[0002] In the field of photography, shooting scenarios and needs are diverse. From recording vast landscapes to capturing delicate close-ups, tracking moving objects, and using rotating shots to present unique perspectives, all these situations place stringent demands on photography tripods. To meet these complex needs, most photography tripods on the market feature the characteristic of being able to swing freely in multiple directions around a support point, allowing photographers to flexibly carry out their creative work.

[0003] In long-duration static shooting scenarios, the tripod must remain upright and stable. Therefore, an upright locking device that can easily switch between free swing and upright locking is crucial. Moreover, when changing shooting direction, the camera equipment on the tripod head is prone to shaking and imbalance. Currently, most tripods on the market have complex locking mechanisms, with cumbersome unlocking and locking procedures that are difficult to complete in one go. This results in low work efficiency in scenarios where frequent switching between free swing and upright locking is required. Utility Model Content

[0031] Example 1:

[0032] Please refer to Figures 1 to 3 This application provides a convenient unlocking tripod, which simplifies the structure of existing tripods. Users can quickly lock and unlock the tripod with simple operations, improving the ease of use. This application is described with the tripod in an upright position.

[0033] Specifically, the tripod includes a locking assembly 1 and a mounting bracket 2. The mounting bracket 2 has a mounting groove 21 on its top and a limiting groove 22 on its inner sidewall. The locking assembly 1 includes a driving member 6, a sliding member 7, and a locking member 8. One end of the driving member 6 is rotatably connected to the mounting bracket 2. The sliding member 7 is slidably fitted into the mounting groove 21 in a vertical direction, and the driving member 6 partially abuts against the sliding member 7 to press it down. The locking member 8 passes through the sliding member 7 and is fixed within the mounting groove 21, and the sliding member 7 is used to lock the locking member 8. A limiting structure 9 is provided on the side of the sliding member 7. When the tripod is in the locked state, the limiting structure 9 disengages from the limiting groove 22; when the tripod is in the unlocked state, the limiting structure 9 engages with the limiting groove 22.

[0034] Here, one end of the drive component 6 is rotatably connected to the mounting bracket 2. When unlocking the tripod, the user presses down on the drive component 6 to press the sliding component 7, causing the sliding component 7 to slide vertically within the mounting groove 21. This disengages the top of the sliding component 7 from the bottom of the locking component 8. When the limiting structure 9 on the side of the sliding component 7 slides along the limiting groove 22 and engages with the limiting position in the limiting groove 22, the tripod is unlocked. When the tripod is locked, the limiting structure 9 on the side of the sliding component 7 disengages from the limiting groove 22, causing the sliding component 7 to return to its original position and engage with the bottom of the limiting position in the locking component 8. Compared to the complex locking structure of traditional tripods, this application greatly simplifies the manufacturing process and assembly flow, reduces costs, and thus simplifies the locking and unlocking steps of the tripod, improving work efficiency and ease of use.

[0035] Please refer to Figure 2 In one specific embodiment, the tripod further includes a torsion spring 3. A column 23 is fixed in the middle of the mounting groove 21, a locking member 8 is fixedly connected to the column 23, a sliding member 7 is slidably sleeved on the outside of the column 23 in a vertical direction, and the torsion spring 3 is sleeved on the outside of the column 23, with both ends of the torsion spring 3 abutting against the bottom wall of the mounting groove 21 and the sliding member 7, respectively. While providing elasticity, the torsion spring 3 also enhances the structural stability of the entire locking assembly 1 to a certain extent. Through its connection with the column 23, the bottom wall of the mounting groove 21, and the sliding member 7, the torsion spring 3 makes the connection between the components tighter, reducing shaking and loosening between components, and helping to improve the overall durability and reliability of the tripod.

[0036] When the tripod is unlocked, the drive component 6 presses down on the slider 7, causing the torsion spring 3 to undergo elastic deformation. When the drive component 6 stops pressing down on the slider 7, the torsion spring 3 uses its elastic potential energy to drive the slider 7 to return to its original position, causing it to abut against the bottom of the locking component 8. This achieves automatic reset and locking of the tripod, eliminating the need for the user to manually push the slider 7 back to its original position, further improving ease of use and simplifying the entire operation process.

[0037] In one specific embodiment, the sliding member 7 consists of an integrally formed upper part 10 and a boss part 11. Slide grooves 18 are formed through both opposite sides of the upper part 10. Connecting shafts 25 protrude from both sides of the column 23 corresponding to the slide grooves 18, with each connecting shaft 25 passing through one of the slide grooves 18. One end of the driving member 6 is sleeved on the connecting shaft 25, and the driving member 6 is rotatable around the connecting shaft 25. When the driving member 6 is pressed, the bent portion of the driving member 6 abuts against the boss part 11.

[0038] Here, the slider 7 can slide precisely vertically within the groove 18 along the connecting shaft 25 on the column 23. The cooperation between the groove 18 and the connecting shaft 25 serves as a guide, ensuring that the slider 7 can only move in the predetermined vertical direction, limiting its displacement in other directions, thereby ensuring the accuracy of the tripod locking and unlocking actions. At the same time, this cooperation method also increases the contact area between the slider 7 and the column 23, making the sliding process smoother and reducing shaking and jamming.

[0039] One end of the drive component 6 is rotatably connected to two connecting shafts 25. When the drive component 6 is pressed, its curved portion abuts against the boss portion 11, allowing the drive component 6 to effectively transmit external force to the slider 7. The rotatable connection between the drive component 6 and the connecting shafts 25 provides the drive component 6 with a flexible rotation fulcrum, allowing the user to operate the drive component 6 with simple rotational movements. The abutment between the curved portion of the drive component 6 and the boss portion 11 of the slider 7 ensures that when the drive component 6 is pressed, force is accurately applied to the slider 7, pushing the slider 7 down vertically to unlock the tripod. This connection and abutment method makes the drive component 6's drive of the slider 7 more direct and efficient, and the user's operation more convenient and effortless.

[0040] Please refer to Figure 2 and Figure 3 In one specific embodiment, the limiting groove 22 is L-shaped, and the limiting structure 9 protrudes from the outer wall of the boss portion 11. When the driving member 6 is pressed, the limiting structure 9 slides along the vertical end of the limiting groove 22 and engages with the horizontal end of the limiting groove 22.

[0041] The L-shaped limiting groove 22 cooperates with the limiting structure 9 on the outer wall of the boss portion 11 to precisely limit the position of the sliding member 7 when the tripod is unlocked. When the driving member 6 is pressed, the sliding member 7 drives the limiting structure 9 to slide along the vertical end of the limiting groove 22 first. When the limiting structure 9 is engaged with the horizontal end of the limiting groove 22, it indicates that the sliding member 7 has reached the accurate unlocking position, and the tripod is in a stable unlocked state.

[0042] When the tripod needs to be locked, the user can rotate the drive component 6 horizontally. The drive component 6 drives the slider 7 to rotate horizontally, causing the limiting structure 9 to slide from the horizontal end of the limiting groove 22 to the vertical end. Under the elastic potential energy of the torsion spring 3, it slides upward until the top of the slider 7 abuts against the bottom of the locking component 8, thus locking the tripod. The limiting structure 9 slides within the limiting groove 22, restricting the movement of the slider 7 in other unexpected directions. This ensures that the tripod remains stable after unlocking or locking, preventing it from shaking or deforming due to slight external forces, thereby improving the stability and reliability of the tripod during use.

[0043] Furthermore, the end of the limiting structure 9 furthest from the sliding member 7 is curved. This curved design allows the limiting structure 9 to slide more smoothly within the limiting groove 22, reducing jamming, and also facilitates a smoother engagement when it engages with the horizontal end of the limiting groove 22. Similarly, the curved design helps the limiting structure 9 disengage from the horizontal end of the limiting groove 22, reducing operational resistance and making the unlocking and locking process of the tripod more convenient and smooth. The curved surface and the limiting groove 22 have line or point contact, which, compared to planar contact, generates less friction during sliding and engagement, effectively reducing wear between the limiting structure 9 and the limiting groove 22 and extending their service life.

[0044] In one specific embodiment, the locking member 8 includes a ball 19 and a sleeve 20. The bottom end of the ball 19 passes through the sliding member 7 and is fixed inside the column 23. The sleeve 20 is rotatably sleeved on the outside of the ball 19, and the top of the sliding member 7 is used to abut against the bottom of the sleeve 20.

[0045] The sleeve 20 is rotatably fitted onto the outside of the sphere 19, allowing the sleeve 20 to rotate flexibly relative to the sphere 19. During tripod use, this rotational flexibility can adapt to different usage scenarios and angle adjustment needs. For example, when adjusting the tripod's support angle, the sleeve 20 can rotate to adapt to different positions, thus better meeting the user's requirements for tripod posture adjustment.

[0046] The bottom end of the ball 19 passes through the slider 7 and is fixed inside the column 23, ensuring the stable installation of the ball 19 on the column 23 and providing a solid foundation for the entire locking structure. The top of the slider 7 abuts against the bottom of the sleeve 20. When the slider 7 returns to its original position, its top abuts tightly against the bottom of the sleeve 20, locking the sleeve 20 and thus restricting the movement of related components, achieving the purpose of locking the tripod. This design enables precise locking and positioning, ensuring the stability and reliability of the tripod in the locked state and preventing accidental unlocking or shaking of the tripod.

[0047] Example 2:

[0048] Please refer to Figure 4 and Figure 5 The main difference between this embodiment and Embodiment 1 is that the stand also includes a pressing member 4 and a first spring 29. The two ends of the first spring 29 abut against the bottom wall of the mounting groove 21 and the sliding member 7, respectively. The limiting groove 22 penetrates the side wall of the mounting frame 2. The pressing member 4 is slidably limited in the limiting groove 22. The side wall of the boss 11 is horizontally slidably provided with a limiting structure 9. A second spring 27 is provided between the limiting structure 9 and the boss 11. The pressing member 4 is used to abut against the limiting structure 9.

[0049] When the tripod is in the unlocked state, the limiting structure 9 slides down to the limiting groove 22 along with the slider 7. Under the elastic force of the second spring 27, the limiting structure 9 engages with the limiting groove 22 and abuts against the pressing member 4. When it is necessary to lock the tripod, the user can press the pressing member 4, causing the pressing member 4 to push the limiting structure 9 out of the limiting groove 22. At this time, the second spring 27 is compressed and stores elastic potential energy. The slider 7 slides upward under the action of the elastic potential energy of the first spring 29 until the top of the slider 7 abuts against the bottom of the limiting locking member 8, thereby locking the tripod. Here, the cooperation between the pressing member 4 and the limiting structure 9 simplifies the locking and unlocking steps of the tripod, improving work efficiency and the convenience of tripod use.

[0050] Example 3:

[0051] Please refer to Figures 6 to 9 The main difference between this embodiment and Embodiment 1 is that a connecting post 24 is provided in the middle of the mounting groove 21, the locking member 8 is fixedly connected to the top of the connecting post 24, the limiting groove 22 penetrates the side wall of the mounting frame 2, and the sliding member 7 is provided with an abutment strip 12 in the middle, which penetrates the middle of the connecting post 24. The stand also includes a third spring 5, the two ends of which abut against the bottom of the abutment strip 12 and the bottom wall of the mounting groove 21, respectively. A first through groove 26 is opened through the side wall of the connecting post 24, a second through groove 28 is opened through one side of the sliding member 7, and the other end of the driving member 6 passes through the first through groove 26, the second through groove 28, and the limiting groove 22 in sequence, and the driving member 6 abuts against the top of the abutment strip 12 to drive the sliding member 7 to slide. One end of the limiting structure 9 is movably limited in the limiting groove 22, and the other end of the limiting structure 9 is slidably connected to the driving member 6.

[0052] Here, the connecting post 24 provides support and guidance for the sliding member 7, allowing it to slide stably vertically along the connecting post 24, ensuring the accuracy of the tripod locking and unlocking actions. The abutment strip 12 passes through the middle of the connecting post 24, cooperating with the drive member 6 and the third spring 5. The drive member 6 abuts against the top of the abutment strip 12. When the user presses the drive member 6, it drives the sliding member 7 downwards via the abutment strip 12. Simultaneously, the abutment strip 12 also provides a point of application for the third spring 5, allowing it to apply an upward elastic force to the sliding member 7 through the abutment strip 12. The first through groove 26 and the second through groove 28 provide rotation space for one end of the drive member 6 while limiting its rotation range, ensuring that the drive member 6 accurately contacts and moves the abutment strip 12 during rotation, guaranteeing the stability and accuracy of the drive member 6's driving action on the sliding member 7.

[0053] One end of the limiting structure 9 is movably limited in the limiting groove 22, and the other end is slidably connected to the driving member 6. This connection method allows the driving member 6 to simultaneously drive the limiting structure 9 to rotate as it rotates and drives the sliding member 7 to slide down. When the tripod is unlocked, pressing the driving member 6 causes the limiting structure 9 to engage with the limiting groove 22, thus maintaining the unlocked state of the tripod. When the tripod needs to be locked, pressing one end of the limiting structure 9 that protrudes from the driving member 6 pushes the limiting structure 9 away from the limiting groove 22. The sliding member 7 returns to its original position under the action of the third spring 5, allowing the sliding member 7 to smoothly abut against the bottom of the limiting member 8, completing the locking of the tripod and ensuring accurate switching between the locked and unlocked states of the tripod.

[0054] Please refer to Figure 8 and Figure 9 In one specific embodiment, the limiting structure 9 includes a limiting block 13 and a fourth spring 14. One end of the limiting block 13 is provided with an "I"-shaped limiting part 15 and a clearance groove 16, the limiting part 15 being used to abut against the groove wall of the limiting groove 22; the other end of the limiting block 13 slides through the driving member 6, and the fourth spring 14 is disposed in the driving member 6, with both ends of the fourth spring 14 abutting against the limiting block 13 and the driving member 6 respectively.

[0055] The limiting part 15 at one end of the limiting block 13 can abut against the side wall of the limiting groove 22. When the tripod is in the unlocked state, the limiting part 15 is engaged in the limiting groove 22 and makes tight contact with the side wall of the limiting groove 22. This structure can provide a large contact area and stable support, effectively limiting the position of the sliding member 7 and preventing its accidental movement, thereby ensuring that the tripod remains stable in the unlocked state. At this time, under the elastic action of the fourth spring 14, the other end of the limiting block 13 passes through and is limited to the end of the driving member 6 away from the connecting post 24.

[0056] When the tripod needs to be locked, the user can press the end of the limiting block 13 away from the limiting part 15, thereby pushing the limiting part 15 out of the limiting groove 22. This causes the sliding member 7 to return to its original position under the action of the third spring 5, so that the sliding member 7 abuts against the bottom of the limiting part 8, completing the locking of the tripod. At this time, the clearance groove 16 is located within the opening range of the limiting groove 22. The clearance groove 16 provides space for the rotation of the limiting block 13, reducing interference and jamming of the limiting block 13 during operation. This makes the locking and unlocking process of the tripod smoother, improves the user's operating experience, and allows the user to switch the tripod status more easily.

[0057] Furthermore, guide ramps 17 are provided on opposite sides of the limiting part 15. During locking or unlocking of the tripod, the guide ramps 17 act as guides, making the contact between the limiting block 13 and the side wall of the limiting groove 22 smoother. When the limiting block 13 approaches the limiting groove 22, the guide ramps 17 make it easier for the limiting block 13 to align with the limiting groove 22, allowing it to enter the limiting groove 22 more smoothly, thus improving the convenience and efficiency of operation.

[0058] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
