[0042] The following is a further detailed description of the technical solution of the utility model through specific embodiments and in combination with the accompanying drawings: Embodiment 1: Referring to Figures 1 to 7 As shown, a climbing pedal comprises: a supporting component 1, a positioning portion 2 and a supporting portion 15, and a part of the positioning portion 2 can be received in the supporting component 1.

[0043] The supporting member 1 is provided with a first receiving groove 11, which is provided along the length direction of the supporting member 1 and on the axis of the supporting member 1. One end of the positioning portion 2 is rotatably connected to the supporting member 1, and a hook 21 is provided at the end of the positioning portion 2 away from the supporting member 1; the positioning portion 2 is rotated so that the positioning portion 2 can be received in the first receiving groove 11.

[0044] The hook 21 includes a connecting portion 211, an abutting portion 212 and a limiting portion 213, which form a hanging opening 214. The radial size of the hanging opening 214 is adapted to the door lock, and the depth of the hanging opening 214 is not less than the diameter of the door lock. In this way, when the hook 21 is hung on the door lock, the door lock can be covered in the hanging opening 214 of the hook 21 and will not easily loosen.

[0045] Reinforced wing plates 12 are provided on both sides of the width direction of the lower end surface of the supporting component 1. The provision of the reinforced wing plates 12 can improve the overall strength of the supporting component 1. A shaft mounting hole 121 is provided through one end of the two reinforcing wing plates 12 in the length direction. A positioning shaft 13 is provided in the shaft mounting hole 121. The positioning shaft 13 is located at the bottom of the first receiving groove 11, and the axial direction of the positioning shaft 13 is perpendicular to the length direction of the first receiving groove 11. The positioning part 2 is rotatably provided on the positioning shaft 13; specifically, a rotating mounting member 22 is provided at one end of the positioning part 2 away from the hook 21, and a rotating mounting hole 221 is provided on the rotating mounting member 22. The positioning shaft 13 is penetrated in the rotating mounting hole 221, so that the rotating mounting member 22 can rotate around the positioning shaft 13. When the positioning part rotates toward the supporting component 1, the positioning part can be received in the first receiving groove 11.

[0046] The upper end surface of the supporting component 1 is provided with uniformly distributed anti-skid bosses 14, which have an anti-skid function and effect.

[0047] In addition, in order to make the structure more stable when the hook 21 is hung on the door lock, an abutment limit portion 23 is provided on the positioning portion 2, so that when the hook 21 is hung on the door lock, a person's foot steps on the supporting component 1, and the abutment limit portion 23 can abut against the upper end surface of the supporting component 1.

[0048] The support portion 15 in this embodiment is fixedly arranged at one end of the supporting component 1 close to the positioning shaft 13, and the support portion 15 and the supporting component 1 are an integrally formed structure. A buffer component 3 is arranged on the support portion 15, and the buffer component 3 is an independent and detachable structure. The buffer component 3 includes a buffer body 31 and a decorative splint 32, and two decorative splints 32 are arranged, and the two decorative splints 32 are respectively arranged at both ends of the length direction of the buffer body 31. A buffer installation groove 311 that matches the support portion 15 is arranged in the length direction of the buffer body 31. When in use, the buffer installation groove 311 matches the support portion 15, that is, the support portion 15 is inserted into the buffer installation groove 311; the decorative splint 32 is clamped on both sides of the width direction of the supporting component 1, that is, the decorative splint 32 is clamped on the outer side of the reinforcing wing plate 12. At the same time, in order to facilitate the coordination between the decorative splint 32 and the reinforced wing panel 12, a wing panel positioning hole 122 is provided on the reinforced wing panel 12, and a splint positioning pin 321 is provided on the decorative splint 32. When the buffer component 3 is installed on the support portion 15, the buffer mounting groove 311 and the support portion 15 cooperate with each other, and the splint positioning pins 321 and the wing panel positioning holes 122 on the decorative splints 32 on both sides cooperate with each other to achieve positioning coordination.

[0049] The support part 15 and the supporting component 1 in this embodiment are both integrally formed structures. Specifically, the support part 15 is formed at one end of the supporting component 1 close to the positioning shaft 13. It is preferably a surface structure, for example, it can be formed by bending the supporting component 1 downward. When the hook 21 is hung on the door lock, the support part 15 is against the door frame. On the one hand, the force between the support part 15 and the door frame is balanced with the hook force between the hook 21 and the door lock, avoiding the relative rotation of the hook 21 relative to the door lock, so that the hook 21 and the door lock cooperate more firmly; on the other hand, it can also optimize the stability of the supporting component 1 and play the role of auxiliary support of the support part 15. In order to avoid unnecessary indentations on the door frame due to excessive load during use, in this embodiment, the surface of the support portion 15 is also covered with a buffer component 3, which includes a buffer body 31 covering the surface of the support member 15 and a decorative splint 32 for connecting with the supporting member 1. The buffer body 31 is made of a flexible material and has a certain thickness. When bearing load, the deformation caused by the extrusion force increases the contact surface with the door frame, reducing the possibility of damage to the door frame; the decorative splint 32 can be integrally formed with the buffer body 31, and is bent relative to the buffer body 31 on both sides toward the supporting member 1. The decorative splint 32 is provided with a positioning pin 321 for fixing the buffer component on the supporting member 1. The above-mentioned buffer component is preferably made of materials such as rubber or silicone.

[0050] Two reinforced abutment blocks 4 are arranged on the positioning shaft 13, and an abutment block mounting hole 41 is arranged on the reinforced abutment block 4, and the positioning shaft 13 is penetrated through the abutment block mounting hole 41; the two reinforced abutment blocks 4 are respectively arranged on both sides of the rotating mounting member 22, and the two reinforced abutment blocks 4 just fill the gap between the rotating mounting member 22 and the reinforced wing plate 12, so that the rotating mounting member 22 can stably rotate on the positioning shaft 13 when rotating.

[0051] At the same time, inclined abutment surfaces 42 are arranged on the two reinforcing abutment blocks 4, and the inclined abutment surfaces 42 face one side of the supporting portion 15. An inclined abutment rib 312 is arranged on the buffer body 31. The inclined abutment rib 312 can not only improve the buffering effect of the buffer body 31, but also when the support member and the supporting portion 15 are matched, the inclined abutment rib 312 can match with the inclined abutment surface 42, so that a transmission structure close to each other can be formed among the reinforcing abutment block 4, the inclined abutment rib 312, the buffer body 31 and the supporting portion 15, so that when a person's foot stands on the supporting component 1, the weight of the body is transmitted to the buffer body 31 through the supporting component 1, the reinforcing abutment block 4, the inclined abutment rib 312, the buffer body 31 and the supporting portion 15, thereby improving the bearing capacity of the supporting component 1 and improving the overall service life. Two buffer bolt holes 313 are penetrated on the buffer body 31, and a reinforcing bolt hole 43 is provided on the reinforcing abutment block 4. The positions of the two buffer bolt holes 313 correspond to the positions of the reinforcing bolt holes 43 on the two reinforcing abutment blocks 4, and the bolts pass through the buffer bolt holes 313 and are connected with the reinforcing bolt holes 43.

[0052] In addition, a nut mounting hole 44 is provided at the end of a reinforced abutment block 4 close to the reinforced wing plate 12. The nut mounting hole 44 is hexagonal, and a limiting nut 45 is provided in the nut mounting hole 44. A threaded connection section 131 cooperating with the limiting nut 45 is provided on the positioning shaft 13, and a limiting end head 132 is provided at the end of the positioning shaft 13 so that the positioning shaft 13 can cooperate with the nut. The limiting end head 132 and the limiting nut 45 are respectively abutted against the two sides of the reinforced wing plate 12, so that the positioning shaft 13 can be fixedly set on the reinforced wing plate 12.

[0053] The supporting member 1 in this embodiment is formed in one piece, that is, the reinforcing wing plate 12 and the supporting portion 15 are formed in one piece, so that the overall structure can be more solid. On both sides of the first receiving groove 11 in the width direction, a receiving baffle 111 is also formed in one piece, and on the reinforcing abutting block 4, a yielding inclined surface 46 is provided to prevent interference with the receiving baffle 111.

[0054] The climbing pedal in this embodiment has two states, namely a storage state and a normal use state;

[0055] Storage state: the positioning part 2 is rotated so that the positioning part 2 is stored in the first storage groove 11, thereby reducing the overall volume and facilitating transportation and storage;

When the hook 21 is hung on the door lock 5, the two sides of the hook 21 can be limited by the two sides of the door lock, thereby reducing the shaking of the positioning part, so that when a person stands on the supporting component 1, it can be more stable.

[0059] Example 3: Reference Figures 9 to 11 As shown, a climbing pedal comprises: a supporting component 1, a positioning portion 2 and a supporting portion 15, and the supporting portion 15 can be received on the supporting component 1.
