The utility model content
Technical problem to be solved in the utility model is the defective that overcomes prior art, a kind of anchor clamps of the installation seed crystal for the kyropoulos growing sapphire crystal are provided, the generation of abnormal conditions such as can avoid the molybdenum connecting rod bending or fracture, anchor clamps are not fragile, satisfy the demand of the side-play amount that produces during the seeded growth crystal.
For solving the problems of the technologies described above, the utility model provides a kind of anchor clamps of the installation seed crystal for the kyropoulos growing sapphire crystal, it is characterized in that,
The molybdenum joint and the molybdenum connecting rod that comprise movable connection;
Described molybdenum joint integral body is a hollow sleeve, and an end is connected with seed rod, and the inwall of the other end is arc, and matching with the molybdenum connecting rod is connected;
Have a termination that is the Rotary-table shape on the described molybdenum connecting rod, this side, termination is arc, cooperates with arc in the described molybdenum joint.
Described molybdenum joint one end has internal thread, is threaded with seed rod.
The space that arc in the described molybdenum joint constitutes can hold the termination activity therein of described molybdenum connecting rod.
The space that described molybdenum joint concave profile constitutes towards an end opening of internal thread greater than the opening towards the other end end face.
Described molybdenum connecting rod is one to have the straight-bar of described termination, and described termination global shape is Rotary-table, and the side surface of Rotary-table is arc.
The less end of described Rotary-table diameter is connected with described straight-bar.
Arc in the described molybdenum joint is the sphere of radius 8.5mm, and the arc of described molybdenum small end head side is the sphere of radius 8.0mm.
Arc in the described molybdenum joint is sphere, and described molybdenum small end head is sphere, and described molybdenum small end head is that sphere is not more than the spherical radius in the described molybdenum joint.
The less end of its opening of space that described molybdenum joint concave profile constitutes connects the passage of one section toroidal, and it is more big that passage more extends its opening to the other end end face.
The beneficial effect that the utility model reaches:
The anchor clamps of the installation seed crystal for the kyropoulos growing sapphire crystal of the present utility model, no longer adopt the hard connecting mode of screw-type between molybdenum joint and the molybdenum connecting rod, flexibly connect but adopt, the dependence arc contacts, but relative movement, the molybdenum connecting rod can have the revolution space in the certain limit, if certain skew is arranged during the seeded growth crystal, the molybdenum connecting rod can or not make molybdenum connecting rod bending even fracture thereupon being offset certain distance so, satisfy during the seeded growth crystal demand to side-play amount, anchor clamps are not fragile, saved production cost.

Fig. 2 is the molybdenum joint synoptic diagram among Fig. 1;
Fig. 3 is the molybdenum connecting rod synoptic diagram among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As Fig. 1, Fig. 2 and shown in Figure 3, the anchor clamps of the installation seed crystal for the kyropoulos growing sapphire crystal of the present utility model comprise molybdenum joint 1 and the molybdenum connecting rod 2 of movable connection, molybdenum joint 1 integral body is a hollow sleeve, one end, 11 inwalls have internal thread, can be threaded with seed rod, the inwall of the other end 12 is designed to arc 13, is connected for matching with molybdenum connecting rod 2.The space 14 that arc constitutes is bigger towards an end opening 141 of internal thread, and the space 14 that arc constitutes is less towards the opening 142 of the other end end face 121, make 2 assemblings of molybdenum connecting rod after, can snap in the space 14 that arc constitutes and not come off.
Preferable mode is the passage 15 that the less end of space 14 its openings that molybdenum joint concave profile constitutes connects one section toroidal, and it is more big that passage 15 more extends its openings to the other end end face 121, and being beneficial to can be movable within the specific limits after 2 assemblings of molybdenum connecting rod.
