Description

Technical Field

[0001] The utility model belongs to the technical field of escalators and relates to a combined handrail structure. Background Art

[0002] like Figure 6 As shown, in the prior art, most escalator handrail structures include a plurality of handrail cover plates 10 spliced ​​together, a guide rail (not marked in the figure) is arranged on the handrail cover plate 10, and a handrail belt (not marked in the figure) movable relative to the handrail cover plate 10 is arranged on the guide rail. During installation, it is necessary to connect the plurality of handrail cover plates 10 together, install the guide rail on the handrail cover plate 10, and slide the handrail belt to the guide rail. Specifically, a connecting plate 20 is arranged on the bottom surface of each handrail cover plate 10 near the end. During installation, two connecting plates 20 located on different handrail cover plates 10 are connected by connecting bolts 30 to realize the connection between the two handrail cover plates 10. The handrail cover 10 is connected, but after the two armrest cover plates 10 are connected together in the above manner, the direct force-bearing objects between the two armrest cover plates 10 are the connecting plate 20 and the connecting bolts 30. In order to connect the two connecting plates 20 through the connecting bolts 30, the connecting plate 20 needs to maintain a vertical state with the armrest cover plates 10. If the connecting bolts 30 are tightened too much or a large force is generated between the two armrest cover plates 10, the connecting plate 20 will be easily bent due to the large hardness of the connecting bolts 30 and the difficulty in deformation, resulting in the connection between the two armrest cover plates 10. Dislocation, that is, a gap is generated between the two armrest cover plates 10. Summary of the invention

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0023] Embodiment 1

[0024] like Figure 1 — Figure 3 As shown, a combined handrail structure of the utility model includes a cover plate 100 , a connecting plate 200 and a slot 220 .

[0025] A combined handrail structure of the utility model comprises: at least two cover plates 100, the bottom surfaces of two adjacent cover plates 100 are connected by a connecting plate 200, a plurality of waist holes 210 are provided at one side of each connecting plate 200, a plurality of slots 220 are opened at the other side of each connecting plate 200, left bolts 110 of the same number as the waist holes 210 are installed on one cover plate 100, the left bolts 110 pass through the corresponding waist holes 210, and right bolts 120 of the same number as the slots 220 are installed on another adjacent cover plate 100, a left nut 111 is installed on each of the left bolts 110, there is an extrusion force between the left nut 111 and the connecting plate 200, each of the right bolts 120 passes through the corresponding slots 220, a right nut 121 is installed on each of the right bolts 120, there is an extrusion force between the right nut 121 and the connecting plate 200.

[0026] In the present invention, the two cover plates 100 connected to the connecting plate 200 are respectively referred to as a first cover plate 100 and a second cover plate 100 .

[0027] When connecting the two first cover plates 100 and the second cover plate 100, people need to pass each left bolt 110 through the first cover plate 100 and the corresponding waist hole 210 on the connecting plate 200, and then tighten the left nut 111 on the corresponding left bolt 110, so that the connecting plate 200 can be assembled with the first cover plate 100. After that, people need to pass the right bolt 120 through the second cover plate 100, and then align the end of the second cover plate 100 with the end of the first cover plate 100, and make the right bolt 120 0 can be inserted into the corresponding slot 220, and then a nut is tightened on the corresponding right bolt 120, so that the first cover plate 100 and the second cover plate 100 can be connected through the connecting plate 200, that is, the parallel setting of the connecting plate 200 and the cover plate 100 is realized, so that when the first cover plate 100 and the second cover plate 100 are subjected to force, the connecting plate 200 is not easy to bend unless the connecting plate 200 is broken, so that the connection strength between the first cover plate 100 and the second cover plate 100 can be effectively improved.

[0028] Furthermore, when assembling the first cover plate 100 and the second cover plate 100, whether the first cover plate 100 and the second cover plate 100 are flush can be determined by whether each right bolt 120 is inserted into its corresponding slot; in addition, when the connecting plate 200 and the first cover plate 100 are installed, because the length of the waist hole 210 is greater than the diameter of the left bolt 110, the width of the waist hole 210 is equal to the diameter of the left bolt 110, thus, the waist hole 210 provides a larger moving space for the left bolt 110, that is, the first cover plate 100 and the connecting plate 200 have a larger installation margin during installation.

[0029] A guide rail 130 is laid on the top surface of the cover plate 100 , and a handrail 131 is slidably connected to the guide rail 130 . When the escalator is working, the handrail 131 moves along the track of the guide rail 130 .

[0030] A reinforcement plate 132 is installed in the guide rail 130, and the projection of the reinforcement plate 132 in the direction of the cover plate 100 covers the connection between the two adjacent cover plates 100. The outer surface of the reinforcement plate 132 is in contact with the inner wall of the guide rail 130, and the cross-sectional shape of the reinforcement plate 132 is U-shaped. By setting the reinforcement plate 132, the firmness of the guide rail 130 at the connection between the two cover plates 100 can be strengthened. Furthermore, the two ends of the reinforcement plate 132 are respectively connected to the adjacent cover plates 100 by reinforcement bolts 133. In this way, the connection strength between the first cover plate 100 and the second cover plate 100 can be improved.

[0031] Embodiment 2

[0032] like Figure 4 As shown, the difference between this embodiment and the first embodiment is that a reinforcing plate 230 is additionally provided in this embodiment on the basis of the first embodiment.

[0033] Specifically, a plurality of parallel reinforcing plates 230 are provided on the bottom surface of the connecting plate 200, and each reinforcing plate 230 is perpendicular to the side of the connecting plate 200. By providing a plurality of reinforcing plates 230, the hardness of the connecting plate 200 can be effectively improved, so that the connecting plate 200 can withstand greater bending force.

[0034] Embodiment 3

[0035] like Figure 5 As shown, the difference between this embodiment and the first embodiment is that a gear bar 240 is additionally provided in this embodiment on the basis of the first embodiment.

[0036] When the right bolt 120 is inserted into the corresponding slot 220 and there is an extrusion force between the right nut 121 and the connecting plate 200, if an external force forces the first cover plate 100 to separate from the second cover plate 100, that is, when the right bolt 120 slides relative to the slot 220, since the connecting plate 200 is provided with baffles on both sides of each slot 220, the baffles will block the right nut 121, so that the right bolt 120 can be prevented from sliding in the slot 220, thereby ensuring a stable connection between the connecting plate 200 and the second cover plate 100.
