Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] refer to Figures 1 to 4 An anti-detachment tail end mechanism for a roller shutter includes a tail end assembly 1 and a bracket assembly 2; The tail end assembly 1 includes a tail end body 11 and a column 12; the tail end body 11 is connected to the shaft of the roller shutter, for example, inserted into the end of the shaft, and the column 12 is located on one side of the tail end body 11. The column 12 is inserted into the tail end body 11, or it can be rotatably connected to the tail end body 11 through a bearing.

[0020] The bracket assembly 2 includes a base 22, an anti-slip component 23, and a side frame 21; The seat 22 is a shell structure. The seat 22 has an inclined groove 221. The beginning end 221a of the groove 221 is open. The end end 221b of the groove 221 is located in the middle of the seat 22. The beginning end 221a is located diagonally above the end end 221b, thus forming an inclined groove 221, which facilitates the smooth entry of the column 12 into the groove 221 without any obstruction. The groove wall 223 of the groove 221 has a first opening 224.

[0021] refer to Figure 3 The seat 22 is located on one side of the side frame 21; the side frame 21 is L-shaped, and the seat 22 can be connected to the side frame 21 by screws or the like.

[0022] refer to Figure 4 The anti-slip component 23 is located inside the seat body 22. The anti-slip component 23 includes a hook 231, which includes a hook head 2310. The hook head 2310 corresponds to the first opening 224 and has an extended state and a retracted state. When the column 12 enters the end 221b of the groove 221, the hook 2310 extends outward, thereby preventing the column 12 from detaching from the groove 221 and improving the stability of the connection assembly.

[0023] refer to Figure 5 and Figure 6 The hook 231 rotates to cause the hook head 2310 to switch between an extended state and a retracted state.

[0024] refer to Figure 4 The anti-detachment component 23 also includes an elastic part 232, which drives the hook head 2310 to change from a retracted state to an extended state.

[0025] refer to Figure 4 The anti-detachment component 23 also includes a switch 234, which drives the hook 2310 to change from an extended state to a retracted state. For example, the state change is achieved by applying an external force to the switch 234 to cause the hook 2310 to rotate.

[0026] refer to Figure 4The anti-detachment component 23 also includes a rotating shaft portion 233, which has a shaft hole 2331. The base body 22 has a convex shaft 227 that mates with the shaft hole 2331. The rotating shaft portion 233 is located approximately in the middle of the anti-detachment component 23, thereby enabling the anti-detachment component 23 to rotate. The rotation allows the hook head 2310 to change between its extension and retraction states.

[0027] refer to Figure 4 The end of the hook 231 away from the hook head 2310 is connected to the rotating shaft 233; The elastic part 232 is rod-shaped or strip-shaped. One end of the elastic part 232 is connected to the limiting fulcrum 228 of the seat 22, for example, by abutting, and the other end of the elastic part 232 is connected to the rotating shaft part 233. The limiting fulcrum 228 can be a protruding plate-shaped, column-shaped or other structure. When the anti-detachment part 23 rotates, the limiting fulcrum 228 causes the elastic part 232 to deform. One end of the switch part 234 is connected to the rotating shaft part 233, and the other end of the switch part 234 extends out of the seat body 22. Thus, the entire anti-detachment component 23 is roughly Y-shaped.

[0028] refer to Figure 4 The side wall 225 of the seat 22 is provided with a second opening 226 corresponding to the switch part 234. The switch part 234 extends out of the seat 22 through the second opening 226.

[0029] refer to Figure 4 The outer side 2311 of the end 221b of the hook 2310 away from the groove 221 is inclined. In this way, when the column 12 pushes the outer side 2311, the outer side 2311 can generate a component force, thereby pushing the hook 2310 to retract, which is convenient for assembly.

[0030] The anti-slip component 23 is made of elastic plastic, such as PE, PU, ​​PP, nylon, etc. The thickness of the elastic part 232 is smaller than that of the hook part 231 and the switch part 234, which helps to increase the elasticity of the elastic part 232. The thickness of the hook part 231 and the switch part 234 is relatively larger, which helps to increase the strength and rigidity of the hook part 231 and the switch part 234.

[0031] refer to Figures 4 to 6 During assembly, the tail end of the column 12 enters from the beginning end 221a of the groove 221 and then touches the outer surface 2311 of the hook head 2310. Under the pushing action, the inclined outer surface 2311 forms a component force, thereby driving the hook head 2310 to retract. At this time, the anti-detachment component 23 rotates and the elastic part 232 deforms. When the column 12 passes the hook head 2310 and enters the end end 221b of the groove 221, the elastic part 232 drives the hook part 231 to rotate in the opposite direction and reset under the action of elastic force. Then the hook head 2310 extends and resets. In this way, the hook head 2310 realizes the limitation of the column 12 and prevents the column 12 from detaching.

[0032] During disassembly, an external force F is applied to the switch part 234, causing the switch part 234 to rotate and drive the hook part 231 to rotate. The hook head 2310 retracts, and the elastic part 232 deforms. When the column 12 moves out of the groove 221, the external force F is removed. Under the action of the elastic force, the elastic part 232 drives the hook part 231 to rotate in the opposite direction and reset, and then the hook head 2310 extends and resets.

[0033] The inclination angle of the trough 221 is about 45 degrees, which makes it easy for the tail end component 1 to be assembled onto the bracket component 2 and is not easily obstructed by the side frame 21.

[0034] refer to Figure 7 The column head 120 of the column body 12 is T-shaped, and the cross-section of the groove 221 is an inverted T-shaped, thereby achieving axial positioning of the column body 12.

[0035] The above description only discloses some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
