Abstract
The utility model discloses a concealed electric grill fence used for windows and balconies. A motor is utilized to drive a top and a bottom guide screw rods which are provided with two sections of guide threads to rotate. Therefore, a fence on blank holder guide blocks and screw nut guide blocks and is connected with the guide screw rods can accomplish opening and closing works. The screw rods are arranged in a screw rod box in wall body, and the fence can be collected in a fence box in the wall body. The utility model has the advantage of concealed and shapely appearance. The utility model can be opned and closed random according to the requirements and is convenient for fire fighting.
Description
The utility model relates to housing window, and especially guard-rail for window is made the field.
For the needs of secure context, all be provided with protective guard on the window in a lot of dwelling houses, office building, hotel and the balcony, these protective guards are generally fixedly iron bar, during installation, cover in outside window regularly.There is many-sided shortcoming in these protective guards; The first is used inconvenience, can not open, and daylighting is poor.It two is poor stability, and when breaking out of fire was sealed up a door, the personnel in the room can't get out, and the rescue personnel advances not go.It three is to influence the city outward appearance.
The purpose of this utility model is, designs a kind of protective guard that can open and close and have stealthy effect as required arbitrarily, makes it overcome the above shortcoming of prior art.
The purpose of this utility model realizes by following means.
In the protective guard that constitutes by portable fence and travel mechanism, by motor, down screw mandrel, upper screw rod and be connected down screw mandrel and upper screw rod between transmission mechanism constitute screw mandrel rotation conveyer chain; Left side fence and right fence are connected on upper screw rod and the following screw mandrel by sky cover guide block and nut guide block, and screw mandrel all has two sections guide thread up and down; Nut guide block on the fence of a left side is a forward leading nut; Nut guide block on the right fence is anti-silk nut.
After having adopted above design, when opening protective guard, motor just changes, and two screw mandrels rotate thereupon, place sky cover guide block on the screw mandrel and nut guide block to drive about two fence slide to both sides; When closing protective guard, the motor counter-rotating, guide block drives left and right sides fence and slides to central authorities, realizes closing.Owing to screw mandrel can be located in the screw mandrel box that places in the body of wall, fence also can be folded in the fence box that places in the body of wall, so the utility model can be installed in the adjacent window body of wall stealthyly, and is both elegant in appearance, again can be as required arbitrarily folding, and when fire takes place, do not hinder and pass in and out in personnel.
Description of drawings is as follows,
Fig. 1 is the partial sectional view of the utility model example structure.
Fig. 2 is the structure chart of man-operated mechanism.
Below, in conjunction with the accompanying drawings structure of the present utility model is described in further detail.
In Fig. 1, motor 1, following screw mandrel 2, upper screw rod 3 and be connected down screw mandrel and upper screw rod between transmission mechanism constitute screw mandrel and rotate driving-chain, in this example, transmission mechanism is by travelling gear 12,13,14,15 and power transmission shaft 11 constitute two sections incorgruous screw threads about screw mandrel all has up and down.A left side fence 4 and right fence 5 are connected on upper screw rod and the following screw mandrel by sky cover guide block 6 and the nut guide block that sky is enclosed within on the screw mandrel up and down, and the installation of left and right sides fence need be overlapped guide blocks with many skies, and two nut guide blocks 7 on the left fence and 8 are forward leading nut; Two nut guide blocks 9 on the right fence and 10 be an anti-nut.Drive screw mandrel rotation down when motor rotates, and again the rotary power of drive link is passed to upper screw rod, upper screw rod is rotated by travelling gear 14,15; Be rotated with and under the influence of screw mandrel turn, drive left and right sides portable fence at four nut guide blocks on the screw mandrel and stretch to two edge contractions, thereby realized the folding of protective guard to the center.For the purpose of attractive in appearance, screw mandrel places respectively within upper screw rod box 18 and the following screw mandrel box 19 up and down, and left fence and right fence can be folded in respectively within left fence box 20 and the right fence box 21.When actual installation, screw mandrel box and fence box can place in the window frame body of wall on every side, and when protective guard was opened, the whole protection hurdle contracts folding in body of wall, and was both convenient and practical, elegant in appearance again.
The electronic mode that is based on the utility model designs, but consider in some power failure occasion, the urgent moment that the fire power supply stops especially to appear, still can open protective guard, the ad hoc hand gear of having counted, promptly at driving gear pair 12, set up one near 13 and had manual rotating shaft 16, and can slide and the free gear 17 that is meshed with gear pair 12,13 along rotor shaft direction, as shown in Figure 2, at ordinary times, gear 17 can slide and other gear disengaging engagement along rotating shaft, when needs are manual, gear 17 is slid into the position that is meshed with other travelling gear along axle, with handle transmitting gear 17, screw mandrel rotates thereby drive up and down, manually finishes the folding of left and right sides fence.Certainly, transmitting gear 17 also can be arranged between gear 12 and 13 in a fixed manner.
In some certain location, limit switch can be set as 20 places, middle part at the upper screw rod box.
Though the utility model is suitable for window and balcony protection most, also can be as the protection mechanism of door.
