Technical Field
[0001] The utility model relates to the technical field of photographic equipment, in particular to a spherical cloud platform with a stable locking structure. Background Art
[0002] A cloud platform is a device for placing (fixing) a shooting device, which is widely used and has various types. The existing cloud platform includes a base and a ball seat. The base has an assembly cavity, and the ball seat is rotatably connected to the base in the assembly cavity. The photographic equipment is connected to the ball seat and the shooting angle of the photographic equipment is adjusted by rotating the ball seat. In order to fix the photographic equipment at a certain shooting angle, a screwing rod is provided on the base, which can rotate relative to the base and abut against the ball seat to lock the ball seat on the base. Since the screwing rod abuts against the ball seat at a point contact, the contact area is small and the locking force is small, so it is easy to slip off and fail, and the locking effect is poor. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a spherical cloud platform with a stable locking structure, so as to solve the problem that in the existing cloud platform, the ball seat is locked on the base by a screwing rod, and the contact area between the screwing rod and the ball seat is small, resulting in a small locking force, easy to slip off and fail, and poor locking effect.
[0004] The utility model is realized by the following technical solutions:
[0005] A spherical cloud platform with a stable locking structure includes a base and a ball seat. The base has an assembly cavity, and the ball seat is rotatably connected to the base in the assembly cavity. A locking space is formed by a gap between the ball seat and the cavity wall of the assembly cavity. A static locking member and a dynamic locking member are arranged in the locking space. The dynamic locking member can move radially in the ball seat to approach the static locking member to lock the ball seat on the base, or move away from the static locking member to release the ball seat. When the dynamic locking member moves close to the static locking member, it cooperates with the static locking member to wrap the ball seat. A driving assembly is arranged on one side of the base where the dynamic locking member is located, and the dynamic locking member is driven by the driving assembly.
[0006] Further, the driving assembly includes a connecting member, an elastic member, a pushing member, a plurality of pushing pins and an external driving rod. The connecting member is connected to the base and has a pushing channel communicated with the locking space. The elastic member, the pushing member, the plurality of pushing pins and the external driving rod are accommodated in the pushing channel and are arranged in sequence from the inside to the outside. The external driving rod can move along the pushing channel to push or release the plurality of pushing pins. When the external driving rod pushes the plurality of pushing pins inward, it drives the pushing member to push the dynamic locking member inward, so that the dynamic locking member moves close to the static locking member to lock the ball seat on the base. When the external driving rod moves outward to release the plurality of pushing pins, the elastic member drives the pushing member to move outward to release the dynamic locking member.
[0007] Further, an arc-shaped notch is formed on one side of the pushing member opposite to the moving locking member, and the arc-shaped notch is for the moving locking member to be inserted and is shaped to fit the outer surface of the moving locking member.
[0008] Further, a positioning hole for one end of the elastic member to be inserted is provided on one side of the pushing member opposite to the moving locking member.
[0009] Further, the pushing channel has an inner pushing channel and an outer pushing channel. The outer pushing channel is communicated with the inner pushing channel through a communication port and is arranged at an angle with the inner pushing channel. The pushing member and several of the pushing pins are accommodated in the inner pushing channel, and the outer driving rod can extend into the inner pushing channel along the outer pushing channel through the communication port to push several of the pushing pins.
[0010] Further, there are 3 pushing pins. Among the three pushing pins, the pushing pin opposite to the pushing member is defined as the main pushing pin, and the other two pushing pins arranged side by side in the radial direction of the inner pushing channel are defined as secondary pushing pins. The two secondary pushing pins can relatively approach or move away from each other in the radial direction of the inner pushing channel to enable the main pushing pin to push or release the pushing member; when the outer driving rod extends into the inner pushing channel to push the secondary pushing pins, the two secondary pushing pins relatively approach to push the main pushing pin to move inwards to push the pushing member, and when the outer driving rod withdraws from the inner pushing channel, the elastic member drives the pushing member to move outwards to make the two secondary pushing pins move away from each other.
[0011] Further, the radius of the main pushing pin is greater than the radius of the secondary pushing pin, and the radius of the secondary pushing pin is greater than the radius of the communication port.
[0012] Further, the shape of one side of the moving locking member opposite to the ball seat fits the outer surface of the ball seat, and the shape of one side of the static locking member opposite to the ball seat fits the outer surface of the ball seat.
[0013] Further, the assembly cavity has an exposed opening for the ball seat to extend out of the base, and the base is provided with a moving limit hole and a static limit hole at the exposed opening; a moving stop strip that is snap-fitted with the moving limit hole to limit the rotation of the moving locking member relative to the base is formed on the moving locking member, and a static stop strip that is snap-fitted with the static limit hole to limit the rotation of the static locking member relative to the base is formed on the static locking member.
[0014] The advantages of this technical solution are that by arranging a static locking member and a moving locking member in the locking space, when the moving locking member moves radially towards the static locking member and approaches it, the ball seat is locked on the base and cooperates with the static locking member to wrap the ball seat. Therefore, when the moving locking member moves closer to the static locking member to lock the ball seat, the ball seat is in surface contact with the moving locking member and the static locking member respectively. The contact surface is wide, the locking force is large (the static friction force is large), it is not easy to loosen, and the locking effect is good. Description of the Drawings

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0025] Embodiment: As Figures 1-7As shown in the figure, a spherical pan-tilt with a stable locking structure includes a base 1 and a ball seat 2. The base 1 has an assembly cavity 101. The ball seat 2 is rotatably connected to the base 1 in the assembly cavity 101. The ball seat 2 is spaced from the cavity wall of the assembly cavity 101 to form a locking space 102. A static locking member 3 and a dynamic locking member 4 are arranged in the locking space 102. The dynamic locking member 4 can move radially in the ball seat 2 to approach the static locking member 3 to lock the ball seat 2 on the base 1, or move away from the static locking member 3 to release the ball seat 2. When the dynamic locking member 4 moves close to the static locking member 3, it cooperates with the static locking member 3 to wrap the ball seat 2. On one side of the dynamic locking member 4 of the base 1, there is a driving assembly 5, and the dynamic locking member 4 is driven by the driving assembly 5. This embodiment provides a spherical pan-tilt with a stable locking structure to solve the problem that in the existing pan-tilt, the ball seat is locked on the base by a screwing rod, and the contact area between the screwing rod and the ball seat is small, resulting in a small locking force, easy slippage and failure, and poor locking effect. The main solution is to configure a static locking member 3 and a dynamic locking member 4 in the locking space 102. When the dynamic locking member 4 moves radially in the ball seat 2 to approach the static locking member 3, the ball seat 2 is locked on the base 1 and cooperates with the static locking member 3 to wrap the ball seat 2. Therefore, when the dynamic locking member 4 moves close to the static locking member 3 to lock the ball seat 2, the ball seat 2 is in surface contact with the dynamic locking member 4 and the static locking member 3 respectively, with a wide contact surface and a large locking force (large static friction force), not easy to loosen, and good locking effect.
[0026] In the embodiment of the present invention, the driving assembly 5 includes a connecting member 501, an elastic member 502, a pushing member 503, a plurality of push pins 504 and an outer driving rod 505. The connecting member 501 is connected to the base 1 and has a pushing channel 506 communicating with the locking space 102. The elastic member 502, the pushing member 503, a plurality of push pins 504 and the outer driving rod 505 are accommodated in the pushing channel 506 and are arranged in sequence from the inside to the outside. The outer driving rod 505 can move along the pushing channel 506 to push or release a plurality of push pins 504. When the outer driving rod 505 pushes a plurality of push pins 504 inward, it drives the pushing member 503 to push the dynamic locking member 4 inward, so that the dynamic locking member 4 moves close to the static locking member 3 to lock the ball seat 2 on the base 1. When the outer driving rod 505 moves outward to release a plurality of push pins 504, the elastic member 502 drives the pushing member 503 to move outward to release the dynamic locking member 4, so that the dynamic locking member 4 releases the static locking member 3. The above setting configures the driving assembly 5 as a connecting member 501, an elastic member 502, a pushing member 503, a plurality of push pins 504 and an outer driving rod 505. When the outer driving rod 505 pushes a plurality of push pins 504 inward, it drives the pushing member 503 to push the dynamic locking member 4 inward, so that the dynamic locking member 4 moves close to the static locking member 3 to lock the ball seat 2 on the base 1. When the outer driving rod 505 moves outward to release a plurality of push pins 504, the elastic member 502 drives the pushing member 503 to move outward to release the dynamic locking member 4. The driving structure is compact and the locking effect is good.
[0027] In an embodiment of the present utility model, an arc-shaped notch 507 is formed on the side of the pushing member 503 opposite to the moving locking member 4. The arc-shaped notch 507 is for the moving locking member 4 to be inserted and is in shape fit with the outer surface of the moving locking member 4. The above arrangement, by configuring the arc-shaped notch 507 on the pushing member 503 for the moving locking member 4 to be inserted and in shape fit with the outer surface of the moving locking member 4, enables the pushing member 503 to have a wide contact surface with the moving locking member 4 when in contact, a large locking force (large static friction force), is not prone to loosening, and has a good locking effect.
[0028] In an embodiment of the present utility model, a positioning hole 508 for one end of the elastic member 502 to be inserted is provided on the side of the pushing member 503 opposite to the moving locking member 4. Preferably, the positioning hole 508 is opened on the arc-shaped notch 507. The above arrangement, by configuring the positioning hole 508 on the arc-shaped notch 507 for one end of the elastic member 502 to be inserted, enables the elastic member 502 to be stably assembled.
[0029] In an embodiment of the present utility model, the pushing channel 506 has an inner pushing channel 509 and an outer pushing channel 510. The outer pushing channel 510 is communicated with the inner pushing channel 509 through a communication port (not marked in the figure) and is arranged at an angle with the inner pushing channel 509. The pushing member 503 and several pushing pins 504 are accommodated in the inner pushing channel 509, and the outer driving rod 505 can extend into the inner pushing channel 509 along the outer pushing channel 510 through the communication port to push the several pushing pins 504. Preferably, the inner pushing channel 509 and the outer pushing channel 510 are perpendicular to each other. The above arrangement, by configuring the pushing channel 506 as the inner pushing channel 509 and the outer pushing channel 510 which are communicated with each other and arranged at an angle, enables the components forming the driving assembly 5 to be assembled compactly and reasonably.
[0030] In an embodiment of the present utility model, there are 3 pushing pins 504. Among the three pushing pins 504, the pushing pin 504 opposite to the pushing member 503 is defined as the main pushing pin 511, and the other two pushing pins 504 arranged side by side in the radial direction of the inner pushing channel 509 are defined as the secondary pushing pins 512. The two secondary pushing pins 512 can relatively approach or move away from each other in the radial direction of the inner pushing channel 509 to make the main pushing pin 511 push or release the pushing member 503. When the outer driving rod 505 extends into the inner pushing channel 509 to push the secondary pushing pins 512, the two secondary pushing pins 512 relatively approach to push the main pushing pin 511 to move inwards to push the pushing member 503. When the outer driving rod 505 withdraws from the inner pushing channel 509, the elastic member 502 drives the pushing member 503 to move outwards to make the two secondary pushing pins 512 move away from each other. The above arrangement, by configuring the several pushing pins 504 as the main pushing pin 511 and the two secondary pushing pins 512, and the secondary pushing pins 512 can relatively approach or move away from each other in the radial direction of the inner pushing channel 509, enables the pushing member 503 to push or release the moving locking member 4 when the outer driving rod 505 extends into or withdraws from the inner pushing channel 509, and the driving structure is simple and compact.
[0031] In the embodiment of the present utility model, the radius of the main abutting pin 511 is greater than that of the secondary abutting pin 512, and the radius of the secondary abutting pin 512 is greater than that of the communication port. The above arrangement makes the movement of the three abutting pins 504 smooth by configuring the radius of the main abutting pin 511 to be greater than that of the secondary abutting pin 512, and avoids the secondary abutting pin 512 from slipping into the outer pushing channel 510 by configuring the radius of the secondary abutting pin 512 to be greater than that of the communication port.
[0032] In the embodiment of the present utility model, the side of the movable locking member 4 opposite to the ball seat 2 is in shape fit with the outer surface of the ball seat 2, and the side of the static locking member 3 opposite to the ball seat 2 is in shape fit with the outer surface of the ball seat 2. The above arrangement maximizes the contact area between the movable locking member 4 and the static locking member 3 and the outer surface of the ball seat 2 in the locked state by configuring the side of the movable locking member 4 opposite to the ball seat 2 to be in shape fit with the outer surface of the ball seat 2 and configuring the shape fit with the outer surface of the ball seat 2 to be in shape fit with the outer surface of the ball seat 2, resulting in a large locking force (large static friction force), not easily loosening, and a good locking effect.
[0033] In the embodiment of the present utility model, the assembly cavity 101 has an exposed port 103 for the ball seat 2 to protrude from the base 1. The base 1 is provided with a moving limit hole 104 and a static limit hole 105 at the exposed port 103. A moving stop strip 402 that is in snap-fit with the moving limit hole 104 to limit the rotation of the movable locking member 4 relative to the base 1 is formed on the movable locking member 4, and a static stop strip 302 that is in snap-fit with the static limit hole 105 to limit the rotation of the static locking member 3 relative to the base 1 is formed on the static locking member 3. The above arrangement limits the rotation of the movable locking member 4 / the static locking member 3 relative to the base 1 by configuring the moving limit hole 104 and the static limit hole 105 at the exposed port 103, configuring the moving stop strip 402 on the movable locking member 4, and configuring the static stop strip 302 on the static locking member 3, so that when the two cooperate to lock the ball seat 2 on the base 1, a good locking effect is achieved.
