Specific implementation manner
[0022] The following are specific embodiments of the present invention and in combination with the attached drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0023] As Figure 1 、 2 shown in 3, 4, 5, 6, 7, this rolling door includes a positioning rod 1, a reel 2, a bottom rod 3 and a hook-shaped hanging ear 4. The first fixing plate 5 and the second fixing plate 6 are respectively arranged on both sides of the positioning rod 1 and the reel 2. The adjusting unit 7 is arranged on the first fixing plate 5, and the locking unit 8 is arranged on the second fixing plate 6. The adjusting unit 7 includes an adjusting wheel 701 rotatably arranged on the first fixing plate 5. A plurality of first ratchet teeth 702 are fixedly connected to the surface of the adjusting wheel 701. The inner wall of the reel 2 is clamped with a drive plate 9. A threaded column 10 is fixedly connected to the side of the drive plate 9 opposite to the adjusting wheel 701. A torsion spring 11 is fixedly arranged on the threaded column 10. An open tube 12 integrated with the reel 2 is arranged on the reel 2. A card slot 13 clamped on the open tube 12 is opened on the drive plate 9. The reel 2 and the bottom rod 3 are used to connect the curtain sheets. When pulling the rolling door to close, the torsion spring 11 will store energy. When the rolling door is opened, the torsion spring 11 will release energy to help the rolling door rise quickly. When the torsion spring 11 becomes loose after long-term use, the rising speed of the rolling door will be slower. The user can change the state of the torsion spring 11 by rotating the adjusting wheel 701 on the fixing plate, so that the torsion spring 11 can store enough energy when the rolling door is closed, ensuring that the rolling door can reach the effect of rising quickly when it is opened.
[0024] Preferably, a first outer shell 14 is provided on the first fixing plate 5. A first positioning sleeve block 15 for positioning the positioning rod 1 is arranged inside the first outer shell 14. A first guiding groove 16 is arranged inside the first outer shell 14, and the first guiding groove 16 is used for guiding and limiting the sliding of the first movable block 703. An adjusting groove 17 for clamping the adjusting wheel 701 is formed on the first outer shell 14.
[0025] Preferably, a first movable block 703 is slidably arranged in the first guiding groove 16. A first spring 704 is fixedly connected between the first movable block 703 and the first positioning sleeve block 15. A first pawl 705 meshing with the first ratchet teeth 702 is fixedly connected to the bottom of the first movable block 703. An first movable groove 18 for controlling the first movable block 703 is formed on the first outer shell 14. When the rolling door is closed, the rolling shaft 2 is driven to rotate, and the rotation of the rolling shaft drives the transmission plate 9 to rotate, so that one end of the torsion spring 11 connected to the transmission plate 9 rotates. Through the engagement of the first ratchet teeth 702 on the adjusting wheel 701 and the first pawl 705, the adjusting wheel 701 is limited, so that neither the adjusting wheel 701 nor one end of the torsion spring 11 connected to the adjusting wheel 701 rotates. At this time, when the rolling door is closed, the torsion spring 11 will be deformed, and the torsion spring 11 will store energy.
[0026] Preferably, the locking unit 8 includes a locking wheel 801 rotatably arranged on the second fixing plate 6. A plurality of second ratchet teeth 802 are fixedly connected to the surface of the locking wheel 801. A clamping plate 26 integrated with the locking wheel 801 is arranged inside the locking wheel 801, and the clamping plate 26 is clamped at one end of the rolling shaft 2. The locking unit 8 can lock the state of the rolling door, and the rolling door can be in a variety of half-open door states. Through the clamping connection between the clamping plate 26 and the rolling shaft 2, the locking wheel 801 and the rolling shaft 2 can move in the same state.
[0027] Preferably, a second outer shell 19 is provided on the second fixing plate 6. A second positioning sleeve block 20 for positioning the positioning rod 1 is arranged inside the second outer shell 19. A second guiding groove 21 is arranged inside the second outer shell 19, and the second guiding groove 21 is used for guiding and limiting the sliding of the push pressing plate 803 and the second movable block 804. A rotating groove 22 for clamping the locking wheel 801 is arranged inside the second outer shell 19.
[0028] Preferably, a push plate 803 and a second movable block 804 are slidably connected in the second guide groove 21, and the push plate 803 and the second movable block 804 are engaged with each other. A push button 805 is fixedly connected to one side of the push plate 803. An activity groove 806 for controlling the push button 805 is formed in the second housing 19. A second spring 807 is fixedly connected between the second movable block 804 and the second positioning sleeve block 20. A second pawl 808 engaged with the second ratchet tooth 802 is fixedly connected to the bottom of the second movable block 804. When the rolling door needs to be opened, the push button 805 is pushed to move the push plate 803, and the push plate 803 pushes the second movable block 804 to move, so that the second pawl 808 disengages from the second ratchet tooth 802. At this time, the locking wheel 801 and the reel 2 rotate synchronously to open the rolling door. When the second pawl 808 is engaged with the second ratchet tooth 802, the locking wheel 801 and the reel 2 can be locked from rotating any further, thereby locking the state of the rolling door.
[0029] Preferably, mounting seats 23 are arranged at the tops of the first housing 14 and the second housing 19. Limit rings 24 are fixedly arranged at both ends of the bottom rod 3. The number of the hook-shaped hanging ears 4 is two. Mounting holes 25 are arranged on the hook-shaped hanging ears 4. The hook-shaped hanging ears 4 are mounted below the low rod. When the rolling door is closed, the limit rings 24 on the bottom rod 3 are snapped onto the hook-shaped hanging ears 4, thereby maintaining the stability of the closed state of the rolling door.
[0030] Preferably, a rotating plate 27 is arranged between the reel 2 and the adjusting wheel 701. A convex block 28 integrated with the rotating plate 27 is arranged on one side of the rotating plate 27, and the convex block 28 is snapped into the opening tube 12. A limit rod 29 is fixedly connected to the inner wall of the transmission plate 9, and one end of the limit rod 29 is rotatably arranged in a threaded post 10 on the adjusting wheel 701. Arranging the rotating plate 27 can reduce the influence on the adjusting wheel 701 when the reel 2 rotates, and the rotating plate 27 can limit the threaded post 10 on the adjusting wheel 701. The limit rod 29 functions to limit the torsion spring 11.
[0031] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
