DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail in combination with the drawings and examples.

[0021] In one embodiment, as shown in Figures 1-4 A portable exhibition device, comprising a U-shaped frame 1, the upper end of the U-shaped frame 1 is provided with a placing groove 2, the placing groove 2 is symmetrically provided with a clamping structure 3 on the left and right sides inside, and the corner of the U-shaped frame 1 is provided with a connecting structure 4 for connecting another U-shaped frame 1.

[0022] In this embodiment, in use, first, a plurality of U-shaped frames 1 are connected by the connecting structure 4, then the paintings to be exhibited are inserted into the placing groove 2 from top to bottom, and the clamping structure 3 fixes the paintings, so that the exhibition is carried out, which is beneficial to people's appreciation.

[0023] In an alternative embodiment, the clamping structure 3 comprises a spring groove one 301, the spring groove one 301 is provided in the inner wall of the placing groove 2, a movable plate one 303 is slidably arranged in the inner cavity of the spring groove one 301, a clamping block 304 is fixed to one end of the movable plate one 303 close to the placing groove 2, a reset spring one 302 is fixed to the other end of the movable plate one 303, and the other end of the reset spring one 302 is fixedly connected with the inner wall of the spring groove one 301.

[0024] It should be noted that the top end of the clamping block 304 is provided with an inclined surface, so as to facilitate the insertion of the paintings into the placing groove 2. When the paintings are inserted into the placing groove 2, the paintings will push the clamping block 304 and the movable plate one 303 to move inward, compressing the reset spring one 302. When the paintings are completely inserted, the elastic force of the reset spring one 302 will make the clamping block 304 tightly adhere to the paintings, achieving fixation.

[0025] In an optional embodiment, the connecting structure 4 comprises a side groove 401 opened at the corner of the U-shaped support 1, and an upper groove 402 and a lower groove 403 are respectively opened at the upper and lower ends of the inner wall of the side groove 401, the upper connecting block 404 is detachably installed inside the upper groove 402, the upper connecting block 404 is fixedly installed on the outer wall of the upper circular rod 405, the plug rod 406 is fixed at the bottom end of the upper circular rod 405, the lower connecting block 407 is detachably installed inside the lower groove 403, the lower connecting block 407 is fixed on the outer wall of the lower circular rod 408, the plug groove 409 matched with the plug rod 406 is opened at the top end of the lower circular rod 408, and the limiting component 41 is arranged inside the bottom end of the plug rod 406 and the plug groove 409.

[0026] It should be noted that the upper groove 402 and the lower groove 403 are respectively located at the upper and lower ends of the side groove 401, and are used for installing the upper connecting block 404 and the lower connecting block 407. The upper connecting block 404 and the lower connecting block 407 are respectively fixed on the outer walls of the upper circular rod 405 and the lower circular rod 408, wherein the bottom end of the upper circular rod 405 is fixed with the plug rod 406, and the top end of the lower circular rod 408 is provided with the plug groove 409 matched with the plug rod 406. Through the cooperation of the plug rod 406 and the plug groove 409, the connection of the two U-shaped supports 1 can be realized, and the cylindrical cooperation mode is adopted for the design of the plug rod 406 and the plug groove 409, so as to realize the rotation flexibility of the U-shaped support 1 after connection.

[0027] In an optional embodiment, the limiting component 41 comprises a fixed rod 411 fixed at the bottom end of the plug rod 406 and a spring groove two 414 opened in the inner wall of the plug groove 409, the bottom end of the fixed rod 411 is fixed with a fixed cone block 412, the outer wall of the fixed rod 411 is slidably provided with a movable cone block 413, the inside of the spring groove two 414 is slidably provided with a movable plate two 416, one end of the movable plate two 416 close to the plug groove 409 is fixed with a limiting block 417, the other end of the movable plate two 416 is fixed with a reset spring two 415, and the other end of the reset spring two 415 is fixedly connected with the inner wall of the spring groove two 414.

[0028] It should be noted that the top end of the limiting block 417 is provided with an inclined surface, the lower end of the movable cone block 413 is a wider base, and the upper end of the fixed cone block 412 is a wider base. When the insertion rod 406 is inserted into the insertion slot 409, the fixed cone block 412 will first press the limiting block 417, and the reset spring 415 will be compressed. When the fixed cone block 412 moves below the limiting block 417, the reset spring 415 will rebound, and the limiting block 417 will reset, thereby avoiding the disconnection of the upper circular rod 405 and the lower circular rod 408. When it is necessary to separate the upper circular rod 405 and the lower circular rod 408, the upper circular rod 405 is pressed downward, the fixed rod 411 moves downward, the top surface of the movable cone block 413 abuts against the bottom surface of the insertion rod 406, and then the upper circular rod 405 is pressed downward again. The movable cone block 413 will press the limiting block 417, and the reset spring 415 will be compressed. The movable cone block 413 slides downward until it contacts the fixed cone block 412, and the upper circular rod 405 is moved upward, thereby realizing the separation of the upper circular rod 405 and the lower circular rod 408.

[0029] The above embodiment discloses a portable exhibition device. A painting is aligned with the placement slot 2 of the U-shaped frame and is pushed in. The edge of the painting contacts the inclined clamping block 304, the clamping block 304 and the movable plate 303 are pushed to move inward, and the reset spring 302 is compressed. After the painting is completely inserted, the reset spring 302 rebounds, the clamping block 304 is pushed to tightly abut against the edge of the painting, and fixing is realized. The U-shaped frame 1 is aligned, the insertion rod 406 is aligned with the insertion slot 409, and the insertion rod 406 is inserted by being gently pushed. The cylindrical design of the insertion rod 406 and the insertion slot 409 provides rotation flexibility. When the insertion rod 406 is inserted, the fixed cone block 412 contacts the inclined limiting block 417, the limiting block 417 and the movable plate 416 are pushed to move inward, and the reset spring 415 is compressed. When the fixed cone block 412 moves below, the reset spring 415 rebounds, the limiting block 417 is pushed to tightly abut below the fixed cone block 412, and a stable connection is formed. When separation is needed, the upper circular rod 405 is pressed downward, the top surface of the movable cone block 413 abuts against the bottom surface of the insertion rod 406. The movable cone block 413 is pressed to press the limiting block 417 again. At this time, the upper circular rod 405 can be moved upward, the insertion rod 406 is pulled out, and separation is realized.

[0030] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
