Description

Technical Field

[0001] This utility model belongs to the field of turbocharger technology, and specifically relates to a sealing structure for a turbocharger. Background Technology

[0002] With the development of the automotive industry, the performance requirements for automobiles are becoming increasingly stringent. As one of the important components of an engine, the turbocharger plays a significant role in improving performance, energy conservation, and emission reduction.

[0003] However, after prolonged use, oil leakage at the turbocharger's oil pipe connection point becomes a prominent issue. The rubber gradually ages, causing gaps in the seal between the pipes, leading to internal oil leakage and affecting the turbocharger's operation. Existing turbocharger interfaces and oil pipe connections rely solely on simple built-in sealing rubber rings, which are insufficient for stable sealing and leak prevention. Therefore, a new sealing structure for turbochargers is needed to address the problems in existing technologies. Utility Model Content

[0004] The purpose of this invention is to provide a sealing structure for a turbocharger to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing structure for a turbocharger, including an oil inlet pipe, an oil outlet pipe provided on one side of the oil inlet pipe, and a tight compression sealing mechanism provided between the oil inlet pipe and the oil outlet pipe. The tight compression sealing mechanism includes a first connecting end seat, a second connecting end seat, a mating groove, a compression ring, and mating convex teeth. The first connecting end seat is fixed to one end of the oil inlet pipe, the second connecting end seat is fixed to one end of the oil outlet pipe, the mating groove is formed at the outer edge of the end face of the first connecting end seat, the compression ring is fixed to the end face of the second connecting end seat, and the mating convex teeth are circumferentially fixed to the side surface of the compression ring.

[0006] It should be noted in the solution that a sealing gasket is provided between the first connecting end seat and the extrusion ring, and the mating protrusion is engaged with the mating groove of the first connecting end seat and the sealing gasket after combination.

[0007] It is worth noting that a receiving groove is provided on one end face of the first connecting end seat, and the extrusion ring engages and matches with the receiving groove of the first connecting end seat.

[0008] Furthermore, it should be noted that a positioning ring is finally fixed on one end face of the first connecting end seat, and the sealing gasket is sleeved on the positioning ring.

[0009] In a preferred embodiment, a positioning groove is provided on one end face of the second connecting end seat, and a sealing sleeve is fixed on the inner wall of the positioning groove of the second connecting end seat. The positioning ring engages and matches with the positioning groove and the sealing sleeve after being combined.

[0010] In a preferred embodiment, one end of the sealing sleeve extends into the inner ring of the compression ring, and both the oil inlet pipe and the second connecting end seat are provided with oil supply channels.

[0011] Compared with the prior art, the sealing structure of the turbocharger provided by this utility model has at least the following beneficial effects:

[0012] By using a tight compression sealing mechanism, the mating teeth compress the sealing gasket into the mating tooth groove of the first connecting end seat, which ensures the tightness of the mating closure between the second connecting end seat and the first connecting end seat and improves the sealing effect.

[0013] By using a positioning ring and a sealing sleeve, the positioning ring and the sealing sleeve work together to form a sealing and leak-proof layer inside the sealing gasket during use, thereby improving the sealing performance of the turbocharger's interface and oil pipe connection.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Please see Figure 1-4 This utility model provides a sealing structure for a turbocharger, including an oil inlet pipe 1, an oil outlet pipe 2 on one side of the oil inlet pipe 1, and a tight compression sealing mechanism between the oil inlet pipe 1 and the oil outlet pipe 2. The tight compression sealing mechanism includes a first connecting end seat 3, a second connecting end seat 6, a mating groove 5, a compression ring 7, and a mating protrusion 8. The first connecting end seat 3 is fixed to one end of the oil inlet pipe 1, the second connecting end seat 6 is fixed to one end of the oil outlet pipe 2, the mating groove 5 is opened at the outer edge of the end face of the first connecting end seat 3, the compression ring 7 is fixed to the end face of the second connecting end seat 6, and the mating protrusion 8 is circumferentially fixed to the side surface of the compression ring 7.

[0021] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that a sealing gasket 12 is provided between the first connecting end seat 3 and the compression ring 7, and the mating protrusion 8 is engaged with the mating groove 5 of the first connecting end seat 3 and the sealing gasket 12 after combination.

[0022] Further as Figure 3 As shown, it is worth noting that a receiving groove 4 is provided on one end face of the first connecting end seat 3, and the compression ring 7 engages and matches with the receiving groove 4 of the first connecting end seat 3.

[0023] The solution has the following working process: Before use, the sealing gasket 12 is fitted onto the positioning ring 9 at one end of the first connecting end seat 3. When the first connecting end seat 3 and the second connecting end seat 6 are mated and locked, the compression ring 7 compresses the sealing gasket 12, and at the same time, the mating protrusion 8 compresses the sealing gasket 12 into the mating groove 5 of the first connecting end seat 3. This can ensure the tightness of the mating closure between the second connecting end seat 6 and the first connecting end seat 3 and improve the sealing effect.

[0024] As can be seen from the above working process, the mating teeth 8 squeeze the sealing gasket 12 into the mating tooth groove 5 of the first connecting end seat 3, which can ensure the tightness of the mating and closure between the second connecting end seat 6 and the first connecting end seat 3 and improve the sealing effect.

[0025] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that a positioning ring 9 is finally fixed on one end face of the first connecting end seat 3, and a sealing gasket 12 is fitted on the positioning ring 9.

[0026] Further as Figure 4As shown, it is worth noting that a positioning groove 10 is provided on one end face of the second connecting end seat 6. A sealing sleeve 11 is fixed on the inner wall of the positioning groove 10 of the second connecting end seat 6. The positioning ring 9 is engaged and matched with the positioning groove 10 and the sealing sleeve 11. During use, the positioning ring 9 is embedded in the positioning groove 10 of the second connecting end seat 6, and at the same time, the positioning ring 9 is engaged with the sealing sleeve 11. In this way, the positioning ring 9 and the sealing sleeve 11 can form a sealing and leak-proof layer in the inner area of ​​the sealing gasket 12, thereby improving the sealing performance of the turbocharger interface and the oil pipe connection.

[0027] Further as Figure 1 As shown, it is worth noting that one end of the sealing sleeve 11 extends into the inner ring of the extrusion ring 7, and both the oil inlet pipe 1 and the second connecting end seat 6 are provided with oil supply channels.

[0028] In summary: the mating teeth 8 press the sealing gasket 12 into the mating tooth groove 5 of the first connecting end seat 3, which can ensure the tightness of the mating closure between the second connecting end seat 6 and the first connecting end seat 3 and improve the sealing effect; during use, the positioning ring 9 and the sealing sleeve 11 cooperate to form a sealing and leak-proof layer in the inner area of ​​the sealing gasket 12, thereby improving the sealing performance of the turbocharger interface and the oil pipe connection.
