A station building, the top of which is suspended and fixed with the above-mentioned detachable hook.

The utility model has the following beneficial effects:

The detachable hook of the utility model and the station house with the detachable hook, when in use, the straight screw rod is welded and fixed on the steel plate on the top of the station house (welding or screw and steel plate connection can be used), and the straight screw rod is screwed into the lower part of the straight screw rod. Screw the upper nut into the lower nut on the upper part of the hook, then screw the upper end of the extension nut into the lower end of the straight screw, then select the upper end of the hook into the lower end of the extension nut, and finally tighten the upper nut and the lower nut at both ends of the extension nut. That's it. When the utility model needs to dismantle the hook, directly loosen the lower nut and unscrew the hook from the lengthening nut. And the hook in the prior art is welded on the body of wall, if changing a new one, needs to cut off and just can change. The detachable hook of the utility model adopts a screw connection structure, which is convenient for disassembly and replacement of the hook.

detailed description

In order to make the technical problems, technical solutions and advantages to be solved by the utility model clearer, the following will describe in detail with reference to the drawings and specific embodiments.

On the one hand, the utility model provides a detachable hook, as shown in Figure 1, comprising a straight screw 1 for hanging and fixing on the top of the station building and a hook 2 arranged below the straight screw 1, the upper part of the hook 2 is provided with threads An extension nut 3 is threadedly fixed between the straight screw 1 and the hook 2, and an upper nut 4 and a lower nut 5 for locking the extension nut 3 are arranged between the straight screw 1 and the hook 2 and the extension nut 3 respectively.

When the utility model is applied, the straight screw rod 1 is welded and fixed on the steel plate on the top of the station building (welding or screw plus steel plate connection can be used), the upper nut 4 is screwed into the lower part of the straight screw rod 1, and the lower part is screwed into the upper part of the hook 2. Nut 5, then the extension nut 3 upper end is screwed into the straight screw 1 lower end, then the hook 2 upper end is selected into the extension nut 3 lower end, and finally the upper nut 4 and the lower nut 5 at both ends of the extension nut 3 are tightened and locked. When the utility model needs to disassemble the hook 2, directly unscrew the lower nut 5 and unscrew the hook 2 from the lengthening nut 3 to get final product. And the hook 2 in the prior art is welded on the body of wall, if changing a new one, needs to cut off and just can change. The detachable hook of the utility model adopts a threaded connection structure, which facilitates the disassembly and replacement of the hook 2 .

Preferably, the length of the extension nut 3 is greater than or equal to 25mm; the length of the upper nut 4 and the lower nut 5 is less than or equal to 10mm.

As an improvement of the utility model, both the upper nut 4 and the lower nut 5 can be hexagonal nuts. The application of hex nuts is the most common, not only convenient to purchase, but also convenient for tools such as wrenches to screw in and disassemble them.

In the utility model, the specifications of the straight screw rod 1, the extension nut 3, the upper nut 4 and the lower nut 5 are all M10, and the specification of the M10 is about 10 mm in diameter, about 1.5 mm in pitch, and about 8.5 mm in diameter of the bottom hole.

Preferably, the length of the upper nut 4 screwed into the straight screw 1 is 18-22 mm; the length of the lower nut 5 screwed into the hook 2 is also 18-22 mm.

In order to avoid hurting hands and remove burrs, the straight screw 1, hook 2, extended nut 3, upper nut 4 and lower nut 5 all adopt the sharp-angle blunt process.

In order to improve the service life of the detachable hook, the straight screw 1, the hook 2, the extended nut 3, the upper nut 4 and the lower nut 5 are made of stainless steel. The stainless steel material has good anti-rust performance, and saves the use of spray painting and anti-rust layer processes.

On the other hand, the utility model also provides a station building, the top of the station building is suspended and fixed with the above-mentioned detachable hook.

The foregoing is a preferred embodiment of the present utility model, and it should be pointed out that for those of ordinary skill in the art, some improvements and modifications can be made without departing from the principle of the present utility model. Retouching should also be regarded as the scope of protection of the present utility model.
