[0026] The present utility model will be further described below in conjunction with the accompanying drawings.

[0027] Embodiment 1

[0028] As Figure 1-4 shown, a soft light box wire clamping disc is composed of a chuck 100 and a locking member 200. Among them, the chuck 100 is used to install the wire frame, and the locking member 200 is movably arranged on the circumferential surface of the chuck 100, and each locking member 200 is respectively in corresponding cooperation with the wires of the wire frame. The wire frame is composed of several wires, and the outer side of the wire frame is coated with a reflective cloth and a soft light cloth to form the box body part of the soft light box. The chuck 100 is an annular disc structure, composed of an upper disc 101 and a lower disc 102. An installation seat 103 is fixedly arranged on the inner ring of the upper disc 101, and the installation seat 103 extends upward above the upper disc 101, and is installed with a bracket and a lamp body through the installation seat 103. A hanging buckle 104 is arranged on the inner ring of the lower disc 102.

[0029] A limiting groove 110 is arranged on the edge of the chuck 100, and the locking members 200 are respectively arranged in the limiting groove 110. Sliders 210 are arranged on both sides of the locking member 200, a locking end 220 is arranged at the rear end of the locking member 200, and a wire connection hole is arranged at the front end of the locking member 210. The wires of the wire frame are inserted into the wire connection hole to form a fixed connection. Travel grooves 120 for cooperating with the sliders 210 are arranged on both side walls of the limiting groove 110, and a jack 130 is arranged at the bottom. In the locked state, the locking end 220 is inserted into the jack 130, and the locking member 200 is fixed and does not rotate. In the movable state, the locking end 220 disengages from the jack 130 and can be flipped with the slider 210 as an axis.

[0030] In this embodiment, the locking end 220 is a cylindrical structure, integrally formed on the locking member 200, and the slider 210 and the locking member 200 are of a split structure. The slider 210 is a cylinder and is inserted and arranged on the locking member 200. Specifically, a through hole 230 is arranged on the locking member 200, and the slider 210 is inserted and fixed in the through hole 230. Both ends of the slider 210 are respectively limited in the travel groove 120. When the locking member 200 moves horizontally, the slider 210 moves in the travel groove 120 to ensure that the locking member 200 does not fall off from the chuck 100.

[0031] In order to ensure that the locking member 200 can be moved to change the state of the wire frame, the movable distance of the travel groove 120, that is, the length of the travel groove, is not less than the insertable depth of the jack 130, so that the locking end 220 can completely disengage from the jack 130.

[0032] Another embodiment is that the locking end 220 is a prism structure, and the cross-sectional shape of the jack 130 corresponds to that of the locking end 220. Specifically, when the locking end 220 is a triangular prism, the cross-sectional shape of the jack 130 is triangular and is correspondingly arranged with the locking end 220 so that the locking end 220 can be inserted into the jack 130.

[0033] Another embodiment is that the locking end 220 is a frustum structure with a diameter uniformly decreasing from the inside to the outside, the jack 130 is a circular hole, and the diameter of the outer end face circle of the locking end < the diameter of the circular hole of the locking end is less than the diameter of the inner end face circle of the locking end. On the premise of ensuring that the locking end can be inserted into the jack 130, an interference fit can also be formed between the locking end 220 and the jack 130, and the connection is more stable in the locked state.

[0034] Another embodiment is that the slider 210 is integrally formed on the locking member 200. And the sliders 210 on both sides of the locking member 200 are symmetrically distributed with respect to the locking member 200 as the axis of symmetry.

[0035] During use, unfold the soft light box, then press the locking member 200 connected with the steel wire inward so that the locking end 220 is inserted into the jack 130. At this time, the box body of the soft light box is in a locked state. When it is necessary to put away the soft light box after use, pull out the locking end 220 of the locking member from the jack 130, and the steel wire can rotate in the limiting groove 110 following the locking member to complete the storage of the soft light box.

[0036] After the steel wire frame is unfolded, only by inserting the locking end of the locking member into the jack, the locking and positioning of the steel wire frame can be realized. And when it is necessary to put away the steel wire frame for storage, only need to pull out the locking member outward to withdraw the locking end from the jack. At this time, the locking member can rotate around the slider in the limiting groove to realize the reset and storage of the steel wire frame. The structure is simple and easy to use. It solves the problem that in the traditional soft light box, the locking state of the steel wire frame needs to be controlled by buttons or switches, reduces the assembly cost in the production process, and improves the production efficiency.

[0037] Embodiment 2

[0038] Combined with Figure 5 As shown, the difference from Embodiment 1 is that hanging ears 240 for connecting soft light box fabrics such as reflective cloth and soft light cloth are provided on the outer wall of the locking member 200, which further improves the stability of the light box and prevents the soft light box fabric from falling off the steel wire frame.

[0039] Embodiment 3

[0040] Combined with Figure 6As shown, the difference from Embodiment 1 is that an embedding groove 250 is provided on the locking end 220 of the locking member 200. In this embodiment, connecting ribs that cooperate with the embedding groove 250 are provided in the insertion hole 130 of the chuck 100. When the locking end 220 is inserted into the insertion hole 130, the connecting ribs are embedded and clamped in the embedding groove 250 to form a connection, which can prevent the locking member 200 from falling off from the insertion hole 130. When releasing the connection state, pull the box body outwards to apply a certain pulling force to the locking member, and the connecting ribs will disengage from the embedding groove 250.

[0041] As a preferred embodiment, on the locking member 200 of this embodiment, a lug 240 structure as shown in Figure 5 can also be provided.
