At present, when the panel 2 and the bottom plate are installed and connected, first, the bottom plate 1 and corresponding components are fixed on the escalator, and then the panel 2 is covered on the bottom plate 1. When assembling the panel 2, it is necessary to debug and fit the panel 2 and the bottom plate 1, determine the relative positions of the two, and then drill the holes on the bottom plate 1 according to the hole positions on the panel 2 using a hand drill. Finally, the panel 2 and the bottom plate 1 are connected and fixed by screws. In the above method, it is difficult to accurately position the relative positions between the panel 2 and the bottom plate 1, and there are deviations in the drilled hole positions.

[0027] The following will elaborate on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0028] As Figures 3 - 6 shown is a handrail belt entrance and exit assembly of an escalator according to this embodiment. The handrail belt entrance and exit assembly is installed at the entrance and exit positions of the escalator to prevent people or objects from being caught and injured by the running handrail belt. The handrail belt entrance and exit assembly includes a bottom plate 1 and a panel 2. Among them, the bottom plate 1 is fixed to the escalator by bolts. The bottom plate 1 has a front side and a back side in a first direction. The first direction is defined as the thickness direction of the bottom plate 1. A handrail belt guide 11 is fixed to the bottom plate 1 by bolts. A handrail belt access channel 111 extending in the first direction is formed on the handrail belt guide 11. The handrail belt of the escalator can move in the handrail belt access channel 111. A plurality of assembly holes 12 penetrating the front side and the back side are distributed and processed on the bottom plate 1. The assembly holes 12 can be round holes, waist-shaped holes or cross-shaped holes. The size of the assembly holes 12 is determined according to the actual design.

[0029] The aforementioned panel 2 covers the front side of the bottom plate 1. An avoidance opening 21 corresponding to the handrail belt access channel 111 is processed on the panel 2. When the panel 2 covers the bottom plate 1, the handrail belt guide 11 is inserted into the avoidance opening 21. The four peripheral edges of the aforementioned panel 2 are formed with bending edges by sheet metal bending. When the panel 2 covers the bottom plate 1, the bending edges wrap around the outside of the bottom plate 1, thereby covering the bottom plate 1. A fixed connection assembly is installed between the bottom plate 1 and the panel 2. Through this fixed connection assembly, the bottom plate 1 and the panel 2 are fixed to each other.

[0030] In this embodiment, the aforementioned fixed connection components are arranged corresponding to each assembly hole 12, and include a cylinder 3, a first limiting block 4, a second limiting block 5, and a screw 6. Among them, the cylinder 3 is a cylindrical pin structure, a threaded section 31 is machined on the outer peripheral surface of the cylinder 3, and a threaded hole 32 is machined on the end surface of the cylinder 3. In this embodiment, the threaded hole 32 penetrates through the cylinder 3 along the length direction of the cylinder 3. The central axis of the threaded hole 32 coincides with the central axis of the cylinder 3. The aforementioned cylinder 3 is inserted into the assembly hole 12, the length direction of the cylinder 3 is arranged in the same direction as the aforementioned first direction, and an adjustment gap is formed between the cylinder 3 and the assembly hole 12, through which the cylinder 3 can move and adjust its position in the assembly hole 12. And when the cylinder 3 is inserted into the assembly hole 12, the aforementioned threaded hole 32 faces the panel 2.

[0031] In this embodiment, the aforementioned first limiting block 4 is arranged on the back side of the bottom plate 1, and the first limiting block 4 is fixedly connected to the cylinder 3, so that a limiting fit is formed between the first limiting block 4 and the back side of the bottom plate 1 in the first direction. The first limiting block 4 is sleeved outside the cylinder 3 and is welded to the cylinder 3. The aforementioned second limiting block 5 is arranged on the front side of the bottom plate 1, and a threaded through hole is machined on the second limiting block 5. The second limiting block 5 is threadedly connected to the threaded end on the cylinder 3 through the threaded through hole, so that the second limiting block 5 is detachably connected to the cylinder 3. A limiting fit is formed between the second limiting block 5 and the front side of the bottom plate 1 in the first direction. Through the above structural design, under the limiting action of the first limiting block 4 and the second limiting block 5, the cylinder 3 is restricted from moving in the first direction and can move in the remaining directions in the assembly hole 12.

[0032] Among them, a through hole 22 is machined on the panel 2 corresponding to the assembly hole 12, and a positional deviation is allowed between the assembly hole 12 and the through hole 22. The aforementioned screw 6 penetrates through the panel 2 through the through hole 22 and is threadedly connected to the threaded hole 32 on the cylinder 3. Through the connection of the screw 6, the panel 2 and the cylinder 3 are relatively fixed, and then the panel 2 is fixed on the bottom plate 1.

[0033] During specific assembly, the bottom plate 1 is fixed to the escalator by bolts. The column body 3 is inserted into the assembly hole 12 from the back side of the bottom plate 1. The first limiting block 4 fixedly connected to the column body 3 is located on the back side of the column body 3. The second limiting block 5 is threadedly connected to the column body 3 from the front side of the bottom plate 1. The panel 2 is covered on the bottom plate 1 from the front side of the bottom plate 1. The screw 6 is inserted into the through hole 22 on the panel 2. By finely adjusting the position of the column body 3 in the assembly hole 12, the threaded hole 32 on the column body 3 is made to correspond to the screw 6, and the screw 6 is threadedly connected and locked with the threaded hole 32 to realize the connection and fixation of the panel 2 and the bottom plate 1. In the above method, during assembly, through the limiting cooperation of the first limiting block 4 and the second limiting block 5, the movement of the column body 3 on the bottom plate 1 along the first direction can be restricted. An adjustment gap is formed between the column body 3 and the assembly hole 12 to be able to adjust the position of the column body 3 in the assembly hole 12, and thus the threaded hole 32 on the column body 3 can be made to correspond to the hole position on the panel 2. The panel 2 and the threaded hole 32 are connected and locked by the screw 6, and thus the relative fixation between the panel 2 and the bottom plate 1 is realized. With the combination of the above methods, the connection and fixation between the panel 2 and the bottom plate 1 are simple, efficient, time-saving and labor-saving, effectively meeting the on-site assembly requirements of the escalator.

[0034] The above are only the embodiments of the present invention, and do not thus limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
