Modes for Carrying Out the Invention

[0018] In the following description, only specific exemplary embodiments will be briefly described. As will be understood by those skilled in the art, the described embodiments can be modified in various ways without departing from the gist or scope of the present application. Therefore, the drawings and the description are to be regarded as illustrative rather than restrictive in nature.

[0019] Example 1 Figures 1 to 6 show structural diagrams of a clamping structure according to one embodiment of the present invention. As shown in Figures 1 to 6, the clamping structure is A bracket assembly 100 is provided on the seat-mounted fan 400, A rotating assembly 200 is provided on the bracket and rotates relative to the bracket assembly 100, The rotating assembly 200 may also include a clamping assembly 300 that is detachably provided on the rotating assembly 200, the clamping assembly 300 which clamps the seat-mounted fan 400 when in use.

[0020] In this embodiment, the clamping assembly 300 makes it easy to fix the waist-mounted fan 400 to suit various usage scenarios. After the waist-mounted fan 400 is fixed by the clamping assembly 300, the rotating assembly 200 is provided to rotate the clamping assembly 300 relative to the bracket assembly 100, further adjusting the angle of the waist-mounted fan 400, thereby improving the adjustability of the waist-mounted fan 400 and enabling airflow from various angles.

[0021] Furthermore, since the clamping assembly 300 is detachably attached to the rotating assembly 200, the clamping assembly 300 can be removed as needed, and the neck strap can be attached to the waist-mounted fan 400 for use.

[0022] Specifically, the clamping assembly 300 allows the waist-mounted fan 400 to be attached to clothing such as a belt or collar, and it can also be clamped to a bed head or upright rod (the usage scenarios here are not limited to the positions described above; it can be used in any situation where it can be clamped by the clamping assembly 300).

[0023] As shown in Figures 2 to 4, in one embodiment, The rotary assembly 200 is A first rotating block 210 having an engagement hole 211, A second rotating block 220 having a mounting groove 221 and an engagement groove 222, The first engaging block 230 provided on the second rotating block 220 includes a first engaging block 230 that penetrates the bracket assembly 100 and engages with an engaging hole 211 in order to provide the first rotating block 210 and the second rotating block 220 to the bracket assembly 100.

[0024] In this embodiment, the first and second rotating blocks 210 and 220 are attached to the bracket assembly 100 by the second rotating block 220 engaging with the first rotating block 210 via the first engaging block 230, and the clamping assembly 300 is attached to the second rotating block 220 via the mounting groove 221 and the engaging groove 222.

[0025] Specifically, the first engaging block 230 penetrates the bracket assembly 100, so that the first rotating block 210 and the second rotating block 220 are provided on both sides of the bracket assembly 100, and the first rotating block 210 and the second rotating block 220 are rotatable relative to the bracket assembly 100. This allows for adjustment of the angle of the seat-mounted fan 400 when the clamping assembly 300 is fixed.

[0026] Furthermore, there are two first engagement blocks 230, arranged in an L-shape, and they are symmetrically positioned on the side of the second rotating block 220 away from the mounting groove 221 and engagement groove 222. When the first rotating block 210 and the second rotating block 220 are mounted together, the projection of the first engagement block 230 is in close contact with the first rotating block 210.

[0027] Furthermore, the first engagement block 230 has a sloped surface, and when the first engagement block 230 enters the engagement hole 211, the sloped surface contacts the edge of the engagement hole 211, deforming the first engagement block 230, and when the first engagement block 230 penetrates the engagement hole 211, the first engagement block 230 returns to its original shape, thereby engaging the first rotating block 210 and the second rotating block 220.

[0028] Specifically, the first engagement block 230 is made of plastic material and deforms when subjected to external pressure, returning to its original shape when the pressure is released, thereby ensuring that the first rotating block 210 and the second rotating block 220 engage with each other via the first engagement block 230.

[0029] As shown in Figures 1 and 2, in one embodiment, Bracket assembly 100 is A mounting plate 110 is provided on the seat-mounted fan 400, and has mounting holes 111 for attaching the first rotating block 210 and the second rotating block 220, and the first engaging block 230 penetrates the mounting hole 111 and engages with the engaging hole 211, The system includes a support member 120 provided on the mounting plate 110 and rotating relative to the mounting plate 110.

[0030] In this embodiment, the mounting plate 110 has mounting holes 111, and the first engagement block 230 penetrates the mounting plate 110 and engages with the engagement holes 211.

[0031] Of these, the mounting holes 111 are slightly recessed relative to the surface of the mounting plate 110, thereby ensuring that when the second rotating block 220 is attached to the mounting plate 110, the step difference between it and the surface of the mounting plate 110 is relatively small.

[0032] Specifically, the length of the first engagement block 230 is matched to the thickness of the mounting plate 110, thereby preventing vertical rattling after the first rotation block 210 and the second rotation block 220 are attached to the mounting plate 110.

[0033] Specifically, the first rotating block 210 has multiple wavy protrusions arranged in an annular pattern on the first rotating block 210, and the mounting plate 110 is provided with wavy grooves 113 that fit the multiple protrusions.

[0034] Multiple protrusions fit into the corrugated groove 113, and as the first rotating block 210 and the second rotating block 220 rotate relative to the mounting plate 110, different protrusions engage with the corrugated groove 113, thereby limiting the angle of rotation of the clamping assembly 300 relative to the mounting plate 110.

[0035] What needs to be explained is that the first engagement block 230 has a certain degree of elasticity, and when the first rotating block 210 rotates, the multiple protrusions rotate in close contact with the wavy groove 113, and at this time the first engagement block 230 deforms slightly, thereby ensuring that the first rotating block 210 can rotate relative to the mounting plate 110.

[0036] Furthermore, the diameters of the first rotating block 210 and the second rotating block 220 are larger than the diameter of the mounting hole 111, thereby preventing the first rotating block 210 and the second rotating block 220 from detaching from the mounting plate 110.

[0037] As shown in Figures 2 to 6, in one embodiment, The clamping assembly 300 is A clip 310 is detachably provided on the second rotating block 220, and the clip 310 has a non-slip silicone on its clamping plate, A limiting block 320 provided on the clip 310, wherein when the clip 310 is attached to the second rotating block 220, the limiting block 320 is located within the mounting groove 221, The clip 310 includes a second engaging block 330 which engages with an engaging groove 222 when the clip 310 is attached to a second rotating block 220.

[0038] In this embodiment, the number of mounting grooves 221 and limiting blocks 320 is preferably set to two, with the mounting groove 221 having an opening on one side. During installation, the limiting block 320 at the bottom of the clip 310 is pushed into the mounting groove 221 through the opening, and then pushed forward to move the limiting block 320 along the engagement groove 222, continuing until the second engagement block 330 engages with the engagement groove 222, thereby completing the attachment of the clip 310 to the second rotation block 220.

[0039] Specifically, the second engagement block 330 has a locking portion 331 and a shift block 332. When the clip 310 is attached to the second rotation block 220, the locking portion 331 is located within the engagement groove 222. The shift block 332 is provided to disengage the locking portion 331 from the engagement groove 222.

[0040] The second engagement block 330 is provided on the clip 310, is made of plastic, and has a certain degree of elasticity. When it is necessary to remove the clip 310, the clip 310 can be removed from the second rotation block 220 simply by lifting the shift block 332 upward to deform the second engagement block 330 and then disengaging the locking portion 331 from the engagement groove 222.

[0041] Clip 310 is a common clip on the market (e.g., A-shaped clip, spring clip, etc.), and its structure consists of two clamping plates with a torsion spring between them.

[0042] The clamping plate of the clip 310 has anti-slip silicone, and by providing the anti-slip silicone, the frictional force of the clip 310 is increased, and furthermore, the clip 310 is prevented from falling off.

[0043] As shown in Figure 5, in one embodiment, the clamping structure is The device further includes a limiting projection 321 provided on a limiting block 320 having a trapezoidal cross-section.

[0044] In this embodiment, the limiting projection 321 is provided on the limiting block 320. When the limiting block 320 enters the mounting groove 221, the limiting projection 321 closes the opening of the mounting groove 221, thereby preventing excessive insertion of the limiting block 320.

[0045] The cross-section of the limiting block 320 has a trapezoidal structure, thereby preventing the limiting block 320 from detaching from the top of the mounting groove 221.

[0046] Preferably, the limiting block 320 can also be configured as an inverted T-shape or an inverted L-shape.

[0047] As shown in Figure 2, in one embodiment, The cross-section of the support member 120 is U-shaped, both ends of the support member 120 rotate relative to the mounting plate 110, the support member 120 has a limiting groove 121, and the mounting plate 110 has a projection 112 that fits into the limiting groove 121.

[0048] In this embodiment, the support member 120 has two limiting grooves 121 at both ends, and the mounting plate 110 has protrusions 112 on both sides that fit into the limiting grooves 121. The support member 120 is fixed to the mounting plate 110 at two angles by the engagement of the two different limiting grooves 121 on the same side with the corresponding protrusions 112. In the initial state, the support member 120 and the mounting plate 110 are installed horizontally, and in this case, the protrusions 112 are located in one of the limiting grooves 121. When the support member 120 and the mounting plate 110 are at a predetermined angle, the protrusions 112 are located in the other limiting groove 121.

[0049] Furthermore, elastic members are provided on both sides of the mounting plate 110, and the protrusions 112 are provided on the elastic members to ensure that the support member 120 is rotatable. At the same time, the elastic members provide a locking restriction on the support member 120.

[0051] In this embodiment, when the clamping structure is removed from the casing 410, the waist-mounted fan 400 can be used handheld by hanging it around the neck or wrist by connecting it to a neck strap or hand strap via the suspension holes in the casing 410.
