Description
Technical field
The utility model relates to a kind of locking device.
Background technology
The safety locking mechanism of traditional metal drawing industry adopts the complex linkage of being with spring reset usually, and space hold is big, complicated operation, and cost an arm and a leg.
Summary of the invention
The purpose of this utility model is to provide locking device a kind of simple in structure, easy to operate.
In order to achieve the above object, the technical solution of the utility model is: a kind of locking device, comprise fixed block, first connecting rod, second connecting rod, snap close, the snap close support, pedal gear and frame, fixed block is fixedly connected on the frame, has first slotted hole on the first connecting rod, has the first slippage pin on the fixed block, the first slippage pin and the first slotted hole cunning are joined, second connecting rod and first connecting rod have the part inclined-plane and cooperatively interact, has second slotted hole on the second connecting rod, have the second slippage pin on the snap close, the second slippage pin and the second slotted hole cunning are joined, and the engagement of the tooth bar of the engaging tooth of snap close and snap close support, one end of pedal gear and first connecting rod load, and can make first connecting rod along the first slotted hole direction displacement, and having back-moving spring on the fixed block, back-moving spring and second connecting rod offset.
Described pedal gear comprises foot-driven lever, support bar and foot-operated spring, and the middle part and the support bar of foot-driven lever are hinged, and an end and first connecting rod are hinged, and the other end is foot-operated part, and an end of foot-operated spring is connected with support bar, and the other end is connected with first connecting rod.
Engaging tooth on the described snap close is a monocline face tooth, and the side of snap close support is a monocline face tooth bar, the monocline face tooth bar engagement of engaging tooth on the snap close and snap close support.
After adopting said structure, because first connecting rod and second connecting rod are that the part inclined-plane cooperatively interacts, as long as operating pedal mechanism, first connecting rod is moved up, drive second connecting rod and fail to agree skew, snap close is just thrown off with the snap close support, therefore simple in structure, and easy to operate.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the schematic diagram after the operating pedal mechanism among Fig. 1.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.
Referring to Fig. 1,2, shown in 3, a kind of locking device, comprise fixed block 1, first connecting rod 2, second connecting rod 3, snap close 4, snap close support 5, pedal gear 7 and frame 8, fixed block 1 is fixedly connected on the frame 8, has the first slotted hole 2-1 on the first connecting rod 2, has the first slippage pin 1-1 on the fixed block 1, the first slippage pin 1-1 and the first slotted hole 2-1 are sliding to be joined, second connecting rod 3 has the part inclined-plane with first connecting rod 2 and cooperatively interacts, has the second slotted hole 3-1 on the second connecting rod 3, have the second slippage pin 4-1 on the snap close 4, the second slippage pin 4-1 and the second slotted hole 3-1 are sliding to be joined, and the tooth bar 5-1 of the engaging tooth 4-2 of snap close 4 and snap close support 5 engagement, one end of pedal gear 7 and first connecting rod 2 loads, and can make first connecting rod 2 along the first slotted hole 2-1 direction displacement, and having back-moving spring 9 on the fixed block 1, back-moving spring 9 offsets with second connecting rod 3.
Shown in Fig. 1,2,3, in order to make pedal gear 7 can allow first connecting rod 2 vertically move, described pedal gear 7 comprises foot-driven lever 7-1, support bar 7-2 and foot-operated spring 7-3, the middle part of foot-driven lever 7-1 and support bar 7-2 are hinged, and an end and first connecting rod 2 are hinged, and the other end is foot-operated part, the end of foot-operated spring 7-3 is connected with support bar 7-2, and the other end is connected with first connecting rod 2.
Shown in Fig. 1,3, in order to play the locking effect, the engaging tooth 4-2 on the described snap close 4 is a monocline face tooth, and the side of snap close support 5 is monocline face tooth bar 5-1, the monocline face tooth bar 5-1 engagement of engaging tooth 4-2 on the snap close 4 and snap close support 5.
Referring to Fig. 1, shown in 3, when the utility model uses, depress foot-driven lever 7-1, first connecting rod 2 is moved up, because first connecting rod 2 and second connecting rod 3 are that the part inclined-plane cooperatively interacts, therefore first connecting rod 2 just drives second connecting rod 3 and is moved to the left, thereby the engaging tooth 4-2 that promotes snap close 4 breaks away from the tooth bar 5-1 of snap close support 5, and at this moment, snap close 5 can freely move up and down, when unclamping foot-driven lever 7-1, effect because of foot-operated spring 7-3 moves downward first connecting rod 2, and second connecting rod 3 is also because back-moving spring 9 resets simultaneously, and make snap close 4 recover locking, thereby snap close 4 can not be moved up and down.
