Detailed Implementation

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0021] This invention provides a connector 1, such as... Figures 1 to 11 As shown, the connecting seat 1 includes a seat body 11, a knob 12 and a stud 13; the knob 12 is rotatably mounted on the top surface of the seat body 11 about the axis of the seat body 11, and the stud 13 is rotatably mounted on the top surface of the seat body 11 about its axis. The knob 12 and the stud 13 are connected in a transmission manner so that the knob 12 drives the stud 13 to rotate when it rotates.

[0022] The connector 1 of the present invention has a knob 12 that can rotate around its axis on the top surface of the main body 11, and a stud 13 that can also rotate around its axis is installed on the top surface of the main body 11. At the same time, a transmission connection is formed between the knob 12 and the stud 13, thereby achieving the technical effect of driving the stud 13 to rotate synchronously when the knob 12 rotates. This solves the problem of inconvenience and poor user experience caused by the need to rotate the external equipment or accessories themselves, or to rotate the entire shooting bracket, in the prior art to drive the stud 13 to lock. When it is necessary to lock or loosen the external equipment, the user can drive the stud 13 to rotate simply by operating the knob 12, without having to rotate the bulky external equipment or the entire bracket, which significantly reduces the difficulty of operation, improves assembly efficiency and user convenience.

[0023] Furthermore, the base body 11, serving as the structural base for the connecting base 1, provides a stable mounting surface for the knob 12 and stud 13 on its top surface. The knob 12 is mounted in a manner that allows it to rotate around the axis of the base body 11, meaning that the rotation center of the knob 12 coincides with the central axis of the base body 11, thereby ensuring the stability and uniform force distribution during rotation. Similarly, the stud 13 is mounted on the top surface of the base body 11 in a manner that allows it to rotate around its own axis, enabling it to rotate smoothly around its own axis under the drive of the knob 12, thus allowing it to be screwed into or out of the threaded interface of external equipment. In addition, the knob 12 is exposed on the top surface of the base body 11, making it easy for users to hold and operate directly. Its surface can be designed with knurled grooves to further improve the rotational force application experience. The standard thread specification of the stud 13 can adopt the common interface standard of photographic equipment, such as 1 / 4 inch or 3 / 8 inch, ensuring compatibility with most clamping mechanisms, magnetic mechanisms, cameras, gimbals, and fill lights on the market, without specific limitations.

[0024] This invention shifts the rotation operation point from the top of the stud 13 to the knob 12 on the top surface of the base body 11. This allows the user to complete the final locking simply by continuously rotating the knob 12 after the external device has been initially fitted onto the stud 13. The entire process does not require moving the external device or the bracket body 2. This is especially suitable for shooting scenarios where space is limited or the equipment is heavy, effectively improving the human-computer interaction quality and actual user experience of the bracket.

[0025] Specifically, the connecting base 1 also includes a transmission assembly 14, which is installed in the base body 11. The transmission assembly 14 is connected to both the knob 12 and the stud 13 to transmit the rotational motion of the knob 12 to the stud 13. By adding the transmission assembly 14 to the connecting base 1 and connecting it to both the knob 12 and the stud 13, the technical effect of stably transmitting the rotational motion of the knob 12 to the stud 13 is achieved. The transmission assembly 14 acts as an intermediate medium to realize the transmission between the knob 12 and the stud 13, making the design of the transmission path and transmission ratio more flexible.

[0026] Furthermore, in one embodiment, the knob 12 is ring-shaped, and a first toothed groove 121 is provided around the inner sidewall of the knob 12; the transmission assembly 14 includes a first gear 141 and a second gear 142, the first gear 141 meshes with the first toothed groove 121, and the second gear 142 is coaxially fixedly connected to the stud 13, and the first gear 141 meshes with the second gear 142. The knob 12 is designed in a ring shape with a first toothed groove 121 around its inner sidewall. The transmission assembly 14 includes a first gear 141 and a second gear 142. The first gear 141 meshes with the first toothed groove 121, and the second gear 142 is coaxially and fixedly connected to the stud 13. The first gear 141 meshes with the second gear 142, thereby achieving the technical effect of transmitting the rotational motion of the knob 12 to the stud 13 through two stages of internal tooth meshing and gear transmission. The design of the first toothed groove 121 of the ring knob 12 makes the rotational operation of the knob 12 not limited by angle. Users can hold and rotate the knob 12 in any position, which greatly improves the convenience of operation and interactive experience. At the same time, the meshing transmission of the first gear 141 and the second gear 142 has the advantages of constant transmission ratio, high transmission efficiency and compact structure, which enables the rotation of the knob 12 to drive the stud 13 to rotate accurately and smoothly.

[0027] Furthermore, the outer wall of the annular knob 12 can be designed with knurling, ribs, or grooves to enhance grip friction, and the first tooth groove 121 on the inner wall can be a straight tooth. The first gear 141 and the second gear 142 can be machined by metal cutting or powder metallurgy, or they can be injection molded from engineering plastics. The tooth surfaces of the first tooth groove 121, the first gear 141, and the second gear 142 can be hardened or coated with a wear-resistant coating to extend their service life. In another embodiment, the knob 12 can also be irregularly shaped.

[0028] The second gear 142 has a mounting cavity 1421 with a polygonal cross-section. The stud 13 has a polygonal mounting portion 131 that fits into the mounting cavity 1421, and the polygonal mounting portion 131 is inserted into the mounting cavity 1421. By creating a polygonal mounting cavity 1421 on the second gear 142 and providing a polygonal mounting portion 131 on the stud 13 that fits into the mounting cavity 1421, the circumferential fixation between the stud 13 and the second gear 142 is achieved through polygonal engagement.

[0029] Furthermore, the cross-section of the mounting cavity 1421 can be an equilateral triangle, square, regular hexagon, or other polygon. The external dimensions of the polygonal mounting part 131 need to form a clearance fit or transition fit with the mounting cavity 1421. The fit clearance is usually controlled between 0.05 and 0.15 mm to ensure torque transmission efficiency and facilitate insertion. The polygonal mounting part 131 and the main body of the stud 13 can be integrally machined, or they can be assembled by welding or threaded connection.

[0030] Furthermore, the connecting seat 1 also includes a locking member 15 and a first elastic member 16. The top surface of the seat body 11 is provided with a telescopic hole 1711. The first elastic member 16 and the locking member 15 are installed inside the seat body 11. The first elastic member 16 is connected to the stud 13 to drive the stud 13 to move along its axial direction and extend out of the telescopic hole 1711. The locking member 15 is used to lock the stud 13 when the stud 13 retracts back into the mounting cavity 1421. By adding a locking element 15 and a first elastic element 16, and opening a telescopic hole 1711 on the top surface of the base body 11, the first elastic element 16 and the locking element 15 are installed inside the base body 11. The first elastic element 16 is connected to the stud 13 to drive the stud 13 to move along the axis and extend out of the telescopic hole 1711. At the same time, the locking element 15 locks the stud 13 when it retracts back into the mounting cavity 1421. This achieves the technical effect that the stud 13 has both automatic extension and controllable locking states within the base body 11. The elastic driving force provided by the first elastic element 16 allows the stud 13 to automatically extend out of the telescopic hole 1711 in the unlocked state, making it easy for the user to quickly align the threaded hole of the external device with the stud 13 for initial fitting. The locking element 15 can lock the stud 13 in the retracted state when it is pressed back into the mounting cavity 1421 and is not needed, preventing the stud 13 from accidentally extending and causing bumps or interference. This design combines telescopic and locking mechanisms, allowing the stud 13 to flexibly switch between retracted and extended states, thus improving the product's portability and safety.

[0031] Furthermore, the first elastic element 16 can be a compression spring, which can be sleeved on the outer periphery of the stud 13, with one end abutting against the sleeve post 112 of the inner plate 111 of the seat body 11, and the other end abutting against the bottom groove of the stud 13, thereby continuously applying an outward elastic thrust to the stud 13; the telescopic hole 1711 is opened on the top surface of the seat body 11, and its diameter should be slightly larger than the diameter of the stud 13 to allow the stud 13 to extend and retract smoothly.

[0032] When the stud 13 extends from the telescopic hole 1711 to its maximum stroke, the polygonal mounting portion 131 abuts against the inner periphery of the telescopic hole 1711. By setting a limiting relationship where the polygonal mounting portion 131 abuts against the inner periphery of the telescopic hole 1711 when the stud 13 extends to its maximum stroke, the mechanical limiting of the stud 13's extension stroke and the technical effect of preventing it from coming out are achieved. When the polygonal mounting portion 131 extends to its limit position, it forms a physical block against the inner periphery of the telescopic hole 1711, preventing the stud 13 from continuing to move outward, effectively preventing the stud 13 from completely coming out of the telescopic hole 1711 under the continuous thrust of the first elastic member 16. At the same time, this limiting structure is implemented using the existing polygonal mounting portion 131 on the stud 13, eliminating the need for additional limiting parts, simplifying the structure and reducing manufacturing costs.

[0033] Furthermore, the outer diameter of the polygonal mounting portion 131 is larger than the diameter of the telescopic hole 1711, or the inner periphery of the telescopic hole 1711 is provided with an inwardly protruding limiting flange, so that the polygonal mounting portion 131 cannot pass through when it moves axially to the position of the telescopic hole 1711. The maximum extension stroke of the stud 13 is determined by the abutment position of the polygonal mounting portion 131 and the inner periphery of the telescopic hole 1711. This stroke length must meet the operational requirements of the threaded hole of the external equipment to fit the stud 13. It can usually be designed so that the threaded section of the stud 13 is completely exposed on the top surface of the seat body 11.

[0034] The connecting seat 1 includes an inner seat 17, which includes a top plate 171 and an annular edge 172 connected to the inner side of the top plate 171. One or more first gears 141 are provided, and the annular edge 172 has mounting slots 1721 corresponding to the number of first gears 141. The first gears 141 are disposed in the mounting slots 1721. The second gears 142 are installed in the annular edge 172. Specifically, the annular edge 172 has two symmetrically arranged mounting slots 1721, and there are two first gears 141, which are respectively disposed in the two mounting slots 1721. The second gears 142 are installed in the annular edge 172. The annular edge 172 is inserted into the knob 12, and the top plate 171 covers the knob 12. The sides of the two first gears 141 protrude from the outer side of the annular edge 172 and mesh with the first tooth grooves 121. By setting an inner sleeve 17 including a top plate 171 and an annular edge 172, and symmetrically opening two mounting slots 1721 on the annular edge 172, two first gears 141 are respectively set in the two mounting slots 1721, and the second gear 142 is installed in the annular edge 172, so that the annular edge 172 is inserted into the knob 12 and the top plate 171 covers the knob 12. At the same time, the sides of the two first gears 141 protrude from the outer side of the annular edge 172 and mesh with the first tooth groove 121, thereby achieving the technical effect of modular integrated installation of the transmission component 14 and the inner and outer double-layer nested structure of the knob 12. The inner seat sleeve 17, as an independent component, centrally arranges the first gear 141 and the second gear 142 within the space of the ring edge 172, simplifying the dispersed installation process inside the seat body 11, improving assembly efficiency and transmission accuracy. The structure of the ring edge 172 being inserted into the knob 12 and the first gear 141 protruding and meshing allows the rotation of the knob 12 to be simultaneously transmitted to the second gear 142 through the symmetrically arranged first gear 141 on both sides, forming a balanced transmission layout with multi-point force, reducing the risk of eccentric load in unilateral transmission. At the same time, the top plate 171 covering the knob 12 serves as an axial limit and top sealing function, improving the compactness and appearance integrity of the structure, while also enabling the rotational installation of the knob 12.

[0035] Furthermore, the inner sleeve 17 can be made of metal stamping, aluminum alloy die casting, or engineering plastic injection molding. The metal inner sleeve 17 has higher structural strength and dimensional stability, while the plastic inner sleeve 17 has the advantages of lightweight and good insulation. The top plate 171 can be circular, and the annular edge 172 extends downward from the inner side of the top plate 171, with its outer diameter slightly smaller than the inner diameter of the annular knob 12 to form an insertion gap. The height of the annular edge 172 must meet the axial installation space requirements of the first gear 141 and the second gear 142. Two mounting slots 1721 are symmetrically arranged on the annular edge 172, and can be rectangular, arc-shaped, or irregularly shaped openings, their dimensions of which must meet the radial protrusion and rotation space requirements of the first gear 141. The second gear 142 is installed in the central area of ​​the annular edge 172 and can be supported by a central shaft or bearing. Its mounting cavity 1421 is opened towards the top plate 171 to facilitate the insertion of the polygonal mounting portion 131 of the stud 13. After the ring rim 172 is inserted into the knob 12, the side of the teeth of the first gear 141 protrudes from the outer side of the ring rim 172 and meshes with the first tooth groove 121 on the inner sidewall of the knob 12. In one embodiment, after the top plate 171 is placed on the knob 12, it can be fixed to the seat body 11 by screws and clips.

[0036] The connecting seat 1 also includes a lower seat sleeve 18, which is installed at the bottom of the ring edge 172. A sliding groove 181 is provided on the lower seat sleeve 18, and the locking member 15 is slidably installed in the sliding groove 181. A locking hole 151 is provided on the locking member 151, and a locking part 1511 is provided on the side wall of the locking hole 151. A stud 13 is inserted into the locking hole 151, and a locking groove 132 is provided on the side of the stud 13 corresponding to the locking part 1511. A second elastic member 19 is provided between the lower seat sleeve 18 and the locking member 15. The second elastic member 19 is used to drive the locking member 15 to move so that the locking part 1511 is engaged with the locking groove 132. When the stud 13 is retracted in the mounting cavity 1421, the locking part 1511 is engaged with the locking groove 132.

[0037] By adding a lower sleeve 18 installed at the bottom of the ring 172, a sliding groove 181 is opened on the lower sleeve 18 so that the locking member 15 can be slidably installed therein. A locking hole 151 is opened on the locking member 15 and a locking part 1511 is provided on its side wall so that the stud 13 is inserted into the locking hole 151 and a locking groove 132 is opened on the side corresponding to the locking part 1511. At the same time, a second elastic member 19 is provided between the lower sleeve 18 and the locking member 15 to drive the locking member 15 to move so that the locking part 1511 is engaged with the locking groove 132, thereby achieving the technical effect of elastic locking and sliding unlocking of the stud 13 in the retracted state. The lower sleeve 18, serving as the mounting base for the locking mechanism, forms an upper and lower modular assembly with the inner sleeve 17. The slide groove 181 provides precise linear guidance for the locking member 15. The elastic locking force provided by the second elastic member 19 allows the locking part 1511 to automatically engage with the locking groove 132, achieving reliable locking of the stud 13. The user only needs to overcome the elastic force to drive the locking member 15 to slide, thereby disengaging the locking part 1511 from the locking groove 132 and unlocking the device. The entire locking and unlocking process is simple to operate and responds quickly. In the locked state, the stud 13 is firmly restricted to the retracted position and will not be accidentally extended due to vibration or accidental contact. The second elastic member 19 can be a compression spring, which can be disposed between one end of the slide groove 181 and the locking member 15, continuously applying an elastic force towards the locking member 15 in the engaging direction.

[0038] In one embodiment, such as Figure 10 and Figure 11 As shown, the lower seat sleeve 18 and the inner seat sleeve 17 can be connected by screws. The lower seat sleeve 18 is further fixed to the inner plate 111 inside the seat body 11 by screws, thereby realizing the assembly of the various components of the connecting seat 1. In one embodiment, the lower seat sleeve 18 is provided with a first shaft post 182, which passes through the bottom of the ring edge 172 into the mounting slot 1721. The first gear 141 is sleeved on the first shaft post 182, and the top of the first shaft post 182 is provided with a plug-in post 1821, which is inserted into the plug-in hole 17211 on the top surface of the mounting slot 1721. In this way, not only can the installation of the first gear 141 be realized, but also the assembly between the lower seat sleeve 18 and the inner seat sleeve 17 can be realized.

[0039] In another embodiment, such as Figure 12 and Figure 13 As shown, the mounting slot 1721 has an opening on the side near the lower sleeve 18. The lower sleeve 18 has a protruding insertion part 183 facing the mounting slot 1721. The insertion part 183 is inserted into the mounting slot 1721 through the opening. A second shaft post 1831 is provided on the insertion part 183. The first gear 141 is sleeved on the second shaft post 1831 and located inside the mounting slot 1721. The end of the second shaft post 1831 is inserted into the insertion hole 17211 of the mounting slot 1721, thereby realizing the installation of the first gear 141.

[0040] In one embodiment, the inner sidewall of the knob 12 is provided with a driving protrusion 122, which is correspondingly provided with one end of the locking member 15, so as to drive the locking member 15 to move when the knob 12 is rotated, thereby causing the locking part 1511 to disengage from the locking groove 132. By providing a driving protrusion 122 on the inner wall of the knob 12, and aligning the driving protrusion 122 with one end of the locking member 15, the knob 12 is rotated to push the locking member 15 to move, thereby disengaging the locking part 1511 from the locking groove 132. The driving protrusion 122 converts the rotational motion of the knob 12 into a linear driving force on the locking member 15, integrating the unlocking operation of the stud 13 with the rotation operation of the knob 12. Users do not need to search for and operate a separate unlocking button 152 or lever; they only need to rotate the knob 12 according to normal usage habits to automatically unlock while the stud 13 is rotating. This simplifies the operation steps and improves the continuity of use. At the same time, the mechanical linkage between the driving protrusion 122 and the locking member 15 ensures that the unlocking action is triggered synchronously with the rotation of the knob 12, preventing damage to the mechanism caused by forced operation due to forgetting to unlock.

[0041] Specifically, the driving protrusion 122 can be a block-shaped, columnar, wedge-shaped, or cam-shaped structure protruding outward from the inner wall of the knob 12. Its protrusion height and shape need to be designed according to the sliding stroke and required thrust of the locking member 15. The wedge-shaped or cam-shaped driving protrusion 122 has a progressive thrust characteristic, which makes the unlocking process of the locking member 15 smooth and effortless. The driving protrusion 122 and the inner wall of the knob 12 can be integrally injection molded or metal-cut to ensure structural strength and positional accuracy. The circumferential position of the driving protrusion 122 on the inner wall of the knob 12 needs to correspond precisely to one end of the locking member 15. When the knob 12 is in the initial position, the driving protrusion 122 and the end of the locking member 15 maintain a certain gap. After the knob 12 rotates a certain angle, the driving protrusion 122 begins to push the locking member 15 to slide. The end of the locking member 15 that is pushed can be provided with a protruding pushing protrusion 153. Furthermore, multiple drive protrusions 122 can be arranged circumferentially to enable the knob 12 to trigger unlocking at different rotational positions, or a single drive protrusion 122 can be set to clearly define the starting rotation position for unlocking. The integrated unlocking function of the knob 12 makes the operating interface of the connector 1 extremely simple, with no additional unlocking button 152 visible. All functions are achieved through the rotation of the knob 12, conforming to the minimalist design concept. At the same time, the reliability of mechanical linkage is higher than that of electronic control, ensuring stable unlocking performance in various usage environments.

[0042] Regarding the actuation of locking element 15, in another embodiment, such as Figure 1 , Figure 2 , Figure 8As shown, a button 152 is provided at one end of the locking member 15, and the button 152 is exposed on the outer side of the base body 11. By designing one end of the locking member 15 as a button 152 and exposing the button 152 on the outer side of the base body 11, the unlocking operation of the stud 13 is made visible and directly accessible. The button 152, as a human-machine interface, transforms the sliding operation of the locking member 15 into a physical interface that the user can intuitively recognize and directly press. The user does not need to understand the working principle of the internal mechanism; they can find the unlocking operation point visually. By pressing the button 152, the locking member 15 can be moved to disengage the locking part 1511 from the locking groove 132. The operation method conforms to the user's general understanding of the function of the button 152, reducing the learning cost and the threshold of use. At the same time, the button 152 being exposed on the outer side of the base body 11 allows the unlocking operation to be completed with the same hand while holding the knob 12, achieving the convenience of single-handed operation.

[0043] like Figure 12 As shown, the present invention also discloses a bracket, including the aforementioned connecting seat 1. The connecting seat 1 is applied to the bracket, thereby achieving the technical effect of the bracket having comprehensive functions such as convenient screw connection operation, retractable stud 13 storage, and flexible unlocking control. The knob 12 of the connecting seat 1 drives the stud 13 to rotate, which solves the inconvenience of traditional brackets requiring the rotation of external equipment or the entire bracket to lock. The retractable and locking function of the stud 13 allows the stud 13 to retract for protection when the bracket is carried and to automatically extend when in use, improving portability and safety.

[0044] Specifically, the bracket can take various forms such as a tripod, monopod, desktop stand, selfie stick, or cantilever bracket. The connecting seat 1 is located at the top of the bracket as an interface with external devices. The support legs or support rods of the bracket can be made of aluminum alloy, carbon fiber, or engineering plastics to achieve a balance between lightweight and high strength. The connecting seat 1 and the bracket body 2 can be connected by screws, threads, snaps, or ball joints, without specific limitations.

[0045] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of the present invention.
