Description

Technical Field

[0001] This utility model relates to the field of fixed bracket technology, and in particular to a clamp and an air outlet clamp. Background Technology

[0002] To facilitate mobile phone use for navigation, music playback, and streaming in the car, most people place their phones in phone holders and secure them in place. To ensure a proper fit in the car, most existing phone holders are fixed to the car's air conditioning vents using vent clips.

[0003] However, the clamps currently used in the market have poor compatibility, requiring the clamps to be replaced along with the vent clips, resulting in high costs. Furthermore, the clamping effect of existing practical clamps is unreliable; bumps during vehicle operation can easily loosen the connection between the clamp and the vent, causing the vent clip and clamp to easily fall off.

[0004] Therefore, this application proposes a technical solution to solve the above problems. Utility Model Content

[0005] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a clamp that is applicable to various air outlet clamps, improving the versatility of the clamp. Furthermore, the clamp of this application provides a reliable connection between the clamp and the air outlet, and the connection method is simple to operate. This application also provides an air outlet clamp using this clamp, which offers stable and reliable clamping, simple operation, and strong practicality.

[0006] In a first aspect, a chuck according to an embodiment of the present utility model includes:

[0007] The latch mechanism includes a latch and a telescopic component, the telescopic component being used to drive the latch to extend or retract and to rotate the latch to unfold or retract.

[0008] The telescopic assembly includes a first rod and a second rod arranged side by side. The first rod is rotatably mounted with a hook. The second rod is provided with a limiting structure for limiting the swing of the hook. The limiting structure includes a limiting opening and a limiting part located in the limiting opening. The limiting opening is provided in one of the second rod and the hook, and the limiting part is provided in the other of the second rod and the hook.

[0009] When one of the first and second rods drives the other to extend or retract in the same direction, the limiting opening abuts against the limiting part in the direction of the hook's rotation, so that the hook can rotate to unfold or retract.

[0010] A chuck according to an embodiment of the present utility model has at least the following beneficial effects:

[0011] When the first member of the clamp is in its initial position, i.e., in its non-extended state, the hook on the first member is retracted. When the first member begins to move in the first direction, it can push the hook to rotate and unfold. However, due to the restraining structure on the second member constraining the hook's swing, the hook on the first member fails to rotate and unfold during the movement. During the extension of the first member, the hook exerts a pushing force on the second member, allowing it to extend synchronously with the second member as the first member continues to extend. As the second member extends synchronously, the restraining structure on the second member always maintains its constraint on the hook's swing. When the first member is fully extended, i.e., at its maximum stroke in the extended state, the second member also stops extending synchronously. When the first rod moves in the second direction, the first direction is opposite to the second direction. That is, when the first rod is retracted, at the instant it begins to move and retract, it exerts a force in the second direction on the hook. At this time, the first rod can pull the hook to rotate and unfold. As the first rod continues to move, the unfolding angle of the hook gradually increases. However, due to the constraint of the limiting structure, the range of the hook's rotational unfolding angle is limited. When the hook rotates and unfolds to its maximum angle, it exerts a thrust in the second direction on the limiting structure. That is, the hook exerts a thrust on the second rod, so that during the continuous retraction of the first rod, the first rod can pull the second rod to retract synchronously. When the hook is in the unfolded state, the clamp can be fixed to the blades of the air outlet using the hook. By utilizing the cooperation between the hook and the main body of the clamp, the air outlet can be stably fixed to the air outlet.

[0012] In practical applications, removing the clamp from the air outlet is very simple. Users only need to extend the first rod, which then pushes the clamp to rotate and retract, allowing the clamp to be removed. To attach the clamp to the air outlet, the user simply returns the hook to its inverted position, inserts the telescopic component into the air outlet, and then retracts the first rod to extend the hook and engage it with the air outlet. The clamp of this application has a compact overall structure. Utilizing the synchronously extendable first and second rods as the main support components, it improves the clamp's load-bearing capacity, making it less prone to falling off. Furthermore, by adjusting the hook's extension angle, the clamp can be adapted to air outlet blades of varying thicknesses, improving its clamping stability and versatility.

[0013] According to an embodiment of the present invention, a clamp, when one of the first rod and the second rod drives the other to extend and retract in the same direction, a limiting opening abuts against a limiting part in the rotation direction of the hook, so that the hook can rotate to unfold or retract, including:

[0014] When one of the first and second rods extends, in the rotation direction of the hook, one side of the limiting opening abuts against the limiting part to keep the hook in the retracted state. The limiting opening cooperates with the limiting part to drive the other of the first and second rods to extend.

[0015] And / or,

[0016] When one of the first and second rods retracts, the other side of the limiting opening abuts against the limiting part, allowing the hook to rotate and unfold. When the hook unfolds to its maximum angle, the limiting opening cooperates with the limiting part, causing the other of the first and second rods to retract.

[0017] According to an embodiment of the present invention, a clamp has a limiting opening disposed on a second rod, and the limiting part includes a first abutting surface and a second abutting surface located on both sides of the rotation direction of the hook.

[0018] According to an embodiment of the present invention, a clamp has a second rod with a mounting groove, and a flipping shaft is provided in the mounting groove. The flipping shaft cooperates with the inner wall of the mounting groove to form a limiting opening.

[0019] According to an embodiment of the present utility model, a clamp includes a mounting part and a hook part connected to the mounting part. The mounting part is connected to a first rod, and a first abutting surface and a second abutting surface are located at the connection between the mounting part and the hook part.

[0020] According to an embodiment of the present utility model, a chuck has a protrusion at the end of the mounting groove away from the flipping shaft. The protrusion is located on the same side as the second abutting surface and abuts against the second abutting surface.

[0021] According to an embodiment of the present invention, the telescopic assembly further includes a guide structure, which includes a guide groove and a guide strip that is matched and connected to the guide groove. Both the guide groove and the guide strip extend along the moving direction of the telescopic assembly. The guide groove is located in one of the first rod and the mounting groove, and the guide strip is located in the other of the first rod and the mounting groove.

[0022] According to an embodiment of the present invention, a chuck has a guide groove located inside the mounting groove, a guide strip located on a first rod, and the guide strip and the guide groove being matched and inserted into each other.

[0023] According to an embodiment of the present utility model, the chuck further includes a rotation adjustment mechanism, which includes a hollow rotating component. The end of a first rod away from the hook is movably connected to the rotating component. Rotating the rotating component clockwise or counterclockwise can cause the first rod to perform reciprocating linear motion.

[0024] Secondly, according to an embodiment of the present invention, an air outlet clamp utilizes the aforementioned clamp.

[0025] An air outlet clip according to an embodiment of the present utility model has at least the following beneficial effects:

[0026] When using the air outlet clamp with the clamp of this application, it is very simple for the user to remove the air outlet clamp from the air outlet. Simply extend the first rod, and the first rod will push the clamp to rotate and retract, allowing the clamp to be removed. To fix the clamp to the air outlet, the user simply returns the hook to its closed state, inserts the telescopic component into the air outlet, and then retracts the first rod to extend the hook and engage it with the air outlet. The clamp of this application has a compact overall structure. Utilizing the synchronously extendable first and second rods as the main support components of the clamp, it can improve the load-bearing capacity of the clamp, making it less likely to fall off. Furthermore, by adjusting the extension angle of the hook, the clamp can be adapted to air outlet blades of different thicknesses, improving the clamping stability and versatility of the air outlet clamp.

If the terms "first" and "second" are used, they are merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or the order of the indicated technical features.

[0051] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0052] Reference Figures 1 to 6 This utility model embodiment provides a clamp.

[0053] Reference Figure 1 The chuck mainly consists of an installation mechanism 3, a rotary adjustment mechanism 2 mounted on the installation mechanism 3, and a hook mechanism 1, wherein the hook mechanism 1 is movably connected to the rotary adjustment mechanism 2.

[0054] Specifically, the hook mechanism 1 includes a hook 100 and a telescopic component 200. The telescopic component 200 is movably connected to the rotary adjustment mechanism 2. When the rotary adjustment mechanism 2 rotates clockwise or counterclockwise, the telescopic component 200 can extend or retract. At the same time, when the telescopic component 200 extends or retracts, it can drive the hook 100 to rotate and unfold or retract.

[0055] It is understandable that the rotary adjustment structure is the driving component for the movement of the telescopic component 200. The user drives the telescopic component 200 to move by rotating the rotary adjustment mechanism 2, and the movement of the telescopic component 200 drives the hook 100 to rotate.

[0056] According to some embodiments of this application, the telescopic assembly 200 includes a first rod 210 and a second rod 220 arranged side by side. The first rod 210 is rotatably mounted with a hook 100. The second rod 220 is provided with a limiting structure for limiting the swing of the hook 100. The limiting structure includes a limiting opening and a limiting part located in the limiting opening. The limiting opening is provided in one of the second rod 220 and the hook 100, and the limiting part is provided in the other of the second rod 220 and the hook 100.

[0057] When one of the first rod 210 and the second rod 220 drives the other to extend and retract in the same direction, the limiting opening abuts against the limiting part in the rotation direction of the hook 100, so that the hook 100 rotates to unfold or retract.

[0058] Specifically, in the embodiments of this application, the first rod 210 is the driving rod, and the second rod 220 is the driven rod. It can be understood that when the first rod 210 moves telescopically, it drives the second rod 220 to move telescopically synchronously through the hook 100.

[0059] In specific embodiments of this application, such as Figure 3 As shown, the second rod 220 is provided with a mounting groove 221, and a flipping shaft 222 is provided in the mounting groove 221. The flipping shaft 222 cooperates with the inner wall of the mounting groove 221 to form a limiting opening. Further, the first rod 210 is installed in the mounting groove 221, and the first rod 210 can move along the length direction of the mounting groove 221.

[0060] The limiting part includes a first abutment surface and a second abutment surface located on both sides of the rotation direction of the hook 100. As shown in the figure, the hook 100 includes a mounting part 110 and a hook part 120 connected to the mounting part 110. The mounting part 110 is connected to the first rod 210, and the first and second abutment surfaces are located at the connection between the mounting part 110 and the hook part 120. That is, when the hook 100 rotates, the first abutment surface abuts against the flip shaft 222, while the second abutment surface abuts against the inner wall of the mounting groove 221. A limiting space is formed between the flip shaft 222 and the mounting groove 221 to constrain the rotation angle of the hook 100.

[0061] As a further improvement to the present application, a protrusion 223 is provided at the end of the mounting groove 221 away from the flip shaft 222. The protrusion 223 is located on the same side as the second abutment surface and abuts against the second abutment surface. It can be understood that, on the one hand, the user can adjust the maximum unfolding angle of the hook 100 by the specific amount of intrusion of the protrusion 223 into the mounting groove 221. On the other hand, it can also improve the abutment reliability of the hook 100, ensuring that the hook 100 is not easy to slip off when unfolded at the maximum angle, avoiding the clamping failure of the chuck and its falling off, thus helping to ensure the clamping reliability of the chuck.

[0062] According to some embodiments of this application, the telescopic assembly 200 is further provided with a guide structure, which includes a guide groove 224 and a guide strip 211 that is matched and connected to the guide groove 224. Both the guide groove 224 and the guide strip 211 extend along the moving direction of the telescopic assembly 200. The guide groove 224 is located in one of the first rod 210 and the mounting groove 221, and the guide strip 211 is located in the other of the first rod 210 and the mounting groove 221.

[0063] Specifically, in a specific embodiment of this application, a guide strip 211 is disposed on the outer wall of the first rod 210, and a guide groove 224 is disposed on the second rod 220, with the guide strip 211 matching the guide groove 224. During the installation of the first rod 210 and the second rod 220, and during the relative movement of the first rod 210 and the second rod 220 when the first rod 210 pulls the hook 100, the guide structure provides guidance.

[0064] Furthermore, as a preferred embodiment of this application, the mounting groove 221 is provided with first through holes 225 on both sides near the limiting opening. The axis of the first through hole 225 is coaxial with the axis of the connecting shaft between the hook 100 and the first rod 210. When it is necessary to disassemble or assemble the hook 100, simply insert a disassembly tool into the first through hole 225 and push the connecting shaft out through the first through hole 225 to separate the hook 100 from the first rod 210.

[0065] According to some embodiments of this application, a first connector 212 is fixedly connected to the end of the first rod 210 away from the hook 100. Specifically, the first connector 212 is provided with a connecting hole 2121, and the end of the second rod 220 is provided with a plug-in portion 226, which is correspondingly matched and connected to the connecting hole 2121. Further, a baffle 213 is provided at the end of the first rod 210, and the plug-in portion 226 of the second rod 220 passes through the plug-in hole and abuts against the baffle 213.

[0066] Specifically, such as Figure 3 and Figure 4 As shown, the insertion part 226 is provided with a snap-fit ​​block 2261, which is disposed in the gap between the baffle 213 and the first connecting member 212. The snap-fit ​​block 2261 is used to strengthen the connection stability between the first rod 210 and the second rod 220. Furthermore, to ensure that the insertion part 226 can pass smoothly through the connection hole 2121, the bottom of the mounting groove 221 is provided with an open slot, so that when the insertion part 226 passes through the connection hole 2121, the main body of the second rod 220 can undergo slight deformation, so that the snap-fit ​​block 2261 can pass through the connection hole 2121. After passing through the connection hole 2121, after the deformation of the second rod 220 returns to normal, the snap-fit ​​block 2261 can be inserted into the gap between the baffle 213 and the first connecting member 212.

[0067] It is important to note that, for example Figure 5 As shown, a gap L is left between the first connecting member 212 and the second rod 220 to ensure that the first rod 210 can move relative to the second rod 220 so that the first rod 210 can pull or push the hook 100 to rotate.

[0068] According to some embodiments of this application, the rotary adjustment mechanism 2 includes a hollow rotary member 300. The end of the first rod 210 away from the hook 100 is movably connected to the rotary member 300. Rotating the rotary member 300 clockwise or counterclockwise can cause the first rod 210 to perform reciprocating linear motion.

[0069] Specifically, such as Figure 6 As shown, the inner cavity of the rotating member 300 is provided with an internal thread, and correspondingly, the outer wall of the first connecting member 212 is provided with a matching external thread. The first connecting member 212 is threadedly connected to the rotating member 300 so that rotating the rotating member 300 clockwise or counterclockwise can make the first rod 210 reciprocate linearly.

[0070] Furthermore, as a preferred embodiment of this application, the clamp further includes a first damping mechanism. Specifically, as shown in the example... Figure 3 and Figure 6 As shown, the first damping mechanism includes a third rod 400 disposed in the inner cavity of the rotating member 300 and a damping spring 214 disposed on the first rod 210. The third rod 400 is provided with a slot 410, and multiple slots 410 are arranged along the length direction of the third rod 400. The end of the damping spring 214 can be engaged in the slot 410.

[0071] When the user rotates the rotating component 300 to extend or retract the first rod 210, the first damping component can slide out of the previous slot 410 and then into the next slot 410 when it is moved. The sticking sensation generated by the first damping component and the slot 410 during multiple separations and engagements can provide the user with obvious tactile feedback, allowing the user to clearly perceive the rotation state of the rotating component 300.

[0072] Furthermore, the first damping mechanism provides a certain resistance and buffer during the rotation of the rotating component 300, avoiding rapid or sudden movements, thus providing a smoother and more comfortable operating experience. This allows the user to more accurately control the rotation speed and force of the rotating component 300, better adjust the extension of the first rod 210 and the second rod 220, and also prevent excessive rotation that could cause the latch 100 to fail.

[0073] Furthermore, the end of the first rod 210 is provided with an open mounting cavity 215, and the two ends of the damping spring 214 are inserted into the mounting cavity 215 through the opening, which is simple in structure and easy to assemble and disassemble.

[0074] According to some embodiments of this application, the rotating component 300 is provided with a rotating shell 310 on its outer side. Specifically, a handle 311 is fixedly connected to the outside of the rotating shell 310, and two handles 311 are arranged opposite to each other to facilitate the user to rotate the rotating component 300.

[0075] According to some embodiments of this application, such as Figure 7 As shown, the mounting mechanism 3 includes a base 500 and a decorative cover 510 sleeved on the outside of the base 500. Specifically, one side of the base 500 is recessed to form a groove for mounting the rotating member 300. At the same time, a second through hole is provided at the bottom of the groove. The end of the first rod 210 away from the hook 100 passes through the second through hole from the end near the rotating member 300 and is then mounted on the base 500.

[0076] Preferably, an extension plate 520 is provided on the side of the base 500 facing away from the rotating component 300. As shown in the figure, the extension plate 520 can be attached to the blades of the air outlet. The extension plate 520 and the hook 100 together form a clamping cavity for clamping the air outlet blades, so as to further improve the clamping stability of the clamp. Even in the event of vibration, it can be clamped stably and is not easy to loosen or fall off.

[0077] like Figures 7 to 10 As shown, the specific working principle of the chuck in this application is as follows:

[0078] For ease of understanding, this application defines the direction in which the telescopic component 200 extends as the first direction and the direction in which the telescopic component 200 retracts as the second direction.

[0079] When the telescopic component 200 is in its original position, i.e., as Figure 7 As shown, when the telescopic component 200 is in the non-extended state, the hook 100 is in the retracted state.

[0080] When the user needs to fix the clamp to the blades of the air outlet, the user rotates the adjustment mechanism 2 clockwise, and the rotating part 300 causes the first rod 210 to begin moving in the first direction. When the first rod 210 begins to move in the first direction, the first rod 210 can push the hook 100 to rotate and unfold. However, because the limiting structure on the second rod 220 restrains the swing of the hook 100, the hook 100 on the first rod 210 fails to rotate and unfold during the movement. But during the extension of the first rod 210, the hook 100 has a pushing effect on the second rod 220, so that when the first rod 210 continues to extend, the first rod 210 can drive the second rod 220 to extend synchronously. When the second rod 220 extends synchronously, the limiting structure on the second rod 220 can always maintain restraint on the swing of the hook 100. When the first rod 210 is fully extended, that is, as Figure 8 As shown, when the first link 210 is at its maximum extension, the second link 220 is also synchronously stopped extending.

[0081] When the user rotates the adjustment mechanism 2 counterclockwise, the first lever 210 begins to move in the second direction. When the first lever 210 moves in the second direction, that is, when the first lever 210 is retracted, at the instant the first lever 210 begins to move and retract, it generates a force in the second direction on the latch 100, such as... Figure 9 As shown, the first rod 210 can pull the hook 100 to rotate and unfold. As the first rod 210 continues to move, the unfolding angle of the hook 100 gradually increases. However, due to the constraint of the limiting structure, the range of the unfolding angle of the hook 100 is limited. When the hook 100 is fully unfolded, it generates a thrust in the second direction on the limiting structure, that is, it generates a thrust on the second rod 220, so that during the continuous retraction of the first rod 210, the first rod 210 can pull the second rod 220 to retract synchronously. When the hook 100 is in the unfolded state, the clamp can be hooked and fixed to the blades of the air outlet using the hook 100. By using the cooperation between the hook 100 and the main body of the clamp, the air outlet can be stably fixed to the air outlet.

[0082] When the user needs to remove the clamp from the air outlet blades, simply rotate the adjustment mechanism 2 clockwise again. This will cause the hook 100 to retract under the pushing force of the first rod 210, allowing the user to remove the clamp. Figure 10 As shown, the user can fully retract the telescopic component 200 by rotating the clamp that has been removed from the air outlet blades counterclockwise through its rotation adjustment mechanism 2.

[0083] Of course, in actual use, the user does not need to fully extend the telescopic component 200 to its maximum stroke. The user only needs to adjust the telescopic component 200 to a suitable length by rotating the adjustment mechanism 2 according to the actual situation.

[0084] This application also provides an air outlet clamp (not shown) using the clamp of this application.

[0085] The air outlet clamp (not shown) includes a clamp head and a clamping assembly (not shown). The clamp head is provided with a connecting assembly, and the clamping assembly (not shown) is mounted on the clamp head through the connecting assembly.

[0086] Specifically, such as Figure 2 As shown, the connecting assembly includes a second connecting member 420 and a third connecting member 430 disposed on the third rod 400. The second connecting member 420 has a universal joint 421 at its end, and the third connecting member 430 is rotatably connected to the universal joint 421. Furthermore, the third connecting member 430 has an internal thread in its inner cavity, and the clamping assembly can be fixed to the clamp by providing a matching external thread.

[0087] When using the air outlet clamp (not shown) with the clamp of this application, it is very simple for the user to remove the air outlet clamp (not shown) from the air outlet. Simply extend the first rod 210, and after the first rod 210 pushes the clamp to rotate and retract, the clamp can be removed. To fix the clamp to the air outlet, return the hook 100 to its unextended state, insert the telescopic component 200 into the air outlet, and then retract the first rod 210 to extend the hook 100 and hook it onto the air outlet. The clamp of this application has a compact overall structure. Utilizing the synchronously extendable first rod 210 and second rod 220 as the main support components of the clamp, the load-bearing capacity of the clamp can be improved, making the clamp less likely to fall off. Furthermore, by adjusting the extension angle of the hook 100, the clamp can be adapted to air outlet blades of different thicknesses, improving the clamping stability and adaptability of the air outlet clamp (not shown).
