[0045] An embodiment of the present utility model provides a control handle 100 of a photography support frame, and the control handle 100 can be used to lock or unlock the support leg locking assembly of the photography support frame.

[0046] Refer to Figures 2 to 5 , the control handle 100 includes:

[0047] A handle shaft 110, which is hollow inside;

[0048] A handle body 120, which is rotatably sleeved on the handle shaft 110;

[0049] A limiting pin 130 is slidably inserted through the handle shaft 110;

[0050] Wherein, one of the limiting pin 130 and the handle body 120 is provided with a clamping portion 10, and the other is provided with a card slot 20 adapted to the clamping portion 10. The limiting pin 130 can slide along the axial direction of the handle shaft 110, so that the clamping portion 10 is snapped into the card slot 20 to limit the rotation of the handle body 120, or the clamping portion 10 is withdrawn from the card slot 20 to allow the handle body 120 to rotate.

[0051] The control handle 100 involved in this embodiment is used as a component of the photographic support frame and can be linked with the support foot locking assembly of the photographic support frame to lock or unlock the support foot locking assembly of the photographic support frame. That is, the user can operate this control handle 100 to lock the support foot 300 by the support foot locking assembly. In the locked state, the support foot 300 cannot be telescoped; or, to unlock the support foot 300 by the support foot locking assembly. In the unlocked state, the user can operate the support foot 300 to telescope to adjust its support height, and lock it again after adjustment.

[0052] Specifically, the photographic support frame may include a receiving seat 200 and a plurality of support feet 300 connected to the receiving seat 200 and used to support the receiving seat 200. The receiving seat 200 is used to install photographic equipment, and the photographic equipment may be a camera or the like. The support foot locking assembly is correspondingly arranged at the support foot 300 and is used to clamp or release the support foot 300. The control handle 100 may be installed on the receiving seat 200 and is correspondingly linked with the support foot locking assembly. The control handle 100 may be a hydraulic handle, an electric control handle, etc. The type of the handle of the control handle 100 is not limited in this embodiment.

[0053] In the control handle 100, the handle shaft 110 may be a hollow shaft with a shaft hole formed therein. The limiting pin 130 extends into the shaft hole and forms a sliding fit with the handle shaft 110, that is, the limiting pin 130 can slide along the axial direction of the handle shaft 110 on the handle shaft 110. The handle body 120 is generally in the shape of a grip and can be held by the user for manipulation or carried by hand. One end of the handle body 120 is sleeved on the handle shaft 110 and forms a rotational fit with the handle shaft 110. In this way, the handle body 120 can rotate relative to the handle shaft 110 to adjust the angle / position.

[0054] A clamping structure of the clamping portion 10 and the card slot 20 is provided between the limiting pin 130 and the handle body 120. Specifically, the clamping portion 10 may be provided on the limiting pin 130 and the card slot 20 may be provided on the handle body 120; or, the card slot 20 may be provided on the handle body 120 and the clamping portion 10 may be provided on the limiting pin 130.

[0055] Through the provided clamping structure, the limit pin 130 can lock or unlock the handle body 120. In the locked state, the rotation of the handle body 120 is restricted, and in the unlocked state, the handle body 120 can rotate.

[0056] The locking process is as follows: The limit pin 130 moves axially along the handle shaft 110 towards the first direction, correspondingly causing the clamping portion 10 to move towards the card slot 20 and gradually engage with the card slot 20 to lock the handle body 120.

[0057] The unlocking process is as follows: The limit pin 130 moves axially along the handle shaft 110 towards the second direction opposite to the first direction, correspondingly causing the clamping portion 10 to move away from the card slot 20 and gradually withdraw from the card slot 20 to unlock the handle body 120.

[0058] In this embodiment, the handle body 120 of the control handle 100 can rotate relative to the handle shaft 110 to be unfolded or folded, and can be fixed to a corresponding angle / position through the clamping cooperation between the clamping portion 10 provided between the limit pin 130 and the handle body 120 and the card slot 20. That is, the control handle 100 of the present utility model is a foldable handle, which can be converted from the original horizontal unfolded state to the vertical folded state for storage, thereby reducing the occupied horizontal space and improving the convenience of carrying the photography support frame.

[0059] Among them, the adjustable angle range of the handle body 120 can be from 0° to 90°. During use, the user can adjust the angle of the handle body 120 to 0° (equivalent to vertical) to switch the control handle 100 to the folded state for storage; or, the angle of the handle body 120 can be adjusted to 90° (equivalent to horizontal) to switch the control handle 100 to the unfolded state for convenient operation; or, the angle of the handle body 120 can be adjusted to 45° to switch the control handle 100 to the semi-unfolded state for convenient hand-held. The application scenarios described above are only exemplary and not restrictive.

[0060] In some embodiments, refer to Figure 4 and Figure 5, the control handle 100 further includes: a reset member 140 disposed on the handle shaft 110, and the reset member 140 is used to apply a resetting force to the limit pin 130. Specifically, after the angle / position adjustment of the handle body 120 is completed, when the external force acting on the limit pin 130 is removed, the limit pin 130 can be driven to slide axially along the handle shaft 110 and automatically reset to the initial position under the action of the reset member 140, and the clamping portion 10 is correspondingly clamped in the card slot 20, thereby realizing the automatic locking of the handle body 120, which is convenient to use. Among them, the reset member 140 can be an elastic member, such as a spring, a tension spring, etc., and the limit pin 130 is reset by the elastic force of the elastic member. In addition, when the handle body 120 is in the locked state, the force applied by the reset member 140 to the limit pin 130 can keep the limit pin 130 in the initial position, correspondingly forming a stable clamping fit between the clamping portion 10 and the card slot 20, ensuring the stability of the locking of the handle body 120.

[0061] In some embodiments, referring to Figure 5 and Figure 6 , a clamping portion 10 is provided on the limit pin 130, and a card slot 20 is provided on the handle body 120. When the handle body 120 is locked, the limit pin 130 moves axially along the handle shaft 110 toward the first direction. During this movement, the clamping portion 10 on the limit pin 130 gradually exits from the card slot 20 on the handle body 120, and after completely exiting, the handle body 120 is unlocked; when the handle body 120 is unlocked, the limit pin 130 moves axially along the handle shaft 110 toward the second direction opposite to the first direction. During this movement, the clamping portion 10 on the limit pin 130 gradually snaps into the card slot 20 on the handle body 120, thereby realizing the locking of the handle body 120.

[0062] In some embodiments, referring to Figure 5 and Figure 6 , the clamping portion 10 is constructed at one end of the limit pin 130 and protrudes from the side wall of the limit pin 130; one end of the handle body 120 has a sleeved portion 121 sleeved on the handle shaft 110, and the card slot 20 is constructed on the side wall of the sleeved portion 121 opposite to the clamping portion 10. Specifically, when the handle body 120 rotates relative to the handle shaft 110, the sleeved portion 121 at one end of the handle body 120 rotates correspondingly on the handle shaft 110, and the card slot 20 provided on the side wall of the sleeved portion 121 changes its position as it rotates, and can be aligned with the clamping portion 10 on the limit pin 130. After the handle body 120 rotates to the pre-adjusted angle / position, the card slot 20 on the side wall of the sleeved portion 121 is aligned with the clamping portion 10 on the limit pin 130. By moving the limit pin 130 axially along the handle shaft 110, the clamping portion 10 is snapped into the card slot 20 to realize the locking of the handle body 120.

[0063] In some embodiments, referring to Figure 5 and Figure 6, one end of the handle 110 is configured with an escape opening K extending along its axial direction, and the escape opening K is used for the clamping portion 10 to pass through and form an escape for the movement of the clamping portion 10. Specifically, along the axial direction of the handle 110, the escape opening K constructed at one end of the handle 110 extends toward the other end thereof, and the extension length is not limited and can be set according to actual needs. When the limit pin 130 is assembled on the handle 110, the clamping portion 10 on the limit pin 130 passes through the escape opening K of the handle 110 and is accommodated in the escape opening K of the handle 110. When the handle body 120 is unlocked or locked, the limit pin 130 slides along the axial direction of the handle body 120, and the clamping portion 10 thereon moves at the escape opening K to correspondingly withdraw from or enter the clamping slot 20. Among them, one or more escape openings K can be provided, and their number can be set according to the number of clamping portions 10. For example, three clamping portions 10 are provided, and three avoidance openings K are provided correspondingly, and each clamping portion 10 passes through a corresponding avoidance opening K. In this embodiment, by providing the avoidance opening K on the handle shaft 110 to accommodate the clamping portion 10 on the limit pin 130, the axial design size can be reduced, thereby improving the compactness of the overall structure.

[0064] In some embodiments, reference Figure 5 and Figure 6 There are multiple clamping parts 10, and the multiple clamping parts 10 are arranged at intervals in the axial direction of the handle shaft 110; there are multiple clamping slots 20, and the multiple clamping slots 20 are arranged at intervals in the axial direction of the handle shaft 110 and correspond to the positions of the multiple clamping parts 10. The number of clamping parts 10 and the number of clamping slots 20 can be the same, for example, there are six clamping parts 10 and six clamping slots 20, and the six clamping parts 10 can be correspondingly inserted into the six clamping slots 20; or the number of clamping parts 10 and the number of clamping slots 20 can be different, such as Figure 5 and Figure 6 As shown, for example, there are three clamping parts 10 and six clamping slots 20, and the three clamping parts 10 can be correspondingly clamped into three of the six clamping slots 20. By clamping and cooperating with the plurality of clamping parts 10 and the plurality of clamping slots 20, the cooperation between the limit pin 130 and the handle body 120 can be made tighter and more stable, thereby ensuring the stability of the locking of the handle body 120.

[0065] In some embodiments, reference Figures 2 to 6 The control handle 100 further includes: an unlocking key 150, which is connected to the limiting pin 130 along the axial direction of the handle shaft 110, and the unlocking key 150 is used to drive the limiting pin 130 to slide when subjected to an external force.

[0066] The unlocking key 150 is provided for the user to manually operate, so as to drive the limit pin 130 to slide and unlock the handle body 120. Specifically, in the axial direction of the handle shaft 110, the unlocking key 150 and the limit pin 130 are connected to each other, and the unlocking member and the limit pin 130 can be detachably connected, and the connection form includes screw connection, buckle connection, etc. In this way, when the unlocking key 150 is moved by an external force, the limit pin 130 can slide with the unlocking key 150.

[0067] The unlocking key 150 may be an unlocking button. The user may press the unlocking key 150 so that the unlocking key 150 drives the limit pin 130 to slide, thereby causing the clamping portion 10 to exit the clamping slot 20 to unlock the handle 120, and the handle 120 may then be rotated to adjust the angle. In addition, the unlocking key 150 may also be an unlocking pull key, which is not limited in this embodiment. When the user loosens / releases the unlocking key 150, the limit pin 130 is driven to reset under the action of the reset member 140. During the reset process of the limit pin 130, the clamping portion 10 is correspondingly clamped into the clamping slot 20 to lock the handle 120.

[0068] In some embodiments, reference Figures 4 to 6 The unlocking key 150 extends into the handle 110 to connect with the limit pin 130, and the inner wall of the handle 110 is configured with a step J;

[0069] The reset member 140 includes a reset spring, which is sleeved on the limit pin 130 , with one end of the reset spring abutting against the unlocking key 150 , and the other end of the reset spring abutting against the step J.

[0070] Specifically, when the unlocking key 150 is subjected to an external force and moves along the axial direction of the handle shaft 110 toward the inside of the handle shaft 110, the corresponding reset spring is compressed. At the same time, the limit pin 130 slides with the unlocking key 150, and the clamping part 10 gradually withdraws from the clamping slot 20. After the complete withdrawal, the handle body 120 is unlocked and can rotate; when the external force on the unlocking key 150 is removed, the reset spring stretches to drive the unlocking key 150 to move along the axial direction of the handle shaft 110 toward the outside of the handle shaft 110, thereby driving the limit pin 130 to slide, the clamping part 10 gradually clamps into the clamping slot 20, and the handle body 120 is locked and cannot rotate. In this embodiment, the unlocking key 150, the limit pin 130 and the spring used by the reset member 140 are closely arranged on the handle shaft 110, with a compact structure and a stable connection.

[0071] In some embodiments, reference Figures 4 to 6 The limiting pin 130 is provided with a mounting hole 131 extending axially from an end surface of one end thereof toward the other end, and the other end of the limiting pin 130 is provided with a connecting hole 132 communicating with the mounting hole 131;

[0072] The mounting hole 131 is provided with a fastener G, and the fastener G passes through the connection hole 132 to be connected to the unlocking key 150.

[0073] Wherein, the fastener G can be a screw, and the unlocking key 150 is provided with a threaded hole adapted to the fastener G. When the unlocking key 150 is docked with the limit pin 130, its threaded hole is aligned with the connection hole 132 of the limit pin 130. The fastener G can be passed through the connection hole 132 through the mounting hole 131 to perform threaded cooperation with the threaded hole on the unlocking key 150, thereby fastening the limit pin 130 and the unlocking key 150 together, with stable connection and convenient disassembly and assembly.

[0074] In some embodiments, referring to Figure 5 and Figure 6 One of the docking surfaces of the unlocking key 150 and the limit pin 130 is constructed with a slot 30, and the other is constructed with a plug-in portion 40 adapted to the slot 30. The plug-in portion 40 is in plug-in cooperation with the slot 30 so that the unlocking key 150 and the limit pin 130 are relatively fixed in the circumferential direction.

[0075] Specifically, it can be that the docking surface of the unlocking key 150 is constructed with a slot 30, and the docking surface of the limit pin 130 is constructed with a plug-in portion 40, or it can also be that the docking surface of the limit pin 130 is constructed with a slot 30, and the docking surface of the unlocking key 150 is constructed with a plug-in portion 40. Among them, the slot 30 is recessed on the docking surface of its constructed object (such as the unlocking key 150), and the plug-in portion 40 is protruded on the docking surface of its constructed object (such as the limit pin 130). When the unlocking key 150 and the limit pin 130 are assembled, their docking surfaces are docked, and the plug-in portion 40 is correspondingly inserted into the slot 30 to form a fit.

[0076] Among them, the slot 30 can be a non-circular slot, such as a square slot, a triangular slot, etc., including but not limited to this. The contour shape of the plug-in portion 40 is the same as that of the slot 30. When it is inserted into the slot 30, it correspondingly makes the unlocking key 150 and the limit pin 130 relatively fixed in the circumferential direction, that is, the unlocking key 150 and the limit pin 130 cannot rotate relative to each other in the direction around the docking axis, which helps to improve the connection stability. And it can realize the positioning during connection, which helps to improve the assembly efficiency.

[0077] In some embodiments, the control handle 100 further includes:

[0078] A handle base 160, which is constructed with a receiving cavity 161 and an opening 162 communicating with the receiving cavity 161;

[0079] Wherein, the handle shaft 110 is installed in the handle base 160 and is located in the receiving cavity 161. One end of the handle body 120 extends into the receiving cavity 161 through the opening 162 to be sleeved on the handle shaft 110, and the opening 162 provides clearance for the rotation of the handle body 120.

[0080] The control handle 100 uses the handle base 160 as the basic structure to install / set components such as the handle shaft 110 and the handle body 120. When the handle body 120 rotates relative to the handle shaft 110, it moves within the opening 162 corresponding to the handle base 160, and the opening 162 provides clearance for it. Among them, the clearance range of the opening 162 can be set according to the adjustable angle of the handle body 120.

[0081] The handle base 160 can serve as the connection hub between the control handle 100 and the equipment main body of the photography support frame. By setting specific installation structures, such as screw holes, clamping grooves, etc., the control handle 100 is firmly installed on the equipment main body to ensure that the control handle 100 will not loosen or fall off easily during operation. In addition, the handle base 160 can also be integrally formed with a partial structure of the equipment main body of the photography support frame, and this embodiment does not limit this.
