Description
Technical field
The utility model relates to a kind of secondary self-locking structures of caravan overturning platform.
Background technique
Existing apartment vehicle mostly uses manual roller steel wire rope structure for the overturning of platform in the market, main to slow down comprising common
Machine, reel, guide wheel, wirerope, hinge, wherein platform is by wirerope, then is oriented to by guide wheel and is connect with reel, speed reducer and
Reel is connected, and rotates speed reducer manually and drives spool turns, to realize the overturning of platform；Although speed reducer is in manual rotation process
In play the role of amplifying moment and labour-saving, but it can not achieve self-locking, generally require to inhibit overturning flat by the strength of people
For platform in the unexpected whereabouts of switching process, it is very unsafe for overturning in this way to operating platform, there is very big security risk.
Utility model content
The utility model makes improvement for the above-mentioned problems of the prior art, i.e., skill to be solved in the utility model
Art problem is to provide a kind of secondary self-locking structure of caravan overturning platform, has double insurance, structure is simple, easy to use.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is: a kind of caravan overturning platform it is secondary from
Lock construction, including pedestal are provided with the output shaft that worm gear mechanism speed reducer drives rotation on the pedestal, described defeated
The reel of synchronous rotation is provided on shaft, one end of the reel is provided with the ring baffle that outer diameter is greater than outside barrel diameter, institute
It states and is evenly equipped with several limit holes on baffle, telescopic bolt is additionally provided on the pedestal, the bolt is for being inserted into limit
In hole.
Further, it is provided with a mounting base on the pedestal, one is provided in the mounting base for entangling bolt
Sleeve is provided in the sleeve and covers the spring of bolt ejection sleeve-shaped state on bolt and remain, after the bolt
End is provided with drawstring.
Further, the active grab for holding drawstring is provided on the pedestal.
Further, it is provided at least one annular partition on the reel, so that the non-interfering winding of reel energy is more
Root hawser.
Further, the reel side is provided with winding-resisting device, and the winding-resisting device includes multiple hawser being allowed to wear one by one
The box crossed.
Compared with prior art, the utility model has the following beneficial effects: the present apparatus includes duplicate protection, first protects again
Shield is the self-locking function of worm-gear speed reducer, i.e., only worm screw can drive worm gear to rotate, and worm gear is to be unable to drive snail in turn
Bar rotation, that is, it realizes self-locking；Second protects again to be unfolded and withdrawing extreme position with brake pin aperture is equipped in platform, makes platform
It can be in stop position safe self-locking.
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Detailed description of the invention
Fig. 1 is the construction schematic front view of the utility model embodiment.
Fig. 2 is the construction diagrammatic top view of the utility model embodiment.
Fig. 3 is the construction diagrammatic side view of the utility model embodiment.
Fig. 4 is the organigram of latch structure in the utility model embodiment.
In figure: 1- pedestal, 2- worm gear mechanism speed reducer, 21- output shaft, 3- reel, 31- partition, 32- are antiwind
Device, 4- baffle, 41- limit hole, 5- mounting base, 51- sleeve, 52- spring, 53- drawstring, 54- active grab, 6- bolt.
Specific embodiment
Embodiment one: as shown in figures 1-4, a kind of secondary self-locking structure of caravan overturning platform, including pedestal 1, the bottom
It is provided with the output shaft 21 that worm gear mechanism speed reducer 2 drives rotation on seat, synchronous turn is provided on the output shaft
Dynamic reel 3, one end of the reel is provided with the ring baffle 4 that outer diameter is greater than outside barrel diameter, if being evenly equipped on the baffle
A limit hole 41 is done, telescopic bolt 6 is additionally provided on the pedestal, the bolt is for being inserted into limit hole.
In the present embodiment, it is provided with a mounting base 5 on the pedestal, one is provided in the mounting base for entangling bolt
Sleeve 51, be provided in the sleeve and cover the spring 52 of bolt ejection sleeve-shaped state on bolt and remain, it is described
Bolt rear end is provided with drawstring 53.
In the present embodiment, the active grab 54 for holding drawstring is provided on the pedestal.
In the present embodiment, at least one annular partition 31 is provided on the reel, so that reel non-interfering can twine
Around more hawsers.
In the present embodiment, the reel side is provided with winding-resisting device 32, and the winding-resisting device includes multiple hawsers one that allow
One box passed through.
In use, pulling active grab, bolt is pulled out out of limit hole on baffle, opens speed reducer, spool turns；
Pulling active grab makes its reset, and bolt is inserted into the limit hole on baffle, secondary self-locking to the rotation realization of reel, avoids subtracting
Fast machine damage cannot be self-locking.
The above is only the preferred embodiment of the present invention, it is all done according to present utility model application the scope of the patents it is equal
Deng variation and modification, it should all belong to the covering scope of the utility model.
