Of course, the rotating seat 200 can also be rotatably connected to the connecting seat 100 via other structures, such as being rotatably connected to the connecting seat 100 via a long articulated shaft arranged in the left and right directions.

[0035] In an embodiment, a plurality of fixers 300 are provided, and the fixation control mechanism 400 is configured to control all the fixers 300 to act synchronously, thereby improving the stability of fixation and the convenience of operation.

[0038] In the embodiment, the fixer 300 adopts a suction cup, which is easy to fix on a smooth building surface. It is conceivable that in some embodiments, the fixer 300 is not limited to using a suction cup. For example, for some buildings built with poles, the fixer 300 can also be some clamps, which can be fixed by clamping the poles of the building.

[0039] In some embodiments, in order to simplify the structure and reduce the cost, the fixed control mechanism 400 is provided with a pull rope, and the fixed control mechanism 400 controls the fixer 300 through the pull rope. By setting the pull rope to control the fixer 300, manual control can be performed, the cost is low, and the pull rope can be extended to the ground, so that the fixer 300 can be controlled on the ground.

[0040] In the embodiment, a plurality of the fixing devices 300 are arranged and arranged at intervals along the left and right directions on the rotating base 200, and can be fixed to a plane such as a wall. For some buildings, such as poles, the following structure can be adopted (refer to Figure 5 ): The rotating seat 200 is provided with an arc-shaped plate 210, and the fixer 300 is a suction cup. A plurality of fixers 300 are provided and are arranged at intervals along the arc-shaped extension direction of the arc-shaped plate 210.

With the above structure, when installing and fixing the device of this embodiment, the left plug-in slot and the right plug-in slot can be plugged and matched with the two ends of the top of the ladder 1, so as to achieve the fixation of the device of this embodiment and the ladder 1. The above ladder top fixing structure 110 has a simple structure and is easy to install. Of course, it is conceivable that the ladder top fixing structure 110 is not limited to the above embodiment, for example, a clamp can also be used to fix it to the top of the ladder 1 by clamping and fixing, or a threaded fastener can be used to fix it. It can be understood that in this field, there are many implementation methods for achieving fixation between components, and those skilled in the art can configure according to actual conditions.

[0043] In this embodiment, for the technical solution of manually controlling the fixer 300 by using a pull rope, the following structure can be adopted: the fixer 300 is a suction cup, and the suction cup is provided with a control handle 310. When the control handle 310 is pulled, the suction cup can be controlled to adsorb the contact surface, and when the control handle 310 is reset, the suction cup can release the adsorption. The fixing control mechanism 400 includes a connecting arm 410, a driving arm 420, and a pull rope. The connecting arm 410 is connected to the control handle 310 of the suction cup, and the driving arm 420 is connected to the connecting arm 410. When the driving arm 420 moves, it can drive the connecting arm 410 to move and reset to link the control handle 310 to move and reset. The pull rope is connected to the driving arm 420 and is used to drive the driving arm 420 to move. When fixing, the driving arm 420 is pulled by the pull rope to move, and the driving arm 420 drives the connecting arm 410 to move, and the connecting arm 410 links the control handle 310 to realize the control of the suction cup.

[0044] In an embodiment, a plurality of suction cups are provided, and the connecting arm 410 can be fixed to the control handles 310 of the plurality of suction cups at the same time, thereby driving the plurality of suction cups to adsorb and release the adsorption synchronously, and the provision of a plurality of fixers 300 can also enhance the stability of the fixation. In an embodiment, the suction cups are arranged in a row along the left-right direction, so that the connecting arm 410 can be conveniently connected. The connecting arm 410 can specifically be provided with a clamp corresponding to the suction cup to fix the corresponding control handle 310, or it can also be fixed by a threaded fastener.

[0045] In the embodiment, the driving arm 420 is pivoted to the rotating seat 200. When the driving arm 420 rotates forward and backward, it can control the movement and reset of the connecting arm 410 respectively. The driving arm 420 is provided with a first connecting end 421 and a second connecting end 422. The pull rope includes a driving rope and a reset rope. The driving rope and the reset rope are respectively connected to the first connecting end 421 and the second connecting end 422. When the driving rope and the reset rope are pulled respectively, they can drive the driving arm 420 to rotate forward and backward respectively. The driving rope and the reset rope are used to drive the driving arm 420 to rotate forward and backward respectively, thereby driving the connecting arm 410 to move and reset, so as to realize the movement and reset of the control handle 310 of the suction cup. The structure is simple and easy to implement. It is conceivable that in some embodiments, a single pull rope can also be used to control the movement and reset of the control handle 310 of the suction cup. For example, the structure of some oscillating fans with pull ropes can be referred to.

[0046] In an embodiment, the rotating seat 200 is provided with a guide groove 220, the connecting arm 410 cooperates with the guide groove 220 and can slide along the guide groove 220, the guide groove 220 is used to guide the trajectory of the movement of the connecting arm 410, the driving arm 420 is provided with a matching groove 423, the connecting arm 410 slides and cooperates with the matching groove 423, and the driving arm 420 drives the connecting arm 410 to move along the extension trajectory of the guide groove 220 through the matching groove 423.

[0047] In the embodiment, the control handle 310 of the suction cup is rotatable. In the initial state, the control handle 310 is perpendicular to the suction surface of the suction cup. After the control handle 310 is rotated 90 degrees to one side, the suction surface of the suction cup is concave, so that the suction cup adsorbs the contact surface. The guide groove 220 can be an arc groove. The center of the arc extension trajectory of the arc groove, the pivot axis of the driving arm 420, and the rotation axis of the control handle 310 are coaxial. When the driving arm 420 rotates, it can push the connecting arm 410 to make an arc motion and directly rotate the control handle 310 90 degrees, thereby realizing the control operation of the suction cup. Of course, it is conceivable that the guide groove 220 is not limited to the use of an arc groove, and can be adaptively set according to the operation method of the control handle 310 of the suction cup.

[0048] In the embodiment, the guide grooves 220 are arranged in pairs on the left and right sides of the rotating seat 200, the connecting arm 410 is arranged along the left and right directions, and the two ends of the connecting arm 410 are respectively slidably arranged in the guide grooves 220 on the corresponding sides, so that the movement is stable. In the embodiment, two driving arms 420 can be provided and matched with the two ends of the connecting arm 410 in a one-to-one correspondence, and both driving arms 420 can be connected to the pull rope, so that the movement of the connecting arm 410 can be controlled from both ends, the force is balanced, and the movement is stable.

[0049] It is conceivable that the connecting arm 410 and the driving arm 420 are not limited to realizing the linkage with the control handle 310 of the suction cup through the above-mentioned structure. For example, the connecting arm 410 and the driving arm 420 are connected to form a connecting rod mechanism. Those skilled in the art can reasonably configure the linkage cooperation method between the connecting arm 410 and the driving arm 420 according to actual conditions.

[0050] In an embodiment, an angle positioning mechanism for positioning the angle position of the rotating seat 200 relative to the connecting seat 100 can be provided, so that the angle position of the ladder 1 can be locked, and the stability of use can be improved. Specifically, the angle positioning mechanism may include a bayonet, which is telescopically and movably arranged on the connecting seat 100, and the rotating seat 200 is provided with a plurality of bayonet holes, which are arranged around the rotating axis of the rotating seat 200, and the bayonet can be inserted into the bayonet hole to position the angle position of the rotating seat 200 relative to the connecting seat 100. The angle positioning mechanism is also provided with a bayonet driving structure for driving the bayonet action, so as to realize the action of the bayonet withdrawing from the bayonet hole and reinserting into the bayonet hole. The bayonet driving structure can be an electric driving structure of an electric push rod, an electromagnet, etc., or a driving structure of a connecting rod mechanism, a cam, etc. that needs to be driven manually. The angle positioning mechanism can be controlled by a fixed control mechanism 400, and the fixed control mechanism 400 can be configured to synchronously control the angle positioning mechanism and the fixer 300 to respectively perform the angle positioning of the rotating seat 200 and the fixation of the building, so as to complete the external fixation of the ladder 1.

When it exceeds a predetermined range, the controller controls the alarm to sound an alarm.

[0053] In an embodiment, the controller may also record the number of times the ladder 1 is used and the duration of use, so as to monitor the aging degree of the ladder 1.

[0054] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments.
