Abstract
The invention provides a mine anti-explosion lead-in device and relates to wire passing lead-in devices. The mine anti-explosion lead-in device aims to solve the problem that wire passing products for two cavities of existing small-capacity mine explosion suppression and intrinsic safety type anti-explosion electric products are high in cost. The mine anti-explosion lead-in device comprises a threading screw rod, a threading fixing frame and resin, wherein the threading fixing frame is arranged in an inner cavity of the threading screw rod, the ends of lead-in wires enter the inner cavity of the threading screw rod through one end of the threading screw rod, the ends of connecting wires enter the inner cavity of the threading screw rod through the other end of the threading screw rod, the ends of the lead-in wires and the ends of the connecting wires make contact in the middle of the inner cavity of the threading screw rod and are connected fixedly, the lead-in wires and the connecting wires are respectively fixed in the inner cavity of the threading screw rod through the threading fixing frame, and the inner cavity of the threading screw rod is filled with the resin. The mine anti-explosion lead-in device is suitable for wire passing.
Description
Technical field
The present invention relates to the introducing device of line.
Background technology
Explosive gas atmosphere mine explosion-suppression and intrinsic safety type explosion-proof electric apparatus product at present, the line mode of crossing between explosion-proof chamber and intrinsic safety chamber, the introducing device of employing is horn mouth formula mounting structure and terminal-type mounting structure.
When being all enough large in mine explosion-suppression and intrinsic safety type explosion-proof electric apparatus interiors of products space, above two kinds of introducing device structures could use, for the little mine explosion-suppression and intrinsic safety type product of volume, because inner space is little, cannot use the line introducing device excessively of bulky horn mouth formula structure and terminal-type structure, Flameproof and intrinsically safe explosion precaution to introducing device, makes the cost of product high separately.
Summary of the invention
There is the problem that cost is high in the line products of crossing the object of the invention is in order to solve existing little volume mine explosion-suppression and intrinsic safety type explosion-proof electric apparatus product two cavitys, a kind of mine anti-explosion introducing device is provided.
A kind of mine anti-explosion introducing device, it comprises threading screw rod, threading fixed mount and resin, threading fixed mount is placed in the inner chamber body of threading screw rod, the end of lead-in enters by one end of threading screw rod in the inner chamber body of threading screw rod, the end of connecting line enters by the other end of threading screw rod in the inner chamber body of threading screw rod, the end of lead-in contacts and is fixedly connected with at the middle part of the inner chamber body of threading screw rod with the end of connecting line, lead-in and connecting line are fixed in the inner chamber body of threading screw rod by threading fixed mount respectively, and resin fills up the inner chamber body of threading screw rod.
The present invention, by threading screw rod cavity internal wiring, has realized the line of crossing of little volume mine explosion-suppression and intrinsic safety type explosion-proof electric apparatus product two cavitys and has installed; Lead-in contacts and is connected in threading screw rod cavity with connecting line, after line in threading screw rod cavity perfusion resin, realized the introducing of line, solved the pin problem of the mine explosion-suppression and intrinsic safety product of small size, reduced because introducing device affects the production cost increasing, also widened mining product in the lower range of application of Minepit environment simultaneously.
