Description

Technical Field

[0001] This utility model relates to the field of roller shutter door technology, specifically a roller shutter door locking strip. Background Technology

[0002] Roller shutters are doors with multiple articulated door panels linked together, moving up and down within fixed tracks, rotating around a central axis at the top. Roller shutters are commonly used in shops.

[0003] Chinese Utility Model Publication No. CN222391306U discloses a roller shutter door locking strip, relating to the field of roller shutter door technology. The roller shutter door locking strip includes a roller shutter door panel, a roller shutter door strip, and a mounting plate. The front of the panel has multiple placement racks arranged side-by-side, each rack having movably fitted with ball bearings. The front of the roller shutter door panel has a slot, inside which multiple limiting grooves are arranged side-by-side. A snap-fit ​​component is fixedly connected to the rear end of the roller shutter door panel, with clamping grooves at the bottom and near the front end of the bottom of the snap-fit ​​component. A door strip positioning component is fixedly installed on the front of the roller shutter door strip. Multiple second springs are arranged side-by-side near the top and bottom of the rear end of the mounting plate. Bases are fixedly installed on the left and right sides of the rear end of the mounting plate near the center. A connecting rod is provided at one adjacent end of each of the two bases, and a first clamping semi-circular ring and a second clamping semi-circular ring are cross-arranged on the connecting rod.

[0004] This device reduces frictional resistance and improves the installation efficiency between the second snap-fit ​​component at the rear end of the roller shutter strip and the slot. However, the sliding plate of this device is sleeved on the sliding rod. After the first spring has been used for a period of time and the elasticity has weakened, the sliding plate is not easy to disassemble and replace the first spring. Therefore, its practicality is not very good and there is still room for improvement. Utility Model Content

[0023] 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.

[0024] In the prior art, the roller shutter door panel 1, roller shutter door strip 2 and mounting plate 3 are included. A door strip positioning member 4 is fixedly installed on the front of the roller shutter door strip 2. A second slot 14 is provided on one side of the roller shutter door panel 1 and a snap-fit ​​member 15 is provided on the other side of the roller shutter door panel 1. The snap-fit ​​member 15 and the second slot 14 are snap-fitted together.

[0025] Please see Figure 1-4 This utility model discloses a locking strip for a roller shutter door. The upper part of the roller shutter door panel 1 has an installation groove, in which a fixing plate 5 is installed. Several telescopic components are fixedly installed on one side of the fixing plate 5. Installing the fixing plate 5 in the installation groove facilitates the disassembly and installation of the telescopic components. One side of the telescopic component has a rolling groove, in which a ball 6 is rolled. The side wall of the roller shutter door panel 1 has a guide groove 7, one end of which intersects with the installation groove. The ball 6 passes through the guide groove 7, pushing the rear end of the roller shutter door panel 2's second locking member 15 into the locking groove, thus avoiding interference with the connection between the rear end locking member 15 and the locking groove. The upper part of the installation groove has a threaded hole, and a bolt is threadedly installed. A cover is installed through the upper part of the bolt. The cover is installed in the upper part of the installation groove through the threaded connection of the bolt and the threaded hole, protecting the fixing plate 5 and the telescopic components.

[0026] The mounting slot includes a slot 8, and a slot 9 is provided on one side of the slot 8. A card plate 10 is installed in the slot 9. The card plate 10 and the fixing plate 5 are fixed together. The fixing plate 5 can be fixed in the slot 8 by the card plate 10 and the slot 9.

[0027] The telescopic assembly includes an outer tube 11, an inner rod 12 is slidably installed inside the outer tube 11, a roller groove is provided at one end of the inner rod 12, a spring 13 is fixedly installed inside the outer tube 11, and the other end of the spring 13 is fixedly installed at the other end of the inner rod 12. The spring 13 generates a thrust on the inner rod 12, and the thrust is transmitted to the ball 6, so that the ball 6 supports the snap-fit ​​part 15.

[0028] One end of the guide groove 7 intersects with the second slot 14, which facilitates the ball 6 to pass through the guide groove 7 and support the snap-fit ​​part 15.

[0029] In summary, when using this roller shutter door locking strip, align the locking plate 10 with the slot 9, and securely install the fixing plate 5 in the groove 8 using a snap-fit ​​method. Install the telescopic assembly on one side of the fixing plate 5, ensuring that one end of the spring 13 is fixed inside the outer tube 11 and the other end is connected to the inner rod 12. The end of the inner rod 12 with the rolling groove faces the guide groove 7 on the side wall of the roller shutter door panel 1. Place the ball 6 in the rolling groove of the inner rod 12 of the telescopic assembly, allowing the ball 6 to roll freely within the rolling groove. At this point, the telescopic assembly and other devices are installed. After a period of use, when the elasticity of the spring 13 in the telescopic device weakens, simply lift the fixing plate 5 upwards to disengage the locking plate 10 from the slot 9. After replacing it with a new one, the fixing plate 5 and the telescopic device can be taken to the maintenance location for repositioning.

[0030] 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.
