Description

A flameproof stainless steel junction box

technical field

The utility model relates to a junction box, in particular to a flameproof stainless steel junction box.

Background technique

The junction box is a protective device for wires and cables. It can concentrate the wire connectors and facilitate maintenance. It is one of the indispensable configurations in electrical installation. However, in harsh environments such as explosive gas, corrosion, high humidity, and dust, ordinary junction boxes are incompetent, and accidents such as explosions are likely to occur, endangering people's lives and property. At this time, it is necessary to use a highly safe and more reliable flameproof junction box. The flameproof junction boxes currently used in the market generally have the following problems:

1. The signal input end is set at the bottom of the junction box, and the signal output end is set on the side wall of the junction box, so that the interior of the junction box is divided into two parts: the inlet cavity and the outlet cavity, which makes the junction box too large and difficult to process big;

2. The tightening mechanism of the box cover of the junction box is a hexagonal concave or convex. This setting has a small torque and is laborious;

3. The locking mechanism of the box cover is to set a protruding edge on the box cover, and use a screw to screw vertically downwards into the protruding structure matching the protruding edge on the junction box. Such a structure is in the structure of the junction box The additional raised edge adds to the volume of the overall box.

Utility model content

The purpose of the invention of the utility model is to provide a new flameproof stainless steel junction box to solve the above-mentioned problems in the prior art.

The purpose of this utility model can be achieved through the following technical solutions:

A flameproof stainless steel junction box, comprising a junction box body, a box cover, an input pipe, an output pipe, a sealing plug and a sealing ring; the box cover is screwed to the box body, and a sealing ring is provided between the box cover and the box body, The output cable is led out from the output tube and sealed with a sealing plug; the signal input tube and the signal output tube are arranged on the side of the box body, and the box body is an integral cavity; a signal input tube or signal output tube is provided near the box cover. The boss is provided with a locking screw perpendicular to the outer side wall of the box cover on the boss. The cover is locked from the side by the locking screw through the boss on the junction box, which is not only beautiful but also provides a large locking force.

The included angle between the input pipe and the output pipe is a right angle.

The output pipe is a threading bolt.

A ring of flanges with grooves is arranged around the top of the box cover. In order to use a variety of instruments and tools to open and close the box cover, the torque is large and labor-saving.

A safety connection line is provided between the box cover and the box body to prevent the box cover from falling off during the high-altitude installation process, causing safety accidents.

The shell is made of 304 stainless steel.

The junction box designed through the technical scheme of the utility model reasonably arranges the positions of the input and output pipes, so that the inner cavity of the junction box is integrated, which greatly reduces the volume of the junction box; in addition, the utility model locks the box cover laterally Tight, and the position of the input and output tubes is utilized, which not only plays the role of locking the box cover, but also does not increase the volume of the junction box. The utility model has the advantages of simple structure, safety and reliability, and convenient installation, and can be widely used in production.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment further set forth the structural feature of the present utility model.

A flameproof stainless steel junction box as shown in Figure 1 and Figure 2, including a junction box body 1, a box cover 2, an input pipe 3, an output pipe 4, a sealing ring 5 and a sealing plug 6; the box cover 2 and the box The body 1 is screwed, a sealing ring 5 is provided between the box cover 2 and the box body 1, the output cable is led out from the output pipe 4, and sealed with a sealing plug 6; the input pipe 3 and the output pipe 4 are arranged on the side of the box body , The box body 1 is an integral cavity; a boss 7 is provided near the lid 2 on the input pipe 3 or the output pipe 4, and a locking screw 8 perpendicular to the outer wall of the lid 2 is arranged on the boss 7.

When in use, the input pipe 3 leads the wiring of the temperature sensor into the box body 1, and the output pipe 4 leads out the output cable, and a sealing plug 6 is set in the output pipe 4 to tightly cover the output cable to play a sealing role. After the wire is connected in the box body 1, the box cover 2 is tightened; and the locking screw 8 is tightened with a tool to make the box cover 2 tightly closed and safe.

When screwing or opening the lid 2, tools can be used to utilize the groove of the flange 9 on the lid 2 to easily reach.

The explosion-proof junction box of the utility model has the characteristics of explosion-proof, anti-corrosion, dust-proof, moisture-proof and high-temperature resistance, and can be used in dangerous places with explosive gas such as chemical plants. It has a good protection effect on the temperature instrument terminal.
