Description

Technical Field

[0001] This utility model relates to the technical field of fuel injector sealing gasket pressing device, and in particular to a fuel injector sealing gasket pressing device. Background Technology

[0002] A car fuel injector is a solenoid valve that is precisely controlled by a computer. Its basic task is to inject the correct amount of fuel into the engine's intake manifold or cylinder at the correct time and in the correct form.

[0003] The existing automotive fuel injector is an important component of a car, and it has two annular mounting grooves for installing a sealing ring. Normally, mechanics have to forcefully expand the sealing ring to install it. However, during installation, the sealing ring is prone to slipping out of the hand or accidentally fitting onto the outer surface of the fuel injector. Furthermore, the frictional resistance between the sealing ring and the fuel injector after fitting is relatively high, making it difficult for mechanics to push the sealing ring forward. Therefore, the existing method of installing sealing rings on automotive fuel injectors is inconvenient. To address this, we provide a fuel injector sealing gasket clamping device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies in which the installation of fuel injector sealing rings is not convenient enough, and to provide a fuel injector sealing gasket clamping device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a fuel injector sealing gasket pressing device, comprising: a pressing mechanism, the pressing mechanism including a fixed tube, a tapered tube fixedly connected to one end of the fixed tube, a threaded tube fixedly connected to one end of the fixed tube, a connecting block fixedly connected to the outer surface of the fixed tube, the number of connecting blocks being three, a rotating shaft sleeved inside the connecting block, the rotating shaft being rotatably connected to the connecting block, a sleeve rod sleeved on the outer surface of the rotating shaft, the sleeve rod being fixedly connected to the rotating shaft, a limiting block provided at one end of the sleeve rod, the limiting block being fixedly connected to the sleeve rod, an inclined rod provided at one end of the sleeve rod, the inclined rod being fixedly connected to the sleeve rod, and an auxiliary mechanism provided at one end of the fixed tube, the auxiliary mechanism including an inner inclined extrusion ring.

[0006] In a preferred embodiment, the rotating shaft is provided with rotating plates at both ends inside the connecting block. The rotating plates are fixedly connected to the rotating shaft and rotatably connected to the inner wall of the connecting block. A torsion spring is sleeved on the outer surface of the rotating shaft, and the two ends of the torsion spring are fixedly connected to the outer surfaces of the connecting block and the sleeve rod, respectively.

[0007] In a preferred embodiment, the inner oblique compression ring is sleeved on the outer surface of the inclined rod, and the inner oblique compression ring is slidably connected to the inclined rod.

[0008] In a preferred embodiment, one side of the inner oblique extrusion ring is provided with a threaded ring, which is sleeved on the outer surface of the threaded tube.

[0009] In a preferred embodiment, the threaded ring is threaded to a threaded pipe, and an insert block is fitted inside the threaded ring.

[0010] In a preferred embodiment, the insert block is rotatably connected to the threaded ring, and one end of the insert block is provided with a connecting rod.

[0011] In a preferred embodiment, the connecting rod is fixedly connected to the embedded block, and the connecting rod is fixedly connected to the inner inclined extrusion ring.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention features a pressing mechanism that pushes the sealing ring into the annular sealing groove of the fuel injector, making installation of the sealing ring more convenient. After being deformed by the pressing mechanism, the sealing ring fits tightly into the annular sealing groove of the fuel injector. Simultaneously, the inner wall of the tapered tube's end also presses the installed sealing ring firmly, ensuring a better fit. Furthermore, a limiting block is provided that contacts the outer surface of the tapered tube, preventing the sealing ring from detaching from the tapered tube during movement. An auxiliary mechanism is also included to adjust the position of the inner inclined extrusion ring. This allows the inner inclined extrusion ring to compress the tilting rod during movement, causing the tilting rod to flip downwards and indirectly adjusting the position of the limiting block upwards.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 like Figures 1-4 As shown, this utility model provides a technical solution: a fuel injector sealing gasket pressing device, comprising: a pressing mechanism 1, the pressing mechanism 1 including a fixed tube 11, a tapered tube 12 fixedly connected to one end of the fixed tube 11, a threaded tube 13 fixedly connected to one end of the fixed tube 11, a connecting block 14 fixedly connected to the outer surface of the fixed tube 11, the number of connecting blocks 14 being three, a rotating shaft 15 sleeved inside the connecting block 14, the rotating shaft 15 being rotatably connected to the connecting block 14, a sleeve rod 16 sleeved on the outer surface of the rotating shaft 15, the sleeve rod 16 being fixedly connected to the rotating shaft 15, and the sleeve rod 16 being... One end is provided with a limiting block 17, which is fixedly connected to the sleeve rod 16. One end of the sleeve rod 16 is provided with an inclined rod 18, which is fixedly connected to the sleeve rod 16. One end of the fixed tube 11 is provided with an auxiliary mechanism 2, which includes an inner inclined compression ring 21. The rotating shaft 15 is placed inside the connecting block 14, and both ends are provided with rotating pieces 19. The rotating pieces 19 are fixedly connected to the rotating shaft 15 and rotatably connected to the inner wall of the connecting block 14. The outer surface of the rotating shaft 15 is sleeved with a torsion spring 101, and the two ends of the torsion spring 101 are fixedly connected to the outer surfaces of the connecting block 14 and the sleeve rod 16, respectively.

[0020] In this embodiment, by providing a tapered tube 12, and the tapered tube 12 being tapered, the sealing ring can be pushed and fitted onto the outer surface of the tapered tube 12. Firstly, the sealing ring can be enlarged, allowing it to move through the outer surface of the fuel injector. Secondly, the tapered shape of the tapered tube 12 makes it easier for the sealing ring to detach during press-fit installation. Therefore, the sealing ring can be more easily and tightly fitted with the fuel injector. Furthermore, by providing a fixed tube 11 and a threaded tube 13, and ensuring that the inner diameters of the internal circular holes of the fixed tube 11, tapered tube 12, and threaded tube 13 are consistent, the fuel injector can be fitted into the inner... The sealing ring can be easily moved to a suitable position. In addition, a limiting block 17 is provided, which can contact the outer surface of the tapered tube 12. The limiting block 17 can block the sealing ring fitted on the outer surface of the tapered tube 12, so that it will not detach from the tapered tube 12 when moving. An inclined rod 18 is provided, and the inclined rod 18 is inclined. When the inclined rod 18 is squeezed and flipped downward, it can flip and adjust the limiting block 17 under the transmission of the sleeve rod 16, so that the limiting block 17 releases the restriction of the sealing ring on the outer surface of the tapered tube 12, so that the sealing ring can detach from the tapered tube 12 and fit on the outer surface of the fuel injector.

[0021] Example 2 like Figures 1-4 As shown, the inner inclined extrusion ring 21 is sleeved on the outer surface of the inclined rod 18, and the inner inclined extrusion ring 21 is slidably connected to the inclined rod 18. One side of the inner inclined extrusion ring 21 is provided with a threaded ring 22, which is sleeved on the outer surface of the threaded tube 13 and threadedly connected to the threaded tube 13. An embedded block 23 is sleeved inside the threaded ring 22, and the embedded block 23 is rotatably connected to the threaded ring 22. One end of the embedded block 23 is provided with a connecting rod 24, which is fixedly connected to the embedded block 23 and the inner inclined extrusion ring 21.

[0022] In this embodiment, by setting an auxiliary mechanism 2, which can adjust the position of the inner inclined compression ring 21, the inner inclined compression ring 21 can compress the tilting rod 18 when it moves, so that the tilting rod 18 can be flipped and moved downward, indirectly adjusting the position of the limiting block 17 upward. Furthermore, by setting an embedding block 23, which is embedded inside the threaded ring 22, the inner inclined compression ring 21 can be pulled and moved by the transmission of the embedding block 23 and the connecting rod 24 when the threaded ring 22 rotates and moves, so that the inner inclined compression ring 21 can compress and adjust the tilting rod 18.

[0023] Working principle: like Figures 1-4As shown, in use, the threaded ring 22 can be rotated first, allowing it to rotate and move on the outer surface of the threaded tube 13. Simultaneously, the rotation of the threaded ring 22 pulls the embedded block 23 and the connecting rod 24, causing the inner oblique compression ring 21, which is fixedly connected to the connecting rod 24, to move simultaneously. The inner oblique compression ring 21 uses its internal oblique annular groove to compress the inclined rod 18, causing the inclined rod 18 to drive the sleeve rod 16 and the rotating shaft 15 to rotate inside the connecting block 14. At this time, the inclined rod 18 can flip and move downwards, while the limiting block 17 can flip and move upwards under the action of the sleeve rod 16 and the inclined rod 18. At the same time, the sleeve rod 16 can also pull and deform the torsion spring 101, causing it to generate elastic force. Then, the sealing ring is fitted onto the outer surface of the tapered tube 12, and the sealing ring is slightly pushed and moved on the outer surface of the tapered tube 12. At this time, the sealing ring is maintained... The threaded ring 22 is stabilized and reset. When the threaded ring 22 is reset, the spring force of the torsion spring 101 is slowly released, resetting the sleeve rod 16 and the tilting rod 18. This ensures that the tilting rod 18 is always in contact with the inner wall of the inner inclined extrusion ring 21, and the limiting block 17 can also approach the tapered tube 12 again until the limiting block 17 is in contact with the tapered tube 12, limiting the sealing ring on the outer surface of the tapered tube 12. Then, the fixing tube 11, the tapered tube 12 and the threaded tube 13 are sleeved on the outer surface of the fuel injector, so that the sealing ring can be moved into the annular mounting groove opened on the fuel injector. When the sealing ring is in the right position, the threaded ring 22 can be rotated again to release the contact between the limiting block 17 and the tapered tube 12. Thus, the sealing ring can be separated from the tapered tube 12 and spring back into the interior of the annular sealing groove. Then, the inner wall port of the tapered tube 12 is used to press the sealing ring tightly into the annular mounting groove of the fuel injector.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
