Abstract
The utility model discloses a patch self-locking bolt. The patch self-locking bolt comprises a bolt (1), wherein one to four patch grooves (3) are formed on a threaded section (2) of the bolt (1); and patches (4) are pasted in the patch grooves (3). As the patch grooves are only milled on the threaded section of the bolt, and the nylon patches are pasted in the patch grooves, the nylon patches can be tightly fastened with threads of a nut to generate the locking force under the plastic squeezing action of nylon, thereby achieving the self-locking function and simple manufacture. The patch self-locking bolt has the characteristics of reliable self-locking performance, excellent strength, light weight, undemanding heat treatment, easy manufacture and low manufacturing cost.
Description
Technical field
The utility model relates to a kind of fastening piece, particularly relates to a kind of paster self-locking screw.
Background technique
Common bolt does not generally all have auto-lock function, is used in general occasion and can satisfies usage requirement substantially.But be used in the bigger occasion of some vibrations, because vibration can cause bolt looseness.So, must use to prevent the self-locking screw that becomes flexible in some special occasions.Self-locking screw in the market is a lot, and structure also has nothing in common with each other.Some self-locking screw using effect is undesirable, also has some to make trouble, cost of production height; Also some intensity is not so good.
The model utility content
The purpose of this utility model is to provide a kind of paster self-locking screw, and self-locking is reliable, and intensity is good, and is in light weight, to heat treated less demanding, makes the characteristics that cost of production is low easily.
The technical solution of the utility model: a kind of paster self-locking screw, comprise bolt, have 1～4 paster groove on the thread section of bolt, post paster in the paster groove.
In the above-mentioned paster self-locking screw, have 2 paster grooves on the thread section of described bolt, post paster in the paster groove.
In the aforementioned patch self-locking screw, described paster groove is a rectangle groove, and the length direction direct-axis of paster groove is to setting.
In the aforementioned patch self-locking screw, the shape of described paster is corresponding with the shape of paster groove.
In the aforementioned patch self-locking screw, the thickness of described paster is not more than the vertical height of paster groove bottom to the screw thread crown.
In the aforementioned patch self-locking screw, described paster is made with nylon material.
Compared with prior art, the utility model just mills the paster groove at the thread section of bolt, and pastes the nylon paster in the paster groove, utilizes the plasticity squeezing action of nylon, and the nylon paster is killed to cooperate by nut thread and produced coupling mechanism force; Reach the function of self-locking, make simple.It is reliable to the utlity model has self-locking, and intensity is good, and is in light weight, to heat treated less demanding, makes the characteristics that cost of production is low easily.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the connection diagram of the utility model and nut;
Fig. 3 is the schematic representation that connects two-layer sheet material with the utility model.
Being labeled as in the accompanying drawing: 1-bolt, 2-thread section, 3-paster groove, 4-paster, 5-nut, 6-upper junction plate, 7-lower connecting plate.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment.A kind of paster self-locking screw, its three-dimensional structure diagram comprise bolt 1 as shown in Figure 1, and the thread section 2 of bolt 1 is provided with 1～4 paster groove 3, preferably are symmetrical arranged 2 paster grooves 3.Paster groove 3 is a rectangle groove, and the length direction direct-axis of paster groove 3 is to setting.Post paster 4 in the paster groove 3.Paster 4 usefulness nylon materials are made.The shape of paster 4 is corresponding with the shape of paster groove 3.The thickness of paster 4 is not more than the vertical height of paster groove 3 bottom surfaces to the screw thread crown, and after paster 4 posted, paster preferably was not higher than crown.
