[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1-Figure 2 The utility model provides an embodiment of a stable child climbing ladder, comprising a support frame 1, a lower step 2 is fixedly connected to the inner lower side of the support frame 1, and a standing board 3 is fixedly connected to the inner center of the support frame 1. The child can climb up the standing board 3 through the lower step 2 to complete the standing. The upper inner side of the support frame 1 is fixedly connected with a protective rod 4. The protective rod 4 can protect the child standing on the standing board 3, and the child will not walk around at will, which increases safety. Moreover, when the child stands on the climbing ladder, the child can carry out daily activities such as washing and eating without making noise, which reduces the workload of adults. A moving rod 5 is arranged below the protective rod 4, and the moving rod 5 can cooperate with the protective rod 4 to further protect the child, ensuring that the child will not easily fall from the ladder. At the same time, the moving rod 5 can perform linear movement in the up and down directions. When the moving rod 5 moves upward, it can avoid obstacles for the child to climb up the standing board 3, and when the moving rod 5 moves downward, it can restore the protection of the child.

[0034] Reference Figure 3-Figure 5 The left and right ends of the moving rod 5 are fixedly connected with sliders 6. The two sliders 6 on the left and right sides of the moving rod 5 are respectively slidably connected to the inside of the two slide grooves 7 on the left and right sides of the support frame 1. The inner wall surfaces on the left and right sides of the support frame 1 are provided with slide grooves 7. The sliders 6 can perform linear motion in the up and down directions inside the slide grooves 7. Through the cooperation of the sliders 6 and the slide grooves 7, the moving rod 5 can be slidably connected to the inside of the support frame 1 and perform linear motion in the up and down directions. A buffer unit is arranged inside the slide groove 7, and the buffer unit includes an elastic member 71. The elastic member 71 Fixedly connected to the bottom surface of the slide groove 7, the upper end of the elastic member 71 is fixedly connected with a rubber block 72. When the moving rod 5 drives the slider 6 to move downward under the action of gravity, the slider 6 will contact the rubber block 72 and squeeze the elastic member 71, so that the elastic member 71 is compressed to generate elastic potential energy, and then the gravitational potential energy of the slider 6 is buffered and offset by the elastic potential energy of the elastic member 71, thereby preventing the slider 6 from falling at a high speed and contacting and colliding with the inner wall of the slide groove 7, causing the connection between the slider 6 and the moving rod 5 to be broken and damaged, thereby affecting the service life of the ladder.

[0035] A card slot 8 is provided on the inner wall surface of the rear side of the support frame 1. There are two card slots 8, and the two card slots 8 are arranged in a vertical linear array structure. A card connection unit is provided inside the mobile rod 5. The card connection unit includes a mounting slot 81. The mounting slot 81 is provided on the left side surface of the mobile rod 5. A spring 82 is fixedly connected to the right inner wall surface of the mounting slot 81. A card block 83 is fixedly connected to the left end of the spring 82. The card block 83 is plugged into the mounting slot 81. The card block 83 can perform linear motion in the left and right directions inside the mounting slot 81. The left end of the card block 83 is connected to the inner card of the card slot 8. Then, when the slider 6 moves to the uppermost part of the slide slot 7, the block 83 will be aligned with the upper slot 8. When the moving rod 5 moves downward, the block 83 can be aligned with the lower slot 8. The front surface of the block 83 is fixedly connected with a pull rod 84. When the pull rod 84 moves, it can drive the block 83 to move synchronously. A through groove 85 is provided on the front inner wall surface of the mounting groove 81. The pull rod 84 passes through the through groove 85. The pull rod 84 can perform a linear motion in the left and right directions inside the through groove 85, thereby avoiding the moving rod 5 from hindering the movement of the pull rod 84.

[0036] Reference Figure 1 and Figure 6 A groove 9 is provided at the bottom end of the support frame 1, and a rotating plate 10 is hinged inside the groove 9. A rubber pad 11 is fixedly connected to the bottom surface of the rotating plate 10. When the rotating plate 10 is in a horizontal state, it will rotate into the inside of the groove 9, and the inner wall of the rotating plate 10 will fit with the inner wall of the groove 9, so that the rotating plate 10 can be limited, so that the rotating plate 10 remains stable. At this time, the bottom surface of the rubber pad 11 fits with the ground, and the bottom surface of the rubber pad 11 is provided with anti-slip grooves, which can increase the friction between the ground and the climbing ladder, so that the climbing ladder can be placed on the ground more stably for use, and the deviation of the climbing ladder when used by young children can be reduced. To protect the safety of young children, a screw 12 is provided above the rotating plate 10, and the bottom end of the screw 12 passes through the rotating plate 10. The screw 12 and the rotating plate 10 are threadedly connected. When the screw 12 is rotated, it can perform linear motion in the up and down directions relative to the rotating plate 10. A screw hole 13 is provided on the inner wall surface of the support frame 1. When the climbing ladder is finished using, the user can rotate the rotating plate 10 to fit with the inner wall of the support frame 1. At this time, the screw 12 will be aligned with the screw hole 13. The user can fix the rotating plate 10 by twisting the screw 12 into the screw hole 13, thereby realizing the storage and fixation of the rotating plate 10 and reducing the space occupied by the climbing ladder when it is stored.

[0037] Working principle: When a child needs to use the climbing ladder, an adult can turn the screw 12 to release the fixation of the rotating plate 10, turn the rotating plate 10 into the groove 9, and then place the climbing ladder to the desired position. After placement, the adult can pull the pull rod 84 to drive the block 83 to move to the right, leaving the inside of the slot 8, release the clamping fixation of the moving rod 5, and then lift the moving rod 5 upward to move the slider 6 to the upper end of the slide groove 7. At this time, the block 83 will be aligned with the upper slot 8, and the block 83 will be elastic under the spring 82. Under the action of potential energy, it pops up into the upper card slot 8 to clamp and fix the moving rod 5, so that the moving rod 5 does not hinder the child from climbing onto the standing board 3. At the same time, there is no need to remove the moving rod 5 from the climbing ladder, so as to avoid the moving rod 5 being lost or needing to be found, which affects the use efficiency. After the child reaches the standing board 3, the above steps can be repeated to make the moving rod 5 move downward to complete the clamping and fixing, so as to protect the child and prevent the child from falling from the climbing ladder. Then the child can move independently on the climbing ladder and complete daily activities such as washing, eating, etc.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
