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. Summary of the Invention

[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:

[0005] A frame encloses a rabbit cage space for mounting a camera. The frame includes at least one telescopic arm that can extend and retract to change the size of the rabbit cage space. The telescopic arm includes an inner rod and an outer rod, with the inner rod sleeved inside the outer rod and sliding relative to the outer rod along its axial direction.

[0006] A locking sleeve is fitted at the connection point between the inner rod and the outer rod. The first end of the locking sleeve is slidably fitted onto the outer side of the inner rod, and the second end of the locking sleeve is threaded onto the end of the outer rod. At least one of the inner side of the locking sleeve and the outer side of the end of the outer rod is provided with a conical surface, and the extension direction of the conical surface is inclined to the extension direction. When the locking sleeve is tightened, the locking sleeve and the end of the outer rod move relative to each other along the conical surface until they clamp together, thereby increasing the clamping force between the outer rod and the inner rod.

[0007] In one embodiment, the locking sleeve includes a pressure ring and a locking ring. The pressure ring is slidably sleeved on the outside of the inner rod, one end of the locking ring is fixedly sleeved on the outside of the pressure ring, and the other end of the locking ring is threaded onto the end of the outer rod. A first fitting groove is formed by a gap between the inner wall of the end of the outer rod and the outer wall of the inner rod. The conical surface is formed on the outer wall of the pressure ring and / or on the inner wall of the end of the outer rod. Tightening the locking ring drives the pressure ring to move and engage in the first fitting groove. The pressure ring undergoes elastic deformation under the compression of the conical surface and grips the inner rod.

[0008] In one embodiment, the sidewall of the clamping ring has a slit extending axially to the edge. When the clamping ring moves and engages in the first fitting groove, the width of the slit decreases, the radial dimension of the clamping ring decreases, and the clamping ring grips the inner rod.

[0009] In one embodiment, the clamping ring is circumferentially provided with a plurality of first notches and a plurality of second notches. The first notches extend axially from the inner side of the clamping ring to one end edge of the clamping ring, and the second notches extend axially from the inner side of the clamping ring to the other end edge of the clamping ring. The first notches and second notches are arranged alternately and at intervals along the circumference of the clamping ring. When the clamping ring moves and engages in the first fitting groove, the width of the first notches and the second notches decreases, the radial dimension of the clamping ring decreases, and the clamping ring grips the inner rod.

[0010] In one embodiment, one of the inner sidewall of the locking ring and the outer sidewall of the pressing ring is provided with an annular locking block, and the other is provided with an annular locking groove. The annular locking block is aligned and engaged with the annular locking groove along the radial direction of the telescopic arm to achieve axial positioning of the pressing ring and the locking ring.

[0011] In one embodiment, the outer rod includes a connecting section and a telescopic section that are detachably connected along its axial direction, one end of the connecting section being fitted inside the telescopic section and the other end of the connecting section being fitted outside the inner rod; the locking ring is threaded onto the outside of the connecting section.

[0012] In one embodiment, one end of the inner rod is connected to a large end, which is fitted inside the telescopic end. The outer diameter of the large end is larger than the inner diameter of the connecting section, and the inner diameter of the connecting section is smaller than the inner diameter of the telescopic section. When the telescopic arm is extended to its maximum size, the large end moves along the telescopic direction to abut against the inner end face of the connecting section and the telescopic section.

[0013] In one embodiment, the connecting segment includes a first segment and a second segment connected axially, the outer diameter of the first segment being larger than the outer diameter of the second segment, the second segment being fitted inside the telescopic segment; the outer diameter of the first segment being larger than the inner diameter of the telescopic segment, and the end of the first segment away from the clamping ring abutting against the end face of the telescopic segment.

[0014] In one embodiment, the outer rod includes a detachable connecting section and a telescopic section along its axial direction. The connecting section is made of an elastic material. A second fitting groove is formed by a gap between the inner wall of the first end of the locking sleeve and the outer wall of the inner rod. The conical surface is formed on the inner wall of the first end of the locking sleeve and / or on the outer wall of the connecting section. The second end of the locking sleeve is threaded onto the outer side of the telescopic section. Tightening the locking sleeve drives the connecting section to move and engage in the second fitting groove. The connecting section undergoes elastic deformation under the pressure of the conical surface and grips the inner rod.

[0015] In one embodiment, the frame includes at least a first side frame and a second side frame that are perpendicularly connected, and both the first side frame and the second side frame include the telescopic arm, so that the horizontal and vertical dimensions of the rabbit cage space can be adjusted.

[0016] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects:

[0017] This invention provides an adjustable-size camera cage. Users can easily adjust the length of the telescopic arm within the frame by rotating the locking sleeve, thus adjusting the cage's size to accommodate cameras of various sizes. Furthermore, the telescopic arm allows the camera cage to retract to its minimum size when not in use, resulting in a compact design 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

[0028] 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.

[0029] 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.

[0030] 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.

[0031] Reference Figure 1-5 This application provides an adjustable-size camera cage 1, including a frame 10 and a locking sleeve 20 disposed on the frame 10. The frame 10 encloses a cage space 101 for mounting a camera. The frame 10 includes at least one telescopic arm 102, which can extend and retract to change the size of the cage space 101. The telescopic arm 102 includes an inner rod 11 and an outer rod 12. The inner rod 11 is sleeved on the inner side of the outer rod 12 and slides axially relative to the outer rod 12. The locking sleeve 20 is sleeved at the connection position between the inner rod 11 and the outer rod 12. The first end 201 of the locking sleeve 20 is slidably sleeved on the outer side of the inner rod 11, and the second end 202 of the locking sleeve 20 is threaded onto the end of the outer rod 12. At least one of the inner side of the first end 201 and the outer side of the end of the outer rod 12 of the locking sleeve 20 has a conical surface 30, the extension direction of which is inclined to the extension direction. Tighten the locking sleeve 20. The locking sleeve 20 and the outer rod 12 move relative to each other along the conical surface 30 until they clamp together, thereby increasing the clamping force between the outer rod 12 and the inner rod 11, preventing relative sliding between the outer rod 12 and the inner rod 11, and fixing the length of the telescopic arm 102. This achieves the purpose of adjusting the size of the rabbit cage space 101, adapting it to the installation and use of more cameras of different sizes. Here, the camera is used as a shooting device, but it can also be other electronic devices with photography functions, such as mobile phones, tablets, instant cameras, camcorders, etc.

[0032] This invention provides an adjustable-size camera cage 1. Users can easily adjust the length of the telescopic arm 102 in the frame 10 by rotating the locking sleeve 20, thereby adjusting the size of the cage space 101 to accommodate cameras of various sizes. Furthermore, the telescopic arm 102 allows the camera cage 1 to retract 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 features simple and quick size adjustment, high adaptability, and can meet a wider range of user needs.

[0033] Optionally, in conjunction with reference Figure 3-5In one embodiment, the locking sleeve 20 includes a pressure ring 21 and a locking ring 22. The pressure ring 21 is slidably sleeved on the outside of the inner rod 11. One end of the locking ring 22 (corresponding to the first end 201 of the locking sleeve 20) is fixedly sleeved on the outside of the pressure ring 21, and the other end of the locking ring 22 (corresponding to the second end 202 of the locking sleeve 20) is threaded onto the end of the outer rod 12. A gap exists between the inner wall of the end of the outer rod 12 and the outer wall of the inner rod 11 to form a first fitting groove 13. A conical surface 30 is formed on the outer wall of the pressure ring 21 and / or the conical surface 30 forms the inner wall of the end of the outer rod 12 (at least one of them has a conical surface 30). Tightening the locking ring 22 drives the pressure ring 21 to move and engage with the first fitting groove 13. The pressure ring 21 undergoes elastic deformation under the compression of the conical surface 30 and grips the inner rod 11 to increase the clamping force between the outer rod 12 and the inner rod 11. Here, the clamping ring 21 can be made of elastic plastic or elastic rubber. There are two conical surfaces 30, located at the contact points of the outer wall of the clamping ring 21 and the inner wall of the end of the outer rod 12, respectively. The two conical surfaces 30 have the same inclination angle. When the clamping ring 21 moves and engages with the first fitting groove 13, the two conical surfaces 30 fit tightly together, further increasing the relative sliding damping between the inner rod 11 and the outer rod 12. Of course, in other embodiments, there are two conical surfaces 30 with different inclination angles; optionally, there can be only one conical surface 30.

[0034] Preferably, in one embodiment, in conjunction with reference to Figure 5 and Figure 6 The side wall of the clamping ring 21 has an axially extending notch 211. When the clamping ring 21 moves and engages in the first fitting groove 13, the width of the notch 211 decreases, the radial dimension of the clamping ring 21 decreases, and the clamping ring 21 grips the inner rod 11 to increase the clamping force between the outer rod 12 and the inner rod 11. Here, the notch 211 provides deformation space for the clamping ring 21 on the one hand; on the other hand, the notch 211 can be pried open and widened under the action of external force, and then the clamping ring 21 can be engaged and sleeved on the outside of the inner rod 11 radially along the notch 211, or directly disengaged from the inner rod 11 radially, which facilitates the assembly or replacement of the clamping ring 21.

[0035] Alternatively, in one embodiment, in conjunction with reference to Figure 5 and Figure 6The clamping ring 21 is provided with a plurality of first notches 212 and second notches 213 spaced apart in the circumference. The first notches 212 extend axially from the inner side of the clamping ring 21 to one end edge of the clamping ring 21, and the second notches 213 extend axially from the inner side of the clamping ring 21 to the other end edge of the clamping ring 21. The first notches 212 and second notches 213 are arranged alternately in the circumference of the clamping ring 21. When the clamping ring 21 moves and is inserted into the first fitting groove 13, the width of the first notches 212 and second notches 213 becomes smaller, the radial dimension of the clamping ring 21 decreases, and the clamping ring 21 hugs the inner rod 11 to increase the clamping force between the outer rod 12 and the inner rod 11.

[0036] It should be noted that the gap 211, the first gap 212, and the second gap 213 are all for the purpose of enabling the clamping ring 21 to undergo elastic deformation and hold the inner rod 11. In specific embodiments, at least one of these structures or multiple combinations thereof can be provided. Therefore, in this application, any means that enable the clamping ring 21 to undergo elastic deformation and change its radial dimension should be protected.

[0037] Alternatively, in one embodiment, in conjunction with reference to Figure 3 and Figure 5 In one embodiment, at least one of the inner wall of the locking ring 22 and the outer wall of the pressure ring 21 is provided with an annular locking block 221, and the other is provided with an annular locking groove 214. The annular locking block 221 is radially aligned and engaged with the annular locking groove 214 along the telescopic arm 102 to achieve axial limiting of the pressure ring 21 and the locking ring 22. The pressure ring 21 and the locking ring 22 move synchronously in the axial direction (telescopic direction). Loosening or tightening the threads of the locking ring 22 can drive the pressure ring 21 to reciprocate relative to the inner rod 11 in the telescopic direction. Here, the pressure ring 21 and the locking ring 22 are detachable and can be machined separately, reducing the difficulty of machining the threads on the inner side of the locking ring 22 and facilitating the replacement and assembly of the pressure ring 21 and the locking ring 22. Of course, in other embodiments, the pressure ring 21 and the locking ring 22 can also be integrally formed to achieve synchronous movement of the two. In addition, the annular locking block 221 and the annular locking groove 214 are mating assemblies, and their shapes are not limited. They only need to be aligned and engaged along the radial direction of the telescopic arm 102.

[0038] Optionally, in conjunction with reference Figure 3-5In one embodiment, the outer rod 12 includes a connecting section 121 and a telescopic section 122 that are detachably sleeved along its axial direction. One end of the connecting section 121 is fitted inside the telescopic section 122, and the other end of the connecting section 121 is fitted outside the inner rod 11. A gap exists between the inner sidewall of the connecting section 121 and the outer sidewall of the inner rod 11, forming the first fitting groove 13 described above. The locking ring 22 is threaded onto the outer side of the connecting section 121. Here, the outer side of the connecting section 121 has an external thread 123, and the inner side has a conical surface 30. As a detachable part, this greatly reduces the machining difficulty of the external thread 123 and the conical surface 30. Moreover, if the external thread 123 slips or the conical surface 30 deforms, a new connecting section 121 can be replaced at any time to ensure the telescopic locking function of the entire telescopic arm 102. Of course, in other embodiments, the connecting section 121 and the telescopic section 122 can also be integrally formed, and the external thread 123 of the outer rod 12 can also be processed on the outside of the telescopic section 122, as long as the locking ring 22 can be threaded onto the outside of the outer rod 12.

[0039] Preferably, in one embodiment, in conjunction with reference to Figure 3 Figure 5 One end of the inner rod 11 is connected to a large end 14, which is fitted inside the telescopic section 122. The outer diameter of the large end 14 is larger than the inner diameter of the connecting section 121, while the inner diameter of the connecting section 121 is smaller than the inner diameter of the telescopic section 122. When the telescopic arm 102 extends to its maximum size, the large end 14 moves along the telescopic direction to abut against the inner end face where the connecting section 121 and the telescopic section 122 meet, preventing the inner rod 11 from being overstretched and disengaged from the outer rod 12. The large end 14 serves as an anti-disengagement and limiting device for the inner rod 11. At this time, tightening the locking ring 22 can stably maintain the maximum length of the telescopic arm 102. Of course, in other embodiments, the large end 14 may not be used to prevent disengagement. The user can control the force during the stretching process and then lock the length of the telescopic arm 102 by using the clamping ring 21.

[0040] Preferably, in conjunction with reference Figure 3 and Figure 5In one embodiment, the connecting segment 121 includes a first segment 1211 and a second segment 1212 connected axially. The outer diameter of the first segment 1211 is larger than that of the second segment 1212, and the second segment 1212 is fitted inside the telescopic segment 122. The outer diameter of the first segment 1211 is larger than that of the telescopic segment 122. A locking ring 22 is threaded onto the first end 1211, and the first segment 1211 abuts against the end face of the telescopic segment 122. Here, as shown in the figure, there is a gap between the inner sidewall of the first segment 1211 and the outer sidewall of the inner rod 11 to form the first fitting groove 13 mentioned above. The conical surface 30 is also formed on at least one of the inner sidewall of the first segment 1211 and the outer sidewall of the clamping ring 21. When the user tightens the locking ring 22, the pressure ring 21 moves and engages with the first fitting groove 13. This causes the first segment 1211 and the pressure ring 21 to tend to move relative to each other in the telescopic direction (axial direction) under the pressure of the conical surface 30. The design of the end of the first segment 1211 away from the pressure ring 21 abutting against the end face of the telescopic segment 122 prevents the first segment 1211 from moving and engaging with the inner side of the telescopic segment 122, thus axially limiting the connection segment 121 and the telescopic segment 122, preventing them from moving relative to each other in the telescopic direction, further improving the length locking stability of the telescopic arm 102. In addition, the end face of the second segment 1212 cooperates with the large end 14 to limit and stabilize the maximum length dimension of the telescopic arm 102. Therefore, designing the first segment 1211 and the second segment 1212 with different outer diameters can simultaneously achieve the locking and limiting function of the telescopic arm 102 and the limiting function of the maximum length dimension of the telescopic arm 102, with a simple structure and ingenious design. Of course, in other embodiments, the connecting segment 121 does not need to be designed as a first segment 1211 and a second segment 1212 with different outer diameters. The connecting segment 121 and the telescopic segment 122 can be integrally formed to achieve axial limiting. Alternatively, the connecting segment 121 can be directly axially inserted into the end face of the telescopic segment 122 to achieve axial limiting. Therefore, in this application, any method or means that can achieve axial limiting of the connecting segment 121 and the telescopic segment 122 should be protected.

[0041] Optionally, refer to Figure 1 or Figure 2 In one embodiment, the frame 10 includes at least a first side frame 15 and a second side frame 16 that are perpendicularly connected. Both the first side frame 15 and the second side frame 16 include telescopic arms 102, allowing both the lateral and longitudinal dimensions of the camera cage space 101 to be adjusted. This improves the overall flexibility of the camera cage 1 in terms of size adjustment, enabling it to accommodate cameras of various sizes. The telescopic methods of the first side frame 15 and the second side frame 16 can also differ. One may include a telescopic arm 102, while the other may include a telescopic slide rail or other telescopic structure, which can also achieve adjustment of the lateral and longitudinal dimensions of the camera cage space 101.

[0042] Second Embodiment

[0043] refer to Figure 7 The telescopic locking structure in this embodiment is basically the same as that in the first embodiment, except that in the first embodiment, the inner rod 11 is clamped by the clamping ring 21 to increase the radial clamping force between the inner rod 11 and the outer rod 12 (in combination with...). Figure 4 In this embodiment, the radial clamping force between the outer rod 12 and the inner rod 11 is increased by directly clamping the end of the outer rod 12. The specific implementation is as follows: The outer rod 12 includes a connecting section 121 and a telescopic section 122 that are detachably connected along its axial direction. The connecting section 121 is made of elastic material. A second fitting groove 17 is formed between the inner wall of the first end 201 of the locking sleeve 20 and the outer wall of the inner rod 11. A conical surface 30 is formed on the inner wall of the first end 201 of the locking sleeve 20 and / or the outer wall of the end of the outer rod 12 (at least one of them has a conical surface 30). The second end of the locking sleeve 20 is threaded onto the outer side of the telescopic section 122 (i.e., the external thread 123 is provided on the outer wall of the telescopic section 122). Tightening the locking sleeve 20 drives the connecting section 121 to move and engage in the second fitting groove 17. The connecting section 121 clamps the inner rod 11 under the pressure of the conical surface 30.

[0044] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
