Abstract
The utility model provides bolt anticreep locking mechanism, comprises the first bolt, the first workpiece, second workpiece, clamping bolt; The lower end surface of the first bolt head is provided with the bolt extension dish that cross-section area is greater than its cross-section area; Bolt extension dish has multiple through hole matched with clamping bolt; First workpiece is screwed together by the first bolt and second workpiece, and clamping bolt is screwed on bolt extension dish by the through hole on bolt extension dish, and with the first workpiece close contact.Undertaken fastening by multiple stove bolt, reach lock bolt itself, reduce the object in the gap of internal and external threads, this bolt-locking structure have employed simple mounting type, greatly reduces installation manpower, and it is simple to have structure, the features such as convenient disassembly.
Description
Technical field
The utility model relates to bolt anticreep locking mechanism.
Background technique
Due to the restriction of state-of-the-art, processing technology, internal thread in bolt arrangement and there is certain gap between outside thread, the bolt of workpiece of being spirally connected easily produces loosening, and even comes off, this phenomenon comparatively large, that screw thread the is longer bolt of pitch embody with it particularly evident.In this case, locking mechanism is mechanically generally adopted to solve problem.But mostly bolt-locking structure all also exists some shortcomings, as hydraulic locking nut, complex structure volume is comparatively large, conventional springs gasket construction, at large diameter bolt application aspect manpower difficult and, bolt adds stop pin pin structure, and dismounting trouble can not be locked completely.
Summary of the invention
Problem to be solved in the utility model is to provide Novel bolt locking mechanism, by the complete lock bolt of easy structure and nut, and installs very easy.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: bolt anticreep locking mechanism, comprises the first bolt, the first workpiece, second workpiece, clamping bolt;
The lower end surface of the first bolt head is provided with the bolt extension dish that cross-section area is greater than its cross-section area;
Bolt extension dish has multiple through hole matched with clamping bolt;
First workpiece is screwed together by the first bolt and second workpiece, and clamping bolt is screwed on bolt extension dish by the through hole on bolt extension dish, and with the first workpiece close contact.
Further, bolt extension dish is circular, and with the first bolt head shaft axis conllinear.
Further, bolt extension dish along the circumferential direction has multiple through hole matched with clamping bolt.
Bolt anticreep locking mechanism, comprises the second bolt, nut, the first workpiece, second workpiece, clamping bolt;
Second bolts and nuts match;
The upper-end surface of nut is provided with the nut extension dish that cross-section area is greater than its cross-section area;
Nut extension dish has a through hole matched with the screw rod of nut and the second bolt.
Nut extension dish has multiple through hole matched with clamping bolt;
First workpiece is screwed together by the second screw bolt and nut and second workpiece, and clamping bolt is screwed on nut extension dish by the through hole that nut extension dish matches with it, and with second workpiece close contact.
Further, nut extension dish is circular, and with nut shaft axis conllinear.
Further, nut extension dish along the circumferential direction has multiple through hole matched with clamping bolt.
The advantage that the utility model has and good effect are: undertaken fastening by multiple stove bolt, reach lock bolt itself, reduce the object in the gap of internal and external threads.This bolt-locking structure have employed simple mounting type, greatly reduces installation manpower, and it is simple to have structure, the features such as convenient disassembly.

Embodiment
Embodiment one
As shown in Figure 1, bolt anticreep locking mechanism, comprises the first bolt 1, first workpiece 4, second workpiece 5, clamping bolt 3.
The lower end surface of the first bolt 1 head is provided with the bolt extension dish 2 that cross-section area is greater than its cross-section area;
Bolt extension dish 2 has multiple through hole matched with clamping bolt 3.
As shown in Figure 1, first workpiece 4 is screwed together with second workpiece 5 by the first bolt 1, clamping bolt 3 is screwed on bolt extension dish 2 by the through hole on bolt extension dish 2, and offset with the first workpiece 4, make to produce frictional force between clamping bolt 3 and first component 4, prevent the first bolt 1 generation from loosening and even come off.
The present embodiment also can do following improvement:
As shown in Figure 2, bolt extension dish 2 is circular, and with the first bolt 1 head shaft axis conllinear; Circular bolt extension dish 2 along the circumferential direction has multiple through hole matched with clamping bolt 3.Be screwed in by this through hole the frictional force produced between clamping bolt 3 on bolt extension dish 2 and the first workpiece 4 to be evenly distributed, the external force that can alleviate from all directions affects.
Embodiment two
As shown in Figure 3, bolt anticreep locking mechanism, comprises the second bolt 6, nut 7, first workpiece 4, second workpiece 5, clamping bolt 3.
Second bolt 6 matches with nut 7.
The upper-end surface of nut 7 is provided with the nut extension dish 8 that cross-section area is greater than its cross-section area.
Nut extension dish 8 has a through hole matched with the screw rod of nut 7 and the second bolt 6.
Nut extension dish 8 has multiple through hole matched with clamping bolt 3.
First workpiece 4 is screwed together with second workpiece 5 by the second bolt 6 and nut 7, clamping bolt 3 is screwed on nut extension dish 8 by the through hole that nut extension dish 8 matches with it, and offset with second workpiece 5, make to produce frictional force between clamping bolt 3 and second workpiece 5, prevent the second bolt 6 and nut 7 from occurring looseningly even to come off.
The present embodiment also can do following improvement:
As shown in Figure 4, nut extension dish 8 is circular, and with nut 7 head shaft axis conllinear; Circular nut extension dish 8 along the circumferential direction has multiple through hole matched with clamping bolt 3.Be screwed in by this through hole the frictional force produced between clamping bolt 3 on nut extension dish 8 and second workpiece 5 to be evenly distributed, the external force that can alleviate from all directions affects.
