Generally, the landing door jamb includes a cross beam and columns which are connected and combined with each other. The landing door device is installed on the cross beam through a fixing bracket. The landing door device is a conventional device in the prior art, which is arranged above the landing door jamb and includes components such as an upper sill frame, landing door guide rails fixed on the upper sill frame, pulleys, door hanging plates, etc. The door hanging plate is suspended on the landing door guide rails through the pulleys. By moving back and forth on the landing door guide rails through the pulleys, the opening and closing of the landing door are realized.

[0003] As Figure 1 、 2 shown is a connection method between a landing door jamb and a landing door device 1 in the prior art. In this connection method, the cross beam 2 of the landing door jamb is made into a C-shaped structure, and the cross beam 2 is clamped by a fixing bracket 3 and a lower baffle 22 to play a fixing role. The upper sill frame 12 of the landing door device 1 is connected to the cross beam 2 through the fixing bracket 3. In the above connection method, the cross beam 2 needs to be designed as a C-shaped structure and needs to be supported by the lower baffle 22, resulting in high manufacturing costs, and the disassembly and assembly are cumbersome, time-consuming and laborious. In addition, the bottom of the upper sill frame 12 is connected to the fixing bracket 3, and the connection strength of the entire landing door device 1 is insufficient. When the landing door device 1 is subjected to an external impact, the connection between the landing door device 1 and the landing door jamb is not stable enough, and it is difficult to meet the use requirements of the elevator in a complex environment. Summary of the Utility Model

[0004] Aiming at the above existing technical problems, the purpose of the utility model is to provide a fixing bracket for connecting a landing door jamb and a landing door device, which can simplify the structure of the cross beam, reduce the manufacturing cost, and is convenient to disassemble. The connection between the landing door device and the landing door jamb is stable and reliable, enabling the landing door device to effectively cope with external impacts and effectively meeting the use requirements of the elevator in a complex environment.

[0005] The technical solution of the utility model is realized as follows: A fixing bracket for connecting a landing door jamb and a landing door device,

[0006] The landing door jamb includes a cross beam;

[0007] The landing door device includes an upper sill frame and a bent guide rail arranged on the upper sill frame and extending forward and backward; the bent guide rail has a U-shaped bent structure and an inverted U-shaped bent structure arranged at intervals left and right; a bent groove is formed by enclosing inside the inverted U-shaped bent structure;

[0009] Furthermore, the lifting structure is integrally formed on the fixing bracket.

[0010] Furthermore, the landing door device includes a pulley; the top surface of the inverted U-shaped bending structure is an arc surface adapted to the pulley groove.

[0011] Furthermore, the lifting structure is a hook-shaped structure; the inserting part is formed at the tip position of the hook-shaped structure; the lifting part is formed at the bending position of the hook-shaped structure.

[0012] Furthermore, the second fixing section extends in the up-and-down direction; the second fixing section and the upper sill bracket or the bending guide rail are connected by bolts; threaded holes corresponding to the bolts are provided on the second fixing section.

[0023] The following elaborates 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.

[0024] As Figures 3-4 shown, this embodiment proposes a fixing bracket 3 for connecting the landing door jamb and the landing door device 1, and the connection between the landing door device 1 and the landing door jamb can be achieved through this fixing bracket 3. The landing door jamb in this embodiment is a conventional structure of the prior art. The landing door jamb is formed by combining a cross beam 2 and columns 21. The cross beam 2 is embedded above the landing door opening, and the columns 21 are arranged on opposite sides of the landing door opening. The landing door device 1 is a conventional structure of the prior art, which is arranged above the landing door jamb and functions to open and close the landing door.

[0025] The landing door device 1 in this embodiment includes an upper sill frame 12 and a bent guide rail 5 installed on the upper sill frame 12 and extending forward and backward. In this embodiment, through the method of sheet metal bending, the bent guide rail 5 is integrally formed on the upper sill frame 12. The pulley 13 of the landing door device 1 cooperates with the bent guide rail 5 to be able to move on the bent guide rail 5. Among them, the bent guide rail 5 in this embodiment is formed by sheet metal bending, and the bent guide rail 5 has U-shaped bending structures 52 and inverted U-shaped bending structures 51 arranged at intervals left and right. An inverted U-shaped bending groove is formed inside the inverted U-shaped bending structure 51. Among them, the top surface of the inverted U-shaped bending structure 51 is an arc surface adapted to the wheel groove of the pulley 13, and the pulley 13 can move back and forth along the top surface of the inverted U-shaped bending structure 51.

[0026] The fixing bracket 3 of this embodiment includes a first fixing section 31 fixedly connected to the cross beam 2, a second fixing section 32 fixedly connected to the upper sill bracket 12 or the bending guide rail 5, and a connecting transition section 33. The above-mentioned connecting transition section 33 is connected between the first fixing section 31 and the second fixing section 32. Among them, the second fixing section 32 extends in the up and down direction, and the second fixing section 32 and the upper sill bracket 12 or the bending guide rail 5 are fixedly connected by bolts 4. Threaded holes 321 are machined on the second fixing section 32 corresponding to the bolts 4. The above-mentioned bolts 4 are threadedly connected to the threaded holes 321 to fixedly connect the second fixing section 32 and the upper sill bracket 12 or the bending guide rail 5. The first fixing section 31 extends in the horizontal direction (the left and right direction in this embodiment), and the first fixing section 31 and the cross beam 2 are connected by bolts 4. During specific assembly, the first fixing section 31, the cross beam 2, and the column 21 can be fixedly connected to each other by bolts 4.

[0027] Among them, a lifting structure 34 is integrally formed on the fixing bracket 3. The lifting structure 34 has an insertion part 341 that forms an up and down plug-in fit with the bending groove, and a lifting part 342 that forms an up and down abutting fit with the bottom of the U-shaped bending structure 52. Through the cooperation of the insertion part 341 and the bending groove, the mutual positioning between the fixing bracket 3 and the bending guide rail 5 can be realized. Through the mutual cooperation of the lifting part 342 and the U-shaped bending structure 52, the bending guide rail 5 can be lifted and supported, effectively preventing the bending guide rail 5 from sagging. Specifically, the lifting structure 34 is a hook-shaped structure. The insertion part 341 is formed at the tip position of the hook-shaped structure. The lifting part 342 is formed at the bending position 343 of the hook-shaped structure. An arc-shaped groove is machined on the lifting structure 34 at the bending position 343. The bottom of the aforementioned U-shaped bending structure 52 is accommodated in this arc-shaped groove.

[0028] When the fixing bracket 3 is specifically used, the insertion part 341 of the lifting structure 34 is inserted into the inner bending groove of the inverted U-shaped bending structure 51 to form a positioning fit, so as to be able to limit the left and right swing of the bending guide rail 5. At the same time, the lifting part 342 of the lifting structure 34 abuts against the U-shaped bending structure 52 up and down, so as to be able to lift the bending guide rail 5, thereby being able to strengthen the support for the guide rail. The first fixing section 31 of the fixing bracket 3 is fixedly connected to the cross beam 2 of the landing door jamb through bolts 4, and the second fixing section 32 of the fixing bracket 3 is connected to the bending guide rail 5 through bolts 4. Through the above method, the cross beam 2 does not need to be designed as a U-shaped structure, and at the same time, the lower baffle 22 can also be cancelled. The combination of the above methods can simplify the structure of the cross beam 2, reduce the manufacturing cost, and is convenient for disassembly. The connection between the landing door device 1 and the landing door jamb is stable and reliable, enabling the landing door device 1 to effectively cope with external impacts and effectively meet the use requirements of the elevator in complex environments.
