[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Examples, such as Figures 1-6As shown, this utility model provides a folding shower chair, including a main support tube 1. A backrest 2 is located at the top of the main support tube 1, and armrest assemblies 3 are rotatably connected to both sides of the main support tube 1. A rear support tube 4 is hinged to the bottom of the main support tube 1, and a seat 5 is rotatably connected to the rear support tube 4. The main support tube 1 provides the mounting base for the backrest 2 and armrest assemblies 3. The backrest 2 can rotate adaptively around the top section of the main support tube 1 at a certain angle. The armrest assemblies 3 can be unfolded to a fixed angle with the main support tube 1 and can be folded up. The rear support tube 4 forms a cross-support system with the main support tube 1, and also provides the mounting base for the seat 5, allowing the seat 5 to unfold and fold around the rear support tube 4. Based on this, the main support tube 1 provided by this utility model is provided with a front positioning rod 6 and a rear positioning rod 7 distributed in the front and rear. At least one pair of front locking arm assemblies 8 that cooperate with the front positioning rod 6 are provided below the seat 5. The front locking arm assemblies 8 are used to support the seat 5 in the unfolded state and the folded state. The seat 5 is provided with a rear locking arm assembly 9 that cooperates with the rear positioning rod 7 near its rear side. The rear locking arm assembly 9 is used to support the seat 5 in the unfolded state.

[0027] Specifically, in the unfolded state, the front locking arm assembly 8 can engage with the front positioning rod 6, and the rear locking arm assembly 9 can engage with the rear positioning rod 7. This front and rear engagement establishes a relatively stable support relationship, improving the stability of the seat 5 under stress conditions and ensuring the stability of the device in the unfolded state, thus enhancing the showering and bathing experience. Furthermore, in the folded state, the front locking arm assembly 8 and the front positioning rod 6 work together to achieve stable positioning, preventing the device from unfolding arbitrarily and thus avoiding accidental injury to the user's legs or feet.

[0028] like Figure 2 , Figure 4 and Figure 6 As shown, the front arm assembly 8 provided by this utility model includes a front plate 81 connected to the bottom surface of the seat 5. A fixed hinge 82 is provided at one end of the front plate 81, and a hinge shaft 83 is provided at the rotation center of the fixed hinge 82. A forearm 84 is provided on the hinge shaft 83, and a latch 85 is provided at the end of the forearm 84 away from the hinge shaft 83. The latch 85 cooperates with the front positioning rod 6. Screw holes are provided on the front plate 81, and the front plate 81 is fixed to the seat 5 by screws, providing a stable rotation base for the fixed hinge 82 and the forearm 84. The forearm 84 can be rotated around the hinge shaft 83. By rotating, the latch 85 can be established and contacted with the front positioning rod 6. Furthermore, the forearm 84 adopts a reinforced box girder arm, so it not only has good support performance, but also high structural strength, and its actual service life is relatively long.

[0029] To improve the rotational fit between the seat 5 and the rear support tube 4, this utility model provides a shaft tube 86 on the front plate 81 that fits with the end of the rear support tube 4. The hollow part of the shaft tube 86 can fit with the end of the rear support tube 4. The shaft tube 86, together with the front plate 81, maintains a relatively stationary relationship with the seat 5. Therefore, by flipping the seat 5, the front arm assembly 8 and the rear support tube 4 can be rotated relative to each other, thereby achieving reasonable folding.

[0030] To improve the practicality of the rear arm assembly 9, the rear arm assembly 9 provided by this utility model includes a rear plate 91 connected to the bottom surface of the seat 5. A multi-segment rear arm 92 is provided on the rear plate 91. The multi-segment rear arm 92 is rotatably engaged with the rear plate 91 and has a bend 93 that engages with the rear positioning rod 7. The rear plate 91 serves as the mounting base for the multi-segment rear arm 92, which can perform a certain flipping motion on the rear plate 91 to establish a locking relationship with the unfolded rear positioning rod 7.

[0031] Specifically, the multi-segment rear arm 92 provided by this utility model includes a first U-shaped segment 921 and a second U-shaped segment 922. The bend 93 is formed by bending the first U-shaped segment 921. The connection end between the first U-shaped segment 921 and the second U-shaped segment 922 is rounded, and a curved rod segment 923 is provided at the bend position. The curved rod segment 923 is rotatably engaged with the rear plate 91. The second U-shaped segment 922 is used for manual control. By manually flipping the second U-shaped segment 922, the curved rod segment 923 can be rotated, and the bend 93 can be engaged with or disengaged from the rear positioning rod 7.

[0032] Furthermore, the rear plate 91 provided by this utility model has a box-like structure. The rear plate 91 is provided with shaft holes 911 that mate with both ends of the curved rod section 923, a support opening 912 that mates with the middle of the curved rod section 923, and an arc opening 913 that mates with the bend 93. Among them, the second U-shaped section 922 serves as a force-applying section, allowing the curved rod section 923 to rotate around the shaft holes 911. The support opening 912 is used to control the maximum rotation angle of the curved rod section 923, preventing the first U-shaped section 921 and the second U-shaped section 922 from deforming due to excessive flipping. The arc opening 913 can serve as a support point for the first U-shaped section 921 when the device is folded, thereby improving the space compactness of the device after folding.

[0033] To facilitate the folding and unfolding of this device, the present invention provides a front handle groove 51 and a rear handle hole 52 on the seat 5. The front handle groove 51 and the rear handle hole 52 provide handhold nodes, making it easy for workers to pry open and fold the seat 5, thereby causing the connected components to move together to complete the folding and unfolding.

[0034] To improve the stability of the device after deployment, the present invention provides a lower support block 10 and an upper support block 11 on the rear support tube 4 and the seat 5, respectively, which cooperate with the rear positioning rod 7. The supporting working surfaces of the lower support block 10 and the upper support block 11 are both cylindrical arc surfaces, which are used to support the rear positioning rod 7 from the upper and lower directions. Together with the front locking arm assembly 8 and the rear locking arm assembly 9, they ensure the stability and safety of the seat 5 when it is in use.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
