Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a fan with a telescopic rod that can be easily disassembled. Background Technology

[0002] With the increasing demand for miniaturization and portability of household appliances, the traditional fixed structure of fans is gradually becoming insufficient to meet users' needs for flexible use and convenient storage. In existing technologies, fan support rods mostly adopt a one-piece design or a simple threaded connection structure, which has the following drawbacks:

[0003] Non-adjustable or cumbersome to adjust: Most fans have a fixed support rod height, which cannot adapt to different scenarios (such as desktop or floor use); a few fans with telescopic structures rely on knobs or screws for fixing, and adjustment requires tools and involves complicated steps.

[0004] Disassembly is difficult: The support rod is rigidly connected to the base and fan head, which results in a large space occupation during storage and high transportation costs. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a fan with a telescopic rod that can be easily disassembled, so as to solve the problems in the background art.

[0006] In view of this, the present invention provides a fan with a telescopic rod that can be easily disassembled, comprising:

[0007] The base has a plug-in terminal on its top;

[0008] The upright pole has its lower end inserted into the top of the base and electrically connected to the plug-in terminal.

[0009] A telescopic rod is sleeved inside the upright and can extend and retract axially. The surface of the telescopic rod is provided with several positioning grooves.

[0010] The pressing and positioning components are respectively installed on the upright and the base. The pressing and positioning component on the base is used to realize the snap-fit ​​positioning between the base and the upright, and the pressing and positioning component on the upright is used to realize the snap-fit ​​positioning between the upright and the telescopic rod.

[0011] The fan head is fixedly connected to the top of the telescopic rod.

[0012] Preferably, the pressing and positioning component includes a button, a rotating shaft, and a locking member. The button is connected to one end of the locking member, and the locking member is rotatably connected to the upright and the base via the rotating shaft. The locking member can disengage and be positioned when pressed by the button.

[0013] Preferably, when the pressing and positioning assembly is located on the base, the snap-fit ​​component included in the pressing and positioning assembly snaps into the positioning groove on the inner wall of the upright;

[0014] When the pressing and positioning assembly is located on the upright, the snap-fit ​​component included in the pressing and positioning assembly snaps into the positioning groove.

[0015] Preferably, the button and the latching component are a flexible integrated structure, and when the button is pressed, the other end of the latching component is forced to disengage through the pivot.

[0016] Preferably, the cross-section of the upright and telescopic pole is circular, square, or polygonal.

[0017] As can be seen from the above technical solutions, the embodiments of this utility model have the following advantages:

[0018] 1. This utility model discloses a telescopic fan with a easily detachable telescopic rod. Utilizing the elastic locking mechanism and positioning groove of the press-and-position component, the user only needs to press the button once to unlock the telescopic rod, achieving stepless height adjustment or quick overall disassembly without the need for tools, increasing operational efficiency by over 50%. The telescopic rod, upright pole, and fan head can be completely separated; after disassembly, each component can be stored independently, reducing space occupation by 60%-70%, facilitating transportation and home storage.

[0019] 2. The positioning grooves are evenly distributed and matched with wedge-shaped snap-fit ​​parts to form a self-locking structure, which prevents the telescopic rod from slipping off due to external force or vibration. The support stability is improved by more than 40% compared with the traditional friction structure.

Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0029] The following describes in detail, with reference to the accompanying drawings, an embodiment of the present invention: a fan with a telescopic rod that can be easily disassembled. Example

[0030] For easier understanding, please refer to Figures 1 to 5 An embodiment of a fan with a telescopic rod that can be easily disassembled, provided by this utility model, includes:

[0031] Base 1, the top of which is provided with a plug-in terminal 11;

[0032] The lower end of the upright 2 is inserted into the top of the base 1 and is electrically connected to the plug-in terminal 11;

[0033] The telescopic rod 3 is sleeved inside the upright 2 and can extend and retract axially. The surface of the telescopic rod 3 is provided with several positioning grooves 31.

[0034] The pressing and positioning components 4 are respectively set on the upright 2 and the base 1. The pressing and positioning components 4 on the base 1 are used to realize the snap-fit ​​positioning of the base 1 and the upright 2. The pressing and positioning components 4 on the upright 2 are used to realize the snap-fit ​​positioning of the upright 2 and the telescopic rod 3.

[0035] The fan head 5 is fixedly connected to the top of the telescopic rod 3. In an optional embodiment, the cross-section of the upright 2 and the telescopic rod 3 is circular, square, or polygonal.

[0036] It should be noted that the telescopic rod 3 is nested inside the upright rod 2 and its height is adjusted by pressing the positioning component 4. The upright rod 2 and the base 1 are also quickly disassembled and assembled by pressing the positioning component 4, thereby improving the portability and flexibility of the product.

[0037] The base 1 serves as the support component for the fan, with a cylindrical plug-in terminal 11 located at its top center. The plug-in terminal 11 integrates a conductive metal sheet for electrical connection with the electrode at the lower end of the upright 2. Two sets of pressing and positioning components 4 are symmetrically arranged on the side wall of the base 1, with their snap-fit ​​parts 43 insertable into the positioning grooves on the inner wall of the upright 2 to achieve snap-fit ​​fixation between the upright 2 and the base 1.

[0038] The upright 2 is a hollow tubular structure with a cross-section that can be circular, square, or polygonal. Its lower outer diameter matches the inner diameter of the insertion terminal 11 of the base 1, and it is locked in place by pressing and positioning components 4 after insertion. Several positioning grooves are spaced axially along the inner wall of the upright 2 to engage with the positioning groove 31 of the telescopic rod 3; simultaneously, another set of pressing and positioning components 4 is provided on the outer side of the middle section of the upright 2 to control the extension and locking of the telescopic rod 3.

[0039] The telescopic rod 3 is nested inside the upright rod 2, and its outer surface has multiple annular positioning grooves 31 evenly distributed along the axial direction. The top of the telescopic rod 3 is fixedly connected to the fan head 5 by threads or buckles. When the pressing positioning component 4 on the upright rod 2 is pressed, the locking piece 43 disengages from the current positioning groove 31. The user can adjust the telescopic rod 3 up and down to the target height and then release the button 41. The locking piece 43 automatically snaps into the corresponding positioning groove 31 to complete the locking.

[0040] The upright pole 2 has an internal conductive circuit. Its lower electrode is in contact with the plug terminal 11 of the base 1, and its upper end is connected to the motor of the fan head 5 through the wire inside the telescopic rod 3, forming a complete power supply circuit. When the upright pole 2 is disassembled, the plug terminal 11 automatically separates from the electrode of the upright pole 2, ensuring electrical safety.

[0041] In an optional embodiment: the pressing positioning component 4 includes a button 41, a rotating shaft 42 and a snap-fit ​​component 43. The button 41 is connected to one end of the snap-fit ​​component 43. The snap-fit ​​component 43 is rotatably connected to the upright 2 and the base 1 through the rotating shaft 42. When the snap-fit ​​component 43 is pressed by the button 41, it can disengage from the snap-fit ​​positioning.

[0042] It should be noted that the press positioning component 4 includes a button 41, a rotating shaft 42, and a locking member 43. The button 41 and the locking member 43 are hinged to the mounting groove of the upright 2 or the base 1 via the rotating shaft 42. The locking member 43 is an L-shaped metal piece, one end of which is connected to the button 41, and the other end is a wedge-shaped locking head.

[0043] In an optional embodiment: when the pressing positioning component 4 is located on the base 1, the snap-fit ​​component 43 included in the pressing positioning component 4 snaps into the positioning groove on the inner wall of the upright 2;

[0044] When the pressing and positioning component 4 is located on the upright 2, the snap-fit ​​component 43 included in the pressing and positioning component 4 snaps into the positioning groove 31.

[0045] It should be noted that, on the base 1, when the button 41 is pressed, the snap-fit ​​component 43 rotates around the pivot 42, causing the wedge-shaped snap head to disengage from the positioning groove on the inner wall of the upright 2, at which point the upright 2 can be pulled out.

[0046] The pressing and positioning component 4 on the upright 2: pressing the button 41 drives the snap-fit ​​43 to disengage from the positioning groove 31 of the telescopic rod 3, thereby realizing telescopic adjustment.

[0047] In an optional embodiment: the button 41 and the latch 43 are a flexible integrated structure, and when the button 41 is pressed, the other end of the latch 43 is forced to disengage through the pivot 42.

[0048] It should be noted that the button 41 and the latching component 43 are integrally molded from flexible plastic, and the latching and release are achieved through elastic deformation when pressed.

[0049] Working principle: Insert the upright 2 into the connector 11 of the base 1 until the pressing and positioning component 4 of the base 1 engages with the positioning groove of the upright 2, completing the mechanical and electrical connection. Press the button 41 on the upright 2, the locking component 43 disengages from the positioning groove 31 of the telescopic rod 3, slide the telescopic rod 3 up and down to the desired height, and then release the button 41 to lock it. Simultaneously press the buttons 41 on both sides of the base 1 to pull out the upright 2 and the telescopic rod 3, separating them into four independent parts: the base 1, the upright 2, the telescopic rod 3, and the fan head 5.
