Technical Field

[0001] This utility model relates to the field of telescopic pole unlocking technology, and in particular to a telescopic pole unlocking device. Background Technology

[0002] Telescopic poles can be used in various devices such as clothes dryers and clothes racks. Their telescopic function allows for length adjustment to suit different usage scenarios. However, traditional telescopic poles either lack an unlocking mechanism or have a complex unlocking mechanism, making unlocking inconvenient and hindering length adjustment. Therefore, improvements are needed to address this shortcoming of telescopic poles. Utility Model Content

[0003] Therefore, it is necessary to provide a telescopic pole unlocking device to address the problem that traditional telescopic poles lack an unlocking structure or have a complex unlocking structure, making unlocking inconvenient and thus hindering the length adjustment of the telescopic pole.

[0004] A telescopic pole unlocking device includes: a housing assembly; a telescopic pole assembly disposed on the housing assembly; a locking assembly disposed on the telescopic pole assembly for locking or unlocking the telescopic pole assembly; and a control key assembly disposed on the housing assembly, capable of driving the locking assembly to move relative to the telescopic pole assembly. When the locking assembly moves relative to the telescopic pole assembly, it has at least a first position and a second position. When the locking assembly is in the first position, it locks the telescopic pole assembly; when the locking assembly is in the second position, it unlocks the telescopic pole assembly.

[0005] This application discloses a telescopic rod unlocking device. The telescopic rod assembly can be freely adjusted in length to adapt to different usage scenarios. The locking component ensures reliable locking after the telescopic rod assembly is adjusted to the desired length, guaranteeing a fixed length during use. The control key component enables unlocking of the telescopic rod assembly. The structure is relatively simple, effectively reducing production costs and improving economic efficiency. Unlocking the telescopic rod assembly is achieved by moving the control key component relative to the telescopic rod assembly, which pushes the locking component. This unlocking method simplifies the operation, allowing users to unlock with just one hand, resulting in a more convenient and reliable unlocking process. After unlocking, the telescopic rod can be smoothly adjusted, improving usability. The telescopic rod unlocking device of this application has a simple and reasonable structural design. The control key component unlocks by directly pushing the locking component, resulting in strong stability, reliability, and ease of use.

[0006] In one embodiment, the control key assembly is movable relative to the housing assembly, and when movable relative to the housing assembly, the control key assembly has at least a third position and a fourth position. When the control key assembly is in the third position, the locking assembly is in the first position, and when the control key assembly is in the fourth position, the locking assembly is in the second position. Locking and unlocking of the telescopic rod assembly can be achieved by moving the control key assembly relative to the housing assembly, making the locking and unlocking operations simpler and more intuitive. This design ensures accurate locking or unlocking every time, improving ease of use.

[0007] In one embodiment, the housing assembly has a receiving groove, or the housing assembly and the telescopic rod assembly enclose and form a receiving groove. The control key assembly is disposed on the housing assembly and located within the receiving groove, and the control key assembly is movable along the depth direction of the receiving groove. The receiving groove provides precise movement guidance for the control key assembly, ensuring smooth movement in a predetermined direction and preventing deviation or jamming during operation. Furthermore, the receiving groove limits the movement range of the control key assembly, ensuring sufficient operating stroke while effectively preventing mechanism failure due to overtravel.

[0008] In one embodiment, the housing assembly has an opening that communicates with the receiving groove. The control key assembly can pass through the opening and extend to the outside of the housing assembly. By extending the control key assembly through the opening to the outside of the housing, the operating part is directly exposed, facilitating user access and force application. The communication between the opening and the receiving groove maintains the guiding movement characteristics of the control key assembly within the receiving groove while fulfilling the functional requirements for external operation.

[0009] In one embodiment, the wall of the receiving groove and one of the control key assemblies form a guide block, and the wall of the receiving groove and the other of the control key assemblies are provided with a sliding groove, with the guide block engaging with the sliding groove. The engagement of the guide block and the sliding groove ensures that the control key assembly moves along a straight trajectory, eliminating deviation or wobbling during movement. This design makes the movement of the control key assembly smoother and more reliable.

[0010] In one embodiment, the control key assembly includes a button structure and a resilient element. The button structure is disposed on the housing assembly and is movable relative to the housing assembly. The button structure can drive the locking assembly to move relative to the telescopic rod assembly. The two ends of the resilient element abut against the button structure and the telescopic rod assembly, respectively. The resilient element applies a force to the button structure away from the locking assembly. By continuously applying a force away from the locking assembly to the control key assembly through the resilient element, the control key assembly remains abutted against the housing assembly, ensuring that the button structure remains in a stable position and preventing it from loosening. Furthermore, the resilient element automatically resets the button structure to its initial position after an unlocking operation, preparing it for the next operation.

[0011] In one embodiment, the button structure includes a button body and a push block. The button body is disposed on the housing assembly and is movable relative to the housing assembly. The push block is disposed on the button body and can drive the locking assembly to move relative to the telescopic rod assembly. The button body provides the user with a basis for pressing to unlock. The push block drives the locking assembly to move, accurately transmitting the button operation force to the locking assembly, ensuring a direct and effective pushing effect on the locking assembly.

[0012] In one embodiment, the push block includes a first push portion and a second push portion, both of which are disposed on the button body and intersect. Both the first and second push portions are capable of pushing the locking component relative to the telescopic rod assembly. The first and second push portions support each other, forming a structure that stably pushes the locking component, enhancing the overall strength of the push block and preventing deformation or breakage. This design reduces material usage while ensuring sufficient strength, making it highly practical.

[0013] In one embodiment, the elastic element is fitted onto the push block. This elastic element ensures a tighter fit and more stable force transmission.

[0014] In one embodiment, the button body includes a first movable part and a second movable part. The first movable part is capable of abutting against the housing assembly, and the second movable part is disposed on the first movable part, passing through the housing assembly and extending to the outside of the housing assembly. The abutment between the first movable part and the housing assembly forms a physical limit, effectively restricting the degree of freedom of the button body and preventing the button body from accidentally dislodging from the housing assembly. The second movable part extending to the outside of the housing provides a clear operating contact surface, facilitating direct force application and control by the user.

[0015] In one embodiment, the housing assembly includes a housing body, a first protrusion, and a second protrusion. The telescopic rod assembly is disposed on the housing body. Both the first and second protrusions are located on the housing assembly. The first protrusion has a receiving groove, or the first protrusion and the housing body enclose a receiving groove. A first movable part is disposed on the first protrusion and located at the receiving groove. The first movable part can abut or separate from the second protrusion. The second protrusion has an opening communicating with the receiving groove, and the second movable part is located at the opening. The receiving groove formed by the first protrusion provides a precise installation position for the first movable part, ensuring its stable movement trajectory. The abutting cooperation between the first movable part and the second protrusion forms a physical limit, preventing the entire button structure from detaching from the housing assembly.

[0016] In one embodiment, the telescopic rod assembly includes a first rod and a second rod, the second rod being disposed on the first rod. The first rod has a first limiting hole, and the second rod has a second limiting hole. When the locking component locks the telescopic rod assembly, the locking component passes through the first limiting hole and the second limiting hole. When the telescopic rod assembly is unlocked, the locking component exits from the first limiting hole. The locking component forms a mechanical interlock when passing through the first and second limiting holes, ensuring the telescopic rod assembly is stable and does not loosen in the locked state. Unlocking only requires the locking component to exit from the first limiting hole, making the operation simple and direct. This design improves locking reliability, ease of operation, and adjustment flexibility.

[0017] In one embodiment, the locking assembly includes a support structure and a locking member. The support structure is disposed on and inside the telescopic rod assembly, and the locking member is movably disposed on the support structure. The control key assembly can drive the locking member to move relative to the telescopic rod assembly. The support structure provides a stable support base for the locking member, ensuring stable movement of the locking member. The locking member has a simple structure, can securely lock the telescopic rod assembly, and provides a good locking effect. Attached Figure Description

The control key component 4 enables unlocking of the telescopic rod assembly 2. The structure is relatively simple, effectively reducing production costs and improving economic efficiency. Moving the control key component 4 relative to the telescopic rod assembly 2 pushes the locking component 3, thus unlocking the telescopic rod assembly 2. This unlocking method simplifies the operation, allowing users to unlock with just one hand, achieving a more convenient and reliable unlocking operation. After unlocking, the telescopic rod can be smoothly adjusted, improving usability. The telescopic rod unlocking device of this application has a simple and reasonable structural design. The control key component 4 unlocks by directly pushing the locking component 3, resulting in strong stability, reliability, and ease of use.

This design reduces material usage while ensuring sufficient strength, making it highly practical.

[0052] like Figure 3-6 and Figure 11-12 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the elastic element 42 is sleeved on the push block 412. The elastic element 42 sleeved on the push block 412 makes the fit tighter, ensuring more stable force transmission.

The locking component 3 forms a mechanical interlock when it passes through the first limiting hole 201 and the second limiting hole 202, ensuring that the telescopic rod assembly 2 is stable and does not loosen in the locked state. When unlocking, the locking component 3 only needs to exit from the first limiting hole 201, making the operation simple and direct. This design can improve locking reliability, ease of operation, and adjustment flexibility.
