The utility model adopts a brazing connection method, wherein the supporting base plate and the base body are made of hot-rolled steel plates with low hardness, and the base body and the connecting component are U-shaped through the connecting riveted component, which has good toughness and plasticity, strong fastening, high precision and simple operation, and the through holes on both sides of the connecting component can realize the self-locking function while fixing the solenoid valve, and can also completely fix the solenoid valve related components in the U-shaped base body, completely avoiding the risk of failure such as shaking and short circuit during the movement of the equipment.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-4 The engine oil stop solenoid valve bracket assembly includes a base plate 1, a positioning groove 2 is opened in the central position of the base plate 1, a side plate 3 is fixedly installed on the top of the base plate 1, and an inner plate groove is opened on the left and right sides of the side plate 3. A connecting plate 4 is slidably installed in the inner plate groove, and a card plate 5 is fixedly installed on one side of the connecting plate 4. The card plate 5 is slidably installed in the positioning groove 2. The two card plates 5 are symmetrically arranged, and the card plate 5 is used to lock the solenoid valve.

[0025] like Figure 3 As shown, a plurality of thread grooves 6 are provided on one side of the connecting plate 4, and two connecting holes are provided on one side of the side plate 3. The thread grooves 6 and the connecting holes are used to install bolts.

[0026] like Figure 1 As shown, a circular hole 7 is opened at the center of the clamping plate 5, and the two circular holes 7 are used to fix the solenoid valve.

[0027] like Figure 4 As shown, a plurality of embedded grooves 8 are provided on one side of the card plate 5, a sliding plate 9 is slidably installed in the embedded groove 8, a same return spring 10 is fixedly installed between the sliding plate 9 and the inner wall of one side of the corresponding embedded groove 8, a trapezoidal plate 11 is fixedly installed on one side of the sliding plate 9, and a part of the trapezoidal plate 11 blocks the circular hole 7.

[0028] In this embodiment, a protective ring 12 is provided on the inner wall of the circular hole 7, and a protective pad is fixedly connected to the bottom inner wall of the positioning groove 2. The material of the protective ring 12 and the protective pad is set to rubber. The protective ring 12 and the protective pad are both set at the contact point between the solenoid valve and the bracket to reduce the direct expansion between the solenoid valve and the bracket, and increase the friction between the solenoid valve and the bracket to prevent the solenoid valve from loosening or shifting during vibration or movement.

[0029] like Figure 2 As shown, a side groove is opened on the inner wall of one side of the positioning groove 2, and a clamping plate 13 is horizontally slidably installed in the side groove. One side of the clamping plate 13 is set to an inclined surface, and multiple compression springs 14 are fixedly installed between the inner wall of one side of the side groove and the clamping plate 13. The bottom of the solenoid valve first abuts against the inclined surface of the clamping plate 13, thereby driving the clamping plate 13 to move to one side and be retracted into the side groove and compressing multiple compression springs 14. The cooperation of the compression spring 14 and the clamping plate 13 applies a rightward pressure to the solenoid valve.

[0030] like Figure 1 As shown, the edge of the base plate 1 is provided with multiple arc surfaces and protrusions, and multiple mounting holes 15 are evenly opened on the top of the base plate 1. The irregular arrangement of the edge of the base plate 1 makes it easy to place the base plate 1 in the car frame, and the mounting holes 15 are used to fix the base plate 1 with bolts.

[0031] The working principle of the present invention is as follows: the solenoid valve is placed in the positioning groove 2. When the solenoid valve is clamped into the positioning groove 2 from top to bottom, the bottom of the solenoid valve first abuts against the inclined surface of the clamping plate 13, thereby driving the clamping plate 13 to move to one side and be collected into the side groove and compressing multiple pressing springs 14. The solenoid valve is exerted with a rightward pressure through the cooperation of the pressing spring 14 and the clamping plate 13, and the side plate 3 limits the solenoid valve, thereby clamping and fixing the solenoid valve in the left and right directions, and moving the two clamping plates 5 toward the side close to each other, so that the solenoid valve The two ends are respectively inserted into the corresponding circular holes 7. When the solenoid valve passes through the circular hole 7, it first abuts against the inclined surface of the trapezoidal plate 11, thereby driving multiple trapezoidal plates 11 to move to the side away from the center of the circular hole 7 and compressing the reset spring 10, thereby releasing the trapezoidal plate 11 from blocking the circular hole 7. When one end of the solenoid valve passes through the circular hole 7, the reset spring 10 drives the sliding plate 9 and the trapezoidal plate 11 together to approach the solenoid valve, clamping the solenoid valve, thereby clamping the solenoid valve in the front and rear directions, and finally locking the connecting hole and the threaded groove 6 by bolts to fix the clamping plate 5.

The preferred embodiments do not describe all details in detail, nor do they limit the present invention to the specific embodiments described. Obviously, many modifications and variations are possible based on the contents of this specification.
