Curtain rod with adjustable length

Abstract

The utility model discloses a length-adjustable curtain rod, which relates to the technical field of curtain rods, and comprises a sleeve fixing piece I, sleeve fixing pieces II are arranged at two ends of the sleeve fixing piece I, an inner base rod is arranged at the position of the sleeve fixing piece I, an outer supporting pipe is arranged at the position of the sleeve fixing piece II, and when the length is not enough, the inner base rod is fixed to the outer supporting pipe. The outer supporting pipe can directly slide towards the end away from the first sleeve fixing piece, and when the pipe body slides, the arc-shaped plates close to the first sleeve fixing piece can pop out through the spring rods one by one due to the fact that the arc-shaped plates lose shielding of the pipe body; a complete top surface is formed between the top of the pipe body and the spring rod, so that the distance between the sleeve fixing piece I and the sleeve fixing piece II is increased; secondly, different numbers of arc-shaped plates can be released according to the length needing to be amplified, and the effect that length amplification is selectable is achieved; and finally, the spring rod and the pipe body which are matched in radian also enable the hanging rings on the curtain to slide smoothly, and the situation that the hanging rings are clamped is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of curtain rods, in particular to a curtain rod with adjustable length. Background Art

[0002] Curtain rods are common household items. Many families now use Roman rods. Roman curtain rods are composed of 2-3 fixings and Roman rods. The Roman rod is fixed to the wall by inserting screws on the fixings into the cavity, and then the hanging ring on the curtain is set on the screw.

[0003] In the process of implementing the solution, the inventor found that the following problems in the prior art have not been well solved: users purchase curtain rods of appropriate lengths according to the size of the windows and the size that needs to be blocked, but the lengths of many curtain rods are fixed. After the users purchase them, the movable distance of the curtains on the curtain rods may be too short, resulting in an inability to completely block the sunlight. In this case, it is only necessary to replace the curtain rods with longer ones, but many users purchase online, and it takes a certain amount of time to return or exchange the goods, and they also need to pay a shipping fee. In general, the curtain rod cannot meet the shading requirements of the curtains by adjusting its own length. Utility Model Content

[0004] The main purpose of the utility model is to provide a curtain rod with adjustable length, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A curtain rod with adjustable length comprises a sleeve fixing part 1, sleeve fixing parts 2 are provided at both ends of the sleeve fixing part 1, an inner base rod is provided at the position of the sleeve fixing part 1, an outer support tube is provided at the position of the sleeve fixing part 2, a plurality of inner edge sliders are provided on the inner wall of the sleeve fixing part 2, the inner base rod comprises an intermediate rod, end rods are fixed at both ends of the intermediate rod, a top groove is chiseled at the top of the end of the end of the end of the middle rod, a plurality of spring rods are fixed to the inner bottom end of the top groove, an arc plate is fixed to the end of the spring rod passing through one end of the top groove, special-shaped slide grooves are chiseled on both sides of the end rods away from one end of the top groove, the outer support tube comprises a tube body, a plurality of outer edge slide grooves are chiseled on the outer wall of the tube body, and special-shaped sliders are fixed on both sides of the inner wall of the tube body.

[0007] Preferably, the inner wall of the sleeve fixing member 1 is bonded to the outer wall of the intermediate rod.

[0008] Preferably, the two end rods of the inner base rod are respectively inserted into the tube bodies of the outer support tubes at both ends, and the special-shaped sliding blocks in the tube bodies are respectively inserted into the special-shaped sliding grooves of the end rods and are slidably connected thereto.

[0009] Preferably, the curvature dimension of the outer portion of the arc-shaped plate matches the curvature dimension of the outer portion of the tube body.

[0010] Preferably, the inner sliding blocks of the second sleeve fixing member are respectively inserted into the outer sliding grooves of the tube body and are slidably connected thereto.

[0011] Preferably, one end of the tube body of the two outer support tubes away from the sleeve fixing piece is threadedly connected with a Roman head.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. When the length is not enough, the outer support tube can slide directly to the end away from the sleeve fixing piece 1. When the tube body slides, several arc-shaped plates close to the sleeve fixing piece 1 will be ejected one by one through the spring rod due to the loss of the shielding of the tube body;

[0014] The top of the tube body and the spring rod form a complete top surface, which not only increases the distance between the sleeve fixing member 1 and the sleeve fixing member 2;

[0015] Secondly, different numbers of arc plates can be released according to the required amplified length, so as to achieve the effect of optional length amplification;

[0016] Finally, the matching curvature of the spring rod and tube also allows the hanging rings on the curtains to slide smoothly without getting stuck.

[0017] 2. When the length needs to be shortened, the arc plate is pressed downward to shrink the spring rod until the horizontal height of the top of the arc plate is lower than the horizontal height of the top of the tube body. Then the tube body can slide to the position of one end of the sleeve fixing part, and the shortening length adjustment is also very convenient.

[0018] Therefore, the present application can adjust the distance between the sleeve fixing member 1 and the two sleeve fixing members 2 according to the shading requirements of the curtain, thereby achieving an adjustable effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1-4 As shown, a length-adjustable curtain rod comprises a sleeve fixing member 1, sleeve fixing members 2 are provided at both ends of the sleeve fixing member 1, an inner base rod 3 is provided at the position of the sleeve fixing member 1, an outer support tube 4 is provided at the position of the sleeve fixing member 2, a plurality of inner edge sliders 21 are provided on the inner wall of the sleeve fixing member 2, the inner base rod 3 comprises an intermediate rod 31, end rods 32 are fixed at both ends of the intermediate rod 31, a top groove 33 is chiseled at the top of the end of the end of the end of the end of the intermediate rod 31, a plurality of spring rods 34 are fixed at the inner bottom end of the top groove 33, an arc plate 35 is fixed at the end of the spring rod 34 passing through one end of the top groove 33, special-shaped slide grooves 36 are chiseled on both sides of the end rod 32 away from the end of the top groove 33, the outer support tube 4 comprises a tube body 41, a plurality of outer edge slide grooves 42 are chiseled on the outer wall of the tube body 41, and special-shaped sliders 43 are fixed on both sides of the inner wall of the tube body 41.

[0026] Specifically, the inner wall of the sleeve fixing member 1 is bonded to the outer wall of the intermediate rod 31 to ensure the fixation of the inner base rod 3.

[0027] Specifically, the two end rods 32 of the inner base rod 3 are respectively inserted into the tube body 41 of the outer support tube 4 at both ends, and the special-shaped sliding blocks 43 in the tube body 41 are respectively inserted into the special-shaped sliding grooves 36 of the end rods 32 and slidably connected thereto, so that the inner base rod 3 and the outer support tube 4 can be connected together and slide conveniently during adjustment.

[0028] Specifically, the curvature of the outer portion of the curved plate 35 matches the curvature of the outer portion of the tube body 41 , so that when the hanging ring of the curtain slides on the tube body 41 and the curved plate 35 , it will not get stuck.

[0029] Specifically, the inner sliding blocks 21 of the sleeve fixing member 2 are respectively inserted into the outer sliding grooves 42 of the tube body 41 and slidably connected thereto, so that the sliding during adjustment has more horizontal stability.

[0030] Specifically, one end of the tube body 41 of the two outer support tubes 4 away from the sleeve fixing member 1 is threadedly connected with a Roman head 5.

[0031] Working principle: When the length is not enough, the outer support tube 4 can slide directly to the end away from the sleeve fixing part 1. When the tube body 41 slides, the arc plates 35 close to the sleeve fixing part 1 will be ejected one by one through the spring rod 34 due to the loss of the shielding of the tube body 41.

[0032] The top of the tube body 41 and the spring rod 34 form a complete top surface, which not only increases the distance between the sleeve fixing member 1 and the sleeve fixing member 2;

[0033] Secondly, different numbers of arc plates 35 can be released according to the required amplified length, so as to achieve the effect of optional length amplification;

[0034] Finally, the spring rod 34 and the tube body 41 with matching curvatures also allow the hanging ring on the curtain to slide smoothly without getting stuck. When the length needs to be shortened, the arc plate 35 is pressed downward to shrink the spring rod 34 until the horizontal height of the top of the arc plate 35 is lower than the horizontal height of the top of the tube body 41. Then, the tube body 41 can slide to the position of one end of the sleeve fixing member 1, and the shortening length adjustment is also quite convenient.
