Problems solved by technology

However, when the rubber ring is used for a long time, the lubricating oil in the initial installation is dry, and it is easy to cause the rubber ring to harden and crack and be damaged when it continues to rotate, so that the rubber ring cannot be used normally, causing the seal to fail, and cannot be effectively waterproof and dustproof.
At the same time, it also makes the rotating shaft unable to rotate safely and smoothly, resulting in the failure of the normal use of the lamp

Embodiment Construction

[0019] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] figure 1 is a structural sectional view of a lamp in an embodiment, figure 2 yes figure 1 An enlarged view of the axis of rotation 200 of the luminaire shown. combine figure 1 with figure 2 , the lamp has a rotating mechanism 10. The rotating mechanism 10 includes a bracket 100 and a rotating shaft 200 . The rotating shaft 200 passes through the bracket 100 and rotates relative to the bracket 100 . Both ends of the rotating shaft 200 along the axial direction are respectively sleeved with sealing rings 210 for sealing, and the middle part of the rotating shaft 200 along the axial direction is provided with an oil groove 220 for storing lubricating grease. The sealing ring 210 and the oil groove 220 constitute a rotating shaft sealing structure for sealing the rotating shaft 200 .

Abstract

The invention relates to a rotary mechanism and a lamp. The rotary mechanism comprises a support and a rotary shaft penetratingly arranged on the support, and the rotary shaft can rotate relative to the support. The rotary mechanism is characterized in that sealing rings for sealing are sleeved at two ends along the axial direction of the rotary shaft respectively, and a grease tank for storing lubricating grease is arranged on a middle portion along the axial direction of the rotary shaft. The grease tank is positioned between the sealing rings at the two ends and stored with the lubricating grease, and when the rotary shaft rotates, the lubricating grease permeates to the sealing rings at the two ends through the grease tank to lubricate the sealing rings, so that damages of the sealing rings caused by drying up of the lubricating grease when the sealing rings rotate for a long time can be avoided, normal use of the sealing rings can be guaranteed, sealing effects can be guaranteed, water proofing and dust proofing can be realized effectively, and safe and stable operation of the rotary shaft can be guaranteed. The sealing structure for the rotary shaft is simple and reliable in structure and convenient to mount. In addition, the two ends of the rotary shaft are both provided with the sealing rings, so that the rotary shaft can be positioned in the middle of the support as much as possible during rotation, and force balance is facilitated during rotation to enable the rotary shaft to move more stably.

Description

【Technical field】 [0001] The invention relates to a sealing structure, in particular to a rotating shaft sealing structure and a lamp. 【Background technique】 [0002] Usually, when a lamp with a rotating mechanism is in use, the rotating mechanism needs to be sealed in order to achieve the purpose of waterproof and dustproof. [0003] The sealing of the rotating mechanism is generally achieved by radially sealing the rotating shaft of the rotating mechanism with a rubber ring. However, when the rubber ring is used for a long time, the lubricating oil in the initial installation is dry, and it is easy to cause the rubber ring to harden and crack and be damaged when it continues to rotate, so that the rubber ring cannot be used normally, causing the seal to fail, and cannot be effectively waterproof and dustproof. . Simultaneously, it also makes the rotating shaft unable to rotate safely and smoothly, causing the lamp to be unable to use normally. 【Content of invention】 ...
