[0041] The detailed description and technical contents of this application will be described below with reference to the accompanying drawings. However, the accompanying drawings are for illustrative purposes only and are not intended to limit this application.

[0042] This application provides a pan / tilt structure for supporting a camera device A and capable of being secured to a tripod B. In this embodiment, the camera device A is a camera comprising a camera body A1 and a camera lens A2, but this application is not limited thereto. Referring to Figures 1 to 3 , a first embodiment of the pan / tilt structure of this application is shown, which primarily comprises a fixing frame 10, a rotating base 30, a pressing member 40, and an adjustment assembly 50.

[0043] The fixing frame 10 includes a first clamping plate 11, an adapter plate 12, and a second clamping plate 20 positioned corresponding to the first clamping plate 11, which are vertically connected. 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 application is not limited to this. The adapter plate 12 is used to be installed on the tripod B to fix the pan / tilt structure of the present application. In this embodiment, the adapter plate 12 is rectangular, but the present application is not limited to this. 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 longitudinally passes through the two opposite side surfaces of the first clamping plate 11.

[0044] 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 application 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 application 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.

[0045] 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 camera device A. Specifically, a vertically extending elongated hole 311 is provided through the mounting platform 31 for a bolt 60 to pass through and lock with the camera device A, thereby securing the camera device A to the mounting platform 31. The slide rail 32 is vertically connected to the front end of the mounting platform 31. Specifically, the plane formed by the sliding path of the slide rail 32 is perpendicular to the mounting platform 31, thereby securing the camera lens A2 of the camera device A via the slide rail 32. Referring to Figure 4, in this embodiment, a plurality of bolts 60 are passed through the mounting portion 324 of the slide rail 32, described below, and locked to the front side of the mounting platform 31, thereby securing the slide rail 32 to the mounting platform 31. A portion of the slide rail 32 is located between the first arcuate clamping groove 111 and the second arcuate clamping groove 22, thereby securing the rotating base 30 to the fixed frame 10.

[0046] In the present embodiment, the slide rail 32 is in the shape of a circular ring, but the present application is not limited thereto. For example, the slide rail 32 may also be in the shape of an arc. Please refer to FIG10 , which is the second embodiment of the present application. The main difference between the slide rail 32 and the first embodiment is that the slide rail 32 is in the shape of a three-quarter circle arc. Please refer to FIG11 , which is the third embodiment of the present application. The main difference between the slide rail 32 and the first embodiment is that the slide rail 32 is in the shape of a semicircle arc. In this way, 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 used to limit the shape of the slide rail 32 of the present application. Therefore, as long as the slide rail 32 is in the shape of a circular ring or an arc, it should fall within the scope of protection of the present application.

[0047] The pressing member 40 is connected to the first clamping plate 11 and the second clamping plate 20 of 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 unlocked position and a locked position, thereby causing the pressing member 40 to loosen or tighten the first clamping plate 11 and the second clamping plate 20 of the fixing frame 10. This allows the slide rail 32 to slide or be clamped between the first and second arcuate clamping grooves 111 and 22, thereby achieving the purpose of easily and quickly adjusting the rotating base 30 to various angles.

[0048] Specifically, referring to Figures 6 and 7 , when the adjustment assembly 50 is in the unlocked position, the pressing member 40 releases the tension between the first clamping plate 11 and the second clamping plate 20, allowing the slide rail 32 to slide in the gap between the first and second arcuate clamping grooves 111 and 22 to adjust the angle of the swivel base 30. Referring again to Figures 3 and 5 , when the adjustment assembly 50 is in the locked position, the pressing member 40 tightens the first and second clamping plates 11 and 20 of the mounting frame 10, thereby clamping the slide rail 32 between the first and second arcuate clamping grooves 111 and 22, thereby securing the swivel base 30. Thus, the pan / tilt structure of the present application enables the use of the adjustment assembly 50 and the pressing member 40 to quickly adjust the fixed angle of the swivel base 30, allowing the swivel base 30 to be rotated and secured at a desired angle according to different needs for filming. Please refer to FIG. 8 and FIG. 9 , which are schematic diagrams of the rotating base 30 before and after rotating 90 degrees. However, the rotation angle of the pan / tilt structure of the present application is not limited to the diagrams.

[0049] For further explanation, referring again to Figures 2, 3, 5 and 7, 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, that is, the cross-sectional width of the connecting portion 322 in Figures 5 and 7 is smaller than the cross-sectional width of the main body 321. The limiting portion 323 gradually extends outward from the end of the connecting portion 322, that is, the cross-sectional shape of the limiting portion 323 in Figures 5 and 7 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 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 jointly clamp the slide rail 32. The mounting portion 324 extends from the rear side of the main body 321 and is approximately in an inverted L-shape for mounting and fixing the front end of the mounting platform 31 .

[0050] Referring again to Figures 2 to 7 , the adjustment assembly 50 in this embodiment includes a knob 51, a sleeve 52, and a locating pin 53. The knob 51 is fixedly connected to one end of the sleeve 52. The sleeve 52 has a notch 521 and a blind hole 522 that are interconnected. Specifically, the blind hole 522 extends inward from the end surface of the other end of the sleeve 52 and is eccentrically arranged with respect to the sleeve 52. That is, the center of the blind hole 522 is located at a different position from the center of the sleeve 52, and the notch 521 extends inward from the side edge of the sleeve 52 to connect with the blind hole 522. The locating pin 53 is fixed in the blind hole 522, and the side edge of the locating pin 53 has a screw hole 531 corresponding to the position of the notch 521. Accordingly, turning the knob 51 can drive the sleeve 52 to rotate, thereby driving the locating pin 53 in the sleeve 52 to rotate as well.

[0051] 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 interconnected. Specifically, the first through-slot 113 is a strip-shaped slot that extends longitudinally through the first clamping plate 11 and extends vertically. 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, connecting to the receiving slot 23 and corresponding to the first through-slot 113. It is also a strip-shaped slot. The sleeve 52 is rotatably inserted into the receiving slot 23, thereby exposing the knob 51 to the outside of 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 to the screw hole 531 of the positioning pin 53.

[0052] 3 and 5 , when the adjustment assembly 50 is in the locked position, the positioning pin 53 is located on the same horizontal line as the first through slot 113 and the second through slot 24 . Therefore, the pressing member 40 is in a horizontal state and presses the second clamping plate 20 toward the first clamping plate 11 , thereby clamping the slide rail 32 between the first arc-shaped clamping groove 111 and the second arc-shaped clamping groove 22 . 6 and 7 , when the knob 51 is rotated counterclockwise by ninety degrees to locate the adjustment assembly 50 in the unlocked position, the positioning pin 53 and the sleeve 52 are eccentrically arranged, so that the positioning pin 53 is transformed to be lower than the first through slot 113 and the second through slot 24 , so that the pressing member 40 also rotates counterclockwise and tilts upward along the strip groove of the first through slot 113 and the strip groove of the second through slot 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 .

[0053] Please refer to Figures 12 to 17, which are the fourth embodiment of the present application. The main difference between the fourth embodiment and the first embodiment lies in 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 interconnected. Specifically, the through-hole 541B passes through both end surfaces of the rotating portion 541 and is eccentrically arranged with respect to the rotating portion 541, that is, the center of the through-hole 541B is located at a different position from the center of the rotating portion 541, 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 fixed 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.

[0054] In this 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 this embodiment is a strip-shaped slot that longitudinally penetrates the first clamping plate 11 and extends transversely. The receiving slot 23 extends inward from the front side of the second clamping plate 20, and the second through-slot 24 extends inward from the rear side of the second clamping plate 20, connecting to the receiving slot 23 and corresponding to the first through-slot 113. It is also a strip-shaped slot. The rotating portion 541 is rotatably received in the receiving slot 23, thereby exposing the trigger 54 to the outside of 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 by the first through-slot 113, the second through-slot 24, and the notch 541A, and is screwed to the screw hole 531 of the positioning pin 53.

[0055] 12 to 14 , 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 is located on the same horizontal line as the first through slot 113 and the second through slot 24 . Therefore, the pressing member 40 is horizontal and presses the second clamping plate 20 toward the first clamping plate 11 , thereby clamping the slide rail 32 between the first arc-shaped clamping groove 111 and the second arc-shaped clamping groove 22 . Referring again to Figures 15 to 17, when the trigger 54 is turned forward 90 degrees to place the adjustment assembly 50 in the unlocked position, since the positioning pin 53 and the rotating portion 541 are eccentrically arranged, the positioning pin 53 is driven by the rotating portion 541 to deflect laterally toward the first through slot 113 and the second through slot 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 slot 113 and the strip groove of the second through slot 24, 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.

[0056] Please refer to Figures 18 to 21 , which illustrate the fifth embodiment of the present application. The primary difference between this 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 rotating portion 552 has two opposing, interconnected blind holes 552A and grooves 552B on its two end surfaces. Specifically, the blind hole 552A extends inward from the rear end of the rotating portion 552, while the groove 552B extends inward from the front end of the rotating portion 552. 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 of the rotating portion 552, thereby obscuring the groove 552B.

[0057] 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-slot 24 that communicate with each other. Specifically, the locking hole 114 in this embodiment is a threaded hole that extends longitudinally through 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-slot 24 extends inward from the rear side of the second clamping plate 20 and communicates with the receiving groove 23. The position and size of the second through-slot 24 correspond to the position and size of the locking hole 114 and is a circular hole. The diameter of the second through-slot 24 is smaller than that of the receiving groove 23, as shown in Figures 19 and 21. The rotating portion 552 is partially rotatably disposed within the receiving groove 23, thereby exposing the handle 55 to the outside of the second clamping plate 20.

[0058] In this embodiment, the pressing member 40 is generally rod-shaped and comprises a sleeve segment 41, a supporting segment 42, and a threaded segment 43, which are sequentially connected. The supporting segment 42 has a larger diameter than either the sleeve segment 41 or the threaded segment 43. The two end faces of the supporting segment 42 abut against the bottom of the blind hole 552A and the bottom of the receiving groove 23, respectively. This allows the sleeve segment 41 to pass through the securing hole 552C and be received within the recess 552B. Consequently, when the handle 55 is rotated, the handle 551 rotates the rotating portion 552, thereby rotating the pressing member 40 secured within the rotating portion 552. A fixing member 56 secures the baffle 57 to the sleeve segment 41. A compression spring 58 is mounted on the outer edge of the sleeve segment 41 and preloaded, elastically abuts between the bottom of the recess 552B and the baffle 57. In this embodiment, the fixing member 56 is a screw, the baffle 57 is a washer, and the sleeve section 41 is a stud. The screw is inserted through the washer and then locked within the stud. However, this application is not limited to this embodiment. For example, the fixing member 56 may also be a rivet, and the sleeve section 41 may be a hollow cylinder. Therefore, the sleeve section 41, the fixing member 56, the baffle 57, and the compression spring 58 are all accommodated within the groove 552B of the rotating portion 552. The threaded section 43 passes through the second through-slot 24 and is threadedly connected to the locking hole 114. It should be noted that the threaded section 43 is externally threaded only in the portion that is threaded to the locking hole 114; the portion that passes through the second through-slot 24 is not externally threaded.

[0059] 18 and 19 , when the adjustment assembly 50 is in the locked position, the abutting section 42 abuts the bottom of the receiving groove 23, allowing the threaded section 43 of the pressing member 40 to tighten the second clamping plate 20 toward the first clamping plate 11 through the locking hole 114, thereby clamping the slide rail 32 between the first arcuate clamping groove 111 and the second arcuate clamping groove 22. Referring again to FIG20 and 21 , when the handle 55 is rotated counterclockwise approximately 45 degrees to unlock the adjustment assembly 50, the pressing member 40, driven by the rotating portion 552, rotates forward, causing a portion of the threaded section 43 to disengage from the locking hole 114, thereby loosening the tension between the second clamping plate 20 and the first clamping plate 11, allowing the slide rail 32 to slide in the gap between the first arcuate clamping groove 111 and the second arcuate clamping groove 22 to adjust the angle of the rotating base 30.

[0060] It should be noted that the compression spring 58 pre-loads and elastically pushes against the baffle 57, so that when the adjustment assembly 50 is in the unlocked position or the locked position, the pressing member 40 will be subjected to a forward pulling force, and the locking of the external thread of the threaded section 43 and the lock hole 114 will not be loosened. Therefore, the stability and reliability of the pressing member 40 are effectively ensured, thereby preventing the rotating base 30 from sliding due to the influence of gravity.

[0061] The above-described embodiments are merely preferred embodiments for the purpose of fully illustrating the present application, and the scope of protection of the present application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art based on the present application are within the scope of protection of the present application. The scope of protection of the present application shall be subject to the claims.
