Abstract
The utility model discloses a movable safety limiting ware, including the stopper body, offer the logical groove I and logical groove II that are used for passing the chain on the stopper body, it is good at logical groove II to lead to groove I, it passes logical groove I perpendicularly and will lead to I share elongated slot section and short groove section two parts in the groove to lead to groove II, this stopper simple structure, convenient to use, lever block to using on electric power installs the brake failure accident that prevents that this device can be fine additional, with the cooperation of stiff end tail ring limiter, can play double barreled guard action, the security is high.
Description
Technical field
The utility model belongs to Lever Blocks field, is specifically related to a kind of for the movable peace in Lever Blocks or chain blockFull stop.
Background technology
Existing chain block and Lever Blocks are all, at chain end, a stopping means is set, and prevent that chain from reaching the limit of positionAfterwards because infinite place device causes under weight pendant. This designs only onset in the time of extreme position, is working for pull/Lever BlocksIn journey, unexpected brake fade situation, can not play good preventive effect.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of safety that can play at an arbitrary position position-limiting action and flexible adjustmentStop.
For achieving the above object, the utility model provides following technical scheme: a kind of movable safety position limiter, comprises stopBody, offers on described stop body for groove I and groove II through chain, and described groove I is longer than groove II,Described groove II is vertically passed groove I and groove I is divided into elongated slot section and short groove section two parts.
Further, the elongated slot section place in described groove I is provided with two stopper slots, and two stopper slot axis parallel with groove II axis.
Further, described stop body is flattened cylindrical body, and center is provided with groove, and described groove and stopper slot are opened in limitOn the same side of position device body.
Further, described groove I is provided with top and presses inclined-plane, and pressure inclined-plane, described top is arranged on the another side of stop body.
The beneficial effects of the utility model are: this stop is simple in structure, easy to use, pull for the hand using on electric powerCucurbit, installs this device additional and can well prevent brake fade accident; Coordinate with stiff end tail ring limiter, can playDual protective effect, safe.
Brief description of the drawings
In order to make the purpose of this utility model, technical scheme and beneficial effect clearer, the utility model provides following accompanying drawing to enterRow explanation:
Fig. 1 is front view of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 1;
Fig. 4 is use view of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in the figure, the movable safety position limiter in the present embodiment, comprises stop body 5, on described stop body 5Offer for groove I 1 and groove II 2 through chain, described groove I 1 is longer than groove II 2, and described groove II 2 is vertically wornCross groove I 1 and groove I 1 is divided into elongated slot section 11 and short groove section 12 two parts. Concrete, longer groove I 1 is by grooveII 2 is divided into two parts, and elongated slot section 11 parts had both coordinated with short groove section 12 for chain 3 passes, and can play limit to chain 3 againPosition effect.
As the further improvement of such scheme, it is spacing that elongated slot section 11 places in described groove I 1 are provided with two stopper slots 13, twoGroove 13 axis parallel with groove II 2 axis; Can inlay card chain 3, prevent the problem of skidding.
In the present embodiment, described stop body is flattened cylindrical body, and center is provided with groove 4, described groove 4 and stopper slot13 are opened on the same side of stop body, and this groove 4 can coordinate with stopper slot 13, improve the inlay card effect of stopper slot 13Really.
As the further improvement of such scheme, described groove I 1 is provided with top and presses inclined-plane 14, and pressure inclined-plane, described top 14 is arranged onOn the another side of stop body, coordinate with stopper slot 13, improve the inlay card effect of stopper slot 13.
This stop is sleeved on the decline end of hoisting chain, can move to arbitrarily the position needing. Used in hoisting of hoist to operating position,Stop body is moved to the chain link near wallboard, just in case cucurbit brake apparatus lost efficacy, stop body is stuck on two wallboards and stopsChain 3 glides, and prevents that the tenesmus of weight end from causing the accident.
Finally explanation, above preferred embodiment is only unrestricted in order to the technical solution of the utility model to be described, although pass throughAbove preferred embodiment is described in detail the utility model, but it will be appreciated by those skilled in the art that can beIt is made to various changes in form and in details, and do not depart from the utility model claims limited range.
