For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] As shown in the accompanying drawings, the utility model comprises a tripod base 1 and a universal ball bracket 2. The tripod base 1 has three foldable supporting legs 3 in a circular array around it. The universal ball bracket 2 is installed on the top of the tripod base 1 through a quick lock mechanism 4.

[0031] The universal ball bracket 2 includes a universal ball head and a universal ball head hinge support that can be rotated and locked on the universal ball head. The universal ball head hinge support is used to connect the pan head or a telescopic column with a pan head, which can be applied to various shooting requirements. The universal ball bracket 2 is used for shooting at multiple angles. The three foldable support legs 3 of this case are a smaller tripod in the folded state, and can become a larger tripod after unfolding. Whether to unfold can be selected according to the model and size of the shooting equipment, which is more flexible and convenient to use.

[0032] The quick lock mechanism 4 is used to quickly fix the universal ball joint support. When multi-angle shooting is required, the quick lock mechanism 4 is released and the universal ball joint support can be tilted. Conversely, when fixed shooting is required, the quick lock mechanism 4 locks the universal ball joint support.

[0033] The foldable supporting leg 3 includes a first leg 5 and a second leg 6 which are hinged to each other. The first leg 5 is hinged to the tripod base 1 through a pin shaft, and an angle adjustment locking mechanism 7 which cooperates with the tripod base 1 is provided on the first leg 5; the angle adjustment locking mechanism 7 is used to control the tilting angle of the first leg 5, that is, the opening amplitude of the three first legs 5.

[0034] Specifically, the quick lock mechanism 4 includes a guide positioning shaft 20, a telescopic upright sleeve 21 and a rotating positioning sleeve 22. The guide positioning shaft 20 is fixedly connected to the tripod base 1. A core shaft 23 with one end connected to the universal ball bracket 2 is coaxially provided on the guide positioning shaft 20. The rotating positioning sleeve 22 and the telescopic upright sleeve 21 are respectively sleeved on the guide positioning shaft 20 in sequence through the core shaft 23. A tension spring 24 is provided between the rotating positioning sleeve 22 and the guide positioning shaft 20.

[0035] A group of wedge-shaped sliders 25 are provided on the rotating positioning sleeve 22, a group of wedge-shaped positioning blocks 26 cooperating with the wedge-shaped sliders 25 are provided in the guide positioning shaft 20, a circle of corrugated guide grooves 27 cooperating with the wedge-shaped sliders 25 are provided on the telescopic upright sleeve 21, and a pressure handle 28 for controlling the downward pressure of the telescopic upright sleeve 21 is provided on the core shaft 23.

[0036] The guide positioning shaft 20, the telescopic upright sleeve 21 and the rotating positioning sleeve 22 are all cylindrical structures. The guide positioning shaft 20 is a fixed part. The pressing handle 28 is hinged on the core shaft 23 through a pin. The telescopic upright sleeve 21 is provided with a vertical long hole for the pin to avoid. The telescopic upright sleeve 21 and the rotating positioning sleeve 22 are both movable parts. By pressing the pressing handle 28, the telescopic upright sleeve 21 moves downward on the guide positioning shaft 20 with the rotating positioning sleeve 22. At the same time, the rotating positioning sleeve 22 can be rotated through the cooperation of the wedge-shaped slider 25, the wedge-shaped positioning block 26 and the corrugated guide groove 27.

[0037] In specific usage, when the quick lock mechanism 4 is in the locked state, the wedge-shaped slider 25 is located between two adjacent wedge-shaped positioning blocks 26. At this time, the telescopic upright sleeve 21 is in an upwardly lifted state, and one end of its top is connected to the bottom of the ball head seat of the universal ball bracket 2, so that the ball head seat cannot rotate.

[0038] When unlocking, the pressing handle 28 is pressed downward, and the pressing handle 28 controls the telescopic upright sleeve 21 and the rotating positioning sleeve 22 to move downward a certain distance. When the rotating positioning sleeve 22 is pressed downward, the wave crest position of the corrugated guide groove 27 contacts the inclined surface of the wedge slider 25, so that the rotating positioning sleeve 22 has a radial torque until the wedge slider 25 moves to a position lower than the wedge positioning block 26. At this time, the rotating positioning sleeve 22 can be rotated by an angle so that the wedge slider 25 is located below the wedge positioning block 26. The pressing handle 28 is released, and the telescopic upright sleeve 21 and the rotating positioning sleeve 22 are reset under the action of the tensioning spring 24. At this time, the two inclined surfaces of the wedge slider 25 and the wedge positioning block 26 cooperate. The wedge slider 25 is blocked by one side of the wedge positioning block 26 after rotating an angle, that is, the entire rotating positioning sleeve 22 is blocked by the wedge positioning block 26 and fixed in a fixed position in the guide positioning shaft 20. At this time, the telescopic upright sleeve 21 is in a released state, that is, the quick lock mechanism 4 is in an unlocked state, and the universal ball bracket 2 can be adjusted in angle.

[0039] After the wedge-shaped slider 25 and the wedge-shaped positioning block 26 are completely fitted and fixed, the rotation angle of the wedge-shaped slider 25 is just located at the wave crest position of the next corrugated guide groove 27 .

[0040] Therefore, the pressing handle 28 is pressed downward again, the telescopic upright sleeve 21 and the rotating positioning sleeve 22 move downward, and the corrugated guide groove 27 causes the rotating positioning sleeve 22 to have a radial torque again. When the wedge-shaped slider 25 moves downward and disengages from the wedge-shaped positioning block 26, the rotating positioning sleeve 22 rotates an angle again, so that the wedge-shaped slider 25 rotates between two adjacent wedge-shaped positioning blocks 26. After the pressing handle 28 is released, the telescopic upright sleeve 21 and the rotating positioning sleeve 22 are pushed upward by the tensioning spring 24, and the telescopic upright sleeve 21 is in a locked state again.

[0041] Furthermore, a U-shaped groove is provided at the bottom of the first leg 5 and the second leg 6, and the second leg 6 is hinged in the U-shaped groove of the first leg 5 through a pin shaft. A connecting piece 10 is provided in the U-shaped groove at the connecting end of the second leg 6, and one end of the connecting piece 10 is located on the outside of the second leg 6.

[0042] The connecting member 10 is an L-shaped structure, with one end located in the U-shaped groove of the second supporting leg 6 and the other end located outside the second supporting leg 6. When in a folded state, the connecting member 10 located at the outer end is used to act as a supporting pad for the end of the entire supporting leg.

[0043] Preferably, an anti-skid pad 11 is provided on the connecting member 10 located at one end of the outer side of the second supporting leg 6. That is, an anti-skid pad is provided on the supporting pad to play an anti-skid role.

[0044] Furthermore, the middle width of the U-shaped groove of the first leg 5 is smaller than the groove width at both ends, and the width of the second leg 6 at the end opposite to the connecting piece 10 is not less than the middle width of the U-shaped groove of the first leg 5 .

[0045] That is, the two side walls of the U-shaped groove at the end of the second leg 6 are open to both sides.

[0046] When in the folded state, after the second leg 6 is folded into the U-shaped groove of the first leg 5 , the U-shaped groove in the middle of the first leg 5 can clamp the end of the second leg 6 .

[0047] Furthermore, a downwardly recessed access opening 12 is provided in the middle of the U-shaped groove of the first leg 5, so as to facilitate the quick removal of the second leg 6 from the first leg 5.

[0048] Preferably, the angle adjustment locking mechanism 7 includes a fixed sleeve 13, a locking slider 14 and a locking slider driving pressure rod 15. There are three groups of toothed positioning plates 16 corresponding to the first leg 5 in a circular array on the tripod base 1. The locking slider 14 is provided with a locking protrusion 17 that cooperates with the toothed positioning plate 16. The fixed sleeve 13 is fixedly installed in the U-shaped groove of the first leg 5. The locking slider driving pressure rod 15 is installed on the first leg 5 and drives the locking slider 14 to move back and forth in the fixed sleeve 13 to cooperate with the toothed positioning plate 16 to lock or release.

[0049] One end of the fixed sleeve 13 is open, and the locking slider 14 is movably installed in the fixed sleeve 13 through a compression spring. The locking slider 14 is provided with an inclined slot 18, and the locking slider driving pressure rod 15 is provided with a wedge surface 19 that matches the inclined slot 18. The locking slider driving pressure rod 15 is movably installed on the first support leg 5, and drives the locking slider 14 to move through the wedge surface 19 and the inclined slot 18.

[0050] The locking slider driving rod 15 is a movable part, which can move left and right on the fixed sliding sleeve 13, and the locking slider 14 is a movable part, which can move forward and backward on the fixed sliding sleeve 13. The locking slider 14 is provided with a transverse long hole for avoiding the locking slider driving rod 15. By default, the locking slider 14 is braced forward by the compression spring, so that the locking protrusion 17 and the toothed positioning plate 16 are closely matched, and the first leg 5 is in a locked state. When the locking slider driving rod 15 is pressed to one side, its wedge surface 19 cooperates with the inclined slide groove 18 to drive the locking slider 14 to move backward. At this time, the locking protrusion 17 and the toothed positioning plate 16 are released, and the first leg 5 can rotate an angle to release the pressure on the locking slider driving rod 15. The locking slider 14 is reset under the action of the compression spring. At the same time, the locking slider 14 has a reverse thrust on the locking slider driving rod 15, pushing the locking slider driving rod 15 to the initial position. The inclination angle of the first leg 5 is adjusted according to the different positions at which the locking protrusion 17 is engaged with the toothed positioning plate 16 .

[0051] Furthermore, a group of vertical guide blocks 30 are arranged in a circular array on the telescopic upright sleeve 21, and a group of telescopic upright sleeve guide grooves 31 matched with the vertical guide blocks 30 and a rotational positioning sleeve positioning groove 32 matched with the wedge-shaped slider 25 are respectively provided on the guide positioning shaft 20.

[0052] The cooperation between the vertical guide block 30 and the telescopic upright sleeve guide groove 31 can prevent the telescopic upright sleeve 21 from rotating and causing the corrugated guide groove 27 to be misaligned, and the telescopic upright sleeve 21 can only move up and down, and its movement is stable.

[0053] After the wedge-shaped sliding block 25 moves into the locating groove 32 of the rotatable locating sleeve, the rotatable locating sleeve 22 cannot rotate but can only move up and down, so that the rotatable locating sleeve 22 can be accurately rotated and positioned.

[0054] Furthermore, a plane bearing 35 is provided on the mandrel 23 in the rotating positioning sleeve 22, and the rotating positioning sleeve 22 rotates on the mandrel 23 through the plane bearing 35. The plane bearing 35 makes the rotating positioning sleeve 22 rotate more smoothly and stably.

[0055] The telescopic upright sleeve 21 is integrally formed by a core shaft mounting part and a positioning shaft mounting part. The core shaft mounting part is provided with a core shaft 23 mounting hole. The pressing handle 28 is hinged on the core shaft through a pin shaft. The core shaft mounting part 33 is provided with a pin shaft avoidance long hole. The positioning shaft mounting part is a double-layer cylindrical structure. The rotating positioning sleeve 22 is located in the inner cylinder of the double-layer cylindrical structure, and the guide positioning shaft 20 is located in the outer cylinder of the double-layer cylindrical structure.
