As shown in fig. 1-5, a camera stand according to an embodiment of the present invention includes: the ball head adjusting mechanism comprises a main body 2, a ball head 3, an adjusting screw 4, a first sliding block 5, a wedge-shaped block 6 and a second sliding block 7. The base 1 and the flange 8 may also be provided as required.

In the axial direction (or the longitudinal direction) of the main body 2, the ball head 3, the first slide block 5, the wedge block 6 and the second slide block 7 are sequentially arranged in the main body 2. Referring to fig. 2, the wedge block 6 is provided at both ends with a first wedge slope 61 and a second wedge slope 62, respectively, wherein the first wedge slope 61 and the second wedge slope 62 have opposite inclination directions. The first slider 5 has a first inclined surface 51 cooperating with the first wedge inclined surface 61; the second slider 7 has a second inclined surface 72 that cooperates with the second wedge inclined surface 62. A screw through hole 21 is formed in the side wall of the main body 2, and the adjusting screw 4 passes through the screw through hole 21 to be engaged with the wedge block 6, so as to adjust the relative position of the wedge block 6 and the screw through hole 21, and lock the position of the ball head 3 relative to the main body 2, or release the locking.

Moreover, since the first slider 5 and the second slider 7, which are capable of sliding in the axial direction of the body 2, are respectively provided at both ends of the wedge block 6, the height position of the wedge block 6 is not changed or is substantially maintained when the locking movement (specifically, the radial movement) is performed. This also contributes to keeping the direction of extension of the adjusting screw constant or substantially constant.

The adjusting screw 4 can be passed through the screw through hole 21 in a suitable manner and engaged with the wedge block 6 in a suitable manner.

In one embodiment, the screw through hole 21 is a threaded hole, the wedge block 6 is also threaded, and the adjusting screw 4 is not threaded adjacent to the head. Thus, the threaded section of the front end (the end far from the head) of the adjusting screw 4 is screwed through the threaded through hole and then screwed into the threaded hole of the wedge block 6. At this point, the set screw 4 engages the threaded bore adjacent the non-threaded shank of the head. By rotating the adjusting screw 4, the distance between the wedge-shaped block 6 and the adjusting screw 4 can be drawn in, so that the first slider 5 moves upwards, or has a tendency to move upwards, thereby locking the ball head 3 relative to the main body 2. The locking can be released by rotating the adjusting screw 4 in the opposite direction.

In another embodiment, the screw through holes 21 are threaded holes and the wedge block 6 has no threaded holes. The thread section of the adjusting screw 4 is in threaded fit in the screw through hole 21, and the front end (the end far away from the head) of the adjusting screw 4 abuts against the wedge block 6. By rotating the adjusting screw 4, the distance between the front end of the adjusting screw 4 and the screw through hole 21 can be increased, so that the first slider 5 moves upward, or has a tendency to move upward, thereby locking the ball head 3 relative to the main body 2. The locking can be released by rotating the adjusting screw 4 in the opposite direction. It will be appreciated that in this embodiment the set position of the adjustment screw 4 is reversed from that of figure 2. I.e. the adjusting screw needs to be arranged in the left position as shown in fig. 2.

In yet another embodiment, the screw through hole 21 is a smooth hole and the wedge block 6 is provided with a threaded hole. The thread section of the adjusting screw 4 is in threaded fit in the thread hole of the wedge block 6. By rotating the adjusting screw 4, the distance between the wedge 6 and the screw hole 21 can be reduced, so that the first slider 5 moves upwards or has a tendency to move upwards, thereby locking the ball head 3 relative to the main body 2. The locking can be released by rotating the adjusting screw 4 in the opposite direction.

The base 1 is used for mounting or fixing to a ceiling, a wall, a pillar, or other fixed object; or the base may be placed directly on the flat bottom surface. For example, the base 1 may be fixed to a horizontal base by screws through three mounting holes 12 on the base 1. The base 1 is provided at the middle with a central through hole 11, and the main body 2 can pass through the central through hole 11. The shape of the base 1 is not limited to the illustrated shape and structure, but may take any suitable shape and structure.

The main body 2 is a hollow structure. One end is connected with the base 1, and the other end is provided with a hemispherical shell matched with the ball head 3. The body 2 can be connected to the base 1 in any suitable manner and is not limited to the illustrated embodiment. The main body 2 can be connected to the base 1 as one body or integrally formed as needed.

In the illustrated embodiment, the body 2 is generally in the shape of a conical cylinder having a small pitch (e.g., less than 10 degrees), or the conical cylinder can be replaced with a cylindrical cylinder. At the large diameter end of the cone there is provided a shaft shoulder 24, the shaft shoulder 24 extending radially outwardly. The outer diameter of the shaft shoulder 24 is larger than the inner diameter of the central through hole 11 of the base 1, and the maximum diameter of the conical cylinder or the diameter of the cylindrical cylinder is smaller than the inner diameter of the central through hole 11. The body 2 can thus pass through the central through hole 11 of said base 1.

A semispherical shell 23 is provided at the small-diameter end (upper end in fig. 2) of the conical cylinder. A swing groove 22 is provided at the hemispherical shell 23 to allow the shaft portion 32 of the ball head 3 to swing within the swing groove 22. Thereby achieving rotational adjustment in one direction.

The hemispherical shell 23 defines a socket adapted to cooperate with the ball head 31 of the ball head 3.

Referring to fig. 3, screw penetration holes 21 are provided on the side wall of the main body 2. In an alternative embodiment, the threaded bore 21 is a smooth bore, without threads. In another alternative embodiment, the threaded bore 21 is a threaded bore, threaded, such that the adjustment screw 4 is a drop-proof screw, as described in detail below. In the illustrated embodiment, the screw penetration hole 21 is a counter bore having a counter land diameter greater than the diameter of the head of the adjustment screw 4. The adjusting screw 4 is threaded through the screw through hole 21 into the threaded hole 65 of the wedge block 6. The radial position of the wedge-shaped block 6, i.e. the left and right position on the drawing of fig. 2, is adjusted by rotating the adjusting screw 4. Therefore, the ball head 3 moves towards the direction of extruding the ball socket to extrude the ball socket or release the extruding state, and further the fixing and the releasing of the position of the ball head 3 are realized. In the fixed state, the ball head 3 cannot rotate; in the released state, the ball head is able to rotate freely, more specifically, in a three-way rotation, including a swing along the swing groove 22, and a rotation in a plane perpendicular to the axis of the main body 2 (or a rotation about the axis of the main body 2).

As shown in fig. 2 and 3, the ball head 3 includes a ball head portion 31 and a shaft portion 32 connected to the ball head portion 31. In the mounted state, the ball head 31 is fitted with the hemispherical shell 23 of the body 2, and the rod 32 protrudes out of the body 2 through the swing groove 22 of the body 2. The camera or the imaging unit of the camera is mounted, for example, on the shaft 32 of the ball head 3.

Be provided with through wires hole 33 on bulb 3, through wires hole 33 can be used for holding the cable and pass to the realization is to camera imaging unit's power supply to and transmission video signal, control signal lamp etc..

The adjusting screw 4 may be any suitable threaded member. Advantageously, the head of the adjusting screw 4 is provided with a special structure, so that only a special tool is used to drive the adjusting screw 4. For example, in an alternative embodiment, the head of the adjusting screw 4 is provided with an internal hexagonal hole and at the centre of said hole a small cylinder is provided which protrudes. Or, in another alternative embodiment, the head of the adjusting screw 4 is provided with an internal triangular hole.

Referring to fig. 2, in an alternative embodiment, set screw 4 includes a head 43, a polished rod segment 41 connected to head 43, and a threaded segment 42 remote from the head. Wherein the polished rod section 41 has a diameter smaller than the threaded section 42. Correspondingly, the screw through hole 21 on the main body 2 is a threaded hole and can be matched with the threaded section 42, and the axial length of the polished rod section 41 is greater than that of the screw through hole 21. This arrangement is advantageous for preventing the drop of the adjusting screw 4, thereby setting the adjusting screw 4 as a drop-proof screw. In other words, the holes in the body 2 are threaded holes, the screws are partially threaded, and the rest are polished rods. Therefore, after the thread of the adjusting screw is screwed into the main body and then comes out, the adjusting screw needs to be aligned with the screw hole in the main body, and the operation is difficult, so that the anti-falling effect is achieved.

Still referring to fig. 2, the first slider 5 is disposed within the main body 2. In the axial direction, the first slide 5 is located between the ball head 31 and the wedge 6.

The first slider 5 is substantially cylindrical. The side of the first slider 5 remote from the ball head (i.e. the lower side in fig. 2) is provided with a lower bevel 51. The lower inclined surface 51 and the wedge-shaped upper inclined surface 61 of the wedge block 6 are matched with each other, and have the same inclination direction and the same inclination angle. In the axial direction, the wedge block 6 is located between the first slider 5 and the second slider 7. When the wedge block 6 moves to a position close to the screw through hole 21 (i.e., moves to the right in fig. 2), the distance between the first slider 5 and the second slider 7 is increased, so that the first slider 5 is driven to move toward the ball pressing head 31 to lock and fix the ball 3. When the wedge block 6 is moved to a position away from the screw penetration hole 21 (i.e., to the left in fig. 2), the locking of the ball 3 is released.

The peripheral wall of the first slider 5 is provided with a number of guide ribs, in particular, in the embodiment shown, said guide ribs comprise a first guide rib 52 (see fig. 4), a second guide rib 53 (see fig. 4) and a third guide rib 54 (see fig. 3). The guide ribs project radially outward and extend axially. The guide ribs are located at different positions in the circumferential direction. The guide ribs 52 cooperate with corresponding vertical grooves (not shown) in the main body 2 to guide the axial sliding of the first slider 5 with respect to the main body 2 and to prevent the first slider 5 from rotating with respect to the main body 2.

In the illustrated embodiment, three guide ribs are provided. The first guide rib 52 and the third guide rib 54 are arranged opposite one another, spaced apart by 180 degrees in the circumferential direction, and the second guide rib 53 is located between the first guide rib 52 and the third guide rib 54 in the circumferential direction. This has a fool-proof effect, avoiding mounting wrong positions in the circumferential direction.

In addition, three guide ribs have different widths, and thickness is uneven, and this also has the foolproof effect, can avoid adorning the wrong position in circumference, avoids adorning the opposite direction. For example, the width of the second guide rib 53 is greater than the width of the first guide rib 52 and the third guide rib 54. This can prevent the position from being misplaced in the circumferential direction. The first guide rib 52 and the third guide rib 54 may also be further provided with different widths. This can further prevent misorientation in the axial direction.

Referring to fig. 2, the first slider 5 is provided with a rounded arc groove on the upper circumference thereof so as to be engaged with the lower portion of the ball head portion 31 of the ball head 3. More specifically, the lower portion of the ball portion 31 is facilitated to be accommodated. The rounded arc groove can be a part of a spherical surface or a conical surface. The upper end of the first slider 5 is the end adjacent to the ball head 3.

Referring to fig. 3 and 4, an escape notch 55 is further provided at an upper portion of the first slider 5. The escape notch 55 is arranged on the side remote from the adjusting screw 4, so that the ball head 31 can be escaped when the first slide 5 is driven by the wedge 6 to move in the direction of clamping the ball head with a slight radial movement (movement to the right in fig. 2). Thus, the urging force on the ball head portion 31 when the ball head portion is pressed is ensured to be an upward force.

Two first guide planes 56 are arranged on two sides of the inclined surface of the first sliding block 5 and play a role in limiting the movement direction of the wedge-shaped block 6. In particular, the two guide planes 56 serve to prevent the wedge-shaped blocks 6 from rotating. The two first guide planes 56 are disposed facing each other and are disposed parallel to the axis of the main body 2. Correspondingly, two second guide planes 63 are provided on both sides of the wedge-shaped block 6. The two second guide planes 63 of the wedge-shaped block 6 are located between the two first guide planes 56 of the first slider 5.

That is, the first slider 5 is provided with a pair of first guide planes 56 at an end toward the wedge block 6, and the wedge block 6 is provided with a pair of second guide planes 63 thereon, and the pair of first guide planes 56 sandwich the pair of second guide planes 63 to guide the movement of the wedge block 6 in a radial direction toward the screw penetration hole 21 or prevent the wedge block 6 from rotating.

The first guide plane 56 may be provided to extend vertically or may be provided with draft. Similarly, the second guide plane 63 may be provided to extend vertically, or may be provided with draft. In one embodiment, the first guide plane 56 is provided to extend vertically, or substantially vertically; the second guide plane 63 is provided with a draft, or a set draft. For example, the distance between the pair of second guide planes 63 is small in the upper and lower parts, the upper part of the pair of second guide planes 63 can be inserted between the pair of first guide planes 56, and the lower part of the pair of second guide planes 63 is large in the size and cannot be inserted between the pair of first guide planes 56, thereby implementing a fool-proof function and preventing a mistake.

The other end face of the first sliding block 5 is an inclined plane with an angle of 20 degrees, and the friction resistance is reduced by integral polishing.

Still referring to fig. 3, a wedge block 6 is disposed within the body 2. As previously mentioned, the wedge block 6 is located between the first slider 5 and the second slider 7 in the axial direction. The wedge block 6 is of generally cylindrical configuration.

A wedge upper ramp 61 is provided on the side of the wedge block 6 facing the first slide 5. The wedge upper inclined surface 61 cooperates with the lower inclined surface 51 of the first slider 5, and both have the same inclination direction, and further, both have the same inclination angle.

A wedge lower ramp 62 is provided on the side of the wedge block 6 facing the second slide 7. The wedge lower inclined surface 62 cooperates with the upper inclined surface 72 of the second slider 7, both having the same inclination direction, and further both having the same inclination angle.

As shown, the wedge upper inclined surface 61 and the wedge lower inclined surface 62 have opposite inclination directions. Thus, when the wedge block 6 is moved in a direction approaching the screw penetration hole 21 by the tensile force of the adjustment screw 4, the first slider 5 and the second slider 7 are moved in the opposite directions in the axial direction, or the first slider 5 and the second slider 7 have a tendency to move in the opposite directions in the axial direction. Specifically, referring to fig. 2, when the wedge block 6 moves to a position close to the screw penetration hole 21, the first slider 5 is driven to move upward, or an upward force is applied to the first slider 5; at the same time, the second slider 7 is driven to move downward, or a downward force is applied to the second slider 7.

In one example, the wedge upper ramp 61 and wedge lower ramp 62 are each at 20 °. However, in the present invention, the angles of the wedge upper inclined surface 61 and the wedge lower inclined surface 62 are not limited to the above-described angles, and may be selected within a suitable range. For example, the angles of the wedge upper inclined surface 61 and the wedge lower inclined surface 62 can be selected within a range of 10 degrees to 30 degrees.

The wedge block 6 has a pair of (two) second guiding planes 63 on the side, and the two second guiding planes 63 cooperate with the two first guiding planes 56 at the bottom of the first slider 5 to play a guiding role.

In one embodiment, the two second guide planes 63 of the wedge-shaped block have a slope. For example, the draft is small, and is a draft. The distance at the upper ends of the two second guide planes 63 is small and the distance at the lower ends is large. Can cooperate with the vertical plane of first slider and second slider and play spacing foolproof effect, avoid wedge 6 from turning over the dress from top to bottom.

The wedge-shaped block 6 is, for example, a metal piece, the surface of which is polished to help reduce friction and avoid seizure.

The side of the wedge block 6 facing the ball head 3 is provided with a mark with an UP character, so that when the wedge block 6 is installed in the main body 2, the side with the UP character faces upwards or faces the ball head 4, and reverse installation is avoided.

As shown in fig. 3, the second slider 7 is disposed inside the main pattern 2 and on the lower side of the wedge block 6. The second slider 7 is of a substantially cylindrical configuration. The upper end surface of the second slider 7 is an upper inclined surface 72. The upper inclined surface 72 cooperates with the wedge lower inclined surface 62, both having the same inclination direction, further both having the same inclination angle, for example, both being an angle between 15 degrees and 25 degrees, for example, 20 degrees.

The second slider 7 also has a pair (two) of third guide planes 71. The third guide plane 71 of the second slider 7 is in the same position in the circumferential direction as the first guide plane 56 on the first slider 5. A pair (two) of the third guide planes 71 extend vertically and face each other. The third guide plane 71 acts to limit the normal movement of the side plane of the wedge-shaped block 6. As described above, the distance between the two third guide planes 71 is greater than the distance between the two first guide planes 56.

That is, the second slider 7 is provided with a pair of third guide planes 71 at an end toward the wedge block 6, and the pair of third guide planes 71 sandwich the pair of second guide planes (63) to guide the movement of the wedge block 6 in the radial direction toward the screw penetration hole 21. It is to be understood that "clamping" of the present invention refers to positional relationships and does not mean that a force acts on the object being clamped. At its lower end there are two ear-like structures (radially expanded portions 74). The lower surface of the radially expanded portion 74 is provided with first teeth 75. The first tooth 75 is disposed downward. When the second sliding block 7 is pressed downwards, the first teeth 75 are matched with the second teeth 81 on the flange 8, so that the support P is limited to rotate. In the illustrated embodiment, the second teeth 81 are circumferentially spaced, and the first teeth 75 are symmetrically spaced apart from each other over the entire circumference. Thus, the volume of the second slider 7 can be advantageously reduced.

At the same time, the second slider 7 has two second ribs 76 on its side surface, which serve to reinforce the third guide plane 71 and the radially expanded portion 74. In addition, the second ribs 76 can also be arranged to act as axial stops.

Referring to fig. 2 and 3, the flange 8 is mounted to the base 1 by fastening screws 9. The flange 8 substantially fixes the body 2 relative to the base 1. And provides support and axial restraint for the second slider 7.

A ring of second teeth 81 arranged in a ring shape is provided on the upper side of the flange 8. The second teeth 81 are adapted to cooperate with the first teeth 75 to prevent the second slider 7 from rotating relative to the flange 8 and thus the second slider 7 from rotating relative to the base 1.

The wedge block 6 is installed in the main body 2, and the direction with the UP character (orientation mark) faces the ball head 3, so that the reverse installation is avoided. The second slider 7 is then mounted into the body 2. Then, the base 1 is penetrated to the bottom of the main body 2 from top to bottom, the flange 8 is installed on the base 1 through the fastening screw 9, and finally the adjusting screw 4 is screwed. And then the tightness of the ball head 3 is adjusted through an adjusting screw 4, so that the P/T/R three-way rotation of the bracket is adjusted. Any other suitable indicia may be used for the UP font orientation indicia. That is, the installation process of the single-screw three-way locking structure bracket according to an embodiment of the present invention is as follows. The ball head 3 is installed in the main body 2, the first sliding block 5, the wedge block 6 and the second sliding block 7 are sequentially installed in the main body 2, and then the adjusting screw 4 is screwed into the main body 2. Finally, the flange 8 is fastened to the base 1 again by means of fastening screws 9. The step of screwing the adjusting screw 4 into the body 2 can also be carried out at the end.

The utility model discloses a camera mount's theory of operation as follows:

the horizontal movement of the wedge-shaped block 6 is controlled through the tightness of the adjusting screw 4, the wedge-shaped block 6 moves towards the right side of the figure 2 when the adjusting screw 4 is tightened, the first sliding block 5 is limited in the radial direction (for example, the left direction and the right direction in the figure 2) and cannot move, the first sliding block can only move upwards along the plane with the inclination of the wedge-shaped block 6, and the ball head is pressed when the first sliding block moves to a certain distance. At the same time, the wedge block 6 presses the second slide block 7 downwards, and the first teeth 75 of the second slide block 7 press the second teeth of the flange 8, thereby fixing the T/R direction rotation of the ball head and the P direction rotation of the main body.

When the adjusting screw 4 is unscrewed, the wedge block moves towards the left side of the drawing 2, the ball head falls down when the wedge block moves to a certain distance, the wedge block is in a free state, and the support can rotate freely in 3 directions, so that corresponding adjustment can be performed.

The utility model discloses a structure only has 1 screw to expose, moreover, the utility model discloses a simple structure installation, manufacturing cost is lower, in proper order with each component install to the main part inside can.
