Description

Technical Field

[0001] This utility model relates to the field of chain storage technology, and in particular to a storage device. Background Technology

[0002] Industrial overhead doors are typically installed in workshops' integrated power stations and warehouses. These doors open and close very quickly, reducing waiting time for vehicles and personnel during logistics and improving efficiency. Furthermore, fire-resistant overhead doors can prevent the spread of flames and smoke for a certain period, buying time for personnel evacuation and fire rescue.

[0003] Normally, the lifting door is controlled by an electric actuator. However, in the event of a power outage, a manual release device is required to control the lifting door. The manual operating chain is a key component of the manual release device. The manual operating chain is a circular chain consisting of an adjacent first chain and a second chain. The first chain is used to open the lifting door, and the second chain is used to close it. However, because the manual operating chain usually hangs freely on one side of the lifting door, it not only occupies space during production and transportation, but also easily obstructs personnel and vehicles, which is inconsistent with on-site regulations. Furthermore, multiple chains are prone to tangling and knotting, making them difficult to separate quickly in emergencies. This prevents operators from opening and closing the lifting door in a timely manner, posing a significant safety hazard. Utility Model Content

[0004] The purpose of this invention is to solve the technical problems of the first and second chains, which are freely suspended on the side of the lifting door, not only occupying space and easily obstructing the passage of personnel and vehicles, but also easily becoming entangled and difficult to separate quickly. This invention provides a storage device that can separately store the first and second chains, both to store excess chain length, reduce space occupation, prevent obstruction of personnel and vehicles, and prevent the two chains from becoming entangled.

[0005] To solve the above-mentioned technical problems, an embodiment of this utility model discloses a storage device for storing a dangling chain, the dangling chain including a first chain and a second chain, comprising:

[0006] The housing has a receiving cavity inside, and the receiving cavity has an opening at the top;

[0007] A limiting part is provided inside the receiving cavity, and the limiting part encloses and forms a first cavity and a second cavity with openings at the top and bottom within the receiving cavity; the first cavity is used to receive the first chain, and a first notch is provided on the side wall of the first cavity, penetrating the limiting part in a vertical direction; the second cavity is used to receive the second chain, and a second notch is provided on the side wall of the second cavity, penetrating the limiting part in a vertical direction.

[0008] When it is necessary to store the drooping chain, the operator first places the lower part of the drooping chain into the receiving cavity through the opening above the receiving cavity, then passes the first chain through the first notch and puts it into the first cavity, and passes the second chain through the second notch and puts it into the second cavity, thus completing the storage of the chain.

[0009] By employing the above technical solution, the shell effectively houses the chain, preventing it from occupying space due to its excessive length when hanging freely, thus avoiding obstruction of transport personnel and vehicles. Furthermore, the limiting part divides the receiving cavity into independent first and second cavities, allowing the first and second chains to be stored separately and preventing the two chains from tangling.

[0010] Optionally, the dangling chain is positioned close to the wall, and the housing is mounted on the wall. The housing includes an identification plate, which is parallel to the wall and located on the side away from the wall. The outer surface of the identification plate is provided with a first identification corresponding to the first cavity and a second identification corresponding to the second cavity.

[0011] By adopting the above technical solution, by setting the markings corresponding to the first cavity and the second cavity on the outer surface of the marking plate, the operator can quickly identify what kind of chain is contained in the two cavities, thus avoiding confusion and pulling the wrong chain.

[0012] Optionally, the limiting part includes:

[0013] The partition extends perpendicularly to the signboard, and one end of the partition is connected to the inner surface of the signboard.

[0014] The connecting plate is parallel to the signboard, and its middle part is connected to the other end of the partition.

[0015] The first limiting plate is located between the connecting plate and the marking plate and is parallel to the partition. One end of the first limiting plate is connected to one end of the connecting plate. The marking plate, the partition, the connecting plate and the first limiting plate enclose a first cavity. The other end of the first limiting plate is spaced a certain distance from the inner surface of the marking plate to form a first notch.

[0016] The second limiting plate is located between the connecting plate and the marking plate and is parallel to the partition. One end of the second limiting plate is connected to the other end of the connecting plate. The marking plate, the partition, the connecting plate and the second limiting plate enclose a second cavity. The other end of the second limiting plate is spaced a certain distance from the inner surface of the marking plate to form a second notch.

[0017] By adopting the above technical solution, and by setting a limiting plate and a notch, it is ensured that the chain can be easily put in and taken out through the notch, while the limiting plate located on the side of the chain greatly limits the possibility of the chain accidentally coming off, thus improving the reliability of storage.

[0018] Optionally, the distance between the first limiting plate and the marking plate is greater than or equal to the width of the first chain, and the distance between the second limiting plate and the marking plate is greater than or equal to the width of the second chain.

[0019] Optionally, the housing includes:

[0020] Base plate,

[0021] The first side plate is perpendicular to the bottom plate, and the bottom of the first side plate is connected to one end of the bottom plate;

[0022] The second side plate is arranged opposite to the first side plate, and the bottom of the second side plate is connected to the other end of the bottom plate;

[0023] The signboard is perpendicular to the first side panel, the second side panel, and the bottom panel, respectively. The signboard is located between the first side panel and the second side panel, with both ends of the signboard connected to the first side panel and the second side panel, respectively, and the bottom of the signboard connected to the bottom panel.

[0024] By adopting the above technical solution, the shell structure without a backplate is more aesthetically pleasing and can save manufacturing costs.

[0025] Optionally, the bottom of the limiting part is spaced a certain distance from the base plate.

[0026] By adopting the above technical solution, there is a certain amount of space between the bottom of the limiting part and the base plate, which can better accommodate the first chain and the second chain.

[0027] Optionally, the storage device also includes a drain hole located on the base plate.

[0028] By adopting the above technical solution, when there is water accumulation inside the housing, the drainage hole can drain the water inside the housing in a timely manner, thus preventing the chain from rusting.

[0029] Optionally, ear plates are connected to both the first side plate and the second side plate. The ear plates are perpendicular to the first side plate, the second side plate and the bottom plate, respectively, and are used to connect to the wall.

[0030] Optionally, the ear plate is provided with through holes for bolts to pass through so that the housing can be connected to the wall.

[0031] Using the above technical solution, the bolted connection between the ear plate and the wall provides higher fixing strength, resists external impacts, and can bear a higher weight of the chain.

[0032] Optionally, both the housing and the limiting part are made of stainless steel.

[0033] By adopting the above technical solution, the shell and limiting part are made of stainless steel to increase their strength, making them less prone to damage and corrosion during use, thereby extending the service life of the storage device. Attached Figure Description

[0045] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0046] See Figure 1 and Figure 3 The present invention discloses a storage device for storing a dangling chain, the dangling chain including a first chain and a second chain, and the storage device including a housing 1 and a limiting part 2.

[0047] The housing 1 has a receiving cavity 11 with an opening at the top. A limiting part 2 is disposed within the receiving cavity 11, forming a first cavity 232 and a second cavity 242 with openings at both the top and bottom within the receiving cavity 11. Both the first cavity 232 and the second cavity 242 extend vertically. The first cavity 232 is used to receive a first chain, and a first notch 231 extending vertically through the limiting part 2 is provided on the side wall of the first cavity 232. The second cavity 242 is used to receive a second chain, and a second notch 241 extending vertically through the limiting part 2 is provided on the side wall of the second cavity 242.

[0048] When it is necessary to store the drooping chain, the operator first places the lower part of the drooping chain into the receiving cavity 11 through the opening above the receiving cavity 11, then passes the first chain through the first notch 231 and puts it into the first cavity 232, and passes the second chain through the second notch 241 and puts it into the second cavity 242, thus completing the storage of the chain.

[0049] By adopting the above technical solution, the housing 1 effectively stores the chain, preventing the chain from occupying space due to its excessive length when hanging freely, which could easily obstruct transport personnel and vehicles. Furthermore, the limiting part 2 divides the receiving cavity 11 into independent first cavities 232 and second cavities 242, allowing the first chain and the second chain to be stored separately, preventing the two chains from tangling together.

[0050] Furthermore, in environments where lifting doors are used, the dangling chain is typically positioned close to the wall. In this case, housing 1 is mounted on the wall. See also Figure 1 The housing 1 includes an identification plate 12, which is parallel to the wall and located on the side away from the wall. The outer surface of the identification plate 12 has a first identification 121 corresponding to the first cavity 232 and a second identification 122 corresponding to the second cavity 242. For example, the first identification 121 is an open identification, and the second identification 122 is a closed identification; the first identification 121 and the second identification 122 are affixed to the outer surface of the identification plate 12. By providing identifications corresponding to the first cavity 232 and the second cavity 242 on the outer surface of the identification plate 12, operators can quickly identify what type of chain is contained in the two cavities, avoiding operational confusion and pulling the wrong chain.

[0051] Specifically, see Figure 1 and Figure 3 The housing 1 also includes a base plate 13, a first side plate 14, and a second side plate 15. Both the first side plate 14 and the second side plate 15 are perpendicular to the base plate 13, with the bottom of the first side plate 14 connected to one end of the base plate 13. The second side plate 15 is opposite to the first side plate 14, with its bottom connected to the other end of the base plate 13. A label plate 12 is perpendicular to the first side plate 14, the second side plate 15, and the base plate 13, respectively. The label plate 12 is positioned between the first side plate 14 and the second side plate 15, with both ends connected to the first side plate 14 and the second side plate 15, and its bottom connected to the base plate 13. When the housing 1 is installed on a wall, the base plate 13, the first side plate 14, the second side plate 15, the label plate 12, and the wall together form a receiving cavity 11. For example, the label plate 12 is 12cm long, the first side plate 14 and the second side plate 15 are both 6cm long, and the housing 1 is 14cm high. The shell structure without a backplate is more aesthetically pleasing and can save on manufacturing costs.

[0052] Specifically, see Figure 2 and Figure 3Each of the first side plate 14 and the second side plate 15 is connected to a lug plate 16. The lug plate 16 is perpendicular to the first side plate 14, the second side plate 15, and the bottom plate 13, respectively, and is used to connect to the wall. For example, the lug plate 16 has a through hole 161 for bolts to pass through, so that the housing 1 is connected to the wall. The bolted connection between the lug plate 16 and the wall provides higher fixing strength, resists external impact, and can bear a higher mass of the chain.

[0053] Further, see Figure 4 The limiting part 2 includes a partition 21, a connecting plate 22, a first limiting plate 23, and a second limiting plate 24.

[0054] See Figure 2 and Figure 3 The partition 21 extends perpendicularly to the label plate 12, and one end of the partition 21 is connected to the inner surface of the label plate 12. The connecting plate 22 is parallel to the label plate 12, and the middle part of the connecting plate 22 is connected to the other end of the partition 21. For example, the partition 21 is welded to the housing 1, and the length of the connecting plate 22 is 10cm.

[0055] The first limiting plate 23 is disposed between the connecting plate 22 and the marking plate 12 and is parallel to the partition plate 21. One end of the first limiting plate 23 is connected to one end of the connecting plate 22. The marking plate 12, the partition plate 21, the connecting plate 22, and the first limiting plate 23 enclose a first cavity 232. The other end of the first limiting plate 23 is spaced a certain distance from the inner surface of the marking plate 12 to form a first notch 231. For example, the length of the first limiting plate 23 is 2cm, and the distance between the first limiting plate 23 and the first side plate 14 is 1cm.

[0056] The second limiting plate 24 is disposed between the connecting plate 22 and the marking plate 12 and is parallel to the partition plate 21. One end of the second limiting plate 24 is connected to the other end of the connecting plate 22. The marking plate 12, the partition plate 21, the connecting plate 22, and the second limiting plate 24 enclose a second cavity 242. The other end of the second limiting plate 24 is spaced a certain distance from the inner surface of the marking plate 12 to form a second notch 241. For example, the length of the second limiting plate 24 is 2cm, and the distance between the second limiting plate 24 and the second side plate 15 is 1cm. The first limiting plate 23, the second limiting plate 24, and the connecting plate 22 are made by an integral bending process, and the partition plate 21 and the connecting plate 22 are fixedly connected by welding.

[0057] By setting a limiting plate and a notch, the chain can be easily put in and taken out through the notch, while the limiting plate located on the side of the chain greatly limits the possibility of the chain accidentally coming off, thus improving the reliability of storage.

[0058] Specifically, the distance between the first limiting plate 23 and the marking plate 12 is greater than or equal to the width of the first chain, and the distance between the second limiting plate 24 and the marking plate 12 is greater than or equal to the width of the second chain. For example, the width of both the first and second chains is 0.8 cm, the distance between the first limiting plate 23 and the marking plate 12 is 1 cm, and the distance between the second limiting plate 24 and the marking plate 12 is 1 cm. The inventors discovered that when the distance between the limiting plate and the marking plate 12 is 1 cm, the chain can smoothly enter and exit while ensuring that it cannot naturally detach.

[0059] Specifically, see Figure 2 The bottom of the limiting part 2 is spaced a certain distance from the base plate 13. This design provides a certain accommodating space between the bottom of the limiting part 2 and the base plate 13. When the first chain and the second chain are stored, the first chain and the second chain pass through the first cavity 232 and the second cavity 242 from top to bottom, respectively, and the lower parts of the first chain and the second chain enter the accommodating space below the base plate 1. Since the cross-sectional area of ​​the accommodating space is larger than the cross-sectional area of ​​the first cavity 232 and the second cavity 242, the space is larger and can better accommodate the first chain and the second chain. In addition, this design can also be used to store loop-shaped dangling chains (i.e., the bottoms of the first chain and the second chain are connected), so that the connecting part of the bottom of the first chain and the second chain is accommodated in the accommodating space below the base plate 13.

[0060] Specifically, see Figure 3 The storage device also includes a drain hole 131, which is located on the base plate 13. When water accumulates inside the housing 1, the drain hole 131 can drain the water from the housing 1 in a timely manner, preventing the chain from rusting.

[0061] Specifically, both the housing 1 and the limiting part 2 are made of stainless steel. By making the housing 1 and the limiting part 2 of stainless steel, the strength of the housing 1 and the limiting part 2 is increased, making them less prone to damage and corrosion during use, thereby extending the service life of the storage device.

[0062] When installing the storage device, the installation location needs to be determined. To accommodate the average height of operators and facilitate operation, the top of the installed storage device should be 150cm above the ground. Secure the storage device to the wall near the dangling chain using bolts.

[0063] When it is necessary to store the dangling chain, the operator inserts the lower part of the dangling chain into the housing 1 through the upper opening of the receiving cavity 11. Then, the first chain section near the limiting part 2 is inserted into the first cavity 232 through the first notch 231, and the second chain section near the limiting part 2 is inserted into the second cavity 242 through the second notch 241. When the chain is in its natural dangling state, the side walls of the first cavity 232 and the second cavity 242 can limit the first chain and the second chain, preventing the chain from coming out of the first cavity 232 and the second cavity 242, thus completing the storage of the chain.

[0064] When it is necessary to control the opening or closing of the lifting door via the drooping chain, the operator can quickly identify the target chain through the first mark 121 and the second mark 122 and pull the target chain directly without having to remove the chain from the limiting part 2.

[0065] The storage device provided by this utility model has a simple structure and is easy to use. It can fix different chains in sections, avoiding the situation where multiple chains become tangled and knotted. In addition, the outer surface of the storage device is marked with corresponding marks for the storage position of each chain, so that operators can quickly identify the target chain and avoid operational confusion.

[0066] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
