Description

Irregular nut elasticity spanner

Technical Field

An irregular nut tightening wrench belongs to the field of power tool equipment.

Background

The screw thread is divided into an internal screw thread and an external screw thread, the screw thread connection is a detachable connection formed by matching the internal screw thread and the external screw thread, the screw thread has various types, convenient disassembly and assembly, reliable work, easy processing and low cost, and is widely applied to various industries of national economy of all countries. The screw thread connection has good self-locking property, and the two parts can be firmly connected together after the screw thread connection is fastened by using a bolt spanner. Currently, various types of bolt wrenches are used to lock or unlock the nut, no matter which bolt wrenches are used, the nut needs to be locked on the bolt or unlocked from the bolt through a sleeve. The sleeve consists of a plurality of cylinders with concave hexagonal holes, and is provided with accessories such as a handle, a connecting rod and the like, and the concave hexagonal holes are all fixed. In the actual locking or loosening operation of the nuts on the bolts, the situation that the hexagonal nuts cannot be embedded into the concave hexagonal holes of the sleeves due to abrasion, corrosion or collision often occurs, so that one set of multiple sleeves is not suitable for being sleeved into the hexagonal nuts. For example, the hexagonal nuts on the railway sleeper are severely corroded due to the combined action of natural and artificial factors such as erosion of the rain, dew, snow and long-term month, wash water sprayed by a train, corrosion of toilet flushing water and the like, and are often irregularly corroded on one side. Therefore, when the concave hexagonal cylinder at the head of the bolt spanner is embedded, each side of the regular hexagon of the hexagonal nut on the sleeper cannot be tightly hooped, and the hexagonal nut is called as a small cap by railway maintenance workers, so that the hexagonal nut is difficult to disassemble, and the railway maintenance operation progress is seriously affected. Similar conditions frequently occur in various industries of national economy of all countries in the world, particularly in the places exposed outdoors, the efficiency of the locking or loosening operation of the nuts is seriously affected, innovative design is urgently needed, and tool equipment for conveniently and rapidly loosening irregular nuts is developed so as to adapt to the urgent needs of various industries of national economy of all countries in the world.

Detailed Description

The details and operation of the invention are described in detail in connection with the drawings of embodiments of the invention. It will be apparent that the described embodiments are merely one embodiment of the invention, and not all embodiments. Based on the embodiments of the present invention, other embodiments that may be obtained by those skilled in the art without making any inventive effort are within the scope of the present invention. The wrench consists of a handle 2, a small sleeve 3, a bolt sleeve 5, a plurality of clamping shafts 7 and the like; the handle 2 is formed by welding a transverse handle 2-1, a vertical rod 2-2, a small shaft 2-3, a flat key 2-4 and rotating blocks 2-5 together, and the rotating blocks 2-5 with the same number as the clamping shafts 7 are provided with stop blocks; a small sleeve 3 for axial positioning is sleeved between the bolt sleeve 5 and the small shaft 2-3 of the handle 2; the upper part of the bolt sleeve 5 is provided with a central hole penetrating into the small shaft 2-3 and a side hole penetrating into the cylinder of the clamping shaft 7, the upper end of the bolt sleeve 5 penetrates into the small shaft 2-3 and is fixed by a shaft retainer ring 6, the lower part of the bolt sleeve 5 is provided with a concave hexagonal cylinder which is larger than a standard nut, and the cylinder is provided with a screw hole for installing a set screw 4; the upper end of the clamping shaft 7 is provided with a shifting block attached to the stop block of the rotating block 2-5, and the lower cylinder is removed from the opposite side of the shifting block to form a truncated cone. The small shaft 2-3 of the handle 2 is inserted into the central hole of the rotating block 2-5 and positioned by the flat key 2-4 and then welded together, then the lower end of the vertical rod 2-2 is inserted and welded firmly, the semicircle at the upper end of the vertical rod 2-2 is jointed with the transverse handle 2-1 and then welded, the two ends of the transverse handle 2-1 penetrate into the sheath 1 convenient for handheld operation, and the circumference of the vertical rod 2-2 is stuck with the reflective strip 8 convenient for night use. In this embodiment, two clamping shafts 2 are provided, and two side holes penetrating through the cylinder of the clamping shaft 7 are provided at the upper end of the bolt sleeve 5. Obviously, the locking shaft 2 may be one, three, etc. according to the specific requirement of the nut locking or unlocking operation, and the side holes of the nut sleeve 3 may be correspondingly made into one, three, etc. The rotating block 2-5, the bolt sleeve 3 and the clamping shaft 7 are all made of high-quality alloy steel and subjected to strict heat treatment. When the nut is required to be locked or disassembled, whether the standard nut is locked or loosened or various corrosion nuts are disassembled, the elastic wrench is embedded into the nut to be locked or disassembled, so that the shifting block at the upper end of the clamping shaft 7 is attached to the stop block of the rotating block 2-5, the stop block of the rotating block 2-5 rotates clockwise, the shifting block of the clamping shaft 7 is shifted clockwise by the stop block of the rotating block 2-5, one side of the regular hexagon of the hexagon nut is tightly clamped by the round table body at the lower end of the clamping shaft 7, and the nut and the bolt can be rapidly locked; the baffle blocks of the rotating blocks 2-5 rotate anticlockwise to stir the shifting blocks of the clamping shaft 7 anticlockwise, so that the round table body at the lower end of the clamping shaft 7 tightly clamps one side of the regular hexagon of the hexagonal nut, and the hexagonal nut can be conveniently and rapidly disassembled no matter whether the side is rusted or not. For example, when railway ballast line ballast bed maintenance operation needs to be performed on locking or disassembling railway sleeper nuts, whether the standard railway sleeper nuts are locked or disassembled or the railway maintenance workers are disassembled to form a small cap-shaped corrosion hexagon nut, the elastic wrench is embedded into the railway sleeper nuts to be locked or disassembled, so that the shifting block at the upper end of the clamping shaft 7 is attached to the stop block of the rotating block 2-5, the block of the rotating block 2-5 is rotated clockwise, the shifting block of the clamping shaft 7 is shifted clockwise by the stop block of the rotating block 2-5, one edge of the hexagon nut is tightly hooped by the round table body at the lower end of the clamping shaft 7, the sleeper nuts and bolts on the sleeper can be rapidly locked, the railway fasteners are tightly pressed, and the steel rail is firmly fixed on the sleeper; the baffle blocks of the rotating blocks 2-5 rotate anticlockwise to stir the shifting blocks of the clamping shaft 7 anticlockwise, so that the round table body at the lower end of the clamping shaft 7 tightly clamps one side of the regular hexagon of the hexagonal nut, and the hexagonal nut can be conveniently and rapidly disassembled no matter whether the side is rusted or not. The beneficial effects of the invention are as follows: the problem that the hexagonal nut is severely corroded when the nut is tightly screwed in the operation of the bolt spanner, so that the hexagonal nut is difficult to fasten or disassemble is solved, the operation progress is greatly accelerated, the standard nut can be quickly screwed, various rusted nuts including sleeper nuts called as small caps by railway maintenance workers can be conveniently and rapidly disassembled, the production efficiency is high, the adaptability is strong, the conception is novel, the design is reasonable, the structure is simple, the operation is convenient, and the safety and the reliability are realized.
