Description

Technical Field

[0001] This application relates to the field of photographic equipment technology, and in particular to a rotating handle and protective device. Background Technology

[0002] During the shooting process, the camera, mobile phone and other shooting equipment are fixed in the rabbit cage protective frame. In order to make it easier to hold the rabbit cage protective frame, there is usually a handle on one side of the rabbit cage protective frame. The photographer can adjust the overall position of the rabbit cage protective frame and shooting equipment by holding the handle.

[0003] In existing technologies, handles are typically fixed to the rabbit cage's protective frame, making them difficult to disassemble and resulting in an overly large overall device that is inconvenient to store. Existing rabbit cages with detachable handles usually use a snap-fit ​​method where the frame edge and handle body are interlocked. This results in a relatively fixed position between the handle body and the rabbit cage's protective frame, preventing the handle body from rotating. When adjusting the shooting angle, the photographer must adjust their wrist or elbow, leading to inconvenience and a poor user experience. Summary of the Invention

[0004] This application provides a rotating handle and a protective device to solve the problem that the handle of the rabbit cage protective frame in the prior art cannot be disassembled and is inconvenient to adjust the shooting angle.

By rotatably connecting the sleeve portion of the handle assembly to the first and second bases respectively, when adjusting the shooting angle, the handle assembly is rotated around the pivot, causing relative rotation between the handheld portion and the mounting frame. This adjusts the shooting angle of the shooting equipment within the rabbit cage protection frame. Once adjusted, the handheld portion of the handle assembly is in a vertical position, facilitating hand operation by the photographer. The adjustment process is convenient and improves the photographer's comfort. Attached Figure Description

[0057] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0058] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0059] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0060] Please see Figures 1 to 21 The first aspect of this application provides a rotary handle, including: a first base 1, a second base 2, a pivot 3, and a handle assembly 4. The second base 2 and the first base 1 are disposed opposite to each other along a first direction; the first base 1 and the second base 2 are detachably connected by the pivot 3. Figure 6 As shown, the rotating handle can be easily removed from the rabbit cage protection frame when storing the shooting equipment and the rabbit cage protection frame, reducing the overall size of the equipment and facilitating storage; the rotating shaft 3 includes a rotating shaft portion 31, the axis of which is parallel to the first direction; the handle assembly 4 includes a sleeve portion 41, the first end of which is rotatably connected to the first base 1, and the second end of which is rotatably connected to the second base 2. The sleeve portion 41 is arranged around the outer periphery of the rotating shaft portion 31, and the rotation axis of the sleeve portion 41 coincides with the axis of the rotating shaft portion 31. The handle assembly 4 is installed on the mounting bracket 6 of the rabbit cage protection frame through the first base 1 and the second base 2. When in the horizontal shooting state, the hand-held portion 44 in the handle assembly 4 is in the following state. Figure 1 As shown, this design facilitates handheld operation by the photographer. When adjusting the shooting angle, the handle component 4 can be wrapped around... Figure 1The counterclockwise rotation causes relative rotation between the handheld part 44 and the mounting bracket 6, thereby adjusting the shooting angle of the shooting device in the rabbit cage protection frame. Once adjusted, the handheld part 44 is in a vertical position for easy handheld operation by the photographer. Please refer to... Figure 2 By rotating the handle assembly 4 counterclockwise by 90 degrees and keeping the handheld part 44 in a vertical position, the mounting bracket 6 can be changed from a horizontal to a vertical position, thereby adjusting the shooting device from a horizontal shooting position to a vertical shooting position. This is convenient to operate and can improve the shooting comfort of the photographer.

[0061] As a preferred embodiment of this application, the handle assembly 4 further includes a connecting part 45, which is connected between the sleeve part 41 and the hand-held part 44, and the connecting part 45 is arranged perpendicular to the hand-held part 44. The connecting part 45 increases the operating space between the hand-held part 44 and the sleeve part 41, making it easier for the photographer to rotate the sleeve part 41 by using the hand-held part 44.

[0062] It should be noted that if the handle assembly 4 can rotate arbitrarily relative to the first base 1 and the second base 2 during the shooting process, it will affect the normal shooting of the photographer. Therefore, during shooting, at least one of the first base 1, the second base 2 and the mounting bracket 6 needs to be locked to the handle assembly 4 through a locking mechanism.

[0063] In some embodiments of this application, please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 The handle assembly 4 also includes a slider 42 and a first elastic member 43. The slider 42 is slidably disposed inside the sleeve portion 41, and the sliding direction of the slider 42 is a first direction. The slider 42 is sleeved on the outside of the rotating shaft portion 31, and the sleeve portion 41 can drive the slider 42 to rotate around the axis of the rotating shaft portion 31.

[0064] The first base 1 is provided with a drive assembly 5 and a first locking assembly. The drive assembly 5 abuts against the first end of the slider 42, such as... Figure 20 As shown, the first elastic member 43 abuts against the second end of the slider 42; the first locking assembly is located at the first end of the slider 42, and the first locking assembly has a first limiting portion 11 for rotating and limiting the slider 42.

[0065] Please see Figure 7 and Figure 20When the first locking assembly is locked, the first limiting part 11 is embedded in the first end of the sliding member 42. At this time, the sliding member 42 cannot rotate circumferentially, and the sleeve part 41 cannot drive the sliding member 42 to rotate around the rotating shaft part 31. That is, the first base 1, the sliding member 42 and the sleeve part 41 are interlocked. When it is necessary to rotate the handle assembly 4, press the drive assembly 5. The drive assembly 5 pushes the sliding member 42 to slide in the first direction, so that the sliding member 42 moves away from the first limiting part 11 until the first limiting part 11 and the sliding member 42 are completely separated. At this time, rotate the hand grip part 44, and the sleeve part 41 can drive the sliding member 42 to rotate around the rotating shaft part 31, thereby realizing the adjustment of the shooting position of the mounting bracket 6. When the handle assembly 4 is rotated to the predetermined position, the sliding member 42 is reset under the action of the first elastic member 43.

[0066] It should be noted that, in order to simultaneously enable the slider 42 to slide along the first direction inside the sleeve portion 41 and the sleeve portion 41 to drive the slider 42 to rotate around the axis of the rotating shaft portion 31, a corresponding positioning structure needs to be provided between the slider 42 and the sleeve portion 41.

[0067] In some embodiments of this application, please refer to Figures 7 to 10 The sleeve portion 41 has a first positioning portion 411 on its inner circumferential surface and a second positioning portion 421 on its outer circumferential surface. The first positioning portion 411 and the second positioning portion 421 are matched and disposed. The first positioning portion 411 or the second positioning portion 421 is a first sliding groove extending along the first direction, so that the sleeve portion 41 and the sliding member 42 are circumferentially positioned, while the sliding member 42 is not affected in sliding inside the sleeve portion 41.

[0068] In a preferred embodiment of this application, the first positioning part 411 is a first groove extending along a first direction, and the second positioning part 421 is a protruding ridge provided along the first direction, which can slide in the first groove. To ensure that the sleeve part 41 applies force evenly to the sliding member 42, two first grooves are symmetrically provided on the inner circumferential surface of the sleeve part 41, such as... Figure 8 and Figure 9 As shown, two symmetrical protruding ridges are provided on the outer peripheral surface of the slider 42, such as... Figure 7 and Figure 10 As shown.

[0069] In some embodiments of this application, please refer to Figure 6 , Figure 9 , Figure 10The sleeve portion 41 has a first pivot hole 413 at the end away from the sliding member 42 for engaging with the pivot portion 31, and the sliding member 42 has a second pivot hole 425 for engaging with the pivot portion 31. This ensures a stable fit between the handle assembly 4 and the pivot portion 31 and prevents the sleeve portion 41 from shaking when the sliding member 42 slides. At this time, the first elastic member 43 abuts against the end wall of the sleeve portion 41 and the sliding member 42.

[0070] In some embodiments of this application, please refer to Figure 7 and Figure 20 The slider 42 has a first mating part 422. The first limiting part 11 and the first mating part 422 are in a concave-convex fit, so that the slider 42 can rotate circumferentially when the first mating part 422 and the first limiting part 11 are completely separated.

[0071] In some embodiments of this application, please refer to Figure 7 , Figure 10 and Figure 11 The first limiting part 11 or the first mating part 422 is a positioning notch. Multiple positioning notches are arranged sequentially along the circumference of the sliding member 42, which can realize the locking of the handle assembly 4 at multiple rotation positions.

[0072] It should be noted that when the handle assembly 4 has N rotational position states (N≥2), at least N positioning notches need to be set to lock the handle assembly 4 in the N rotational positions. At this time, only one first limiting part 11 or first mating part 422 needs to be set to cooperate with the positioning notch.

[0073] In a preferred embodiment of this application, the handle assembly 4 has only two position states, namely horizontal and vertical. The handle assembly 4 can be adjusted to the horizontal and vertical states by rotating 90 degrees. The first mating part 422 is a positioning notch. Four first mating parts 422 are evenly arranged along the circumference of the slider 42. The four first mating parts 422 are connected to form a cross-shaped recessed structure. The first base 1 is provided with four first limiting parts 11 along the circumference of the slider 42. The four first limiting parts 11 are connected to form a cross-shaped protruding structure. After the slider 42 rotates 90 degrees with the sleeve part 41, the slider 42 slides toward the first base 1 under the action of the first elastic member 43. The first limiting part 11 and the first mating part 422 can be mated again.

[0074] In some embodiments of this application, please refer to Figure 4 , Figure 6 , Figure 7 , Figure 12 , Figure 13 , Figure 15 and Figure 20The drive assembly 5 includes an operating member 51 and a second elastic member 52. The operating member 51 is slidably connected to the first base 1. The sliding direction of the operating member 51 is a first direction. The first base 1 has a through groove 12 at one end near the sliding member 42. The operating member 51 has a drive part 511. The drive part 511 passes through the through groove 12 and abuts against the sliding member 42. When it is necessary to release the circumferential limit between the first base 1 and the sliding member 42, the operating member 51 is pressed, and the drive part 511 pushes the sliding member 42, so that the first mating part 422 is separated from the first limiting part 11, thereby releasing the lock of the first base 1 on the handle assembly 4. The second elastic element 52 abuts between the first base 1 and the operating element 51 to reset the operating element 51. At the same time, it can apply a certain elastic force to the operating element 51. Only when the photographer presses the operating element 51 with a force greater than the elastic force of the second elastic element 52 can the sliding element 42 be pushed to release the lock. This can prevent the photographer from accidentally touching the operating element 51 and causing a misunderstanding of the lock.

[0075] In some embodiments of this application, please refer to Figure 11 , Figure 12 , Figure 13 , Figure 15 and Figure 16 Multiple driving parts 511 are provided along the circumference of the operating member 51. The first base 1 is provided with through grooves 12 in the same number as the driving parts 511. There are notches 513 between adjacent 511. When the pressing part 514 of the operating member 51 is pressed, the driving part 511 can slide along the through groove 12. The outer peripheral surface of the driving part 511 has a protruding third limiting part 512. The first base 1 has a second limiting part 15 for cooperating with the third limiting part 512. After the operating member 51 and the second elastic member 52 are installed into the receiving groove 16 of the first base 1, the third limiting part 512 cooperates with the second limiting part 15 to prevent the operating member 51 from falling out of the receiving groove 16 when it is reset.

[0076] In some embodiments of this application, the operating member 51 has a fourth limiting portion 515 for limiting the second elastic member 52, and the second elastic member 52 is sleeved on the outside of the fourth limiting portion 515 to prevent the second elastic member 52 from twisting inside the operating member 51.

[0077] It should be noted that since the first limiting part 11 and the first mating part 422 are both located inside the sleeve part 41, it is not possible to intuitively perceive whether the first limiting part 11 and the first mating part 422 are completely separated when the operating member 51 is pressed. If the operating member 51 is released rashly at this time, the sliding member 42 will be reset under the action of the first elastic member 43, and the sliding member 42 and the first base 1 will return to the locked state. At this time, rotating the handle assembly 4 may cause interference between the first limiting part 11 and the first mating part 422.

[0078] In another embodiment of this application, please refer to Figure 4 , Figure 7 , Figure 10 , Figure 17 and Figure 20 The second base 2 is provided with a second locking component, which includes an elastic hook 21. The second end of the sliding member 42 has a second mating part 423 for hooking the elastic hook 21. When the sliding member 42 is pushed by the driving component 5, if the elastic hook 21 engages with the second mating part 423, the photographer can hear a clicking sound, which means that the first limiting part 11 and the first mating part 422 have been completely separated. At this time, the operating component 51 is released. Since the sliding member 42 is hooked by the elastic hook 21, the sliding member 42 will not reset under the action of the first elastic member 43, thus achieving the sliding lock of the sliding member 42.

[0079] As some embodiments of this application, please refer to Figure 17 , Figure 18 and Figure 19 The elastic hook 21 includes a hook body 211, a third elastic element 212, and a hinge shaft 213. The hinge shaft 213 is connected to the second base 24. The hook body 211 is hinged to the hinge shaft 213. The third elastic element 212 is connected between the hook body 211 and the second base 41, applying a reset pulling force to the hook body 211. When the second mating part 423 pushes the hook body 211, the hook body 211 rotates around... Figure 19 As the second mating part 423 rotates clockwise, it continues to move toward the hook body 211 until the two engage. The hook body 211 is then pulled back by the third elastic element 212, causing the elastic hook 21 and the second mating part 423 to reach a state where... Figure 20 The state shown.

[0080] In some embodiments of this application, the engaging contact surface between the hook body 211 of the elastic hook 21 and the second mating part 423 is perpendicular to the first direction. Please refer to [link / reference]. Figure 20 When the slider 42 needs to rotate around the circumference, the elastic hook 21 will not limit the slider 42.

[0081] In some embodiments of this application, after the first mating part 422 is completely separated from the first limiting part 11, the elastic hook 21 and the second mating part 423 first contact each other through the relatively arranged inclined surfaces. The inclined surface of the elastic hook 21 will push the second mating part 423, causing the slider 42 to rotate at a certain angle. At this time, the first limiting part 11 and the first mating part 422, which are separated from each other, will be misaligned in the circumferential direction of the slider 42. During the rotation of the handle assembly 4, after the second mating part 423 is disengaged from the elastic hook 21, since the initially paired first limiting part 11 and the first mating part 422 have already been misaligned in the circumferential direction, the first elastic member 43 cannot make the slider 42 slide toward the first base 1. It can only lock again when the first mating part 422 rotates to the next first limiting part 11.

[0082] As a preferred embodiment of this application, please refer to Figure 4 , Figure 9 and Figure 17 Two elastic hooks 21, designated as first elastic hook 21a and second elastic hook 21b, are provided on the second base 2. The first elastic hook 21a and second elastic hook 21b are centrally symmetrically arranged about the axis of the rotating shaft 31. Two corresponding second mating parts 423 are provided on the sliding member 42 to achieve uniform engagement with the elastic hooks 21 on the second base 2. Two arc-shaped clearance grooves 414 are provided on the end wall of the sleeve portion 41 to prevent interference between the sleeve portion 41 and the elastic hooks 21 when the sleeve portion 41 rotates.

[0083] The second aspect of this application provides a protection device, such as... Figure 1 and Figure 2 As shown, the rotary handle described in any of the above embodiments also includes a mounting bracket 6, which is clamped between the first base 1 and the second base 2, enabling a detachable connection between the rotary handle and the protective device.

[0084] In some embodiments of this application, the protective device is a rabbit cage protective frame for devices such as mobile phones and cameras, and the mounting bracket 6 is part of the rabbit cage protective frame. By detachably installing the rotating handle on the rabbit cage protective frame, the shooting status and shooting angle of the shooting device can be easily adjusted.

[0085] In some embodiments of this application, the mounting bracket 6 is provided with clamping grooves 63 on both sides, the bottom of the first base 1 is provided with a first claw 13, and the bottom of the second base 2 is provided with a second claw 22. The first claw 13 and the second claw 22 are both matched with the clamping grooves 63. The rotating handle can be slid into one end of the mounting bracket 6, or the first base 1 and the second base 2 can be installed on the mounting bracket 6 by disassembling the rotating shaft 3.

[0086] In some embodiments of this application, please refer to Figure 6 , Figure 11 , Figure 14 and Figure 17 To facilitate the connection between the first base 1, the second base 2, and the rotating shaft 3, the first end of the rotating shaft 3 has a threaded portion 32, and the second end of the rotating shaft 3 has a limiting boss portion 33. The limiting boss portion 33 is provided with a hexagonal groove or a cross groove for cooperating with the installation tool. One of the first base 1 and the second base 2 is threadedly connected to the threaded portion 32, and the other of the first base 1 and the second base 2 is rotatably connected to the limiting boss portion 33.

[0087] Since the drive assembly 5 is installed on the first base 1, it is not convenient to cooperate with the installation tool. As a preferred embodiment of this application, a connecting hole 14 is provided on the first base 1. The connecting hole 14 has an internal thread and can be used to connect with the threaded part 32 of the rotating shaft 3. A first mounting hole 23 is provided on the second base 2. The first mounting hole 23 is a countersunk hole, which is convenient to cooperate with the limiting boss part 33.

[0088] When installing the rotating handle, loosen the threaded connection between the rotating shaft 3 and the first base 1, place the first claw 13 and the second claw 22 on both sides of the mounting bracket 6, and then tighten the rotating shaft 3 so that the first claw 13 and the second claw 22 are clamped in the clamping groove 63.

When the operating member 51 is not pressed, the third mating part 424 is located in the limiting groove 61. At this time, even if the first limiting part 11 is not set, the sliding member 42 cannot rotate circumferentially due to the obstruction of the limiting groove 61. When the operating member 51 is pressed, the third mating part 424 moves synchronously with the sliding member 42. When the sliding member 42 slides, the free end of the third mating part 424 slides in the third slide groove 412. At the same time, the free end of the third mating part 424 slides from the limiting groove 61 into the second slide groove 62. The lock between the third mating part 424 and the mounting bracket 6 is released. The photographer can see directly that the sliding member 42 has been released from the lock. When the handle assembly 4 is turned, the free end of the third mating part 424 can rotate in the second slide groove 62.

[0090] In some embodiments of this application, in order to avoid interference between the sleeve portion 41 and the sliding member 42 during assembly, the third mating portion 424 is detachably provided on the outer peripheral surface of the sliding member 42. The outer peripheral surface of the sliding member 42 is provided with a plurality of second mounting holes 426 for mounting the third mating portion 424. After the sliding member 42 is inserted into the sleeve portion 41, the third mating portion 424 is then installed from the third sliding groove 412 of the sleeve portion 41.

[0091] As a preferred embodiment of this application, please refer to Figure 3 , Figure 5 , Figure 6 , Figure 7 Two third mating parts 424, referred to as third mating part A424a and third mating part B424b, are provided on the outer peripheral surface of the sliding member 42 to realize the locking between the handle assembly 4 and the mounting bracket 6 when in the horizontal and vertical positions.

[0092] In some embodiments of this application, please refer to Figures 1 to 21 The installation and operation process of the above-mentioned protection device is as follows:

[0093] Step 1: Assemble the various parts of the rotating handle. Connect the first base 1, handle assembly 4 and second base 2 together through the rotating shaft 3. At this time, the connecting hole 14 between the rotating shaft 3 and the first base 1 is connected but not tightened.

[0094] Step 2: Place the first base 1 and the second base 2 on both sides of the mounting frame 6, so that the third mating part B424b is located in the limiting groove 61 of the mounting frame 6, and tighten the rotating shaft 3 so that the first base 1 and the second base 2 are clamped on the clamping groove 63.

[0095] Step 3: When switching from horizontal to vertical shooting mode, press the pressing part 514 of the operating member 51. The third mating parts A424a and B424b slide with the sliding member 42. The third mating part B424b slides into the second sliding groove 62, releasing the locking of the limiting groove 61 to the third mating part B424b. The first mating part 422 separates from the first limiting part 11, releasing the locking of the first base 1 to the sliding member 42. Continue pressing the operating member 51 until the second mating part 423 engages with the elastic hook 21, fixing the position of the sliding member 42 in the first direction.

[0096] Step 4: Rotate the handheld part 44 to make the sleeve part 41 drive the sliding part 42 to rotate. After rotating 90 degrees, the first mating part 422 aligns with the first limiting part 11 at the next rotation position. Under the action of the first elastic part 43, the sliding part 42 slides toward the first base 1, realizing the locking of the sliding part 42 by the first base 1. At the same time, the third mating part A424a enters the limiting groove 61, realizing the locking of the handle assembly 4 by the mounting bracket 6, and finally realizing the conversion of the shooting state and the locking and fixing of the rotating handle.
