Abstract

The utility model discloses an end movable electric telescopic door which comprises a telescopic door body with a machine head, and a door chamber composed of wall bodies on both sides of the door body, wherein the end of the door body is fixedly provided with a blocking rod, both ends of the blocking rod are extended out of both sides of the door body, and the wall bodies on both sides in an outlet of the door chamber are provided with blocking rod position-limit mechanisms. When the door is closed, the end of the door body moves to the outlet of the door chamber, and the blocking rod is blocked by the position-limit mechanism to make the end not move out. When the door is opened, the door body is pushed by the machine head to shrink and move to the door chamber, the end of the door body is movable, the position-limit mechanism limits unidirectionally, so the door body can always be pushed to the inner end of the door chamber. The requirement of the using length is satisfied by the utility model, the production length of the door body is saved and the production cost is reduced. The position-limit mechanisms can be fixed to baffle plates on the wall bodies, and U-shaped positioning rods, one end of each of which is closed, can be used for playing the theft proof and wind proof roles.

Description

Tail end is electric extendable door movably

One, technical field

The utility model relates to a kind of door, and particularly a kind of tail end is electric extendable door movably.

Two, background technology

Electric extendable door is a kind of enterprises and institutions, residential quarters, the facility that the public place is common, it generally comprises door body, door pillar and the door storehouse of electronic nose towing, and door body wherein is made up of the framework that can stretch, and the door body is compressed together in the back of opening the door, occupied certain space, be generally about 25% of gate width, attractive in appearance with maintenance for not road occupying road, the contraction Men Tizang after needing to open the door crosses the threshold in the storehouse.The tail end of existing electric expansion every body is fixed, move the storehouse of going out to prevent that tail end is also followed at closing time, so the physical length of door body is to add length computation after body shrinks with gate width (promptly using length), adopt the length of the door body of this structure to Duo about 25% than the length of actual needs, cause cost of production to improve, customer charge increases, and the social resources waste is serious.

Three, summary of the invention

1, goal of the invention: the purpose of this utility model provides and a kind ofly can reduce door under the actual situation of using the length needs and make length to reach the tail end electric extendable door movably of saving material and expense purpose satisfying.

2, technical scheme: tail end described in the utility model is electric extendable door movably, comprise scalable door body that has head and the Men Ku that forms by the body of wall of door body both sides, it is characterized in that: be fixed with lever at door body tail end, a body both sides is stretched out at the two ends of lever, and the both sides body of wall in the outlet of door storehouse is provided with the position-limit mechanism of lever.

The principle of described electric extendable door is: at closing time, electronic head pulling door body head end moves and makes a body expansion to opposite door pillar direction, simultaneously, because a door body tail end is movable, it moves with the door body, when it moves to the outlet of storehouse, the lever of door body tail end is blocked by the both sides position-limit mechanism, thereby tail end can't be moved outside the door storehouse again, but the door body continue expansion under the pulling of head, close fully until door.When opening the door, the door body shrink to move to Men Kunei under the promotion of head, and a door body tail end is movable, and position-limit mechanism is unidirectional spacing, so a door body tail end is pushed to the inner end of Men Ku always.

Described position-limit mechanism is the baffle plate that is fixed on the body of wall.

In baffle plate upper end the transverse slat that moves on the restriction lever is set, can prevents from that the body from upwards being mentioned to remove, play windproof, antitheft effect.

Described position-limit mechanism can also be a U type backstay, and the base of U type backstay is fixed on the body of wall in a storehouse, and its two sides are in the upper/lower terminal of lever respectively, and an end that is positioned at a storehouse outlet side on U type backstay is provided with the baffle plate that stops pin.The advantage that adopts the U-shaped backstay is to utilize the base of U-shaped fixing on body of wall, and the area that backstay is contacted with body of wall is bigger like this, and the intensity of connection is just higher relatively; And the side that is positioned at two U types of lever upper/lower terminal can prevent a body up and down both direction move, play antitheft, windproof effect, thereby accomplish to kill two birds with one stone.

On the contact surface of the two ends of lever or baffle plate, be provided with cushion pad, can slow down the impact of lever, improve the application life of lever and baffle plate baffle plate.

3, beneficial effect:

Tail end described in the utility model movably electric extendable door owing to adopted simple position-limit mechanism, and a lever is set at the door body tail end of activity, but saved about 25% door body expense under the requirement of using length having satisfied, by 1000 yuan of/meter calculating of market average price of door body at present, this electric extendable door approximately can be saved 2000-3000 unit, and the parts expense that increases only has dozens of yuan, significantly saved cost of production, reduced client's buying expenses, this electric extendable door is simple in structure simultaneously, manufacture also very conveniently, and can be used for the design development of existing electric extendable door.

Five, the specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3 be first kind of embodiment of the utility model, it comprises scalable door body 1, door storehouse 2, lever 3, baffle plate 4 and transverse slat 5, door body 1 is made up of the framework that can stretch, lever 3 of middle part crosswise fixed at door body 1 last framework of tail end, the both sides of a body 1 are stretched out at the two ends of lever 3, locate at closing time being used for; Be provided with the baffle plate 4 that stops lever 3 on the both sides body of wall in 2 outlets of door storehouse, baffle plate 4 upper ends are provided with the transverse slat 5 that the limiting door body is lifted.

As Fig. 4, shown in Figure 5 be second embodiment of the utility model, its position-limit mechanism is two U type backstays, can make by channel-section steel, the base of U type backstay is fixed on corresponding position on the body of wall in a storehouse 2 by trip bolt, and the top of base and lever 3 separates certain distance, can not run into when moving with an assurance door body; Two other opposed side edges is located at the upper/lower terminal of lever 3 respectively, and and lever 3 between have certain clearance, both can not contact when both having guaranteed normal use, prevent again a body up and down the accident of both direction move, played windproof, antitheft effect; An end that is positioned at a storehouse outlet side on U type backstay is provided with baffle plate 7, and its effect is to block lever 3 to limit it and move outside door storehouse 2 with unidirectional.Also be provided with cushion pad 8 at lever 3 two ends and baffle plate 7 contact portions, can slow down the impact of 3 pairs of baffle plates 7 of lever, improve the application life of lever 3 and baffle plate 7.
