Abstract

The utility model relates to a thief-proof device for a telescopic iron-door, composed of a telescopic door driven by a power element and a rotatable rotary shaft and two pulleys of the rotary shaft. The pulleys can walk on a rail. The thief-proof device for the telescopic iron-door is characterized in that a near-closing post of the rotary shaft is provided with a gear which rotates integrally, and the gear can be sheathed with a rack of a buckling base; the buckling base is fixed to the ground between two rails of the near-closing post through a positioning element. The rack is engaged with the gear, and the upper end of the rack is provided with a shield. The buckling base is provided with a slot hole which is relatively long, and a bolt penetrates the long slot hole. The rack and the shield are connected by the long slot hole and a screw cap, and the height of the rack can be adjusted.

Description

The anti-theft opening apparatus of telescopic iron gate

The utility model relates to a kind of anti-theft opening apparatus of telescopic iron gate.

Existing telescopic iron gate utilizes interconnective X-shaped joint arm, reaches the closing motion of lifting simultaneously, interlock.The traditional retractable door of this kind, its wheel is walked on rail, becomes a little slip between wheel and the rail, therefore, when door is closed, advance the still available way of propelling of forcing of guilty party, do not rotate under the situation at motor drive shaft and pulley, make a unlatching, therefore, this telescopic iron gate only has switch motion easily, but it lacks closed anti-theft security.

The purpose of this utility model is to provide a kind of anti-theft opening apparatus of telescopic iron gate, and when retractable door was closed, it can be closed really, can not be pushed open by force, and preferable anti-theft effect is arranged.

The purpose of this utility model is achieved in that a kind of anti-theft opening apparatus of telescopic iron gate, retractable door and rotatable rotatable shaft by the dynamical element driving, two pulleys with the turning cylinder that can walk on rail are constituted, the nearly closed styletable of described turning cylinder, be provided with the gear of unitary rotation, but the tooth bar of gear cutting ferrule one fastening base; Fastening base is fixed on ground between two rails of nearly closed post by setting element, its rack and pinion engagement, and there is shield the tooth bar upper end.

Described fastening base is provided with than long slot bore, and bolt is tied tooth bar and shield the tooth bar height-adjustable mutually by long slot bore with nut.

The utility model is simple and reasonable for structure, and is easy to use, and when retractable door was closed, it can be closed really, can not be pushed open by force, and preferable anti-theft effect is arranged

Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.

Fig. 1 is an exploded perspective view of the present utility model;

Fig. 2 is the partial groups of the present utility model view that closes;

Fig. 3 is the A-A sectional drawing of Fig. 2;

Fig. 4 is the action diagram of Fig. 3.

See also shown in Figure 1ly, it is the utility model one preferred embodiment, and its retractable door 1 can be walked on rail 2, close 2 on nearly closed post 4 two rails in retractable door 1, be provided with a fastening base 3, and they can be for 15 engagements of retractable door 1 a set gear, when retractable door 1 is closed, has the effect of certain closure.

Retractable door 1 itself rotates two turning cylinders 13 by dynamical elements such as motor 11 through actuated elements such as chain 12, turning cylinder 13 2 ends are combined with pulley 14, pulley 14 can roll on rail 2, in order to drive 2 walkings of 1 pair of rail of retractable door, this practicality is newly moulded and mainly be provided with a gear 15 on one turning cylinder 13, and turning cylinder 13 is with preferable from nearly closed post 4, gear 15 is fixed on the turning cylinder 13, can become to reach rotation in the lump with turning cylinder 31, when retractable door 1 closure, gear 15 can be engaged on fastening base 3.

Fastening base 3 is located at 2 ground of two rails of nearly closed post 4, and fastening base 3 is fixed on ground by setting element 31, and its include a tooth bar 32 and on shield 33, tooth bar 32 can be mutually meshing for the tooth bar 15 that is located in the rotating shaft 13.Prevention, can prevent gear 15 by on be lifted away from tooth punching bar 32, be to adjust the height of tooth bar 32, the shield 33 of tooth bar 32 and one is provided with hole 34, hole 34 can be passed through for bolt 35, and is screwed by nut 36, and the embedding clamping is fixed, and establish long slot bore 37 by fastening base 3, pass adjustable height so that bolt 35 to be provided.

As Fig. 2, shown in 3, the utility model retractable door 2 can be walked on rail 1, and 4 formation of retractable door 1 and closed post separate or be approaching, finishes the on-off action of door, and is provided with fastening base 3 in 2 ground of two rails of nearly closed post 4.

As shown in Figure 4, when retractable door 1 when closed post 4 is closed, retractable door 1 set gear 15 is engaged on the tooth bar 32 of fastening base 3, gear 15 upper ends and shield 33 form almost approaching no gap, gear 15 can not move up and leave tooth bar 32.

When 1 one-tenth of retractable door is closed, gear 15 and tooth bar 32 engagements, so, retractable door 1 is not rotated under the situation at turning cylinder 13, and gear 15 is non-rotatable, and the desire of turning cylinder 13 is rotated, unless rotation from dynamical elements such as motor 11, therefore, retractable door 1 can't be promoted, thereby retractable door 1 has safer anti-theft effect.

Claims

1, a kind of anti-theft opening apparatus of telescopic iron gate, retractable door and rotatable rotatable shaft by the dynamical element driving, two pulleys with the turning cylinder that can walk on rail are constituted, it is characterized in that: the nearly closed styletable of described turning cylinder, be provided with the gear of unitary rotation, but the tooth bar of gear cutting ferrule one fastening base; Fastening base is fixed on ground between two rails of nearly closed post by setting element, its rack and pinion engagement, and there is shield the tooth bar upper end.

2, according to the anti-theft opening apparatus of the described telescopic iron gate of claim 1, it is characterized in that: described fastening base is provided with than long slot bore, and bolt is tied tooth bar and shield the tooth bar height-adjustable mutually by long slot bore with nut.
