Abstract
The utility model discloses a single crystal furnace turning plate limiting device which comprises a positioning plate arranged on a valve body, and a rocking arm, wherein a positioning gap is formed on the positioning plate; a rocking handle is arranged at one end of the rocking arm; the other end of the rocking arm and a turning plate connecting shaft are fixed; a spring is arranged on the rocking handle; a positioning table is arranged on the rocking arm and is used for positioning a mounting position of the spring; a positioning nut is arranged at one end, close to a positioning gap, of the rocking handle and is used for fixing the position of the spring; a first concave table and a second concave table are arranged at one end, away from the positioning gap, of the rocking handle; and a convex table matched with the first concave table and the second concave table which are arranged on the rocking handle is arranged on the rocking arm. The rocking handle and the rocking arm are pulled and rotated by a single hand only, the spring of the rocking handle can be compressed or restored by positioning so as to realize positioning or separating; and moreover, by utilizing the device, the position of the turning plate can be fixed after the turning plate is opened, the turning plate is prevented from being closed during operation of a single crystal furnace, and the device is simple in mechanism, convenient to operate and safe and reliable to limit.
Description
Technical field
The utility model relates to a kind of stop means, is specifically related to a kind of single crystal growing furnace turnover panel stop means.
Background technology
The czochralski silicon monocrystal furnace cavity is divided into two parts up and down, and the centre separates with flap valve.In the crystal pulling process, flap valve is opened always, and cavity is together with being one up and down; As run into special status, and can institute's crystal pulling be risen in the upper cavity, turnover panel is closed; Separate cavity up and down, from upper cavity, take out institute's crystal pulling, the thermal field heating region of lower chamber also is in high temperature material state; After the ready work, can open flap valve and continue crystal pulling.
In the crystal pulling process, as when special status not occurring and need close flap valve, turnover panel must be in open mode always; Present Straight pull circular valve structure single crystal growing furnace; Do not stop the space after turnover panel is opened,, run into crystal bar and can cause serious quality accident if turnover panel does not fix and rotates; Even security incident can take place, therefore increase a safe and reliable turnover panel stop means and be very important.Some single crystal growing furnace turnover panel position limiting structure is just installed a screw on the turnover panel handle, the valve shaft end face increases screw hole, when turnover panel is in open mode; Manually be selected into the screw retention turnover panel; This structure operation is complicated, needs two people to cooperate completion, if the screw screw-in depth is not enough; Might cause the turnover panel locate failure, the generation accident.
Summary of the invention
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of the utility model is to provide a kind of single crystal growing furnace turnover panel stop means, and this device fixing turnover panel position after turnover panel is opened prevents that turnover panel from closing in single crystal growing furnace work.
For achieving the above object, the utility model adopts following technical scheme:
A kind of single crystal growing furnace turnover panel stop means comprises the strongback 1 that is installed on the valve body 11, and location gap 2 is arranged on the strongback 1; Also comprise the arm 4 of shaking the hand; Crank handle 3 is installed in an end of the arm 4 of shaking the hand, and the other end of the arm 4 of shaking the hand and turnover panel coupling shaft 12 are fixing, and spring 5 is installed on crank handle 3; The arm 4 of shaking the hand is provided with positioning table 10; Positioning table 10 is used for the installation site of retainer spring 5, near an end of locating gap 2 setscrew nut 6 is housed also at crank handle 3, and setscrew nut 6 is used for fixing the position of spring 5; End away from location gap 2 on the crank handle 3 is provided with first concave station 8 and second concave station 9, the arm 4 of shaking the hand be provided with crank handle 3 on the boss 7 that matches of first concave station 8 and second concave station 9.
The utility model is only through one hand pulling and the rotation crank handle 3 and the arm 4 of shaking the hand; Can locate 5 compressions of the spring that makes on the crank handle 3 or recover, realize the location or throw off, this device can be after turnover panel be opened fixing turnover panel position; Prevent that turnover panel from closing in single crystal growing furnace work; Mechanism is succinct, and is easy to operate, and spacing safe and reliable.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in more detail.
As shown in Figure 1; A kind of single crystal growing furnace turnover panel of the utility model stop means comprises the strongback 1 that is installed on the valve body 11, and location gap 2 is arranged on the strongback 1; Also comprise the arm 4 of shaking the hand; Crank handle 3 is installed in an end of the arm 4 of shaking the hand, and the other end of the arm 4 of shaking the hand and turnover panel coupling shaft 12 are fixing, and turnover panel coupling shaft 12 is fixing with turnover panel 13.
As shown in Figures 2 and 3; The other end and the turnover panel coupling shaft 12 of arm 4 of shaking the hand is fixing; Spring 5 is installed on crank handle 3, and the arm 4 of shaking the hand is provided with positioning table 10, is used for the installation site of retainer spring 5; Near an end of locating gap 2 setscrew nut 6 is housed at crank handle 3, is used for fixing the position of spring 5.End away from location gap 2 on the crank handle 3 is provided with concave station 8 and concave station 9, the arm 4 of shaking the hand be provided with crank handle 3 on the boss 7 that matches of concave station 8 and concave station 9.
The principle of work of the utility model is:
Clockwise rotate the arm 4 of shaking the hand to Fig. 1 position, rotate crank handle 3 again, as shown in Figure 2; Make boss 7 snap in concave station 8, spring 5 resets, and setscrew nut 6 snaps in the gap 2 of location; Rotate counterclockwise arm 2 certain angles of shaking the hand; Setscrew nut 6 is snapped in the gap 2 fully, and the arm 4 of shaking the hand is fixed, and drives the stationkeeping of turnover panel coupling shaft 12 and turnover panel 13.
Clockwise rotate arm 4 certain angles of shaking the hand, as shown in Figure 3, make setscrew nut 6 throw off location gap 2; Pulling crank handle 3, spring 5 is compressed, and setscrew nut 6 is deviate from gap 2 fully; The boss 7 of shaking the hand on the arm 4 is deviate from concave station 8, rotates crank handle 3, makes boss 7 snap in concave station 9; Rotate counterclockwise the arm 4 of shaking the hand, drive turnover panel coupling shaft 12, drive turnover panel 13 simultaneously and turn to the position that to close.
