Description

Technical Field

[0001] This utility model relates to the field of roller shutter door technology, specifically a novel structure for a roller shutter door counterweight plate. Background Technology

[0002] Roller shutters use a motor to drive the curtain slats to roll or unfold. The core function of the counterweight structure is to balance the weight of the curtain slats, reduce the motor load, and improve operational stability.

[0003] A search revealed a utility model patent with Chinese patent publication number CN211258425U, which discloses a PVC high-speed rolling shutter door, including a PVC rolling shutter door body. The PVC rolling shutter door body is rolled onto a rotating rod, and the right end of the rotating rod is rotatably connected to the output end of a servo motor. The rotating rod is installed on a door box, and a second metal gasket is fixed to the upper end of the door box. A first metal gasket is fixed to both the left and right ends of the door box. Both the first and second metal gaskets have through holes at equal intervals.

[0004] The aforementioned device achieves collision protection by setting a spring buffer at the bottom of the base. However, when encountering a slightly taller vehicle or cargo that is taller than the vehicle and hits the base, there is still a problem of damage. There is room for improvement. In addition, with the spring at the bottom, the base will be lifted up, creating a gap between it and the ground. Utility Model Content

[0005] The purpose of this utility model is to provide a novel structure for the counterweight plate of a roller shutter door to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel structure for a roller shutter door counterweight plate, comprising a counterweight plate body, a protective component installed at the bottom of the counterweight plate body, the protective component including two slots opened inside the counterweight plate body, both slots being located at the bottom of the counterweight plate body, a rod being slidably inserted inside the two slots, an air bladder being provided at the bottom of the rod, an arc-shaped groove adapted to the air bladder being provided on the outer wall of the bottom of the counterweight plate body, a through hole being opened on the outer wall of one end of the mounting ring, and a mounting ring being fixedly connected inside the through hole, an air injection head being threadedly connected inside the mounting ring, and a one-way valve being provided inside the air injection head.

[0007] This design effectively prevents injury to people or objects from impacts with the main body of the counterweight plate, and also avoids damage to vehicles or goods from scrapes caused by the counterweight plate. It adapts to uneven ground. When the second insert rod is inserted into the second slot, the airbag fixed at the bottom of the second insert rod forms a barrier below the main body of the counterweight plate. Because the airbag is soft, it will not cause injury to people or objects when the roller shutter door descends. When the door is open, if a tall vehicle or cargo hits the bottom of the main body of the counterweight plate, the airbag will prevent it from scratching the vehicle or cargo. When the door is closed, if it encounters uneven ground, the airbag will deform under pressure, thus better conforming to the ground and making the door close more securely and with better sealing.

[0008] As a further preferred embodiment of this technical solution, the main body of the counterweight plate has two slots three inside, and the two slots three are respectively located on both sides of slot two. Each of the two slots three has a rod three slidably inserted inside, and the two rods three are fixedly connected to the same protective cloth, which surrounds the outside of the airbag.

[0009] As a further preferred embodiment of this technical solution, a counterweight assembly is installed inside the counterweight plate body. The counterweight assembly includes several mounting slots opened in the middle of one side outer wall of the counterweight plate body. A single counterweight plate is slidably inserted into each of the several mounting slots, and two connecting pieces are provided on the outside of each of the several single counterweight plates.

[0010] The curtain fabric may expand and increase in weight by 5% to 10% in high-temperature environments. At this time, the bolts connecting the connecting piece and the counterweight plate body can be removed, and the counterweight plate can be taken out of the mounting groove, thereby reducing the overall mass of the counterweight plate body, reducing the load on the roller shutter door drive, reducing energy consumption, and improving practicality.

[0011] As a further preferred embodiment of this technical solution, the inner wall of the counterweight plate body near the counterweight plate piece is provided with several equally spaced support grooves, and one end of several counterweight plate pieces is slidably inserted into several support grooves.

[0012] As a further preferred embodiment of this technical solution, the airbag is equipped with a microwave radar sensor, and the sensor is equipped with a power supply module and a Bluetooth module. The power supply module is equipped with a lithium manganese dioxide button battery.

[0013] As a further preferred embodiment of this technical solution, a slot is provided inside the main body of the counterweight plate, and the slot is located at the top of the main body of the counterweight plate. A rod is slidably inserted into the slot, and a curtain is fixedly connected to the top of the rod.

[0014] As a further preferred embodiment of this technical solution, the main body of the counterweight plate is made of aluminum alloy.

[0015] This utility model provides a novel structure for a counterweight plate of a roller shutter door, which has the following beneficial effects:

[0016] (1) This utility model effectively prevents people or objects from being injured by impacts from the main body of the counterweight plate by setting protective components. It also prevents vehicles or goods from being damaged when scratched by the main body of the counterweight plate. It can adapt to uneven ground. When the second insert rod is inserted into the second slot, the airbag fixed at the bottom of the second insert rod will form a barrier under the main body of the counterweight plate. Because the airbag is soft, it will not cause injury to people or objects when the roller shutter door is descending. When the door is open, if a tall vehicle or cargo hits the bottom of the main body of the counterweight plate, the airbag can also prevent the main body of the counterweight plate from scratching the vehicle or cargo. When the door is closed, if it encounters an uneven ground, the airbag will deform due to compression, thereby better fitting the ground, making the door close more securely and with better sealing.

[0017] (2) By setting a counterweight component, the curtain may expand and increase in weight by 5% to 10% in a high-temperature environment. At this time, the bolts of the connecting piece and the main body of the counterweight plate can be removed, and the counterweight plate can be taken out from the mounting groove, thereby reducing the overall mass of the main body of the counterweight plate, reducing the load of the roller shutter door drive, reducing energy consumption, and improving practicality.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 2 and Figure 4As shown, in this embodiment, a novel structure for a roller shutter door counterweight plate includes a counterweight plate body 1. A protective component 5 is installed at the bottom of the counterweight plate body 1. The protective component 5 includes a second slot 501 opened inside the counterweight plate body 1, and the second slot 501 is located at the bottom of the counterweight plate body 1. A second rod 502 is slidably inserted into the second slot 501. An air bladder 503 is provided at the bottom of the second rod 502. An arc-shaped groove adapted to the air bladder 503 is provided on the outer wall of the bottom of the counterweight plate body 1. A through hole is opened on the outer wall of one end of the mounting ring 504, and the mounting ring 504 is fixedly connected inside the through hole. An air injection head 505 is threadedly connected inside the mounting ring 504, and a one-way valve is provided inside the air injection head 505.

[0025] Insert the second insertion rod 502 into the second slot 501. The airbag 503, fixed at the bottom of the second insertion rod 502, will form a barrier under the counterweight plate body 1. Because the airbag 503 is soft, it will not cause injury to people or objects when the roller shutter door descends. When the door is open, if a tall vehicle or cargo hits the bottom of the counterweight plate body 1, the airbag 503 can also prevent the counterweight plate body 1 from scratching the vehicle or cargo. When the door is closed, if it encounters an uneven ground, the airbag 503 will deform due to compression, thus better conforming to the ground, making the door close more securely and providing better sealing.

[0026] like Figure 1 and Figure 2 As shown, the counterweight plate body 1 has two slots 506 inside, and the two slots 506 are located on both sides of slot 2 501. A rod 507 is slidably inserted into each of the two slots 506. The two rods 507 are fixedly connected to the same protective cloth 508. The protective cloth 508 surrounds the airbag 503 and can protect the airbag 503, effectively preventing the airbag 503 from being damaged and losing its effectiveness.

[0027] like Figure 2 and Figure 4 As shown, a counterweight assembly 6 is installed inside the counterweight plate body 1. The counterweight assembly 6 includes several mounting slots 601 opened in the middle of one side outer wall of the counterweight plate body 1. A counterweight plate piece 602 is slidably inserted into each of the mounting slots 601. Two connecting pieces 603 are provided on the outside of each of the counterweight plate pieces 602.

[0028] The inner wall of the counterweight plate body 1 near the counterweight plate piece 602 is provided with several equally spaced support grooves 604, and one end of several counterweight plate pieces 602 is slidably inserted into several support grooves 604.

[0029] The curtain 4 may expand and increase in weight by 5% to 10% in a high-temperature environment. At this time, the bolts of the connecting piece 603 and the counterweight plate body 1 can be removed, and the counterweight plate 602 can be taken out from the mounting groove 601, thereby reducing the overall mass of the counterweight plate body 1, reducing the load on the roller shutter door drive, reducing energy consumption, and improving practicality.

[0030] like Figure 3 As shown, the airbag 503 is equipped with a microwave radar sensor, and the sensor is equipped with a power supply module (IWR6843ISK-ODS can penetrate non-metallic materials and is sensitive to moving objects) and a Bluetooth module (using the 2.4GHz ISM band and adopting frequency hopping spread spectrum (FHSS) technology to distribute data to 79 frequency points for transmission to reduce interference). The power supply module is equipped with a lithium manganese dioxide button battery.

[0031] If the sensor detects a person or object below the door, the roller shutter will stop descending, which helps improve the safety of the roller shutter. If the battery that powers the sensor needs to be replaced, the air injection head 505 can be twisted to move it out of the mounting ring 504. At this time, a certain space will be formed inside the mounting ring 504, and the operator can pass through the space to perform the battery replacement operation.

[0032] like Figure 1 and Figure 2 As shown, the counterweight plate body 1 has a slot 2 inside, and the slot 2 is located at the top of the counterweight plate body 1. A rod 3 is slidably inserted into the slot 2, and a curtain 4 is fixedly connected to the top of the rod 3, making the installation of the curtain 4 convenient.

[0033] like Figure 1 and Figure 2 As shown, the main body 1 of the counterweight plate is made of aluminum alloy, which ensures that the overall strength of the main body 1 is sufficient while not having too high a mass, making it easy to adjust its mass.

[0034] This utility model provides a novel structure for a counterweight plate of a roller shutter door, and its specific working principle is as follows:

[0035] When the device is in operation, the second insertion rod 502 is inserted into the second slot 501. The airbag 503, fixed at the bottom of the second insertion rod 502, forms a barrier below the counterweight plate body 1. Because the airbag 503 is soft, it will not cause injury to people or objects when the roller shutter door descends. When the door is open, if a tall vehicle or cargo hits the bottom of the counterweight plate body 1, the airbag 503 can also prevent the counterweight plate body 1 from scratching the vehicle or cargo. When the door is closed, if it encounters uneven ground, the airbag 503 will deform due to compression, thus better conforming to the ground, making the door close more securely and providing better sealing. The sensor installed inside the mounting ring 504 will stop the roller shutter door from descending if it detects a person or object below the door, which helps to improve the safety of the roller shutter door. For safety, if it is necessary to replace the battery that powers the sensor, the air injection head 505 can be twisted to move it out of the mounting ring 504. At this time, a certain space will be formed inside the mounting ring 504, and the operator can pass through the space to perform the battery replacement operation. The curtain 4 may expand and increase in weight by 5% to 10% in a high-temperature environment. At this time, the bolts between the connecting piece 603 and the counterweight plate body 1 can be removed, and the counterweight plate 602 can be taken out from the mounting groove 601, thereby reducing the overall weight of the counterweight plate body 1, reducing the load on the roller shutter door drive, reducing energy consumption, and improving practicality.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
