Description

Technical Field

[0001] This utility model relates to the field of photographic equipment technology, and in particular to a telescopic component of a photographic equipment and a photographic equipment. Background Technology

[0002] In the field of photographic equipment, telescopic components play a crucial role in products such as shoulder mounts, support extension devices, and various telescopic devices. As the core component enabling connection, fixation, and telescopic adjustment of parts, the performance and structural design of the telescopic component directly affect the overall performance of the product. With its length adjustment function, the telescopic component can achieve flexible and free adjustment in a wide variety of usage scenarios, and achieve a reliable and stable locking effect, thus fully meeting the diverse support and expansion needs of photographic equipment.

[0003] However, the locking mechanism of telescopic components in related technologies generally suffers from significant drawbacks. Existing locking structures are often quite complex, containing numerous internal parts. This not only makes the actual setup process extremely cumbersome, consuming a great deal of time and effort for the user, but also occupies a large structural space within the product, resulting in a bulky overall size. This larger size not only increases the burden on users when carrying the product, but may also negatively impact ease of operation during actual use, thus reducing the user experience.

[0035] This utility model embodiment proposes a telescopic component for photographic equipment. The photographic equipment involved can be a shoulder-mounted device, a support extension device, or various telescopic devices, etc., and this embodiment does not limit this. The photographic equipment has a telescopic component, and the number of telescopic components can be one or more, depending on actual needs. The telescopic component has a telescopic function, and its length can be adjusted by extending or shortening.

[0036] Reference Figures 1 to 3The telescopic components of the photographic equipment include:

[0037] First arm body 100;

[0038] The second arm 200 is slidably disposed on the first arm 100;

[0039] The locking component 300 is disposed on one of the first arm body 100 and the second arm body 200. The other of the first arm body 100 and the second arm body 200 is provided with a plurality of tooth grooves 300C, which are arranged sequentially at intervals along the sliding direction of the second arm body 200.

[0040] The locking assembly 300 includes a rotatable locking pawl 310 and a reset member 320. The locking pawl 310 can be rotated to switch between a locked position and an unlocked position. When the locking pawl 310 is in the locked position, it inserts into the tooth groove 300C to fix the second arm 200 relative to the first arm 100. When the locking pawl 310 is in the unlocked position, it exits the tooth groove 300C to allow the second arm 200 to move and extend relative to the first arm 100. The reset member 320 acts on the locking pawl 310 to provide a force to the locking pawl 310 to reset it toward the locked position.

[0041] In this embodiment, the first arm 100 serves as the basic support part of the entire telescopic assembly, providing a carrier for the installation and connection of other components. Its material can be selected from high-strength and lightweight metal materials such as aluminum alloy, so as to ensure stable support while reducing the overall weight and making it convenient for users to carry.

[0042] The second arm 200 is slidably disposed on the first arm 100. Specifically, this sliding connection can be achieved by providing a smooth groove inside the first arm 100, and a corresponding slider on the second arm 200 that fits the groove. The sliding of the slider within the groove allows the second arm 200 to extend or retract relative to the first arm 100. The second arm 200 is also made of a similar lightweight, high-strength material as the first arm 100, ensuring the stability and portability of the overall structure. Alternatively, the second arm 200 and the first arm 100 can be interlocked to achieve a sliding fit. It should be noted that the names "first arm 100" and "second arm 200" do not limit the shape of the corresponding structure; other names such as "first rod" and "second rod," "first cylinder" and "second cylinder," etc., can also be used.

[0043] The locking component 300 is disposed on one of the first arm 100 and the second arm 200. In this embodiment, it is assumed that the locking component 300 is disposed on the first arm 100 (of course, it is also feasible to dispose of it on the second arm 200, the principle is the same). Multiple toothed grooves 300C are provided on the other of the first arm 100 and the second arm 200, namely the second arm 200. The multiple toothed grooves 300C are sequentially spaced along the sliding direction of the second arm 200. The shape of the toothed grooves 300C can be a right-angled trapezoid, with the hypotenuse facing the extension direction of the second arm 200. This design facilitates smoother insertion and withdrawal of the locking pawl 310, and at the same time, in the locked state, it can better withstand external forces from different directions, ensuring the stability of the locking.

[0044] The locking assembly 300 comprises a locking pawl 310 and a reset member 320. As an example, the locking pawl 310 is rotatably connected to the first arm 100 via a pin, and a torsion spring is mounted on the pin as the reset member 320. One end of the torsion spring is fixed to the first arm 100, and the other end acts on the locking pawl 310 to provide a force that resets the locking pawl 310 towards the locking position. The locking pawl 310 can be rotated to switch between a locked position and an unlocked position. In the locked position, the locking pawl 310 inserts into the toothed groove 300C, fixing the second arm 200 relative to the first arm 100. In the unlocked position, the locking pawl 310 disengages from the toothed groove 300C, allowing the second arm 200 to extend and retract relative to the first arm 100. Based on the multiple toothed grooves 300C, the locking pawl 310 can be inserted into different toothed grooves 300C to make the second arm 200 statically fixed relative to the first arm 100 at different positions.

[0045] When the user needs to adjust the length of the telescopic component of the photographic equipment, they manually rotate the locking pawl 310 in the unlocking direction to overcome the force of the reset element 320 (such as a torsion spring), causing the locking pawl 310 to disengage from the toothed groove 300C. At this time, the second arm 200 is in the unlocked state and can freely extend and retract relative to the first arm 100. After the user adjusts the second arm 200 to a suitable length according to actual needs, they release the locking pawl 310. Under the action of the reset element 320 (such as a torsion spring), the locking pawl 310 automatically rotates back to the locked position and inserts into the corresponding toothed groove 300C, thereby fixing the second arm 200 statically relative to the first arm 100, completing the length adjustment and locking operation. Furthermore, the reset component 320 continuously provides a resetting force to the locking pawl 310 toward the locking position. During normal use, even if subjected to certain external vibrations or impacts, the locking pawl 310 can always remain inserted into the tooth groove 300C under the action of the reset component 320, ensuring that the relative fixation between the second arm 200 and the first arm 100 is stable and reliable, avoiding the impact on the normal use of the photographic equipment due to accidental loosening, and providing a solid guarantee for the stable support and expansion of photographic equipment in various scenarios.

[0046] The telescopic assembly of the photographic equipment in this embodiment eliminates the numerous cumbersome parts found in traditional complex locking structures. It utilizes only a simple locking pawl 310 engaged with multiple toothed grooves 300C, significantly simplifying the overall structure. This not only reduces the number of parts, lowering assembly difficulty and cost during manufacturing, but also makes the internal structure more compact, effectively reducing the structural space occupied and thus contributing to a smaller overall product size, making it easier for users to carry and store. Furthermore, users can easily switch between the locked and unlocked positions simply by rotating the locking pawl 310. The entire operation is simple and intuitive, requiring no complicated unlocking steps, greatly saving users' time and effort, and significantly improving ease of use and user experience.

[0047] In some embodiments, refer to Figure 2 and Figure 4 The first arm 100 is provided with a slide rail 100D, and the second arm 200 is slidably engaged with the slide rail 100D and is slidably disposed on the first arm 100.

[0048] The locking assembly 300 is disposed on the first arm 100, and a plurality of toothed grooves 300C are formed on the second arm 200.

[0049] In this embodiment, the slide rail 100D on the first arm 100 can be closed at one end and open at the other. The second arm 200 is inserted into the slide rail 100D from the open end and forms a sliding engagement with the slide rail 100D. The second arm 200 can slide along the slide rail 100D to extend or retract. The slide rail 100D can be manufactured with high-precision technology to ensure surface flatness and smoothness. Common shapes include rectangular or dovetail shapes, which can provide stable and precise guidance for the sliding of the second arm 200, ensuring that the second arm 200 will not wobble or deviate during the extension and retraction process, making the extension and retraction components of the photographic equipment more stable and reliable when adjusting the length. Furthermore, by setting the locking component 300 on the first arm 100 and engaging with the toothed groove 300C on the second arm 200, a simple and effective locking method is formed.

[0050] In some embodiments, refer to Figures 3 to 5 The surface of the first arm body 100 is provided with a receiving cavity 100Q and a first cavity opening disposed opposite to the bottom wall of the receiving cavity 100Q, and the locking assembly 300 is located in the receiving cavity 100Q.

[0051] The cavity wall of the receiving cavity 100Q is provided with a first opening 10 and is connected to the slide rail 100D through the first opening 10. One end of the locking pawl 310 is a rotating end and the other end is a holding end that is adapted to the tooth groove 300C. The holding end passes through the slide rail 100D from the first opening 10.

[0052] In this embodiment, the surface of the first arm 100 is specially designed with a receiving cavity 100Q. This receiving cavity 100Q has a specific shape and size, designed to provide a dedicated and stable installation space for the locking assembly 300. The receiving cavity 100Q has a first opening opposite to the bottom wall of the cavity, which facilitates the installation and subsequent maintenance of the locking assembly 300. The receiving cavity 100Q is formed using high-precision molds and precision machining processes to ensure the flatness and dimensional accuracy of the cavity wall, so as to ensure that the locking assembly 300 can be accurately installed and fits tightly with the overall structure of the first arm 100 without affecting the structural strength of the first arm 100. At the same time, the cavity wall of the receiving cavity 100Q is provided with a first opening 10, which cleverly connects the receiving cavity 100Q with the slide 100D. This connection design provides the necessary channel for the movement of the locking pawl 310.

[0053] The locking assembly 300 is housed within the receiving cavity 100Q of the first arm body 100. The locking pawl 310 in the locking assembly 300 has a unique structure, with one end being a rotating end that is rotatably connected to the first arm body 100 via a pin. The other end of the locking pawl 310 is a retaining end that is adapted to the toothed groove 300C. This retaining end passes through the first opening 10 into the slide rail 100D, thereby enabling precise engagement with the toothed groove 300C on the second arm body 200.

[0054] The design of the receiving cavity 100Q and the first cavity opening on the first arm body 100 makes the installation of the locking component 300 extremely convenient. Installers can easily insert the locking component 300 into the receiving cavity 100Q and secure it through the first cavity opening, greatly improving production assembly efficiency. Simultaneously, the design of the receiving cavity 100Q and the slide rail 100D connected through the first opening 10 cleverly achieves the engagement of the locking pawl 310 and the toothed groove 300C without occupying excessive additional space, making the internal structure of the entire product more compact and rational.

[0055] In some embodiments, refer to Figures 3 to 5 The rotating end extends with a pressing part 310B, which protrudes from the first cavity and is used to rotate the locking pawl 310 when subjected to external force. The pressing part 310B is ergonomically designed, and can be flat or curved for easy finger pressing. The pressing part 310B is integrally formed with the rotating end and is made of the same material as the locking pawl 310, ensuring overall strength and durability. Users can easily rotate the locking pawl 310 by simply pressing the pressing part 310B with their fingers, without the need for additional tools. Compared to traditional methods requiring complex unlocking, this design allows users to quickly unlock and lock the second arm 200. For example, in outdoor shooting scenarios, photographers need to quickly adjust the length of their equipment. By pressing the pressing part 310B, they can quickly unlock and adjust the length of the second arm 200, and then quickly lock it after shooting, greatly improving operational efficiency and meeting users' needs for rapid operation in different scenarios.

[0056] In some embodiments, refer to Figure 3 , Figure 5 and Figure 6 The locking assembly 300 also includes a mounting base 330, and the locking pawl 310 is rotatably connected to the mounting base 330 via a rotating shaft. The mounting base 330 is adapted to the receiving cavity 100Q, and the locking assembly 300 is detachably received in the receiving cavity 100Q via the mounting base 330.

[0057] The reset component 320 includes a reset torsion spring, which is sleeved on the rotating shaft. One end of the reset torsion spring abuts or connects to the mounting base 330, and the other end abuts or connects to the locking pawl 310.

[0058] In this embodiment, the locking assembly 300 adds a key component, the mounting base 330, and the locking pawl 310 is rotatably connected to the mounting base 330 via a rotating shaft. The shape and size of the mounting base 330 are adapted to the receiving cavity 100Q, allowing the locking assembly 300 to be detachably housed within the receiving cavity 100Q via the mounting base 330. This detachable design greatly facilitates subsequent maintenance, repair, and component replacement. The detachable connection between the mounting base 330 and the first arm body 100 can be achieved using screws, snap-fit ​​connections, etc., selected according to actual needs. The mounting base 330 can be made of high-strength engineering plastics or lightweight alloy materials, ensuring structural strength while minimizing its own weight to avoid excessive impact on the overall weight of the telescopic assembly. The reset component 320 uses a reset torsion spring, which is sleeved on the rotating shaft. One end of the return torsion spring is tightly abutted against the mounting base 330 or connected through a specific connection structure, while the other end abuts against or is connected to the locking pawl 310. This connection method enables the return torsion spring to continuously provide a stable force for the locking pawl 310 to return to the locking position.

[0059] The locking assembly 300 is detachably connected to the receiving cavity 100Q via the mounting base 330, which greatly improves assembly efficiency during product manufacturing and assembly. Installers can pre-assemble components such as the locking pawl 310 and the return torsion spring on the mounting base 330 before installing the entire assembly into the receiving cavity 100Q, reducing the difficulty and complexity of direct installation within the cavity 100Q. During product use, if the locking assembly 300 malfunctions, such as wear on the locking pawl 310 or failure of the return torsion spring, the user or maintenance personnel can easily remove the mounting base 330 from the receiving cavity 100Q to repair or replace the relevant components individually.

[0060] In some embodiments, refer to Figure 3 , Figure 5 and Figure 6 The mounting base 330 is provided with a mounting cavity 330Q and a second cavity opening disposed opposite to the bottom wall of the mounting cavity 330Q, and the locking pawl 310 is accommodated in the mounting cavity 330Q;

[0061] The pressing part 310B passes through the second cavity opening to be exposed from the first cavity opening. The bottom wall of the mounting cavity 330Q is provided with a second opening 20, which is aligned with the first opening 10. The holding end passes through the second opening 20 and enters the slide 100D through the first opening 10.

[0062] In this embodiment, the mounting base 330, as a key component of the locking assembly 300, is provided with a mounting cavity 330Q and a second opening opposite to the bottom wall of the mounting cavity 330Q. The locking pawl 310 is housed in the mounting cavity 330Q, and the size and shape of the mounting cavity 330Q are precisely matched to the locking pawl 310, providing a stable space for the rotation of the locking pawl 310. The pressing part 310B passes through the second opening and is then exposed through the first opening of the first arm 100. This design allows the user to directly and conveniently operate the pressing part 310B to control the locking pawl 310. The bottom wall of the mounting cavity 330Q is provided with a second opening 20, which is aligned with the first opening 10 on the wall of the first arm 100 housing cavity 100Q. The locking pawl 310, with its retaining end adapted to the toothed groove 300C, passes through the second opening 20 and enters the slide rail 100D through the first opening 10, thus enabling precise engagement with the toothed groove 300C on the second arm body 200. The precise accommodation of the locking pawl 310 in the mounting cavity 330Q of the mounting base 330, and the alignment of the second opening 20 with the first opening 10, make the installation and operation of the locking pawl 310 more stable. During use, even if the photographic equipment is subjected to significant external vibration or impact, the locking pawl 310 maintains a stable rotational state within the mounting cavity 330Q without wobbling or shifting.

[0063] In some embodiments, the mounting base 330 has connecting holes for inserting fasteners that detachably connect the mounting base 330 to the first arm body 100. In this embodiment, the mounting base 330 has connecting holes, the number of which is reasonably set according to the size of the mounting base 330 and actual force requirements, typically two or four, symmetrically distributed. The diameter of the connecting holes matches the selected fasteners for inserting the fasteners that detachably connect the mounting base 330 to the first arm body 100. Common fasteners are bolts or screws. By passing the bolts or screws through holes in the wall of the first arm body 100 receiving cavity 100Q and screwing them into the connecting holes, a secure connection between the mounting base 330 and the first arm body 100 is achieved, which is simple to operate and provides a strong connection.

[0064] In some embodiments, refer to Figure 2 and Figure 3 The first arm body 100 is provided with a cover plate 400, the cover plate 400 is provided with a third opening 30, the cover plate 400 covers the first cavity, and the pressing part 310B extends out from the third opening 30 of the cover plate 400 for exposure.

[0065] In this embodiment, the cover plate 400 is made of the same or matching aluminum alloy material as the first arm 100, and its dimensions are precisely matched to the first cavity opening through precision machining. The cover plate 400 is fastened to the first cavity opening by bolts, clips, or adhesive, providing further protection for the receiving cavity 100Q. The cover plate 400, covering the first cavity opening, provides an additional protective barrier for the locking assembly 300 within the receiving cavity 100Q. During daily use, especially in complex environments such as outdoors, it can, to a certain extent, prevent debris from entering the receiving cavity 100Q, avoiding interference with precision components such as the locking pawl 310 and the return torsion spring, thereby reducing wear and tear and the failure rate of components, and extending the service life of the locking assembly 300. Furthermore, the cover plate 400 makes the appearance of the first arm body 100 more complete and aesthetically pleasing. It fills the gap in the first cavity opening, making the surface of the first arm body 100 smoother and more seamless, without appearing abrupt due to the presence of the cavity opening. This not only enhances the overall visual effect of the product but also highlights the precision of the product's design and manufacturing process, strengthens the product's market competitiveness, and meets users' pursuit of product appearance quality.

[0066] In some embodiments, refer to Figure 3 The surface of the pressing part 310B has a textured structure; and / or,

[0067] Reference Figure 5 An angle is formed between the pressing part 310B and the locking pawl 310, with the angle ranging from 90° to 150°.

[0068] In this embodiment, optionally, as follows: Figure 3 As shown, the surface of the pressing part 310B has a textured structure. This texture can be horizontal, vertical, diamond-shaped, or wavy, formed on the surface of the pressing part 310B through specific mold pressing or laser etching processes. The depth and width of the texture are carefully designed to provide sufficient friction without causing discomfort to the user's fingers. During operation, especially when shooting outdoors, users may encounter situations such as sweaty hands or humid environments. In these situations, a smooth pressing part 310B can easily cause fingers to slip, affecting the accuracy and efficiency of operation. The texture effectively solves this problem, allowing users to press the pressing part 310B more stably, ensuring that each operation accurately rotates the locking pawl 310, achieving fast and precise unlocking and locking, and improving the operational reliability of the product in complex usage environments.

[0069] Optionally, such as Figure 5As shown, an angle is formed between the pressing part 310B and the locking pawl 310, with the angle ranging from 90° to 150°. During manufacturing, the angle is ensured to be within the specified range through an integrated molding process or precise welding of the locking pawl 310 and the pressing part 310B. The 90°–150° angle between the pressing part 310B and the locking pawl 310 conforms to ergonomic principles. When the user presses the pressing part 310B, this angle allows the fingers to be in a natural and comfortable position, reducing hand muscle fatigue. Compared to a design where the pressing part 310B and the locking pawl 310 are on the same straight line, this angled design allows the user to drive the locking pawl 310 to rotate with less force. For example, when frequently adjusting the length of the telescopic component of photographic equipment, the user can complete the operation more easily, reducing the difficulty of operation and physical exertion, further improving the user experience.
