Description

Technical Field

[0001] This utility model relates to the field of fan technology, and more specifically, to a gripper structure and a portable fan. Background Technology

[0002] Portable fans, also known as handheld fans, are small and lightweight, fulfilling the need for portability to a certain extent. Clip-on fans, in particular, can be both movable and fixed in place, making them suitable for various scenarios and especially popular.

[0003] Currently, the clamping structure of most clamping fans on the market is usually a press-type. That is, with the help of a torsion spring, pressing the pressing part opens the two clamps, and releasing the pressing part clamps the two clamps onto the object. This type of press-type clamping fan is usually used for clamping flat surfaces such as desktops, so the opposite surfaces of the two clamps are usually set to be flat. However, this design is not suitable for clamping rod-shaped structures, such as the guardrails of strollers or bed rails, which limits the usage scenarios. Moreover, this type of press-type clamping fan mainly relies on the torsion spring to clamp onto the object. Not only is the clamping force weak and the firmness not high, but the torsion spring is also prone to damage after repeated pressing and use, causing the clamping to fail and affecting the user experience.

[0004] To better secure fans to rod-shaped objects such as stroller railings, portable fans with octopus-like silicone feet have appeared on the market. These octopus-like silicone feet can bend, making it very convenient to fix the fan to the rod-shaped object. However, this method of fixing is not very secure because it only relies on the bending and wrapping of the octopus-like silicone feet. When used outdoors, bumps or accidental touches often cause the fan to tilt or fall off. This not only easily changes the direction of the fan's airflow, affecting the user experience, but also poses a certain danger to children or infants. Utility Model Content

[0005] One objective of this utility model is to provide a clamping claw structure that is firm and not easily damaged, so as to solve the problems in the prior art. Another objective of this utility model is to provide a portable fan.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a gripper structure, including a fixed gripper, a movable gripper, and an adjustment assembly. The movable gripper is rotatably connected to the fixed gripper. The adjustment assembly includes a moving block and a driving member connected to the moving block. The driving member is used to drive or move the moving block. The moving block is movably engaged with the movable gripper. When the driving member drives or moves the moving block, the moving block can drive the movable gripper to rotate. When the driving member drives or moves the moving block in the opposite direction, the moving block can drive the movable gripper to rotate in the opposite direction.

[0007] The movable clamping component of this utility model is rotatably connected to the fixed clamping component. The movable clamping component is movably engaged with the moving block. During the process of the driving component driving or moving the moving block to move or move in the opposite direction, the moving block can drive the movable clamping component to rotate or rotate in the opposite direction, thereby adjusting the opening degree between the movable clamping component and the fixed clamping component.

[0008] This invention uses a driving component to move a movable block. During this movement, the movable block rotates a movable clamping component, adjusting the opening size between the movable and fixed clamping components. This allows the gripper structure to clamp objects of different sizes. The movable block is driven by the driving component; when it is not moving, its position is locked, meaning the opening size between the movable and fixed clamping components is locked when the movable block is stationary. The gripper structure of this invention features a stable and durable fit, making it less prone to damage. Furthermore, the gripper structure provides a more secure grip on tabletops or rod-shaped objects, enhancing safety and reliability.

[0009] Furthermore, the movable clamping component includes an assembly part, which has a slot, and the movable block is movably engaged in the slot; when the movable block moves, the movable block can abut against the side wall of the slot, thereby driving the movable clamping component to rotate.

[0010] Furthermore, the driving member is rotatably connected to the fixed clamping member and axially limited to the fixed clamping member; the driving member includes a screw portion, the screw portion is provided with an external thread, the moving block is sleeved on the screw portion, the moving block is threadedly connected to the screw portion, and the circumferential rotation of the moving block is limited to the screw portion.

[0011] Furthermore, the slot is configured as a U-shaped groove located at the end of the assembly part, and the moving block is movably engaged in the U-shaped groove.

[0012] Furthermore, the slot is configured as a strip-shaped groove extending from one end of the assembly part, and the moving block includes a snap-fit ​​part, which is movably snapped into the strip-shaped groove.

[0013] Furthermore, when the slot rotates with the movable clamping member to directly above the rotation center line of the movable clamping member, the bottom end of the moving block abuts against or is spaced from the bottom of the slot.

[0014] Furthermore, the screw portion is located at the middle position of the end of the assembly portion, and the slot or the assembly portion is provided with a notch for the screw portion to pass through.

[0015] Furthermore, the fixed clamping member has an internal mounting cavity, in which the moving block, the screw part, and part of the assembly part are all located. The fixed clamping member has an assembly port for the assembly part to extend into.

[0016] Furthermore, the drive component also includes a handle, which is fixedly connected to the end of the screw portion, and the handle is at least partially located outside the fixed clamping component.

[0017] A portable fan includes a fan body and the aforementioned clamping structure, wherein the fan body is mounted on the fixing clamp.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] (1) This utility model drives or moves the moving block by a driving component. During the movement of the moving block, the movable clamping component rotates, thereby adjusting the opening size of the movable clamping component and the fixed clamping component. This allows the gripper structure to clamp objects of different sizes. The driving component and the moving block are well-matched, not easily damaged, and have a longer service life.

[0020] (2) The movable block and the screw part of this utility model are connected by threads. When the screw part does not rotate, the position of the movable block can be locked, that is, the size of the opening between the movable clamping part and the fixed clamping part can be locked, so that the clamping structure can be firmly clamped on the corresponding object, and it is not easy to tilt or fall off, making it safer and more reliable to use.

[0021] (3) The adjustment component of this utility model is hidden inside the fixed clamping component, which can not only reduce the damage of the adjustment component, but also save design space, making the overall structure of the clamping structure more compact, and also greatly improving the external aesthetics of the clamping structure.

[0037] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0038] Example 1

[0039] This embodiment is an example 1 of a gripper structure, such as... Figure 1 and Figure 2As shown, the gripper structure in this embodiment includes a fixed gripper 11, a movable gripper 12, and an adjustment assembly 13. The movable gripper 12 is rotatably connected to the fixed gripper 11. When the movable gripper 12 rotates, the opening between the movable gripper 12 and the fixed gripper 11 can be adjusted, allowing the gripper structure to be clamped onto the object to be installed. The object can be a planar structure, such as a tabletop, or a rod-like structure, such as a stroller rail or a bed rail. It should be noted that the objects that can be installed with the gripper structure in this embodiment are merely illustrative and are not intended to limit the use of the gripper structure.

[0040] The adjusting component 13 is used to drive the movable clamping member 12 to rotate. The opening degree between the fixed clamping member 11 and the movable clamping member 12 can be adjusted by the adjusting component 13, so that the clamping structure can be firmly clamped on the object to be installed.

[0041] Specifically, in this embodiment, the adjusting component 13 includes a movable block 131 and a driving member 132. The driving member 132 is connected to the movable block 131 and is used to drive or move the movable block 131. The movable block 131 is movably engaged with the movable clamping member 12. Specifically, the movable clamping member 12 is provided with a slot 123, and the movable block 131 is movably engaged in the slot 123 of the movable clamping member 12. When the driving member 132 drives or moves the movable block 131, the movable block 131 can drive the movable clamping member 12 to rotate during the movement. When the driving member 132 drives or moves the movable block 131 in the opposite direction, the movable block 131 can drive the movable clamping member 12 to rotate in the opposite direction during the movement. When the movable clamping member 12 rotates, it can change the opening size between the fixed clamping member 11 and the movable clamping member 12.

[0042] As a preferred technical solution, such as Figure 4 and Figure 5 As shown, in this embodiment, the driving component 132 is rotatably connected to the fixed clamping component 11, and the driving component 132 is axially limited on the fixed clamping component 11. This means the driving component 132 cannot move along its axial direction. In this embodiment, the driving component 132 includes a screw portion 134 with an external thread. The moving block 131 has a threaded through hole and is sleeved on the screw portion 134. The moving block 131 is threadedly connected to the screw portion 134, and its circumferential rotation is limited on the screw portion 134, meaning the moving block 131 cannot follow the screw portion 134 in circumferential rotation.

[0043] When the screw part 134 is rotated, since the moving block 131 is threadedly connected to the screw part 134 and cannot rotate circumferentially with the screw part 134, the moving block 131 can move axially along the screw part 134. During the axial movement of the moving block 131 along the screw part 134, since the moving block 131 is engaged in the slot 123 of the movable clamping member 12, the moving block 131 can abut against the side wall of the slot 123 and thus rotate the movable clamping member 12, thereby achieving the purpose of adjusting the opening size of the movable clamping member 12 and the fixed clamping member 11.

[0044] In other embodiments, the drive unit 132 can be configured as an electric telescopic rod or other electric drive device, and the moving block 131 is connected to the output end of the drive unit 132, so that the moving block 131 can be moved directly by the drive unit 132.

[0045] In this embodiment, the fixing clamp 11 is configured as a split structure, such as... Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, the fixing clamp 11 is set in an upper and lower split configuration. Specifically, it includes a body part 111 and a cover part 112. The body part 111 is provided with a mounting cavity 118. In this embodiment, the mounting cavity 118 is formed by the top of the body part 111 being recessed downwards, and the cover part 112 covers the top of the body part 111.

[0046] In this embodiment, the moving block 131 and the screw part 134 are both located in the mounting cavity 118. By placing the moving block 131 and the screw part 134 in the mounting cavity 118 of the main body part 111, and then covering the main body part 111 with the cover part 112, the adjustment component 13 can be hidden inside the fixed clamping member 11. This not only reduces the damage to the adjustment component 13 and improves the service life of the adjustment component 13, but also saves design space, making the overall structure of the gripper structure more compact, and also greatly improving the external aesthetics of the gripper structure.

[0047] like Figure 5 As shown, the main body 111 is also provided with a plurality of hollow cavities 117 at intervals. The hollow cavities 117 can reduce the overall weight of the gripper structure, making the gripper structure lighter and easier to carry.

[0048] In other embodiments, the fixing clamp 11 may also be a left and right split type, specifically including a two-half cavity docking structure, that is, it is formed by docking two half cavity docking structures. When the left and right half cavity docking structures are docked together, an installation cavity 118 can be formed inside the fixing clamp 11.

[0049] Specifically, such as Figure 4 and Figure 5As shown, the drive component 132 also includes a limiting part 137 and a handle 138. The screw part 134 passes through the mounting cavity 118, and one end of the screw part 134 extends into the hollow cavity 117 adjacent to the mounting cavity 118. The limiting part 137 is connected to the end of the screw part 134 located in the hollow cavity 117. In this embodiment, the limiting part 137 is a nut, and the nut is threadedly connected to the end of the screw part 134.

[0050] A handle 138 is fixedly connected to the other end of the screw portion 134. The handle 138 is at least partially located on the outside of the body portion 111; in this embodiment, the entire handle 138 is located on the outside of the body portion 111. The handle 138 facilitates user operation, and rotating the handle 138 causes the screw portion 134 to rotate. In this embodiment, the screw portion 134 is axially limited on the fixed clamping member 11 by the limiting portion 137 and the handle 138.

[0051] As a preferred technical solution, in this embodiment, bearings 139 are provided between the limiting part 137 and the outer wall of the mounting cavity 118, and between the handle 138 and the outer wall of the mounting cavity 118. The provision of bearings 139 can improve the stability of the rotation of the drive component 132.

[0052] In this embodiment, the user rotates the handle 138 to drive the screw part 134 to rotate. In other embodiments, the screw part 134 can be directly driven by an electric drive device such as a motor or driven to rotate in conjunction with other transmission structures.

[0053] like Figure 5 As shown, in this embodiment, the main body 111 has a rectangular block structure, and two extension blocks 113 extend outward from the two opposite sidewalls of the main body 111. In this embodiment, the extension blocks 113 are semi-circular arc-shaped. As a preferred technical solution, in this embodiment, the two extension blocks 113 and the main body 111 are integrally formed.

[0054] In this embodiment, the shape of the cover portion 112 matches the shape of the main body portion 111 and the two extension blocks 113, and the cover portion 112 is detachably connected to the top of the main body portion 111. Specifically, the cover portion 112 is detachably connected to the main body portion 111 through one or more of the following methods: snap-fit, plug-in, threaded connection, screw connection, magnetic attraction, etc. The above-mentioned detachable connection methods are merely examples and are not intended to limit the present invention.

[0055] As a preferred technical solution, in this embodiment, the cover portion 112 is detachably and fixedly installed on the top of the body portion 111 using screws. To further facilitate convenient, quick, and accurate installation of the cover portion 112 onto the body portion 111, in this embodiment, the body portion 111 and the cover portion 112 achieve rapid positioning and docking through a positioning structure.

[0056] Specifically, in this embodiment, the positioning structure includes a first positioning groove 141 and a first positioning post 142, wherein the first positioning groove 141 is disposed on the extension block 113, such as... Figure 7 As shown, the first positioning post 142 is located at the bottom of the cover part 112. By positioning and inserting the first positioning post 142 and the first positioning groove 141, the cover part 112 can be quickly and accurately closed onto the body part 111.

[0057] As a preferred technical solution, in this embodiment, the screws used to connect the body portion 111 and the cover portion 112 are located at the positions of the first positioning groove 141 and the first positioning post 142. When the first positioning post 142 is inserted into the first positioning groove 141, a stable connection between the cover portion 112 and the body portion 111 is achieved by the screws.

[0058] like Figure 2 As shown, the bottom of the main body 111 is provided with an assembly port 119, which is connected to the mounting cavity 118. A part of the movable clamping member 12 extends into the mounting cavity 118 through the assembly port 119 and engages with the moving block 131.

[0059] like Figure 2 and Figure 4 As shown, in this embodiment, the fixing clamp 11 further includes mounting ears 114, which are used for assembly connection with the movable clamp 12. In this embodiment, two mounting ears 114 are provided, which are respectively arranged opposite to each other on both sides of the bottom mounting opening 119 of the main body 111. As a preferred technical solution, in this embodiment, the mounting ears 114 and the main body 111 are integrally formed.

[0060] To facilitate the gripper structure's attachment to rod-shaped objects, such as stroller guardrails or crib rails, etc. Figure 1 and Figure 2 As shown, in this embodiment, the bottom of the main body 111 is also provided with a first arc-shaped recess 115. The arc-shaped surface of the first arc-shaped recess 115 can better fit with the surface of the rod-shaped object, thereby improving the clamping firmness of the fixing clamp 11 on the rod-shaped structure.

[0061] As a preferred technical solution, such as Figure 1 and Figure 2 As shown, in this embodiment, the main body 111 has an inclined surface 116 at the end of the gripper structure opening. The inclined surface 116 can serve as a guide, making it easy for the rod-shaped structure to enter the gripper structure opening along the inclined surface 116, thereby enabling the gripper structure 1 to be clamped onto the rod-shaped structure conveniently and quickly.

[0062] like Figure 6As shown, in this embodiment, the movable clamping member 12 includes a clamping part 121 and an assembly part 122. The clamping part 121 is disposed opposite to the bottom of the main body part 111 and is used to clamp an object. In this embodiment, the clamping part 121 has a second arc-shaped recess 128 on the side facing the fixed clamping member 11. The arc-shaped surface of the second arc-shaped recess 128 can better fit with the surface of the rod-shaped object, thereby improving the clamping firmness of the movable clamping member 12 on the rod-shaped structure.

[0063] The assembly part 122 is rotatably connected to the two assembly ears 114 via a pivot 126. As a preferred embodiment, the pivot 126 is located at the end of the assembly part 122 near the clamping part 121.

[0064] One end of the assembly part 122 is fixedly connected to the clamping part 121, and the other end extends into the mounting cavity 118 through the assembly port 116 and engages with the moving block 131. As a preferred technical solution, in this embodiment, the assembly part 122 and the clamping part 121 are integrally formed. Of course, the assembly part 122 and the clamping part 121 can also be a detachable and separate structure.

[0065] like Figure 4 and Figure 6 As shown, the end of the assembly portion 122 of the movable clamping member 12 that extends into the mounting cavity 118 is provided with a slot 123. Specifically, the slot 123 can be directly formed on the end of the assembly portion 122, or it can be other structures with slots 123 fixedly formed on the end of the assembly portion 122. In the embodiment, the slot 123 is directly formed on the end of the assembly portion 122.

[0066] In this embodiment, the slot 123 is a U-shaped groove, and the moving block 131 has a columnar structure, with the moving block 131 engaging within the U-shaped groove. As a preferred technical solution, in this embodiment, the screw portion 134 is located at the middle position of the end of the assembly portion 122, and both opposite sidewalls of the U-shaped groove have notches 124 for the screw portion 134 to pass through. The structural arrangement of the slot 123 in this embodiment does not affect the axial movement of the moving block 131 along the screw portion 134, and during movement, the moving block 131 can actuate the end of the assembly portion 122, thereby driving the movable clamping member 12 to rotate, achieving the purpose of adjusting the opening size between the fixed clamping member 11 and the movable clamping member 12.

[0067] like Figure 4 and Figure 5As shown, in this embodiment, the fixing clamp 11 is provided with a limiting member 133 for restricting the circumferential rotation of the moving block 131. Specifically, in this embodiment, the limiting member 133 is a limiting rail provided on the inner sidewall of the mounting cavity 118 and arranged axially along the screw portion 134. In this embodiment, two sets of limiting rails are provided, and the two sets of limiting rails are respectively located on two opposite inner sidewalls of the mounting cavity 118, and the two ends of the moving block 131 are respectively slidably limited within the two sets of limiting rails.

[0068] Specifically, in this embodiment, the limiting rail includes an upper rail 1331 and a lower rail 1332. The upper rail 1331 and the lower rail 1332 are arranged vertically on the inner sidewall of the mounting cavity 118, and there is a first gap 1333 between the upper rail 1331 and the lower rail 1332. The end of the moving block 131 is slidably located within the first gap 1333. The upper rail 1331 and the lower rail 1332 can not only restrict the rotation of the moving block 131, but also provide a sliding track for the moving block 131, so that the moving block 131 can move steadily along the axial direction of the screw part 134.

[0069] In this embodiment, one end of the upper rail 1331 is spaced from the side wall of the mounting cavity 118, which facilitates the assembly of the moving block 131 within the limiting rail. As a preferred technical solution, the upper limiting rail 1331 is provided with a guide angle 1334. The design of the guide angle 1334 is beneficial to improving the ease of assembly and efficiency of the moving block 131 and the limiting member 133.

[0070] When the slot 123 rotates with the movable clamping member 12 to be directly above the rotation center line of the movable clamping member 12, that is, when the slot 123 is directly above the rotating shaft 126, the bottom end of the moving block 131 abuts against or is spaced from the bottom of the slot 123. This arrangement allows the moving block 131 to move a large range on the screw part 134, thereby ensuring that the movable clamping member 12 has a large range of opening and closing.

[0071] To prevent the movable block 131 from dislodging from the slot 123 of the movable clamping member 12, the fixed clamping member 11 also needs to be provided with a limiting structure to restrict the axial displacement range of the movable block 131 or the rotation range of the movable clamping member 12. In this embodiment, the rotation range of the movable clamping member 12 is limited by designing the opening width of the assembly port 119 along the axial direction of the screw portion 134, which avoids the need for additional structures, reduces costs, and greatly improves the simplicity of the gripper structure design. Of course, in other embodiments, a limiting block can also be provided on the fixed clamping member 11 to limit the axial movement range of the movable block 131 or the rotation range of the movable clamping member 12.

[0072] Regardless of the type of limiting structure used to restrict the axial displacement range of the moving block 131 or the rotation range of the movable clamping member 12, it must be ensured that when the moving block 131 moves to the maximum or minimum displacement or the movable clamping member 12 rotates to the minimum or maximum angle, the moving block 131 cannot be completely dislodged from the slot 123.

[0073] As a preferred technical solution, such as Figure 2 As shown, in this embodiment, the bottom of the movable clamping member 12 is provided with a plurality of strip-shaped grooves 125 at intervals. The grooves 125 not only save materials and reduce costs, but also reduce the weight of the clamping structure itself.

[0074] This utility model adjusts the opening size between the movable clamping member 12 and the fixed clamping member 11 by cooperating with the movable block 131 and the screw part 134, which makes it easy for the claw structure to clamp objects of different sizes. Moreover, the fit between the various parts of the structure is stable, not easy to be damaged, and has a longer service life.

[0075] In use, rotate handle 138 to adjust the opening of the gripper structure. When the opening of the gripper structure is placed on the object to be installed, rotate handle 138 again to reduce the opening of the gripper structure, thus securing the gripper structure to the object. Since the moving block 131 and the screw part 134 are threadedly connected, the position of the moving block 131 can be locked when the screw part 134 is not rotating. That is, the opening size between the movable clamping member 12 and the fixed clamping member 11 can be locked, thereby ensuring that the gripper structure is firmly clamped on the corresponding object. The gripper structure is not easy to tilt or fall off, making it safer and more reliable to use.

[0076] Example 2

[0077] This embodiment is a second embodiment of a gripper structure, such as... Figure 8 As shown, the gripper structure in this embodiment includes a fixed gripper 11, a movable gripper 12, and an adjustment assembly 13. The movable gripper 12 is rotatably connected to the fixed gripper 11. When the movable gripper 12 rotates, the opening between the movable gripper 12 and the fixed gripper 11 can be adjusted, allowing the gripper structure to be clamped onto the object to be installed. The object can be a planar structure, such as a tabletop, or a rod-like structure, such as a stroller rail or a bed rail. It should be noted that the objects that can be installed with the gripper structure in this embodiment are merely illustrative and are not intended to limit the use of the gripper structure.

[0078] The adjusting component 13 is used to drive the movable clamping member 12 to rotate. The opening degree between the fixed clamping member 11 and the movable clamping member 12 can be adjusted by the adjusting component 13, so that the clamping structure can be firmly clamped on the object to be installed.

[0079] Specifically, such as Figure 9 and Figure 10 As shown, in this embodiment, the adjusting component 13 includes a movable block 131 and a driving member 132. The driving member 132 is connected to the movable block 131 and is used to drive the movable block 131 to move. The movable block 131 is movably engaged with the movable clamping member 12. Specifically, the movable clamping member 12 is provided with a slot 123, and the movable block 131 is movably engaged in the slot 123 of the movable clamping member 12. When the driving member 132 drives the movable block 131 to move, the movable block 131 can drive the movable clamping member 12 to rotate during the movement. When the driving member 132 drives or drives the movable block 131 to move in the opposite direction, the movable block 131 can drive the movable clamping member 12 to rotate in the opposite direction during the movement. When the movable clamping member 12 rotates, it can change the opening size between the fixed clamping member 11 and the movable clamping member 12.

[0080] In this embodiment, the driving component 132 is rotatably connected to the fixed clamping component 11, and the driving component 132 is axially limited on the fixed clamping component 11. This means the driving component 132 cannot move along its axial direction. In this embodiment, the driving component 132 includes a screw portion 134 with an external thread. A moving block 131 has a threaded through hole and is sleeved on the screw portion 134. The moving block 131 is threadedly connected to the screw portion 134, and its circumferential rotation is limited on the screw portion 134, meaning the moving block 131 cannot follow the screw portion 134 in circumferential rotation.

[0081] When the screw part 134 is rotated, since the moving block 131 is threadedly connected to the screw part 134 and cannot rotate circumferentially with the screw part 134, the moving block 131 can move axially along the screw part 134. During the axial movement of the moving block 131 along the screw part 134, since the moving block 131 is engaged in the slot 123 of the movable clamping member 12, the moving block 131 can abut against the side wall of the slot 123 and thus rotate the movable clamping member 12, thereby achieving the purpose of adjusting the opening size of the movable clamping member 12 and the fixed clamping member 11.

[0082] In this embodiment, the fixing clamp 11 is configured as a split structure, such as... Figure 9 and Figure 10As shown, in this embodiment, the fixing clamp 11 includes a body portion 111 and a cover portion 112. The body portion 111 has an opening at its top, and the cover portion 112 covers the top of the body portion 111. The cover portion 112 is detachably connected to the body portion 111 through one or more of the following methods: snap-fit, insertion, threaded connection, screw connection, magnetic attraction, etc. The above-mentioned detachable connection methods are merely examples and are not intended to limit the present invention. As a preferred technical solution, in this embodiment, the cover portion 112 is inserted into the top of the body portion 111.

[0083] The main body 111 has a mounting cavity 118, and the moving block 131 and the screw part 134 are both located in the mounting cavity 118. By placing the moving block 131 and the screw part 134 in the mounting cavity 118 of the main body 111, and then covering the main body 111 with the cover part 112, the adjustment component 13 can be hidden inside the fixed clamping member 11. This not only reduces the damage to the adjustment component 13 and improves the service life of the adjustment component 13, but also saves design space, making the overall structure of the gripper structure more compact, and also greatly improving the external aesthetics of the gripper structure.

[0084] like Figure 9 As shown, in this embodiment, the bottom shape of the body part 111 is similar to a wave shape “~”, wherein the position of the wave peak at the bottom of the body part 111 is the clamping part of the body part 111. In this embodiment, the bottom of the clamping part of the body part 111 includes a first arc-shaped recess 115. The arc-shaped surface of the first arc-shaped recess 115 can better fit with the surface of the rod-shaped object, thereby improving the clamping firmness of the fixing clamp 11 on the rod-shaped structure.

[0085] In this embodiment, the mounting cavity 118 is located at the trough position at the bottom of the main body 111. For example... Figure 9 and Figure 10 As shown, the driving component 132 also includes a limiting part 137 and a handle 138. A screw part 134 passes through the mounting cavity 118, with one end extending into the mounting cavity 118. The end of the screw part 134 extending into the mounting cavity 118 is fixedly connected to the limiting part 137, and the other end of the screw part 134 is fixedly connected to the handle 138. The handle 138 is located outside the body part 111. The handle 138 facilitates user operation; rotating the handle drives the screw part 134 to rotate. As a preferred technical solution, in this embodiment, the handle 138 is provided with anti-slip ridges 1381, which further facilitates user rotation of the handle 138.

[0086] In this embodiment, the driving member 132 is axially limited on the fixed clamping member 11 by the limiting part 137. As a preferred technical solution, in this embodiment, the limiting part 137 and the screw part 134 are configured as a single molded structure.

[0087] like Figure 9 and Figure 10 As shown, the mounting cavity 118 is provided with a mounting support 151, and a limiting member 152 is detachably provided on the mounting support 151. In this embodiment, the limiting member 152 is fixed to the mounting support 151 by screws. Of course, in other embodiments, the limiting member 152 can also be connected to the mounting support 151 by other fixing methods.

[0088] like Figure 10 and 11 As shown, the limiting member 152 is provided with a limiting notch 153, and the limiting part 137 includes a limiting insertion part 1371 that can be inserted into the limiting notch 153. When the limiting insertion part 1371 is inserted into the limiting notch 153, the limiting part 134 can be axially limited on the limiting member 152, thereby axially limiting the screw part 134 on the fixed clamping member 11, so that the screw part 134 cannot move along its axial direction.

[0089] like Figure 9 As shown, the bottom of the main body 111 is provided with an assembly port 119, which is connected to the mounting cavity 118. A part of the movable clamping member 12 extends into the mounting cavity 118 through the assembly port 119 and is assembled with the moving block 131.

[0090] like Figure 12 As shown, in this embodiment, the movable clamping member 12 includes a clamping part 121 and an assembly part 122. The clamping part 121 is disposed opposite to the bottom of the main body part 111 and is used to clamp an object. In this embodiment, the clamping part 121 has a second arc-shaped recess 128 on the side facing the fixed clamping member 11. The arc-shaped surface of the second arc-shaped recess 128 can better fit with the surface of the rod-shaped object, thereby improving the clamping firmness of the movable clamping member 12 on the rod-shaped structure.

[0091] The assembly part 122 is rotatably connected to the main body part 111 via a rotating shaft 126. As a preferred embodiment, the rotating shaft 126 is located at the middle position of the assembly part 122. One end of the assembly part 122 is fixedly connected to the clamping part 121, and the other end extends through the assembly port 119 into the mounting cavity 118 to engage with the moving block 131. As a preferred embodiment, in this case, the assembly part 122 and the clamping part 121 are integrally formed; however, the assembly part 122 and the clamping part 121 can also be detachable and separate structures.

[0092] In this embodiment, the end of the assembly portion 122 of the movable clamping member 12 that extends into the mounting cavity 118 is provided with a slot 123. Specifically, the slot 123 can be directly formed on the end of the assembly portion 122, or it can be other structures with slot 123 fixedly formed on the end of the assembly portion 122. In this embodiment, the slot 123 is directly formed on the end of the assembly portion 122.

[0093] like Figure 12 As shown, in this embodiment, the assembly part 122 includes two mounting blocks 127 arranged at relative intervals. The inner sidewalls of the two mounting blocks 127 are provided with slots 123. The slots 123 are strip-shaped grooves extending out of the mounting blocks 127 at one end. The two ends of the moving block 131 are respectively provided with engaging parts 136, which are movably engaged in the strip-shaped grooves.

[0094] As a preferred technical solution, in this embodiment, the outer side wall of the snap-fit ​​part 136 is disposed adjacent to the inner side wall of the strip groove, but the snap-fit ​​part 136 can still move along the length direction of the strip groove within the strip groove.

[0095] In this embodiment, the screw portion 134 is located at the middle position of the end of the assembly portion 122, and the gap between the two mounting blocks 127 forms a notch through which the screw portion 134 passes. In this embodiment, the structural arrangement of the slot 123 and the mounting portion 122 does not affect the axial movement of the moving block 131 along the screw portion 134, and the moving block 131 can move the end of the assembly portion 122 during movement, thereby driving the movable clamping member 12 to rotate, so as to adjust the opening size between the fixed clamping member 11 and the movable clamping member 12.

[0096] In this embodiment, the slot 123 is set as a strip-shaped slot, which not only allows the moving block 131 to move the assembly part 122 during the movement, but also restricts the circumferential rotation of the moving block 131, that is, the moving block 131 cannot follow the screw part 134 to rotate circumferentially, which greatly simplifies the structure.

[0097] When the slot 123 rotates with the movable clamping member 12 to be directly above the rotation center line of the movable clamping member 12, that is, when the slot 123 is directly above the axis of the rotating shaft 126, the bottom end of the moving block 131 abuts against or is spaced from the bottom of the slot 123. This arrangement allows the moving block 131 to move within a large range on the screw portion 134, thereby ensuring that the movable clamping member 12 has a large range of opening and closing.

[0098] To prevent the movable block 131 from dislodging from the slot 123 of the movable clamping member 12, the fixed clamping member 11 also needs to be provided with a limiting structure to restrict the axial displacement range of the movable block 131 or the rotation range of the movable clamping member 12. In this embodiment, the rotation range of the movable clamping member 12 is limited by designing the opening width of the assembly port 119 along the axial direction of the screw portion 134. At the same time, in this embodiment, an abutment block 154 is also provided on the inner wall of the mounting cavity 118 at the assembly port. When the movable clamping member 12 rotates to the minimum or maximum opening position, the abutment block 154 can provide abutment support and limit the movement of the movable clamping member 12.

[0099] Regardless of the type of limiting structure used to restrict the axial displacement range of the moving block 131 or the rotation range of the movable clamping member 12, it must be ensured that when the moving block 131 moves to the maximum or minimum displacement or the movable clamping member 12 rotates to the minimum or maximum angle, the moving block 131 cannot be completely dislodged from the slot 123.

[0100] As a preferred technical solution, in this embodiment, anti-slip pads 155 are provided at both the first arc-shaped recess 115 of the fixed clamping member 11 and the second arc-shaped recess 128 of the movable clamping member 12. The anti-slip pads 155 are provided to increase the friction between the gripper structure and the object to be installed, thereby improving the stability of the gripper structure. In this embodiment, the anti-slip pads 155 can be silicone pads, rubber pads, or other elastic soft pads made of other materials. As a preferred technical solution, in this embodiment, the outer surface of the anti-slip pads 155 is wavy, which is beneficial to further improve the stability of the gripper structure.

[0101] This utility model adjusts the opening size between the movable clamping member 12 and the fixed clamping member 11 by cooperating with the movable block 131 and the screw part 134, which makes it easy for the claw structure to clamp objects of different sizes. Moreover, the fit between the various parts of the structure is stable, not easy to be damaged, and has a longer service life.

[0102] In use, rotate handle 138 to adjust the opening of the gripper structure. When the opening of the gripper structure is placed on the object to be installed, rotate handle 138 again to reduce the opening of the gripper structure, thus securing the gripper structure to the object. Since the moving block 131 and the screw part 134 are threadedly connected, the position of the moving block 131 can be locked when the screw part 134 is not rotating. That is, the opening size between the movable clamping member 12 and the fixed clamping member 11 can be locked, thereby ensuring that the gripper structure is firmly clamped on the corresponding object. The gripper structure is not easy to tilt or fall off, making it safer and more reliable to use.

[0103] Example 3

[0104] This embodiment is an example of a portable fan, such as... Figure 13As shown, the portable fan in this embodiment includes a fan body 100 and a gripper structure as described in Embodiment 1 or Embodiment 2. The gripper structure is installed at the bottom of the fan body 100 or other positions where it can be assembled. As a preferred technical solution, the bottom of the fan body 100 is fixedly connected to the fixing clamp 11.

[0105] The gripper structure and the fan body 100 can be configured to be either non-detachable or detachable. If the gripper structure is detachably connected to the fan body 100, the gripper structure can achieve this detachable connection through one or more of the following methods: snap-fit, plug-in, threaded connection, screw connection, magnetic attraction, etc. The above-mentioned detachable connection methods are merely examples and are not intended to limit the scope of this utility model.

[0106] The fan body 100 can be clamped to a desktop or rod-shaped object using a gripper structure, such as a bed rail or stroller rail. Figure 13 This illustration shows the fan body 100 being clamped onto the rod-shaped object 101 in this embodiment. The construction of the fan body 100 in this embodiment is not a limiting specification; other fan bodies that can be assembled with the gripper structure are also acceptable.

[0107] When the clamping structure of this utility model is assembled with the fan body 100, compared with the traditional torsion spring press-type clamping fan and the portable fan with octopus silicone foot structure, the clamping structure in this embodiment can firmly fix the fan body to the table or rod-shaped object. The clamping structure is not easily damaged and the clamping is firm, making the fan body less likely to tilt or fall off. It is more suitable for use as a stroller fan and is safe and reliable.

[0108] It should be noted that while the preferred embodiments of this utility model are provided in the specification and accompanying drawings, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are not intended to impose additional limitations on the content of this utility model; their purpose is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Furthermore, the above-described technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this specification.
