[0028] The multifunctional safety device of the elderly activity building of the present invention has the following working principle: when facing the elderly activity buildings, venues and other environments, combined with the particularity of the physical fitness of the middle-aged and elderly, the traditional handrails in the elderly activity buildings cannot play an auxiliary force role for the elderly, and the conventional handrails in ramps, narrow corridors and other sections are not friendly to the elderly and cannot play an auxiliary role. The present invention provides a multifunctional safety device, more precisely, a handrail that assists walking and climbing, each of which is placed at any point in the elderly activity building where a handrail is needed, so the length of the device is not specifically limited. In order to better demonstrate the significance of the present device in practical application, an example is given, where the present device is adapted to be installed on one side wall of a corridor with a ramp, and the elderly can walk to the power-assisting mechanism without a caregiver. 1 Near the bottom of the slope, press and hold the control button A104 according to the prompt posted on the fixed plate A103. Among them, the control button A104, the control button B106, the control button C133, and the control button D134 are adjustment buttons for controlling the operation of the device, including but not limited to the functions of direction movement and immediate stop. After pressing the control button A104, the motor A108 and the motor B115 are started synchronously. When the motor A108 is started, the worm A110 is driven to rotate through the coupling A109. When the motor B115 is started, the worm B117 is driven to rotate through the coupling B116. Among them, due to the structural properties of the worm A110 and the worm B117, when the output shaft of the motor A108 rotates in the opposite direction to the output shaft of the motor B115, the turbine is driven The shaft 123 moves linearly along the worm A110 and the worm B117, and when the output shaft of the motor A108 rotates in the same direction as the output shaft of the motor B115, the turbine shaft 123 is driven to rotate. When the turbine shaft 123 moves linearly along the worm A110 and the worm B117, it drives the shaft seat C119 to slide along the optical axis A121 and the optical axis B122. The slider seat A129 drives the shield 132 to follow the linear movement through the rack 125, the connecting block A126, the connecting block B127, the slider seat B130, and the slide seat 131. When the motor A108 and the motor B115 move to the front of the elderly, the elderly can adjust the up and down height of the shield 132 through the control button A104 according to their needs, and continue to start the motor A108 and the motor B115. 5. The output shafts of the two motors rotate in the same direction, and the turbine shaft 123 is driven to rotate. When the turbine shaft 123 rotates, the gear 124 is driven to rotate. The gear 124 drives the rack 125 to slide along the slide seat 131. When sliding, the rack 125 drives the fixed shaft 128 to slide along the through hole of the slider seat B130 through the connecting block A126 and the connecting block B127, so as to ensure the flatness of the shield 132. The shield 132 drives the control button C133, the control button D134, the armrest A135, the armrest B136, and the lock 137 to move up and down with the rack 125 until the elderly adjust the appropriate height and release the control button A104. Then the motor A108 and the motor B115 stop running. The elderly hold the armrest A135 or the armrest B136.Then press the control button D134, the baffle 132 moves linearly as described above, driving the elderly to move slowly forward. Of course, the moving speed of the baffle 132 can also be adjusted by the control buttons C133 and D134. However, for safety reasons, when the baffle 132 is adjusted to the origin at any end of the outer cover plate 102, the increase or decrease rate of the motor A108 and the motor B115 adjusted during the movement of the elderly will all be restored to the default speed, so as to ensure the safety of the elderly. If the elderly are not strong enough or their physical fitness is not enough to support holding the armrest with one hand, the power expansion mechanism 2 can be rotated along the lock 137 to be parallel to the body, and then the elderly will hold the threaded connecting tube 212 and the column bracket A201 and the column bracket B202 with both hands flat. If the threaded connecting tube 212 is still not long enough, press the limit block 214. The limit block 21 4 When rotating along the tube mouth bracket 216, the spring 215 is squeezed, and the threaded connecting tube 212 is pulled outward. When pulling, the pushing tube 211 is driven to move outward along the column bracket A204, and the connecting block 210 is driven to move when moving. The connecting block 210 drives the belt 206 to follow the movement through the positioning block B209, and the belt 206 drives the pulley A205 and the pulley B207 to rotate when the belt 206 moves. The design here not only establishes the working stroke of the pushing tube 211 but also makes its structure run smoothly, ensuring that the elderly have the ability to use it. When the pushing tube 211 is pulled out to a certain length, the limit block 214 is released. The limit block 214 rebounds upward to the initial state under the action of the spring 215. At this time, the pin of the limit block 214 is inserted into the through hole of the pushing tube 211 to limit the movement of the pushing tube 211. The elderly hold the power-assisting expansion mechanism 2 with both hands, and assist in climbing and walking under the drive of the power-assisting mechanism 1. ,

[0029] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention also fall within the protection scope of the present invention.
