Description
Technical field
The present invention relates to a kind of system for aerial navigation on airport supplementary structure, particularly a kind of mechanical type navigational lighting aid load condition selector.
Background technology
System for aerial navigation on airport, is the important component part ensureing that airport security is run, ensures that its reliability service is safing top priority.The navigational lighting aid equipment that current airport is special, more than adopt the mode of traditional terminal block to control required different conditions.Although the mode in the external loop of this terminal block exists install simple advantage, its poor stability, failure rate is high, needs frequent dismounting in regular maintenance, often causes wiring to loosen, very easily produces potential faults; Simultaneously as there is earth fault in the loop, when needing investigation position of failure point, the demand of rapid build test point can not be met, and cannot fault loop be safeguarded in many equipment runs simultaneously, traditional wired plate due to its operating repairs loaded down with trivial details, the shortcomings such as efficiency is low, cannot meet the operation maintenance requirement on medium-and-large-sized airport.Therefore need now one can solution to the problems described above or device.
Summary of the invention
The present invention is the above-mentioned deficiency in order to solve existing for prior art, proposes a kind of structure simple, designs ingenious, easy switching, safe and reliable, and can avoid occurring loosening the mechanical type navigational lighting aid load condition selector with misoperation.
Technical solution of the present invention is: a kind of mechanical type navigational lighting aid load condition selector, comprise columnar base 1, one end of base 1 is provided with bonnet 2, the other end is opening, it is characterized in that: in the opening of base 1, activity is plugged with the upper cover 3 matched with base 1, the inwall of base 1 opening part is provided with at least two grooves 4, the outward flange at upper cover 3 top is provided with and the projection 5 that match identical with groove 4 quantity, handle 6 is also provided with on the top of upper cover 3, the bottom of upper cover 3 is provided with asessory shaft 7, the end of described asessory shaft 7 is through bonnet 2, and be also provided with guide vane end stop 8 in the end of asessory shaft 7, asessory shaft 7 between guide vane end stop 8 and bonnet 2 is socketed with back-moving spring 9, asessory shaft 7 between upper cover 3 and base 1 is socketed with buffer spring 10, multiple fixed contact 11 is provided with in base 1, and the moving contact 12 that match identical with fixed contact 11 quantity is then provided with in the bottom of upper cover 3.
The quantity of described groove 4 is four, and is circumferentially being uniformly distributed.
Compared with the existing technology, tool has the following advantages in the present invention:
The mechanical type navigational lighting aid load condition selector of this kind of version, its structure is simple, design ingenious, rationally distributed, the variety of problems that it in use leaks cruelly for traditional Wiring board type navigational lighting aid apparatus control system, design a kind of special selector structure, sound contact is all encapsulated in therein by it, in handoff procedure operating personnel can not with sound contact, fundamentally stopped the reasons such as misoperation and the potential safety hazard produced; The projection that its utilization simultaneously matches and groove define the position of condition selecting, and operating personnel are merely able to switch between several states set, thus the situation avoiding the causing trouble because of wiring error occurs.And its manufacture craft is simple, and cheap for manufacturing cost, therefore can say that it has possessed multiple advantage, be particularly suitable for applying in the art, its market prospects are very wide.
Accompanying drawing explanation
Fig. 1 is the vertical view of the embodiment of the present invention.
Fig. 2 is that A-A in Fig. 1 is to cutaway view.
Fig. 3 is the part exploded perspective view of the embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.As Fig. 1, Fig. 2, shown in Fig. 3: a kind of mechanical type navigational lighting aid load condition selector, comprise the columnar base 1 based on, bonnet 2 is provided with in one end of base 1, and the other end of base 1 is opening, in the opening of base 1, activity is plugged with the upper cover 3 matched with base 1, upper cover 3 can move in base 1 along the axis direction of base 1, on the inwall of the opening part of base 1, even circumferential is distributed with at least two grooves 4, the quantity of groove 4 is here preferably four, and the projection 5 that match identical with above-mentioned groove 4 quantity is then provided with in the outer edge at upper cover 3 top, the handle 6 for holding also is provided with on the top of upper cover 3, asessory shaft 7 is connected with in the bottom of upper cover 5, the end of this asessory shaft 7 is through bonnet 2, and be also provided with guide vane end stop 8 in the end of asessory shaft 7, asessory shaft 7 between described guide vane end stop 8 and bonnet 2 is socketed with back-moving spring 9, asessory shaft 7 between upper cover 3 and base 1 is then socketed with buffer spring 10, in base 1, be provided with multiple fixed contact 11, be then provided with moving contact 12 that is identical with described fixed contact 11 quantity and that mutually mate in the bottom of upper cover 3.
The course of work of the mechanical type navigational lighting aid load condition selector of the embodiment of the present invention is as follows: under initial condition, under the effect of back-moving spring 9, upper cover 3 is fastened on the bottom in base 1, moving contact 12 on upper cover 3 contacts with the fixed contact 11 on base 1, and this load condition selector works in a first state;
When needing the state switching navigational lighting aid load, user outwards pulls upper cover 3 hold the axial direction of handle 6 along base 1, upper cover 3 is extracted out from the inner chamber of base 1, projection 5 on upper cover 3 is also extracted out thereupon from groove 4, back-moving spring 9 is compressed, and due to the existence of guide vane end stop 8, upper cover 3 cannot be separated with base 1 completely, after disengaging with groove 4 protruding 5, upper cover 3 has recovered the degree of freedom of rotating, now operator drives upper cover 3 to turn an angle by handle 6, turn to protruding 5 corresponding with the groove 4 of next position after, again upper cover 3 is sent back in base 1, until all projections 5 are fallen in groove 4 again, in the process of upper cover 3 return, back-moving spring 9 can provide towards the strength bottom base 1 for upper cover 3, buffer spring 10 then can prevent the collision between upper cover 3 and base 1, both protections can not be damaged because mutually colliding, and there occurs change due to the relative angle between upper cover 3 and base 1, therefore multiple moving contact 12 also can contact with different fixed contacts 11 again respectively, namely allows this load condition selector be switched to the second state, and works in the second condition,
When needing to be switched to the third state, the 4th state, only need repetition above-mentioned steps; This device can realize the switching of various lines connected state, designer can be as required, select the quantity of groove 4 and protruding 5 matched, design quantity and the position of fixed contact 11 and moving contact 12, possess to allow this device the effect can carrying out handoff-security under multiple different channel status.
The mechanical type navigational lighting aid load condition selector of the embodiment of the present invention is provided with altogether 4 states, i.e. off state, conducting state, short-circuit condition and ground state, when upper cover 3 is extracted out relative to base 1, and keep moving contact 12 and the discontiguous state of fixed contact 11, be off state; And operating personnel can pass through rotary upper cover 3, the mode that the relative angle between itself and base 1 is changed realizes the object switched under above-mentioned three kinds of states (conducting state, short-circuit condition and ground state).
