Description

Technical Field

[0001] The utility model relates to the technical field of rolling shutter doors, in particular to a silent connecting mechanism for rolling shutter door panels. Background Art

[0002] There are many reasons why rolling doors make loud noises, the most common ones are as follows:

[0003] 1. The track is uneven or slightly curved: When the rolling door slides, it rubs against the uneven track, making noise.

[0004] 2. Aging of springs or shock-absorbing rods: After a long period of use, the springs and shock-absorbing rods on the rolling shutter door may age and lose some of their shock-absorbing effect, causing the noise to become louder.

[0005] 3. Wear of rolling door panels: The rotating shafts between the rolling door panels may wear out after long-term use, increasing friction and generating noise.

[0006] 4. Friction between rolling door panels: Rolling door panels are often made of metal, mostly aluminum. When rolling door panels are bent up and down, they come into contact with each other and produce friction, making noises.

[0007] In order to reduce the noise problem of rolling shutter doors, the inventor has developed a silent connecting mechanism for rolling shutter door panels. Utility Model Content

The isolation ring pad 5 is made of rubber or other materials to prevent metal friction noise from being generated due to the friction between the two blade connectors 3 when the two blade connectors 3 rotate relative to each other. Every two longitudinally adjacent door curtain blades 1 are connected by a blade isolation strip 4. The blade isolation strip 4 connects the two door curtain blades 1 and also isolates the two adjacent door curtain blades 1 to prevent the two adjacent door curtain blades 1 from directly contacting each other and generating friction noise.

[0039] The roller 2 is supported by a shaft, and the shaft serves as a rotating shaft of the two blade connectors 3. The shaft runs through the connection between the two blade connectors 3. The blade connector 3 can rotate around the shaft, and the roller 2 is rotationally connected to the shaft.

[0040] A second limiting hole 21 is provided on the outer wall of the shaft rod, and a first limiting hole 33 is provided on the outer wall of one end of the blade connector 3. The first limiting hole 33 corresponds to the second limiting hole 21. Left and right pins are provided on the inner sides of the first limiting hole 33 and the second limiting hole 21. The pins pass through the first limiting hole 33 and the second limiting hole 21 at the same time, fixing the position of the shaft rod and a blade connector 3 to prevent the shaft rod from rotating itself and deviating to the left and right.

[0041] The inner wall of the blade connector 3 is configured as a horizontal plate groove 34, and the horizontal plate groove 34 corresponds to the inner wall size of the door curtain blade 1. The door curtain blade 1 and the blade connector 3 are reinforced by rivets. The door curtain blade 1 is embedded in the horizontal plate groove 34 and fixed, and the door curtain blade 1 and the blade connector 3 are reinforced by rivets.

[0042] A second shaft ring 32 is provided at one end of the blade connector 3, and a first shaft ring 31 is provided at the other end of the blade connector 3. When the two blade connectors 3 are connected, the first shaft ring 31 and the second shaft ring 32 are coaxial. The two adjacent blade connectors 3 are connected together by a shaft rod penetrating the axis of the first shaft ring 31 and the second shaft ring 32, and an isolation ring pad 5 is provided between the first shaft ring 31 and the second shaft ring 32 to isolate the first shaft ring 31 from the second shaft ring 32.

[0043] The blade isolation strip 4 is made of materials such as rubber and silicon. Rubber and silicon have a certain strength to connect two adjacent door curtain blades 1. At the same time, rubber and silicon make less noise when rubbing against the door curtain blades 1, which can play the role of connection and silencing.

[0044] Convex plates 11 are provided at the upper and lower ends of the outer side of the door curtain blade 1, and a groove 12 is formed on the inner side of the convex plate 11. The blade isolation strip 4 is embedded in the groove, so that the inner side of the door curtain blade 1 is relatively flat and beautiful, and a hook 13 is provided on the inner side of the groove 12; the upper and lower ends of the blade isolation strip 4 are provided with hooks 7, and the hooks 7 are connected with the hooks 13. The hooks 7 are inserted into the hooks 13 through the ends of the door curtain blades 1, and the hooks 7 are connected with the hooks 13 together, so that the blade isolation strip 4 connects two adjacent door curtain blades 1 to avoid gaps between the two door curtain blades 1, and at the same time, the two adjacent door curtain blades 1 are isolated to avoid collision and friction between the two adjacent door curtain blades 1.

[0045] A cavity 14 is provided inside the door curtain blade 1 , and the inside of the cavity 14 is filled with a heat insulating material, which may be glass wool or foam.

[0046] The bottom of the door curtain blade 1 is provided with a bottom pad 6, and the top of the bottom pad 6 is also provided with a hook 7. The hook 7 is connected with the hook 13 on the bottommost door curtain blade 1, thereby fixing the bottom pad 6. The bottom pad 6 uses a hollow rubber pad to play a buffering role, preventing the door curtain blade 1 from directly contacting the ground when the door curtain falls.

[0047] When the rolling door is relatively wide, multiple door curtain blades 1 can be used to extend horizontally, wherein every two horizontally adjacent door curtain blades 1 are connected by a blade connector 3, and the ends of the two door curtain blades 1 are respectively placed on the inner side of the horizontal plate groove 34 to fix the two door curtain blades 1.

[0048] The outer side of the door curtain blade 1 is provided with a printed surface.
