Description

Technical Field

[0001] This utility model relates to the field of curtain structure technology, and in particular to a fixed-distance structure for serpentine curtains. Background Technology

[0002] Snake-shaped curtains are a common type of bed curtain. Currently, the fixed distance of snake-shaped curtains is mainly achieved by fixed distance ropes on the hanging wheels. The existing fixed distance ropes are evenly equipped with multiple positioning pieces. When in use, the positioning pieces are fixed on the top surface of the corresponding hanging wheels. Each positioning piece corresponds to one hanging wheel. After installing the fixed distance rope on the hanging wheel, the hanging wheel is installed on the track, and then the curtain fabric is installed on the hanging wheel. This installation method uses more hanging wheels on the track. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a paper-wrapped wire winding reel to solve the aforementioned technical problems.

[0004] The technical solution of this utility model is as follows: A fixed-distance structure for a serpentine curtain includes a fixed-distance rope and multiple positioning elements disposed on the fixed-distance rope. The multiple positioning elements are arranged in groups, and the distance between adjacent groups of positioning elements is equal. The distance between two adjacent positioning elements in each group is equal. The distance between adjacent groups of positioning elements is greater than the distance between two adjacent positioning elements in each group.

[0005] Optionally, the positioning element is a ball.

[0006] Optionally, the bead is integrally formed with or fixedly connected to the fixed-distance rope.

[0007] Optionally, the positioning element is a cylinder.

[0008] Optionally, the cylinder is integrally formed with or fixedly connected to the fixed-distance rope.

[0009] Optionally, it may also include a caster wheel connected to the positioning element.

[0010] The fixed-distance structure provided by this utility model, compared with the arrangement of multiple positioning components evenly arranged on a fixed-distance rope, groups the positioning components and sets the distance between adjacent groups of positioning components to be greater than the distance between two adjacent positioning components in each group. The distance between two positioning components in each group is equal to the distance between two adjacent positioning components when multiple positioning components are evenly arranged on a fixed-distance rope. Therefore, the use of positioning components can be reduced on a fixed-distance rope of the same length. Attached Figure Description

Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0013] Example 1, referring to Figure 1 This embodiment is a fixed-distance structure for a serpentine curtain, including a fixed-distance rope 30 and multiple positioning elements disposed on the fixed-distance rope. In this embodiment, the positioning element is a bead 30-1, which is integrally disposed with or fixedly connected to the fixed-distance rope; the multiple positioning elements are arranged in groups, and the distance S between adjacent groups of positioning elements is equal; the distance L between two adjacent positioning elements in each group is equal; the distance between adjacent groups of positioning elements is greater than the distance between two adjacent positioning elements in each group.

[0014] The aforementioned serpentine curtain uses a fixed-distance structure relative to the arrangement of multiple positioning components evenly placed on a fixed-distance rope. The positioning components are grouped and the distance between adjacent groups of positioning components is set to be greater than the distance between two adjacent positioning components in each group. The distance between two positioning components in each group is equal to the distance between two adjacent positioning components when multiple positioning components are evenly placed on a fixed-distance rope. Therefore, the number of positioning components used on a fixed-distance rope of the same length can be reduced.

[0015] Generally, two positioning pieces are sufficient in each group. After the curtain fabric is installed, the two positioning pieces bear the tension of the curtain near the corresponding set of fixing pieces, which can meet the fixing requirements of the curtain.

[0016] As one implementation method, see Figure 3The spacing structure also includes a caster 40 connected to the positioning element. The caster can be connected to the positioning element in an existing manner. As one embodiment, see [link to embodiment]. Figure 4 and Figure 5 The hanging wheel includes a hanging wheel body 40-1 and a roller 40-2 mounted on the hanging wheel body. In this embodiment, the top surface of the hanging wheel body is preferably provided with a positioning groove 40-3 for locking the positioning component. During manufacturing, in the fixed state, the top surface of the positioning component is located below or flush with the top surface of the positioning groove. This ensures that the top surface of the fixing component will not be higher than the top surface of the hanging wheel. During the process of installing the hanging wheel with a fixed-distance rope and then installing the hanging wheel on the track, the top surface of the fixing component will not abut against the top surface of the track, thereby facilitating the hanging wheel's movement on the track. Sliding; In actual manufacturing, grooves 40-4 for accommodating the positioning rope can also be provided on both sides of the positioning groove. The grooves are connected to the positioning groove. By setting the grooves 40-4, after the positioning component is squeezed into the positioning groove, the portion of the distance rope corresponding to the groove position enters the groove, thereby preventing the distance rope from being damaged by friction on the top surface of the roller and the top surface of the track. In addition, the grooves on both sides of the positioning groove restrict the distance rope, making it less likely for the distance rope to deviate and contact the track during the stretching and contraction process, preventing the distance rope from being stuck on the track. In manufacturing, the top surface of the roller body can be made into an arc shape on both sides of the roller. In this way, the grooves 40-4 can be set near the positioning groove to achieve the above functions. It is not necessary to extend the end of the groove that is not connected to the positioning groove through the entire top surface of the roller body. Of course, in actual manufacturing, the end of the groove that is not connected to the positioning groove can extend through the entire top surface of the roller body as needed.

[0017] Example 2, refer to Figure 2 The structure of Embodiment 2 is roughly the same as that of Embodiment 1, except that the positioning element is a cylinder 30-2, wherein the cylinder is integrally formed or fixedly connected with the fixed-distance rope.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
