Description

Locking type torque nut convenient to install

Technical Field

The utility model relates to a machine part specifically is a lock-type torque nut of tightening type convenient to installation.

Background

Nuts are nuts that are screwed together with bolts or screws to function as fastening parts. The nut is a necessary element for all production and manufacturing machines, is a part for tightly connecting mechanical equipment, and is tightly connected with a screw with the same specification through an inner thread and a tooth to play a role of fixed connection. The variety of the nuts is various, and the nuts with national standard, German standard, English standard, American standard and Japanese standard are common.

At present, when machining, the two components are usually required to be tightly connected through some special parts, but the surfaces of the two components are kept flat after being installed, as is well known, the problem that a nut protrudes is necessarily existed when the nut and the bolt are used for connection, only the nut protrudes, the nut can be driven to be screwed by a spanner, and the common nut is not suitable for the components which need to keep flat surfaces after being assembled as mentioned above, so a tight-locking nut which is convenient to install is required.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a lock-type torque nut convenient to installation to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a lock-up formula torque nut convenient to installation, includes the nut body, and the nut body is hexagon nut, the ring channel has been seted up to nut body surface, and the inside one end processing outside leaning on of nut body has the unthreaded hole, and the inside other end processing of nut body has the screw hole, and screw hole and unthreaded hole linking department are in same position with the ring channel.

As a further aspect of the present invention: the surface of the annular groove is sleeved with a black leather ring.

As a further aspect of the present invention: the black leather ring is made of rubber.

As a further aspect of the present invention: the depth of the threaded hole is greater than that of the unthreaded hole, and the diameter of the unthreaded hole is greater than that of the threaded hole.

As a further aspect of the present invention: the nut body is made of aluminum alloy materials.

Compared with the prior art, the beneficial effects of the utility model are that: according to the nut, the annular grooves are formed in the outer surface of the nut body, so that the stress born by each part of the nut is inconsistent when the nut is subjected to external force, the outward-protruding part and the locking part are separated by continuously applying torque when the nut is completely screwed, the effect of locking type assembly is achieved, and the convenience and the surface flatness of assembly are greatly increased.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Referring to fig. 1-3, in the embodiment of the present invention, a locking type torque nut convenient for installation includes a nut body 1, the nut body 1 is a hexagon nut, an annular groove 2 is formed on an outer surface of the nut body 1, the nut body 1 is made of an aluminum alloy material, a unthreaded hole 4 is processed on an outer end of the nut body 1, a threaded hole 5 is processed on the other end of the nut body 1, a joint of the threaded hole 5 and the unthreaded hole 4 is located at the same position as the annular groove 2, a depth of the threaded hole 5 is greater than a depth of the unthreaded hole 4, a diameter of the unthreaded hole 4 is greater than the threaded hole 5, when the nut body 1 is installed, the nut body 1 is screwed in by a wrench, a thread in the threaded hole 5 cooperates with a bolt to drive the nut body 1 to screw, when the nut body 1 is screwed in place, the nut body 1 compresses a workpiece, and continues to apply torque, the moment that can bear is minimum, makes it fracture in ring channel 2 department under the shearing force effect, and protruding unthreaded hole 4 part separates with screw hole 5 parts, reaches the tight locking effect, has effectively solved current partial nut and has set up to the installation of lock formula, can have the problem of bulge when utilizing the spanner to screw.

Example 2

In order to make the technical solution in this application explain more detailed and complete, now make some supplements and explains on the basis of above-mentioned embodiment 1, so that the technical means that adopts in this application disclose more fully, specifically, supplement and explain partial technical feature be, annular groove 2 surface cover is equipped with a black leather collar 3, more closely step, black leather collar 3 adopts rubber material to make, plays the guard action to annular groove 2 through black leather collar 3, prevents to receive external force fracture when not assembling, plays the effect of blocking the spanner simultaneously, prevents that the spanner from exceeding annular groove 2 part and leading to turning round constantly.

The utility model discloses a theory of operation is: when the nut body 1 is screwed in place, the nut body 1 is driven to screw in by the matching of threads in the threaded hole 5 and the bolt, the nut body 1 compresses a workpiece after the nut body 1 is screwed in place, and torque is continuously applied, at the moment, because the annular groove 2 is formed at the joint of the threaded hole 5 and the unthreaded hole 4, the borne torque is minimum, the nut is broken at the annular groove 2 under the action of shearing force, the projected unthreaded hole 4 is separated from the threaded hole 5, so that the locking effect is achieved, the problem that the existing partial nut is arranged in a locking type installation, and the projected part exists when the nut is screwed by using the spanner is effectively solved, the torque nut has torque, when the torque reaches a certain value, the value is set in the production process, for example, the torque value required to be firmly pressed when the wire clamp is used for pressing two wires is 35 newtons, the torque is set to 35 newtons in the, the depth of the annular groove 2 is controlled during processing, and the wire clamp is installed by only twisting off the unthreaded hole 4 part of the torque nut all the time to firmly press the wire, so that the wire is not required to be broken due to no pressing.

It needs to explain very much in this application, the nut body is prior art's application, the mode that utilizes to set up the ring channel at nut body surface makes the nut receive stress nonconformity that each position can bear when external force, conveniently with the separation of evagination part with it when the nut is whole screwed, reach the effect of lock-up type assembly, greatly increased the convenience and the surface smoothness of assembly be the innovation point of this application, it has effectively solved current nut when the assembly and the problem that spanner laminating department can not complete screw in.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
