As shown in fig. 1-2, the implementation of the invention comprises a liquid storage filling cover 1, an oil inlet rubber sealing ring 3, a vent rubber sealing ring 4, a sealing support 2 and a floating block 5, wherein the sealing support 2 and the floating block 5 are both arranged in the liquid storage filling cover 1, the floating block 5 is sleeved on the bottom of the sealing support 2 and is connected with the vent rubber sealing ring 4, the end face of the bottom of the sealing support 2 is connected to the end face of an oil inlet 6 of a liquid storage tank through the oil inlet rubber sealing ring 3, and the liquid storage filling cover 1 is arranged on the oil inlet 6 of the liquid storage tank.
As shown in fig. 3, the inner peripheral surface of the liquid storage cover 1 is provided with an internal thread 11, and the internal thread 11 is connected with an external thread screwed on the outer peripheral surface of the liquid storage tank oil inlet 6 to form threaded fit; in actual use, a gap exists between the liquid storage filling cover 1 and the liquid storage tank oil inlet 6 in a threaded fit mode, and external atmosphere can enter the gap.
As shown in fig. 2 to 3 and 7 to 8, the seal holder 2 includes a cover plate 21 and a guide bar 22 fixedly coupled to the center of the bottom end surface of the cover plate 21, and the cover plate 21 and the guide bar 22 are integrated by injection molding. The top end surface of the cover disc 21 is connected to the inner top surface of the liquid storage cover 1, a strip-shaped ventilation groove 24 is formed in the top end surface of the cover disc 21, the ventilation groove 24 is communicated with a middle ventilation hole 25, and the periphery of the bottom end surface of the cover disc 21 is in sealing connection with the end surface of the liquid storage tank oil inlet 6 through an oil inlet rubber sealing ring 3; the cover plate 21 is centrally provided with a middle vent hole 25 extending into the top of the guide bar 22, and the peripheral surface of the top of the guide bar 22 is provided with side vent holes 26 communicating with the middle vent hole 25.
An annular boss 23 is fixed on the bottom end face of the cover disc 21, a hook part is arranged at the bottom end of the annular boss 23, and an oil inlet rubber sealing ring 3 is sleeved outside the annular boss 23 and axially supported and limited through the hook part. The hook part prevents the oil inlet rubber seal ring from falling off when unscrewing the liquid storage filling cover. In practice, two symmetrical side vent holes 26 are considered, and are formed by injection molding after the insertion of a die core rod, and interference with the annular boss 23 occurs during the core rod withdrawal process. The annular boss 23 is thus designed to be composed of two arcuate bodies symmetrically arranged.
The thickness of the cover disk 21 is less than or equal to the width of one thread of the internal thread 11 of the liquid storage cover 1, so that the cover disk 21 is screwed into the liquid storage cover 1 along the internal thread 11.
As shown in fig. 2-3 and fig. 9-11, the floating block 5 is movably sleeved outside the guide rod 22, a radial elastic buckling structure 27 for supporting the floating block 5 in the axial direction and preventing the floating block 5 from falling is arranged at the bottom end of the guide rod 22, and the bottom end of the floating block 5 is supported on the radial elastic buckling structure 27 to prevent the floating block 5 from falling due to the action of gravity; the upper end of the floating block 5 is provided with a protruding cylinder 54 extending along the axial direction, the peripheral surface of the protruding cylinder 54 is provided with an outer flange 55, and the vent rubber sealing ring 4 is sleeved outside the protruding cylinder 54 and is axially fixed through the outer flange 55.
The vent grooves 24 extend from the middle vent holes 25 to the edge of the cover plate 21 in the radial direction, so that the smoothness of the liquid flow in the liquid storage tank is ensured.
As shown in fig. 3-4, the floating block 5 is mainly formed by fixing and welding an upper portion 51 and a lower portion 52, three reinforcing ribs 53 are respectively arranged in the upper portion 51 and the lower portion 52, and the inner cavities of the upper portion 51 and the lower portion 52 are divided into three subchambers by the reinforcing ribs 53. The arrangement of the subchambers and the reinforcing ribs 53 inside the upper and lower portions 51 and 52 is symmetrical up and down.
In specific implementation, the upper part 51 and the lower part 52 of the floating block are welded together through hot plate welding or ultrasonic welding, and the reinforcing ribs 53 of the upper part 51 and the lower part 52 are welded so that a plurality of subchambers are correspondingly welded, thereby achieving the sealing and firmly adhering effect.
The assembly flow of the mechanism assembly of the invention is as follows:
the sealing support 2 is screwed into the liquid storage filling cover 1 through a screw thread gap of the liquid storage filling cover 1, then the floating block 5 provided with the vent rubber sealing ring 4 is assembled on the guide rod 22, and finally the oil inlet rubber sealing ring 3 is assembled on the annular boss 23 of the sealing support 2.
When the device works, the floating block 5 is positioned in the oil inlet 6 of the liquid storage tank, and the oil inlet 6 of the liquid storage tank is filled with oil. When the automobile encounters a bumpy road or the automobile starts to brake, the oil in the oil inlet 6 of the liquid storage tank can surge to the port of the oil inlet 6 of the liquid storage tank by vibration, and then the oil impacts the floating block 5.
Because the integral density of the floating block 5 is less than the oil density, the floating block 5 can move upwards along the axial direction of the guide rod 22 under the impact and buoyancy actions, and the technical effect that the greater the impact force is, the better the oil resistance sealing effect is achieved through the following modes:
as shown in fig. 5, when the floating block 5 does not receive the oil impact in the oil inlet 6 of the liquid storage tank, the vent rubber seal ring 4 is located below the side vent 26, and at this time, the side vent 26 is not sealed. The outside atmosphere enters the vent groove 24 from the screw thread clearance between the liquid storage filling cover 1 and the liquid storage tank oil inlet 6, and then enters the inside of the liquid storage tank oil inlet 6 after sequentially entering the middle vent hole 25 and the side vent holes 26 through the vent groove 24, so that the gas circulation can be realized.
As shown in fig. 6, under the impact of oil in the oil inlet 6 of the liquid storage tank received by the floating block 5, the floating block 5 moves up to the top of the guide rod 22, and the vent rubber sealing ring 4 is sealed at the side vent 26.
The outside atmosphere enters the vent groove 24 from the screw thread gap between the liquid storage filling cover 1 and the liquid storage tank oil inlet 6, and then enters the middle vent hole 25 and the side vent holes 26 in sequence through the vent groove 24, and then is blocked by the vent rubber sealing ring 4 and cannot enter the inside of the liquid storage tank oil inlet 6, so that gas cannot circulate.
