[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figures 1-3 This utility model provides an embodiment of a liftable toilet height increaser, comprising four support rods 1. The support rods 1 support the entire height increaser, ensuring its stability during use. Sliding rods 14 are slidably connected inside the support rods 1, causing subsequent handrails 11 to slide, thus adjusting the height of the height increaser. Handrails 11 are fixedly connected between the tops of two adjacent sliding rods 14, facilitating standing or sitting while using the height increaser. A fixing component is provided inside the sliding rods 14 to fix the adjusted handrails 11, ensuring their stability. A first connecting rod 2 is fixedly connected to the bottom of the handrail 11, enhancing the structural strength of the support rods 1 and providing installation space for other components. Rotating sleeves 3 are fixedly connected to the rear of opposite sides of the two first connecting rods 2, providing installation space for rotating rods 4 and facilitating their rotation. An internal rotating rod 4 is connected to the outer rod 5. The two rotating rods 4 are used to connect the outer rod 5, and the rotation of the rotating rod 4 drives the outer rod 5 to rotate. The outer rod 5 is fixedly connected between the outer walls of the two rotating rods 4. The outer rod 5 provides the installation base for the toilet seat 7. At the same time, the rotation of the outer rod 5 drives the rotation of the toilet seat 7, thereby meeting the functional requirements of the lift-up type. Two second connecting rods 6 are fixedly connected to the front side of the outer wall of the outer rod 5. The second connecting rods 6 provide the support base for the toilet seat 7, so that the toilet seat 7 can be placed stably. A fixing rod 9 is fixedly connected to the side of the second connecting rod 6 away from the outer rod 5. The fixing rod 9 is used to connect the two second connecting rods 6 and is fixed to the first connecting rod 2 by the locking component on its outer wall. The toilet seat 7 is set between the top of the outer walls of the two second connecting rods 6. The toilet seat 7 provides a comfortable use environment for the user. Locking components are fixedly connected to both sides of the fixing rod 9. The locking components lock with the first connecting rod 2, further enhancing the stability of the entire toilet lift structure.

[0037] Reference Figure 7 and Figure 8The fixing component includes a limiting plate 15, the outer wall of which is slidably connected to the inside of the slide rod 14. The limiting plate 15 is used to limit the locking rod 16, preventing the locking rod 16 from sliding out of the slide rod 14 and causing the fixing component to lose its function. The locking rod 16 is fixedly connected to one side of the limiting plate 15. The locking rod 16 is engaged with the positioning hole 13 to achieve the fixing effect of the slide rod 14. The spring 17 is fixedly connected to the other side of the limiting plate 15. When fixing the item, the spring 17 can generate elastic force through its own elastic deformation, so that the locking rod 16 always maintains a certain tension, thereby better fixing the item. When the fixing is released, the elastic force of the spring 17 can drive the limiting plate 15 and the locking rod 16 to return to their original positions for easy use next time.

[0038] Reference Figure 5 The engaging assembly includes a second locking block 10, which is fixedly connected to the outer wall of the fixing rod 9. The bottom of the second locking block 10 engages with the front part of the outer wall of the first connecting rod 2. This engagement method further enhances the stability of the connection structure between the toilet seat 7 and the armrest 11. During the user's use of the toilet seat 7, the second locking block 10 can effectively prevent the fixing rod 9 and the toilet seat 7 connected to it from shifting or shaking relative to the first connecting rod 2.

[0039] Reference Figure 4 A first locking block 8 is fixedly connected to the rear bottom of the toilet seat 7. The first locking block 8 and the outer rod 5 engage, further strengthening the connection stability between the toilet seat 7 and the outer rod 5. When using the toilet seat 7, the engagement structure between the first locking block 8 and the outer rod 5 can withstand the pressure applied by the user to the toilet seat 7, preventing the toilet seat 7 from shifting off the outer rod 5 during use. At the same time, it also allows the toilet seat 7 to rotate with the outer rod 5, thus achieving a liftable effect.

[0040] Reference Figures 6-8 The support rod 1 has multiple positioning holes 13 on its outer wall. The locking rod 16 passes through the slide rod 14 and engages with the positioning holes 13, allowing the slide rod 14 to be fixed at multiple different height positions. Users can adjust the height of the toilet riser according to their actual needs.

[0041] Reference Figure 7 combine Figure 8 Two third connecting rods 12 are fixedly connected between the two front support rods 1. The middle part of the third connecting rod 12 is arc-shaped. The third connecting rod 12 enhances the stability of the connection structure on the front side of the toilet riser. At the same time, the arc-shaped design of the third connecting rod 12 can better fit the front side of the toilet, so that the toilet riser can be placed directly above the toilet.

[0042] Reference Figure 1 and Figure 2The top of the outer wall of the armrest 11 is fitted with an anti-slip sleeve 18. The anti-slip sleeve 18 increases the friction between the user's hand and the armrest 11, so that the user can firmly grip the armrest 11 even when the hand is wet or sweaty. The two armrests 11 are inverted V-shape. The inverted V-shape prevents collision with the armrest 11 when the toilet seat 7 is lifted. At the same time, it also makes it easier for the user to sit down and stand up when using the riser.

[0043] Reference Figure 1 and Figure 2 The bottom of the support rod 1 is equipped with an anti-slip pad, which increases the friction between the toilet riser and the ground, preventing the toilet riser from sliding on the ground during use.

[0044] Working principle: When an elderly person or a patient with limited mobility needs to use the toilet, the height increaser is brought to the bathroom and placed directly above the toilet, so that the third connecting rod 12 fits against the front wall of the toilet. Then, the height of the height increaser is adjusted according to the user's height. At this time, by pressing the locking rod 16, the limiting plate 15 will slide and the spring 17 will be compressed, storing potential energy. After the locking rod 16 is fully retracted into the positioning hole 13, the handrail 11 can be pulled up or pressed down, so that the patient can be in a comfortable environment when using the height increaser.

[0045] Subsequently, the spring 17 releases its stored potential energy, thereby pushing the limiting plate 15 to slide. When the limiting plate 15 slides, it drives the locking rod 16 to slide. When the locking rod 16 slides, it engages with the limiting plate 15, thereby fixing the armrest 11 and ensuring the stability of the riser during use. Then, the toilet seat 7 is rotated. When the toilet seat 7 rotates, it drives the outer rod 5 to rotate through the first locking block 8. When the outer rod 5 rotates, it drives the second connecting rod 6 to rotate, and at the same time drives the fixing rod 9 to rotate. When the two fixing rods 9 rotate to be perpendicular to the first connecting rod 2, the second locking block 10 can engage with the first connecting rod 2 to fix the toilet seat 7, and then it can be used.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
