[0002] The clothesline is the most commonly used device for drying clothes in daily life. Due to the limitations of different house types, some houses do not have balconies or the balcony space is small, and there is not enough space to set up the clothesline. Through searching, it was found that the prior art with announcement number CN215887645U requires a screw shaft and a fixing part for causing the screw shaft to rotate between its two rod bodies, that is, between the shell and the sliding part. Although the above problem can be solved, the sliding part cannot rotate in actual application, which makes it difficult to store the sliding part. Utility Model Content

[0003] The purpose of the utility model is to provide a telescopic clothes drying rod to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a telescopic clothes drying rod, comprising a base, a main rod body and a secondary rod body; one end of the main rod body is connected to the base shaft pin, and one end of the secondary rod body slides in the main rod body; a protrusion is also provided on the base; wherein a locking pin is also provided in the secondary rod body, and a through hole is also provided on the main rod body for exposing the locking pin outward; the locking pin is brought into contact with the protrusion by the rotation of the main rod body on the base; as the main rod body continues to rotate, the protrusion presses the locking pin into the secondary rod body to complete the unlocking of the secondary rod body.

[0005] As a preferred technical solution of the present utility model: a first spring is further provided at one end of the locking pin away from the protruding portion.

[0006] As a preferred technical solution of the utility model: a second spring is further provided below the auxiliary rod body, and after the locking pin is unlocked, the second spring forces the auxiliary rod body to move outward.

[0007] As a preferred technical solution of the utility model: a limit pin is further provided on the side of the main rod body away from the base, and the limit pin is used to prevent the locking pin from sliding outwards.

[0008] As a preferred technical solution of the utility model: the limit pin is adaptively connected to the connecting hole provided on the main rod body.

[0009] As a preferred technical solution of the present utility model: a receiving cavity for receiving the second spring is further provided below the auxiliary rod body.

[0010] By adopting the above technical scheme, the beneficial effects of the utility model are as follows: since the main rod body can rotate on the base, the main rod body can be folded when not in use, so that the contact surface of the main rod body and the base is parallel, thereby reducing the space occupied by the main rod body when it is placed horizontally; at the same time, the sub-rod body can slide inside the main rod body, so that the sub-rod body can be retracted into the main rod body, especially, the main rod body and the sub-rod body can be mutually locked after the locking pin passes through the through hole, and conversely, the sub-rod body can be automatically unlocked by utilizing the mutual cooperation between the locking pin and the protrusion, so that the main and sub-rod bodies have a stable and reliable connection relationship when locked, and the normal deployment of the sub-rod body is not affected when unlocked.

[0019] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0020] See also Figure 1-7 The utility model provides an embodiment: a telescopic clothes-drying rod, comprising a base 1, a main rod body 4 and a secondary rod body 6; characterized in that: one end of the main rod body 4 is connected to the base 1 with an axial pin, and one end of the secondary rod body 6 slides in the main rod body 4; a protrusion 2 is also provided on the base 1; wherein a locking pin 7 is also provided in the secondary rod body 6, and a through hole 11 is also provided on the main rod body 4 for exposing the locking pin 7 to the outside; the locking pin 7 is contacted with the protrusion 2 by the rotation of the main rod body 4 on the base 1; as the main rod body 4 continues to rotate, the protrusion 2 presses the locking pin 7 into the secondary rod body 6 to complete the unlocking of the secondary rod body 6.

[0021] In summary, since the main rod body 4 can rotate on the base 1, the main rod body 4 can be folded when not in use, so that the contact surface of the main rod body 4 and the base 1 are parallel, thereby reducing the space occupied by the main rod body 4 when it is placed horizontally; at the same time, the sub-rod body 6 can slide inside the main rod body 4, so that the sub-rod body 6 can be retracted into the main rod body 4, especially, the main rod body 4 and the sub-rod body 6 can be locked to each other after the locking pin 7 passes through the through hole 11, and conversely, the sub-rod body 6 can be automatically unlocked by the mutual cooperation of the locking pin 7 and the protrusion 2, so that the main and sub-rod bodies have a stable and reliable connection relationship when locked, and the normal deployment of the sub-rod body 6 is not affected when unlocked.

[0022] Furthermore, since the first spring 9 is also provided at the end of the locking pin 7 away from the protrusion 2, the first spring 9 can be used to force the locking pin 7 to always press against the inner wall surface of the main rod body 4 when there is no external force, so as to ensure that the auxiliary rod body 6 can be stably located in the main rod body 4; in addition, the first spring can also be used to force one end of the locking pin 7 to enter the through hole 11, thereby connecting the locking pin 7 and the through hole 11, so that one end of the locking pin 7 can be inserted into the through hole 11 to complete the locking action.

[0023] On the basis of the above scheme, since a second spring 10 is further provided under the sub-rod body 6, and after the locking pin 7 is unlocked, the second spring 10 prompts the sub-rod body 6 to move outward. Specifically, when the sub-rod body 6 continues to move toward the inside of the main rod body 4 until one end of the locking pin 7 is inserted into the through hole 11, the second spring 10 is compressed. When the main rod body 4 rotates counterclockwise, the protrusion 2 prompts the locking pin 7 to separate from the through hole 11. At this time, the compressed second spring 10 is reset, and during the resetting process, the sub-rod body 6 can be prompted to move outward in the main rod body 4, so that after the locking pin 7 is unlocked, the outer end of the sub-rod body 6 can automatically pop out to facilitate the user to pull out the sub-rod body 6. Based on this, when the main rod body 4 is laid flat, one end of the sub-rod body 6 can automatically pop out.

[0024] Furthermore, since a stop pin 8 is provided on the side of the main rod body 4 away from the base 1, and the stop pin 8 prevents the lock pin 7 from sliding outward, the stop pin 8 can be used to block the lock pin 7, thereby avoiding the problem that the secondary rod body 6 is completely pulled out of the main rod body 4 due to excessive pulling of the secondary rod body 6.

[0025] Specifically, the limit pin 8 is adapted to be connected with the connecting hole 3 provided on the main rod body 4, so that by disassembling the limit pin 8, the auxiliary rod body 6 can be easily and conveniently inserted into the main rod body 4; wherein, the connecting hole 3 is an internal threaded hole, and the limit pin 8 is threadedly matched with the connecting hole 3.

[0026] In addition, since a accommodating cavity 5 for accommodating the second spring 10 is provided below the secondary rod body 6, the accommodating cavity 5 can be used to prevent the secondary rod body 6 from being unable to automatically pop out due to the second spring 10 falling. At the same time, the setting of the accommodating cavity 5 can also guide the second spring 10 to contract or extend along the central axis of the accommodating cavity 5 to ensure that the secondary rod body 6 can be reliably popped out.

[0027] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
