[0002] The shower curtain rod is a supporting rod used to hang the shower curtain in the bathroom. It is simple to use, cheap and easy to replace. Generally, the shower curtain rod is an inner and outer tube structure, that is, a small tube (inner tube) extends into a large tube (outer tube), and then the shower curtain is hung by using an inner buckle, spring or screw to fix the shower curtain rod. Ordinary shower curtain rods usually cannot be adjusted in length and have poor applicability. Some shower curtain rods with adjustable fixed length have problems such as insufficient support and unreliable fixation at both ends.

[0003] The patent application document with application number 202322611140.X discloses a length-adjustable shower curtain, wherein the hanging rod includes a first connecting rod, a second connecting rod and a connecting piece, the first connecting rod is provided with a sliding hole, the second connecting rod is slidably inserted in the sliding hole, the connecting piece includes a compression spring, the compression spring is slidably inserted in the sliding hole, the adjusting piece includes a connecting column, a connecting spring and a buckle, the connecting column is arranged on the second connecting rod, the connecting column is provided with a mounting hole, the buckle is slidably installed in the mounting hole, the connecting spring is arranged between the buckle and the bottom of the mounting hole, the first connecting rod is provided with a plurality of slots for the buckle to be inserted into the side wall of the sliding hole, and the slots are evenly spaced along the length direction of the first connecting rod. Although this type of hanging rod can adjust the length and increase the supporting force by axially pressing with a spring, when the second connecting rod moves in the sliding hole of the first connecting rod, the adjusting piece is only driven to move by the spring, and the stability of the spring connection is poor. The adjusting piece is easy to slide along the circumference of the sliding hole and staggered with the slot, which is not convenient for engagement and positioning.

[0026] The following further elaborates on the specific embodiments of the present utility model with reference to the drawings.

[0027] Embodiment 1:

[0028] A telescopic shower rod provided in this embodiment, such asFigures 1-5 As shown in Figures 1-5 , it includes a main rod body, which consists of a first rod 1, a second rod 2 and an adjusting support mechanism. One end of the first rod 1 extends into the second rod 2 and is adjustably connected through the adjusting support mechanism. The adjusting support structure is connected to one end of the first rod 1 and extends into the second rod 2 through the adjusting support structure to be adjustably connected to the second rod 2. The adjusting support mechanism is used to adjust the telescopic length of the main rod body formed by the connection of the first rod 1 and the second rod 2.

[0029] Both the above-mentioned first rod 1 and second rod 2 are of circular tube structure, which facilitates the hook hanging on it to slide along the length direction of the main rod body. The outer diameter of the first rod 1 is equal to the inner diameter of the second rod 2. The first rod 1 and the second rod 2 can be made of plastic or metal materials. Preferably, both the first rod 1 and the second rod 2 are made of stainless steel material, which has good support strength.

[0030] The adjusting support structure includes a connection seat 6, a connecting rod 5, an elastic member 7 and a locking head 4. One end of the connecting rod 5 is connected to the locking head 4. The locking head is fixedly connected to the connecting rod. The connection seat 6 is slidably connected to the connecting rod 5 along the length direction of the connecting rod 5 and is circumferentially limited on the connecting rod 5. The connection seat 6 is circumferentially limited relative to the connecting rod 5, that is, the connection seat 6 cannot rotate on the connecting rod 5.

[0031] The elastic member 7 is sleeved on the connecting rod 5 and its two ends are respectively connected to the connection seat 6 and the locking head 4. Among them, the elastic member 7 can be a telescopic spring. The elastic member 7 has a tendency to make the connection seat 6 slide on the connecting rod 5 towards the end away from the locking head 4.

[0032] One end of the first rod 1 is connected to the connection seat 6, and the first rod 1 is fixedly connected to the connection seat 6. The locking head 4 extends into the second rod 2 and is adjustably connected to the second rod 2. The locking head and the connecting rod

[0033] When the telescopic shower rod of this embodiment is in use, according to the need, the length of the first rod 1 extending into the second rod 2 is adjusted. During the process of the first rod 1 extending into the second rod 2, the connection seat 6 drives the locking head 4 to move together with the first rod 1 in the second rod 2 through the connecting rod 5. During the movement, the connection seat 6 cannot rotate on the connecting rod 5 and one end of the connecting rod 5 is connected to the locking head 4. Therefore, the locking head 4 cannot rotate relative to the first rod 1 during the movement. When the first rod 1 moves to the required position relative to the second rod 2, rotating the first rod 1 can drive the locking head 4 to rotate synchronously through the connecting rod 5 to lock the locking head 4 in the second rod 2 for positioning, so that the length of the main rod body can be adjusted arbitrarily within a certain range.

[0034] In this embodiment, the first rod body 1 of the telescopic shower rod is fixedly connected to the connecting seat 6. The connecting seat 6 is connected to the locking head 4 through the connecting rod 5 and the elastic member. The connecting rod provides guiding support for the contraction of the elastic member, and the connection is highly stable, enabling the first rod body 1 to drive the locking head 4 to rotate synchronously. Additionally, by providing the elastic member 7, the elastic member has an axial thrust on the connecting seat 6 towards one end of the first rod body 1, pressing the opposite ends of the first rod body 1 and the second rod body 2 against the wall surface, making the fixation more secure and the shower rod having better support strength.

[0035] As a preferred embodiment, the longitudinal cross-section of the connecting rod 5 is polygonal. The longitudinal cross-section of the connecting rod 5 can be triangular, quadrilateral, pentagonal or hexagonal. The connecting portion of the connecting seat 6 and the connecting rod 5 has a mating connecting hole. When the connecting rod penetrates into the connecting hole for connection, the rotation of the connecting seat 6 can drive the connecting rod and the locking head to rotate synchronously.

[0036] As a preferred embodiment, as Figure 5 shown, the longitudinal cross-section of the connecting rod 5 is in the shape of an 'H'. The connecting rod 5 can limit the rotation of the connecting seat 6, and it is light in weight and high in support strength.

[0037] It should be noted that the longitudinal cross-section of the connecting rod 5 can also be other shapes, as long as it can limit the rotation of the connecting seat 6.

[0038] As a preferred embodiment, as Figures 2-4 shown, one end of the locking head 4 has a first connecting portion 41. A connecting head 51 is provided at one end of the connecting rod 5, and the connecting head 51 can be cylindrical or rectangular. A connecting cavity 411 adapted to the connecting head 51 is provided in the first connecting portion 41. The connecting head 51 extends into the connecting cavity 411 and is connected through a connecting member passing through the first connecting portion 41 and the connecting rod 5.

[0039] Specifically, the connecting head 51 has a through hole 511 perpendicular to the length direction of the connecting rod 5. The connecting member passes through the through hole 511 and the side wall of the first connecting portion 41, thereby fixedly connecting the locking head 4 and the connecting rod 5.

[0040] As a preferred embodiment, as Figure 4 shown, the connecting seat 6 includes a second connecting portion 61. A connecting hole 611 adapted to the connecting rod 5 is provided in the second connecting portion 61. A baffle 52 is provided at the end of the connecting rod 5 far from the locking head 4, and the diameter of the baffle 52 is greater than the width of the connecting rod 5. The connecting rod 5 passes through the connecting hole 611 and the baffle 52 is located outside the connecting hole 611 at the end far from the locking head 4. The baffle 52 can prevent the connecting seat 6 from slipping off the connecting rod 5.

[0041] As a preferred embodiment, as Figure 4As shown, one end of the locking head 4 away from the first connecting portion 41 has a frustum 42. A first retaining ring 43 is provided along the outer periphery between the frustum 42 and the first connecting portion 41. One end of the connecting seat 6 away from the second connecting portion 61 has a third connecting portion 62 connected to the first rod body 1. The third connecting portion 62 is press-fitted into the first rod body 1.

[0042] A second retaining ring 63 is provided along the outer periphery between the second connecting portion 61 and the third connecting portion 62. One end of the elastic member 7 abuts against the first retaining ring 43 and the other end abuts against the second retaining ring 63, thereby connecting the elastic member between the locking head 4 and the connecting seat 6. Preferably, the outer parts of the first connecting portion and the second connecting portion are both cylindrical.

[0043] In addition, both ends of the elastic member 7 can also be connected to the locking head 4 and the connecting seat 6 by screws. The above-mentioned screws are vertically fixed on the tube walls of the first connecting portion and the second connecting portion, and both ends of the elastic member 7 are respectively hooked on the two screws.

[0044] As a preferred embodiment, a sliding cavity is provided in the third connecting portion 62. The sliding cavity 621 is cylindrical, and the baffle 52 is also circular. The diameter of the sliding cavity 621 is larger than the diameter of the connecting hole 611, and the baffle 52 is slidably arranged in the sliding cavity 621.

[0045] As a preferred embodiment, as Figure 1 shown, the adjusting and supporting structure further includes an expansion tube 8. The inner hole of the expansion tube 8 is a tapered hole, and the tapered hole is provided with internal tapered threads. External tapered threads are provided on the outside of the frustum 42. The frustum 42 is screwed into the expansion tube 8 through the cooperation of the external tapered threads and the internal tapered threads.

[0046] During use, when the first rod body 1 is adjusted to the required position, rotate the first rod body 1, and then drive the connecting seat 6 and the locking head 4 to rotate synchronously, so that the external tapered threads on the frustum 42 are gradually screwed tightly with the internal tapered threads on the expansion tube 8, and the expansion tube 8 is gradually expanded by the frustum 42 and radially abuts against the inner wall of the second rod body 2, so that the position of the first rod body 1 is fixed and will not axially expand and contract.

[0047] The telescopic shower rod of this embodiment further includes a limit sleeve 9. The limit sleeve 9 is fixed at one end of the second rod body 2 connected to the first rod body 1 and is movably sleeved outside the first rod body 1. The outer diameter of the second retaining ring 63 on the outer wall of the connecting seat 6 is larger than the inner diameter of the limit sleeve 9. The above-mentioned limit sleeve 9 is used to limit the maximum extendable distance of the first rod body and prevent the first rod body from coming out of the second rod body.

[0048] As a preferred embodiment, a retaining platform 44 is provided at the end of the frustum 42, and the outer diameter of the retaining platform 44 is larger than the inner diameter of the small-diameter end of the tapered hole. Thus, the above expansion tube 8 is always sleeved outside the frustum 42 of the locking head 4. When the first rod body is moved, the frustum 42 always drives the expansion tube 8 to move simultaneously, and the frustum 42 will not separate from the expansion tube 8.

[0049] As a preferred embodiment, the telescopic shower rod of this embodiment further includes a head 3 for pressing against the wall. The number of the heads 3 is two, and the two heads 3 respectively cover the opposite ends of the first rod body 1 and the second rod body 2. The head 3 increases the contact area with the wall and protects the wall from damage. Preferably, a groove is provided on the outer side surface of the head 3, and an anti-slip gasket is provided in the groove. The anti-slip gasket increases the friction with the wall and prevents the two ends of the shower curtain rod from slipping on the wall.

[0050] When the telescopic shower rod of this embodiment is in use, if the distance between two walls is 100 cm, adjust the position of the first rod body in the second rod body to make the total length of the shower curtain rod reach 105 cm. Then rotate the first rod body to drive the locking head 4 to rotate synchronously, so that the expansion tube 8 supports the inner wall of the second rod body to fix the position of the first rod body. At this time, just press the first rod body towards the second rod body side to make the first rod body retract into the second rod body by 16 to 7 cm, so that the elastic member 7 is compressed to store energy. Then place the shower curtain rod between the two walls and release the first rod body. The above elastic member 7 restores its deformation, thereby pushing the ends of the first rod body and the second rod body to tightly support the wall, so that the shower curtain rod is firmly fixed between the two walls.

[0051] The above is only the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can make several deformations and improvements without departing from the creative concept of the present invention, and all should be covered within the protection scope of the present invention.
