[0029] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0030] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in a sequence in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0031] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0032] Underwater photography equipment is usually installed in a waterproof housing. For easy transportation, a handle is usually set on the top of the waterproof housing. The handle is usually fixed with screws or other methods. Special tools are required for installation and removal, which is cumbersome. Some photography equipment uses lenses of different types or lengths, which causes the center of the entire equipment to change. When the handle is grabbed for transportation, it is easy for the front to touch the ground first due to the front being heavy and the back being light, which may cause the waterproof lens barrel and the optical lens installed inside to be damaged.

[0033] In response to the above-mentioned problems, the present application proposes a quick-release handle for a waterproof shell of photographic equipment. By changing the position of the handle, it can adapt to the use of waterproof shells of different sizes, and then adapt to changes in the center of gravity of the equipment, thereby avoiding or reducing the risk of damaging the waterproof lens barrel and the optical lens disposed therein due to changes in the center of gravity, thereby improving safety of use.

[0034] See also Figure 1-Figure 5 As shown, the quick-release handle for the waterproof housing of a photographic device provided in this embodiment includes: a fixing member 10 , a handle assembly 20 and a locking mechanism 30 .

[0035] The fixing member 10 is used for being fixedly connected to the waterproof housing, and the fixing member 10 is provided with a slide groove 11. A photographing device is installed inside the waterproof housing.

[0036] In one embodiment, a bolt through hole 111 is further provided on the fixing member 10, and correspondingly, a bolt hole is also provided on the top outer wall of the waterproof shell. The fixing member 10 is fixed to the top of the waterproof shell by means of a bolt passing through the bolt through hole 111 and being screwed into the bolt hole.

[0037] The handle assembly 20 includes a handle 21 and a sliding portion 22 that are connected to each other. The sliding portion 22 is slidably disposed in the slide groove 11 to synchronously drive the handle 21 to slide along the slide groove 11 .

[0038] In this embodiment, the operator can carry the waterproof housing containing the photographic equipment by grabbing the handle 21. When the photographic equipment is used with different lens types and lenses of different lengths, the overall center of gravity will change. The position of the sliding part 22 can be changed by cooperating with the sliding part 22 and the sliding groove 11, and then the position of the handle 21 can be changed to adapt to the use of photographic equipment with different lens types or lenses of different lengths, so as to avoid or reduce the risk of damaging the waterproof lens barrel and the optical lens arranged therein due to the change of the center of gravity, thereby improving the safety of use.

[0039] In one embodiment of the present application, the handle assembly 20 also includes a connecting portion 23, which is connected between the handle 21 and the sliding portion 22. Through the setting of the connecting portion 23, the handle 21 can be located above the sliding portion 22 to form an avoidance space for avoiding the locking mechanism 30, thereby facilitating the operation of the locking mechanism 30.

[0040] In this embodiment, the slide groove 11 is a dovetail groove, and the sliding portion 22 is a dovetail block. During assembly, the sliding portion 22 can be inserted into the slide groove 11 through the end of the fixing member 10 .

[0041] In some embodiments, a blocking limiter 13 is further provided at at least one end of the slide groove 11 along the length direction of the slide groove 11 to limit the sliding displacement of the sliding portion 22 along the slide groove 11 and prevent the sliding portion 22 from escaping from the slide groove 11 .

[0042] like Figure 2-Figure 5 As shown, the locking mechanism 30 includes a knob 31, a pressing block 32, a rotating shaft 33 and a locking member 34. The pressing block 32 is movably arranged on the sliding portion 22 and can move in a direction toward or away from the sliding portion 22. When the pressing block 32 moves toward the sliding portion 22, the pressing block 32 can press the fixing member 10, so that the sliding portion 22 is clamped between the pressing block 32 and the fixing member 10 through the cooperation of the pressing block 32 and the fixing member 10. When the sliding portion 22 slides along the slide groove 11 to a suitable position, the sliding portion 22 can be positioned at the suitable position by clamping the pressing block 32 and the fixing member 10. The suitable position is the position where the handle 21 cooperates with the center of gravity of the waterproof housing on which the photographic equipment is installed. At this time, when the equipment is carried by grabbing the handle 21, the entire equipment is not easy to tilt.

[0043] The pressing block 32 is provided with an axial hole 321, the sliding portion 22 is provided with a locking fitting portion 351, the knob 31 is arranged at one end of the rotating shaft 33, and the locking member 34 is arranged at the other end of the rotating shaft 33. The rotating shaft 33 can be movably passed through the axial hole 321, and the knob 31 abuts against the side of the pressing block 32 facing away from the sliding portion 22, and the locking member 34 is connected to the locking fitting portion 351.

[0044] It should be noted that the rotating shaft 33 is movably inserted into the shaft hole 321, so that the rotating shaft 33 can rotate around its own axis in the shaft hole 321, and can also reciprocate in the shaft hole 321 along its own axis, wherein the axis of the rotating shaft 33 and the axis of the shaft hole 321 can be considered coaxial. The matching relationship between the locking member 34 and the locking matching portion 351 can convert the rotational motion of the rotating shaft 33 around the axis of the shaft hole 321 into a linear motion along the axis of the shaft hole 321.

[0045] In a specific embodiment, by rotating the knob 31 in the locking direction, the locking member 34 cooperates with the locking mating portion 351, so that the rotating shaft 33 can convert the rotational motion around its own axis into a linear motion along its axial direction toward the sliding portion 22, so as to synchronously drive the pressing block 32 to move toward the sliding portion 22 through the knob 31, thereby making the pressing block 32 press the fixing member 10, so that the pressing block 32 and the fixing member 10 clamp the sliding portion 22.

[0046] Of course, when disassembly is required, the knob 31 is rotated in the unlocking direction, and the locking member 34 cooperates with the locking fitting portion 351 to enable the rotating shaft 33 to convert the rotational motion around its own axis into a linear motion along its axial direction away from the sliding portion 22. At this time, the clamping force between the pressing block 32 and the fixing member 10 can be released, thereby releasing the sliding portion 22.

[0047] In one embodiment of the present application, in order to facilitate the manufacture and assembly of the product, the locking mechanism 30 provided in the present embodiment further includes a locking block 35, wherein the locking fitting portion 351 is provided on the locking block 35. The sliding portion 22 is also provided with a mounting cavity 221 that runs through the thickness direction thereof, and the locking block 35 is fixedly installed from the bottom of the sliding portion 22 by a first bolt 352, so that when processing the product, the locking block 35 and the sliding portion 22 can be processed separately, and the locking fitting portion 351 can be processed on the locking block 35, so as to reduce the difficulty of product manufacturing.

[0048] In this embodiment, the locking member 34 is protruding from the rotating shaft 33, and the locking fitting portion 351 is a locking hole 353. The hole wall of the locking hole 353 is also provided with a spiral groove (not shown in the figure) along its axial direction, and the locking member 34 protruding from the rotating shaft 33 is inserted into the spiral groove. When the knob 31 is rotated and the rotating shaft 33 is synchronously driven to rotate by the knob 31, the locking member 34 slides along the length direction of the spiral groove, so that the rotating shaft 33 can convert the rotational motion around its own axis into a linear motion along its axis.

[0049] When the sliding part 22 is clamped and positioned by the pressure block 31 and the fixing part 10, and is carried by the handle 21, in order to avoid the knob 31 from rotating due to accidental contact with the knob 31, thereby reducing the clamping force between the pressure block 31 and the fixing part 10 and causing the sliding part 22 to slide along the slide groove 11, the quick-release handle for the waterproof housing of photographic equipment provided in this embodiment also includes a self-locking mechanism 40, which includes a button 41, a limit block 42 and a limit reset elastic member 43. The knob 31 is provided with a button hole 311, and the button 41 can be reciprocatingly slidably penetrated in the button hole 311. The pressure block 32 is provided with a limit hole 322, and the limit block 42 can be reciprocatingly slidably penetrated in the limit hole 322 between the self-locking position and the release position. The limit reset elastic member 43 is arranged between the limit block 42 and the sliding part 22.

[0050] In this embodiment, Figure 5 As shown, the limiting block 42 has a limiting boss 421. In the self-locking position, the limiting reset elastic member 43 keeps the limiting boss 421 exposed from the pressing block 32. The limiting boss 421 can be inserted into the button hole 311 of the knob 31 to lock the knob 31.

[0051] It should be noted that the button 41 can slide back and forth in the button hole 311. When it slides to the highest position, a certain space is reserved in the button hole 311 below the button 41, and the space allows the limit boss 421 to be inserted. Here, when the knob 31 is rotated in the locking direction so that the pressing block 32 and the fixing member 10 clamp the sliding part 22, the knob 31 is rotated just above the limit block 42, and the limit block 42 is inserted into the button hole 311 under the action of the limit reset elastic member 43 to lock the knob 31 to prevent it from rotating due to accidental contact, so as to maintain the clamping force of the pressing block 32 and the fixing member 10 on the sliding part 22.

[0052] In this embodiment, when the knob 31 needs to be unlocked, the button 41 is pressed so that the portion of the limiting boss 42 inserted into the button hole 311 withdraws from the button hole 311 until the surface of the limiting boss 421 is flush with the bottom surface of the knob 31. At this time, the knob 31 can be rotated.

[0053] Of course, since the position of the limit block 42 in the locked state is blocked and it is difficult to observe the position of the limit block 42 after being pressed, the knob 31 can be rotated synchronously during the process of pressing the limit block 42 through the button 41, so that the knob 31 can be rotated when the surface of the limit boss 421 is flush with the bottom surface of the knob 31.

[0054] See also Figure 3-Figure 5 As shown, the locking mechanism 30 also includes a pre-stressed elastic member 36, which is arranged between the knob 31 and the pressure block 32, and is used to maintain a pre-stress between the pressure block 32 and the fixing member 10 when the pressure block 32 presses the fixing member 10, thereby maintaining the tension on the sliding part 22 and preventing the sliding part 22 from sliding along the sliding groove 11 in the locked state.

[0055] In order to enable the pressing block 32 to move toward or away from the sliding portion 22, the locking mechanism 30 in this embodiment also includes a guide member 37, which is connected to the pressing block 32. A guide hole 222 is provided on the sliding portion 22, and the axial direction of the guide hole 222 is a vertical direction. The guide member 37 is slidably arranged in the guide hole 222 to limit the moving direction of the pressing block 32 through the cooperation between the guide member 37 and the guide hole 222. The pressing block 32, the sliding portion 22 and the fixing member 10 are arranged in sequence from top to bottom. Therefore, the guide hole 222 arranged in the vertical direction can ensure that the pressing block 32 moves toward or away from the sliding portion 22.

[0056] In this embodiment, the locking mechanism 30 further includes an unlocking elastic member 38 . The unlocking elastic member 38 is disposed between the pressing block 32 and the sliding portion 22 . The unlocking elastic member 38 is used to move the pressing block 32 in a direction away from the sliding portion 22 .

[0057] It is understandable that, when the pressing block 32 is separated from the fixing member 10 by rotating the knob 31 , the pressing block 32 can move in a direction away from the sliding portion 22 under the elastic action of the unlocking elastic member 38 .

[0058] In one embodiment of the present application, the unlocking elastic member 38 is a spring, and the guide member 37 can be a rod, so the spring can be sleeved on the guide member 37 .

[0059] like Figure 1 As shown, a limiting portion 12 is provided on the fixing member 10, and a limiting matching portion 39 is provided on the pressing block 32. The limiting portion 12 is located on the side of the slide groove 11 along its width direction. The limiting portion 12 and the limiting matching portion 39 cooperate with each other when the pressing block 32 presses the fixing member 10 to limit the sliding of the sliding portion 22 along the length direction of the slide groove 11, and further avoid the sliding portion 22 from sliding along the slide groove 11 in the pressed state, thereby improving the locking effect.

[0060] In this embodiment, the limiting portion 12 is a plurality of slots 121 disposed on the fixing member 10 along the length direction of the slide slot 11 , and the limiting matching portion 39 is a plurality of protrusions 391 disposed on the pressing block 32 , and the plurality of protrusions 391 respectively match with the plurality of slots 121 .

[0061] It should be noted that multiple slots 121 are arranged along the length direction of the slide slot 11, and when the sliding part 22 is moved along the length direction of the slide slot 11, the pressing block 32 moves synchronously with the sliding part 22, so that the same multiple protrusions 291 can be plugged into and matched with different multiple slots 121 to limit the sliding part 22.

[0062] In summary, the quick-release handle for the waterproof housing of photographic equipment provided by the present application can be positioned at the appropriate position by clamping the sliding part with the pressing block and the fixing part when the sliding part slides to the appropriate position along the slide groove, so that the equipment can be carried by the handle. By turning the knob in the locking direction, the locking part and the locking mating part cooperate with each other, so that the rotational motion of the rotating shaft around its own axis can be converted into a linear motion along its axial direction toward the sliding part, so that the pressing block can be driven to move toward the sliding part synchronously through the knob, and then the pressing block presses the fixing part, so that the pressing block and the fixing part clamp the sliding part, so as to prevent the sliding part from being displaced along the slide groove and position the sliding part.

[0063] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
