Description

TECHNICAL FIELD

[0001] The utility model relates to the fastener field, more specifically, it relates to a kind of anti-skid nut. BACKGROUND

[0002] Nut, also known as nut, is a fastening part used with bolt or screw, which realizes the connection and fixation of mechanical equipment through internal thread. Its material includes carbon steel, stainless steel, copper alloy, etc., and it is widely used in various mechanical manufacturing. According to different specifications and standards, nut can be divided into hexagonal nut, locking nut, flange nut and other types. The utility model is aimed at commonly used hexagonal nut.

[0003] In the field of mechanical assembly and maintenance, hexagonal nut is widely used due to its symmetrical structure and convenient wrench operation. The corners of hexagonal nut provide the main force point for wrench, however, under high frequency disassembly or impact load, the corners are prone to rounding (wear) due to metal fatigue or friction wear, and excessive tightening or mismatched tools (such as non-standard wrench) can also exacerbate corner wear, resulting in wrench slipping and causing disassembly difficulty. For example, the nut frequently disassembled in automobile repair slips due to corner wear, and needs to rely on impact tool or heating for auxiliary disassembly. The technical problem that the corner part of hexagonal nut is prone to wear has become a key bottleneck restricting equipment maintenance efficiency and safety.

[0004] Therefore, a new scheme is needed to solve this problem. UTILITY MODEL CONTENT

[0007] The utility model is further provided with: a sliding groove is formed in the nut body, a fixing piece is slidably connected in the sliding groove, and a clamping groove is formed in the corner part and communicated with the sliding groove.

[0008] The utility model is further provided with: the longitudinal section of the fixing piece is T-shaped, and the longitudinal section of the fixing piece is the same as the longitudinal section of the sliding groove.

[0009] The utility model is further provided with: a protruding strip is fixedly connected to the fixing piece, and a plurality of embedding grooves are formed in the groove wall of the sliding groove and clamped by the protruding strip.

[0010] The utility model further sets up: the convex stripe has elastic deformation characteristic.

[0011] The utility model further sets up: the cross section of convex stripe is semicircle.

[0012] The utility model further sets up: the recess is set up on the fixed part.

[0013] The utility model further sets up: the nut body adopts brass material to make.

[0014] Summarized above, the utility model has following beneficial effect:

[0015] Through setting up detachable angular part on the nut body, connect angular part in same connecting piece, when connecting piece is detached from the nut body, realize the replacement of angular part, avoid the angular of nut to slip after damaging, connecting piece's through -hole area is greater than the thread hole area of nut body simultaneously, can not affect the normal use of nut body.
