[0030] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] The present embodiment provides a new type of safety guide shoe, including a guide shoe body 1, with transversely extending anti-slip blocks 3 on both sides of the bottom of the guide shoe body 1 for preventing the guide shoe body 1 from slipping out of the T-shaped groove of the hall door sill 2, a long hole 4 is provided in the middle of the guide shoe body 1, a roller 5 is inserted in the long hole 4, the roller 5 is connected to the guide shoe body 1 through a pin shaft 6 inserted from the bottom of the guide shoe body 1, and the pin shaft 6 is also equipped with limit gaskets 11 arranged at the upper and lower ends of the roller 5.

[0034] like Figure 2 , Figure 3 , Figure 4 As shown, the present embodiment provides a new type of safety guide shoe, including a guide shoe body 1, and both sides of the bottom of the guide shoe body 1 are provided with anti-slipping blocks 3 extending laterally to prevent the guide shoe body 1 from slipping out of the T-shaped groove of the hall door sill 2. A long hole 4 is provided in the middle of the guide shoe body 1, and a roller 5 is inserted in the long hole 4. The roller 5 is connected to the guide shoe body 1 through a pin shaft 6 inserted from the bottom of the guide shoe body 1. The pin shaft 6 is also provided with limiting gaskets 11 arranged at the upper and lower ends of the roller 5. The limiting gasket 11 effectively limits the upward and downward movement of the roller 5, so that the roller 5 is firmly connected to the guide shoe body 1 as a whole. The guide shoe long hole 4 has the roller 5 built in. Under normal circumstances As the hall door 8 moves, the roller 5 and the guide shoe body 1 are driven to roll along the groove of the sill 2. However, the existing guide shoe has a single structure and no roller 5. When the hall door moves, the guide shoe and the groove are friction-guided. The new safety guide shoe adds a roller 5, and changes the traditional friction guide mode to a sliding guide, thereby reducing friction loss and extending the service life. At the same time, when the lower part of the hall door 8 is hit, the safety guide shoe is stuck in the T-shaped groove of the hall door sill 2 under the joint action of the roller 5 and the anti-drop block 3 integrally formed with the guide shoe, preventing the safety guide shoe from falling out of the T-shaped groove, thereby preventing the hall door 8 from falling out, and ensuring the safety of people in the elevator.

[0035] like Figure 4 As shown, the guide shoe body 1 and the anti-slip stopper 3 of this embodiment are integrally formed, which enhances the strength of the safety guide shoe. The safety guide shoe is not easily damaged when it is hit, and can effectively prevent the hall door from slipping out.

[0036] The guide shoe body and the anti-drop block in this embodiment are both made of polytetrafluoroethylene.

[0037] like Figure 3 As shown, the sum of the widths of the two anti-slip blocks 3 and the guide shoe body 1 of this embodiment is smaller than the diameter of the roller 5 , which facilitates the roller 5 to roll along the groove of the sill 2 as the hall door 8 moves.

[0038] like Figure 3 As shown, the diameter of the roller 5 of this embodiment is greater than the thickness of the guide shoe body 1. Adding the roller 5 changes the guide shoe body from a conventional friction guide mode to a rolling guide mode, thereby reducing friction loss, reducing vibration and noise during operation, and extending the service life.

[0039] The roller 5 of this embodiment is made of polytetrafluoroethylene.

[0040] like Figure 2 , Figure 3 As shown, the width of the anti-slip block 3 of this embodiment is greater than the width of the T-shaped groove notch of the hall door sill 2. When the lower part of the hall door is hit, the guide shoe body is deformed and easily slips out of the groove. At this time, the anti-slip block 3 and the roller 5 are stuck in the groove of the sill 2 to prevent the hall door 1 from slipping out.

[0041] The material of the anti-dropping stopper 3 of the present embodiment is polytetrafluoroethylene.

[0042] like Figure 3 , Figure 4 and Figure 5 As shown, the present embodiment provides a hall door sill installation structure, comprising a hall door 8 and a hall door sill 2, a guide shoe connecting plate 7 is detachably installed at the bottom of the hall door 8, a plurality of new safety guide shoes as described above are installed at intervals along the length of the guide shoe connecting plate 7, the bottom end of each new safety guide shoe is installed in a T-shaped groove of the hall door sill 2, and the specially designed hall door sill clamps the roller 5 in the guide shoe long hole 4 in the interface of the sill 2, even if the lower part of the hall door 8 is hit by external force, the hall door 8 will not fall off the sill, so that people will not fall into the shaft, thereby ensuring the safety of passengers.

[0043] like Figure 3 As shown, a groove is provided on the top of the guide shoe body 1, and the guide shoe connecting plate 7 is tightly inserted into the groove and glued together using acrylic glue. This connection method has good environmental adaptability and is durable.

[0044] like Figure 5 As shown, the guide shoe connecting plate 7 of this embodiment is connected to the lower part of the hall door 8 by screws 9, which is convenient for disassembly and assembly and easy for maintenance and replacement.

[0045] like Figure 2 , Figure 3 As shown, the width of the T-shaped groove of the hall door sill 2 of this embodiment is smaller than the diameter of the roller 5, and the roller 5 is stuck in the groove of the sill 2, and the roller 5 and the anti-slip block 3 prevent the hall door from slipping out.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
