In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "setting", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] According to the first embodiment of the present invention, the flip bracket Figure 1 , Figure 2 , Figure 3, including: a main shaft 100, the main shaft 100 is arranged along the left and right directions; a first frame 200, the first frame 200 is sleeved on the left side of the main shaft 100, the main shaft 100 is suitable for moving left and right relative to the first frame 200 and for rotating synchronously with the first frame 200. In this embodiment, the function of the first frame 200 is to install and fix the entire flip bracket; a second frame 300, the second frame 300 is rotatably arranged on the right side of the main shaft 100, and the right end of the second frame 300 is provided with a plurality of slots 301 along the circumferential direction, and the notch of the slot 301 is arranged to the right, wherein the second frame 30 0 is sleeved on the main shaft 100, and the slots 301 are evenly distributed on the second frame 300 along the circumference of the main shaft 100. In this embodiment, the second frame 300 is used to install the lens barrel. The second frame 300 rotates relative to the main shaft 100 and the first frame 200 to achieve the angle adjustment of the lens barrel; the first pin 400 is vertically arranged on the main shaft 100 and accommodated in the slot 301. The main shaft 100 is provided with a plug hole in the radial direction. The first pin 400 is inserted in the plug hole, and the other end is arranged toward the slot 301 and can abut against the inner wall of the slot 301. The elastic member 500 is suitable for driving the main shaft 100 to move toward the direction of the first frame 200.

[0028] When the second frame 300 rotates around the main shaft 100, the slot 301 and the first pin 400 abut against each other, and the slot 301 rotates relative to the first pin 400. The contact force between the slot 301 and the first pin 400 drives the first pin 400 and the main shaft 100 to move rightward together to overcome the elastic force of the elastic member 500. At the same time, the first pin 400 disengages from the slot 301 and abuts against the second frame 300 under the elastic force of the elastic member 500. When the second frame 300 rotates to a certain angle, the next slot 301 adjacent to the first slot 301 rotates to the position of the first pin 400, and the first pin 400 contacts the next adjacent slot 301. Under the action of the elastic member 500, the first pin 400 and the main shaft 100 move leftward and place the first pin 400 in the next slot 301, completing an angular rotation of the second frame 300, thereby driving the lens barrel to achieve a fixed angular rotation. 301 , the second frame 300 is rotated. At the same time, in order to push the first pin 400 out of the slot 301, it is necessary to apply a greater force to the second frame 300 through external force. Therefore, during the human rotation process, the force of rotating the second frame 300 can be used to sense whether the first pin 400 is accommodated in the slot 301. In the above description, "a certain angle" refers to the angle between two adjacent slots 301. Therefore, it can be understood that during one rotation process, the rotation angle of the second frame 300 is equal to the angle between two adjacent slots 301. That is to say, the rotation angle in each rotation process can be controlled by setting the angle between the slots 301. The angle can be 30°, 45°, 60°, etc. The number of slots 301 can also be 12 groups, 8 groups, or 6 groups corresponding to the angle. The angle value between the slots 301 and the number of slots 301 can be set separately according to the actual angle adjustment needs, and the present invention does not make specific restrictions.

[0029] The flip bracket according to the embodiment of the present invention has at least the following beneficial effects: the present invention utilizes the rotation of the second frame to drive the first pin to disengage from the slot. After the first pin disengages from the slot, the second frame continues to rotate to a certain angle, and the first pin is driven by the elastic member to cooperate with the next slot on the second frame, thereby realizing the control of the rotation angle. The present invention has high positioning accuracy and accurate rotation angle, and can achieve fixed angle adjustment by manpower without the need for additional angle measuring equipment, which greatly saves equipment costs and simplifies the operating procedures during the flipping process.

[0030] In some embodiments of the present invention, reference Figure 1 , Figure 2The first frame 200 includes: a sleeve 210, the inner diameter of which is compatible with the main shaft 100 and is sleeved on the left end of the main shaft 100; a fixed seat 220, one side of the fixed seat 220 is sleeved on the sleeve 210 and fixed to the sleeve 210 by bolts, and the other side is provided with a fixing structure 221 suitable for connecting to the outside. In this embodiment, the fixing structure 221 is a downward-opening groove structure, which can be fixed to a matching slide rail through the groove structure. In addition, the fixing structure 221 can also be other mounting structures 321 such as bolt holes and bolts. The function of the first frame 200 is to fix the flip bracket through the fixed seat 220, and use the sleeve 210 structure to meet the connection with the main shaft 100, so as to ensure the stability and compactness of the flip bracket structure.

[0031] Preferably, reference Figure 2 , Figure 4 , and also includes a second pin 600. The main shaft 100 is provided with a slide groove 101 along the axial direction.

The second pin 600 is cylindrical, and the diameter of the second pin 600 is adapted to the groove width of the slide groove 101. A pin hole 212 is radially provided on the sleeve 210. The second pin 600 is vertically arranged, one end of which is arranged in the pin hole 212, and the other end is inserted in the slide groove 101 and simultaneously abuts against the two side walls of the slide groove 101. By setting the second pin 600 and the slide groove 101 structure, when the main shaft 100 rotates, the second pin 600 abuts against the inner wall of the slide groove 101, thereby driving the first frame 200 to rotate synchronously, ensuring that the first frame 200 and the main shaft 100 are relatively fixed in the circumferential direction. At the same time, when the main shaft 100 moves left and right along the axial direction, the second pin 600 slides relative to the slide groove 101, thereby ensuring that the main shaft 100 can move flexibly within a certain range. The slide groove 101 also has a limiting function. The aforementioned "certain range" is equivalent to the length of the slide groove 101, which can limit the moving distance of the main shaft 100 in the left and right directions by cooperating with the second pin 600 to prevent the main shaft 100 from separating from the sleeve 210.

[0032] It should be noted that the function of the second pin is to ensure the synchronous rotation of the first bracket and the main shaft, and at the same time ensure that the main shaft can move axially relative to the first bracket. The assembly method of the second pin is not limited to the method proposed in the above embodiment. It can also be that a pin hole is provided radially on the main shaft, and a slide groove is provided axially on the inner side of the sleeve. One end of the second pin is adapted to the pin hole and inserted in the pin hole, and the diameter of the other end is adapted to the width of the slide groove and is inserted in the slide groove, thereby realizing the assembly connection of the second pin.

The right end of the sleeve 310 extends toward the outside of the sleeve 210, and the slots 301 are evenly arranged at the right end of the sleeve 310 along the circumference of the sleeve 310; a mounting seat 320, one side of the mounting seat 320 is sleeved on the sleeve 310 and connected to the sleeve 310 by a locking bolt, and the other side is provided with a mounting structure 321 suitable for installing an external device. In this embodiment, the external device is a lens barrel, and the mounting structure 321 includes a rectangular mounting plate and a bolt member arranged on the rectangular mounting plate. The fixed assembly is achieved by fitting the rectangular mounting plate to the side of the lens barrel and connecting the rectangular mounting plate and the lens barrel by the bolt member.

[0034] Preferably, reference Figure 2 , Figure 4 , further comprising a third pin 700, the sleeve 210 is provided with a positioning groove 211 along the circumferential direction, the groove width of the positioning groove 211 is adapted to the diameter of the third pin 700, the sleeve 310 is provided with a positioning hole 311 adapted to the third pin 700 along the radial direction, one end of the third pin 700 is inserted into the positioning hole 311, and the other end is inserted into the positioning groove 211 and abuts against the left and right side walls of the positioning groove 211. In this embodiment, the second frame 300 drives the sleeve 210 to rotate together, the third pin 700 and the limiting groove ensure the rotation trajectory of the sleeve 210, and at the same time prevent the sleeve 210 from being separated from the sleeve 310, ensuring that the sleeve 210 and the sleeve 310 are relatively fixed in the axial direction.

[0035] It should be noted that the function of the third pin is to ensure the rotation of the sleeve relative to the sleeve and at the same time ensure the axial fixation of the sleeve and the sleeve. The assembly method of the third pin is not limited to the assembly method in the above embodiment. It can also be that a positioning groove is provided along the circumferential direction on the inner side of the sleeve, and a positioning hole is provided along the radial direction on the sleeve. One end of the third pin is inserted into the positioning hole, and the other end extends toward the positioning groove to realize assembly.

[0036] At the same time, the connection method between the sleeve and the bushing is also not limited to the connection method through the third pin disclosed in the above embodiment. It can also be that a positioning protrusion is provided on the inner side of the sleeve along the circumferential direction, and a positioning groove is provided on the outer side of the sleeve along the circumferential direction. The positioning protrusion is clamped in the positioning groove to realize the assembly of the sleeve and the bushing.

[0037] In some embodiments of the present invention, reference Figure 3 There are four groups of card slots 301 along the circumference of the sleeve 310, and the angle between two adjacent groups of card slots 301 is 90°. In this embodiment, by setting four groups of card slots 301, the rotation angle of the second frame 300 during each flipping process is controlled to be 90°, thereby achieving precise control of the flipping angle.

[0039] In some embodiments of the present invention, reference Figure 3 The slot 301 is a V-shaped slot, the opening of the slot 301 faces right, and the groove surface of the V-shaped slot is an inclined structure. During the rotation of the sleeve 310, the force applied to the first pin 400 can be converted into a horizontal thrust by the groove surface of the inclined structure, thereby pushing the first pin 400 out of the slot 301, which has the advantages of ensuring the flexible operation of the flip bracket and reducing the resistance during the flipping process.

[0040] It should be noted that the structural feature of the slot is that the rotating force of the slot is converted into a thrust on the first pin through the inclined slot surface. Its specific structure is not limited to the V-shaped slot structure in this embodiment, but can also be a semicircular slot, trapezoidal groove or other slot structures with an inclined slot surface.
