Description

Technical Field

[0001] The utility model belongs to the technical field of machinery, in particular to a nut. Background Art

[0002] Slotted round nuts need to be used with stop washers. When in use, first insert at least one of the stop washer's limit plates into the guide groove of the screw, then insert at least one limit plate into the slot of the nut, and then use the remaining spring plates to press it against the workpiece. This will achieve the effect of locking the nut and preventing it from retreating. However, during the actual rotation process, the position of the limit plate is relatively fixed, and when the nut is tightened, it is easy for the slot and the limit plate to not correspond, which in turn makes it impossible for the limit plate to bend and press into the slot, making the anti-retreat effect less than expected. Summary of the Invention

[0003] The purpose of the utility model is to solve the above problems in the existing technology and to provide a nut with good anti-retraction effect.

[0004] The purpose of this utility model can be achieved through the following technical solutions:

[0005] A nut includes an annular body, the inner ring of the annular body is provided with a thread, the outer ring of the annular body is provided with at least four slots in a circumferential array, protrusions are formed between adjacent slots, each protrusion is provided with a plurality of first screw holes, the first screw holes are used to install a first screw; a first interval is provided between adjacent first screw holes on each protrusion; a plurality of second screw holes are provided on the outer surface of the annular body, the second screw holes are used to install a second screw; the plurality of second screw holes correspond one-to-one to the slots, and there is a second interval between adjacent first screw holes and second screw holes.

[0006] In the above nut, the outer ring of the annular body is provided with six slots in a circumferential array.

[0007] In the above nut, each of the protruding portions is provided with three first screw holes.

[0008] In the above nut, the width of the lower surface of the annular body is smaller than the width of the upper surface of the annular body.

[0009] In the above nut, the lower surface of the annular body is a rough anti-slip surface.

[0010] In the above nut, the first screw and the second screw can be hidden in the first screw hole and the second screw hole.

[0011] Compared with the prior art, this application has the following advantages:

[0012] In the present application, at least four slots are provided in the circumferential array of the outer ring. These slots are used for the subsequent limiting plates of the stop gasket to be inserted. When the limiting plates cannot correspond to the slots, the first screw can be installed in the first screw hole, or the first screw and the second screw can be installed on both the first screw hole and the second screw hole respectively, and then the limiting plate can be inserted between the two adjacent first screws, or between the first screw and the second screw, so as to limit the nut and prevent the nut from rotating.

[0022] The following is combined with Figures 1-4 The present application is further described with reference to the following specific examples:

[0023] First of all, it should be noted that in the description of this application, if the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and other directional words appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of this application; in addition, if the terms "first", "second", "third" and other numerical quantifiers appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", and "connected" appear, they should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, an interference fit, a transition fit and other limited connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium; therefore, for ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0024] Figure 1 What is shown in the figure is that the limiting piece of the stop washer is limited by the first screw and the second screw.

[0025] like Figures 1 to 4 As shown, a nut includes an annular body 2, the inner ring of the annular body 2 is provided with a thread 21, the outer ring of the annular body 2 is provided with at least four slots 22 in a circumferential array, and protrusions 23 are formed between adjacent slots 22, each protrusion 23 is provided with a plurality of first screw holes 231, and the first screw holes 231 are used to install the first screws 3; the first intervals between adjacent first screw holes 231 on each protrusion 23; the outer surface of the annular body 2 is provided with a plurality of second screw holes 24, and the second screw holes 24 are used to install the second screws 4; the plurality of second screw holes 24 correspond one-to-one to the slots 22, and there is a second interval between adjacent first screw holes 231 and second screw holes 24.

[0026] In the present application, at least four slots 22 are provided in the circumferential array of the outer ring. These slots 22 are used for the limiting piece 101 of the subsequent stop gasket 100 to be inserted. When the limiting piece 101 cannot correspond to the slot 22, the first screw 3 can be installed on the first screw hole 231, or the first screw 3 and the second screw 4 can be installed on both the first screw hole 231 and the second screw hole 24, and then the limiting piece 101 can be inserted between the two adjacent first screws 3, or between the first screw 3 and the second screw 4, so as to limit the nut and prevent the nut from rotating.

[0027] Specifically, six slots 22 are arranged in a circumferential array on the outer ring of the annular body 2 .

[0028] Compared with a smaller number of slots 22, six slots 22 can provide more options for the limiting piece 101 of the stop gasket 100 to be inserted. During the actual installation process, even if there is a certain degree of installation angle deviation, the limiting piece 101 has a greater probability of being successfully inserted into the slot 22, thereby improving the success rate of the stop gasket 100 and the nut to achieve the stopping function, making the stopping effect more reliable.

[0029] Specifically, each protrusion 23 is provided with three first screw holes 231 .

[0030] Specifically, the width a of the lower surface of the annular body 2 is smaller than the width b of the upper surface of the annular body 2 .

[0031] Specifically, the lower surface of the annular body 2 is a rough anti-slip surface.

[0032] The rough lower surface can increase the friction between the nut and the mounting plane. When the nut is tightened and subjected to external force, this increased friction can effectively prevent the nut from rotating or displacing relative to the mounting plane, thereby better maintaining its fixed state in the installation position.

[0033] Specifically, the first screw 3 and the second screw 4 can be hidden in the first screw hole 231 and the second screw hole 24 .

[0034] The screws can be hidden in the corresponding screw holes, making the surface of the entire nut and the parts connected thereto look neater and more beautiful.

[0035] During the delivery process, the first screw 3 and the second screw 4 can be pre-buried in the first screw hole 231 and the second screw hole 24, and can be screwed out when needed. Of course, this pre-buried operation is not necessary.

[0036] It should be noted that the above embodiments are only used to illustrate the present application and are not intended to limit the technical solutions described in the present application. Although this specification has described the present application in detail with reference to the above embodiments, ordinary technicians in this field should understand that technicians in the relevant technical field can still modify or make equivalent substitutions to the present application, and all technical solutions and improvements thereto that do not depart from the spirit and scope of the present application should be included in the scope of the claims of the present application.
