Description

Technical Field

[0001] This utility model relates to the field of photographic accessories technology, and in particular to an adjustable-size camera cage. Background Technology

[0002] As people's demands for camera shooting increase, camera cages have become an essential option for photography enthusiasts. Camera cages can hold the camera and provide expanded functionality and assistance in complex shooting operations. Traditional camera cages fix the camera inside their space. When adjusting the shooting angle, the auxiliary equipment on the cage needs to move along with it, resulting in instability of the auxiliary equipment's center of gravity and inconvenience in operation. Furthermore, traditional camera cages have low compatibility; different sizes of cameras require different sized cages, making switching between them cumbersome. Utility Model Content

[0003] The present invention provides an adjustable-size camera cage to solve the technical problem that traditional camera cages cannot be arbitrarily changed in size to fit cameras of different sizes.

[0004] This utility model discloses an adjustable-size camera cage, comprising: A rectangular frame encloses a rabbit cage space for mounting a camera. The rectangular frame includes a first border, a second border, a third border, and a fourth border connected end to end. All four side frames are equipped with telescopic structures. The first side frame and the third side frame are parallel to each other and can be telescopically extended and retracted to adjust the lateral dimension of the rabbit cage space. The second side frame and the fourth side frame are parallel to each other and can be telescopically extended and retracted to adjust the longitudinal dimension of the rabbit cage space.

[0005] In one embodiment, the telescopic structure of the first frame includes a first fixed segment, a first movable segment, and a first reset member. The first movable segment is slidably connected to the first fixed segment, and the first reset member is disposed between the first fixed segment and the first movable segment. The first reset member accumulates and releases a reset force along the telescopic direction of the first frame, and the reset force causes the second frame and the fourth frame to have a tendency to move closer to each other. The telescopic structure of the second frame includes a second fixed section, a second movable section, and a second reset member. The second movable section is slidably connected to the second fixed section. The second reset member is located between the second fixed section and the second movable section. The second reset member accumulates and releases a reset force along the telescopic direction of the second frame. This reset force causes the first frame and the third frame to have a tendency to move closer to each other.

[0006] In one embodiment, the first fixed section is provided with a first tube groove, the first movable section is slidably connected to the first tube groove, and the first reset member includes a first telescopic spring, which is sleeved on the outside of the first movable section and located inside the first tube groove. And / or, the second fixed section is provided with a second tube groove, the second movable section is slidably connected to the second tube groove, and the second reset member includes a second telescopic spring, which is sleeved on the outside of the second movable section and located inside the second tube groove.

[0007] In one embodiment, the telescopic structure of the first frame includes a first fixed segment, a first movable segment, and a first locking member. The first movable segment is slidably connected to the first fixed segment, and the first locking member is connected between the first fixed segment and the first movable segment. The first locking member provides sliding damping for the relative movement of the first fixed segment and the first movable segment to fix the length dimension of the first frame. The telescopic structure of the second frame includes a second fixed section, a second movable section, and a second locking member. The second movable section is slidably connected to the second fixed section, and the second locking member is connected between the second fixed section and the second movable section. The second locking member provides sliding damping for the relative movement of the second fixed section and the second movable section to fix the length of the second frame.

[0008] In one embodiment, the first locking member includes a first pressing ring and a first locking ring. The first pressing ring is movably sleeved on the outside of the first movable segment along the extension direction of the first movable segment. One end of the first locking ring is fixedly sleeved on the outside of the first pressing ring, and the other end of the first locking ring is threadedly sleeved on the outside of the first fixed segment. Tightening the first locking ring drives the first pressing ring to move axially toward the first fixed segment and engage between the first movable segment and the first fixed segment. The first pressing ring is used to increase the radial pressing force between the first fixed segment and the first movable segment. And / or, the second locking member includes a second clamping ring and a second locking ring. The second clamping ring is movably sleeved on the outside of the second movable segment along the extension direction of the second movable segment. One end of the second locking ring is fixedly sleeved on the outside of the second clamping ring, and the other end of the second locking ring is threadedly sleeved on the outside of the second fixed segment. Tightening the second locking ring drives the second clamping ring to move axially toward the second fixed segment and engage between the second movable segment and the second fixed segment. The second clamping ring is used to increase the radial clamping force between the second fixed segment and the second movable segment.

[0009] In one embodiment, the first locking member includes a first set screw, which is threaded through the first fixed section along the radial direction of the first frame; when the first set screw is tightened, the end of the first set screw moves to abut against the outer wall surface of the first movable section, and the first set screw is used to increase the radial clamping force between the first fixed section and the first movable section. And / or, the second locking member includes a second set screw, which is threaded radially through the second fixed section along the second frame; when the second set screw is tightened, the end of the second set screw moves to abut against the outer wall surface of the second movable section, and the second set screw is used to increase the radial clamping force between the second fixed section and the second movable section.

[0010] In one embodiment, the telescopic structure of the first frame includes a first fixed section, a first movable section, and a first reset member. The first movable section is slidably connected to the first fixed section, and the first reset member is disposed between the first fixed section and the first movable section. The first reset member accumulates and releases reset force along the telescopic direction of the first frame to adjust the lateral dimension of the rabbit cage space. The telescopic structure of the second frame includes a second fixed section, a second movable section, and a second locking member. The second movable section is slidably connected to the second fixed section, and the second locking member is connected between the second fixed section and the second movable section. The second locking member provides sliding damping for the relative movement of the second fixed section and the second movable section to fix the length dimension of the second frame, thereby fixing the longitudinal dimension of the rabbit cage space.

[0011] In one embodiment, a blocking portion is provided on one end face of the rectangular frame along the depth direction of the rabbit cage space. The blocking portion includes a first blocking portion and a second blocking portion provided on two opposite sides of the rectangular frame. The first blocking portion and the second blocking portion are used to clamp the camera along the horizontal or vertical direction of the rabbit cage space.

[0012] In one embodiment, the number of the first blocking parts is at least two and they are spaced apart on both sides of the telescopic structure of the corresponding frame, and the two first blocking parts move closer or further apart as the corresponding frame extends or retracts; and / or, the number of the second blocking parts is at least two and they are spaced apart on both sides of the telescopic structure of the corresponding frame, and the two second blocking parts move closer or further apart as the corresponding frame extends or retracts.

[0015] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects: This utility model provides an adjustable-size camera cage. Because all four sides of the camera cage can extend and retract to change their length, the size of the cage space can be easily adjusted. Users can first adjust the cage space to its largest size using the telescopic structure of the rectangular frame's sides, place the camera inside, and then the four sides retract under external force to fit the camera's outer shell and match its contours. Therefore, the size of the camera cage can be freely switched to match cameras of different sizes. Secondly, the camera cage can retract to its smallest size when not in use, resulting in a compact size that is easy to carry and store. This camera cage offers simple and quick size adjustment, high adaptability, and can meet a wider range of user needs. Attached Figure Description

[0019] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0021] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "setup," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] Reference Figure 1 and Figure 2This application discloses an adjustable-size camera cage 1, including a rectangular frame 101. The rectangular frame 101 encloses a cage space 102 for mounting the camera. The rectangular frame 101 includes a first side 10, a second side 20, a third side 30, and a fourth side 40 connected end-to-end. Each of the four side frames is equipped with a telescopic structure 103. The first side 10 and the third side 30 are parallel and can be simultaneously extended and retracted to the same length to adjust the lateral size of the cage space 102 (rectangular frame 101). The second side 20 and the fourth side 40 are parallel and can be simultaneously extended and retracted to the same length to adjust the longitudinal size of the cage space 102 (rectangular frame 101). It should be noted that the terms "first," "second," "third," and "fourth" refer to the relative order in which the four side frames are connected, and do not specifically refer to any particular side frame; "lateral" and "longitudinal" represent two perpendicularly intersecting directions and are not specifically designated; the camera, as a shooting device, can also be other electronic devices with photographic functions, such as mobile phones, tablets, instant cameras, camcorders, etc.

[0023] This invention provides an adjustable-size camera cage 1. Since all four sides of the camera cage 1 can extend and retract to change their length, the size of the cage space 102 can be easily adjusted. Users can first adjust the cage space 102 to its maximum size using the extension and retraction of the rectangular frame 101, place the camera in the largest possible cage space 102, and then, under external force, shorten the four sides to fit the camera's outer shell and match its outer contour. Therefore, the size of the cage space 102 of this camera cage 1 can be freely switched to match cameras of different sizes. Secondly, the camera cage 1 can be retracted to its minimum size when not in use, resulting in a compact size that is easy to carry and store. The camera cage 1 of this application offers simple and quick size adjustment, high adaptability, and can meet a wider range of user needs.

[0024] Here, the telescopic structure 103 of the frame can be a telescopic slide rail, telescopic rod, or other structure that can change its length. After the frame extends or retracts, the extension length can be automatically fixed, a locking structure can be set to fix the extension length, or external force can be used to fix the extension length. The extension and retraction method of the frame can be manual or mechanically automatic. Based on the extension and retraction of the four frame lengths and the fixing method, the following three implementation scenarios can be roughly divided: Example 1: The telescopic structure 103 of the two adjacent sides of the rectangular frame 101 has a reset component, which enables the rabbit cage space 102 to automatically shrink in the horizontal and vertical directions.

[0025] Optionally, in conjunction with reference Figure 3 and Figure 4In one embodiment, the telescopic structure 103 of the first frame 10 includes a first fixed section 11, a first movable section 12, and a first reset member 13. The first movable section 12 is slidably connected to the first fixed section 11, and the two move relative to each other to change the length of the first frame 10. The first reset member 13 is disposed between the first fixed section 11 and the second movable section 22. The first reset member 13 accumulates or releases reset force along the telescopic direction (axial or length direction) of the first frame 10, combined with... Figure 1 and Figure 2 This resetting force causes the second frame 20 and the fourth frame 40 to tend to move closer together. Similarly, the telescopic structure 103 of the second frame 20 includes a second fixed section 21, a second movable section 22, and a second resetting member (not shown). The second movable section 22 is slidably connected to the second fixed section 21, and the two move relative to each other to change the length of the second frame 20. The second resetting member is located between the second fixed section 21 and the second movable section 22. The second resetting member accumulates or releases resetting force along the telescopic direction (axial or length direction) of the second frame 20, which causes the first frame 10 and the third frame 30 to tend to move closer together.

[0026] It is understandable that, since both adjacent frame sides can be retracted and reset by the reset mechanism, in this embodiment, the user can first stretch the entire rectangular frame 101 to a larger size, then place it against the camera housing, and release it. Without applying additional force to retract the cage space 102, the four frame sides will automatically retract and press against the camera housing wall under the reset force of the two reset mechanisms. Here, the telescopic structures 103 of the third frame side 30 and the fourth frame side 40 can be the same or different: the third frame side 30 can adopt the same telescopic structure 103 as the first frame side 10, with the same reset mechanism to synchronously increase the longitudinal reset retraction force; the third frame side 30 can also adopt a simple telescopic rod or telescopic rail or other telescopic structure 103, without a reset mechanism, and the first reset mechanism 13 can also drive the third frame side to retract. The fourth frame side 40 can adopt the same telescopic structure 103 as the second frame side 20, with the same reset mechanism to synchronously increase the lateral reset retraction force; the fourth frame side 40 can also adopt a simple telescopic rod or telescopic rail or other telescopic structure 103, without a reset mechanism, and the second reset mechanism can also drive the fourth frame side to retract.

[0027] Further, refer to Figure 3In one embodiment, the first fixed segment 11 is provided with a first groove 111, the first movable segment 12 is slidably connected to the first groove 111, and the first reset member 13 includes a first telescopic spring 131, which is sleeved on the outside of the first movable segment 12 and located inside the first groove 111. When the second frame 20 has the same telescopic structure 103 as the first frame 10, the second fixed segment 21 is provided with a second groove (not shown), the second movable segment 22 is slidably connected to the second groove, and the second reset member includes a second telescopic spring, which is sleeved on the outside of the second movable segment 22. It should be noted that the first telescopic spring 131 and the second telescopic spring are only means of implementing the reset member. It can be understood that the means of implementing the first reset member 13 and the second reset member can be the same or different. The first reset member 13 may include a magnetic suction element, an elastic sleeve, or other structural components that can accumulate or release linear reset force; or, the second reset member may include a magnetic suction element, an elastic sleeve, or other structural components that can accumulate or release linear reset force.

[0028] Example 2: The telescopic structure 103 of the two adjacent sides of the rectangular frame 101 is equipped with locking parts, so that the horizontal and vertical dimensions of the rabbit cage space 102 are fixed by the locking parts.

[0029] Optionally, in one embodiment, the telescopic structure of the first frame 10 includes a first fixed segment 11, a first movable segment 12, and a first locking member (not shown). The first movable segment 12 is slidably connected to the first fixed segment 11, and the first locking member is connected between the first fixed segment 11 and the first movable segment 12. The first locking member provides sliding damping for the relative movement of the first fixed segment 11 and the first movable segment 12 to fix the size of the first frame 10. Similarly, refer to... Figure 2 The second frame 20 includes a second fixed section 21, a second movable section 22, and a second locking member 23. The second movable section 22 is slidably connected to the second fixed section 21, and the second locking member 23 is connected between the second fixed section 21 and the second movable section 22. The second locking member 23 provides sliding damping for the relative movement of the second fixed section 21 and the second movable section 22 to fix the length dimension of the second frame 20.

[0030] Understandably, the telescopic structures 103 of the two adjacent frames are equipped with locking mechanisms. The user can first stretch the rectangular frame 101 to its maximum size and place the camera inside the cage space 102. One corner of the camera can rest against the corner where the first frame 10 and the second frame 20 meet. External force is then used to shrink the size of the cage space 102 until all four frames of the rectangular frame 101 are against the camera's casing. The user then operates the locking mechanisms to lock the length of the corresponding frames, thus fixing the horizontal and vertical dimensions of the entire cage space 102. Here, the specific implementation method of the telescopic structures 103 of the third frame 30 and the fourth frame 40 is not limited.

[0031] Optionally, in one embodiment, the first locking member and the second locking member 23 lock the length of the corresponding frame by rotational locking. Specifically, the first locking member includes a first pressing ring and a first locking ring. The first pressing ring is movably sleeved on the outside of the first movable segment 12 along the extension direction of the first movable segment 12. One end of the first locking ring is fixedly sleeved on the outside of the first pressing ring, and the first locking ring and the first pressing ring move synchronously along the extension direction. The other end of the first locking ring is threaded onto the outside of the first fixed segment 11. Tightening the first locking ring drives the first pressing ring to move axially towards the first fixed segment 11 and engage between the first movable segment 12 and the first fixed segment 11. The first pressing ring grips the first movable segment 12, increasing the radial clamping force between the first fixed segment 11 and the first movable segment 12. This increases the sliding friction damping between the first fixed segment 11 and the first movable segment 12, preventing relative movement between them and achieving the purpose of fixing the length of the second frame 20. And / or, refer to Figure 5 The second locking element 23 includes a second locking ring 231 and a second pressing ring 232. The second pressing ring 232 is movably sleeved on the outside of the second movable segment 22 along the telescopic direction of the second movable segment 22. One end of the second locking ring 231 is fixedly sleeved on the outside of the second pressing ring 232. The second locking ring 231 and the second pressing ring 232 move synchronously along the telescopic direction. The other end of the second locking ring 231 is threaded onto the outside of the second fixed segment 21. Tightening the second locking ring 231 drives the second pressing ring 232 to move axially closer to the second fixed segment 21 and engage between the second movable segment 22 and the second fixed segment 21. The second pressing ring 232 grips the second movable segment 22, thereby increasing the radial pressing force between the second fixed segment 21 and the second movable segment 22. This increases the sliding friction damping between the second fixed segment 21 and the second movable segment 22, preventing relative movement and achieving the purpose of fixing the length of the second frame 20.

[0032] Optionally, in one embodiment, the first locking member and the second locking member 23 employ a set screw structure (not shown) to lock the length of the corresponding frame. Specifically, the first locking member includes a first set screw, which is threaded through the first fixed section 11 along the radial direction of the first frame 10; tightening the first set screw causes its end to move and abut against the outer wall surface of the first movable section 12, thereby increasing the radial clamping force between the first fixed section 11 and the second fixed section 21. This increases the sliding friction damping between the first fixed section 11 and the first movable section 12, preventing relative movement between them and achieving the purpose of fixing the length of the second frame 20. And / or, the second locking member 23 includes a second set screw, which is threaded through the second fixed section 21 along the radial direction of the second frame 20; tightening the second set screw causes its end to move and abut against the outer wall surface of the second movable section 22, thereby increasing the radial clamping force between the second fixed section 21 and the second movable section 22. This increases the sliding friction damping between the second fixed section 21 and the second movable section 22, preventing relative movement and achieving the purpose of fixing the length of the second frame 20.

[0033] It should be noted that, firstly, the structures of the first locking member and the second locking member 23 can be the same or different, and they can be combined from various different or the same locking structures: the first locking member includes, but is not limited to, locking methods such as the engagement of a locking ring and a pressure ring, a set screw, and a plate buckle; the second locking member 23 includes, but is not limited to, locking methods such as the engagement of a locking ring and a pressure ring, a set screw, and a plate buckle. Furthermore, the specific implementation method of the telescopic structure 103 of the third frame 30 and the fourth frame 40 is not limited.

[0034] Example 3: One of the telescopic structures 103 of the two adjacent frames has a reset component and the other has a locking component, so that one of the horizontal and vertical dimensions of the rabbit cage space 102 can be contracted by the reset component and the other can be fixed in length by the locking component.

The specific implementation and configuration of the first reset member 13 and the second locking member 23 are described in Embodiments 1 and 2 above. Optionally, in another embodiment, the telescopic structure 103 of the first frame 10 includes a first fixed segment 11, a first movable segment 12, and a first locking member; the telescopic structure 103 of the second frame 20 includes a second fixed segment 21, a second movable segment 22, and a second reset member. The specific implementation and configuration of the first locking member and the second reset member are described in Embodiments 1 and 2 above.

[0036] It is understood that in this application, the telescopic structures 103 of the four borders can be the same or different. Through arrangement and combination, the same or different telescopic structures 103 can be combined to form a rectangular frame 101: the first border 10 can use a simple telescopic rod, a telescopic slide rail, a telescopic structure 103 with a reset element, or a telescopic structure 103 with a locking element, etc.; the second border 20 can use a simple telescopic rod, a telescopic slide rail, a telescopic structure 103 with a reset element, or a telescopic structure 103 with a locking element, etc.; the third border 30 can use a simple telescopic rod, a telescopic slide rail, a telescopic structure 103 with a reset element, or a telescopic structure 103 with a locking element, etc.; the fourth border 40 can use a simple telescopic rod, a telescopic slide rail, a telescopic structure 103 with a reset element, or a telescopic structure 103 with a locking element, etc. Furthermore, the reset elements of the different borders can be the same or different, and the locking elements of the different borders can be the same or different. Generally, the rectangular frame 101 adopts a symmetrical structure, that is, the telescopic structures 103 on the two sides are the same, which can greatly improve the installation stability of the entire camera cage 1.

The blocking portion 50 includes a first blocking portion 51 and a second blocking portion 52 respectively disposed on two opposite sides of the rectangular frame 101. The first blocking portion 51 and the second blocking portion 52 are used to clamp the camera along the transverse or longitudinal direction of the cage space 102 to further enhance the installation stability of the cage space 102. Here, the blocking portion 50 increases the contact area between the camera housing and the camera cage 1. In other embodiments, if the depth of the cage space 102 is sufficient, the blocking portion 50 may not be necessary.

The two first blocking portions 51 move closer or further apart as the corresponding frame extends or retracts to accommodate cameras of different sizes. The two first blocking portions 51 and one second blocking portion 52 are not on the same frame, forming a three-point positioning clamp for the camera, improving the camera's installation stability. Similarly, in another embodiment, at least two second blocking portions 52 are spaced apart on both sides of the telescopic structure 103 corresponding to the frame. The two second blocking portions 52 move closer or further apart as the corresponding frame extends or retracts to accommodate cameras of different sizes.

It should be understood that in other embodiments, the number and placement of the first blocking portions 51 or the second blocking portions 52 are not limited.

[0039] Preferably, refer to Figure 1 or Figure 2 In one embodiment, the inner walls of the camera cage space 102 at any two adjacent frame junctions are joined with an arc-shaped chamfer, improving the smoothness of the inner walls of the camera cage space 102, better matching the chamfered contour of the camera shell, and improving the tightness of the installation. And / or, the outer walls of the rectangular frame 101 at any two adjacent frame junctions are joined with an arc-shaped chamfer, greatly improving the smoothness of the entire camera cage 1, reducing the feeling of sharpness, and improving the user's grip comfort. Of course, in other embodiments, the inner or outer sides of adjacent frame junctions may not be joined with an arc-shaped chamfer.
