Embodiment
Further specify below in conjunction with the scheme of accompanying drawing the utility model.
Shown in figure 10, withdrawable circuit breaker comprises drawout chassis 4, is installed in the breaker body 5 in the drawout chassis, and is shown in figure 11; The withdrawable circuit breaker adaptive device comprises keeper 1, support 2 and straight pin 3; Keeper 1 as shown in Figure 3, the upper and lower of keeper 1 are respectively equipped with keeper bolt hole 12,13, and the middle part of keeper 1 is provided with and is used for the semi-circular recesses 11 that cooperates with straight pin 3; As depicted in figs. 1 and 2; Two bolts pass two keeper bolts hole 12,13 respectively keeper 1 is fixed on the drawout chassis 4, and are as shown in Figure 4, and support 2 is fixed on the side of breaker body 5 through bolt 6; Extremely shown in Figure 8 like Fig. 5; Support 2 is L-shaped, is provided with a support bracket bolt hole 21 near the horizontal edge edge of L bracket 2, the corner of L bracket and be respectively equipped with the pin-and- hole 22,23 that is used to install straight pin 3 near the vertical edge edge of L bracket.
Wherein, breaker body 5 is provided with the mounting panel fixing hole, is provided with a nut in the mounting panel fixing hole, and bolt 6 passes support bracket bolt hole 21 and square nut to twisting, and support 2 is fixed on the breaker body 5.
The left side of withdrawable circuit breaker and right side are respectively equipped with the withdrawable circuit breaker adaptive device that matches; Support as shown in Figure 5 (straight pin 3 is arranged in pin-and-hole 22) and keeper shown in Figure 3 cooperate the right side of being located at withdrawable circuit breaker; Support shown in Figure 6 and keeper shown in Figure 3 cooperate the left side of being located at withdrawable circuit breaker; Left side and right side match, and carry out a kind of withdrawable circuit breaker adaptive of model.
In like manner; Cooperate the right side of being located at withdrawable circuit breaker behind support shown in Figure 7 and the keeper Rotate 180 degree shown in Figure 3; Cooperate the left side of being located at withdrawable circuit breaker behind support shown in Figure 8 and the keeper Rotate 180 degree shown in Figure 3; The supporting adaptive device of left and right sides like this can carry out withdrawable circuit breaker adaptive of another kind of model.
Among Fig. 5, straight pin 3 is in the pin-and-hole of being located near L shaped vertical edge edge 22, and is specifically as shown in Figure 9; After straight pin 3 passes pin-and-hole 22; Be stuck in the back side of support 2 with circlip 7, when using the connected mode of support shown in Figure 7 and straight pin, circlip shown in Figure 57 and straight pin 3 dismantled like need; Straight pin 3 is passed in the pin-and-hole 23 of support shown in Figure 52 corners, blocks with circlip 7 then and locate this straight pin 3.Each part straight pin, support and the interchangeable use of circlip, highly versatile.
