Go up movable clamp 11 and be equipped with first fixed pulley 3 and two at least second fixed pulleys 4, first fixed pulley 3 is located the one side of keeping away from the hinged end, a plurality of equidistant range of second fixed pulley 4 are by first fixed pulley 3, lower movable clamp 12 is equipped with at least one friction cylinder 5, when last movable clamp 11 and lower movable clamp 12 were closed, friction cylinder 5 was located the clearance of two adjacent second fixed pulleys 4, and friction cylinder 5 and wear to establish the contact of (window) curtain stay cord 2 in the auto-lock structure. The upper movable clamp and the lower movable clamp are both of groove-type structures and are used for accommodating the first fixed pulley, the second fixed pulley and the friction cylinder.
The working principle of the utility model is as follows:
as shown in fig. 3, when the self-locking structure of the present invention is applied to a lifting curtain, the curtain cord 2 passes under the second fixed pulleys 4 and bypasses above the fixed pulleys 3, when the lifting curtain is in a static state, two ends of the curtain cord are respectively pulled by the curtain bottom rod and the lifting control member, the curtain cord is straightened, and under the gravity action of the curtain bottom rod 81, the first fixed pulley 3 is subjected to a large downward force, so that the upper movable clamp 11 rotates around the hinged end, the lower movable clamp 12 approaches, the self-locking structure is closed, and the torsion spring is in a tense state.
As shown in fig. 2, when the upper movable clamp 11 and the lower movable clamp 12 are closed, the friction cylinder 5 is clamped into a gap between two adjacent second fixed pulleys 4, the friction cylinder 5 and the second fixed pulleys 4 are arranged in a straight line, the curtain pull rope 2 winds around the second fixed pulleys 4 and the friction cylinder 5 at intervals, and the curtain pull rope 2 is in contact with the friction cylinder 5 and is extruded to generate friction resistance to clamp the curtain pull rope, so as to prevent the curtain bottom rod from sliding downwards.
According to the utility model, the self-locking structure is arranged on the curtain pull rope of the lifting curtain, the curtain pull rope is clamped by closing the upper movable clamp and the lower movable clamp and extruding and rubbing the curtain pull rope by the friction cylinder inside the upper movable clamp and the lower movable clamp, so that the lifting curtain is in a static state without being subjected to external force, the problem that the bottom rod of the large-size lifting curtain does not automatically slide is solved, the curtain bottom rod is accurately stopped at a certain required height by a user, and the user experience is improved.
The friction resistance depends on the friction coefficient of the surface of the friction cylinder and the setting number of the friction cylinders, the friction coefficient is a fixed value, the friction resistance is changed by changing the number of the friction cylinders by a user, and the number of the friction cylinders is configured according to the weight of the bottom rod of the curtain. In addition, the number of the friction cylinders is matched with that of the second fixed pulleys, namely, one friction cylinder is arranged in the gap between every two second fixed pulleys, so that when the upper movable clamp and the lower movable clamp are closed, the curtain pull rope winds around the second fixed pulleys and the friction cylinders in an S shape, and the figure 2 is shown.
As shown in fig. 4, when the lifting curtain needs to be lifted or lowered, the user only needs to move the lifting control member 7 slightly upwards, the curtain pull rope in the self-locking structure is loosened, the downward pressure on the first fixed pulley is reduced and is smaller than the elastic force of the torsion spring, the upper movable clamp and the lower movable clamp are separated, the self-locking structure is opened, and the user can lift or lower the lifting curtain.
In this embodiment, the hinged end of the upper movable clamp 11 is provided with a rope inlet 6, and the curtain rope 2 connected with the lifting control member 7 enters the self-locking structure 1 from the rope inlet 6.
In a preferred embodiment, the head end of the upper movable clamp 11 protrudes beyond the lower movable clamp 12 to form a protrusion, where the first fixed pulley 3 is located. The structural design is convenient for the curtain pull rope 2 to directly go out downwards after winding around the first fixed pulley 3.
On the other hand, the utility model provides a lifting curtain, which comprises a curtain frame, a curtain bottom rod 81, a curtain pull rope 2 and a lifting control piece 7, wherein the curtain bottom rod 81, the curtain pull rope 2 and the lifting control piece 7 are positioned in the curtain frame, the lifting curtain also comprises a self-locking structure used for lifting the curtain in the scheme, one end of the curtain pull rope 2 is connected with the curtain bottom rod 81, and the other end of the curtain pull rope penetrates through the self-locking structure 1 and is connected with the lifting control piece 7.
The curtain body 82 of the lifting curtain is a blind sheet or honeycomb curtain paper, and the curtain pull rope 2 penetrates through the curtain body 82 and bypasses the steering wheel 83 at the top, so that the self-locking structure 1 is steered.
The use method of the lifting curtain comprises the following steps:
when the lifting curtain is put down, the lifting control piece 7 is slightly moved upwards, at the moment, the pulling force of the curtain pull rope 2 on one side of the lifting control piece 7 disappears suddenly, the curtain pull rope 2 is loosened, the pressure on the first fixed pulley 3 is reduced, the upper movable clamp 11 tilts upwards under the action of the torsion spring, and the self-locking structure is opened; the curtain bottom rod 81 moves upwards continuously along with the lifting control piece 7, smoothly pulls the curtain pull rope 2 and descends downwards to finish curtain releasing;
when the lifting control member 7 is about to stop, the pulling force of the lifting control member 7 on the curtain pulling rope 2 is gradually increased, the curtain pulling rope is stretched straight under the combined action of the pulling forces on the two sides of the curtain pulling rope 2, the downward acting force applied to the first fixed pulley 3 is gradually increased, the self-locking structure is slowly closed and clamps the curtain pulling rope, and the curtain bottom rod stably stops at the target position.
When the lifting curtain is lifted, the lifting control piece 7 is moved upwards firstly, after the self-locking structure is opened, the lifting control piece 7 is pulled downwards, the curtain bottom rod 81 continuously rises under the pulling of the lifting control piece 7, due to the continuous pulling of the curtain pull rope 2, under the continuous rotation of the first fixed pulley 3, the pressure acting on the first fixed pulley 3 is smaller than the elastic force of the torsion spring, the self-locking structure is always kept in an opening state, after the curtain lifting operation is finished, similarly, the lifting control piece is stopped, the curtain pull rope is stretched straight, the downward acting force applied to the first fixed pulley 3 is gradually increased, the self-locking structure is slowly closed and clamps the curtain pull rope, and the lifting curtain is in a balanced static state.
In summary, the self-locking structure is arranged on the curtain pull rope of the lifting curtain, so that the phenomenon that the bottom rod of the large-size lifting curtain does not automatically slide is solved, a user can accurately stop the bottom rod of the curtain at a certain required height, and the user experience is improved.
