[0049] Example:

[0050] Please refer to Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the overall structure of the escalator 100; Figure 2 To remove Figure 1 A schematic diagram of the structure behind the middle shell 140.

[0051] The present embodiment provides a synchronously movable escalator 100 with handrails and steps 112, which includes a frame 110, two guardrails, and a plurality of steps 112, wherein the two guardrails are respectively connected to the two sides of the frame 110, and the plurality of steps 112 are arranged between the two guardrails for easy stepping. In addition, a handrail assembly 120 is arranged at both ends of each step 112, and the handrail assembly 120 includes a handrail rod 121; wherein the bottom of the handrail rod 121 is rotatably connected to the step 112, so that it can stand up or fall down and fit on the step 112. In order to drive the handrail rod 121 to rotate, the escalator 100 is also provided with four drive assemblies 130, and the drive assembly 130 is used to drive the handrail rod 121 to rotate so as to switch between the two states of standing up or falling down.

[0052] The basic structures of the frame 110 and the guardrail steps 112 in this embodiment are similar to those in the prior art, and thus will not be described in detail.

[0053] Please refer to Figure 1 , Figure 2 and Figure 3The handrail assembly 120 includes a handrail rod 121 and a toggle plate 124. The bottom of the handrail assembly 120 is rotatably connected to the two ends of the step 112, so that the handrail assembly 120 can stand up or fall down. When the handrail assembly 120 stands up, it can be used for people to hold on; when the handrail assembly 120 falls down and fits on the step ladder 112, it is convenient to run below the ground.

[0054] Specifically, the handrail 121 is a telescopic structure, which includes a rod body 122 and a mounting tube 123; the mounting tube 123 is a U-shaped structure, which includes a connecting rod 1232 and two tubes 1231, the connecting rod 1232 extends along the running direction of the ladder 112 and is rotatably connected to the ladder 112, and the two tubes 1231 are arranged in parallel and spaced apart and are respectively vertically connected to the two ends of the connecting rod 1232. The rod body 122 is also a U-shaped structure, which includes a handholding portion 1222 and two plug-in rods 1221, and the two plug-in rods 1221 are respectively vertically connected to the handholding portion 1222; the two plug-in rods 1221 are respectively slidably plugged into the two mounting tubes 123. When the two plug-in rods 1221 slide, the height of the handrail 121 can be adjusted accordingly.

[0055] Furthermore, a damper is provided between the plug rod 1221 and the mounting tube 123, and the plug rod 1221 can be moved relative to the mounting tube 123 by applying a certain pulling force or pressure to the plug rod 1221. The above design can prevent the plug rod 1221 from sliding arbitrarily relative to the mounting tube 123, and is also convenient for people to adjust according to their height needs.

[0056] Optionally, a roller 1223 is provided on the outside of the handrail rod 121; the handrail assembly 120 also includes two tension springs. The two tension springs are respectively arranged in the two mounting tubes 123, one end of the tension spring is connected to the plug rod 1221, and the other end is connected to the bottom of the mounting tube 123. When the handrail assembly 120 is erected, the tension spring can make the roller 1223 roll with the upper end surface of the guardrail. Since the height of the guardrail at different positions of the escalator 100 is different, the above design can make the height of the handrail rod 121 always consistent with the height of the guardrail, and when people press the handrail rod 121, it will not automatically shorten. The above design can improve the convenience and safety of the handrail assembly 120.

[0057] Further, a toggle plate is also provided at the bottom of the handrail 121, which is connected to the handrail 121 in an L shape. By pushing or pulling the toggle plate, the handrail 121 can be swung within a range of 90 degrees, that is, switched between the two states of standing up and falling down.

[0058] In order to apply external force to the toggle plate, the escalator 100 in this embodiment is further provided with four drive assemblies 130, and the four drive assemblies 130 have the same structure, two of which are arranged at the upper end of the escalator 100, and the other two are arranged at the lower end of the escalator 100. The two at the upper end are symmetrically arranged about the center line of the escalator 100, and the two at the lower end are symmetrically arranged about the center line of the escalator 100.

[0059] Please refer to Figure 4 The driving assembly 130 includes a driving motor 131, a crank 132, a connecting rod 133 and a sliding push-pull rod 134. The driving motor 131 is installed on the frame 110. One end of the crank 132 is vertically connected to the output shaft of the driving motor 131. One end of the connecting rod 133 is hinged to the crank 132, and the other end is hinged to the sliding push-pull rod 134. The sliding push-pull rod 134 is L-shaped and slides with the frame 110. The crank 132, the connecting rod 133, the sliding push-pull rod 134 and the frame 110 constitute a crank 132 slider mechanism. When the crank 132 rotates under the drive of the driving motor 131, it can drive the sliding push-pull rod 134 to reciprocate through the connecting rod 133. When the sliding push-pull rod 134 reciprocates, it can apply thrust or pull to the toggle plate at the bottom of the handrail 121, so that the handrail 121 stands up or falls down.

[0060] Specifically, the sliding push-pull rod 134 includes a sliding section 1342 and a push-pull section 1341, wherein one end of the sliding section 1342 is hinged to the connecting rod 133, and the other end is fixedly connected to the push-pull section 1341 in an L shape; the push-pull section 1341 is used to apply thrust or pull to the toggle plate at the bottom of the handrail rod 121.

[0061] In this embodiment, the escalator 100 is taken as an example. The two driving assemblies 130 at the lower end are used to drive the handrail assembly 120 on the step 112 that has just run from below the ground to above the ground to stand up, so as to facilitate handholding; the two upper driving assemblies 130 are used to drive the handrail assembly 120 on the step 112 that is about to run from the ground to below the ground to fall down, so as to prepare for the step 112 and the handrail assembly 120 to run below the ground.

[0062] In this embodiment, the push-pull section 1341 of the sliding push-pull rod 134 in the two driving assemblies 130 at the lower end is located on the inner side of the toggle plate. When the sliding push-pull rod 134 slides outward, it can pull the toggle plate through the push-pull section 1341, so that the handrail 121 stands up. When the step 112 below the ground moves to the position of the driving assembly 130 at the lower end, the sliding section 1342 is located on the side of the toggle plate away from the corresponding step 112 surface to prevent the sliding section 1342 from interfering with the toggle plate.

[0063] The push-pull section 1341 of the sliding push-pull rod 134 in the two driving assemblies 130 at the upper end is located on the outside of the toggle plate. When the sliding push-pull rod 134 slides inward, it can push the toggle plate through the push-pull section 1341, so that the handrail rod 121 falls down and fits on the corresponding step 112.

[0064] In order to ensure that the handrail 121 fits the corresponding step 112 more reliably, a magnet is provided on the handrail 121 so that the handrail 121 can be attracted to the corresponding step 112 .

[0065] In other downward escalators 100, the working principle is similar to that of the upward escalator 100, except that the two driving assemblies 130 at the upper end are used to drive the handrail 121 to stand up, and the two driving assemblies 130 at the lower end are used to drive the handrail 121 to fall down.

[0066] The working principle and beneficial effects of the escalator provided in this embodiment are as follows:

[0067] For an ascending elevator, when in use, passengers step on the step; when the step moves to the ground, the drive assembly at the lower end drives the handrail assembly to stand up, and the rollers of the handrail assembly just roll with the upper part of the guardrail. Since the distance from the upper part of the guardrail to the steps is not the same, and the handrail rod is a telescopic structure; therefore, the handrail rod can automatically adjust its height according to the above distance; when people hold on to the upper part of the handrail rod, the guardrail can support the handrail rod through the rollers to prevent it from automatically shortening under pressure. In addition, since the handrail assembly is directly connected to the step, it can ensure that the handrail assembly and the step run synchronously, thereby reducing the probability of people falling.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
