The present invention provides a foldable curtain frame 10, as shown in fig. 1 and 2, comprising a frame 100 and a connecting device 200 disposed on the frame 100. Wherein the frame 100 includes a cross-beam assembly 110 and longitudinal rod assemblies 120, the cross-beam assembly 110 forming the top and bottom edges of the frame 100, and the longitudinal rod assemblies 120 forming the two side edges of the frame 100.

As shown in fig. 3 and 4, the connection device 200 includes: the driving assembly 210, the driven assembly 220 and the rotating shaft 230, wherein the driving assembly 220 and the driven assembly 230 are both disposed on the beam assembly 110, the driving assembly 210 and the driven assembly 220 are disposed opposite to each other, and the driving assembly 210 and the driven assembly 220 are rotatably connected with the rotating shaft 230 as a center. The linkage 200 acts as a "joint" for the beam assembly 110, and the folding of the beam assembly 110 is achieved by the cooperation between the driving assembly 210 and the driven assembly 220.

As shown in fig. 5 and 6, the main structure of the connection device 200 is as follows: the active assembly 210 includes a movable latch 211 and a main connector 212, and the movable latch 211 is mounted on the beam assembly 110 through the main connector 212. The driven assembly 220 includes a fixed catch 221 and a secondary connector 222, the fixed catch 221 is mounted on the beam assembly 100 through the secondary connector 222, and the movable catch 211 catches or disengages from the fixed catch 221.

When the folding mechanism is folded, the movable buckle 211 of the driving component 210 is separated from the fixed buckle 221 of the driven component 220, and the driving component 210 and the driven component 220 can rotate around the rotating shaft 230, so that the beam component 110 is folded; when in use, as shown in fig. 5, the movable buckle 211 and the fixed buckle 221 are clamped together, so that the driving component 210 and the driven component 220 are stably connected, the beam component 110 is kept in a supported state, and the curtain can be hung on the frame 100. The specific operating principle will be explained in detail below.

In this embodiment, as shown in fig. 5 and fig. 6, the fixed buckle 221 and the movable buckle 211 are both provided with barb structures 201, the two barb structures 201 are disposed oppositely, the movable buckle 211 is rotatably connected to the main connection member 212, and the movable buckle 211 and the main connection member 212 are further provided with torsion springs (not shown). Preferably, the movable catch 211 is provided with a pressing portion 213. When the hook is used, under the action of the torsion spring, the movable buckle 211 has a downward pressing trend, and the two barb structures 201 are clamped together, so that stable connection is realized; when the beam assembly 110 is folded, an external force is applied to the pressing portion 213 to rotate the movable buckle 211, so that the two barb structures 201 are separated, and the beam assembly 110 is folded. In one embodiment, the pressing portion 213 is further provided with an anti-slip pattern 214, which can increase the friction coefficient of the pressing portion 213 to prevent slipping during pressing.

In the present embodiment, as shown in fig. 2, the beam assembly 110 includes: the first cross beam 111 and the middle cross beam 112 are connected through a connecting device 200, and the second cross beam 111 and the middle cross beam 112 are connected through a connecting device 200. Specifically, one end of the first beam 111 is provided with a driven assembly 220, and the corresponding end of the middle beam 112 is provided with a driving assembly 210; similarly, one end of the second beam 113 is provided with a driven assembly 220, and the other end of the middle beam 112 corresponding to the driven assembly 210. Thus, as shown in FIG. 2, the beam assembly 110 may be folded in cooperation with the connection device 200.

The working of the foldable curtain border 10 of the present invention will now be explained with reference to the above structure:

when the foldable curtain frame 10 is used, the beam assembly 110 is in the state shown in fig. 1, and the first beam 111, the middle beam 112 and the second beam 113 are all in the same straight line. In the state of the connecting device 200 as shown in fig. 4 and 5, since the barb 201 of the movable buckle 211 is opposite to the barb 201 of the fixed buckle 221, and the barb 201 of the movable buckle 211 has a downward pressing tendency under the action of the torsion spring, the two barb 201 will be tightly clamped together. In this state, the driving assembly 210 and the driven assembly 220 cannot rotate relatively, i.e. the beam assembly 110 cannot be folded;

when the folding is to be performed, the connecting device 200 needs to be unlocked first. Specifically, the pressing portion 213 of the movable catch 211 is pressed, so that the movable catch 211 overcomes the elastic force of the torsion spring and rotates; after rotation, the barb 201 of the movable catch 211 will disengage from the barb 201 of the fixed catch 221, as shown in fig. 6. At this time, the driving assembly 210 and the driven assembly 220 may rotate relatively, and an external force is applied to the beam assembly 110, so that the driven assembly 220 rotates around the rotating shaft 230 (as shown in fig. 7), and the first beam 111, the middle beam 112, and the second beam 113 may rotate relative to each other, thereby implementing convenient folding of the beam assembly 110;

when it is desired to use the folded cross-beam assembly 110 again, the driven assembly 220 is rotated in the opposite direction, opening the folded cross-beam assembly. In the rotating process, the barb structure 201 of the fixed buckle 221 touches the barb structure 201 of the movable buckle 211, and then, under the action of external force, the barb structure 201 of the fixed buckle 221 transmits pressure to the movable buckle 211, so that the movable buckle 211 overcomes the elastic force of the torsion spring to perform avoiding action, and the barb structure 201 of the fixed buckle 221 enters the lower part of the barb structure 201 of the movable buckle 211, so that the two barb structures 201 are clamped together again, and thus, the first cross beam 111, the middle cross beam 112 and the second cross beam 113 are positioned on the same straight line, and the foldable curtain frame 10 is opened again, so that the convenient assembly of the foldable curtain frame 10 is realized.

The main working principle of the foldable curtain border 10 is now described.

In the present embodiment, the first beam 111, the middle beam 112, and the second beam 113 are all hollow structures, so that the total weight of the frame 100 can be reduced. Preferably, as shown in fig. 6, the connecting device 200 includes a built-in abutting member 202, the built-in abutting member 202 is disposed in the beam assembly 110, and the built-in abutting member 202 is connected to the main connecting member 212 or the sub connecting member 222. As shown in fig. 7, taking one of the connecting devices 200 as an example, the built-in abutting member 202 is disposed inside the first cross beam 111 and the middle cross beam 112 and is connected to the main connecting member 212 and the sub connecting member 222 by screws. The built-in abutting piece 202 provides a base for mounting the screw, and also provides support for the first cross beam 111 and the middle cross beam 112, so that deformation caused by stress is avoided.

In one embodiment, the longitudinal bar assembly 120 is a telescoping bar structure, such that the collapsible curtain border 10 of the present invention is telescopically adjustable in a longitudinal direction, further reducing the space required for carrying.

The present invention also provides a curtain frame 20, as shown in fig. 8, comprising the foldable curtain frame 10 and a leg device 300 used in cooperation therewith. Wherein, the leg device 300 includes: the bottom pole 310, the support main pole 320 and the support auxiliary pole 330, the bottom pole 310 is placed on the ground, and the bottom pole 310 is connected with the end of the support main pole 320. The foldable curtain frame 10 is mounted on the support main rod 320. One end of the auxiliary support rod 330 is hinged to the bottom rod 310, and the other end of the auxiliary support rod 330 is connected to the main support rod 320 through a locking assembly 340.

Preferably, as shown in fig. 9, the locking assembly 340 includes a cushion block 341 and a positioning bolt 342, the positioning bolt 342 penetrates through the cushion block 341, and the supporting main rod 320 is provided with a positioning hole 321 matching with the positioning bolt 342. In this way, the locking assembly 340 can be locked at a suitable position on the supporting main rod 320 according to actual needs.

In use, the foldable curtain frame 10 is erected on the main support rod 320, one end of the auxiliary support rod 330 is connected to the bottom rod 310, and the other end is connected to the main support rod 320 through the locking assembly 340, thereby forming a planar tripod, so that the stand bar device 300 can stably support the foldable curtain frame 10.

In one embodiment, the support rod 320 is a telescopic rod that can be adjusted up and down to change the height of the foldable curtain border 10. Preferably, the support sub-bar 330 is also a telescopic bar structure, as shown in fig. 10, the support sub-bar 330 includes: the locking device comprises a sleeve rod 331, a movable rod 332 and a locking screw 333, wherein the sleeve rod 331 is sleeved on the movable rod 332 in a sliding mode, and the locking screw 333 penetrates through the sleeve rod 331 and abuts against the movable rod 332. After the locking screw 333 is unscrewed, the sleeve rod 331 can slide relative to the movable rod 332; after the locking screw 333 is tightened, the sleeve rod 331 and the movable rod 332 cannot slide relative to each other. Thus, the retractable design of the main support rod 320 and the sub-support rod 330 can also reduce the size of the folded screen frame 20.

In summary, the foldable curtain frame 10 and the curtain frame 20 thereof of the present invention can not only meet the requirement of convenient carrying, but also be assembled conveniently and quickly, thereby improving the work efficiency of disassembly and assembly.
