DETAILED DESCRIPTION

[0040] In order to enable the personnel in the technical field to better understand the present application scheme, the technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by the personnel in the field without creative labor should belong to the protection scope of the present application.

[0041] As shown in Figures 1-9 , a folding soft light box chuck comprises a first base 1, a second base 2 rotatably connected to the first base 1, and a locking mechanism 4. The first base 1 is in an open ring structure with a notch portion 3, and a plurality of first support pieces can be arranged on the outer periphery of the first base 1. The central angle of the first base 1 is greater than 180°, in other words, the central angle of the notch portion 3 is less than 180°.

[0042] The first base 1 and the second base 2 have at least a storage state and an unfolded state. In the unfolded state, the first base 1 and the second base 2 are located in the same plane, and the second base 2 makes up the notch portion 3 to form a complete circular ring, as shown in Figure 1 , Figure 2 , the inner and outer circles of the circular ring are smooth and complete circles, in other words, the width of the circular ring is substantially equal at all positions.

[0043] As shown in Figure 9As shown, in the storage state, the first base 1 and the second base 2 are stacked one on top of the other, at this time, the first support on the first base 1 and the second support on the second base 2 are located on the same side, so that the soft light box can be folded and stored as a whole to a flat shape, and the space occupied during storage is small.

[0044] Specifically, as shown in the drawings, Figure 5 The first base 1 includes a first base body 11, and a first elongated arm 12 extending from the end of the first base body 11 along the circumference, and the radial width of the first elongated arm 12 is smaller than the radial width of the first base body 11. In this embodiment, the two ends of the first base body 11 are both extended along the circumference to form the first elongated arm 12, and the lengths of the two first elongated arms 12 are substantially equal. The central angle of the first base body 11 is 180°, that is, the first base body 11 is a semicircular ring, of course, in other embodiments, it can not be a semicircular ring, and the specific limitation is not limited.

[0045] Therefore, the gap part 3 includes an inner gap 31 and an outer gap 32, the inner gap 31 is formed between the ends of the two adjacent first elongated arms 12, and the outer gap 32 is formed between the two ends of the first base body 11, that is, the outer gap 32 is formed between the regions of the two ends of the first base body 11 without the first elongated arm 12, and the outer gap 32 is located outside the inner gap 31.

[0046] As shown in the drawings, Figure 6 The second base 2 includes a second base body 21, and a protruding part 22 protruding from the inner circle of the second base body 21, the protruding part 22 fills the inner gap 31 to form a complete circular ring, and the second base body 21 fills the outer gap 32 to form a complete circular ring. In other words, the radial width and the circumferential length of the protruding part 22 are substantially equal to those of the inner gap 31, and the radial width and the circumferential length of the second base body 21 are substantially equal to those of the outer gap 32. In this embodiment, the central angle of the second base body 21 is 180°, that is, the second base body 21 is a semicircular ring, of course, in other embodiments, it can not be a semicircular ring, and the specific limitation is not limited.

[0047] The locking mechanism 4 is used to lock or unlock the first base 1 and the second base 2, when the first base 1 and the second base 2 are in the unfolded state, the locking mechanism 4 locks the first base 1 and the second base 2, so that they are stably kept in the unfolded state. When the locking mechanism 4 unlocks the first base 1 and the second base 2, it can be switched from the unfolded state to the storage state.

[0048] As shown in the drawings, Figure 4 , Figure 10 , Figure 11The locking mechanism 4 is shown to lock the first base 1 and the second base 2 in the radial direction. The locking mechanism 4 includes an unlocking member 41, a locking member 42 matched with the unlocking member 41, a reset member 43 abutting against the locking member 42, and a locking groove 44. The locking member 42 and the locking groove 44 are arranged on the first base 1 or the second base 2 respectively. When the unlocking member 41 is driven to move by an external force, the locking member 42 is driven to move, so that part of the locking member 42 enters or leaves the locking groove 44.

[0049] Specifically, in the embodiment, the locking member 42 is rotatably connected to the second base 2, and is arranged at a position corresponding to the protruding portion 22. The locking member 42 has two first locking portions 421, and each first locking portion 421 has an inclined guide surface 422. The locking groove 44 is arranged on the outer side of the first base 1, and is arranged on the outer side of the first elongated arm 12 near the notch portion 3. Correspondingly, the locking groove 44 also has two, and the positions correspond to the locking member 42.

[0050] The unlocking member 41 has one, and is matched with the two locking members 42 respectively. When the unlocking member 41 is driven to move in the radial direction of the soft light box chuck by an external force, the two locking members 42 are driven to rotate synchronously, so that the first locking portion 421 can leave the locking groove 44 to realize the unlocking of the first base 1 and the second base 2. The first base 1 and the second base 2 can rotate freely to switch from the unfolded state to the storage state. At this time, the external force applied to the unlocking member 41 is stopped, and the locking member 42 is automatically reset under the elastic force of the reset member 43. In the embodiment, the reset member 43 is a torsion spring, one open end of which abuts against the first locking portion 421, and the other open end of which abuts against the second base 2.

[0051] When the first base 1 and the second base 2 switch from the storage state to the unfolded state, the inclined guide surface 422 of the first locking portion 421 abuts against the area of the surface of the first elongated arm 12 corresponding to the locking groove 44, and overcomes the rotation of the reset member 43 until the first locking portion 421 enters the locking groove 44 to realize the locking of the first base 1 and the second base 2. In order to facilitate the sliding of the first locking portion 421 into the locking groove 44, the area of the surface of the first elongated arm 12 corresponding to the locking groove 44 can be arranged as a circular arc structure. In order to increase the contact area of the first locking portion 421 and the locking groove 44, the inner bottom surface of the locking groove 44 protrudes from the outer side of the first elongated arm 12.

[0052] Since the above structure is that the first locking portion 421 is inserted into the locking groove 44 in the radial direction, it is defined that the locking mechanism 4 locks the first base 1 and the second base 2 in the radial direction. Of course, in other embodiments, the locking mechanism 4 can lock the first base 1 and the second base 2 in the radial direction and the circumferential direction.

[0053] As Figures 12-19As shown, unlike the structure and setting position of the locking groove 44, the locking groove 44 is set at the end of the first base 1, specifically, the locking groove 44 is set at the end of the first elongated arm 12, and it extends the end surface and the outer lateral surface of the first elongated arm 12. As shown, Figure 14 As shown, the side of the locking groove 44 has an inclined abutting surface 441 which extends from the outer periphery of the first elongated arm 12 to the inner ring in the direction deviating from the center; the top of the locking groove 44 has an inclined inner top surface 442 which extends in the thickness direction of the first elongated arm 12. As shown, Figure 15 As shown, the locking member 42 which is rotationally connected to the second base 2 has a second locking portion 423 of another structure, the second locking portion 423 is formed with an inclined surface 424 which can abut against the abutting surface 441, and an inclined surface 425 which can abut against the inner top surface 442 of the locking groove.

[0054] As shown, Figure 16 , Figure 17 As shown, during the process of switching the first base 1 and the second base 2 from the unlocked state to the locked state, the inclined surface 425 slides against the inner top surface 442 of the locking groove until the inclined surface 424 abuts against the abutting surface 441, at this time, the second locking portion 423 and the locking groove 44 not only have radial locking force, but also have circumferential locking force, thus defining the locking mechanism 4 which locks the first base 1 and the second base 2 in the radial and circumferential directions.

[0055] As shown, Figure 18 , Figure 19 As shown, once the external force is applied to press the unlocking member 41 inward, and the two locking members 42 are driven to rotate until the second locking portion 423 is separated from the inner bottom surface of the locking groove 44, the first base 1 and the second base 2 are unlocked to be freely rotatable.

[0056] In order to facilitate the unfolding and storage operation, the second base 2 is provided with a handle portion 5 which is arranged corresponding to the protruding portion 22, specifically, the protruding portion 22 is located at the inner ring of the second base body 21, and the handle portion 5 is located at the outer ring of the second base body 21 corresponding to the position of the protruding portion 22. And the handle portion 5 extends obliquely, which extends outward from the center of the soft light box chuck and obliquely towards the direction of the soft light cloth, as shown. Figure 3 As shown, in order to improve the hand feeling of the operator, the handle portion 5 has an arc surface.

[0057] Of course, the unlocking piece 41 and the locking piece 42 can also be fixedly connected and matched, the locking piece 42 is in a U shape, has two first locking portions 421 which are arranged correspondingly to the two locking grooves 44 of the first base 1, one end of the reset piece 43 is abutted against the first locking portion 421, one end is abutted against the second base 2, and the number of the reset piece 43 is two. The reset piece 43 is stretched to drive the first locking portion 421 to enter the locking groove 44, once an external force is applied to pull the unlocking piece 41 outward, the locking piece 42 compresses the reset piece 43 and is separated from the locking groove 44, and the unlocking of the first base 1 and the second base 2 is realized. In order to facilitate the first locking portion 421 to enter the locking groove 44, the end of the first locking portion 421 which is away from the unlocking piece 41 also has an inclined guide surface.

[0058] The above specific embodiments are used to explain and illustrate the present application, rather than limit the present application, and any modification and change made to the present application within the spirit and protection scope of the claims of the present application all fall into the protection scope of the present application.
