CN-224223952-U - Folding knife shaft lock rod structure

Abstract

The utility model relates to the technical field of folding knife lock rods, in particular to a folding knife shaft lock rod structure, which aims to solve the problems that when the existing folding knife rotates to retract a knife, the contact area is large, the resistance of the retracting operation is increased, and the use experience of a user is reduced; the utility model discloses a set up the arc board at the locking lever surface, when rotatory receipts sword, cutting edge backbone surface contacts with arc board surface convex face, compare in traditional design, greatly reduced area of contact between the two, area of contact reduces, frictional force is showing the reduction with it also, and then reduced the resistance of receipts sword operation for receipts sword process is more smooth and easy, simultaneously, the frictional force that reduces can also reduce the noise because of the friction produces, so far through arc board and cutting edge backbone contact of arcuation, can reduce the problem of frictional force and noise, finally promoted the effect that the user used to experience.

Description

Folding knife shaft lock rod structure Technical Field The utility model relates to the technical field of folding knife lock rods, in particular to a folding knife shaft lock rod structure. Background The utility model provides a folding knife, is a portable cutter of folding incorporation handle of a knife, and folding knife can be used to cutting rope, open can in daily, also can be used to at home tear open express delivery, prune bouquet etc. however, in the shaft lock type folding knife on the market at present, when opening and closing the blade, the locking lever can be contacted with blade gyration backbone, the contact piece is the line contact, because the influence of machining precision, hardly guarantees that whole line is fully contacted, this just causes the cutter head to rock after the opening easily, the blade eccentric, the in-process frictional force of switch sword is big, smooth and easy degree is not good, the noise is big problem, also hardly the tool setting in the equipment process, equipment difficulty and consumer experience are very poor, has led to reducing user experience. Disclosure of utility model The utility model aims to provide a folding knife shaft lock rod structure which adopts the device to work, thereby solving the problems that the contact area is large, the resistance of the folding knife operation is increased and the use experience of a user is reduced when the existing folding knife rotates to fold the knife. The folding knife shaft lock rod structure comprises a lower clamp handle arranged below the upper clamp handle, a blade body is movably arranged between the upper clamp handle and the lower clamp handle, one end of the blade body is provided with a blade spine, an upper clamping plate is fixedly arranged on the lower surface of the upper clamp handle, a rod groove is formed in the upper surface of the upper clamping plate in a penetrating way, a bottom groove is formed in the upper surface of the upper clamp handle, a hole is formed in the surface of the upper clamp handle and communicated with the rod groove, one end of the hole penetrates through the lower clamp handle, a lock rod is movably arranged in the rod groove, and a lower clamping plate is fixedly arranged on the upper surface of the lower clamp handle; The locking lever is the sectional type setting, fixed mounting has the roof on the locking lever, locking lever surface fixed mounting has the limiting disc, locking lever surface fixed mounting has the arc board, the arc board is in locking lever middle-end portion, the limiting disc is located the arc board top, the arc board surface is laminated with cutting edge backbone surface mutually, limiting disc lower surface is laminated with the upper surface mutually. Further, a groove is formed in one end of the blade body, and the groove is matched with the arc plate. Further, an omega spring is arranged between the limiting disc and the top plate, and one end of the omega spring is provided with a sliding rod. Further, a disc hole is formed in the upper surface of the upper clamping plate, and the disc hole is matched with the limiting disc. Further, the surface of the upper clamping plate is provided with adjusting grooves, the adjusting grooves are provided with a plurality of groups of adjusting holes, and the adjusting grooves and the adjusting holes are both in sliding connection with the sliding rod. Further, the wire clamp is fixedly arranged on the outer surface of the lower clamp handle, the wire clamp is fixedly arranged on the lower clamp handle through bolts, a decorative sheet is movably arranged in the wire clamp, semicircular holes are formed in two sides of the decorative sheet, and the semicircular holes are matched with the surface of the wire clamp. Compared with the prior art, the utility model has the following beneficial effects: according to the folding knife shaft lock rod structure, when the folding knife is required to be folded, the lock rod is moved in the direction away from the knife edge body, the knife edge spine of the folding knife shaft lock rod structure rotates to contact the arc plate of the lock rod, the arc plate is arc-shaped, the contact area between the arc plate and the surface of the knife edge spine is greatly reduced, the lock rod is contacted with the groove after the folding knife is completed by the knife edge body, the omega spring releases the elastic band lock rod to enter the groove, the knife edge body after folding knife is firmly fixed between the upper clamping plate and the lower clamping plate, the arc plate is contacted with the knife edge spine, the friction force and the noise can be reduced, and the use experience effect of a user is finally improved.
