Technical Field

[0001] This utility model relates to the field of electric fan bracket technology, and in particular to a telescopic and foldable combination electric fan bracket. Background Technology

[0002] Electric fans are necessities in both home and work. Compared to air conditioners, electric fans still hold a large market share due to their affordability and natural ventilation. For consumers, low price and ease of use are primary considerations when choosing an electric fan. Typically, in the home appliance industry, the base of an electric fan is made of long profiles or tubing, secured with screws and other connectors to form a stable base.

[0003] However, such brackets are heavy and inconvenient to assemble and disassemble, causing many inconveniences to moving or transporting household appliances. Moreover, most electric fan brackets require users to assemble them, and if users are not familiar with the assembly method, they need to spend time learning. In addition, the angle adjustment of the fan in traditional brackets is limited, making it difficult to meet the diverse needs of users for the direction of fan airflow in different scenarios. In order to address this technical problem, this application proposes a telescopic folding combination electric fan bracket. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a telescopic and foldable combination electric fan bracket. By rotating and adjusting the extension angle of the sleeve and the height of the anti-slip support feet, the overall volume is reduced, making it easy to store and carry and improving practicality. Furthermore, by adjusting the angle of the mounting block, the angle of the fan can be adjusted, allowing users to precisely blow air to different positions and meet diverse usage scenarios.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A telescopic folding combination electric fan bracket includes a support rod, with multiple fixing lugs fixedly connected to the upper side of the outer wall of the support rod. A sleeve is rotatably connected to the middle of each fixing lug. The outer wall of the sleeve is connected to the inside of the support rod through an adjustment component. An anti-slip support foot is connected to the lower end of the sleeve through a telescopic component. An adjustment seat is installed at the upper end of the support rod, and an installation block is connected to the inside of the adjustment seat through a rotating component.

[0007] Furthermore, the adjustment assembly includes an adjustment knob rotatably connected to the lower end of the support rod, a screw fixedly connected to the middle of the adjustment knob, and the ends of the screw rotatably connected to the upper and lower ends of the inner wall of the support rod.

[0008] Furthermore, the adjustment assembly also includes a slider that is internally slidably connected to the support rod. The middle part of the slider is threadedly connected to the outer wall of the screw. The outer wall of the support rod has multiple grooves. The outer wall of the slider is fixedly connected to multiple fixing ears 2 at the positions corresponding to the grooves. The middle part of the fixing ears 2 is rotatably connected to a connecting rod. The upper end of the connecting rod is rotatably connected to a fixing ear 3. The outer end of the fixing ear 3 is fixedly connected to the upper side of the outer wall of the sleeve.

[0009] Furthermore, the telescopic assembly includes an adjustment knob two rotatably connected to the lower side of the outer wall of the sleeve, a worm gear fixedly connected to the middle of the adjustment knob two, a worm wheel meshing with the outer wall of the worm gear, a screw two threadedly connected to the middle of the worm wheel, a limit plate fixedly connected to the upper end of the screw two, the outer wall of the limit plate slidably connected to the inner wall of the sleeve, and the lower end of the screw two fixedly connected to the upper end of the anti-slip support foot.

[0010] Furthermore, the worm gear is provided with fixing plates on both the upper and lower sides, the outer wall of the fixing plate is fixedly connected to the lower inner side of the sleeve, and the middle part of the fixing plate is threadedly connected to the outer wall of the screw.

[0011] Furthermore, the rotating assembly includes an adjusting knob three rotatably connected to the front end of the adjusting seat, a rotating shaft fixedly connected to the middle of the adjusting knob three, a chuck fixedly connected to the front side of the outer wall of the rotating shaft, an empty chamber provided at the front end of the adjusting seat, the rear end of the chuck rotatably connected to the rear side inside the empty chamber, the rear side of the outer wall of the rotating shaft fixedly connected to the lower part of the mounting block, and the rear end of the rotating shaft rotatably connected to the rear end of the inner side of the adjusting seat.

[0012] Furthermore, a fixing rod is fixedly connected to the rear end of the empty compartment, and a locking rod is rotatably connected to the lower end of the fixing rod.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, rotating the second adjustment knob drives the worm gear to rotate, which in turn drives the worm wheel, causing the second screw to retract the anti-slip support foot into the sleeve, reducing the longitudinal space occupied by the sleeve. Rotating the first adjustment knob adjusts the sleeve angle, facilitating its retraction towards the support rod and reducing the overall size, thus making it easier to store and carry, improving practicality. Furthermore, by operating the first and second adjustment knobs, users can easily adjust the corresponding components by simply rotating the knobs, without the need for complex tools, thus improving fan installation efficiency.

[0016] In this utility model, by setting an adjustment knob three, a rotating shaft, a chuck, a locking rod and a tension spring in the adjustment seat, when the adjustment seat is installed on the support rod, the adjustment knob three can drive the mounting block to rotate. Under the action of the tension spring, it is fixed at different angles, thereby fixing the installed fan at different angles, so that users can accurately blow air to different positions and meet diverse usage scenarios.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 and Figure 2This utility model provides an embodiment of a telescopic folding combination electric fan bracket, including a support rod 1. Multiple fixing ears 2 are fixedly connected to the upper side of the outer wall of the support rod 1. A sleeve 3 is rotatably connected to the middle of each fixing ear 2. The outer wall of the sleeve 3 is connected to the interior of the support rod 1 via an adjustment assembly. The adjustment assembly includes an adjustment knob 7 rotatably connected to the lower end of the support rod 1. A screw 8 is fixedly connected to the middle of the adjustment knob 7. The end of the screw 8 is rotatably connected to the upper and lower ends of the inner wall of the support rod 1. The adjustment assembly also includes a slider 9 slidably connected to the interior of the support rod 1. The middle of the slider 9 is threadedly connected to the outer wall of the screw 8. Multiple grooves are formed on the outer wall of the support rod 1. Multiple fixing ears 10 are fixedly connected to the outer wall of the slider 9 at positions corresponding to the grooves. A connecting rod 11 is rotatably connected to the middle of each fixing ear 10. A fixing ear 12 is rotatably connected to the upper end of the connecting rod 11. The outer end of the fixing ear 12 is fixedly connected to the upper side of the outer wall of the sleeve 3.

[0026] Specifically, rotating the adjustment knob 7 causes the screw 8 to rotate. The two ends of the screw 8 are fixed to the inner wall of the support rod 1, allowing only rotation and not axial movement. The slider 9 is threaded to the screw 8 and moves up or down along the screw 8 during rotation. The fixing lug 10 on the slider 9 is rotatably connected to the fixing lug 12 on the sleeve 3 via the connecting rod 11. When the slider 9 rises, the connecting rod 11 pushes the sleeve 3 outward, increasing the overall height of the support rod 1. Conversely, when the slider 9 falls, the connecting rod 11 pulls the sleeve 3 inward, reducing the height of the bracket for easy storage and carrying.

[0027] Reference Figure 1 , Figure 3 and Figure 4 The lower end of the sleeve 3 is connected to an anti-slip support foot 4 via a telescopic assembly. The telescopic assembly includes an adjustment knob 13 rotatably connected to the lower side of the outer wall of the sleeve 3. A worm gear 14 is fixedly connected to the middle of the adjustment knob 13. A worm wheel 15 is meshed with the outer wall of the worm gear 14. A screw 17 is threadedly connected to the middle of the worm wheel 15. A limit plate 18 is fixedly connected to the upper end of the screw 17. The outer wall of the limit plate 18 is slidably connected to the inner wall of the sleeve 3. The lower end of the screw 17 is fixedly connected to the upper end of the anti-slip support foot 4. Fixing plates 16 are provided on both the upper and lower sides of the worm wheel 15. The outer wall of the fixing plate 16 is fixedly connected to the lower inner side of the sleeve 3. The middle of the fixing plate 16 is threadedly connected to the outer wall of the screw 17.

[0028] Specifically, rotating the adjustment knob 13 drives the worm gear 14 to rotate, and the worm gear 14 meshes with the worm wheel 15, causing the worm wheel 15 to rotate. The worm wheel 15 is threadedly connected to the screw 17, and the screw 17 moves up and down under the action of the worm wheel 15, thereby driving the anti-slip support foot 4 to extend and retract. The fixing plate 16 ensures the stability of the worm wheel 15 when it rotates, and the limiting plate 18 prevents the screw 17 from coming out. Under different ground conditions, the overall balance of the bracket can be adjusted by extending and retracting the anti-slip support foot 4, increasing the friction with the ground and making the fan less likely to tip over during use.

[0029] Reference Figure 1 and Figure 5 An adjusting seat 5 is installed at the upper end of the support rod 1. An installation block 6 is connected to the interior of the adjusting seat 5 via a rotating assembly. The rotating assembly includes an adjusting knob 19 rotatably connected to the front end of the adjusting seat 5. A rotating shaft 20 is fixedly connected to the middle of the adjusting knob 19. A chuck 21 is fixedly connected to the front side of the outer wall of the rotating shaft 20. A cavity is provided at the front end of the adjusting seat 5. The rear end of the chuck 21 is rotatably connected to the rear end inside the cavity. The rear side of the outer wall of the rotating shaft 20 is fixedly connected to the lower part of the installation block 6. The rear end of the rotating shaft 20 rotates... A fixed rod 23 is fixedly connected to the inner rear end of the adjusting seat 5. A locking rod 22 is rotatably connected to the lower end of the fixed rod 23. The left end of the locking rod 22 is engaged with the outer wall of the chuck 21. A tension spring 24 is fixedly connected to the upper end of the locking rod 22. The upper end of the tension spring 24 is fixedly connected to the upper left side of the fixed rod 23. An L-shaped rod 25 is rotatably connected to the lower left side of the locking rod 22. A fixed shaft 26 is rotatably connected to the middle of the L-shaped rod 25. The rear end of the fixed shaft 26 is fixedly connected to the rear end of the empty chamber.

[0030] Specifically, the adjusting seat 5 is installed on the upper end of the support rod 1. Then, the L-shaped rod 25 is pushed upwards. The left end of the L-shaped rod 25 pulls the left end of the locking rod 22 downwards, causing the left end of the locking rod 22 to disengage from the chuck 21. Then, the adjusting knob 3 19 is rotated, which drives the rotating shaft 20 and the chuck 21 to rotate, thereby adjusting the fan installed on the mounting block 6 to a suitable angle. Then, the L-shaped rod 25 is released. Under the action of the tension spring 24, the locking rod 22 re-locks the chuck 21, thus fixing the fan on the mounting block 6. By fixing the fan angle, it is convenient for users to accurately blow air to different positions, thereby meeting diverse usage scenarios.

[0031] Working principle: In use, first turn the adjustment knob 7 to drive the screw 8 to rotate. The screw 8 drives the slider 9 to slide up and down inside the support rod 1. The fixing lug 10 on the slider 9 is connected to the fixing lug 12 on the sleeve 3 through the connecting rod 11, thereby adjusting the angle of the sleeve 3. Then, depending on the ground conditions, turn the adjustment knob 13 to drive the worm 14 to rotate. The worm 14 meshes with the worm wheel 15, causing the worm wheel 15 to rotate. The screw 17 is threadedly engaged with the worm wheel 15. When the worm wheel 15 rotates, the screw 17 moves up and down axially, thereby driving the anti-slip support foot 4 to extend and retract. When the anti-slip support foot 4 extends to the appropriate height, stop turning the adjustment knob 13, and then install the adjustment seat 5. At the upper end of the support rod 1, the fan is fixedly installed on the mounting block 6. Depending on the required blowing angle, the L-shaped rod 25 is pushed upwards. The L-shaped rod 25 drives the locking rod 22 to disengage from the chuck 21. Then, the adjustment knob 3 19 is rotated, which drives the rotating shaft 20 and the chuck 21 to rotate, thereby driving the mounting block 6 and the fan to rotate to the appropriate angle. The L-shaped rod 25 is released, and the locking rod 22, under the action of the tension spring 24, re-fixes the chuck 21, thus fixing the fan. When it is necessary to carry it, the fan and the adjustment seat 5 can be removed. Then, the adjustment knob 1 7 and the adjustment knob 2 13 are rotated in the opposite direction to fold the sleeve 3 and retract the anti-slip support foot 4, so as to facilitate the storage of the adjustment seat 5 and the support rod 1.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
