Description

Technical Field

[0001] The utility model relates to the technical field of fuel injector accessories, in particular to the technical field of a fuel injector pressure plate. Background Art

[0002] The fuel injector is an important part of the fuel supply system of the diesel engine. The fuel injector pressure plate is a component in the engine. The fuel injector pressure plate is fixed to the engine cylinder head by bolts and pressed against the fuel injector, thereby pressing the fuel injector against the engine cylinder head to prevent the fuel injector from loosening.

[0003] Most of the injector pressure plates currently used are too large, inconvenient to arrange and install, and are prone to the hidden danger of air leakage due to the inability to compress the injector. With the demand for increasingly compact engine appearance, the existing injector pressure plates cannot meet the usage requirements.

[0004] In order to solve the problems raised in the background technology, for example, application number CN201720540223.6 discloses an engine injector pressure plate, comprising: a pressure plate body, a first supporting surface protruding from the rear end of the bottom surface of the first support surface; a U-shaped bayonet, which is arranged at the front end of the pressure plate body, and the opening of the U-shaped bayonet faces forward; the bottom surfaces of the two side walls of the U-shaped bayonet are second supporting surfaces; the second supporting surface protrudes from the bottom surface of the pressure plate body; and a through hole, which is arranged in the middle of the pressure plate body, and the upper end of the through hole is provided with a chamfer for cooperating with a spherical washer, the first supporting surface is pressed on the engine cylinder head and the second supporting surface is pressed on the clamping surface of the injector, and then the chamfer of the through hole cooperates with the spherical washer to ensure that the direction of the tightening force generated by the bolt is parallel to the axis of the injector, thereby reducing the hidden danger of air leakage caused by failure to tighten the injector. However, this structure still has the following defects:

[0005] Although this structure ensures the secure installation of the injector by cooperating with chamfers and spherical washers, the injector is still prone to positional displacement due to the vibration of the diesel engine during long-term use, which in turn causes the pressure plate to be unable to press the injector, resulting in the hidden danger of injector leakage.

[0006] In order to solve the problems raised in the above-mentioned technology, for example, application number CN202121320942.X discloses an injector pressure plate, comprising a pressure plate body, a clamping portion connected to one side of the pressure plate body, and a tapered groove is provided at the middle position of the front of the pressure plate body, a positioning bolt is inserted into the interior of the tapered groove, and a fitting groove is provided at the lower position of the interior of the pressure plate body through one-piece injection molding, and a combination frame is built into the interior of the fitting groove, and the combination bracket is installed in the clamping portion. When the entire pressure plate is clamped on the injector through the clamping portion, the arc-shaped spacer and the transverse spacer will use their own convex structure to effectively increase the friction between the entire pressure plate and the injector, reduce the number of times the injector slips out in the later stage, ensure the stability of the connection between the entire injector and the pressure plate, so that the pressure plate can always press the injector tightly, thereby improving work efficiency. However, this structure still has the following defects:

[0007] The clamping portion of this structure cannot be adjusted and moved, which makes it impossible to clamp injectors of different sizes, and has low practicality. Summary of the Invention

[0008] The purpose of the utility model is to solve the problems in the prior art and to provide an injector pressure plate, which can freely adjust the distance between the clamping components, thereby clamping injectors of different sizes and having greater practicality.

[0009] The top end of the fixing plate is connected to the fixing plate by a threaded connecting strip which is cooperatively connected with the fixing plate, and the fixing plate is connected to the fixing plate by a threaded connecting strip.

[0010] Preferably, a threaded hole is provided on the pressure plate body, a fastening bolt is threadedly installed in the threaded hole, and the pressure plate body is connected to the cylinder head of the engine through the fastening bolt passing through the threaded hole.

[0011] Preferably, a washer is provided at the connection between the fastening bolt and the pressure plate body.

[0012] Preferably, the clamping block has a V-shaped structure, and a rubber pad is provided on the inner side of the clamping block.

[0013] Preferably, the outer surface of the rubber pad is provided with anti-slip textures.

[0014] Preferably, a support rod is vertically provided above the two clamping blocks, and an auxiliary pressing plate is connected above the support rod.

[0015] Preferably, the inner side surface of the auxiliary pressing plate is an arc structure.

[0016] Beneficial effects of the utility model:

[0017] 1. The present invention can clamp fuel injectors of different sizes by cooperating with the moving assembly and the clamping assembly. When the fuel injector is placed between the two clamping assemblies, the rotating handle is rotated clockwise or counterclockwise, so that the rotating handle drives the threaded rod to rotate forward and reverse, thereby driving the two moving blocks to move closer or further away from each other. In the process of moving the moving blocks closer or further away from each other, the clamping blocks are driven closer or further away from each other, thereby clamping fuel injectors of different sizes. This has higher working efficiency and greater practicality, and solves the problem of the clamping part being unable to adjust and move, which leads to the inability to clamp fuel injectors of different sizes and low practicality.

[0018] 2. The present invention provides a rubber pad with anti-skid patterns. The rubber pad can increase the friction between the clamping block and the injector, thereby improving the firmness of the connection between the pressure plate body and the clamping block. The anti-skid patterns on the outer surface of the rubber pad can further increase the friction between the clamping block and the injector, making it difficult for the injector to move even after long-term use.

[0019] 3. The utility model provides an auxiliary pressing plate so that the movable block can synchronously drive the auxiliary pressing plate to move during the movement, thereby pressing and positioning both sides of the injector, thereby improving the stability of the injector during the pressing process, increasing the pressing effect of the pressing plate body on the injector, and reducing the hidden danger of air leakage caused by failure to press the injector.

By rotating the rotating handle 32 clockwise or counterclockwise, the rotating handle 32 drives the threaded rod 31 to rotate forward and backward, thereby driving the two moving blocks 33 to move closer to or farther away from each other. In the process of moving closer to or farther away from each other, the moving blocks 33 drive the clamping blocks 42 to move closer to or farther away from each other, thereby clamping injectors of different sizes.
