[0005] To achieve the above object, the present invention provides the following technical solution: A synchronous clamping device for decorative paintings, comprising a device housing. At both ends of both sides of the device housing, connection ears for fixing to the wall are fixedly installed. A glass cover is provided at the front of the device housing. At the four corners on one side of the glass cover, insertion rods are fixedly installed. On one side of the four insertion rods, card holes are provided. At the four corners of the front of the device housing, insertion holes are provided. A partition is fixedly installed inside the device housing. A decorative painting body is provided between the device housing and the glass cover. At the top and bottom of the decorative painting body, two fixing pieces are respectively fixedly installed. On one side of the partition, four magnets are fixedly installed. At the four corners on one side of the partition, positioning holes are provided. On one side of the decorative painting body close to the partition, four iron discs are fixedly installed. At the four corners on one side of the decorative painting body close to the partition, positioning rods are fixedly installed. Openings are provided at the upper and lower parts of the partition. Four clamping plates are provided between the device housing and the decorative painting body. At the four corners inside the device housing and on the other side of the partition, there are card rods adapted to the four card holes. On the inner bottom of the device housing, a lower sprocket is rotatably installed through a support seat. On one side of the lower sprocket, a handwheel is fixedly installed. Above the lower sprocket and inside the device housing, an upper sprocket is provided. One side of the upper sprocket is rotatably connected to the inner wall of the device housing. A chain is meshed and connected between the upper sprocket and the lower sprocket. On the other side of the upper sprocket, a threaded rod is fixedly installed. One end of the threaded rod is rotatably connected to the partition. A threaded sleeve is threadedly connected to the surface of the threaded rod. Vertical bars are fixedly installed on the surface of the threaded sleeve. At both ends of one side of the vertical bar, support arms are fixedly installed through connecting rods. At both ends of the two support arms, pins are fixedly installed. On the surfaces of the four pins, hollow bars are sleeved. On one side of the four hollow bars, they are fixedly connected to the four clamping plates through transmission rods. Between the adjacent ends of the hollow bars, rotating shafts are fixedly installed. The two ends of the rotating shaft are respectively rotatably connected to the inner walls at both ends of the opening.

[0006] Preferably, two sliding sleeves are respectively fixedly installed on the surfaces of the support arms. Inside the sliding sleeves, sliding rods are inserted. One ends of the sliding rods are fixedly connected to the inside of the opening through fixed seats. The other ends of the sliding rods are fixedly connected to the inner wall of the device housing.

[0007] Preferably, cross bars are fixedly installed at both ends of the vertical bar. At both ends of the sides where the two cross bars are away from each other, pushing plates are fixedly installed. The inclined surfaces at one ends of the four pushing plates are closely attached to rollers. At one ends of the rollers, moving rods are fixedly installed. The ends of the four moving rods away from the pushing plates are respectively fixedly connected to the four card rods.

[0008] Preferably, mounting seats are movably sleeved at one ends of the surfaces of the moving rods. One ends of the four mounting seats are fixedly connected to the partition. Springs are sleeved at the other ends of the surfaces of the four moving rods. Both ends of the four springs are respectively fixedly connected to the mounting seats and the rollers.

[0009] Preferably, two limiting sleeves are fixedly installed on the sides of the two cross bars away from each other. Limiting rods are inserted into the interiors of the four limiting sleeves, and both ends of the four limiting rods are fixedly connected to the partition board and the inner wall of the device housing respectively.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] (1) During installation, the operator places the decorative painting body into the interior of the device housing, inserts the four positioning rods into the four positioning holes to determine the installation position, and at the same time makes the four magnets magnetically adsorb the four iron discs to preliminarily fix the decorative painting body. Then, the operator inserts the four insertion rods on the glass cover into the four insertion holes. Immediately afterwards, the operator rotates the handwheel to drive the lower sprocket to rotate along the support base. When the lower sprocket rotates, it drives the upper sprocket to rotate through the chain, and the upper sprocket drives the threaded sleeve to move through the threaded rod.

[0012] When the threaded sleeve moves, it drives the two support arms to move through the two connecting rods. When the two support arms move, they drive the four sliding sleeves to slide along the surfaces of the four sliding rods, improving the stability of the movement of the two support arms. When the two support arms move, they both drive the four hollow bars to rotate along the two rotating shafts through the four pins. When the four hollow bars rotate, they drive the two driving rods located in the upper part to rotate clockwise and simultaneously drive the two driving rods located in the lower part to rotate counterclockwise. When the four driving rods rotate, they drive the four clamping plates to rotate and clamp the four fixing pieces, thus synchronously completing the fixation of the decorative painting body.

[0013] (2) While the vertical bars move, they also drive the four pushing plates to move through the two cross bars. When the two cross bars move, they drive the four limiting sleeves to slide along the surfaces of the four limiting rods, improving the stability of the movement of the two cross bars. When the four pushing plates move, they push the four moving rods to move along the interiors of the four mounting seats through the four rollers and simultaneously squeeze the four springs, so that the four moving rods have the function of elastic reset. When the four moving rods move, they drive the four clamping rods to be inserted into the four clamping holes on the four insertion rods, thus synchronously positioning the glass cover.

[0014] (3) The synchronous clamping device for the decorative painting can synchronously clamp the decorative painting and synchronously position the protective cover, which is convenient for the operator to use. Description of the Drawings
