[0013] Reference Figure 1 This utility model discloses a chain opening device, including: a cover 10, a roller 30, a sprocket chain 60, a sleeve screw 70, a chain tensioning rod 80, a first track plate 40, a second track plate 50, a reduction motor 90, and a bracket 20.

[0014] The bracket 20, the second track plate 40, and the geared motor 90 are connected to the external mechanism. When the cover 10 is closed, it is placed on the external mechanism to realize the installation and positioning of the bracket 20, the geared motor 90, the cover 10, and the second track plate 40.

[0015] A first track plate 40 is provided above the bracket 20, and is fixedly connected to the first track plate 40 to realize the installation and positioning of the first track plate 40.

[0016] A connecting plate 11 and a connecting plate 12 are provided on one side of the cover 10. The top of the cover 10 is fixedly connected to the connecting plate 11 and the connecting plate 12. The connecting plates are located at both ends of one side of the cover to realize the installation and positioning of the connecting plates.

[0017] The upper parts of the connecting plate 11 and the connecting plate 2 are respectively provided with roller 30 and roller 31. The connecting plate is fixedly connected to the roller. The roller 30 and roller 31 are initially installed at the starting point of the first track groove 41 to realize the installation and positioning of roller 30 and roller 32.

[0018] A roller 32 is provided on one side of the cover 10. The cover 10 is fixedly connected to the roller 32 to realize the installation and positioning of the roller 32.

[0019] The first track plate 40 is provided with a sprocket and chain mechanism, including: a driving sprocket 62, a driven sprocket 60, and a chain 61. The driving sprocket 62 and the driven sprocket 60 are respectively installed in the driving sprocket mounting hole 43 and the driven sprocket mounting hole 42 of the first track plate 40. The chain 61 is installed on the driving sprocket 62 and the driven sprocket 60 and meshes with the driving sprocket 62 and the driven sprocket 60 to realize the positioning and installation of the driving sprocket 62, the driven sprocket 60, and the chain 61.

[0020] The chain 61 is not directly connected at the beginning and end. A sleeve screw 70 is provided at the break point. The sleeve screw 70 is connected to the chain 61 to realize the positioning and installation of the sleeve screw 70.

[0021] The lower part of the chain tensioning rod 80 is connected to the cover 10 connecting plate by double nuts, and the upper part is connected to the sleeve screw 70 by double nuts. This connection method can adjust the tension of the chain, so that the chain forms a closed loop, and realize the positioning and installation of the chain tensioning rod 80.

[0022] The sprocket chain is equipped with a drive shaft 64, and the coupling 63 axially fixes the motor shaft to the sprocket drive shaft 64, thereby achieving the positioning and installation of the coupling 63.

[0023] The first track plate 40 is provided with two track grooves 41, a driven sprocket mounting hole 42 and a driving sprocket mounting hole 43. The two track grooves 41 are provided with an inclination angle of 0~15°. The center lines of the driven sprocket mounting hole 42 and the driving sprocket mounting hole 43 are provided with an inclination angle, which is consistent with the inclination angle of the track grooves 41.

[0024] The second track plate 50 has an inclined track groove 51, the inclination angle of which is the same as that of the track groove 41 of the first track 40, and the two are parallel. When the track groove 41 of the first track plate is consistent with and parallel to the track groove 51 of the second track plate, the displacement of the cover 10 in the vertical and horizontal directions is always the same, ensuring that the plane of the cover 10 is always horizontal, and the vertical displacement of the cover 10 is only 0 to 0.268 times that in the horizontal direction, ensuring that the vertical displacement of the cover 10 is always within a small range and does not interfere with other external machinery.

[0025] See Figure 2 In this embodiment, roller 1 30, roller 2 31, and roller 3 32 are all provided with roller retaining rings 33. The diameter of the retaining rings 33 is larger than the width of the track. Rollers 1 30, roller 2 31, and roller 3 32 are located on both sides of the cover 10. Under the combined action of their roller retaining rings 33, the left and right movement of the cover 10 is restricted, ensuring that the cover 10 does not derail.

[0026] See Figure 1In this embodiment, the motor shaft outputs power to drive the drive sprocket 62 to rotate. At this time, the chain 61, which meshes with the drive sprocket 62 and the driven sprocket 60, runs in the direction of the inclination angle. The chain tension rod 80 connected to the chain 61 moves with the chain along the direction of movement of the chain 61. The chain tension rod 80 is connected to the cover 10. Pulling the cover 10 causes the roller 30 on the cover 10 to move in the vertical and horizontal directions along the track, thereby realizing the opening and closing of the cover 10.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
