Main purpose of the present invention is providing a kind of improved mask, and the design that it is borrowing chute and guide rail causes capping and framework to mutually combine, and cooperates corresponding aperture that capping is limited the location with limiting section, and then reaches and be easy to the purpose assembling and dismantle.

For reaching above-mentioned purpose, improved mask of the present invention comprises: the both sides of an end face are respectively equipped with the framework of guide rail, and an end of each guide rail is respectively equipped with a limiting section, and this framework bottom surface is provided with most pins, and on this framework one end face, are provided with a perforation; One activity is combined in the capping on the framework end face, and these capping both sides are respectively equipped with the chute that docks with guide rail, and an end of each chute has the corresponding aperture that docks with limiting section respectively; And the connector that is combined in the perforation.

In one embodiment of this invention; This framework includes interconnective biside plate and two end plates; And each chute is located at the end face of biside plate respectively; This perforation is located at wherein on the end plate, and the apical margin of an end plate is provided with a stopper section therein, and an end of this capping be provided with corresponding with the stopper section against kink.

In one embodiment of this invention, it is planar that this limiting section is a continuous arc.

In one embodiment of this invention, the inner edge of this perforation is provided with guidance part and abutting part, and the outer rim of this connector is provided with groove and the fixing hole that docks with guidance part and abutting part.

In one embodiment of this invention, each guidance part is the T type, and each abutting part is a bending plate.

Therefore, this improved mask of the present invention can make capping utilize the guide rail of chute and framework to mutually combine, and cooperates corresponding aperture that capping is limited the location with limiting section, is easy to the effect assembling and dismantle and reach.

Embodiment

For fully understanding the object of the invention, characteristic and effect, existing by following concrete embodiment, and cooperate appended graphicly, the present invention is done a detailed description, explain as after:

Please with reference to (Fig. 2,3,4,5,6,7 and Fig. 8 is respectively vertical view, the A-A profile of Fig. 6 and the B-B profile of Fig. 6 of joint connector in the front view of the outside drawing of the exploded view of preferred embodiment of the present invention, preferred embodiment of the present invention, preferred embodiment of the present invention, the partial enlarged drawing of Fig. 4 A of the present invention part, the preferred embodiment of the present invention.As shown in the figure: improved mask of the present invention includes a framework 1, a capping 2 and a connector and constitutes.

The above-mentioned framework of carrying 1 includes interconnective biside plate 11 and two end plates 12; And the end face of its biside plate 11 is respectively equipped with a guide rail 13, and an end of each guide rail 13 is respectively equipped with a limiting section 131, and it is planar that this limiting section 131 is a continuous arc; And this framework 1 bottom surface is provided with most pins 14; And wherein be provided with a perforation 15 on the end face on the end plate 12 in this framework 1, and the inner edge of this perforation 15 is provided with guidance part 151 and abutting part 152, each guidance part 151 is the T type; Each abutting part 152 is a bending plate, in addition this wherein the apical margin of an end plate 12 be provided with a stopper section 16.

These capping 2 activities are combined on the end face of framework 1; And these capping 2 both sides are respectively equipped with the chute 21 that docks with guide rail 13; And an end of each chute 21 has the corresponding aperture 22 that docks with limiting section 131 respectively, and an end of this capping 2 be provided with corresponding with stopper section 16 against kink 23.

This connector 3 is combined in the perforation 15 of framework 1 one end faces, and the outer rim of this connector 3 is provided with the groove 31 and fixing hole 32 that docks with guidance part 151 and abutting part 152.

When the present invention in when assembling; This connector 3 is corresponding with the perforation 15 of framework 1, and the groove 31 of connector 3 is slidingly installed on the guidance part 151 of perforation 15, so; Can let connector 3 be located in the perforation 15 of framework 1 with predetermined angle; And the fixing hole 32 that makes connector 3 is corresponding each other with abutting part 152, and with abutting part 152 toward the direction of fixing holes 32 folding that breaks, and the assembling of completion connector 3; Afterwards again with the chute 21 respectively corresponding guide rail 13 that slip into framework 1 of capping 2 with its both sides; And when capping 2 cunnings are established to sealing framework 1, corresponding aperture 22 is docked with limiting section 131, and let kink 23 be resisted against on the stopper section 16 simultaneously; So, just, can constitute a communication mask.

And when dismounting; Toward promoting, and make corresponding aperture 22 leave limiting section 131 in the other direction capping 2, and with capping 2 with its chute 21 by shifting out on the guide rail 13; Again abutting part 152 is turned down out in the fixing hole 32 afterwards; And let connector 3 cooperate guidance part 151 to shift out perforation 15 with its groove 31, so, just can accomplish the dismounting of capping 2 and connector 3.

As stated, the present invention meets patent three important documents fully: novelty, creativeness and practicality.With creative, the present invention is borrowing the design of chute and guide rail, causes capping and framework to mutually combine with novelty, and with limiting section cooperation corresponding aperture capping is limited the location, and then reaches and be easy to the effectiveness assembling and dismantle; With regard to practicality, the product that utilizes the present invention to derive is when the demand that can fully satisfy existing market.
