Description

Technical Field

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

[0002] Roller shutters, also known as rolling doors, are doors made up of multiple articulated door panels linked together. They rotate up and down within fixed tracks around a central axis at the top of the door and are commonly used in warehouses, shops, and other similar locations.

[0003] For non-electric roller shutters, manual operation is required when opening or closing. When closing, the operator pulls the door panel down forcefully; if the panel descends too quickly, it may hit the ground, potentially damaging both the floor and the door panel. Conversely, when opening, the operator pushes the door upwards forcefully, causing it to move rapidly; if this movement is too fast, the door panel may also collide with the top of the door frame. To address this, we propose a roller shutter buffer device. Utility Model Content

[0004] This utility model provides a roller shutter door buffer device, which has the advantage of allowing the limiting post to move up and down in the limiting groove and be subject to a certain resistance, so that the door panel will have a buffering effect when it is raised to the highest point or about to the lowest point, thus solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A roller shutter door buffer device is designed, including a strip seat. A plurality of spaced limiting grooves are provided on one side surface of the strip seat. A first support is provided on one side edge of the mounting plate. A limiting post is movably provided in the first support. One end of the limiting post extends outside the mounting plate, and the other end of the limiting post is placed on the side of the mounting plate and connected to an elastic mechanism. Under the drive of the elastic mechanism, the end of the limiting post always extends outside the mounting plate. The strip seat is installed on the guide groove, and the mounting plate is installed on the edge of the door panel near the strip seat, so that the limiting post rises and falls with the door panel and the limiting post is in elastic contact with the limiting groove.

[0006] Preferably, the end of the strip seat near the limiting groove is provided with a guide slope.

[0007] Preferably, the strip seats are all mounted on the strip plate, and the strip plate is detachably connected to the guide groove.

[0008] Preferably, the elastic mechanism includes a second support movably sleeved on the limiting post, a return spring sleeved on the limiting post between the second support and the first support, one end of the return spring near the first support abutting against the limiting seat, the limiting seat and the limiting post being coaxially connected, and the two ends of the return spring being in elastic contact with the second support and the limiting seat, respectively.

[0009] Preferably, the first support and the second support are provided with a mounting seat on one side. The mounting seat is fixed on the side of the mounting plate. The mounting seat is provided with an adjustment groove parallel to the first support and the second support. The first support and the second support are respectively connected to the adjustment groove by fasteners.

[0010] Preferably, the mounting plate is detachably provided with a sealing shell, and one end of the sealing shell is provided with a slot for placing the limiting post.

[0011] Preferably, the end of the limiting post furthest from the mounting plate is spherical.

[0012] Preferably, the limiting groove is a semi-circular groove, and two adjacent limiting grooves are connected by a circular arc transition.

[0013] Compared with the prior art, when the limiting post moves up and down, the limiting post contacts the strip seat. The end of the limiting post is squeezed and retracted by the guide slope. The end of the limiting post enters the limiting groove and makes elastic contact with the limiting groove. The limiting groove will block the limiting post. Therefore, the limiting post can move up and down in the limiting groove and is subject to a certain resistance, so that when the door panel is raised to the highest point or about to the lowest point, there will be a buffering effect.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Reference Figures 1 to 4 This utility model provides a technical solution: a roller shutter door buffer device, including a strip seat 2, a plurality of spaced limiting grooves 5 on one side surface of the strip seat 2, the limiting grooves 5 are semi-circular grooves, and two adjacent limiting grooves 5 are connected by an arc transition, and a guide slope 9 is provided at one end of the strip seat 2 near the limiting grooves 5.

[0022] like Figure 2 and Figure 3 As shown, the strip seats 2 are all installed on the strip plates 3. The strip plates 3 and the guide grooves 1 are detachably connected. Specifically, the strip plates 3 and the guide grooves 1 are fixed by bolts or rivets.

[0023] Corresponding to the strip seat 2, this application also includes a mounting plate 7. A first support 12 is provided on one side edge of the mounting plate 7. A limiting post 8 is movably provided in the first support 12. One end of the limiting post 8 extends outside the mounting plate 7, and the end of the limiting post 8 away from the mounting plate 7 is spherical or arc-shaped.

[0024] The other end of the limiting post 8 is located on the side of the mounting plate 7 and connected to the elastic mechanism. The elastic mechanism includes a second support 15 movably sleeved on the limiting post 8. A return spring 14 is sleeved on the limiting post 8 between the second support 15 and the first support 12. The end of the return spring 14 near the first support 12 abuts against the limiting seat 13. The limiting seat 13 is coaxially connected to the limiting post 8. It should be noted that both ends of the return spring 14 are in elastic contact with the second support 15 and the limiting seat 13, respectively. Figure 3 As shown, under the action of the elastic mechanism, the end of the limiting post 8 always extends outside the mounting plate 7. When the limiting post 8 is squeezed, the limiting post 8 will retract towards the mounting plate 7. However, after the external force squeezing the limiting post 8 is removed, the limiting post 8 returns to its initial state under the action of the return spring 14.

[0025] It should be noted that when the roller shutter door is rising, the main precautions are to prevent it from rising too quickly, causing the door to collide with the top of the door frame, and when it is falling, to prevent it from falling too quickly, causing the bottom of the door to hit the ground. The specific installation configuration is as follows: Figure 1As shown, the strip seat 2 is installed on the guide groove 1, and the strip seat 2 can be distributed at the upper and lower ends of the guide groove 1. The mounting plate 7 is installed on the edge of the door panel 4 near the strip seat 2, so that the limiting post 8 rises and falls with the door panel 4. The door panel 4 is located on one side of the strip seat 2 and at the bottom of the door panel 4. When the limiting post 8 rises and falls, the limiting post 8 contacts the strip seat 2, and the end of the limiting post 8 is squeezed and retracted by the guide slope 9. The end of the limiting post 8 enters the limiting groove 5 and makes elastic contact with the limiting groove 5. When the limiting post 8 moves in the limiting groove 5, the limiting groove 5 will have a blocking effect on the limiting post 8, but the limiting post 8 can retract. Therefore, the limiting post 8 can move up and down in the limiting groove 5 and is subject to a certain resistance.

[0026] This creates a phenomenon where, when the door panel 4 is lifted upwards or pulled downwards, a "click-click-click" sound is emitted when the limiting post 8 contacts the limiting groove 5. This helps the door panel 4 to slow down and buffer, preventing the door panel 4 from colliding with the ground or the top of the door frame. Moreover, the clicking sound can also remind the operator that the height of the door panel 4 is about to reach the desired position.

[0027] Moreover, the limiting groove 5 and the limiting post 8 can also play a positioning role. When the door panel 4 is raised to the top, the end of the limiting post 8 will abut against the limiting groove 5. After the external force is removed, the door panel 4 is limited by the limiting groove 5. When the door panel 4 is pulled, the limiting post 8 can be dislodged from the limiting groove 5.

[0028] When door panel 4 is at the bottom of the door frame, the operator can press down on door panel 4 to make the bottom of door panel 4 contact the ground, thus closing the door.

[0029] Furthermore, to ensure accurate alignment of the limiting post 8 with the limiting groove 5 during installation, such as... Figure 3 As shown, a mounting base 11 is provided on one side of the first support 12 and the second support 15. The mounting base 11 is fixed to the side of the mounting plate 7. An adjustment groove 16 parallel to the first support 12 and the second support 15 is opened on the mounting base 11. The first support 12 and the second support 15 are respectively connected to the adjustment groove 16 by fasteners, which are bolts. In this way, the height of the first support 12 and the second support 15 can be adjusted along the mounting base 11 so that the position of the limiting post 8 is aligned with the position of the limiting groove 5.

[0030] like Figure 1 and Figure 3 As shown, a sealing shell 6 is detachably provided on the mounting plate 7. One end of the sealing shell 6 is provided with a slot 10 for placing the limiting post 8. The limiting post 8 can be placed in the slot 10. The sealing shell 6 and the mounting plate 7 are specifically installed by bolts.

[0031] Based on the above embodiments, it should be further explained that, as Figure 1As shown, one strip seat 2 can correspond to multiple limiting posts 8. That is to say, multiple limiting posts 8 can be set on one side of the strip seat 2 so that multiple limiting posts 8 can contact the limiting groove 5. This will have a better limiting effect. The position of the limiting post 8 should correspond to the guide slope 9, and the end of the limiting post should not exceed the outside of the guide slope 9.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
