Detailed Description

The utility model will be further described in detail with reference to the drawings and the detailed description below, in order to further understand the features and technical means of the utility model and the specific objects and functions achieved.

Referring to fig. 1 to 3, a novel waterproof structure switch shell comprises a switch shell 1, one axial end of the switch shell 1 is provided with a cavity 11, the cavity 11 does not penetrate through the switch shell 1, one end of the switch shell 1 far away from the cavity 11 is close to the outer side and is provided with a circle of protruding block 12, the inner side of the protruding block 12 is provided with a circle of sealing ring 2, the outer side of the sealing ring 2 is in butt joint with the inner side of the protruding block 12, and one end of the sealing ring 2 close to the switch shell 1 is in butt joint with the switch shell 1.

When carrying out waterproof installation to switch housing 1, the part is installed at the one end that switch housing 1 had lug 12 this moment, the outside and the sealing washer 2 butt of part to with sealing washer 2 promote towards one side of lug 12, so make the part can not guarantee the water-proof effects through the compactness with the butt of switch housing 1 alone when installing, the contact between part and the sealed pad is equivalent to having increased round annular area of contact, thereby further increased waterproof nature, and the sealed pad is kept away from the one end top of part on lug 12, further improved the leakproofness and is waterproof effects promptly.

Through setting up lug 12 and sealing washer 2, when installing switch shell 1 back, when beginning the installation part, the part is located the outside and the sealing washer 2 butt of the outer one end of switch shell 1 to with the outside one end of sealing washer 2 promotion with lug 12 butt, thereby the part is located the sealing treatment has also been accomplished to the outer one end of switch shell 1, has increased area of contact promptly, has also used sealing washer 2 to seal, and then has improved the water-proof effects.

Referring to fig. 3, the sealing ring 2 is a U-shaped rubber ring 21, the outer diameter of the rubber ring 21 is the same as the inner diameter of the protruding block 12, and the U-shaped opening of the U-shaped rubber ring 21 faces the switch housing 1.

Through setting up the external diameter of rubber circle 21 the same with the internal diameter of lug 12 to can laminate more when placing rubber circle 21 in lug 12 department, rubber circle 21 can not drop easily when using like this, and use the rubber circle 21 of U type, the rubber circle 21 of U type is convenient for compress, has good corrosion-resistant and wear resistance moreover.

As shown in fig. 3, the end of the switch housing 1 remote from the cavity 11 is further provided with a first communication hole 13, and the first communication hole 13 and the switch housing 1 are coaxially arranged.

The first communication hole 13 is further provided with a second communication hole 14 near one end of the cavity 11, the second communication hole 14 and the first communication hole 13 are coaxially arranged, the diameter of the second communication hole 14 is smaller than that of the first communication hole 13, and the second communication hole 14 and the cavity 11 are communicated.

The diameters of the first communication hole 13 and the second communication hole 14 are different, and the diameter of the second communication hole 14 is smaller than that of the first communication hole 13, so that the first communication hole and the second communication hole form a step-shaped opening into the cavity 11, and therefore, when the part is installed, the contact surface is increased, and the installation is firmer.

Referring to fig. 2, the end of the switch housing 1 provided with the protruding block 12 is further provided with a plurality of mounting holes 15, the mounting holes 15 are disposed on the inner side of the sealing ring 2, and the mounting holes 15 are disposed annularly around the outer side of the second communication hole 14.

When the part is required to be installed, the hole on the part is aligned with the installation hole 15, and the installation hole 15 is a threaded hole, so that the part is firmly installed on the inner side of the sealing ring 2 through the bolt, and the outer side of the part is abutted with the inner side of the sealing ring 2.

Referring to fig. 1, the switch housing 1 is cylindrical.

The cylindrical switch shell is more round, and people can not be injured when colliding.

According to the application, the projection 12 and the sealing ring 2 are arranged, when the switch shell 1 is installed, and a part is positioned outside one end outside the switch shell 1 and is abutted with the sealing ring 2, and the sealing ring 2 is pushed to be abutted with the projection 12, so that the part is positioned at one end outside the switch shell 1, and the sealing treatment is completed, namely, the contact area is increased, and the sealing ring 2 is used for sealing, so that the waterproof effect is improved.
