Fig. 7 is the utility model structural representation of the dustproof navigation system of switch in an embodiment.
As shown in Figure 7, the dustproof navigation system of switch is upper and lower axially symmetric structure, and the first half of axle is set forth, and the latter half structure is identical, no longer elaborates.
When positioning splicing face 27 splices with spacing Mosaic face 28, protection walls 3 embeds in protective troughs 53, and splicing boss 55a and 55b embed in splicing groove 5a and 5b, and connection boss 56a and 56b embed in connecting through hole 6a and 6b.And the first half of slide block 24 embeds in the limit sliding chutes 56a of spacing pedestal 18.
The utility model in an embodiment operation principle of the dustproof navigation system of switch is as follows:
When rotating shaft 25 is rotated, rotating shaft 25 drives ratchet 22 left or turns right.Under effect due to spring 21 pressure, when ratchet 22 rotates, slide block 24 applies downward power to roller 23, and the arc end of roller 23 is contacted with the curved surface of ratchet 23 all the time.
Because spring 21 is exerted pressure to slide block 24 all the time, so whenever ratchet 22 turns over 45 °, the toothed recess of roller 23 in ratchet 22, just can complete one-time positioning process.If need to again change the angle of ratchet 22, must be rotated by rotating shaft, apply revolving force.
When working in compared with overall situation at sand and dust or the operating time is long, if there is no anti-dust measure, Miniature universal change over switch is just easily out of order.If the curved surface of ratchet 22 is stained with sand and dust, can increase the contact friction of 24 of ratchet 22, roller 23 and slide blocks, increase the rotational resistance of ratchet 22, even can cause ratchet 22, roller 23 and slide block 24 mutually stuck, the phenomenon that cannot rotate, thus make switch failure.
The effect of embodiment and effect
The dustproof navigation system of switch providing according to the present embodiment, because the dustproof navigation system of switch is comprised of positioning pedestal and the splicing of spacing pedestal, during splicing, on positioning pedestal and spacing pedestal, arrange protection walls embed protective trough, splicing boss embeds splicing groove, connect boss and embed connecting hole, formed barrier one, stop sand and dust to enter the dustproof navigation system of switch inside, so, the dustproof navigation system of this switch has anti-dust effect, without the exterior protection system outside plus, just can prevent that sand and dust from entering in navigation system, avoid increasing ratchet, contact friction between roller and slide block, even can cause ratchet, roller and slide block are mutually stuck, the phenomenon that cannot rotate, thereby make switch failure, switch is increased considerably at sand and dust larger regional useful life, effectively in expansion environment for use, do not increasing installing space, being convenient to control appliance develops to miniaturization integrated direction.
