DETAILED DESCRIPTION

[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] The waterproof shell of a photographic device is usually composed of a front shell, a middle shell and a rear shell, which correspond to the lens of the photographic device, the host of the photographic device and the battery respectively. When it is necessary to use it with different lenses, an extension ring shell needs to be set between the front shell and the middle shell. In the traditional waterproof shell, the operating handle in the connection structure between the front shell, the middle shell and the rear shell turns from the front of the waterproof shell to the side in the operating direction. Therefore, a large area of ​​hollowing features is set on the front of the waterproof shell to facilitate finger manipulation of the handle. When the thickness of the shell side wall where the operating mechanism is located increases, the corresponding shaft length will increase, weakening the strength of the shaft. At the same time, when the extension ring shell is set, the operating direction of the operating handle of this operating mechanism turns from the front to the side, which is not suitable for the connection between the extension ring shell and the middle shell. Moreover, the design of the hollow area on the front also affects the overall appearance of the product.

[0033] In the present application, the extension ring housing needs to be connected to the front housing and the middle housing. Therefore, when the first housing is the extension ring housing, the second housing can be the middle housing, and when the first housing is the front housing, the second housing can be the extension ring housing. In the following embodiments, the first housing can be the extension ring housing or the front housing, and the second housing can be the middle housing or the extension ring housing.

[0034] See also Figure 1-Figure 9 As shown, the waterproof housing of the photographic device provided in this embodiment includes: a first housing 100, a second housing 200 and a plurality of quick lock devices 300, wherein: Figure 8 and Fig. 9 The first shell 100 is the front shell, and the second shell 200 is the extension ring shell. Figure 8 and Fig. 9 Taking the perspective shown as an example, the front shell is located at the front end of the extension ring shell, and a middle shell is also provided at the rear end of the extension ring shell. Of course, in other embodiments, the first shell 100 can also be a middle shell, and the second shell 200 is an extension ring shell. A plurality of quick lock devices 300 are arranged on the first shell 100 and the second shell 200 along the circumferential direction.

[0035] In this embodiment, the first shell 100 is illustrated by taking the front shell as an example, and the second shell 200 is illustrated by taking the extension ring shell as an example. The first shell 100 is a cylindrical structure with one side closed, and the second shell 200 is a cylindrical structure with openings at both ends. The open end of the first shell 100 is docked with the opening at one end of the second shell 200, and is quickly connected through a quick locking device 300.

[0036] like Figure 1-Figure 5As shown, the quick lock device 300 includes an operating mechanism 31 and a locking mechanism 32. The operating mechanism 31 includes a handle 311, a lock pin assembly 312 and a positioning sleeve 313. The interior or inner wall of the first shell 100 is provided with a guide shaft hole (not shown in the figure). The axial direction of the guide shaft hole is parallel to the axial direction of the first shell 100. The positioning sleeve 313 is fixed in the guide shaft hole along the axial direction of the guide shaft hole. The lock pin assembly 312 is rotatably inserted into the positioning sleeve 313. The lock pin assembly 312 can only rotate around the axial direction of the positioning sleeve 313. The handle 311 is connected to one end of the lock pin assembly 312. The first shell 100 is provided with a receiving groove 101 (as shown in the figure) with a notch facing the outside of the first shell 100. Fig. 9 As shown in FIG. 1 , the receiving groove 101 is connected to the through-shaft hole, and the handle 311 is located in the receiving groove 101. The locking mechanism 32 includes a locking member 321, which is arranged inside the second housing 200 and can slide back and forth between a locking position and an unlocking position along the axial direction of the second housing 200. In other words, the locking member 321 can slide back and forth between a locking position and an unlocking position along the axial direction parallel to the second housing 200. The first housing 100 is docked with the second housing 200 so that the locking pin assembly 312 cooperates with the locking member 321.

[0037] In this embodiment, after the first housing 100 and the second housing 200 are docked, the locking pin assembly 312 can be matched with the locking member 321. When the locking member 321 slides to the locking position along the axial direction parallel to the second housing 200, the locking member 321 can be locked and connected with the locking pin assembly 312, and when the locking member 321 slides to the unlocking position along the axial direction parallel to the second housing 200, the locking member 321 can be unlocked from the connection with the locking pin assembly 312.

[0038] In a specific embodiment, the handle 311 is rotated in the locking rotation direction, and the handle 311 synchronously drives the lock pin assembly 312 to rotate, and the lock pin assembly 312 drives the locking member 321 to be in the locking position, so that the lock pin assembly 312 is locked and connected with the locking member 321. The handle 311 is rotated in the unlocking rotation direction, and the handle 311 synchronously drives the lock pin assembly 312 to rotate, and the lock pin assembly 312 drives the locking member 321 to be in the unlocking position, so that the lock pin assembly 312 is unlocked and connected with the locking member 321, thereby realizing the rapid assembly between the first housing 100 and the second housing 200.

[0039] Combination Figure 8 and Fig. 9 As shown, Figure 8It shows that after the handle 311 is rotated, the locking member 321 is driven to the locked position by the locking pin assembly 312. In this state, the locking pin assembly 312 is locked and connected with the locking member 321, and the top of the handle 311 is at least flush with the outer surface of the first shell 100. In this way, the aesthetic appearance of the product surface can be improved. Fig. 9 It shows that after the handle 311 is rotated, the locking member 321 is driven by the locking pin assembly 312 to be in the unlocked position. At this time, part of the handle 311 is rotated to the outside of the receiving groove 101.

[0040] In one embodiment, the handle 311 can be rotated 105° to switch the locking member 321 from the locked position to the unlocked position.

[0041] In this embodiment, the quick-locking device 300 further includes a self-locking mechanism 33 , which is disposed between the receiving slot 101 and the handle 311 , and is used to lock the handle 311 when the locking pin assembly 312 is locked and connected with the locking member 321 .

[0042] like Figure 3 and Figure 4 As shown, the self-locking mechanism 33 includes: a button 331, a self-locking fixing plate 332, a first self-locking reset elastic member 333, a self-locking slider 334, a rolling member 335, a hook portion 336 and a second self-locking reset elastic member 337. The self-locking slider 334 is slidably disposed in the receiving groove 101 and is located below the handle 311. The second self-locking reset elastic member 337 is disposed between the self-locking slider 334 and the groove wall of the receiving groove 101. The self-locking fixing plate 332 is installed on the handle 311 so that the interval between the self-locking fixing plate 332 and the handle 311 forms a hook portion 3321. Figure 2 As shown, the handle 311 is provided with a first guide hole 3111. Figure 3 As shown, a second guide hole 3322 is provided on the self-locking fixing plate 332, the first guide hole 3111 is coaxial with the second guide hole 3322, the button 331 can be movably penetrated in the first guide hole 3111 and the second guide hole 3322, and a slope 3311 is provided on the side of the button 331 facing the self-locking slider 334, a limiting portion 3312 is provided in the area where the button 331 is located between the self-locking fixing plate 332 and the handle 311, the first self-locking reset elastic member 333 is provided between the limiting portion 3312 and the self-locking fixing plate 332, and the rolling member 335 is provided on the self-locking slider 334.

[0043] In this embodiment, when the handle 311 is rotated to make the locking member 321 in the locking position locked with the locking pin assembly 312, the second self-locking reset elastic member 337 can make the self-locking slider 334 slide along the self-locking direction, so that the hook portion 336 hooks the hook portion 3321, and the handle 311 can be connected by the hook portion 336 hooking the hook portion 3321, so as to limit the rotation of the handle 311 and lock the handle 311. When the handle 311 is rotated to make the locking member 321 in the unlocking position unlocked with the locking pin assembly 312, the button 311 is pressed to make the inclined surface 3311 cooperate with the rolling member 335 to guide the self-locking slider 334 to slide along the unlocking direction, so that the hook portion 336 is separated from the hook portion 3321, and the connection between the hook portion 336 and the handle 311 can be unlocked to release the handle 311.

[0044] like Figure 2 As shown, the lock pin assembly 312 includes a rotating shaft 3121 and a locking pin 3122. The rotating shaft 3121 is rotatably inserted into the positioning sleeve 313. The handle 311 is fixed to one end of the rotating shaft 3121. The locking pin 3122 is fixed to the other end of the rotating shaft 3121. The locking pin 3122 cooperates with the locking member 321. Specifically, when the handle 311 is rotated in the locking rotation direction, the locking pin 3122 drives the locking member 321 to be in the locking position for locking connection, and when the handle 311 is rotated in the unlocking rotation direction, the locking pin 3122 drives the locking member 321 to be in the unlocking position for unlocking connection.

[0045] In one embodiment of the present application, a positioning spring 34 is further provided on the rotating shaft 3121 , and the positioning spring 34 can limit the movement of the rotating shaft 3121 along its axial direction to prevent the rotating shaft 3121 from axially moving.

[0046] In this embodiment, a rubber ring sleeve 35 is further provided at one end of the rotating shaft 3121, and an axial hole is also provided in the groove wall of the first shell 100 located at the accommodating groove 101. The rubber ring sleeve 35 is passed through one end of the rotating shaft 3121 and is set in the axial hole to reduce the friction coefficient with the first shell 100 and avoid wear on the surface of the first shell 100.

[0047] A gasket 36 is disposed between the handle 311 and the rubber ring 35 . The gasket 36 can prevent the handle 311 from directly contacting the first housing 100 , thereby reducing wear on the handle 311 .

[0048] See also Figure 2 and Figure 5As shown, the locking mechanism 32 also includes a mounting plate 322, at least two connecting members 323 and at least two locking reset elastic members 324. The mounting plate 322 is provided with at least two first penetration holes 3221, and the locking member 321 is provided with at least two second penetration holes 3211. The at least two first penetration holes 3221 correspond to the at least two second penetration holes 3211 respectively. The at least two connecting members 323 are respectively penetrated in the at least two first penetration holes 3221 and the at least two second penetration holes 3211, and are fixed inside the second shell 200. The at least two locking reset elastic members 324 are located between the mounting plate 322 and the locking member 321, so that the locking member 321 can slide back and forth along the axial direction of the connecting member 323, and can be reset under the action of the locking reset elastic member 324.

[0049] Particularly, the axial direction of the connecting member 323 is the same as the axial direction of the second housing 200 , so that the locking member 321 can slide back and forth along the axial direction of the connecting member 323 under the action of the connecting member 323 .

[0050] In one embodiment of the present application, a connecting hole 3222 is further provided on the mounting plate 322 , and the locking pin 3122 cooperates with the locking member 321 through the connecting hole 3222 .

[0051] Specifically, after the first housing 100 and the second housing 200 are docked, the lock pin 3122 is matched with the locking member 321 through the connecting hole 3222. When the handle 311 is rotated in the locking rotation direction, the handle 311 synchronously drives the lock pin assembly 312 to rotate, and the lock pin 3122 cooperates with the locking member 321 to move to the locking position along the axial direction of the second housing 200, so that the lock pin 3122 is locked and connected with the locking member 321. When the handle 311 is rotated in the unlocking rotation direction, the handle 311 synchronously drives the lock pin assembly 312 to rotate, and the lock pin 3122 cooperates with the locking member 321 to move to the unlocking position along the axial direction of the second housing 200, so that the lock pin 3122 is unlocked and connected with the locking member 321.

[0052] Combination Figure 6 and Figure 7As shown, the locking member 321 is provided with a locking hole 3212 through it, and a spiral groove 3213 is provided from the hole wall of one end of the locking hole 3212 along the axial direction of the locking hole 3212, and the rotating shaft 3121 is penetrated in the locking hole 3212. The handle 311 is rotated along the locking rotation direction to make the lock pin 3122 move along the spiral groove 3213, and the locking member 321 converts the spiral motion of the lock pin 3122 along the spiral groove 3213 into a linear motion moving along the axial direction of the rotating shaft 3121 toward the handle 311, so that the lock pin 3122 is clamped on the locking member 321, and the connection between the lock pin 3122 and the locking member 321 can be locked. The handle 311 is rotated in the unlocking direction to make the locking pin 3122 move along the spiral groove 3213, and the locking member 321 converts the spiral motion of the locking pin 3122 along the spiral groove 3213 into a linear motion along the axial direction of the rotating shaft 3121 in the direction away from the handle 311, so that the locking pin 3122 is disengaged from the locking member 321, thereby unlocking the connection between the locking pin 3122 and the locking member 321.
