Description

Technical Field

[0001] The present invention relates to the technical field of fans, and in particular to a supporting structure and a vertical electric fan. Background Art

[0002] Circulation fan is a special type of household fan. Compared with traditional fans, circulation fan has unique functions and characteristics. Its main function is not to directly blow air to cool the human body, but to stir the indoor air through strong wind force, accelerate the air circulation flow, and make the temperature of different areas in the room more uniform.

[0003] Many types of circulating fans are now height-adjustable, usually by bolt-locking the telescopic rod. The bolts need to be exposed on the exterior, and the shape is abrupt, affecting the consistency of the overall appearance of the circulating fan. In addition, when adjusting the height, it is necessary to rotate vigorously to achieve positioning. If the bolts are not tightened, there is a risk of positioning failure. Some circulating fans also need to be positioned by internal spring buckles when adjusting the height. It is necessary to press the small bumps to release the restrictive relationship between the support rod and the sleeve mounted on the outside of the support rod. Because the contact area between the small bumps and the hand is small, it causes pain in the hand when pressing, which is a poor experience. In addition, this adjustment method can only adjust the fan to a pre-set position, and there is no way to adjust it according to the actual needs of the user.

[0004] Therefore, the lifting scheme in the prior art has a contradiction between reliable positioning and stepless lifting, and the existing lifting scheme requires strong rotation or convex point pressing, which is inconvenient to operate and destroys the appearance. Summary of the invention

When the adjusting component is in the locking position, the first matching portion is connected to the second matching portion so that the first support member and the second support member are relatively fixed; when the adjusting component is in the unlocking position, the first matching portion and the second matching portion are separated so that the first support member and the second support member are relatively movable to adjust the height of the first support member.

[0011] Furthermore, the first support member is elliptical, the second support member is circular, and the second support member is sleeved on the outside of the first support member; and / or the first matching portion and the second matching portion are respectively an internal thread and an external thread of threaded matching.

[0012] Furthermore, the adjusting component is rotatably arranged on the second supporting member, a limiting protrusion is arranged on the adjusting component, a limiting groove is arranged on the second supporting member, and the limiting protrusion is rotatably limited in the limiting groove; wherein, the first matching portion is arranged on the limiting protrusion, and the second matching portion is arranged on the first supporting member.

[0013] Furthermore, the adjusting component is sleeved on the first support member, the first matching portion is an internal thread arranged on the limiting protrusion facing the first support member, and the second matching portion is an external thread arranged on the first support member.

[0014] Furthermore, there are multiple limiting protrusions and limiting grooves, and the multiple limiting protrusions and limiting grooves are arranged in one-to-one correspondence.

[0015] Further, a first clamping protrusion is provided on the inner wall of the limiting groove, and a first clamping groove matching with the first clamping protrusion is provided on the limiting protrusion, so that when the limiting protrusion moves to connect with the first matching portion and the second matching portion, the first clamping protrusion is clamped into the first clamping groove, so that the adjustment component is limited in the locking position; and / or

[0016] A second clamping protrusion is arranged on the inner wall of the limiting groove, and a second clamping groove matching with the second clamping protrusion is arranged on the limiting protrusion, so that when the limiting protrusion moves to the point where the first matching part and the second matching part are disengaged, the second clamping protrusion is clamped into the second clamping groove to limit the adjustment component to the unlocked position.

[0017] Furthermore, the adjusting component includes a main ring body, a limiting protrusion is arranged on the main ring body and protrudes from one end of the main ring body; an annular limiting portion is arranged on the inner wall of the main ring body;

[0018] The supporting structure also includes:

[0019] An annular cover plate, which is arranged in the main ring body and abuts against the annular limiting portion;

[0020] The fastening component passes through the annular cover plate and is connected to the second support member to fasten the annular cover plate.

[0021] Furthermore, the second support member is tubular, and the main ring body further comprises:

[0022] A first ring body portion, the diameter of which is smaller than the diameter of the inner wall of the second support member, and the limiting protrusion is arranged on the first ring body portion; the first ring body portion is located on the inner side of the second support member;

[0024] Furthermore, the first support member is a bellows having an external thread, the second matching portion is an external thread provided on the first support member, and the first matching portion is an internal thread provided on the adjusting component and facing the first support member and engageable with the external thread.

[0025] According to another aspect of the present invention, a vertical electric fan is provided, comprising a support structure and a fan head mounted thereon, wherein the support structure is the support structure described above.

[0026] By applying the technical solution of the present invention, during use, when it is necessary to adjust the height of the bottom of the second support member relative to the ground, the adjusting component can be manually rotated to move the adjusting component to the unlocked position, so that the first matching portion is separated from the second matching portion, and the lock between the first support member and the second support member is released. Therefore, the second support member can be moved in the vertical direction to achieve the change of the distance between the bottom of the second support member and the ground. When the second support member moves to the preset position, the adjusting component can be adjusted in the reverse direction to gradually move the adjusting component from the unlocked position to the locked position, so that the first matching portion and the second matching portion are connected to each other, so that the first support member and the second support member are relatively fixed to avoid the first support member or the second support member from moving in the vertical direction during normal use.

[0027] Compared with the prior art, through the technical solution of the present application, compared with the prior art, when adjusting the height, there is no need to manually press the protrusions, nor is there any need to manually rotate the locking bolt for adjustment. It is only necessary to rotate the position of the adjusting component to make the adjusting component switch between the unlocked position and the locked position. During the switching of the position of the adjusting component, the first matching portion and the second matching portion switch between a matched and separated state. In this way, the height of the second support member relative to the ground can be adjusted, and the height of the second support member relative to the ground can be adjusted according to the needs of the user. In the prior art, it can only be adjusted to a fixed position, and when adjusting, the prior art also needs to press the small protrusions. The user will feel a strong pain when using it, which affects the customer's experience. In addition, in this way, the internal spring buckle may fail. When the user is adjusting, the internal spring buckle cannot be used normally, which may cause the circulation fan to fail to perform its normal function, and even the circulation fan may be damaged. , what's worse, it may cause certain harm to the user's body. In addition, in the prior art, it is also necessary to rotate the bolts and use the tightening force of the bolts to fix the circulation fan at a preset height. During use, the user needs to exert great force to rotate the bolts. If the bolts are not tightened, the height of the circulation fan cannot be fixed, which will also affect the user's experience. At the same time, during long-term use, the bolts may be lost or rusted. All of the above will affect the user's user experience. In contrast, in the present application, only a simple adjustment component is used to adjust the height of the second support member relative to the ground, thereby adjusting the height of the entire circulation fan. Compared with the adjustment method of the prior art, it is more convenient and convenient. Moreover, in the case of long-term use, the adjustment component in the present application will not have the above-mentioned problems. When operating, the user only needs to rotate the adjustment component around the axis of the first support member or the second support member. It does not require much force, and there will be no problem that the height of the circulation fan cannot be adjusted.

[0028] The present application can adjust the height of the circulation fan through a simple structure. At the same time, the technical solution provided by the present application can meet the requirements of reliable positioning, and the adjustment range of the second support member relative to the ground is longer. In the prior art, it can only be adjusted to a fixed position set in advance, but the present application will not be affected by this and can be adjusted in multiple positions. Compared with the prior art, it greatly meets the needs of users, and the overall appearance is more beautiful than the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0044] The circulation fan is an important component of household fans. Many types of circulation fans are now height-adjustable, usually by bolt-locking the telescopic rod. The bolts need to be exposed on the exterior, and the shape is abrupt, affecting the consistency of the overall appearance of the circulation fan. In addition, when adjusting the height, it is necessary to rotate vigorously to achieve positioning. If the bolts are not tightened, there is a risk of positioning failure. Some circulation fans also need to be positioned by internal spring buckles when adjusting the height. The small bumps need to be pressed to release the restrictive relationship between the sleeve and the internal bellows. Because the contact area between the small bumps and the hand is small, it causes pain in the hand when pressed, which is a poor experience. In addition, this adjustment method can only adjust the fan to a pre-set position, and there is no way to adjust it according to the actual needs of the user.

[0045] Therefore, the lifting scheme in the prior art has a contradiction between reliable positioning and stepless lifting, and the existing lifting scheme requires strong rotation or convex point pressing, which is inconvenient to operate and destroys the appearance.

[0046] Therefore, the purpose of this application is to provide a support structure and a vertical electric fan to address the above problems.

[0047] Firstly, the present application provides a support structure, the support structure comprising: a first support member 1;

[0048] A second support member 2, wherein the top of the first support member 1 is located below the second support member 2, and the top of the first support member 1 is detachably connected to the bottom of the second support member 2;

[0049] An adjusting component 15, on which a first matching portion 3 is disposed, the adjusting component 15 can be disposed on the first supporting member 1 or the second supporting member 2, the other of the first supporting member 1 and the second supporting member 2 is provided with a second matching portion 4, and the first matching portion 3 and the second matching portion 4 are matched and disposed;

[0050] Among them, the position of the adjusting component 15 is adjustable so as to move to a locking position or an unlocking position. When the adjusting component 15 is in the locking position, the first matching portion 3 is connected to the second matching portion 4 so that the first support member 1 and the second support member 2 are relatively fixed; when the adjusting component 15 is in the unlocking position, the first matching portion 3 and the second matching portion 4 are separated so that the first support member 1 and the second support member 2 are relatively movable so as to adjust the height of the first support member 1.

[0051] Specifically, Figures 1 to 9 As shown, the present application provides a support structure, which includes a first support member 1, a second support member 2 is provided above the first support member 1, and the top of the first support member 1 is detachably connected to the bottom of the second support member 2, and the support structure also includes an adjusting component 15, which can be arranged on any one of the first support member 1 and the second support member 2, a first matching portion 3 is arranged on the adjusting component 15, and the second matching portion 4 is arranged on the other of the first support member 1 and the second support member 2, and the first matching portion 3 can be used in conjunction with the second matching portion 4, wherein the adjusting component 15 is adjustably arranged, and the adjusting component 15 can move to a locking position or an unlocking position, when the adjusting component 15 moves to the locking position, the first matching portion 3 is connected to the second matching portion 4, so that the positions of the first support member 1 and the second support member 2 are relatively fixed, and when the adjusting component 15 moves to the unlocking position, the first matching portion 3 is separated from the second matching portion 4, so that the first support member 1 and the second support member 2 can move relative to each other in the vertical direction, thereby adjusting the height of the first support member 1.

[0052] During use, when the height of the second support member 2 needs to be adjusted, the adjusting component 15 can be moved to the unlocking position, so that the first matching portion 3 is separated from the second matching portion 4, and the lock between the first support member 1 and the second support member 2 is released, so that the second support member 2 can be moved in the vertical direction. When the second support member 2 moves to the preset position, the adjusting component 15 can be moved to the locking position again, and the first matching portion 3 and the second matching portion 4 are connected to each other, so that the first support member 1 and the second support member 2 are relatively fixed to prevent the first support member 1 or the second support member 2 from moving in the vertical direction.

[0053] Compared with the prior art, through the technical solution of the present application, when adjusting the height, there is no need to press the protrusions, nor is there a need to adjust by means of locking bolts. Only the position of the adjusting component 15 needs to be adjusted to achieve the height adjustment of the second support member 2, and the height of the second support member 2 can be adjusted according to the needs of the user, while in the prior art, it can only be adjusted to a fixed position. The technical solution provided by the present application does not have the contradiction between reliable positioning and stepless lifting, and the operation is more convenient than the prior art, and the overall appearance is more beautiful.

[0054] In this embodiment, the first support member 1 is elliptical, the second support member 2 is circular, and the second support member 2 is sleeved on the outside of the first support member 1; and / or the first matching portion 3 and the second matching portion 4 are respectively an internal thread and an external thread of threaded matching.

[0055] Specifically, Figure 3 , Figure 4 As shown, the first support member 1 in the embodiment of the present application is elliptical, the second support member 2 is circular, and the second support member 2 is sleeved on the outside of the first support member 1, the first matching portion 3 is an internal thread, and the second matching portion 4 is an external thread. During use, when the adjustment component 15 is in the locking position, the internal thread and the external thread engage with each other, thereby fixing the first support member 1 and the second support member 2 together to fix the height of the second support member 2.

[0056] In order to achieve the limitation of the adjusting component 15, the adjusting component 15 is rotatably arranged on the second support member 2, a limiting protrusion 5 is arranged on the adjusting component 15, and a limiting groove 6 is arranged on the second support member 2, and the limiting protrusion 5 can be rotatably limited in the limiting groove 6; wherein, the first matching portion 3 is arranged on the limiting protrusion 5, and the second matching portion 4 is arranged on the first support member 1.

[0057] Specifically, Figure 2 and Figure 4 As shown, the adjusting component 15 is rotatably connected to the second support member 2, a limiting protrusion 5 is provided on the adjusting component 15, and a limiting groove 6 is provided on the second support member 2, the limiting protrusion 5 can slide in the limiting groove 6, the limiting groove 6 has a first limiting end and a second limiting end, and the width of the first limiting end is inconsistent with the width of the second limiting end, and the width of the second limiting end is greater than the width of the first limiting end. When the limiting protrusion 5 is at the first limiting end, the adjusting component 15 is in a locked position, and when the limiting protrusion 5 slides to the second limiting end, the adjusting component 15 is in an unlocked position. By rotating the adjusting component 15, the limiting protrusion 5 can be driven to switch between the first limiting end and the second limiting end, thereby fixing or unlocking the positional relationship between the first support member 1 and the second support member 2.

[0058] Through the structure of the present application, the adjusting component 15 can be switched between the locked position and the unlocked position by simply rotating the adjusting component 15 so that the limit protrusion 5 is switched between the first limit end and the second limit end, thereby fixing or unlocking the relative position relationship between the first support member 1 and the second support member 2 to adjust the height of the second support member 2.

[0059] Furthermore, the adjusting component 15 is sleeved on the first supporting member 1 , the first matching portion 3 is an internal thread provided on the limiting protrusion 5 facing the first supporting member 1 , and the second matching portion 4 is an external thread provided on the first supporting member 1 .

[0060] Specifically, the adjustment component 15 is partially sleeved on the first support member 1, wherein the first matching portion 3 is arranged on the limiting protrusion 5 and faces the internal thread on the first support member 1, and the second matching portion 4 is arranged on the first support member 1 and faces the external thread on the second support member 2, and the internal thread and the external thread can be engaged with each other or relatively separated.

[0061] Example 1

[0062] Specifically, Figure 4 , Fig.10 , Figure 1 As shown, the limiting protrusion 5 and the limiting groove 6 can be set in multiple, and the multiple limiting protrusions 5 correspond to the limiting grooves 6 one by one. In this embodiment, the limiting protrusion 5 and the limiting groove 6 are both set in two, wherein the limiting groove 6 presents an arc-shaped structure, such as Fig.11 As shown, the limiting groove 6 has an inner arc edge and an outer arc edge, and the curvature bending angle of the inner arc edge is consistent with the curvature of the first support member 1, and the curvature angle of the outer arc edge is consistent with the inner side wall of the second support member 2, that is, the inner arc edge fits the outer wall of the first support member 1, and the outer arc edge fits the inner wall of the second support member 2. Therefore, when rotating clockwise or counterclockwise around the axis direction of the second support member 2, the arc groove gradually increases or decreases. When the limiting protrusion 5 is in the locking position, the first side wall of the limiting protrusion 5 (the inner side wall of the limiting protrusion 5) is in contact with the first support member 1. The outer walls are in contact with each other, and the second side wall of the limiting protrusion 5 (the outer side wall of the limiting protrusion 5) is in contact with the inner side wall of the second support member 2. When the limiting protrusion 5 is in the unlocked position, the first side wall of the limiting protrusion 5 is separated from the outer side wall of the first support member 1, and the second side wall of the limiting protrusion 5 is in contact with the inner side wall of the second support member 2. That is, during the rotation of the adjusting component 15, the outer side wall of the limiting protrusion 5 is always in contact with the inner side wall of the second support member 2, and only the inner side wall of the limiting protrusion 5 and the outer wall of the first support member 1 will be engaged or separated.

[0063] Example 2

[0064] Based on Example 1, the support structure of the present application also includes: a first clamping protrusion 7 is provided on the inner wall of the limiting groove 6, and a first clamping groove 8 matching with the first clamping protrusion 7 is provided on the limiting protrusion 5, so that when the limiting protrusion 5 moves to connect with the first matching part 3 and the second matching part 4, the first clamping protrusion 7 is clamped into the first clamping groove 8 to limit the adjustment part 15 in the locking position.

[0065] Specifically, Fig.10 and Fig.11 As shown, a first clamping protrusion 7 is provided on the inner wall of the limiting groove 6, and a first clamping groove 8 is provided on the limiting protrusion 5. The first clamping protrusion 7 and the first clamping groove 8 can be clamped with each other, so that when the limiting protrusion 5 moves to connect the first matching part 3 with the second matching part 4, the first clamping protrusion 7 can be clamped into the first clamping groove 8, and the adjusting component 15 is limited in the locking position to avoid the adjusting component 15 from rotating in case of accidental human contact. By providing the first clamping protrusion 7 and the first clamping groove 8, the rotation of the adjusting component 15 can be further limited to avoid the height of the second support member 2 changing due to the rotation of the adjusting component 15 after the height of the second support member 2 is adjusted.

[0066] Example 3

[0067] The embodiment of the present application further includes, based on the embodiment 1 and the embodiment 2:

[0068] A second clamping protrusion 9 is provided on the inner wall of the limiting groove 6, and a second clamping groove 10 matching with the second clamping protrusion 9 is provided on the limiting protrusion 5, so that when the limiting protrusion 5 moves to the point where the first matching part 3 and the second matching part 4 are disengaged, the second clamping protrusion 9 is clamped into the second clamping groove 10 to limit the adjustment component 15 in the unlocked position.

[0069] Specifically, a second clamping protrusion 9 is further provided on the inner wall of the limiting groove 6, and a second clamping groove 10 which can be engaged with the second clamping protrusion 9 is provided on the limiting protrusion 5, so that when the limiting protrusion 5 moves to the point where the first matching portion 3 and the second matching portion 4 are disengaged from each other, the second clamping protrusion 9 can be clamped into the second clamping groove 10 and limit the position of the adjusting component 15 to the unlocked position to avoid accidental human contact and the rotation of the adjusting component 15, thereby changing the height of the second support member 2. By providing the second clamping protrusion 9 and the second clamping groove 10 again on the basis of Examples 1 and 2, it can be ensured that when the height of the second support member 2 is adjusted, the adjusting component 15 will not rotate to the locked position due to accidental human contact, thereby causing the second support member 2 to become unable to be adjusted.

[0070] Furthermore, the adjusting component 15 includes a main ring body 11, a limiting protrusion 5 is arranged on the main ring body 11 and protrudes from one end of the main ring body 11; an annular limiting portion 12 is arranged on the inner wall of the main ring body 11;

[0071] The supporting structure also includes:

[0072] An annular cover plate 13, which is disposed in the main ring body 11 and abuts against the annular limiting portion 12;

[0073] The fastening component 14 passes through the annular cover plate 13 and is connected to the second support member 2 to fasten the annular cover plate 13 .

[0074] Specifically, Figure 2 As shown, the adjusting component 15 includes a main ring body 11, wherein the limiting protrusion 5 is arranged on the main ring body 11 and protrudes from one end of the main ring body 11, and an annular limiting portion 12 is arranged on the inner wall of the main ring body 11, and the inner diameter of the annular limiting portion 12 is smaller than the inner diameter of the main ring body 11, and the supporting structure also includes an annular cover plate 13 arranged in the main ring body 11 and abutting against the annular limiting portion 12, and also includes a fastening component 14, which is a fastening screw in this embodiment, and is fixed on the annular cover plate 13. A threaded hole is provided on the plate 13, and the fastening component 14 can pass through the annular cover plate 13 through the threaded hole to connect with the second support member 2 to fasten the annular cover plate 13. Because the annular cover plate 13 is arranged in the main ring body 11 and abuts against the annular limiting portion 12, when the annular cover plate 13 is connected to the second support member 2 through the fastening component 14, it can provide axial positioning for the adjusting component 15 to prevent the adjusting component 15 from being separated from the second support member 2 during the rotation process.

[0075] Further, the second support member 2 is tubular, and the main ring body 11 further includes: a first ring body portion 16, the diameter of the first ring body portion 16 is smaller than the diameter of the inner wall of the second support member 2, and the limiting protrusion 5 is provided on the first rotating portion; the first ring body portion 16 is located on the inner side of the second support member 2;

[0076] The second ring body 17 is located on the side of the first ring body 16 away from the limiting protrusion 5 . The diameter of the second ring body 17 is greater than or equal to the diameter of the outer wall of the second support member 2 . The second ring body 17 is located on the outer side of the second support member 2 .

[0077] Specifically, the second support member 2 is tubular, and the main ring body 11 also includes a first ring body portion 16, the diameter of the first ring body portion 16 is smaller than the diameter of the inner wall of the second support member 2, wherein the limiting protrusion 5 is arranged on the first ring body portion 16, and the first ring body portion 16 is on the inner side of the second support member 2, and also includes a second ring body portion 17, the second ring body portion 17 is located on the side of the first ring body portion 16 away from the limiting protrusion 5, and the diameter of the second ring body portion 17 is greater than or equal to the diameter of the outer wall of the second support member 2, and the second ring body portion 17 is located on the outer side of the second support member 2.

[0078] Furthermore, the first support member 1 is a bellows having an external thread, the second matching portion 4 is an external thread provided on the first support member 1, and the first matching portion 3 is an internal thread provided on the adjustment component 15 and facing the first support member 1 and engageable with the external thread.

[0079] Specifically, the first support member 1 is an elliptical corrugated tube, and the first support member 1 is a telescopic inner tube, the second matching portion 4 is an external thread arranged on the first support member 1, and the first matching portion 3 is an internal thread arranged on the adjusting component 15, and facing the first support member 1, and can be engaged with the external thread. The first support member 1 can be connected to the chassis assembly below to support the whole. The first support member 1 can be telescopic in the second support member 2 to adjust the height of the second support member 2 relative to the ground, thereby adjusting the overall height of the fan.

[0080] The present application further provides a vertical electric fan based on the above-mentioned embodiments. The vertical electric fan includes the above-mentioned supporting structure and a fan head installed on the supporting structure.
