Description

Technical Field

[0001] The utility model relates to a metal pipe toilet handrail hinge end bearing torsion joint component. Background Art

[0002] Toilet grab rails are bathroom grab rails installed on both sides of the toilet or squat toilet. When the user is using the toilet, he can use the toilet grab rails to gain leverage to get up.

[0003] The toilet handrail in the related art includes a handrail installed on fixed seats on both sides of the toilet, and the pipe end of the handrail is fixedly connected to a hinged seat hinged on the fixed seat so that the handrail can be rotated and switched between a use state and a storage state.

[0004] The above-mentioned toilet armrests have the following problems when in use: 1. The toilet armrest pipe end and the hinged seat are often fixed and connected by welding. Manual operation may cause a "cold weld" between the two, resulting in poor fixing strength of the armrest and reduced product reliability; 2. As the toilet armrest is used for a long time, the connection end between the pipe end and the hinged seat is prone to falling off and cracking, causing the protective function of the toilet armrest to fail and posing a safety hazard. Utility Model Content

[0005] The utility model provides a metal pipe toilet handrail hinge end bearing torsion joint assembly, which can effectively solve the above problem.

[0006] The utility model is achieved in this way:

[0007] A metal pipe toilet handrail hinge end bearing torsion joint assembly, comprising a swing arm seat rotatably matched with fixed seats on both sides of the toilet, the swing arm seat comprising a base portion, a plug-in sleeve protruding from the upper end surface of the base portion, and a limit portion extending upward from one side of the base portion;

[0008] The plug-in tube is plugged into the tube end of the armrest swing arm, and a limit pin is arranged on the fixed seat near the limit part. When the armrest is flipped from the storage state to the use state, the limit part abuts against the side of the limit pin to lock the armrest in the use state.

[0009] As a further improvement, the limiting portion has an arc-shaped groove facing the plug-in tube side and covering the side wall of the armrest swing arm tube end.

[0010] As a further improvement, an internal hole connected to the interior is formed through the side wall of the plug-in tube, an external hole is formed through the side wall of the armrest swing arm tube end, and a rotating pin shaft inserted into the external hole and the internal hole is mounted on the fixed seat. The swing arm seat uses the rotating pin shaft as the rotation axis to drive the swing arm of the armrest to rotate and cooperate with the fixed seat.

[0011] As a further improvement, when the plug-in tube is inserted into the tube end of the armrest swing arm and the tube end is pressed against the upper end surface of the base portion, the inner hole and the outer hole are coaxially opposite to each other.

[0012] As a further improvement, the plug-in tube is provided with a plurality of shell extraction grooves in a circular array toward the limiting portion.

[0013] As a further improvement, the handrail includes a swing arm tube and a handrail tube bent at the end of the swing arm tube for leaning against, and the line connecting the axis of the revolving pin shaft and the limit pin shaft is parallel to the bottom plate of the fixed seat.

[0014] As a further improvement, the armrest includes a swing arm tube, and a line connecting the axes of the revolving pin and the limiting pin forms an angle of 15° with the bottom plate of the fixed seat.

[0015] The beneficial effects of the utility model are:

[0016] (I) This application solves the problem of possible cold welding of the original welded parts at the pipe ends, improves the strength of the handrail installation, and thus improves the reliability of the product.

[0017] (ii) The present application realizes the installation connection between the swing arm seat and the armrest through a sleeve-and-plug fitting method, thereby improving product assembly efficiency and reducing assembly production costs.

[0018] (III) The present application effectively avoids the problem of the hinged end of the handrail swing arm pipe being loosened, which would cause the protective function of the pipe to fail, thereby greatly improving the safety of the product during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] like Figure 1 to Figure 3 As shown, a metal tube toilet armrest hinge end bearing torsion joint assembly includes a swing arm seat 10 rotatably engaged with the fixed seats 20 on both sides of the toilet, the swing arm seat 10 includes a base portion 11, a plug-in tube 12 protruding from the upper end surface of the base portion 11, and a limit portion 13 extending upward from one side of the base portion 11; the plug-in tube 12 is plugged into the tube end 312 of the swing arm of the armrest 30, and a limit pin 21 is mounted on the fixed seat 20 near the limit portion 13; when the armrest 30 is flipped from the storage state to the use state, the limit portion 13 abuts against the side of the limit pin 21 to lock the armrest 30 in the use state.

[0029] like Figure 2 and Figure 3 As shown, the angle between the extension direction of the limiting portion 13 of the swing arm seat 10 and the axis of the plug-in tube 12 is preferably 15°; the limiting portion 13 is facing the plug-in tube 12 side and is an arc-shaped groove 131 that covers the side wall of the swing arm tube end 312 of the armrest 30. With such a design, when the armrest 30 is in use, the groove wall of the arc-shaped groove 131 can support the side wall of the swing arm tube end 312 of the armrest 30 as a whole, so that the armrest 30 can be stably locked in the use state.

[0030] like Figure 2 and Figure 3 As shown, the side wall of the plug-in tube 12 is penetrated with an inner hole 121 connected to the inside, and the side wall of the swing arm tube end 312 of the handrail 30 is penetrated with an outer hole 311. A rotating pin 22 inserted into the outer hole 311 and the inner hole 121 is mounted on the fixed seat 20. The swing arm seat 10 uses the rotating pin 22 as a rotation axis to drive the swing arm of the handrail 30 to rotate and cooperate with the fixed seat 20; when the plug-in tube 12 is inserted into the tube end 312 of the swing arm of the handrail 30 and the tube end 312 is pressed against the upper end surface of the base portion 11, the inner hole 121 and the outer hole 311 are coaxially opposite. It should be noted here that the limit pin 21 and the rotating pin 22 are both mounted on the opposite side plates 202 of the fixed seat 20 by bolts 23.

[0031] like Figure 3As shown, the plug-in tube 12 is provided with a plurality of shell extraction grooves 122 in a circular array toward the limiting portion 13. Such a design not only facilitates the mold opening of the swing arm seat 10, but also improves the structural strength of the plug-in tube 12, thereby improving the connection strength between the swing arm of the armrest 30 and the swing arm seat 10.

[0032] The present application is divided into two different implementations according to the different structures of the handrail 30 to be installed.

[0033] Embodiment 1: Figure 1 to Figure 3 As shown, the handrail 30 includes a swing arm tube 31 and a handrail tube 32 bent at the end 312 of the swing arm tube for leaning against; when this type of handrail 30 is used, the fixing seat 20 is installed on both sides of the toilet.

[0034] The plug-in tube 12 on the swing arm seat 10 is inserted into the tube end 312 of the swing arm tube 31 of the armrest 30, and the swing arm seat 10 and the armrest 30 are rotated and installed on the fixed seat 20 through the rotating pin shaft 22; when the assembly is completed, the connecting line at the axis of the rotating pin shaft 22 and the limit pin shaft 21 is parallel to the bottom plate 201 of the fixed seat 20.

[0035] The armrest 30 is flipped downward 60° clockwise until the limit portion 13 abuts against the side of the limit pin 21, so that the armrest 30 is locked in a use state for leaning on. When storing, the armrest 30 only needs to be flipped upward 60° counterclockwise to restore the armrest 30 to the storage state that avoids the two sides of the toilet.

[0036] Embodiment 2: Figure 4 and Figure 5 As shown, the handrail 30 includes a swing arm tube 31; when this type of handrail 30 is used, the fixing seat 20 is installed on both sides of the wall behind the toilet.

[0037] The plug-in tube 12 on the swing arm seat 10 is inserted into the tube end 312 of the swing arm tube 31, and the swing arm seat 10 and the armrest 30 are rotated and installed on the fixed seat 20 by rotating the pin shaft 22; when the assembly is completed, a 15° angle is formed between the line connecting the axis of the rotating pin shaft 22 and the limit pin shaft 21 and the bottom plate 201 of the fixed seat 20.

[0038] The armrest 30 is flipped downward 90° clockwise until the limit portion 13 abuts against the side of the limit pin 21, so that the armrest 30 is locked in a use state for leaning on. At this time, the swing arm tube 31 is in a horizontal state and parallel to the ground; when storing, the armrest 30 only needs to be flipped upward 90° counterclockwise to restore the armrest 30 to the storage state that avoids the two sides of the toilet. At this time, the swing arm tube 31 is parallel to the wall (perpendicular to the ground).

[0039] The above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. A person skilled in the art may make various modifications or changes without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention and be defined by the claims.
