[0023] The present invention is described in further detail below with reference to the accompanying drawings and embodiments.

[0024] Example 1

[0025] A multi-section aisle suction cup handrail, such as Figure 1 As shown, it includes a support rod 1 and a positioning suction cup 2. Each support rod 1 is combined with the positioning suction cup 2 to form an armrest unit. Several armrest units are combined to form a multi-segment suction cup armrest. The multi-segment suction cup armrest includes more than three positioning suction cups 2. Two adjacent positioning suction cups 2 are connected by a support rod 1. The axes of every two adjacent support rods 1 are in the same straight line or there is an angle between the axes; the support rod 1 and the positioning suction cup 2 are detachably connected or fixedly connected.

[0026] like Figure 2-5 As shown, the positioning suction cup 2 includes a middle suction cup 2a and an end suction cup 2b. The middle suction cup 2a is located between the two support rods 1. The middle suction cup 2a has a first joint 21 and a second joint 22 extending in different directions respectively. The first joint 21 and the second joint 22 are respectively connected to the support rod 1. The end suction cup 2b is extended with a first joint 21 or a second joint 22, wherein at least the second joint 22 is a detachable joint, and the second joint 22 is detachably connected to the support rod 1.

[0027] like Figure 5 As shown, the connection end of the second joint 22 is located in the middle of the positioning suction cup 2 and is rotatable relative to the positioning suction cup 2 . The connection position between the first joint 21 and the positioning suction cup 2 is in a yield position relative to the second joint 22 .

[0028] like Figure 4 As shown, the first joint 21 is a fixed joint, and the first joint 21 is fixedly connected to the support rod 1.

[0029] like Figure 3 As shown, the end of the support rod 1 is provided with a marble 11 connected to a spring, and the second joint 22 is provided with a connecting hole for the end of the support rod 1 to extend into, and a limiting hole is radially extended from the connecting hole to cooperate with the marble 11.

[0030] like Figure 2As shown, an exhaust button 23 is provided on the fixed joint or connecting joint of each positioning suction cup 2, and a reset spring 24 is provided between the exhaust button 23 and the positioning suction cup 2. When the exhaust button 23 is in the pressed state, the space inside the positioning suction cup 2 is connected to the outside world. When the exhaust button 23 is in the rebound state, the space inside the positioning suction cup 2 is isolated from the outside world.

[0031] Each positioning suction cup 2 is provided with a prompt device 25 and a trigger head 26 connected to the prompt device 25. The trigger head 26 is used to judge the vacuum degree of the positioning suction cup 2. The trigger head can be axially movably installed on the mounting seat, and the mounting seat is fixedly connected to the positioning suction cup 2. The trigger head 26 extends out or is flush with the bottom of the positioning suction cup 2. A compression spring is provided on the top of the trigger head. The trigger head is arranged in the shell, and the other end of the compression spring is connected to the shell. The trigger assembly can measure the vacuum degree in the suction cup in real time by measuring the distance between the trigger head and the mounting surface, and judge whether the suction cup is firmly adsorbed. When the adsorption is not firm or there is air leakage, a reminder is issued to the user. The user can reinstall the handrail according to the reminder to ensure the safety of the handrail.

[0032] One of the armrest units located at the ends is composed of a support rod 1 and positioning suction cups 2 at both ends. Except for the armrest units at both ends, the remaining armrest units are composed of a support rod 1 and a positioning suction cup 2.

[0033] Working principle: The handrail is installed on a smooth wall. First, install the first handrail unit and fix the positioning suction cups 2 at one or both ends of the first handrail unit on the wall. As one embodiment, you can first install a handrail unit with two positioning suction cups 2 on the side, determine the position of the initial section, and fix the positioning suction cups 2 to the wall by pressing. Furthermore, the positioning suction cups 2 can be pressed by pressing the exhaust button 23 and then pressing it to discharge the gas in the positioning suction cups 2, forming a negative pressure relative to the outside world, so that the positioning suction cups 2 are fixed to the wall. One of the positioning suction cups 2 has a second joint 22 for fixing the next group of handrail units. First, determine the installation position of this group of handrail units. The second joint 22 is connected to the support rod 1. The support rod 1 extends into the second joint 22 and connects to it. Then, rotate the support rod 11 to drive the second joint 22 to rotate accordingly. Then, fix the positioning suction cup 2 at the other end of the support rod 11 in the same way. If there are more handrail units in the future, continue to adjust the desired angle in this way and continue to install. After the installation is completed, the trigger head 26 detects whether the vacuum degree in each positioning suction cup 2 meets the requirements. If the measured pressure is higher than the set value or the distance between the suction cup trigger head and the wall is greater than the set value, the signal is transmitted to the prompt device 25. The prompt device 25 has multiple prompting methods. The installation of the prompt device 25 can be hidden in the first joint 21 or the second joint 22, or it can be visible to the user. For example: the prompt device 25 can, but is not limited to, prompt the user through prompting methods such as changing the color of the light, making sounds, and sending messages. The conventional prompting method that is easy for personnel in the cost field to know can be changed according to needs, thereby improving the safety performance of the handrail.
