Description

TECHNICAL FIELD

[0001] The present application relates to the field of camera equipment, in particular to a tripod for camera equipment. BACKGROUND

[0002] In the current camera industry, a tripod is a very common camera equipment support device, which has the advantage of being easy to carry. In order to meet the requirements of rotating shooting, close-up shooting, long shot switching shooting, and dynamic follow-up shooting, most of the tripods on the market have the function of freely swinging in multiple directions with the support point as the axis. However, when long-time still shooting is required, the tripod also needs to be fixed. Therefore, a locking mechanism is needed to complete the switching between free swinging and locking. Most of the locking mechanisms on the market use screw locking, which is time-consuming and cumbersome and cannot be completed in one step. Especially when the free swinging and locking states are frequently switched, it will be particularly cumbersome and time-consuming, and may even cause the best shooting opportunity to be missed.

[0034] The application will be described in detail below with reference to the drawings and specific embodiments, so that the technical solutions of the application and their beneficial effects are more clearly and comprehensively understood. It can be understood that the drawings are provided only for reference and illustration, and are not intended to limit the application. The dimensions shown in the drawings are only for clear description, and do not limit the proportional relationship.

[0035] Reference Figure 1 And Figure 2 A tripod for supporting a camera device, such as a video camera, a still camera, etc. The tripod includes a mounting platform 500, a base 300 spaced apart from the mounting platform 500, and a locking mechanism 100 connecting the mounting platform 500 and the base 300. In this embodiment, the mounting platform 500 can be connected to a pan-tilt head through a connecting rod 91 (see Figure 10 ) to form a single tripod, or can be directly connected to a pan-tilt head to form a low-shooting structure. The locking mechanism 100 includes a support rod 10, a sliding groove guide lock 30 sleeved on the support rod 10, a catch pin 40 connected to the support rod and cooperating with the sliding groove guide lock 30, a resilient member 50 located between the base 300 and the sliding groove guide lock 30, and a driving member 60 pivoted on the support rod 10. One end of the support rod 10 is rotatably connected to the mounting platform 500 through a universal ball 20, and the locking mechanism 100 is configured to move the catch pin 40 relative to the sliding groove guide lock 30 and position it to a first fixed position or a second fixed position by pressing the driving member 60. At the first fixed position, the top end of the sliding groove guide lock 30 abuts against the mounting platform 500 to be fixed, and at the second fixed position, the sliding groove guide lock 30 is released from the fixation.

[0036] The top end of the support rod 10 is fixedly connected to the universal ball 20 and connected to the mounting platform 500 through the universal ball 20. The universal ball 20 is movably received in the mounting platform 500, so that the mounting platform 500 is rotatably connected to the locking mechanism 100.

[0037] When the sliding guide lock 30 is moved to its top end and is fixed against the mounting platform 500, the locking pin 40 slides in the sliding guide lock 30 to a first fixed position. At this time, the foot stool is in a locked state. When the sliding guide lock 30 is released, the locking pin 40 slides in the sliding guide lock 30 to a second fixed position. At this time, the foot stool is in a rotatable swing state. The operator can press the driving member 60 to cycle the foot stool between the locked and unlocked (i.e., rotatable swing) states, which is convenient, simple and fast. In this embodiment, the locking mechanism 10 is a locking mechanism, i.e., the locking mechanism 10 can be locked in a vertical orientation. Specifically, when the base 300 is supported on the ground, in the locked state of the locking mechanism 10, the locking mechanism 10 is oriented in a vertical direction, i.e., extends in a direction perpendicular to the ground. In addition, the driving member 60 in this embodiment is a foot pedal.

[0038] Specifically, the mounting platform 500 can be recessed in the middle of the bottom end of the locking mechanism 100 to form a receiving cavity 501 for receiving the universal ball 20 therein. Preferably, the receiving cavity 501 is substantially spherical to match the shape of the universal ball 20. The bottom end of the receiving cavity 501 is opposite to the top end of the sliding guide lock 30. The bottom end of the receiving cavity 501 is formed with an inclined limiting surface 503, and the top end of the sliding guide lock 30 is formed with an abutting surface 331 that cooperates with the limiting surface 503, and the limiting surface 503 can abut against the abutting surface 331.

[0039] Specifically, the limiting surface 503 is an annular surface and is formed around to form a cavity in communication with the receiving cavity 501. Preferably, the limiting surface 503 is a truncated conical surface, and the aperture of the cavity gradually increases in the vertical direction towards the locking mechanism 100, i.e., the cavity forms a horn-shaped opening. Please further refer to Figures 3 to 5, the chute guide lock 30 is a column in whole, comprising a main body part 31 and an extension part 33 protruding from the middle of the top surface of the main body part 31. The diameter of the extension part 33 is smaller than that of the main body part 31. A step 35 is formed at the joint of the main body part 31 and the extension part 33 for the driving member 60 to abut against. The abutment surface 331 is formed at the top end of the extension part 33 away from the main body part 31. The abutment surface 331 is an annular surface and surrounds a cavity. Preferably, the abutment surface 331 is an inclined surface, and the diameter of the top end of the extension part 33 forming the abutment surface 331 gradually increases from the top end downwards, i.e., the top end of the extension part 33 is slightly convergent. The outer diameter of the abutment surface 331 is greater than the minimum diameter of the opening of the limiting surface 503 and smaller than the maximum diameter of the opening, so as to ensure that the abutment surface 331 can abut against the limiting surface 503.

[0040] The extension part 33 is provided with a longitudinal chute 333 along its length direction. The driving member 60 is pivotally connected to the support rod 10 through a pivot shaft 70. The pivot shaft 70 sequentially passes through the driving member 60, the chute 333 of the extension part 33 of the chute guide lock 30, and can slide up and down along the chute 333 when the chute guide lock 30 is moved by the abutment of the elastic member 50. In the embodiment, the driving member 60 has two installation arms arranged at intervals, and the two installation arms are respectively located at opposite sides of the support rod 10. When the pivot shaft 70 sequentially passes through one of the installation arms, the support rod 10 and the chute 333, the pivot shaft 70 is inserted into the other installation arm. It can be understood that in other embodiments, the number of installation arms is one.

[0041] Please also refer to Figure 5 The inner surface of the chute guide lock 30 is formed with a guide groove 335. The guide groove 335 has a first temporary limiting position 3351 and a second temporary limiting position 3353 arranged at intervals towards the top end of the installation platform 500. A positioning position 3355 is formed below the first temporary limiting position 3351 and the second temporary limiting position 3353. The catch pin 40 slides along the guide groove 335 and can abut against the first temporary limiting position 3351 and the second temporary limiting position 3353 or hook with the positioning position 3355.

[0042] The longitudinal section of the first temporary position 3351 and the second temporary position 3353 is inverted V-shaped, and the opening of the V-shaped is inclined downward toward the first direction. The top end of the second temporary position 3353 exceeds the top end of the first temporary position 3351. The positioning position 3355 is located below the connection between the first temporary position 3351 and the second temporary position 3353, and is relatively closer to one side of the second temporary position 3353. The longitudinal section of the positioning position 3355 is approximately V-shaped, and the opening is upward toward the second direction. The first direction and the second direction are opposite.

[0043] The longitudinal section of the bottom end of the guide groove 335 connecting the first temporary position 3351 and the second temporary position 3353 is Y-shaped, and the top end of the Y-shaped is connected to the first temporary position 3351 and the second temporary position 3353, respectively. The end connected to the first temporary position 3351 is located above the end connected to the second temporary position 3353.

[0044] The elastic member 50 is sleeved on the support rod 10 and one end is accommodated in the main body 31. The elastic member 50 is used to elastically abut against the main body 31. In this embodiment, the elastic member 50 is a spring.

[0045] The catch 40 includes a fixed part 41, a connecting part 43 extending from the fixed part 41, and a catch hook 45 located at one end of the connecting part 43. The fixed part 41 is pivoted on the support rod 10. The catch hook 45 is accommodated in the sliding groove lock 30 and is used to hook with the sliding groove lock 30. The catch 40 can be bent from a linear material. In this embodiment, the fixed part 41 is annular and is pivoted on the support rod 10 by a screw 80 and can rotate relative to the screw 80. The catch hook 45 and the fixed part 41 are located at opposite ends of the connecting part 43, respectively, and are arranged at an angle. The catch hook 45 is used to cooperate with the guide groove 335.

[0046] The base 300 includes a main body 301 connected to the support rod 10 and a plurality of legs 303 arranged around the circumference of the main body 301. In this embodiment, the number of legs 303 is three, and the three legs 303 are uniformly distributed in the circumferential direction.

[0047] In this application, the sliding groove lock 30 is pushed upward by the elastic force of the elastic member 50 to move toward the mounting platform 500. When the abutting surface 331 on the extension 33 abuts against and fixes the limiting surface 503 on the mounting platform 500, at this time the catch hook 45 of the catch 40 slides along the sliding groove lock 30 to the first fixed position, and the catch hook 45 is located at the Y-shaped bottom of the guide groove 335, at this time the mounting platform 500 is locked and cannot rotate and swing.

[0048] When the operator presses the driving member 60 downward, the driving member 60 presses the step 35 plane on the sliding groove lock 30 downward, drives the sliding groove lock 30 to slide downward along the support rod 10, and the clamping hook 45 moves right upward along the Y-shaped bottom of the guide groove 335 to the first temporary limiting position 3351. At this time, because the clamping hook 45 abuts against the top end of the first temporary limiting position 3351, the sliding groove lock 30 cannot continue to move downward, that is, the driving member 60 cannot continue to move downward, and the operator completes one driving. At this time, the elastic member 50 is compressed by the sliding groove lock 30. Then the operator releases the driving member 60. At this time, the sliding groove lock 30 moves upward under the action of the upward elastic force of the elastic member 50, the clamping hook 45 moves downward from the first temporary limiting position 3351 along the sliding groove 333 to the positioning position 3355 at the bottom of the guide groove 335 and abuts against the bottom of the positioning position 3355. At this time, because the clamping hook 45 is forced, the sliding groove lock 30 cannot continue to move upward and is fixed at this position. At this time, the sliding groove lock 30 is separated from the mounting platform 500, the locking of the mounting platform 500 is released, and the mounting platform 500 can rotate and swing around the ball center of the universal ball 20.

[0049] When the operator presses the driving member 60 again, the driving member 60 moves downward and presses the step 35 plane on the sliding groove lock 30, drives the sliding groove lock 30 to slide downward, and the clamping hook 45 moves from the positioning position 3355 to the second temporary limiting position 3353 along the guide groove 335 and abuts against the top of the second temporary limiting position 3353. At this time, because the clamping hook 45 is forced, the sliding groove lock 30 cannot continue to move downward, that is, the driving member 60 cannot continue to move downward, and the operator completes one driving of the driving member 60. The operator releases the driving member 60. At this time, the sliding groove lock 30 continues to move upward under the action of the upward elastic force of the elastic member 50, the clamping hook 45 moves downward from the second temporary limiting position 3353 to the bottom of the Y-shaped sliding groove 333 along the guide groove 335. At this time, the abutting surface 331 on the sliding groove lock 30 abuts against and fixes the limiting surface 503 on the mounting platform 500. At this time, the mounting platform 500 is locked and cannot rotate and swing, and the clamping hook 45 is not forced at the bottom of the Y-shaped sliding groove 333. In this application, the operator presses the driving member 60 circularly, makes the clamping hook 45 move in the guide groove 335, and makes the foot support quickly and circularly switch between the upright locking and the rotating and swinging, without using both hands, which is convenient, simple and fast.

[0050] Please refer to Figures 6 to 9The tripod for camera equipment of another embodiment of the present application is similar to the tripod for camera equipment of the previous embodiment, and the difference is that the present embodiment further comprises a locking assembly 700. The locking assembly 700 is slidably sleeved on the periphery of the mounting platform 500 and is used to act on the universal ball 20a. When the tripod is in an unlocked state, the mounting platform 500 can swing relative to the universal ball 20a, and the locking assembly 700 is used to lock the universal ball 20a at a desired angle, so that the mounting platform 500 is fixed relative to the universal ball 20a, thereby enabling the mounting platform 500 to be fixed at a specific position.

[0051] Specifically, the mounting platform 500 is provided with an external thread on the outer peripheral surface of the bottom end of the locking mechanism to form a threaded section 502. The threaded section 502 is recessed radially inward in the middle of the outer surface of the mounting platform 500 to form a receiving groove 504. In the present embodiment, the receiving groove 504 is located in the threaded section 502.

[0052] The locking assembly 700 comprises a locking block 705 that is partially movably received in the receiving groove 504, a locking sleeve 703 that is sleeved on the bottom end of the mounting platform 500 and is threadedly connected thereto, and a locking member 707 that is arranged in the receiving cavity 501 of the mounting platform 500 and is located at the bottom end of the universal ball 20a. The inner side of the locking block 705 can protrude into the mounting platform 500 from the receiving groove 504 and abut against the locking member 707. The locking assembly 700 is configured to drive the locking sleeve 707 to move along the longitudinal direction of the mounting platform 500, thereby pushing the locking block 705 to move inward, and further making the locking block 705 abut against the locking member 707 upward until the locking member 707 locks the universal ball 20a.

[0053] Specifically, the mounting platform 500 is provided with a through hole penetrating through the wall portion thereof in the region where the receiving groove 504 is located. The inner side portion of the locking block 705 can extend into the receiving cavity 501 via the receiving groove 504, and the inner side portion of the locking block 705 that extends into the receiving cavity 501 is located below the locking member 707. The outer side of the locking block 705 protrudes radially out of the receiving groove 504. Rotating the locking sleeve 703 causes it to move upward along the bottom end of the mounting platform 500, thereby pushing the locking block 705 to move inward, and further making the locking block 705 abut against the locking member 707 upward until the locking member 707 locks the universal ball 20a, thereby achieving the fixation of the mounting platform 500 relative to the universal ball 20a.

[0054] Preferably, the locking assembly 700 of the present embodiment further comprises a resilient member 701 for providing an outward resilient force to the locking block 705 to help the locking block 705 to reset when the locking is released. In the present embodiment, the resilient member 701 is arranged in the receiving groove 504 with one end abutting the groove wall of the receiving groove 504 and the other end abutting the corresponding locking block 705. In the present embodiment, the resilient member 701 is a coil spring.

[0055] In the present embodiment, the locking sleeve 703 is a continuous annular ring. The locking sleeve 703 comprises a locking section 7031 and a guiding section 7033 along its axial direction. The locking section 7031 has a uniform inner diameter and its inner surface is provided with internal threads for mating with the external threads of the mounting platform 500. The guiding section 7033 extends upwardly from the top end of the locking section 7031 and its inner diameter gradually increases from the bottom end connected with the locking section 7031 to the top end. In this way, the inner surface of the guiding section 7033 is a conical surface which inclines outwardly from bottom to top. When the locking sleeve 703 is assembled to the periphery of the mounting platform 500, a gap 7034 is formed between the inner surface of the guiding section 7033 of the locking sleeve 703 and the outer surface of the mounting platform 500. Since the inner surface of the guiding section 7033 is an inclined surface, the width of the gap 7034 gradually increases from bottom to top.

[0056] It can be understood that in other embodiments, the locking sleeve 703 can also be arranged as spaced apart arc-shaped segments as long as it can cooperate with the locking block 705.

[0057] In order to protect the locking sleeve 703 and increase the hand feeling of the operator, preferably, a protective sleeve 708 can be sleeved on the locking sleeve 703. The protective sleeve 708 is a leather sleeve or a plastic sleeve.

[0058] The locking block 705 comprises a connecting section 7051 and a pushing section 7053 extending upwardly from the connecting section 7051. The connecting section 7051 is received in the receiving groove 504 and abuts the corresponding resilient member 701. In the present embodiment, the connecting section 7051 is substantially square-shaped.

[0059] In order to more stably connect the resilient member 701, in the present embodiment, preferably, the mounting platform 500 is further recessed at the bottom of the receiving groove 504 to form a connecting hole 505 which is a blind hole, and the inner surface of the connecting section 7051 is also recessed to form a receiving hole 7052, and the opposite ends of the resilient member 701 are respectively received in the connecting hole 505 and the receiving hole 7052. In other embodiments, a fixing column can also be arranged on the bottom of the receiving groove 504 and / or the connecting section 7051 of the locking block 705, and the end of the resilient member 701 is sleeved on the fixing column to form a stable connection and positioning.

[0060] The pushing section 7053 has an inclined pushing surface 7054 facing the locking member 707, which extends upward and outward from the bottom end of the connecting section 7051 to abut against the locking member 707. In this embodiment, the pushing section 7053 is substantially a wedge-shaped block, which is located at the upper portion of the receiving groove 504 and opposite to the through hole. The bottom surface of the pushing section 7053 connects the top surface of the connecting section 7051, and the outer side of the pushing section 7053 protrudes from the receiving groove 504 and is located in the gap 7034 between the locking sleeve 703 and the mounting platform 500. The outer side surface of the pushing section 7053 faces the inner surface of the guiding section 7033, and the top surface of the pushing section 7053 connects the outer side surface and the top end of the pushing surface 7054. The inner side end of the pushing section 7053 is beyond the inner side end of the connecting section 7051. In this embodiment, the width of the bottom surface of the pushing section 7053 is greater than the width of the connecting section 7051. Specifically, the width of the pushing section 7053 gradually decreases from bottom to top. Therefore, when the locking sleeve 703 is rotated to move upward, the inclined inner surface of the guiding section 7033 of the locking sleeve 703 abuts against the locking block 705 inward, so that the locking block 705 moves radially inward to push the locking member 707 upward.

[0061] In this embodiment, the outer side surface of the pushing section 7053 is an inclined surface, which inclines outward and upward from the top end of the outer side surface of the connecting section 7051. Preferably, the outer side surface of the pushing section 7053 is complementary to the inner surface of the guiding section 7033 of the locking sleeve 703, so as to increase the contact area between the two surfaces and make the force on the locking block more uniform during pushing. Alternatively, the pushing surface 7054 is an arc surface or a flat surface. In this embodiment, the pushing surface 7054 is an arc surface, which is concave inward along the circumference of the locking sleeve 703, so as to better fit into the receiving groove 504 of the mounting platform 500 and accommodate the circular outer periphery of the mounting platform 500.

[0062] In this embodiment, three receiving grooves 504 are uniformly arranged along the circumference of the threaded section 502 of the mounting platform 500, and three locking blocks 705 are respectively accommodated in the corresponding receiving grooves 504. Each receiving groove 504 is provided with two connecting holes 505. Two elastic members 701 are respectively accommodated in the two connecting holes 505 of one receiving groove 504 and cooperate with the corresponding locking block 705.

[0063] It can be understood that, in other embodiments, the receiving groove 504 can be two, which are symmetrically located on opposite sides of the bottom end of the mounting platform 500; the receiving groove 504 can also be one or multiple spaced apart grooves, and the number thereof can be selected as needed. Correspondingly, the number and structure of the elastic members can also be adjusted as needed.

[0064] The locking member 707 has a locking surface 7071 facing the universal ball 20a and a joint surface 7073 for cooperating with the pushing surface 7054 of the locking block. The locking surface 7071 is adapted to the universal ball 20a for being attached to the universal ball 20a. The joint surface 7073 extends outwardly and upwardly from the bottom end of the locking member 707.

[0065] Specifically, the locking member 707 is in the shape of a ring, and the inner diameter of the locking member 707 gradually decreases from top to bottom. The opening at the bottom of the locking member 707 is smaller than the diameter of the universal ball 20a, so that the universal ball 20a can be partially accommodated in the locking member 707 without being detached from the opening. The joint surface 7073 is formed on the outer wall of the bottom of the locking member 707, and extends radially outwardly and upwardly from the middle of the locking member 707, so as to cooperate with the inclined pushing surface 7054 of the locking block 705. Therefore, when the locking block 705 is pushed by the locking sleeve 703 to move radially inwardly, the joint surface 7073 is gradually pushed upwardly by the pushing surface 7054 due to the cooperation between the pushing surface 7054 and the joint surface 7073, so that the locking member 707 is pushed upwardly until the universal ball 20a is clamped to be fixed relative to the universal ball 20a.

[0066] Preferably, the inner surface of the locking member 707 is in the shape of a concave arc surface as the locking surface 7071 for cooperating with the universal ball 20a.

[0067] To avoid abrasion of the universal ball 20a, the foot stool further comprises a gasket 80 fixed at the bottom end of the universal ball 20a, and the locking member 707 is attached to the outer side of the gasket 80. The gasket 80 is adapted to the shape of the bottom end of the universal ball 20a. Preferably, the peripheral edge of the bottom end of the universal ball 20a is recessed inwardly to accommodate the gasket 80, so as to facilitate quick alignment of the gasket 80 during installation, and to reduce the height difference between the outer peripheral edge of the gasket 80 after being fixed and the rest of the surface of the universal ball 20a. The gasket 80 is fixed to the universal ball 20a by a screw 90, which is inserted through the through hole at the bottom end of the gasket 80 and cooperates with the screw hole of the universal ball 20a in the present embodiment.

[0068] Preferably, the locking assembly 700 further comprises a limiting member 709 fixed at the bottom end of the threaded section 502 of the mounting platform 500, for preventing the locking sleeve 703 from being unscrewed from the threaded section 502. In the present embodiment, the limiting member 709 is a circlip.

[0069] Please refer to Figure 10In use, the holder can be connected to the stand by a connecting rod 91. Specifically, the holder is fixed to the top end of the connecting rod 91, and the bottom end of the connecting rod 91 is fixed to the top end of the mounting platform 500, i.e. the end away from the gimbal ball 20a. The camera equipment can be fixed to the holder, so as to perform long shot. It can be understood that when performing close shot, the connecting rod 91 can not be used, and the holder can be directly fixed to the top end of the mounting platform 500, and the camera equipment can be fixed to the holder, so as to form a low shot structure.

[0070] In the embodiment, when it is needed to fix the gimbal ball 20a, the locking sleeve 703 is rotated upward, so that the inner surface of the guide section 7033 of the locking sleeve 703 moves along the outer surface of the connecting section 7051 of the locking block 705 to the outer surface of the pushing section. Since the inner diameter of the guide section 7033 gradually decreases from top to bottom, the guide section 7033 pushes the locking block 705 to move inward, and the pushing surface 7054 of the pushing section 7053 pushes the locking member 707 along the inclined surface 7073 to move toward the gasket 80, until the locking surface 7071 of the locking member 707 abuts against the outer periphery of the gasket 80. In this way, the locking member can be fixed relative to the gimbal ball 20a, so that the mounting platform 500 can be fixed at a specific position.

[0071] The above merely describes the preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any simple change or equivalent replacement of the technical solutions within the technical scope disclosed in the present application can be obtained by those skilled in the art, and all fall within the protection scope of the present application.
