Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary devices for folding door maintenance, and in particular to an auxiliary device for folding door maintenance. Background Technology
[0002] Folding doors are a type of door that connects multiple door panels with hinges and can be folded to one or both sides. They are space-saving and flexible in dividing areas. Compared with hinged doors, they save more than 50% of turning space and are suitable for narrow areas (such as balconies and storage rooms).
[0003] Existing folding doors require regular disassembly and maintenance after use. This includes lubricating the hinges used to connect the folding doors, or replacing the hinges depending on their wear. Since folding doors are generally large in size and often have glass embedded in their inner frames, the glass may break due to vibration if they are placed flat on the ground. However, it is difficult to maintain the stability of the folding door by supporting it. Therefore, we provide an auxiliary device for the maintenance of folding doors. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies where workers cannot continuously support the folding door upright during maintenance, and to provide an auxiliary device for folding door maintenance.

[0011] In a preferred embodiment, one end of the threaded post is provided with a rotating block, which is fixedly connected to the threaded post.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] This invention features a fixing mechanism that assists workers in maintaining disassembled folding doors, preventing them from tipping over or wobbling during folding. This allows workers to maintain the folding doors more conveniently and efficiently. A counterweight enhances the stability of the fixing mechanism's center of gravity. A clamping plate continuously approaches the folding door, pressing and securing it to maintain its stability.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1
[0022] like Figures 1-3 As shown, this utility model provides a technical solution: an auxiliary device for maintaining a folding door, comprising: a fixing mechanism 1, the fixing mechanism 1 including a counterweight 11, a limit plate 12 fixedly connected to the top of the counterweight 11, a support rod 13 fixedly connected to the bottom of the counterweight 11, a placement block 14 provided on one side of the support rod 13, the placement block 14 being fixedly connected to the support rod 13, a threaded rod 15 sleeved inside the counterweight 11, a threaded block 16 sleeved on the outer surface of the threaded rod 15, the threaded block 16 being threadedly connected to the threaded rod 15, a clamping plate 17 provided at one end of the threaded block 16, the clamping plate 17 being fixedly connected to the threaded block 16, and the clamping plate 17 being fixedly connected to the threaded block 16. A rubber pad 18 is provided on one side of the plate 17. The rubber pad 18 is fixedly connected to the clamp plate 17. Auxiliary mechanisms 2 are provided on both sides of the counterweight seat 11. The auxiliary mechanism 2 includes a connecting block 21. A threaded post 22 is sleeved inside the connecting block 21. A threaded block 16 is sleeved inside the counterweight seat 11. The threaded block 16 is slidably connected to the counterweight seat 11. A rotating plate 19 is provided at one end of the threaded rod 15. The rotating plate 19 is placed inside the counterweight seat 11. The rotating plate 19 is fixedly connected to the threaded rod 15. The rotating plate 19 is rotatably connected to the inner wall of the counterweight seat 11. A handle 101 is provided at one end of the threaded rod 15. The handle 101 is fixedly connected to the threaded rod 15.
[0023] In this embodiment, by setting a counterweight 11 and a limiting plate 12, the corners of the folding door can be placed, thus limiting the folding door. At the same time, a threaded rod 15 is set, which can drive the threaded block 16, allowing the threaded block 16 to reciprocate. Thus, the clamping plate 17, which is fixedly connected to the threaded block 16, can drive the rubber pad 18 to move towards the folding door. The clamping plate 17 and the rubber pad 18 can press and fix the folding door with the cooperation of the counterweight 11 and the limiting plate 12. In addition, the setting of the rubber pad 18 fills the gap between the clamping plate 17 and the folding door, so that the folding door will not shake when it is being maintained. The placement block 14 is set so that one of the worker's feet can be placed, so that the entire fixing mechanism 1 will not move when the worker turns the handle 101.
[0024] Example 2
[0025] like Figures 1-3As shown, the connecting block 21 is fixedly connected to the counterweight seat 11, the threaded column 22 is threadedly connected to the connecting block 21, one end of the threaded column 22 is provided with a pad 23, the pad 23 is fixedly connected to the threaded column 22, one side of the pad 23 is provided with an anti-slip pad 24, the anti-slip pad 24 is fixedly connected to the pad 23, one end of the threaded column 22 is provided with a rotating block 25, the rotating block 25 is fixedly connected to the threaded column 22.
[0026] In this embodiment, a connecting block 21 and a threaded post 22 are provided simultaneously, and the threaded post 22 is threadedly connected to the connecting block 21. Thus, the threaded post 22 can rotate and move with the cooperation of the connecting block 21. The pad 23, which is fixedly connected to the threaded post 22, can drive the anti-slip pad 24 to move closer to the ground. The anti-slip pad 24 can fill the gap between the pad 23 and the ground. At the same time, the anti-slip pad 24 has good anti-slip performance. Therefore, the entire fixing mechanism 1 can better adapt to uneven ground with the cooperation of the auxiliary mechanism 2. Even if the ground is slightly tilted, it can perform anti-slip and leveling treatment to avoid the center of gravity of the folding door shifting.
[0027] Working principle:
[0028] like Figures 1-3 As shown, in use, the folding door can be moved between the counterweight 11 and the clamping plate 17. Then, one of the worker's feet is placed inside the placement block 14, and the fixing mechanism 1 is fixed. At this time, the handle 101 is turned, which drives the threaded rod 15 to rotate. With the cooperation of the rotating plate 19, the threaded rod 15 can stably drive the threaded block 16, allowing the threaded block 16 to move. Thus, the clamping plate 17, which is fixedly connected to the threaded block 16, can drive the rubber pad 18 closer to the folding door. The process continues until the clamping plate 17 compresses and deforms the rubber pad 18, and the folding door remains stable. Then, the rotating block 25 is rotated, which drives the threaded column 22 to rotate. The threaded column 22 can rotate and move with the cooperation of the connecting block 21. As a result, the pad 23 and the anti-slip pad 24 can fit tightly against the ground under the action of the threaded column 22, improving the stability of the fixing mechanism 1. If the folding door shifts, the auxiliary mechanism 2 can be used to level the center of gravity of the folding door, making the folding door more stable during maintenance.
[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
