Under the action of external force, the locking pin 7 can disengage from the slot 32, thereby... The foot pad 3 can be detached from the support frame 1. The foot pad 3 in this structure helps to reduce the damage of the toilet ladder to the ground and makes it convenient for users. The support frame 1 is inserted into the insertion groove 31 on the foot pad 3, and the locking pin 7 is driven by the elastic element 71 to cooperate with the locking groove 32, so that the support frame 1 and the foot pad 3 are relatively fixed. This structure facilitates the quick disassembly and installation of the support frame 1 and the foot pad 3, which is convenient for the assembly of the toilet ladder and the storage after disassembly. Moreover, the support frame 1 and the foot pad 3 are less damaged during disassembly and installation, which facilitates the frequent disassembly and assembly of the support frame 1 and the foot pad 3 and helps to extend the service life of the toilet ladder.

[0045] The foot pad 3 described in this utility model is provided with two sets of insertion slots 31. The two sets of support frames 1 can respectively cooperate with the two sets of insertion slots 31 on the foot pad 3 and fix the two sets of support frames 1. This structure is conducive to the stable installation of the two sets of support frames 1, improves the structural strength of the toilet ladder, and helps to extend the service life of the toilet ladder.

Both the main support rod 11 and the auxiliary support rod 12 are provided with locking pins 7 and elastic elements 71. The lower ends of the main support rod 11 and the auxiliary support rod 12 are detachably connected to the foot pads 3. The V-shaped arrangement of the main support rod 11 and the auxiliary support rod 12 helps to improve the stability of the toilet ladder. Since the lower ends of the main support rod 11 and the auxiliary support rod 12 are detachably connected to the foot pads 3, damage to the ground by the main support rod 11 and the auxiliary support rod 12 is avoided, making it convenient for users. In this embodiment, the main support rods 11 on the two sets of support frames 1 cooperate with two sets of insertion slots 31 on the same foot pad 3, and the auxiliary support rods 12 on the two sets of support frames 1 cooperate with two sets of insertion slots 31 on the same foot pad 3.

[0047] The pedal assembly 4 is rotatably mounted on the auxiliary support rod 12 via a locking assembly 5. The locking assembly 5 includes a threaded third connector 51 and a locking member 52.

The locking member 52 cooperates with the third connecting member 51 to prevent the limiting block from disengaging from the first limiting part 513. In this structure, since the third connecting member 51 is rotatably connected to the pedal assembly 4 and relatively fixed to the auxiliary bracket, the connection between the third connecting member 51 and the locking member 52 will not become loose during the rotation of the pedal assembly 4. This facilitates the use of the toilet ladder and prevents the installation of the pedal assembly 4 from becoming loose after long-term use, which would affect the safety of the toilet ladder.

[0048] In this invention, the main support rod 11 and the auxiliary support rod 12 are rotatably connected by a connecting device 13. The connecting device 13 includes a threaded first connector 131 and a second connector 132. The first connector 131 and the second connector 132 cooperate to keep the main support rod 11 and the auxiliary support rod 12 connected. The main support rod 11 is provided with a second hinge hole 113 adapted to the first connector 131. The first connector 131 cooperates with the second hinge hole 113 to rotatably connect the first connector 131 to the main support rod 11. The auxiliary support rod 12 is provided with a second limiting hole 122. The first connector 131 is provided with a baffle 133. The first connector 131 passes through the second hinge hole 113 and cooperates with the second limiting hole 122, with the baffle 133 abutting against the end of the second hinge hole 113. The second connector 132 is located on one side of the second limiting hole 122. The first connector 131 cooperates with the second limiting hole 122 to connect the first connector 131 to the auxiliary support rod 12. The rod 12 rotates synchronously. In this structure, the first connecting member 131 rotates synchronously with the auxiliary support rod 12. The first connecting member 131 is rotatably connected to the main support rod 11. During the relative rotation of the main support rod 11 and the auxiliary support rod 12, the auxiliary support rod 12 cannot drive the first connecting member 131 and the second connecting member 132 to rotate relative to each other. This is beneficial for the stable installation of the main support rod 11 and the auxiliary support rod 12, and prevents the first connecting member 131 and the second connecting member 132 from loosening during the unfolding and folding of the main support rod 11 and the auxiliary support rod 12. This facilitates the use of the toilet ladder and prevents the main support rod 11 and the auxiliary support rod 12 from becoming loose after long-term use, which would affect the safety of the toilet ladder. Preferably, the second connecting member 132 is provided with a control groove 137. During the connection and disassembly of the first connecting member 131 and the second connecting member 132, the first connecting member 131 and the auxiliary support rod 12 are relatively fixed. The user can control the relative rotation of the second connecting member 132 and the first connecting member 131 through the control groove 137.

[0050] In this embodiment, the main support rod 11 is provided with a limiting swing groove 114, and the first connecting member 131 is provided with a limiting protrusion 136 adapted to the limiting swing groove 114. When the auxiliary support rod 12 rotates relative to the main support rod 11, the auxiliary support rod 12 drives the first connecting member 131 to rotate, and the limiting protrusion 114 swings in the limiting swing groove 123. The setting of the limiting protrusion 136 and the limiting swing groove 114 can limit the rotation angle of the main support rod 11 and the first connecting member 131, thereby limiting the rotation angle of the main support rod 11 and the auxiliary support rod 12, avoiding the main support rod 11 and the auxiliary support rod 12 from having an excessively large unfolding angle, and facilitating the stable unfolding of the main support rod 11 and the auxiliary support rod 12.

[0051] In this utility model, the locking pin 7 and the elastic element 71 are preferably integrated, and the insertion groove 31 is preferably provided with a locking groove 32 on both sides. The main support rod 11 and the auxiliary support rod 12 are both made of hollow tubes. The main support rod 11 and the auxiliary support rod 12 are provided with through holes 111 on both sides. The elastic element 71 drives the locking pin 7 to pass through the through hole 111 and cooperate with the locking groove 32.
