DETAILED DESCRIPTION

[0025] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0026] Example:

[0027] Reference Figure 1-Figure 5 The utility model discloses a detachable, reinforced and protected integrated elevator door cover installation component, comprising a door frame 1, a hall door 2 is slidably arranged on the back side of the door frame 1, a rotating chamber 3 is arranged inside the door frame 1 at a position corresponding to the hall door 2, a rotating shaft rod 4 is arranged inside the rotating chamber 3, an opening and closing door 5 is fixedly arranged on the outer surface of the rotating shaft rod 4, a driving gear 6 is sleeved on the bottom end of the rotating shaft rod 4, a positioning bracket 7 is arranged at the bottom end of the driving gear 6, a linkage gear 61 is arranged inside the rotating chamber 3, the linkage gear 61 is meshed with the driving gear 6, and a staggered mechanism 8 is arranged at the connection between the driving gear 6 and the rotating shaft rod 4, an installation groove 9 is opened at a position corresponding to the driving gear 6 on the bottom side of the hall door 2, a transmission tooth plate 10 is fixedly arranged inside the installation groove 9, and the transmission tooth plate 10 is meshed with the linkage gear 61.

[0028] In this embodiment, when the hall door 2 of the elevator is opened, the transmission gear plate 10 is set, and when the hall door 2 of the elevator moves in parallel, the driving gear 6 is driven to rotate by the linkage gear 61, so that the rotating shaft 4 rotates, and then the opening and closing door 5 is driven to unfold, and a semicircular trajectory is formed in the process of the opening and closing door 5 unfolding outward, so that the passengers close to the hall door 2 are away from the hall door 2, so as to achieve the effect of improving the protection of the door frame;

[0029] Specifically, when the elevator hall door 2 is opened, the transmission tooth plate 10 is moved in parallel, so that the transmission tooth plate 10 drives the linkage gear 61 to rotate during the translation process. Since the linkage gear 61 is meshed with the driving gear 6, and the driving gear 6 is connected to the rotating shaft 4 through the staggered mechanism 8, the driving gear 6 can drive the driving shaft to rotate during the rotation process, so as to achieve the effect of controlling the opening and closing of the opening and closing door 5. Moreover, since the number of teeth of the transmission tooth plate 10 is greater than the number of teeth of the driving gear 6, after the opening and closing door 5 contacts the door frame 1, the staggered mechanism 8 is set to enable the driving gear 6 to continue to rotate, so that the driving gear 6 can contact the end side of the transmission tooth plate 10.

[0030] Furthermore, during the closing process of the hall door 2, since the number of teeth of the transmission gear plate 10 is greater than the number of teeth of the driving gear 6, the opening and closing door 5 can be completely closed before the hall door 2 is closed, thereby effectively preventing passengers from squeezing into the elevator during the closing process of the hall door 2, thereby achieving the effect of improving the safety of the elevator.

[0031] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the staggered mechanism 8 includes a positioning groove 81, and the positioning groove 81 is opened on the bottom side of the driving gear 6. There are eight positioning grooves 81, and the positioning grooves 81 are arranged in a circular array according to the axis of the driving gear 6. An elastic support rod 82 is arranged inside the positioning groove 81, and one end of the elastic support rod 82 extending out of the positioning groove 81 is arranged in an arc shape.

[0032] In this embodiment, the positioning groove 81 is provided for installing an elastic support rod 82, one end of which is fixedly connected to the inner groove wall of the positioning groove 81, and the elastic support rod 82 is a spring telescopic rod. The arc-shaped end of the elastic support rod 82 is pushed out of the positioning groove 81 by the elastic force of the elastic support rod 82, so that the arc-shaped end contacts the outer wall of the rotating shaft 4.

[0033] In a further preferred embodiment of the present invention, Figure 1-5 As shown, an arc-shaped stopper 83 is fixedly installed at a position on the outer surface of the rotating shaft 4 corresponding to the positioning groove 81 , and eight arc-shaped stoppers 83 are provided and arranged in a circular array according to the axis of the rotating shaft 4 .

[0034] In this embodiment, when in use, the arc-shaped end of the elastic support rod 82 is stuck in the position between the two arc-shaped blocks 83. At this time, when the driving gear 6 rotates, the elastic support rod 82 is locked by the arc-shaped block 83, thereby achieving the effect of driving the rotating shaft 4 to rotate. When the opening and closing door 5 contacts the door frame 1, the resistance encountered by the opening and closing door 5 is greater than the elastic force of the elastic support rod 82. Therefore, when the hall door 2 continues to drive the driving gear 6 to rotate through the linkage gear 61, the elastic support rod 82 will contract, so that the rotation between the driving gear 6 and the rotating shaft 4 is staggered, that is, the driving gear 6 rotates while the rotating shaft 4 does not rotate, thereby achieving the effect of allowing the hall door 2 to continue to unfold while the opening and closing door 5 is in a stagnant state.

[0035] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the positioning bracket 7 includes a rotating cylinder 71, and the rotating cylinder 71 is rotatably connected to the driving gear 6, and the axis lines of the rotating cylinder 71 and the driving gear 6 are on the same straight line. An extension rod 72 is fixedly connected to one side of the rotating cylinder 71, and the extension rod 72 is fixedly connected to the door frame 1.

[0036] In this embodiment, the rotating cylinder 71 is provided to install the driving gear 6, and the rotating cylinder 71 is fixed by the extension rod 72 to improve the stability of the driving gear 6 during rotation.

[0037] In a further preferred embodiment of the present invention, Figure 1-5As shown, a guide rail 11 is provided on the side of the opening and closing door 5 close to the hall door 2, a guide circular groove 12 is provided on the side of the guide rail 11 close to the hall door 2, a guide ball 13 is slidably provided inside the guide circular groove 12, and the guide ball 13 is fixedly connected to the hall door 2.

[0038] In this embodiment, by setting the guide rail 11 and the guide circular groove 12, when the hall door 2 is opened to a small extent, the guide ball 13 is located inside the guide circular groove 12. At this time, the hall door 2 and the opening and closing door 5 are fixed to each other. At this time, the opening and closing door 5 is subjected to resistance, and the driving gear 6 rotates alone with the hall door 2. After the hall door 2 is gradually opened, the guide ball 13 is separated from the guide circular groove 12. Figure 3 At this time, the hall door 2 continues to move, and the opening and closing door 5 will not be fixed by the guide circular groove 12 and the guide ball 13, and thus the opening and closing door 5 will not be subject to resistance. Therefore, the movement of the hall door 2, in conjunction with the linkage gear 61 and the driving gear 6, achieves the effect of controlling the rotation of the opening and closing door 5;

[0039] In summary, by setting the guide groove 12 and the guide ball 13, the opening and closing door 5 has an opening delay relative to the hall door 2 during the process from closing to opening, and the opening speed of the opening and closing door 5 is slower than that of the hall door 2, thereby preventing passengers from squeezing into the elevator when the hall door 2 is not fully opened.

[0040] In a further preferred embodiment of the present invention, Figure 1-5 As shown, a parallel groove 14 is provided at a position of the inner wall of the door frame 1 corresponding to the opening and closing door 5 .

[0041] In this embodiment, the parallel groove 14 is provided to store the opening and closing door 5 after the opening and closing door 5 is opened, so that the opening and closing door 5 and the door frame 1 form a plane to avoid blocking the elevator door.

[0042] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
