[0003] For example, publication number CN106835057A, published on June 13, 2017, discloses a coated glass clamping mechanism comprising a substrate holder, a gasket, and a clamp. The substrate holder is used to support a glass substrate, the edge of which is secured to the substrate holder via the clamp. The substrate holder has a side that supports the glass substrate and is provided with, from top to bottom, a horizontal first surface, a vertical second surface, and a horizontal third surface. The first surface and the second surface are connected by a first transition surface, and the second surface and the third surface are connected by a second transition surface. The clamping device disclosed above is not easily movable when clamping different types of glass, making it less practical. Summary of the Invention

[0004] The purpose of this utility model is to provide a glass clamping device for a coating chamber that can conveniently and stably clamp different types of glass. The utility model facilitates movement into different coating chambers for clamping by means of connection holes on the clamping block, while the notch on the clamping block facilitates movement of the glass into the clamping slot, thereby enabling the clamping block to conveniently clamp the glass.

[0005] To achieve the above purpose, the technical solution adopted by the utility model to solve its technical problems is: a glass clamping device in a coating cavity, including a clamping block, a clamping slot is provided on the clamping block, a notch is provided on the clamping slot, and a connecting hole is provided on the clamping block.

[0006] As a further solution of the present invention, the connecting hole is a threaded hole.

[0007] As a further solution of the present invention, the clamping block is L-shaped, the connecting hole is arranged on one side of the clamping block, and the card slot is arranged on the other side of the clamping block.

[0008] As a further solution of the present invention, the outer side of the right angle of the clamping block is provided with a chamfer.

[0009] As a further solution of the present invention, the inner side of the right angle of the clamping block is provided with a rounded corner.

[0010] As a further solution of the present invention, there are two connecting holes, and the two connecting holes are arranged side by side on the clamping block.

[0011] As a further solution of the present invention, the cross section of the slot is rectangular, and the notch is arranged on a side close to the connecting hole.

[0012] The beneficial effects of the utility model are:

[0013] The clamping block is connected to the platform in the coating chamber through connecting holes and bolts, so that the clamping block can be easily moved to different coating chambers for clamping work, which has higher versatility. The glass is clamped into the clamping slot of the clamping block through the notch on the clamping block, thereby achieving stable placement of the glass in the coating chamber. The clamping block has a simple structure, is easy and quick to install, is easy to use, and has higher practicality.

[0014] The outer side of the right angle of the clamping block is provided with a chamfer, which makes it easier to move the clamping block into the coating fixture for installation; the inner side of the right angle of the clamping block is provided with a rounded corner, which prevents stress concentration and thus increases the strength of the clamping block.
