[0038] Embodiment 1:
[0039] like Figures 1 to 6 As shown, this embodiment provides a one-key unlocking softbox chuck assembly, comprising a shell 1, a plurality of rib shafts 2, an elastic reset mechanism, and a rotating ring 3; the plurality of rib shafts 2 are arranged at intervals along the circumference of the shell 1, and the rib shafts 2 are hinged to the shell 1; the rotating ring 3 is arranged in the shell 1, and can rotate circumferentially relative to the shell 1; a first locking mechanism is provided on the rib shaft 2, and a second locking mechanism corresponding to the first locking mechanism is provided on the rotating ring 3; the rib shaft 2 is rotated, the first locking mechanism is connected to the second locking mechanism, and the rib shaft 2 is locked; the rotating ring 3 is rotated, the first locking mechanism is separated from the second locking mechanism, and the rib shaft 2 is unlocked; one end of the elastic reset mechanism is connected to the rotating ring 3, and the other end is connected to the shell 1.
[0040] According to the above technical solution, the rib shaft 2 is hinged to the shell 1. When the rib shaft 2 is rotated to a vertical state with the shell 1, that is, in the storage state, the first locking mechanism is separated from the second locking mechanism; when the rib shaft 2 needs to be opened, the rib shaft 2 is unfolded one by one, and the rib shaft 2 is rotated one by one until the rib shaft 2 and the shell 1 are in a horizontal state. When the rib shaft 2 is fully unfolded, the first locking mechanism is connected to the second locking mechanism to lock the rib shaft 2. At this time, the rib shaft 2 can no longer rotate; when the rib shaft 2 needs to be stored, the rotating ring 3 is rotated to separate the first locking mechanism from the second locking mechanism, thereby unlocking the rib shaft 2. At this time, the rib shaft 2 can be rotated. For example, under the tension of the soft box umbrella cloth, the unlocked rib shaft 2 is rotated to a vertical state with the shell 1; the rotating ring 3 is released, and the rotating ring 3 is restored to its original position under the action of the elastic reset mechanism. The soft box chuck assembly provided by the utility model can simultaneously unlock multiple rib shafts 2 by only rotating the rotating ring 3 when unlocking the rib shaft 2, which is simple and convenient to operate; and the locking of the multiple rib shafts 2 does not interfere with each other, and they are securely locked after unfolding.
[0041] like Figures 2 to 5 As shown, the first locking mechanism includes a first elastic member, a first locking pin 4, and the second locking mechanism is a buckle groove 5; one end of the first elastic member is connected to the rib shaft 2, and the other end is connected to the first locking pin 4; the rib shaft 2 is rotated, and the first locking pin 4 is clamped in the buckle groove 5; the rotating ring 3 is rotated, and the first locking pin 4 is separated from the buckle groove 5. When the rib shaft 2 is in the storage state, the first locking pin 4 is always kept against the shell 1 under the action of the first elastic member. During the process of rotating the rib shaft 2, the first locking pin 4 is also always kept against the shell 1 or the rotating ring 3 until it is rotated to the fully unfolded state. The first locking pin 4 is pushed by the first elastic member to fall into the buckle groove 5, and due to the action of the first elastic member, the first locking pin 4 is always kept clamped in the buckle groove 5, so as to achieve the locking of the rib shaft 2. The rotating ring 3 is rotated, and the first locking pin 4 is separated from the buckle groove 5, so as to achieve the unlocking of the rib shaft 2.
[0042] like Figure 4 and Figure 5As shown, a first arc surface 6 abutting against the first lock pin 4 is provided on the housing 1, and a second arc surface 7 abutting against the first lock pin 4 is provided on the rotating ring 3, one end of the second arc surface 7 is connected to the first arc surface 6, and the other end is connected to the buckle groove 5; the rib shaft 2 is rotated, and the first lock pin 4 moves along the first arc surface 6 and the second arc surface 7 until it falls into the buckle groove 5. The rotating ring 3 is provided with a third arc surface 9, and one end of the rib shaft 2 is provided with a fourth arc surface 8 matching with the third arc surface 9. When the rib shaft 2 is rotated, the end of the rib shaft 2 moves along the third arc surface 9, and the third arc surface 9 abuts against the fourth arc surface 8. As shown in the figure, the rotating ring 3 is provided with a plurality of first protrusion structures at intervals in the circumferential direction, the buckle groove 5 and the second arc surface 7 are both provided on the first protrusion structure, the housing 1 is provided with a second protrusion structure, and the first arc surface 6 is provided on the second protrusion structure. When the rib shaft 2 is rotated, the first lock pin 4 moves along the first arc surface 6 and the second arc surface 7 until it falls into the buckle groove 5; because the first lock pin 4 is connected to the first elastic member, under the action of the first elastic member, the first lock pin 4 can be firmly clamped in the buckle groove 5. At the same time, when the rib shaft 2 rotates, the fourth arc surface 8 of the end face of the rib shaft 2 contacts the third arc surface 9 on the rotating ring 3 and rotates along the third arc surface 9. The provision of the first arc surface 6 and the second arc surface 7 makes the movement of the first lock pin 4 smoother; the provision of the third arc surface 9 and the fourth arc surface 8 makes the rotation of the rib shaft 2 smoother; through the above provision, the rib shaft 2 is more labor-saving when being stored, and the user's operating feel is also improved.
[0043] like Figures 4 to 6 As shown, the rib shaft 2 is hinged to the shell 1 through a rotating shaft, and the first locking pin 4 is arranged parallel to the rotating shaft of the rib shaft 2. A mounting groove is provided at one end of the rib shaft 2 where the fourth arc surface 8 is provided, and a mounting cavity connected to the mounting groove is provided inside the rib shaft 2. The first locking pin 4 is installed in the mounting groove, and one end extends out of the mounting groove; the first elastic member is installed in the mounting cavity. The first locking pin 4 is installed in the mounting groove and can move in the mounting groove, and the first elastic member is arranged vertically to the first locking pin 4; no matter whether the rib shaft 2 is in the storage state or the unfolded state, the first locking pin 4 always maintains a state of abutting against the rotating ring 3 or the shell 1 under the action of the first elastic member; when the rib shaft 2 is in the storage state, the first locking pin 4 is abutted against the first arc surface 6 on the second protruding structure under the action of the first elastic member; when the rib shaft 2 is in the unfolded state, the first locking pin 4 is in contact with the buckle groove 5 under the action of the first elastic member. When the rib shaft 2 needs to be unlocked, the rotating ring 3 is rotated and the first locking pin 4 is separated from the buckle groove 5. Since the buckle groove 5 is arranged on the first protruding structure, when the rotating ring 3 is rotated, the first locking pin 4 will slide from the first protruding structure to the third arc surface 9 of the rotating ring 3. At this time, the rib shaft 2 has been unlocked. The rib shaft 2 is rotated to the storage state. During the rotation, the first locking pin 4 moves along the third arc surface 9 to the first arc surface 6 of the second protruding mechanism to complete the storage. At this time, the rotating ring 3 returns to its original position under the action of the elastic reset mechanism.
[0044] like Figure 2 and Figure 3 As shown, the elastic restoring mechanism includes a second elastic member 10, and a plurality of second elastic members 10 are arranged at intervals along the circumference of the rotating ring 3, one end of the second elastic member 10 is connected to the rotating ring 3, and the other end is connected to the housing 1. The second elastic member 10 is arranged along the circumference of the rotating ring 3, and the elastic restoring force of the second elastic member 10 causes the rotating ring 3 to rotate and return to its original position.
[0045] like Figure 1 As shown, in this embodiment, the shell 1 is an annular structure, and the shell 1 includes an upper shell and a lower shell; the upper shell and the lower shell are detachably connected; an annular installation space is formed between the upper shell and the lower shell, and the rotating ring 3 is located in the installation space; the rotating ring 3 is coaxially arranged with the shell 1. The inner circumferential wall of the rotating ring 3 is against the inner circumferential wall of the shell 1, which can ensure the stable rotation of the rotating ring 3 and will not shake during rotation. In order to reduce the friction between the rotating ring 3 and the shell 1, a plurality of limiting protrusions are provided on the inner circumferential wall of the shell 1, and the rotating ring 3 is sleeved on the limiting protrusions, which can reduce the contact area between the rotating ring 3 and the shell 1, thereby reducing the friction resistance.
[0046] In addition, a lever 18 is provided on the rotating ring 3, an opening is provided on the housing 1, and a support rod 19 is provided on the housing 1. The support rod 19 is provided beside the opening, and the lever 18 extends out of the housing 1 from the opening. When the operator rotates the rotating ring 3, the index finger is supported on the support rod 19, and the thumb is supported on the lever 18, and the thumb is used to push the lever 18 to realize the rotation of the rotating ring 3; the lever 18 and the support rod 19 are provided to facilitate the operator to rotate the lever 18; by limiting the length of the bayonet, the rotation angle of the rotating ring 3 can be limited, so as to avoid the operator from using too much force to make the rotating ring 3 rotate too much, thereby affecting the normal unlocking of the umbrella rib shaft 2.
[0047] Example 2
[0048] like Figures 7 to 11 As shown, this embodiment provides a one-key unlocking softbox chuck assembly, comprising a shell 1, a plurality of rib shafts 2, an elastic reset mechanism, and a rotating ring 3; the plurality of rib shafts 2 are arranged at intervals along the circumference of the shell 1, and the rib shafts 2 are hinged to the shell 1; the rotating ring 3 is arranged in the shell 1, and can rotate circumferentially relative to the shell 1; a first locking mechanism is provided on the rib shaft 2, and a second locking mechanism corresponding to the first locking mechanism is provided on the rotating ring 3; the rib shaft 2 is rotated, the first locking mechanism is connected to the second locking mechanism, and the rib shaft 2 is locked; the rotating ring 3 is rotated, the first locking mechanism is separated from the second locking mechanism, and the rib shaft 2 is unlocked; one end of the elastic reset mechanism is connected to the rotating ring 3, and the other end is connected to the shell 1.
[0049] According to the above technical solution, the rib shaft 2 is hinged to the shell 1. When the rib shaft 2 is rotated to a state perpendicular to the shell 1, that is, in a storage state, the first locking mechanism is separated from the second locking mechanism; when it is necessary to open the rib shaft 2, the rib shafts 2 are unfolded one by one, and the rib shafts 2 are rotated one by one until the rib shafts 2 and the shell 1 are in a horizontal state. When the rib shaft 2 is fully unfolded, the first locking mechanism is connected to the second locking mechanism to lock the rib shaft 2. At this time, the rib shaft 2 can no longer rotate; when it is necessary to store the rib shaft 2, the rotating ring 3 is rotated to separate the first locking mechanism from the second locking mechanism, thereby unlocking the rib shaft 2. At this time, the rib shaft 2 can be rotated to make the rib shaft 2 rotate to a state perpendicular to the shell 1, and the storage is completed; the rotating ring 3 is released, and the rotating ring 3 is restored to its original position under the action of the elastic reset mechanism. The soft box chuck assembly provided by the utility model can simultaneously unlock multiple rib shafts 2 by only rotating the rotating ring 3 when unlocking the rib shaft 2, which is simple and convenient to operate; and the locking of the multiple rib shafts 2 does not interfere with each other, and they are securely locked after unfolding.
[0050] like Figures 8 to 11 As shown, the first locking mechanism is a socket 11; the second locking mechanism includes a second locking pin 12 and a third elastic member 13; one end of the third elastic member 13 is connected to one end of the second locking pin 12, and the other end is connected to the rotating ring 3 through a connecting member 14; when the rib shaft 2 is in the storage state, the other end of the second locking pin 12 abuts against the rib shaft 2; when the rib shaft 2 is in the open state, the second locking pin 12 is inserted into the socket 11. The socket 11 is provided on the side wall of the rib shaft 2; when the rib shaft 2 is in the storage state, the second locking pin 12 always abuts against the side wall of the rib shaft 2 under the action of the third elastic member 13; when the rib shaft 2 is rotated to the unfolded state, the second locking pin 12 still abuts against the side wall of the rib shaft 2, until the rib shaft 2 is fully opened, the second locking pin 12 is pushed by the third elastic member 13 to be inserted into the socket 11, thereby locking the rib shaft 2. When the rib shaft 2 needs to be stored again, the rotating ring 3 is rotated, and the rotating ring 3 drives the third elastic member 13 and the second locking pin 12 to move until the second locking pin 12 is separated from the rib shaft 2, thereby unlocking the rib shaft 2.
[0051] In this embodiment, the socket 11 is configured as a cylindrical socket 11, and the second locking pin 12 is a conical structure. This configuration can reduce the contact area between the second locking pin 12 and the socket 11, reduce friction, and facilitate the insertion and withdrawal of the second locking pin 12.
[0052] like Figure 8 and Fig. 9As shown, the elastic reset mechanism includes a fourth elastic member 15, one end of the fourth elastic member 15 is connected to the connecting member 14, and the other end is connected to the housing 1. The second locking mechanism also includes a connecting block 16 fixedly mounted on the rotating ring 3, a through hole 17 is provided on the connecting block 16, and the second lock pin 12 can be slidably penetrated in the through hole 17. The connecting member 14 can be a connecting plate, which is vertically arranged and mounted on the connecting block 16; a connecting column is arranged on the housing 1, one end of the second elastic member 10 is connected to the connecting member 14, and the other end is connected to the connecting column. The connecting block 16 is provided with a through hole 17, and the second lock pin 12 is penetrated in the through hole 17, one end of the third elastic member 13 is connected to the connecting member 14, and the other end is connected to the second lock pin 12, and the second lock pin 12 can slide in the through hole 17 through the elastic force of the third elastic member 13.
[0053] In this embodiment, the elastic restoring force of the fourth elastic member 15 is greater than the elastic restoring force of the third elastic member 13. This arrangement facilitates the rotating ring 3 to smoothly return to its original position.
[0054] like Fig.10 and Fig.11 As shown, the rotating ring 3 is provided with a third curved surface 9, and the rib shaft 2 is provided with a fourth curved surface 8 matched with the third curved surface 9. When the rib shaft 2 is rotated, the rib shaft 2 rotates along the third curved surface 9 through the fourth curved surface 8, and the third curved surface 9 abuts against the fourth curved surface 8. By setting the third curved surface 9 and the fourth curved surface 8, the rib shaft 2 has less obstruction during rotation, and the rotation is smoother, which improves the user's hand feeling.
