[0015] The utility model is further described in detail below through specific implementation methods:

[0016] Because the existing grain cooling unit has an integrated structure, the upper part is the indoor unit and the lower part is the outdoor unit. The indoor unit is responsible for the heat exchange between the indoor return air and the supply air. The control box 2 is mostly set on the outdoor unit side and is located below the indoor return air outlet. However, the indoor return air outlet is equipped with a flange 1 for easy installation. The edge of the flange 1 is relatively sharp. During the production process, when the operator is laying out the cables at the control box 2, it is easy for him to touch the edge of the flange 1 with his head, which may cause a safety hazard of head injury or scratches. In order to solve this problem, Figure 1 and Figure 2 As shown, an embodiment of the utility model proposes a jacket structure, which cooperates with the flange 1 at the air outlet of the grain cooling unit, and includes a jacket body 3, and the jacket body 3 is covered on the edge of the flange 1 along the circumferential direction of the edge of the flange 1.

[0017] The sheath structure includes a sheath body 3, which is wrapped around the edge of the flange 1 along the circumferential direction of the flange 1, thereby wrapping the sharp edge of the flange 1. Even if the operator touches it, there is no risk of injury, which greatly improves production safety.

[0018] like Figure 2 As shown, according to another embodiment of the utility model, the sheath structure, wherein the sheath body 3 is square; because the flange 1 is square, the shape of the sheath body 3 is adapted. If the shape of the flange 1 changes, the shape of the sheath body 3 can be adaptively adjusted.

[0019] The sheath body 3 is made of soft plastic, such as PVC soft plastic, etc., so that the sheath body 3 has a certain elastic potential energy, which can play a certain buffering role at the contact point between the head and the sheath body 3; at the same time, a certain elastic deformation can occur when the sheath body 3 is assembled or disassembled, and the assembly or disassembly of the sheath body 3 is more convenient.

[0020] Next, the structure of the sheath body 3 is further optimized. Figure 3 , Figure 4 as well as Figure 5 As shown, according to another embodiment of the utility model, a sheath structure is described, wherein the sheath body 3 includes a head guard 31 and a edging portion 32; wherein the cross-section of the head guard 31 is arc-shaped; the edging portions 32 are two and arranged in parallel and at intervals, and the two edging portions 32 are connected to the two ends of the insertion port of the head guard 31 in a one-to-one manner.

[0021] The head guard 31 is arc-shaped, and a cavity is formed therein for placing the edge of the flange 1. The shape design of the head guard 31 can reduce the force generated by the head when in contact, and has a good protective effect. The two edge parts 32 extend the contact area of ​​the sleeve body 3 when covering the flange 1, thereby improving the assembly stability of the sleeve body 3 on the flange 1.

[0022] Among them, the arc is a superior arc, so that the space in the cavity is relatively large, and the distance between the two edge parts 32 is relatively small; the edge of the flange 1 has a certain movable space in the cavity and fits tightly with the two edge parts 32, which can ensure the assembly stability and is beneficial to the assembly or disassembly efficiency of the sheath body 3.

[0023] In order to further improve the assembly stability of the sheath body 3, as Figure 4 and Figure 5 As shown, according to another embodiment of the present invention, the sheath structure, wherein the sheath body 3 has two ends and one of the edging portions 32 at the two ends is provided with at least one buckle 33 that cooperates with the flange 1.

[0024] In this embodiment:

[0025] A buckle 33 is provided on the edge portion 32 on the same side of both ends of the sheath body 3. After the sheath body 3 is mounted on the flange 1, the two buckles 33 are engaged with the flange 1 to improve the assembly stability of the sheath body 3.

[0026] Specifically, each of the buckles 33 is matched with a clamping hole 4 opened on the flange 1; that is, two clamping holes 4 are opened on the flange 1, and after the sheath body 3 is mounted on the flange 1, the two buckles 33 are correspondingly inserted into the two clamping holes 4 to be clamped and fixed.

[0027] In order to better enable the buckle to be inserted into or withdrawn from the corresponding clamping hole 4, another edge portion 32 at both ends of the sheath body 3 is provided with a clearance notch 5 for assembling the corresponding buckle 33. After the buckle 33 is inserted into the corresponding clamping hole 4, part of the buckle 33 passes through the clamping hole 4 and is placed in the clearance notch 5 to make way for the assembly of the buckle 33; the buckle 33 can also be withdrawn from the corresponding clamping hole 4 through the clearance notch 5, which is more convenient to operate.

[0028] Based on the above scheme:

[0029] Each of the buckles 33 includes a connecting rib 331 and a locking head 332; wherein, one end of the connecting rib 331 is connected to the corresponding edging portion 32 and is used to penetrate into the card hole 4 for adaptation; the cross-section of the locking head 332 gradually increases from one end thereof to the other end and the end with the larger cross-section is connected to the connecting rib 331 and forms a limited step.

[0030] The shape design of the locking head 332 facilitates the insertion of the locking head 332 into the corresponding card hole 4, and then passes through the corresponding card hole 4 to be placed in the corresponding clearance gap 5 and the connecting rib 331 is placed in the card hole 4 for adaptation, so that the limiting step formed by the locking head 332 and the connecting rib 331 limits the connecting rib 331 from withdrawing from the corresponding card hole 4, thereby improving the connection stability of the buckle 33 in the corresponding card hole 4.

[0031] The length of the large end of the locking head 332 can be 0.5cm-2cm larger than the diameter of the card hole 4, and because the buckle 33 is made of PVC soft plastic and has good elastic deformation ability, squeezing the locking head 332 can make it withdraw from the corresponding card hole 4.

[0032] like Figure 1 As shown, according to another embodiment of the utility model, a grain cooling unit includes an indoor unit located at the upper part and an outdoor unit located at the lower part, the indoor return air outlet is arranged on the outer wall of the indoor unit, and a flange 1 is arranged at the indoor return air outlet, the control box 2 is controlled in the outdoor unit and is located directly below the flange 1, and the flange 1 is covered with a sheath structure of any of the above embodiments to wrap the sharp edge of the flange 1, so that there is no risk of injury even if the operator touches it, thereby greatly improving production safety.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
