[0020] 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.

[0021] Reference Figures 1 to 4 The roller shutter door bottom beam lock device shown includes a winding mechanism 5, a drive mechanism 1 for driving the winding mechanism 5 to wind up, a roller shutter door 4 mounted on the winding mechanism 5, a bottom beam 3 mounted at the bottom of the roller shutter door 4, and two guide plates 2 for limiting the swaying of the roller shutter door 4. The bottom beam 3 is hollow, and a door lock 6 is mounted in the middle of the bottom beam 3. A reinforcing member 7 is mounted above the inner cavity of the bottom beam 3. A linkage triggering mechanism 8 is mounted on both sides of the door lock 6, and the linkage triggering mechanism 8 is connected to the reinforcing member 7.

[0022] The guide plate 2 includes a U-shaped channel steel 21, a gravity triggering component disposed below the sliding cavity of the U-shaped channel steel 21, and a lateral outward displacement component connected to the gravity triggering component. When the bottom beam 3 contacts the gravity triggering component, the gravity triggering component causes the lateral outward displacement component to abut against the edge of the roller shutter door 4.

[0023] When using the bottom beam lock, the roller shutter door 4 is restricted by the U-shaped channel steel 21 during its up and down movement, ensuring the stable movement of the bottom beam 3. When the bottom beam 3 contacts the gravity trigger component, the gravity trigger component is subjected to pressure and moves downward. At this time, the gravity trigger component drives the lateral outward movement component to move to the position of the roller shutter door 4. The abutment block on the lateral outward movement component contacts the side of the roller shutter door 4, thereby allowing the roller shutter door to be subjected to opposing squeezing force in the length direction, keeping it stable. This can overcome the problem of excessive shaking and abnormal noise of the roller shutter door after a collision.

[0024] In the specific implementation of the above scheme, the gravity triggering component includes a receiving plate 28, a slider 27 is provided at one end of the receiving plate 28, the slider 27 is elastically connected to the sliding cavity through a compression spring, a triggering vertical bar 22 is fixedly connected to one side of the slider 27, and a guide block 23 is provided on one side of the triggering vertical bar 22.

[0025] The lateral outward movement component includes a slide plate 24, a guide block 25 is provided on one side of the slide plate 24, a guide block 23 contacts the guide block 25, and an engagement block 26 is fixedly connected to the outer side of the slide plate 24. The engagement block 26 has slots on both the upper and lower sides and passes through the U-shaped channel steel 21.

[0026] In this specific implementation, the receiving plate 28 is subjected to pressure from the bottom beam 3. The receiving plate 28 drives the slider 27 to move downward. In this way, the slider 27 compresses the compression spring. When the vertical bar 22 is triggered to move downward, the guide block 1 23 pushes the guide block 25 outward. In this way, the slide plate 24 where the guide block 25 is located moves outward. The abutment block on the slide plate 24 contacts the side of the roller shutter door 4, thereby stabilizing the roller shutter door in the length direction.

[0027] A reinforcing plate 31 is provided on the outer side of the bottom beam 3, and multiple lifting ports are opened at equal intervals on the reinforcing plate 31.

[0028] To improve the strength of the bottom beam 3, the reinforcing plate 31 can shield the ground rod 81. The reinforcing plate 31 is made of steel, which can improve the impact resistance of the bottom beam 3 and improve its stability.

[0029] The reinforcement component 7 includes multiple pull ropes 71 and connecting plates 73 connected to the roller shutter door 4. The pull ropes 71 pass through the top of the bottom beam 3. Multiple gears 72 are provided on the connecting plate 73. A reel for winding around the pull ropes 71 is provided on one side of the gears 72. It also includes a rack 74 fixedly connected to the inner wall of the bottom beam 3. The gears 72 mesh with the rack 74.

[0030] The linkage triggering mechanism 8 includes a lock plate 82, which is sleeved on the door lock 6, and the lock cylinder drives the turntable to rotate.

[0031] The linkage triggering mechanism 8 also includes a guide wheel and a connecting rope 83. The turntable is fixed to the connecting rope 83. Multiple hinge rods 84 are provided on the locking plate 82. The hinge point of the connecting rope 83 and the hinge rod 84 is fixed. The hinge rod 84 is hinged to the connecting plate 73. One end of the connecting rope 83 is fixedly connected to a sliding plate 85.

[0032] It also includes a grounding rod 81, which is fixedly connected to the bottom of the connecting plate 73 and passes through the lifting port on the bottom beam 3.

[0033] The linkage triggering mechanism 8 also includes an elastic sleeve 89, which has two locking rods 87 connected elastically inside. The locking rods 87 pass through the sliding opening 88 on the inner wall of the bottom beam 3 and are engaged in the opening. The slide plate 85 is connected to the end of the locking rod 87 through the pull rope 86.

[0034] When the door lock 6 locks the roller shutter door 4, the turntable rotates when the door lock 6 rotates. The turntable drives the connecting rope 83 to slide on the guide wheel. As the connecting rope 83 pulls the hinge rod 84 to bend, the hinge rod 84 can drive the connecting plate 73 to move downward. At this time, the multiple pull ropes 71 on the connecting plate 73 can remain taut after the roller shutter door 4 descends. In this way, the pull ropes 71 can improve the restraint on the swaying of the roller shutter door and improve stability.

[0035] Specifically, when the pull rope 71 is wound around the reel and the gear 72 meshes with the rack 74, the reel tightens the pull rope 71. At this time, the pull rope 71 can remain taut after the roller shutter door 4 descends. At this time, the grounding rod 81 on the connecting plate 73 descends from the lifting port to the insertion hole on the ground, which can lock in multiple directions and improve the stability of the roller shutter door.

[0036] It should be understood that when the slide plate 85 is pulled and slid, the two locking rods 87 move in opposite directions within the elastic sleeve 89, so that the locking rods 87 are locked onto the engagement block 26, thus completing the locking.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
