the thread elastic ring comprises an upper thread ring, a lower thread ring is arranged below the upper thread ring, and a thread inner ring is formed between the upper thread ring and the lower thread ring;

the lower thread ring is not in the same straight line with the axis of the arc transition area.

Further, the upper port is circular.

Further, the aperture of the upper port is less than or equal to 40mm and greater than or equal to 20mm.

Further, the thread inner ring is a circular arc-shaped transition surface.

Furthermore, the depth range of the clamping groove is 4-8mm.

Further, the lower port is a long round hole.

Furthermore, the dustproof sleeve is made of soft rubber.

Further, the included angle between the whole dustproof sleeve and the horizontal plane is larger than 45 degrees and smaller than 90 degrees.

Compared with the prior art, the utility model the advantage lie in: the utility model discloses the basis of crossing the line or guaranteeing original motion sets up the dirt proof boot in the installing port position, but the dirt proof boot has elastic flexibility, on leaking the installing port outward through the draw-in groove installation, can effectually prevent that the installing port from leaking out and advance muddy water, makes the brake position seem more pleasing to the eye.

fig. 4 is a bottom view of the present invention.

As shown in the figure: 1. An upper port; 2. a lower port; 3. a threaded elastic ring; 4. an arc-shaped transition zone; 5. a card slot; 6. an upper thread ring; 7. a lower thread ring; 8. and (4) a threaded inner ring.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Examples

As shown in fig. 1-4, an electric vehicle mounting port dust-proof sleeve structure comprises a dust-proof sleeve body, wherein an upper port 1 and a lower port 2 are respectively arranged at the upper end and the lower end of the dust-proof sleeve body, a threaded elastic ring 3, an arc transition area 4 and a clamping groove 5 are sequentially arranged between the upper port 1 and the lower port 2 from top to bottom, the upper port 1 is used for exposing a service brake plate, and the lower port 2 is used for exposing the bottom end of the brake plate. The thread elastic ring 3 can freely stretch out and draw back under the action of external force, normal use is not influenced, the arc transition area 4 has a certain angle and is consistent with the movement track of the brake plate, and the clamping groove 5 is used for being clamped with the mounting port.

The thread elastic ring 3 comprises an upper thread ring 6, a lower thread ring 7 is arranged below the upper thread ring 6, a thread inner ring 8 is formed between the upper thread ring 6 and the lower thread ring 7, and the dustproof sleeve has better elasticity in the motion range of the brake disc by arranging the upper thread ring 6 and the lower thread ring 7.

The lower thread ring 7 and the axis of the arc transition area 4 are not on the same straight line, and a certain included angle is formed between the whole dustproof sleeve and the horizontal plane.

As shown in figure 1, the dustproof cover is made of soft rubber, has certain resilience and does not influence normal use.

As shown in figure 1, the included angle between the whole dustproof sleeve and the horizontal plane is more than 45 degrees and less than 90 degrees, so that the movement condition can be met.

As shown in fig. 2, the threaded inner ring 8 is a circular arc transition surface.

As shown in figure 2, the depth range of the clamping groove 5 is 4-8mm, and the height of the clamping groove is consistent with that of the assembly surface, so that the dustproof sleeve can be conveniently installed and clamped.

As shown in fig. 3, the upper port 1 has a circular shape.

As shown in fig. 3, the aperture of the upper port 1 is 40mm or less and 20mm or more.

As shown in fig. 4, the lower port 2 is an oblong hole.

In a specific use:

before the brake pedal is used, the dustproof sleeve is sleeved into a brake system from the upper side of the brake pedal and is clamped at the position of a brake mounting opening through the clamping groove 5, the brake pedal is exposed from the upper port 1, and the lower end of the brake is exposed through the lower port 2.
