Description

Technical Field

[0001] This utility model relates to the field of bathroom components and products, specifically to an adapter and a flip-up toilet grab bar and a flip-up folding seat made therefrom. Background Technology

[0002] Existing flip-up toilet grab bars and flip-up folding seats rely on an adapter to be fixedly connected to the wall. The adapter includes a back panel with hinge ears on both sides for mounting the hinge base. The hinge base has a socket for inserting the flip-up component. During assembly, the fixing screw passes through the hinge ears, the hinge base, and the flip-up component, which achieves both the hinge engagement between the hinge ears and the hinge base and the pin engagement between the flip-up component and the socket. However, when the hinge base rotates, the flip-up component will rub against the fixing screw, which can easily cause wear between the two and lead to pin engagement. At the same time, this rubbing will also provide a certain circumferential torsional force to the fixing screw during the rotation of the flip-up component, which can easily cause the fixing screw to loosen. Utility Model Content

[0003] Based on the above problems, the purpose of this utility model is to provide an adapter that can reduce or avoid wear and engagement of fixing screws and prevent the fixing screws from loosening during the flipping process, as well as a flip-up toilet grab bar and a flip-up folding seat made therefrom.

[0004] To address the above problems, the following technical solution is provided: an adapter base, including a back plate, with forward-extending hinge ears on both sides of the back plate, each hinge ear having a fixing hole; a hinge base is provided between the two hinge ears, the hinge base having a hinge hole coaxial with and communicating with the hinge ear, and a radial insertion hole for inserting a flip-up component at the midpoint of the hinge base's length direction, the flip-up component having a master pin hole corresponding to the hinge hole, a reinforcing sleeve being provided inside the hinge hole, the reinforcing sleeve being pinned to the master pin hole to fix the flip-up component on the hinge base; further comprising a fixing screw passing through the two hinge ears and the reinforcing sleeve, allowing the hinge base to rotate with the hinge ears.

[0005] The present invention is further configured such that the fixing screws, through axial tightening, bring the end faces of both ends of the hinge seat into close contact with the surface of the hinge ear, thereby providing damping force for the rotation of the hinge seat.

[0006] The present invention is further configured such that countersunk holes are provided at both ends of the hinge hole, and a bearing is provided in the countersunk hole, wherein the inner ring of the bearing is adapted to support the reinforcing sleeve and / or the fixing screw.

[0007] The present invention is further configured such that the hinge seat is provided with a pre-installation hole offset from the hinge hole; the flipping member is provided with a secondary pin hole corresponding to the pre-installation hole; the pre-installation hole and the secondary pin hole are connected by a positioning pin.

[0008] The present invention is further configured such that the flipping component includes an inner tube and a decorative sleeve located outside the inner tube; both the inner tube and the reinforcing sleeve are made of metal.

[0009] The present invention is further configured such that the hinge seat is covered with a decorative cylinder, and the wall of the decorative cylinder is provided with an opening corresponding to the insertion hole for the flipping component to pass through.

[0010] A flip-up toilet grab bar, wherein the flip-up component extends horizontally and its extended end has a vertical section that folds downward, and the lower end of the vertical section has a horizontal support section that extends toward the back panel and abuts against the back panel.

[0011] The present invention is further configured such that the horizontal support section is provided with a hinge joint, the hinge joint is hinged to a vertical support section extending downward and abutting the ground, and the lower end of the vertical support section is hinged to the hinge joint and flipped backward and upward to be close to and parallel to the horizontal support section.

[0012] The present invention is further configured such that the hinge joint rotates relative to the axis of the horizontal support section and / or the vertical section, the horizontal support section, the hinge joint, and the vertical support section rotate along the axis of the flipping component.

[0013] A folding seat includes two sets of interchange seats spaced apart from each other. The flipping parts of each interchange seat extend horizontally outward and their ends are connected by a crossbar. A support plate is provided between the two flipping parts. An oblique support rod that can rotate along the axial direction of the crossbar is hinged to the middle section of the crossbar.

[0014] The beneficial effects of this utility model are: 1. By setting a reinforcing sleeve between the hinge hole and the fixing screw, the flip-up part and the hinge seat are first fixed together by pinning the reinforcing sleeve during the assembly process. Then, it is inserted between the hinge ears and installed by hinge with the fixing screw. This achieves pre-fixation and also allows the reinforcing sleeve to bear the stress between the flip-up part and the hinge seat. This avoids the problem of wear and poor anti-loosening caused by the fixing screw bearing the stress directly, which is caused by the pin and hinge. This effectively improves the assembly efficiency, extends the service life and improves the load-bearing capacity. 2. By utilizing the tight contact between the end faces of the hinge seat and the surface of the hinge ear to provide damping force, the damping torque can be avoided from being applied to the fixing screw, which could cause it to loosen. 3. The fixing screws include bolts and nuts. Due to the need for a concealed design, the nut part will be inserted into the hinge hole. The bearing can isolate the friction between the nut and the hinge seat. The bearing on the other side is located between the reinforcing sleeve and the countersunk hole. It can automatically adapt to the rotational friction between the bolt and the reinforcing sleeve and the rotational friction between the reinforcing sleeve and the hinge hole (based on the lower friction) to further reduce the friction. 4. The spacing between the main pin hole and the auxiliary pin hole on the flip-up part is not equidistant from the spacing between the hinge hole and the pre-installation hole. This creates an interference fit when the reinforcing sleeve and the positioning pin are installed, resulting in a tight fit between the reinforcing sleeve and the positioning pin after installation. This also avoids excess material between the flip-up part and the insertion hole. Attached Figure Description

Detailed Implementation

[0027] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0028] Example 1 refer to Figures 1 to 11 ,like Figures 1 to 5 The adapter shown includes a back plate 10, with hinge ears 11 extending forward on both sides of the back plate 10. Each hinge ear 11 has a fixing hole 111. A hinge seat 20 is provided between the two hinge ears 11. The hinge seat 20 has a hinge hole 21 that is coaxial with and through the hinge ear 11. The middle section of the hinge seat 20 in the length direction has a radial insertion hole 22 for inserting a flip-up component 30. The flip-up component 30 has a master pin hole 31 corresponding to the hinge hole 21. A reinforcing sleeve 40 is provided inside the hinge hole 21. The reinforcing sleeve 40 is pinned to the master pin hole 31 to fix the flip-up component 30 on the hinge seat 20. The adapter also includes a fixing screw 50 that passes through the two hinge ears 11 and the reinforcing sleeve 40 to allow the hinge seat 20 to rotate with the hinge ears 11.

[0029] In the above structure, by setting a reinforcing sleeve 40 between the hinge hole 21 and the fixing screw 50, the flip-up part 30 and the hinge seat 20 are first pin-fixed together using the reinforcing sleeve 40 during the assembly process. Then, it is inserted between the hinge ears 11 and hinged by the fixing screw 50. This achieves pre-fixation while also allowing the reinforcing sleeve 40 to bear the stress between the flip-up part 30 and the hinge seat 20. This avoids the problem of the fixing screw 50 bearing the stress directly, which would cause it to bear the wear and poor anti-loosening properties caused by the pin connection and hinge connection. This effectively improves assembly efficiency, extends service life, and enhances load-bearing capacity.

[0030] In this embodiment, the fixing screw 50 axially tightens the two end faces of the hinge seat 20 into close contact with the surface of the hinge ear 11, providing damping force for the rotation of the hinge seat 20.

[0031] In the above structure, the damping force is provided by the close contact between the end faces of the hinge seat 20 and the surface of the hinge ear 11, which can prevent the damping torque from being applied to the fixing screw 50 and causing it to loosen.

[0032] In this embodiment, the hinge hole 21 has countersunk holes 211 at both ends, which are coaxially arranged with the hinge hole 21. The countersunk hole 211 is provided with a bearing 60, and the inner ring of the bearing 60 is adapted to support the reinforcing sleeve 40 and / or the fixing screw 50.

[0033] In the above structure, the fixing screw 50 includes a bolt 51 and a nut 52. Due to the need for a concealed design, the nut 52 part will enter the hinge hole 21. The bearing 60 can isolate the friction between the nut 52 and the hinge seat 20. The bearing 60 on the other side is located between the reinforcing sleeve 40 and the countersunk hole 211. It can automatically adapt to the rotational friction between the bolt 51 and the reinforcing sleeve 40 and the rotational friction between the reinforcing sleeve 40 and the hinge hole 21 (based on the smaller friction) to further reduce the friction.

[0034] In this embodiment, the hinge seat 20 is also provided with a pre-installation hole 23 offset from the hinge hole 21; the flipping member 30 is provided with a secondary pin hole 32 corresponding to the pre-installation hole 23; the pre-installation hole 23 and the secondary pin hole 32 are connected by a positioning pin 70.

[0035] In the above structure, the spacing between the main pin hole 31 and the auxiliary pin hole 32 on the flipping part 30 is not equidistant from the spacing between the hinge hole 21 and the pre-installation hole 23. This results in an interference fit when the reinforcing sleeve 40 and the positioning pin 70 are installed, so that the reinforcing sleeve 40 and the positioning pin 70 are in a tight fit state after installation. This also avoids the frame between the flipping part 30 and the insertion hole 22.

[0036] In this embodiment, the flipping component 30 includes an inner tube 301 and a decorative sleeve 302 located outside the inner tube 301; both the inner tube 301 and the reinforcing sleeve 40 are made of metal.

[0037] In the above structure, the decorative sleeve 302 is made of plastic.

[0038] In this embodiment, the hinge seat 20 is covered with a decorative tube 80, and the tube wall of the decorative tube 80 is provided with an opening 81 corresponding to the insertion hole 22 for the flipping member 30 to pass through.

[0039] In the above structure, the decorative tube 80 is made of metal.

[0040] Example 2 refer to Figures 1 to 11 ,like Figures 1 to 9The above-flipping toilet grab bar includes the adapter seat in embodiment 1. The flipping member 30 extends horizontally and its extended end is provided with a vertical section 33 that folds downward. The lower end of the vertical section 33 is provided with a horizontal support section 34 that extends towards the back panel 10 and abuts against the back panel 10.

[0041] In the above structure, the flipping component 30 can be positioned by the horizontal support section 34 abutting against the back plate 10 when it is flipped down to the horizontally extended state.

[0042] In this embodiment, the horizontal support section 34 is provided with a hinge joint 341, and the hinge joint 341 is hinged to a vertical support section 35 that extends downward and abuts against the ground. The lower end of the vertical support section 35 is hinged to the hinge joint 341 and flipped backward and upward to be close to and parallel to the horizontal support section 34.

[0043] In the above structure, the vertical support force is improved by the vertical support section 35, and support pads 90 are provided at the ends of both the vertical section 33 and the vertical support section 35.

[0044] In this embodiment, the hinge joint 341 rotates relative to the axis of the horizontal support section 34 and / or the vertical section 33, the horizontal support section 34, the hinge joint 341, and the vertical support section 35 rotate along the axis of the flipping member 30.

[0045] The above structure can further reduce the storage volume.

[0046] Example 3 refer to Figures 1 to 11 ,like Figures 1 to 5 , Figure 10 , Figure 11 The illustrated folding seat includes two sets of interchange seats spaced apart from each other, as shown in Embodiment 1. The flipping parts 30 of each interchange seat extend horizontally outward and their ends are connected by a crossbar 36. A support plate 37 is provided between the two flipping parts 30. An oblique support rod 38 that can rotate along the axial direction of the crossbar 36 is hinged to the middle section of the crossbar 36.

[0047] In the above structure, the end 38 of the inclined support rod is used to support the angle between the wall and the ground, providing support for the flipping part 30 in a horizontal state.

[0048] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
