Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment in the utility model can make up mutually.
Basic thought of the present utility model is: design a kind of locking mechanism, adopt the mode of ratchet, ratchet and elastomeric element or employing ratchet, two ratchets, switch is controlled the spanner locking.
Below in conjunction with accompanying drawing, each preferred embodiment of the present utility model is described further:
Embodiment one
With reference to Fig. 2 and Fig. 3, it shows structure and the use state of the locking mechanism of present embodiment respectively, this locking mechanism is used for the switch control spanner 4 that locking is positioned at the control cabinet outside, and this locking mechanism comprises: ratchet 1, ratchet 2, elastomeric element and switch control spanner 4.
Described ratchet 1 be fixed on the side plate 5 of described control cabinet and switch control spanner 4 between.One end of described ratchet 2 is connected in switch control spanner 4, the other end and 1 clamping of described ratchet.One end of described elastomeric element is connected on the described ratchet 2, and the other end is connected to described switch control spanner 4, and when described ratchet 2 was connected in described ratchet 1, described elastomeric element was used for fixing described ratchet 2.
As shown in Figure 2, in above-described embodiment, the end that described elastomeric element is connected in described ratchet 2 is positioned at: between centre position O and the second place A2; The other end that is connected in described switch control spanner 4 is positioned at: between centre position O and the 3rd position B1; Perhaps,
The end that described elastomeric element is connected in described ratchet 2 is positioned at: between centre position O and the primary importance A1; The other end that is connected in described switch control spanner 4 is positioned at: between centre position O and the 4th position B2.
For example, the end that described elastomeric element is connected in described ratchet 2 can be positioned at: between described ratchet 2 and described switch control spanner 4 junctions and described ratchet 2 and ratchet 1 access section, and the arbitrary position except the end points.The other end that described elastomeric element is connected in described switch control spanner 4 can be positioned at: between switch control spanner 4 and described ratchet 2 junctions to switch control spanner 4 and the control cabinet junction.
For example, with the be locked as example of development machine electric cabinet with the circuit breaker spanner, it can adopt above-mentioned action locking gear.Can operate requirement by the requirement of electric cabinet flame proof and electric cabinet outside, this mechanism is arranged on the outside of electric cabinet, namely by the jack shaft transition.The locking mechanism of present embodiment can lock closing of power circuit breaker or off-state, and the circuit breaker spanner remains on this latched position when being switched on or switched off, the vibration in the time of can not working because of development machine and cause the circuit breaker misoperation.
Wherein, as shown in Figure 3, the spanner hinge of ratchet 2 and circuit breaker is connected, and the two ends of elastomeric element are connected with ratchet 2, spanner 4 respectively, and ratchet 1 is fixed on the electric cabinet side plate 5.Electric cabinet internal breaker switch is connected with the electric cabinet external key by transition axis, rotates the break-make of control electric cabinet internal breaker by external key.Ratchet 1 is by being bolted on the electric cabinet side plate, and ratchet 2 one ends are connected on the circuit breaker spanner, and the other end and ratchet 1 cooperate, and are connected with elastomeric element in the middle of the ratchet 2, and the other end of elastomeric element is hinged on the spanner.When circuit breaker spanner during at on-position, by the pulling force effect of elastomeric element, ratchet 2 and ratchet 1 are pinned in this position, guarantee that circuit breaker reliably connects, guarantee when development machine work, avoid because vibrating or other external force causes the circuit breaker misoperation.When need switch circuit-breaker status, only need manual operation ratchet 2, ratchet 2 is separated with ratchet 1, rotating spanner just can easily be realized again.
As seen, the locking mechanism that present embodiment adopts ratchet 1, ratchet 2 and elastomeric element to form can realize the action locking to the circuit breaker spanner, and member production, assembling and dismounting in this locking mechanism is simple and reliable.
