Description

Technical Field

[0001] This utility model relates to the field of engine technology, and in particular to an injector pressure plate support mechanism. Background Technology

[0002] A fuel injector is a precision device used to inject fuel into the combustion chamber of an engine, and the fuel injector plate is a component used to fix the fuel injector.

[0003] Fuel injectors need to be precisely installed on the engine cylinder head to ensure accurate fuel injection angle and position. However, the existing injector pressure plate is designed to only protect and limit its side, resulting in an incomplete limiting angle. This can easily lead to low positioning accuracy of the injector, causing it to wobble or shift during operation, affecting fuel injection performance and engine performance.

[0004] Therefore, we provide an injector pressure plate support mechanism. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing an injector pressure plate support mechanism that achieves a wide limiting range and high positioning accuracy.

[0006] In view of this, the present invention provides an injector pressure plate support mechanism, including an injector mounting end and an injector inserted into the injector mounting end. An injector pressure plate for clamping is installed on the upper part of the injector. A support plate is provided above the injector pressure plate. A fixing plate is fixedly connected to the side of the support plate near the injector. Left and right extension frames are inserted into opposite ends of the fixing plate, and the left and right extension frames extend out of opposite sides of the fixing plate. Left and right telescopic strips are inserted into the two left and right extension frames away from their ends, and the left and right telescopic strips slide inside the left and right extension frames. A front and rear extension frame is installed on one side of the left and right telescopic strips. A front and rear telescopic strip is inserted into the end of the front and rear extension frame away from the left and right telescopic strips, and the front and rear telescopic strips slide inside the front and rear extension frames. Arc-shaped limiting blocks are installed at both ends of the two rear telescopic strips.

[0007] Preferably, the upper surface of the left and right stretch frames is threadedly connected with a limiting bolt, the limiting bolt extends into the interior of the left and right stretch frames, and the limiting bolt is used to fasten and limit the left and right telescopic strips.

[0008] Preferably, a spring positioning hole is provided on the upper surface of the front and rear telescopic strips, and a spring is installed inside the spring positioning hole.

[0009] Preferably, a limiting rod is installed at one end of the spring, and the limiting rod is inserted into the positioning hole of the spring.

[0010] Preferably, the upper surface of the front and rear stretch frames is provided with a plurality of limiting holes, and the limiting holes are inserted into the limiting rods.

[0011] Preferably, one of the arc-shaped limiting blocks is symmetrically equipped with a fixing block at the end away from the front and rear telescopic strips, and two fixing blocks are simultaneously equipped with fixing posts on their adjacent sides. The other arc-shaped limiting block is equipped with a rotating block at the end away from the front and rear telescopic strips. The upper end of the rotating block has a rotating hole, and the fixing post rotates inside the rotating hole.

[0012] Preferably, the upper end of the support plate and the injector pressure plate has a through bolt hole, the upper surface of the injector mounting end has the bolt hole, and the three bolt holes are internally connected. The bolt holes are threadedly connected to a fixing bolt, and the fixing bolt is threadedly connected to all three bolt holes simultaneously.

[0013] Compared with the prior art, the present invention provides an injector pressure plate support mechanism, which has the following advantages:

[0014] In this invention, before the injector is placed into the injector mounting end, the injector pressure plate is clamped on both sides of the injector, and then the support mechanism is installed. According to the size of the injector, the horizontal movement of the left and right telescopic bars is adjusted respectively. Under the guidance and support of the left and right tension frames, the stability of the horizontal movement of the left and right telescopic bars is ensured.

[0015] This utility model extends the front and rear telescopic bars. Under the guidance and support of the front and rear extension frames, the stability of the front and rear telescopic bars' forward and backward movement is ensured. At the same time, it drives the arc-shaped limit block to move towards the fuel injector. When the arc-shaped limit block is in close contact with the fuel injector, the support mechanism adjustment is completed, thus improving the device's usability.

[0016] This invention, through the fastening action of the front and rear tension frames and the arc-shaped limiting block, ensures that the injector will not shake or deviate during operation, thus guaranteeing the stability of the injector's operation.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example 1: An injector pressure plate support mechanism includes an injector mounting end 1 and an injector 2 inserted into the injector mounting end 1. The injector 2 is characterized by having an injector pressure plate 3 for clamping mounted on its upper part. A support plate 4 is positioned above the injector pressure plate 3. A fixing plate 5 is fixedly connected to the support plate 4 near the injector 2. Left and right extension frames 8 are inserted into opposite ends of the fixing plate 5, extending beyond opposite sides of the fixing plate 5. Left and right telescopic strips 9 are inserted into both ends of the left and right extension frames 8, sliding within the left and right extension frames 8. A front and rear extension frame 6 is mounted on one side of the left and right extension strips 9. A front and rear telescopic strip 10 is inserted into the end of the front and rear extension frame 6 away from the left and right telescopic strips 9, sliding within the front and rear extension frame 6. Arc-shaped limiting blocks 7 are installed at both ends of the two rear telescopic strips 10.

[0026] Before the injector 2 is placed into the injector mounting end 1, the injector pressure plate 3 is clamped on both sides of the injector 2. Then, the support mechanism is installed. According to the size of the injector 2, the left and right telescopic bars 9 are adjusted to move horizontally. Under the guidance and support of the left and right tension frames 8, the stability of the horizontal movement of the left and right telescopic bars 9 is ensured. After the left and right are adjusted to the appropriate position, the front and rear telescopic bars 10 are stretched. Under the guidance and support of the front and rear tension frames 6, the stability of the front and rear telescopic bars 10 is ensured to move forward and backward. At the same time, the arc-shaped limit block 7 is moved towards the injector 2. When the arc-shaped limit block 7 is close to the injector 2, the support mechanism adjustment is completed, which improves the application range of the device. Under the fastening action of the front and rear tension frames 6 and the arc-shaped limit block 7, the injector 2 will not shake or deviate during operation, ensuring the stability of the injector operation.

[0027] like Figure 1 - Figure 4 As shown, the upper surface of the left and right stretch frames 8 is threadedly connected with limit bolts 19, which extend into the interior of the left and right stretch frames 8 and are used to fasten and limit the left and right telescopic strips 9.

[0028] Once the left and right telescopic bars 9 have moved to the appropriate positions, based on the threaded connection between the left and right extension frames 8 and the limiting bolts 19, the limiting bolts 19 are turned clockwise to move in the direction of the left and right telescopic bars 9, thereby tightening and limiting the left and right telescopic bars 9, ensuring that the left and right telescopic bars 9 will not move horizontally, and ensuring the stability of the device operation.

[0029] like Figure 1 - Figure 4 As shown, a spring positioning hole 20 is provided on the upper surface of the front and rear telescopic strips 10, and a spring 15 is installed inside the spring positioning hole 20.

[0030] A limiting rod 14 is installed at one end of the spring 15, and the limiting rod 14 is inserted into the spring positioning hole 20.

[0031] Several limiting holes 13 are provided on the upper surface of the front and rear stretching frame 6, and the limiting holes 13 are inserted into the limiting rod 14.

[0032] When the front and rear telescopic bars 10 are stretched, press down on the limiting rod 14 so that the limiting rod 14 enters the spring positioning hole 20. At this time, adjust the front and rear telescopic bars 10 to move horizontally. When the limiting rod 14 moves to the next limiting hole 13, it enters the limiting hole 13 under the rebound action of the spring 15. At this time, the spring 15 is in normal state. Repeat the operation until the front and rear telescopic bars 10 reach the appropriate position to ensure the stability of the device operation.

[0033] Example 2: A fuel injector pressure plate support mechanism, such as Figure 1 - Figure 4As shown, a fixed block 16 is symmetrically installed on one end of the arc-shaped limiting block 7 away from the front and rear telescopic strips 10, and a fixed post 17 is installed on both sides of the two fixed blocks 16. A rotating block 1601 is installed on the other end of the arc-shaped limiting block 7 away from the front and rear telescopic strips 10. A rotating hole 18 is passed through the upper end of the rotating block 1601, and the fixed post 17 rotates inside the rotating hole 18.

[0034] When the left and right telescopic bars 9 move horizontally, based on the rotatable connection between the fixed column 17 and the rotating hole 18, the two arc-shaped limiting blocks 7 open and close around the fixed column 17 to ensure the stability of the device operation.

[0035] like Figure 1 - Figure 4 As shown, the upper end of the support plate 4 and the injector pressure plate 3 has a bolt hole 11. The upper surface of the injector mounting end 1 has a bolt hole 11, and the three bolt holes 11 are connected internally. The bolt holes 11 are threadedly connected to a fixing bolt 12, and the fixing bolt 12 is threadedly connected to the three bolt holes 11 at the same time.

[0036] After the support mechanism is adjusted, rotate the fixing bolt 12 clockwise. With the cooperation of the bolt hole 11, the support plate 4 and the injector pressure plate 3 are tightly connected. At the same time, the support plate 4 and the injector pressure plate 3 are tightly connected to the injector 1, ensuring the stability of the device during operation.

[0037] Working principle: Before the injector 2 is placed into the injector mounting end 1, the injector pressure plate 3 is clamped on both sides of the injector 2. Then, the support mechanism is installed. According to the size of the injector 2, the left and right telescopic bars 9 are adjusted to move horizontally. When the left and right are adjusted to the appropriate position, the front and rear telescopic bars 10 are stretched, which at the same time drives the arc-shaped limit block 7 to move towards the injector 2. When the arc-shaped limit block 7 is close to the injector 2, the support mechanism adjustment is completed. The fixing bolt 12 is rotated clockwise. With the cooperation of the bolt hole 11, the support plate 4 is tightly connected to the injector pressure plate 3, which in turn drives the support plate 4 and the injector pressure plate 3 to be tightly connected to the injector 1.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
