Technical Field:

[0001] The utility model relates to the technical field of air duct packaging devices, and more specifically to a stacking and bearing device for air ducts with flanged mounting plates. Background Art:

[0002] An air duct is a component in a fan. At present, the bottom of some air ducts is bent into a rectangular panel. Generally, the air ducts are stacked above a pallet by using the panel, and then the stacked air ducts and the pallet are bundled and fixed together by a packing belt. However, according to the feedback from the purchaser, the panels and tops of the air ducts are deformed to varying degrees, and the paint surfaces at the above-mentioned parts are also worn. After analysis, it is mainly because the vibration during transportation causes the adjacent air ducts to move relatively, resulting in deformation and paint surface damage. Therefore, it is necessary to design a packaging structure that can separate the air ducts and can also provide shock absorption. Content of the Utility Model:

[0003] The purpose of the utility model is to provide a stacking and bearing device for air ducts with flanged mounting plates aiming at the deficiencies of the prior art. It can bear and separate the air ducts, position the air ducts while providing shock absorption, and avoid collisions between the air ducts.

The lower side of the air duct is formed with a horizontally rectangular panel. The outer side of the panel is bent to form an upward flange. Above the four corners of the pallet, there are respectively several vertically distributed buffer pads, and the buffer pads are arranged on the upper and lower sides of the panel.

[0005] The buffer pad includes a rectangular block. On the upper side of the block close to the side of the pallet, an L-shaped upper baffle is formed. Between the side wall of the upper baffle and the upper end surface of the block, a rectangular placement groove is formed.

[0021] Example: As shown in Figures 1 to 5 a stacking and loading device for an air guide cylinder with a folded-edge mounting plate, including a rectangular tray 1. Above the tray 1, there is a vertically distributed air guide cylinder 2. A horizontally rectangular panel 21 is formed on the lower side of the air guide cylinder 2. An upward folded edge 22 is formed by bending the outer side of the panel 21. Above the four corners of the tray 1, there are several vertically distributed buffer cushion blocks 3 respectively. The buffer cushion blocks 3 are arranged on the upper and lower sides of the panel 21;

[0022] The buffer cushion block 3 includes a rectangular block body. An L-shaped upper edge 31 is formed on the upper side of the block body near the side of the tray 1. A rectangular placement groove a is formed between the side wall of the upper edge 31 and the upper end face of the block body. A positioning convex block 32 is formed on the lower end face of the block body, which is opposite to the placement groove a. A positioning card slot 33 extending upward is formed on the side wall of the positioning convex block 32;

[0023] The four corners of the panel 21 are respectively inserted into the placement groove a of the buffer cushion block 3. The lower end face of the panel 21 abuts against the bottom surface of the placement groove a, and the upper end face abuts against the lower end face of the positioning convex block 32. The placement groove a and the positioning convex block 32 are respectively the structures on the upper and lower buffer cushion blocks 3 of the panel 21; the folded edges 22 of the panel 21 are respectively inserted into the positioning card slots 33 of the buffer cushion block 3;

[0024] A rectangular protective cover plate 5 is provided above the air guide cylinder 2. The protective cover plate 5 abuts against the buffer cushion block 3. Packing belts 4 are respectively arranged on both sides of the tray 1. The protective cover plate 5, the buffer cushion block 3, the air guide cylinder 2 and the tray 1 are fixedly connected together by the packing belts 4; the four corners of the protective cover plate 5 are arranged in the placement groove a of the top buffer cushion block 3, and the depth of the placement groove a is equal to the thickness of the protective cover plate 5.

[0025] The length of the side of the panel 21 on the air guide cylinder 2 is less than the length of the side of the tray 1, and the sides of each side of the tray 1 are equal.

[0026] The height of the buffer cushion block 3 is greater than the height of the air guide cylinder 2. Furthermore, there is a gap between the air guide cylinders 2, which can achieve the separation of the air guide cylinders 2. The buffer cushion block 3 is made of a foam buffer cushion block, which is convenient to manufacture and has a low manufacturing cost.

[0027] The groove width of the positioning card slot 33 on the buffer cushion block 3 is equal to the thickness of the folded edge 22, and the depth of the positioning card slot 33 is not less than the width of the folded edge 22.

[0028] The side wall of the buffer cushion block 3 near the side of the tray 1, the side wall of the tray 1 and the side wall of the protective cover plate 5 are all within the same rectangular cylindrical surface.

[0029] The width of the packing belt 4 is less than the width of the buffer cushion block 3.

[0030] Working principle: The utility model is a stacking and bearing device for an air guide cylinder with a folded-edge mounting plate. The stacking and bearing device is composed of a tray 1, a buffer cushion block 3, a protective cover plate 5 and a packing belt 4. The main technical points are located on the buffer cushion block 3. The upper and lower adjacent buffer cushion blocks 3 can cooperate with each other based on the placement groove a and the positioning convex block 32. When supporting the air guide cylinder 2, it can limit the position of the air guide cylinder 2 and can separate the upper and lower adjacent air guide cylinders 2 to avoid collision between the air guide cylinders 2 caused by vibration;

[0031] Moreover, the buffer cushion block 3 is made of a foam block and has a shock-absorbing effect. When using the packing belt 4 for packing, it can be elastically pre-tightened, so that the buffer cushion block 3 is elastically pressed on the panel 21 of the air duct 2. During transportation, it can absorb shocks and prevent scattering due to large vibrations.

[0032] Meanwhile, during the packing process, using a wider and tighter packing belt 4 will not cause the air duct 2 to deform due to the excessive tightness of the packing belt 4 (mainly because the buffer cushion block 3 is not provided and the packing belt 4 acts directly on the air duct 2), which facilitates the packing operation.

[0033] The above embodiments are used to illustrate the present invention by way of example, rather than to limit the present invention. Any person skilled in the art can modify the above embodiments without departing from the spirit and scope of the present invention. Therefore, the scope of the rights protected by the present invention shall be as set forth in the claims of the present invention.
