Example 1

The utility model provides an explosion-proof antenna device, including casing 1, connector 2 and antenna 3. The shell 1 is a barrel structure, and the barrel structure is a bucket-shaped structure with one end open and the other end closed. The material of the shell 1 is an explosion-proof material, preferably polymethyl methacrylate (PMMA) material or Polycarbonate (PC) material, and the two materials have flame retardant property and good antistatic effect, and can be well applied to explosion-proof places. The connector 2 is a cylindrical structure with two open ends, and the connector 2 is preferably made of stainless steel materials and has good explosion-proof performance. The end of the connector 2 is connected with the open end of the housing 1 in a sealing manner, preferably in a threaded manner, and a sealing gasket can be added to enhance the sealing performance. The main body of the antenna 3 is arranged in the shell 1, the part close to the end part penetrates through the hollow interior of the connector 2 and extends out of the connector 2, and the part of the antenna 3 positioned in the connector 2 is in sealed fixed connection with the connector 2 in a pouring mode. Preferably, the part of the antenna 3 located in the connector 2 is sealed with the connector 2 by pouring epoxy resin, so that the environment is protected and the energy is saved.

The utility model provides an explosion-proof antenna device, simple structure, simple to operate, the installation in explosion-proof place of specially adapted is used, effectively guarantees wireless signal's transmission.

Preferably, connector 2 is cross structure, is equipped with the internal thread, and corresponding casing 1's uncovered tip is equipped with the external screw thread, when casing 1 revolves soon with connector 2 and is connected, and cross structure can act as effectual backstop, and conveniently improves sealed effect through addding sealed the pad or scribbling sealed glue.

Furthermore, the wall thickness of the shell 1 is selected to be 3-5 mm, and particularly preferably, the wall thickness of the shell 1 is 4mm, so that the transmission effect of wireless signals is ensured.

Example 2

The embodiment 2 is formed on the basis of the embodiment 1, and is mainly suitable for more antennas of different models by optimizing the split structure of the shell, so that the application range of the device is improved, and meanwhile, the production cost can be effectively reduced. Specifically, the method comprises the following steps:

casing 1 designs for the components of a whole that can function independently structure, including end cap 11 and barrel 12, and at this moment, barrel 12 is the open body structure in both ends, and end cap 11 sealing connection forms barrel-shaped casing 1 in the one end of barrel 12. When the housing 1 is designed to be a split structure, when the antennas 3 with different lengths need to be selected due to the power, only the cylinder 12 with the corresponding length needs to be selected, so that one end cap 11 can correspond to multiple cylinders 12, and the production cost is reduced. In addition, the shell 1 with the split structure is not required to be arranged by a special die, so that the processing difficulty of the product is effectively reduced.

Preferably, to improve the sealing effect, the connection between the end cap 11 and the barrel 12 is a screw fit connection. When the end cap 11 is internally threaded, the end of the barrel 12 is provided with a matching external thread and vice versa.
