Description

Sleeve structure of nut wrench

Technical Field

The utility model relates to a sleeve structure of a nut wrench.

Background

In the field of mechanical assembly, the most basic operation of tightening or loosening nuts is usually to use a wrench or a socket as an auxiliary tool, thereby reducing the difficulty of operation and saving physical strength. Traditional sleeve, its inner chamber generally be with the outer angle matched with polygon structure of nut, the sleeve inner chamber of this kind of structure is generally bigger than the nut partially to the cover that can relax is established on the nut, but in the use, the stress point often on the outer angle of nut, easily causes the outer angle of nut to warp and produces the button head phenomenon, damages the nut.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that the inner cavity of a traditional sleeve is generally of a polygonal structure matched with the outer corner of a nut, the inner cavity of the sleeve of the structure is generally larger than the nut so as to be easily sleeved on the nut, but in the using process, the stress point is always on the outer corner of the nut, the outer corner of the nut is easy to deform to generate a round head phenomenon, and the nut is damaged.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a nut spanner's sleeve structure, establishes the sleeve body in the nut periphery including the cover, be equipped with along radial bellied spacing platform inwards in the hole of sleeve body, the quantity of spacing platform is a plurality of, a plurality of spacing platform is along circumference evenly distributed, when the sleeve body rotates, spacing platform supports to be held on the side of nut and drive the nut is followed the sleeve body rotates in step.

Further: the number of the limiting tables is the same as that of the side faces of the nut, and each limiting table is adjacent to one side face of the nut.

Further: the top of spacing platform is provided with the tooth's socket of indent, the tooth's socket sets up along the axial.

The nut wrench has the beneficial effects that the sleeve structure of the nut wrench adopts the limiting table structure protruding in the inner hole of the sleeve, the limiting table is in abutting contact with the side surface of the nut in the using process, and the stress point is positioned on the side surface of the nut, so that the phenomenon of round head of the outer angle of the nut is avoided; meanwhile, compared with a polygonal structure matched with the outer corner of the nut, the structure reduces the contact surface with the nut, and an operator can conveniently sleeve the sleeve on the nut.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention. On the contrary, the embodiments of the utility model include all changes, modifications and equivalents coming within the spirit and terms of the claims appended hereto.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", and the like, indicate orientations and positional relationships based on the orientations and positional relationships shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be considered as limiting the present invention.

Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, e.g., as being fixed or detachable or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art. In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.

Any process or method descriptions in flow charts or otherwise described herein may be understood as representing modules, segments, or portions of code which include one or more executable instructions for implementing specific logical functions or steps of the process, and alternate implementations are included within the scope of the preferred embodiment of the present invention in which functions may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those reasonably skilled in the art of the present invention.

As shown in fig. 1, 2 and 3, the present invention provides a sleeve structure of a nut wrench, including a sleeve body 2 sleeved on an outer periphery of a nut 1, wherein a plurality of limiting tables 3 protruding inward in a radial direction are arranged in an inner hole of the sleeve body 2, the plurality of limiting tables 3 are uniformly distributed along a circumferential direction, and when the sleeve body 2 rotates, the limiting tables 3 abut against a side surface of the nut 1 and drive the nut 1 to rotate synchronously along with the sleeve body 2.

Adopt bellied spacing platform 3 structure in the sleeve hole in this scheme, the contact is supported with the side of nut 1 to spacing platform 3 in the use, and the stress point is located the side of nut 1, and then has avoided the emergence of 1 external angle button head phenomenon 6 of nut.
