[0007] In one embodiment, the lever device further includes a second rotating shaft. The fixed seat has a first hinge hole and a limiting surface. The fork has a connecting portion provided with a second hinge hole. The second rotating shaft passes through the second hinge hole and the first hinge hole to hinge the connecting portion to the fixed seat. The limiting surface is disposed near the first hinge hole and is used to limit the connecting portion so that the connecting portion swings relative to the fixed seat within a preset range.

[0008] In one embodiment, a first mounting hole is provided at one end of the fixed seat away from the first hinge hole, and a second mounting hole is provided at one end of the fork away from the second hinge hole. One end of the elastic member is mounted in the first mounting hole, and the other end of the elastic member is mounted in the second mounting hole. The bayonet and the elastic member are arranged on both sides of the fork along the axial direction of the first rotating shaft.

[0009] In one embodiment, the fork has a guide post, and the fixed seat has a third mounting hole. One end of the guide post near the fixed seat is disposed in the third mounting hole, and the guide post can slide closer to and away from the knob in the third mounting hole. The elastic member is a spring sleeved on the guide post. One end of the spring is connected to the third mounting hole, and the other end of the spring is connected to the fork.

[0010] In one embodiment, the lever device further includes a pin. The fixed seat is provided with a limiting hole, and the fork further has a limiting boss provided with a limiting groove, and the extending direction of the limiting groove is parallel to the axial direction of the first rotating shaft. The pin is inserted into the limiting hole and the limiting groove to limit the sliding stroke of the fork relative to the fixed seat in the axial direction of the first rotating shaft.

[0011] In one embodiment, the lever device further includes a limiting member. A limiting groove is provided on the first rotating shaft, and the limiting member is clamped in the limiting groove. The limiting member is used for axially positioning the installation of the lever device on the camera waterproof housing.

[0012] In one embodiment, the lever device further includes a sealing ring. A sealing ring is sleeved on the first rotating shaft, and a waterproof groove is further provided on the first rotating shaft. The sealing ring is used for sealing the installation of the lever device on the camera waterproof housing, and the waterproof groove is used for waterproofing.

[0013] In one embodiment, the lever device further includes a connecting shaft sleeve sleeved on the first rotating shaft, and the connecting shaft sleeve is disposed on the side of the knob close to the fixed seat. The connecting shaft sleeve is used for sealing connection with the camera waterproof housing.

[0014] To solve the above technical problems, the present application further provides a camera waterproof housing, including a housing and a lever device. A receiving cavity is provided inside the housing for receiving the camera. The lever device is assembled on the housing. The lever device is the lever device described in any of the above embodiments, and the knob is disposed outside the housing, and the fork is disposed inside the receiving cavity.

[0015] The present application provides a lever device for a camera waterproof housing and a camera waterproof housing. The lever device includes a knob, a fixed seat, a first rotating shaft, a fork and an elastic member. The first rotating shaft has a first end and a second end along the axial direction of the first rotating shaft. The first end is fixedly connected to the knob, and the second end is fixedly connected to the fixed seat. The fork is connected to the fixed seat, and the fork can float relative to the fixed seat. One end of the fork away from the fixed seat has a first latch and a second latch, and a bayonet is formed between the first latch and the second latch for engaging with the lever of the camera. The elastic member is arranged between the fixed seat and the fork and is used to generate an elastic restoring force when the first latch or the second latch floats towards the fixed seat, and the elastic restoring force can drive the first latch or the second latch away from the fixed seat. When the camera is installed in the camera waterproof housing, when the lever of the camera does not engage with the bayonet of the fork, the lever of the camera will abut against the first latch or the second latch of the fork. Since the fixed seat of the present application is relatively fixed with the camera waterproof housing in the axial direction of the first rotating shaft, and the fork can float relative to the fixed seat, when the lever of the camera presses the first latch or the second latch, the fork and the fixed seat will move closer to each other, causing the elastic member to generate a stronger elastic restoring force. The user can rotate the knob outside the camera waterproof housing, and the knob drives the fork to rotate synchronously until the bayonet of the fork is opposite to the lever of the camera. Due to the elastic restoring force of the elastic member, the elastic member will push the fork away from the fixed seat so that the bayonet snaps into the lever of the camera. When the user hears or feels a "pop" sound when the bayonet snaps into the lever, the lever device can be used to control the lever switch of the camera normally. Even when the camera is installed, if the bayonet of the present application does not align with the camera lever, when the user finds that the switch function is abnormal after getting into the water, the bayonet can be automatically latched with the lever by rotating the knob, without having to return to the water surface to reinstall the camera, nor does the user need to be particularly careful whether the bayonet engages with the lever during the process of installing the camera on the water surface, which improves the user's underwater shooting progress and experience.

[0026] Please refer to Figures 1-6 The present application provides a lever device 10 for a camera waterproof housing (hereinafter referred to as the lever device 10 ). The lever device 10 includes a knob 11 , a fixing seat 12 , a first rotating shaft 13 , a shift fork 14 and an elastic member 15 .

[0027] The first rotating shaft 13 has a first end and a second end along the axial direction of the first rotating shaft 13, the first end is fixedly connected to the knob 11, and the second end is fixedly connected to the fixing seat 12. The knob 11 may have a first assembly hole 111, the first end of the first rotating shaft 13 is inserted into the first assembly hole 111, the first screw 161 is inserted into the first assembly hole 111 from the end of the knob 11 away from the first rotating shaft 13, and is threadedly connected with the first end of the first rotating shaft 13, so as to fasten the knob 11 and the first end of the first rotating shaft 13 together. The fixing seat 12 has a second assembly hole 121, the second end of the first rotating shaft 13 is inserted into the second assembly hole 121, the second screw 162 is inserted into the second assembly hole 121 from the end of the fixing seat 12 away from the knob 11, and is threadedly connected with the second end of the first rotating shaft 13, so as to fasten the second end of the first rotating shaft 13 and the fixing seat 12 together.

[0028] The first end and the second end of the first rotating shaft 13 can be in a two-sided flattened position or a square flattened position. Similarly, the first assembly hole 111 and the second assembly hole 121 can also be in a two-sided flattened position or a square flattened position, so that when the first end of the first rotating shaft 13 is inserted into the first assembly hole 111, the first rotating shaft 13 and the knob 11 cannot rotate relative to each other, and when the second end of the first rotating shaft 13 is inserted into the second assembly hole 121, the first rotating shaft 13 and the fixed seat 12 cannot rotate relative to each other, so that when the user rotates the knob 11, the knob 11 can drive the first rotating shaft 13 to rotate synchronously, and the first rotating shaft 13 drives the fixed seat 12 to rotate synchronously.

[0029] The shape of the knob 11 can be roughly cylindrical, or it can be Figures 1-6 As shown, a flat toggle portion 112 is provided on the annular side wall of the cylindrical structure. By providing the flat toggle portion 112, it is convenient for the user to toggle the toggle portion 112 underwater to rotate the knob 11. Compared with the cylindrical knob 11, when the flat toggle portion 112 is provided, the user can save more effort when toggling the knob 11.

[0030] The structure of the first rotating shaft 13 between the first end and the second end may be a mounting portion 132. In one embodiment, the lever device 10 further includes a sealing ring 17, the first rotating shaft 13 is sleeved with the sealing ring 17, and the sealing ring 17 is sleeved on the mounting portion 132. The sealing ring 17 is used to seal the installation of the lever device 10 on the camera waterproof housing. In one embodiment, a waterproof groove is also provided on the first rotating shaft 13, and the waterproof groove can also be used for waterproofing.

[0031] In one embodiment, as Figures 1-6 shown, the lever device 10 further includes a limiting member 18. A limiting groove 131 is provided on the first rotating shaft 13, and the limiting member 18 is clamped in the limiting groove 131. The limiting member 18 is used for axially positioning the installation of the first rotating shaft 13 on the camera waterproof housing. The limiting member 18 can be, for example, a snap ring. The limiting member 18 is arranged on the mounting portion 132 and on the side of the sealing ring 17 away from the knob 11. The limiting member 18 can prevent the first rotating shaft 13 from moving outward in the axial direction of the first rotating shaft 13 towards the outside of the camera waterproof housing.

[0032] In one embodiment, the lever device 10 further includes a connecting bushing 19. The connecting bushing 19 is sleeved on the first rotating shaft 13, and the connecting bushing 19 is arranged on the side of the knob 11 close to the fixed seat 12. The connecting bushing 19 is used for sealing connection with the camera waterproof housing. For example, a threaded hole can be provided on the camera waterproof housing, and an external thread is provided on the connecting bushing 19. The lever device 10 is installed on the camera waterproof housing by threading the external thread of the connecting bushing 19 with the threaded hole of the camera waterproof housing. If the first rotating shaft 13 is directly matched with the hole position of the camera waterproof housing, the first rotating shaft 13 may be worn or corroded during long-term use. By providing the connecting bushing 19 to replace the direct cooperation between the first rotating shaft 13 and the camera waterproof housing, the connecting bushing 19 can be made of wear-resistant material. When used for a long time, the connecting bushing 19 can be replaced, which is beneficial to after-sales maintenance and repair.

[0033] At least a part of the fork 14 is arranged at one end of the fixed seat 12 away from the knob 11, and the end of the fork 14 away from the fixed seat 12 has a first leg 141 and a second leg 142. A bayonet 143 is formed between the first leg 141 and the second leg 142, as Figure 4 shown. The bayonet 143 is used for engaging with the lever 21 of the camera 20. The lever 21 of the camera 20 can be a power switch lever or a lever for other functions. The power switch lever 21 of the camera 20 can turn on and off the camera 20 by rotation. Preferably, the bayonet 143 of the fork 14 is arranged at the lower end of the fork 14 away from the knob 11.

[0034] The fork 14 is connected to the fixed seat 12, and the fork 14 can float relative to the fixed seat 12. Floating means that the fork 14 can rotate (swing) relative to the fixed seat 12 within a preset angle, and / or the fork 14 can slide in a preset stroke in the directions away from and towards the fixed seat 12. In short, the fork 14 can move within a preset range relative to the fixed seat 12.

[0035] The elastic member 15 is disposed between the fixed seat 12 and the fork 14. One end of the elastic member 15 is connected to the fixed seat 12, and the other end of the elastic member 15 is connected to the fork 14. The elastic member 15 is used to generate an elastic restoring force when the first leg 141 or the second leg 142 floats toward the fixed seat 12, and the elastic restoring force can drive the first leg 141 or the second leg 142 away from the fixed seat 12.

[0036] When the camera 20 is installed in the camera waterproof housing, when the lever 21 of the camera 20 and the bayonet 143 of the fork 14 are not relatively engaged (as Figure 3 shown), the lever 21 of the camera 20 will abut against the first leg 141 or the second leg 142 of the fork 14. Since the fixed seat 12 of the present application and the camera waterproof housing are relatively fixed in the axial direction of the first rotation axis 13, and the fork 14 and the fixed seat 12 can float relative to each other, when the lever 21 of the camera 20 presses the first leg 141 or the second leg 142, the fork 14 will move relatively closer to the fixed seat 12, causing the elastic member 15 to be further compressed to generate a stronger elastic restoring force. The user can rotate the knob 11 outside the camera waterproof housing, and the knob 11 drives the fork 14 to rotate synchronously until the bayonet 143 of the fork 14 is aligned or coincides with the lever 21 of the camera 20. Due to the elastic restoring force of the elastic member 15, the elastic member 15 will push the fork 14 away from the fixed seat 12 so that the bayonet 143 is inserted into the lever 21 of the camera 20 (as Figure 4 shown). The user can hear or feel a "pop" sound when the bayonet 143 is inserted into the lever 21, and then the lever device 10 can be used to control the lever 21 switch normally. Even when the camera 20 is installed, if the bayonet 143 and the lever 21 of the camera 20 do not correspond, when the user finds that the switch function is abnormal after getting into the water, the bayonet 143 and the lever 21 can be automatically latched by rotating the knob 11. There is no need to return to the water surface to reinstall the camera 20, nor does the user need to be extra careful whether the bayonet 143 is engaged with the lever 21 during the installation of the camera 20 on the water, which improves the user's underwater shooting progress and experience. The present application not only simplifies the installation process of the camera 20, but also enables the user to operate more simply and quickly underwater through the automatic alignment of the lever device 10, and realizes safe and reliable underwater shooting.

[0037] In addition, by presetting the widths of the first leg 141 and the second leg 142 of the fork 14, it is possible to prevent the fork 14 from completely falling into either side of the lever 21 of the camera 20, and the automatic alignment operation can be made easier and smoother.

[0038] In one embodiment, as Figure 2As shown, the elastic member 15 is a spring. In other embodiments, the elastic member 15 may also be a spring piece, for example. The spring remains in a compressed state. When the bayonet 143 of the fork 14 engages with the lever 21 of the camera 20, under the action of the elastic restoring force of the spring, the buckle can always fit with the lever 21, so as to ensure that the bayonet 143 and the lever 21 remain engaged, thereby improving the stability and reliability of the lever device 10 for manipulating the lever 21 of the camera 20.

[0039] As Figure 1 and Figure 2 As shown, in one embodiment, the lever device 10 further includes a second rotating shaft 30. The fixed seat 12 has a first hinge hole 122 and a limiting surface 123. The fork 14 has a connecting portion 144, and a second hinge hole 1441 is provided on the connecting portion 144. The second rotating shaft 30 passes through the second hinge hole 1441 and the first hinge hole 122 to hinge the connecting portion 144 to the fixed seat 12. The limiting surface 123 is arranged close to the first hinge hole 122. The limiting surface 123 is used to limit the connecting portion 144, so that the connecting portion 144 swings relative to the fixed seat 12 within a preset range, that is, the fork 14 can rotate relative to the fixed seat 12 within a preset angle, so that the fork 14 moves away from or close to the fixed seat 12. Preferably, the preset angle at which the fork 14 can rotate is slightly larger than the working angle of the lever 21 of the camera 20.

[0040] Further, a first mounting hole (not shown in the figure) is provided at one end of the fixed seat 12 away from the first hinge hole 122, and a second mounting hole 145 is provided at one end of the fork 14 away from the second hinge hole 1441. One end of the elastic member 15 is mounted in the first mounting hole, and the other end of the elastic member 15 is mounted in the second mounting hole 145. The bayonet 143 and the elastic member 15 are arranged on both sides of the fork 14 along the axial direction of the first rotating shaft 13. Since the swing angle on the side of the fork 14 away from the second rotating shaft 30 is larger, and the elastic member 15 is arranged away from the second rotating shaft 30, it can ensure that the elastic member 15 has enough assembly space for assembly. By arranging the bayonet 143 and the elastic member 15 on both sides of the fork 14, the elastic restoring force of the elastic member 15 can be easily transmitted to the bayonet 143, thereby facilitating the engagement of the bayonet 143 with the lever 21 of the camera 20.

[0041] Please refer to Figure 5 and Figure 6, in one embodiment, the shift fork 14 has a guide post 146, and the fixed seat 12 has a third mounting hole 124. One end of the guide post 146 close to the fixed seat 12 is arranged in the third mounting hole 124, and the guide post 146 can slide close to and away from the knob 11 in the third mounting hole 124. The elastic member 15 is a spring, the spring is sleeved on the guide post 146, one end of the spring is connected to the third mounting hole 124, and the other end of the spring is connected to the shift fork 14. In this embodiment, the guide post 146 can slide close to and away from the knob 11 in the third mounting hole 124, so as to guide the shift fork 14 to slide close to and away from the fixed seat 12, so that the shift fork 14 can float relative to the fixed seat 12. When the guide post 146 slides close to the fixed seat 12, the spring can be synchronously compressed, so that the spring generates an elastic restoring force. The elastic restoring force is used to push the shift fork 14 away from the fixed seat 12 when the bayonet 143 and the shift lever 21 of the camera 20 are oppositely arranged, so that the bayonet 143 and the shift lever 21 are engaged.

[0042] Further, the shift lever device 10 further includes a pin 40. The fixed seat 12 is provided with a limit hole 125. The shift fork 14 further has a limit boss 147. A limit groove 1471 is provided on the limit boss 147, and the extending direction of the limit groove 1471 is parallel to the axial direction of the first rotation axis 13; the pin 40 is inserted into the limit hole 125 and the limit groove 1471 to limit the sliding stroke of the shift fork 14 relative to the fixed seat 12 in the axial direction of the first rotation axis 13, so as to realize that the shift fork 14 can only slide relative to the fixed seat 12 within a small range.

[0043] In one embodiment, the fixed seat 12 is further provided with an assembly groove 126. The limit hole 125 is arranged on the hole wall of the assembly groove 126, and the axial direction of the limit hole 125 is perpendicular to the axial direction of the first rotation axis 13. The limit boss 147 is inserted into the assembly groove 126. The pin 40 passes through the limit hole 125 and the limit groove 1471 of the limit boss 147 in the assembly groove 126. The pins 40 can be symmetrically arranged on both sides of the assembly groove 126 along the radial direction of the first rotation axis 13, and the pin 40 is in interference fit with the limit hole 125.

[0044] The present application also provides a waterproof camera housing (not shown in the figure). The waterproof camera housing includes a housing and a shift lever device 10. A receiving cavity is arranged in the housing, and the receiving cavity is used to receive the camera 20. The shift lever device 10 is assembled on the housing, and the knob 11 of the shift lever device 10 is arranged outside the housing, and the shift fork 14 is arranged inside the receiving cavity. The shift lever device 10 can have the same or similar structure as the shift lever device 10 involved in any of the above embodiments, so that the waterproof camera housing can achieve the same or similar functions, which will not be elaborated here.

[0045] The above uses specific examples to elaborate on the present utility model, which is only used to help understand the present utility model and is not intended to limit the present utility model. For those skilled in the technical field to which the present utility model pertains, based on the idea of the present utility model, several simple deductions, deformations or substitutions can also be made.
