Abstract
The utility model discloses a cylindrical self-locking nut assembly which comprises a self-locking nut. A polygonal convex ring is arranged on the outer wall of the self-locking nut; a support frame is arranged outside the self-locking nut; a groove matched with the convex ring is formed in the support frame, and the bottom part of the groove is provided with a through hole; a pin hole is formed in the inner end surface of the support frame; and a pin is arranged in the pin hole. With the adoption of the technical scheme, the cylindrical self-locking nut assembly has the benefits that as the convex ring is matched with the groove in the support frame, the self-locking nut can be supported and prevented from rotating; and under the upper and lower limiting action of the pin, the self-locking nut can be effectively fixed. On an occasion where the assembly is more special, the defect of easy falling of the self-locking nut is overcome, so that the installation and the operation are more convenient, and the manpower and the material resources are further saved. In addition, the cylindrical self-locking nut assembly has the advantages of simple structure and lower manufacturing cost.
Description
Technical field
The utility model belongs to mechanical fasteners interconnection technique field, particularly a kind of tubular self-locking nut assembly parts.
Background technique
Self-locking nut is at screw mouth the closing in point to be set, and improves hardness through heat treatment, owing to can reach locking property, and have difficult loosening advantage with respect to plain nut, and in mechanical fasteners connection work, often use.But, using in the process of assembling at special occasions, existing self-locking nut drops easily, and inconvenient fitting operation can cause the waste of human and material resources.
Summary of the invention
The technical problem that the utility model will solve is: provide a kind of and using under the comparatively special occasion of assembling; Be convenient to fitting operation; Thereby save the tubular self-locking nut assembly parts of human and material resources; This assembly parts has advantage simple in structure, that fabricating cost is lower, to overcome the deficiency of existing technology.
The utility model is achieved in that and comprises self-locking nut 1; On the outer wall of self-locking nut 1, be provided with and constitute polygonal bulge loop 2; Outside self-locking nut 1, be provided with support 3, in support 3, have the groove 4 that agrees with bulge loop 2, and have through hole 5 in groove 4 bottoms; Interior edge face at support 3 is provided with pin hole, is provided with pin 6 in the pin hole.
In the above-mentioned tubular self-locking nut assembly parts, bulge loop 2 is quadrilateral or triangle.
In the aforesaid tubular self-locking nut assembly parts, support 3 overall exterior shape are tubular.
Owing to adopted technique scheme, with existing technology relatively, the interior groove of the bulge loop of the utility model and support agrees with, and self-locking nut has been played the function of support, anti-rotation, adds the position-limiting action up and down of pin, can effectively self-locking nut be fixed.Using under the comparatively special occasion of assembling, overcome the defective that self-locking nut drops easily, make fitting operation convenient, further saved human and material resources.In addition, the utlity model has advantage simple in structure, that fabricating cost is lower.

Being labeled as of accompanying drawing: 1-self-locking nut, 2-bulge loop, 3-support, 4-groove, 5-through hole, 6-pin.
Embodiment:
The embodiment of the utility model: the structure of the utility model is as shown in Figure 1; Comprise existing commercially available self-locking nut 1 (self-locking nut can be at screw mouth 1 to 9 closing in point to be set), on the outer wall of self-locking nut 1, make bulge loop 2 (as shown in Figure 3, bulge loop 2 can be made the all-in-one-piece structure with self-locking nut); Bulge loop 2 is made into polygonal; A support 3 (structure of support 3 such as Fig. 3 are to shown in Figure 5) is installed outside self-locking nut 1, and (shape according to the concrete polygon structure of bulge loop 2 is made groove 4 makes groove 4 to agree with bulge loop 2 in support 3, to offer groove 4; Thereby play the purpose that prevents that self-locking nut 1 from rotating); Offer through hole 5 in groove 4 bottoms, offer pin hole, pin 6 is installed in pin hole at the interior edge face of support 3.In order to simplify preparation process, can be with the structure fabrication quadrangularly or the triangle of bulge loop 2.In order to improve the attractive in appearance of the utility model, can support 3 overall exterior shape be made becomes tubular.
When the utility model uses: earlier self-locking nut 1 is placed in the support 3; In order to prevent that self-locking nut 1 from rotating, the 6 insertion pin holes of will pinning again limit self-locking nut 1 and are shifted up and down; At last bolt is passed the through hole 5 of self-locking nut 1 and groove 4 bottoms, can accomplish assembling.If equipped bad, desirable pin 6 is down ressembled.
Claims (3)
1. tubular self-locking nut assembly parts; Comprise self-locking nut (1), it is characterized in that: on the outer wall of self-locking nut (1), be provided with formation polygonal bulge loop (2), outside self-locking nut (1), be provided with support (3); In support (3), have the groove (4) that agrees with bulge loop (2); And offer through hole (5) in groove (4) bottom, and be provided with pin hole at the interior edge face of support (3), be provided with pin (6) in the pin hole.
