Detailed Description

Referring to fig. 1 to 7, the present invention: a novel bolt comprises a bolt head 1, a threaded rod 2 and a nut 5, wherein a through groove I30 and a through groove II40 are arranged on one end face of the bolt head 1, a sliding groove I31 is arranged on the side wall of the through groove I30, a sliding groove II41 is arranged on the side wall of the through groove II40, a sliding block I3 and a sliding block II4 are respectively arranged in the through groove I30 and the through groove II40, the sliding block I3 and the sliding block II4 can prevent the through groove I30 and the through groove II40 from being collided and damaged when not in use, foreign matters can be prevented from falling into the through groove I30 and the through groove II40, a sliding strip I40 in sliding fit with the sliding groove I40 is arranged on the sliding block I40, a sliding strip II40 in sliding fit with the sliding groove II40 is arranged on the side wall of the sliding block I40, a through groove III 40 is provided with a through groove III 40 in sliding fit; threaded rod 2 includes fixed part 10 and detachable part 23, fixed part 10 is fixed in on bolt head 1 keeps away from the face that leads to groove I30, logical groove II40, and fixed part 10 keeps away from the one end of bolt head 1 and is equipped with the cross-section and be hexagonal slot 14, and fixed part 10 outer wall is equipped with the through-hole I11 that passes slot 1414, detachable part 23 one end is equipped with slot 14 sliding fit and the cross-section is hexagonal pole 20, and the cross-section is hexagonal slot 14, pole 20 and mutually supports and can drive detachable part 23 when making bolt head 1 rotate, is equipped with on the pole 20 with the corresponding through-hole II21 of through-hole I11, be equipped with dowel 12 in through-hole I11, the through-hole II 21. The cooperation of the through hole I11, the through hole II21 and the dowel 12 can not only prevent the fixed part 10 from accidentally separating from the detachable part 23, but also drive the detachable part 23 to rotate when the bolt head 1 rotates. The threads uniformly arranged on the outer wall of the threaded rod 2 enable the threaded rod to be used alone in the absence of a nut.

Lead to groove I30 bottom and be equipped with oiling pipe 13, oiling pipe 13 passes bolt head 1, fixed part 10 in proper order and extends the terminal surface that fixed part 10 was equipped with slot 14, and oiling pipe 13 that extends fixed part 10 can prevent that lubricating oil when flowing into oiling groove 22 through oiling pipe 13, along the junction roll-off of fixed part 10 and detachable portion 23, can't reach lubricated effect, detachable portion 23 is equipped with "L" shape oiling groove 22, and oiling groove 22 one end is located detachable portion 23 and is equipped with the terminal surface that pole 20, and detachable portion 23 lateral wall is located to the other end. Lubricating oil is injected into the oil injection pipe 13 and the oil injection groove 22, so that the bolt which cannot rotate due to corrosion can be lubricated and can easily rotate.

One end face of the screw cap 5 is hinged with two U-shaped pieces 50, and the ports of the two U-shaped pieces 50 are arranged oppositely. Turning up the two "U" shaped pieces 50 provides a point of effort for the hand to turn the nut 5 by hand.

Preferably, the depth of the through groove I30 is greater than that of the through groove II40, and the depth of the through groove III33 is the same as that of the through groove II 40.

When it is desired to use the bolt, the slot 14 of the fixed part 10 is pressed against the rod 20 of the removable part 23, during which the rod 20 slides into the slot 14 and the filler pipe 13 is inserted into the filler groove 22; inserting the dowel 12 into the through hole I11, inserting the dowel 12 into the through hole II21 along the through hole I11 on one side of the fixed part 10, and finally inserting the dowel 12 into the through hole I11 on the other side of the fixed part 10, wherein the through hole I11, the through hole II21 and the dowel 12 are connected to enable the fixed part 10 and the detachable part 23;

whether the sliding block I3 and the sliding block II4 are removed or not is selected according to the used tools, when a 'straight' screwdriver is used, the sliding block II4 is removed in a sliding mode, and in the process, the sliding strip II42 slides along the sliding groove II41 and the sliding groove III 34; when the cross screwdriver is used, the sliding strip II42 is firstly slid and taken down, then the sliding strip I3 is slid and taken down, and in the process, the sliding strip I32 slides along the 31 sliding groove I; when the wrench is used, the screw head can be directly screwed without taking down the slide block I3 and the slide block II 4. In the process of using the spanner, the slide block I3 and the slide block II4 play a role in filling and supporting the bolt head 1, and prevent the bolt head 1 from being deformed by the spanner force to cause damage.

When the nut 5 needs to be matched with a bolt for use, the nut 5 can be directly screwed by a wrench, or the two U-shaped pieces 50 can be turned over, so that the U-shaped pieces 50 provide acting points for the hands of a user, and the user can screw the nut 5 by the hands without an auxiliary tool wrench.

When the bolt can not be screwed out from the fixed position due to corrosion, the sliding block I3 and the sliding block II4 are taken down in a sliding mode, lubricating oil is injected into the oil injection pipe 13, the lubricating oil flows into the oil injection groove 22 along the oil injection pipe 13 and finally flows into the detachable portion 23, and the lubricating threaded rod 2 is taken out conveniently.

When the bolt head 1 is damaged, the dowel 12 is taken out of the through hole I11, during which the dowel 12 slides along the through hole I11 on one side of the fixing part 10 into the through hole II21 and finally out of the through hole I11 on the other side of the fixing part 10; the bolt head 1 is removed and replaced, the slot 14 in the fixing part 10 of the new bolt head 1 is pressed against the rod 20 in the detachable part 23, and the dowel 12 is inserted into the through hole I11 and the through hole II21 and fixed. Preferably, the fixing portion 10 is integrally formed with the bolt head 1.

Due to the adoption of the technical scheme, the problems that the using mode of the bolt is single, the bolt head 1 cannot be replaced and the bolt is difficult to disassemble after being corroded are effectively solved, the novel bolt is reasonable and simple in structural design, and the hexagonal bolt head 1 is slidably connected with the sliding block I3 and the sliding block II4 through the through groove I30 and the through groove II40, so that the novel bolt can be suitable for various tools; the fixing part 10 is provided with a slot 14, the detachable part 23 is provided with a rod 20, the fixing part 10 and the rod 20 are respectively provided with a through hole I11 and a through hole II21, the through hole I11 and the through hole II21 are matched with the dowel 12 to facilitate the detachment of the bolt head 1, the cross sections of the slot 14 and the rod 20 are hexagonal, so that the slot 14 and the rod 20 can rotate in a matched mode, meanwhile, the dowel 12 is connected with the through hole I11 and the through hole II21, and when the bolt head 1 rotates, the detachable part 23 can be driven to rotate through the dowel 12; an oil filling pipe 13 extends from the fixed part 10, the oil filling pipe 13 is inserted into an oil filling groove 22 formed in the detachable part 23, and the oil filling pipe 13 is communicated with the bottom of the through groove I30, so that lubricating oil can flow into the side wall of the threaded rod 2 from the oil filling pipe 13 through the oil filling groove 22, so that the rusted part of the threaded rod 2 is lubricated, and the threaded rod 2 can be conveniently taken out; the nut 5 is provided with the U-shaped sheet 50, the U-shaped sheet 50 can be erected when the bolt is disassembled, a user can conveniently fix the nut 5 by hands, when the nut 5 needs to be disassembled, the nut 5 can be manually disassembled by the user through the U-shaped sheet 50, and the U-shaped sheet 50 can be prevented from being erected when the bolt exceeds the nut 5.
