Detailed Description

In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 and 2, a chuck mechanism for a soft light box includes a hollow circular ring-shaped positioning member 1, a cover 2 which is in a hollow circular ring shape and is vertically assembled with the positioning member 1, a plurality of sockets 3 uniformly arranged along the circumference of the positioning member 1, and a locking mechanism 4 for locking or unlocking the sockets 3.

As shown in fig. 3 and 4, the positioning member 1 has a certain thickness, the cover 2 is plate-shaped, the cover 2 and the positioning member 1 are vertically combined to form a cavity 6, and a limiting and pressing portion 11, a supporting portion 12 and a movable passage 5 are disposed in the cavity 6. More specifically, a limiting and pressing portion 11 and a supporting portion 12 for mounting the socket 3 are formed on the side of the positioning member 1 facing the cover 2, and the movable channel 5 includes not only the portion located in the cavity 6, but also the movable channel 5 can extend out of the cavity 6. In this embodiment, the portion of the movable passage 5 extends along the radial direction of the positioning member 1, the supporting portion 12 is located at two sides of the movable passage 5, and the movable passage 5 further includes a space located below the positioning member 1, so as to ensure that the socket 3 can be rotated up and down to be unfolded or folded.

The part of the socket 3 can be clamped between the limiting and pressing part 11 and the supporting part 12, so that the socket 3 is pressed and held up and down. In other words, the socket 3 is mainly fixed by the limiting pressing part 11 and the supporting part 12 on the positioning member 1, rather than the cover 2 and the positioning member 1 being vertically combined, and even after a long time use, the cover 2 and the positioning member 1 are not vertically separated.

The socket 3 has a pivot 31 at the end, i.e. the socket 3 is T-shaped. The spacing clip 11 comprises a clip lug 111 located outside the support 12, the clip lug 111 having at least two directional openings 112, where the two directional openings 112 ensure the radial translation of the rotary fulcrum 31 into the space between the spacing clip 11 and the support 12. In order to ensure that the rotation support shaft 31 is tightly fitted between the stopper pressing portion 11 and the support portion 12, the vertical distance between the stopper pressing portion 11 and the support portion 12 is substantially equal to the outer diameter of the rotation support shaft 31.

In order to prevent the rotation fulcrum 31 from being easily released after being caught between the limit pressing part 11 and the supporting part 12, a release preventing protrusion 14 is provided on the limit pressing part 11, as shown in fig. 8 and 9, that is, a downward protrusion is formed on a side surface of the pressing protrusion 111 facing the supporting part 12, which is used for preventing the rotation fulcrum 31 from being released from the limit pressing part 11 in a radial direction, where the radial direction refers to a radial direction of the positioning member 1.

The parts of the limit pressing part 11 and the supporting part 12 are overlapped, and the overlapping here means that two pressing projections 111 are positioned on both sides of the supporting part 12 in the length direction of the supporting part 12, not on the extension line of the length direction of the supporting part 12. However, the two parts are not completely overlapped, so that a notch 15 is formed at the non-overlapped part of the support part 12 and the limit pressing part 11, when the socket 3 passes through the moving channel 5 from top to bottom, the rotating fulcrum 31 can extend into the notch 15, and after the rotating fulcrum 31 is abutted against the support part 12, the rotating fulcrum 31 can be translated into the space between the limit pressing part 11 and the support part 12 in the radial direction. In order to prevent the rotation shaft 31 from being withdrawn in a translational manner, as shown in fig. 7, a filling protrusion 21 capable of being inserted into the notch 15 is disposed on one side of the cover body 2 facing the positioning member 1, that is, as shown in fig. 5 and 6, after the cover body 2 and the positioning member 1 are assembled, the socket 3 is stably limited, the rotation shaft 31 cannot be moved away from the limiting and pressing portion 11 in a translational manner, and cannot shake, and the end of the socket 3 is completely wrapped.

In order to increase the moment, the limiting and pressing part 11 is arranged close to the inner ring of the positioning piece 1. An arched pressing section 13 is formed on the outer edge of the positioning piece 1 and above the movable channel 5, and when the socket 3 is unfolded, the outer wall of the socket 3 is abutted against the arched pressing section 13.

As shown in fig. 10-12, when the socket 3 and the positioning member 1 are assembled, the lower end of the socket 3 passes through the movable passage 5 from top to bottom, the rotating fulcrum 31 enters from the notch portion 15 and then is erected on the supporting portion 12, then an external force is applied to translate the socket 3 along the supporting portion 12 to enter below the limiting and pressing portion 11, the anti-falling protrusion 14 prevents the rotating fulcrum 31 from separating from the limiting and pressing portion 11, and finally, the notch portion 15 is filled by the filling protrusion 21 on the cover 2 through the assembly connection of the cover 2 and the positioning member 1, so that the socket 3 is wrapped, the socket 3 is ensured not to be displaced, and the stability of the unfolding and folding activities of the socket 3 is ensured.

As shown in fig. 13-15, the locking mechanism 4 at least includes a rotating shaft 41, a torsion spring 42 connected to the rotating shaft 41, an operating member 43, and a locking surface 431 disposed on the operating member 43, a recess 16 for accommodating the rotating shaft 41 is formed on the positioning member 1, a side surface of the recess 16 facing the socket 3 is opened, and a portion of the operating member 43, especially the locking surface 431, passes through the side surface opening of the recess 16 and abuts against an outer wall of the socket 3.

Because the arched pressing section 13 applies downward pressure to the socket 3, the locking surface 431 of the operating piece 43 is abutted against the outer wall of the socket 3, the problem that the operating piece 43 is easy to fall off is solved, and the assembling structure is stable and effective.

The positioning piece 1 and the cover body 2 are made of non-metal materials, the manufacturing cost is low, the limiting pressing portion 11 is located on the positioning piece 1, positioning of the socket 3 is achieved without the cover of the cover body 2, the separation phenomenon cannot occur between the cover body 2 and the positioning piece 1 after long-time use, and the service life is prolonged.

As shown in fig. 16, if it is defined that the positioning member 1 has a first outer diameter ring 101, a second outer diameter ring 102 and a third outer diameter ring 103 distributed from inside to outside, the above-mentioned position-limiting pressing part 11 is located at the position of the first outer diameter ring 101, the locking mechanism 4 is located at the position of the second outer diameter ring 102, and the pressing section 13 is located at the position of the third outer diameter ring 103, a slide way 104 is formed between the first outer diameter ring 101 and the second outer diameter ring 102, and the slide way 104 is formed by the combination of the overlapped parts of the notch part 15, the position-limiting pressing part 11 and the supporting part 12.

The slide way 104 is communicated with the movable passage 5, and when the socket is assembled, the lower end of the socket 3 enters the movable passage 5 from top to bottom, and then the upper end, namely the rotating fulcrum 31, is in contact with the support part 12 and then translates along the slide way 104, so that the assembly is convenient.
