DETAILED DESCRIPTION

[0033] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0034] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make non-creative modifications to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.

[0035] Embodiment 1:

[0036] This embodiment relates to a folding device with telescopic and storage functions, which is mainly used for electronic equipment or small electrical equipment (such as fans, desk lamps, etc.). Figure 1-4 As shown, the folding device includes: a chassis 1 and a telescopic mechanism 2.

[0037] The chassis 1 is used to support electronic equipment or small electrical equipment. One end of the telescopic mechanism 2 is assembled with the chassis 1, and the other end is assembled with the electronic equipment or small electrical equipment. When in use, the telescopic mechanism 2 can be extended to adjust the support height; when stored, the telescopic mechanism 2 can be retracted and accommodated in the chassis 1.

[0038] It should be noted that if Figure 1-4 As shown, a storage slot 3 is provided on the chassis 1, and the telescopic mechanism 2 is rotatably installed in the storage slot 3, and a locking mechanism 4 is provided between the telescopic mechanism 2 and the storage slot 3. When the telescopic mechanism 2 is in use, the locking mechanism 4 is used to lock the telescopic mechanism 2 with the chassis 1; when the telescopic mechanism 2 is stored, the locking mechanism 4 releases the lock between the telescopic mechanism 2 and the chassis 1, and after the lock is released, the telescopic mechanism 2 is flipped relative to the chassis 1 and stored in the storage slot 3.

[0039] Furthermore, if Figure 1-4 As shown, the telescopic mechanism 2 includes: an inner sleeve 5 and a telescopic rod. The hinged end of the inner sleeve 5 is rotatably assembled with the chassis 1. The fixed end of the telescopic rod is sleeved in the inner sleeve 5 and fixedly assembled with the inner sleeve 5. The telescopic end of the telescopic rod is assembled with the electronic device or small electrical equipment.

[0040] Specifically, both sides of the hinged end of the inner sleeve 5 extend outward to form a rotating shaft 11, and the two rotating shafts 11 are arranged on the same axis. The chassis 1 is provided with an accommodating space 9, and a mounting boss 10 is provided on the inner wall surface of one side of the accommodating space 9. The mounting boss 10 is provided with mounting shaft holes 25 at positions corresponding to the two rotating shafts 11. The size of the mounting shaft hole 25 is adapted to the size of the two rotating shafts 11, and the two rotating shafts 11 are respectively inserted into the mounting shaft holes 25, so that the inner sleeve 5 can be rotatably mounted on the mounting boss 10 through the rotating shaft 11.

[0041] The locking mechanism 4 includes a locking member 6, an outer sleeve 7 and a limiting structure 13. The outer sleeve 7 is sleeved on the inner sleeve 5 and can rotate relative to the inner sleeve 5 to lock or unlock the inner sleeve 5 and the chassis 1. The limiting structure 13 is arranged between the inner sleeve 5 and the outer sleeve 7, and the limiting structure 13 is used to limit the outer sleeve 7 to move on the inner sleeve 5. The locking member 6 is sleeved on the inner sleeve 5 and is located at the hinged end of the inner sleeve 5.

[0042] It should be noted that when the outer sleeve 7 rotates relative to the inner sleeve 5 and approaches the chassis 1, the outer sleeve 7 presses the locking piece 6 against the chassis 1 to lock the inner sleeve 5; when the outer sleeve 7 rotates relative to the inner sleeve 5 and moves away from the chassis 1, the outer sleeve 7 releases the pressure on the locking piece 6 to release the lock of the inner sleeve 5.

[0043] Specifically, Figure 1-4 As shown, the outer surface of the inner sleeve 5 is provided with an outer thread 8, and the inner surface of the outer sleeve 7 is provided with a corresponding inner thread. The outer sleeve 7 can be locked and fixed on the inner sleeve 5 through a threaded structure that cooperates with the inner sleeve 5. Since the locking member 6 is sleeved on the inner sleeve 5, when the outer sleeve 7 drives the locking member 6 to press against the mounting boss 10, the outer sleeve 7, the inner sleeve 5 and the telescopic rod are all fixed relative to the chassis 1.

[0044] Preferably, if Figure 1-4As shown, the outer circumference of the rotating shaft 11 is also sleeved with a damping gasket 12 for increasing friction, and the damping gasket 12 is clamped between the rotating shaft 11 and the mounting shaft hole 25 of the mounting boss 10.

[0045] like Figure 1-4 As shown, the limiting structure 13 includes: a clamping ring 14 and a locking ring 15. The clamping ring 14 is sleeved on the inner sleeve 5 at a side away from the hinged end, and the clamping ring 14 is clamped and assembled with the inner sleeve 5 and is provided with an opening 16. A part of the locking ring 15 passes through the opening 16 of the clamping ring 14 and is plugged into the inner sleeve 5, and the other part is clamped and assembled with the clamping ring 14.

[0046] Specifically, Figure 1-4 As shown, a first locking hole 17 and a slot 18 are provided at the upper end of the inner sleeve 5, and a first locking block 19 is provided on the clamping ring 14. When the clamping ring 14 is assembled with the inner sleeve 5, the first locking block 19 is assembled with the first locking hole 17 to achieve the assembly between the clamping ring 14 and the inner sleeve 5. A second locking hole 20 is provided on the clamping ring 14, and a second locking block 21 and an insert block 22 are protrudingly provided on the inner wall of the lock ring 15. When the lock ring 15 is assembled with the clamping ring 14, the insert block 22 first passes through the opening 16 and cooperates with the slot 18, and then the second locking block 21 cooperates with the second locking hole 20 to achieve the assembly between the lock ring 15 and the clamping ring 14.

[0047] Preferably, if Figure 1-4 As shown, an arc-shaped groove 23 is provided on the telescopic rod, and an arc-shaped protrusion 24 is provided on the locking ring 15. Through the cooperation between the arc-shaped protrusion 24 and the arc-shaped groove 23, the telescopic rod and the locking ring 15 are tightly matched. Since the locking ring 15 is tightly matched with the inner sleeve 5 through the clamping ring 14, the tight assembly between the telescopic rod and the inner sleeve 5 is guaranteed.

[0048] The working principle of this embodiment is roughly as follows: when opening the folding device, the telescopic rod is first pulled obliquely upward by external force, so that the telescopic rod drives the inner sleeve 5, the outer sleeve 7, the limiting structure 13 and the locking member to flip upward around the rotating shaft 11 until the telescopic rod is perpendicular to the chassis 1, and then the outer sleeve 7 is rotated so that the outer sleeve 7 drives the locking member 6 to press against the mounting boss 10, thereby locking the telescopic rod in a vertical position, completing the opening of the folding device. It has the advantages of easy folding, easy storage, good portability, simple folding operation, saving packaging materials and packaging volume, and saving transportation costs.

[0049] Embodiment 2:

[0050] The main difference between this embodiment and embodiment 1 is that Figure 5 , 6 As shown, in this embodiment,

[0051] The locking mechanism 4 includes: a fixed head 28, a fixed plate 29, an adjusting bolt 30 and an adjusting plate 31. An assembly cavity 32 is provided on the rotating shaft 11, and the fixed head 28 is fixedly assembled in the assembly cavity 32 and can move synchronously with the rotating shaft 11. One end of the fixed plate 29 is fixedly mounted on the chassis 1, and the fixed plate 29 is used to fix the other end of the damper on the chassis 1. The adjusting plate 31 is arranged between the fixed plate 29 and the fixed head 28, and / or between the fixed plate 29 and the adjusting bolt 30. The adjusting bolt 30 passes through the adjusting plate 31, and the fixed plate 29 and the fixed head 28 are threadedly assembled. The adjusting bolt 30 is used to adjust the friction between the fixed plate 29 and the fixed head 28.

[0052] In this embodiment, two adjusting plates 31 are provided, wherein one plate is located between the fixing plate 29 and the fixing head 28 , and the other plate is located between the fixing plate 29 and the adjusting bolt 30 .

[0053] Preferably, a mounting platform is provided on the inner side wall of the chassis 1 near the receiving slot 3, and the fixing plate 29 is fixedly mounted on the mounting platform by two fastening screws. A wire hole is provided at the other end of the rotating shaft 11, and the wire hole is used for passing the spring wire in the telescopic rod.

[0054] Embodiment 3:

[0055] The main difference between this embodiment and the embodiment and embodiment 2 is that Figure 7 , 8 As shown, in this embodiment, the locking mechanism 4 is a combination of embodiment 1 and embodiment 2. The locking mechanism 4 configured in this way can not only effectively ensure the stability of the telescopic rod when it is fixed, but also effectively improve the feel of the folding device when the telescopic rod is rotated, thereby improving the user experience.

[0056] Embodiment 4:

[0057] This embodiment relates to a foldable fan, such as Figure 1-9 As shown, the foldable fan includes: a folding device, a fan body 33 and a flip locking mechanism 34.

[0058] The folding device is any one of Embodiment 1, Embodiment 2, and Embodiment 3. The fan body 33 is arranged on the side of the folding device away from the chassis 1. One end of the flip locking mechanism 34 is assembled with the fan body 33, and the other end is assembled with the side of the folding device away from the chassis 1. When the fan body 33 is in use, the flip locking mechanism 34 is used to achieve locking between the fan body 33 and the folding device; when the fan body is stored, the flip locking mechanism 34 is used to achieve rotation between the fan body 33 and the folding device.

[0059] Specifically, the fan body 33 includes: a face mask 35, a rear cover 36, a motor 37, and fan blades 38. After the face mask 35 and the rear cover 36 are closed, a receiving cavity for accommodating the motor 37 and the fan blades 38 is formed. The motor 37 is fixedly arranged in the rear cover 36, and the fan blades 38 are fixedly connected to the output shaft of the motor 37. This part of the fan body 33 is prior art and not the focus of protection of the present invention, so it will not be elaborated here one by one.

[0060] Preferably, an operation button 39 is arranged on the chassis 1. The end face of the chassis 1 where the operation button 39 is arranged is the operation surface, and the storage groove 3 is arranged on the operation surface. When the fan body 33 is folded, the locking mechanism 4 and the flipping locking mechanism 34 are accommodated in the storage groove 3 after being flipped and folded.

[0061] Furthermore, the flipping locking mechanism 34 includes: a connecting seat 40, a pan head 41, a hinge 42, and a damping rubber ring 43.

[0062] The connecting seat 40 is fixedly installed on the back of the fan body 33. The pan head 41 is fixedly installed on the side of the locking mechanism 4 away from the chassis 1, and the pan head 41 is used for assembling with the connecting seat 40. One end of the hinge 42 is assembled with the connecting seat 40 and the other end is assembled with the pan head 41. The hinge 42 is used to realize the rotational assembly between the pan head 41 and the connecting seat 40. The damping rubber ring 43 is arranged between the hinge 42 and the pan head 41, and the damping rubber ring 43 is used to lock the fan body 33 after flipping.

[0063] Specifically, a notch 44 with a "C" - shaped structure is arranged on the connecting seat 40. There are two hinges 42, and the two hinges 42 are respectively installed on the opposite inner wall surfaces of the notch 44. One end of the pan head 41 is circular - ring - shaped and is hinged between the two hinges 42, and the other end of the pan head 41 is fixedly assembled with the locking mechanism 4.

[0064] Among them, the damping rubber ring 43 is arranged at the hinge between the pan head 41 and the two hinges 42. A circular through - hole 45 is opened at the upper end of the pan head 41, and circular protrusions 46 are arranged on the sides of the two hinges 42 relative to the circular through - hole 45. The two circular protrusions 46 correspond to the circular through - hole 45 one by one. The damping rubber ring 43 is clamped between the outer wall surface of the circular protrusion 46 and the inner wall surface of the circular through - hole 45 and is in an interference fit. That is, the two damping rubber rings 43 are used to increase the radial friction when the pan head 41 rotates relative to the two hinges 42, so as to ensure that the fan body 33 can maintain the state after rotation.

[0065] When the fan body 33 is stored, the fan body 33 can be horizontally flipped and folded through the flip locking mechanism 34. Moreover, when the fan body 33 is unfolded for use, the fan body 33 can be flipped on the pan head 41 through the connecting seat 40 connected thereto, and the air supply angle of the fan body 33 can be adjusted through the damping rubber ring 43, thereby realizing the multi-angle adjustment function of the fan body 33.

[0066] After adopting the above technical solution, by providing a flip locking mechanism 34 on the fan body 33, the fan body 33 can realize the functions of flipping, folding and multi-angle adjustment through the flip locking mechanism 34. In addition, the fan body 33 is also connected to a locking mechanism 4, and the telescopic locking function can be realized through the locking mechanism 4. The structure of the present invention is simple and compact, and the fan body 33 can be folded and folded on the chassis 1 through the flip locking mechanism 34 and the locking mechanism 4. The folded fan becomes smaller, does not take up space, and is easy to store and convenient to carry.

[0067] The above is only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
