Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

In the present invention, the terms of orientation such as "inside and outside" used in the case where no description is given to the contrary mean inside and outside with respect to the outline of each member itself.

The utility model discloses a first aspect provides a nut box for install nut 20 in treating connecting piece 30, nut box 10 is including the U-shaped body that has circumference opening 11 and interior inner peripheral space 12, and circumference opening 11 is used for supplying nut 20 radially to pass in and out interior peripheral space 12, and the circumference profile of interior peripheral space 12 and the partial outer peripheral profile adaptation of nut 20, nut box 10 set up to be installed in treating connecting piece 30, and make interior peripheral space 12 corresponding with the first connecting hole 31 of treating connecting piece 30.

In the above description, the nut case 10 can be understood as a ring body having a circumferential section cut out, i.e., a U-shaped body, where the cut-out is a circumferential opening 11, and a space defined by the U-shaped body is an inner circumferential space 12 (refer to fig. 2).

It should be noted that the U-shaped body is not limited to a regular U-shape, and the structure similar to the U-shape is within the protection scope of the present invention, and the U-shaped body can be modified based on the U-shaped body. In addition, the circumferential profile of the inner peripheral space 12 may vary depending on the outer circumferential profile of the nut 20 to be mounted, for example, when the nut 20 is a hexagonal nut, the circumferential profile of the inner peripheral space 12 is a part of a regular hexagon (see the inner circumferential profile of the U-shaped side wall 14 in fig. 2). The nut box 10 of the present invention can be applied to any nut having a non-circular outer peripheral contour, such as a hexagon nut and a hexagon flange nut.

In installation, referring to fig. 2, the nut box 10 may be first installed at the first connection hole 31 of the to-be-connected member 30 such that the inner circumferential space 12 corresponds to the first connection hole 31, and then the nut 20 may be inserted into the inner circumferential space 12 of the nut box 10 through the circumferential opening 11 while the threaded hole 23 of the nut 20 coaxially corresponds to the first connection hole 31. Since the circumferential contour of the inner circumferential space 12 is adapted to a partial outer circumferential contour of the nut 20, the nut 20 can be circumferentially limited, thereby facilitating the subsequent connection of the bolt with the nut 20.

By adopting the technical scheme, on one hand, the inner peripheral space 12 of the U-shaped body can be used for accommodating the nut 20 and circumferentially limiting the nut 20, so that the nut and the bolt can be conveniently connected, and the nut box 10 can be suitable for any occasions; on the other hand, the circumferential opening 11 of the U-shaped body allows the nut 20 to radially enter and exit the inner circumferential space 12, which not only facilitates the mounting of the nut 20 to the nut box 10, but also enables the nut 20 to be detachable with respect to the nut box 10, enabling replacement of the nut 20, thereby avoiding an increase in cost.

In the present invention, the nut box 10 can be installed in the connecting member 30 by any suitable method. For example, the U-shaped body may be welded to the member to be connected 30 (see fig. 1 and 2), or the U-shaped body may be riveted to the member to be connected 30.

To facilitate installation of the nut box 10, the nut box 10 may also include one or more connecting portions that may be connected to or integrally formed with the U-shaped body. The nut case 10 may be fixedly connected (e.g., welded, riveted) to the member to be connected 30 by a connecting portion.

The utility model discloses in, in order to further improve nut box mounting nut's reliability, nut box 10 can include joint portion, and joint portion sets up to be able to install in axial one side of nut 20 when interior inner peripheral space 12 in nut 20.

The clamping portion can be in various embodiments as long as the clamping portion can be clamped on one side of the axial direction of the nut 20 to axially limit the nut.

For example, when the nut 20 is a nut without a flange surface, the engaging portion may be a substantially U-shaped flange extending from one axial side of the U-shaped body toward the center of the U-shaped body or a plurality of lugs arranged at intervals in the circumferential direction, and the flange or the plurality of lugs can be stopped at one axial side of the nut 20 and do not interfere with the threaded hole 23 of the nut 20.

For example, when the nut 20 is a flange nut, as shown in fig. 3, the nut 20 includes a cap 21 and a flange face 22 that are connected. In this case, according to an embodiment of the present invention, as shown in fig. 1 and 2, the nut case 10 may include a U-shaped peripheral wall 13 and a U-shaped side wall 14 connected to one side of the U-shaped peripheral wall 13 in the axial direction, an inner peripheral contour of the U-shaped peripheral wall 13 being configured to fit a part of an outer peripheral contour of the flange face 22, and an inner peripheral contour of the U-shaped side wall 14 being configured to fit a part of an outer peripheral contour of the cap 21, wherein the U-shaped side wall 14 is formed as the engaging portion capable of engaging with one side of the flange face 22 in the axial direction (see fig. 4).

Wherein, in order to further improve the limit of the nut box 10 to the nut 20, the nut box 10 is provided with: when the nut box 10 is arranged on the member to be connected 30 and the nut 20 is arranged on the nut box 10, one side of the flange surface 22 is tightly attached to the surface of the member to be connected 30, and the other side of the flange surface 22 is tightly abutted to the inner side surface of the U-shaped side wall 14. That is, the axial width of the U-shaped peripheral wall 13 is substantially equal to the thickness of the flange surface 22.

In the axial direction of the nut 20, the inner circumferential surface of the U-shaped sidewall 14 may be correspondingly engaged with a part of the outer circumferential surface of the cap 21 (see fig. 4), or may be correspondingly engaged with the entire outer circumferential surface of the cap 21. That is, the thickness of the U-shaped sidewall 14 may be less than the axial length of the cap 21 (see fig. 4), may be equal to the axial length of the cap 21, and may be greater than the axial length of the cap 21.

The utility model discloses in, under the condition that nut 20 is hexagon nut, for the convenience of nut 20 business turn over inner peripheral space 12, guarantee simultaneously that U-shaped lateral wall 14 can have great circumference contact range with nut 20 to improve the reliability of nut installation, preferably make U-shaped lateral wall 14's inner peripheral profile and the wherein four sides profile adaptation of block 21, as shown in fig. 4.
