Abstract
A locknut for a crane comprises a nut body, wherein a thread is arranged on the inner wall of the nut body, a fan-shaped screw-threaded coupling groove along the outer wall of the circumference is arranged on the nut body and penetrates through the inner wall of the nut body, the fan-shaped screw-threaded coupling groove cuts the nut body in the corresponding position into two nut pieces, space which is capable of clamping the thread is formed between the two nut pieces, and a group of threaded holes which penetrate through the two nut pieces are disposed on the two nut pieces. When the locknut for the crane is used, a screw is screwed into the threaded holes after the nut body is fastened, the two nut pieces are compressed and locked, the two nut pieces are capable of tightly compressing the thread which is matched with the thread on the inner wall of the nut, so that the thread is fully compressed and elastically deformed. Therefore, loosing or dropping for the nut is effectively prevented, normal operation of a device is ensured, and safety hazard is reduced.
Description
Technical field
The utility model relates to a kind of nut, particularly a kind of lock nut that is used for hoist.
Background technique
At present, the existing nut that is used for the crane facility main shaft includes a nut body, and this nut body inwall is provided with screw thread; Week is along being provided with a plurality of spanner screens; When the nut of this kind structure uses, owing to only rely on the screw thread of nut body inwall to fix, be easy to move back pine even come off; Thereby the equipment that possibly influence normally moves, and constitutes potential safety hazard.
The model utility content
The main purpose of the utility model is the shortcoming that overcomes existing technology, and a kind of lock nut that is used for hoist that can be effectively locking is provided.
The utility model adopts following technological scheme:
A kind of lock nut that is used for hoist; Include nut body; This nut body inwall is provided with screw thread, offers one on the said nut body and runs through the fan ring screw locking slot of nut body inwall along the periphery wall, and this screw-threaded coupling groove is cut to two nut sheets with the nut body branch of its corresponding position; Be formed with the space that can insert and put screw thread between the two nut sheets, also offer one group of screw hole on the two nut sheets through two nut sheets.
Said nut body week is along offering one group of groove-like spanner screens that evenly is provided with.
Said nut body adopts elastic material to process.
Can know that by above-mentioned description compared with prior art, the beneficial effect of the utility model is: during use to the utility model; After nut body screwed, through with screw DRIVE SCREWS hole, can be with two nut sheets compression locking; Two nut sheets can will be pressed in therebetween with this nut inner wall threads engaged screw thread, and make the threaded integral compression produce elastic strain, can prevent effectively that therefore nut from moving back pine or come off; Assurance equipment normally moves, thereby reduces potential safety hazard.
Description of drawings
Fig. 1 is the three-dimensional structure diagram of the utility model embodiment;
Fig. 2 is the plan structure perspective view of the utility model embodiment;
Fig. 3 is the side-looking structure perspective view of the utility model embodiment.
Among the figure: 1. nut body, 2. screw thread, 3. screw-threaded coupling groove, 4. nut sheet, 5. screw hole, 6. spanner screens.
Embodiment
Below the utility model is done further to describe through embodiment.
With reference to Fig. 1, Fig. 2 and Fig. 3; A kind of lock nut that is used for hoist of the utility model; Include nut body 1; This nut body 1 inwall is provided with screw thread 2, offers one on the said nut body 1 and runs through the fan ring screw locking slot 3 of nut body 1 inwall along the periphery wall, and this screw-threaded coupling groove 3 was cut to two nut sheets 4 in 1 minute with the nut body of its corresponding position; Be formed with the space that can insert and put screw thread between the two nut sheets 4, also offer two screw holes 5 on the two nut sheets 4 through two nut sheets 4.Said 1 week of nut body is along offering four groove-like spanner screens 6 that evenly are provided with.Said nut body 1 adopts elastic material to process.
With reference to Fig. 1, Fig. 2 and Fig. 3, when the utility model uses, after nut body 1 screwed; Through with screw DRIVE SCREWS hole 5, can 4 compressions of two nut sheets be locked, two nut sheets 4 get final product the screw thread that will match with this nut body 1 inner thread 2 and are pressed in therebetween; And make the threaded integral compression produce elastic strain; Therefore can prevent effectively that nut from moving back pine or come off, assurance equipment normally moves, thereby reduces potential safety hazard.
An above-mentioned embodiment that is merely the utility model, but the design concept of the utility model is not limited thereto allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
