Description

Technical Field

[0001] The present invention relates to the technical field of photography auxiliary equipment, and in particular to a quick-locking pan / tilt head. Background Art

[0002] When a camera is mounted on a tripod, it is usually necessary to use a gimbal to fix the camera. Among them, the inverted gimbal is a popular choice for photography enthusiasts because of its small size and convenient adjustment. Most inverted gimbals in the prior art use a buckle-type universal sphere for fixing, but the buckle-type fixation is difficult to control the locking force, that is, it is difficult to control the damping of the universal sphere; secondly, since the buckle locking operation range is large (usually 180 degrees), the finger pull distance is far, and the operating experience is not perfect. Summary of the invention

[0003] In view of this, the purpose of the present invention is to provide a quick-lock gimbal that is easy to control the locking force of the universal ball and has a more convenient locking operation. The operating angle of the plate buckle locking gimbal is less than 60 degrees, and the locking experience is faster and more convenient, solving the technical problems described in the background technology.

[0004] The present invention is achieved through the following technical solutions:

[0005] A quick-lock pan / tilt head, comprising a pan / tilt head seat and a ball sleeve installed in the pan / tilt head seat, wherein a universal ball is rotatably installed in the ball sleeve, and a locking assembly is installed above or below the universal ball;

[0006] The locking assembly includes two locking members arranged vertically in the pan-tilt seat, namely, a locking member A and a locking member B. The locking member A is close to the universal sphere. The locking member A and the locking member B only perform up-down and horizontal rotation movements respectively under the limit of the pan-tilt seat.

[0007] The opposite surfaces of the two locking members protrude to form convex blocks with inclined surfaces. When the locking member B rotates so that the highest points of the upper and lower convex blocks are close to each other, the distance between the two locking members increases accordingly. Under the action of the locking member B, the locking member A moves to abut against the universal ball and lock it.

[0008] Furthermore, a cover plate is fixedly connected to one side of the pan / tilt seat close to the locking member B, and the cover plate protrudes outward toward one side of the locking member B to form a stop plate;

[0009] A stopping groove is formed on the inner wall of the stopping plate, and the locking member A has a stopping portion, which extends into the stopping groove to limit the locking member A from rotating horizontally.

[0010] Furthermore, a strip hole communicating with the inside and outside is formed through the side of the gimbal seat, and a lever is fixedly connected to the locking member B, and an operating end of the lever extends outward through the strip hole.

[0011] Furthermore, a slide groove is provided in the pan-tilt seat, an identification plate is slidably installed in the slide groove, and the identification plate is exposed in the strip-shaped hole;

[0012] The identification plate is provided with a card slot, and the card slot is engaged with the lever. When the lever moves under the action of an external force, the lever drives the identification plate to move, and different identification information is revealed in the bar-shaped hole.

[0013] Furthermore, a groove is formed on one side of the locking member A facing the universal sphere, and a groove wall of the groove fits with the spherical surface of the universal sphere.

[0014] Furthermore, the center of the cover plate protrudes outward toward one side of the locking member B to form a pillar, and a through hole is opened in the center of the locking member B from top to bottom. The pillar extends into the through hole, and a spring is installed between the pillar and the bottom wall of the through hole. The deformation of the spring applies pressure to the universal ball through the locking member, thereby providing basic damping force.

[0015] Furthermore, a bearing is installed between the cover plate and the locking member B, and the bearing is sleeved outside the support column.

[0016] Furthermore, a gasket is installed between the bearing and the cover plate, and a threaded hole is opened on the cover plate. An adjusting screw is threadedly connected in the threaded hole. The height of the gasket can be adjusted by pushing the adjusting screw, thereby adjusting the initial position of the bearing and the locking assembly.

[0017] The beneficial effects of the present invention are:

[0018] 1. When the locking member B rotates clockwise so that the highest points of the upper and lower protrusions are close to each other, the distance between the two locking members increases accordingly, and the locking member A moves under the push of the locking member B, and generates a force on the vertical plane to abut against the universal sphere to lock the universal sphere, thereby locking the shooting angle (of the camera);

[0019] Compared with the existing buckle-type locking method, the present invention can control the locking force of the universal ball by turning the horizontal rotation angle of the locking member B, thereby controlling the damping force of the ball;

[0020] Secondly, the locking member B of the invention can be locked by turning horizontally within a small range (less than sixty degrees), which makes the operation more convenient.

[0021] 2. The height of the gasket can be adjusted by pushing the adjusting screw, thereby adjusting the initial position of the bearing and the locking assembly, and then fine-tuning the locking accuracy of the locking assembly on the universal ball. A spring is installed between the pillar and the bottom wall of the through hole. The spring deformation acts on the locking member B and applies pressure to the universal ball through the locking member A, thereby providing a basic constant damping force for the gimbal, solving the problem of the universal ball being too loose and shaking when the gimbal is unlocked.

DETAILED DESCRIPTION

[0032] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0033] In the description of the present application, the terms "upper", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0034] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 The present invention provides a technical solution: a quick-lock pan / tilt, comprising a pan / tilt seat 1 and a ball sleeve 2 clamped in the pan / tilt seat 1, a universal ball 3 rotatably mounted in the ball sleeve 2, and a locking assembly 4 mounted above or below the universal ball 3;

[0035] When the locking assembly 4 is arranged above the universal sphere 3 , it is an inverted gimbal, and when the locking assembly 4 is arranged below the universal sphere 3 , it is a planar thrust gimbal. The locking assembly 4 is used to abut against the universal sphere 3 to lock the universal sphere 3 .

[0036] See also Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The locking assembly 4 includes two locking members vertically arranged in the pan-tilt seat 1, namely a locking member A41 and a locking member B42. The locking member A41 is close to the universal sphere 3. The two locking members are disc-shaped structures. A groove 14 is provided on the side of the locking member A41 facing the universal sphere 3. The groove wall of the groove 14 fits with the spherical surface of the universal sphere 3, thereby adapting to the shape of the universal sphere 3 to reduce the friction between the universal sphere 3 and the locking member A41 when the universal sphere 3 rotates. Secondly, the contact area with the universal sphere 3 can be increased when locking the universal sphere 3, thereby achieving a better locking effect.

[0037] See also Figure 3 and Figure 5The side of the pan-tilt seat 1 close to the locking member B42 is fixedly connected with a cover plate 6, and the cover plate 6 is fixedly connected to the top opening of the pan-tilt seat 1 by bolts. The cover plate 6 protrudes outward toward the side of the locking member B42 to form a semi-enclosed stop plate 61. A stop groove 62 is provided on the inner wall of the stop plate 61 along the height direction of the stop plate 61, and the locking member A41 has a stop portion 8, and the stop portion 8 extends into the stop groove 62 to limit the horizontal rotation of the locking member A41, and the locking member A41 can move up and down along the stop groove 62.

[0038] See also Figure 1 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 The center of the cover plate 6 protrudes outward toward one side of the locking member B42 to form a pillar 15, and screw holes are provided in the center of the pillar 15 from top to bottom. The clamping seat 22 for mounting photographic equipment can be mounted on the top of the cover plate 6 by bolts and screw holes;

[0039] The locking member B42 is movably mounted outside the pillar 15 and is located on the inner side of the stop plate 61, so that the locking member B42 can make a circular motion around the pillar 15. A strip hole 9 is provided on the side of the pan / tilt seat 1, which is connected to the inside and outside. A lever 10 is fixedly connected to the locking member B42. The operating end of the lever 10 extends outward through the strip hole 9. The locking member B42 can be rotated and made a horizontal circular motion by the lever 10.

[0040] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 A slide groove 11 is provided in the pan-tilt seat 1, and an identification plate 12 is slidably installed in the slide groove 11. The identification plate 12 is exposed in the strip hole 9, and the identification plate 12 is marked with the locking and unlocking direction of the universal ball 3, so that when the locking piece B42 is rotated according to the marked direction, the locking assembly 4 can lock or unlock the universal ball 3.

[0041] See also Figure 5 The identification plate 12 is provided with a card slot 13, and the card slot 13 is engaged with the lever 10. When the lever 10 moves under the action of an external force, the lever 10 drives the identification plate 12 to move and reveals different identification information in the bar-shaped hole 9.

[0042] See also Figure 6 and Figure 8The opposite surfaces of the two locking members protrude to form a convex block 5 with an inclined surface, and the inclined surface slope of the convex block 5 is between 2 and 5 degrees. When the locking member B42 rotates clockwise so that the highest point and the lowest point of the upper and lower convex blocks 5 are close to each other, the distance between the two locking members becomes larger, and the locking member B42 pushes the locking member A41 to move and abut against the universal ball 3 for locking. Since the inclined surface slope of the convex block 5 is almost equal to the plane, when the locking member B42 rotates horizontally between 50 and 60 degrees The locking member A41 has a vertical movement range of about 0.5 to 1.2 mm. It adopts the working principle of inclined plane self-locking, that is, when the component of the object's gravity along the inclined plane is less than or equal to the maximum static friction force, the friction force and the gravity component are balanced to ensure that the object remains stationary under certain conditions and will not slide. Therefore, after manually rotating the locking member B42 to push the locking member A41 to move and lock the universal ball 3, the locking member B42 will not be affected by the reaction force, resulting in locking failure;

[0043] When the locking member B42 rotates counterclockwise to cause the upper and lower protrusions 5 to move along the downward slope direction of the other side's inclined surface, the distance between the two locking members gradually decreases, and the force of the locking member B42 on the locking member A41 decreases. At this time, the universal ball 3 can rotate relative to the ball sleeve 2 to adjust the angle of the clamp seat 22, and then adjust the shooting angle of the photographic equipment.

[0044] See also Figure 7 and Figure 8 A through hole 16 is provided in the center of the locking piece B42 from top to bottom, and the bottom cross-section of the through hole 16 is stepped. The pillar 15 extends into the through hole 16, and a spring 17 is installed between the pillar 15 and the bottom wall of the through hole 16. The spring 17 deforms and acts on the locking piece B42, and applies pressure to the universal ball 3 through the locking piece A41, thereby providing a basic constant damping force for the gimbal, solving the problem of the universal ball 3 being too loose and shaking when the gimbal is unlocked.

[0045] See also Figure 2 , Figure 6 , Figure 7 and Figure 8 A bearing 18 is installed between the cover plate 6 and the locking piece B42. The bearing 18 is sleeved outside the pillar 15. The bearing 18 adopts a planar thrust bearing in the prior art, which is used to provide sliding support for the rotation of the locking piece B42 and reduce friction, thereby improving the hand feel comfort during the operation and rotation process.

[0046] See also Figure 2 , Figure 6 , Figure 7 and Figure 8A gasket 19 is installed between the bearing 18 and the cover plate 6. A threaded hole 20 is opened on the cover plate 6. An adjusting screw 21 is threadedly connected in the threaded hole 20. The height of the gasket 19 can be adjusted by pushing the adjusting screw 21, thereby adjusting the initial position of the bearing 18 and the locking assembly 4, and further fine-tuning the locking accuracy of the locking assembly 4 on the universal ball 3.

[0047] The use process of the present invention: the initial state of the locking assembly 4 is as follows Figure 6 As shown in the figure (the universal sphere 3 is not locked, and the clamp seat 22 can be freely moved for angle adjustment), at this time, the distance between the locking member A41 and the locking member B42 is the minimum, and the lever 10 is moved along the locking direction of the lock mark on the identification plate 12, and the lever 10 drives the locking member B42 to rotate. The rotation of the locking member B42 causes the two protrusions 5 between the locking member A41 to move along the slope direction on the inclined surface, and the distance between the two locking members increases accordingly. The locking member A41 moves under the push of the locking member B42, and generates a force on the vertical plane to abut against the universal sphere 3, thereby locking the universal sphere 3, and then fixing the angle of the clamp seat 22; when it is necessary to unlock the universal sphere 3 and adjust the angle of the clamp seat 22, it is only necessary to move the lever 10 in the opposite direction.

[0048] Finally, it should be noted that the above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention are within the scope of protection required by the present invention.
