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]
The present invention relates to a kind of sealing configuration, relate in particular to a kind of rotatingshaft sealing configuration and light fixture.
[background technique]
Usually, the light fixture with rotating mechanism for reaching the purpose of water proof and dust proof, need seal rotating mechanism in use.
To the sealing of rotating mechanism, generally adopt a slat gum circle that the rotatingshaft of rotating mechanism is carried out radial seal and realize.But the lubricant oil when rubber ring is initially installed when service time is longer is withered, is easy to cause rubber ring hardening cracking when being rotated further and damages, and rubber ring can't normally be used, and causes seal failure, can't effectively carry out water proof and dust proof.Simultaneously, rotatingshaft can't be rotated by safety and steady, cause light fixture normally to use.

Preferably, said rotatingshaft two ends offer seal groove respectively, and said seal ring is socketed in the said seal groove.
Preferably, said seal ring is the O RunddichtringO.
Preferably, said seal ring is the cylindricality seal ring, and the periphery protrusion forms the convexity of at least two annulars.
Preferably, said oil groove is the annular groove along the extending circumferentially of said rotatingshaft.
A kind of light fixture; Comprise rotating mechanism; Said rotating mechanism comprises support and wears the rotatingshaft of said support; Said rotatingshaft is rotatable with respect to said support, and said rotatingshaft two ends vertically are arranged with the seal ring that is used to seal respectively, and said rotatingshaft middle part vertically offers the oil groove that is used to store lubricant grease.
Preferably, said rotatingshaft two ends offer seal groove respectively, and said seal ring is socketed in the said seal groove.
Preferably, said seal ring is the O RunddichtringO.
Preferably, said seal ring is the cylindricality seal ring, and the periphery protrusion forms the convexity of at least two annulars.
Preferably, said oil groove is the annular groove along the extending circumferentially of said rotatingshaft.
Above-mentioned rotating mechanism and light fixture, oil groove are between the sealed at both ends circle and store lubricant grease, and lubricant grease was infiltrated into the seal ring at two ends when rotatingshaft rotated by oil groove; Seal ring is lubricated, makes that lubricant grease can not take place when seal ring rotates for a long time is withered and damage, guarantee the normal use of seal ring; Guarantee sealing effect, effectively carry out water proof and dust proof, also guarantee the safety and steady operation of rotatingshaft; Simple and reliable for structure, and convenient the installation.Simultaneously, the rotatingshaft two ends are provided with seal ring, make rotatingshaft in rotation process, occupy the centre of support more, have increased the equilibrium of forces when rotating, and make the rotatingshaft motion more steady.
[description of drawings]
Fig. 1 is the section of structure of light fixture among the embodiment;
Fig. 2 is the enlarged view at light fixture rotatingshaft shown in Figure 1 place.
[embodiment]
Below in conjunction with accompanying drawing, specific embodiments of the invention is described in detail.
Fig. 1 is the section of structure of light fixture among the embodiment, and Fig. 2 is the enlarged view at light fixture rotatingshaft shown in Figure 1 200 places.In conjunction with Fig. 1 and Fig. 2, this light fixture has rotating mechanism 10.Rotating mechanism 10 comprises support 100 and rotatingshaft 200.Rotatingshaft 200 is arranged in support 100, rotates with respect to support 100.Rotatingshaft 200 two ends vertically are arranged with the seal ring 210 that seals respectively, and rotatingshaft 200 middle part vertically offers the oil groove 220 that is used to store lubricant grease.Seal ring 210 and oil groove 220 constitute the rotatingshaft sealing configuration that rotatingshaft 200 is sealed.
Among this embodiment, rotatingshaft 200 two ends offer the seal groove 230 that is used for ccontaining seal ring 210 respectively.Seal ring 210 is the O RunddichtringO, is set in the seal groove 230, is arranged on rotatingshaft 200 two ends.
When rotatingshaft 200 relative supports 100 rotate, because rotatingshaft 200 two ends all are provided with seal ring 200, make rotatingshaft 200 in rotation process, occupy the centre of support 100 more, increased the equilibrium of forces when rotating, make motion more steady.Oil groove 220 is between sealed at both ends circle 210 and store lubricant grease; Lubricant grease is through the seal ring 210 at the lubricated two ends of infiltration during rotation; And then it is withered and damage that lubricant grease can not take place when making that seal ring 210 is long-time and rotating; Guarantee the normal use of seal ring 210, guarantee sealing effect, effectively carry out water proof and dust proof.Simultaneously, guarantee the safety and steady operation of rotatingshaft 200, simple and reliable for structure, and convenient the installation.
In other embodiments, for further sealing and guarantee that lubricant grease do not reveal, seal ring 210 is the cylindricality seal ring, is socketed in the seal groove 230.Seal ring 210 peripheries protrusion forms the convexity of at least two annulars, and is multi-sealed.Simultaneously, further make rotatingshaft 200 in rotation process, occupy the centre of support 100 more, increased the equilibrium of forces when rotating, make motion more steady.
Simultaneously, in order to guarantee enough lubricant greases, oil groove 220 is many.The oil groove 220 at two ends is near seal ring 210.
Above-mentioned rotating mechanism and light fixture, oil groove are between the sealed at both ends circle and store lubricant grease, and lubricant grease was infiltrated into the seal ring at two ends when rotatingshaft rotated by oil groove; Seal ring is lubricated, makes that lubricant grease can not take place when seal ring rotates for a long time is withered and damage, guarantee the normal use of seal ring; Guarantee sealing effect, effectively carry out water proof and dust proof, also guarantee the safety and steady operation of rotatingshaft; Simple and reliable for structure, and convenient the installation.Simultaneously, the rotatingshaft two ends are provided with seal ring, make rotatingshaft in rotation process, occupy the centre of support more, have increased the equilibrium of forces when rotating, and make the rotatingshaft motion more steady.
The above embodiment has only expressed several kinds of mode of executions of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with accompanying claims.
