Abstract
The invention relates to a locknut which comprises a nut body, and is characterized in that a friction surface for increasing the frictional force between the end surface of the nut body and a contact surface is arranged on the end surface of the nut body. Because the invention adopts the technical scheme that a friction surface is additionally arranged on the end surface of the common nut, a larger frictional force exists between the nut and the contact surface after installation and use, thus the nut can not loosen easily and achieves the purpose of locking when a connector is in a vibration environment for a long time. When the nut is removed, only a wrench is used for overcoming the snap-in force to remove the nut easily, so that the invention has the advantages of good locking effect, simple and reliable structure, no need of special tools for installation, wide applicable environment, no requirements for special technical parameters in design, and convenience in manufacture.
Description
Technical field
The present invention relates to and belongs to fastening piece manufacturing technology field, particularly a kind of lock nut.
Background technique
Traditional connecting body that is threaded in is in the long-term vibration environment, loosening easily, engineers and technicians do a lot of work aspect locking thread for this reason, existing thread connection anti-loose mostly adopts patterns such as increasing check washer, special-shaped screw thread, and not only number of parts increases, processed complex, and need special tool to carry out during installation or removal, complex structure not only, reusability is poor, and uses inconvenience.
Summary of the invention
The present invention provides a kind of reliable in structure, anti-loosing effect obvious, easy to use for solving the technical problem that exists in the known technology, and does not need to use the lock nut that special tool can installation or removal.
The technological scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of lock nut comprises nut body, it is characterized in that: the end face of described nut body is provided with the rubbing surface of the frictional force between increase and the surface of contact.
The present invention can also be by the following technical solutions:
It is the flanged surface of one that one end of described nut body is provided with nut body, is provided with rubbing surface on flanged surface.
Described rubbing surface adopts ratchet structure.
Described ratchet is a helical teeth.
Described ratchet is uniform setting on circumference.
Described nut body adopts hexagon nut.
Advantage and good effect that the present invention has are: because the present invention adopts technique scheme, promptly adopt common nut, end face at nut has additional rubbing surface, installing and using bigger frictional force of existence between back nut and the surface of contact like this, thereby be in the long-term vibration environment at connecting body, be difficult for becoming flexible, reach locking purpose.At disassembly-type, can smoothly it be disassembled as long as adopt spanner to overcome snap-in force, so the present invention has good anti-loosing effect, and have simple in structurely, reliable, do not need special tool during installation, advantage such as suitable environment is extensive; The requirement of the no special technique parameter of design simultaneously, the advantage of being convenient to make.

Embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Embodiment 1:
See also Fig. 1 and Fig. 2, a kind of lock nut, comprise nut body 1, nut body adopts hexagon nut, the end face of described hexagon nut is provided with the rubbing surface 1-1 of the frictional force between increase and the surface of contact, this rubbing surface is preferably ratchet 1-2 structure, and described ratchet is a helical teeth, and ratchet is uniform setting on circumference.
Embodiment 2:
See also Fig. 3 to Fig. 7; A kind of lock nut, comprise nut body 1, nut body adopts hexagon nut, it is the flanged surface 2 of one that one end of described hexagon nut is provided with hexagon nut, on flanged surface 2, be provided with rubbing surface 2-1, this rubbing surface is preferably ratchet 2-2 structure, and described ratchet is a helical teeth, and ratchet is uniform setting on circumference.
See also Fig. 8, user mode: promptly adopt common hexagon nut, have additional rubbing surface at the end face of hexagon nut, installing and using bigger frictional force of existence between back nut and the surface of contact like this, thereby be in the long-term vibration environment at connecting body, be difficult for becoming flexible, reach locking purpose.At disassembly-type, can smoothly it be disassembled as long as adopt spanner to overcome snap-in force.
Advantages such as therefore the present invention has good anti-loosing effect, and has simple in structurely, reliable, does not need special tool during installation, and suitable environment is extensive; The requirement of the no special technique parameter of design simultaneously, the advantage of being convenient to make.
Although in conjunction with the accompanying drawings the preferred embodiments of the present invention are described above; but the present invention is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present invention; not breaking away under the scope situation that aim of the present invention and claim protect, can also make a lot of forms, these all belong within the protection domain of patent of the present invention.For example embodiment 1 and embodiment's 2 combination; Nut body also can adopt tetragonal nut etc.
