Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with accompanying drawing:

[0032] Such as figure 1 , 2 As shown, a self-expanding diameter protection plate, which includes an upper fixed plate 11, a middle layer diameter expansion plate, and a lower layer cam plate 33, which are stacked sequentially from top to bottom, and the middle layer diameter expansion plate is formed by splicing three fan-shaped plates 22, The angle of each fan-shaped disk is 120°, and the opposite sides of the apex of the fan-shaped plate 2 are joined together to form a disk-shaped middle-level expansion disk. A screw 4 as a slider is perforated on each fan-shaped plate 2 , the screw 4 is located on the symmetry axis of the corresponding fan-shaped plate 2, the position of the screw 4 is close to the apex of the corresponding fan-shaped plate 2, and the screw 4 on the upper fixed disk 1 corresponds to the screw 4 on the middle expansion disk. There are a plural...

Abstract

The invention discloses a self-expanding protection disc. The self-expanding protection disc comprises an upper-layer fixing disc, a middle-layer expanding disc and a lower-layer cam disc which are sequentially stacked from top to bottom. The middle-layer expanding disc is formed by combining and splicing the side faces of a plurality of fan-shaped plates, and a screw serving as a sliding block penetrates each fan-shaped plate and is located on the symmetric axis of the corresponding fan-shaped plate. A plurality of guiding strip holes are formed in the positions, corresponding to the screws, of the upper-layer fixing disc and extend outwards along the radius of the upper-layer fixing disc, and the top ends of the screws are inserted in the guiding strip holes. A plurality of rotary pushing strip holes are formed in the positions, corresponding to the screws, on the lower-layer cam disc, the rotary pushing strip holes are strip-shaped openings with one ends opposite to the screws and the other ends obliquely extending towards the edge of the lower-layer cam disc, and the bottom ends of the screws are inserted in the rotary pushing strip holes. By means of the three-layer structure, the upper-layer fixing disc serves as a sliding way and also has a function of protecting the structures at the lower portion, and after the self-expanding protection disc is placed in a crucible, the diameter can be changed at will, and the coating work is greatly facilitated.

Description

technical field [0001] The invention relates to the field of crucible manufacturing equipment, in particular to a self-expanding diameter protection plate. Background technique [0002] In the production of quartz crucible, it is necessary to spray coating on the surface of quartz crucible. According to the requirement, the coating is divided into whole coating and partial coating. In partial coating, it is only necessary to coat the top and bottom 5cm of the crucible. Layer, so it is required to make a shield to cover the lower part of the crucible, so as not to be sprayed by the coating liquid, and the existing shield is only to use the original plate with the same caliber as the quartz crucible to be embedded in the quartz crucible, which causes the following problems: [0003] ① It is difficult to take out the shielding plate; [0004] ②Manually cut the baffle plate, the edge is relatively rough, and there is a gap between the inner wall of the quartz crucible, resultin...
