Abstract
The utility model provides a telescopic gate which comprises a base station and a telescopic door which is connected with the base station, wherein the telescopic door comprises a plurality of gate units and a driving frame which is connected in series with the gate units into a whole and drives gate units to expand and contract, and the telescopic door uses building materials with a cross section of arc-shaped structure. The telescopic gate of the utility model uses building materials with a cross section of bow-shaped structure, greatly improves the telescopic gate, particularly improves the intensity and toughness of the telescopic gate, and ensures firmness and durability of the telescopic gate.
Description
Technical field
The utility model relates to a kind of lock, particularly relates to a kind of telescopic door lock.
Background technology
Modern science and technology is maked rapid progress, and various door locks comprise that automatic door lock such as retractable door lock widely apply in the buildings such as factory, guild hall or dwelling house.This telescopic door lock is equipped with power set, only needs simple control, and a lock is opened or closed.
See also Fig. 1, a kind of prior art telescopic door lock 100 comprises that a base station 10 is connected the retractable door 20 of described base station 10 with one one end.Power set and control appliance (figure does not show) are housed in the described base station 10.Described retractable door 20 comprises the gate unit 21 of a plurality of lines arrangements and described a plurality of gates unit 21 is concatenated into one and can drives the latticed gear frame 24 that gate unit 21 stretches.Gate unit 21 is rectangular frames, under wheel 22 is housed, the framework cross section is "] " shape structure (consulting Fig. 2).Hypothesis has pivot 23, pivot 23 to pass the grid lattice point (not indicating) of latticed gear frame 24 in the gate unit 21.
The building materials that gate unit 21 or latticed gear frame 24 are adopted generally are aluminium extruded sectionss.
Under the driving of base station 10 power set, latticed gear frame 24 is applied in the enough poor power of cutting, make the quadrilateral mesh expansion or the convergence of latticed gear frame 24, thereby it is protruding or return base station 10 1 sides to drive gate unit 21, reaches the effect of switch door.
But, because the cross section of gate unit 21 or latticed gear frame 24 building materials is "] " and the shape structure, intensity is not good, might be out of shape or fracture under the ordering about of power set, and the easier damage that is impacted influences life-span of telescopic door lock 100.
The utility model content
Creator of the present utility model is in order to solve the bad shortcoming of prior art telescopic door lock intensity, and through hammer away, putting into practice finally for many years, the utility model telescopic door lock is born.
In order to solve the not good technical problem of prior art telescopic door lock intensity, the utility model provides a kind of high strength, robust telescopic door lock.
The technical scheme that the utility model technical solution problem is taked is: a kind of telescopic door lock is provided, comprise a base station and a retractable door that is connected described base station, this retractable door comprises a plurality of gates unit and described a plurality of gate unit strings is connected into one and can drives the flexible gear frame in gate unit, comprises in this retractable door that the cross section has the building materials of " bow " shape structure.
The beneficial effects of the utility model are: the utility model telescopic door lock significantly promotes the intensity and the toughness of telescopic door lock, particularly retractable door owing to the building materials that adopt the cross section to have " bow " shape structure, guarantees that the telescopic door lock is sturdy and durable.

The specific embodiment
Please consult Fig. 3 together, the utility model telescopic door lock first embodiment 200 comprises that a base station 10 is connected the retractable door 30 of described base station 10 with one one end.Power set and control appliance (figure does not show) are housed in the described base station 10.Described retractable door 30 comprises the gate unit 31 of a plurality of lines arrangements and described a plurality of gates unit 31 is concatenated into one and can drives the latticed gear frame 34 that gate unit 31 stretches.Gate unit 31 is rectangular frames, under wheel 32 is housed.Hypothesis has pivot 33, pivot 33 to pass the grid lattice point (not indicating) of latticed gear frame 34 in the gate unit 31.
See also Fig. 4, the cross section of these gate unit 31 building materials that adopt is the polygons with opening, in the present embodiment, the cross section of described gate unit 31 building materials that adopt has " bow " shape structure 312, and the polygonal-shaped openings end has the support bar 311 of a sealing opening.Equally, the cross section of latticed gear frame 34 building materials that adopt also can have " bow " shape structure.
The building materials that gate unit 31 or latticed gear frame 34 are adopted are high-strength aluminium section bars.
During use, under the driving of base station 10 power set, latticed gear frame 34 is applied in enough scissors power, makes the quadrilateral mesh of latticed gear frame 34 expand or convergence, thereby it is protruding or return base station 10 1 sides to drive gate unit 31, realizes the effect of switch door.
The gate unit 31 of the utility model telescopic door lock 200 is because the building materials that adopt the cross section to have " bow " shape structure 312, significantly promote the intensity and the toughness of retractable door 30, under external impacts, can not be out of shape easily or fracture, guarantee that telescopic door lock 200 is sturdy and durable.
