Description

Technical Field

[0001] This utility model relates to the field of turbocharger intermediate housing technology, and in particular to an intermediate housing for a turbocharger. Background Technology

[0002] A turbocharger is actually an air compressor that increases the intake air volume by compressing air. It uses the inertial force of the exhaust gas from the engine to drive the turbine in the turbine housing. The turbine then drives the coaxial impeller, which compresses the air delivered from the air filter and forces it into the cylinder.

[0003] A search revealed Chinese patent CN216240834U, which discloses a turbocharger intermediate housing. This device features a quick-installation structure, which addresses the lack of such a structure in existing turbocharger intermediate housings. However, the quick-installation connector uses a spring to push a connecting rod to engage a limiting block into a limiting groove. During use, vibration can easily cause the limiting block to detach from the limiting groove, resulting in a disconnection. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a turbocharger intermediate housing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A turbocharger intermediate housing includes an intermediate housing body and a connecting body. A connecting groove is formed on one inner wall of the intermediate housing body. Circular grooves are formed at the top and bottom of the intermediate housing body. Square grooves are formed on the sides of the top and bottom of the intermediate housing body, and the square grooves are connected to the circular grooves. Circular holes are formed at the top and bottom of the connecting body. A sliding rod is provided in the circular hole. A connecting rod is fixedly connected inside the sliding rod. A square plate is fixedly connected to one end of the connecting rod, and the square plate passes through the square groove and enters the circular groove.

[0007] As a further embodiment of this utility model, a limiting ring is fixedly connected to the outer circumference of one end of the slide rod, and the diameter of the inner ring of the limiting ring is larger than the diameter of the circular hole.

[0008] As a further embodiment of this invention, the protrusion portion of the connector is inserted into the connecting groove.

[0009] As a further improvement of this utility model, a first sealing ring is fixedly connected to one side of the connecting groove.

[0010] As a further embodiment of this invention, a second sealing ring is fixedly connected to one side of the connector, and the first sealing ring is in contact with the second sealing ring.

[0011] As a further embodiment of this utility model, the square groove corresponds to the square plate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0024] Reference Figures 1-5 A turbocharger intermediate housing includes an intermediate housing body 1 and a connecting body 2. A connecting groove 4 is formed on one inner wall of the intermediate housing body 1. Circular grooves 12 are formed at the top and bottom of the intermediate housing body 1. Square grooves 11 are formed on the sides of the top and bottom of the intermediate housing body 1, and the square grooves 11 communicate with the circular grooves 12. The connecting body 2 is inserted into the connecting groove 4 of the intermediate housing body 1 through a protrusion on its side, so that the intermediate housing body 1 and the connecting body 2 are in contact. At this time, the vertical square plate 8 corresponds to the position of the square groove 11. Both the top and bottom of the 2 are provided with round holes 3. A sliding rod 10 is provided in the round hole 3. A connecting rod 7 is fixed inside the sliding rod 10 by bolts. A square plate 8 is fixed to one end of the connecting rod 7 by bolts. The square plate 8 passes through the square groove 11 and enters the round groove 12. Pushing the sliding rod 10 makes the vertical square plate 8 pass through the square groove 11 and enter the round groove 12. Then, rotating the sliding rod 10 makes the square plate 8 change from a vertical state to a horizontal state and make close contact with the inner wall of the round groove 12, thereby making a stable connection between the intermediate shell body 1 and the connecting body 2.

[0025] In this utility model, it should be noted that a limiting ring 9 is welded to the outer circumference of one end of the slide rod 10, and the diameter of the inner ring of the limiting ring 9 is larger than the diameter of the circular hole 3. The limiting ring 9 can limit the distance the slide rod 10 can move, preventing the slide rod 10 from moving excessively and affecting the use of the device. The protrusion of the connecting body 2 is inserted into the connecting groove 4. A first sealing ring 5 is bonded to one side of the connecting groove 4, and a second sealing ring 6 is bonded to one side of the connecting body 2. The first sealing ring 5 and the second sealing ring 6 are in contact. The sealing ring 6 makes the connection between the intermediate shell body 1 and the connecting body 2 tighter. The square groove 11 corresponds to the position of the square plate 8. A threaded hole is opened on one side of the limiting ring 9, and a screw is threaded into the threaded hole. An insertion port is opened on one side of the outer wall of the connecting body 2, and the screw is inserted into the insertion port. When the square plate 8 enters the circular groove 12 and rotates from the vertical state to the horizontal state, the screw is inserted from the threaded hole into the insertion port, so that the position of the moved square plate 8 is fixed, thereby making the connection between the intermediate shell body 1 and the connecting body 2 more secure.

[0026] Working principle: When it is necessary to connect the intermediate shell body 1 and the connecting body 2, the connecting body 2 is first inserted into the connecting groove 4 of the intermediate shell body 1 through the protrusion on the side, so that the intermediate shell body 1 and the connecting body 2 are in contact, and the first sealing ring 5 and the second sealing ring 6 are in contact. At this time, the vertical square plate 8 corresponds to the position of the square groove 11. Push the slide rod 10 so that the vertical square plate 8 passes through the square groove 11 and enters the circular groove 12. Then rotate the slide rod 10 so that the square plate 8 changes from a vertical state to a horizontal state and contacts the inner wall of the circular groove 12. Then insert the screw into the socket from the threaded hole so that the position of the square plate 8 is fixed, thereby achieving a stable connection between the intermediate shell body 1 and the connecting body 2.

[0027] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
