embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in Fig. 1, Fig. 2, this kind is for the apparatus for controlling of lifting of the promoted self-locking on boiling range tester, comprise heating plate 1, its unique distinction is: at heating plate, fix a ladder-shaped frame 2 for 1 time, at the small bore end of ladder-shaped frame 2, connect a rectangle back up pad 3; Described apparatus for controlling of lifting also comprises a base elevating mechanism forming after being connected by lifting shaft 4, rectangle hollow base 12, retaining block tongue 7, rising pusher dog 10, decline pusher dog 11, handle 8, hoistway 5 and shaft coupling 9.
Wherein, retaining block tongue 7 is rectangle, and central authorities have a rectangular mesopore 6, and the L shaped tail end of retaining block tongue 7 is fixed in the gap of block tongue control panel on rectangle hollow base 12, and the other end of retaining block tongue 7 is free-end; When free-end is downward, the both sides minor face of mesopore 6 just in time blocks two end faces of lifting shaft 4.
Between the bottom surface of hoistway 5 and the upper surface of retaining block tongue 7, be connected with spring, make mesopore 6 block all the time lifting shaft 4, retaining block tongue is metal stainless steel, and lifting shaft matches with hoistway, is double sided slider bar structure; Lifting shaft 4 from top to bottom, through the hoistway 5, the retaining block tongue 7 that are fixed on rectangle hollow base 12 central authorities, drops in the bottom slide track seat of rectangle hollow base 12.
Fig. 3,4,5 be respectively the A-A of Fig. 2 to sectional view, B-B to sectional view and C-C to sectional view.As shown in the figure, shaft coupling 9 is fixed on the sidewall of rectangle hollow base 12, and the interior connecting end of shaft coupling 9 connects respectively rising pusher dog 10 and decline pusher dog 11, the outer join end connecting handle 8 of shaft coupling 9; In the bottom of lifting shaft 4, be fixed with a shifting block 13; Rising pusher dog 10 touches mutually with shifting block 13 when handle 8 presses down, and when decline pusher dog 11 is lifted on handle 8, touches mutually with retaining block tongue 7; Rectangle back up pad 3 is fixed on the top of lifting shaft 4.
