[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] like Figures 1-10As shown, an adjustable and easy-to-install curtain rod includes a main curtain rod 1 and two extension rods 2 connected to opposite ends of the main curtain rod 1. The extension rods 2 are located on the extension line of the main curtain rod 1 along its length. The ends of the extension rods 2 have external thread structures 21, and the main curtain rod 1 has internal thread structures 11 that are adapted to the external thread structures 21. A clamping member 3 that moves synchronously with the extension rods 2 is sleeved on the extension rods 2, and an adjusting sleeve 4 connected to the extension rods 2 is sleeved at the end of the clamping member 3.

[0031] The main curtain rod 1 and the extension rods 2 connected to both ends of the main curtain rod 1 form an integral curtain rod structure. Under the action of the internal thread structure 11 and the external thread structure 21, the extension rods 2 and the main curtain rod 1 are threadedly connected. Under the action of the threaded connection, the feed amount of the end of the extension rod 2 in the main curtain rod 1 is controlled, so that the extension rod 2 can move along the axial direction of the main curtain rod 1, thereby adjusting the overall length of the main curtain rod 1 and the extension rod 2. During the movement of the extension rod 2 along the axial direction of the main curtain rod 1, the clamping parts 3 are simultaneously driven to move along the axial direction of the main curtain rod 1, thereby adjusting the distance between the two clamping parts 3 on the two extension rods 2.

[0032] Two extension rods 2 are located on the extension lines at both ends of the main curtain rod 1, and both extension rods 2 are threadedly connected to the main curtain rod 1. Each extension rod 2 is fitted with a corresponding clamping component 3 and an adjusting sleeve 4. The two extension rods 2 are independently set at both ends of the main curtain rod 1, and as the extension rods 2 move along the axial direction of the main curtain rod 1, they synchronously drive the corresponding clamping components 3 to move synchronously, thereby controlling the distance between the two clamping components 3.

[0033] The clamping component 3 includes a sleeve 31, a connecting arm 32, and a clamping plate 33 connected in sequence. The sleeve 31 is sleeved on the end of the extension rod 2, and the end of the sleeve 31 forms an abutment ring 36 that abuts against the extension rod 2. The clamping plate 33 is clamped on the wall, so that the overall structure can be installed between the two walls under the simultaneous clamping action of the two clamping components 33.

[0034] A through hole 37 is formed in the middle of the abutment ring 36, and a connector 23 is formed at the end of the extension rod 2, which passes through the through hole 37 and connects to the adjusting sleeve 4. The size of the connector 23 is smaller than that of the through hole 37. Under the action of the through hole 37, the connector 23 can pass through the through hole and connect to the adjusting sleeve 4, so as to realize the linkage between the extension rod 2 and the adjusting sleeve 4.

[0035] The extension rod 2 has an abutment piece 21 at its end that abuts against the abutment ring 36. The connector 23 is formed on the abutment piece 21. Under the action of the abutment piece 21 abutting against the abutment ring 36, the extension rod 2 moves synchronously along the axial direction of the curtain rod 1, thereby driving the pressing member 3 to move synchronously.

[0036] The adjusting sleeve 4 rotates coaxially with the extension rod 2. The clamping member 3 is loosely fitted at the end of the extension rod 2, and the adjusting sleeve 4 is loosely fitted at the end of the clamping member 3. A snap-fit ​​groove 24 is formed on the connector 23 along the length direction of the connector 23, and a snap-fit ​​protrusion 41 is formed inside the adjusting sleeve 4 to snap-fit ​​with the snap-fit ​​groove 24.

[0037] Under the action of the snap-fit ​​groove 24 and the snap-fit ​​protrusion 41, the connector 23 is snapped in the adjusting sleeve 4, so that the rotation of the adjusting sleeve 4 can synchronously drive the rotation of the connector 23, and then drive the rotation of the extension rod 2, thereby realizing the adjustment of the overall length of the extension rod 2 and the curtain main rod 1.

[0038] The clamping plate 33 has a positioning hole 35 for mounting the clamping plate 33, and the connecting arm 32 has a buffer groove 34 for buffering the deformation of the connecting arm 32 under force.

[0039] Screws can be installed in the positioning hole 55 to fix the clamping plate 33 to the wall, further improving the overall support strength of the curtain rod.

[0040] The sleeve 31, connecting arm 32 and clamping plate 33 are an integral structure.

[0041] The surface of the adjusting sleeve 4 is formed with a rubber sleeve 42 that facilitates the rotation of the adjusting sleeve 4.

[0042] In actual use, the curtain body 1, extension rod 2, clamping parts 3, and adjusting sleeve 4 are assembled. The distance between the two clamping parts 3 is adjusted according to the distance between the two opposing walls. When one clamping part 3 abuts against the wall surface, the adjusting sleeve 4 or extension rod 2 is rotated to move the extension rod 2 along the length of the curtain main rod 1, thereby driving the other clamping part 3 to move until the other clamping part 3 also abuts against the wall surface on the other side. Then, the adjusting sleeve 4 or extension rod 2 is rotated to strengthen the abutment strength between the two clamping parts 3 and the corresponding walls. Screws are then driven into the clamping parts 3 as needed.

[0043] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0044] Although this document uses numerous reference numerals from the accompanying drawings—including: curtain rod 1, internal thread structure 11, extension rod 2, external thread structure 21, abutment piece 22, connector 23, snap-fit ​​groove 24, clamping piece 3, sleeve 31, connecting arm 32, clamping plate 33, buffer groove 34, positioning hole 35, abutment ring 36, through hole 37, adjusting sleeve 4, snap-fit ​​protrusion 41, and rubber sleeve 42—the possibility of using other terms is not excluded.
