The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the described a kind of access lock interlock of the utility model is further described.
To shown in Figure 4, the described a kind of access lock interlock of the utility model comprises that mainly interlocking sticks up piece 1, interlocking rod 2, interlocking ratchet 3, interlocking gear 4, pouring weight 6, limiting plate 7, limit switch 8, interlocks and stick up piece supporting seat 9 and interlocking ratchet supporting seat 10 like Fig. 1.
Wherein, the interlocking that is used for support fixation sticks up piece supporting seat 9 and is weldingly fixed on transmission case box plate 13 respectively with interlocking ratchet supporting seat 10, and interlocking sticks up piece supporting seat 9 and is positioned at interlocking ratchet supporting seat 10 tops.
Interlocking sticks up piece 1 and is connected interlocking and sticks up fixed axis one 14 places on the piece supporting seat 9, and interlocking sticks up piece 1 and can rotate around fixed axis 1.Interlocking sticks up the top placement pole 5 of piece 1, and pole 5 is connected on the travelling gear 12, and along with the rotation of travelling gear 12, pole 5 can be pushed down or leave interlocking and stick up piece 1.
The below that interlocking sticks up piece 1 connects pouring weight 6 through bolt, and pouring weight 6 is that interlocking sticks up the power that piece 1 rotates.The below that interlocking sticks up piece 1 also connects the upper end of interlocking rod 2 through bolt, interlocking rod 2 can stick up the rotation of piece 1 and moves up and down along with interlocking.
The lower end of interlocking rod 2 is through an end of connecting pin fixed connection interlocking ratchet 3, and the other end of interlocking ratchet 3 can block or leave interlocking gear 4.Simultaneously, this interlocking ratchet 3 also is connected on the fixed axis 2 15 on the interlocking ratchet supporting seat 10, and the moving up and down of interlocking rod 2 can drive interlocking ratchet 3 and rotate around fixed axis 2 15.Interlocking gear 4 is connected on the power transmission shaft 11, when the other end of interlocking ratchet 3 blocks interlocking gear 4, also is lockable with the power transmission shaft 11 that is connected of interlocking gear 4.
The lower end of interlocking rod 2 also is fixedly connected an end of limiting plate 7, and the other end of limiting plate 7 is positioned at limit switch 8 tops, and limit switch 8 is fixed on the transmission case casing; When limiting plate 7 moves down when touching limit switch 8 with interlocking rod 2, limiting plate 7 stops to move down, and makes that interlocking rod 2 also stops to move downward, and also stops to move downward thereby the interlocking ratchet that is fixedly connected with interlocking rod 23 sticks up piece 1 with interlocking.
Interlocking sticks up and also is provided with circular hole 16 on the piece 1, when circular hole 16 with after pole that it is complementary is connected, the feasible interlocking stuck up piece 1 and can not be rotated.
The use of the described a kind of access lock interlock of the utility model is following:
When access lock opened the door, operating personnel operated transmission case near-end door operation handwheel, rotated travelling gear 12, along with travelling gear 12 rotates; Pole 5 sticks up piece 1 with interlocking to be separated, and interlocking sticks up piece 1 under pouring weight 5 effects, rotates around fixed axis 1; Drive interlocking rod 2 and down move, interlocking rod 2 drives interlocking ratchet 3 and rotates around fixed axis 2 15, and interlocking ratchet 3 snaps in interlocking gear 4; Interlocking gear 4 is stuck, and power transmission shaft 11 can not be operated, and reaches the interlocking purpose.
Access lock at closing time, operating personnel operate transmission case near-end door operation handwheel, direction is opposite when opening the door; Along with travelling gear 12 rotates, pole 5 is pushed down interlocking and is stuck up piece 1, and interlocking sticks up piece 1 and rotates around fixed axis 1; Drive interlocking rod 2 and up move, interlocking rod 2 drives interlocking ratchet 3 and rotates around fixed axis 2 15, when pole 5 arrives assigned address; Interlocking ratchet 3 breaks away from interlocking gear 4, restPoses.
Under the particular case, remove interlocking if desired, can pack into and interlock and stick up the pole that circular hole 16 is complementary on the piece, making interlocking stick up piece 1 can not rotate, and can remove interlocking, satisfies instructions for use.
The described interlock of the utility model is applied to access lock; Can guarantee that the outside transmission case of access lock (or inner transmission case) only can be operated a handwheel under the normal condition; Assurance two fan hermatic doors can not be opened simultaneously, guarantee the integrality and the sealing of containment.Under specific circumstances, can remove interlocking, open two fan hermatic doors simultaneously, satisfy the use needs through measure.
