The outer wall of the rotary drum 11 is fixed with a slide block 15, and the base 1 is provided with a spiral chute 16 matched with the slide block 15. Specifically, referring to fig. 1, a sliding block 15 is fixed on the outer surface of the lower end of the rotating drum 11 with an inclined surface, i.e., a wedge-shaped end, an extending groove 2 for the rotating drum 11 to move up and down and rotate is formed on the base 1, and a spiral sliding groove 16 matched with the sliding block 15 is formed on the inner wall of the extending groove 2.
Connecting plate 10 is installed at the top of rotary drum 11, and the dismouting head is fixed in connecting plate 10 lower surface. A hand pressure pad 13 is mounted on the upper surface of the connecting plate 10. The hand pressure pad 13 can be made of an inflatable bag, a rubber block or a sponge block, so that the comfort degree of the hand when the hand is pressed is improved.
The detachable head further includes a fixed cylinder 14 and a connecting rod 12, the connecting rod 12 is detachably connected to the fixed cylinder 14, the connecting rod 12 is connected to the plug 3 or integrally formed with the plug 3, in this embodiment, referring to fig. 1 and 2, the head of the bolt has an inner hexagon, and the plug 3 is matched with the inner hexagon.
In embodiment 2, referring to fig. 3, for the bolt head being externally hexagonal, the plug 3 can be adapted to have an internal hexagonal plug to complete the separation of the bolt and nut. In the same manner as in embodiment 1, the connecting rod 12 is detachably connected to a fixed cylinder 14, and the connecting rod 12 can be integrally formed with the plug 3.
The working principle is as follows: when carrying out nut and bolt split, like figure 1, place the upper surface at base 1 with the bolt of treating the split earlier to make the lower extreme of bolt insert in socket 5, the nut is located between two splint 9 this moment, and splint 9 sets up the shape in figure 2, can better carry out the centre gripping to the nut.
After placing the bolt and the nut of treating the split, put connecting rod 12 notch of the rotary drum 11 that will have the inclined plane and face extension groove 2, make the rotary drum 11 that has the inclined plane promptly wedge end can vertical downstream, after finishing placing, press down hand pressure pad 13, press down the back, connecting plate 10 can be pressed and is moving downwards, through the inclined plane cooperation between the inclined plane of the rotary drum 11 bottom that has the inclined plane and the wedge 7, make two wedge 7 move in opposite directions, thereby promote splint 9 and move in opposite directions, and then press from both sides the nut of placing between two splint 9.
At this time, the positions of the bolt and the nut are fixed, the connecting plate 10 will continue to move downwards as the connecting plate 10 is continuously pressed downwards, the drum 11 with the inclined surface will continue to move downwards, but the position of the wedge 7 will not change, and the wedge 7 is staggered from the position of the drum 11, so that the drum 11 can continue to move downwards, the base 1 is provided with an extending groove 2 for the drum 11 with the inclined surface to extend into, in the process, the fixing cylinder 14 with the plug 3 mounted at the air bottom will gradually approach to the upper end of the bolt, and finally inserted into a groove (such as a hexagonal groove in figures 1 and 2) matched with the upper end of the bolt, the plug 3 can be replaced by inserting the connecting rod 12 and the fixing cylinder 14, so as to adapt to different bolts, the plug 3 is inserted into the groove of the bolt, the drum 11 with the inclined surface is rotated, and the fixing cylinder 14 rotated with the plug 3 can drive the plug 3 to rotate and act on the bolt, the bolt is driven to rotate, and the nut is clamped by the clamping plate 9 at the moment, so that the bolt and the nut can be separated after the rotary drum 11 with the inclined plane is continuously rotated.
After the rotary drum 11 with the inclined plane is continuously pressed downwards, the sliding block 15 can be embedded into the spiral sliding groove 16, the hand pressure pad 13 is pressed downwards at the moment, so that the rotary drum 11 with the inclined plane can rotate, the clamping plate 9 is matched with the plug 3, the nut and the bolt are separated, and labor is saved and convenience is achieved. Simultaneously, when connecting between nut and the bolt and too closely lead to changeing motionlessly, accessible sledgehammer carries out in succession and quick striking to connecting plate 10 to produce certain vibrations, make to connect lax between too inseparable nut and the bolt, so that dismantle convenient to use.
In conclusion, the nut and bolt disassembling device is used for disassembling bolts and nuts, and is convenient to operate, fast, efficient, simple in structure, low in manufacturing cost and easy to popularize.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
