As shown in fig. 1 to 4, some embodiments of the present utility model provide a telescopic rod, which is mainly applied to a rail or a gate, to promote quick adjustment of the telescopic rod.

The telescopic rod includes a first pull rod 100, an eccentric shaft 200, an eccentric sleeve 500, and a second pull rod 300.

In the first direction, the first tie rod 100 defines a guide channel 110, i.e. the axis of the guide channel 110 is parallel to the first direction. Wherein one end of the first tie rod 100 is opened, which communicates with one end of the guide passage 110.

The first direction refers to the axial direction of the first tie rod 100.

Eccentric shaft 200 is slidably disposed in guide channel 110, and it is understood that eccentric shaft 200 is capable of sliding in a first direction in guide channel 110.

Wherein, the periphery of the eccentric shaft 200 is provided with a first connecting ring 210 and a second connecting ring 220 which are spaced apart, and the eccentric sleeve 500 is rotatably sleeved on the eccentric shaft 200, and the eccentric sleeve 500 is arranged between the first connecting ring 210 and the second connecting ring 220, so that the eccentric sleeve 500 is limited by the first connecting ring 210 and the second connecting ring 220, thereby preventing the eccentric sleeve 500 from falling off from the eccentric shaft 200 and ensuring the stability of the eccentric sleeve 500 on the eccentric shaft 200.

In addition, one end of the second pull rod 300 is disposed in the guide channel 110 and fixedly connected with the eccentric shaft 200, and the other end of the second pull rod 300 is located outside the guide channel 110, and the second pull rod 300 is slidably connected with the first pull rod 100, i.e. the first pull rod 100 is slidably sleeved on the second pull rod 300. It will be appreciated that the length of the telescoping rod is adjusted by positioning a portion of the second rod 300 outside the guide channel 110 such that a worker can grasp an end of the second rod 300 that is remote from the first rod 100 and pull the first rod 100 and the second rod 300 in a first direction to adjust the overlapping portion between the first rod 100 and the second rod 300.

In the present embodiment, the connection between the second pull rod 300 and the eccentric shaft 200 is a rivet connection.

In the present embodiment, the axis of the first tie rod 100 coincides with the axis of the second tie rod 300.

Since the eccentric shaft 200 is fixedly connected with the second tie rod 300 and the eccentric shaft 200 is slidably connected with the first tie rod 100, when the second tie rod 300 moves in the first direction with respect to the first tie rod 100, at this time, the eccentric shaft 200 moves in synchronization with the second tie rod 300.

Specifically, after the second tie rod 300 is rotated by a preset angle in the second direction with respect to the first tie rod 100, the distance between the axis of the eccentric shaft 200 and the axis of the eccentric sleeve 500 is gradually increased such that the sidewall of the eccentric sleeve 500 is gradually close to the inner wall of the guide passage 110.

As shown in fig. 8, the axis of eccentric shaft 200 in the present application refers to the central axis of eccentric shaft 200, that is, the axis corresponding to the outer diameter of eccentric shaft 200. It will be appreciated that the axis corresponding to the outer diameter of eccentric shaft 200 does not coincide with the axis corresponding to the inner diameter of eccentric shaft 200.

As shown in fig. 10, the axis of the eccentric sleeve 500 according to the present application is an axis corresponding to the outer diameter of the eccentric sleeve. It will be appreciated that the axis corresponding to the outer diameter of the eccentric sleeve 500 does not coincide with the axis corresponding to the inner diameter of the eccentric sleeve 500.

When the sidewalls of the eccentric sleeve 500, the first connection ring 210 and the second connection ring 220 are respectively abutted against the inner wall of the guide channel 110, the friction force between the eccentric shaft 200, the first connection ring 210 and the second connection ring 220 and the inner wall of the guide channel 110 is increased, so that the resistance between the eccentric shaft 200 and the eccentric sleeve 500 and the first pull rod 100 is increased, the eccentric shaft 200 and the eccentric sleeve 500 are in a tensioned state, a limit structure is formed between the eccentric shaft 200 and the eccentric sleeve 500 and the first pull rod 100, the first pull rod 100 and the second pull rod 300 are fixed through the eccentric shaft 200 and the eccentric sleeve 500, the first pull rod 100 and the second pull rod 300 are prevented from sliding relatively along the first direction, the locking purpose is achieved, and the tightness and the stability of the telescopic rod are improved.

When the second tie rod 300 is rotated in the third direction by a preset angle with respect to the first tie rod 100, the distance between the axis of the eccentric shaft 200 and the axis of the eccentric sleeve 500 is gradually reduced, i.e., the friction between the sidewalls of the eccentric shaft 200, the first connection ring 210 and the second connection ring 220 and the inner wall of the guide passage 110, respectively, is gradually reduced. When a gap is formed between the side wall of the eccentric sleeve 500 and the side wall of the guide passage 110, that is, the friction force between the outer wall of the eccentric shaft 200 and the inner wall of the guide passage 110 is reduced or zero, so that the eccentric shaft 200 can slide in the guide passage 110. That is, the first tie rod 100 can slide in the first direction with respect to the second tie rod 300, that is, at this time, the telescopic rod can be extended or contracted, thereby adjusting the length of the telescopic rod to meet the user's demand for the length of the telescopic rod.

It should be noted that the second direction is opposite to the third direction, and both the second direction and the third direction are perpendicular to the first direction.

Specifically, in the present embodiment, if the second direction is a counterclockwise direction, the third direction is a clockwise direction; if the second direction is counterclockwise, the third direction is clockwise.

By rotating the second drawbar 300 in the third direction, a gap is formed between the eccentric sleeve 500 and the inner wall of the guide channel 110, so that the first drawbar 100 and the second drawbar 300 can relatively move in the first direction to adjust the length of the telescopic rod, thereby satisfying different demands of users. The second tie rod 300 is rotated in the second direction to increase the distance between the axis of the eccentric shaft 200 and the axis of the eccentric sleeve 500, so that the first tie rod 100 and the second tie rod 300 are locked through the eccentric shaft 200 and the eccentric sleeve 500 to improve the stability of the telescopic rod, and the locking efficiency and the locking convenience between the first tie rod 100 and the second tie rod 300 are improved.

As shown in fig. 8 to 10, in some embodiments of the present utility model, the eccentric sleeve 500 is provided with a notch 510, and it should be noted that, along the first direction, the length of the notch 510 is equal to the thickness of the eccentric sleeve 500, so that the notch 510 cuts off the eccentric sleeve 500 to form a "C" -shaped notch 510 ring.

By providing the notch 510 on the eccentric sleeve 500 to define the first section 520 and the second section 530 on the eccentric sleeve 500, it is understood that the notch 510 is located between the first section 520 and the second section 530, and the first section 520 is disposed opposite the second section 530.

It should be noted that, when the second pull rod 300 rotates in the second direction relative to the first pull rod 100, the sides of the first section 520 and the second section 530, which are close to the eccentric shaft 200, can abut against the side wall of the eccentric shaft 200, i.e., the side wall of the eccentric shaft 200 forms an abutting force against the side of the eccentric sleeve 500, which is close to the notch 510, so that the portion of the eccentric sleeve 500, which is close to the notch 510, is spread by the eccentric shaft 200, such that the distance between the first section 520 and the second section 530 increases, and thus the outer diameter of the eccentric sleeve 500 increases.

It can be appreciated that by providing the notch 510 on the eccentric sleeve 500, not only can the distance between the axis of the eccentric sleeve 500 and the axis of the eccentric shaft 200 be increased, but also the sidewall of the eccentric shaft 200 can form an interference force on the side of the eccentric sleeve 500 near the notch 510, and the distance between the first section 520 and the second section 530 can be increased, thereby increasing the outer diameter of the eccentric sleeve 500, so as to further increase the frictional resistance between the sidewall of the eccentric sleeve 500 and the inner wall of the guide channel 110, thereby improving the locking quality between the eccentric sleeve 500, the eccentric shaft 200 and the first tie rod 100, and thus improving the locking quality and stability between the first tie rod 100 and the second tie rod 300, in the process of rotating the eccentric shaft 200 in the second direction with respect to the eccentric sleeve 500.

As shown in fig. 2, in some embodiments of the present utility model, a relief space 540 is provided on a side of the eccentric sleeve 500 facing the second connecting ring 220, and the relief space 540 is in a fan-shaped structure along the projection of the first direction.

In this embodiment, the relief space 540 communicates with the notch 510 to define a third section 550 at an end of the eccentric sleeve 500 remote from the first section 520. Further, the included angle between the first section 520 and the third section 550 is smaller than the corresponding arc angles of the first section 520 and the third section 550 on the eccentric sleeve 500, so that when the second pull rod rotates along the second direction relative to the first pull rod, a part of the first section 520, which is close to the eccentric shaft 200, can abut against the eccentric shaft 200 to form a limit, and when the stop block 230 abuts against the third section 550, the eccentric sleeve 500 rotates along with the eccentric shaft 200 along the second direction.

Specifically, a stop 230 is disposed on a side of the first connection ring 210 facing the second connection ring 220, and the stop 230 is at least partially located in the yielding space 540, so as to limit the eccentric sleeve 500 through the stop 230, so as to define a rotation angle of the eccentric sleeve 500.

During the relative rotation of the eccentric shaft 200 and the eccentric sleeve 500, the stopper 230 can be limited by the first and third sections 520 and 550 to define the rotation angle of the stopper 230, thereby defining the rotation angle of the eccentric shaft 200 with respect to the eccentric sleeve 500.

When the eccentric shaft 200 rotates a predetermined angle along the second direction, the stop 230 abuts against the third section 550, so as to limit the stop 230 through the third section 550.

That is, when the eccentric shaft 200 rotates in the second direction, the stop block 230 is driven by the eccentric shaft 200 to rotate synchronously, and when the stop block 230 abuts against the third section 550, the stop block has a tendency to rotate in the second direction under the action of the stop block 230. Meanwhile, one side of the inner wall of the eccentric sleeve 500, which is close to the first section 520, is abutted against the side wall of the eccentric shaft 200, and forms a limit for the eccentric sleeve 500, that is, forms a resistance for the eccentric sleeve 500, thereby preventing the eccentric sleeve 500 from rotating in the second direction under the action of the stop block 230.

Further, when the stopper 230 continues to rotate in the second direction, since the stopper 230 presses the third section 550 and the side of the inner wall of the eccentric sleeve 500 near the first section 520 abuts against the eccentric shaft 200, the end of the eccentric sleeve 500 near the first section 520 is stationary relative to the first tube 130, and the third section 550 moves away from the first section 520 under the pressure of the stopper 230. At the same time, the distance between the first section 520 and the second section 530 is gradually increased, that is, the gap 510 is gradually increased, so that the outer diameter of the eccentric sleeve 500 is gradually increased, that is, the friction between the outer wall of the eccentric sleeve 500 and the inner wall of the guide passage 110 is increased, that is, the resistance to movement between the eccentric sleeve 500 and the first pull rod 100 is increased, to prevent the eccentric shaft 200 from sliding in the guide passage 110 in the first direction, thereby fixedly locking the eccentric sleeve 500 and the first pull rod 100. Because the second pull rod 300 is fixedly connected with the eccentric shaft 200, when the eccentric sleeve 500 is fixedly locked with the first pull rod 100, the second pull rod 300 is fixedly locked relative to the first pull rod 100 so as to fix the relative position between the first pull rod 100 and the second pull rod 300, and the first pull rod 100 is prevented from moving relative to the second pull rod 300 along the first direction, so that the stability of the length of the telescopic rod is ensured.

In addition, when the stopper 230 abuts against the first section 520 during the movement of the stopper 230 along the third direction, the first section 520 tends to move away from the eccentric shaft 200 under the action of the stopper 230, so that the acting force between the side of the inner wall of the eccentric sleeve 500, which is close to the first section 520, and the side wall of the eccentric shaft 200 is gradually reduced, and the friction between the end of the eccentric sleeve 500, which is close to the third section 550, and the inner wall of the guide channel 110 is reduced, so that the third section 550 tends to move towards the direction close to the first section 520.

Because the gap is formed between the end of the stopper, which is close to the first section 520, and the inner wall of the guide channel 110, when the acting force between the eccentric shaft 200 and the side of the inner wall of the eccentric sleeve 500, which is close to the first section 520, is smaller than the preset value, the friction force between the third section 550 and the inner wall of the guide channel 110 is zero, and at this time, the third section 550 is close to the first section 520, so that the eccentric sleeve 500 is restored to the initial state, and the outer diameter of the eccentric sleeve 500 is restored to the initial state. It will be appreciated that at this time, there is a gap between the eccentric shaft 200 and the inner wall of the guide passage 110, i.e., the eccentric shaft 200 can move in the guide passage 110 in the first direction, so that the first tie rod 100 can move in the first direction with respect to the second tie rod 300, thereby adjusting the length of the telescopic rod to meet the user's needs.

As shown in fig. 2, 4 and 7, in some embodiments of the present utility model, the first tie rod 100 includes a first connector 120 and a first tube 130.

The first connecting member 120 is rotatably disposed at an end of the first pipe body 130 away from the second pull rod 300, that is, the first connecting member 120 is rotatably connected with the first pipe body 130.

Specifically, the first connecting member 120 and the first pipe 130 can rotate about the axis of the first pull rod 100.

In addition, one end of the first connection member 120 facing away from the first tube body 130 is provided with a first connection hole so that an external carrier can be connected with the first connection member 120 through the first connection hole.

In the present embodiment, the inner wall of the first tube 130 defines a first convex ring 131, the first convex ring 131 is disposed at an end of the first tube 130 away from the second pull rod 300, and an axis of the first convex ring 131 coincides with an axis of the first tube 130.

The number of the first convex rings 131 may be one, two or more than two, and may be specifically set according to practical situations.

In addition, a first annular groove 121 is formed in the circumferential direction of the first connecting member 120, and an axis of the first annular groove 121 coincides with an axis of the first connecting member 120.

Specifically, the number of the first convex rings 131 is equal to the number of the first annular grooves 121, the first convex rings 131 are disposed in the first annular grooves 121, the outer walls of the first convex rings 131 are in contact with the inner walls of the first annular grooves 121, and the first convex rings 131 can rotate in the first annular grooves 121, so that the first connecting piece 120 can rotate relative to the first pipe body 130.

It will be appreciated that a portion of the first connector 120 is disposed inside the first tube 130 to form a stop between the first connector 120 and the first tube 130 by the first collar 131 and the first annular groove 121, thereby preventing the first tube 130 and the first connector 120 from moving relatively in the first direction.

In this embodiment, the number of the first convex rings 131 and the first annular grooves 121 is two, the two first convex rings 131 are disposed at intervals along the first direction, and the two first annular grooves 121 are disposed at intervals along the first direction, so as to improve the stability of the connection between the first connecting member 120 and the first pipe 130, and prevent the first connecting member 120 from separating from the first pipe 130.

As shown in fig. 2, 4 and 5, in some embodiments of the present utility model, the second tie rod 300 includes a second connector 310 and a second tube 320.

The second connecting member 310 is rotatably disposed at an end of the second tube 320 away from the first pull rod 100, that is, the second connecting member 310 is rotatably connected to the second tube 320.

Specifically, the second connector 310 and the second pipe 320 can rotate about the axis of the second pull rod 300.

In addition, the end of the second connection member 310 facing away from the second tube body 320 is provided with a second connection hole so that an external carrier can be connected with the second connection member 310 through the second connection hole.

In this embodiment, the inner wall of the second pipe body 320 defines a second convex ring 321, the second convex ring 321 is disposed at an end of the second pipe body 320 away from the first pull rod 100, and an axis of the second convex ring 321 coincides with an axis of the second pipe body 320.

The number of the second convex rings 321 may be one, two or more than two arbitrary values, which may be specifically set according to practical situations.

In addition, a second annular groove 311 is formed in the circumferential direction of the second connecting member 310, and an axis of the second annular groove 311 coincides with an axis of the second connecting member 310.
