[0032] Example 1

[0033] like Figure 1-4 As shown, the present invention proposes a picture frame and drawing board fixing clamp, which includes an easel and an adjusting rod;

[0034] The easel is equipped with an extension frame at the top for extending its length when in use;

[0035] The adjusting rod is rotatably mounted on the top of the extension frame. One end of the adjusting rod, located on the front side of the extension frame, is equipped with a pressure block 5 that is connected to the extension frame and, in use, presses and fixes the picture frame and painting board placed on the easel.

[0036] In this embodiment, by setting an extension frame at the top of the easel, different sizes of picture frames and canvases can be placed on the frame 1. At the same time, by installing a rotatable adjusting rod on the extension frame, the front end of the adjusting rod is connected to a pressure plate, so that the adjusting rod drives the pressure plate to move towards the extension frame and fix the picture frames and canvases on the front side of the frame 1, thereby achieving the pressing and fixing of the picture frames and canvases, effectively preventing the middle of the picture frames and canvases from shifting and improving the stability of painting.

[0037] Example 2

[0038] like Figure 1-2 As shown, the picture frame and drawing board fixing clamp proposed by this utility model differs from that of embodiment one in that the easel includes a frame body 1, a support rod 2 and a support rod 3.

[0039] The middle part of frame 1 has at least three connecting columns;

[0040] The support rod 2 is slidably installed on the connecting columns on both sides of the frame 1 and located on the front side of the frame 1. The rear side of the support rod 2 has a hand-tightening screw that is threaded to the support rod 2 and passes through the support rod 2 and connects to the frame 1. This screw is used to adjust the position of the support rod 2 during use so that the picture frame and the picture board are located at different heights on the frame 1.

[0041] The support rod 3 is rotatably mounted on the connecting column in the middle of the frame 1 and is located on the rear side of the frame 1.

[0042] In this embodiment, the frame and drawing board can be fixed at multiple angles by rotating the support rod 3, which enhances the flexibility of use. The support rod 2 slides on the frame 1 to meet different painting needs.

[0043] Example 3

[0044] like Figure 2-3 As shown, the picture frame and drawing board fixing clamp proposed by this utility model differs from that of embodiment one in that the extension frame includes a mounting rod 4, a connecting seat 7, and a sliding rod 16.

[0045] The slide rod 16 is inserted into the middle of the connecting column of the frame 1. The slide rod 16 is arranged one-to-one with the connecting column of the frame 1. The slide rod 16 is fixedly connected to the frame 1 by hand-tightening bolts, so that the slide rod 16 is placed in different positions in the frame 1.

[0046] Mounting rod 4 is installed at the top of slide rod 16 and its front side is flush with the front side of frame 1;

[0047] The number of connecting seats 7 is at least two. The two connecting seats 7 are symmetrically installed on the top of the mounting rod 4 with respect to the center of the frame 1 and connected to the adjusting rod.

[0048] In this embodiment, the sliding rod 16 is inserted into the connecting rod of the frame 1, which adjusts the distance between the mounting rod 4 and the top of the frame 1, thereby adjusting the distance between the mounting rod 4 and the support rod 2. This allows different sized picture frames and panels to be placed on the support rod 2. Through the symmetrical installation of the connecting seat 7, the adjusting rod drives the pressure plate to apply pressure to both sides of the picture frame and panel, effectively preventing the picture frame and panel from moving and further improving the stability during painting.

[0049] Example 4

[0050] like Figure 3-4 As shown, the picture frame and drawing board fixing clamp proposed by this utility model differs from that of embodiment one in that the adjusting rod includes a bolt 6, a knob 8 and a screw 15.

[0051] Bolt 6 is threaded into the middle of connector 7;

[0052] The knob 8 is located on the front side of the pressure block 5 and passes through the pressure block 5 to be connected to the bolt 6;

[0053] Screw 15 is located in the middle of knob 8 and its end passes through knob 8 to connect with bolt 6.

[0054] In an optional embodiment, the knob 8 is provided with a connecting groove 12 on its side and a rectangular block 13 is provided at one end of the bolt 6. When the knob 8 and the bolt 6 are installed together, the rectangular block 13 is accommodated in the connecting groove 12, so that the knob 8 and the bolt 6 can be detachably connected. When in use, the force generated by the rectangular block 13 and the inner wall of the connecting groove 12 will cause the knob 8 to drive the bolt 6 to rotate.

[0055] In an optional embodiment, an anti-slip strip 14 is provided on the outer circular surface of one end of the knob 8 to prevent slippage when the knob 8 is rotated.

[0056] In this embodiment, the bolt 6 and the knob 8 are connected by the cooperation of the rectangular block 13 and the connecting groove 12, and the bolt 6 and the knob 8 are connected as one piece by the screw 15. The knob 8 drives the bolt 6 to rotate on the connecting seat 7 on the front side of the pressure block 5, so that the pressure block 5 can press and release the picture frame and the picture board, ensuring that the picture board is stable and does not shake during the painting process, improving the user experience, and making the adjustment of the pressure block 5 more convenient.

[0057] Example 5

[0058] like Figure 3-4 As shown, the picture frame and drawing board fixing clamp proposed by this utility model differs from that of Embodiment 1 in that a stepped groove 10 is provided on the rear side of the pressure block 5 and the front side of the mounting rod 4, and a gasket 9 is provided on the inner side of the stepped groove 10. The gasket 9 is used to separate the pressure block 5 from the picture frame and drawing board during use, so as to prevent the pressure block 5 from causing indentations on the picture frame and drawing board.

[0059] In an optional embodiment, the thickness of the shim 9 is less than the depth of the stepped groove 10, so that the stepped groove 10 contacts the top of the picture frame panel, so that the picture frame panel is placed horizontally on the support rod 2.

[0060] In an optional embodiment, a limiting plate 11 is provided on the rear side of the pressure block 5 and on both sides of the connecting seat 7. The limiting plate 11 is slidably connected to the upper end face of the mounting rod 4 to prevent the pressure block 5 from rotating with the knob 8 during use.

[0061] In this embodiment, when the knob 8 is rotated inside the pressure block 5, the pressure block 5 generates force through the limiting plate 11 and the top of the mounting rod 4 to prevent the pressure block 5 from rotating. At the same time, the pressure block 5 drives the pad 9 to fit tightly against the picture frame and the picture board, and makes the picture frame and the picture board fit and connect with the inner wall of the stepped groove 10 in the stepped groove 10, ensuring that the picture frame and the picture board remain horizontal during the painting process, further improving the accuracy and comfort of painting.

[0062] In this invention, the support rod 3 is rotatably connected to the frame 1, allowing the support rod 3 to support the frame 1 and the support rod 2 to slide on the frame 1. Simultaneously, the mounting rod 4 is positioned via the sliding rod 16, allowing different sizes and positions of picture frames and panels to be placed on the frame 1 via the support rod 2. The top of the stepped groove 10 is in close contact with the top of the picture frame and panel, placing the picture frame and panel horizontally. The bolt 6 is connected to the knob 8 via the cooperation of the rectangular block 13 and the connecting groove 12, and the bolt 6 and knob 8 are integrated via screws 15. The knob 8, located in front of the pressure block 5, drives the bolt 6 to rotate on the connecting seat 7. The limiting plate 11 on the rear side of the pressure block 5 causes the knob 8 to move the pressure block 5 towards the picture frame and panel, and the pressure block 5 drives the pad 9 to press the picture frame and panel firmly, ensuring the picture frame and panel are stable and do not wobble during painting, preventing indentations on the picture frame and panel, and improving the painting experience.

[0063] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
