[0002] An elevator is a permanent transportation device that serves several specific floors in a building and whose car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or inclined at an angle of less than 15° to the plumb line. There are also step-type ones, where the treads are installed on the tracks and run continuously, commonly known as escalators or moving walkways. The elevator hall door upper sill frame commonly used in the prior art is made of plates bent at right angles. Since the elevator shaft wall may be uneven, during installation, in order to make the two right-angled sides of the hall door upper sill frame fit the elevator shaft wall and the hall door upper sill respectively, and at the same time ensure the verticality of the hall door upper sill, the upper sill frame can only be deformed by knocking to achieve the requirement of adjusting the verticality of the hall door upper sill.

The provided elevator hall door sill mounting bracket can cope with shaft walls of different flatness, shortening the adjustment time during installation of the elevator hall door sill;

[0004] However, the above device still has the following problems during implementation:

[0005] The upper sill frame in the above technical solution can cope with shaft walls of different flatness and shorten the adjustment time when installing the upper sill of the elevator hall door. However, considering that the environment for installing the upper sill frame is inside the shaft wall, the space inside the shaft wall itself is narrow, and the method of adjusting by rotating the positioning bolts still requires the use of tools, which is not conducive to user use and reduces the practicality of the upper sill frame. At the same time, the sizes of the hall doors are different, and the support area of ​​the upper sill frame is generally fixed, and the size of the support area cannot be adjusted according to actual conditions.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0034] See also Figure 1-Figure 8 , the utility model provides a technical solution:

[0035] Embodiment 1:

[0036] An adjustable elevator hall door upper sill frame comprises a first mounting plate 1 and a second mounting plate 2, the second mounting plate 2 is rotatably connected to the first mounting plate 1 through a rotating shaft, both sides of the second mounting plate 2 are fixedly connected with a rotating rod 3, both sides of the first mounting plate 1 are provided with a rotating hole 4 used in conjunction with the rotating rod 3, one end of the rotating rod 3 is fixedly connected with a shell 5, and an adjusting mechanism is arranged inside the shell 5, which can adjust the angle of the upper sill frame according to the hoistway wall with different flatness;

[0037] The extension mechanism is fixedly arranged on the first mounting plate 1 and can expand the area supported by the upper ledge.

[0038] One implementation of the present embodiment is: the adjustment mechanism includes a pulling block 6 movably arranged on one side of the shell 5, one side of the pulling block 6 is fixedly connected to a pulling rod 7, one end of the pulling rod 7 passes through the interior of the shell 5 and is fixedly connected to a moving block 8, one side of the moving block 8 is fixedly connected to four positioning rods 9, and both sides of the first mounting plate 1 are provided with a plurality of positioning holes 10 used in conjunction with the positioning rods 9.

[0039] In this embodiment, it is considered that the environment in which the upper sill frame is installed is inside the well wall, and the space inside the well wall itself is narrow. The method of adjusting by rotating the positioning bolts also requires the use of tools, which is not conducive to the use of users and reduces the practicality of the upper sill frame. Therefore, by setting an adjustment mechanism, the two pulling blocks 6 can be pulled to drive the pulling rod 7, the moving block 8 and the positioning rod 9 to move, so that the positioning rod 9 leaves the inside of the positioning hole 10. At this time, the second mounting plate 2 is not restricted and can be rotated and adjusted around the position of the rotating shaft and the rotating rod 3. After reaching the appropriate position, the pulling block 6 is released, and the spring 22 generates elastic force to push the moving block 8 and the four positioning rods 9 to move, so that the four positionings enter the corresponding positioning holes 10, and the adjustment of the upper sill frame can be completed;

[0040] The problem that the upper ledge frame is installed in the well wall, where the space is narrow, and the method of adjusting by rotating the positioning bolts requires the use of tools, which is not conducive to the use of the user and reduces the practicality of the upper ledge frame is solved;

[0041] It should be noted that the four positioning rods 9 are distributed in a ring shape, which disperses the force support points and can significantly improve the stability of the restriction.

[0042] Preferably, a spring 22 is sleeved on the surface of the pulling rod 7 , one end of the spring 22 is fixedly connected to one side of the moving block 8 , and the other end of the spring 22 is fixedly connected to the inner wall of the housing 5 .

[0043] In this embodiment, the spring 22 is provided so that when the pulling block 6 is released, the spring 22 generates elastic force to push the moving block 8 and the four positioning rods 9 to move, thereby resetting the structures such as the moving block 8 and the positioning rods 9.

[0044] Embodiment 2:

[0045] On the basis of Example 1, the adjustment mechanism in this embodiment can facilitate the adjustment of the angle of the upper sill frame, but considering the different sizes of the hall doors, the support area of ​​the upper sill frame is generally fixed in size and the size of the support area cannot be adjusted according to actual conditions. The extension mechanism in this application includes a telescopic groove 11 opened on one side of the second mounting plate 2, and the interior of the telescopic groove 11 is slidably connected to a telescopic block 12, and one side of the telescopic block 12 is fixedly connected to an extension plate 13, and both sides of the inner wall of the telescopic groove 11 are provided with matching grooves 14.

[0046] The extension mechanism also includes a stop block 15 arranged inside the matching groove 14, and a threaded rod 16 is fixedly connected to one side of the stop block 15. One end of the threaded rod 16 passes through one side of the second mounting plate 2 and is fixedly connected to a twisting block 17. A threaded hole 18 for use with the threaded rod 16 is opened on one side of the second mounting plate 2.

[0047] In this embodiment, the sizes of the hall doors are different, and the support area of ​​the upper sill frame is generally fixed, and the size of the support area cannot be adjusted according to the actual situation. Therefore, by setting an extension mechanism, the two twisting blocks 17 can be rotated to drive the threaded rod 16 to rotate inside the threaded hole 18, so that the threaded rod 16 gradually moves to the outside of the second mounting plate 2, and at the same time drives the abutting block 15 and the friction block 19 to retract into the matching groove 14, contacting the restriction of the telescopic block 12, and then the extension plate 13 and the telescopic block 12 can be pulled to expand along the trajectory of the sliding block 20 and the sliding groove 21, effectively increasing the support area of ​​the upper sill frame;

[0048] The invention solves the problem that the supporting area of ​​the upper sill frame is generally of a fixed size and the size of the supporting area cannot be adjusted according to the actual situation, taking into account the different sizes of the hall doors.

[0049] Preferably, a friction block 19 is fixedly connected to one side of the abutting block 15 , so as to increase the friction force after the abutting block 15 contacts the extension plate 13 .

[0050] In this embodiment, the friction block 19 is provided to increase the friction force after the abutting block 15 contacts the extension plate 13 , thereby preventing the telescopic block 12 from being unstable after being extended and abutted by the abutting block 15 , resulting in retraction.

[0051] Preferably, the top and the bottom of the telescopic block 12 are fixedly connected with a sliding block 20 , and the inner wall of the telescopic slot 11 is provided with a sliding slot 21 used in conjunction with the sliding block 20 .

[0052] In this embodiment, by providing the sliding block 20 and the sliding groove 21 , the moving track of the telescopic block 12 can be limited so that the telescopic block 12 can only move along the moving track of the telescopic block 12 .

[0053] Working principle: The user pulls the two pulling blocks 6 to drive the pulling rod 7, the moving block 8 and the positioning rod 9 to move, so that the positioning rod 9 leaves the inside of the positioning hole 10. At this time, the second mounting plate 2 is no longer restricted and can be rotated and adjusted around the rotation axis and the position of the rotating rod 3. After reaching the appropriate position, the pulling block 6 is released, and the spring 22 generates elastic force to push the moving block 8 and the four positioning rods 9 to move, so that the four positioning rods enter the corresponding positioning holes 10, and the angle adjustment of the upper ledge can be completed;

[0054] At the same time, taking into account the different sizes of hall doors, and the support area of ​​the upper sill frame is generally fixed in size, it is impossible to adjust the size of the support area according to actual conditions. Therefore, by setting an extension mechanism, the two twisting blocks 17 can be rotated to drive the threaded rod 16 to rotate inside the threaded hole 18, so that the threaded rod 16 gradually moves to the outside of the second mounting plate 2, and at the same time drives the abutting block 15 and the friction block 19 to retract into the matching groove 14, contacting the restriction on the telescopic block 12, and then the extension plate 13 and the telescopic block 12 can be pulled to expand along the trajectory of the sliding block 20 and the sliding groove 21, effectively increasing the support area of ​​the upper sill frame.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
