Description
Technical field
The utility model belongs to travel switch technical field, is related to lifesaving positioning device, and in particular to a kind of lifesaving positioning
If the waterproof position limit switch of spare tape safety plug.
Background technology
In technical fields such as lifesaving positioning, the triggering of disembarking for the equipment that can disembark generally requires travel switch to realize equipment
Automatic turn-on function.Generally, realize that the travel switch of equipment open and close controlling generally requires the influence for evading machine tool vibration, thus it is existing
Have in design more using the structure design of closure, install and maintenance process and its complicated and very long, the time-consuming consumption from tearing open to the process of repairing
Needs are installed again after the completion of power, and maintenance to readjust, the time cost and human cost of maintenance and fabrication are lengthened significantly；Together
When, because China gradually deploys to develop and use to water environment, the equipment used in lifesaving positioning field is accomplished by keeping up with anti-
Water is designed, but it is domestic at present without discovery can steady operation under water environment travel switch.

Limited block (16), gear in described switch pointer (5) side can freely detach inserting in described switch pointer (5) opposite side
The spacer pin (17) of safety plug (6) and gear in a groove of the cam (1)；
The trigger switch part, including bearing (7), be installed in being symmetrical between bearing (7) and shaft seating (3)
Two axles (8) of heart section, the bushing (10) for being enclosed on each axle (8) periphery, it is in tandem on the outside of the bushing (10) two
Individual microswitch (9), the reed (11) for being laterally connected in two microswitch (9) free ends and it is inserted into the shaft seating
(3) pin (12) of the vertical direction on；
The water-proofing treatment part, including it is flush-mounted in first O-shaped rubber seal of the rotating shaft (15) between housing bushing
(4) are enclosed, the rotating shaft (15) is sleeved on away from cam (1) side and is close to the back-up ring on the outside of casing (14) and is flush-mounted in institute
State at least 2 circle second O-shaped rubber seal (13) of the shaft seating (3) between box inside.
Further, the second O-shaped rubber seal (13) is 2 or 3 circles.
By applying technology contents of the present utility model, in off working state, switch pointer (5) is limited block (16) card
Extremely, it is ensured that rotating shaft (15) does not produce rotation；In working condition, the utility model departs from after mounting bracket, limited block (16) and limit
Position pin (17) departs from, and the rotation for now switching pointer (5) is no longer influenced by limitation, and rotating shaft (15) can be under the pretightning force of torsion spring (2)
Produce rotation, band moving cam (1) rotation, so as to stir the reed (11) for being close to cam (1) so that reed (11) is connected
Distance changes between two microswitches (9), so as to produce the electric signal of startup, completes the work of travel switch.
And in maintenance process, safety plug (6) is plugged, so that stuck switch pointer (5), such equipment is installed and repaired
Operation in journey would not trigger travel switch, while also ensureing that the maloperation being likely to occur in maintenance process is not interfered with
Travel switch, now limited block (16) and spacer pin (17) depart from.After maintenance terminates, pulling out safety plug (6) can just recover
The normal of travel switch is used.
In water environment working condition, cabinet is box house and outside unique gap with rotating shaft (15), is now passed through
Ring-shaped rubber sealing ring (4), back-up ring (14) and the triple waterproof measures of ring-shaped rubber sealing ring (13) prevent water from flowing into box house.
Compared with prior art, the utility model replaces traditional compression spring using torsion spring, can be after long-term close
Keep reliable open function；Alignment pin can be used simultaneously to limit the motion of switch pointer, so that in dismounting maintenance process
Middle guarantee travel switch is not triggered, with stronger safety；The first O-shaped rubber seal has been used to the junction of axle simultaneously
Enclosing (4), back-up ring (14) and the second O-shaped triple waterproof measures of rubber seal (13) prevents water from flowing into box house, it is ensured that electricity
Sub- equipment under water environment can normal work, filled up the technological gap of current this area.
