The present invention provides a chuck assembly 100 of a soft box, and referring to fig. 1 to 5, the chuck assembly 100 of the soft box includes:

a chuck 110 for mounting a plurality of ribs 200 hinged thereto;

a plurality of locking members 120 movably provided on the chuck 110, each locking member 120 for pressing and holding a rib 200;

a rotating ring 130 rotatably provided on the chuck 110 for driving each locking member 120 to move by rotation;

when the rotating ring 130 rotates to drive each locking member 120 to move beyond a preset distance, each locking member 120 releases the umbrella rib 200, so that the umbrella rib 200 can move relative to the chuck 110.

The chuck assembly 100 of the present embodiment is used as a component structure of the soft box for mounting the umbrella ribs 200 of the soft box. Specifically, the chuck assembly 100 includes a chuck 110, a locking member 120, and a rotating ring 130, wherein the chuck 110 may have a disk shape, and a plurality of ribs 200 may be sequentially spaced along an edge of the chuck 110 when being mounted to the chuck 110. Each rib 200 is hingedly connected to chuck 110 and is movable relative to chuck 110. Wherein, one end (i.e., a hinged end) of each rib 200 hinged to the chuck 110 is in an unfolded state when moved to be substantially perpendicular to the central axis of the chuck 110, and is in a stored state when moved to be parallel to the central axis of the chuck 110.

Wherein, the locking member 120 has a plurality and is movably provided on the chuck 110, and each locking member 120 is used for pressing and holding a rib 200. A pressing position for pressing the umbrella rib 200 is formed on the moving path of the locking piece 120, when the locking piece 120 moves to the pressing position, the locking piece 120 can press the unfolded umbrella rib 200, and the umbrella rib 200 is in a non-movable state; when the locking member 120 moves out of the pressing position, the locking member 120 correspondingly releases the umbrella rib 200, and the umbrella rib 200 is in a movable state. When the locking member 120 presses the rib 200, it may be pressed against the hinge end of the rib 200. Alternatively, the movement of the locking member 120 may be translational (i.e., parallel), rotational, etc., as the case may be. And when the locking member 120 translates, the direction of translation may be in a radial or axial direction of the chuck 110, as the case may be. In this embodiment, the external configuration of the locking member 120 is not limited, and for example, the locking member 120 may have a block shape as shown in fig. 2.

When the umbrella ribs 200 are unfolded, the plurality of umbrella ribs 200 are pressed and held one by the plurality of locking pieces 120 to maintain the unfolded state; when the plurality of locking members 120 are moved to release the plurality of ribs 200, the plurality of ribs 200 can be moved relatively, and the folding state is switched from the unfolded state to the storage state. Alternatively, when the locking member 120 releases the umbrella rib 200, the locking member 120 does not apply a pressing force to the umbrella rib 200, and the umbrella rib 200 can move under the action of its own gravity, and is switched from the unfolded state to the storage state, and is automatically folded without manual operation.

The rotating ring 130 is rotatably disposed on the chuck 110, and can be rotated (clockwise or counterclockwise) to move each locking member 120. Specifically, when the rotating ring 130 rotates to move each locking member 120 beyond a predetermined distance, each locking member 120 leaves the pressing position to release the rib 200, so that the rib 200 can move relative to the chuck 110. A connection structure (not shown) may be provided between the rotating ring 130 and each of the locking members 120, so that when the rotating ring 130 rotates, each of the locking members 120 moves accordingly by transmitting power to each of the locking members 120 through the connection structure.

Specifically, taking the form of the translational movement of the locking member 120 along the radial direction of the chuck 110 as an example, each of the connecting structures may include a rotating shaft and a double gear, the rotating shaft is rotatably disposed on the chuck 110 and is parallel to the central axis of the chuck 110, the double gear is sleeved on the rotating shaft at intervals, the inner side wall or the outer side wall of the rotating ring 130 is formed with a gear rack to mesh with one of the double gear, and the locking member 120 is also formed with a gear rack or is mounted with a gear rack to mesh with the other of the double gear. In this configuration, the rotating ring 130 rotates, and the driving locking member 120 moves through the structure of the rotating shaft and the double gears. Of course, this is merely exemplary and not limiting.

In addition, as an alternative, the rotation of the rotating ring 130 may be performed manually or driven by a driving mechanism (such as a motor or other driving power source), and the embodiment is not limited.

Based on the chuck assembly 100 of the soft light box of this embodiment, each locking piece 120 can move correspondingly by operating the rotation ring 130 to rotate, and when the rotation ring 130 rotates a certain angle, each locking piece 120 moves beyond a preset distance, so as to loosen the corresponding umbrella ribs 200, and each umbrella rib 200 can move relative to the chuck 110, thereby realizing folding and storage.

The chuck assembly 100 of the soft light box can realize one-key unlocking of all the umbrella ribs 200 only by rotating the rotating ring 130, and compared with the mode of independently unlocking all the umbrella ribs 200 of the soft light box at present, the chuck assembly is simple to operate and convenient to use, and is beneficial to improving the use experience of users.

In some embodiments, referring to fig. 3 and 4, the chuck assembly 100 of the soft box further comprises:

each of the first resetting members 140 applies an elastic force to the locking member 120 in a direction away from the central axis of the chuck base, so as to drive the locking member 120 to move and reset.

In this embodiment, in the locked state of the umbrella rib 200, the first restoring member 140 keeps applying an elastic force to the locking member 120 in a direction away from the central axis of the chuck 110, so that the locking member 120 is stably pressed against the umbrella rib 200. In the unlocking process, when the rotating ring 130 rotates to drive each locking piece 120 to move from the initial position to the central axis direction of the chuck 110 for more than a preset distance, each locking piece 120 loosens the umbrella rib 200; when the unlocking is completed, the first restoring member 140 applies an elastic force to the locking member 120 in a direction away from the central axis of the chuck 110, so that the locking member 120 moves to an initial position away from the central axis of the chuck 110. Optionally, the first restoring member 140 is a spring or a tension spring, which is selected according to actual situations.

In some embodiments, referring to fig. 2, 3, 5 and 6, chuck 100 includes:

the chuck base 111 is provided with a plurality of accommodating grooves 111a arranged around the central axis thereof, each locking member 120 is slidably arranged in one of the accommodating grooves 111a and can slide towards or away from the central axis of the chuck base 111, and the first resetting member 140 is elastically compressed between the locking member 120 and the groove side wall of the accommodating groove 111a.

In this embodiment, the chuck 110 includes a chuck base 111, a plurality of receiving grooves 111a on the chuck base 111 are disposed around a central axis thereof, and the plurality of receiving grooves 111a are sequentially disposed at intervals along a circumference of the chuck base 111 and correspondingly mounted with a plurality of locking members 120. The receiving groove 111a extends along a radial direction of the chuck 110, and the locking member 120 is slidably disposed in the receiving groove 111a so as to be slidable along the receiving groove 111a toward or away from a central axis of the chuck 110. When unlocking, the rotating ring 130 rotates to drive the locking piece 120 to move along the accommodating groove 111a towards the central axis direction of the chuck 110; after the unlocking is completed, under the elastic force applied to the locking member 120 by the first resetting member 140, the locking member 120 moves along the receiving groove 111a in the direction away from the central axis of the chuck 110 to be reset.

In some embodiments, referring to fig. 3 and 7, the rotating ring 130 has a plurality of abutting surfaces 130a formed thereon;

one end of each locking member 120 facing the central axis of the chuck base 111 is provided with a supporting member 121, and each supporting member 121 supports against a supporting surface 130a;

in the first direction along the circumferential direction of the rotating ring 130, the distance from each abutting surface 130a to the central axis of the chuck base 111 increases.

Based on the structural design between the rotating ring 130 and the locking member 120 of the present embodiment, the distance from each abutting surface 130a to the central axis of the chuck base 111 increases along the first direction in the circumferential direction of the rotating ring 130, i.e., the abutting surfaces 130a have a valley and a peak. When the umbrella rib 200 is in the locked state, under the elastic force of the first restoring member 140, each of the abutting members 121 abuts against the abutting surface 130a (at this time, the abutting member 121 is located at the valley of the abutting surface 130 a). The unlocking process of the umbrella ribs 200 is as follows: when the rotating ring 130 is rotated, the abutting surface 130a of the rotating ring 130 presses each abutting member 121, so that each abutting member 121 moves along the abutting surface 130a that it abuts (moves from the valley toward the peak of the abutting surface 130 a), and under the guidance of the receiving groove 111a, each abutting member 121 drives the locking member 120 to move toward the central axis direction of the chuck 110, and when the locking member 120 moves beyond the preset distance (the abutting member 121 moves to the peak of the abutting surface 130 a), the umbrella rib 200 is automatically released, thereby unlocking the umbrella rib 200. After the unlocking is completed, the locking member 120 moves away from the central axis of the chuck 110 under the action of the elastic force of the first restoring member 140, and further drives the abutting member 121 to move and restore along the abutting surface 130a abutted by the abutting member (the slope peak of the abutting surface 130a moves towards the slope valley). Alternatively, the first direction of reference may be clockwise or counterclockwise. Preferably, the abutting surface 130a is a 1/4 arc surface.
