Description

Technical Field

[0001] This invention relates to a cover plate, and more particularly to a cover plate with a surface flatness that can be quickly adjusted. Background Technology

[0002] For cover plates that require consideration of the positioning surface, the smoothness requirement between the cover plate and the positioning surface is usually achieved directly by designing a reasonable height for the cover plate support. However, this method has certain drawbacks: if deviations occur during the manufacturing or assembly process, the cover plate's shape cannot be adjusted, resulting in high rework costs. Summary of the Invention

[0003] The technical problem this invention aims to solve is to provide a cover plate with rapidly adjustable surface flatness, which addresses the difficulty in adjusting the smoothness of the cover plate and the pneumatic outer surface. The assembly process of this cover plate is simple, effectively improving the smoothness requirements of the cover plate and the pneumatic outer surface, reducing assembly and debugging time, reducing rework time, and resulting in high economic benefits.

[0004] To solve the above problems, the specific technical solution of the present invention is as follows:

[0005] A cover plate with adjustable surface flatness includes a cover plate, a cover plate support, connecting bolts, a torsion spring, a stop, and a support.

[0006] The cover plate, torsion spring, and cover plate support are connected by connecting bolts, and the cover plate support is finally fixed to the support.

[0007] The cover plate support and the opposing surfaces of the support are all provided with teeth.

[0008] The torsion spring allows the cover to always open outwards without the action of external force.

[0009] The relative position of the cover plate can be adjusted by gradually adjusting the relative positions of the cover plate support and the teeth of the support.

[0010] The angle at which the cover plate opens outward is determined by the relative positions of the stop, the cover plate support, and the teeth of the support, ultimately ensuring aerodynamic smoothness between the upper and lower parts of the cover plate and the positioning surface.

[0011] The torque of the torsion spring can be adjusted by the magnitude of the opening force of the cover plate.

[0012] The cover plate operates as follows: when the cover plate does not need to be opened, it remains smooth against the positioning surface under the action of the torsion spring, the stop, the cover plate support, and the support; when the cover plate needs to be opened, the lower part of the cover plate can be manually pressed to open the cover plate around the connecting bolt; after the manual pressing is released, the cover plate automatically returns to the position required to maintain smoothness against the positioning surface under the action of the torsion spring.

[0013] The tooth shape is an isosceles triangle, and the support member is an L-shaped structural member with an obtuse interior angle.

[0014] The beneficial effects of this invention are:

[0015] This invention effectively solves the problem of difficult adjustment of the smoothness of the cover plate and the pneumatic outer surface by adopting the combination of the stop and the toothed plate. Moreover, the cover plate is simple to assemble and adjust, easy to carry out practical application, and has high economic benefits. Attached Figure Description

[0018] Example 1:

[0019] A cover plate with adjustable surface flatness includes a cover plate 2, a cover plate support 3, a connecting bolt 4, a torsion spring 5, a stop 6, and a support 7.

[0020] The cover plate 2, torsion spring 5 and cover plate support 3 are connected by connecting bolts 4, and the cover plate support 3 is finally fixed to the support 7.

[0021] The cover plate support 3 and support 7 are both provided with teeth on their opposite surfaces.

[0022] The torsion spring 5 can keep the cover plate 2 open outwards without the action of external force.

[0023] The relative position of the cover plate 2 can be adjusted by gradually adjusting the relative positions of the teeth of the cover plate support 3 and support 7.

[0024] The angle at which the cover plate 2 opens outward is determined by the relative position of the toothed part of the stop 6, the cover plate support 3, and the support 7, and ultimately ensures that the upper and lower parts of the cover plate 2 and the positioning surface are pneumatically smooth.

[0025] The torque of the torsion spring 5 can be adjusted by the magnitude of the opening force of the cover plate 2.

[0026] The operating principle of the cover plate 2 is as follows: when the cover plate 2 does not need to be opened, the cover plate 2 maintains smoothness with the positioning surface under the action of the torsion spring 5, the stop 6, the cover plate support 3 and the support 7; when the cover plate 2 needs to be opened, the lower part of the cover plate 2 can be manually pressed to open the cover plate 2 around the connecting bolt 4; after the manual pressing is released, the cover plate 2 automatically returns to the position required to maintain smoothness with the positioning surface under the action of the torsion spring 5.

[0027] Example 2:

[0028] like Figure 1 As shown, a cover plate with quickly adjustable surface flatness is provided. The cover plate mainly consists of a cover plate, a cover plate support, connecting bolts, a torsion spring, a stop, and other supporting components. When the cover plate does not need to be opened, it maintains smoothness with the positioning surface under the action of the torsion spring, the stop, the cover plate support, and the supporting components. When the cover plate needs to be opened, manually pressing the lower part of the cover plate will open it around the connecting bolts. After manually pressing and releasing, the cover plate automatically returns to the position required to maintain smoothness with the positioning surface under the action of the torsion spring.
