Description
Technical Field
The utility model relates to a fastener field, especially a locking combination formula bolt that moves.
Background
A fastener is a commonly used workpiece that is typically used to join two or more workpieces into a unitary structure. Bolts are the most common fasteners and are widely used in many fields because of their many advantages, such as self-locking, simple manufacture, mass production, low cost, and good interchangeability. The bolt consists of a nut and a screw which are connected with each other, wherein the screw is provided with an external thread, and the self-locking of the bolt in the axial direction is realized by the occlusion of the external thread on the screw and the internal thread in a threaded hole, so that the bolt can be fixedly connected with two different workpieces into a whole. However, the bolt is easy to rotate reversely in a vibration environment, and further the bolt is loosened and even falls off, so that great potential safety hazards are generated. There is therefore a need for a method or apparatus that addresses the above-mentioned problems.
SUMMERY OF THE UTILITY MODEL
The utility model relates to a solve above-mentioned technical problem, provide a simple structure, design benefit, rationally distributed, can't take place the reversal after connecting to realize the combination formula bolt of locking not hard up effect.
The technical solution of the utility model is that: the utility model provides a locking combination formula bolt that moves, includes bolt body and the gasket rather than matching, its characterized in that: the bolt body consists of a screw rod part 1 and a head part 2 which are integrated, a circle of plane ratchets 3 are arranged on the bottom end surface of the head part 2,
the gasket is annular, three elastic parts 4 which are uniformly distributed in the circumferential direction are arranged on the gasket, a first tooth-shaped part 5 which is matched with the plane ratchet 3 is arranged at the higher end of each elastic part 4, one end of each first tooth-shaped part 5 is connected with the gasket through an elastic connecting part 6, a second tooth-shaped part 7 is arranged at the lower end of each elastic part 4, and meanwhile the second tooth-shaped parts 7 are not connected with the gasket.
Compared with the prior art, the utility model, have following advantage:
the anti-loosening combined bolt with the essential structure is simple in structure, ingenious in design and reasonable in layout, and aims at the problem that a bolt with the traditional structure is easy to loosen under the vibration effect, a special structure is designed, a circle of plane ratchets are creatively arranged on the bottom surface of the end part of the bolt, an annular gasket with a special elastic part structure is arranged for the bolt, when the bolt is screwed, the normal movement of the bolt cannot be blocked by the plane ratchets, meanwhile, after the bolt is screwed, the elastic annular gasket can be tightly pressed, one end (a first tooth-shaped part) of an elastic part arranged on the annular gasket can be contacted with the plane ratchets, and the other end (a second tooth-shaped part) of the elastic part can be clamped on the surface of a fastened piece, so that the bolt is locked, the bolt is prevented from reversing, and the aim of preventing the bolt from loosening is fulfilled. The combined bolt has the advantages of simple manufacturing process and low manufacturing cost, so the combined bolt has various advantages, is particularly suitable for popularization and application in the field, and has very wide market prospect.
Drawings
Fig. 1 is a schematic structural diagram (working state one) of the embodiment of the present invention.
Fig. 2 is a schematic structural diagram (working state two) of the embodiment of the present invention.
Fig. 3 is a schematic structural view of a gasket portion according to an embodiment of the present invention.
Detailed Description
The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1 to 3: a locking combined bolt comprises a bolt body and a gasket matched with the bolt body, wherein the bolt body consists of a screw rod part 1 and an end head part 2 which are integrated, a circle of plane ratchets 3 are arranged on the bottom end surface of the end head part 2,
the gasket is annular, three elastic parts 4 which are uniformly distributed in the circumferential direction are arranged on the gasket, a first tooth-shaped part 5 which is matched with the plane ratchet 3 is arranged at the higher end of each elastic part 4, one end of each first tooth-shaped part 5 is connected with the gasket through an elastic connecting part 6, a second tooth-shaped part 7 is arranged at the lower end of each elastic part 4, and meanwhile the second tooth-shaped parts 7 are not connected with the gasket.
The utility model discloses locking combination formula bolt's that moves working process as follows: sleeving an annular gasket on a bolt body, in particular to the screw part 1, screwing the bolt body into a threaded hole formed in a workpiece 8 to be fastened in the state that a first tooth-shaped part 5 faces to the plane ratchet 3, enabling an end part 2 to gradually approach the gasket and finally contact the gasket along with the rotation of the bolt body, extruding and deforming all elastic parts 4 on the gasket under the action of the end part 2, enabling the first tooth-shaped part 5 at one end of the elastic part 4 to contact the plane ratchet 3 and enabling a second tooth-shaped part 7 at the other end to contact the surface of the workpiece 8 to be fastened,
because the plane ratchet 3 is arranged on the bottom end face of the head part 2, when the bolt body rotates forwards, the first tooth-shaped part 5 does not obstruct the head part 2, but after the bolt body is completely screwed, the first tooth-shaped part 5 is in contact with the plane ratchet 3, the head part 2 can be prevented from rotating backwards, meanwhile, after the bolt body is screwed, under the extrusion effect of the head part 2, the bottom edge of the second tooth-shaped part 7 can be clamped into the surface of the fastened workpiece 8, namely the elastic part 4 is clamped between the fastened workpiece 8 and the plane ratchet 3 in the state, if the spiral body is required to rotate backwards relative to the fastened workpiece 8, the surface of the fastened workpiece 8 needs to be damaged, and the effect of preventing the bolt from loosening is achieved.
