[0038] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0039] The adjustable nut 100 according to an embodiment of the present utility model will be described below with reference to the drawings.

[0040] As Figure 1 and Figure 2 shown, the adjustable nut 100 according to an embodiment of the present utility model includes a base 1, a cover plate 2 and a nut member 3.

[0041] Specifically, as Figure 1 and Figure 2 shown, the base 1 has a through hole 13. The base 1 and the cover plate 2 are stacked and spaced apart. The cover plate 2 has a floating hole 21 disposed opposite to the through hole 13. As Figure 1 and Figure 5 shown, the nut member 3 includes a fixing plate 31 and a nut portion 32. The nut portion 32 is annular and is disposed through the floating hole 21. The nut portion 32 of the nut member 3 can move in the floating hole 21. The floating hole 21 on the cover plate 2 defines a movement space of the nut member 3 in a direction perpendicular to the axis of the floating hole 21. The fixing plate 31 is sleeved outside the nut portion 32 and is connected to one end of the nut portion 32 facing the base 1. The fixing plate 31 is located between the base 1 and the cover plate 2. The base 1 and the cover plate 2 jointly define a movement space of the nut member 3 in a direction along the axis of the floating hole 21. The nut member 3 is movable along the arrangement direction of the base 1 and the cover plate 2 and is movable in a plane perpendicular to the arrangement direction of the base 1 and the cover plate 2. The free movement space of the nut member 3 can provide an assembly tolerance dimension that meets the requirements.

[0042] In addition, the cover plate 2 and the base 1 are separate processed parts and connected, and the separate processed parts can be easily manufactured. The present application designs the base 1 and the cover plate 2 as separate processed parts, so that each component can be assembled after surface anti-corrosion coating and plating treatment, and the entire adjustable nut 100 can be prevented from being subjected to surface anti-corrosion coating and plating treatment as a whole, thereby avoiding the adhesion of the position with a small gap between the cover plate 2, the nut part 3 and the base 1, which affects the floating of the adjustable nut 100, and can solve the problem of the coating and plating falling off at the pasting position of the nut part 3 of the adjustable nut 100 after floating, which can effectively improve the surface quality of each component, reduce the risk of rust and torque attenuation problems, and effectively extend the service life of the adjustable nut 100.

[0043] For example, Figure 10 As shown, the cover plate 2 and the base 1 are assembled by an inverted structure, the cover plate 2 and the base 1 are spaced apart, and the space between the cover plate 2 and the base 1 constitutes a floating space along the axis direction of the through hole 13, so that the fixing plate 31 of the nut member 3 can be adjusted and moved therein, and the nut portion 32 of the nut member 3 can also be adjusted and moved in the floating hole 21 of the cover plate 2 in a direction perpendicular to the axis direction of the floating hole 21. When connected by the adjustable nut 100, the base 1 can be fastened to the fixing member 7, and the entire adjustable nut 100 and the fixing member 7 are assembled together. The fixing member 9 to be fixed can be located on the side of the fixing member 7 away from the adjustable nut 100, and the fastening bolt 8 can pass through the fixing member 9 to be fixed, through the through hole 13 of the base 1, enter the nut portion 32 of the nut member 3, and be threadedly connected with the nut portion 32, thereby realizing the fastening connection between the fixing member 7 and the fixing member 9 to be fixed.

[0044] According to the adjustable nut 100 of the utility model embodiment, by designing the base 1 and the cover plate 2 as separate processed parts, the various components can be assembled after surface anti-corrosion coating and plating treatment, which can avoid the sticking of components caused by the surface anti-corrosion coating and plating treatment of the entire adjustable nut 100 as a whole, thereby solving the problem of inconvenience in moving the nut part 3 and the shedding of coating caused by the movement of the nut part 3, and further can effectively improve the surface quality of each component and reduce the risk of rust and torque attenuation problems.

[0045] In some embodiments of the present invention, the cover plate 2 and the base 1 are connected by snapping, thereby simplifying the connection between the cover plate 2 and the base 1 and improving the reliability of the connection between the cover plate 2 and the base 1. Figure 3 and Figure 4As shown, a plurality of hooks 11 are provided on the base 1, and a plurality of holes 22 that cooperate with the plurality of hooks 11 are provided on the cover plate 2. By providing the hooks 11 on one side of the base 1 facing the cover plate 2 and providing the holes 22 that cooperate with the hooks 11 on the cover plate 2, it can be ensured that the surface of the base 1 facing away from the cover plate 2 is a flat surface and does not have a protruding structure, facilitating the surface of the base 1 facing away from the cover plate 2 to fit with the fixing member 7. In addition, the cooperation of the plurality of hooks 11 and the plurality of holes 22 can improve the connection reliability between the base 1 and the cover plate 2.

[0046] Furthermore, as Figure 3 and Figure 4 shown, the hooks 11 are a plurality of hooks arranged at intervals along the circumferential direction of the through hole 13 on the base 1, the holes 22 are a plurality of holes arranged at intervals along the floating hole 21 on the cover plate 2, and the plurality of hooks 11 correspond to the plurality of holes 22 one by one. Thus, the connection reliability between the base 1 and the cover plate 2 can be ensured along the circumferential direction of the through hole 13 and the floating hole 21.

[0047] Specifically, as Figure 3 shown, the hook 11 includes a connecting portion 111 and a hook portion 112. One end of the connecting portion 111 is connected to the base 1, the other end of the connecting portion 111 extends towards the cover plate 2, one end of the hook portion 112 is connected to the other end of the connecting portion 111, the hook portion 112 and the connecting portion 111 form an angle with each other, and the hook portion 112 is adapted to pass through the hole 22 and abut against the surface of the cover plate 2 facing away from the base 1, thereby realizing the connection between the base 1 and the cover plate 2.

[0048] Furthermore, a guiding inclined surface 113 is provided on the hook portion 112, and the guiding inclined surface 113 is provided on the side of the hook portion 112 facing away from the connecting portion 111. The guiding inclined surface 113 on the hook portion 112 facilitates passing the hook portion 112 through the hole 22 on the cover plate 2.

[0049] In some embodiments of the present utility model, as Figure 1 and Figure 3 shown, limiting plates 12 are provided on both sides in the width direction of the surface of the base 1 facing the cover plate 2, and the limiting plates 12 extend along the length direction of the base 1, so that the base 1 as a whole has a concave-shaped structure, and the middle part of the base 1 serves as a reference plane to keep the nut member 3 in contact with the base 1 and the cover plate 2 before and after floating and tightening. The length of the fixing plate 31 along the length direction of the base 1 is greater than the distance between the two limiting plates 12, which can prevent the nut member 3 from rotating too much when the fastening bolt 8 enters the nut portion 32 of the nut member 3 for assembly and tightening, facilitating the connection between the fastening bolt 8 and the nut member 3, and thus facilitating the connection between the member to be fixed 9 and the fixing member 7.

[0050] For example, as Figure 2 、 Figure 3 and Figure 5In the illustrated example, the fixing plate 31 is a rectangle extending along the length direction of the base 1. The long side of the fixing plate 31 is in the same direction as the limiting plate 12 of the base 1. The width of the fixing member 7 is smaller than the distance between the two limiting plates 12. When the fastening bolt 8 and the nut member 3 are connected, the limiting plate 12 can limit the rotation angle of the fixing plate 31, facilitating the connection between the fastening bolt 8 and the nut member 3.

[0051] In some embodiments of the present utility model, such as Figure 4 shown, the floating hole 21 is an oblong hole extending along the length direction of the cover plate 2. The inner peripheral wall of the floating hole 21 can better fit with the outer peripheral wall of the nut portion 32, enabling the nut portion 32 of the nut member 3 to move within the floating hole 21 of the cover plate 2, and maximizing the utilization of the movement space in the direction perpendicular to the axis of the floating hole 21. The free movement space of the nut member 3 can provide tolerance floating adjustment.

[0052] In some embodiments of the present utility model, such as Figure 3 shown, the through hole 13 is an oblong hole extending along the length direction of the base 1. The fastening bolt 8 enters the nut member 3 of the adjustable nut 100 through this, and the inner peripheral wall of the through hole 13 fits with the outer peripheral wall of the fastening bolt 8, enabling the fastening bolt 8 to move within the through hole 13 of the base 1, and maximizing the utilization of the movement space in the direction perpendicular to the axis of the through hole 13. The movement space of the fastening bolt 8 within the through hole 13 can provide the assembly tolerance dimensions to meet the requirements.

[0053] In some embodiments of the present utility model, the inner peripheral walls of the floating hole 21 and the through hole 13 are flush or in the projection on a plane parallel to the base 1, and at least part of the projection of the outer contour of the floating hole 21 overlaps with the projection of the outer contour of the through hole 13. It can be understood that the sizes of the floating hole 21 and the through hole 13 can be the same, or the size of the floating hole 21 can be smaller than the size of the through hole 13, so that the floating range of the nut member 3 is not affected by the movement space of the fastening bolt 8 within the through hole 13, ensuring better floating of the nut member 3 within the floating hole 21 and better adaptability.

[0054] In some embodiments of the present utility model, such as Figure 4 and Figure 5 shown, the outer contour of the nut portion 32 is cylindrical, which can make the outer contour of the nut portion 32 of the nut member 3 fit with each position of the inner peripheral wall of the floating hole 21 of the cover plate 2, maximizing the utilization of the movement space of the nut portion 32 of the nut member 3 on the floating hole 21 of the cover plate 2.

[0055] In some embodiments of the present utility model, such as Figure 5As shown, the nut member 3 further includes a sealing portion 33. The sealing portion 33 is provided at the axial end of the nut portion 32 facing away from the fixing plate 31 and is used to seal the open end at the axial end of the nut portion 32. The sealing portion 33 functions as a seal, which can prevent water from seeping into the nut member 3 from the outside of the nut portion 32, effectively reducing the corrosion of the threads in the nut member 3, and can also prevent external water from entering the surfaces of the fixing member 7 and the member to be fixed 9 through the space between the nut portion 32 and the fastening bolt 8, avoiding corrosion of the fixing member 7 and the member to be fixed 9, etc.

[0056] In some embodiments of the present utility model, such as Figure 5 and Figure 6 As shown, along the axial direction of the nut portion 32, the nut portion 32 includes: a first section 321 and a second section 322. Along the axial direction of the nut portion 32, the inner diameter of the first section 321 remains unchanged, and internal threads are provided on the inner peripheral wall of the first section 321, which is convenient for the external threads on the fastening bolt 8 to cooperate, realizing the connection between the nut member 3 and the fastening bolt 8. In the direction from the first section 321 to the second section 322, the inner diameter of the second section 322 gradually increases, and the second section 322 is in a flared shape, which can play a guiding role, facilitating the fastening bolt 8 to enter the first section 321 and cooperate with the first section 321 for connection. When the fastening bolt 8 is assembled, it can avoid damage to the nut member 3 or other components caused by the introduction direction not completely along the axis direction of the through hole 13 when entering the first section 321. The fixing plate 31 is sleeved outside the second section 322 and is connected to the end of the second section 322 facing away from the first section 321, making the connection between the fixing plate 31 and the nut portion 32 firm and reliable.

[0057] In some embodiments of the present utility model, such as Figure 1 and Figure 3 As shown, the base 1 has a through hole 14. The adjustable nut 100 further includes: a blind rivet 4. The blind rivet 4 is inserted into the through hole 14 and has an interference fit with the through hole 14, which is used to connect the base 1 and the fixing member 7. In addition, the blind rivet 4 has a high tensile strength and the blind rivet 4 can be directly fixed on the object to be connected without machining threads at the hole positions on the object to be connected, saving time and labor costs, and is suitable for the utility model of this application.

[0058] In addition, the through holes 14 are multiple and spaced apart. At least the two ends in the length direction of the base 1 are provided with through holes 14. The blind rivets 4 are multiple and correspond to the multiple through holes 14 one by one, ensuring the firm and reliable connection between the base 1 and the fixing member 7. In addition, the riveting direction of the blind rivet 4 can be determined according to the specific assembly position situation, and can be set as upward riveting or downward riveting. For example, as Figure 1 and Figure 7 As shown, the riveting direction of the blind rivet 4 is upward riveting, or according to the assembly needs, its direction can be inverted and a split structure can be adopted for downward riveting.

[0059] In some embodiments of the utility model, the adjustable nut 100 further includes a first sealing gasket 5, which is disposed on the side of the base 1 away from the cover plate 2. After the adjustable nut 100 is connected, the first sealing gasket 5 is located between the fixing member 7 and the base 1, which can achieve sealing between the fixing member 7 and the base 1, prevent water from penetrating into the gap between the fixing member 7 and the base 1, and reduce the risk of component corrosion. In addition, if Figure 8 and Figure 10 As shown, the first sealing gasket 5 is provided with a first opening 51 opposite to the through hole 13, and the first opening 51 is the same size as or larger than the through hole 13. The fastening bolt 8 can enter the through hole 13 through the first opening 51 and be assembled into the nut member 3 of the adjustable nut 100, and the size of the first opening 51 can be prevented from affecting the movement of the fastening bolt 8, thereby ensuring the movement space of the fastening bolt 8 in the through hole 13, better matching the floating range of the nut member 3, and ensuring that the assembly tolerance size that meets the requirements can be provided.

[0060] Moreover, if Figure 8 As shown, the first gasket 5 has a plurality of assembly holes, at least at both ends of the length direction of the first gasket 5, and the positions of the plurality of assembly holes on the first gasket 5 correspond to the positions of the plurality of through holes 14 on the base 1, so that the plurality of assembly holes are concentrically arranged with the plurality of through holes 14. In addition, the assembly holes are the same size as or larger than the through holes 14, so that the plurality of blind rivets 4 can be inserted into the through holes 14 on the base 1 and the assembly holes on the first gasket 5. Figure 10 As shown, the blind rivet 4 is passed through the through hole 14 on the base 1 and the assembly hole on the first sealing gasket 5, and passes through the fixing piece 7, ensuring that the base 1, the first sealing gasket 5 and the fixing piece 7 are connected and fastened reliably.

[0061] Optionally, the first sealing gasket 5 is made of EPDM (Ethylene-Propylene-Diene Monomer) material, which has sealing and waterproofing functions. Of course, the first sealing gasket 5 can also be made of other materials with the same or similar properties.

[0062] The utility model of the present application has good sealing and waterproof performance, and does not require the design of a waterproof box or cover, etc. It can effectively reduce the redundant sheet metal sealing design caused by sealing reasons, and can also reduce the occupied space. It can reduce material costs, improve assembly efficiency, and greatly expand the applicable scenarios.

[0063] In some embodiments of the present invention, the first sealing gasket 5 is adhered to the base 1 or is integrally injection molded with the base 1, so that the first sealing gasket 5 is firmly and reliably connected to the base 1, ensuring the sealing and waterproof performance between the base 1 and the fixing member 7.

[0064] In some embodiments of the present utility model, the adjustable nut 100 further includes a second gasket 6. The second gasket 6 is disposed on the side of the fixed plate 31 close to the base 1. After the adjustable nut 100 is connected, the second gasket 6 is located between the base 1 and the fixed plate 31, which can achieve the sealing between the base 1 and the fixed plate 31, prevent water from seeping into the gap between the base 1 and the fixed plate 31, and reduce the risk of component corrosion. In addition, as Figure 9 and Figure 10 shown, the second gasket 6 is provided with a second opening 61 opposite to the through hole 13, and the second opening 61 has the same size as or is larger than the second section 322. This enables the fastening bolt 8 to enter the through hole 13 from the first opening 51 and then be assembled into the nut member 3 of the adjustable nut 100 through the second opening 61, and can prevent the size of the second opening 61 from affecting the movement of the fastening bolt 8, thereby ensuring the movement space of the fastening bolt 8 in the floating hole 21, better matching the floating range of the nut member 3, and ensuring that the assembly tolerance dimensions that meet the requirements can be provided.

[0065] Optionally, the second gasket 6 is made of EPDM (Ethylene-Propylene-Diene Monomer), which has the functions of sealing and waterproofing. Of course, the second gasket 6 can also be made of other materials with the same or similar properties.

[0066] In some embodiments of the present utility model, the second gasket 6 is pasted on the fixed plate 31 or integrally injection-molded with the fixed plate 31, making the connection between the second gasket 6 and the fixed plate 31 firm and reliable, and ensuring the sealing and waterproof performance of the position of the fixed plate 31.
