[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1

[0028] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a gap handling mechanism for a large theater lifting stage. The gap handling mechanism for a large theater lifting stage includes a stage component 100 and an anti-pinch component 200. The anti-pinch component 200 plays a protective and anti-pinch role during the rising and falling of the stage component 100, avoiding accidents such as clothing being pinched during the performance.

[0029] Specifically, the stage assembly 100 includes a base plate 101, a lifting component 102, a platform 103, and a railing 104. The lifting component 102 is located on both sides of the top of the base plate 101, the platform 103 is fixed to the top of the lifting component 102, and the railing 104 is fixed to the top of the base plate 101 and located outside the platform 103.

[0030] The lifting component 102 can be a hydraulic telescopic rod, a Z-shaped lifting component, or an X-shaped lifting component, etc. This is existing technology and will not be described in detail here. The fence 104 is rectangular, and the lifting component 102 is located inside it to protect it and prevent the lifting component 102 from being damaged by external impacts during use.

[0031] The anti-pinch component 200 is installed on the fence 104 and includes a protective frame 201, a lifting component 202, a driving component 203, and a movable door 204. The protective frame 201 is located at the top of the fence 104 and has a sliding groove S at its bottom. The fence 104 slides in the sliding groove S. The lifting component 202 is installed on both sides of the fence 104. The driving component 203 is installed on the fence 104 and cooperates with the lifting component 202. An exit K is opened on one side of the protective frame 201 and the movable door 204 is installed in the exit K.

[0032] The protective frame 201 is rectangular, and the edge of the platform 103 fits against the inner wall of the protective frame 201. That is, when the platform 103 slides up and down inside the protective frame 201, there are no gaps between the platform 103 and the protective frame 201, or between the platform 103 and the stage surface, thus avoiding situations such as actors' clothing getting caught during the lifting process. The lifting component 202 and the driving component 203 make the lifting of the protective frame 201 more convenient. Furthermore, the movable door 204 and the exit K facilitate actors getting on and off the platform 103.

[0033] Example 2

[0034] Reference Figures 2-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, the anti-pinch component 200 also includes a limiting block 205, which is fixed to both sides of the inner wall of the outlet K and contacts the movable door 204.

[0036] The limiting block 205 is located near the outside of the movable door 204. When the movable door 204 opens inward, the limiting block 205 limits its opening to prevent it from accidentally opening outward during use and affecting its use.

[0037] The lifting component 202 includes a wing plate 202a, a top plate 202b, and a movable block 202c. The wing plate 202a is fixed to the bottom of both sides of the protective frame 201, the top plate 202b is located at the bottom of the wing plate 202a, the movable block 202c slides on both sides of the bottom of the base plate 101, and the top plate 202b is hinged to the top of the movable block 202c.

[0038] The wing plate 202a is rectangular, and its bottom contacts the end of the top plate 202b. When the ends of the two top plates 202b move upward, they can lift the wing plate 202a and the protective frame 201 upward, so that the top of the protective frame 201 contacts the bottom of the upper stage, and its inner wall fits the inner wall of the hole set in the upper stage. This ensures that the platform 103 will not have gaps during the above process, and the movable block 202c can move left and right, driving the top plate 202b to move.

[0039] The lifting component 202 also includes a fixed shaft 202d. The two top plates 202b are X-shaped and intersecting, and are rotatably connected by the fixed shaft 202d. Both sides of the fence 104 are provided with through holes J, and the end of the fixed shaft 202d slides in the through hole J.

[0040] The fixed shaft 202d is located at the intersection of the two top plates 202b. When the movable block 202c moves, the two top plates 202b will move with it. At the same time, the fixed shaft 202d will move up and down in the through hole J, so that the ends of the two top plates 202b will move up and down, thereby driving the protective frame 201 to move up and down.

[0041] The lifting component 202 also includes a fixed block 202e and a threaded rod 202f. The fixed block 202e is fixed to the top of the base plate 101 and is located outside the movable block 202c. The two ends of the threaded rod 202f are rotatably connected to the two fixed blocks 202e respectively, and are threadedly connected to the movable block 202c.

[0042] The fixed block 202e is rectangular, and the threaded rod 202f is connected to the fixed block 202e by a bearing. The threaded rods 202f on both sides have opposite thread directions, so that when the threaded rod 202f rotates, it can drive the two movable blocks 202c to move inward or outward at the same time, thereby driving the two top plates 202b to move.

[0043] The lifting component 202 also includes a guide plate 202g, which is fixed between two fixed blocks 202e. A guide hole M is provided on the movable block 202c, and the guide plate 202g slides in the guide hole M.

[0044] The guide plate 202g is rectangular. The guide plate 202g and the guide hole M limit the movement of the movable block 202c to prevent it from deviating during left and right movement.

[0045] Example 3

[0046] Reference Figures 1-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0047] Specifically, the drive component 203 includes a connecting shaft 203a, a worm gear 203b, and a turbine 203c. The connecting shaft 203a is rotatably connected to the fence 104. The worm gear 203b is fixed to both ends of the connecting shaft 203a and is located outside the fence 104. The turbine 203c is fixed to the middle of the threaded rod 202f and cooperates with the worm gear 203b.

[0048] The connecting shaft 203a passes through the fence 104, with its two ends extending from both sides of the fence 104. The connecting shaft 203a and the fence 104 are rotatably connected by bearings. When the connecting shaft 203a rotates, the worm gear 203b drives the turbine 203c to rotate, which in turn drives the threaded rod 202f to rotate, and then the threaded rod 202f drives the movable block 202c to move left and right.

[0049] The drive unit 203 also includes a rocker arm 203d, which is fixed to one end of the worm gear 203b.

[0050] The rocker arm 203d is Z-shaped. The design of the rocker arm 203d makes it easier for the operator to rotate the worm gear 203b and the connecting shaft 203a, thereby facilitating manual adjustment of the height of the protective frame 201.

[0051] The top of the movable door 204 is rotatably connected to the slide groove S via a hinge, and it rotates inward toward the protective frame 201.

[0052] The top of the platform 103 is located inside the fence 104, and the bottom of the movable door 204 is parallel to the top of the platform 103.

[0053] In use, the device is placed directly below the opening in the upper stage. Then, the rocker arm 203d is manually rotated. The rocker arm 203d drives the worm gear 203b and the connecting shaft 203a, which in turn drives the threaded rod 202f to rotate. At this time, the threaded rod 202f drives the movable block 202c to move inward, causing the tops of the two top plates 202b to move upward and lift the protective frame 201 until its top contacts the bottom of the upper stage. This removes the gap between the platform 103 and the stage opening. When the platform 103 moves upward, it will move along the inner wall of the protective frame 201, thus preventing the platform 103 from trapping the actors' clothing due to the gap during its ascent, greatly improving the operational safety of the platform 103.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
