Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rolling curtains, in particular to a one-way balancer for a spring hand-pushed rolling curtain and a spring hand-pushed rolling curtain. Background Art
[0002] Roller blinds are named after the fact that the blinds are rolled up and down by the roller tube, and are widely used in offices, homes, outdoor gardens, etc. Among them, spring hand-pushed roller blinds have won the favor of consumers for their simple design, convenient operation, excellent practicality, and no need for additional motors or power supplies.
[0003] The existing spring hand-pushed roller blinds apply upward or downward force to the bottom of the curtain with the hand, and use a spring mechanism to realize the raising and lowering of the curtain, wherein the winding force of the torsion spring is equal to the weight of the curtain. When the user applies upward or downward force to the bottom of the curtain with the hand to move the curtain up or down, the torque force of the torsion spring needs to be balanced with the torque generated by the gravity of the curtain, so that the curtain can stay wherever the user wants.
[0004] Since the torque of the torsion spring needs to be balanced with the torque generated by the weight of the curtain, the torque of the torsion spring needs to be constantly selected and adjusted during the production process to match curtains of different materials and sizes. The requirements for torsion springs are high, resulting in the need to customize corresponding torsion springs for each roller blind, which leads to low efficiency and high production costs. In addition, the same specification of torsion springs cannot be adapted to curtains of different materials and sizes, and the versatility is low. At the same time, after long-term use, the torque of the torsion spring is prone to deviation or reduction due to deformation or aging. When the customized torque becomes smaller, the torque of the spring will be less than the torque of the curtain weight, causing the curtain to slide down due to its own weight, which cannot meet the user's need to stay in a certain position accurately.
[0005] Therefore, it is urgent to design a one-way balancer for a spring hand-pushed rolling curtain and a spring hand-pushed rolling curtain, which can ensure that the curtain cloth will not slide down due to its own weight, so that the curtain cloth can stay in the preset position more accurately, and reduce the balance requirements between the torque force of the torsion spring and the torque generated by the gravity of the curtain cloth, so that it can adapt to curtain cloths of different materials and sizes, with high versatility and high practicality. At the same time, it effectively reduces the production cost, improves the adjustment efficiency and the number of pre-tightening circles of the torsion spring, and has a simple structure, which effectively meets the needs of users.

[0009] In a preferred technical solution of the present application, a plurality of needle roller grooves are provided on the outer periphery of the balancing shaft sleeve; the distance between the bottom of any one of the needle roller grooves and the balancing shaft cover decreases successively in a clockwise or counterclockwise direction; and the needle roller is arranged in the needle roller groove.
[0010] In a preferred technical solution of the present application, the number of the needle roller grooves is 3.
[0011] In a preferred technical solution of the present application, a plurality of needle stop grooves are further provided on the outer periphery of the balancing sleeve; the needle stop grooves and the needle roller grooves are distributed along the circumferential direction of the balancing sleeve and are connected to the needle roller grooves.
[0012] In a preferred technical solution of the present application, the one-way balancing assembly also includes a stopper needle; the stopper needle is arranged in the stopper needle groove and abuts against the groove wall of the stopper needle groove; a stopper rod is provided on the stopper needle, and the stopper rod extends out of the stopper needle groove and extends in the direction of the roller needle groove.
[0013] In a preferred technical solution of the present application, a threaded through hole is provided at one end of the main shaft body; when the main shaft body passes through the balancing shaft sleeve and the balancing shaft cover, the main shaft body is connected to the balancing shaft cover by connecting the screws with the threaded through hole.

[0016] The second purpose of the present application is to provide a spring hand-pushed roller blind, including the one-way balancer for the spring hand-pushed roller blind mentioned above.
[0017] The technical solution provided by this application may have the following beneficial effects:
[0018] The one-way balancer for spring hand-pushed roller blinds provided in the present application comprises a main shaft body, a transmission spring, a one-way balancing assembly and a balancing shaft cover. When the curtain stops and slides down due to its own weight, a roller needle is stuck between the balancing shaft cover and the balancing shaft sleeve, thereby greatly increasing the friction between the balancing shaft cover and the balancing shaft sleeve, making it impossible for the balancing shaft cover and the balancing shaft sleeve to rotate, and acting on the roller tube synchronously, effectively preventing the roller tube from rotating, thereby stopping the curtain and allowing the curtain to stay in the preset position more accurately.
[0019] Since the hand-pushed rolling curtain one-way brake can effectively prevent the curtain from sliding down due to its own weight, the counterweight of the bottom rail can be increased to increase the number of pre-tightening turns of the torsion spring. Moreover, since there is no need to maintain a precise balance between the torque force of the torsion spring and the torque generated by the gravity of the curtain, it can be adapted to curtains of different materials and sizes, and has high versatility and strong practicality.
[0020] Compared with the existing spring hand-pushed rolling curtain, the one-way balancer provided by the present application can ensure that the curtain will not slide down due to its own weight, so that the curtain can stay in the preset position more accurately, reducing the balance requirements between the torque force of the torsion spring and the torque generated by the gravity of the curtain, so that it can adapt to curtains of different materials and sizes, with high versatility and high practicality. Moreover, because it prevents the curtain from falling in one direction, when the curtain rises, the one-way brake does not generate resistance to the roller tube, so that the curtain can rise faster and more labor-saving, improving the user experience.
[0021] It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] During the production process of the current spring hand-pushed roller blinds, it is necessary to constantly select and adjust the torque of the torsion spring to match the curtains of different materials and sizes. The precision of the torsion spring is high, and the torsion spring of the same specification cannot be adapted to the curtains of different materials and sizes, and the versatility is low. At the same time, after long-term use, the torsion spring is prone to deformation or aging, resulting in deviation or reduction of the torque, causing the curtain to slide down due to its own weight, which cannot meet the user's need to stay accurately at a certain position.
[0035] In response to the above problems, the embodiments of the present application provide a one-way balancer for a spring hand-pushed roller blind, which can ensure that the curtain will not slide down due to its own weight, so that the curtain can stay in the preset position more accurately, reducing the balance requirement between the torque force of the torsion spring and the torque generated by the gravity of the curtain, so that it can adapt to curtains of different materials and sizes, has high versatility, simple structure, low cost, and effectively meets the needs of users.
[0036] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.
[0037] Embodiment 1
[0038] See also Figure 1-Figure 6 The one-way balancer for the spring hand-pushed roller blind of the present application comprises a main shaft body 1, a transmission spring 2, a one-way balance component and a balance shaft cover 4, wherein the main shaft body 1, the transmission spring 2, the one-way balance component and the balance shaft cover 4 are arranged in sequence from the inside to the outside. In order to improve the strength and stability of the one-way balancer, the main shaft body 1, the one-way balance component and the balance shaft cover 4 are preferably made of stainless steel or aluminum alloy.
[0039] The spindle body 1 includes a main shaft 11 and a connecting end 12 . The cross-sectional shapes of the main shaft 11 and the connecting end 12 are both circular, and the connecting end 12 is arranged at one end of the main shaft 11 .
[0040] The transmission spring 2 is sleeved on the main shaft body 1 and has an interference fit with the main shaft body 1. Specifically, the transmission spring 2 is sleeved on the main shaft 11 and has an interference fit with the main shaft 11, so that the transmission spring 2 can rotate with the rotation of the main shaft 11. Figure 1 and Figure 3 As shown, the transmission spring 2 further includes a convex portion, which is arranged at one end of the transmission spring 2 and extends in an axial direction perpendicular to the main shaft 11. Preferably, the convex portion is arranged at one end of the transmission spring 2 close to the connecting end 12 or is staggered at both ends of the transmission spring 2, so that the transmission spring 2 can better transfer the kinetic energy on the main shaft 11 to the one-way balancing assembly.
[0041] The one-way balancing assembly includes a balancing sleeve 31 and a needle roller 32; the balancing sleeve 31 is connected to the transmission spring 2, and the needle roller 32 is movably arranged between the balancing sleeve 31 and the balancing shaft cover 4, so that the balancing sleeve 31 can only rotate clockwise or counterclockwise. Figure 3 As shown, a strip groove 33 is provided on the inner side of the shaft of the balancing sleeve 31, and the extension direction of the strip groove 33 is parallel to the axial direction of the main shaft body 1. The convex portion of the transmission spring 2 is provided in the strip groove 33 and abuts against the groove wall of the strip groove 33. In order to increase the contact area between the convex portion and the strip groove 33 to increase the abutment force, the convex portion is L-shaped as a whole, and the width of the strip groove 33 is adapted to the thickness of the transmission spring 2.
[0042] The outer periphery of the balancing shaft sleeve 31 is provided with a plurality of needle roller grooves 34, and the distance between the groove bottom of any needle roller groove 34 and the balancing shaft cover 4 decreases in a clockwise or counterclockwise direction, that is, the groove pitch of the needle roller groove 34 decreases in a clockwise or counterclockwise direction, and the end with the largest groove pitch is adapted to the needle roller 32, so that the needle roller 32 can be arranged in the needle roller groove 34. It should be noted that the groove pitch is the distance between the groove bottom and the balancing shaft cover 4.
[0043] Furthermore, when the balancing sleeve 31 moves in the direction of decreasing the slot pitch, in order to stop the needle roller 32 from moving in the direction of maximum slot pitch, the one-way balancing assembly further includes a stopper needle 36. The outer periphery of the balancing sleeve 31 is further provided with a plurality of stopper needle grooves 35. The stopper needle grooves 35 and the needle roller grooves 34 are distributed along the circumferential direction of the balancing sleeve 31 and are connected with the needle roller grooves 34. The stopper needle 36 is arranged in the stopper needle groove 35 and abuts against the groove wall of the stopper needle groove 35. The stopper needle 36 is provided with a stopper rod 361, which extends out of the stopper needle groove 35 and toward the direction of the needle roller groove 34.
[0044] For example, Figure 1 and Figure 3 As shown, the number of the needle roller groove 34 and the needle stopper groove 35 are both 3, one needle roller 32 is provided in the needle roller groove 34, and two stopper needles 36 are provided in the needle stopper groove 35, and the two stopper needles 36 are symmetrically arranged, and a stop rod 361 extends from the needle stopper groove 35 into the needle roller groove 34 and abuts against the needle roller 32.
[0045] Furthermore, the one-way balancer also includes a mounting code 5, and the main shaft body 1 is connected to the mounting code 5 and the balancing shaft cover 4 respectively. Specifically, the mounting code 5 is provided with a folding piece 51, and one end of the main shaft body 1 is provided with a fixing slot 13, and the folding piece 51 is inserted in the fixing slot 13. The balancing shaft cover 4 is sleeved on the main shaft body 1, and the other end of the main shaft body 1 is provided with a threaded through hole. When the main shaft body 1 passes through the balancing shaft sleeve 31 and the balancing shaft cover 4, the main shaft body 1 is connected to the balancing shaft cover 4 by connecting the screws with the threaded through holes. Exemplarily, as Figure 1 and Figure 4 As shown, the end of the main shaft 11 away from the connecting end 12 is provided with a threaded through hole, and the end of the connecting end 12 away from the main shaft 11 is provided with a fixing slot 13. After the balancing shaft sleeve 31 and the balancing shaft cover 4 are sleeved on the main shaft 11, the screw is fixed in the threaded through hole. At this time, the nut of the screw is respectively in contact with the main shaft 11 and the balancing shaft cover 4. By inserting the folding piece 51 in the fixing slot 13, the main shaft body 1 is fixed on the mounting code 5.
[0046] Working principle:
[0047] After the one-way balancer is applied to the spring hand-pushed roller blind, when the user applies an upward force to the bottom of the curtain with his hand to make the curtain rise, the torsion spring releases energy and the roller tube rotates clockwise. At this time, the main shaft 11 connected to the torsion spring has a tendency to rotate clockwise, driving the transmission spring 2, the balancing shaft sleeve 31 and the needle roller 32 to synchronously have a tendency to rotate clockwise. Since the movement direction of the needle roller 32 is in the direction of increasing the slot pitch, the needle roller 32 can fully rotate, so that the main shaft 11, the transmission spring 2, the balancing shaft sleeve 31 and the needle roller 32 can synchronously rotate clockwise. At this time, since the needle roller 32 will not give friction to the balancing shaft cover 4, the curtain can be raised faster and more labor-saving. When the curtain stops, the hand force is withdrawn, and the curtain has a downward movement tendency under the action of its own gravity, driving the winding tube and the balancing shaft cover 4 to have a rotation (i.e., counterclockwise rotation), thereby driving the needle roller 32 to have a counterclockwise rotation tendency. Since the movement direction of the needle roller 32 is in the direction of smaller slot pitch, the needle roller 32 cannot rotate, and is thus stuck between the balancing shaft cover and the balancing shaft sleeve, so that the friction between the balancing shaft cover 4 and the balancing shaft sleeve 31 is greatly increased, thereby preventing the balancing shaft cover 4 and the winding tube from rotating counterclockwise, thereby stopping the curtain.
[0048] In the first embodiment of the present invention, the one-way balancer for the spring hand-pushed roller blind provided in the present application includes a main shaft body, a transmission spring, a one-way balancing assembly and a balancing shaft cover. When the curtain stops and slides down due to its own weight, the roller needle is stuck between the balancing shaft cover and the balancing shaft sleeve, which greatly increases the friction between the balancing shaft cover and the balancing shaft sleeve, making it impossible for the balancing shaft cover and the balancing shaft sleeve to rotate, and acting on the roller tube synchronously, effectively preventing the roller tube from rotating, thereby stopping the curtain and allowing the curtain to stay in the preset position more accurately.
[0049] Since the hand-pushed rolling curtain one-way brake can effectively prevent the curtain from sliding down due to its own weight, the counterweight of the bottom rail can be increased to increase the number of pre-tightening turns of the torsion spring. Moreover, since there is no need to maintain a precise balance between the torque force of the torsion spring and the torque generated by the gravity of the curtain, it can be adapted to curtains of different materials and sizes, and has high versatility and strong practicality.
[0050] Compared with the existing spring hand-pushed rolling curtain, the one-way balancer provided by the present application can ensure that the curtain will not slide down due to its own weight, so that the curtain can stay in the preset position more accurately, reducing the balance requirements between the torque force of the torsion spring and the torque generated by the gravity of the curtain, so that it can adapt to curtains of different materials and sizes, with high versatility and high practicality. Moreover, because it prevents the curtain from falling in one direction, when the curtain rises, the one-way brake does not generate resistance to the roller tube, so that the curtain can rise faster and more labor-saving, improving the user experience.
[0051] Embodiment 2
[0052] Corresponding to the above-mentioned one-way balancer, the present application also provides a spring hand-pushed roller blind, see Figure 1-Figure 6 , specifically:
[0053] Based on the structure of the above-mentioned embodiment 1, the spring hand-pushed rolling curtain provided in the second embodiment includes a rolling tube, a curtain, a torsion spring and the above-mentioned one-way balancer for the spring hand-pushed rolling curtain. The mounting code 5 is fixed to the wall by screws, the rolling tube is sleeved on the one-way balancer for the spring hand-pushed rolling curtain, the curtain is rolled on the rolling tube, and the torsion spring is connected to the main shaft 11.
[0054] The specific structure of the one-way balancer for the spring hand-pushed roller blind is detailed in the above-mentioned embodiment 1 and will not be repeated here.
[0055] In the description of the present application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description.
