Description

Technical Field

[0001] This application relates to the technical field of fans, and in particular to a plug-in support structure for fans. Background Technology

[0002] Fans are commonly used cooling devices in people's daily lives, and the market mainly offers desktop fans and floor fans.

[0003] Desktop fan stands typically have short poles or stands, limiting their height and airflow range to a short distance on the desktop, making them unsuitable for users in larger spaces. Floor fans, on the other hand, usually have taller poles, offering a wider airflow range, but their overall height results in low space utilization, making them unsuitable for use on small platforms such as desktops.

[0004] Desktop fans and floor fans each cater to limited scenarios. Although fans with extendable poles are available on the market, their adjustment range is also limited, making it difficult to achieve significant height changes from desktop to floor fan. If users have multiple usage needs, they will need to purchase different types of fans, which not only increases costs but also occupies more storage space. Summary of the Invention

[0005] To improve the applicability of fans, this application provides a plug-in support structure for fans.

[0006] This application provides a plug-in support structure for a fan, employing the following technical solution: A plug-in support structure for a fan includes: a base and a support body, wherein the support body is mounted on the base for supporting the fan head; The upright body includes a base rod, a segment group, and a connector. The base rod is disposed on the base. The segment group is detachably connected to the base rod. The connector is connected to the fan head and can be detachably connected to the segment group or the base rod. The segment group includes multiple segment rods, and the multiple segment rods can be detachably spliced ​​together in sequence.

[0007] By adopting the above technical solution, the pole body features a detachable and modular segment design, allowing users to flexibly adjust the pole height according to actual needs and quickly switch from a desktop fan to a floor fan. The modular design of the base pole, segment poles, and connectors not only simplifies the assembly and storage process but also improves the product's versatility and adaptability, meeting the usage needs of different scenarios.

[0008] Optionally, the two ends of the segment rod that are far apart from each other are a plug-in end and a sleeve end, respectively. The plug-in end has a plug-in portion extending out of the end of the segment rod, and the sleeve end has a first sleeve groove for fitting the plug-in portion of the adjacent segment rod. The plug-in end also has a first threaded sleeve, which is used to be threaded onto the outer wall of the sleeve end of the adjacent segment rod.

[0009] By adopting the above technical solution, the mating design of the plug end and the sleeve end, combined with the threaded fixing method of the first threaded sleeve, ensures the stability and reliability of the connection between the segment rods. The plug-in structure of the plug part and the first sleeve groove facilitates quick assembly, while the thread locking of the first threaded sleeve further enhances the connection strength and prevents loosening or falling off during use.

[0010] Optionally, the inner wall of the first threaded sleeve has a protrusion, and the outer periphery of the insertion end is provided with a movable annular groove, which is used to allow the protrusion to rotate and move along the length direction of the segment rod.

[0011] By adopting the above technical solution, the cooperation between the movable annular groove and the protrusion allows the first threaded sleeve to rotate and move flexibly on the segment rod, making it easy for users to quickly complete the installation and removal of the threaded sleeve.

[0012] Optionally, the base rod has an insert rod extending from one end of the base rod away from the base, and the base rod is movably fitted with a second threaded sleeve; the connector has a second socket groove; the insert rod is used to insert into the first socket groove or the second socket groove, and the second threaded sleeve is used to be threaded onto the socket end or the connector.

[0013] By adopting the above technical solution, the engagement of the base rod's insert and the second threaded sleeve enables a quick connection between the base rod and the segment assembly or connector. After the insert is inserted into the first or second socket, the threaded locking of the second threaded sleeve ensures the robustness of the connection, while also allowing users to flexibly adjust the pole structure according to their needs.

[0014] Optionally, the base rod is hinged to the base; when the base rod is perpendicular to the base and connected to the segment rod or the connector, the base rod can be positioned relative to the base.

[0015] By adopting the above technical solution, the hinged design of the base pole allows the upright structure to be folded and stored, significantly reducing the space occupied.

[0016] Optionally, the base is provided with a ball-head plunger, and the base rod is provided with a first abutment groove and a second abutment groove for the ball head of the ball-head plunger to abut into; when the ball-head plunger is engaged with the first abutment groove, the axis of the base rod is parallel to the base; when the ball-head plunger is engaged with the second abutment groove, the base rod is perpendicular to the base.

[0017] By adopting the above technical solution, the cooperation between the ball plunger and the abutment groove enables the rapid positioning of the base rod at different angles.

[0018] Optionally, the base has a receiving cavity corresponding to each segment rod, the receiving cavity being used to store the corresponding segment rod.

[0019] By adopting the above technical solution, the accommodating cavity on the base provides a dedicated storage space for the segmented rods, making it convenient for users to classify and store them and quickly access them.

[0020] Optionally, the first threaded sleeve has an external thread on its outer periphery, and when the segment rod is inserted into the receiving cavity, the first threaded sleeve can be threadedly connected to the inner wall of the receiving cavity.

[0021] By adopting the above technical solution, the external thread of the first threaded sleeve and the threaded engagement of the inner wall of the accommodating cavity achieve the fixation of the segment rod during storage, preventing it from accidentally falling off, and further improving the stability and convenience of storage.

[0022] Optionally, when the segment rod is housed in the base, the plug-in portion is located outside the base, and the base has a first support state and a second support state; the first support state is characterized by the lower surface of the base abutting against the placement surface; the second support state is characterized by two of the segment rod plug-in portions jointly supporting the placement surface, while another segment rod extends vertically to connect to and support the connector.

[0023] By adopting the above technical solution, the two support states of the base adapt to the needs of different usage scenarios. The first support state is suitable for placement on a regular desktop or floor, while the second support state, supported by the insertion part of the segmented rod, is suitable for environments with limited space, thus improving the product's versatility.

[0024] In summary, this application includes at least one of the following beneficial effects: 1. Through the modular segmented pole design, users can freely splice the pole height according to their needs, achieving a seamless switch from desktop fan to floor fan, meeting a variety of usage scenarios; 2. The hinged design of the base pole and the accommodating cavity structure of the base allow the pole to be quickly folded and categorized for storage, significantly reducing space occupation and making it easy to store and carry.

[0027] The following is in conjunction with the appendix Figure 1 To be continued Figure 8 This application will be described in further detail.

[0028] This application discloses a plug-in support structure for a fan. (Refer to...) Figure 1 The fan's plug-in support structure includes a base 1 and a support body. The support body is installed on the base 1 to support the fan head, and the support body can be deformed so that the fan can be used as a desktop fan or a floor fan.

[0029] The base 1 is disc-shaped, and the upright body is installed at the center of the base 1. The upright body includes a base rod 2, segment assembly 3, and connector 4. The base rod 2 is installed on the base 1, the segment assembly 3 is detachably installed on the base rod 2, and the connector 4 can be detachably connected to either the base rod 2 or the segment assembly 3 as needed, and the connector 4 is connected to the fan head. When the connector 4 is connected to the base rod 2, the overall height of the fan is suitable for use as a desktop fan; when the segment assembly 3 is connected between the base rod 2 and the connector 4, the overall height of the fan is suitable for use as a floor fan.

[0030] The fan head can be fixed to the connector 4 or rotatably connected to the connector 4. When the fan head is rotatably connected to the connector 4, the connector 4 is equipped with a rotational power to drive the fan head to rotate. The connection method between the fan head and the connector 4 is existing technology and will not be described in detail here.

[0031] Reference Figure 1 and Figure 2 It should be noted that the segment group 3 includes multiple sequentially detachable and splicable segment rods 31. The length of the segment group 3 can be adjusted by changing the number of segment rods 31. Specifically, the segment rods 31 are round rods, and the two ends of the segment rods 31 that are far apart from each other are the insertion end 5 and the sleeve end 6, respectively.

[0032] The insertion end 5 has an insertion portion 7, which is fixed at the center of the end face of the insertion end 5 and is in the shape of a square rod, and extends away from the sleeve end 6. A cylindrical first threaded sleeve 9 is also coaxially slidably fitted on the outer periphery of the insertion end 5. The inner diameter of the first threaded sleeve 9 is the same as the outer diameter of the segment rod 31. The first threaded sleeve 9 includes an external threaded section 91 and an internal threaded section 92 connected sequentially along its own axial direction. The external threaded section 91 has threads on its outer periphery, and the internal threaded section 92 has threads on its inner periphery (not shown in the figure). The external threaded section 91 is closer to the sleeve end 6 than the internal threaded section 92.

[0033] Furthermore, a protrusion 10 is fixed on the inner wall of the first threaded sleeve 9 at the junction of the external thread section 91 and the internal thread section 92. The protrusion 10 is an annular shape coaxial with the first threaded sleeve 9 and protrudes from the inner wall of the first threaded sleeve 9. A movable annular groove 11 is coaxially provided on the outer periphery of the insertion end 5 for the protrusion 10 to abut and move. The opening length of the movable annular groove 11 along the axial direction of the segment rod 31 is greater than the extension length of the protrusion 10 along the axial direction of the first threaded sleeve 9, and the movable annular groove 11 does not penetrate the end of the segment rod 31.

[0034] A first socket groove 8 is provided at the center of the end face of the socket end 6. The first socket groove 8 is used for the protrusion 10 to be inserted, and the outer periphery of the socket end 6 is provided with external threads.

[0035] When two adjacent rod segments 31 are engaged, the insertion part 7 of one rod segment 31 is inserted into the first sleeve groove 8 of the other rod segment 31, so that the end face of the insertion end 5 of one rod segment 31 abuts against the end face of the sleeve end 6 of the other rod segment 31. Then, the first threaded sleeve 9 on one rod segment 31 is threaded onto the outer periphery of the sleeve end 6 of the other rod segment 31 through the internal thread section 92, so as to realize the connection and fixation of the two adjacent rod segments 31.

[0036] Reference Figure 2 , Figure 3 and Figure 4 For the base rod 2 and the connector 4, the base rod 2 is round and has a plug rod 12. The plug rod 12 is square and extends from the top of the base rod 2 along its length. A second threaded sleeve 13 is movably fitted onto the top of the base rod 2. The movement of the second threaded sleeve 13 on the base rod 2 is the same as the movement of the first threaded sleeve 9 on the segment rod 31, and the second threaded sleeve 13 has internal threads (not shown in the figure). A second fitting groove 14 is provided at the bottom of the connector 4 for fitting the plug part 7 or the plug rod 12. The outer circumference of the bottom of the connector 4 has external threads.

[0037] When the base rod 2 mates with the segment group 3, the sleeve end 6 of the bottom segment rod 31 of the segment group 3 faces downward, and the insert rod 12 is sleeved downward on the sleeve end 6. Then, the second threaded sleeve 13 is threaded onto the sleeve end 6 to achieve the connection between the base rod 2 and the segment group 3. When the segment group 3 mates with the connector 4, the insert end 5 of the top segment rod 31 of the segment group 3 faces upward, and the connector 4 is sleeved downward on the top insert part 7 of the segment group 3 through the second sleeve groove 14, so that the bottom end of the connector 4 abuts against the top end of the insert end 5. Then, the first threaded sleeve 9 on the insert end 5 is threaded onto the connector 4 to achieve the connection between the segment group 3 and the connector 4. When segment group 3 is removed and connector 4 is engaged with base rod 2, the second sleeve groove 14 of connector 4 is fitted onto insert rod 12 so that connector 4 abuts against end face of base rod 2. Then, the second threaded sleeve 13 on base rod 2 is threaded onto connector 4 to achieve connection between connector 4 and base rod 2.

[0038] Reference Figure 1 and Figure 3Furthermore, to improve storage convenience, a rotating seat 19 is fixed to the bottom of the base rod 2. The axis of the rotating seat 19 extends horizontally, and a hinge seat 20 is fixed to the upper surface of the base 1. The hinge seat 20 and the rotating seat 19 are rotatably engaged, so that the base rod 2 is hinged to the base 1. When the base 1 is used as a base to support the entire fan, the base rod 2 is coaxial with the base 1. When the fan needs to be stored, the base rod 2, the segment rod 31, and the connector 4 are separated. The base rod 2 rotates 90°, so that the side wall of the base rod 2 abuts against the surface of the base 1, thereby folding the base 1 and the base rod 2 relative to each other and reducing the space occupied. It should be noted that a clearance groove 21 is provided on the upper surface of the base 1 to accommodate the second threaded sleeve 13 of the base rod 2.

[0039] Reference Figure 3 and Figure 4 The insertion rod 12 slides along the axis of the base rod 2 and is mounted on the base rod 2. A slot 22 is provided on the base 1 for the insertion rod 12 to be inserted. When the base rod 2 and the base 1 are coaxial, the bottom of the insertion rod 12 is opposite to the slot 22, allowing the bottom of the insertion rod 12 to be inserted into the slot 22. When the insertion rod 12 is inserted into the slot 22, and simultaneously the segment rod 31 or the connector 4 is connected to the base rod 2, the top wall of the first groove 8 of the segment rod 31 or the top wall of the second groove 14 of the connector 4 abuts against the top wall of the insertion rod 12, thus restricting the insertion rod 12 from moving upwards and positioning the base rod 2 and the base 1, limiting the rotation of the base rod 2. When both the segment rod 31 and the connector 4 are removed from the base rod 2, the insertion rod 12 is pulled upwards out of the slot 22, allowing the base rod 2 to be rotated and adjusted.

[0040] To improve the ease of adjusting the position of the base rod 2, a ball-head plunger 15 is embedded in the base 1, with the ball head of the plunger 15 protruding from the upper surface of the base 1. A first abutment groove 16 and a second abutment groove 17 are circumferentially formed on the rotating seat 19 of the base rod 2. Both the first abutment groove 16 and the second abutment groove 17 are arc-shaped and used to engage with the ball-head plunger 15. When the base rod 2 is coaxial with the base 1, the ball head of the ball-head plunger 15 abuts into the first abutment groove 16 via the spring of the ball-head plunger 15. When the base rod 2 is bent by external force until its axis is perpendicular to the axis of the base 1, causing the outer wall of the base rod 2 to abut against the surface of the base 1, the ball head of the ball-head plunger 15 leaves the first abutment groove 16 and abuts into the second abutment groove 17. Thus, through the engagement of the ball-head plunger 15 with the first abutment groove 16 and the second abutment groove 17, the ball-head plunger 15 achieves initial positioning of the base rod 2 in different states.

[0041] Reference Figure 1 and Figure 6Furthermore, the base 1 has accommodating cavities 18 corresponding to the segment rods 31. These accommodating cavities 18 are formed radially from the circumference of the base 1 towards its center, and multiple accommodating cavities 18 are spaced apart along the circumference of the base 1. Specifically, each accommodating cavity 18 includes a connecting cavity 181 and a limiting cavity 182 that are coaxially connected sequentially from the circumference of the base 1 towards its center. The inner diameter of the connecting cavity 181 is the same as the outer diameter of the first threaded sleeve 9, and the inner diameter of the limiting cavity 182 is the same as the outer diameter of the segment rod 31. The connecting cavity 181 also has internal threads (not shown in the figure).

[0042] Reference Figure 1 , Figure 2 and Figure 6 When the segment rod 31 is engaged with the corresponding receiving cavity 18, it is inserted radially into the receiving cavity 18 with the sleeve end 6 facing the center of the base 1. Then, the first threaded sleeve 9 is moved so that the external threaded section 91 is threadedly connected to the inner wall of the connecting cavity 181, the protrusion 10 abuts against the inner end wall of the movable annular groove 11 near the sleeve end 6, and at the same time, the end of the sleeve end 6 abuts against the inner wall of the limiting cavity 182 away from the connecting cavity 181, so that the segment rod 31 is limited relative to the base 1, and the insertion part 7 is located outside the base 1.

[0043] Reference Figure 1 , Figure 7 and Figure 8 Furthermore, the base 1 has a first support state and a second support state for supporting the fan head. When the base 1 is in the first support state, the base rod 2 is coaxial with the base 1, and the base 1 abuts against the placement surface through its lower surface. When the base 1 is in the second support state, the axis of the base rod 2 is perpendicular to the axis of the base 1, and the base 1 houses at least three segment rods 31. Two of the segment rods 31 are located on both sides of the base rod 2, and the lowest point of the insertion part 7 of the two segment rods 31 is flush with the lowest point of the base rod 2. The two segment rods 31 and the base rod 2 are supported on the placement surface together. The other segment rod 31 is located above the base rod 2 and extends vertically. This segment rod 31 can be connected to the connector 4 through its own first threaded sleeve 9, or it can be connected to the connector 4 by splicing other connecting rods. It should be noted that, in order to enable the first threaded sleeve 9 on the segment rod 31 used to connect the connector 4 to the base 1 when the base 1 is in the second support state, the opening depth of the limiting cavity 182 corresponding to this segment rod 31 is deeper than the opening depth of other limiting cavities 182.

[0044] When the base 1 is in the second support state, the area occupied by the upright structure on the placement surface is smaller than the area occupied by the base 1 when it is in the first support state, so as to adapt to the situation of narrow placement space.

[0045] The implementation principle of the plug-in support structure for a fan in this embodiment is as follows: the segment rods 31 are quickly connected through the cooperation of the plug end 5 and the sleeve end 6, and are fixed by the threaded sleeve to ensure stability. The base rod 2 is hinged to the base 1 and can be folded for storage. The accommodating cavity 18 on the base 1 is used to classify and store the segment rods 31.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
