Abstract
The utility model discloses a locking screw bolt combining element, which comprises a screw bolt (1), wherein at least one key slot (3) is arranged on a threaded section (2) of the screw bolt (1), and a key block (4) is arranged in the key slot (3). During the screw bolt processing by the locking screw bolt combining element, at least one key slot 3 is milled on the threaded section (2) of the screw bolt 1, and the key block 3 is inserted into the key slot 3. When the screw bolt 1 is screwed into a screw nut 5, the key block 4 is subjected to extrusion deformation through threaded teeth arranged on the screw nut 5, screw threads tightly matched with the screw nut 5 are extruded on the key block 4 so that the screw threads of the screw nut 5 are tightly engaged and matched with the screw threads of the key block 4 for generating locking force, and a self locking function is realized. The locking screw bolt combining element has the characteristics that the self locking is reliable, the intensity is good, the weight is light, the heat treatment requirement is not high, the manufacture is easy, and the production cost is low.
Description
Technical field
the utility model relates to a kind of lock bolt assembly parts, belongs to the self-locking screw technical field.
Background technique
common bolt does not generally all have auto-lock function, is used in general occasion and can satisfies usage requirement basically.But be used in the bigger occasion of some vibrations, because vibration can cause bolt looseness.So, must use a kind of shockproof lock bolt in some special occasions.Lock bolt in the market is a lot, and structure also has nothing in common with each other.Some lock bolt using effect is undesirable, also has some to make trouble, and cost of production is high; Also some intensity is not so good.
Summary of the invention
The purpose of
the utility model is, a kind of lock bolt assembly parts is provided.Reliable lock, intensity is good, and is in light weight, to heat treated less demanding, makes the characteristics that cost of production is low easily.
The technological scheme of the utility model
a kind of lock bolt assembly parts comprises bolt, and the thread section of bolt is provided with at least one keyway, is provided with the key piece in the keyway.
In
aforesaid lock bolt assembly parts, the length direction direct-axis of said keyway is provided with.
In
aforesaid lock bolt assembly parts, the bottom shape of said keyway is arc, trapezoidal or stepped shape.
In
aforesaid lock bolt assembly parts, the bottom shape of said key piece is corresponding with the bottom shape of keyway.
In
aforesaid lock bolt assembly parts, said key piece is nylon or the hardness Steel Work less than bolt.
compared with prior art; The utility model only need mill out at least one keyway at the thread section of bolt; And in keyway, insert the key piece, when bolt is screwed in nut, utilize the thread on the nut that the key piece is carried out extrusion-deformation; On the key piece, squeeze out and the friction tight screw thread of nut, make the screw thread of nut cooperate the generation coupling mechanism force with the thread biting locking of key piece; Reach the function of self-locking, 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.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the utility model and the schematic representation that is connected of nut.
Be labeled as among
figure: 1-bolt, 2-thread section, 3-keyway, 4-key piece, 5-nut.
Embodiment
are further described the utility model below in conjunction with accompanying drawing and embodiment, but not as the foundation to the utility model restriction.
embodiment.
a kind of lock bolt assembly parts, as shown in Figure 1.A kind of lock bolt assembly parts comprises bolt 1, and the thread section 2 of bolt 1 is provided with at least one keyway 3, is provided with key piece 4 in the keyway 3.The length direction direct-axis of keyway 3 is provided with.The bottom shape of keyway 3 is arc, trapezoidal or stepped shape.The bottom shape of key piece 4 is corresponding with the bottom shape of keyway 3.Key piece 4 is nylon or the hardness Steel Work less than bolt 1.
The locking principle and the method for using of the utility model
are as shown in Figure 2, add man-hour carrying out bolt, only need mill out at least one keyway 3 at the thread section 2 of bolt 1, and keyway 3 in insertion key piece 4.When bolt 1 is screwed in nut 5, utilize the thread on the nut 5 that key piece 4 is carried out extrusion-deformation, on key piece 4, squeeze out and nut 5 friction tight screw threads, make the screw thread of nut 5 cooperate the generation coupling mechanism force with the thread biting locking of key piece 4; Reach the function of self-locking, 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.
