[0052] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0053] See also Figure 1-Figure 18 The present invention provides a fastened adjustable curved elevator glass door, which is installed at the opening of a cylindrical elevator car 1. The elevator car 1 includes a columnar ceiling bracket 11, a chassis 12, and a plurality of support rods 13 for connecting the columnar ceiling bracket 11 and the chassis 12.

[0054] Combination Figure 1 and Figure 3The fastening type adjustable curved elevator glass door comprises a pair of arc-shaped tempered glasses 3 symmetrically slidably mounted at the opening of the elevator car 1, a pair of upper fasteners 4 detachably mounted on the top of the arc-shaped tempered glasses 3, and a pair of lower fasteners 41 detachably mounted on the bottom of the arc-shaped tempered glasses 3; the upper fasteners 4 are connected to a sliding mechanism 5 that is slidably matched with the columnar ceiling bracket 11, and the sliding mechanism 5 is used to drive the pair of upper fasteners 4 to slide relative to or opposite to each other on the columnar ceiling bracket 11 around the central axis of the elevator car 1; the lower fasteners 41 are connected to a clamping column 6 that is slidably matched with the chassis 12.

[0055] The present invention eliminates the elevator door frame in the conventional technology and adopts a pair of frameless arc-shaped tempered glass 3 as the elevator door, so that the elevator has higher transparency and better lighting effect.

[0056] As for the installation of the arc-shaped tempered glass 3, after the present invention installs a pair of upper fasteners 4 on the top of the arc-shaped tempered glass 3, the arc-shaped tempered glass 3 is slidably assembled on the columnar ceiling bracket 11 through the connection with the sliding mechanism 5; and after the pair of lower fasteners 41 are installed at the bottom of the arc-shaped tempered glass 3, the clamping columns 6 of the lower fasteners 41 are slidably connected with the slideway provided on the chassis 12, so that the pair of frameless arc-shaped tempered glasses 3 can slide smoothly at the opening of the elevator car 1 to complete the door opening and closing action.

[0057] Specifically, Figure 8 As shown, a pair of mounting holes 31 are provided at the four corners of the arc-shaped tempered glass 3, and the pair of mounting holes 31 are distributed longitudinally;

[0058] like Figure 5 and 6 As shown, the upper fastener 4 and the lower fastener 41 have the same structure, both including a mounting block 42 and a first clamping body 43 and a second clamping body 44 arranged on one side of the mounting block 42, wherein the first clamping body 43 is formed with a first clamping surface 431 on one side relative to the second clamping body 44, and the second clamping body 44 is formed with a second clamping surface 441 parallel to the first clamping surface 431 on one side relative to the first clamping body 43; a pair of columnar protrusions 45 vertically protruding toward the first clamping surface 431 are formed on the second clamping surface 441, and the pair of columnar protrusions 45 are adapted to the pair of mounting holes 31, and a countersunk hole 442 coaxial with the columnar protrusion 45 is penetrated at the position of the columnar protrusion 45 of the second clamping body 44; an internal threaded hole 432 (such as Figure 8As shown); one end of the first clamping body 43 is fixedly connected to the mounting block 42, and one end of the second clamping body 44 forms a detachable sliding connection structure with the mounting block 42 through a keyway structure, and the second clamping body 44 can only slide on the mounting block 42 in a direction perpendicular to the first clamping surface 431 through the keyway.

[0059] like Figure 8 As shown, during installation, a pair of columnar protrusions 45 of the second clamping body 44 are inserted into a pair of mounting holes 31 corresponding to the arc-shaped tempered glass 3 until the second clamping surface 441 of the second clamping body 44 contacts the arc-shaped tempered glass 3, and then the first clamping body 43 is moved to make the second clamping body 44 correspond to the keyway structure of the mounting block 42, thereby completing the combination of the first clamping body 43 and the second clamping body 44. After the combination, it is only necessary to pass the bolts through the countersunk holes 442 and threadedly connect them to the internal threaded holes 432 to complete the connection between the arc-shaped tempered glass 3 and the upper fastener 4 or the lower fastener 41.

[0060] The upper fastener 4 and the lower fastener 41 of the present invention have a simple structure and are easy to install, which is beneficial to improving the assembly efficiency of the elevator door. After the upper fastener 4 and the lower fastener 41 are connected to the arc-shaped tempered glass 3, they can be clamped by the columnar protrusion 45, the first clamping surface 431 and the second clamping surface 441 to ensure the reliable connection between the upper fastener 4 and the lower fastener 41 and the arc-shaped tempered glass 3, thereby ensuring the stability of the door opening and closing process of a pair of frameless arc-shaped tempered glasses 3.

[0061] In addition, this installation method eliminates the elevator door frame in conventional technology, and the upper fastener 4 and the lower fastener 41 are connected to the arc-shaped tempered glass 3. During the assembly process, not only the arc-shaped tempered glass 3 can be adjusted front and back, but also the arc-shaped tempered glass 3 can be adjusted left and right, thereby facilitating the assembly of the elevator door.

[0062] like Figure 5 and Figure 6 As shown, in a specific embodiment of the present invention, a first arc surface 433 is formed on the side of the first clamping body 43 away from the second clamping body 44, a second arc surface 443 is formed on the side of the second clamping body 44 away from the first clamping body 43, and a semi-circular arc convex head is formed on one end of the first clamping body 43 and the second clamping body 44 away from the mounting block 42. Based on the above design, after the present invention is installed, the exterior of the first clamping body 43 and the second clamping body 44 is a smooth structure, which can improve the overall aesthetics.

[0063] Please continue reading Figure 5 and Figure 6In a specific embodiment of the present invention, the mounting block 42 is provided with a slide groove 421 perpendicular to the first clamping surface 431 at the position corresponding to the second clamping body 44, and a sliding portion 444 adapted to the slide groove 421 is formed at one end of the second clamping body 44 close to the mounting block 42, and a handle is formed by extending along a direction perpendicular to the second clamping surface 441 at one end of the sliding portion 444 away from the second clamping surface 441, and the handle and the second clamping body 44 form an L-shaped structure. Based on the above design, the cooperation between the sliding portion 444 of the second clamping body 44 and the slide groove 421 on the mounting block 42 can facilitate the combination of the first clamping body 43 and the second clamping body 44 (that is, the countersunk hole 442 on the second clamping body 44 corresponds to the internal threaded hole 432 of the first clamping body 43), and the handle formed by the sliding portion 444 can facilitate the staff to grasp during the installation process so as to complete the connection work of the first clamping body 43 and the second clamping body 44.

[0064] In a specific embodiment of the present invention, the first clamping surface 431 and the second clamping surface 441 are both provided with a rubber anti-skid pad 46. Based on the above design, the provision of the rubber anti-skid pad 46 can, on the one hand, prevent the first clamping body 43 and the second clamping body 44 from making hard contact with the arc-shaped tempered glass 3, thereby preventing damage to the arc-shaped tempered glass 3; on the other hand, the rubber anti-skid pad 46 can be deformed to increase the contact area with the arc-shaped tempered glass 3, thereby improving the stability of the connection between the upper fastener 4 or the lower fastener 41 and the arc-shaped tempered glass 3.

[0065] like Figure 1 and Figure 4 As shown, in a specific embodiment of the present invention, the sliding mechanism 5 includes a circular track 51 coaxially mounted on the top of the columnar ceiling bracket 11, a slider assembly 52 slidably arranged on the circular track 51, and a movable connecting assembly 53 fixedly mounted on one of the slider assemblies 52 of the arc-shaped tempered glass 3; the slider assembly 52 includes a sliding block 521 slidably mounted on the circular track 51 and a connecting sheet metal 522 for connecting the sliding block 521 and the upper fastener 4; a pair of movable connecting assemblies 53 of the arc-shaped tempered glass 3 are respectively connected to a pair of swing arms 2 of the elevator door machine driving device (not shown), so that the pair of arc-shaped tempered glass 3 forms a coaxial reversing door opening and closing structure around the central axis of the elevator car 1. The elevator door machine driving device is a prior art, and its specific structure and principle are not elaborated too much here.

[0066] Since the present invention uses a pair of frameless arc-shaped tempered glass 3 as the elevator door, when the elevator door is closed, the side edges of the pair of arc-shaped tempered glass 3 will contact and abut against each other. During this process, the contact and abutment of the pair of arc-shaped tempered glass 3 is a hard contact. If at this time, the swing speed of the pair of swing arms 2 of the elevator door machine drive device is too high, the pair of arc-shaped tempered glass 3 will be damaged due to excessive impact force when the opposite sides contact, shortening its service life. For this reason, if Figure 4 As shown, in a specific embodiment of the present invention, the movable connection component 53 includes an arc plate 531, a driving connection member 532 and a deceleration driving member 533, wherein the arc plate 531 is fixedly assembled on the top of the sliding block 521, and an arc deceleration groove 5311 is provided through the arc plate 531, the center of the arc deceleration groove 5311 is on the central axis of the elevator car 1, the two ends of the arc deceleration groove 5311 are respectively a starting end 5311a and an end 5311b, and the end 5311b is close to the side of the door closing direction, the driving connection member 532 is fixedly connected to the swing arm 2 of the elevator door machine driving device, and the driving connection member 532 is slidably adapted in the arc deceleration groove 5311;

[0067] Combination Figure 4 and Figure 16-Figure 19 As shown, the process of the swing arm 2 swinging and driving the arc-shaped tempered glass 3 to close the door includes a first stroke and a second stroke; in the first stroke, the driving connection member 532 is at the starting end 5311a of the arc deceleration groove 5311, and in the second stroke, the deceleration driving member 533 is used to drive the driving connection member 532 to move relative to the arc plate 531 in the arc deceleration groove 5311 toward the end 5311b; when the swing arm 2 stops swinging, the deceleration driving member 533 drives the driving connection member 532 to move slowly relative to the arc plate 531 in the arc deceleration groove 5311 toward the starting end 5311a until the driving connection member 532 moves to the starting end 5311a of the arc deceleration groove 5311, completing the door closing action.

[0068] Based on the above design, in the first stroke, the driving connection member 532 is limited by the deceleration driving member 533 and is at the starting end 5311a of the arc deceleration groove 5311, the arc plate 531 and the driving connection member 532 are relatively fixed, the driving connection member 532, the arc plate 531 and the sliding block 521 are equivalent to an integrated structure, and the moving speed of the driving connection member 532 driven by the pair of swing arms 2 is adapted to the moving speed of the pair of arc-shaped tempered glasses 3;

[0069] When the arc-shaped tempered glass 3 moves to the second stroke, the distance between the pair of arc-shaped tempered glasses 3 is smaller, but the two are not in contact. At this time, the slow-speed driving member 533 drives the driving connecting member 532 to move relative to the arc plate 531 in the arc slow-speed groove 5311 toward its end 5311b. It can be understood that if the driving connecting member 532 is regarded as a stationary reference object, the arc plate 531 will move relative to the driving connecting member 532 toward the door opening. However, since the driving connecting member 532 is driven by the swing arm 2 to maintain the original speed at this time, the moving speed of the driving connecting member 532 driven by the pair of swing arms 2 is greater than the moving speed of the pair of arc-shaped tempered glasses 3. That is, the moving speed of the arc plate 531 slows down relative to the moving speed of the driving connection member 532, that is, the moving speed of the arc-shaped tempered glass 3 slows down; when the swing arm 2 stops moving, there is still a gap between the pair of arc-shaped tempered glasses 3 (the gap is the relative moving distance between the driving connection member 532 and the arc plate 531). At this time, the slow-moving driving member 533 drives the driving connection member 532 to move slowly toward the starting end 5311a in the arc slow-moving groove 5311 relative to the arc plate 531, that is, the arc plate 531 maintains the previous slow moving speed and moves relative to the driving connection member 532 in the door closing direction, completing the door closing action of the pair of arc-shaped tempered glasses 3 contacting and abutting against each other.

[0070] The design of the above structure of the present invention allows the pair of arc-shaped tempered glasses 3 to move slowly at a speed lower than the original door opening and closing speed when they are about to touch, without affecting the swing of the swing arm 2, so as to avoid excessive impact when the pair of arc-shaped tempered glasses 3 touch, resulting in damage to the opposite sides of the pair of arc-shaped tempered glasses 3 and shortening their service life.

[0071] It should be noted that, during the door opening process, the moving speed of the pair of arc-shaped tempered glasses 3 will not change, that is, the door opening speed will not be reduced, which can reduce the waiting time of the user.

[0072] In order to improve the stability of the opening and closing of a pair of arc-shaped tempered glass doors 3 and reduce the installation of drive components and detection device circuits. Figure 4 , Fig.11 , Fig.13 As shown, in a specific embodiment of the present invention, the deceleration drive member 533 includes a preload spring 5331 fixedly assembled between the driving connection member 532 and the end 5311b of the circular arc deceleration groove 5311, a first hydraulic telescopic cylinder 5332 arranged on the side of the driving connection member 532 away from the preload spring 5331, a second hydraulic telescopic cylinder 5333 fixed at the bottom of the circular arc plate 531, and a trigger member 5334 (such as Figure 7 shown);

[0073] like Fig.11 and Fig.13As shown, the telescopic end of the first hydraulic telescopic cylinder 5332 is rotatably connected to the driving connection member 532, the fixed end of the first hydraulic telescopic cylinder 5332 is rotatably connected to the arc plate 531, and the second hydraulic telescopic cylinder 5333 is connected to the first hydraulic telescopic cylinder 5332 through an oil pipe; the second hydraulic telescopic cylinder 5333 is arranged along the radial direction of the elevator car 1, and the inner diameter of the oil chamber of the second hydraulic telescopic cylinder 5333 is smaller than the inner diameter of the oil chamber of the first hydraulic telescopic cylinder 5332;

[0074] like Fig.13 , Fig.15 and Fig.16 The trigger member 5334 includes a guide block 53341 fixed to the telescopic end of the second hydraulic telescopic cylinder 5333 and a stopper column 53342 fixed to the columnar ceiling bracket 11 and corresponding to the guide block 53341; the guide block 53341 is provided with an inclined surface 533411 on the side close to the door closing direction, the bottom end of the stopper column 53342 is rotatably provided on the columnar ceiling bracket 11 through a hinge seat 53344, the hinge seat 53344 is provided with a limit block 53343 for limiting the rotation of the stopper column 53342 in the door closing direction, the hinge axis of the stopper column 53342 is provided along the radial direction of the elevator car 1, and a torsion spring (not shown) is provided on the hinge axis of the stopper column 53342;

[0075] When the swing arm 2 swings to drive the arc-shaped tempered glass 3 to reach the second stroke and move, the inclined surface 533411 of the guide block 53341 contacts the stop column 53342 to enable the guide block 53341 to move toward the second hydraulic telescopic cylinder 5333. When the swing arm 2 stops swinging, the guide block 53341 just disengages from the stop column 53342.

[0076] like Fig.14 As shown, a one-way damping plate 5335 is provided in the first hydraulic telescopic cylinder 5332 , and tapered holes 53351 are evenly penetrated through the one-way damping plate 5335 , and the small end of the tapered hole 53351 faces the rod cavity side of the first hydraulic telescopic cylinder 5332 .

[0077] Based on the above design, Figure 16-Figure 17 In the door closing action shown, in the first stroke, the elastic force preloaded by the preload spring 5331 can cause the driving connector 532 to limit the starting end 5311a of the arc deceleration groove 5311, thereby making the rotation speed of the swing arm 2 correspond to the moving speed of the arc-shaped tempered glass 3;

[0078] When the arc-shaped tempered glass 3 moves to the second stroke (refer to Fig.17As shown in the figure, the inclined surface 533411 of the guide block 53341 contacts the stop column 53342. As the swing arm 2 swings, the inclined surface 533411 of the guide block 53341 contacts the outer peripheral surface of the stop column 53342, which can make the guide block 53341 move toward the second hydraulic telescopic cylinder 5333, thereby shortening the second hydraulic telescopic cylinder 5333 and introducing its internal hydraulic oil into the first hydraulic telescopic cylinder 5332 through the oil pipe, so that the first hydraulic telescopic cylinder 5332 extends. The extension of the first hydraulic telescopic cylinder 5332 will cause the arc plate 531 to move relative to the driving connecting piece 532 in the door opening direction, thereby slowing down the moving speed of the arc-shaped tempered glass 3. When the swing arm 2 stops swinging (refer to Fig.18 As shown in the figure, at this time, the guide block 53341 is just separated from the blocking column 53342. Under the elastic force of the preload spring 5331, the arc plate 531 moves relative to the driving connecting member 532 (the driving connecting member 532 is stationary at this time) in the door closing direction. However, since a one-way damping plate 5335 is provided in the first hydraulic telescopic cylinder 5332, and the small end of the conical hole 53351 uniformly penetrated on the one-way damping plate 5335 faces the rod cavity side of the first hydraulic telescopic cylinder 5332 ( Fig.14 ), under the damping of the oil, the arc plate 531 maintains the previous slow moving speed and moves relative to the driving connecting member 532 in the door closing direction, completing the door closing action of a pair of arc-shaped tempered glasses 3 contacting and abutting against each other (refer to Figure 18-19 ).

[0079] like Fig.14 As shown, in a specific embodiment of the present invention, the first hydraulic telescopic cylinder 5332 and the second hydraulic telescopic cylinder 5333 each include a hydraulic cylinder 53321, a piston 53322 slidably disposed in the hydraulic cylinder 53321, and a movable rod 53323 coaxially disposed on the piston 53322.

[0080] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
