Description

Technical Field

[0001] The utility model relates to the technical field of refrigerated containers, and more specifically, to a novel prefabricated hole plug for a generator of a refrigerated container. Background Art

[0002] For example, CN202320481323.1 discloses a container unit with a lifting device, including a box body, a diesel generator set, a sliding component, a lifting component, a partition, a shutter and a radiator. The lifting hole is convenient for tying the lifting rope for binding the diesel generator set to the third fixed plate. The third nut and the third screw are used to lock the first fixed plate and the second fixed plate, so that the movement of the first sliding wheel and the second sliding wheel is stable, which is convenient for the later maintenance and disassembly of the diesel generator set. The exhaust fan main body is used to dehumidify the space where the diesel generator set is located. The cooperation of the radiator and the shutter is used to cool the inside of the box.

[0003] This prior art describes the connection relationship and structural features of containers or refrigerators with components such as generators and motors with pictures and texts. Among them, traditional refrigerators are equipped with two generator nuts at the front frame. In order to prevent water from entering the front corner column, PVC plugs are used to plug the nut ends and glue them, which can avoid water ingress. However, the plugs will age after long-term use, and the surrounding sealants will also age, affecting the sealing, causing water to enter the corner column, aggravating the rust inside the corner column, and affecting the overall strength of the corner column. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a new type of prefabricated hole plug for a refrigerated container generator to solve one or more of the above-mentioned problems.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A novel prefabricated hole plug for a refrigerated container generator comprises a corner column member, wherein the corner column member is connected to the refrigerated container through a refrigeration nut, a threaded tube is passed through the corner column member, rubber plugs are inserted into both ends of the threaded tube, and a plurality of single blades are arranged on the plug column of the rubber plug.

[0007] Furthermore, the single blade is an annular member, and the end of the single blade is warped.

[0008] Furthermore, the single blades are arranged on the plug of the rubber plug at equal intervals and the number is not less than three groups.

[0009] Furthermore, the plug head of the rubber plug is provided with a sunken cavity, and a handle with a hole is provided in the cavity.

[0010] Furthermore, an O-ring is provided on the plug head of the rubber plug, and a concave rubber storage cavity is provided between the end of the plug head of the rubber plug and the O-ring.

[0011] Furthermore, the corner column element comprises

[0012] The front corner column inner part is a multi-section bent part;

[0013] The front corner column outer member is a single-section bent member;

[0014] After the front corner column inner part and the front corner column outer part are connected, a cavity is formed inside, and the threaded tube is communicated with the cavity.

[0015] Furthermore, a stainless steel wire is provided at the end of the cooling machine nut, and the other end of the stainless steel wire is connected to the outer end of the rubber plug.

[0016] In summary, the utility model has the following beneficial effects:

[0017] By setting three layers of single blades on the rubber plug, the friction with the inner wall of the threaded tube is increased, thereby achieving the purpose of improving the sealing and anti-slip performance of the rubber plug. By setting a glue storage cavity at the plug head of the rubber plug to accommodate more sealant, combined with an O-ring, the sealing of the threaded tube is further improved. The rubber plug to be removed later on the outside is connected to the cold machine nut through a stainless steel wire to prevent loss, and can be reinserted into the threaded tube after the motor is removed.

[0023] Example:

[0024] The following is combined with Figure 1-4The utility model is described in further detail.

[0025] A new type of prefabricated hole plug for refrigerated container generator, such as Figure 1 As shown, the corner column member is formed by welding the front corner column inner member 170 with multiple bends and the front corner column outer member 180 with a single bend at the ends, and a cavity is formed between them. A threaded tube 150 is passed through the corner column member, and the threaded tube 150 connects the external environment and the cavity. The corner column member is fixed to the refrigerator through a refrigerator nut 210.

[0026] Rubber plugs 190 are inserted into both ends of the threaded tube 150 , and the rubber plugs 190 play a role in blocking the connection between the threaded tube 150 and the cavity, and the threaded tube 150 and the outside world.

[0027] A stainless steel wire 200 is provided on the cold machine nut 210, and the other end of the stainless steel wire 200 is connected to the outer rubber plug 190 to prevent the rubber plug 190 from being removed later and accidentally lost when the motor is installed in the hole. This is because the removed rubber plug 190 needs to be reinstalled back into the threaded tube 150 after the motor is removed to prevent external impurities such as rainwater from entering the cavity and causing rust to the diagonal columns, the internal rubber plug 190, and other equipment.

[0028] like Figure 2 and Figure 3 As shown, the outer end of the plug head of the rubber plug 190 is provided with a sinking groove, and a handle 130 with a hole is provided in the groove. The stainless steel wire 200 is connected to the handle 130 with a hole, and the rubber plug 190 can be removed or plugged back more conveniently through the handle 130 with a hole. A fixed O-ring 140 is provided near the end of the plug head of the rubber plug 190, and the sealing performance of the rubber plug 190 is enhanced by conventional means. A concave circular cross-section groove is provided between the O-ring 140 and the end to form a glue storage cavity 110. Compared with conventional means, the design of the glue storage cavity 110 can accommodate more sealant, which innovatively improves the sealing performance of the rubber plug 190. The plug part of the rubber plug 190 is provided with three groups of single blades 120 arranged at equal intervals. The single blade 120 is an annular disk with an upward tilt at the end, which effectively prevents external liquid or foreign matter from entering the cavity when in use, and also improves the friction between the rubber plug 190 and the inner wall of the threaded tube 150, and strengthens the anti-slip and sealing. More sealant means that the aging process is prolonged, and a more scientific sealing plug design effectively reduces external corrosion to the rubber plug 190, prolongs the service life, alleviates the rust inside the corner column, and improves the overall strength of the corner column.

[0029] It should be noted that this specific embodiment is merely an explanation of the present utility model, and it is not a limitation of the present utility model. After reading this specification, those skilled in the art can make non-creative modifications to the present embodiment as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
