Description

Technical Field

[0001] The invention relates to photographic equipment, and in particular to a flippable camera quick-release plate and a rotating shaft mechanism. Background Art

[0002] The camera quick release plate is a platform installed on the gimbal to fix the camera. The camera and the camera quick release plate are usually fixed, and the camera quick release plate can be rotated to a certain angle using the ball joint of the gimbal. However, due to the structural limitations of the ball joint, the camera quick release plate cannot be deflected 90 degrees relative to the gimbal, which limits the camera's shooting angle.

[0003] China Utility Model Patent Specification No. 2022218723946 discloses a camera quick-release plate that can be changed to multiple angles. It mainly realizes that the upper flap can be fixed when it is unfolded to multiple angles by setting end teeth or friction plates on the end faces of the pivoting part and the locking member. For example, the upper flap can be unfolded to multiple angles between 0° and 90° according to the shooting angle. However, the disadvantage of this structure of the camera quick-release plate is that the camera cannot be shot vertically upward or downward. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a flippable camera quick-release plate, which can enable the camera to shoot between 0° and 90°, and can also enable the camera to shoot vertically upward or downward; at the same time, the present invention also provides a rotating shaft mechanism.

[0009] In one embodiment, an elastic positioning member is installed in a mounting hole on the side of the upper flap, and the elastic positioning member includes a positioning pin, a compression spring, and a screw plug in order from the inside to the outside. The inner end of the positioning pin contacts the circumference of the circular boss of the quick-release plate connecting member, and a plurality of arc-shaped shallow grooves are evenly distributed on the circumference of the circular boss of the quick-release plate connecting member corresponding to the positioning pin. When the quick-release plate connecting member rotates, the positioning pin encounters the arc-shaped shallow groove on the circumference of the circular boss under the action of the compression spring, and a "click" impact sound is emitted, thereby serving as a prompt.

[0010] In one embodiment, the rotating shaft mechanism includes a U-shaped portion, a pivoting portion and a rotating shaft. One of the base plate and the upper flip plate is selected to have a pivoting portion with an axial hole at one end, and the other is selected to have a U-shaped portion at one end. The U-shaped portion includes a left ear plate and a right ear plate, both of which are provided with axial holes. The pivoting portion is embedded between the two ear plates of the U-shaped portion and the rotating shaft is installed. The axial holes of the two ear plates of the U-shaped portion are both provided with internal splines. The axial hole of the pivoting portion has a section provided with an internal spline. The rotating shaft is a spline shaft. There is a The section is the bare rod portion; the two end portions of the rotating shaft are inserted into the axial holes of the left ear plate and the right ear plate and can only make axial movement relative to the left ear plate and the right ear plate but not circumferential movement; a return spring is installed between the rotating shaft and the left ear plate or the right ear plate, and under the elastic force of the return spring, the external spline in the middle of the rotating shaft and the internal spline in the middle of the axial hole of the pivot part are in a meshing state; when pressing force or pulling force is applied to the rotating shaft to overcome the elastic force of the return spring and move in the reverse direction, the bare rod portion of the rotating shaft corresponds to the internal spline of the pivot part, and the pivot part can rotate around the rotating shaft at this time.

[0011] In one embodiment, the axial holes of the left ear plate and the right ear plate are both stepped holes with a smaller inner side and a larger outer side. A nut protruding from the left ear plate is installed at the left end of the rotating shaft, an annular baffle plate and a retaining ring are installed at the right end of the rotating shaft, an end cover is installed at the outer side of the axial hole of the right ear plate, the return spring is installed between the retaining ring and the step surface of the axial hole of the right ear plate or between the nut and the step surface of the axial hole of the left ear plate, and a locking mechanism is provided at the position of the outer section of the axial hole of the right ear plate, and the locking mechanism can prevent the rotating shaft from resetting by cooperating with the annular baffle plate.

[0012] In one embodiment, the locking mechanism includes a shell and a locking pin, a spring and a screw plug installed in the shell.

The locking pin of the locking mechanism penetrates into the shaft hole of the right ear plate through the radial through hole, with the inclined surface on the locking pin facing inward. The movable block faces outward; a conical surface is provided on the right side surface of the annular baffle. When the rotating shaft moves to the right, the conical surface of the annular baffle can cooperate with the inclined surface on the locking pin, thereby applying a downward pressure to the locking pin, pressing the end of the locking pin into the radial through hole. After the annular baffle passes over the radial through hole, the end of the locking pin quickly rebounds into the shaft hole of the right ear plate under the elastic force of the spring. At this time, the end of the locking pin just blocks it from the left side of the annular baffle, thereby locking the axial position of the rotating shaft. At this time, the locking pin can only release the blocking of the annular baffle by pushing the toggle block downward by hand to drive the locking pin to move downward.

[0013] In one embodiment, a small through hole parallel to the shaft hole is provided below the shaft hole of the left ear plate, and a positioning pin, a spring, and a plug are installed in the small through hole from inside to outside in sequence, and the inner end of the positioning pin abuts against the left end surface of the pivoting part, and the left end surface of the pivoting part is provided with a plurality of arc-shaped shallow grooves that can cooperate with the positioning pin. When the pivoting part rotates relative to the rotating shaft, the positioning pin encounters the arc-shaped shallow groove on the left end surface of the pivoting part under the action of the spring, and a "click" impact sound is emitted, thereby serving as a prompt.

[0014] In one embodiment, a groove is provided downwardly in the middle of the U-shaped portion to separate the two ear plates, and a screw hole is provided perpendicularly to the groove, and an adjustment screw is installed in the screw hole. This structure can facilitate the adjustment of the distance between the two ear plates.

[0015] The working principle and operation description of the present invention are as follows:

[0016] 1) In the default state of the shaft mechanism, due to the elastic force of the return spring, the external spline of the shaft and the internal spline in the middle of the shaft hole of the pivot part are in meshing state;

[0017] 2) Press or pull the shaft by hand to make it move axially in the direction opposite to the spring force until the bare rod in the middle of the shaft corresponds to the internal spline in the middle of the shaft hole of the pivot joint;

[0018] 3) Move the upper flap to rotate around the shaft so that the angle between the upper flap and the base plate reaches the required angle, and then release the intervening force on the shaft. The shaft will return to its original position under the elastic force of the return spring, so that the shaft mechanism returns to the locked state;

[0019] 4) Rotate the quick-release plate coupling to the desired angle, and then secure the quick-release plate coupling at that angle with the manual locking member.

[0020] The present invention can not only ensure that the upper flap can be fixed when it is unfolded to various angles, for example, the upper flap can be unfolded to various angles between 0° and 90° according to the needs of the shooting angle, but also enable the camera to rotate 360° relative to the upper flap, thereby realizing vertical downward shooting and vertical upward shooting of the camera.

[0021] Based on the same inventive concept, the present invention also provides a rotating shaft mechanism, including a first connecting member, a second connecting member and a rotating shaft. One of the first connecting member and the second connecting member is selected to have a pivot portion with an axial hole at one end thereof, and the other is selected to have a U-shaped portion at one end thereof. The U-shaped portion includes a left ear plate and a right ear plate both of which are provided with axial holes.

The left ear plate and the right ear plate can make axial movement but not circumferential movement, and a return spring is installed between the rotating shaft and the left ear plate or the right ear plate. Under the elastic force of the return spring, the external spline in the middle of the rotating shaft and the internal spline in the middle of the shaft hole of the pivot part are in a meshing state. When pressing force or pulling force is applied to the rotating shaft to overcome the elastic force of the return spring and move in the opposite direction, the smooth rod part of the rotating shaft corresponds to the internal spline of the pivot part. At this time, the pivot part can rotate around the rotating shaft; the shaft holes of the left ear plate and the right ear plate are both stepped holes with a small inner side and a large outer side. A nut protruding from the left ear plate is installed at the left end of the rotating shaft, an annular baffle and a retaining ring are installed at the right end of the rotating shaft, an end cover is installed on the outer side of the shaft hole of the right ear plate, and the return spring The spring is installed between the retaining ring and the step surface of the right ear plate shaft hole or between the nut and the step surface of the left ear plate shaft hole. The right ear plate is provided with a locking mechanism at the position of the outer section of the shaft hole corresponding to the right ear plate, and the locking mechanism can prevent the rotating shaft from resetting by cooperating with the annular baffle; the locking mechanism includes a shell and a locking pin, a spring and a screw plug installed in the shell. Under the preload force of the spring, the locking pin has a section extending outward from the through hole at one end of the shell and its end face is an inclined surface. A toggle block perpendicular to the locking pin is provided on the side of the locking pin, and the toggle block protrudes outward through the strip hole on the side of the shell; the locking mechanism is installed in the square groove below the shaft hole of the right ear plate, and a radial through hole communicating with the square groove is provided on the inner wall of the shaft hole of the right ear plate The locking pin is inserted into the shaft hole of the right ear plate through the radial through hole, with the inclined surface on the locking pin facing inward and the toggle block facing outward; the right side surface of the annular baffle is provided with a conical surface, and when the rotating shaft moves to the right, the conical surface of the annular baffle can cooperate with the inclined surface on the locking pin, thereby applying a downward pressure to the locking pin and pressing the end of the locking pin into the radial through hole. After the annular baffle passes over the radial through hole, the end of the locking pin quickly rebounds into the shaft hole of the right ear plate under the elastic force of the spring. At this time, the end of the locking pin just blocks it from the left side of the annular baffle, thereby locking the axial position of the rotating shaft. At this time, the locking pin can only be released from the blocking of the annular baffle by pushing the toggle block downward by hand to drive the locking pin to move downward.

[0050] like Figure 1 , 6 As shown in FIG. 8 , an elastic positioning member is installed in a mounting hole on the side of the upper flap 20. The elastic positioning member includes a positioning pin 84, a compression spring, and a screw plug in order from the inside to the outside. The inner end of the positioning pin 84 contacts the circumference of the circular boss of the quick-release plate connecting member 80. A plurality of arc-shaped shallow grooves a are evenly distributed on the circumference of the circular boss of the quick-release plate connecting member 80 corresponding to the positioning pin 84. When the quick-release plate connecting member 80 rotates, the positioning pin 84 encounters the arc-shaped shallow grooves a on the circumference of the circular boss under the action of the compression spring, and a "click" impact sound is emitted, thereby serving as a reminder.

[0051] like Figures 9 to 14As shown, the rotating shaft mechanism includes a U-shaped portion, a pivoting portion 21 with an axial hole and a rotating shaft 30. The pivoting portion 21 is arranged on the upper flap 20, and the U-shaped portion is arranged on the base plate 10. The U-shaped portion includes a left ear plate 11 and a right ear plate 12, both of which are provided with axial holes. The pivoting portion 21 is embedded between the two ear plates of the U-shaped portion and the rotating shaft 30 is installed. The axial holes of the two ear plates of the U-shaped portion are both provided with internal splines. The axial hole of the pivoting portion 21 has a section provided with an internal spline 22. The rotating shaft 30 is a spline shaft. There is a section of a light rod portion 31 at the position of the axial hole of the pivoting portion 21 in the middle of the rotating shaft 30; the two ends of the rotating shaft 30 are penetrated through the left ear plate 11 and the axial hole of the right ear plate 12 and can only make axial movement relative to the left ear plate 11 and the right ear plate 12 but not circumferential movement. A return spring 40 is installed between the rotating shaft 30 and the left ear plate 11 or the right ear plate 12. Under the elastic force of the return spring 40, the external spline in the middle of the rotating shaft 30 and the internal spline 22 in the middle of the axial hole of the pivot part 21 are in a meshing state. When pressing force or pulling force is applied to the rotating shaft 30 to overcome the elastic force of the return spring 40 and move in the reverse direction, the bare rod portion 31 of the rotating shaft 30 corresponds to the internal spline 22 of the pivot part 21. At this time, the pivot part 21 can rotate around the rotating shaft 30.

[0052] like Fig. 9 , 10 As shown, the shaft holes of the left ear plate 11 and the right ear plate 12 are stepped holes with a smaller inner side and a larger outer side, a nut 32 protruding from the left ear plate 11 is installed at the left end of the rotating shaft 30, an annular baffle 90 and a retaining ring 50 are installed at the right end of the rotating shaft 30, an end cover 60 is installed on the outer side of the shaft hole of the right ear plate 12, a reset spring 40 is installed between the retaining ring 50 and the step surface of the shaft hole of the right ear plate 12 or between the nut 32 and the step surface of the shaft hole of the left ear plate 11, and a locking mechanism 100 is provided at the position of the outer section of the shaft hole of the right ear plate 12, and the locking mechanism 100 can prevent the shaft 30 from resetting by cooperating with the annular baffle 90.

The right side of the annular baffle 90 is provided with a conical surface. When the rotating shaft 30 moves to the right, the conical surface of the annular baffle 90 can cooperate with the inclined surface on the locking pin 101, thereby applying a downward pressure to the locking pin 101, pressing the end of the locking pin 101 into the radial through hole. After the annular baffle 90 passes through the radial through hole, the end of the locking pin 101 quickly rebounds into the shaft hole of the right ear plate 12 under the action of the elastic force of the spring. At this time, the end of the locking pin 101 just blocks the annular baffle 90 from the left side, thereby locking the axial position of the rotating shaft 30. At this time, the blocking of the annular baffle 90 by the locking pin 101 can only be released by pushing the toggle block 102 downward by hand to drive the locking pin 101 to move downward.

When the pivoting part 21 rotates relative to the rotating shaft 30, the positioning pin 11a encounters the arc-shaped shallow grooves a on the left end surface of the pivoting part 21 under the action of the spring, and a "click" impact sound is emitted, thereby playing a prompting role.

[0055] like Fig. 9 , 10 As shown, a groove 14 is provided downwardly in the middle of the U-shaped portion to separate the two ear plates, and a screw hole is provided perpendicularly to the groove 14, in which an adjustment screw 70 is installed. This structure can facilitate the adjustment of the spacing between the two ear plates.

[0056] The working principle and operation description of the present invention are as follows:

[0057] 1) In the default state of the rotating shaft mechanism, due to the elastic force of the return spring 40, the external spline of the rotating shaft 30 and the internal spline 22 in the middle of the shaft hole of the pivoting part 21 are in a meshing state;

[0058] 2) Press or pull the shaft 30 by hand to make it move axially in the direction opposite to the spring force until the bare rod portion 31 in the middle of the shaft 30 corresponds to the internal spline 22 in the middle of the shaft hole of the pivoting portion 21;

[0059] 3) Move the upper flap 20 to rotate around the rotating shaft 30, so that the angle between the upper flap 20 and the base plate 10 reaches the required angle, and then release the intervening force on the rotating shaft 30, and the rotating shaft 30 returns to its original position under the elastic force of the return spring 40, so that the rotating shaft mechanism returns to the locked state;

[0060] 4) Rotate the quick-release plate coupling member 80 to a desired angle, and then fix the quick-release plate coupling member 80 at the angle using a manual locking member.

[0061] In this embodiment, since the upper flip plate 20 can make a flipping movement of 0° to 90° relative to the base plate 10 through a lockable rotating shaft mechanism, the camera can be used to shoot between 0° and 90°. When the upper flip plate 20 is fixed at a 90° position, the quick-release plate connecting part 80 on the upper flip plate 20 can be horizontally rotated relative to the upper flip plate 20, so that the camera can be used to shoot vertically upward or vertically downward.
