Description

Technical Field

[0001] The utility model relates to the technical field of supporting devices for photographic equipment, and particularly relates to a ball head locking mechanism and a tripod. Background Technique

[0002] In the photography industry, a tripod is a very common supporting device for photographic equipment, which has the advantage of being easy to carry. In order to meet the needs of rotating shooting, switching between close-up and long-shot shooting, and dynamic tracking shooting, most tripods on the market have the function of freely swinging in all directions around a support point. However, when shooting still for a long time, the tripod needs to be fixed, so a locking mechanism is required to complete the switching between free swinging and locking.

[0003] Existing tripods mainly achieve rotating shooting through the structure of a ball head and a ball bowl, that is, the ball head rotates in the ball bowl, driving the camera to rotate to any angle for shooting. When shooting still for a long time, a plastic locking mechanism is used to abut against the ball head to lock the ball head for still shooting. This facilitates the frequent switching of the support between the free swinging state and the locking state.

[0004] However, the existing plastic locking mechanism is integrally provided with a push block, so that the plastic locking mechanism can only abut against the ball head tightly at one end, and there is always a gap between the other end and the side wall, unable to achieve tight fitting. Therefore, when the tripod is slightly affected by external force, the ball head is prone to shaking, resulting in the shaking of the shooting picture and affecting the shooting effect. Content of the Utility Model

[0005] The purpose of the utility model is to provide a ball head locking structure and a tripod to solve the problems in the above background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is to provide a ball head locking mechanism, which includes a ball bowl assembly and a locking assembly. The ball bowl assembly includes a fixing cap and a fixing seat. A groove is provided at the top end of the fixing seat, and the ball head is embedded in the groove. The fixing cap covers the ball head and is connected to the top end of the fixing seat, and the fixing cap confines the ball head in the groove. The locking assembly includes a locking head and a pushing block. An activity cavity is provided in the fixing seat, and the activity cavity is communicated with the groove through a through hole provided. The pushing block is arranged in the activity cavity. A connection hole is provided on the ball head. The locking head includes a first locking end and a second locking end. The first locking end passes through the through hole and abuts against the connection hole, and the second locking end is located in the through hole. The pushing block abuts against the second locking end so that the pushing block is clamped in the through hole.

[0007] Furthermore, the connection hole is arranged directly below the ball head. The connection hole is a frustum-shaped hole and the opening at the end is arranged in a gradually expanding structure. The structure of the first locking end is adapted to the connection hole.

[0008] Further, the second locking end is provided with a plugging slot, and an opening slot is provided on the side wall of the second locking end. The pushing block includes an abutting head, and the abutting head is embedded in the plugging slot and the side wall of the second locking end abuts against the through hole.

[0009] Further, the abutting head has a frustum structure, the plugging slot is adapted to the abutting head, and a gap is left between the bottom end of the plugging slot and the abutting head.

[0010] Further, the locking assembly further includes a connecting member. One end of the connecting member is connected to the pushing block, and the other end is connected to the locking head. The connecting member enables the pushing block and the locking head to move relatively.

[0011] Further, one end of the connecting member is fixed on the pushing block, the other end passes through the locking head and is provided with a clamping joint, and a movable margin is left between the clamping joint and the locking head. The clamping joint can abut against the locking head and drive the locking head to move.

[0012] Further, the locking assembly further includes an elastic driving member. The elastic driving member is disposed in the movable cavity, and the elastic driving member pushes the pushing block and further pushes the locking head to be plugged into the connecting hole.

[0013] Further, the ball head locking mechanism further includes an unlocking assembly. A sliding slot is provided on the fixed seat. The unlocking assembly is connected to the pushing block through a connecting screw. The pushing block passes through the sliding slot and slides in the sliding slot.

[0014] Further, the locking head is made of plastic material.

[0015] Further, the present invention also provides a tripod, which adopts the above-mentioned ball head locking mechanism.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. The locking head and the pushing block are separately arranged. After the pushing block moves, it drives the first locking end of the locking head to pass through the through hole and abut against the connecting hole of the ball head to achieve abutment. When the pushing block moves, it can abut against the second locking end of the locking head, so that the second locking end is clamped in the through hole. After the locking head in this application is locked, both ends of the locking head are fixedly clamped and there is no movable gap. At this time, even if the tripod is slightly impacted by an external force, the ball head is not easy to shake, making the shooting picture of the camera more stable.

[0018] 2. The connecting hole is arranged directly below the ball head. The connecting hole is a frustum-shaped hole and the opening at the end is arranged in a gradually expanding structure, which is convenient for the first locking end to be inserted into the connecting hole and abut against the side wall of the connecting hole.

[0019] 3. The second locking end is provided with a plugging slot, and the side wall of the second locking end is provided with an opening slot. By providing the opening slot, the deformation of the second locking end is facilitated. The pushing block includes an abutting head, and the abutting head has a frustum structure. The plugging slot is adapted to the abutting head, and the abutting head is embedded in the plugging slot and the side wall of the second locking end abuts against the through hole after deformation.

[0020] 4. The locking assembly further includes a connecting member. One end of the connecting member is connected to the pushing block, and the other end is connected to the locking head. The connecting member enables the pushing block and the locking head to move relatively. After the pushing block is removed from the plugging slot, through the provided connecting member, the locking head can be driven to be removed from the connecting hole, realizing the unlocking of the ball head.

[0032] Embodiment 1

[0033] Refer to Figures 1 to 4, as a ball head locking mechanism provided by an embodiment of the present utility model, includes a ball bowl assembly 1 and a locking assembly 2. The ball bowl assembly 1 includes a fixing cap 11 and a fixing seat 12. A groove 121 is provided at the top of the fixing seat 12. The ball head 4 is embedded in the groove 121. The fixing cap 11 covers the ball head 4 and is connected to the top of the fixing seat 12. The fixing cap 11 confines the ball head 4 within the groove 121. The locking assembly 2 includes a locking head 21 and a pushing block 22. An activity cavity 122 is provided within the fixing seat 12. The activity cavity 122 communicates with the groove 121 through a through hole 123 provided. The pushing block 22 is disposed within the activity cavity 122. A connection hole 41 is provided on the ball head 4. The locking head 21 includes a first locking end 211 and a second locking end 212. The first locking end 211 passes through the through hole 123 and abuts against the connection hole 41. The second locking end 212 is located within the through hole 123. The pushing block 22 abuts against the second locking end 212 so that the pushing block 22 is clamped within the through hole 123.

[0034] The locking head 21 and the pushing block 22 are separately provided. After the pushing block 22 moves, it drives the first locking end 211 of the locking head 21 to pass through the through hole 123 and abut against the connection hole 41 of the ball head 4 to achieve abutment. While the pushing block 22 moves, it can abut against the second locking end 212 of the locking head 21, so that the second locking end 212 is clamped within the through hole 123. After the locking head 21 in this application is locked, both ends of the locking head 21 are fixedly clamped and there is no play. Even if the tripod is slightly impacted by an external force at this time, the ball head 4 is not easily shaken, making the shooting picture of the camera more stable.

[0035] Specifically, a bushing 125 is provided within the groove 121. The bushing 125 is sleeved on the ball head 4, so that the shape of the ball head 4 is adapted to that of the groove 121, facilitating the smooth rotation of the ball head 4 in any direction within the groove 121. The fixing cap 11 has a sleeve structure. The top connecting rod portion of the ball head 4 passes through the fixing cap 11. The fixing cap 11 can be screwed onto the top of the fixing seat 12 by means of threaded connection, or can be fixed to the top of the fixing seat 12 in the form of snap connection. The fixing cap 11 confines the ball head 4 within the groove 121 to prevent the ball head 4 from coming out. The connection hole 41 is provided directly below the ball head 4. The connection hole 41 is a frustum-shaped hole and the opening at the end is provided with a gradually expanding structure, facilitating the insertion of the first locking end 211 into the connection hole 41 and abutting against the side wall of the connection hole 41. The structure of the first locking end 211 is adapted to the connection hole 41, facilitating the clamping of the first locking end 211. In this embodiment, the locking head 21 is made of plastic material.

[0036] As a variable embodiment, the connecting hole 41 can also be a cylindrical hole structure. At this time, the first locking end 211 is arranged in a frustum shape, and the first locking end 211 can be inserted into the connecting hole 41 and clamped in the connecting hole 41. At this time, the contact surface between the first locking end 211 and the connecting hole 41 is small, and compared with the above clamping method, the connection stability is poor.

[0037] Furthermore, the second locking end 212 is provided with a plugging groove 213, and an opening groove 214 is provided on the side wall of the second locking end 212. The pushing block 22 includes an abutting head 221, and the abutting head 221 is embedded in the plugging groove 213 and makes the side wall of the second locking end 212 abut against the through hole 123.

[0038] Specifically, a plugging groove 213 is provided at the middle position of the second locking end 212, and a plurality of opening grooves 214 are provided on the side wall of the second locking end 212. The plurality of opening grooves 214 uniformly enclose the plugging groove 213 for one week, and the opening grooves 214 communicate with the plugging groove 213. By providing the opening grooves 214, it is convenient for the second locking end 212 to deform. The abutting head 221 has a frustum structure, and the plugging groove 213 is adapted to the abutting head 221 and is also arranged in a frustum shape. After the abutting head 221 is embedded in the plugging groove 213 and the second locking end 212 deforms, the side wall abuts against the through hole 123 and is locked in the through hole 123. A gap is left between the bottom end of the plugging groove 213 and the top end of the abutting head 221 to prevent interference between the two when they abut, so that the side wall of the second locking end 212 cannot abut against the through hole 123.

[0039] As a variable embodiment, the abutting head 221 can also be cylindrical or conical. At this time, the plugging groove 213 can be arranged in a frustum shape or a cylindrical shape, and the abutting head 221 can be inserted into the plugging groove 213 and clamped in the plugging groove 213. At this time, the contact surface between the abutting head 221 and the plugging groove 213 is small, and compared with the above clamping method, the connection stability is poor.

[0040] Furthermore, the locking assembly 2 further includes a connecting member 23. One end of the connecting member 23 is connected to the pushing block 22, and the other end is connected to the locking head 21. The connecting member 23 enables the pushing block 22 and the locking head 21 to move relatively. After the pushing block 22 is removed from the plugging groove 213, through the provided connecting member 23, the locking head 21 can be driven to be removed from the connecting hole 41 to realize the unlocking of the ball head 4.

[0041] Specifically, the ball head locking mechanism further includes an unlocking component 3. The unlocking component 3 includes a connecting screw 31 and an unlocking block 32. A sliding groove 124 is provided on the side wall of the fixed seat 12, and the sliding groove 124 communicates with the moving cavity 122. The unlocking block 32 is fixed to the connecting screw 31. One end of the connecting screw 31 passes through the sliding groove 124 and extends into the moving cavity 122 and is fixedly connected to the pushing block 22. The connecting screw 31 slides in the sliding groove 124. By pushing the unlocking block 32, the connecting screw 31 can be driven to slide in the sliding groove 124, thereby realizing the lifting of the pushing block 22 and realizing the locking and unlocking of the ball head 4. One end of the connecting member 23 is fixed to the pushing block 22, and the other end passes through the locking head 21 and is provided with a clamping joint 231. There is a clearance between the clamping joint 231 and the locking head 21. After the pushing block 22 moves a certain distance, the clamping joint 231 abuts against the locking head 21 and drives the locking head 21 to move. In this embodiment, the connecting member 23 can be a screw. Among them, there is a clearance between the clamping joint 231 and the locking head 21, aiming to ensure that the locking head 21 and the pushing block 22 are arranged in a split structure. Otherwise, it is impossible to fix and clamp both ends of the locking head 21 and there is no clearance.

[0042] As a variable embodiment, one end of the connecting member 23 is fixed to the locking head 21, and the other end passes through the locking head 21 and is connected to the pushing block 22. At this time, a connecting groove can be provided on the abutting head 221. The other end of the connecting member 23 passes through the locking head 21 and is inserted into the connecting groove. A clamping joint 231 is provided at one end of the connecting groove, and there is a clearance between the clamping joint 231 and the connecting groove. At this time, the above functions can also be realized.

[0043] Furthermore, the locking component 2 further includes an elastic driving member 24. The elastic driving member 24 is arranged in the moving cavity 122. The elastic driving member 24 pushes the pushing block 22 and then pushes the locking head 21 to be inserted into the connecting hole 41.

[0044] Specifically, the elastic driving member 24 is a spring. The spring is arranged in the movable cavity 122, with one end abutting against the bottom wall of the movable cavity 122 and the other end abutting against the pushing block 22. In order to make the spring directly face the center of the pushing block 22, limiting grooves are provided at the bottom end of the pushing block 22 and the bottom of the movable cavity 122. The spring is installed between the two limiting grooves and is limited in the limiting grooves at this time, so that it can abut against the center of the pushing block 22. In order to facilitate the quick unlocking of the ball head 4, a plurality of sliding grooves 124 are provided on the side wall of the fixed seat 12. A connecting screw 31 is slidably connected in each sliding groove 124. One end of the connecting screw 31 is connected to the unlocking block 32, and the other end is connected to the pushing block 22. At this time, the unlocking block 32 is arranged in a ring shape and sleeved on the side wall of the fixed seat 12. The whole unlocking block 32 is directly held by hand to move the pushing block 22. By providing a plurality of sliding grooves 124 and a plurality of connecting screws 31, the pushing block 22 can be evenly stressed and quickly moved out, realizing the quick unlocking of the ball head 4.

[0045] As a variable embodiment, in order to make the spring directly face the center of the pushing block 22, limiting protrusions are provided at the bottom end of the pushing block 22 and the bottom of the movable cavity 122. The two ends of the spring are respectively sleeved on the two limiting protrusions. At this time, the spring can also accurately abut against the center position of the pushing block 22. When designing, the displacement distance of the pushing block 22 needs to be considered. At this time, the movable cavity 122 should be set higher to avoid interference caused by the two limiting protrusions abutting against each other, resulting in the inability to unlock the ball head 4.

[0046] The using process of the ball head locking mechanism in this application is as follows:

[0047] When unlocking, press the unlocking block 32. After the unlocking block 32 moves, it drives the pushing block 22 to move through the connecting screw 31. After the pushing block 22 moves, it drives the abutting head 221 to move out of the insertion slot 213. At this time, after the second locking end 212 of the locking head 21 loses the abutting effect of the abutting head 221, the second locking end 212 contracts and loses the abutting effect with the through hole 123. As the pushing block 22 continues to move, the pushing block 22 drives the locking head 21 to move through the connecting member 23. After the locking head 21 moves, the first locking end 211 of the locking head 21 moves out of the connecting hole 41. At this time, after losing the locking effect of the locking head 21, the ball head 4 can be rotated to any position, and the ball head 4 is held by hand to perform a short-term grasping and shooting at any position. At this time, the elastic driving member 24 is compressed by the pushing block 22 and continues to generate elastic force.

[0048] When the ball head 4 needs to be locked for long-time static shooting, the ball head 4 is rotated to the vertical direction so that the connection hole 41 of the ball head 4 faces directly downward. At this time, under the pushing action of the elastic driving member 24, the pushing block 22 moves upward. After the pushing block 22 moves upward, it drives the locking head 21 to move upward through the connecting member 23. The locking head 21 is aligned with the connection hole 41, and the first locking end 211 of the locking head 21 passes through the through hole 123 and abuts against the connection hole 41 of the ball head 4 to achieve abutment. While the pushing block 22 moves, the abutting head 221 on the pushing block 22 abuts against the insertion slot 213, so that the second locking end 212 of the locking head 21 deforms and abuts and is clamped in the through hole 123. After the locking head 21 in this application is locked, both ends of the locking head 21 are fixedly clamped and there is no play. At this time, even if the tripod is slightly impacted by an external force, the ball head 4 is not likely to shake, making the shooting picture of the camera more stable. While the pushing block 22 moves, it drives the unlocking block 32 to reset, facilitating the next unlocking action of the unlocking block 32.

The pushing block 22 abuts against the second locking end 212 to make the pushing block 22 clamped in the through hole 123.

[0052] The locking head 21 and the pushing block 22 are separately arranged. After the pushing block 22 moves, it drives the first locking end 211 of the locking head 21 to pass through the through hole 123 and abut against the connection hole 41 of the ball head 4 to achieve abutment. While the pushing block 22 moves, it can abut against the second locking end 212 of the locking head 21, so that the second locking end 212 is clamped in the through hole 123.
