Embodiment
The present invention is described in further detail below in conjunction with drawings and the specific embodiments.
The divide-shut brake that accompanying drawing 1,2 is used for a kind of new switching equipment of the present invention breaks away from coupling, comprises main body 1, male 2, inner sliding sleeve 3, outer sliding sleeve 4; Described inner sliding sleeve 3 arranges in the cavity of main body 1; Described outer sliding sleeve 4 is arranged on the outside of main body 1; Be provided with outer spring 7 between described main body 1 and the outer sliding sleeve 4; Be provided with inner sliding sleeve support spring 5 between the bottom of described inner sliding sleeve 3 and main body 1; Described male 2 can be inserted in the inner sliding sleeve 3; The annular wall of described main body 1 is provided with through hole (not marking); Be provided with ball 6 in the described through hole; The excircle of described main body 1 is provided with projection (not marking); The excircle of described outer sliding sleeve 4 is provided with outer sliding sleeve projection 10; When the lower surface of described outer sliding sleeve projection 10 when projection on being arranged on main body 1 contacts, described ball 6 just snaps in the groove 11 on the outer sliding sleeve 4, as shown in Figure 1; The inwall of the cavity of described main body 1 is provided with interior jump ring 9; When inner sliding sleeve support spring 5 was in free state, deviate from the cavity of main body 1 to prevent inner sliding sleeve 3, as shown in Figure 1 the upper end that described interior jump ring 9 just blocks inner sliding sleeve 3; The circumference of the bottom of described male 1 is provided with male projection 12; When male projection 12 was hooked ball 6, described male 1 was by snap close; The top in the outside of described main body 1 is provided with outer jump ring 8; When male 1 during by snap close, described outer jump ring 8 just with the last end in contact of outer sliding sleeve 4; As shown in Figure 2.
During use, as shown in Figure 1, when male 2 was not inserted inner sliding sleeve 3, inner sliding sleeve support spring 5 was in free state, and deviate from the cavity of main body 1 to prevent inner sliding sleeve 3 upper end that described interior jump ring 9 just blocks inner sliding sleeve 3; At this moment, male 2 is inserted inner sliding sleeves 3 and continues compressing inner sliding sleeve support spring 5, when male projection 12 is hooked ball 6, described outer jump ring 8 just with the last end in contact of outer sliding sleeve 4, male 1 is by snap close, as shown in Figure 2 at this moment; At this moment, when outer sliding sleeve projection 10 is subjected to downward power, outer spring 7 by compression, outer sliding sleeve 4 can relative main body 1 move downward; Groove 11 on outer sliding sleeve 4 is seasonable with 6 pairs on ball, and ball 6 can be fallen in the groove 11, so male 1 breaks away from snap close, under the elastic force effect of inner sliding sleeve support spring 5, along with inner sliding sleeve 3 moves upward together; Inner sliding sleeve 3 resets to and interior jump ring 9 contact positions, if make this moment male 1 break away from inner sliding sleeve 3, can realize isolating.
Certainly main body 1 also can change thin-walled mechanism into instead, replaces ball to tie tight with spring, also can reach the purpose of dropout.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage:
