Description of the invention: [Technical field to which the invention pertains] j The present invention relates to an improved structure of a combined picture frame, in particular to a detachable, portable and reusable canvas frame, or a The tensioning mechanism, Γ can adjust the size of the frame and the tension of the cloth. j [Prior Art] Press, the conventional oil painting frame is made up of wooden frames. The user should use the tongs to first tighten the oil bra on the frame, and then use the nail to fix the canvas. On the frame, start painting again. However, the practice of fixing the canvas to the frame is quite cumbersome and time consuming. Obviously, it requires a considerable skill to effectively fix the crepe on the sash. However, when the sputum is good, the sling is usually nailed. The frame of the oil is not disassembled, and the frame with the nails is filled with the chamber, which is extremely space-consuming and the canvas frame needs to be purchased repeatedly, which also causes waste of money. • Sub-press, US Patent Publication No. 854, “Expanded Canvas Structure”, which consists of four joints and four frame strips, but the adjustment of the frame made up of joints and frame strips is not easy. Cloth_in the frame does not effectively fix the canvas and disassemble it. Furthermore, the "expanded canvas frame structure" disclosed in the U.S. Patent No. 3,978,905, which is also composed of four joint members and four frame strips, has the same fixtures, but the structure is extremely complicated to manufacture and the buttons are not easy to install, and the cloth is disassembled and assembled. It is also extremely unchanged. In addition, the "expandable frame structure with expansion device" disclosed in the Wu Guo Patent Publication (4) 5113611 is also composed of four-piece and four-frame bars, although it also has the joint member and frame 5 200800079. It is not easy to manufacture and assemble, and it is extremely inconvenient to disassemble the canvas without a jig. After the inventor's painstaking research for many years, I developed the patent-free No. 578524 nail-free replaceable canvas frame, which consists of a number of joints and frame bars, and has a 昼 _ fixed-cut canvas. And the size of the telescopic frame is difficult to draw and the tension on the cloth is 'but the fixing of the cloth is complicated and the assembly is inconvenient. * The adjustment of the telescopic piece is also extremely inconvenient. It can be seen that there are still many shortcomings in the above-mentioned household items, which is not a good designer's and needs to be improved. In view of the shortcomings derived from the above-mentioned conventional oil painting frame structure, the inventor of the present invention succeeded in researching and developing the frame structure of the oil painting frame after the improvement and innovation of the thinking and the painstaking research. SUMMARY OF THE INVENTION Accordingly, the main object of the present invention is to provide an improved structure of a composite bezel, which can facilitate the manufacture and assembly of the jig and save a lot of cost by the simple jig of the jig, and the canvas can be easily disassembled for carrying. And reduce the cost of buying the oil frame, and avoid the space occupied by the number of oil painting frames. Another object of the present invention is to provide an improved structure of a combined picture frame, which is easy to adjust the size of the picture frame and the tension of the canvas by the absence of the support mechanism. In order to achieve the above object, the improved structure of the combined picture frame of the present invention comprises a plurality of joint members, each of the joint members having a central block body, and an adjacent side edge of the center block body forms a plug portion; The strips are strip-shaped, each strip has two 6 200800079 mating portions, which are respectively located on both sides of the lengthwise direction of the strip for the plugging portion to be connected; a plurality of jigs are used to lose Live a rag. Furthermore, the _Wei mechanism may be separately provided on the plurality of joint members, and the struts mechanism may have an extension arm extending or extending, thereby adjusting the size of the frame and the tension of the canvas according to actual needs. [Embodiment] f first' Please refer to pictures - 2 and 3. The first, second and third figures are respectively a perspective exploded view, a partial exploded view and a partial combined view of the improved structure of the combined frame. A tarpaulin frame of the present invention comprises a plurality of joint members 1〇, a plurality of frame strips 2〇, and a plurality of clamps 30. The joint member 10 has a central block body 11 which can be formed of PP plastic. The two adjacent sides of the central block body n respectively form a plug portion, and the plug portion 12 is recorded by a red wire, and the joint member 1 is {) is made of L; the frame 2〇' is in the form of a strip, and the flange 21 and the strip 4 are respectively extended on the two sides, and a retaining edge 221 is extended inward from the end edge of the strip 22, The cross section of the frame strip 2 is slightly c-shaped to receive the groove 23' and the two sides of the frame strip 2 have the corresponding insertion portion 24 corresponding to the insertion portion 12 of the engaging member 1〇 for the two insertions. The connecting portions 12 are respectively inserted to form a whole frame. The engaging portion 24 can be a slot in the longitudinal direction. The structure of the missing 30' can be referred to the three-dimensional schematic diagram of the clamp shown in the fourth figure. The PP plastic is integrally formed, and has a set of heads 31 at one end thereof, the sleeves are formed with a notch 3 corresponding to the flange 21 of the frame strip 20 to fit over the flange 21, and the clamp 3 has a collet 32 at the other end. Just inside the rib 221 of the strip 22 of the frame 20, the ferrule 31 and the collet 32 are connected by a connecting piece 33, and the connecting piece 33 is suitably provided with a neck 34, so that The canvas 30 is more elastic, and the chuck 32 is extended to 200800079, and a pressing portion 321 is provided. The canvas frame is formed by the combination of the above components, and the canvas is fixed to the frame as shown in the fifth and sixth figures. First, the notch 311 of the clamp 3 ferrule 31 is placed on the flange 21 of the frame strip 20, and the canvas 4 反 is folded from the bottom surface of the frame 2 〇 to the accommodating groove 23 of the frame 20 over the dam 22 The clip 32 is placed in the accommodating groove 23 and is placed on the inner side of the rib 221 of the dam 22, so that the canvas can be fixed to the frame to easily fix the canvas to the frame. On the other hand, when the canvas 40 is to be removed, the pressing portion 321 can be pressed to disengage the cooling head 32 from the accommodating groove 23 to be separated from the rim 221 of the dam 22, so that the canvas can be easily taken out from the frame. Next, please refer to the seventh, eighth and ninth drawings, wherein the canvas frame further comprises a plurality of stretching mechanisms 50, and the stretching mechanism 50 is provided by the fastening member 51 mounted on the side of the flange 21 of the frame strip 20. The screw 52 fixed to the engaging member 1 and the threaded sleeve 5.3 are formed on the extending member 532 of the screw 52. The retaining member 51 is fixed to the inner side of the flange 21 of the frame strip 20, and is fixed by a rivet 511. The two screws 512 are formed; the screw 52, |- end is fixed to one of the engaging members 1 〇 and is fixed to the engaging member by a C-clip 521, and the other end has a knob 522. The extension member 53 is formed by pivoting a pair of arms 532 on both sides of a screw ring 531, and the end of the extension arm 53 has a notch 533 to abut the rivet 511 ° of the fastener 51. A combination of components and a canvas frame, which adjusts the level of the frame and 8 200800079 4 π away from the tenth figure, the rotating screw 52 moves the front and rear of the screw ring 531, and the sides of the ', 31 are pivoted The extension arm 532 is then retracted or stretched to drive the frame strip 20 of the joint H to move up and down, and the size of the frame and the cloth can be adjusted according to actual needs.
