Abstract
The utility model discloses an electric venetian blind with an improved structure. The electric venetian blind comprises vanes, a vane turnover mechanism and a vane lifting mechanism, wherein the travel positioning component of the vane lifting mechanism comprises an upper travel switch and a lower travel switch assembly; the lower travel switch assembly comprises a lower travel switch, a switch pressing handle and a return spring; the lower travel switch is arranged at the end side of a winding reel support and the trigger piece of the lower travel switch is over against the end side of the winding reel support; the switch pressing handle is formed integrally from a cylindrical sleeve and a compression block; the cylindrical sleeve is movably sleeved to a winding sliding rod, while the compression block is located outside the winding reel support and over against the trigger piece of the lower travel switch; and the return spring is movably sleeved to the winding sliding rod and arranged between the inner side of the winding reel support and the cylindrical sleeve of the switch pressing handle. The electric venetian blind provided by the utility model has the advantages that the travel positioning component is improved, the upper travel switch is started under triggering of the rising vanes so that accurate positioning of the vanes during rising can be realized, and the switch pressing handle is driven by the action of the winding slider when the vanes are falling so as to trigger and start the lower travel switch; in this way, accurate positioning of the vanes while falling can be realized; and therefore, the accuracy is improved and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of sun blind, belongs to the awning blind technical field, refers in particular to a kind of electric blind window curtain that improves structure.
Background technology
At present, often can use sun blind in the environment such as home dwelling, office or hotel, existing sun blind are divided into manually and electronic two kinds.When using manual louver curtain, when the blade lifting that needs the adjusting louver curtain or flip angle, be generally all to realize by the stay cord that adjustment ties up on shutter, it is convenient not to use; And existing electric blind window curtain, generally realize lifting and the upset of blade by motor-driven, convenient for control, but and far distance controlled, certainly, in order to realize the location of blade automatic lifting, usually all stroke controlling structure can be set, but the accurate not shortcoming of stroke controlling structure ubiquity Stroke Control now haves much room for improvement.
The utility model content
The purpose of this utility model is to overcome shortcoming of the prior art with not enough, and a kind of simple and compact for structure, registration, durable reliable electric blind window curtain are provided.
To achieve these goals, the utility model is realized according to following technical scheme:
a kind of electric blind window curtain that improves structure, include blade, the blade switching mechanism, and blade elevating mechanism, wherein, described blade elevating mechanism includes the motor that is in transmission connection and coordinates, power transmission shaft, several spool assemblies and stroke positioning element, each spool assembly includes the spool support of location use, spool and spiral slide block that interlock coordinates, reaching is the spiral slide bar of spiral slider guide, and the stroke positioning element includes upper stroke switch and lower stroke switch assembly, the lower stroke switch assembly includes lower stroke switch, switch pressure handle and back-moving spring, lower stroke switch is arranged at the distolateral of spool support and its and triggers sheet this is distolateral over against the spool support, the switch pressure handle is one-body molded by jacket casing and briquetting, the jacket casing activity is set on the spiral slide bar, briquetting is positioned at the spool support outside and over against the triggering sheet of lower stroke switch, the back-moving spring activity be set on the spiral slide bar and be placed in spool support inboard and switch pressure handle jacket casing between.
Further, it is distolateral and be positioned at the superiors' blade top that described upper stroke switch is arranged at another of spool support, and it triggers sheet and contacts to trigger towards the superiors' blade and with the superiors blade clutch contacts upper stroke switch work of controlling.
The utility model compared with prior art, its beneficial effect is:
By improving the stroke positioning element, utilize the blade that rises to trigger and start upper stroke switch, can realize the accurate location that blade rises, and the action of spiral slide block drives the switch pressure handle when utilizing blade to descend, and then triggering starts lower stroke switch, can realize the accurate location that blade descends, improve precision, and extended application life.
In order to understand more clearly the utility model, set forth the specific embodiment of the present utility model below with reference to description of drawings.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of blade elevating mechanism.
The specific embodiment
As shown in Figure 1, 2, the electric blind window curtain of improvement structure described in the utility model, include blade 1, blade switching mechanism, reach blade elevating mechanism 2, wherein, described blade elevating mechanism 2 includes motor 21, power transmission shaft 22, several spool assemblies and the stroke positioning element that is in transmission connection and coordinates.
Above-mentioned spool assembly includes spool 24 that the spool support 23, interlock of location use coordinate and spiral slide block 25, and is the spiral slide bar 26 of spiral slider guide, wherein, spool 24 is fastenedly connected with power transmission shaft 22, spiral slide block 26 and spool 24 threaded can move left and right along spiral slide bar 26 under spool 24 rotatory force effects.
above-mentioned stroke positioning element includes upper stroke switch and lower stroke switch assembly, the lower stroke switch assembly includes lower stroke switch 31, switch pressure handle 32 and back-moving spring 33, lower stroke switch 31 is arranged at the distolateral of spool support 23 and its and triggers sheet 311 this is distolateral over against spool support 23, switch pressure handle 32 is one-body molded by jacket casing 321 and briquetting 322, jacket casing 321 activities are set on spiral slide bar 26, briquetting 322 is positioned at spool support 23 outsides and over against the triggering sheet 311 of lower stroke switch 31, back-moving spring 33 activities be set on spiral slide bar 26 and be placed in spool support 23 inboards and switch pressure handle jacket casing 321 between.Further, it is distolateral and be positioned at the superiors' blade 11 tops that described upper stroke switch 34 is arranged at another of spool support 23, and it triggers sheet 341 and contacts to trigger towards the superiors' blade 11 and with the superiors blade 11 clutch contacts the upper stroke switch work of controlling.
The operating principle of this stroke positioning element is as described below: motor rises by power transmission shaft and spool assembly band moving vane, when the superiors' blade rises to when contacting with the triggering sheet contact of upper stroke switch, at once trigger upper stroke switch, motor quits work, and blade stops rising; And motor is when descending by power transmission shaft and spool assembly band moving vane, the spiral slide block moves towards switch pressure handle direction, until contact with the jacket casing contact of switch pressure handle, and then pull switch pressure handle compression reseting spring moves to the lower stroke switch direction, until the briquetting of switch pressure handle contacts with the triggering sheet contact of lower stroke switch, trigger lower stroke switch, motor quits work immediately, and blade also stops descending.
The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model and modification are not broken away from spirit and scope of the present utility model, if within these changes and modification belonged to claim of the present utility model and equivalent technologies scope, the utility model also was intended to comprise these changes and modification.
