Description

Technical Field

[0001] This application relates to the technical field of security doors, and specifically to a lifting mechanism for a security door. Background Art

[0002] A lifting security door is a device used to control and protect the safe operation of lifting equipment such as elevators and lifting platforms.

[0003] After retrieval, the publication number is CN220353716U, which discloses a hydraulic lifting security door, including a door frame, and also including a door body, a guiding door rail assembly, a lifting assembly, and a safety assembly. The guiding door rail assembly includes two oppositely arranged guiding sliding rails. Both guiding sliding rails are arranged along the height direction of the door frame and are respectively installed on the two inner sides of the door frame. The two sides of the door body are respectively in sliding fit with the corresponding guiding sliding rails on the corresponding sides. The lifting assembly includes a lifting member fixed on the guiding sliding rail. The lifting member is fixedly connected to the door body and is used to push the door body to move along the height direction of the door frame. The safety assembly is used to support the upper and lower parts of the door body after lifting in place respectively, and solves the technical problems of difficult opening and closing of heavy doors and potential safety hazards by setting the lifting member and the safety assembly.

[0004] However, the existing security door lifting uses a cylinder to drive the security door body, and uses a linear optical axis and a linear bearing for guiding. The optical axis is fixed on the frame, and the slider moves up and down with the door. It is difficult to ensure the parallelism of the optical axis of this mechanism, resulting in great difficulty in installation and debugging.

[0005] Therefore, it is necessary to provide a lifting mechanism for a security door to solve the above problems.

[0006] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute the prior art. Utility Model Content

[0030] In order to enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the protection scope of this application.

[0031] Please refer to Figures 1-5 , the embodiments provided by the present utility model:

[0032] A safety door lifting mechanism includes a front door panel 1 and a front door stopper 2. Both sides of the front door panel 1 are slidably connected to the front door stopper 2 through a lifting mechanism. A surrounding plate 3 is provided outside the lifting mechanism. The surrounding plate 3 is fixedly installed on both sides of the front door stopper 2. Through the surrounding plate 3, the lifting mechanism can be surrounded on both sides of the front door stopper 2 to avoid being exposed. The lifting mechanism includes a driving component 4, a sliding component 5 and a mounting frame 6. One side of the mounting frame 6 is fixedly installed on both sides of the front door panel 1 respectively, and the other side of the mounting frame 6 is fixedly installed with the sliding component 5. The sliding component 5 moves up and down on one side of the driving component 4. The driving component 4 includes a fixed frame and a cylinder 42. The cylinder 42 is installed on the inner bottom surface of the fixed frame, and the end of the telescopic shaft rod of the cylinder 42 is fixedly installed on the top of the mounting frame 6.

[0033] The fixed frame includes a bottom plate 41, support arms 43 and a top plate 44. Both sides of the top surface of the bottom plate 41 are fixedly installed with the bottom ends of the support arms 43 respectively. The top ends of the support arms 43 are fixedly installed with both sides of the bottom surface of the top plate 44. The side wall of the bottom plate 41 is fixedly installed on both sides of the front door stopper 2.

[0034] By the extension or shortening of the telescopic shaft rod of the cylinder 42 on the bottom plate 41, the mounting frame 6 is driven to move up and down, so that the front door panel 1 can move up and down above the front door stopper 2, and thus the lifting of the front door panel 1 can be adjusted.

[0035] Specifically, mounting plates 12 are fixedly connected to both sides of the front door panel 1 respectively. The side walls of the mounting plates 12 are fixedly installed with the mounting frame 6 through screws. The mounting frame 6 includes a frame 61, a shaft seat 62 and a clamping seat 63. The side wall of the mounting plate 12 is fixedly installed with one side of the frame 61 through screws. A shaft seat 62 is fixedly installed at the top of the other side of the mounting frame 6. The bottom end of the shaft seat 62 is fixedly installed with the end of the telescopic shaft rod of the cylinder 42. Clamping seats 63 are fixedly installed on the side walls of the other side of the mounting frame 6 respectively. By adjusting the mounting position between the mounting plate 12 and the frame 61, the mounting distance between the front door panel 1 and the front door stopper 2 can be adjusted, so as to facilitate the position debugging of the front door panel 1 after installing the safety door.

[0036] The sliding component 5 includes linear bearings 51 and linear optical shafts 52. The linear bearings 51 are symmetrically installed on the bottom surface of the top plate 44 with the cylinder 42 as the axis. The linear optical shafts 52 are slidably connected inside the linear bearings 51. Both ends of the two linear optical shafts 52 are fixedly installed inside the clamping seats 63.

[0037] During the process of the cylinder 42 driving the frame 61 to move up and down, through the up and down sliding of the linear optical shafts 52 inside the linear bearings 51, the front door panel 1 installed with the frame 61 can move parallelly during the lifting process, so that the lifting of the safety door is more stable.

[0038] A baffle 11 is provided on the inner side wall at the bottom of the front door panel 1, and a relief groove 21 is provided on the inner side of the front door stopper 2. When the front door panel 1 approaches the front door stopper 2, the baffle 11 can be placed in the relief groove 21, so as to further reduce the gap generated between the front door panel 1 and the front door stopper 2 after being closed.

[0039] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
