Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tractors, in particular to a brake internal leakage alarm device for preventing backflow. Background Art
[0002] The chassis of the tractor with wet disc brakes needs to be tested for air tightness during the running-in test. The air tightness test is mainly to check whether there is leakage in the connection parts of the container. Pressure vessels with extremely or highly toxic media or pressure vessels that are not allowed to have trace leakage in design must be tested for air tightness;
[0003] Since the air vent above the brake is small and is not normally blocked, the solution in the air tightness test pool can easily flow back into the brake after the test, causing emulsification of the brake fluid and brake failure. If it is blocked, any internal leakage of the brake cannot be detected, which can easily cause certain safety hazards. At this time, it is necessary to design an alarm device that can not only remind the staff but also prevent the liquid from flowing back into the brake. Therefore, there is room for improvement. Utility Model Content
[0004] The utility model aims to provide a brake internal leakage alarm device for preventing backflow, so as to solve the problem that the existing internal leakage alarm device proposed in the above background technology easily causes solution backflow.
[0005] To achieve the above object, the utility model provides the following technical solutions: a brake internal leakage alarm device for preventing backflow, provided with a brake body, the top end of which is connected to an anti-slip cover, the top end of which is connected to an alarm;

[0008] When using an anti-backflow brake internal leakage alarm device of the technical solution, the solution can be prevented from flowing back by installing an airbag, thereby reducing the emulsification of the brake fluid and enabling subsequent braking work to proceed smoothly. At the same time, a fixing mechanism is provided to facilitate the replacement and maintenance of the anti-slip cover by the staff.
[0009] Preferably, movable grooves are provided on both sides inside the mounting seat, and movable blocks are movably connected inside the movable grooves, and the top of the movable block is connected to a movable column, the top of the movable column is fixedly connected to the bottom end of the movable frame, and a spring is sleeved on the outer side of the movable column.
[0010] Preferably, the combination of the movable column and the movable block is in a T shape and moves inside the movable groove.
[0011] Preferably, the fixing mechanism includes a through groove provided inside the anti-slip cover. Rotating bars are connected inside the through groove. The top ends of the rotating bars are fixedly connected with rotating knobs, and the bottom ends of the rotating knobs are evenly connected with anti-slip teeth. The bottom ends of the rotating bars are connected with rotating blocks. Rotating grooves are evenly provided at the top end of the mounting plate, and the rotating grooves are movably connected with the rotating blocks.
[0012] Preferably, the cross-section of the anti-slip teeth is triangular and is arranged at equal intervals at the bottom end of the rotating knob.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0017] By installing an airbag, when gas leakage occurs, it will expand and drive the movable frame to move upward, so as to touch the pressure sensor. The pressure sensor senses the pressure and transmits the signal to the single-chip microcomputer. The single-chip microcomputer receives the information and processes and transmits it to the alarm. The alarm sounds an alarm, which can remind the staff to check.
[0018] By installing an airbag, the phenomenon of solution backflow can be prevented, thereby reducing the phenomenon of brake fluid emulsification and facilitating the subsequent smooth progress of the braking work.
[0019] Due to the elastic action of the spring, when the airbag shrinks, it can drive the movable frame to return to its original state, and its top end fits on the mounting seat, making the anti-inner-leakage structure move more flexibly.
[0020] By setting the fixing mechanism, when the anti-slip cover needs to be installed, the rotating bar is passed through the through groove, so that the anti-slip cover can be moved downward from the upper direction of the rotating knob to the top of the mounting plate. At this time, the rotating knob is rotated to be perpendicular to the through groove presented at the top of the mounting plate, so as to be in a fixed state, facilitating the staff to replace and repair the anti-slip cover.
