Description

The security door transaction window of exempting to open the door

1, technical field:

The utility model relates to a kind of security door, particularly with the security door of fenestella (exempt from open the door transaction window).

2, background technology

In the security door of existing band fenestella, the plug-type flat opening that also has is arranged, but all be that armrest directly drives and opens or closes fenestella.

3, technology contents

The purpose of this utility model is to overcome plug-type fenestella the deficiencies in the prior art, designs security door that a kind of fenestella can the automatic shutter transaction window of exempting to open the door.

The utility model is such realization:

A kind of security door transaction window of exempting to open the door, the fixed head that comprises the band sliding sleeve that is fixed on the body, be loaded on the transaction window that opens the door of exempting from the sliding sleeve, it is characterized in that concluding the business and be fixed with the transmission limited block on the window, on fixed head, be provided with the automatic driving locking mechanism of transmission limited block, and drive locking mechanism automatically and comprise:

Be symmetrically set in the limiting plate on fixed head both sides, be fixed in the spacing sleeve-board on the fixed head, the limiting plate middle part is articulated in limiting plate by lateral pin and puts, and between limiting plate head and spacing sleeve-board back-moving spring is housed;

A movable slip pipe is equipped with extension spring in the movable slip pipe, and the extension spring two ends are fixed with the collision block greater than the slip pipe external diameter, also is fixed with to drive the driving chip that limiting plate rotates on slip pipe;

On slip pipe, also be fixed with to drive and pitch, on fixed head, also be provided with and drive the shifting fork mechanism that fork cooperates.

Described limiting plate and associate member also can directly be loaded on the sliding sleeve and need spacing sleeve-board promptly by the limiting plate cover effect of having held concurrently of sliding sleeve plate, and slip pipe also can be located on the slideway ad hoc on the fixed head.

Further scheme is:

Described spacing sleeve-board is two, and each limiting plate puts and have groove, and limiting plate lays respectively in the groove that two limiting plates put:

Slip pipe is between two spacing sleeve-boards:

Driving chip is positioned at the below of limiting plate;

Described shifting fork mechanism can be to fix a support on the fixed head, has a knob to be loaded on the support, and the preformed hole on the fixed head is passed in the knob end, is fixed with shifting block in the knob end, shifting block with pass fixed head on the driving fork of preformed groove cooperate.

In the utility model, spacing sleeve-board can be only one, and this moment, slip pipe preferably was located between spacing sleeve-board and the sliding sleeve, and described shifting fork mechanism also can be located at the fixed head front, and does not need to establish on fixed head preformed hole and preformed groove.

The utility model has the advantages that: no matter open or close fenestella, if turning knob, thus realized the automation of fenestella switch.

5, embodiment

Below, in conjunction with the accompanying drawings the utility model is done detailed description:

As Fig. 4, Fig. 5 and Fig. 6, described slip pipe 10 two ends are fixed with л shape driving chip 13, and slip pipe 10 middle part downsides are fixed with and drive fork 21, but slip pipe 10 integral manufacturings of this band driving chip 13 and driving fork.

As Fig. 1, Fig. 2 and Fig. 3, a kind of security door transaction window of exempting to open the door, comprise the fixed head 16 that is fixed on the body, fixed head 16 tops do not have sliding sleeve 15, the movable fenestella 14 of band roller 18 is housed in the sliding sleeve 15, be fixed with transmission limited block 9 at fenestella 14 lower left quarters, be fixed with two the spacing sleeve-boards 8 parallel on the fixed head 16 below sliding sleeve 15 with sliding sleeve 15, have groove on the spacing sleeve-board 8, limiting plate 2 lays respectively in two grooves on the spacing sleeve-board 8, and limiting plate 2 middle parts are articulated on the spacing sleeve-board 8 by lateral pin 3, between limiting plate 2 heads and spacing sleeve-board 8 back-moving spring 4 are housed; Slip pipe 10 is between two spacing sleeve-boards 8 and parallel with limiting plate 8, л shape driving chip 13 on the slip pipe is arranged in the cavity below the spacing sleeve-board 8 and can horizontally slips on lateral pin 3 both sides, pass the preformed groove of driving fork 21 from fixed head 16 on the slip pipe 10, extension spring 11 is housed in the slip pipe 10, and extension spring 11 two ends are fixed with the collision block 1 greater than slip pipe 10 external diameters; Also be provided with support 6 in fixed head 16 bottoms, have a knob 20 to be loaded on the support 6, the preformed hole on the fixed head 16 is passed in the end of the rotating shaft 5 of knob 20, is fixed with shifting block 19 in the end, and shifting block 19 cooperates with driving fork 21.

Its operating principle is: when knob 20 clockwise directions rotate, driving shifting block 19 rotates synchronously, shifting block 19 promotes to drive fork 21 and moves right along the preformed groove on the fixed head 16, driving fork 21 drive sliding sleeves 10 and л shape driving chip 13 moves to right synchronously, the л shape driving chip 13 of left clockwise direction under the effect of lateral pin 3 on the upper limit plate 2 rotates on the one hand, thereby appearing of upper limit plate 2 is withdrawn in the upper limit sleeve-board 8, on the other hand, the л shape driving chip 13 on the right stretches out lower limiting board 2 from lower limit sleeve-board 8, meanwhile, the collision block 1 that is contained in slip pipe 10 left ends is appeared and the effect lower stress of transmission limited block 9 at the upper limit plate 2 of extension spring 11, in the time of in appearing of upper limit plate 2 is fully retracted to upper limit sleeve-board 8, upper limit plate 2 appear and collision block 1 between transmission limited block 9 under the effect of the inertia force of collision block 1, drive fenestella 14 and run to right-hand member rapidly, and be locked to lower limiting board 2 appear and the collision block 1 of right-hand member between, fenestella 14 promptly is opened; In the time will closing fenestella, only need knob 20 is rotated to counter-clockwise direction, appearing of lower limiting board 2 is withdrawn in the lower limit sleeve-board 8, the collision block 1 of slip pipe 10 right-hand members is in extension spring 11 simultaneously, the effect lower stress of appearing of lower limiting board 2, in the time of in appearing of lower limiting board 2 withdrawn lower limit sleeve-board 8 fully, lower limiting board 2 appear and collision block 1 between transmission limited block 9 under the effect of the inertia force of right-hand member collision block 1, drive fenestella 14 and run to left end rapidly, and be locked to upper limit plate 2 appear and the collision block 1 of left end between, wherein Suo Hui limiting plate 2 appears under back-moving spring 4 and effect, as long as л shape driving chip 13 is not positioned at back-moving spring 4 one ends of limiting plate 2, the appearing to automatically reset of limiting plate 2 exposed.Described limiting plate 2 can be regarded as a lever.

When actual fabrication, should also be noted that the matching relationship of л shape driving chip 17 and limiting plate 2, and select rational extension spring 11 and back-moving spring 4.

Fig. 7 has provided the embodiment that spacing sleeve-board 8 has only, spacing sleeve-board 8 two ends all have groove among the figure, and two limiting plates 2 and back-moving spring 4 thereof, lateral pin 3 are loaded on respectively in the groove at these spacing sleeve-board 8 two ends, its operating principle is the same during with two spacing sleeve-boards 8, just this moment, slip pipe 10 was preferably between spacing sleeve-board 8 and sliding sleeve 15, in case 10 swings of on-slip pipe.
