Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical parts technical field, concretely relates to a nut that can give way. BACKGROUND

[0002] The nut is screwed together with the bolt or screw rod to be used as a part for fastening, the inner wall of the nut is provided with an inner thread layer, the outer thread layer of the outer wall of the screw rod or bolt is engaged with the inner thread layer of the inner wall of the nut to screw the nut into and fix on the outer wall of the screw rod or bolt, and the depth of screwing of the nut can be adjusted through rotation, the fixed effect of the screwed nut is good, the screwing and taking out are simple, and the use flexibility is strong.

[0003] Although the above prior art can solve the corresponding technical problems, there are still some defects: in order to keep the screw rod in an upright state, a support rod is often arranged at the middle section of the screw rod to keep it upright, and after the existing nut is screwed into the screw rod, it cannot continue to rotate through the position where the support rod is connected with the screw rod, if it is necessary to pass through the position where the support rod is connected with the screw rod, the nut needs to be screwed in from the other end of the screw rod or the support rod needs to be removed, and the steps are more and the operation is very inconvenient. UTILITARIAN CONTENT

[0004] The utility model aims at the defects and deficiencies of the prior art, and provides a nut that can pass through the support rod of the screw rod and has few operation steps.

[0005] In order to achieve the above object, the utility model adopts the following technical scheme: a nut that can give way, comprising a nut body and a nut inner cavity penetrating the upper and lower ends of the nut body, the nut body is provided with a through groove with the same angle of the outer thread slope of the screw rod matched therewith, the through groove is a spiral groove structure extending from top to bottom along the nut body, after the nut body is screwed into the matched screw rod, the support rod is passed through the through groove when passing through the support rod of the screw rod.

[0006] Further improvement is that: the top surface of the nut body is provided with an upper flat piece.

[0007] Further improvement is that: the bottom surface of the nut body is provided with a lower flat piece.

[0008] The utility model discloses the beneficial effect that after adopting the above technical scheme is: the through groove that the nut body outer wall of the utility model is equipped with penetrates, and the angle of the through groove is same with the outer thread slope of the screw rod matched with the nut, and then in the rotating process, if the nut reaches the support rod position of the screw rod, can make the support rod enter the through groove, along with the rotation of the nut, the support rod passes through the through groove and moves relatively with the nut body, passes through the through groove and makes the nut body pass through the support rod, makes the nut passability greatly improve, need not take down the nut from the screw rod another end and rotate into again, convenient operation. BRIEF DESCRIPTION OF DRAWINGS

[0009] In order to more clearly illustrate the technical scheme in the embodiment of the utility model or prior art, below will to the drawing needed to use in the embodiment or prior art description simple introduction, obviously, the drawing in the following description only some embodiments of the utility model, for ordinary skilled person in the art comes, under the premise of not paying the creative labor, can also obtain other drawings according to these drawings.

[0010] Fig. 1 It is the structure schematic diagram of the utility model nut three-dimensional structure;

[0011] Fig. 2 It is the structure schematic diagram of the utility model nut front view. DETAILED DESCRIPTION

[0012] Now further illustrate the utility model with the specific embodiment and the drawing.

[0013] Referring to Figs. 1-2 The technical scheme adopted in the specific embodiment is: a nut allowing displacement, comprising a nut body 1 and a nut inner cavity 3 penetrating the upper and lower ends of the nut body 1, the nut body 1 is provided with a through groove 2 having the same angle as the outer thread slope of the screw rod matched therewith, the through groove 2 is a spiral groove structure extending from top to bottom along the nut body 1, after the nut body 1 is screwed into the matched screw rod, the screw rod moves along the outer thread, and when the support rod of the screw rod is passed, the support rod passes through the through groove 2, when using, the nut body 1 is screwed into the corresponding screw rod, the nut inner cavity 3 of the nut body 1 engages with the outer thread of the screw rod, and rotation can make the nut body 1 move along the outer thread of the screw rod, when the nut body 1 moves to the position of the support rod on the screw rod, the support rod can be clamped into the through groove 2 provided on the nut body 1 at this time, since the angle of the through groove 2 is same with the outer thread slope of the screw rod matched with the nut, along with the rotation of the nut body 1, the support rod of the screw rod can move relatively with the nut body 1 through the through groove 2 without being stuck, the nut body 1 passes through the support rod through the through groove 2, and the passability of the nut is greatly improved, when moving the nut, the nut need not be taken down from the other end of the screw rod and rotated into again, which is convenient to operate.

[0014] The nut body 1 top surface is provided with an upper flat piece 6, which is beneficial to make the nut body 1 upper surface more flat, and prevent protrusion to cause difficulty in installation or disassembly;

[0015] The nut body 1 bottom surface is provided with a lower flat piece 5, which is beneficial to make the nut body 1 lower surface more flat, and prevent protrusion to cause difficulty in installation or disassembly.

[0016] The working principle of the utility model is: when the utility model is used, the nut body 1 is screwed into the corresponding screw rod, the nut inner cavity 3 of the nut body 1 is engaged with the outer thread of the screw rod, and rotation can make the nut body 1 move along the outer thread of the screw rod; when the nut body 1 moves to the support rod position on the screw rod, the support rod can be clamped into the through groove 2 provided on the nut body 1 at this time; since the angle of the through groove 2 and the outer thread slope of the screw rod matched with the nut is the same, the support rod of the screw rod can move relatively with the nut body 1 through the through groove 2 without being stuck, the nut body 1 passes through the support rod through the through groove 2, and the nut passing property is greatly improved; when the nut is moved, the nut does not need to be disassembled and screwed into the screw rod from the other end, and the operation is convenient.

[0017] The utility model wants to protect the structure of the product, the model of each element is not the content of the utility model protection, and is the known technology, as long as the element on the market can realize the above-mentioned function of the utility model can be used as a kind of selection application. Therefore, the model of element and the like parameters are not described in detail in the utility model. The contribution of the utility model is that each element is combined scientifically.
