Abstract
The invention discloses an improved travel switch structure comprising a shell. Fixed contacts, a moving contact and left and right wire holders are arranged in the shell. One fixed contact is connected to the upper side of each wire holder. The moving contact is positioned between the two wire holders. One end of the moving contact is connected with a connecting rod outside the shell. A reset spring is arranged between the connecting rod and the shell. A rotating rod is movably connected to the connecting rod. A scale pan is arranged at one end of the rotating rod, and a wheel is arranged at the other end of the rotating rod. Through the structure, rotation of the moving contact can be realized only by addition or reduction of weights, manual pulling is not needed, time saving and labor saving are realized, and safety and convenience in use are achieved.
Description
Technical field
The present invention relates to field of switches, be specifically related to modified model travel switch structure.
Background technology
Travel switch is the one of position switch (also known as limit switch), is a kind of conventional small area analysis master control electrical apparatus.Utilize the collision of manufacturing machine moving component to make its contact action to realize to connect or disjunction control circuit, reach certain control object.Usually, this kind of switch is used to position or the stroke of limit mechanical motion, make that movable machinery stops automatically by certain position or stroke, counter motion, variable motion or back and forth movement etc. automatically.In electric control system, the effect of position switch is the detection realizing sequential control, positioning control and location status.For controlling stroke and the position limitation protection of plant equipment.The Direct Action Type shape journey switch of present use, main shock by mechanical movement realizes, if collision block translational speed is excessively slow, then contact just can not insantaneous break circuit, makes electric arc overstand on contact, is easy to burn out contact.If with manually pulling, easily there is corrosion phenomena after pulling piece Long-Time Service, move more difficult in the amplitude that wayward moving contact rotates.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, provide modified model travel switch structure, this structure only needs swing weight-adding can realize the rotation of moving contact, without the need to manually pulling, time saving and energy saving, safe and convenient to use.
For solving above-mentioned technical problem, the present invention is by the following technical solutions: modified model travel switch structure, comprise housing, enclosure interior arranges fixed contact, moving contact and left and right two and arranges junction block, all connect a fixed contact often arranging above junction block, moving contact is between two row's junction blocks, and moving contact one end is also connected with the connecting rod of outside, also arranges back-moving spring between connecting rod and housing; Connecting rod is also flexibly connected dwang, and dwang one end also arranges scale pan, and the other end arranges roller.When needs change-over circuit, in scale pan, put into suitable counterweight, utilize seesaw principle dwang to rotate, drive the connecting rod be connected with dwang to rotate, thus drive moving contact to rotate, thus the switching of realizing circuit.When not needing commutation circuit, then taken out by the counterweight in scale pan, back-moving spring reduces, and the connecting rod be connected is resetted with moving contact, the reduction of realizing circuit.This process saves the switching of manually moving realizing circuit, time saving and energy saving, also easily controls the rotation amplitude of moving contact, uses more convenient.Back-moving spring and counterweight with the use of, ensure that contact can realize insantaneous break and connecting circuit fast, make electric arc time of staying on contact be unlikely to long, protection contact intact.
Described case top vertical direction also arranges strutting piece, and strutting piece top is arcuate structure.When not needing commutation circuit, strutting piece can support dwang one end, avoids dwang oneself to rotate, touches other parts, cause potential safety hazard, use safer.
Described dwang can rotate around with connecting rod link.The quick switching of realizing circuit and reset.
Arranging platform with row's junction block is step arrangement.Be distributed in two positive and negative junction blocks on same row's cascaded surface of different height relatively far apart, contact is less likely to occur, and the chance be short-circuited reduces greatly.
Described back-moving spring one end is connected on the side of housing.
Compared with prior art, the invention has the beneficial effects as follows:
1, by arranging scale pan on dwang, only need swing weight-adding can realize the rotation of dwang, thus drive the connecting rod be connected with dwang to rotate, thus drive moving contact to realize position and move, reach the object of commutation circuit, this process realizes the change of moving contact position without the need to manual rotation, is easy to the amplitude controlling moving contact rotation, time saving and energy saving, easy to operate.
2, between connecting rod and housing, also back-moving spring is set; when not needing to carry out circuit switching, the reset of moving contact can be realized fast, thus ensure that contact can realize insantaneous break circuit fast; make electric arc time of staying on contact be unlikely to long, protect the intact of contact.
3, case top vertical direction also arranges strutting piece, when not needing commutation circuit, strutting piece can support dwang one end, avoids dwang oneself to rotate, touches other parts, cause potential safety hazard, use safer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, Reference numeral is expressed as: 1, housing; 2, fixed contact; 3, moving contact; 4, scale pan; 5, back-moving spring; 6, dwang; 7, connecting rod; 8, junction block; 9, strutting piece.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further elaborated, and embodiments of the invention are not limited thereto.
Embodiment 1:
As shown in Figure 1, the present invention includes housing 1, housing 1 inside arranges fixed contact 2, moving contact 3 and left and right two and arranges junction block 8, all connect a fixed contact 2 often arranging above junction block 8, moving contact 3 is between two row's junction blocks 8, moving contact 3 one end is also connected with the connecting rod 7 of outside, also arranges back-moving spring 5 between connecting rod 7 and housing 1; Connecting rod 7 is also flexibly connected dwang 6, and dwang 6 one end also arranges scale pan 4, and the other end arranges roller.
When needs change-over circuit, in scale pan, put into suitable counterweight, utilize seesaw principle dwang to rotate, drive the connecting rod be connected with dwang to rotate, thus drive moving contact to rotate, thus the switching of realizing circuit.When not needing commutation circuit, then taken out by the counterweight in scale pan, back-moving spring reduces, and the connecting rod be connected is resetted with moving contact, the reduction of realizing circuit.This process saves the switching of manually moving realizing circuit, time saving and energy saving, also easily controls the rotation amplitude of moving contact, uses more convenient.Back-moving spring and counterweight with the use of, ensure that contact can realize insantaneous break and connecting circuit fast, make electric arc time of staying on contact be unlikely to long, protection contact intact.
Embodiment 2:
The present embodiment preferred concrete structure on the basis of above-described embodiment is as follows: direction also arranges strutting piece 9 to housing 1 plan vertical, and strutting piece 9 top is arcuate structure.When not needing commutation circuit, strutting piece can support dwang one end, avoids dwang oneself to rotate, touches other parts, cause potential safety hazard, use safer.
