Abstract
Description
Technical Field
[0001] This utility model relates to the field of shower auxiliary facilities technology, specifically to a folding shower chair with a self-locking joint that flips up. Background Technology
[0002] With the increasing aging population, more and more elderly people are experiencing joint and musculoskeletal degeneration. Standing for long periods while showering, squatting, and standing up become difficult due to the lack of strength. As a result, more and more elderly people need shower chairs. Foldable shower chairs can solve the bathroom needs of the elderly while saving storage space. The folding joint is a key component of foldable shower chairs. Most upward-folding joints on the market use a spring structure, which is expensive and prone to failure after repeated use due to reduced spring strength, potentially leading to falls and injuries. Utility Model Content
[0003] This utility model provides a folding shower chair with a self-locking joint for flipping up, which solves the problems of high cost and easy failure after repeated use of the spring structure in the existing technology.
[0004] The technical solution adopted by this utility model to solve its technical problem is:
[0005] A folding shower chair with a self-locking hinge is composed of a fixed joint, a rotating joint, and a fixing component. One end of the fixed joint has a limiting groove, and a pivot hole is provided on one side of the limiting groove. The other end of the fixed joint has a snap-fit groove. The rotating joint has a waist hole corresponding to the pivot hole of the fixed joint. The waist hole has a certain tilt angle corresponding to the rotating joint. One end of the rotating joint is inserted into the limiting groove of the fixed joint. The fixing component passes through the pivot hole and the waist hole to fix the fixed joint and the rotating joint. The other end of the rotating joint has a connector.
[0006] The aforementioned fasteners are screws, fixed shafts, or other types of fasteners.
[0007] The working principle of the self-locking joint of this folding shower chair is as follows: When the product needs to be folded, the rotating joint rotates upward 90 degrees around the pivot hole. Due to the presence of the waist hole in the rotating joint, the joint sinks under the influence of gravity. The waist hole and the rotating joint are not parallel and have a certain tilt angle. The lower the rotating joint sinks, the smaller the gap between it and the fixed joint, thus achieving self-locking. Conversely, lifting the rotating joint and then flipping it downward opens the joint.
[0008] This invention can be used on folding shower chairs. By combining fixed joints and rotating joints with waist holes at a certain angle, the joint gravity self-sinking locking function is realized. It has the advantages of simple structure, low cost and safety and reliability. Attached Figure Description

[0016] In the figure, 1 is the fixed joint, 2 is the rotating joint, 3 is the fastener, 11 is the limiting groove, 12 is the snap-fit groove, 13 is the pivot hole, 21 is the waist hole, and 22 is the connector. Detailed Implementation
[0017] like Figure 1 , Figure 2 and Figure 3 As shown, a folding shower chair with a self-locking hinge is composed of a fixed joint 1, a rotating joint 2, and a fixing member 3. One end of the fixed joint 1 has a limiting groove 11, and a pivot hole 13 is provided on one side of the limiting groove 11. The other end of the fixed joint 1 has a snap-fit groove 12. The rotating joint 2 has a waist hole 21 corresponding to the pivot hole 13 of the fixed joint 1, and the waist hole 21 has a certain tilt angle relative to the rotating joint 2. One end of the rotating joint 2 is inserted into the limiting groove 11 of the fixed joint 1. The fixing member 3 passes through the pivot hole 13 and the waist hole 21 to fix the fixed joint 1 and the rotating joint 2. The other end of the rotating joint 2 has a connector 22. The fixing member 3 is a screw, a fixing shaft, or other type of fixing member.
[0018] The working principle of the self-locking joint of this folding shower chair is as follows: Figure 3 and Figure 4 As shown, when the product needs to be folded, joint 2 rotates upwards by 90 degrees around the pivot hole 13; as shown... Figure 5 and Figure 6 As shown, due to the presence of the waist hole 21, the rotary joint 2 sinks under the influence of gravity, and the rotary joint 2 fits into the limiting groove 11 of the fixed joint 1. The waist hole 21 of the rotary joint is not parallel to the rotary joint 2 and has a certain tilt angle. As the rotary joint 2 sinks further, the gap between it and the fixed joint 1 becomes smaller, thus achieving self-locking. Conversely, lifting the rotary joint 2 and then flipping it downwards will open the joint.
