Description

Technical Field

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

[0002] Chains are generally metal links or rings, mostly used for mechanical transmission and traction. They are used to obstruct traffic (such as in streets, river or harbor entrances), and in mechanical transmission. Chains include four main series: transmission chains; conveyor chains; traction chains; and special-purpose chains. Chains can be further divided into short-pitch precision roller chains; short-pitch precision roller chains; heavy-duty transmission bent plate roller chains; chains for cement machinery; plate chains; and high-strength chains. Some high-strength chains are used on river railings to prevent pedestrians from falling into the water.

[0003] In existing technologies, when storing multiple chains, the chains are easily tangled when stacked together. Once tangled, they are difficult to untangle, reducing the efficiency of storage and taking up a lot of space. Therefore, we have introduced a foldable chain storage and retrieval device. Utility Model Content

[0004] The purpose of this invention is to provide a foldable chain storage and retrieval device that facilitates the storage and retrieval of multiple foldable chains, occupies little space, has high storage and retrieval efficiency, and prevents multiple chains from getting tangled, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A foldable chain storage device includes a housing with an opening on one side, and further includes:

[0007] A winding shaft, rotatably mounted inside the housing, is used to wind multiple chains;

[0008] The motor is located on the side wall of the housing. The output end of the motor passes through the housing and is fixedly connected to the winding shaft, and is used to drive the winding shaft to rotate.

[0009] The partitions, a plurality of which are evenly and fixedly disposed within the housing, are used to prevent the chains from tangling.

[0010] The locking mechanism includes a fixing plate and a locking unit. The fixing plate is fixedly mounted on the winding shaft between multiple partitions and is used to quickly lock the chain end to the winding shaft.

[0011] The pressing mechanism, including a pressing unit and a pressing plate, is located on the upper side of the housing between the partitions and is used to limit the movement of the stored chain.

[0012] As a further embodiment of this utility model, the locking unit includes a movable plate with a through hole in the middle. The movable plate is slidably mounted on the winding shaft at one side of the fixed plate. A locking rod is symmetrically fixed on the side of the movable plate near the fixed plate. The side wall of the fixed plate is provided with a locking groove that cooperates with the locking rod.

[0013] The winding shaft has a strip-shaped hole on its shaft wall, and a fixing rod is slidably disposed in the strip-shaped hole. The fixing rod is slidably disposed in the strip-shaped hole, and both ends of the fixing rod are fixedly connected to through holes. A first spring is fixedly disposed on the side of the fixing rod away from the fixing plate.

[0014] As a further embodiment of this utility model, the pressing unit includes a sliding rod and a circular block. The upper side of the housing is provided with a cavity at the locking mechanism, and the lower side of the cavity is provided with a sliding hole. The sliding rod is slidably disposed in the sliding hole, and the lower end of the sliding rod is fixedly connected to the pressing plate.

[0015] The circular block is fixedly mounted on the upper end of the slide bar, and a second spring is fixedly mounted on the upper end of the circular block.

[0016] As a further embodiment of this invention, the diameter of the circular block is larger than the diameter of the sliding hole, which is used to prevent the sliding rod from disengaging from the sliding hole.

[0017] As a further embodiment of this invention, the lower pressure plate is configured as an arc-shaped plate, which improves the limiting effect on the chain.

[0018] As a further embodiment of this invention, the end of the locking rod that mates with the locking groove is chamfered to facilitate the locking rod engaging with the locking groove.

[0019] As a further embodiment of this utility model, a wedge-shaped block is fixedly provided on the lower side of the shell opening between the two partitions.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This foldable chain storage and retrieval device comprises a winding shaft, a fixed plate, a lower pressure plate, a housing, a partition, a motor, a wedge block, a slide bar, a second spring, a circular block, a first spring, a movable plate, a locking rod, and a fixed rod. Pushing the movable plate to the right causes it to slide on the winding shaft, which in turn causes the fixed rod to slide within a slotted hole. The fixed rod then compresses the first spring, hooking one end of the chain onto the locking rod. Releasing the movable plate allows the first spring to push the fixed rod, which, through the movable plate, causes the locking rod to engage in a locking groove. Starting the motor causes the winding shaft to rotate clockwise, and the locking mechanism winds the chain around the winding shaft. The second spring pushes the circular block downwards, which, through the slide bar, causes the lower pressure plate to press against the chain. This facilitates the storage and retrieval of multiple foldable chains, occupies little space, has high efficiency, and prevents chains from tangling. Attached Figure Description
