Abstract
The utility model relates to a traction mechanism for a curtain. The utility model comprises a fixed block, a bracing cable, a drive motor and a control device. The fixed block has two kind of installing modes, one kind of the installing modes is that a through hole through which the bracing cable passes is arranged on the fixed block on a fixed plate, and the other kind of the installing modes is that the fixed block is also provided with a guideway; elastic buffering mechanisms are all arranged on the fixed block at one end, and the bracing cable passes round fixed rings on the buffering mechanisms. The buffering mechanisms which are fixed on one side of the fixed block comprise positioning sheets and buffering screw bolts. A compression spring is sheathed on a screw bolt between a nut of a screw bolt and the positioning sheet, and the fixing ring is arranged on the top of the buffering screw bolt. The installing direction of the buffering screw bolt can be perpendicular or parallel to the run of the bracing cable. The utility model which slightly deforms the traditional fixed block is additionally provided with the buffering mechanism, the bracing cable can be moved at any time and any place, starting impact energy is absorbed by means of the buffering mechanism, the bracing cable obtains appropriate tension, and the flexibility and the service life of the complete curtain device are enhanced.
Description
Technical field
The utility model relates to a kind of curtain haulage gear, is meant a kind of traction buffer gear of electrically driven curtain especially.
Background technology
Along with growth in the living standard, curtain with low cost, that pattern is various is subjected to liking of people day by day as the necessary article that beautifies, decorates the room and keep the sun off.In the installation and use of curtain, great majority are with requiring curtain can spur arbitrarily as required, close and close or open per family, so manufacturer has designed manually and the electrically driven curtain guide rail according to market demand, and fix a slide plate and drag-line fixed block on guide rail or in the pelmet at a certain distance, borrow the drag-line fixed block not only to keep the position of drag-line but also can control the position and the moving process of curtain easily.Because the drag-line that generally is fixed in the curtain rail is only borrowed drag-line fixed block holding position, in manual or electronic traction process, drag-line often need bear bigger moment pulling force, this moment pulling force very easily cause the drag-line fracture and damage.To this, relevant by retrieval openly Chinese patent does not find how to overcome the report of the suffered force of the breath of drag-line as yet.
Summary of the invention
The purpose of this utility model provides a kind of buffer gear that absorbs the suffered instant impact of drag-line.
Designed a kind of curtain haulage gear according to above-mentioned purpose, comprise the fixed block and the drag-line that keep the drag-line position, drag-line is subjected to the control of motor and control device, the mounting means of fixed block has two kinds, the first is installed in and has the through hole that passes for drag-line on the fixed block on the fixed head, and the fixed block that is positioned at the end is provided with an elastic buffering mechanism; It two is that the curtain haulage gear also includes guide rail, and the fixed block that is positioned at rail end is provided with an elastic buffering mechanism; Drag-line is all worn the retainer ring of walking around on the described buffer gear.This buffer gear is fixed on a side of fixed block, comprises spacer, passes the buffering bolt of through hole on the spacer, is equipped with the compression spring on the bolt between bolt and nut and the spacer.At the fixed block of one, retainer ring is arranged on the top of buffering bolt, and the installation direction of buffering bolt is vertical with the drag-line trend; At its fixed block of two, retainer ring is arranged on the top of buffering bolt, the fixed block in retainer ring the place ahead is provided with a king pin that supplies drag-line to turn to, the installation direction of buffering bolt moves towards parallel with drag-line, at this moment have the guide groove that passes through for drag-line in the fixed block upper end, this guide groove one-in-and-one-out has two, and the width of notch is less than groove width.
The utility model is out of shape a little by the conventional fixed piece that is arranged on the curtain rail termination and with it sets up a buffer gear simultaneously, both guaranteed that drag-line can move according to user's demand whenever and wherever possible, absorbed the energy that generation is impacted to drag-line when starting by buffer gear again, make drag-line both obtain suitable tension force, improved the flexibility and the service life of a whole set of window shade arrangement again.
Description of drawings
Accompanying drawing 1 is the utility model embodiment one assembly structure schematic perspective view; Accompanying drawing 2 is assembly structure schematic perspective views of another embodiment of the utility model; Accompanying drawing 3 is parts decomposing schematic representations of accompanying drawing 2.
Specific embodiments
Accompanying drawing 1 is given the assembly structure that has shown embodiment one signal, and the structure of its buffer gear is identical with embodiment two, be a side that is fixed on fixed block 30 by spacer 33, but the structure of fixed block and embodiment two has bigger difference.On the fixed block that keeps the drag-line position, be provided with the through hole that passes for drag-line 20, and omitted guide rail; Article one, drag-line passes the retainer ring of wearing again behind the fixed block of termination in the bypass buffer mechanism 41, and the installation direction of buffering bolt moves towards vertical with drag-line.
Accompanying drawing 2,3 is given the assembly structure that has shown another embodiment signal, and the upper end that is positioned at the fixed block 30 of guide rail 10 ends is provided with the guide groove 31 that makes drag-line 20 location and commutation, the rectangular shape of guide groove, and the A/F on the guide groove is less than the width of guide groove; Guide groove has two, uses for the revolution of drag-line one-in-and-one-out; The drag-line that passes guide groove is worn the retainer ring 41 in the bypass buffer mechanism with after walking around king pin 32, passes from another guide groove and returns the guide rail.Buffer gear comprises the spacer 33 of a side that is fixed on fixed block, buffering bolt 40 is nested with compression spring 50 after passing through hole on the spacer on bolt, the other end of this compression spring is by bolt and nut 60 location, retainer ring is arranged on the top of bolt, and the installation direction of buffering bolt moves towards parallel with drag-line.
