[0015] The present invention will be further described below in conjunction with specific embodiments.

[0016] The quartz rod locking device for two-dimensional material growth equipment of the present invention comprises a quartz rod 1, a support sleeve 2, an upper locking sleeve 3, a lower locking sleeve 4, an upper locking cap 5 and a lower locking cap 6;

[0017] The upper end of the support sleeve 2 has an upper end external thread of the support sleeve and an upper end inner conical surface of the support sleeve, and the lower end of the support sleeve 2 has a lower end external thread of the support sleeve and an inner conical surface of the support sleeve; the upper locking sleeve 3 has an upper locking sleeve outer conical surface, and a longitudinal elastic groove is provided on the upper locking sleeve 3; the lower locking sleeve 4 has a lower locking sleeve outer conical surface, and a longitudinal elastic groove is provided on the lower locking sleeve 4; the upper locking cap 5 has an upper locking cap inner thread, and the lower locking cap 6 has a lower locking cap inner thread; the inner conical surface of the upper end of the support sleeve and the outer conical surface of the upper locking sleeve have the same taper, and the inner conical surface of the lower end of the support sleeve and the outer conical surface of the lower locking sleeve have the same taper;

[0018] A supporting sleeve 2 is sleeved on the outside of the quartz rod 1, and a lower locking sleeve 4 and a lower locking cap 6 are sleeved on the outside of the lower end of the quartz rod 1. The inner conical surface of the lower end of the supporting sleeve is tightly attached to the outer conical surface of the lower locking sleeve, and the inner thread of the lower locking cap is screwed together with the outer thread of the lower end of the supporting sleeve. The upper bottom surface of the lower locking cap 6 is in contact with the lower end surface of the lower locking sleeve 4 and the lower end surface of the quartz rod 1, and the lower locking sleeve 4 holds the quartz rod 1 tightly.

[0019] An upper locking sleeve 3 and an upper locking cap 5 are mounted on the outside of the quartz rod 1 corresponding to the upper end position of the supporting sleeve 2. The inner conical surface of the upper end of the supporting sleeve is tightly attached to the outer conical surface of the upper locking sleeve. The outer thread of the upper end of the supporting sleeve is tightened and combined with the inner thread of the upper locking cap. The lower bottom surface of the upper locking cap 5 is in contact with the upper end surface of the upper locking sleeve 3, and the upper locking sleeve 3 holds the quartz rod 1 tightly.

[0020] The taper of the inner conical surface at the upper end of the support sleeve is equal to that of the inner conical surface at the lower end of the support sleeve.

[0021] A welding flange 7 is fixed on the outer circle of the lower locking cap 6 , and an oxygen-free copper gasket 8 is fixed on the inner circle position of the upper surface of the welding flange 7 .

[0022] The upper locking sleeve 3 and the lower locking sleeve 4 are both made of brass to ensure that the quartz rod 1 will not be crushed.

[0023] The sample delivery quartz rod locking device of the present invention is composed of a supporting sleeve 2, an upper locking sleeve 3, a lower locking sleeve 4, an upper locking cap 5 and a lower locking cap 6. The lower locking cap 6 is firmly welded to the CF50 welding flange 7. During installation, the quartz rod 1 is inserted into the locking device and the upper locking cap 5 and the lower locking cap 6 are tightened to press the upper locking sleeve 3 and the lower locking sleeve 4. Since the upper end of the supporting sleeve 2 and the upper locking sleeve 3 cooperate with the outer conical surface of the upper locking sleeve through the inner conical surface of the upper end of the supporting sleeve, and the lower end of the supporting sleeve 2 and the lower locking sleeve 4 cooperate with the inner conical surface of the lower end of the supporting sleeve and the outer conical surface of the lower locking sleeve, the inner diameters of the upper locking sleeve 3 and the lower locking sleeve 4 will shrink, and the quartz rod 1 will be clamped. The upper locking sleeve 3 and the lower locking sleeve 4 are made of brass to ensure that the quartz rod 1 will not be crushed. Due to the two upper and lower clamping positions, the quartz rod 1 and the CF50 welding flange 7 are ensured to be concentric and firm; then the locking device of the present invention is connected to the bellows of the equipment through the CF50 welding flange 7 to ensure that the quartz rod 1 and the bellows are concentric. The structure is simple and has the advantage of easy disassembly.
