Abstract
Description
Technical Field
[0001] This utility model relates to an intake pipe for turbochargers, specifically a connecting structure for a turbocharger intake pipe, belonging to the field of turbocharger technology. Background Technology
[0002] A turbocharger is a supercharging device used in internal combustion engines. The turbocharger intake manifold is an important component of a turbocharged engine. It provides the turbocharger with the necessary air to ensure that the engine receives sufficient air volume under various operating conditions to support an efficient combustion process. The turbocharger intake manifold needs to be connected to an external intake manifold, which requires the use of a connection device.
[0003] However, in traditional turbocharger intake pipe connections, simple rubber sealing tubes are often used. To fit the rubber sealing tube onto the outside of the intake pipe, its radius needs to be slightly larger than the intake pipe. Since it cannot automatically adjust its radius, gaps can easily form between it and the intake pipe after installation, and the connection is prone to loosening. This can lead to unstable intake volume, preventing the turbocharger from operating at its optimal state, and consequently affecting the engine's power output and fuel economy.
[0004] To address these issues, we provide a connection structure for the intake manifold of a turbocharger. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides a connecting structure for a turbocharger intake manifold, specifically as follows:
[0006] A connecting structure for a turbocharger intake pipe includes an external intake pipe, an inner sleeve connected to the side end of the external intake pipe, a sealing groove formed on the inner wall of the inner sleeve, multiple sealing rings arranged in the sealing groove, a beveled plate formed on the outer end of the inner sleeve, multiple evenly distributed compression slots formed in the inner sleeve and the beveled plate, an external connecting pipe provided on the outer end of the inner sleeve, a beveled ring connected to the inner wall of the external connecting pipe, and a collar connected to the side end of the external connecting pipe.
[0007] Preferably, the inner sleeve is made of elastic stainless steel, the intake pipe of the turbocharger is inserted into the inner sleeve, and its outer end is in contact with the inner wall of the multi-layer sealing ring, the inner wall of the multi-layer sealing ring is flush with the inner wall of the outer intake pipe.
[0008] Preferably, the inclined panel has a trapezoidal cross-section, with the end furthest from the external air intake pipe being the high end. The outer surface of the inclined panel is smooth, and the side end of the compression slot penetrates the inner sleeve and the inclined panel.
[0009] Preferably, the external connecting pipe is made of a corrosion-resistant and high-strength alloy, and the side end of the external connecting pipe is slidably connected to the outer end of the external air intake pipe. The cross-section of the inclined ring is trapezoidal, with the end furthest from the external air intake pipe being the lower end. The inner wall of the inclined ring is smooth, and the inner wall of the inclined ring is slidably connected to the outer surface of the inclined plate.
[0010] Preferably, the multi-layer sealing ring includes an inner layer, an outer layer, and a middle layer, wherein the inner layer is a high-temperature resistant silicone sealing layer, the outer layer is an elastic rubber sealing layer, and the middle layer is a metal corrugated sealing layer.
[0011] Preferably, the outer end of the external connecting pipe is provided with two clamping plates. The clamping plate includes a first clamping plate, which is located at the outer end of the external connecting pipe. The inner wall of the first clamping plate is provided with anti-slip grooves corresponding to the outer end of the external connecting pipe.
[0012] Preferably, a second clamping plate is connected to the side end of the first clamping plate. The second clamping plate is located at the outer end of the turbocharger intake pipe and has anti-slip grooves on its inner wall. Both the outer ends of the first clamping plate and the second clamping plate are connected to connectors, and connecting bolts are provided in the connectors.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. The turbocharger intake pipe connection structure consists of an inner sleeve and an outer connecting pipe. The turbocharger intake pipe is inserted into the multi-layer sealing ring of the inner sleeve. Then, the outer connecting pipe moves towards the turbocharger intake pipe. At this time, the inclined ring and the inclined plate act to apply inward contraction pressure to the inner sleeve. Due to the existence of the compression groove, the inner sleeve can be compressed, thereby ensuring that the multi-layer sealing ring and the turbocharger intake pipe fit tightly together, thus preventing air leakage. When the outer connecting pipe moves, by reasonably selecting the position of the outer connecting pipe at the outer end of the inner sleeve, it is possible to avoid loose connection between the multi-layer sealing ring and the turbocharger intake pipe, and also to prevent the multi-layer sealing ring from being damaged due to excessive pressure.
[0015] 2. The turbocharger intake pipe connection structure is equipped with clamping plates. After the external connecting pipe is installed, two clamping plates are placed at the outer ends of the external connecting pipe and the turbocharger intake pipe, with the first clamping plate located at the outer end of the external connecting pipe and the second clamping plate located at the outer end of the turbocharger intake pipe. Then, the connecting bolts are used to connect the two clamping plates. In this way, the two clamping plates can be used to clamp and fix the external connecting pipe and the turbocharger intake pipe, thereby fixing the position of the external connecting pipe and preventing the external connecting pipe from moving again, which would cause gaps between the multi-layer sealing ring and the turbocharger intake pipe. This ensures the sealing of the connection between the turbocharger intake pipe and the external intake pipe. Attached Figure Description

Detailed Implementation
[0024] The present invention will now be further described with reference to the accompanying drawings.
[0025] Please see Figure 1 — Figure 7 The system includes an external intake pipe 1, with an inner sleeve 2 connected to the side end of the external intake pipe 1. The inner sleeve 2 is made of elastic stainless steel and has a sealing groove 3 inside. The sealing groove 3 contains multiple sealing rings 4. The intake pipe of the turbocharger is inserted into the inner sleeve 2, with its outer end fitting against the inner wall of the multiple sealing rings 4. The inner wall of the multiple sealing rings 4 is flush with the inner wall of the external intake pipe 1, so that the incoming gas will not cause wear to the connection seam between the multiple sealing rings 4 and the external intake pipe 1. The multiple sealing rings 4 include an inner layer 401, an outer layer 402, and a middle layer 403. The inner layer 401 is a high-temperature resistant silicone sealing layer to prevent the high temperature of the turbocharger from damaging the entire multiple sealing rings 4. The outer layer 402 is an elastic rubber sealing layer, which can better connect with the inner sleeve 2. The middle layer 403 is a metal corrugated sealing layer. This multi-layer sealing structure can effectively prevent gas leakage and adapt to different working environments.
[0026] The outer end of the inner sleeve 2 is set as a beveled plate 5. The cross-section of the beveled plate 5 is trapezoidal, with the end furthest from the external air intake pipe 1 being the high end. Multiple evenly distributed compression slots 6 are opened inside the inner sleeve 2 and the beveled plate 5. The side ends of the compression slots 6 penetrate through the inner sleeve 2 and the beveled plate 5, leaving deformation space for the inner sleeve 2, so that the inner sleeve 2 can be compressed and deformed inward. An external connecting pipe 7 is provided at the outer end of the inner sleeve 2. The inner wall of the external connecting pipe 7 is connected to a beveled ring 8. The external connecting pipe 7 is made of a corrosion-resistant and high-strength alloy to ensure that its structure is identical and can also support the inner sleeve 2. For protection, the side end of the external connecting pipe 7 is slidably connected to the outer end of the external air intake pipe 1. The cross-section of the inclined ring 8 is trapezoidal, with the end furthest from the external air intake pipe 1 being the lower end. The inner wall of the inclined ring 8 is smooth, and the outer surface of the inclined plate 5 is smooth. The inner wall of the inclined ring 8 is slidably connected to the outer surface of the inclined plate 5. When the inclined ring 8 and the inclined plate 5 work together, they can provide the inner sleeve 2 with the pressure of internal contraction. The side end of the external connecting pipe 7 is connected to a collar 9. The collar 9 is used to facilitate the movement of the external connecting pipe 7 by using tools, such as connecting a push cylinder to the collar 9, thereby facilitating the movement of the external connecting pipe 7.
[0027] Two clamping plates 10 are provided at the outer end of the external connecting pipe 7. The clamping plates 10 are used to clamp and fix the external connecting pipe 7 to the outer end of the turbocharger intake pipe. The clamping plate 10 includes a first clamping plate 1001, which is located at the outer end of the external connecting pipe 7. The inner wall of the first clamping plate 1001 is provided with anti-slip grooves corresponding to the outer end of the external connecting pipe 7, so as to increase the friction between the first clamping plate 1001 and the external connecting pipe 7, thereby improving the clamping and fixing effect of the first clamping plate 1001. A second clamping plate 1002 is connected to the side end of the first clamping plate 1001. At the outer end of the turbocharger intake pipe, an anti-slip groove is provided on its inner wall to increase the friction between the second clamping plate 1002 and the turbocharger intake pipe, thereby improving the clamping and fixing effect of the second clamping plate 1002. The outer ends of the first clamping plate 1001 and the second clamping plate 1002 are connected to the connectors 1003. The connectors 1003 are provided with connecting bolts. The two clamping plates 10 are connected to the connectors 1003 by the connecting bolts, so that the two clamping plates 10 can clamp and fix the external connecting pipe 7 and the turbocharger intake pipe, thereby fixing the position of the external connecting pipe 7.
