Description

Technical Field

[0001] The utility model relates to the technical field of fans, and in particular, to a support structure and a vertical electric fan. Background Art

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

[0003] The heights of many current circulation fans are adjustable, generally by the way of bolt-locking telescopic rods. The bolts need to be exposed on the appearance, with a protruding shape, which affects the consistency of the overall appearance of the circulation fan. And when adjusting the height, a large force is required to rotate to achieve positioning. If the bolts are not tightened, there is a risk of positioning failure. There are also some circulation fans that need to be positioned by internal spring catches when adjusting the height. It is necessary to press small bumps to release the limiting relationship between the support rod and the sleeve sleeved outside the support rod. Because the contact area between the small bumps and the hand is small, it will cause pain in the hand when pressing, with a poor experience. And this adjustment method can only adjust the fan to a pre-set position and cannot be adjusted according to the actual use needs of users.

[0004] Therefore, there is a contradiction between reliable positioning and stepless lifting in the existing lifting solutions, and the existing lifting solutions require large force rotation or bump pressing, which is inconvenient to operate and damages the appearance. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide a support structure and a vertical electric fan to solve the problem of the contradiction between reliable positioning and stepless lifting in the existing lifting solutions.

[0006] To achieve the above purpose, according to one aspect of the utility model, a support structure is provided. The support structure includes:

[0007] A first support member;

[0008] A second support member, the top of the first support member is located below the second support member, and the top of the first support member is detachably connected to the bottom of the second support member;

When the adjusting member is located at the locking position, the first engaging portion is connected to the second engaging portion to relatively fix the first support member and the second support member. When the adjusting member is located at the unlocking position, the first engaging portion and the second engaging portion are separated from each other to relatively move the first support member and the second support member, so as to adjust the height of the first support member.

[0011] Further, the first support member is elliptical, the second support member is circular, and the second support member is sleeved outside the first support member; and / or the first engaging portion and the second engaging portion are respectively an internal thread and an external thread that are in threaded engagement.

[0012] Further, the adjusting member is rotatably disposed on the second support member. A limiting protrusion is provided on the adjusting member, and a limiting groove is provided on the second support member. The limiting protrusion is rotatably limited in the limiting groove. Wherein, the first engaging portion is provided on the limiting protrusion, and the second engaging portion is provided on the first support member.

[0013] Further, the adjusting member is sleeved on the first support member. The first engaging portion is an internal thread provided on the limiting protrusion facing the first support member, and the second engaging portion is an external thread provided on the first support member.

[0014] Further, there are a plurality of limiting protrusions and limiting grooves, and the plurality of limiting protrusions and limiting grooves are provided 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 cooperating with the first clamping protrusion is provided on the limiting protrusion. When the limiting protrusion moves to a position where the first engaging portion and the second engaging portion are connected, the first clamping protrusion is clamped into the first clamping groove to limit the adjusting member at the locking position; and / or

[0016] A second clamping protrusion is provided on the inner wall of the limiting groove, and a second clamping groove cooperating with the second clamping protrusion is provided on the limiting protrusion. When the limiting protrusion moves to a position where the first engaging portion and the second engaging portion are disengaged, the second clamping protrusion is clamped into the second clamping groove to limit the adjusting member at the unlocking position.

[0017] Further, the adjusting member includes a main ring body, and the limiting protrusion is provided on the main ring body and protrudes from one end of the main ring body; an annular limiting portion is provided on the inner wall of the main ring body.

[0018] Wherein, the support structure further includes:

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

[0020] A fastening member, which passes through the annular cover plate and is connected to the second support member to fasten the annular cover plate.

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

[0022] A first ring body portion, the diameter of the first ring body portion being smaller than the inner diameter of the inner wall of the second support member, and a limiting protrusion being provided on the first ring body portion; the first ring body portion is located inside the second support member;

[0023] A second ring body portion, the second ring body portion being located on a side of the first ring body portion away from the limiting protrusion, the diameter of the second ring body portion being greater than or equal to the outer diameter of the outer wall of the second support member, and the second ring body portion being located outside the second support member.

[0024] Further, the first support member is a corrugated pipe, the corrugated pipe has an external thread, the second engaging portion is an external thread provided on the first support member, and the first engaging portion is an internal thread provided on the adjusting member and facing the first support member and capable of meshing with the external thread.

[0025] According to another aspect of the present utility model, there is provided an upright electric fan, including a support structure and a fan head mounted thereon, and the support structure is the support structure described above.

[0026] Applying the technical solution of the present utility model, during use, when it is necessary to adjust the height of the bottom of the second support member relative to the ground, the adjusting member can be manually rotated so that the adjusting member moves to the unlocking position, thereby separating the first engaging portion from the second engaging portion, releasing the locking between the first support member and the second support member. Therefore, the second support member can be moved along the vertical direction to achieve changing 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 member can be adjusted in the reverse direction so that the adjusting member gradually moves from the unlocking position to the locking position, so that the first engaging portion and the second engaging portion are connected to each other, thereby making the first support member and the second support member relatively fixed to avoid the first support member or the second support member moving in the vertical direction during normal use.

[0027] Compared with the prior art, through the technical solution of the present application, when adjusting the height, there is no need to manually press the bumps, nor to adjust by manually rotating the locking bolt. Only by rotating the position of the adjusting member can the adjusting member be switched between the unlocking position and the locking position. During the process of switching the position of the adjusting member, the first engaging portion and the second engaging portion are switched between the engaged state and the separated state. In this way, the height of the second support member relative to the ground can be adjusted, and moreover, the height of the second support member relative to the ground can be adjusted according to the user's needs. In the prior art, it can only be adjusted to a fixed position. Moreover, when adjusting in the prior art, it is also necessary to press the small bumps, which will cause strong pain to the user during use and affect the user experience. And in this way, the internal spring catch may fail. When the user is adjusting and the internal spring catch cannot be used normally, it may cause the circulation fan to fail to perform its normal functions, or even the circulation fan may be damaged. Even more seriously, it may cause certain harm to the user's body. In addition, in the prior art, it is also necessary to rotate the bolt, and the circulation fan is fixed at the preset height by the tightening force of the bolt. During the use process, the user needs to use a lot of force to rotate the bolt. If the bolt is not tightened, the height of the circulation fan cannot be fixed, which will also affect the user experience. At the same time, during the long-term use process, the bolt may be lost or rusted. All of the above will affect the user experience. On the contrary, in the present application, only a simple adjusting member can be used to adjust the height of the second support member relative to the ground, and thus the height of the entire circulation fan can be adjusted. Compared with the adjustment method in the prior art, it is more convenient and easier. And in the case of long-term use, the adjusting member in the present application will not have the above-mentioned problems. When the user is operating, only by rotating the adjusting member around the axis of the first support member or the second support member is needed, without 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 the preset fixed position, while the present application will not be affected by this and can be adjusted at multiple positions, greatly meeting the user's needs compared with the prior art. And in terms of the overall appearance, it is more beautiful than the prior art. Brief Description of the Drawings

[0043] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will describe the present utility model in detail with reference to the drawings and in combination with the embodiments.

[0044] The circulation fan is an important component of the household electric fan. The heights of many current circulation fans are adjustable, generally by the way of bolt-locking telescopic rods. The bolts need to be exposed on the appearance, with a protruding shape, which affects the consistency of the overall appearance of the circulation fan. And when adjusting the height, a large force is required to rotate to achieve positioning. If the bolts are not tightened, there is a risk of positioning failure. There are also some circulation fans that need to be positioned by internal snap buttons when adjusting the height, and small bumps need to be pressed to release the limiting relationship between the sleeve and the internal corrugated pipe. Because the contact area between the small bumps and the hand is small, it will cause pain in the hand when pressing, with a poor experience. And this adjustment method can only adjust the fan to the pre-set position and cannot be adjusted according to the actual usage needs of the user.

[0045] Therefore, there is a contradiction between reliable positioning and stepless lifting in the existing lifting solutions, and the existing lifting solutions require large-force rotation or bump pressing, which is inconvenient to operate and damages the appearance.

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

[0047] First of all, this application provides a support structure, and the support structure includes: a first support member 1;

[0048] A second support member 2, 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 member 15, a first mating portion 3 is provided on the adjusting member 15. The adjusting member 15 can be arranged on the first support member 1 or the second support member 2, and a second mating portion 4 is arranged on the other of the first support member 1 and the second support member 2, and the first mating portion 3 and the second mating portion 4 are arranged in a mating manner;

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

[0051] Specifically, as Figures 1 to 9 shown, the present application provides a support structure. The support structure includes a first support member 1, and a second support member 2 is disposed 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. The support structure further includes an adjusting member 15. The adjusting member 15 can be disposed on either the first support member 1 or the second support member 2. A first engaging portion 3 is disposed on the adjusting member 15, and a second engaging portion 4 is disposed on the other of the first support member 1 and the second support member 2. The first engaging portion 3 can be used in cooperation with the second engaging portion 4. Among them, the adjusting member 15 is disposed in an adjustable manner and can move to a locking position or an unlocking position. When the adjusting member 15 moves to the locking position, the first engaging portion 3 is connected to the second engaging portion 4, so that the positions of the first support member 1 and the second support member 2 are relatively fixed. When the adjusting member 15 moves to the unlocking position, the first engaging portion 3 and the second engaging portion 4 are separated from each other. Therefore, the first support member 1 and the second support member 2 can move relative to each other in the vertical direction, thereby realizing the adjustment of the height of the first support member 1.

[0052] During use, when it is necessary to adjust the height of the second support member 2, the adjusting member 15 can be moved to the unlocking position, so that the first engaging portion 3 and the second engaging portion 4 are separated from each other, and the locking between the first support member 1 and the second support member 2 is released. Therefore, the second support member 2 can be moved along the vertical direction. When the second support member 2 is moved to a preset position, the adjusting member 15 can be moved to the locking position again, and the first engaging portion 3 and the second engaging 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, by the technical solution of the present application, when adjusting the height, there is no need to press the bump, nor to adjust by means of a locking bolt. Only by adjusting the position of the adjusting member 15 can the height of the second support member 2 be adjusted, and moreover, the height of the second support member 2 can be adjusted according to the needs of the user. In the prior art, it can only be adjusted to a fixed position. The technical solution provided by the present application does not have a 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 oval, the second support member 2 is circular, and the second support member 2 is sleeved outside the first support member 1; and / or the first mating portion 3 and the second mating portion 4 are respectively an internal thread and an external thread in threaded fit.

[0055] Specifically, as Figure 3 、 Figure 4 shown, in the embodiment of the present application, the first support member 1 is oval, the second support member 2 is circular, and the second support member 2 is sleeved outside the first support member 1. The first mating portion 3 is an internal thread, and the second mating portion 4 is an external thread. When in use, when the adjusting member 15 is in the locked position, the internal thread and the external thread mesh 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 limit the adjusting member 15, the adjusting member 15 is rotatably arranged on the second support member 2. A limiting protrusion 5 is arranged on the adjusting member 15, and a limiting groove 6 is arranged on the second support member 2. The limiting protrusion 5 is rotatably limited in the limiting groove 6; wherein, the first mating portion 3 is arranged on the limiting protrusion 5, and the second mating portion 4 is arranged on the first support member 1.

[0057] Specifically, as Figure 2 and Figure 4 shown, the adjusting member 15 is rotatably connected to the second support member 2. A limiting protrusion 5 is arranged on the adjusting member 15, and a limiting groove 6 is arranged 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. 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 member 15 is in the locked position. When the limiting protrusion 5 slides to the second limiting end, the adjusting member 15 is in the unlocked position. By rotating the adjusting member 15, it is possible to drive the limiting protrusion 5 to switch between the first limiting end and the second limiting end, thereby realizing the fixing or unlocking of the positional relationship between the first support member 1 and the second support member 2.

[0058] With the structure of the present application, only by rotating the adjusting member 15 to switch the limiting protrusion 5 between the first limiting end and the second limiting end, the adjusting member 15 can be switched between the locking position and the unlocking position, so as to fix or unlock the relative position relationship between the first support member 1 and the second support member 2, and adjust the height of the second support member 2.

[0059] Further, the adjusting member 15 is sleeved on the first support member 1. The first engaging portion 3 is an internal thread provided on the limiting protrusion 5 facing the first support member 1, and the second engaging portion 4 is an external thread provided on the first support member 1.

[0060] Specifically, the adjusting member 15 is partially sleeved on the first support member 1. Among them, the first engaging portion 3 is provided on the limiting protrusion 5 and faces the internal thread on the first support member 1. The second engaging portion 4 is provided on the first support member 1 and faces the external thread on the second support member 2. The internal thread and the external thread can be engaged with each other or separated relatively.

[0061] Embodiment 1

[0062] Specifically, as Figure 4 , Figure 10 , Figure 1 shown, both the limiting protrusion 5 and the limiting groove 6 can be provided in multiple numbers, and the multiple limiting protrusions 5 and the limiting grooves 6 correspond to each other one by one. In this embodiment, both the limiting protrusion 5 and the limiting groove 6 are provided in two numbers. Among them, the limiting groove 6 presents an arc structure. As Figure 11 shown, the limiting groove 6 has an inner arc side and an outer arc side, and the radian bending angle of the inner arc side is the same as the radian of the first support member 1, and the bending angle of the outer arc side is the same as the inner side wall of the second support member 2, that is, the inner arc side is attached to the outer wall of the first support member 1, and the outer arc side is attached to 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 (the inner side wall of the limiting protrusion 5) of the limiting protrusion 5 is attached to the outer wall of the first support member 1, and the second side wall (the outer side wall of the limiting protrusion 5) of the limiting protrusion 5 is attached to the inner side wall of the second support member 2. When the limiting protrusion 5 is in the unlocking 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 attached to the inner side wall of the second support member 2. That is, during the rotation of the adjusting member 15, the outer side wall of the limiting protrusion 5 is always attached to 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] Embodiment 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, Figure 10 and Figure 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] Further, the adjusting member 15 includes a main ring body 11, and the limiting protrusion 5 is disposed on the main ring body 11 and protrudes from one end of the main ring body 11; an annular limiting portion 12 is disposed on the inner wall of the main ring body 11;

[0073] A fastening member 14, which 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, as Figure 2 shown, the adjusting member 15 includes a main ring body 11. Among them, the limiting protrusion 5 is disposed on the main ring body 11 and protrudes from one end of the main ring body 11. An annular limiting portion 12 is disposed on the inner wall of the main ring body 11. The inner diameter of the annular limiting portion 12 is smaller than the inner diameter of the main ring body 11. The support structure further includes an annular cover plate 13 disposed in the main ring body 11 and abutting against the annular limiting portion 12. It also includes a fastening member 14. In this embodiment, the fastening member 14 is a fastening screw. A threaded hole is provided on the annular cover plate 13. The fastening member 14 can pass through the annular cover plate 13 through the threaded hole and be connected to the second support member 2 to realize the fastening of the annular cover plate 13. Since the annular cover plate 13 is disposed 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 member 14, axial positioning can be provided for the adjusting member 15, avoiding the adjusting member 15 from disengaging from the second support member 2 during the rotation process.

[0075] Further, the second support member 2 is tubular. 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 inner diameter of the inner wall of the second support member 2, and the limiting protrusion 5 is disposed on the first rotating portion; the first ring body portion 16 is located inside the second support member 2;

Wherein, the limiting protrusion 5 is arranged on the first ring body portion 16, the first ring body portion 16 being located inside the second support member 2. It further includes a second ring body portion 17, the second ring body portion 17 being 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 being greater than or equal to the outer diameter of the second support member 2, the second ring body portion 17 being located outside the second support member 2.

[0078] Further, the first support member 1 is a corrugated pipe, the corrugated pipe having an external thread, the second mating portion 4 being the external thread provided on the first support member 1, and the first mating portion 3 being the internal thread provided on the adjusting member 15 and facing the first support member 1 and capable of meshing with the external thread.
