Description

[Detailed description of the invention] The present invention is designed to easily connect and release a large number of carts used when storing and continuously thawing frozen products such as fish and livestock meat. This invention relates to a coupling device for fixing a trolley.

Generally, fish meat, livestock meat, etc. are frozen at ultra-low temperatures to maintain freshness, and are thawed appropriately during the distribution process from retail stores to consumers.

Therefore, the frozen items to be thawed are stored in a box-shaped trolley that has multiple shelves and openings on opposite sides, and this trolley is connected to the thawing chamber of a predetermined thawing device. Thawing, refrigeration, and sterilization are performed by circulating temperature- and humidity-controlled air at appropriate temperatures.

However, when a large number of the above-mentioned carts are connected and stored in a thawing warehouse, if there is a gap between the carts, the carts may rattle or the circulating air circulation path may become incomplete, resulting in air leakage. There are disadvantages such as uneven thawing and decreased thawing effect.

Therefore, conventionally, in order to fix the connection between the bogies when the above bogies are connected, wheels with stoppers attached to the front or rear wheels of the running wheels attached to the bottom of the bogies have been used. This meant that the trucks were often used with gaps left between the trucks.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to form a duct-like circulation passage by connecting the openings of box-shaped carts that have multiple shelves and openings on opposite sides. It is an object of the present invention to provide a coupling device for fixing a carriage, which is configured so that connection and release operations between the respective carriages can be easily performed with a single touch.

In order to achieve the above object, the present invention provides a box-shaped trolley with multiple shelves for storing items to be thawed, and has openings on both front and rear opposing sides. a handle pivotally supported via a bracket on both sides of the other open end of the dolly; an operating shaft provided on the handle at a distance from its pivot point; A guide protruding between the other side opening edge of the cart and the pivot point of the handle and a hook that engages with the grip are formed at the tip, and the rear end is pivoted on the operating shaft and The grip is attached to one of the carriages of the articulated carriage with an opening communicating with the clamp, and the clamp is attached so that the middle part slides on the guide and the hook at the tip moves when the handle is rotated. The grip is formed to protrude toward the other truck so that it can be engaged with a hook at the tip of a clamp provided on the other truck.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a trolley 1 showing an embodiment of the present invention.
This is a box-shaped cart in which removable and removable shelves 1 ₁ to 1n for storing items to be thawed are installed in multiple stages, and openings are formed on both opposing front and rear sides. A pair of left and right fixed wheels 2, 2, which are running wheels, and a swivel wheel (caster) 3, 3 with a rotating fixed stopper are mounted on the bottom surface of the truck 1. In addition, in order to easily move the cart 1 and carry it out and carry it into the thawing warehouse, grips 4 are provided on both sides of one side of the open end and serve as connecting guides for the cart 1 that is subsequently connected. , 4 are fixed.

On the other hand, clamp devices 5, 5, which are connected via the grips 4, are fixed to both sides of the truck 1 opposite to where the grips 4, 4 are attached.

The clamping device 5 has a fulcrum 7 on the bracket 6.
A U-shaped handle 8 is rotatably supported via the handle, and a clamp 9 is attached to and detached from the grip 4.
and an operating shaft 10 with one side of the clamp 9 rotatably supported on a handle 8. When the handle 8 is operated, a hook 9a formed at the tip of the clamp 9 is automatically engaged with the grip 4. A guide 11 is provided at a predetermined position so that it can be removed.

Therefore, as described above, the coupling device for the carriage 1 consisting of the grip 4 and the clamp device 5 is set in advance by operating the handle 8 as shown in FIG. If the handle 8 is slowly rotated from the point to the point side, the clamp 9 will connect to the guide 1.
1, the hook 9a is engaged with the grip 4. When the handle 8 is positioned at the point, the clamp 9 is located inside the fulcrum 7 and is locked by the principle of the toggle mechanism.

In addition, when canceling the connection between carts 1 and 1,
All that is required is to rotate the handle 8 from point to point, and the operation of connecting and disengaging the carts 1, 1 is performed by one-touch operation of the handle 8.

In addition, when working with the trolley 1 near a wall such as inside a thawing warehouse, in order to facilitate the operation of the handle 8, a remote control handle 13 as shown in FIG. The connecting rod 16 can be attached to the operating shaft 10 of the clamping device 5. In addition, in order to keep the moving trajectory of the clamp 9 constant, the clamp 9 is attached to the guide 11.
A flat ring body (not shown) through which the ring is inserted may be freely pivoted.

As explained above in detail, the coupling device for fixing a bogie according to the present invention has a grip that also serves as a connecting guide for the bogie, and an operating shaft of the handle that is pivotally supported via the fulcrum of the bracket. It has a simple structure consisting of a clamp device which is pivotally supported by a clamp having a hook, and the cart and the cart can be easily and airtightly connected with one touch.

In addition, since the trolley connected to the trolley also uses the grip as a connecting guide, there is no need for a special receiving member.Furthermore, by providing a guide for the clamp, the hook of the clamp can be attached to the grip simply by operating the handle. Since it is automatically engaged and disengaged, it is easy to operate, and when the carts are connected, problems such as gaps between the carts due to vibration and rattling are eliminated.
There is no waste in the amount of circulated air, and there are practical effects such as cost reduction. The present invention is not limited to thawing, but can also be used for various purposes such as ice-temperature storage, refrigeration, and drying.
