Description

Technical Field

[0001] This utility model relates to the technical field of grain cooling units, and in particular to an anti-drag structure and a cooling unit. Background Technology

[0002] Food security is a crucial foundation of national security, and scientific grain storage is a key link in ensuring food security. Grains (such as rice, wheat, and corn) are highly susceptible to the effects of ambient temperature and humidity during storage. Grain cooling units are mobile devices specially designed based on a comprehensive analysis of the characteristics of my country's grain storage environment and climate. They are an important guarantee for grain storage facilities to achieve the goals of green grain storage and scientific grain preservation. The biggest advantage of this equipment is its ability to handle hot grain in emergencies without requiring the fixed investment of multiple devices.

[0003] After the grain cooling unit finishes cooling the grain, it is usually moved to the equipment room and left idle. The existing cable connecting the unit and the power control cabinet is connected by a plug. If the dragging action is large during the movement of the unit, there is a risk that the cable will loosen, which may burn the plug or the cable head, causing the unit to malfunction. Therefore, there is an urgent need for an anti-drag structure to ensure the stability of the cable plug. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an anti-drag structure and cooling unit, which solves the problem that if the dragging action is large during the movement of the unit, there is a risk of the cable becoming loose, which may easily burn the plug or cable head.

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0025] This utility model embodiment proposes an anti-drag structure, applied at the connection between the socket 6 and the cable 7, including:

[0026] The retaining ring 1 has a channel 102 for installing the cable 7;

[0027] The support component, located at the bottom of the socket 6 and connected to the retaining ring 1, is used to support the retaining ring 1 and to make the channel 102 coaxial with the socket 6.

[0028] In the embodiments of this utility model, such as Figure 1 As shown, the supporting component is installed in the housing of the cooling unit and located at the bottom of the socket 6. The fixing ring 1 is fixedly installed on the supporting component. The fixing method can be welding, gluing, or screw connection to ensure the stability of the fixing ring 1 on the supporting component. The supporting component can be a screw, which serves as the connection medium between the fixing ring 1 and the cooling unit to fix and assemble it. The fixing ring 1 has a circular ring structure, with its inner structure close to the outer structure of the cable 7. The cable 7 is installed in the channel 102 of the fixing ring 1 and connected to the supporting component through the fixing ring 1. This can limit the range of motion of the cable 7, avoiding overheating, burning, or even short circuit of the cable 7 head due to loosening of the plug caused by excessive pulling. This improves the electrical safety during equipment use, while reducing abnormal wear and mechanical stress between the cable 7 plug and the socket 6, which helps to extend the service life of the cable 7, plug, and socket 6, and reduce maintenance frequency and cost.

[0029] Based on the above solution, in order to facilitate the connection between the fixed ring 1 and the cooling unit housing, such as Figure 2 As shown, the load-bearing component includes a connecting plate 5. The end of the connecting plate 5 is bent downward to form a support surface 505 and a mounting surface 503. A fixing ring 1 is fixedly disposed on the support surface 505. Both the support surface 505 and the mounting surface 503 are plate structures. The support surface 505 is used for the installation of the fixing ring 1, and the mounting surface 503 is used for connection with the cooling unit housing. The fixing method for fixing the fixing ring 1 to the support surface 505 can be screw fixing. When the cable 7 is subjected to tension, the force is transmitted to the support surface 505 through the fixing ring 1, and then distributed to the housing by the mounting surface 503, avoiding stress concentration and preventing structural damage.

[0030] Based on the above scheme, in order to facilitate the assembly of the fixing ring 1 and the support surface 505, as follows: Figure 2 As shown, the supporting component also includes a base 3, which is fixedly connected to the fixing ring 1 and disposed on the support surface 505. Since the structure of the fixing ring 1 is circular, the base 3 is fixedly installed to the outside of the fixing ring 1 by means of adhesive, screw or welding, so that the length direction of the base 3 is tangent to the outside of the fixing ring 1. The base 3 is connected to the support surface 505, which increases the contact area between the fixing ring 1 and the support surface 505, thereby increasing the connection strength.

[0031] Meanwhile, to facilitate assembly, the support surface 505 is provided with a connecting hole 501, and the base 3 is provided with a mounting hole 301. The mounting hole 301 and the connecting hole 501 are positioned correspondingly. By providing corresponding connecting holes 501 and mounting holes 301 on the support surface 505 and the base 3 respectively, the fixing ring 1 can be firmly fixed to the base 3 using fasteners such as bolts and screws, which facilitates the initial assembly and the subsequent disassembly and maintenance.

[0032] Specifically, such as Figure 2 As shown, the mounting surface 503 has an oblong hole 504. The oblong hole 504 allows the connecting plate 5 to be adjusted vertically within a certain range, so that the position of the fixing ring 1 relative to the socket 6 can be finely adjusted. After adjustment, it can be directly connected to the cooling unit housing by screws or other fasteners.

[0033] Secondly, the bottom of the support surface 505 is provided with a support rib 502, which is connected to the mounting surface 503. The support rib 502 increases the connection rigidity between the support surface 505 and the mounting surface 503 and the stability of the overall structure, and can effectively resist deformation or damage caused by cable pulling or other external forces.

[0034] Specifically, such as Figure 2 As shown, the retaining ring 1 is made of elastic material and has an opening 101. Because the retaining ring 1 is elastic and has an opening 101, the cable 7 can be more easily inserted or removed without a complex assembly process. Simultaneously, two retaining plates 2 connected to the retaining ring 1 are provided on both sides of the opening 101. Each retaining plate 2 has a retaining hole 201, which is positioned correspondingly. The two plates are fixed together using bolts or similar fasteners passing through the retaining holes 201, ensuring that the retaining ring 1 is firmly closed around the cable 7, providing additional clamping force and preventing accidental cable slippage. Furthermore, the inner side of the retaining ring 1 has several protrusions 4 arranged circumferentially along the axis of the retaining ring 1. These protrusions 4 increase the friction between the retaining ring 1 and the outer wall of the cable 7, effectively preventing the cable 7 from sliding or displacing when subjected to pulling or vibration.

[0035] This embodiment also provides a cooling unit, including the aforementioned anti-drag structure. The specific structure of the anti-drag structure is as described in the above embodiment. Since this cooling unit adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
