Abstract
Description
Technical Field
[0001] This utility model relates to the field of turbine fan technology, specifically to a turbine fan with an adjustable air outlet position. Background Technology
[0002] Turbo fans, with their high airflow and high air pressure, are widely used in air-cooled heatsinks for all-in-one PCs and desktop computers. The position of the exhaust port (i.e., the length of the exhaust duct) of a conventional turbo fan is not adjustable. To meet system layout and cooling requirements, additional airflow structures are typically added to match or fill the gap between the turbo fan's exhaust port and the heatsink's intake port. These additional airflow structures increase the workload of equipment assembly. Furthermore, the use of injection molding to produce these airflow structures also increases the overall cost of the equipment.
[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0005] To achieve the above objectives, a turbine fan with an adjustable air outlet position is provided, comprising:
[0006] The fan body has an exhaust port.
[0007] The duct assembly includes a rectangular insert sleeve and a socket sleeve, one end of the insert sleeve being connected to the exhaust port, and the other end of the insert sleeve being movably inserted into one end of the socket sleeve.
[0008] The locking structure includes a plurality of first elastic racks and a plurality of second elastic racks. The plurality of first elastic racks are respectively formed on the outer walls of opposite sides of the insertion sleeve. The plurality of first elastic racks are spaced apart along the axial direction of the insertion sleeve. The plurality of second elastic racks are respectively formed on the inner walls of opposite sides of the insertion sleeve. The plurality of second elastic racks are arranged along the axial direction of the socket sleeve. The first elastic racks and the second elastic racks are arranged in the same direction. The plurality of first elastic racks engage with the plurality of second elastic racks.
[0009] Furthermore, the first elastic rack has a root near the insertion sleeve and a head away from the insertion sleeve, the width of the first elastic rack gradually decreases from the root to the head, and the shape of the second elastic rack is adapted to the shape of the first elastic rack.
[0010] Furthermore, the cross-section of the first elastic rack is an isosceles triangle.
[0011] Furthermore, the cross-section of the first elastic rack is an isosceles trapezoid.
[0012] Furthermore, the first elastic rack and the second elastic rack are plastic racks.
[0013] The beneficial effects of this utility model are as follows: In the turbine fan with adjustable air outlet position, the insertion depth of the insertion sleeve in the socket sleeve is adjusted by pushing and pulling the socket sleeve of the air duct assembly, thereby adjusting the position of the air outlet of the air duct assembly. On the other hand, by designing a locking structure on the left and right side walls of the air outlet of the air duct assembly of the turbine fan, the length of the air duct assembly is locked by the engagement of the first elastic rack and the second elastic rack of the locking structure, thereby fixing the position of the air outlet of the air duct assembly and achieving the purpose of extending and retracting the length of the air outlet.
[0014] This utility model's adjustable air outlet turbine fan achieves adjustable air outlet position without adding external structural components, effectively reducing equipment assembly steps and avoiding the mold costs associated with injection molding parts, thus benefiting both production efficiency and cost.

[0022] Reference Figures 1 to 4 As shown, this utility model provides a turbine fan with an adjustable air outlet position, including: a fan body 1, an air duct assembly 2, and a locking structure.
[0023] The fan body 1 has an exhaust port. In this embodiment, the fan body 1 is a turbine fan. The turbine fan housing has an exhaust port.
[0024] The duct assembly 2 includes a plug sleeve 21 and a socket sleeve 22. Both the plug sleeve 21 and the socket sleeve 22 are rectangular sleeves. The cross-sections of both the plug sleeve 21 and the socket sleeve 22 are rectangular.
[0025] One end of the insert sleeve 21 is connected to the exhaust port. The other end of the insert sleeve 21 is movably inserted into one end of the socket sleeve 22. The other end of the socket sleeve is the exhaust port of the turbine fan with adjustable exhaust port position according to this invention. By adjusting the insertion depth of the insert sleeve in the socket sleeve, the length of the duct assembly is adjusted, thereby adjusting the position of the turbine fan's exhaust port.
[0026] In this embodiment, the locking structure is used to lock the length of the duct assembly, thereby fixing the position of the turbine fan's outlet.
[0027] Specifically, the locking structure includes a plurality of first elastic racks 31 and a plurality of second elastic racks 32.
[0028] Multiple first elastic racks 31 are formed on the outer walls of opposite sides of the insertion sleeve 21. The multiple first elastic racks 31 are spaced apart along the axial direction of the insertion sleeve 21. Multiple second elastic racks 32 are formed on the inner walls of opposite sides of the insertion sleeve 21. The multiple second elastic racks 32 are arranged along the axial direction of the receiving sleeve 22. The first elastic racks 31 and the second elastic racks 32 are arranged in the same direction. The multiple first elastic racks 31 engage with the multiple second elastic racks 32.
[0029] In this embodiment, the insertion sleeve has two opposing outer surfaces in its width direction. A plurality of first elastic racks form first grooves on the two opposing outer surfaces of the insertion sleeve. The first grooves are arranged along the length direction of the insertion sleeve. Each first elastic rack constituting the first groove is arranged along the thickness direction of the insertion sleeve, that is, the first elastic racks are arranged along the width direction of the two opposing outer surfaces of the insertion sleeve, and the plurality of first elastic racks are spaced apart along the length direction of the two opposing outer surfaces of the insertion sleeve.
[0030] Corresponding to the insertion sleeve, the socket sleeve has two opposing inner surfaces in its width direction. A plurality of second elastic racks form second grooves on the two opposing inner surfaces of the socket sleeve. The second grooves are arranged along the length direction of the socket sleeve. Each second elastic rack constituting the second groove is arranged along the thickness direction of the socket sleeve, that is, the second elastic racks are arranged along the width direction of the two opposing inner surfaces of the socket sleeve, and the plurality of second elastic racks are spaced apart along the length direction of the two opposing inner surfaces of the insertion sleeve.
[0031] The locking structure locks the relative positions of the insertion sleeve and the socket sleeve by engaging the first and second grooves, thereby fixing the length of the duct assembly.
[0032] In a preferred embodiment, the first elastic rack 31 has a root portion near the insertion sleeve 21 and a head portion away from the insertion sleeve 21. The width of the first elastic rack 31 gradually decreases from the root portion to the head portion. The shape of the second elastic rack 32 is adapted to the shape of the first elastic rack 31.
[0033] In some embodiments, the cross-section of the first elastic rack 31 is an isosceles triangle.

[0036] In the turbine fan with adjustable air outlet position of this utility model, the insertion depth of the insertion sleeve in the socket sleeve is adjusted by pushing and pulling the socket sleeve of the air duct assembly, thereby adjusting the position of the air outlet of the air duct assembly. On the other hand, by designing a locking structure on the left and right side walls of the air outlet of the air duct assembly of the turbine fan, the length of the air duct assembly is locked by the engagement of the first elastic rack and the second elastic rack of the locking structure, thereby fixing the position of the air outlet of the air duct assembly and achieving the purpose of extending and retracting the length of the air outlet.
[0037] In the turbine fan with adjustable air outlet position of this utility model, the elastic racks on the plug sleeve and socket sleeve of the duct assembly are isosceles trapezoidal or isosceles triangular teeth. The length of the socket sleeve is greater than the length of the plug sleeve, with appropriate fitting tolerances reserved. During the pushing and pulling of the socket sleeve, sliding is achieved through the inclined surface of the isosceles trapezoidal or isosceles triangular shape. During sliding, the meshing between the elastic teeth of the plastic is utilized, thereby enabling the adjustment of the air outlet position of the turbine fan.
[0038] This utility model's adjustable air outlet turbine fan achieves adjustable air outlet position without adding external structural components, effectively reducing equipment assembly steps and avoiding the mold costs associated with injection molding parts, thus benefiting both production efficiency and cost.
