Abstract
Description
Technical Field
[0001] This application relates to cage nuts, and more particularly to cage nuts for use in painting lines. Background Technology
[0002] A cage nut is a special type of nut that is screwed onto a bolt or threaded rod for fastening. A cage nut consists of a cage and a nut held within the cage. The nut can move within the cage, allowing adjustment of the nut's position for proper installation. Utility Model Content
[0003] One way to use cage nuts is to secure them (e.g., by welding) to a bracket, which is then welded to a body crossbeam, and the seat rails are mounted to the body crossbeam. Holes on the bracket and seat rails are roughly aligned with the nuts in the cage nuts. The cage nuts are tightened by passing bolts or screws through the holes in the seat rails and brackets, thus securing the seat rails to the body crossbeam. When tightening with cage nuts, the position of the nuts can be adjusted so that the two seat rails are positioned parallel to each other.
[0004] After the component is installed onto the body crossbeam, it needs to pass through the painting line, and then the seat rails are fixed on the final assembly line. However, when passing through the painting line, because the cage and nut of the cage nut are loose, both the cage and nut are coated with paint. After the cage nut is coated with paint and then undergoes a drying process, the painted surfaces of the cage nut and the nut will stick together, preventing the nut from moving relative to the cage and thus rendering the cage nut unusable.
[0005] The inventors discovered that, in order to ensure the cage nut continues to function properly after passing through the coating line, one existing solution involves treating the nut with a non-stick coating, such as a Teflon surface treatment. This prevents the nut from sticking to the coating line and thus avoids adhesion to the cage nut, ensuring its proper functioning. However, Teflon is relatively expensive.
[0006] To address the aforementioned problems, according to one aspect of this application, a cage-type nut is provided. The cage-type nut includes a retainer, a nut, and a separator. The retainer includes a main body. The nut is configured to be moved within the retainer. The nut has a surface facing the surface of the main body of the retainer. The separator is disposed between the surface of the main body of the retainer and the surface of the nut to separate the surface of the main body of the retainer from the surface of the nut.
[0007] According to one aspect of this application, the separator has a height such that the surface of the body of the cage remains separated from the surface of the nut after the cage nut has passed the painting line.
[0008] According to one aspect of this application, the separator is configured such that, when the nut is not tightened, the separator separates the surface of the nut from the surface of the body portion of the retainer; and when the nut is tightened, the separator deforms such that the surface of the body portion of the retainer contacts the surface of the nut.
[0009] According to one aspect of this application, the height of the separator is greater than the sum of the thickness of the paint applied to the surface of the nut and the surface of the main body of the cage after the cage nut passes through the painting line.
[0010] According to one aspect of this application, the height of the separator is 0.2 mm to 1 mm, 0.2 mm to 0.7 mm, or 0.5 mm.
[0011] According to one aspect of this application, the separator is formed by stamping the main body of the cage.
[0012] According to one aspect of this application, the separating member is one or more protrusions provided on the surface of the main body of the retainer, the protrusions extending from the surface of the main body of the retainer.
[0013] According to one aspect of this application, the separating element is one or more protrusions disposed on the surface of the nut, the protrusions extending from the surface of the nut.
[0014] According to one aspect of this application, the end of the protrusion has an area such that after the cage nut passes the coating line, the protrusion can be separated from the surface of the nut facing it.
[0015] According to one aspect of this application, the end of the protrusion has an area such that after the cage nut passes the painting line, the protrusion can be separated from the surface of the body portion of the cage facing it.
[0016] According to one aspect of this application, the plurality of protrusions are symmetrically arranged on the surface of the main body portion of the holder where they are located, and the plurality of protrusions are identical.
[0017] According to one aspect of this application, the plurality of protrusions are symmetrically arranged on the surface of the nut on which they are located, and the plurality of protrusions are identical. Attached Figure Description

[0028] Various specific embodiments of this application will now be described with reference to the accompanying drawings, which form part of this specification. It should be understood that, where possible, the same or similar reference numerals used in this application refer to the same parts.
[0029] Figure 1A A perspective view of a cage nut according to an embodiment of this application, viewed from a first angle, is shown. Figure 1B A perspective view of a cage nut according to an embodiment of this application, viewed from a second angle, is shown. Figure 1C It shows Figure 1A The bottom view, Figure 1D It shows Figure 1A The front view.
[0030] like Figure 1A-1DAs shown, the cage nut 100 includes a cage 101 and a nut 102. The nut 102 is movable within the cage 101, for example, the nut 102 can move along a plane to adjust to a suitable position. The nut 102 moves within the cage 101 without moving out of the cage 101. The cage 101 includes a main body 103. The nut 102 is disposed facing the main body 103 of the cage 101. Surface 107 of the nut 102 faces surface 108 of the main body 103 of the cage 101.
[0031] To prevent the cage nut 100 from sticking together with its retainer 101 and nut 102 after passing through the coating line, for example, to prevent the opposing surfaces 107 of the nut 102 and 108 of the main body 103 of the retainer 101 from sticking together, this application provides a separator between the surface 108 of the main body 103 of the retainer 101 and the surface 107 of the nut 102 to separate the surface 108 of the main body 103 from the surface 107 of the nut 102. The separator is a part or component of a machine, where the part is an independent manufacturing unit and an indivisible individual component. The separator has a height such that the surface 108 of the main body 103 and the surface 107 of the nut 102 remain separated after the cage nut 100 passes through the coating line. For example, the height of the separator is greater than the sum of the thicknesses of the paint applied to the surfaces 108 of the main body 103 and 107 of the nut 102 after the cage nut 100 passes through the coating line. For example, the thickness of the coating applied to the surface 108 of the main body 103 and the surface 107 of the nut 102 after the cage nut 100 passes through the coating line is approximately 0.1 mm to 0.2 mm. The height of the separator can be set to 0.2 mm to 1 mm, 0.2 mm to 0.7 mm, or 0.5 mm.
[0032] As previously described, when the nut 102 is not tightened, the separating member separates the surface 108 of the main body 103 from the surface 107 of the nut 102. When the nut 102 is tightened, the separating member deforms so that the surface 108 of the main body 103 and the surface 107 of the nut 102 are at least substantially in contact, for example, substantially in complete contact, thereby ensuring a secure tightening. If, after tightening the nut 102, the separating member results in a small contact area between the surface 108 of the main body 103 and the surface 107 of the nut 102, for example, the surface 108 of the main body 103 and the surface 107 of the nut 102 only contact at the separating member and not at other locations, then the nut 102 will rotate under the action of external forces (e.g., vibration), that is, the nut 102 will be in a loose state, which can easily lead to damage to the cage nut 100 and prevent it from working properly. For example, the height of the separator cannot be set too high and the area of the separator's cross-section (which is approximately parallel to the surface 108 of the main body 103) cannot be set too large, because too high a height and too large an area may require the operator to apply a large force to deform the separator or even prevent the separator from deforming when tightening the nut 102, so that the surface 108 of the main body 103 is at least mostly in contact with the surface 107 of the nut 102.
[0033] like Figure 1A-1D As shown, the main body 103 of the cage 101 includes a through hole 104. The nut 102 moves within the cage 101 to substantially align with the through hole 104. In operation, fasteners, such as bolts or screws, can pass through the through hole 103 to tighten the nut 102, thereby enabling the fastening of desired components by means of the cage nut 100. The size of the through hole 104 in the main body 103 is larger than the size of the through hole in the nut 102. Figure 1C As shown, the through-hole 104 of the main body 103 is generally square. In other embodiments, the through-hole 104 of the main body 103 includes other suitable shapes, such as circular, etc. The retainer 101 includes a mounting portion 105, which includes a mounting member 106. The mounting portion 105 extends outward from the main body 103. The mounting member 106 can be mounted, for example, by welding, to a component. The mounting member 106 may be a protrusion provided on the bottom surface of the mounting portion 105. This protrusion can be formed by stamping the mounting portion 105.
[0034] For example Figure 1A-1DAs shown, one embodiment of the separating element is a protrusion 109 provided on the surface 108 of the main body 103 of the retainer 101, extending from the surface 108 of the main body 103 toward the surface 107 of the nut 102. The protrusion 109 separates the surface 108 of the main body 103 from the surface 107 of the nut 102. The end 110 of the protrusion 109 has an area such that after the cage nut 100 passes through the coating line, the protrusion 109 can, for example, easily separate from the surface 107 of the nut 102. If this area of the protrusion 109 is large, after the cage nut 100 passes through the coating line, the protrusion 109 may have difficulty separating from the surface 107 of the nut 102, thus failing to guarantee the normal operation of the cage nut 100. When tightening the nut 102, the protrusion 109 is deformed toward the surface 108 of the main body 103, so that the surface 108 of the main body 103 is in at least most contact with the surface 107 of the nut 102, for example, substantially in complete contact, thereby ensuring a secure tightening. Figure 1B-1C Four protrusions 109 are shown, but in other embodiments, the application may include other numbers of protrusions, such as one or more protrusions.
[0035] Figure 2A It shows Figure 1A The exploded diagram, Figure 2B It shows Figure 1B The exploded diagram.
[0036] like Figure 2A-2B As shown, four protrusions 109 are provided on the surface 108 of the main body 103 of the retainer 101. These four protrusions are substantially identical and symmetrically arranged on the surface 108 of the main body 103 to ensure balanced stress on the retainer 101 and the nut 102, preventing localized damage (e.g., deformation, cracking) that could result from uneven stress, which could cause the cage nut 100 to malfunction. In other embodiments, at least three protrusions 109 may be provided on the surface 108 of the main body 103. The protrusions 109 can be formed by stamping the main body 103 of the retainer 101. In other embodiments, the protrusions 109 can be formed by other suitable methods. The outer surface of the protrusion 109 may be arc-shaped or have other suitable shapes.
[0037] The nut 102 includes a fastening portion 201 and an engaging portion 202. The engaging portion 202 is generally plate-shaped and has a through hole 203. The through hole 203 is located approximately at the center of the engaging portion 202. The interior of the fastening portion 201 is through. The portion 204 of the fastening portion 201 away from the engaging portion 202 is cylindrical and has internal threads therein. The portion 205 of the fastening portion 201 near the engaging portion 202 is tapered for guiding fasteners, such as bolts or screws, into the portion 204 of the fastening portion 201 to fasten the nut 102. In other embodiments, the nut of this application includes other suitable structures.
[0038] In addition to the main body 103 and the mounting portion 105, the retainer 101 also includes a retaining portion comprising first wings 206 and second wings 207. The retainer 101 includes two first wings 206 extending from opposite sides of the main body 103 and substantially perpendicular to the main body 103 to restrict movement of the engagement portion 202 of the nut 102 along the plane 108 of the main body 103. The retainer 101 includes two second wings 207 extending from opposite sides of the main body 103 and arranged adjacent to the first wings 206. The second wings 207 are substantially U-shaped. The ends 208 of the second wings 207 are positioned above the main body 103 and spaced apart from the surface 108 of the main body 103 to restrict vertical movement of the engagement portion 202 of the nut 102. The sidewall 209 of the second wing 207 is substantially perpendicular to the main body 103 and is configured to restrict the movement of the engagement portion 202 of the nut 102 along the plane 108 of the main body 103. The main body 103, the first wing 206, and the second wing 207 of the retainer 101 form a receiving space to receive the engagement portion 202 of the nut 102. The engagement portion 202 of the nut 102 moves along the plane 108 of the main body 103 within this receiving space. In other embodiments, the retainer of this application includes other suitable structures.
[0039] Figure 3A A perspective view of a cage nut according to another embodiment of this application is shown. Figure 3B A front view of a cage nut according to another embodiment of this application is shown. Figure 3C It shows Figure 3A The exploded diagram.
[0040] like Figures 3A-3C As shown, another embodiment of the separator is a protrusion 109' provided on the surface 108 of the main body 103 of the retainer 101. Figures 3A-3C The structure of the cage nut 100' in Figure 1A-1DThe structure of the cage nut 100 is roughly the same as that of the cage nut 100. The difference is that in the cage nut 100, a protrusion 109 is provided on the surface 108 of the main body 103 of the retainer 101, while in the cage nut 100', a protrusion 109' is provided on the surface 107 of the nut 102. The structure of the cage nut 100' which is the same as that of the cage nut 100 will not be described again here.
[0041] like Figures 3A-3C As shown, a protrusion 109' extends from the surface 107 of the nut 102 toward the surface 108 of the body portion 103 of the cage 101. The protrusion 109' separates the surface 108 of the body portion 103 of the cage 101 from the surface 107 of the nut 102. Furthermore, the protrusion 109' has a height such that the surface 108 of the body portion 103 remains separated from the surface 107 of the nut 102 after the cage nut 100' passes the painting line. The end 110' of the protrusion 109' has an area such that after the cage nut 100' passes the painting line, the protrusion 109' can, for example, easily separate from the surface 108 of the body portion 103 of the cage 101. If the area of the protrusion 109' is large, after the cage nut 100' passes through the painting line, the protrusion 109' may be difficult to separate from the surface 108 of the main body 103 of the cage 101, thus failing to ensure the normal operation of the cage nut 100'. Figures 3A-3C Four protrusions 109' are shown, but in other embodiments, the application may include other numbers of protrusions, such as one or more protrusions, such as at least three protrusions.
[0042] Furthermore, in this application, another embodiment of the separator is a protrusion provided on both the surface 108 of the main body 103 of the retainer 101 and the surface 107 of the nut 102, to separate the surface 108 of the main body 103 from the surface 107 of the nut 102. In other embodiments, the separator of this application also includes other suitable structures to implement the functions described above.
