Description

Technical Field

[0001] The utility model belongs to the technical field of brake pumps, in particular to a dustproof and oil-leakage-proof brake pump. Background Art

[0002] The brake pump, also called the brake pump, is one of the most important components in the automobile braking system. Its main function is to control the vehicle's braking system through the hydraulic system so that the vehicle can be quickly and safely decelerated or stopped during driving.

[0003] Most brake pumps have some disadvantages when used. For example, the oil reservoir on the brake pump may be hit by gravel during use, and then the oil reservoir on the brake pump will be damaged and leak oil, causing brake failure and threatening the safety of personnel. At the same time, when the brake pump is in use, fine dust particles in the air may enter the brake pump, causing the oil circuit to be blocked, affecting the normal flow of brake oil, and causing the braking performance to decline. In view of this, we propose a dust-proof and oil-leakage-proof brake pump. Utility Model Content

[0007] A fixing assembly, which is located in the fixing block and is used to fix the position of the sealing plate;

[0008] A protective shell, the protective shell is fixedly mounted on the oil reservoir of the brake pump body, and a protective plate is slidably mounted on one side of the protective shell;

[0009] A driving assembly is located on the protective shell and is used to drive the protective plate to slide.

[0010] In the present technical solution, when the brake pump is in use, the brake fluid will enter the fixed block through the oil inlet pipe, and then be filtered by the filter and then enter the brake pump body. The fine dust particles in the brake fluid will be filtered and will not enter the brake pump body. When the filter needs to be cleaned after being used for a long time, the sealing plate can be pulled outwards by the provided fixing assembly. Under the action of friction, the sealing plate will slide. When the sealing plate is not at the top of the sliding frame, under the action of the rebound force of the plurality of springs, the springs push the sliding frame to slide upward. Then the personnel can pull out the sliding frame and clean the fine dust particles filtered on the filter, so that the filter can be reused. When the cleaning is completed, the personnel reinsert the sliding frame into the fixed block, and at the same time, the plurality of springs are squeezed and contracted. When the sliding frame slides to a suitable position, the sealing plate is pushed. The position of the sealing plate can be fixed by the provided fixing assembly, and the fine dust particles on the filter can be cleaned.

[0011] By providing a protective shell and a protective plate, the oil reservoir on the brake pump body can be protected to prevent the oil reservoir on the brake pump body from being damaged by impact. When it is necessary to check the oil level in the oil reservoir on the brake pump body, the protective plate can be driven to slide to the left through the provided driving assembly. After the protective plate slides to the left, the personnel can observe the oil reservoir on the brake pump body. When the observation is completed, the protective plate can be driven to slide to the right and return to its original position through the provided driving assembly. The oil reservoir on the brake pump body can be protected and it is convenient for personnel to observe the oil reservoir on the brake pump body.

[0012] In the above technical solution, further, the fixing assembly includes:

[0013] A limit groove, which is opened in the fixed block and located at the bottom of the sealing plate. A limit column is slidably installed in the limit groove. A plurality of springs fixed to the inner wall of the limit groove are fixedly installed at the bottom of the limit column. The upper end of the limit column passes through the limit groove and extends into the sealing plate. The upper end of the limit column is plugged into the sealing plate, and one side of the limit column passes through the limit groove and extends to the outside.

[0014] In the present technical solution, when the brake pump is in use, the brake fluid will enter the fixed block through the oil inlet pipe, and then be filtered by the filter before entering the brake pump body. The fine dust particles in the brake fluid will be filtered and will not enter the brake pump body. When the filter needs to be cleaned after being used for a long time, the personnel will pull the limit column downward, and at the same time, the springs will be squeezed and contracted. When the limit column is separated from the sealing plate, the sealing plate can be pulled outward. Under the action of friction, the sealing plate will slide to the end close to the fixed plate. When the sealing plate is not at the top of the sliding frame, under the action of the rebound force of the springs, the spring pushes the sliding frame to slide upward, and then the personnel can slide The movable frame is pulled out, and the fine dust particles filtered on the filter net can be cleaned, so that the filter net can be reused. When the cleaning is completed, the personnel reinsert the sliding frame into the fixed block, and at the same time, the springs 1 are squeezed and contracted. When the sliding frame slides to a suitable position, it pushes the sealing plate, and then the sealing plate squeezes the inclined surface on the limit column, causing the limit column to slide downward, and at the same time, the springs 2 are squeezed and contracted. When the sealing plate slides to a suitable position, the limit column is no longer squeezed. Under the action of the rebound force of the springs 2, the limit column will be inserted into the sealing plate, so that the position of the sealing plate can be fixed, and the fine dust particles on the filter net can be cleaned.
