Description

Technical Field

[0001] The utility model relates to the technical field of tank filling vehicles, in particular to a large-flow self-cleaning male connector for tank filling vehicles. Background Art

[0002] A tanker truck connector generally refers to the connector system used on tanker trucks. A tanker truck is a specialized vehicle used to transport and distribute liquid fertilizers or pesticides, and a tanker truck connector is a device used to connect and disconnect the tanker truck to the irrigation system.

[0003] The existing similar tank filling car connector consists of a main body, an internal plug, a spring, a retaining ring and a connecting flange. The liquid passage of the existing similar tank filling car connector is too small to meet the needs of large-flow filling; and it does not have a password anti-mistakable function, which may cause major safety accidents or losses during use. Utility Model Content

[0004] The purpose of the utility model is to provide a large-flow self-cleaning male connector for a tank filling vehicle, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A large flow self-cleaning male connector for a tank filling vehicle, comprising

[0007] A fixed base, wherein a tail cover is provided inside the bottom end of the fixed base, and a transfer core is provided inside the upper end of the fixed base;

[0008] A male head body is provided at the upper end of the adapter core, a plug is sleeved inside the male head body, and a steel cap is provided outside the fixed base and the male head body.

[0009] Preferably, the steel cap is threadedly connected to the fixed base, and the lower end of the fixed base near the steel cap is externally threadedly connected to a stop ring;

[0010] Preferably, a bar-shaped password slot is vertically provided on the outer side of the steel cap;

[0011] Preferably, the upper end of the plug protrudes from the upper end plane of the male plug body.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This is a large-flow self-cleaning male connector for tank filling vehicles. The steel cap of this product is provided with a bar-shaped password slot. When used with the corresponding password column on the female head, it can prevent the problem of mixed installation between different connectors. If the password slots of the male and female heads do not match, they cannot be connected, which improves the safety of use. In addition, the liquid hole of this connector is larger than that of other connectors, making filling faster and more efficient, saving time and cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 This is a schematic diagram of the overall explosion structure of the utility model;

[0015] Figure 2 It is a schematic diagram of the overall cross-sectional structure of the present utility model.

[0016] In the figure: 1. Fixed base; 2. Tail cover; 3. Adapter core; 4. Male connector body; 5. Plug; 6. Steel cap; 7. Retaining ring. DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figure 1-2 As shown, the utility model provides a technical solution:

[0019] A high-flow self-cleaning male connector for tank filling trucks includes a fixed base 1, a tail cap 2 disposed internally at the bottom end of the fixed base 1, an adapter core 3 disposed internally at the upper end of the fixed base 1; a male connector body 4 disposed at the upper end of the adapter core 3, a plug 5 sleeved internally on the male connector body 4, a steel cap 6 disposed externally of the fixed base 1 and the male connector body 4; the steel cap 6 is threadedly connected to the fixed base 1, and a retaining ring 7 is threadedly connected externally to the lower end of the fixed base 1 near the steel cap 6; a bar-shaped password slot is vertically disposed on the outer side of the steel cap 6; the upper end of the plug 5 protrudes from the upper end plane of the male connector body 4;

[0020] In this embodiment, a bar-shaped password slot is provided on the steel cap 6 of this product. When used in conjunction with the corresponding password column on the female head, the problem of mixed installation between different connectors can be eliminated. If the password slots of the male and female heads do not match, they cannot be docked, which improves the safety of use. In addition, the liquid hole of this connector is larger than that of other connectors, making filling faster and more efficient, saving time and cost.

[0021] When the cap 5 is in the closed position, the threaded portion 3 is screwed onto the flange 4, and the threaded portion 3 is screwed onto the flange 4. When the cap 5 is in the closed position, the threaded portion 3 is screwed onto the flange 4, and the threaded portion 3 is screwed onto the flange 4.

[0022] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
