[0002] A roller shutter door is a door with multiple articulated door panels linked together, which rotate up and down around a central roller at the top of the door within a fixed track.

[0003] In existing roller doors, the curtain slides inside the track to form a seal during use. When it rains, rainwater enters the interior through the seam between the curtain and the track, causing insufficient waterproofing. Therefore, this utility model proposes a waterproofing device for roller doors. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof device for roller doors, so as to solve the problem mentioned in the background art that the roller doors are not waterproof enough when it rains because there is a certain gap at the connection between the door curtain and the track.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof device for a roller shutter, comprising a waterproof device body and a sealing box disposed at the connection between the door curtain and the track. The waterproof device body consists of a storage groove, symmetrically arranged limiting components, and a movable plate. The storage groove is opened on the surface of the track. The movable plate consists of plate A, plate B, and symmetrically arranged connecting components. Plate B is disposed on the side of plate A, and both plate A and plate B are disposed inside the storage groove. The symmetrically arranged connecting components are disposed at the connection between plate B and plate A. The symmetrically arranged limiting components are disposed at the connection between the bottom end of plate A and the storage groove.

[0006] Preferably, the width dimensions of plate A and plate B are the same as the width dimensions of the storage groove.

[0007] Preferably, the limiting component consists of a limiting groove and a limiting slider. The limiting groove is opened at the bottom end of the plate A, and the limiting slider is fixed to the inner side of the storage groove. The limiting slider and the limiting groove are in an engaged state, and the cross-section of the limiting slider has a T-shaped structure.

[0008] Preferably, the connecting assembly consists of a connecting block, a connecting groove, and a spring-loaded component. The connecting block is fixed to the side of plate B, the connecting groove is opened on the side of plate A, and the spring-loaded component is disposed at the connection between the connecting block and the connecting groove.

[0009] Preferably, the rebound assembly consists of a crossbar and a torsion spring. The crossbar passes through the inner side of the connecting block, and its two ends are respectively connected to the two sides of the connecting groove. The torsion spring is sleeved on the surface of the crossbar, and its two ends are respectively fixed to the inner side of the connecting block.

[0010] Preferably, an operation box is provided on the side of the track, and a motor is provided on the side of the sealing box.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By designing a waterproof device, the problem of water seepage at the joint between the curtain and the track in traditional roller doors is improved. This is because the gap between the curtain and the track allows rainwater to seep in during rainy weather, causing damage to the roller door over time. By installing a waterproof device at the joint between the curtain and the track, the joint is protected from rainwater infiltration while ensuring easy operation, thus ensuring the waterproof performance of the roller door during use.

Detailed Implementation

[0018] 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.

[0019] Please see Figures 1 to 4This utility model provides a technical solution: a waterproof device for a roller shutter, including a waterproof device body 4 and a sealing box 1 disposed at the connection between the door curtain 2 and the track 3. The waterproof device body 4 consists of a storage groove 41, symmetrically arranged limiting components 42, and a movable plate 43. The storage groove 41 is formed on the surface of the track 3 and is used to store the movable plate 43, so that when it is not necessary to seal the joint between the door curtain 2 and the track 3, the movable plate 43 can be stored in the limiting component 42. Inside panel 2, the movable plate 43 consists of plate A431, plate B432, and symmetrically arranged connecting components 433. Plate B432 is located on the side of plate A431, and both plate A431 and plate B432 are located inside the storage groove 41. The symmetrically arranged connecting components 433 are located at the connection between plate B432 and plate A431. The symmetrically arranged limiting components 42 are located at the connection between the bottom end of plate A431 and the storage groove 41. The designed waterproof device 4 improves upon the previous roller door design, which suffered from water seepage due to a gap at the joint between the curtain 2 and the track 3. This gap allowed rainwater to enter during rainy weather, causing damage to the roller door over time. By installing the waterproof device 4 at the joint between the curtain 2 and the track 3, the design protects this joint from rainwater intrusion while ensuring convenient operation, thus ensuring the roller door's waterproof performance during use. (Panel A431) The width dimension of the plate A432 is the same as the width dimension of the storage groove 41. The limiting component 42 consists of a limiting slide 421 and a limiting slider 422. The limiting slide 421 is opened at the bottom end of the plate A431. The limiting slider 422 is fixed to the inside of the storage groove 41. The limiting slider 422 and the limiting slide 421 are in an engaged state. The cross-section of the limiting slider 422 is T-shaped. An operation box is provided on the side of the track 3, and a motor is provided on the side of the sealing box 1.

[0020] In this embodiment, preferably, the connecting component 433 consists of a connecting block 4331, a connecting groove 4332, and a spring-loaded component 4333. The connecting block 4331 is fixed to the side of the plate B432, the connecting groove 4332 is formed on the side of the plate A431, and the spring-loaded component 4333 is disposed at the connection between the connecting block 4331 and the connecting groove 4332. When the plate B432 is separated from the plate A431, the connecting block 4331 is inside the connecting groove 4332, and the spring-loaded component 4333 is released by the torque of the torsion spring 4333B. Under the action, the plate B432 rotates around the through crossbar 4333A, sealing the end of the plate B432 with the joint between the curtain 2 and the track 3. The rebound assembly 4333 consists of the crossbar 4333A and the torsion spring 4333B. The crossbar 4333A passes through the inside of the connecting block 4331, and the two ends of the crossbar 4333A are respectively connected to the two sides of the connecting groove 4332. The torsion spring 4333B is sleeved on the surface of the crossbar 4333A, and the two ends of the torsion spring 4333B are respectively fixed to the inside of the connecting block 4331.

[0021] The working principle and usage process of this utility model are as follows: During the use of the roller shutter, after the curtain 2 is pulled down to complete the closure, the movable plate 43 stored inside the storage groove 41 is operated. By pushing the plates B432 and A431 to the side, the plates A431 and B432 move inside the storage groove 41 through the limiting slide groove 421 and the limiting slider 422. When the plate B432 is separated from the storage groove 41, under the torsion of the torsion spring 4333B, the plate B432 rotates around the through crossbar 4333A as the center, sealing the joint between the curtain 2 and the track 3. This ensures that the roller shutter is waterproof when it rains, by sealing the gap between the curtain 2 and the track 3.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
