Description

Technical Field

[0001] This utility model relates to the field of portable fan technology, specifically to a fan with a portable clamping mechanism. Background Technology

[0002] In summer, people often use electric fans at home. There are many types of electric fans, such as ceiling fans, table fans, and wall fans. To meet the needs of different occasions, different types of electric fans have also emerged, such as electric fans with clips, which can be clipped to bedside tables, partitions, and other places.

[0003] In the prior art of desktop fans, for example, Chinese utility model patent with authorization announcement number CN214577828U discloses a multi-functional clip-on fan base. The multi-functional clip-on fan base includes an upper clamping plate, a lower clamping plate, and a torsion spring. The other end of the lower clamping plate and the upper clamping plate is a clamping end. The multi-functional clip-on fan base also includes a V-shaped frame with an opening at one end. The other end of the V-shaped frame has an arc structure, the diameter of which is smaller than the spacing of the opening. The opening of the V-shaped frame is hinged to the bottom of the lower clamping plate, allowing the V-shaped frame to rotate relative to the lower clamping plate and form a first position and a second position. In the first position, the V-shaped frame is in contact with the bottom of the lower clamping plate, and the V-shaped frame is adjacent to the clamping end side. In the second position, the V-shaped frame forms an angle with the lower clamping plate, and the V-shaped frame is adjacent to the torsion spring side. However, when this type of clamp is in the clamping state, the two clamping ends are set at an acute angle. When the upper clamping end is parallel to the desktop and in close contact with the desktop, the lower clamping end is at an angle to the desktop. In other words, the lower clamping end is in line contact with the desktop, resulting in poor fan stability, poor clamping effect, and easy scratches on the desktop surface. Utility Model Content

[0035] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0036] like Figure 1-7 As shown, the following embodiments disclose a fan with a portable clamping mechanism.

[0037] Example 1

[0038] A fan with a portable clamping mechanism includes a fan body 100 and a base 200; a clamping plate 300 is hinged to the base 200 via a first pivot 1, and the clamping plate 300 and the base 200 are combined to form a clamping structure.

[0039] The clamping plate 300 includes an operating plate 320 and an adjusting plate 310 spliced ​​together. The operating end b and the clamping end a are located on the operating plate 320 and the adjusting plate 310 respectively, and are arranged opposite to each other.

[0040] The operation panel 320 is used to enable an open / closed state between the clamping end a and the base 200;

[0041] The adjustment plate 310 is hinged to the end of the operation plate 320 via the second rotating shaft 2, and can rotate relative to the operation plate 320 so that the clamping end a has a clamping end surface 311 parallel to the lower end surface of the base 200.

[0042] The above is the basic scheme of this embodiment.

[0043] Specific reference Figure 1 and Figure 2 As shown, the fan body 100 is a conventional fan head, which has a fan cover, an impeller and a motor. The fan body 100 is hinged to the base 200 and can rotate relative to the base 200, so as to adjust the airflow direction according to the user's needs.

[0044] The clamping plate 300 is located at the bottom of the base 200 and is hinged to the middle part of the base 200, and can rotate relative to the base 200; the user controls the opening and closing state of the clamping end a by operating the operating end b.

[0045] The adjustment plate 310 is spliced ​​to the head of the operation plate 320. The tail of the operation plate 320 is the operation end b, and the head of the adjustment plate 310 is the clamping end a. When the user applies force to the operation end b, causing the operation end b to approach the base 200, the clamping plate 300 rotates around the first rotating shaft 1, causing the adjustment plate 310 at the head to rotate. The head of the adjustment plate 310 moves away from the base 200, thereby putting the clamping end a in an open state. At this time, the open clamping structure can be clamped to the edge of the table. After releasing the hand, the operation end b returns to its original position and rotates towards the side away from the base 200, causing the clamping end a to rotate towards the side of the base 200, thus clamping the table.

[0046] In this embodiment, the hinge structure between the operation plate 320 and the base 200 is consistent with the clamping structure in the prior art. A torsion spring for resetting is provided on the first rotating shaft 1. The specific structure will not be described in detail here.

[0047] In the existing technology, only an integrally formed clamping plate 300 structure is provided. When clamping the edge of a tabletop of different thicknesses, the clamping end face 311 on the clamping end a forms an angle with the bottom surface of the base 200. Under the premise that the lower end face of the base 200 is in close contact with the tabletop, the clamping end face 311 and the tabletop are not parallel, thus forming a line contact. The fan has poor stability and the clamping effect is not good. At the same time, it is also easy to scratch the surface of the tabletop.

[0048] In this embodiment, the clamping plate 300 is configured as a splicing structure, and the adjusting plate 310 for clamping is hinged to the operating plate 320. When clamping the table, the adjusting plate 310 can adjust its position according to the thickness of the table, so that the clamping end face 311 of the clamping end a is flush with the lower end face of the base 200, thereby forming a surface contact with the table, making the clamping stable and preventing scratches on the surface of the table.

[0049] Preferably, in this embodiment, the first rotating shaft 1 and the second rotating shaft 2 are arranged in parallel.

[0050] Specific reference Figure 3 As shown, when the operating plate 320 rotates around the first rotating shaft 1 under the action of external force, it drives the adjusting plate 310 to rotate together, and the rotation angle is the same; when the clamping structure is opened and clamped onto the table, the adjusting plate 310 contacts the end face of the table, thereby adjusting its own state according to the clamping angle and rotating around the second rotating shaft 2.

[0051] Preferably, in this embodiment, the clamping end face 311 of the adjusting plate 310 is provided with an anti-slip pad 3.

[0052] In addition, to ensure the anti-slip effect, an anti-slip pad 3 is also provided on the lower end surface of the base 200 corresponding to the clamping end surface 311.

[0053] In addition, in this embodiment, in order to make the air blowing direction of the fan adjustable, a column 400 is provided between the fan body 100 and the base 200, and the two ends of the column 400 are respectively hinged to the fan body 100 and the base 200.

[0054] In other words, the fan body 100 can rotate relative to the column 400, and the column 400 can also rotate relative to the base 200, thus allowing the fan's airflow direction to be adjusted arbitrarily as needed. See details below. Figure 6 As shown.

[0055] In this embodiment, the specific implementation of the hinge structure between the clamping plate 300 and the base 200 is as follows: a pivot seat 312 is provided on the clamping plate 300, and a hinge ear 210 is formed on the lower end surface of the base 200. The first pivot 1 passes through the pivot seat 312 and the hinge ear 210.

[0056] Specific reference Figure 5 As shown, there are two pivot seats 312 and two hinge ears 210, which are arranged symmetrically. The first pivot 1 can extend from one of the pivot seats 312 and pass through the two hinge ears 210 and the pivot seat 312 on the opposite side, thereby connecting the hinge ears 210 and the pivot seats 312.

[0057] To ensure the connection of the first rotating shaft 1, in this embodiment, the outer side of the rotating shaft seat 312 is provided with a mounting groove 312.1, and the opening side of the mounting groove 312.1 is covered by a mounting cover 4.

[0058] After the first rotating shaft 1 passes through the two rotating shaft seats 312 and the hinge ear 210, its two ends are located in the mounting groove 312.1, which covers the mounting cover 4. In this way, the first rotating shaft 1 cannot be dislodged from the mounting groove 312.1, thus ensuring the stable installation of the first rotating shaft 1.

[0059] Example 2

[0060] This embodiment is an improvement on embodiment 1, and its purpose is to provide an adjustment plate 310 with a different structure. The specific implementation method is as follows:

[0061] In this embodiment, the adjustment plate 310 further includes an extension 316, which extends from the splicing part of the adjustment plate 310 toward the base 200.

[0062] Specific reference Figure 3 As shown, a clamping space is formed between the base 200 and the front of the operation plate 320. The extension 316 extends from the splicing part of the adjustment plate 310 toward the clamping space, and extends toward the base 200 to avoid the operation plate 320.

[0063] In this embodiment, the adjusting plate 310 is provided with a first stop surface 314 and a second stop surface 315. A stop is formed between the first stop surface 314 and the operating plate 320, so that the adjusting plate 310 is in a first extreme position; a stop is formed between the second stop surface 315 and the operating plate 320, so that the adjusting plate 310 is in a second extreme position.

[0064] Preferably, the front end face of the operation plate 320 is set as a straight surface, and the first stop surface 314 of the adjustment plate 310 is used to form a splice with the front end face of the operation plate 320, thereby ensuring the integrity of the splice and the appearance consistency of the bottom of the clamping plate 300.

[0065] When the bottom surface of the adjusting plate 310 and the bottom surface of the operating plate 320 are spliced ​​together to form an integral part, the first stop surface 314 coincides with the front end surface of the operating plate 320, and the adjusting plate 310 cannot rotate relative to the operating plate 320. At this time, the adjusting plate 310 is in an extreme position relative to the operating plate 320.

[0066] During clamping, the adjusting plate 310 rotates relative to the operating plate 320. The second stop surface 315 of the adjusting plate 310 is the lower end surface of the extension 316. When the second stop surface 315 contacts the upper end surface of the operating plate 320, the adjusting plate 323 cannot continue to rotate relative to the operating plate 320. At this time, the adjusting plate 310 is in another extreme position. (Refer to...) Figure 8 As shown; that is, the rotation range of the adjustment plate 310 relative to the operation plate 320 is only between two extreme positions.

[0067] Example 3

[0068] This embodiment is an improvement on embodiment 2, the purpose of which is to enhance the function of the adjusting plate 310. The specific implementation method is as follows:

[0069] In this embodiment, the extension 316 is configured as an arc-shaped structure, and the end face facing the base 200 is configured as a concave surface, which forms a complete groove 310.1 with the end face of the adjustment plate 310.

[0070] Specific reference Figure 6 and Figure 7 As shown, when the clamping part is a pipe, the lower part of the pipe is embedded in the groove 310.1 for limitation, and the top part is abutted by the end face of the base 200, thereby achieving clamping of the pipe.

[0071] Example 4

[0072] This embodiment is an improvement based on embodiment 2 or embodiment 3. Its purpose is to increase the clamping force of the adjusting plate 310. The specific method is as follows:

[0073] The end of the extension 316 is provided with an auxiliary clamping surface 313 that is symmetrical to the clamping end surface 311.

[0074] Specific reference Figure 6 and Figure 7 As shown, in order to ensure the clamping effect, in this embodiment, an auxiliary clamping surface 313 is also provided at the end of the extension 316. The auxiliary clamping surface 313 is flush with the clamping end surface 311. When the clamping end surface 311 is in close contact with the end surface of the table, the auxiliary clamping surface 313 is also in close contact with the end surface of the table, thereby increasing the clamping force, improving the clamping effect, and making the fan more stable.

[0075] Preferably, an anti-slip pad 3 is also provided on the auxiliary clamping surface 313.

[0076] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
