Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with attached drawing pair
The utility model is further detailed.
As Figure 1-Figure 5, a kind of concealed sliding block locking system provided by the embodiment of the utility model, including column 1
With sliding block, column 1 is hollow, and sliding block is arranged in column 1, is slidably connected with column 1.Sliding block includes slider body 2, blocking element
3 are connect with slider body 1 by main shaft 5 with tripper 4, blocking element 3, and blocking element 3 includes locking end 31, locking end 31
It is directed toward obliquely downward, rack gear 11 is set on the inside of column 1, locking end 31 is stuck in rack gear 11, realizes locking, and the setting of tripper 4 exists
It on blocking element 3, is rotatablely connected with blocking element 3, tripper 4 includes support portion 41 and control unit 42, and support portion 41 can be with
Rack gear 11 connects, and limiting device 32 is arranged in blocking element 3, and limiting device 32 is arranged on the motion profile of tripper 4,
The turned position of tripper 4 is limited, when tripper 4 and limiting device 32 contact, support portion 41 is directed inclined upwardly.Limit dress
Holddown spring 33 is installed, blocking element 3 is connect by pre-tightening apparatus with slider body 2, and pre-tightening apparatus is preloading spring 6.
Connecting hole, the settable drag-line of connecting hole is arranged in control unit 42, and drag-line is stretched to outer by the through-hole 21 of slider body 2
Portion.Secondary sliding block 22, the setting of column 1 and the matched sliding slot 12 of secondary sliding block 22 is arranged in 2 side of slider body.Slider body 2 and column 1
Pin hole 23 is arranged in corresponding position.Main shaft 5 and 2 grafting of slider body, groove 51 perpendicular to the axis, groove is arranged in 5 surface of main shaft
Fixed plate 7 is inserted into 51, fixed plate 7 is detachably connected with slider body 2, such as is bolted.
Utility model works principle is as follows:
Top stick 8 is used to support hoistable platform, and when sliding block, which is located at, to be risen in column 1, tripper 4 refers to blocking element 3
Oliquely downward, blocking element 3 and rack gear 11 are clamped, and are risen hour rack 11 and are not interfered sliding block to rise, and blocking element 3 does not work,
Due to the effect of preloading spring 6, locking end 31 is close to always rack gear 11, and when unexpected glide occurs in sliding block, locking end 31 can be inserted
Enter and realizes latch functions in rack gear 11.
When needing to fall sliding block, sliding block is slightly risen, by manually pulling drag-line, rotates tripper 4, support
Portion 41 is directed inclined upwardly, and tripper 4 can open blocking element, disengages it from the locking with rack gear 11.Under sliding block continues
Drop, due to the presence of tripper 4, blocking element 3 will not again with 11 locking of rack gear, and since tripper 4 is obliquely installed,
It will not be stopped by rack gear 11 sliding block decline.
The effect of limiting device 32 is to prevent tripper 4 from rotating excessively, to not have the work for opening blocking element 3
With holddown spring 33, which acts on, to be to reduce the gap between tripper 4 and column 1, avoids sliding block shaking, and then prevent
Blocking element 3, which is mistakenly inserted rack gear 11, influences decline.
It is above that certain exemplary embodiments of the utility model are only described by way of explanation, undoubtedly, for
Those skilled in the art can be with a variety of different without departing from the spirit and scope of the utility model
Mode is modified described embodiment.Therefore, above-mentioned attached drawing and description are regarded as illustrative in nature, and should not be construed as
Limitation to the utility model claims protection scope.
