As shown in fig. 3 and 4, the hook 230 of the present application includes a hook body 231. Optionally, the first end of the hook body 231 is connected to the second end of the lifting rope 220, for example, the first end of the hook body 231 is provided with a connecting hole, and the second end of the lifting rope 220 is provided with a hanging ring, and the hanging ring is inserted into the connecting hole, so as to connect the hook body 231 and the lifting rope 220, or connect the two by any other suitable method.

The hook 230 of the present application further includes a hook 232 disposed at a second end of the hook 230 (i.e., a second end of the hook body 231) and protruding toward a first side of the hook body 231. Alternatively, the hook body 231 and the hook body 232 may be integrally formed. When lifting the tray 300, the hook 232 abuts a portion of the tray 300, thereby applying an upward force to the tray 300 by the hook, so that the tray 300 can be lifted.

In one example, the hook 230 of the present application further includes a retaining member 233 slidably disposed on a second side of the hook body 231, wherein the first side and the second side are disposed opposite to each other, and the retaining member 233 is configured to: can slide between the first end of the hook 230 (i.e. the first end of the hook body 231) and the second end of the hook in the axial direction of the hook body, when lifting the tray, the hook 230 is inserted into the hanging hole 310 of the tray, the hook body 232 abuts against the part of the tray 300 outside the hanging hole 310, and the anti-drop member 233 is inserted into the hanging hole 310. The anti-slip member 233 prevents the hook 230 from being swung in the hanging hole 310, and prevents the hook 230 from being disengaged from the hanging hole 310.

The retaining member 233 may be any suitable sliding structure, such as a slide block, etc., and may be connected to the second side of the hook body 231 by a slide way or a slide rail, etc., which extends in a direction substantially corresponding to the axial direction of the hook body 231, so that the retaining member 233 slides between the first end and the second end of the hook on the second side of the hook body 231, in one example, the second side of the hook body 231 may further be provided with a limiting structure to limit the sliding position of the retaining member 233, and to prevent the retaining member 233 from being released from the hook body 231.

After the installation is completed, for example, as shown in fig. 4, when the lifting structure lifts the tray, the anti-drop member 233 may be slid to the second end 231 of the hook body manually or by using its own weight and is inserted into the hanging hole 310, so as to prevent the hook body from shaking in the hanging hole 310, and thus the hook body can be stably hooked on a part of the tray outside the hanging hole, for example, a part of the bottom surface of the tray.

In one example, the radial dimension of the second end of the hook 230 (i.e., the sum of the radial dimensions of the hook body 232 and the hook body 231 to which it is attached) is less than the radial dimension of the lifting hole 310, such that the second end of the hook can pass out of the lifting hole 310.

In one example, the radial dimension of the portion of the hook body 231 located in the hanging hole 310 is smaller than the radial dimension of the hanging hole 310, and the sum of the radial dimension of the portion of the hook body 231 located in the hanging hole 310 and the thickness of the retaining member 233 is smaller than the radial dimension of the hanging hole 310 (the radial dimension is a diameter when the hanging hole is circular, and the radial dimension may be a width or a length when the hanging hole is square), so that the retaining member 233 can be slidably inserted into the hanging hole 310, wherein the thickness of the retaining member 233 is a dimension between a first surface of the retaining member 233 in contact with the hook body 231 and a second surface opposite to the first surface, and the radial dimension of the hook body 231 is a dimension between the first side and the second side, and the radial dimension may be a diameter when the hook body 231 is cylindrical. For example, the radial dimension of the second end of the hook 230 is greater than or equal to 16mm and less than or equal to 30 mm; the radial dimension of the hanging hole 310 is greater than or equal to 16.5mm and less than or equal to 30.5 mm; the thickness of the escape prevention member 233 is 4mm or more and 20.5mm or less. In one specific example, the second end of the hook 230 has a radial dimension (i.e., diameter) of 17.5mm, the diameter of the hanging hole 310 of the tray 300 is 18.0mm, the diameter of the hook 230 is less than the diameter of the hanging hole 310, and the hook 230 can be placed into the hanging hole 310.

In one example, the sum of the radial dimension of the second end of the hook and the thickness of the anti-slip member is greater than the radial dimension of the hanging hole, so that the hook body of the second end of the hook is in interference with the hanging hole to ensure that the hook does not slip, for example, the thickness of the anti-slip member is substantially 5.5mm, and when the anti-slip member is attached to the hook, the anti-slip member slides to the second end (namely, the bottom) of the hook due to the gravity action, so that the maximum diameter of the second end of the hook becomes 23.0mm, which is greater than the diameter 18.0mm of the hanging hole 310, and the interference is 5.0mm, so that the hook is ensured not to slip.

In one example, a threaded sleeve (not shown) is further disposed at the hanging hole 310 of the tray 300, at least a portion of the hook 230 is inserted into the threaded sleeve, and a space is provided between the hook 230 and an inner sidewall of the threaded sleeve, and the anti-dropping member 233 is configured to: can slide in the swivel nut, that is to say the interval has the size that is greater than the anticreep component between the inside wall of lifting hook and swivel nut.

The description of the hoisting structure of the present application has been completed so far, but it is understood that, in order to realize the hoisting of the pallet, a hoisting device may be further included, which may apply a pulling force to the support through, for example, a hook, etc., to thereby hoist the support, to transfer it, etc.

In conclusion, the technical effects of the utility model are that through the hoisting structure provided by the application, when the lifting hook is installed and connected with the lifting hole of the tray, the installation can be realized without too much installation space below the lifting hole, the installation is rapid and convenient, the operation is simple and efficient, and the connection between the lifting hook and the tray is safe and reliable.
