Description

Technical Field

[0001] This application relates to the field of irregular screws, and in particular to a bracket fixing shaft screw. Background Technology

[0002] Hanger fixing screws are an indispensable fastening component in home installation projects. They are commonly found in household appliances. Their main purpose is to ensure that the hanger fixing screws and the supporting structure, such as the wall, bracket, and the appliance itself, form a reliable connection to achieve stable load-bearing and safe fixation.

[0003] In related technologies, traditional bracket fixing screws are mainly used to ensure that the bracket fixing screws and the supporting structure form a reliable connection.

[0004] However, traditional bracket fixing screws have the following drawbacks: traditional bracket fixing screws adopt a one-piece molding design. For screws with special shape requirements, i.e. irregular screws, the overall structure is more complicated to process, the processing difficulty is high, and the production cost is high. Utility Model Content

[0005] To reduce the difficulty of machining irregularly shaped screws, this application provides a bracket fixing shaft screw.

[0006] The technical solution for a bracket fixing shaft screw provided in this application is as follows:

[0007] A mounting bracket fixing shaft screw includes a first component and a second component. The first component includes a first base, and the second component includes a second base. The first base and the second base are riveted together to form an annular groove that mates with the movable slots of electronic components inside household appliances.

[0008] By adopting the above technical solutions, traditional one-time molding molds need to meet the high-precision fit of the head and the threaded rod at the same time, which is complex and expensive. The split riveting structure, by dividing the bracket fixing shaft screw into two parts, the first component and the second component, and riveting them together, significantly reduces the overall processing complexity and production cost. In household appliances and electronic components, the annular groove can support the rotation, sliding and angle adjustment of the components installed on the bracket fixing shaft screw.

[0009] Preferably, the first component further includes a first fixing member, which is perpendicularly fixed to the first base. The second component further includes a second fixing member, which is perpendicularly fixed to the second base. The second fixing member is sleeved on the outside of the first fixing member and riveted to the first fixing member.

[0010] By adopting the above technical solution, the first fixing member and the first base, as well as the second fixing member and the second base, are all vertically fixed to form a three-dimensional support structure, which improves the structural strength. The second fixing member is sleeved on the outside of the first fixing member and riveted to form a concentric sleeve structure. The riveting achieves tight contact and reduces loosening or displacement.

[0011] Preferably, the outer wall of the first fastener is provided with straight teeth in the circumferential direction, and when the second fastener is sleeved and riveted with the first fastener, the straight teeth abut against the inner wall of the second fastener.

[0012] By adopting the above technical solution, through the riveting of the first fixing member and the second fixing member, the outer wall of the straight tooth abuts against the inner wall of the second fixing member. The outer wall of the straight tooth is squeezed by the inner wall of the second fixing member, thereby generating a reverse force on the inner wall of the second fixing member, increasing the friction between the second fixing member and the first fixing member, and reducing relative sliding and loosening caused by vibration or impact.

[0013] Preferably, the first component further includes a connector and a threaded rod, the connector being vertically fixed to the end of the first fixing member away from the first base, and both ends of the connector being coaxially fixed to the first fixing member and the threaded rod, respectively.

[0014] By adopting the above technical solution, the coaxial fixed connection between the connector and the threaded rod achieves high-strength rigid support, enhances axial load-bearing capacity, and reduces the risk of thread loosening and failures caused by loosening.

[0015] Preferably, the second base is provided with a mounting hole, which forms a through structure with the interior of the second fixing member. The channel of the mounting hole is directly connected to the interior of the second fixing member, so that the threaded rod can pass through the channel of the mounting hole to the outside.

[0016] By adopting the above technical solution, the mounting hole can be pre-set, and the mounting hole is directly connected to the inside of the second fastener, so that the threaded rod can pass through the second fastener in one go, reducing the need for additional drilling and external connecting parts, and reducing assembly steps.

[0017] Preferably, the end face of the second fixing member away from the second base is in close contact with the surface of the first base to form an abutment fit, thereby achieving the limiting and fixing of the first base and the second base.

[0018] By adopting the above technical solution, the end face of the second fastener away from the second base abuts against the surface of the first base, which can automatically align the positions of the first base and the second base, reducing the reliance on auxiliary components such as bolts and positioning pins in traditional assembly and reducing the complexity of assembly.

[0019] Preferably, the outer edges of the first base and the second base are rounded, covering all the outer edges of the first base and the second base.

[0020] By adopting the above technical solution, the rounded corners reduce the sharpness of the outer edges of the first and second bases, thus reducing the likelihood of scratches and cuts to operators during installation and use. Simultaneously, when a mounting bracket's fixing shaft slides within the movable slots of electronic components inside household appliances, the smooth transition of the rounded corners reduces friction and sliding resistance.

[0021] Preferably, the first base, the first fixing member, the connecting member, and the threaded rod are integrally formed.

[0022] By adopting the above technical solution, the structural strength and stability are improved by integrally molding the first base, the first fixing part, the connecting part and the screw.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. A bracket fixing shaft screw with a split riveting structure significantly saves costs by reducing mold complexity, while the annular groove design supports component rotation, sliding and multi-angle adjustment;

[0025] 2. The second fastener abuts tightly against the inner wall of the straight tooth, significantly increasing the friction, thereby reducing relative sliding and loosening, and improving connection reliability;

[0026] 3. The tight contact between the end face of the second fixing component and the first base enables the positioning of the first base and the second base, reducing the reliance on auxiliary components such as bolts and positioning pins, and reducing assembly complexity.

[0030] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0031] This application discloses a bracket fixing shaft screw. (Refer to...) Figure 1A bracket fixing shaft screw includes a first component, which includes a first base 1, a first fixing member 2, a connecting member 3, and a threaded rod 4. One end of the first fixing member 2 is vertically fixed to the first base 1, the connecting member 3 is vertically fixed to the end of the first fixing member 2 away from the first base 1, the other end of the connecting member 3 is vertically fixed to the first fixing member 2, and both ends of the connecting member 3 are coaxially fixed to the first fixing member 2 and the threaded rod 4, respectively.

[0032] Specifically, in this embodiment, the first base 1 is disc-shaped, and one end of the first fixing member 2 is vertically fixed to the central area of ​​the first base 1. The first fixing member 2 and the connecting member 3 are cylindrical. One end of the connecting member 3 is vertically fixed to the top of the first fixing member 2 away from the base, and the other end is vertically fixed to the threaded rod 4. The threaded rod 4 is a slender cylindrical rod with standard threads machined on its surface. The axis of the threaded rod 4 coincides with the first fixing member 2, the connecting member 3, and the first base 1. It is an integrally formed structure, which ensures that the whole extends vertically and there is no offset between the components, thereby improving the structural strength and stability.

[0033] On the other hand, the second component also includes a second fixing member 6 and a second base 5. The second fixing member 6 is vertically fixed to the second base 5, which is a disc-shaped base. The second fixing member 6 is vertically fixed to the center area of ​​one side surface of the second base 5 and is cylindrical in shape.

[0034] Furthermore, when the first component and the second component are formed into a whole by riveting, the first base 1 and the second base 5 are riveted together, the second fastener 6 is sleeved on the outside of the first fastener 2 and riveted to the first fastener 2, the hole of the mounting hole 51 is directly connected to the inside of the second fastener 6 so that the threaded rod 4 can pass through the opening at one end of the second fastener 6 and pass through the opening at one side of the mounting hole 51 to the outside of the second base 5. The end face of the second fastener 6 away from the second base 5 is in close contact with the surface of the first base 1 to form an abutment fit.

[0035] Specifically, when the first component and the second component are joined by riveting, the first base 1 and the second base 5 are fixed. Both the first base 1 and the second base 5 are disc-shaped, and the first base 1 and the second base 5 have the same size and shape. The first base 1 and the second base 5 are fixed while their edges are aligned and their axes are collinear.

[0036] This shows that traditional one-piece molds need to meet the high-precision fit of the head and the threaded rod 4 at the same time, which is complex and expensive. In contrast, the split riveting structure divides the bracket fixing shaft screw into two parts, the first component and the second component, and rivets them together, which significantly reduces the overall processing complexity and production cost.

[0037] Reference Figure 2In addition, the outer peripheral wall of the first fixing member 2 is provided with straight teeth 8 at intervals in the circumferential direction. The straight teeth 8 are integrally formed with the first fixing member 2. In this embodiment, the straight teeth 8 are formed by lathe cutting. The tooth line of the straight teeth 8 is parallel to the central axis of the first fixing member 2. The second fixing member 6 is set as a hollow tubular structure. The second fixing member 6 is sleeved on the first fixing member 2 and riveted. The straight teeth 8 provided on the outer wall of the first fixing member 2 abut against the inner wall of the second fixing member 6 so that the first fixing member 2 and the second fixing member 6 form an interference fit.

[0038] This explains that the second fixing member 6 is sleeved on the outside of the first fixing member 2 and riveted to form a concentric sleeve structure. The riveting achieves tight contact, reducing loosening or displacement. When the first fixing member 2 and the second fixing member 6 are riveted together, the outer wall of the straight tooth 8 is squeezed by the inner wall of the second fixing member 6, thereby generating a reverse force on the inner wall of the second fixing member 6. This increases the friction between the second fixing member 6 and the first fixing member 2, reducing relative sliding and loosening caused by vibration or impact.

[0039] Furthermore, a through mounting hole 51 is provided at the center of the bottom of the second base 5, and the second fixing member 6 is centrally located. The mounting hole 51 communicates with the interior of the second fixing member 6. The mounting hole 51 is located at the center of the second base 5. The diameter of the mounting hole 51 is the same as the inner diameter of the second fixing member 6, and the axial direction of the mounting hole 51 coincides with the axis of the second fixing member 6, forming a straight channel from the interior of the second fixing member 6 to the exterior of the second base 5.

[0040] Therefore, the mounting hole 51 is precisely machined into a circle and is completely coaxial with the interior of the second fastener 6. The hole diameter matches the interior diameter of the second fastener 6, ensuring that the threaded rod 4 can pass through unobstructed. The mounting hole 51 allows the threaded rod 4 to pass through this channel to the outside, reducing the need for additional drilling and external connectors 3, and reducing assembly steps.

[0041] In addition, the first component and the second component are riveted together. The end face of the second fixing member 6 away from the second base 5 is a flat annular plane. The annular plane is closely fitted with the connecting surface formed by the outer edge of the first base 1 and the outer edge of the first fixing member 2. The contact fit is achieved by radial extrusion during riveting, thereby achieving the limiting and fixing of the first base 1 and the second base 5.

[0042] Therefore, by closely fitting the first base 1 and the second fixing member 6, the reliance on auxiliary components such as bolts and positioning pins in traditional assembly is reduced, thus lowering the complexity of assembly. This not only defines the positional relationship between the first base 1 and the second base 5 in the vertical direction, but also enhances the rigidity and stability of the overall structure.

[0043] On the other hand, since the first fixing member 2 and the second fixing member 6 are both vertically fixed to the first base 1 and the second base 5, and the first base 1 and the second base 5 are both disc-shaped, when the first fixing member 2 and the second fixing member 6 are riveted together, the first base 1 and the second base 5 are connected by the assembly formed by the riveting of the first fixing member 2 and the second fixing member 6, and an annular groove 7 with a continuous inner wall is formed at the joint. The opposite side walls of the first base 1 and the second base 5 and the outer wall of the second fixing member 6 constitute the groove wall of the annular groove 7.

[0044] Correspondingly, in household appliances and electronic components, the annular groove 7 can support the rotation, sliding, and angle adjustment of components mounted on the bracket fixing shaft screw, thereby achieving a stable installation while allowing the components mounted on the bracket fixing shaft screw to rotate or slide freely within the annular groove 7.

[0045] Furthermore, the outer edges of the first base 1 and the second base 5 are rounded at corners 9. Specifically, the rounded corners 9 allow the outer contours of the first base 1 and the second base 5 to smoothly transition from top to bottom along the edge, and the outer edge of each base gradually curves from the straight edge to the edge, forming a continuous arc surface with a consistent radius.

[0046] To further explain, the rounded corner 9 reduces the sharpness of the outer edges of the first base 1 and the second base 5, thus reducing the likelihood of scratches and cuts to operators during installation and use. Simultaneously, when a mounting bracket slides within the movable slots of electronic components inside household appliances, the smooth transition of the rounded corner 9 reduces friction and sliding resistance.

[0047] The implementation principle of a bracket fixing shaft screw in this application embodiment is as follows:

[0048] The bracket fixing shaft screw disclosed in this application adopts a split riveting structure design, which reduces the overall processing complexity and production cost.

[0049] A bracket fixing shaft screw is divided into a first component and a second component. The first component includes a first base, a first fixing member, a connecting member, and a threaded rod. The second component includes a second base and a second fixing member. The first component and the second component are joined together by a press-fitting process.

[0050] The first base is disc-shaped, and the first fixing member is vertically fixed to the first base. The connecting member connects the first fixing member and the threaded rod, forming a vertically extending axial structure. The surface of the threaded rod is machined with standard threads and is integrally formed with all components to ensure that the axes are collinear, thereby improving strength and stability. The second base is a disc-shaped base, and the second fixing member is vertically fixed to the center of the surface of the second base. It is hollow and tubular, and is fitted over the first fixing member and riveted in place.

[0051] Traditional unibody molding requires high-precision molds, while the split design allows each component to be processed individually before riveting, simplifying mold requirements and reducing production costs. Through press riveting, the edges of the first and second bases are aligned and their axes are collinear. Simultaneously, the second fixing component and the first fixing component form a concentric sleeve structure, reducing the risk of loosening or misalignment.

[0052] The outer wall of the first fastener is provided with straight teeth, which are distributed parallel to each other along the axial direction. They are integrally formed by lathe cutting and abut against the inner wall of the second fastener. The second fastener has an internal hollow structure. After the first fastener is fitted, the straight teeth and the inner wall of the second fastener produce an interference fit during the riveting process, which increases the friction and reduces the probability of loosening caused by vibration or impact. In addition, the end face of the second fastener is tightly fitted with the first base, and the contact fit is achieved by radial extrusion, which further restricts vertical displacement and improves overall rigidity.

[0053] The second base has a through mounting hole at the bottom center, which is completely coaxial with the inside of the second fastener, forming a straight channel. The threaded rod can pass directly through this channel to the outside without additional drilling or connecting parts, simplifying the assembly steps and reducing errors. The diameter of the mounting hole matches the inner diameter of the second fastener, ensuring that the threaded rod can pass through without obstruction, thus improving installation accuracy and reliability.

[0054] Furthermore, after the first and second components are joined together by a press-fitting process, the opposite side walls of the first and second bases and the outer wall of the second fixing member form an annular groove. The annular groove allows installed components, such as home appliances and electronic components, to rotate, slide, or adjust their angles freely within the groove, thus balancing the needs for stable installation and flexible adjustment.

[0055] The rounded corners of the first base and the second outer edge reduce edge sharpness, minimizing the risk of scratches to operators, while also reducing resistance during sliding applications and extending service life.

[0056] In summary, a split structure for the mounting bracket fixing shaft screw can reduce mold complexity and production costs. The riveting process simplifies the assembly process, the straight tooth interference fit and riveting fixation enhance the anti-loosening ability and ensure long-term stability. The annular groove supports rotation and sliding functions, adapting to the flexible installation needs of home appliances and other scenarios. The rounded corner design improves operational safety, and the integrated mounting hole reduces assembly steps.

[0057] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
