Since both ends of the two wire ropes are fixed, when the force deviates from the middle of the pull rod, it is very easy to cause the tension of the two wire ropes to be inconsistent, so that the two ends of the pull rod are prone to move out of sync, which can easily lead to unbalanced pulling of the roller blind. Therefore, it is not suitable to pull the roller blind at any point, which brings considerable trouble to the user.

[0003] Therefore, it is very necessary to design an elastic structure of a roller blind positioning rope to solve the above technical problems. Utility Model Content

The second type, the rolling guide body is a guide wheel, and the two positioning ropes are both wound around the guide wheel. The third type, the rolling guide body is a guide roller, and the two positioning ropes are both wound around the guide roller.

[0009] Preferably, the roller blind positioning rope elastic structure further comprises a cross bar, and the two rolling guide bodies are respectively arranged on the left and right ends of the cross bar.

[0010] Preferably, the roller blind positioning rope elastic structure further comprises a clamping screw, and the other end of the positioning rope is wound around or sleeved on the clamping screw.

[0019] like Figure 1As shown, the utility model describes an elastic structure of a roller blind positioning rope, comprising an elastic holding member 1, two rolling guide bodies 2, and two positioning ropes 3. The two rolling guide bodies 2 are arranged side by side left and right, and the rolling center lines of the two rolling guide bodies 2 extend longitudinally (the longitudinal direction is the front-to-back direction), and the elastic holding member 1 is arranged above between the two rolling guide bodies 2, and the elastic direction of the elastic holding member 1 is horizontal; one end of one of the positioning ropes 3 is connected to the left end of the elastic holding member 1, and the other end of the positioning rope 3 is sequentially moved to the left, downward, around the bottom of the left rolling guide body 2, and then to the right, around the top of the right rolling guide body 2, and then fixed downward; one end of the other positioning rope 3 is connected to the right end of the elastic holding member 1, and the other end of the positioning rope 3 is sequentially moved to the right, downward, around the bottom of the right rolling guide body 2, and then to the left, around the top of the left rolling guide body 2, and then fixed downward.

[0020] In the elastic structure of the roller blind positioning rope, an elastic holding part 1 with a horizontal elastic direction is used to elastically hold the two positioning ropes 3, which can keep the tension of the two positioning ropes consistent, which can help improve the balance of the up and down movement of the roller blind, and can help pull the roller blind at any point without deviation and displacement, with good synchronization and easy operation, which can solve a lot of troubles for users.

[0021] like Figure 1 As shown, the elastic holding member 1 is a tension spring or an elastic pull rope or an elastic belt. This can make the elastic holding member 1 have a very stable and reliable elastic holding effect, thereby making the roller blind positioning rope elastic structure have very high stability and reliability.

[0022] On the basis of the above structure, the utility model provides three kinds of rolling guide bodies, which are:

[0023] The first one, such as Figure 1 As shown, the rolling guide body 2 is two guide wheels, and the two positioning ropes 3 are respectively wound around the two guide wheels. This can help to play a stable guiding role, thereby helping to improve the reliability of the roller blind positioning rope elastic structure.

[0024] When two guide wheels are used to form the rolling guide body, annular grooves for embedding two positioning ropes 3 are respectively provided on the outer circumferential surfaces of the two guide wheels, which can help improve the stability and reliability of the guidance.

[0025] The second type is that the rolling guide body 2 is a guide wheel, and the two positioning ropes 3 are both wound around the guide wheel. This can reduce the manufacturing difficulty and cost, thereby being conducive to improving the applicability of the roller blind positioning rope elastic structure.

[0026] When a guide wheel is used to form a rolling guide body 2 for two positioning ropes 3 to be wound around, the outer circumferential surface of the guide wheel can be provided with either one annular groove for the two positioning ropes 3 to be embedded in, or two annular grooves for the two positioning ropes 3 to be embedded in respectively, which can help improve the stability and reliability of the guidance.

[0027] The third type is that the rolling guide body 2 is a guide roller, and the two positioning ropes 3 are wound around the guide roller. This can not only ensure the stability of the guide, but also control the manufacturing difficulty and cost, thereby being conducive to improving the reliability and applicability of the roller blind positioning rope elastic structure.

[0028] When a guide roller is used to form a rolling guide body 2 for two positioning ropes 3 to be wound around, the outer circumferential surface of the guide roller can be provided with either one annular groove for the two positioning ropes 3 to be embedded in, or two annular grooves for the two positioning ropes 3 to be embedded in respectively, which can help improve the stability and reliability of the guidance.

[0029] like Figure 3 As shown, the roller blind positioning rope elastic structure further includes a cross bar 4, and two rolling guide bodies 2 are respectively arranged on the left and right ends of the cross bar 4. The cross bar 4 is arranged on the lower end of the roller blind, which can not only be used to strengthen the lower end of the roller blind, but also keep the relative positions of the two rolling guide bodies 2 in a very stable state, thereby helping to further improve the reliability and applicability of the roller blind positioning rope elastic structure.

[0030] like Figures 1 to 3 As shown, the roller blind positioning rope elastic structure further comprises a clamping screw 5, and the other end of the positioning rope 3 is wound or sleeved on the clamping screw 5. This enables the other end of the positioning rope 3 to be clamped and fixed at a corresponding position by using the nut end of the clamping screw 5, which not only improves the convenience of fixing the other end of the positioning rope 3, but also improves the stability of fixing the other end of the positioning rope 3.

[0031] like Figures 1 to 3 As shown, the roller blind positioning rope elastic structure further includes a reinforcing block 6, and the clamping screw 5 is screwed onto the reinforcing block 6. This can enhance the structural strength of the screw connection of the clamping screw 5 through the reinforcing block 6, thereby facilitating the improvement of the stability and reliability of the installation and positioning of the clamping screw 5, and further contributing to the improvement of the reliability of the roller blind positioning rope elastic structure.

[0032] like Figure 2 As shown, guide wheels 7 are arranged on the left and right sides of the elastic holding member 1, and the other ends of the two positioning ropes 3 respectively pass through the two guide wheels 7 and then pass through the corresponding rolling guide bodies 2 downwards. This can guide the positioning ropes 3, thereby improving the stability and reliability of the elastic action and reducing wear.

[0033] The guide wheel 7 is not a necessary component of the roller blind positioning rope elastic structure. In actual use, the guide wheel may not be used, and the positioning rope 3 may be directly overlapped on the relevant component to change the winding direction of the positioning rope 3 through this component, which can also meet the use requirements.

[0034] The positioning rope 3 is a steel wire rope, which can make the positioning rope 3 have high structural strength and durability, thereby helping to further improve the reliability and applicability of the elastic structure of the roller blind positioning rope.

[0035] like Figure 3 and Figure 4 As shown, in the actual installation process, the elastic holding member 1 is arranged in the upper fixed horizontal frame 101 of the rolling curtain device 10, and the left and right ends of the bottom of the fixed horizontal frame 101 are respectively provided with through holes for the two positioning ropes 3 to pass through (not shown in the figure); the cross bar 4 is clamped on the lower end of the rolling curtain 20; the lower ends of the left and right frames 102 of the rolling curtain device 10 are respectively embedded with reinforcement blocks 6, and the two reinforcement blocks 6 are respectively screwed with clamping screws 5, and the two clamping screws 5 respectively clamp the two positioning ropes 3 to the frame 102 or the reinforcement block 6 through the nut ends thereon. In this way, the elastic structure of the rolling curtain positioning rope can be used to play a good limiting role on the rolling curtain 20, so that the tension of the two positioning ropes 3 is kept consistent, which can improve the balance of the rolling curtain moving up and down, and the rolling curtain can be pulled at any point without deviation and displacement, with good synchronization and easy operation, which can solve a lot of troubles for users. Such an elastic structure of the roller shutter positioning rope is very suitable for ship-mounted roller shutters. It can help to stabilize and limit the roller shutter, thereby reducing the vibration caused by wind and ship shaking during ship transportation. This not only helps to reduce the chance of damage to the roller shutter, but also avoids generating loud noise.

[0036] like Figure 4 As shown, a horizontally extending limiting bracket 103 is provided on the lower cavity wall in the fixed transverse frame 101, and the elastic holding member 1 is arranged in the limiting bracket 103, and two through holes respectively penetrate the left and right ends of the limiting bracket 103. This can not only help improve the stability and reliability of the installation and positioning of the elastic holding member 1, but also help the elastic holding member 1 to play a stable and reliable elastic holding role, thereby helping to further improve the reliability of use.

[0037] The above embodiments are preferred embodiments of the present utility model. All structures similar to the present utility model and equivalent changes made thereto should fall within the protection scope of the present utility model.
