Abstract
The utility model relates to the technical field of fasteners, in particular to a limiting bolt stable in locking. The technical scheme includes that the limiting bolt stable in the locking comprises a bolt head and a screw, wherein an outer thread is arranged on the screw, and a flange plate is arranged at the connecting position of the bolt head and the screw. The flange plate, the bolt head and the screw are integrally arranged. The flange plate is a concave arc-shaped circular plate which faces backwards the direction of the screw. A plurality of lugs are evenly distributed on the edge of the concave arc-shaped circular plate. Compared with the prior art, the limiting bolt stable in the locking has the advantages of being easy and convenient to operate, and reliable and firm in the locking and fixing.
Description
Technical field
The utility model relates to technical field of fastening, is specifically related to a kind of caging bolt of reliable lock.
Background technique
Nowadays, bolt has been applied to various fields as most basic connector element, by bolt head and a screw rod class fastening piece dimerous, is widely used in every field.Caging bolt is a kind of as fastening piece, is used for fixed component and other parts are carried out position-limiting action; Caging bolt then is to limit the relatively parts of slippage by head, existing caging bolt has plain bolt, bolt fixedly time locking is unreliable, particularly when a few thing, have on the machine of vibration, caging bolt occurs loosening easily in use for some time, it is firmly reliable for it is locked, usually put open washer at bolt and add the screw rod of king-bolt and the frictional force between the mounting hole matching thread, and then prevent bolt looseness, although this method can well play the effect of nut anti-looseness, but also there is a deficiency, that is exactly before construction bolt, to put open washer at bolt first, use so just cumbersome.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of and need not to add open washer and just can realize the caging bolt that reliably is locked.
For achieving the above object, the utility model provides following technological scheme: a kind of caging bolt of reliable lock, include bolt head and screw rod, screw rod is provided with outside thread, it is characterized in that: described bolt head and screw rod joint are provided with flange plate, flange plate, bolt head and screw rod are wholely set, and flange plate is that the curved circular plate edge is evenly equipped with several lugs towards the arc disk that deviates from screw rod direction depression.
The utility model further is set to: the protecting jacket that plastics are made is established in described bolt head outsourcing, and the protecting jacket circumferential cross-section is hexagon, and the protecting jacket axial end portion is for being towards arranging away from the cambered outwards circular arc projection in flange plate side.
Further be set to: described bolt head is hexagon head again, and corresponding protecting jacket is the hexagon cavity for the cavity of bolt head close-fitting.
Further be set to: the cavity bottom of described protecting jacket is the plane, and the end end face of respective bolt head is plane layout again.
By adopting technique scheme, compared with prior art, the utility model nut has the following advantages: to rely in use open washer to carry out locking different from common bolt, the bolt head of bolt is provided with an arc disk, the edge of arc disk is evenly equipped with a plurality of lugs, after screwing bolt, offset between arc disk on the bolt and the installation body end face, resiliently deformable can occur in the arc disk, produce the elastic deformation force, rely on the elastic deformation force of arc disk to replace the elastic force of spring washer to prevent bolt looseness, the lug on the curved circular plate edge can be pressed on the component that are locked firmly simultaneously, can better prevent bolt looseness; The protecting jacket that bolt head outsourcing plastics are made is effectively protected limited parts and bolt head.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the caging bolt three-dimensional view of the utility model specific embodiment reliable lock;
Fig. 2 is the sectional view that the caging bolt of the utility model specific embodiment reliable lock dissects vertically.
Embodiment
Referring to accompanying drawing 1, accompanying drawing 2, the utility model discloses a kind of caging bolt of reliable lock, includes bolt head 1, flange plate 2 and screw rod 3, and flange plate 2 is located at bolt head 1 and screw rod 3 joints, and flange plate 2, bolt head 1 and screw rod 3 are wholely set; Wherein flange plate 2 is that the curved circular plate edge is evenly equipped with several lugs 20 towards the arc disk that deviates from screw rod 3 directions depression.Under the said structure, to rely in use open washer to carry out locking different from common bolt, the bolt head 1 of the utility model bolt is provided with an arc disk, the edge of arc disk is evenly equipped with a plurality of lugs 20, after screwing bolt, offset between arc disk on the bolt and the installation body end face, resiliently deformable can occur in the arc disk, produce the elastic deformation force, rely on the elastic deformation force of arc disk to replace the elastic force of spring washer to prevent bolt looseness, lug on the curved circular plate edge can be pressed on the component that are locked firmly simultaneously, can prevent better that caging bolt is loosening.
Be protection bolt head 1; the protecting jacket 10 that plastics are made is established in described bolt head 1 outsourcing; be that protecting jacket 10 is provided with cavity 100; bolt head 1 close-fitting is integral in the cavity 100 of protecting jacket 10; protecting jacket 10 circumferential cross-section are hexagon (head that is caging bolt confession tool operation is hexagon head), and protecting jacket 10 axial end portions make caging bolt when spacing for being towards arranging away from the cambered outwards circular arc projection of flange plate 2 sides like this; the confined planes reasonable stress, it is little to wear and tear.
For ease of being connected between bolt head 1 and the protecting jacket 10 reliable, described bolt head 1 is hexagon head, the cavity 100 for bolt head 1 close-fitting on the corresponding protecting jacket 10 is the hexagon cavity, cavity 100 bottoms are plane layout, bolt head 1 end end face is plane layout; Certainly bolt head 1 can be circular or other polygonal, but adopt circle that protecting jacket 10 and bolt head 1 are slided, occur breaking away from, adopt other polygonal to have the poor defective of connection reliability that inconvenience or bolt head and protecting jacket are set; So the utility model preferentially adopts the structure setting of this specific embodiment.
