Abstract
The utility model discloses a tensile high-locking nut, which comprises a nut with a threaded hole, wherein the nut comprises a cylinder (1) with a threaded hole and a wrenching hexagon (2) with a hole, a locking deformation pit (4) is arranged on the cylinder (1), and a broken neck trench (3) is arranged between the locking deformation pit (4) and the wrenching hexagon (2). The utility model not only has the advantage of satisfying the assembling requirement of the narrow space, but also has the advantahes of convenient use, high connection reliability, and less possibility of looseness in use, and the like.
Description
Technical field
The utility model relates to a kind of tensile type Closely locking nut that is used for narrow assembly space, belongs to the technical field that is threaded.
Background technique
Nut is an internal thread fastening piece of finishing fastening function with the threaded male fastener adapted jointly.Since the bolt invention, nut also just has been born, and it and bolt are rated as a pair of heterosexual twins.But plain nut only plays the role of fastening, and does not have other function.Develop rapidly along with modern industry, nut has obtained extensive use in different field, especially in some assembly spaces narrow particular surroundings and occasion, nut has been proposed to satisfy the assembling of narrow space, the easy for installation in use again and high harsh requirement of connection reliability, and nut of the prior art is difficult to satisfy these harsh usage requirements.
The model utility content
The purpose of this utility model is: provide a kind of and can satisfy the assembling of narrow space, can reach easy to use again, connection reliability is high, be difficult for when using loosening tensile type Closely locking nut takes place, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: a kind of tensile type Closely locking nut of the present utility model comprises the nut that is provided with tapped hole, this nut is made up of cylindrical body that is provided with tapped hole and the twisting hexagon that is provided with the hole, on cylindrical body, also be provided with locking distortion hole, between locking distortion hole and twisting hexagon, be provided with disconnected neck groove.
Hole in the above-mentioned twisting hexagon is the smooth hole that does not have screw thread, and the aperture of smooth hole is more than or equal to the footpath, the end of screw thread in the cylindrical body tapped hole.
Owing to adopted technique scheme, the utility model is designed to cylindrical body to the change of the hexagon of plain nut, and twisting has partly kept the hexagon structure, and the two joint processes groove with the conventional machinery method for processing.Body is a cylindrical body, and the state space when having saved the plain nut assembling greatly seems compact more after being seated.The twisting hexagon is seated the back natural separation, has effectively realized assembling on the one hand, simultaneously, is seated the back natural separation, does not hinder body, has also discharged the useful space of expection.And after the place, locking distortion hole of cylindrical nut body carries out local artificial deformation, can prevent that like this nut from when connecting use unexpected rotation taking place, thereby realize highly reliable self-locking property.The utility model compared with prior art, the utility model not only has the advantage that can satisfy narrow space assembling, but also have easy to use, connection reliability is high, be difficult for taking place advantages such as loosening when using.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right TV structure schematic representation of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment of the present utility model: when making is used for the nut of narrow assembly space, make as follows, the nut that is about to be threaded the hole is made into by the cylindrical body that is threaded the hole and has the structure that the twisting hexagon in hole is combined into one, and between cylindrical body and twisting hexagon, make one and enclose disconnected neck groove, the degree of depth of disconnected neck groove can the size of needed screwing force be determined when using, when required screwing force is big, the degree of depth of its disconnected neck groove is just more shallow, otherwise dark; And the cylinder length that will form nut body is controlled at the scope less than the spatial altitude that will assemble, like this when using nut, exceed the twisting hexagon of assembly space height earlier by the instrument twisting, when screwing force reaches needed screwing force, the twisting hexagon disconnects from disconnected neck groove, realize natural separation, thereby discharge assembly space.
The structure of a kind of tensile type Closely locking nut of the present utility model comprises the nut that is provided with tapped hole, the screw thread of the tapped hole of this nut can be made by traditional standard method according to the needs that use, during concrete the making, nut is made into by cylindrical body 1 that is threaded the hole and the twisting hexagon 2 that has a hole forms, and the hole in the twisting hexagon 2 is made into the smooth hole 5 that does not have screw thread, the aperture of this smooth hole 5 is made into footpath, the end more than or equal to screw thread in cylindrical body 1 tapped hole; On cylindrical body 1, adopt the method for machining or the method for mould extrusion modling to produce locking distortion hole 4 then, locking distortion hole 4 can be made into the groove shapes of circular arc, also be made into the oval-shaped pit shape that is evenly distributed on the cylindrical body 1 by 2～4, this locking distortion hole 4 is in use, method by artificial method or instrument extruding is pushed easily at 4 places, locking distortion hole, make the tapped hole of nut produce certain deformation, thereby make nut in connecting the process of using, have higher self-locking property; Between locking distortion hole 4 and twisting hexagon 2, produce the neck groove 3 that breaks then.
Claims (2)
1. tensile type Closely locking nut, comprise the nut that is provided with tapped hole, it is characterized in that: nut is made up of cylindrical body that is provided with tapped hole (1) and the twisting hexagon (2) that is provided with the hole, on cylindrical body (1), also be provided with locking distortion hole (4), between locking distortion hole (4) and twisting hexagon (2), be provided with disconnected neck groove (3).
2. tensile type Closely locking nut according to claim 1 is characterized in that: the hole in the twisting hexagon (2) is the smooth hole (5) that does not have screw thread, and the aperture of smooth hole (5) is more than or equal to the footpath, the end of screw thread in cylindrical body (1) tapped hole.
