Detailed Description

The invention is described in detail below with reference to the accompanying drawings, as shown in fig. 1-7: the utility model provides a hexagon bolt convenient to dismouting, screw rod 2 including spiral shell head 1 and the 1 bottom surface of perpendicular to spiral shell head, spiral shell head 1 is six arriss body structure, all be equipped with rectangle spout 3 on one of them pair of parallel side of

spiral shell head

1, 3 one ends of rectangle spout open the other end and seal, rectangle spout 3 interior slip has clamped rectangle slider 4,

rectangle slider

4 and 3 closed end of rectangle spout are equipped with first pressure spring 5 within a definite time, rectangle slider 4 one end is fixed with the handle bar 6 that is used for stretching out rectangle spout 3 open the end, open handle bar 6 lower part has draw-in groove 7, open recess 8 in 1 up end center department of spiral shell head, recess 8 and two 3 perpendicular intercommunications of rectangle spout, interior slip of recess 8 is provided with the fixture block 9 that is used for joint draw-in groove 7, be equipped with second pressure spring 10 between fixture block 9 and.

By adopting the technical scheme, the rectangular sliding grooves 3 are formed in one pair of parallel side surfaces of the screw head 1, the handle rods 6 are arranged in the rectangular sliding grooves 3, when a special wrench tool is lacked, the clamping block 9 can be pressed down, the handle rods 6 are popped out through the first pressure spring 5, the torque is increased by holding the two handle rods 6 on the two sides of the screw head 1, the hexagonal bolt is labor-saving to disassemble and assemble, the hexagonal nut can be conveniently disassembled and assembled by a worker without an extra tool under the condition that the hexagonal bolt is not screwed too tightly, and particularly, the hexagonal nut is convenient to disassemble and assemble in a narrow space and does not have enough places for using special disassembling and assembling tools such as a wrench and; the design of the rectangular sliding groove 3 and the rectangular sliding block 4 can realize that the rectangular sliding block 4 slides in the rectangular sliding groove 3, and can also avoid the handle rod 6 from rotating in the rectangular sliding groove 3 in the moving process so as to ensure that the clamping groove 7 corresponds to the clamping block 9.

As shown in fig. 4 and 6, a limiting block 11 is installed at the open end of the rectangular chute 3 in an interference manner, and an opening 12 for passing the handle bar 6 is formed in the limiting block 11.

Through adopting above-mentioned technical scheme, stopper 11 restriction rectangle slider 4 passes through, avoids rectangle slider 4 to break away from rectangle spout 3, and opening 12 internal diameter is greater than handle pole 6 external diameter to allow handle pole 6 to pass through and block rectangle slider 4 and pass through.

As shown in fig. 1 and fig. 3-6, a pressing rod 13 is fixed on the upper end surface of the latch 9, and the top end of the pressing rod 13 is located in the groove 8.

Through adopting above-mentioned technical scheme, press depression bar 13, can conveniently push down fixture block 9 to make fixture block 9 break away from draw-in groove 7, behind fixture block 9 no longer blockked handle pole 6, first pressure spring 5 popped out handle pole 6 one end.

As shown in fig. 1 and 3, a sealing element 14 for sealing the pressure rod 13 is clamped on the inner wall of the top end of the groove 8 in an interference fit manner, the sealing element 14 is in a hollow rectangular shape, the inner side of the sealing element 14 is in sealing sliding connection with the pressure rod 13 so as to prevent dust and rainwater from entering the groove 8, and the top end of the pressure rod 13 is located in the groove 8, so that the situation that the handle rod 6 is led to pop out due to mistaken impact on the pressure rod 13 can be.

When the clamping block 9 is clamped with the clamping groove 7, the handle rod 6 is accommodated in the rectangular sliding groove 3; when the clamping block 9 is separated from the clamping groove 7, the first pressure spring 5 pushes one end of the handle rod 6 out of the open end of the rectangular sliding groove 3.

The working principle of the embodiment is as follows: when a special wrench tool is lacked or the space for disassembling the bolt is not enough, and a hexagon nut needs to be disassembled and assembled, the pressure rod 13 is pressed downwards, the pressure rod 13 drives the clamping block 9 to descend, the second pressure spring 10 is compressed, the clamping block 9 is pressed downwards to the position below the rectangular sliding block 4 and the handle rod 6, the clamping block 9 is not clamped with the clamping groove 7, the clamping block 9 does not block the handle rod 6, one end of the handle rod 6 is ejected out of the open end of the rectangular sliding groove 3 under the elastic action of the first pressure spring 5, the handle rod 6 is exposed, the torque is increased by holding the two handle rods 6 at the two sides of the screw head 1, and the; after the handle bar 6 is detached, the two handle bars 6 can be pressed simultaneously, the handle bars 6 are pressed into the rectangular sliding groove 3, when the clamping groove 7 moves to the position above the clamping block 9, the clamping block 9 is jacked up by the second spring under the elastic action of the second pressure spring 10, and two ends of the clamping block 9 are clamped into the clamping grooves 7 of the two handle bars 6 respectively, so that the handle bars 6 are fixed, and the handle bars 6 are prevented from being popped up; during the process, the clamping block 9 is always positioned below the axis of the handle rod 6 and is abutted against the lower part of the axis of the handle rod 6, and the clamping block cannot pop out of the groove 8.

Above-mentioned technical scheme has only embodied the utility model discloses technical scheme's preferred technical scheme, some changes that this technical field's technical personnel probably made to some parts wherein have all embodied the utility model discloses a principle belongs to within the protection scope of the utility model.
