[0002] Curtain rods are a device for supporting and hanging curtains. They are usually made of metal, wood or plastic. You can choose a suitable style according to the curtains and room decoration.

[0003] At present, the existing curtain rod is assembled from a plurality of short rod segments, which are freely spliced ​​together according to the width of the room and the window to form a continuous long rod while maintaining stability. However, the plurality of short rod segments are usually connected front to back through connectors or supporting accessories, and the length of the long rod after splicing is controlled by the number of connections of the short rod segments. The length after splicing cannot be accurately controlled and freely adjusted, and the problem of insufficient length due to less selection of a short rod segment and excessive length due to more selection of a short rod segment is prone to occur. Summary of the invention

[0004] In order to solve the above technical problems, the utility model provides a spliced ​​curtain rod.

[0005] The technical solution of the utility model is as follows: a spliced ​​curtain rod, comprising two movable rods, two connecting rods and a plurality of extension rods located between the two connecting rods, each of the movable rods, each of the connecting rods and each of the extension rods is a tube structure, and also comprises an eccentric wheel lock assembly, the connecting rods and the extension rods are threadedly connected through a connecting device, the movable rods extend into the connecting rods and are movably connected through the eccentric wheel lock assembly;

[0006] The eccentric wheel lock assembly comprises an eccentric wheel lock and an eccentric wheel buckle, wherein the eccentric wheel lock comprises a buckle connection cylinder and an eccentric cylinder, an eccentric is arranged between the eccentric cylinder and the buckle connection cylinder, and the eccentric wheel buckle is rotatably connected to the outside of the eccentric cylinder;

[0007] The buckled cylinder is fixedly connected to the movable rod, and the eccentric cylinder is arranged in the connecting rod.

[0008] By adopting the above technical scheme, the connecting rod and the extension rod are connected to each other as short rod sections to form a long section, and the length of the curtain rod is preliminarily determined. The connecting rods at both ends are provided with a movable rod, and the movable rod extends into the connecting rod to slide, and is movable or fixed by the eccentric wheel lock assembly, so as to realize the adjustment of the length of the overall curtain rod. Furthermore, by cooperating and arranging the eccentric wheel buckle outside the eccentric cylinder, and the eccentric cylinder and the connecting rod are relatively eccentric, so that after the eccentric wheel buckle rotates relative to the eccentric cylinder, the eccentric wheel buckle and the inner wall of the connecting rod are squeezed or relaxed against each other, so as to realize the fixation or movement between the movable rod and the connecting rod.

[0009] The utility model is further configured as follows: the eccentric wheel buckle is a circular ring structure of no less than two-thirds as a whole, the wall thickness of the eccentric wheel buckle gradually increases from one end to the other end, and a plurality of protrusions are arranged on the outer ring wall of the eccentric wheel buckle.

[0010] By adopting the above-mentioned further arrangement, the eccentric wheel buckle can be plugged in and out of the eccentric wheel lock, which is convenient for the installation, removal and replacement of the eccentric wheel buckle. Furthermore, the change in the wall thickness of the eccentric wheel buckle increases the degree of eccentricity during cooperation, so that after the eccentric wheel lock is rotated in the connecting rod, the tension between them is higher, thereby making the friction force greater. The protrusions evenly arranged on the outer ring wall of the eccentric wheel buckle further increase the eccentricity of the eccentric wheel buckle, and at the same time, the roughness of the protrusion surface can be changed, thereby increasing the friction coefficient with the inner wall of the connecting rod, so that the connection between the eccentric wheel lock buckle assembly and the connecting rod is more stable.

[0011] A further configuration of the utility model is that the cross section of the eccentric cylinder presents a "σ"-shaped structure.

[0014] With the above further arrangement, the extension rod and the connecting rod are spliced ​​as short rod ends into a long section, and the length of the curtain rod is preliminarily determined so that the movable rod can be accurately adjusted subsequently to obtain a curtain rod of accurate length.

[0015] The utility model is further configured as follows: a chamfer is provided on one end of the eccentric wheel buckle.

[0016] By adopting the above further arrangement, the eccentric cylindrical part of the eccentric wheel buckle can be smoothly inserted into the connecting rod.

[0031] The technical scheme in this embodiment will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] It should be noted that in the description of the present invention, all directional indications (such as up, down, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0033] In addition, the descriptions of "first", "second", etc. in the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. In the description of the present invention, the meaning of "several" is at least two, such as two, three, etc., unless otherwise clearly and specifically limited.

[0034] like Figure 1-3 As shown, a spliced ​​curtain rod includes movable rods 1 arranged at both ends, each movable rod 1 is connected to a connecting rod 2, and a plurality of extension rods 3 are connected between the two connecting rods 2. The number can be selected according to the required length of the curtain rod. Each movable rod 1, each connecting rod 2 and each extension rod 3 are hollow tube structures.

[0035] One end of each connecting rod 2 and both ends of each extension rod 3 are provided with an internal thread, and the outer surface of the connecting device 4 is provided with an external thread that can match the internal threads of the connecting rod 2 and the extension rod 3. The threaded connection between adjacent extension rods 3 and between the extension rods 3 and the connecting rods 2 is achieved through the connecting device 4.

[0036] Furthermore, the present embodiment also includes an eccentric wheel lock assembly, such as Figure 4-Figure 9 As shown, the eccentric wheel lock assembly can be a plastic part, and the connecting rod 2 and the movable rod 1 are movably connected through the eccentric wheel lock assembly. The outer wall diameter of the movable rod 1 is slightly smaller than the inner wall diameter of the connecting rod 2. The movable rod 1 can be inserted into the connecting rod 2 and slide, and can be moved or fixed through the eccentric wheel lock assembly to adjust the length of the overall curtain rod.

[0037] The eccentric wheel lock assembly includes an eccentric wheel lock 5 and an eccentric wheel buckle 6. The eccentric wheel lock 5 includes a buckling cylinder 9, an eccentric cylinder 7 and circular thin walls located at both ends of the eccentric cylinder 7. The radius of the thin wall is larger than the maximum radius of the eccentric cylinder 7. The buckling cylinder 9 extends into the interior of the movable rod 1 for fixed connection, and the eccentric cylinder 7 at the other end can extend into the interior of the connecting rod 2.

[0038] Furthermore, the cross-section of the eccentric cylinder 7 presents a "σ"-shaped structure, so that the outer surface of the eccentric cylinder 7 is spiral and the distance to the central axis of the buckled cylinder 9 gradually becomes longer, so that the eccentric cylinder 7 is eccentric relative to the buckled cylinder 9, and the eccentric wheel buckle 6 is rotatably connected to the outside of the eccentric cylinder 7, and the circular thin-walled limiters at both ends of the eccentric cylinder 7 prevent the eccentric wheel buckle 6 from sliding out of the range of the eccentric cylinder 7. The eccentric cylinder 7 and the eccentric wheel buckle 6 can be extended into the interior of the connecting rod 2 together. At the same time, the eccentric wheel buckle 6 is a plastic part, which is elastic and can be slightly deformed, and the connection is tighter after squeezing the inner wall of the connecting rod 2.

[0039] Since the eccentric cylinder 7 is relatively eccentric to the connecting rod 2 , after the eccentric wheel buckle 6 rotates relative to the eccentric cylinder 7 , the eccentric wheel buckle 6 and the inner wall of the connecting rod 2 are squeezed or relaxed, thereby achieving fixation or movement between the movable rod 1 and the connecting rod 2 .

[0040] Furthermore, the eccentric wheel buckle 6 has a three-quarter circular ring structure as a whole, so that the eccentric wheel buckle 6 can be plugged in and out of the eccentric wheel lock 5, which is convenient for replacing the eccentric wheel buckle 6 and preventing the eccentric wheel buckle 6 from being worn too much and causing a loose connection with the connecting rod 2. The eccentric wheel buckle 6 is made of plastic material to give it a certain elasticity. The two ends of the eccentric wheel buckle 6 are clamped on the surface of the eccentric cylinder 7 to prevent it from falling off by itself.

[0041] Furthermore, the wall thickness of the eccentric wheel buckle 6 gradually increases from one end to the other end, and a plurality of protrusions are provided on the outer ring wall of the eccentric wheel buckle 6. The gradual change in the wall thickness of the eccentric wheel buckle 6 increases the eccentricity of the eccentric wheel mouth assembly, so that after the eccentric wheel buckle 6 rotates in the connecting rod 2, the tension between them is higher, thereby making the friction force greater, further enhancing the connection strength between the connecting rod 2 and the movable rod 1 to prevent falling. The protrusions evenly arranged on the outer ring wall of the eccentric wheel buckle 6 further increase the eccentricity of the eccentric wheel buckle 6, and at the same time can change the roughness of the protrusion surface, increase the friction coefficient with the inner wall of the connecting rod 2, and make the connection between the eccentric wheel lock assembly and the connecting rod 2 more stable.

[0042] One end of the eccentric wheel buckle 6 that is protruding toward the connecting rod 2 is provided with a chamfer, so that the eccentric cylindrical portion 7 of the eccentric wheel buckle 6 can be smoothly inserted into the connecting rod 2.

[0043] The two movable rods 1 are respectively provided with hook members 8, the hook members 8 are buckled on the movable rods 1, the movable rods 1 are fixed by bolts, and the hook members 8 are fixed to the ceiling or the wall to fix the curtain rod.

[0044] Specifically, according to the required curtain rod length, a corresponding number of extension rods 2 are selected, and each extension rod 2 is connected with a corresponding number of connecting devices 4, and then two connecting rods 2 are selected, and are fixed to the two ends of the extension rod 2 by two connecting devices 4 respectively, and then two movable rods 1 fixed with eccentric wheel lock components are selected, and one end of the two movable rods 1 with the eccentric wheel lock components is inserted into the two connecting rods 2 respectively, and according to the specific length of the required curtain rod, the two movable rods 1 are slid until the overall length is the required length, and then the two movable rods 1 are rotated respectively, so that the eccentric wheel buckle 6 rotates relative to the movable rod 1, as shown in FIG. Figure 10-11 As shown, the thicker part of the eccentric wheel buckle 6 gradually rotates to the convex part with the largest diameter of the eccentric cylinder 7, and the convex part of the eccentric wheel buckle 6 contacts the inner wall of the connecting rod 2 and is continuously squeezed and deformed. Finally, the inner ring of the eccentric wheel buckle 6 tightly clamps the outer surface of the eccentric cylinder 7, and the convex part on the outer ring firmly squeezes the inner wall of the connecting rod 2, so that the eccentric wheel buckle 6 and the inner wall of the connecting rod 2 are occupied by the slightly squeezed and deformed eccentric wheel buckle 6, thereby achieving the fixation of the movable rod 1;

[0045] When it is necessary to adjust the extension distance of the movable rod 1 in the connecting rod 2, the movable rod 1 is rotated in the opposite direction so that the thicker part of the eccentric wheel buckle 6 gradually rotates away from the position with the largest diameter of the eccentric cylinder 7, so that the degree of squeezing between the eccentric wheel buckle 6 and the inner wall of the connecting rod 2 is gradually reduced. Finally, the movable rod 1 can move relative to the connecting rod 2, and then move again to the required length, and rotate the movable rod 1 to complete the locking. Finally, the two hooks 8 are symmetrically placed on the curtain rod, which can be on the movable rod 1 or the connecting rod 2. Finally, the hooks 8 are fixed to the ceiling or wall to fix the curtain rod.

[0046] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that technical personnel in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
