Abstract
The utility model discloses a kind of handwheel positive stop strip structure, including handwheel, casing, screw, metal insert, positive stop strip b and steel wire rope, metal insert is fixed on positive stop strip b end, and screw is threadedly coupled with metal insert, and steel wire rope is integrally posted and fixed with positive stop strip b and is connected.Superiority：Structure of the present utility model adds the screw strength of positive stop strip, once and ensure positive stop strip be broken, can easily be dismantled.
Description
(1) technical field：
The utility model belongs to electric device for valve technical field, particularly a kind of handwheel positive stop strip structure.
(2) background technology：
It is generally used for controlling the electric device for valve of electromechanical equipment to be provided with man-operated mechanism, so that electric device is in dead electricity
The opening and closing completed to valve can be manually operated under state.The man-operated mechanism of usual electric device is equipped with operation
Handwheel, and handwheel is connected by positive stop strip with casing.Therefore, reliable positive stop strip structure reasonable in design is in electric device for valve
It is considerable.
In known technology, the installation of positive stop strip and dismounting pattern are usually：As shown in figure 1, handwheel 1 is coordinated by gap
Load casing 3, it is square looping pit that a section is formd between such handwheel 1 and casing 3.Positive stop strip 2 is passed through into gap
Coordinate and load along looping pit direction.So positive stop strip a 2 just links together handwheel 1 and casing 3.Screw 4 is connected by screw thread
Connect and be screwed into positive stop strip, back-out screw 4 up to exposing beyond casing 3, but without departing from positive stop strip 2 when dismantling positive stop strip, then
Positive stop strip 2 is extracted using tool holder screw 4.
For this class formation, the defects of following main be present：
(1) because spacing strip material is relatively soft, nylon material is belonged to, toughness is preferably but intensity is weaker, so screw 4 exists
After being screwed into and back-outing repeatedly, 2 on positive stop strip on screw thread damage, screw can not be screwed into again.Cause to dismantle positive stop strip
It is difficult.
(2) positive stop strip 2 is when close to service life, it may occur that brittle fracture, once fracture, fracture nubbin can not take
Go out casing, so that handwheel 1 can not disassemble from casing 3, can not repair.
(3) utility model content：
The purpose of this utility model is to provide a kind of handwheel positive stop strip structure, and This structure increases positive stop strip screw thread is strong
Degree, once and ensure positive stop strip be broken, can easily be dismantled, preferably resolve skill present in known technology
Art problem.
The technical solution of the utility model：A kind of handwheel positive stop strip structure, including handwheel, casing and screw, the handwheel
Coordinated by gap and be assemblied in casing, it is characterised in that also including metal insert, positive stop strip b and steel wire rope, the metal
Inserts is fixed on positive stop strip b end, there is helicitic texture, the screw and metal insert screw thread on the outside of metal insert
Connection, the steel wire rope are integrally posted and fixed with positive stop strip b and are connected.
Positive stop strip b described above is integrally formed with metal insert and steel wire rope.
Operation principle of the present utility model：Metal insert is metalwork, ensure that the intensity of screw thread, steel wire rope it is embedding
Enter, ensure that positive stop strip b when brittle fracture occurs, breaking portion is remained attached to together by steel wire rope, is being dismantled
When can remove in the lump.
Superiority of the present utility model：Structure of the present utility model adds the screw strength of positive stop strip, and ensures once
Positive stop strip is broken, and can easily be dismantled.
(4) Figure of description：
Fig. 1 is the structural representation of handwheel positive stop strip structure in known technology.
Fig. 2 is Fig. 1 A-A sectional views.
Fig. 3 is a kind of structural representation of handwheel positive stop strip structure involved by the utility model.
Fig. 4 is Fig. 2 B-B sectional views.
Wherein, 1 is handwheel, and 2 be positive stop strip a, and 3 be casing, and 4 be screw, and 5 be positive stop strip b, and 6 be steel wire rope, and 7 be metal
Inserts.
(5) embodiment：
For invention, features and effects of the present utility model can be further appreciated that, following examples are hereby enumerated, and coordinate
Accompanying drawing describes in detail as follows：
Embodiment：A kind of handwheel positive stop strip structure, including handwheel 1, casing 3 and screw 4, the handwheel 1 are matched somebody with somebody by gap
Attach together and fit in casing 3, it is characterised in that also including metal insert 7, positive stop strip b 5 and steel wire rope 6, the metal insert
7 are fixed on positive stop strip b 5 end, and there are helicitic texture, the screw 4 and the screw thread of metal insert 7 in the outside of metal insert 7
Connection, the steel wire rope 6 are connected with overall post and fix of positive stop strip b 5.
Positive stop strip b 5 described above is integrally formed with metal insert 7 and steel wire rope 6.
Claims (2)
1. a kind of handwheel positive stop strip structure, including handwheel, casing and screw, the handwheel is coordinated by gap is assemblied in casing
