Fig. 2 is the vertical view after high voltage test wiring automatic retraction device removes cap.
Fig. 3 is the partial structurtes enlarged drawing of ratchet wheel pawl type stop.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As Fig. 1, a kind of high voltage test wiring automatic retraction device shown in Fig. 2, comprise: cap 1, housing 2, hollow shaft 3, contact rod 4, insulating support 5, instrument wire spool 6, equipment wire spool 7, separation sleeve 15, test connection 8, disc spring 9, brush 10, conduction rack 11, stop 12, instrument joint 13 and device junction 14, described housing 2 is hollow cylinders, this hollow cylinder is axis with hollow shaft 3 and has upper and lower two chambers, a contact rod 4 is provided with vertically by insulating support 5 in hollow shaft 3, instrument wire spool 6 and equipment wire spool 7 are enclosed within hollow shaft 3 through centre bore and lay respectively in two chambers up and down of housing.
Instrument wire spool 6 and equipment wire spool 7 are respectively equipped with separation sleeve 15, instrument wire spool and equipment wire spool are divided into inner chamber and exocoel by separation sleeve 15, instrument wire spool separation sleeve outer wall is wound with test connection 8, the (see figure 2) that to be connected with instrument joint 13 is stretched out in one end of test connection from upper shell, the other end passes from the string holes separation sleeve, is connected through the brush 10 of conduction rack 11 with contact rod 4 upper end; Described equipment wire spool separation sleeve outer wall is wound with test connection 8, the (see figure 2) that to be connected with device junction 14 is stretched out in one end of test connection from lower house, and the other end passes from the string holes separation sleeve and is connected through the brush 10 of conduction rack 11 with contact rod 4 lower end.Test connection on this upper and lower two wire spools is communicated with by a contact rod, and link uses the design of brush sliding contact, the rotation between wire spool is independent of each other, greatly improves the convenience of folding and unfolding test connection.
Disc spring 9 is respectively equipped with in the inner chamber of instrument wire spool 6, equipment wire spool 7, disc spring centered by hollow shaft rotating disk around, one end of disc spring is fixed on hollow shaft 3, and the other end is fixed on the inwall of instrument wire spool 6/ equipment wire spool separation sleeve 15.Housing 2 is also provided with the ratchet wheel pawl type stop 12 of restriction instrument wire spool 6 or equipment wire spool 7 rotation, the ratchet of described stop is separation sleeve 15, ratchet and housing 2 are hinged and are provided with return spring as shown in Figure 2, and what separation sleeve outer wall was corresponding with ratchet is provided with prevention projective table type ratchet gear teeth b.Cap 1 and housing 2 match closing lid on two end faces up and down of cylindrical housings.
Use procedure of the present invention is as follows:
As Fig. 2, as shown in Figure 3, the part that ratchet wheel pawl type stop 12 is provided with limiting tooth a becomes ratchet, and ratchet and housing 2 are hinged and are provided with return spring; On the separation sleeve outer wall of instrument wire spool 6 and equipment wire spool 7, annular is dispersed with multiple prevention projective table type ratchet gear teeth b, and this design makes separation sleeve become a ratchet.When twitching test connection, the prevention projective table type ratchet gear teeth b under force on separation sleeve outer wall overcomes the stop of limiting tooth a, and wire spool rotates, and test connection 8 is drawn out of; Once cancel the effect of power, wire spool is immediately by locking under the effect stoping projective table type ratchet gear teeth b and limiting tooth a, and the length of test connection 7 is fixed, and is at this moment connected with equipment or instrument by test connection by joint, tests.After test, twitch test connection 8 fast, stop projective table type ratchet gear teeth b to be separated instantaneously with limiting tooth a, under the effect of disc spring 9, wire spool turns round, automatic drawing back wiring.The present invention is also provided with a bandage on housing 2, easily this device can be fixed on test apparatus or other need on fixing position.
