Description

Technical Field

[0001] This utility model relates to the technical field of shooting equipment accessories, and in particular to an adapter and shooting system. Background Technology

[0002] With the widespread use of photography equipment in daily life, people's demand for shooting equipment (such as cameras, video cameras, etc.) is increasing. In order to improve the application of shooting equipment in different scenarios, a large number of adapters designed for shooting equipment have appeared on the market. Shooting equipment can be mounted on tripods and other support equipment through adapters.

[0003] Existing adapters use a snap-fit ​​mechanism with a compression spring, leveraging the lever principle. In a stationary state, the snap-fit ​​clamps onto the camera device under the tension of the compression spring. When an external force presses down on its tail, it pushes against the compression spring to unlock. Once the external force is removed, the snap-fit ​​automatically springs back to its original position. However, in existing adapters, the linear force of the compression spring and the rotational motion of the snap-fit ​​have different directions. During the opening and closing process, the spring force and the snap-fit's rotational trajectory do not match, easily causing a jamming or stuttering motion when installing the camera device on the adapter, resulting in a poor user experience. Utility Model Content

The torsion spring is sleeved on the rotating shaft, and the rotating shaft passes through the mounting hole and is installed on the adapter body, so that the engagement and positioning structure can rotate relative to the adapter body around the rotating shaft. The locking and positioning structure is pressed and rotates around the pivot, pressing against the torsion spring to cause it to elastically deform. After the pressing is released, the locking and positioning structure can recover under the elastic force of the torsion spring and lock onto the external shooting device.

When the first clamping arm and the second clamping arm rotate to a preset angle, the first through hole and the second through hole are coaxial.

[0012] Optionally, the second housing has a first positioning hole corresponding to the area of ​​the first clamping arm and a second positioning hole corresponding to the area of ​​the second clamping arm. The first housing has a third positioning hole corresponding to the first positioning hole and a fourth positioning hole corresponding to the second positioning hole.

The adapter can be installed on an external support device through the mounting structure. The rotating shaft is installed on the adapter body through a mounting hole, so that the locking and positioning structure can rotate relative to the adapter body around the rotating shaft. The torsion spring is sleeved on the rotating shaft. Therefore, when the locking and positioning structure is pressed and rotates around the rotating shaft, it presses against the torsion spring and causes it to undergo elastic deformation. The elastic force generated by the torsion spring is in the same direction as the rotational movement of the locking and positioning structure, which makes the locking and positioning structure reset more smoothly after the pressing is released. The locking and positioning structure can be smoothly locked onto the external shooting device, reducing the jamming situation during the installation of the external shooting device and improving the user experience.

[0019] 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 this utility model will now be described in detail with reference to the accompanying drawings.

[0020] This utility model embodiment provides an adapter, such as Figures 1 to 3 As shown, the adapter includes an adapter body 10, a torsion spring 20, and a rotating shaft 30.

[0021] Both sides of the adapter body 10 are provided with locking and positioning structures 40, and the back of the adapter body 10 is provided with a mounting structure 50 for mounting the adapter on an external support device. The locking and positioning structure 40 is provided with mounting holes 40a.

[0022] Both the torsion spring 20 and the rotating shaft 30 are correspondingly provided with the engaging and positioning structure 40. The torsion spring 20 is sleeved on the rotating shaft 30, which passes through the mounting hole 40a and is installed on the adapter body 10, so that the engaging and positioning structure 40 can rotate relative to the adapter body 10 around the rotating shaft 30. Specifically, the torsion spring 20 and the rotating shaft 30 correspond to the engaging and positioning structure 40, meaning that one engaging and positioning structure 40 is equipped with a corresponding torsion spring 20 and a rotating shaft 30.

[0023] The locking and positioning structure 40 is pressed and rotates around the rotating shaft 30, pressing against the torsion spring 20 to cause it to undergo elastic deformation. After the pressing is released, the locking and positioning structure 40 can recover under the elastic force of the torsion spring 20 and lock into the external shooting equipment.

[0024] The adapter in this embodiment comprises an adapter body 10, a torsion spring 20, and a rotating shaft 30. The adapter body 10 has locking and positioning structures 40 on both sides and a mounting structure 50 on the back. The adapter can be mounted on an external support device via the mounting structure 50. The rotating shaft 30 passes through mounting holes 40a and is mounted on the adapter body 10, allowing the locking and positioning structures 40 to rotate relative to the adapter body 10 around the rotating shaft 30. The torsion spring 20 is sleeved on the rotating shaft 30. Therefore, when the locking and positioning structure 40 is pressed and rotates around the rotating shaft 30, it presses against the torsion spring 20, causing it to elastically deform. The elastic force generated by the torsion spring 20 is in the same direction as the rotational movement of the locking and positioning structure 40, making the reset of the locking and positioning structure 40 smoother after the pressure is released. The locking and positioning structure 40 can smoothly engage with the external shooting device, reducing stuttering during the installation of the external shooting device and improving the user experience.

[0025] refer to Figures 2 to 4 In an optional embodiment of this application, the torsion spring 20 includes a first spring coil 21, a second spring coil 22, and a main spring arm 23. The main spring arm 23 connects the first spring coil 21 and the second spring coil 22. The first spring coil 21 extends with a first spring arm 24, and the second spring coil 22 extends with a second spring arm 25. The first spring arm 24 and the second spring arm 25 are both set at an angle to the main spring arm 23. The rotating shaft 30 passes through the first spring coil 21 and the second spring coil 22. The engaging and positioning structure 40 includes a rotating connecting part 41, and a mounting hole 40a is provided on the rotating connecting part 41. The rotating connecting part 41 is limited between the first spring coil 21 and the second spring coil 22. The main spring arm 23 abuts against the engaging and positioning structure 40, and the first spring arm 24 and the second spring arm 25 abut against the adapter body 10.

[0026] Specifically, the rotating shaft 30 is fitted with a first spring ring 21 and a second spring ring 22, and the rotating connection part 41 of the engaging positioning structure 40 is limited between the two spring rings. This design creates a more compact assembly relationship between the torsion spring 20, the engaging positioning structure 40, and the rotating shaft 30. The rotating connection part 41 is limited by the first spring ring 21 and the second spring ring 22, which effectively restricts the radial wobble of the engaging positioning structure 40 during rotation, ensuring its coaxiality when rotating around the rotating shaft 30. This, in turn, ensures the engaging accuracy of the engaging positioning structure 40, allowing the external shooting equipment to engage stably and reducing the risk of detachment. At the same time, the rotating connection part 41 can also limit the torsion spring 20, making full use of the internal space of the torsion spring 20, making the entire adapter structure more compact, reducing space occupation, and conforming to the design trend of lightweight and miniaturization.

[0027] For the torsion spring 20, the combination structure of the first spring coil 21, the second spring coil 22, and the main spring arm 23 allows the elastic force to be applied more evenly to the engaging and positioning structure 40. The main spring arm 23 abuts against the engaging and positioning structure 40, and the first spring arm 24 and the second spring arm 25 abut against the adapter body 10, forming a stable reaction force support point. When the main spring arm 23 pushes the engaging and positioning structure 40 to rotate, the first spring arm 24 and the second spring arm 25 will apply symmetrical counterforces to the adapter body 10, making the torsion spring 20 as a whole balanced in force, avoiding deformation or positional displacement of the spring coils due to unilateral force, and ensuring that the engaging and positioning structure 40 is more stable in force during reset. In addition, the first spring arm 24 and the second spring arm 25 are set at an angle to the main spring arm 23, and the elastic force parameters of the torsion spring 20 can be changed by setting an appropriate angle according to actual needs.

[0028] In an optional embodiment of this application, reference is made to Figure 2 The locking and positioning structure 40 also includes a buckle 42 integrally formed with the rotating connection part 41. The end of the buckle 42 is provided with a hook part 421 that can be locked onto an external shooting device. The buckle 42 is integrally formed with the rotating connection part 41, which can increase the overall structural strength of the locking and positioning structure 40, enabling it to withstand the long-term gravity load of the external shooting device (such as an SLR camera or action camera) and the impact force during the locking process. The hook part 421 makes the locking and positioning structure 40 more precise and stable in its connection with the external shooting device. For example, for a standard slot at the bottom of a shooting device such as a camera, the hook part 421 can be adapted to the slot and locked in place under the elastic force of the torsion spring 20, effectively preventing the shooting device from loosening or falling off during movement or rotation.

[0029] Further reference Figure 2 An anti-slip part 422 is provided on the outer side of the end of the buckle 42 away from the hook part 421. When it is necessary to install or remove external shooting equipment from the adapter, the operator needs to press the buckle 42 to rotate the locking and positioning structure 40. At this time, the anti-slip part 422 can effectively increase the friction between the operator's fingers and the buckle 42, making the pressing action more effortless and precise. This anti-slip effect is more obvious, especially when the hands are sweaty, wet, or wearing gloves.

[0030] Optionally, the anti-slip part 422 can be a striped protrusion on the outer side of the buckle 42, or multiple dot-shaped protrusions, or other structures, all of which can achieve the anti-slip effect.

[0031] refer to Figure 2 , Figures 5 to 7In an optional embodiment of this application, the adapter body 10 includes a first housing 11 and a second housing 12 that can be fitted and installed with the first housing 11. The first housing 11 is provided with a first mounting groove 11a and a second mounting groove 11b. One end of the rotating shaft 30 is disposed in the first mounting groove 11a and the other end is disposed in the second mounting groove 11b. The second housing 12 is provided with a first cover portion 12a and a second cover portion 12b on the side facing the first housing 11. After the first housing 11 and the second housing 12 are fitted and installed, the first cover portion 12a covers the opening of the first mounting groove 11a and the second cover portion 12b covers the opening of the second mounting groove 11b.

[0032] Specifically, the first mounting groove 11a and the second mounting groove 11b on the first housing 11 provide precise mounting references for both ends of the rotating shaft 30. After the rotating shaft 30 passes through the rotating connection part 41 of the engaging positioning structure 40 and the torsion spring 20, the operator only needs to place both ends of the rotating shaft 30 into the first mounting groove 11a and the second mounting groove 11b respectively, and then align the second housing 12 with the first housing 11 to complete the initial positioning of the rotating shaft 30. After the first cover part 12a and the second cover part 12b are aligned, they can respectively and tightly cover the openings of the first mounting groove 11a and the second mounting groove 11b, forming a complete shaft hole together with the corresponding first mounting groove 11a and the second mounting groove 11b, firmly installing the rotating shaft 30 in the preset position, preventing the rotating shaft 30 from detaching from the first mounting groove 11a and the second mounting groove 11b during the operation of the device, and the installation of the engaging positioning structure 40 with the rotating shaft 30 and the torsion spring 20 is very convenient. When it is necessary to replace the torsion spring 20 or the shaft 30, simply disconnect the connection between the first housing 11 and the second housing 12. After the first cover 12a and the second cover 12b are separated from the corresponding mounting slots, the shaft 30 can be directly removed from the first mounting slot 11a and the second mounting slot 11b without disassembling other related components, making assembly and maintenance quick and easy.

[0033] Optionally, the first mounting groove 11a and the second mounting groove 11b can be adapted to the rotating shaft 30. For example, if the rotating shaft 30 is cylindrical, the first mounting groove 11a and the second mounting groove 11b can be set as semi-circular grooves.

[0034] refer to Figure 2 and Figure 5 In an optional embodiment of this application, the mounting structure 50 includes a first clamping arm 51 and a second clamping arm 52 rotatably disposed on the first housing 11 and located outside the second housing 12. The first clamping arm 51 is provided with a first through hole 51a, and the second clamping arm 52 is provided with a second through hole 52a. When the first clamping arm 51 and the second clamping arm 52 rotate to a preset angle, the first through hole 51a and the second through hole 52a are coaxial.

[0035] Specifically, when the first clamping arm 51 and the second clamping arm 52 rotate to a preset angle and the first through hole 51a and the second through hole 52a are coaxial, a rigid lock can be achieved by fasteners such as bolts and screws passing through the two through holes. This locking method can tightly fix the adapter to the support equipment, preventing loosening of the connection due to vibration or shaking during shooting. Alternatively, for support equipment with ear plates, the ear plates can be clamped between the two clamping arms. Screws can be passed through the ear plate holes and the first through hole 51a on the first clamping arm 51 and the second through hole 52a on the second clamping arm 52, achieving a "sandwich" type fixation. The angle between the ear plates and the first clamping arm 51 and the second clamping arm 52 can be adjusted by unlocking the screws, thereby adjusting the angle of the shooting equipment relative to the support equipment, which has high practicality. In addition, the rotating first clamping arm 51 and the second clamping arm 52 with coaxial through holes also makes the installation process of the adapter on the external support equipment more efficient.

[0036] refer to Figure 2 , Figures 5 to 7 In an optional embodiment of this application, a first positioning hole 12c is provided on the area corresponding to the first clamping arm 51 on the second housing 12, and a second positioning hole 12d is provided on the area corresponding to the second clamping arm 52. A third positioning hole 11c corresponding to the first positioning hole 12c and a fourth positioning hole 11d corresponding to the second positioning hole 12d are provided on the first housing 11. The second housing 12 is mounted on the first housing 11 by passing through the first positioning hole 12c and the third positioning hole 11c through the first fixing member 13, and by passing through the second positioning hole 12d and the fourth positioning hole 11d through the second fixing member 14. A first magnetic suction member 511 is provided on the first clamping arm 51, and the first magnetic suction member 511 can magnetically attract each other with the first fixing member 13. A second magnetic suction member 521 is provided on the second clamping arm 52, and the second magnetic suction member 521 can magnetically attract each other with the second fixing member 14.

[0037] Specifically, by having the first fixing member 13 pass through the first positioning hole 12c and the third positioning hole 11c, and the second fixing member 14 pass through the second positioning hole 12d and the fourth positioning hole 11d, the precise alignment and assembly of the second housing 12 and the first housing 11 can be facilitated. This also prevents relative displacement between the second housing 12 and the first housing 11 during use, ensuring the rigidity of the overall structure of the adapter body 10. Simultaneously, the magnetic attraction between the first fixing member 13 and the first magnetic attraction member 511 allows the first clamping arm 51 to be magnetically positioned on the outside of the second housing 12 when not in use. Similarly, the magnetic attraction between the second fixing member 14 and the second magnetic attraction member 521 allows the second clamping arm 52 to be magnetically positioned on the outside of the second housing 12 when not in use. This facilitates the storage of the first and second clamping arms 51 and reduces the overall size of the adapter. Therefore, in this embodiment, the first fixing member 13 and the second fixing member 14 not only serve to install and fix the first housing 11 and the second housing 12, but also cooperate with the first magnetic suction member 511 and the second magnetic suction member 521 to accommodate the first clamping arm 51 and the second clamping arm 52.

[0038] Optionally, both the first fixing member 13 and the second fixing member 14 can be screws or bolts, with corresponding positioning holes to achieve the fixed assembly of the first housing 11 and the second housing 12. They can also magnetically attract each other with the first magnetic member 511 and the second magnetic member 521, storing the corresponding first clamping arm 51 and the second clamping arm 52 on the outside of the second housing 12. The first magnetic member 511 and the second magnetic member 521 can be made of magnetic materials such as neodymium iron boron (strong magnet), ferrite, samarium cobalt, and alnico, and can magnetically attract each other with the corresponding first fixing member 13 and the second fixing member 14.

[0039] refer to Figure 5 In an optional embodiment of this application, the mounting structure 50 further includes a fixing hole 12e disposed on the second housing 12 and located between the first clamping arm 51 and the second clamping arm 52, and the inner wall of the fixing hole 12e is provided with an internal thread.

[0040] The mounting hole 12e provides an additional connection option for the adapter to connect with the external support equipment. When the external support equipment uses screw connections, such as tripod screws or desktop stand screws, it can be directly connected and fixed to the adapter through screws that match the internal thread of the mounting hole 12e, without relying on the first clamping arm 51 and the second clamping arm 52. Therefore, the adapter with the first clamping arm 51, the second clamping arm 52, and the mounting hole 12e can achieve both clamping installation via the clamping arms and screw installation via the mounting hole 12e, providing high assembly versatility.

[0041] refer to Figure 2In an optional embodiment of this application, the adapter further includes a magnetic suction component 60 disposed in the adapter body 10. The magnetic suction component 60 forms a magnetic adsorption surface on the front side of the adapter body 10 to adsorb and position an external shooting device.

[0042] By setting up the magnetic suction component 60, a dual positioning system is formed with the locking and positioning structure 40 for the external shooting device, ensuring the stability of the external shooting device installed on the front of the adapter body 10. For example, when shooting outdoors, if the external shooting device is subjected to a sudden vibration, the immediate attraction force of the magnetic suction component 60 can prevent the shooting device from bouncing, while the mechanical locking of the locking and positioning structure 40 can maintain the stability of the structure during the continuous vibration, preventing the shooting device from failing to stay in place due to repeated displacement. Therefore, the combination of the magnetic suction component 60 and the locking and positioning structure 40 can further prevent the external shooting device from sliding or falling off.

[0043] Optional, continue to refer to Figure 2 The magnetic attachment assembly 60 includes a third magnetic attachment 61 and a fourth magnetic attachment 62 disposed within the adapter body 10. The third magnetic attachment 61 and the fourth magnetic attachment 62 are spaced apart along the length of the adapter body 10. This allows the third magnetic attachment 61 and the fourth magnetic attachment 62 to form a two-point magnetic attachment layout (rather than a single-point or overlapping arrangement), enabling stable two-point positioning and adsorption between the adapter body 10 and the shooting device, thus improving the stability of the connection between the external shooting device and the adapter. Furthermore, the spaced arrangement of the third magnetic attachment 61 and the fourth magnetic attachment 62 along the length of the adapter body 10 also assists in the directional installation of the external shooting device on the adapter. For example, the distance between the two adsorption areas on the shooting device can be consistent with the distance between the third magnetic attachment 61 and the fourth magnetic attachment 62 on the adapter body 10; stable adsorption is only possible when aligned, preventing reverse installation or tilting.

[0044] This application also provides an embodiment of a shooting system. This utility model embodiment also provides a shooting system including a shooting device and an adapter as described above. The shooting device is provided with a locking structure for engaging the locking and positioning structure 40 of the adapter. This shooting system includes the same structure and beneficial effects as the adapter in the foregoing embodiments. The structure and beneficial effects of the adapter have been described in detail in the foregoing embodiments and will not be repeated here.

[0045] Optionally, the snap-fit ​​structure can be a slot, a snap-fit ​​hole, or other structure that can mate with the snap-fit ​​positioning structure 40 on the adapter.

[0046] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. 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 this utility model.
