Abstract
The utility model relates to the field of fasteners, in particular to a limit bolt. The technical scheme includes that the limit bolt comprises a bolt head and a screw, wherein a joint of the bolt head and the screw is provided with a flange plate, and the flange plate, the bolt head and the screw are arranged in an integrated mode. The outside of the bolt head is provided with a protective casing which is made of plastics in a covering mode, and the circumferential section of the protective casing is of a hexagon. The axial end of the protective casing is disposed in the mode of facing toward a convex arc protrusion which is in a direction far away from the flange plate. Compared with the prior art, the limit bolt has the advantages of being firm and reliable in locking and long in service life.
Description
Technical field
The utility model relates to technical field of fastening, definite says a kind of caging bolt.
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 head adopts metallic material to make, and uses parts and bolt head to slippage all can damage for a long time, and caging bolt is fixing unreliable simultaneously.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of bolt head to adopt plastics to make and flanged dish the caging bolt of long service life and reliable lock.
For achieving the above object; the utility model provides following technological scheme: a kind of caging bolt; include bolt head and screw rod; 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; 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.
The utility model further is set to: described bolt head is hexagon head, and corresponding protecting jacket is the hexagon cavity for the cavity of bolt head close-fitting.
Further be set to: described screw rod includes polished rod and is provided with externally threaded threaded stem, and polished rod is located between flange plate and the threaded stem, is arranged with rubber washer on the polished rod again.
Further be set to: described polished rod and flange plate joint are provided with the annular protrusion that arranges around one week of polished rod again, rubber washer is provided with circular groove towards a side inner hole wall of flange plate, and rubber washer cooperates with annular protrusion on the polished rod by circular groove and consists of the spacing of rubber washer.
By adopting technique scheme, the flange plate of caging bolt arranges the surface of contact that increases bolt-locking, so that being locked of caging bolt is reliable, 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 stereochemical structure view of the utility model specific embodiment;
Fig. 2 is the protecting jacket topology view of the utility model specific embodiment;
Fig. 3 is the rubber washer structural representation of the utility model specific embodiment.
Embodiment
Referring to accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, the disclosed a kind of caging bolt of the utility model 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 wherein flange plate 2, bolt head 1 and screw rod 3 are wholely set; 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); protecting jacket 10 axial end portions are for being towards arranging away from the cambered outwards circular arc projection of flange plate 2 sides; make like this caging bolt when spacing, 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, corresponding protecting jacket 10 is the hexagon cavity for the cavity 100 of bolt heads 1 close-fitting; 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 exist inconvenience or bolt head 1 defective poor with the connection reliability of protecting jacket 10 are set; So the utility model preferentially adopts the structure setting of this specific embodiment.
In the present embodiment, described screw rod 3 includes polished rod 30 and is provided with externally threaded threaded stem 31, and polished rod 30 is located between flange plate 2 and the threaded stem 31, is arranged with rubber washer 4 on the polished rod 30.Described polished rod 30 is provided with the annular protrusion 300 that arranges around 30 1 weeks of polished rod with flange plate 2 joints, rubber washer 4 is provided with circular groove 40 towards a side inner hole wall of flange plate 2, and rubber washer 4 cooperates the spacing of formation rubber washer 4 by circular groove 40 with annular protrusion 300 on the polished rod 30.Lower rubber washer 4 is set like this arranges, so that guarantee that having rubber washer 4 flange plate 2 is not easy to wear, and the location of rubber washer 4 is reliable.
