Abstract

The utility model relates to a sealing water proof device for fire control and safety detection alarm products. Ordinarily, a base of a casing of an alarm is provided with a lead window and a screw hole. Water and dust can easily enter the interior of the product from the lead window and the screw hole and the reliability and the service life of the product are affected. The utility model is characterized in that flexiplast or rubber is covered on the lead window and the screw hole of a bottom casing by adopting methods of secondary injection molding, adhesion, etc. In addition, a plurality of lead holes and thread holes are prearranged in corresponding positions. After lead connection and installation are implemented for the product, the lead holes and the screw hole are both in closed states. Effects of seal and water prevention can be achieved.

Description

Fire-fighting, safety detection warning product sealing device

Affiliated technical field

The utility model relates to the sealed waterproof device of a kind of sealed waterproof device, particularly fire-fighting, security product such as detector, alarm, newspaper button modules and other products.

Background technology

Present various fire-fighting, the common structure of security alarm product are that devices such as wiring board and electronic component are installed in the plastic casing, have lead-in wire window and screw hole on the base of shell, and the lead-in wire of product all is the lead-in wire window access from base.This syndeton very easily makes water and dust enter product inside along lead-in wire window and screw hole.Thereby influence reliability of products and useful life.

Summary of the invention

The utility model provides the sealing device of a kind of fire-fighting, security alarm product, makes go between after installation window and screw hole of product be sealing state, and water can't enter along fairlead.

The scheme that its technical problem that solves the utility model adopts is: cover waterproof materials such as one deck flexiplast or rubber by methods such as quadric injection moulds at product stem lead the window's position, open some fairleads and screw hole on it as required.The aperture of fairlead is equal to or slightly less than diameter wire, after lead-in wire passes, fairlead can be sealed.This waterproof material promptly constitutes sealed waterproof device.

The beneficial effects of the utility model are, product is installed back lead-in wire window and is sealing state, and water and dust can't enter product inside, have improved reliability of products and useful life.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the drain pan external view that comprises sealing device;

Fig. 2 is the side cutaway view of Fig. 1;

Fig. 3 is the inner side view of Fig. 1;

Fig. 4 is the drain pan external view of another embodiment;

Fig. 5 is the side cutaway view of Fig. 4.

1. product drain pans among the figure; 2. sealing device; 3. fairlead; 4. screw hole.

In Fig. 1 to Fig. 3, sealing device (2) is to adopt the quadric injection mould mode that flexiplast is covered (Fig. 2 has shown the connecting structure of sealing device (2) with window) on lead-in wire window and the screw hole.Several fairleads (3) and two screw holes (4) are arranged on sealing device (2).

In Fig. 4 to Fig. 5, sealing device (2) is covered in the outside of entire product drain pan (1), presets several fairleads (2) at lead-in wire the window's position, and also correspondence presets screw hole in the screw hole position of drain pan (1).

Sealing device (2) also can be taked the bonding mode of glue with being connected of housing in above-mentioned two embodiment, and its material also can adopt other flexible waterproof materials such as rubber.Fairlead (3) and screw hole (4) can adopt non-through structure, but reserve a thin confining bed, pierce through during use to be installed again.Can guarantee that like this fairlead (3) and the screw hole (4) that have more are the sealing shape, can guarantee that again fairlead (3) and screw hole (4) adapt to the lead-in wire and the screw of different-diameter.

Claims

1. the sealed waterproof device of a fire-fighting, security alarm product, it is characterized in that sealing device (2) covers on the lead-in wire window and screw hole of warning product casing base (1) in the form of sheets, on lead-in wire the window's position, preset some fairleads (3), preset corresponding screw hole (4) corresponding to the position of drain pan screw hole.

2. a sealed waterproof device as claimed in claim 1 is characterized in that its covering position only reaches lead-in wire window and the screw hole position in the product casing base.

3. one kind as right 1 described sealed waterproof device, it is characterized in that it covers position and in the whole outer surface of product casing base.

4. one kind as claim 2 or 3 described sealed waterproof devices, it is characterized in that fairlead (3) and screw hole (4) are the non-structures that runs through, and leave skim and make it be closed state.
