Fig. 2 is the three-dimensional exploded perspective view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is further described; Present embodiment is illustrative, rather than determinate, can not limit protection scope of the present invention according to following examples.
Outdoor monopod involved in the present invention is general The Cloud Terrace, in order to clearly illustrate and illustrate waterproof construction of the present invention, does not provide the overall structure of outdoor monopod in the present embodiment, is only illustrated and describes in detail with regard to the related part of waterproof construction.
A kind of waterproof construction of outdoor horizontal stage rotational axis is by The Cloud Terrace shell 1, coaxial mounted running shaft 2, The Cloud Terrace base 6 constitute in the The Cloud Terrace shell.The present invention is shaped on waterproof ring 5 outside the annular at The Cloud Terrace outer casing bottom and rotating shaft coaxle, and with the coaxial annular inner waterproofing circle 7 that is shaped on of The Cloud Terrace base pillow block, this annular inner waterproofing circle is positioned at the outer waterproof ring inner edge of annular position on The Cloud Terrace base top.One sealing skeleton 8 is installed between the pillow block of The Cloud Terrace base and The Cloud Terrace shell, and the sealing configuration of sealing skeleton and The Cloud Terrace base and The Cloud Terrace shell is:
1. between the pillow block of sealing skeleton and The Cloud Terrace base the double-lip sealing ring 3 of the bodily form one by one is installed, this double-lip sealing ring is to adopt the interference fit setting-in to go into to seal in the skeleton.
2. radially the gap 9 of moving about is arranged between the pillow block of sealing skeleton and The Cloud Terrace base, realize the sealing skeleton basis size of extruding force all around, can radially move about.
3. in the groove of sealing skeleton, be stained with water-proof mat 4 between sealing skeleton and the The Cloud Terrace shell, realization when The Cloud Terrace shell spin axis and base axis disalignment two axial lines more nearby, the The Cloud Terrace shell will press water-proof mat; Otherwise two axial lines is the distant place, and shell will gently be pressed water-proof mat.
Mounting type of the present invention is:
With double-lip sealing ring is to adopt the interference fit setting-in to go into to seal in the skeleton, then the sealing skeleton is enclosed within on the base pillow block, blocks the groove of sealing skeleton again with the The Cloud Terrace shell.(because of skeleton and base pillow block have the gap of radially moving about).After The Cloud Terrace shell card seals skeleton well, with bolt that the The Cloud Terrace shell is fastening again.Owing between base and sealing skeleton and the shell water-proof mat is arranged, and the junction point of base and the The Cloud Terrace shell mine dam that has twice to interlock, tight waterproof construction overlapped thereby formed one.When motor rotates, be fixed on master gear on the motor shaft by toothed belt around static relatively moving in a circle from gear, drive The Cloud Terrace and shell thus and do annular together and rotate.Because double-lip sealing ring is a flexible seals, the interference fit between lip and the base boss can realize motive sealing and form the twice waterproof that waterproofing effect is fairly obvious.
Working principle of the present invention and key points in design are described as follows:
Be to solve the coaxality problem of axle and shell aperture, the present invention has designed a skeleton that can move about with the axle center.This skeleton periphery is added water-proof mat, tighten skeleton with shell again, the rubber waterproof pad is arranged between skeleton and the shell, because of water-proof mat has elasticity, so can waterproof can adjust the deviation of shell and rotatingshaft herein again.Even if the cumulative error that when the assembling of part processing or complete machine, occurs like this, also can not have influence on the assembling (error will have a limit degree certainly) of The Cloud Terrace, just solve the coaxality problem of shell and rotatingshaft at an easy rate, and make the processing of axle and the assembling of structural member all become more or less freely.
For preventing that hydraulic pressure from directly impacting double-lip sealing ring, and dust foreign matter etc. enters, and designed two annular waterproof rings respectively at outer casing bottom and base top again.Because of two inside and outside waterproof rings are located at respectively on two parts; so waterproof ring can be crisscross arranged; the twice waterproof ring similarly is that the twice wall keeps off water and foreign matter outside; pressure and wearing and tearing that seal ring is hit have been reduced; thereby protected the proper functioning of double-lip sealing ring; improved the sealing effect of seal ring, can improve the working life of seal ring like this, made the The Cloud Terrace Total tune attractive in appearance again.
In order to test waterproof construction of the present invention, specially carried out the waterproofing effect test.Be about to the water slug waterproof position of elevated pressures and flow, cross or push through waterproof ring even if find water, at this moment the flow of water also can reduce greatly, therefore fully can waterproof by double-lip sealing ring, (because of self waterproof ability of seal ring just can reach more than the security level IP67).And the low amounts of water of crossing waterproof ring, can give the sulculus that stays from base inner waterproofing circle flows out, and The Cloud Terrace can not accumulate water, and advance of the present invention manifests nothing left thus.
