Technical Field
[0001] The utility model relates to the technical field of curtains, in particular to a curtain handle and a curtain using the same. Background Art
[0002] For simple manual folding curtains, honeycomb curtains, etc., their structures are simple. Usually, a pull rope is used as a track, and the curtain body slides up and down along the pull rope to realize the up-and-down bidirectional opening and closing of the curtain. It is convenient to use. Generally, it includes a curtain body and two upper and lower curtain rods, which are connected with the pull rope. The curtain rod is equipped with a rope buckle for clamping the pull rope, and a handle for the user to pull by hand. The user drives the curtain rod to overcome the clamping force of the rope buckle and slide up and down along the pull rope by pulling the handle. When the user releases the handle, the curtain rod can stay at any position on the pull rope under the action of the clamping force of the rope buckle, realizing the opening and closing of the curtain body at any position, which is convenient to use. However, it is found through use that this structure can be further simplified, and it is more convenient to use, further reducing the assembly of parts and lowering the cost. Content of the Utility Model
[0003] Aiming at the current situation of the above-mentioned prior art, the technical problem to be solved by the utility model is to provide a curtain handle and a curtain using the same, which are not only convenient for the user to open and close the curtain up and down, but also can realize the opening and closing of the curtain body at any position, with fewer parts assembled, lower cost and more convenient to use.
[0004] The technical solution adopted by the utility model to solve the above technical problems is as follows: A curtain handle is connected to a curtain rod. The handle includes a connecting part for connecting the curtain rod and a pulling part for manual pulling. An installation cavity is arranged in the connecting part, a rope hole communicating with the installation cavity is arranged on the connecting part, and a rope clamping assembly for clamping or loosening the pull rope is arranged in the installation cavity. Further, the connecting part includes a turntable, a rotating shaft and a top plate. The turntable is connected to the curtain rod and can rotate relative to the curtain rod. The rotating shaft is connected between the turntable and the top plate. The top plate is integrally formed with the pulling part, and the top plate is exposed outside the curtain rod to expose the pulling part. The installation cavity is located in the rotating shaft and penetrates the turntable, and the rope hole is located on the top plate.
[0005] Further, the rope clamping assembly includes a pressing buckle, an elastic member and a fixing cover. The pressing buckle is horizontally slidably connected to the installation cavity. One end of the elastic member abuts against the inner wall of the installation cavity, and the other end abuts against the end of the pressing buckle. The fixing cover is embedded and buckled at the bottom of the turntable and limits the elastic displacement of the pressing buckle.
[0006] Further, a through hole for passing the drawstring is formed in the extrusion buckle, and a stopper protrudes from the fixed cover. The stopper sequentially passes through the through hole and the rope hole, and the maximum diameters of the through hole and the rope hole are both larger than the maximum length of the stopper. In the natural state, the elastic member pushes the extrusion buckle away from the installation cavity until the inner side wall of the through hole abuts against the front end wall of the stopper. Under the action of an external force, the extrusion buckle slides towards the installation cavity to compress the elastic member until the inner side wall of the through hole abuts against the rear end wall of the stopper.
[0007] Further, a hole for passing the drawstring is formed in the fixed cover, and buckles are symmetrically arranged on both sides of the fixed cover. A clamping groove for cooperating with the buckle is arranged on the turntable.
[0008] Further, a convex column for positioning the elastic member protrudes from one end of the extrusion buckle facing the installation cavity, and an arc surface is arranged at the end of the extrusion buckle facing away from the installation cavity.
[0009] Further, two positioning points are arranged on the handle portion, and the positioning points are located at the junction of the handle portion and the top plate.
[0010] Further, anti-slip lines are arranged on the handle portion.
[0011] A curtain includes a curtain body, an upper curtain rod, a lower curtain rod, a drawstring, and a handle as described above. The curtain body is connected between the upper curtain rod and the lower curtain rod. The drawstrings are symmetrically arranged on the curtain body, and the upper and lower ends of the drawstrings respectively pass through the upper curtain rod and the lower curtain rod. The handle is arranged at the connection of the drawstring and the upper curtain rod and the lower curtain rod. The two ends of the drawstring respectively pass through the rope clamping assembly in the corresponding handle. In the natural state, the rope clamping assembly clamps the drawstring.
[0012] Further, a first track groove for connecting the curtain body and a second track groove for installing the handle are arranged on both the upper curtain rod and the lower curtain rod. Round holes are arranged on both the upper curtain rod and the lower curtain rod, and the round holes communicate with the first track groove and the second track groove. The rope hole on the handle corresponds to the round hole. The turntable on the handle is connected in the second track groove and can rotate relative to the second track groove. The top plate on the handle is exposed outside the second track groove. The rotating shaft on the handle passes through the notch of the second track groove. When the handle rotates to the position overlapping with the upper curtain rod and the lower curtain rod, the extrusion buckle on the handle is squeezed by the inner edge of the notch of the second track groove, and the elastic member is compressed. The rope hole, the through hole, the hole, and the round hole correspond and penetrate to facilitate the passing of the drawstring. When the handle rotates to the position perpendicular to the upper curtain rod and the lower curtain rod, the extrusion buckle on the handle is disengaged from the extrusion of the inner edge of the notch of the second track groove, and the elastic member resets and pushes the extrusion buckle outwards, and the through hole is misaligned with the rope hole and the hole to clamp the drawstring.
[0013] Compared with the prior art, the advantages of the present utility model are as follows: By adding a rope clamping assembly inside the handle, the present utility model uses the elastic clamping force of the rope clamping assembly to clamp the pulling rope. Without external force, the handle can stay at any position on the pulling rope, that is, the clamping force is greater than the gravity of the curtain sagging, so that the curtain can be opened and closed at any position along the pulling rope. At the same time, the user can pull the handle to drive the curtain to open and close up and down. This handle can be used not only to drive the curtain to open and close, but also to open and close the curtain at any position, integrating the functions of the existing handle and the rope buckle, reducing the assembly of parts, having a lower cost, and being convenient to use.

[0030] As Figures 1-6 shown, the present utility model provides a handle for a curtain. The handle 1 is connected to a curtain rod 6. The handle 1 includes a connecting portion 1.1 for connecting to the curtain rod 6 and a pulling portion 1.2 for manual pulling. An installation cavity 1.1.1 is provided inside the connecting portion 1.1. A rope hole 1.1.2 communicating with the installation cavity 1.1.1 is provided on the connecting portion 1.1 for passing a pulling rope 7. A rope clamping assembly for clamping or loosening the pulling rope 7 is provided inside the installation cavity 1.1.1.
[0031] By adding a rope clamping assembly inside the handle 1 in the present utility model, the pulling rope 7 is clamped by the elastic clamping force of the rope clamping assembly. Without external force, the handle 1 can stay at any position on the pulling rope 7, that is, the clamping force is greater than the gravity of the curtain drooping, so that the curtain can be opened and closed at any position along the pulling rope 7. At the same time, the user can pull the handle 1 to drive the curtain to open and close up and down. The handle 1 can be used not only to drive the curtain to open and close, but also to open and close the curtain at any position, integrating the functions of the existing handle and the rope buckle, reducing the assembly of parts, having a lower cost, and being convenient to use.
[0032] Among them, the connecting portion 1.1 includes a turntable 1.1.3, a rotating shaft 1.1.4 and a top plate 1.1.5. The turntable 1.1.3 is connected to the curtain rod 6 and can rotate relative to the curtain rod 6. As the turntable 1.1.3 rotates, the handle 1 can be rotated to a position overlapping with the curtain rod 6, which is convenient for storing the handle 1 during transportation and reducing the space occupation. When in use, the handle 1 can be rotated to a position perpendicular to the curtain rod 6, so as to expose the pulling portion 1.2 for the user to pull the handle 1. The rotating shaft 1.1.4 is connected between the turntable 1.1.3 and the top plate 1.1.5. The top plate 1.1.5 is integrally formed with the pulling portion 1.2. The top plate 1.1.5 is exposed outside the curtain rod 6 to expose the pulling portion 1.2 for the user to pull manually. The installation cavity 1.1.1 is located inside the rotating shaft 1.1.4 and penetrates through the turntable 1.1.3. The rope hole 1.1.2 is located on the top plate 1.1.5, and the pulling rope 7 can pass through the installation cavity 1.1.1 and the rope hole 1.1.2.
[0033] Among them, the rope clamping assembly includes a pressing buckle 2, an elastic member 3 and a fixing cover 4. The pressing buckle 2 is horizontally and slidably connected to the installation cavity 1.1.1. One end of the elastic member 3 abuts against the inner wall of the installation cavity 1.1.1, and the other end abuts against the end of the pressing buckle 2. The elastic contraction of the elastic member 3 enables the pressing buckle 2 to have a telescopic range. The fixing cover 4 is snap-fitted at the bottom of the turntable 1.1.3 and restricts the elastic displacement of the pressing buckle 2. A through hole 2.1 for passing the pulling rope 7 is formed in the pressing buckle 2. A blocking block 4.1 protrudes from the fixing cover 4. The blocking block 4.1 sequentially passes through the through hole 2.1 and the rope hole 1.1.2. The maximum diameters of the through hole 2.1 and the rope hole 1.1.2 are both larger than the maximum length of the blocking block 4.1. In the natural state, the elastic member 3 pushes the pressing buckle 2 away from the installation cavity 1.1.1 until the inner side wall of the through hole 2.1 abuts against the front end wall of the blocking block 4.1. The blocking block 4.1 passes through the through hole 2.1 and can prevent the pressing buckle 2 from moving too far away. When the pressing buckle 2 is subjected to an external force, the pressing buckle 2 slides towards the installation cavity 1.1.1 to compress the elastic member 3 until the inner side wall of the through hole 2.1 abuts against the rear end wall of the blocking block 4.1. The blocking block 4.1 further prevents the pressing buckle 2 from extending too far in, which can play a good limiting role.
[0034] Among them, a hole 4.2 for passing the pulling rope 7 is provided on the fixing cover 4. The hole 4.2 corresponds to the through hole 2.1 and the rope hole 1.1.2 for passing the pulling rope 7. Clasps 4.3 are symmetrically provided on both sides of the fixing cover 4. A clamping groove 1.1.6 for cooperating with the clasps 4.3 is provided on the turntable 1.1.3. The fixing cover 4 and the turntable 1.1.3 are assembled and fastened through the clasps 4.3 and the clamping groove 1.1.6. The assembly is convenient, no additional fixing parts are required, and the cost is lower.
[0035] Among them, a convex column 2.2 for positioning the elastic member 3 protrudes from one end of the pressing buckle 2 facing the installation cavity 1.1.1. The convex column 2.2 can be sleeved with the end of the elastic member 3 to play a limiting role and prevent the elastic member 3 from detaching during use. An arc surface 2.3 is provided at the end of the pressing buckle 2 facing away from the installation cavity 1.1.1. The setting of the arc surface 2.3 facilitates the smooth rotation of the pressing buckle 2 at the assembly position of the curtain rod 6 when the handle 1 rotates, which can play a guiding role and smoothly change the position to realize pressing or loosening the pressing buckle 2.
[0036] Among them, two positioning points 1.2.1 are provided on the pulling part 1.2. The positioning points 1.2.1 are located at the junction of the pulling part 1.2 and the top plate 1.1.5. When the handle 1 is rotated to the position overlapping with the curtain rod 6, the positioning points 1.2.1 just get stuck in the notch of the curtain rod 6, preventing the handle 1 from freely rotating during transportation, and better playing a role in positioning and protection. When the handle 1 is rotated to the position perpendicular to the curtain rod 6, the positioning points 1.2.1 just get stuck on the side of the curtain rod 6, ensuring that the handle 1 is perpendicular to the curtain rod 6 and will not shake left and right, thus facilitating the user to pull the handle 1.
[0037] Among them, anti-slip patterns 1.2.2 are provided on the pulling part 1.2. The anti-slip patterns 1.2.2 are provided on both the front and back of the pulling part 1.2, playing an anti-slip role.
[0038] As Figures 7-8 shown, a curtain includes a curtain body 5, an upper curtain rod 6a, a lower curtain rod 6b, a pull rope 7, and the handle 1 as described above. The curtain body 5 is connected between the upper curtain rod 6a and the lower curtain rod 6b. The pull rope 7 is symmetrically threaded through the curtain body 5, and the upper and lower ends of the pull rope 7 respectively pass through the upper curtain rod 6a and the lower curtain rod 6b. The handle 1 is arranged at the connection of the pull rope 7 with the upper curtain rod 6a and the lower curtain rod 6b. The two ends of the pull rope 7 respectively pass through the rope clamping components in the corresponding handles 1. In the natural state, the rope clamping components clamp the pull rope 7.
[0039] Among them, a first track groove 6.1 for connecting the curtain body 5 and a second track groove 6.2 for installing the handle 1 are provided on both the upper curtain rod 6a and the lower curtain rod 6b. Circular holes 6.3 are provided on both the upper curtain rod 6a and the lower curtain rod 6b for the pull rope 7 to pass through. The circular holes 6.3 communicate with the first track groove 6.1 and the second track groove 6.2. The rope holes 1.1.2 on the handle 1 correspond to the circular holes 6.3. The turntable 1.1.3 on the handle 1 is connected in the second track groove 6.2 and can rotate relative to the second track groove 6.2. The top plate 1.1.5 on the handle 1 is exposed outside the second track groove 6.2. The rotating shaft 1.1.4 on the handle 1 passes through the notch of the second track groove 6.2. When the handle 1 is rotated to the position overlapping with the upper curtain rod 6a and the lower curtain rod 6b, the pressing buckle 2 on the handle 1 presses against the inner edge of the notch of the second track groove 6.2, and the elastic member 3 is compressed. The rope holes 1.1.2, through holes 2.1, holes 4.2, and circular holes 6.3 are correspondingly penetrated to facilitate the passing of the pull rope 7. When the handle 1 is rotated to the position perpendicular to the upper curtain rod 6a and the lower curtain rod 6b, the pressing buckle 2 on the handle 1 is disengaged from the extrusion of the inner edge of the notch of the second track groove 6.2, and the elastic member 3 resets and extrudes the pressing buckle 2 outwards. The through holes 2.1 are misaligned with the rope holes 1.1.2 and the holes 4.2 to clamp the pull rope 7.
[0040] During installation, first fix the two ends of the two draw ropes 7 so that the draw ropes 7 are straightened to form a straight rope ladder. Then rotate the handle 1 on the upper curtain rod 6a and the lower curtain rod 6b forward to expose the pulling part 1.2. The user drives the upper curtain rod 6a and the lower curtain rod 6b to slide up and down along the draw ropes 7 by pulling the handle 1, so as to adjust the curtain body 5 to a suitable position. Since when the user pulls the handle 1, the clamping force of the rope clamping assembly on the draw ropes 7 can be overcome, and when the external force is removed, the elastic force of the elastic member 3 squeezes the extrusion buckle 2 to slide out of the installation cavity 1.1.1, so that the through hole 2.1 is misaligned with the rope hole 1.1.2 and the hole 4.2. At the same time, the inner side wall of the through hole 2.1 is infinitely close to the front end wall of the stopper 4.1, so as to clamp the draw ropes 7 between the inner side wall of the through hole 2.1 and the front end wall of the stopper 4.1, so that the handle 1 is clamped on the draw ropes 7, so that the curtain can be opened and closed at any position on the draw ropes 7. The handle 1 can not only be used to drive the curtain to open and close up and down, but also make the curtain open and close at any position on the draw ropes 7, combining the functions of the existing handle and the rope buckle, reducing the assembly of parts, with lower cost and more convenient use. In addition, when the handle 1 rotates to a position perpendicular to the upper curtain rod 6a and the lower curtain rod 6b, the extrusion buckle 2 is squeezed by the inner edge of the notch of the second track groove 6.2, and the extrusion buckle 2 slides into the installation cavity 1.1.1, the elastic member 3 is compressed, the inner side wall of the through hole 2.1 abuts against the rear end wall of the stopper 4.1, the space between the front end wall of the through hole 2.1 and the stopper 4.1 increases, and is vertically communicated with the rope hole 1.1.2 and the hole 4.2, which can facilitate the insertion or extraction of the draw ropes 7 and facilitate the disassembly and assembly of the draw ropes 7.
[0041] In addition, the elastic member 3 is preferably a spring.
[0042] The materials, reagents and experimental equipment involved in the embodiments of the present utility model are all commercially available products that conform to the curtain field unless otherwise specified.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
