Description

Supporting and fixing structure and fan Technical Field

[0001] The utility model relates to the technical field of fans, and more particularly to a supporting and fixing structure and a fan. Background Art

[0002] Portable fans are popular among consumers due to their compact size and convenience. However, the base used to support existing portable fans is usually only suitable for balanced placement on a stable platform. It is prone to shaking or tipping over due to collisions or vibrations, resulting in poor stability during placement and limited use. Although some fans use adhesives on the base to stabilize the fan, the adhesive has a limited adhesive property and is prone to aging after long-term use, resulting in unstable adhesion. As the adhesive stability gradually deteriorates, the fan is easily affected by the weight of the fan head, which can cause it to shake or tip over, and its stability is also insufficient. Moreover, the adhesive is easy to leave and difficult to clean, resulting in significant limitations in the use of such fans. The fan's placement stability needs to be improved. Technical issues

[0082] The support base 10 is connected to a mounting base 12 located above the support base 10 via three first positioning studs 1001 .

[0083] Mounting Block 12

[0084] The mounting base 12 is cylindrical in shape. The mounting base 12 has a bottom wall 121, a side wall extending vertically upward from the periphery of the bottom wall 121 and arranged around the bottom wall 121, and a second top wall 122 bent outward from the top of the side wall and perpendicular to the side wall to form a positioning recess 1201. The bottom wall 121 and the side wall located above it form a third groove. The side wall on the bottom wall 121 also extends downward (i.e., extends in a direction away from the second top wall 122) beyond the bottom wall 121 to form a fourth groove. The bottom wall 121 is circular, and the side wall and the second top wall 122 are both annular. A first through hole 1211 is provided at the center of the bottom wall 121. The bottom wall 121 also has three first screw holes 1212 distributed in sequence and at equal intervals along the circumference of the side wall. The three first screw holes 1212 all pass through the bottom wall 121 of the mounting base 12. Three blocks 1213 are provided at an upper position of the side wall, i.e., at the top edge of the third groove, and are distributed equidistantly along the circumference of the side wall. The top surfaces of the three blocks 1213 are all located on the same horizontal plane as the second top wall 122, and a second gap is defined between the bottom surfaces of the three blocks 1213 and the bottom wall 121. The bottom surfaces of the three blocks 1213 are also each provided with a bayonet 12130, which is shaped like an arch bridge. The bottom wall 121 is also provided with a second through hole 1214 at a position between two of the first screw holes 1212. The first through hole 1211, the second through hole 1214, and the first screw hole 1212 all extend through the bottom wall 121.

[0085] A first protrusion 1215 is disposed within the fourth recess at a position corresponding to the second through-hole 1214. The interior of the first protrusion 1215 is hollow and communicates with the second through-hole 1214. Referring also to Figure 7 , the sidewall of the first protrusion 1215 (the outward-facing sidewall) facing away from the first through-hole 1211 is arcuately convex. This sidewall defines a retaining hole 12151 that communicates with the interior of the first protrusion 1215. This retaining hole 12151 is in an inverted U-shape. A retaining post 12152 is disposed within the first protrusion 1215. One end of the retaining post 12152 is fixedly mounted on the inner sidewall of the first protrusion 1215, while the other end faces the retaining hole 12151. A ball 12153 is movably positioned within the retaining hole 12151. The portion of the ball 12153 that protrudes from the retaining hole 12151 does not exceed one-third of the diameter of the ball 12153. A retaining block 12154 is also provided on the inner bottom surface of the retaining hole 12151, at a position corresponding to the ball 12153. The side wall of the retaining block 12154 that contacts the ball 12153 has a second recess 121541, which has a slope that is higher on the outside and lower on the inside. Second retaining blocks 12155 are correspondingly provided on the two side walls of the first retaining block 1215 adjacent to the side wall containing the retaining hole 12151.

[0088] The size of the support plate 201 matches the size of the third opening 1030. Two second screw holes 2011 are defined on the upper sidewall of the support plate 201. A first mounting hole 2012 is also defined on the upper sidewall of the support plate 201, centrally located between the left and right second screw holes 2011. The first mounting hole 2012 is rectangular in shape.

[0089] The top and bottom wall surfaces of the clamping plate 202 are both provided with a plurality of diamond-shaped notches.

[0090] Lifting assembly 30

[0091] Referring to Figures 3 and 4 , the lifting assembly 30 includes a screw 31, a slider 32 mounted on the screw 31, a first gear 33 mounted on the screw 31 and located above the slider 32, and a second gear 34 positioned to one side of and meshing with the first gear 33. The slider 32 is mounted on the screw 31 and is connected to the screw 31 by a threaded rotational engagement. The first gear 33 is fixedly mounted on the top of the screw 31 (i.e., near the top end of the screw 31).

[0092] One sidewall of the slider 32 is convexly curved, its dimensions matching the second opening 10111 and the baffle 10112. A first connecting plate 312 is provided on the sidewall of the slider 32 opposite the curved sidewall. A second rectangular mounting hole 3120 is defined in the center of the first connecting plate 312. Limiting rods 3120 are provided on the left and right sides of the second mounting hole 3120, with a certain distance between them. A rectangular mounting block 3210 is also provided in the center of the sidewall of the slider 32 opposite the curved sidewall. The dimensions of this mounting block 3210 match those of the first mounting hole 2012. The first connecting plate 312 is provided with a second protrusion 321 on the left and right sides of the slider 32. Third screw holes 3121 are provided in the two second protrusions 321 and at positions on the first connecting plate 312 corresponding to the two second protrusions 321. A first guide post 341 is fixed to the inner ring of the second gear 34.

[0093] Adjustment device 40

[0094] Referring to Figures 3 and 4 , the adjustment device 40 is annular in shape. A plurality of first gear teeth 401 are disposed in the middle portion of the inner circumference of the adjustment device 40, extending around the inner circumference. The spacing between any two adjacent first gear teeth 401 is uniform, and the first gear teeth 401 are configured to mesh with the second gear 34. A plurality of second gear teeth 402 are disposed on the outer circumference of the adjustment device 40, extending around the outer circumference. The spacing between any two adjacent second gear teeth 402 is also uniform.

[0095] During installation, first insert the top of the support plate 201 through the third opening 1030, ensuring that the majority of the support plate 201 is within the cavity and the left and right sidewalls of the support plate 201 are close to the cavity walls. The top of the support plate 201 is correspondingly located within the first opening 1011. The third opening 1030 prevents the support plate 201 from shifting during the lifting process. Insert the mounting block 3210 on the slider 32 into the second mounting hole 3120 of the first connecting plate 312, and secure the mounting block 3210 therein by using the space between the two limiting rods 31200. The screw rod 31 with the slider 32 and the first connecting plate 312 is then inserted into the cavity from the area where the first opening 1011 and the second opening 10111 communicate. The slider 32 is then placed in the second opening 10111 and the first connecting plate 312 is affixed to the support plate 201. During this affixation, the mounting block 3210 is inserted into the first mounting hole 2012 and secured therein. The mounting block 3210 partially passes through the first mounting hole 2012 and protrudes from the outside of the first mounting hole 2012. At this point, the two third screw holes 3121 and the two second screw holes 2011 are also in a one-to-one correspondence. The first connecting plate 312 and the support plate 201 are then connected by sequentially inserting fastening screws (not shown in the drawings) into the two third screw holes 3121 and the two second screw holes 2011.

[0096] Then, the mounting base 12 is positioned above the support base 10, and the top portion of the screw rod 31 with the first gear 33 is movably inserted into the first through hole 1211. The two ends of the first guide column 341 of the second gear 34 are respectively inserted into the second through hole 1214 and the first blind hole 10021 to limit the second gear 34. At the same time, the first gear 33 and the second gear 34 are meshed with each other. At this time, the three first screw holes 1212 and the three first positioning studs 1001 are in a one-to-one correspondence. Then, the mounting base 12 and the support base 10 are connected by sequentially inserting fastening screws (not shown in the drawings) into the three first screw holes 1212 and the three first positioning studs 1001. Please refer to Figure 5 for the layout of the clamping member 20 and the lifting assembly 30 in the support base 10.

[0097] Please refer to Figures 2, 6 and 7. After the mounting base 12 and the support base 10 are connected, the fourth groove is opposite to the first groove, and a first gap is formed between the top of the support base 10 and the bottom of the mounting base 12 for the multiple first gear teeth 401 on the adjusting device 40 to be inserted to engage with the second gear 34; a rotating space for the adjusting device 40 to rotate therein is formed between the top outer edge of the support base 10 and the top outer edge of the mounting base 12 (that is, between the second groove and the side walls on the second top wall 122 and the bottom wall 121).

[0098] In this embodiment, in order to increase the stability of the connection between the slider 32 and the first connecting plate 312 , the slider 32 and the first connecting plate 312 may be configured as an integrally formed connection structure. Example 2

The motor 1312 has a rotating shaft 13120, with two third recesses defined on the outer sidewall of the rotating shaft 13120, the recesses facing each other and extending to the bottom wall of the rotating shaft 13120. The rotating shaft 13120, with its two third recesses, is T-shaped.

[0102] Referring to Figures 12 to 15 , the bottom of the rotating shaft 13120 is inserted into a circular connector 1313. This connector 1313 is placed within the accommodating chamber, covering the third through hole 13100 and located below the motor 1312. A central insertion hole 13130 ​​is defined within the connector 1313 for inserting the rotating shaft 13120. A fifth screw hole 13131 is defined on the left and right sides of the insertion hole 13130. When the connector 1313 is placed within the accommodating chamber, the insertion hole 13130 ​​and the two fifth screw holes 13131 are positioned relative to each other within the opening of the third through hole 13100. A third protrusion 13132 is also provided on the outer sidewall of the connector 1313. The two opposing sidewalls of the third protrusion 13132, adjacent to the outer sidewall of the connector 1313, are each configured with a recessed wall surface. The bottom wall of the connecting member 1313 is further provided with a circular second protrusion 13133 surrounding the insertion hole 13130 ​​and the two fifth screw holes 13131 , and the cross-section of the second protrusion 13133 is semicircular.

[0103] Referring to Figures 16 and 17 , the bottom wall of the tee 1310 is formed with a fifth circular groove 1314. A cylindrical fourth protrusion 13140 is positioned at the center of the inner top surface of the fifth groove 1314. The fourth protrusion 13140 is formed with a fourth through-hole 13141 that intersects the third through-hole 13100. The outer sidewall of the fourth protrusion 13140 is provided with a plurality of equally spaced vertical third protrusions 131400. The lower portions of the sidewalls facing away from each other are each provided with an inclined surface. A bearing 13142 is also positioned within the fifth groove 1314. The inner ring of the bearing 13142 is fixedly mounted on the outer sidewall of the fourth protrusion 13140.

[0104] The connecting member 1313 is connected to the base 130 through two fifth screw holes 13131 . The base 130 includes a mounting plate 1315 and a bottom plate 1316 .

[0105] Mounting plate 1315 is circular in shape. A sixth groove 13150 is defined on the top wall of mounting plate 1315. Two spaced-apart third positioning studs 13151 are located at the center of the inner bottom surface of sixth groove 13150. Three sixth screw holes 13152 are also defined on the top wall of mounting plate 1315, equidistantly around the edge of sixth groove 13150. A raised ring 13153 is fixedly mounted on the outer sidewall of mounting plate 1315. This raised ring 13153 is provided with a plurality of fourth protrusions 131530 arranged at equal intervals vertically along the outer sidewall of raised ring 13153. A seventh groove 13154 is provided on the bottom wall of the mounting plate 1315, and second guide pillars 131540 are respectively provided on the top surface of the seventh groove 13154 at positions corresponding to the three sixth screw holes 13152, and seventh screw holes 131541 that penetrate the sixth screw holes 13152 are respectively provided in the three second guide pillars 131540.

[0106] Mounting plate 1315 is also connected to base plate 1316 via three sixth screw holes 13152, second guide posts 131540, and seventh screw holes 131541. Base plate 1316 is located at the bottom of mounting plate 1315. Base plate 1316 is circular in shape. An eighth groove 13160 is defined in the top wall of base plate 1316. Three third guide posts 13161 are located within the inner bottom surface of eighth groove 13160. Each of the three third guide posts 13161 defines a second blind hole. The three second blind holes accommodate the insertion of three second guide posts 131540, and the dimensions of the second blind holes match those of the second guide posts 131540. The inner bottom surfaces of the three second blind holes each define an eighth screw hole 131610 that penetrates the bottom wall of base plate 1316. The base plate 1316 also has a fan-shaped notch 13162 located between any two adjacent third guide posts 13161. A positioning protrusion 13163 is provided on the bottom wall of the base plate 1316 at a position corresponding to each of the three notches 13162. A latching slot 13164 communicating with the notch 13162 is provided on a side wall facing away from each of the three positioning protrusions 13163. The cross-section of each of the three latching slots 13164 is L-shaped. The dimensions of the latching slot 13164 match those of the latching block 1213. Each of the three latching slots 13164 has a second protrusion 131640 on its inner bottom surface, shaped like an arch bridge. When the mounting base 12 is assembled with the base 130, the three positioning protrusions 13163 can be received within the positioning recess 1201 to engage with the corresponding latching slot 13164. The second protrusion 131640 can be adapted to be snapped into the bayonet 12130 . Through the snap-fitting cooperation between the bayonet 12130 and the second protrusion 131640 , the assembly of the mounting seat 12 and the base 130 can be further stabilized.

[0107] During installation, base plate 1316 is placed below mounting plate 1315, with eighth groove 13160 facing seventh groove 13154. Simultaneously, three second guide posts 131540 are inserted into the second blind holes of third guide posts 13161, one-to-one, with sixth screw hole 13152 and seventh screw hole 131541 aligned with eighth screw hole 131610. Fastening screws (not shown) are then sequentially inserted into sixth screw hole 13152, seventh screw hole 131541, and eighth screw hole 131610 to securely connect base plate 1316 to mounting plate 1315. Connecting member 1313 is then placed within the accommodating cavity, and mounting plate 1315 is placed at the bottom of tee 1310, with sixth groove 13150 facing fifth groove 1314. Bearing 13142 is positioned within sixth groove 13150, with the inner circumferential sidewall of sixth groove 13150 tightly fitted with the outer ring of bearing 13142. Then, the two third positioning studs 13151 on the mounting plate 1315 are passed through the fourth through hole 13141 and the third through hole 13100 at the bottom of the tee 1310, and then correspond one-to-one with the two fifth screw holes 13131 on the connecting piece 1313. Then, fastening screws (not shown in the drawings) are inserted into the fifth screw holes 13131 and the screw holes in the third positioning studs 13151 in sequence to fix the mounting plate 1315 to the connecting piece 1313.

[0108] During connection, the third protrusion 13132 on the connecting member 1313 must be positioned between the two second positioning studs 1311. Then, the motor 1312 is placed in the accommodating cavity, and the rotating shaft 13120 on the motor 1312 is inserted into the insertion hole 13130 ​​of the connecting member 1313. At the same time, the fourth screw holes 13122 on the second connecting plates 13121 on both sides of the motor 1312 are aligned with the screw holes in the two second positioning studs 1311, respectively. Fastening screws (not shown) are then used to thread the motor 1312 into the second positioning studs 1311 through the fourth screw holes 13122 on the second connecting plates 13121.

[0109] Once installed, the motor 1312 drives the tee 1310 and base 130 to rotate relative to each other. Furthermore, once the base 130 and mounting base 12 are securely connected via the latching slots 13164 and the latching blocks 1213, and the base 130 is positioned on the mounting base 12, the tee 1310 can drive the connecting rod 1311 thereon to rotate left and right. During rotation, the third protrusion 13132 on the connecting member 1313 and the two second positioning studs 1311 achieve rotational restraint, allowing the tee 1310 to rotate within a set range and within a certain angle.

[0110] It should be noted that the structure of the bearing 13142 in the drawings of this embodiment is only an example. In actual application, any existing bearing that can realize the rotation of the inner and outer rings can be used, and the drawings do not constitute a specific limitation. Example 3

[0111] Referring to Figures 19 and 21 , two connecting rods 1311 connect the fan head 50. This allows the fan head 50 to swing as the mounting bracket 13 rotates. The fan head 50 and the two connecting rods 1311 are pivotally connected. The structure of the pivotal connection between the fan head 50 and the two connecting rods 1311 can refer to existing structures and is not specifically limited here. In other embodiments, the fan head 50 and the two connecting rods 1311 can also be fixedly connected. Fixed connection structures are relatively common and can be referred to existing structures and are not specifically limited here. Example 4

[0112] Please refer to Figures 22 to 24. In this embodiment, a locking mechanism is provided between the mounting seat 12 and the base 130; the locking mechanism includes a pin rod 60, which is slidingly mounted on the base 130 in a limited position; a limiting protrusion 61 is provided on the pin rod 60. After the mounting seat 12 and the base 130 are rotated and clamped into place through the clamping block 1213 and the clamping groove 13164, the pin rod 60 is configured to drive the limiting protrusion 61 to move, and the limiting protrusion 61 moves to one side of the direction in which the clamping block 1213 is screwed out and abuts against the clamping block 1213. The moving direction at this time is also the locking direction, which can limit the clamping block 1213 from being screwed out, thereby locking the mounting seat 12 and the base 130. As shown in Figure 24, the assembly stability between the mounting seat 12 and the base 130 is further improved, and the use effect is better. On the contrary, if the operating pin 60 moves in the opposite direction, the moving direction at this time is also the unlocking direction, which can make the limiting protrusion 61 no longer abut against the block 1213, as shown in Figure 26, making it easier for the block 1213 to rotate out of the slot 13164, thereby separating the mounting seat 12 and the base 130.

[0113] In this embodiment, the mounting seat 12 and the base 130 are both disc-shaped. As shown in FIG25 , a through slot 1301 is provided at the center of one side of the base 130 facing the mounting seat 12. The two ends of the through slot 1301 extend through the outer peripheral sidewall of the base 130. The pin 60 is slidably mounted within the through slot 1301, and the pin 60 does not protrude from the through slot 1301. Specifically, a first stopper 1302 and a second stopper 1303 are provided on the side of the base 130 facing the mounting seat 12, opposite to the through slot 1301. The first stopper 1302 and the second stopper 1303 are spaced apart along the length of the through slot 1301. The two ends of the first stopper 1302 and the second stopper 1303 are located at the two side edges of the through slot 1301, and the surfaces of the first stopper 1302 and the second stopper 1303 facing the through slot 1301 are both smooth. When the pin rod 60 is slidably disposed in the through slot 1301 , the limiting protrusion 61 is located on the side of the first stopper 1302 away from the second stopper 1303 to limit the movement of the pin rod 60 .

[0114] Furthermore, the pin 60 is provided with a first protrusion 601 that engages with the second stop 1303. The limiting protrusion 61 and the first protrusion 601 are located on the same side of the pin 60, with a gap between them. The first protrusion 601 is close to the second stop 1303 and has a hemispherical shape. When the limiting protrusion 61 abuts the locking block 1213, the first protrusion 601 is locked onto the second stop 1303, further limiting the movement of the pin 60.

[0115] In this embodiment, both ends of the pin 60 are located outside the through slot 1301. Specifically, a shift block 62 is provided on the outer end of the pin 60, near the stopper 61. Pulling or pushing the shift block 62 allows the pin 60 to move back and forth relative to the base 130 and the mounting base 12, thereby achieving locking or unlocking operations. A third stop 63 is provided on the outer end of the pin 60, away from the stopper 61, to prevent the pin 60 from moving too far.

[0116] It should be noted that the "upward" and "downward" perspectives of the mounting seat 12 and the base 130 shown in the accompanying drawings are only for the purpose of clearly illustrating the relevant structural layout, and do not limit the assembly, placement or use orientation of the mounting seat 12 and the base 130. Example 5

[0117] Please refer to FIG. 27 . An embodiment of the present invention further provides a fan, which includes the supporting and fixing structure with a locking function provided in the fourth embodiment.

[0118] It should be understood that ordinary technical workers in this field can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to this utility model.
