Description

Upspring type ground audio engineering box

Technical field

The utility model relates to the line connector of a kind of power line and electrical signal line, especially a kind of floor socket outlet embedded box that is used for the acoustic signal line.

Background technology

At present, generally the power line socket embedded box of Shi Yonging because of being embedded on the ground surface, can avoid common socket because of being exposed to the outer generation that causes contingency, and is safe in utilization, convenient.But also do not have the built-in type socket box at present in the sound technique field, thereby wiring, inlet wire cross one another easily, circuitous circuit is more, and very not attractive in appearance, easy break-down influences communication quality.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of ground audio engineering box that is embedded in, and it makes more convenient, the standard of wiring, reduces rate of breakdown, improves signal quality.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this upspring type ground audio engineering box, comprise the end box that is used to be embedded in the ground surface place, the through hole that can supply lead to penetrate is arranged around the end box, on end box, be fixed with a fixed cap, cover and have hollow part, establish one at through-hole part and play the acoustic signal line socket panel fixed mount that self-locking device is connected on by one with fixed cap, there is switching device at the edge of fixed cap, acoustic signal line socket panel is equipped with in the front of fixed mount, a cover plate that can cover the fixed head through-hole part, cover plate are equipped with in the top, panel is releasable connection with securing member and fixed mount.Described going up plays the two upper and lower fixtures that interconnect that self-locking device comprises and fixed cap is fixed, following fixture both sides have the bearing pin that is rotationally connected with fixed mount, all are with the oblique shape block that a bipod is supported on torsion spring on fixture and the fixed mount and protruding appropriate position, bottom built in fixed mount symmetry both sides respectively on the axle and constitute.Described switching device comprises that one places the pushing block in the fixed cap chute, the protruding boss that is shaped in pushing block bottom, and the through hole that boss passes chute is connected by spring-supported snap close with one, and buttonhole is arranged on the cover plate.

Compared with prior art, advantage of the present utility model is:

1, play self-locking structure flexible operation, freely on, easy to use, the acoustic circuit hierarchical link is clearly demarcated, avoids intersecting, and can reduce rate of breakdown, improves signal quality.

1, box body highly versatile is fit to the various different types of sound equipment socket panels of assembling, is convenient to the maintenance and the replacing of panel.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Figure 1-3, upspring type of the present utility model ground audio engineering box is mainly by end box 1, fixed cap 3, fixed mount 2, acoustic signal line socket panel 5, cover plate 4 and go up and play self-locking device and switching device assembles.Wherein end box 1 is embedded in the ground surface place in use, and it can do squarely, circle and other geometry.The bottom of box and sidewall all are shaped on the through hole (not shown), penetrate with socket for lead to be connected.

Fixed cap 3 is fixed on the end box 1, has a hollow part 31 on it, socket panel fixed mount 2 bullet or press down on this hollow part 31.The edge of fixed cap has chute 32, and through hole 321 is arranged in the groove, and pushing block 7 in the switching device and snap close 8 are separately fixed at the upper and lower both sides of chute 32.

When the effect of switching device is non operating state, socket panel fixed mount 2 is pinned, make fixed mount 2 be in hiding low level, make ground smooth; When working, the snap close 8 in the cancel switch device is sealed with keyhole 41, and fixed mount 2 utilizes last bullet self-locking device to finish to flick and opens.This switching device is made of spring 9, pushing block 7 and snap close 8, and the protruding boss 71 that is shaped in the bottom of pushing block 7 is shaped on internal thread hole in the boss, and boss 71 passes the chute through hole 321 of fixed cap and uses screw attachment with snap close 8.Be provided with a spring 8 between snap close rear wall and fixed cap inwall.Snap close 8 under pushing block 7 drives under the promotion of hand moves up and down along chute 32 together.

Socket panel fixed mount 2 is a frame-type member, and socket panel 5 is plugged on the fixed mount 2 and by the cover plate 4 that is fixed on the fixed mount and fixes.Each jack that is fixed on socket panel 5 its panels in the fixed mount is exposed to fixed mount front openings place.Cover plate 4 use screw attachment with fixed mount 2, and it detachably is convenient to change or keep in repair socket panel, and when fixed mount 2 presses down when being in non operating state, cover plate 4 covers the through-hole part 31 on the fixed cap.Be shaped on buttonhole 41 on the cover plate 4, with snap close 8 fastenings in the switching device.And the appropriate position, bottom of the symmetrical both sides of fixed mount is shaped on an oblique shape block 22 respectively, it with constitute going up of fixed mounts with fixing two upper and lower fixtures that interconnect 10,11 of fixed cap 3 and torsion spring 12 and play self-locking device.There is bearing pin following fixture 11 both sides, and fixed mount 2 is rotationally connected with following fixture 11, and torsion spring 12 is enclosed within on the bearing pin, and its bipod is supported on respectively on fixture and the fixed mount.This device utilizes the elastic force of torsion spring to make that bullet to the block on it contacts with fixed cap on the fixed mount, makes fixed mount be in a certain opening angle, and socket is for using; When pushing fixed mount downwards and pinning, socket is in the end box and capping is smooth with snap close.

This engineering box is to connect for the acoustic signal line to use, each jack on the socket panel is O type jack, comprise audio jack, video jacks etc., but difference according to user's use, jack setting on the socket panel can be varied, as Fig. 1, Fig. 4, shown in Figure 5 be wherein three kinds of panel styles, except above-mentioned three kinds of styles, also can select other socket panel for use, and the box body of engineering box can be general.
