Detailed Description

The technical scheme of the application is further described in detail below with reference to the accompanying drawings.

The embodiment of the application discloses a climbing ladder. Referring to fig. 1, a climbing ladder includes a top plate 1, a left ladder 12 and a right ladder 13 hinged to the top plate 1. A limiting rope is arranged between the left ladder 12 and the right ladder 13 and used for placing the left ladder 12 and the right ladder 13 with overlarge angle when being opened.

The left side ladder 12 and the right side ladder 13 are both hinged with an auxiliary rod 21, the end part of the auxiliary rod 21 is provided with an auxiliary wheel 22, the left side ladder 12 and the right side ladder 13 are both provided with a fixed column 2, the fixed column 2 is provided with a tension spring 23, and the other end of the tension spring 23 is fixedly arranged on the auxiliary rod 21.

Limiting columns 24 for limiting the position of the auxiliary rod 21 are arranged on the left side ladder 12 and the right side ladder 13, and the limiting columns 24 are located above the fixed columns 2. Wherein, the limit posts 24 are two, and when the auxiliary rod 21 is abutted against the upper limit posts 24, the auxiliary wheel 22 faces upwards; when the auxiliary lever 21 abuts against the lower stopper post 24, the auxiliary wheel 22 is directed downward, and the lower end surfaces of the auxiliary wheel 22 are lower than the lower end surfaces of the left and right ladders 12 and 13.

The tension spring 23 provides a pulling force to the auxiliary rod 21, when the auxiliary rod 21 is directed upwards, the auxiliary rod 21 can be prevented from rotating downwards under the action of the tension spring 23, and the ascending ladder is the conventional ascending ladder at the moment, so that the ascending ladder is the most stable in use.

When auxiliary rod 21 is directed downwards and has the contained angle with left side ladder 12 or right side ladder 13, under the effect of extension spring 23, can make auxiliary rod 21 produce decurrent thrust, and the lower tip butt to subaerial of left side ladder 12 and right side ladder 13 is passed through the effect of self gravity when the operation personnel is on the ladder of ascending a height, when the body gravity of personnel on the ladder of ascending a height is less than the pulling force of extension spring 23, then can make auxiliary wheel 22 support subaerial, therefore the operation personnel is when the operation in-process removes or other personnel assist when removing, more laborsaving.

When the auxiliary rod 21 is downward and parallel to the left ladder 12 or the right ladder 13, the auxiliary wheel 22 can be always supported on the ground under the action of the dead weight of the tension spring 23 and the ascending ladder, and the auxiliary wheel is convenient to move during use. So that the position of the auxiliary lever 21 can be set by itself according to the use scene.

Referring to fig. 2, the fixing post 2 has an L-shaped structure, and a plurality of through holes for fixing the tension springs 23 are formed in the fixing post 2 at equal intervals. The tension spring 23 is arranged in the through hole adjacent to the auxiliary rod 21, the stretching amplitude of the tension spring 23 is small, and the tension is small; the tension spring 23 is arranged in the through hole far away from the auxiliary rod 21, the tension amplitude of the tension spring 23 is large, and the tension force is large, so that the tension spring 23 can be arranged in the proper through hole according to the weight of a user.

It should be noted that all directional indicators (such as up, down, left, right, front, and rear) in the embodiments of the present utility model are merely used to explain the relative positional relationship, movement conditions, etc. between the components in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicators are changed accordingly.

In addition, in the description of the present utility model, the meaning of "plurality" means at least two, for example, two, three, etc., unless specifically defined otherwise.

In the present utility model, unless explicitly specified and limited otherwise, the terms "connected," "configured," and the like are to be construed broadly, and for example, "configured" may be either fixedly connected, detachably connected, or integrated; can be mechanically or electrically connected; either directly or indirectly, through intermediaries, or both, may be in communication with each other or in interaction with each other, unless expressly defined otherwise. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

The embodiments of the present application are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in this way, therefore: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
