Embodiment Construction

[0018] The embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings; this embodiment is illustrative rather than restrictive, and the protection scope of the present invention cannot be limited according to the following embodiments.

[0019] The outdoor pan-tilt involved in the present invention is a general-purpose pan-tilt. In order to clearly show and illustrate the waterproof structure of the present invention, the overall structure of the outdoor pan-tilt is not given in this embodiment, and only the parts involved in the waterproof structure are given. illustrations and detailed descriptions.

[0020] A waterproof structure for the rotating shaft of an outdoor pan-tilt, which is composed of a pan-tilt shell 1, a rotating shaft 2 coaxially installed in the pan-tilt shell, and a pan-tilt base 6. In the present invention, an annular outer waterproof ring 5 is formed coaxially with the rotating shaft at the...

Abstract

The present invention relates to water-proof structure for an outdoor pan rotary shaft, and consists of a pan outer casing, and a rotary shaft and a pan base coaxially arranged inside the pan outer casing. Wherein, the bottom of the pan outer casing and the rotary shaft are coaxially provided with a ring type outer water-proof ring. The upper part of the pan and a pillow block of the pan base are coaxially provided with a ring type inner water-proof ring. A sealing frame is arranged between the pillow block of the pan base and the pan outer casing. A double lip sealing ring of integrated forming is arranged between the sealing frame and the pillow block of the pan base. The water-proof structure has no requirement of high assembling and processing accuracy for the rotary shaft and the outer casing due to the adoption of the double lip sealing ring and the radial roaming of the sealing frame with the strength of the pressure, and has the advantages of good water-proof property, reducing cost, improving sealing effect and reliability, simple whole structure, convenient assembling and maintenance.

Description

technical field [0001] The invention belongs to the field of front-end equipment of a security monitoring system, in particular to a waterproof structure of an outdoor pan-tilt rotating shaft. Background technique [0002] Most of the outdoor pan / tilts on the market now use trumpet-shaped rubber rings for waterproofing of their vertical and horizontal rotation axes, or waterproof structures combined with plastic frames and rubber rings. There are customer complaints caused by water entering the gimbal. Even if the O-shaped rubber ring is used as the waterproof part for the shaft, the effect is not ideal. It has high requirements for the eccentricity and coaxiality of the shaft and the housing hole, and also has high requirements for the out-of-roundness and dimensional deviation of the shaft. , so it is not suitable for the waterproof seal of the frequently rotating shaft of the pan / tilt. Contents of the invention [0003] The purpose of the present invention is to overc...
