of the side sliding groove 51 , and the middle part can be slidably arranged in the side sliding block 52 .

[0068] Furthermore, a return spring 56 is included, which is arranged between the end of the side sliding groove 51 adjacent to the locking groove 442 and the adjacent end of the side sliding block 52.

[0069] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the slider moves in the inner cavity of the lock shell, a pair of bolts 448 also slide in the corresponding sliding grooves 446 and the through grooves 447. When the lock column 444 is inserted into the lock groove 442 and the card slot 43, the locking column 53 is pushed to slide toward the connecting end of the through groove 441 and the lock groove 442. At this time, the side slider 52 also slides in the side sliding groove 51 in the corresponding direction, and the return spring 56 is compressed to store elastic potential energy until the end of the side slider 52 extending out of the side sliding groove 51 abuts against the side wall of the lock column 444, and then the lock member 54 automatically locks the lock column 444. The compressed return spring 56 can also enhance the locking state of the lock column 53 and the lock member 54, ensuring that the lock column 444 cannot be separated from the lock groove 442 and the card slot 43.

[0070] When it is necessary to disengage the locking column 444 from the locking slot 442 and the card slot 43, the locking piece 54 is operated to release the cooperation with the locking column 53, and the return spring 56 releases its elastic potential energy to push the side slide block 52 to slide toward the other end of the side slide slot 51 and away from the locking column 444. Then, the locking column 444 can be moved to disengage it from the locking slot 442 and the card slot 43.

[0071] Embodiment 3:

[0072] like Figures 2 to 10 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the locking member 54 includes a locking rod 541, a portion of which is rotatably mounted on the top surface of the plug shell 41 through a hinge; a locking port 542, which is arranged at one end of the locking rod 541 and can be engaged with the locking column 53 when it moves to a position corresponding to the locking groove 442.

[0073] Furthermore, the locking member 54 further includes a stop plate 543 , which is fixed on the top surface of the plug housing 41 . When the locking port 542 is engaged with the locking column 53 , it abuts against the side wall of the locking rod 541 away from the through slot 441 .

[0074] Furthermore, the locking member 54 also includes an arc groove 544, which is arranged on the top surface of the plug shell 41 and is concentric with the hinge axis; a reset slider 545, which is fixed on the bottom surface of the locking rod 541 and slides in the arc groove 544; a pressure spring, one end of which abuts against one end of the arc groove 544 away from the stop plate 543, and the other end abuts against the reset slider 545.

[0075] Furthermore, it also includes an avoidance groove 547 which is arranged on the top of the locking column 444 .

[0076] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the lock column 444 and the locking column 53 slide toward the lock groove 442, the side wall of the lock rod 541 with the lock hole 542 at one end slides and rubs against the side walls of the lock column 444 and the locking column 53, the pressure spring is compressed and shortened, and the reset slider 545 is located in the middle position of the arc groove 544 until the lock column 444 is inserted into the lock groove 442 and the card groove 43. At this time, the end surface of the side slider 52 and the lock column 444 are in contact with the side wall of the through groove 441, and the locking column 53 is also separated from the contact with the end of the lock rod 541 with the lock hole 542 At this time, the pressure spring releases its elastic potential energy, pushing the reset slider 545 to slide toward the end of the arc groove 544 away from the through groove 441, and the locking rod 541 rotates around the pin shaft, and one end with the lock hole 542 moves to the top of the through groove 441, and one side of the other end abuts against the adjacent side wall of the stop plate 543, and then the locking column 53 can be released. Under the action of the reset spring 56, the side slider 52 moves slightly toward the end of the through groove 441 away from the lock groove 442 and the card slot 43, but still maintains contact with the lock column 444, so that the locking column 53 enters the lock hole 542, completing the locking action;

[0077] When it is necessary to contact the end face of the side slider 52 with the side wall of the locking column 444, the end of the locking rod 541 without the locking hole 542 is pushed in the direction of the through groove 441, so that the locking rod 541 rotates around the pin shaft, and the locking hole 542 with the locking hole 542 end is disengaged from the locking column 53, and the reset spring 56 releases its elastic potential energy, so that the side slider 52 and the locking column 53 are away from the locking column 444.

[0078] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise one..." do not exclude the presence of other identical elements in the process, method, article or device including the element.
