[0001] This utility model relates to the field of fireproof roller shutter technology, specifically to an anti-slip structure for fireproof roller shutters. Background Technology

[0002] The anti-slip structure of a fireproof roller shutter is a structure or mechanism designed to prevent the fireproof roller shutter from slipping during the opening and closing process. This design aims to improve the reliability and smooth operation of the fireproof roller shutter, ensuring that it can work stably under various working conditions, thereby avoiding problems such as jamming or unstable operation caused by slipping.

[0003] Chinese Utility Model Patent Publication No. CN 219119131 U discloses an anti-slip structure for a fireproof roller shutter. This anti-slip structure comprises a main body, an anti-slip plate, a screw, and nuts. The anti-slip plate, connected to the main body, is installed into the fireproof roller shutter through a groove. After the anti-slip plate is fitted together, the screw passes through it, and nuts are tightened at both ends of the screw to connect the anti-slip structure to the fireproof roller shutter. For replacement or maintenance, the anti-slip structure can be quickly removed by reversing the above steps. However, this anti-slip structure uses two hooks to connect the curtain panels, which are prone to deformation, resulting in poor stability during rolling. Furthermore, the anti-slip structure lacks reinforcement, leading to low robustness and poor practicality. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an anti-slip structure for fireproof roller shutters. It can effectively solve the problems of existing technology that uses two hooks to connect the curtain panels, the hooks are prone to deformation, the stability is poor when rolling up, there is no reinforcement structure, the firmness is low, and the practicality is poor.

[0005] The technical solution adopted by this utility model is: an anti-slip structure for a fireproof roller shutter, including a curtain panel one, a curtain panel two provided on the outer side of the curtain panel one, a connector one and a connector two fixedly installed on the outer side of the curtain panel one, a guide groove opened on the outer side of the connector two, a positioning groove opened on the top of the curtain panel one, a threaded hole one opened inside the positioning groove, a limit groove opened on the outer side of the connector one, a connector three provided between the curtain panel one and the curtain panel two, a locking groove opened on the outer side of the connector three, a threaded hole two opened on the top of the connector three, a bolt opened on the top of the connector three, a limit rod fixedly installed on the outer side of the connector three, a groove opened on the outer side of the curtain panel one, a reinforcing plate fixedly installed inside the groove, and a filler material provided inside the groove.

[0006] Preferably, the first curtain panel and the second curtain panel have the same structure, the first curtain panel and the second curtain panel are plugged in, and the first curtain panel and the second curtain panel are rotatably connected, with the rotation angle being 0° to 90°.

[0007] With the above technical solution, the workers can quickly install curtain panel one and curtain panel two by inserting connector one into the guide groove. The design of connector one and connector two facilitates the installation and disassembly of curtain panel one and curtain panel two, making it convenient for subsequent replacement. At the same time, the cooperation between connector one and connector two also makes it easy to roll up curtain panel one and curtain panel two, with high stability.

[0008] Preferably, the third connector is plugged into the first curtain panel, and the cross-section of the part of the third connector in contact with the first curtain panel has a "U" shaped structure.

[0009] Using the above technical solution, the staff can insert the third connector into the positioning groove, which enables the third connector to be quickly aligned. The positioning groove design facilitates the quick alignment of the third connector and makes subsequent fixing easier.

[0010] Preferably, the bolt extends through the second threaded hole into the interior of the first threaded hole, and the second threaded hole has the same diameter as the first threaded hole.

[0011] With the above technical solution, after quickly aligning the connector three, the workers can then insert the bolt through the threaded hole two and extend it into the threaded hole one, which can achieve the rapid installation of the connector three. The design of the bolt, threaded hole two, and threaded hole one facilitates the installation and disassembly of the connector three, and makes subsequent maintenance and repair convenient.

[0012] Preferably, the limiting rod is adapted to the limiting groove, and the rotation centers of the first and second curtain panels are on the same horizontal line as the rotation center of the third connecting member.

[0013] With the above technical solution, after the third connector is installed, the limiting rod is inserted into the limiting groove to limit the first connector. Through the design of the limiting rod and the limiting groove, when the first and second curtain panels are rolled up, the first and second curtain panels can be prevented from moving around and affecting the normal rolling of the whole, thus achieving high stability.

[0014] Preferably, there are two identical reinforcing plates, and the cross-section of the two reinforcing plates combined is a "∧" shaped structure.

[0015] The above technical solution, through the design of the reinforcing plate, makes the curtain panel more robust. The design of two reinforcing plates divides the groove into multiple triangles. Since triangles have stability, the overall robustness is further improved.

[0016] Preferably, the filler is located on the outside of the reinforcing plate, and the filler is made of rock wool.

[0017] Through the above technical solutions, rock wool has thermal insulation, fireproof, sound absorption and noise reduction, corrosion and moisture resistance, and safety and environmental protection properties, thus providing protection for the curtain panel.

[0018] Compared with the prior art, this utility model provides an anti-slip structure for fireproof roller shutters, which has the following beneficial effects:

[0019] 1. The fireproof roller shutter's anti-slip structure, through the design of connector one and connector two, facilitates the installation and disassembly of curtain panel one and curtain panel two, making subsequent replacement convenient. At the same time, through the cooperation of connector one and connector two, it is also easy to roll up curtain panel one and curtain panel two, resulting in high stability.

[0020] 2. The fireproof roller shutter's anti-slip structure uses two reinforcing plates to divide the groove into multiple triangles. Because triangles are stable, the overall robustness is further improved. Through the design of the limiting rod and limiting groove, when the first and second curtain panels are rolled up, the first and second curtain panels can be prevented from shifting, which would affect the normal rolling of the whole, resulting in high stability.

[0027] 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.

[0028] Example 1: As Figure 1-5 As shown, the present invention provides an anti-slip structure for a fireproof roller shutter, comprising a curtain panel 1, a curtain panel 2 on the outer side of the curtain panel 1, a connector 3 and a connector 4 fixedly installed on the outer side of the curtain panel 1, a guide groove 5 on the outer side of the connector 4, a positioning groove 6 on the top of the curtain panel 1, a threaded hole 7 inside the positioning groove 6, a limiting groove 8 on the outer side of the connector 3, a connector 3 9 between the curtain panel 1 and the curtain panel 2, a slot 10 on the outer side of the connector 3 9, a threaded hole 11 on the top of the connector 3 9, a bolt 12 on the top of the connector 3 9, a limiting rod 13 fixedly installed on the outer side of the connector 3 9, a groove 14 on the outer side of the curtain panel 1, a reinforcing plate 15 fixedly installed inside the groove 14, and a filler 16 inside the groove 14.

[0029] Specifically, curtain panel 1 and curtain panel 2 have the same structure. Curtain panel 1 and curtain panel 2 are installed by plugging in, and are also rotatably connected with a rotation angle of 0° to 90°. The advantages are that workers can quickly install curtain panel 1 and curtain panel 2 by inserting connector 1 3 into the guide groove 5. The design of connector 1 3 and connector 2 4 facilitates the installation and disassembly of curtain panel 1 and curtain panel 2, making subsequent replacement convenient. Furthermore, the cooperation between connector 1 3 and connector 2 4 also facilitates the winding of curtain panel 1 and curtain panel 2, resulting in high stability.

[0030] Specifically, connector 39 and curtain panel 1 are installed by plugging in, and the cross-section of the contact part between connector 39 and curtain panel 1 has a "U" shape. The advantage is that the operator can quickly align connector 39 by inserting it into the positioning groove 6. The design of the positioning groove 6 facilitates the quick alignment of connector 39 and makes subsequent fixing easier.

[0031] Specifically, bolt 12 extends through threaded hole 11 into threaded hole 7, and threaded hole 11 has the same diameter as threaded hole 7. The advantage is that after quickly aligning connector 9, the operator can then extend bolt 12 through threaded hole 11 into threaded hole 7, enabling rapid installation of connector 9. The design of bolt 12, threaded hole 11, and threaded hole 7 facilitates the installation and disassembly of connector 9, and makes subsequent maintenance and repair easier.

[0032] Example 2: Figure 2-5 As shown, this is an improvement on the previous embodiment.

[0033] Specifically, the limiting rod 13 is adapted to the limiting groove 8, and the rotation center of curtain panel 1 and curtain panel 2 is on the same horizontal line as the rotation center of connector 3 9. The advantage is that after connector 3 9 is installed, the limiting rod 13 is inserted into the limiting groove 8, which can limit connector 3. Through the design of the limiting rod 13 and the limiting groove 8, when curtain panel 1 and curtain panel 2 are rolled up, it can prevent curtain panel 1 and curtain panel 2 from shifting, thus avoiding affecting the normal rolling of the whole, resulting in high stability.

[0034] Specifically, there are two identical reinforcing plates 15, and the cross-section of the combined reinforcing plates 15 forms a "∧" shape. The advantage is that the design of the reinforcing plates 15 makes the curtain panel 1 more robust. By using two reinforcing plates 15, the groove 14 is divided into multiple triangles. Since triangles have stability, the overall robustness is further improved.

[0035] Specifically, the filler 16 is located on the outside of the reinforcing plate 15, and the filler 16 is made of rock wool. The advantages are that rock wool has thermal insulation, fire resistance, sound absorption and noise reduction, corrosion and moisture resistance, and is safe and environmentally friendly, thus protecting the curtain panel 1.

[0036] Working Principle: During installation, the operator inserts connector 3 into the guide groove 5, enabling quick installation of curtain panel 1 and curtain panel 2. The design of connectors 3 and 4 facilitates the installation and removal of curtain panels 1 and 2, making subsequent replacement convenient. The cooperation between connectors 3 and 4 also facilitates the winding of curtain panels 1 and 2, ensuring high stability. The operator then inserts connector 9 into the positioning groove 6, enabling quick alignment of connector 9. The positioning groove 6 facilitates quick alignment of connector 9, making subsequent fixing convenient. After quick alignment of connector 9, the operator inserts bolt 12 through threaded hole 11 into threaded hole 7, enabling quick installation of connector 9. The design of hole 11 and threaded hole 7 facilitates the installation and disassembly of connector 9, and makes subsequent maintenance and repair convenient. During use, after connector 9 is installed, the limiting rod 13 is inserted into the limiting groove 8 to limit connector 3. Through the design of the limiting rod 13 and the limiting groove 8, when curtain 1 and curtain 2 are rolled up, it can prevent curtain 1 and curtain 2 from moving around and affecting the normal rolling of the whole, thus achieving high stability. The design of the reinforcing plate 15 makes curtain 1 more robust. The design of the two reinforcing plates 15 divides the groove 14 into multiple triangles. Since triangles have stability, the overall robustness is further improved. Rock wool has thermal insulation, fireproof, sound absorption and noise reduction, corrosion and moisture resistance, and safety and environmental protection properties, which protect curtain 1.
