Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic compatibility testing, in particular to an air waveguide for shielding compressed air on a steel plate. Background Art

[0002] During motor testing, heat is generated when the motor operates at high speed, requiring an air source to cool the product. Furthermore, lifting antenna towers are often used in electromagnetic compatibility chambers. These auxiliary equipment require an air source to function properly, so compressed air adapters are often installed on the shielding steel plates to supply air to the chamber.

[0003] Currently, a gas pipe adapter is installed on both sides of the shielding steel plate to realize the internal and external gas transfer. This type of adapter is short and easy to damage. When it is damaged, it is necessary to replace it with a new one. The damaged adapter needs to be removed as a whole and then a new one needs to be installed. This process will affect the shielding effect. Utility Model Content

This adapter is short in length and easy to damage. When it is damaged, it is necessary to replace it with a new adapter. The damaged adapter needs to be removed as a whole and then a new adapter needs to be installed. This process will affect the shielding effect.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an air waveguide for shielding compressed air on a steel plate, comprising a straight pipe, a nut and a docking joint, the inner wall of the nut being threadedly connected to the top surface of the straight pipe, the docking joint being located at both ends of the straight pipe, and the docking joint being used for connecting to external compressed gas.

[0006] As a preferred embodiment of the present invention, both ends of the straight-through pipe are provided with thread grooves, and the straight-through pipe is threadedly connected to the docking joint via the thread grooves.

[0007] As a preferred embodiment of the present invention, a vent hole is provided inside the straight-through pipe.

[0008] As a preferred embodiment of the present invention, the straight pipe, nut and docking joint are all made of metal.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0010] 1. The utility model provides a nut and a straight-through pipe. When the straight-through pipe needs to be installed on the shielding steel plate, the top end of the straight-through pipe is first inserted into the installation position on the shielding steel plate, and then the nut is used to connect with the top thread of the straight-through pipe surface, so that the straight-through pipe can be quickly installed. This solves the current choice of installing a gas pipe adapter on both sides of the shielding steel plate to achieve internal and external gas transfer. This connector is short and easy to damage. When a new connector is replaced after damage, it is necessary to remove the damaged connector as a whole and then install a new connector. This process will affect the shielding effect. The utility model achieves the effect of convenient replacement.

[0011] 2. The present invention provides thread grooves, which are used to conveniently connect the butt joint to the two ends of the straight-through pipe through thread grooves at both ends, thereby improving the docking efficiency.

[0018] 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.

[0019] like Figures 1 to 3 As shown, the utility model provides an air waveguide for shielding compressed air on a steel plate, comprising a straight pipe 1, a nut 2 and a docking joint 3. The inner wall of the nut 2 is threadedly connected to the top surface of the straight pipe 1. The docking joint 3 is located at both ends of the straight pipe 1 and is used for connecting external compressed gas.

[0023] As a technical optimization solution of the present invention, by setting up ventilation holes and utilizing the ventilation holes opened on the straight-through pipe 1, the narrow ventilation holes can ensure that the straight-through pipe 1 does not affect the shielding effectiveness of the shielding steel plate during use.

[0024] refer to Figure 1 The straight pipe 1, the nut 2 and the butt joint 3 are all made of metal.

[0025] As a technical optimization solution of the present invention, by setting the straight-through pipe 1, nut 2 and docking joint 3 to be made of metal, the straight-through pipe 1, nut 2 and docking joint 3 are all made of metal, so that the whole is not easily damaged, thereby improving the overall service life and avoiding frequent replacement of new parts in the later stage.

[0026] The working principle and usage process of the present invention are as follows: when the straight-through pipe 1 needs to be installed on the shielding steel plate, first insert the top end of the straight-through pipe 1 into the installation position on the shielding steel plate, and then use the nut 2 to connect with the top thread of the surface of the straight-through pipe 1, so as to quickly install the straight-through pipe 1, and then use the thread grooves opened at both ends of the straight-through pipe 1 to conveniently thread the docking joint 3 with the two ends of the straight-through pipe 1, thereby improving the docking efficiency, and then use the vent hole opened on the straight-through pipe 1. The narrow vent hole can ensure that the straight-through pipe 1 does not affect the shielding effectiveness of the shielding steel plate during use, and then use the straight-through pipe 1, the nut 2 and the docking joint 3 are all made of metal, so that the whole is not easy to be damaged, thereby improving the overall service life and avoiding frequent replacement of new parts in the later stage.

[0027] To sum up: the air waveguide for compressed air on the shielding steel plate is provided with a nut 2 and a straight-through pipe 1. When the straight-through pipe 1 needs to be installed on the shielding steel plate, the top end of the straight-through pipe 1 is first inserted into the installation position on the shielding steel plate, and then the nut 2 is used to connect with the top thread of the surface of the straight-through pipe 1, so as to quickly install the straight-through pipe 1, which solves the current choice of installing an air pipe adapter on both sides of the shielding steel plate to realize the internal and external gas transfer. This joint is short in length and easy to damage. When replacing a new joint after damage, it is necessary to remove the damaged joint as a whole and then install a new joint. The shielding effect will be affected in this process.
