[0040] The detailed description and technical contents of the present invention will be described as follows with reference to the drawings. However, the drawings are only for illustration purposes and are not intended to limit the present invention.

[0041] The present invention provides a pan / tilt structure for carrying a photographing device A and being fixed on a tripod B. In this embodiment, the photographing device A is a camera and includes a camera body A1 and a camera lens A2, but the present invention is not limited thereto. Figures 1 to 3 FIG. 1 is a first embodiment of the pan / tilt structure of the present invention, which mainly includes a fixing frame 10 , a rotating seat 30 , a pressing member 40 and an adjusting component 50 .

[0042] The fixing frame 10 includes a first clamping plate 11, an adapter plate 12, and a second clamping plate 20 which are vertically connected and positioned corresponding to the first clamping plate 11. Specifically, the adapter plate 12 in this embodiment is horizontally arranged, and the first clamping plate 11 is vertically arranged on one side of the adapter plate 12, but the present invention is not limited thereto. The adapter plate 12 is used to be installed on the tripod B to fix the pan / tilt structure of the present invention. In this embodiment, the adapter plate 12 is rectangular, but the present invention is not limited thereto, and the shape of the adapter plate 12 can be adjusted accordingly according to the installation interface of different tripods B. The first clamping plate 11 has a first arc-shaped clamping groove 111 and a plurality of positioning holes 112. Specifically, the first arc-shaped clamping groove 111 is arc-shaped and is arranged at the top edge of the front side of the first clamping plate 11, and each positioning hole 112 vertically penetrates the two opposite side surfaces of the first clamping plate 11.

[0043] The second clamping plate 20 has a plurality of studs 21. Each stud 21 extends from the rear side of the second clamping plate 20 and is inserted into each positioning hole 112 from the front side of the first clamping plate 11, so that the two can play a positioning effect. In this embodiment, the pan / tilt structure of the present invention also includes a plurality of bolts 60, each bolt 60 is respectively inserted into each positioning hole 112 from the rear side of the first clamping plate 11 and is screwed and fixed to each stud 21 to prevent the second clamping plate 20 from detaching, but the present invention is not limited to this. The second clamping plate 20 has a second arc-shaped clamping groove 22. Specifically, the second arc-shaped clamping groove 22 corresponds to the first arc-shaped clamping groove 111 and is also arc-shaped, and is arranged at the top edge of the rear side of the second clamping plate 20, so that the first arc-shaped clamping groove 111 and the second arc-shaped clamping groove 22 are symmetrically arranged relative to each other.

[0044] The rotating base 30 includes a mounting platform 31 and a slide rail 32. The mounting platform 31 is used to mount the camera body A1 of the photographing device A. Specifically, the mounting platform 31 is vertically penetrated with a long hole 311 for a bolt 60 to pass through and lock with the photographing device A, thereby fixing the photographing device A on the mounting platform 31. The slide rail 32 is vertically connected to the front end of the mounting platform 31, that is, the plane formed by the sliding track of the slide rail 32 is perpendicular to the mounting platform 31, so that the camera lens A2 of the photographing device A is fixed by the slide rail 32. Please refer to Figure 4 As shown, in this embodiment, a plurality of bolts 60 are passed through the slide rail 32 and the mounting portion 324 described later is locked on the front side of the mounting platform 31, thereby fixing the slide rail 32 to the mounting platform 31. A portion of the slide rail 32 is located between the first arc-shaped clamping groove 111 and the second arc-shaped clamping groove 22, so that the rotating seat 30 is disposed on the fixing frame 10.

[0045] In this embodiment, the slide rail 32 is annular, but the present invention is not limited thereto. For example, the slide rail 32 may also be arc-shaped. Fig.10 FIG. 2 is a second embodiment of the present invention. The main difference between the second embodiment and the first embodiment is that the slide rail 32 is in the shape of a three-quarter circle arc. Fig.11 FIG. 3 is a third embodiment of the present invention, which is different from the first embodiment in that the slide rail 32 is in the shape of a semicircular arc. Thus, the shape of the slide rail 32 can be selected according to the requirements of different rotation angles. It should be noted that the shape of the slide rail 32 mentioned above is only an example for explanation and is not intended to limit the shape of the slide rail 32 of the present invention. Therefore, as long as the slide rail 32 is in the shape of a circular ring or an arc, it should fall within the protection scope of the present invention.

[0046] The pressing member 40 is a first clamping plate 11 and a second clamping plate 20 that penetrate the fixing frame 10. The adjusting assembly 50 is disposed on the second clamping plate 20 and connected to the pressing member 40. The adjusting assembly 50 can be switched between an unlocking position and a locking position, so that the pressing member 40 can loosen or tighten the first clamping plate 11 and the second clamping plate 20 of the fixing frame 10, thereby allowing the slide rail 32 to slide between the first arc-shaped clamping groove 111 and the second arc-shaped clamping groove 22 or be clamped and fastened between the first arc-shaped clamping groove 111 and the second arc-shaped clamping groove 22, thereby achieving the effect of simply and quickly rotating the rotating seat 30 at multiple angles.

[0047] Specifically, see Figure 6 and Figure 7 As shown, when the adjustment assembly 50 is in the unlocked position, the pressing member 40 releases the pressing force on the first clamping plate 11 and the second clamping plate 20, so that the slide rail 32 can slide in the gap between the first arc-shaped clamping groove 111 and the second arc-shaped clamping groove 22 to adjust the angle of the rotating seat 30. Figure 3 and Figure 5 As shown, when the adjustment component 50 is in the locking position, the pressing member 40 presses the first clamping plate 11 and the second clamping plate 20 of the fixing frame 10, thereby clamping and fixing the slide rail 32 between the first arc-shaped clamping groove 111 and the second arc-shaped clamping groove 22 to fix the rotating seat 30. Accordingly, the pan / tilt structure of the present invention can quickly adjust the fixed angle of the rotating seat 30 through the cooperation between the adjustment component 50 and the pressing member 40, so that the rotating seat 30 can be rotated and fixed at the desired angle according to different needs for the user to take pictures. Please refer to Figure 8 and Fig. 9 , which is a schematic diagram of the rotating base 30 before and after rotating 90 degrees, but the rotation angle of the pan / tilt structure of the present invention is not limited to the disclosed figure.

[0048] For further explanation, see Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, the slide rail 32 includes a main body 321, a connecting portion 322, a limiting portion 323 and a mounting portion 324. The main body 321 in this embodiment is annular. The connecting portion 322 extends vertically from a portion of the outer edge of the main body 321 and connects to the limiting portion 323. Figure 5 and Figure 7 The cross-sectional width of the middle connecting portion 322 is smaller than the cross-sectional width of the main body portion 321. The limiting portion 323 gradually extends outward from the end of the connecting portion 322. Figure 5 and Figure 7The cross section of the middle limiting portion 323 is roughly trapezoidal. The shapes of the first arc-shaped clamping groove 111 and the second arc-shaped clamping groove 22 correspond to the outer shape configuration of the connecting portion 322 and the limiting portion 323, so that the first arc-shaped clamping groove 111 and the second arc-shaped clamping groove 22 can clamp the slide rail 32 together. The mounting portion 324 extends from the rear side of the main body portion 321 and is roughly in an inverted L shape, so as to be installed and fixed at the front end of the mounting platform 31.

[0049] See also Figures 2 to 7 As shown, the adjustment component 50 in this embodiment includes a knob 51, a sleeve 52 and a positioning pin 53. The knob 51 is connected and fixed to one end of the sleeve 52. The sleeve 52 has a notch 521 and a blind hole 522 that are connected to each other. Specifically, the blind hole 522 extends inward from the end surface of the other end of the sleeve 52 and is eccentrically arranged with the sleeve 52, that is, the center of the blind hole 522 and the center of the sleeve 52 are located at different positions, and the notch 521 extends inward from the side edge of the sleeve 52 to connect with the blind hole 522. The positioning pin 53 is stuck in the blind hole 522, and the side edge of the positioning pin 53 has a screw hole 531 corresponding to the position of the notch 521. Accordingly, when the knob 51 is turned, the sleeve 52 can be driven to rotate, thereby driving the positioning pin 53 in the sleeve 52 to rotate together.

[0050] Furthermore, the first clamping plate 11 has a first through slot 113, and the second clamping plate 20 has a receiving slot 23 and a second through slot 24 that are connected to each other. Specifically, the first through slot 113 is a strip-shaped slot that longitudinally penetrates the first clamping plate 11 and extends in the vertical direction, the receiving slot 23 extends inward from the side wall of the second clamping plate 20, and the second through slot 24 extends inward from the rear side of the second clamping plate 20 and communicates with the receiving slot 23 and corresponds to the first through slot 113 and is also a strip-shaped slot. The sleeve 52 is rotatably inserted into the receiving slot 23, so that the knob 51 is exposed outside the second clamping plate 20. In this embodiment, the pressing member 40 is a shoulder bolt. The pressing member 40 is sequentially penetrated from the rear side of the first clamping plate 11 through the first through slot 113, the second through slot 24 and the notch 521, and is screwed and fixed to the screw hole 531 of the positioning pin 53.

[0051] By this, please refer to Figure 3 and Figure 5 As shown, when the adjustment assembly 50 is in the locked position, the positioning pin 53 and the first through slot 113 and the second through slot 24 are all located on the same horizontal line, so the pressing member 40 is in a horizontal state and presses the second clamping plate 20 toward the first clamping plate 11, so that the slide rail 32 is clamped and fixed between the first arc-shaped clamping groove 111 and the second arc-shaped clamping groove 22. Figure 6 and Figure 7As shown, when the knob 51 is rotated ninety degrees counterclockwise to place the adjustment assembly 50 in the unlocked position, since the positioning pin 53 and the sleeve 52 are eccentrically configured, the positioning pin 53 is transformed to be lower than the first through groove 113 and the second through groove 24, so that the pressing member 40 also rotates counterclockwise and tilts upward along the strip grooves of the first through groove 113 and the strip grooves of the second through groove 24, thereby loosening the clamping of the second clamping plate 20 and the first clamping plate 11, thereby allowing the slide rail 32 to slide in the gap between the first arc-shaped clamping groove 111 and the second arc-shaped clamping groove 22 to adjust the angle of the rotating seat 30.

[0052] Please read next Figures 12 to 17 , which is the fourth embodiment of the present invention, and the main difference between the fourth embodiment and the first embodiment is the composition of the adjustment assembly 50. Specifically, the adjustment assembly 50 in this embodiment includes a trigger 54 and a positioning pin 53. The trigger 54 has a cylindrical rotating portion 541. The rotating portion 541 has a notch 541A and a through hole 541B that are connected to each other. Specifically, the through hole 541B passes through both end surfaces of the rotating portion 541 and is eccentrically arranged with the rotating portion 541, that is, the center of the through hole 541B and the center of the rotating portion 541 are located at different positions, and the notch 541A extends inward from the side edge of the rotating portion 541 to connect with the through hole 541B. The positioning pin 53 is clamped in the through hole 541B, and the side edge of the positioning pin 53 has a screw hole 531 corresponding to the position of the notch 541A. Accordingly, when the trigger 54 is pulled, the rotating portion 541 can be driven to rotate, thereby driving the positioning pin 53 in the rotating portion 541 to rotate together.

[0053] In the present embodiment, the first clamping plate 11 has a first through slot 113, and the second clamping plate 20 has a receiving slot 23 and a second through slot 24 that are interconnected. Specifically, the first through slot 113 in the present embodiment is a strip-shaped slot that penetrates the first clamping plate 11 longitudinally and extends in the transverse direction, the receiving slot 23 extends inwardly from the front side of the second clamping plate 20, and the second through slot 24 extends inwardly from the rear side of the second clamping plate 20 and communicates with the receiving slot 23 and corresponds to the first through slot 113 and is also a strip-shaped slot. The rotating portion 541 is rotatably accommodated in the receiving slot 23, so that the trigger 54 is exposed outside the second clamping plate 20. In the present embodiment, the pressing member 40 is a shoulder bolt. The pressing member 40 is sequentially penetrated by the first through slot 113, the second through slot 24 and the notch 541A from the rear side of the first clamping plate 11, and is screwed and fixed to the screw hole 531 of the positioning pin 53.

[0054] By this, please refer to Figure 12 to Figure 14As shown, when the adjustment assembly 50 is in the locked position, the trigger 54 is flat against the front side of the first clamping plate 11, and the positioning pin 53, the first through slot 113 and the second through slot 24 are all located on the same horizontal line, so the pressing member 40 is in a horizontal state and presses the second clamping plate 20 toward the first clamping plate 11, so that the slide rail 32 is clamped and fixed between the first arc-shaped clamping groove 111 and the second arc-shaped clamping groove 22. Figures 15 to 17 As shown, when the trigger 54 is moved forward ninety degrees to place the adjustment assembly 50 in the unlocked position, since the positioning pin 53 and the rotating portion 541 are eccentrically configured, the positioning pin 53 is driven by the rotating portion 541 to deflect laterally toward the first through groove 113 and the second through groove 24, so that the pressing member 40 also rotates with the positioning pin 53 and deflects laterally along the strip groove of the first through groove 113 and the strip groove of the second through groove 24, thereby loosening the clamping of the second clamping plate 20 and the first clamping plate 11, thereby allowing the slide rail 32 to slide in the gap between the first arc-shaped clamping groove 111 and the second arc-shaped clamping groove 22 to adjust the angle of the rotating seat 30.

[0055] Please refer to Figures 18 to 21 , which is the fifth embodiment of the present invention, and the main difference between the fifth embodiment and the first embodiment lies in the composition of the adjustment assembly 50. Specifically, the adjustment assembly 50 in this embodiment includes a handle 55, a fixing member 56, a baffle 57 and a compression spring 58. The handle 55 has a handle 551 and a cylindrical rotating portion 552. The two end surfaces of the rotating portion 552 respectively have a blind hole 552A and a groove 552B that are opposite and communicated with each other. Specifically, the blind hole 552A extends inwardly from the rear end surface of the rotating portion 552, and the groove 552B extends inwardly from the front end surface of the rotating portion 552, and the blind hole 552A and the groove 552B are connected via a through hole 552C therebetween. The handle 551 is disposed on the front end surface of the rotating portion 552, thereby shielding the groove 552B.

[0056] In this embodiment, the first clamping plate 11 has a locking hole 114, and the second clamping plate 20 has a receiving groove 23 and a second through groove 24 that are connected to each other. Specifically, the locking hole 114 in this embodiment is a threaded hole that longitudinally penetrates the first clamping plate 11, the receiving groove 23 extends inward from the front side of the second clamping plate 20, and the second through groove 24 extends inward from the rear side of the second clamping plate 20 to connect with the receiving groove 23. The position and size of the second through groove 24 correspond to the position and size of the locking hole 114 and is a circular hole, and the diameter of the second through groove 24 is smaller than the diameter of the receiving groove 23, such as Fig.19 and Fig.21 The rotating portion 552 is partially rotatably disposed in the receiving groove 23 , so that the rotating handle 55 is exposed outside the second clamping plate 20 .

[0057] In this embodiment, the pressing member 40 is generally rod-shaped and includes a sleeve section 41, a supporting section 42 and a screw section 43 connected in sequence, wherein the diameter of the supporting section 42 is larger than that of the sleeve section 41 or the screw section 43. The two end surfaces of the supporting section 42 are respectively in contact with the bottom of the blind hole 552A and the bottom of the receiving groove 23, so that the sleeve section 41 passes through the clamping through hole 552C and is accommodated in the groove 552B. Accordingly, when the handle 55 is rotated, the handle 551 can drive the rotating part 552 to rotate, thereby driving the pressing member 40 clamped in the rotating part 552 to rotate together. The fixing member 56 is used to fix the baffle 57 to the sleeve section 41. The compression spring 58 is sleeved on the outer edge of the sleeve section 41 and elastically abuts between the bottom of the groove 552B and the baffle 57 in a pre-compressed manner. In this embodiment, the fixing member 56 is a screw, the baffle plate 57 is a gasket, and the sleeve section 41 is a stud, so that the screw is inserted through the gasket and then locked in the stud, but the present invention is not limited to this. For example, the fixing member 56 can also be a rivet, and the sleeve section 41 is a hollow cylinder. Therefore, the sleeve section 41, the fixing member 56, the baffle plate 57 and the compression spring 58 are all accommodated in the groove 552B of the rotating part 552. The screw section 43 penetrates the second through groove 24 and is screwed to the lock hole 114. It should be noted that the screw section 43 is only provided with external threads at the portion screwed to the lock hole 114, and no external threads are provided at the portion penetrating the second through groove 24.

[0058] By this, please refer to Fig.18 and Fig.19 As shown, when the adjustment assembly 50 is in the locked position, the abutting section 42 abuts against the bottom of the receiving groove 23, so that the screw section 43 of the pressing member 40 presses the second clamping plate 20 toward the first clamping plate 11 through the lock hole 114, so that the slide rail 32 is clamped and fixed between the first arc-shaped clamping groove 111 and the second arc-shaped clamping groove 22. Fig. 20 and Fig.21 As shown, when the handle 55 is rotated counterclockwise about forty-five degrees to place the adjustment assembly 50 in the unlocked position, the pressing member 40 is driven by the rotating portion 552 to rotate forward together, so that a portion of the threaded section 43 is disengaged from the threaded connection with the lock hole 114, thereby loosening the tightening of the second clamping plate 20 and the first clamping plate 11, thereby allowing the slide rail 32 to slide in the gap between the first arc-shaped clamping groove 111 and the second arc-shaped clamping groove 22 to adjust the angle of the rotating seat 30.

[0059] It should be noted that by pre-compressing the compression spring 58 to elastically push the baffle 57, the pressing member 40 will be subjected to a forward pulling force when the adjustment assembly 50 is in the unlocked position or the locked position, and the external thread of the threaded section 43 and the locking hole 114 will not be loosened, thereby effectively ensuring the stability and reliability of the pressing member 40, thereby preventing the rotating seat 30 from sliding due to the influence of gravity.

[0060] The above-described embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or changes made by those skilled in the art based on the present invention are within the protection scope of the present invention. The protection scope of the present invention shall be subject to the claims.
