Description

Novel non-loose bolt

The technical field is as follows:

the utility model relates to a fastener field, concretely relates to novel bolt does not become flexible.

Background art:

bolts and screws are the most common and common fastening parts in various devices, and are widely used. All need use the screw to carry out permanent fixed at mechanical equipment, vehicle, track, high-speed rotation or the equipment of motion etc., but most screw products at present all become flexible gradually and take off under the long-time vibration of machinery, in order to satisfy the user demand, the utility model provides a novel bolt that does not become flexible to solve not enough and shortcoming that prior art exists.

The utility model has the following contents:

the utility model aims at overcoming the shortcomings existing in the prior art and providing a novel bolt which does not loosen.

The utility model adopts the technical proposal that:

the utility model provides a novel bolt that does not become flexible, includes bolt main part, nut main part, butt ring, be equipped with the external screw thread in the bolt main part, bolt main part top the tooth's socket has been seted up on the external screw thread, be equipped with the tooth in the internal thread in the nut main part, but tooth adaptation plug-in advances the tooth's socket, nut main part threaded connection is in the bolt main part, butt ring cup joints in the bolt main part.

Preferably, the tooth socket is arranged at the lower half part of the external thread of the bolt main body, and the teeth are arranged at the upper half part of the internal thread of the nut main body.

Preferably, the pitch between adjacent ones of the tooth spaces is the same as the pitch between adjacent ones of the teeth.

Preferably, the butt ring is formed by rolling a metal sheet, and the butt ring can be glued or welded and fixed at the bottom of the bolt main body

The utility model has the advantages that: the utility model provides a current fixing bolt be because of vibrating the easy not hard up problem of when fastening the object, the tooth's socket and the effectual realization intermeshing of tooth ability that set up between the external screw thread of bolt main part external screw thread and nut main part for mutual block is fixed between bolt main part and nut main part, realizes fixing as and not becoming flexible, the utility model has the advantages of simple structure, the simple operation has apparent practicality.

In the figure: 001. bolt main part, 002, nut main part, 003, butt ring, 004, tooth socket, 005, tooth, 006, external screw thread, 007, internal screw thread.

The specific implementation mode is as follows:

the drawings are for illustrative purposes only and are not to be construed as limiting the patent; for the purpose of better illustrating the embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

As shown in fig. 1-7, a novel bolt that does not become flexible, including bolt main body 001, nut main body 002, butt ring 003, be equipped with external screw thread 006 on bolt main body 001, tooth socket 004 has been seted up on the external screw thread 006 on bolt main body 001 top, the shape of tooth socket 004 is the right angle waist trapezoidal shape of invering, tooth 005 is right angle trapezoidal shape (trapezoidal minimum angle is 45 °), this makes nut main body 002 threaded connection at bolt main body 001, during clockwise rotation, the hypotenuse at 45 jiaos of tooth socket 004 and the hypotenuse at 45 jiaos of tooth 005 can the relative slip, when nut main body 002 anticlockwise rotation, the right angle side of tooth socket 004 and the right angle side of tooth 005 will support 007 unable slip, be equipped with tooth 005 on the internal thread 002 in the nut main body, tooth 005 can adapt plug into tooth socket 004, nut main body 002 threaded connection is on bolt main body 001, butt ring 003 cup joints on bolt main body 001.

The further optimization of the scheme is set as follows: as shown in fig. 3-5, tooth socket 004 has been seted up in bolt main part 001 external screw thread lower half position, tooth 005 sets up in nut main part 002 internal screw thread upper half position, nut main part 002 can be twisted clockwise at bolt main part 001 top, when nut main part 002 receives decurrent power, tooth 004 on the bolt main part 001 top external screw thread 006 and tooth 005 on the internal screw thread 007 of nut main part 002 are separated, this makes nut main part 002 can continue smoothly that the needle screw thread is twisted on bolt main part 001, receive ascending power when nut main part 002, make tooth 005 on the internal screw thread 007 of nut main part 002 squeeze in the tooth socket 004 on bolt main part 001, realize the meshing joint.

The further optimization of this scheme sets up as: as shown in fig. 4 to 5, the pitch of the adjacent gullets 004 is the same as the pitch of the adjacent teeth 005, which allows the teeth 005 to be uniformly engaged with the gullets 004.

The further optimization of this scheme sets up as: as shown in fig. 6-7, the abutting ring 003 is formed by rolling a metal sheet, the abutting ring 003 can be glued or welded to the bottom of the bolt main body 001, when the bolt main body 001 fixes an object to be fixed, the metal sheet is firstly rolled to the bottom of the bolt main body 001 and then glued or welded, then the object is fixed through the bolt main body 001 and the nut main body 002, and the nut main body 002 is screwed tightly until the teeth 005 on the internal thread 007 of the nut main body 002 are squeezed into the tooth grooves 004 on the bolt main body 001 to realize meshing and clamping.

The utility model discloses a use method or principle do: fix butt ring 003 in bolt main part 001 bottom earlier, then treat fixed object with bolt main part 001 and connect, fix through nut main part 002, nut main part 002 spiral-wound closes tightly, realize the meshing joint in tooth's socket 004 on bolt main part 001 until tooth's socket 005 on the internal thread 007 of nut main part 002 crowds into, when dismantling bolt main part 001, demolish butt ring 003 earlier (as shown in fig. 7), then with the anticlockwise rotation of nut main part 002 atress downwards (tooth's socket 004 on bolt main part 001 top external screw thread 006 and tooth's 005 on the internal thread 007 of nut main part 002 are separated), it can to rotate out nut main part 002.

In the drawings, the positional relationships are depicted for illustrative purposes only and are not to be construed as limiting the present patent; it is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not limitations to the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
