Description

Technical Field

[0001] The utility model relates to a pan-tilt device and photographic equipment. Background Art

[0002] In photographic work, a photographic pan-tilt is often used to mount external devices such as cameras and video cameras. Generally, a mounting groove penetrating through both ends is provided on the photographic pan-tilt, and a quick-release plate for mounting external devices such as cameras and video cameras is detachably mounted in the mounting groove.

[0003] The quick-release plate is slidably fitted into the mounting groove along one end of the mounting groove, and then fixed by a locking block that can elastically extend and retract on the bottom surface of the mounting groove, so as to prevent the quick-release plate from easily falling out of the mounting groove when the camera or video camera is placed obliquely for shooting. Currently, the locking block protrudes vertically upward from the bottom surface of the mounting groove through a spring member, and sufficient height space needs to be reserved in the vertical direction according to the stroke of the locking block's telescopic movement and the requirements for mounting the spring member, resulting in a relatively large thickness dimension of this photographic pan-tilt, which is not conducive to carrying and using.

[0004] Moreover, since the spring member is arranged in the vertical direction, when the photographic pan-tilt is subjected to an impact or acceleration in the vertical direction, the locking block is likely to press downward on the spring member, causing the external device to fall off. Summary of the Utility Model

[0005] The utility model aims to at least solve one of the technical problems existing in the prior art. For this reason, one of the purposes of the utility model is to provide a pan-tilt device with a relatively small thickness dimension and the external device is not easily detached when being impacted; the second purpose is to provide a photographic equipment having the above pan-tilt device.

[0006] A pan-tilt device according to an embodiment of the first aspect of the utility model includes: a pan-tilt main body; a mounting groove provided on the pan-tilt main body, the mounting groove having an entrance for slidably fitting a quick-release plate, and a through hole is opened on the bottom surface of the mounting groove; a locking block rotatably provided on the pan-tilt main body through a rotating shaft, the locking block is connected with an elastic member that drives it to rotate to protrude from the through hole above the bottom surface of the mounting groove; an unlocking mechanism movably provided on the pan-tilt main body, which can drive the locking block to rotate to retract from the through hole below the bottom surface of the mounting groove.

[0007] A pan-tilt device according to an embodiment of the utility model has at least the following beneficial effects:

[0008] The locking block of the above gimbal device rotates around the rotating shaft under the action of the elastic member to extend from the through hole to the bottom surface of the mounting groove, thereby preventing the quick-release plate from sliding away from the gimbal body along the mounting groove, and the unlocking mechanism drives the locking block to rotate to retract from the through hole to below the bottom surface of the mounting groove to allow the quick-release plate to detach from the gimbal body; the movement stroke of the locking block rotating around the rotating shaft to extend from the through hole and retract into the through hole is short, so that the thickness of the gimbal device is greatly reduced, and when the external device is impacted, it will not directly act on the spring member, and it is not easy to cause the quick-release plate to fall off the gimbal body.

[0009] In some embodiments of the utility model, the rotating shaft is arranged horizontally, the locking block is formed on one side of the rotating shaft, a side protrusion is formed on the opposite side of the rotating shaft and the locking block, and both ends of the elastic member are abutted between the side protrusion and the gimbal body to drive the locking block to extend out of the through hole.

[0010] In some embodiments of the present invention, a receiving groove is provided at the bottom of the quick-release plate, and a driving slope is provided on the locking block. Along the direction in which the quick-release plate is inserted, at least a portion of the driving slope extends from bottom to top, and a locking surface connected to the upper end of the driving slope is provided at the front end of the locking block. The front end of the quick-release plate moves upward relative to the driving slope to drive the locking block to rotate until it retracts below the bottom surface of the installation groove. When the elastic member drives the locking block extending out of the perforated portion to enter the receiving groove, the locking surface is arranged opposite to the front side wall of the receiving groove.

[0011] In some embodiments of the present invention, the axial direction of the rotating shaft is parallel to the embedding direction of the quick-release plate, and the driving ramp surface is a spiral surface arranged around the axial circumference of the rotating shaft.

[0012] In some embodiments of the present invention, the locking surface is perpendicular to the axial direction of the rotating shaft.

[0013] In some embodiments of the present invention, the unlocking mechanism includes a movable part movably arranged on the gimbal body, the movable part abuts against the side protrusion and can move in the direction of compressing the elastic part, a through hole portion is opened on the side wall of the gimbal body, and the movable part has an operating component that movably extends out of the through hole portion.

[0014] In some embodiments of the utility model, the movable part is a swing arm whose one end is rotatably connected to the gimbal body, and the other end of the swing arm is against the side of the side protrusion away from the elastic part, and the operating component is arranged on the side wall in the middle of the swing arm to rotate and retract in the through hole portion.

[0015] In some embodiments of the present utility model, the surface of the side convex portion facing away from the elastic member is a first plane, and a mating inclined surface is provided at one end of the swing arm that abuts against the side convex portion. When the locking block rotates to retract from the through hole below the bottom surface of the mounting groove, a surface-to-surface contact is formed between the first plane and the mating inclined surface.

[0016] In some embodiments of the present utility model, a second plane is provided on the upper surface of the locking block facing the swing arm, and the rotating shaft has a default portion where the second plane intersects the first plane. When the first plane abuts against the mating inclined surface, the second plane abuts against the upper surface of the swing arm.

[0017] The photographic equipment according to the second aspect embodiment of the present utility model includes a pan-tilt device as described in any of the above technical solutions. Since the movement stroke of the locking block rotating around the rotating shaft to extend out of and retract into the through hole is relatively short, the thickness dimension of the pan-tilt device of the photographic equipment is small, and it is not easy for the quick-release plate to fall off the pan-tilt body when the external device is impacted, which is beneficial to the stability of photographic work.

[0032] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "mounting", "connecting", "coupling" 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 directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0033] SeeFigures 1 to 5 The utility model is a pan-tilt device, comprising: a pan-tilt body 100; a mounting groove 110, which is arranged on the pan-tilt body 100, the mounting groove 110 having an entrance for a quick-release plate 200 to be slidably installed, and a through hole 120 is provided on the bottom surface of the mounting groove 110; a locking block 300, which is rotatably arranged on the pan-tilt body 100 via a rotating shaft 310, and the locking block 300 is connected to an elastic member 400 that drives it to rotate until it extends from the through hole 120 to above the bottom surface of the mounting groove 110; an unlocking mechanism, which is movably arranged on the pan-tilt body 100 and can drive the locking block 300 to rotate until it retracts from the through hole 120 to below the bottom surface of the mounting groove 110.

[0034] The locking block 300 of the above gimbal device rotates around the rotating shaft 310 under the action of the elastic member 400 to extend from the through hole 120 to the bottom surface of the mounting groove 110, thereby preventing the quick-release plate 200 from sliding away from the gimbal body 100 along the mounting groove 110, and the unlocking mechanism drives the locking block 300 to rotate to retract from the through hole 120 to below the bottom surface of the mounting groove 110 to allow the quick-release plate 200 to detach from the gimbal body 100; the movement stroke of the locking block 300 rotating around the rotating shaft 310 to extend from the through hole 120 and retract into the through hole 120 is relatively short, so that the thickness of the gimbal device is greatly reduced, and when the external device is subjected to an impact in a certain linear direction, it will not directly act on the spring member, and it is not easy to cause the quick-release plate 200 to fall off from the gimbal body 100.

[0035] See also Figure 2 , Figure 6 and Figure 7 In some embodiments of the utility model, the rotating shaft 310 is arranged horizontally, the locking block 300 is formed on one side of the rotating shaft 310, and a side protrusion 320 is formed on the side opposite to the rotating shaft 310 and the locking block 300, and both ends of the elastic member 400 abut between the side protrusion 320 and the pan / tilt body 100 to drive the locking block 300 to extend from the through hole 120. It can be understood that the pan / tilt body 100 is correspondingly provided with an axial hole adapted to the rotating shaft 310, and the elastic member 400 acts on the side protrusion 320 to drive the rotating shaft 310 to rotate until the locking block 300 extends from the through hole 120. The elastic member 400 does not need to be arranged in the vertical direction, which is conducive to further reducing the thickness of the pan / tilt device. Of course, in other embodiments, the elastic member 400 can also be configured as a torsion spring member passing through the rotating shaft 310. In this case, there is no need to provide the side protrusion 320, and the two free ends of the torsion spring member respectively abut against the gimbal body 100 and the locking block 300.

[0036] See also Figures 3 to 7In some embodiments of the utility model, a receiving groove 210 is provided at the bottom of the quick-release plate 200, and a driving slope 330 is provided on the locking block 300. Along the insertion direction of the quick-release plate 200, at least part of the driving slope 330 extends from bottom to top. A locking surface 340 connected to the upper end of the driving slope 330 is provided at the front end of the locking block 300. The front end of the quick-release plate 200 moves upward relative to the driving slope 330 to drive the locking block 300 to rotate and retract below the bottom surface of the installation groove 110. When the elastic member 400 drives the portion of the locking block 300 extending out of the through hole 120 to enter the receiving groove 210, the locking surface 340 is arranged opposite to the front side wall of the receiving groove 210.

[0037] It can be understood that when the quick-release plate 200 is slidably installed from the entrance of the installation groove 110, the front end of the quick-release plate 200 first contacts the bottom end of the driving slope 330. As the quick-release plate 200 moves forward, the front end of the quick-release plate 200 moves upward along the driving slope 330, thereby driving the rotating shaft 310 to rotate until the locking block 300 retracts below the bottom surface of the installation groove 110. When the front end of the quick-release plate 200 passes over the driving slope 330 so that the locking block 300 can re-enter the receiving groove 210, the elastic member 400 drives the locking block 300 to rotate around the rotating shaft 310 until it partially extends out of the through hole 120. At this time, the locking surface 340 is opposite to the front side wall of the receiving groove 210 to prevent the quick-release plate 200 from retreating relative to the installation groove 110. When the quick-release plate 200 is slidably embedded in the installation groove 110, there is no need to use an unlocking mechanism, and the operation is very convenient. An unlocking mechanism is required to drive the locking block 300 to rotate until it is retracted from the through hole 120 to below the bottom surface of the mounting slot 110 so that the quick-release plate 200 can be withdrawn.

[0038] See also Figures 5 to 7 In some embodiments of the utility model, the axial direction of the rotating shaft 310 is parallel to the embedding direction of the quick-release plate 200, and the driving ramp 330 is a spiral surface arranged around the axial circumference of the rotating shaft 310. It should be noted that when the quick-release plate 200 moves forward in the installation slot 110, the angle between the front end of the quick-release plate 200 and the spiral surface remains basically unchanged. When the quick-release plate 200 moves forward by the same unit distance, the angular displacement of the rotating shaft 310 is basically the same, which is conducive to avoiding the quick-release plate 200 from getting stuck easily during the quick installation process, making the assembly of the pan / tilt device smoother.

[0039] See also Figure 5 and Figure 7In some embodiments of the present invention, the locking surface 340 is perpendicular to the axial direction of the rotating shaft 310. It can be understood that the locking surface 340 is located at the front end of the driving ramp surface 330 and is perpendicular to the axial direction of the rotating shaft 310. When the front end of the quick-release plate 200 passes over the driving ramp surface 330 so that the locking block 300 can enter the receiving groove 210, the locking surface 340 and the front side wall of the receiving groove 210 are arranged face to face. When the quick-release plate 200 has a tendency to move toward the entrance direction of the installation groove 110, the force of the locking surface 340 against the front side wall of the receiving groove 210 cannot form any component force to drive the rotating shaft 310 to rotate, thereby ensuring the reliability of the locking block 300 when locking the quick-release plate 200.

[0040] See also Figures 2 to 4 In some embodiments of the present invention, the unlocking mechanism includes a movable member 500 movably disposed on the platform body 100, the movable member 500 abuts against the side protrusion 320 and can move in the direction of compressing the elastic member 400, the side wall of the platform body 100 is provided with a through hole 130, and the movable member 500 has an operating member 510 that movably extends from the through hole 130. It should be noted that when the elastic member 400 drives the locking block 300 to extend from the through hole 120, the side protrusion 320 also acts on the movable member 500 to make the operating member 510 extend from the through hole 130, and at this time, force is applied to the operating member 510 to retract the operating member 510 from the through hole 130 to the inside of the platform body 100, and the movable member 500 can act on the side protrusion 320 to drive the rotating shaft 310 to rotate until the locking block 300 retracts from the through hole 120. The unlocking mechanism of this structure is very simple, has a small number of parts, and is easy to use.

[0041] See also Figure 2 and Figure 6 In some embodiments of the present invention, the movable part 500 is a swing arm with one end rotatably connected to the gimbal body 100, and the other end of the swing arm abuts against the side of the side protrusion 320 away from the elastic member 400, and the operating component 510 is arranged on the side wall of the middle part of the swing arm to rotate and retract in the through hole 130; when the user applies a small external force to push the operating component 510 into the through hole 130, the swing arm can rotate so that the end of the swing arm drives the locking block 300 to rotate around the rotating shaft 310. Of course, in other embodiments, the movable part 500 can also be replaced by a slider that translates relative to the gimbal body 100.

[0042] Specifically, see Figure 2 and Figure 5, in this embodiment, the pan-tilt main body 100 includes a bottom case and a face case fixed to the bottom case by screws. A cavity for accommodating the swing arm, the elastic member 400, the rotating shaft 310, and the locking block 300 is formed between the bottom case and the face case. The through-hole portion 130 is located on the side walls of the bottom case and the face case and communicates with the cavity. This design facilitates production and assembly and also reduces the manufacturing difficulty of the components.

[0043] See Figure 6 , in some embodiments of the present utility model, in order to enable the unlocking mechanism to drive the locking block 300 to rotate a certain angle and then be stable, the surface of the side convex portion 320 facing away from the elastic member 400 is a first plane 321. One end of the swing arm that abuts against the side convex portion 320 is provided with a mating inclined surface 520. When the locking block 300 rotates to retract from the through-hole 120 below the bottom surface of the installation groove 110, a surface-to-surface contact is formed between the first plane 321 and the mating inclined surface 520.

[0044] See Figure 6 , in some embodiments of the present utility model, in order to further improve the stability of the locking block 300 after rotating a certain angle, the upper surface of the locking block 300 facing the swing arm is provided with a second plane 350. The rotating shaft 310 has a default portion where the second plane 350 intersects the first plane 321. When the first plane 321 abuts against the mating inclined surface 520, the second plane 350 abuts against the upper surface of the swing arm. In addition, the setting of the default portion also helps to enhance the structural compactness.

[0045] The present utility model also discloses a photographic equipment, including the pan-tilt device described in any of the above technical solutions. Since the movement stroke of the locking block 300 rotating around the rotating shaft 310 to extend out of the through-hole 120 and retract into the through-hole 120 is short, the thickness dimension of the pan-tilt device of this photographic equipment is small, and it is not easy for the quick-release plate 200 to fall off the pan-tilt main body 100 when the external device is impacted, which is beneficial to the stability of photographic work.

[0046] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0047] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
