Abstract
The utility model discloses a locking linkage mechanism comprising a to-be-connected piece and a screw which are connected with each other. A gasket, sleeving the screw, and a nut, connected with the screw, are sequentially arranged above the to-be-connected piece. The locking linkage mechanism is characterized in that more than three countersunk through holes are formed in the gasket; threaded holes, in the aspect of number and position, correspond to the countersunk through holes and are arranged in the to-be-connected piece; the gasket and the to-be-connected piece are fastened through first screws penetrating the countersunk through holes to be connected with the threaded holes; more than three threaded through holes are formed in the nut and axially communicated, and second screws are connected in the threaded through holes. By the use of the locking linkage mechanism, fit clearances between the nut and the screw as well as between the to-be-connected piece and the screw are eliminated, thus during loading, a screw pair is effectively prevented from relative rotation with good anti-loose effect. The locking linkage mechanism has the advantages of simple structure, processing simplicity and mounting convenience.
Description
Technical field
The utility model relates to fastening piece, relates in particular to a kind of locking coupling mechanism.
Background technique
Being threaded generally can self-locking conditions satisfied, but under the effect of shock and vibration or varying load, the frictional force between screw pair may reduce or pop-off, after this phenomenon repeatedly repeats, will make to connect and gets loose.At present the normal locking mode adopting has pairs of anti-loose nut, spring washer locking etc., wherein spring washer is locking is that back cushion circle flattens and the elastic force that produces makes to screw between screw thread and compresses, this mode is simple in structure, easy to use, but because the elastic force of spring washer is uneven, cause its anti-loosing effect poor.Therefore be badly in need of a kind of spring-like packing ring locking simple in structure, easy to use, locking device that anti-loosing effect is good.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of simple in structure, easy to use, locking coupling mechanism that anti-loosing effect is good.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme: a kind of locking coupling mechanism, it comprises connected piece and the screw rod being coupled to each other, connected piece top is provided with the pad being placed on screw rod and the nut connecting with screw rod successively, pad is provided with three above countersunk head through holes, connected piece is provided with the tapped hole corresponding with the quantity of described countersunk head through hole and position, pad and connected piece are by through countersunk head through hole and the first screw fastened of connecting with tapped hole, nut is provided with three above screw-threaded counterbore that axially connect along it, in screw-threaded counterbore, be connected with the second screw.
The locking process of the locking coupling mechanism that the utility model provides is: pad passes through the first screw fastening on connected piece, then screw nut, finally the second screw threads is bonded to its lower end and pad leans, at this moment owing to having eliminated matching gap between nut and screw rod and the matching gap between connected piece and screw rod, therefore this locking coupling mechanism can effectively prevent that screw pair from relatively rotating when stand under load, and its anti-loosing effect is very good.Simultaneously the utility model also have advantages of simple in structure, be easy to processing, easy for installation.
As improvement of the present utility model, described pad is provided with the pit corresponding with the quantity of the second screw and position.The top of the second screw is stretched in pit, can further prevent from like this relatively rotating between nut and pad.
As improvement of the present utility model, on described the second screw, spring washer is installed.Spring washer is used for locking the second screw, prevents that the second screw from getting loose.
As improvement of the present utility model, on the sidewall of described nut, have some spliced eyes, spliced eye internal clearance is combined with handle.This structure is for manual installation nut, and because handle has increased the moment while screwing nut, so operator can mount and dismount nut easily, after installation or removal complete, handle are pulled down and are packed up, and avoid touching with miscellaneous equipment.
Accompanying drawing explanation
Fig. 1 is the utility model plan view.
Fig. 2 is A-A sectional view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
Referring to Fig. 1 and 2, the locking coupling mechanism that the utility model provides comprises connected piece 1 and the screw rod 2 being coupled to each other, connected piece 1 top is provided with the pad 4 being placed on screw rod 2 and the nut 3 connecting with screw rod 2 successively, pad 4 is provided with three above along its circumferential equally distributed countersunk head through hole 41, connected piece 1 is provided with the tapped hole 11 corresponding with the quantity of described countersunk head through hole 41 and position, pad 4 and connected piece 1 is by through countersunk head through hole 41 and the first screw 5 tightenings of connecting with tapped hole 11, nut 3 is provided with 12 screw-threaded counterbore 31 that axially connect along it, in described screw-threaded counterbore 31, be connected with the second screw 6, pad 4 is provided with the pit 42 corresponding with the quantity of the second screw 6 and position, on the second screw 6, spring washer 7 is installed, on the sidewall of nut 3, have some spliced eyes, spliced eye internal clearance is combined with handle 8.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
