The present invention proposes a chuck assembly 100 of a soft light box, referring to fig. 1 to 5, the chuck assembly 100 of the soft light box comprising:

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

a plurality of locking members 120 movably disposed on the chuck 110, each locking member 120 being configured to hold an umbrella rib 200;

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

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

The chuck assembly 100 of the present embodiment is provided as a component of a soft light case for mounting ribs 200 of the soft light case. 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 mounted to the chuck 110. Each rib 200 is hinged to the chuck 110 and is movable relative to the chuck 110. Wherein, one end of each rib 200 hinged to the chuck 110 (i.e., the hinged end) is in an unfolded state when moved to be substantially perpendicular to the central axis of the chuck 110, and in a stored state when moved to be parallel to the central axis of the chuck 110.

The locking members 120 are provided in plurality and movably disposed on the chuck 110, and each locking member 120 is used for pressing and holding an umbrella rib 200. A pressing position for pressing the rib 200 is formed on the movement path of the locking piece 120, and when the locking piece 120 moves to the pressing position, the locking piece 120 can press the unfolded rib 200, and the rib 200 is in an immovable state; when the locking member 120 moves away from the holding position, the locking member 120 releases the rib 200 accordingly, and the rib 200 is in a movable state. When the locking member 120 presses the rib 200, the locking member may be pressed against the hinged end of the rib 200. Alternatively, the movement form of the locking member 120 may be translational (i.e., parallel movement), rotational, etc., as the case may be. And when the locking member 120 translates, the translation direction may be along the radial direction or the axial direction of the chuck 110, according to the actual situation. In the present 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 ribs 200 are unfolded, the ribs 200 are held by the locking members 120 in a one-to-one correspondence manner so as to maintain the unfolded state; when the locking members 120 move to release the ribs 200, the ribs 200 can move relatively, so that the folded state is switched from the unfolded state to the storage state. Alternatively, when the locking member 120 releases the rib 200, the locking member 120 does not apply a pressing force to the rib 200, and the rib 200 can move under the action of its own weight, so that the folded state is switched to the storage state, and the folded state is automatically folded without manual operation.

The rotating ring 130 is rotatably disposed on the chuck 110, and can move each locking member 120 through its own rotation (clockwise rotation or counterclockwise rotation). Specifically, when the rotation ring 130 rotates to drive each locking element 120 to move beyond a preset distance, that is, each locking element 120 leaves the holding position to release the rib 200, so that the rib 200 can move relative to the chuck 110. Connection structures (not shown) may be provided between the rotation ring 130 and each of the locking members 120 to transmit power to each of the locking members 120 through the connection structures when the rotation ring 130 rotates, and each of the locking members 120 moves accordingly.

Specifically, taking a movement form of the locking member 120 translating along the radial direction of the chuck 110 as an example, each of the connection structures may include a rotating shaft rotatably disposed on the chuck 110 and parallel to the central axis of the chuck 110, and a double gear spacer sleeved on the rotating shaft, wherein the inner side wall or the outer side wall of the rotating ring 130 is formed with a tooth pattern to engage with one of the double gears, and the locking member 120 is also correspondingly formed with a tooth pattern or is provided with a rack to engage with the other of the double gears. With this configuration, the rotation ring 130 rotates, and the transmission locking member 120 moves through the structure of the rotation shaft and the double gears. Of course, this is merely exemplary and is not limiting.

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

According to the chuck assembly 100 of the soft light box of the present embodiment, each locking member 120 can be correspondingly moved by operating the rotating ring 130 to rotate, and when the rotating ring 130 rotates by a certain angle, each locking member 120 moves beyond a preset distance, so that the corresponding pressed rib 200 is released, and each rib 200 can move relative to the chuck 110, thereby realizing folding and storage.

The chuck assembly 100 of the soft light box can unlock all the umbrella ribs 200 by only rotating the rotating ring 130, and compared with the independent unlocking mode of each umbrella rib 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:

and a plurality of first restoring members 140, wherein each first restoring member 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 restore.

In this embodiment, in the locked state of the 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 rib 200. In the unlocking process, when the rotating ring 130 rotates to drive each locking piece 120 to move from the initial position towards the central axis direction of the chuck 110 by more than a preset distance, each locking piece 120 releases the umbrella rib 200; when the unlocking is completed, the first restoring member 140 applies an elastic force to the locking member 120 toward 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 practical situations.

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

the chuck base 111 is provided with a plurality of accommodating grooves 111a arranged around the central axis thereof, each locking piece 120 is slidably arranged in one accommodating groove 111a and can slide towards or away from the central axis of the chuck base 111, and the first resetting piece 140 is elastically compressed between the locking piece 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 accommodating grooves 111a on the chuck base 111 are disposed around a central axis thereof, and the plurality of accommodating grooves 111a are sequentially disposed at intervals along a periphery of the chuck base 111 and correspondingly mount a plurality of locking members 120. The receiving groove 111a extends in a radial direction of the chuck 110, and the locking member 120 is slidably disposed in the receiving groove 111a to be slidable along the receiving groove 111a toward or away from a central axis of the chuck 110. When the chuck 110 is unlocked, the rotary ring 130 rotates to drive the locking piece 120 to move along the direction of the central axis of the accommodating groove 111 a; after unlocking is completed, under the action of the elastic force applied to the locking member 120 by the first restoring member 140, the locking member 120 moves in the direction of the receiving groove 111a away from the central axis of the chuck 110 to restore.

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

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

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

Based on the structural design between the rotating ring 130 and the locking member 120 in the present embodiment, along the first direction in the circumferential direction of the rotating ring 130, the distance from each abutment surface 130a to the central axis of the chuck base 111 increases progressively, i.e. the abutment surface 130a has a valley and a peak. When the rib 200 is in the locked state, each of the propping members 121 is propped against the propping surface 130a (at this time, the propping members 121 are located at the sloping valley of the propping surface 130 a) under the elastic force of the first reset member 140. The unlocking process of the umbrella rib 200 is as follows: the rotating ring 130 is rotated, each abutting piece 121 is pressed by the abutting surface 130a of the rotating ring 130, so that each abutting piece 121 moves along the abutting surface 130a abutted by the abutting piece (moves from the valley of the abutting surface 130a to the peak), and under the guidance of the accommodating groove 111a, each abutting piece 121 drives the locking piece 120 to move towards the central axis direction of the chuck 110, and when the locking piece 120 moves beyond a preset distance (the abutting piece 121 moves to the peak of the abutting surface 130 a), the umbrella rib 200 is automatically released, so that unlocking of the umbrella rib 200 is realized. After the unlocking is completed, the locking member 120 moves away from the central axis of the chuck 110 by the elastic force of the first reset member 140, so as to drive the abutting member 121 to move along the abutting surface 130a abutted by the locking member to reset (move from the slope peak to the slope valley of the abutting surface 130 a). Alternatively, the first direction involved may be a clockwise or counter-clockwise direction. Preferably, the abutment surface 130a is a 1/4 circular arc surface.

In some embodiments, referring to fig. 3 and 7, the abutment surface 130a is a cambered surface or an inclined surface;
