Abstract
The utility model discloses a nut for a crane. The nut comprises a nut body, wherein a convex edge which protrudes out of the nut body is formed on the inner side of the nut body; the convex edge is a thin-walled circular ring which is formed on the inner wall side of the nut body; the inner diameter of the convex edge is not smaller than that of the inner wall of the nut body; and a thread is formed on the inner wall of the convex edge. The convex edge can be screwed in an inner wall of equipment to be fixed which is matched with the nut so as to form a clamping position of the convex edge; because the contact area is enlarged, the friction force is increased, and the nut is difficult to loosen; and meanwhile, the thread formed on the inner wall of the convex edge has the anti-looseness function of the thread, the dual anti-looseness effects of the clamping position of the convex edge and the thread are achieved, the nut can be effectively prevented from loosening or dropping, and normal operation of the equipment is guaranteed; and therefore, the potential safety hazard is reduced.
Description
Technical field
The utility model relates to a kind of nut, particularly a kind of 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 nut that is used for hoist that can effectively prevent the stopping pine is provided.
The utility model adopts following technological scheme:
A kind of nut that is used for hoist; Include nut body, said nut body inboard be formed with one protrude from nut body the convex edge, this convex edge is the thin wall circular that is formed at said nut body inwall side; This convex edge internal diameter is not less than nut body inwall internal diameter, and this convex edge inwall also is provided with screw thread.
Offer the spanner screens of one group of groove-like that evenly is provided with on all edges of said nut body.
Said nut body inwall is provided with screw thread.
Can know that by above-mentioned description compared with prior art, the beneficial effect of the utility model is: can constitute the convex edge screens through the convex edge being screwed in the fixed equipment inwall of treating that matches with this nut to the utility model; And owing to increased area of contact, frictional force increases, and more is difficult for moving back pine; Simultaneously; The screw thread of being located at this convex edge inwall also has the locking thread effect, have the convex edge screens locking with the dual locking effect of locking thread, can prevent effectively that 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 figure 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. convex edge, 4. 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 nut that is used for hoist of the utility model includes nut body 1, and this nut body 1 inwall is provided with screw thread 2; Said nut body 1 inboard be formed with one protrude from nut body 1 convex edge 3; This convex edge 3 is for being formed at the thin wall circular of said nut body 1 inwall side, and these convex edge 3 diameters are not less than nut body 1 inner diameter, and these convex edge 3 inwalls also are provided with screw thread 2.Offer the spanner screens 4 of four groove-like that evenly are provided with on said nut body 1 all edges.
With reference to Fig. 1, Fig. 2 and Fig. 3, when the utility model uses, can constitute the convex edge screens through convex edge 3 being screwed in the fixed equipment inwall of treating that matches with this nut; And owing to increased area of contact, frictional force increases, and more is difficult for moving back pine; Simultaneously, the screw thread 2 of being located at these convex edge 3 inwalls also has the locking thread effect, the utlity model has the locking and dual locking effect of locking thread of convex edge screens; 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.
Claims (3)
1. nut that is used for hoist; Include nut body; It is characterized in that: said nut body inboard be formed with one protrude from nut body the convex edge; This convex edge is the thin wall circular that is formed at said nut body inwall side, and this convex edge internal diameter is not less than nut body inwall internal diameter, and this convex edge inwall also is provided with screw thread.
2. a kind of nut that is used for hoist as claimed in claim 1 is characterized in that: the spanner screens that offers one group of groove-like that evenly is provided with on all edges of said nut body.
