Description

Technical Field

[0001] This application relates to the field of photographic equipment, and in particular to a clamping device and photographic apparatus. Background Technology

[0002] Outdoor photography, especially "travel photography" which is closely integrated with travel, has developed rapidly in recent years and has become an important way to connect travel experiences, cultural dissemination and personal memories.

[0003] When it is necessary to fix shooting equipment such as cameras in outdoor environments, a clamping device is usually required. One side of the clamping device is connected to the shooting equipment, and the other side is clamped to the position where the shooting equipment needs to be fixed, such as a tree trunk or railing.

[0004] Existing clamping devices (such as crab claw clamps) typically have two clamps hinged to a pivot, which results in a clamping distance that is too small to clamp onto larger supports (such as the side of a wall, trees, etc.). Utility Model Content

[0005] The main objective of this application is to provide a clamping device and photographic equipment, which aims to enable the clamping device to hold a support of a large volume.

[0006] To achieve the above objectives, this application proposes a clamping device for use in photographic equipment, the clamping device comprising:

[0007] The base is elongated.

[0008] Two sets of clamping mechanisms are arranged at intervals along the length direction of the base and are slidably connected to the base. Each set of clamping mechanisms includes:

[0009] A connecting seat, one end of which is slidably connected to the base;

[0010] A clamp assembly is movably mounted on one side of the connector, and the two clamp assemblies are arranged opposite to each other;

[0011] An adjustment component, connected to one of the clamping assemblies, is used to drive the clamping assembly to move toward or away from the other clamping assembly along the length direction of the base.

[0012] In some embodiments, the clamping mechanism is detachably connected to the base.

[0013] In some embodiments, the adjustment assembly includes a handle and a linkage, the linkage being movably disposed through the connecting seat, one end of the linkage being connected to the clamp assembly, and the other end being connected to the handle.

[0014] In some embodiments, the connector is provided with a positioning pin, and the base is provided with a plurality of positioning holes. One end of the positioning pin is inserted into one of the positioning holes to fix the connector to the base.

[0015] In some embodiments, the connector further includes an actuating element and an elastic element, the actuating element being connected to the positioning pin and partially exposed in the connector, and the elastic element being connected between the other end of the positioning pin and the connector.

[0016] In some embodiments, the connecting seat has sliding portions on opposite sides, and the base has protrusions on opposite sides extending along the length direction of the base. One of the protrusions passes through one of the sliding portions, so that the connecting seat can be slidably connected to the base.

[0017] In some embodiments, limiting members protrude from both ends of the base.

[0018] In some embodiments, the chuck assembly includes a first clamping block, a second clamping block, and a third clamping block, wherein the second clamping block is mounted on the first clamping block, and two third clamping blocks are mounted on the second clamping block, and each third clamping block is slidably connected to the second clamping block along the circumferential direction of the third clamping block.

[0019] In some embodiments, the second clamping block is slidably connected to the first clamping block along the circumferential direction of the second clamping block.

[0020] In some embodiments, the first clamping block is rotatably connected to the connecting seat.

[0021] This application further proposes a photographic device, including a clamping device and a photographic device as described above, wherein the base of the clamping device faces away from the surface of the clamping mechanism for detachable connection with the photographic device.

[0022] The clamping device proposed in this application includes an elongated base and clamping mechanisms detachably connected to the base. The clamping head assemblies of the two clamping mechanisms abut against the opposite sides of a large-volume support. An adjusting component drives one clamping head assembly to move towards the other clamping head assembly to clamp the support. Compared to existing structures where two clamping heads are hinged to a single pivot, the clamping device in this application, through a sliding connection between the two clamping mechanisms and the base, allows for flexible adjustment of the distance between the two clamping mechanisms. This enables the clamping device to clamp supports with a wider range of sizes, enriching its application scenarios. Attached Figure Description

[0031] Outdoor photography, especially "travel photography" which is closely integrated with travel, has developed rapidly in recent years and has become an important way to connect travel experiences, cultural dissemination and personal memories.

[0032] When it is necessary to fix shooting equipment such as cameras in outdoor environments, a clamping device is usually required. One side of the clamping device is connected to the shooting equipment, and the other side is clamped to the position where the shooting equipment needs to be fixed, such as a tree trunk or railing.

[0033] Existing clamping devices (such as crab claw clamps) typically have two clamps hinged to a pivot, which results in a clamping distance that is too small to clamp onto larger supports (such as the side of a wall, trees, etc.).

[0034] This application discloses a clamping device 100, with reference to... Figures 1 to 4 , Figure 1 This is a schematic diagram of the structure of one embodiment of the clamping device 100 of this application. Figure 2 This is a schematic diagram of the structure of one embodiment of the chuck assembly 122 in the clamping device 100 of this application. Figure 3 This is a schematic diagram of another embodiment of the chuck assembly 122 in the clamping device 100 of this application. Figure 4 for Figure 3 A cross-sectional view at point AA. In some embodiments, the clamping device 100 includes a base 110 and two sets of clamping mechanisms 120. The base 110 is elongated. Each set of clamping mechanisms 120 includes a connecting seat 121, a chuck assembly 122, and an adjusting assembly 123. One end of the connecting seat 121 is slidably connected to the base 110. The chuck assembly 122 is movably mounted on one side of the connecting seat 121, and the two chuck assemblies 122 are arranged opposite to each other. The adjusting assembly 123 is connected to one of the chuck assemblies 122 and is used to drive the chuck assembly 122 to move toward or away from the other chuck assembly 122 along the length direction of the base 110.

[0035] In this embodiment, the base 110 serves as the main component of the clamping device 100, connecting the shooting equipment and the clamping mechanism 120, and providing a stable and robust support foundation for both, thereby improving shooting stability. The base 110 is made of lightweight metal, such as aluminum alloy or titanium alloy, offering advantages such as durability, good corrosion resistance, and low density, making it easy for photographers to handle and carry. The base 110 is elongated, meaning its length is significantly greater than its width. This longer length allows the clamping device 100 to be clamped onto wider supports, such as tree trunks or walls, increasing its clamping range and expanding its application scenarios. Furthermore, the sliding connection between the two clamping mechanisms 120 and the elongated base 110 ensures natural alignment of the two clamping mechanisms, eliminating the need for additional alignment calibration and saving installation time. The length of the base 110 should be selected according to the required clamping position, and no further limitation is made here.

[0036] The clamping mechanism 120 is a component of the clamping device 100 that provides clamping functionality, serving to fix the clamping device 100 to a support (such as the side of a wall, a tree, etc.). The clamping mechanism 120 is made entirely of metal, such as stainless steel or aluminum alloy, and has a certain degree of rigidity, allowing it to be clamped to locations such as tree trunks or the side of walls. The two clamping mechanisms 120 are slidably connected to the base 110, and the distance between the two clamping mechanisms 120 can be adjusted by sliding the connection to accommodate supports of different widths.

[0037] The clamping mechanism 120 includes a connecting seat 121, a clamping head assembly 122, and an adjusting assembly 123. The connecting seat 121 is the main body of the clamping mechanism 120, and one end of the connecting seat 121 is detachably connected to the base 110, realizing a detachable connection between the clamping mechanism 120 and the base 110. The clamping head assembly 122 is installed on one side of the connecting seat 121. The clamping head assemblies 122 of the two clamping mechanisms 120 are arranged opposite to each other. The clamping distance is determined by the detachable connection between the connecting seat 121 and the base 110, thereby achieving the effect of clamping the support with the two clamping head assemblies 122. The clamping head assembly 122 is a component that directly contacts the support. The surface of the clamping head assembly 122 facing the support has several grooves to increase the friction between the clamping head assembly 122 and the support, thereby making the clamping between the clamping head assembly 122 and the support tighter. Adjustment component 123 is a component for further locking clamp assembly 122. Adjustment component 123 drives at least one clamp assembly 122 to move the clamp assembly 122 toward the other clamp assembly 122 opposite to it, so as to clamp the support by the two clamp assemblies 122.

[0038] It is understood that, in other embodiments, the two clamping assemblies 122 of the two clamping mechanisms 120 may be arranged back to back, so that the two clamping assemblies 122 can abut against the inner walls of the tubular object or the inner walls of the box, and the clamping device 100 can be installed on the inner wall of the tubular object or the inner wall of the box, thus enriching the application scenarios of the clamping device 100 and improving its flexibility of use.

[0039] When using the clamping device 100 of this application, two clamping mechanisms 120 are first slidably mounted on the base 110 at intervals. The clamping distance of the support is initially determined by the distance between the two clamping mechanisms 120. Then, the adjustment component 123 drives at least one clamping head assembly 122 to move toward the other clamping head assembly 122, so that the two clamping head assemblies 122 abut against the opposite sides of the support and clamp it, thereby achieving the effect of installing the clamping device 100 on the support.

[0040] The clamping device 100 proposed in this application includes an elongated base 110 and clamping mechanisms 120 detachably connected to the base 110. The clamping head assemblies 122 of the two clamping mechanisms 120 abut against the opposite sides of a large-volume support. Then, an adjusting component 123 drives one of the clamping head assemblies 122 to move towards the other clamping head assemblies 122 to clamp the support. Compared with the existing structure where the two clamps are hinged to a pivot, the clamping device 100 in this application, through the sliding connection between the two sets of clamping mechanisms 120 and the base 110, can flexibly adjust the distance between the two sets of clamping mechanisms 120, thereby enabling the clamping device 100 to clamp supports with a wide range of sizes and enriching the application scenarios of the clamping device 100.

[0041] In some embodiments, the clamping mechanism 120 is detachably connected to the base 110.

[0042] In this embodiment, the clamping mechanism 120 is detachably connected to the base 110. When transporting or changing the installation position, the two clamping mechanisms 120 can be removed from the base 110, which facilitates transportation. The specific connection method between the clamping mechanism 120 and the base 110 can be a sliding groove connection or a sliding snap connection, etc., and is not further limited here.

[0043] In some embodiments, refer to Figures 2 to 4 The adjustment component 123 includes a handle 1231 and a connecting rod 1232. The connecting rod 1232 is movably inserted through the connecting seat 121. One end of the connecting rod 1232 is connected to the clamp assembly 122, and the other end is connected to the handle 1231.

[0044] In this embodiment, the connecting rod 1232 is a component that movably passes through the connecting seat 121. One end of the connecting rod 1232 is connected to the clamp assembly 122. By moving the connecting rod 1232 relative to the connecting seat 121, the clamp assembly 122 is driven to move together relative to the connecting seat 121, so that the clamp assembly 122 moves toward or away from the other clamp assembly 122, ultimately achieving the effect of clamping or releasing the support. The movable connection between the connecting rod 1232 and the connecting seat 121 can be a threaded connection or a trapezoidal lead screw connection, etc. By rotating the connecting rod 1232, the connecting rod 1232 can rotate and move relative to the connecting seat 121, thereby driving the movement of the clamp assembly 122 and achieving the effect of clamping the support. The handle 1231 is connected to the end of the connecting rod 1232 away from the chuck assembly 122, which facilitates driving the connecting rod 1232. Compared with the user directly rotating the connecting rod 1232, the advantage of rotating the connecting rod 1232 by the handle 1231 is that it saves manpower and can extend the lever, so that the two chuck assemblies 122 can clamp more tightly and increase the clamping force between the clamping device 100 and the support.

[0045] In some embodiments, refer to Figure 1 , Figure 3 and Figure 4 The connecting seat 121 is provided with a positioning pin 1211, and the base 110 is provided with multiple positioning holes 111. One end of the positioning pin 1211 is inserted into a positioning hole 111 to fix the connecting seat 121 to the base 110.

[0046] In this embodiment, the positioning pin 1211 is a positioning component movably mounted on the connecting seat 121. Correspondingly, the base 110 is provided with a positioning hole 111, which is a blind hole on the surface of the base 110. Through the insertion connection between the positioning pin 1211 and the positioning hole 111, the connecting seat 121 and the base 110 are fixed, thereby achieving the effect of fixing the clamping mechanism 120. There are multiple positioning holes 111, which are evenly distributed along the length direction of the base 110. Through the insertion and engagement between the positioning pin 1211 and each positioning hole 111, the connection between the connecting seat 121 and the base 110 at different positions can be achieved, thereby achieving the effect of adjusting the distance between the two clamping mechanisms 120, adjusting the clamping distance of the clamping device 100, enriching the application scenarios of the clamping device 100, and improving the flexibility of the clamping device 100.

[0047] In some embodiments, refer to Figure 3 and Figure 4 The connecting seat 121 also includes an actuating element 1212 and an elastic element 1213. The actuating element 1212 is connected to the positioning pin 1211 and is partially exposed in the connecting seat 121. The elastic element 1213 is connected between the other end of the positioning pin 1211 and the connecting seat 121.

[0048] In this embodiment, a groove is formed on the bottom surface of the connecting seat 121 facing the base 110. The positioning pin 1211 is movably disposed in the groove and can be partially exposed at the groove opening to be inserted into the positioning hole 111, thereby achieving the positioning effect between the connecting seat 121 and the base 110. The actuating member 1212 is a component that drives the positioning pin 1211, facilitating the movement of the positioning pin 1211. An elongated hole is formed on the side wall of the groove. One end of the actuating member 1212 passes through the elongated hole, which extends vertically, while the other end is exposed outside the positioning seat. When the user drives the other end of the actuating member 1212, the actuating member 1212 can move along the extension direction of the elongated hole, thereby driving the positioning pin 1211 to move vertically, realizing the insertion and unlocking of the positioning pin 1211 and the positioning hole 111. The other end of the actuating member 1212 is provided with a grip part for easy lifting, thereby improving the user experience. The elastic element 1213 is a component that deforms (elongates, shortens, bends, twists, etc.) when subjected to external force, and immediately returns to its original shape and size after the external force is removed. The elastic element 1213 is connected between the other end of the positioning pin 1211 and the connecting seat 121, specifically between the other end of the positioning pin 1211 and the bottom of the groove. When the positioning pin 1211 is inserted into the positioning hole 111, the elastic element 1213 is initially in a stress-free state. When the actuating element 1212 moves the positioning pin 1211 upward, the elastic element 1213 is compressed. At this time, the movable clamping mechanism 120 aligns the positioning pin 1211 with another positioning hole 111. After releasing, the elastic element 1213 restores its deformation, pushing the positioning pin 1211 into the positioning hole 111, thus fixing the connecting seat 121 and the base 110. In a preferred embodiment, when the positioning pin 1211 is inserted into the positioning hole 111, the elastic member 1213 can be in a compressed state. The elastic member 1213 can push the positioning pin 1211 to abut against the positioning hole 111, thereby increasing the connection strength between the positioning pin 1211 and the positioning hole 111, and thus improving the connection stability between the connecting seat 121 and the base 110.

[0049] In some embodiments, refer to Figure 1 and Figure 3 The connecting seat 121 has sliding portions 1214 on opposite sides, and the base 110 has protrusions 112 extending along the length of the base 110 on opposite sides. A protrusion 112 passes through a sliding portion 1214 so that the connecting seat 121 can be slidably connected to the base 110.

[0050] In this embodiment, the sliding part 1214 is a component that can slide along the base 110. The base 110 has protrusions 112 on opposite sides, and the protrusions 112 extend along the length of the base 110. The sliding part 1214 has a U-shaped structure, with one protrusion 112 passing through it, so that the sliding part 1214 can slide along the extension direction of the protrusion 112, thereby allowing the connecting seat 121 to slide relative to the base 110. The cooperation between the U-shaped sliding part 1214 and the protrusion 112 can realize the sliding connection between the sliding part 1214 and the protrusion 112, and can also play a limiting role in the vertical direction to prevent the sliding part 1214 from detaching from the base 110, thereby improving the connection strength between the connecting seat 121 and the base 110.

[0051] In some embodiments, refer to Figure 1 The base 110 has limiting members 113 protruding at both ends.

[0052] In this embodiment, the limiting member 113 is a limiting component protruding from both ends of the base 110, which prevents the connecting seat 121 from sliding off the base 110. The limiting member 113 and the base 110 can be integrally formed or welded together, and are disposed on the surface of the base 110 facing the clamping mechanism 120. It is understood that, in a preferred embodiment, at least one limiting member 113 can be detachably connected to the base 110, specifically by a threaded connection or a pin-hole connection. When it is necessary to move or store the clamping device 100, the limiting member 113 can be removed from the base 110 first, and then the clamping mechanism 120 on the base 110 can be slid off, and the base 110 and the two clamping mechanisms 120 can be moved or stored separately, which saves manpower and storage space.

[0053] In some embodiments, refer to Figure 1 , Figure 2 and Figure 4 The chuck assembly 122 includes a first clamping block 1221, a second clamping block 1222, and a third clamping block 1223. The second clamping block 1222 is mounted on the first clamping block 1221, and two third clamping blocks 1223 are mounted on the second clamping block 1222. Each third clamping block 1223 is slidably connected to the second clamping block 1222 along the circumferential direction of the third clamping block 1223.

[0054] In this embodiment, the third clamping block 1223 is a component that directly abuts against the support. The third clamping block 1223 is semi-circular in shape, with its arc portion slidably connected to the second clamping block 1222, and its flat portion used to abut against the support for stable clamping. The surface of the flat portion may have several grooves to increase the friction between the third clamping block 1223 and the support. The third clamping block 1223 is slidably connected to the second clamping block 1222, and the sliding direction of the third clamping block 1223 is its own circumferential direction. When the clamping device 100 clamps the support, due to the sliding connection between the third clamping block 1223 and the second clamping block 1222, the third clamping block 1223 can change its angle with the second clamping block 1222 under the push of the reaction force of the support to fit the shape of the clamped support. The specific connection between the third clamping block 1223 and the second clamping block 1222 can be achieved by having an arc-shaped groove on one side and an arc-shaped protrusion on the other side. The arc-shaped protrusion can rotate along the arc-shaped groove, thereby enabling the third clamping block 1223 to rotate relative to the second clamping block 1222. Through the rotatable connection between the third clamping block 1223 and the second clamping block 1222, the clamping device 100 can automatically adapt to irregularly shaped supports, such as L-shaped or V-shaped supports, expanding the range of shapes that the clamping device 100 can hold and improving the flexibility of its use. It is understood that, in a preferred embodiment, each clamping assembly 122 contains at least two third clamping blocks 1223, which can accommodate supports with more irregular shapes and increase the clamping force.

[0055] In some embodiments, refer to Figure 4 The second clamping block 1222 and the first clamping block 1221 are slidably connected along the circumferential direction of the second clamping block 1222.

[0056] In this embodiment, the second clamping block 1222 is a component connecting the first clamping block 1221 and the third clamping block 1223, providing a stable connection. The second clamping block 1222 is arc-shaped, with one side of the arc edge rotatably connected to the first clamping block 1221. The specific connection between the second clamping block 1222 and the first clamping block 1221 can be achieved by having an arc-shaped groove on one side and an arc-shaped protrusion on the other side. The arc-shaped protrusion can rotate along the arc-shaped groove, thereby enabling the second clamping block 1222 to rotate relative to the first clamping block 1221. The rotation of the second clamping block 1222 relative to the first clamping block 1221 drives the third clamping block 1223 to rotate relative to the first clamping block 1221, further expanding the range of rotation angles. This allows the clamping device 100 to fit more shapes of supports, improving the flexibility of the clamping device 100.

[0057] In some embodiments, please refer again Figure 4 The first clamping block 1221 is rotatably connected to the connecting seat 121.

[0058] In this embodiment, the first clamping block 1221 serves as the base 110 of the clamping assembly 122, and is used to rotatably connect to one side of the connecting seat 121. Specifically, the rotatable connection can be achieved using a universal ball joint or a rotating shaft. This allows the first clamping block 1221 to rotate on a vertical plane perpendicular to the plane of the connecting seat 121, thereby causing the second clamping block 1222 and the third clamping block 1223 to rotate on the same vertical plane. This further expands the rotation angle range of the clamping assembly 122 of the clamping device 100, enabling the clamping device 100 to accommodate supports of more shapes and improving its usability.

[0059] In a preferred embodiment, the connecting seat 121 includes a base and a column connected together. The base is slidably connected to the base 110. One end of the column is provided with a positioning pin 1211, and the other end of the column is connected to a clamp assembly 122. The column and the base are rotatably connected. When the positioning pin 1211 is retracted, the column can rotate relative to the base to achieve the effect of saving storage space.

[0060] In a preferred embodiment, the connecting seat 121 is provided with a glass bead assembly. When the connecting seat 121 slides on the base 110, the glass bead assembly can collide with the positioning hole 111 on the base 110 and make a "ding-ding" sound, providing feedback to the user through sound. Through the cooperation between the distance between the glass bead assembly and the positioning pin 1211 and the distance between the two positioning holes 111, when the glass bead assembly makes a sound, the positioning pin 1211 is aligned with the positioning hole 111, so that the positioning pin 1211 can be inserted into the positioning hole 111, achieving the effect of not needing to observe with the eyes.

[0061] This application further proposes a photographic device, including a clamping device 100 and a photographic device as described above, wherein the base 110 of the clamping device 100 faces away from the surface of the clamping mechanism 120 for detachable connection with the photographic device.

[0062] The base 110 of the clamping device 100 has multiple Arri positioning holes 111 and multiple 1 / 4 screw holes on the surface opposite to the clamping mechanism 120, which can be used to load other photographic devices.

[0063] In use, the clamping device 100 of this application first slides two clamping mechanisms 120 onto the surface of the base 110 with positioning holes 111. The distance between the two clamping mechanisms 120 is set by inserting positioning pins 1211 and positioning holes 111. The distance should be slightly greater than the thickness of the support. The rotation angle of the first clamping block 1221 and the second clamping block 1222 is adjusted to adapt to irregularly shaped supports. Then, the support is inserted between the two clamping mechanisms 120. Then, the handle 1231 of the adjusting component 123 is rotated to drive the connecting rod 1232 and the clamping head assembly 122 to move towards the other clamping head assembly 122 to press the support. During the pressing process, the third clamping block 1223 can rotate relative to the second clamping block 1222 under the action of reaction force to fit the surface of the irregularly shaped support and improve the clamping effect. Finally, the camera device is installed through multiple Arri positioning holes 111 and multiple 1 / 4 screw holes on the back of the base 110 to achieve the effect of fixing the camera device to the irregularly shaped support.

All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
