[0002] The traditional dust seal can only partially block the dust and dirt on the piston rod outside the piston cavity, but once the dust enters the piston cavity, it cannot be removed. The dirt and dust rub against the piston rod for a long time, especially Hard particles such as cast steel particles will wear the piston rod, reducing the sealing and stability of the equipment

Embodiment Construction
[0016] Do further description below in conjunction with accompanying drawing:
[0017] Such as Figure 1~2 As shown, the dust seal includes a magnetic outer ring 1, an annular skeleton 6, a clamping ring 4, a dustproof lip 2, and an auxiliary dustproof lip 3, and the magnetic outer ring 1 is fixed on the outer ring of the annular skeleton 6 Above, the clamping ring 4 is arranged at the bottom of the circular skeleton 6, the dustproof lip 2 is arranged on the upper part of the circular skeleton 6, and the dustproof inner wall of the dustproof lip 2 and the inner wall of the circular skeleton 6 On the same plane, the inner wall of the circular skeleton 6 is provided with an auxiliary dust-proof lip 3 on the same level as the magnetic outer ring 1, and the upper surface of the magnetic outer ring 1 with the circular skeleton 6 is horizontally processed with several Through-holes 5 with a rectangular cross-section, the through-holes 5 are arranged in a ring with respect to the ce...

The invention discloses a dust seal which comprises a dustproof lip, a circular annular framework and a chucking ring. The dustproof lip is installed at one side of a circular ring of the framework, the inner wall face of the dustproof lip is located on the inner wall face of the framework, the chucking ring is of a circular annular shape and is installed at the other side of the circular ring of the framework, the outer circle of the chucking ring is located on the outer wall face of the circular ring of the framework, a plurality of through holes are formed in the framework of the dust seal in an annularly arrayed mode, the through holes penetrate through the framework, and the axis of each through hole points to the center of a circle of the circular annular framework; a magnetic outer ring is further fixed to the outer side of the framework of the dust seal and the inner wall face of the magnetic outer ring is fixed to the outer wall face of the framework; an auxiliary dustproof lip is further arranged on the same plane where the inner wall of the circular annular framework and the magnetic outer ring are located and the inner diameter of the auxiliary dustproof lip is smaller than the inner diameter of the dustproof lip. Compared with a traditional dust seal, the self-cleaning performance of the dust seal is high, the dust seal is more convenient to clean, and the phenomena that due to the fact that dust is accumulated at the inner side of the dustproof lip for a long time, a piston rod is abraded and the sealing performance and the stability are reduced are avoided.
Description
technical field [0001] The invention relates to a dust seal, which belongs to the field of mechanical accessories. Background technique [0002] The traditional dust seal can only partially block the dust and dirt on the piston rod outside the piston cavity, but once the dust enters the piston cavity, it cannot be removed. The dirt and dust rub against the piston rod for a long time, especially Hard particles such as cast steel particles will wear the piston rod and reduce the sealing and stability of the equipment. Contents of the invention [0003] The purpose of the present invention is to provide a dust seal capable of automatically removing solid iron particles in the piston rod. [0004] The present invention is achieved in the following manner: [0005] A dust seal, comprising a dust-proof lip, a circular frame, and a clamping ring, the dust-proof lip is installed on the ring side of the circular frame, and the inner wall of the dust-proof lip is located on the in...
