Description

Technical Field

[0001] The present application relates to the technical field of underwater photography equipment, and particularly relates to a lever device for a camera waterproof housing and a camera waterproof housing. Background Art

[0002] Some levers are usually provided on a camera, and these levers are used to access or switch common functions or modes. For example, a power switch lever provided on the top surface of the camera can be toggled to a preset angle or position to control the shutdown and startup of the camera, and some camera models are also provided with a third position to activate video recording or other functions.

[0003] During underwater photography, the camera is usually placed in a camera waterproof housing made of plastic or aluminum alloy materials. The front and rear housings of the camera waterproof housing are of a separable design. After the camera is installed in the front housing, the rear housing can be quickly locked and sealed through a sealing ring and a locking mechanism. An underwater photographer can control and access the camera by toggling a lever device provided outside the camera waterproof housing, which is linked to the power switch lever on the camera through a transmission shaft sealed with the camera waterproof housing and an internal fork.

[0004] In some cases, the power switch lever of the camera is provided at the rear of the top surface of the camera for easy one-handed operation by the user (the user holds the camera with the right hand and the thumb can still toggle the power switch lever); at the same time, some features or functions on the front part of the top surface of the camera are much higher than the power switch lever, such as the main command dial for controlling the aperture. This results in that during the process of installing the camera in the waterproof housing, the features protruding from the front part of the top surface of the camera are likely to interfere with or collide with the power switch lever device of the camera waterproof housing. Summary of the Utility Model

[0005] The present application provides a lever device for a camera waterproof housing and a camera waterproof housing, which solve the problem that the lever device is likely to interfere with and collide with the camera when the camera waterproof housing is installed on the camera.

[0006] To solve the above technical problem, the present application provides a lever device for a camera waterproof housing, including a knob, a fork, a rotating shaft, and a locking assembly.

Both ends of the limiting track in the axial direction of the rotating shaft have limiting surfaces for limiting the movement of the fork. The number of locking positions is two. When the limiting portion abuts against different limiting surfaces, the locking member is engaged with different locking positions.

[0011] In one embodiment, the fork has a jack, and the axial direction of the jack coincides with the axial direction of the rotating shaft. The second end of the rotating shaft is inserted into the jack. The knob can drive the rotating shaft to rotate synchronously, and the rotating shaft can drive the fork to rotate synchronously. The limiting track is a groove-shaped track, and the limiting portion is a spiral member. A threaded hole is further provided at the second end of the rotating shaft, and the spiral member passes through the groove-shaped track and is threadedly connected to the threaded hole.

[0012] In one embodiment, the number of locking assemblies is two, namely a first locking assembly and a second locking assembly. The first locking assembly and the second locking assembly are symmetrically arranged along the axial direction of the rotating shaft. The rotating shaft is provided with a first locking position group for locking with the first locking assembly and a second locking position group for locking with the second locking assembly. The first locking position group and the second locking position group are symmetrically arranged along the axial direction of the rotating shaft.

[0013] In one embodiment, the lever device further includes a limiting member. A limiting groove is provided on the rotating shaft, and the limiting member is clamped in the limiting groove. The limiting member is used for axially positioning the installation of the rotating shaft on the camera waterproof housing.

[0014] In one embodiment, the lever device further includes a sealing ring sleeved on the rotating shaft, and the sealing ring is used to seal the installation of the rotating shaft on the waterproof camera housing.

[0015] To solve the above technical problems, the present application also provides a waterproof camera housing, including a housing and a lever device. The housing includes a front housing and a rear housing. A receiving cavity is provided in the front housing for accommodating a camera. The receiving cavity has an opening for taking in and taking out the camera from the receiving cavity; the rear housing is used to cover and seal the opening; an installation hole is provided on the front housing, and the installation hole connects the receiving cavity with the outside of the housing; the lever device is the lever device for the waterproof camera housing according to any one of the above embodiments; the structure of the rotating shaft between the first end and the second end penetrates through the installation hole and is sealingly connected to the installation hole; the knob is arranged outside the housing, and the fork is arranged inside the receiving cavity.

[0016] The present application provides a lever device for a waterproof camera housing and a waterproof camera housing. The lever device includes a knob, a fork, a rotating shaft and a locking component. A bayonet is provided on the fork for engaging with the lever of the camera; the rotating shaft has a first end and a second end along the axial direction of the rotating shaft. The first end is connected to the knob, and the second end is connected to the fork; the structure of the rotating shaft between the first end and the second end is used for sealing connection with the waterproof camera housing; the locking component is connected to the fork; the locking component has a locking state and an unlocking state; in the locking state, the locking component is used to press against the rotating shaft so that the fork and the rotating shaft are relatively locked; in the unlocking state, the locking component is loose relative to the rotating shaft so that the fork can slide axially along the rotating shaft relative to the rotating shaft to different positions. When the waterproof camera housing of the present application is loaded with a camera, in order to avoid interference between the raised feature at the front of the camera top surface and the lever device, the locking component can be unlocked, so that the fork of the lever device can slide along the rotating shaft towards the knob, that is, the fork can slide upward and can be locked at a position above the rotating shaft, so that the lever device can leave space for the raised feature at the front of the camera top surface, and the two will not interfere or collide.

[0023] The present application will be further described in detail below in conjunction with the accompanying drawings through specific implementation manners. Similar elements in different implementation manners adopt related similar element numbers. In the following implementation manners, many detailed descriptions are provided to enable a better understanding of the present application. 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, or methods.

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.

[0024] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various implementation manners, and the operation steps involved in each embodiment can also be adjusted or reordered in an obvious manner by those skilled in the art. Therefore, the specification and the drawings are only for clearly describing a certain embodiment, and do not mean to be the necessary composition and / or sequence.

[0025] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. The "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0026] The terms "parallel", "perpendicular", etc. are defined in the context of the current technological level, rather than in the strictly absolute mathematical sense. A small deviation is allowed, and approximate parallelism, approximate perpendicularity, etc. are all acceptable. For example, if A is parallel to B, it means that A is parallel to B or approximately parallel to B, and the included angle between A and B can be between 0° and 10°. For example, if A is perpendicular to B, it means that A is perpendicular to B or approximately perpendicular to B, and the included angle between A and B can be between 80° and 100°.

Therefore, the orientation terms are used to better and more clearly illustrate and understand the embodiments of the present application, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation on the embodiments of the present application.

[0027] Please refer to Figures 1-5 , the present application provides a lever device 10 for a waterproof camera housing (the present application may be simply referred to as the lever device 10). The lever device 10 includes a knob 11, a fork 12, a rotating shaft 13, and a locking assembly 14.

[0028] The fork 12 is provided with a bayonet 121, as Figure 6 shown, the bayonet 121 is used to engage with the lever of the camera 20. The lever of the camera 20 can be a power switch lever or a lever for other functions. The power switch lever of the camera 20 can be rotated to turn on and off the camera 20. Preferably, the bayonet 121 of the fork 12 is provided at the lower end of the fork 12 away from the knob 11.

[0029] The rotating shaft 13 has a first end and a second end along the axial direction of the rotating shaft 13. The first end is connected to the knob 11, and the second end is connected to the fork 12. Among them, the knob 11 may have an assembly hole. The first end of the rotating shaft 13 is inserted into the assembly hole, and a screw is inserted into the assembly hole from the end of the knob 11 away from the rotating shaft 13 and is threadedly connected to the first end of the rotating shaft 13 to fasten the knob 11 and the first end of the rotating shaft 13 together. The first end of the rotating shaft 13 can be in a two-flat or four-flat position. Similarly, the assembly hole is also in a two-flat or four-flat position, so that when the first end of the rotating shaft 13 is inserted into the assembly hole, the rotating shaft 13 and the knob 11 cannot rotate relative to each other, and when the user rotates the knob 11, the knob 11 can drive the rotating shaft 13 to rotate synchronously. Of course, the first end of the rotating shaft 13 and the assembly hole can also be in other irregular shapes, and this shape can be used to transmit torque so that the knob 11 can drive the rotating shaft 13 to rotate synchronously.

[0030] The shape of the knob 11 can be generally cylindrical, or it can be as Figures 1-5As shown, a flat toggle portion 111 is provided on the annular side wall of the cylindrical structure. By providing the flat toggle portion 111, it is convenient for the user to toggle the toggle portion 111 underwater to rotate the knob 11. Compared with the cylindrical knob 11, when the flat toggle portion 111 is provided, the user can save more effort when toggling the knob 11.

[0031] The structure of the rotating shaft 13 between the first end and the second end is used for sealing connection with the camera waterproof housing 30. The structure of the rotating shaft 13 between the first end and the second end can be a connecting portion 131. In one embodiment, the lever device 10 further includes a sealing ring 15, which is sleeved on the rotating shaft 13 and sleeved on the connecting portion 131. The sealing ring 15 is used to seal the installation of the rotating shaft 13 on the camera waterproof housing 30. For example, Figure 6 As shown, a mounting hole is provided on the camera waterproof housing 30, a connecting portion 131 passes through the mounting hole, and a sealing ring 15 sleeved on the connecting portion 131 is sealed and connected to the mounting hole to prevent water from entering the interior of the camera waterproof housing 30 through the mounting hole during underwater photography. The sealing ring 15 can ensure the sealing of the camera waterproof housing 30.

[0032] In one embodiment, if Figures 1-5 As shown, the lever device 10 further includes a stopper 16. A stopper groove 132 is provided on the rotating shaft 13. The stopper 16 is clamped in the stopper groove 132. The stopper 16 is used to axially position the rotating shaft 13 on the camera waterproof housing 30. The stopper 16 may be, for example, a retaining spring. The stopper 16 is provided on the connecting portion 131 and on the side of the sealing ring 15 away from the knob 11. Figure 6 As shown, when the sealing ring 15 is sealed and connected to the mounting hole, the limit member 16 and the knob 11 are respectively located on both sides of the mounting hole, and the knob 11 abuts against the outer surface of the camera waterproof housing 30, and the limit member 16 can abut against the inner surface of the camera waterproof housing 30, so that the limit member 16 and the knob 11 can limit the axial direction of the rotating shaft 13 to prevent the rotating shaft 13 and the camera waterproof housing 30 from relative movement in the axial direction of the rotating shaft 13.

[0033] like Figures 1-5 As shown, the locking assembly 14 is connected to the fork 12. The locking assembly 14 has a locked state and an unlocked state. In the locked state, the locking assembly 14 is used to press against the rotating shaft 13 so that the fork 12 and the rotating shaft 13 are relatively locked. In the unlocked state, the locking assembly 14 and the rotating shaft 13 are relatively loose, so that the fork 12 can slide to different positions along the axial direction of the rotating shaft 13 relative to the rotating shaft 13. Since the fork 12 can slide along the axial direction of the rotating shaft 13 in the unlocked state, in the locked state, as shown in FIG. Figures 4-5 As shown, the locking assembly 14 can abut against different axial positions of the rotating shaft 13 .

[0034] As Figures 4-6 shown, after the lever device 10 of the present application is assembled to the waterproof camera housing 30 and before the camera 20 is installed, in order to avoid interference between the protruding feature at the front of the top surface of the camera 20 and the lever device 10, the locking assembly 14 can be unlocked so that the fork 12 of the lever device 10 can slide along the rotating shaft 13 towards the knob 11, that is, the fork 12 can slide upward and can be locked at a position above the rotating shaft 13, so that the lever device 10 can leave space for the protruding feature at the front of the top surface of the camera 20, so that the protruding feature at the front of the top surface of the camera 20 will not interfere with or collide with the fork 12. After the camera 20 is installed, the locking assembly 14 can be unlocked so that the fork 12 slides downward relative to the rotating shaft 13, so that the bayonet 121 of the fork 12 is engaged with the lever of the camera 20, and the fork 12 is locked, so that rotating the knob 11 can synchronously rotate the lever of the camera 20 to realize the function that the user controls the lever of the camera 20 by operating the knob 11 outside the housing. Similarly, before the camera 20 is taken out, the fork 12 is slid upward and locked at a position above the rotating shaft 13, so that the lever device 10 leaves space for the protruding feature at the front of the top surface of the camera 20, preventing the protruding feature from interfering with and colliding with the fork 12, so that the user can smoothly take out the camera 20. In addition, the lever device 10 has a compact structure and simple operation, making the most of the internal space of the waterproof camera housing 30 and making the external features of the waterproof camera housing 30 more concise.

[0035] In one embodiment, as Figures 2-3 shown, the locking assembly 14 includes a locking member 141 and an elastic member 142 connected to each other. At least two recessed locking positions 133 are axially provided on the rotating shaft 13 along the axis of the rotating shaft 13. In the locked state, the elastic force of the elastic member 142 drives the locking member 141 so that the locking member 141 is engaged with the locking position 133. When the locking member 141 is engaged with the locking position 133, the locking member 141 can overcome the gravity of the fork 12 to axially fix the fork 12 at a height opposite to the locking position 133. In the unlocked state, the elastic member 142 undergoes elastic deformation so that the locking member 141 disengages from the locking position 133, so that the fork 12 can drive the locking member 141 to move to a position opposite to a different locking position 133.

[0036] Preferably, two recessed locking positions 133 are axially provided along the rotation axis 13 of the rotation axis 13, namely a first locking position 1331 and a second locking position 1332. The first locking position 1331 and the second locking position 1332 are distributed along the axial direction of the rotation axis 13, and the first locking position 1331 is closer to the side of the knob 11 than the second locking position 1332. Thus, the locking assembly 14 has two locking states, namely a first locking state and a second locking state. In the first locking state, the locking member 141 is engaged with the first locking position 1331. In the second locking state, the locking member 141 is engaged with the second locking position 1332. In the unlocked state, the fork 12 can drive the locking member 141 to move between the first locking position 1331 and the second locking position 1332, so that the locking member 141 moves to a position opposite to the first locking position 1331 or moves to a position opposite to the second locking position 1332.

[0037] Before the camera 20 is installed in the camera waterproof housing 30, first push the fork 12 to drive the locking member 141 to move towards the first locking position 1331. When the locking member 141 moves to a position opposite to the first locking position 1331, under the elastic force of the elastic member 142, the locking member 141 snaps into the first locking position 1331 (as shown in Figure 5 ), and the locking member 141 axially fixes the fork 12 by overcoming the own weight of the fork 12, preventing the fork 12 from falling down and avoiding interference between the fork 12 and the structure in front of the top of the camera 20 during the process of installing the camera 20 into the camera waterproof housing 30, which may hinder the installation. After the camera 20 is installed in the camera waterproof housing 30, push the fork 12 to drive the locking member 141 to move towards the second locking position 1332. When the locking member 141 moves to a position opposite to the second locking position 1332, under the elastic force of the elastic member 142, the locking member 141 snaps into the second locking position 1332 (as shown in Figure 4 and Figure 6 ), at this time, the bayonet 121 at the lower end of the fork 12 is engaged with the lever of the camera 20. Rotating the knob 11 can drive the fork 12 to rotate synchronously through the rotation axis 13, so as to realize that the lever device 10 drives the lever of the camera 20 to rotate, and realize the function of controlling the lever of the camera 20 outside the camera waterproof housing 30 by operating the lever device 10.

[0038] Before the camera 20 is taken out of the camera waterproof housing 30, first push the fork 12 to drive the locking member 141 to move towards the first locking position 1331. When the locking member 141 moves to a position opposite to the first locking position 1331, under the elastic force of the elastic member 142, the locking member 141 snaps into the first locking position 1331 (as shown in Figure 5 ), and at this time, the camera 20 can be smoothly taken out of the camera waterproof housing 30. Through the cooperation of the locking member 141, the elastic member 142 and the locking position 133, the automatic self-locking and automatic unlocking of the locking member 141 can be realized.

[0039] In other embodiments, the rotating shaft 13 may not have a recessed locking position 133. The locking assembly 14 may be a component such as a screw. In the locked state, the screw can fasten the fork 12 and the rotating shaft 13 together to prevent the fork 12 from falling downward due to its own gravity. In the unlocked state, loosening the screw can make the fork 12 and the rotating shaft 13 relatively loose, so that the fork 12 can adjust its relative position with respect to the rotating shaft 13 in the axial direction of the rotating shaft 13. However, this method is more troublesome compared to the method using the above-mentioned elastic member 142 and locking member 141. With the screw method, the screw itself cannot automatically lock, and the user needs to repeatedly tighten and loosen the screw, making the operation of loading or removing the camera 20 into or from the camera waterproof housing 30 very cumbersome. While in the method using the elastic member 142 and locking member 141, the elastic force of the elastic member 142 itself can achieve self-locking at the locking position 133 and unlocking from the locking position 133. The user only needs to push the fork 12 to switch between the locked state and the unlocked state, which not only solves the problem of interference between the lever device 10 and the camera 20, but also makes the operation of loading and removing the camera 20 into and from the camera waterproof housing 30 not overly cumbersome.

[0040] In one embodiment, as Figure 2 shown, the locking member 141 is a spherical ball, and the elastic member 142 is a spring. In the locked state, a part of the spherical ball is embedded in the locking position 133. Among them, the locking position 133 can be matched with a part of the structure of the spherical ball, and the diameter of the opening of the locking position 133 is smaller than the diameter of the spherical ball, so that only a structure less than half of the spherical ball can be embedded in the locking position 133 to prevent the spherical ball from being stuck in the locking position 133 when the fork 12 is axially moved, resulting in the fork 12 being unable to axially move and unlock.

[0041] In one embodiment, as Figures 1-5 shown, the locking assembly 14 further includes a fixing member 143. The fixing member 143 is fixedly connected to the fork 12, for example, by screws. An installation groove 1431 is provided on one side of the fixing member 143 facing the fork 12. A through hole 122 is provided at a position of the fork 12 opposite to the installation groove 1431. The locking position 133 is provided on one side of the rotating shaft 13 facing the through hole 122; one end of the elastic member 142 is connected in the installation groove 1431, and the other end of the elastic member 142 abuts against the locking member 141. The locking member 141 passes through the through hole 122 for engaging with the locking position 133. By providing the fixing member 143, it is convenient to install the elastic member 142 and the locking member 141 on the fork 12.

[0042] In one embodiment, as Figures 1-5As shown, the shift lever device 10 further includes a limiting portion 17. A limiting track 123 is provided on the shift fork 12. The limiting track 123 can be linear, and the extending direction of the limiting track 123 is parallel to the axial direction of the rotating shaft 13. The limiting track 123 can be, for example, a linear groove-shaped track. One end of the limiting portion 17 is slidably connected or in clearance fit with the limiting track 123, and the other end of the limiting portion 17 is fixedly connected to the rotating shaft 13. Both ends of the limiting track 123 in the axial direction of the rotating shaft 13 have limiting surfaces 1231, and the two limiting surfaces 1231 are respectively used to limit the upward and downward sliding of the shift fork 12. Two or two rows of locking positions 133 can be provided in the axial direction of the rotating shaft 13. When the limiting portion 17 abuts against different limiting surfaces 1231, the locking member 141 is engaged with different locking positions 133 in the axial direction of the rotating shaft 13. As Figure 4 shown, when the limiting portion 17 abuts against the limiting surface 1231 at one end of the limiting track 123 close to the knob 11, the locking member 141 is engaged with the second locking position 1332; as Figure 5 shown, when the limiting portion 17 abuts against the limiting surface 1231 at the end of the limiting track 123 away from the knob 11, the locking member 141 is engaged with the first locking position 1331. By providing the limiting cooperation between the limiting portion 17 and the limiting track 123, the limiting track 123 can limit the movement of the shift fork 12 in the axial direction, and when the shift fork 12 abuts against different limiting surfaces 1231 of the limiting track 123, the locking member 141 is engaged with different locking positions 133. The cooperation between the limiting portion 17 and the limiting track 123 can also prevent relative rotation between the rotating shaft 13 and the shift fork 12, so that the rotation of the rotating shaft 13 can drive the shift fork 12 to rotate synchronously.

[0043] Furthermore, as Figure 2 and Figure 3As shown, the fork 12 has a jack 124, the axial direction of the jack 124 coincides with the axial direction of the rotating shaft 13, and the second end of the rotating shaft 13 is inserted into the jack 124. By configuring the shapes of the second end of the rotating shaft 13 and the jack 124, the rotating shaft 13 can transmit torque to the fork 12, so that the rotating shaft 13 can drive the fork 12 to rotate synchronously. The second end of the rotating shaft 13 can be in the shape of a two-flat position or a four-flat position. Similarly, the jack 124 is also in the shape of a two-flat position or a four-flat position, so that when the second end of the rotating shaft 13 is inserted into the jack 124, the rotating shaft 13 and the fork 12 cannot rotate relative to each other. When the knob 11 drives the rotating shaft 13 to rotate synchronously, the rotating shaft 13 can drive the fork 12 to rotate synchronously. Of course, the second end of the rotating shaft 13 and the jack 124 can also be in other irregular shapes, and this shape can be used to transmit torque so that the rotating shaft 13 can drive the fork 12 to rotate synchronously. The limiting track 123 is a groove-shaped track, the limiting part 17 is a spiral part, and a threaded hole is also provided at the second end of the rotating shaft 13. The spiral part passes through the groove-shaped track and is threadedly connected to the threaded hole. By threadedly connecting the spiral part and the threaded hole, the relative rotation of the rotating shaft 13 and the fork 12 can be prevented.

[0044] In one embodiment, as Figures 1-5 shown, the number of the locking components 14 is two, namely a first locking component 144 and a second locking component 145. The first locking component 144 and the second locking component 145 are symmetrically arranged along the axial direction of the rotating shaft 13. The rotating shaft 13 is provided with a first locking position group for locking with the first locking component 144 and a second locking position group for locking with the second locking component 145. The first locking position group and the second locking position group are symmetrically arranged along the axial direction of the rotating shaft 13. For example, there are two first locking positions 1331 symmetrically arranged along the axial direction of the rotating shaft 13 and two second locking positions 1332 symmetrically arranged along the axial direction of the rotating shaft 13 on the rotating shaft 13. A first locking position 1331 and a second locking position 1332 form a first locking position group, and the other first locking position 1331 and the other second locking position 1332 form a second locking position group. The first locking position group and the second locking position group are symmetrically arranged along the axial direction of the rotating shaft 13. By symmetrically arranging the first locking component 144 and the second locking component 145 along the axial direction of the rotating shaft 13, the locking of the fork 12 can be made more stable and reliable, so that more locking parts can overcome the gravity of the fork 12 to lock the fork 12.
