Description

Mosquito net retractable transmission mechanism

The utility model relates to a transmission mechanism for retracting and retracting a mosquito net, in particular to a device for retracting and retracting a mosquito net driven by a pulley and a pull cord.

At present, the common guide rail stretching mosquito net supports on the market all drive the folding or unfolding of the mosquito nets suspended on both sides of the guide rail through pulleys and pull cords, but there are deficiencies in the use process: as proposed by ZL98234450.3 A guide rail stretching type mosquito net support. Although the mosquito net is stable and beautiful, the balance of the pulley and rope transmission mechanism is poor. When the mosquito net is stretched, the two sides of the mosquito net often cannot be synchronized, which greatly affects the flexibility of the mosquito net. .

The purpose of the utility model is to provide a mosquito net retractable transmission mechanism with convenient operation and good balance of the pulley and drawstring transmission mechanism.

The mosquito net retractable transmission mechanism provided by the utility model includes pulleys installed on the top surface bracket of the mosquito net bracket and pull ropes wound on each pulley. A movable cross bar is connected to the pull rope. On the two cross bars of the surface bracket, four double pulleys are arranged side by side on the cross bar close to the wall, and two single pulleys are arranged on the cross bar far away from the wall; there are two pull cords, one of which is One end of the pull rope is tied to one end of the movable cross bar, and the other end is turned around one of the single pulleys on the cross bar far away from the wall and then turned back, and then around the first pulley on the cross bar near the wall. One or one of the two double pulleys sags for a certain distance, then walks around the third and one of the four double pulleys on the cross bar close to the wall, and finally walks around the other pulley on the cross bar away from the wall. A single pulley is tied behind the other end of the movable crossbar; one end of the other stay rope is tied to one end of the movable crossbar, and the other pulley is passed around the first and second ends of the crossbar near the wall. Another pulley in the two double pulleys sags for a certain distance, and then is tied to the other end of the movable cross bar after walking around the third and another pulley in the four double pulleys on the cross bar close to the wall.

For the convenience of tying the stay rope and driving the movable crossbar to move back and forth, the utility model is respectively provided with tie pieces for tying the stay rope at both ends of the movable crossbar and the hanging parts of the two stay ropes respectively. It is connected with a rope pendant that can guide the stay rope vertically up and down.

When the utility model is in use, by pulling any one of the two rope pendants, the stay rope will drive the movable cross bar to move back and forth, thereby driving the mosquito nets suspended on both sides of the guide rail to retract. Compared with the prior art scheme, the utility model has the characteristics of simple structure, convenient operation, good balance of the pulley and rope transmission mechanism, and the synchronous retraction and retraction of both sides of the mosquito net can be realized.

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Fig. 1 is the structural representation of the utility model.

As shown in Figure 1, the mosquito net retractable transmission mechanism of the utility model comprises a pulley installed on the mosquito net bracket top surface support and a stay cord wound around each pulley, and the pulleys are respectively arranged on two cross bars 1, 2, wherein four double pulleys 3a, 3b, 3c, 3d are arranged side by side on the crossbar 1 close to the wall, and two single pulleys 4a, 4b are arranged on the crossbar 2 away from the wall. The utility model has two stay cords, one of which is tied to the tie piece 8 at one end of the movable cross bar 6 with one end of the stay cord 5 , and the other draw end is bypassed on the cross bar 2 far away from the wall. Turn back after one of the single pulleys 4a, then walk around one of the first and second double pulleys 3a, 3b on the cross bar 1 close to the wall and hang down for a certain distance, then connect a rope pendant 9 in series, and then go around Cross a pulley in the third and four double pulleys 3c, 3d on the cross bar 1 close to the wall, and finally go around another single pulley 4b on the cross bar 2 away from the wall and tie it on the other side of the movable cross bar 6 On the binding member 8 at one end; a lifting end of the other stay cord 7 is tied on the binding member 8 at one end of the movable cross bar 6, and the other pulling end goes around the first pulling end on the cross bar 1 close to the wall. 1. The other pulley in the two double pulleys 3a, 3b hangs down for a certain distance, and then connects a rope pendant 10 in series, and then bypasses the third and fourth double pulleys 3c, 3d on the cross bar 1 close to the wall Another pulley in the back is tied on the tie piece 8 of movable cross bar 6 other ends.

For the convenience of the user pulling the rope on the left or right side of the head of the bed, the double pulleys 3b and 3c can be arranged on the left or right side of the cross bar 1 .
