Embodiment
To shown in Figure 6, a kind of handcart control wire plug latching device for switch cabinet of present embodiment 1 comprises the driving mechanism that prevents the blocking mechanism that control line plug 13 is pulled out and drive described blocking mechanism unlatching or locking from socket, wherein as Fig. 1
Described blocking mechanism comprises installing rack 1, rotating turret 3, and locking knee 5, and described installing rack 1 is installed on the cabinet; Described rotating turret 3 can be rotatably set on the described installing rack 1 by rotating shaft 2, and is subjected to a bias force that trends towards the primary importance of rotating turret; One end of described locking knee 5 is a free end, and the other end is a stiff end, and described locking knee 5 is installed on the described rotating turret 3 by described stiff end, and can rotate around described rotating shaft 2 with described rotating turret 3;
Described driving mechanism comprises push pedal 9 and interlock plate 8, and described push pedal 9 is subjected to a bias force that trends towards the primary importance of push pedal; Described interlock plate 8 has at least two groups, one end of each described interlock plate 8 is hinged in the described push pedal 9, and the other end of each described interlock plate 8 is hinged on the described cabinet, constitutes the parallel rod structure, in the jointed shaft rotating process, can keep described push pedal 9 parallel moving at described interlock plate 9;
A side of described push pedal 9 can with described rotating turret 3 on being connected with described locking knee 5 a relative end in contact and sliding; Described push pedal 9 is subjected to described handcart panel 10 towards an end of handcart panel 10 promotion moves to the second place of push pedal from the bias force of the primary importance of described push pedal, drives described rotating turret 3 turns to rotating turret from the primary importance of described rotating turret the second place thus; Described push pedal 9 breaks away from the promotion of described handcart panel 10 in the second place of described push pedal; When rotating turret 3 was in the second place of described rotating turret, the free end of described locking knee 5 was withheld on the connection handle 6 of the described control line plug 13 that is in blocking.
Wherein, the primary importance of rotating turret is a described rotating turret 3 when not promoted by described push pedal 9, is the position that nature is suspended on described installing rack 1; The second place of rotating turret is the promotion that described rotating turret 3 is subjected to described push pedal 9, turns to the position that the locking knee carries out locking to described control line plug 13; The bias force of rotating turret 3 can come from the gravity of described rotating turret 3 itself, also can be located at the spring force of the spring on the described rotating turret 3 from other.
The primary importance of push pedal is that described push pedal 9 is not promoted by described handcart panel 10, is nature and is suspended on position on the cabinet; The second place of push pedal is the promotion that described push pedal 9 is subjected to described handcart panel 10, around the extreme higher position that jointed shaft rotates; The bias force of push pedal 9 comes from the gravity of described push pedal.
In the present embodiment, described rotating turret 3 can be provided with first roller 4 with the end that described push pedal 9 contacts.The setting of described first roller 4 can reduce in the process that described push pedal 9 is promoted by handcart panel 10, friction between the contact jaw on described push pedal 9 and the described rotating turret 3, make described push pedal 9 can successfully promote the end that contacts with described push pedal 9 on the described rotating turret 3, thereby make described rotating turret 3 rotate 2 around described rotating shaft.Friction when just having begun to promote described push pedal 9 in order to reduce described handcart panel 10, convenient described handcart panel 10 is pushed to described push pedal 9 second place of push pedal from the bias force of the primary importance of described push pedal, the end that described push pedal 9 is promoted by described handcart is provided with second roller 11, and the cylindrical of described second roller 11 is concordant or protrude in described push pedal 9 and break away from and promote the side of back near described handcart panel 10.When described push pedal 9 is in the primary importance of described push pedal, the end face of described handcart panel 10 to described push pedal 9 break away from promote that the back is less than or equal to described push pedal 9 near the distance of a side of described handcart panel 10 with the movable distance of described rotating turret 3 towards described cabinet direction.Form on the relevant position of the side that described push pedal 9 contacts with described rotating turret 3 and be fit to the chute 12 that described first roller 4 rolls.The free end of described locking knee 5 is formed by the section of withholding and with the linkage section that turns round that the described section of withholding is connected on the described stiff end.For the free end that makes described locking knee 5 can be withheld reliably on the connection handle on the described control line plug 13, realize reliable locking, the described section of withholding is formed by two sections, one section is and the parallel parallel section of withholding in described control line plug 13 surfaces, another section is the section of withholding that tilts, the described parallel Duan Yiduan of withholding is connected with the described linkage section that turns round, and another section is connected with the described inclination section of withholding.Described installing rack 1 has two opposite side walls, and described rotating turret 3 can be rotatably set between the two opposite side walls of described installing rack 1 by described rotating shaft 2.
In other embodiments, comprise that also one is installed in the fixed head 7 on the described cabinet, each described interlock plate 8 is hinged with described cabinet, hinged between described interlock plate 8 and the described fixed head 7.Every group of described interlock plate 8 is a pair of, and each is arranged on the both sides of described push pedal 9 and described fixed head 7 accordingly to described interlock plate 8; Described installing rack 1 and described fixed head 7 all are arranged on the top of described cabinet, and described bias force is gravity.Described installing rack 1 and described fixed head 7 are molded on the parts of an one.
The course of work of handcart control wire plug latching device for switch cabinet of the present utility model:
Handcart is from testing the position when advance in the service position, handcart panel 10 on the handcart is by 11 pairs of push pedal 9 applied thrusts of second roller, make push pedal 9 move to the second place of push pedal by the primary importance of push pedal, because push pedal 9 is subjected to the restriction of interlock plate 8 and jointed shaft, can only reach upwards forward and be subjected to displacement stop motion after the displacement that makes progress is higher than handcart panel 10.Because first roller 4 on the rotating turret 3 contacts with push pedal 9, under the promotion of push pedal 9, first roller 4 moves up with push pedal 9, thereby make rotating turret 3 around the shaft 2 primary importances from rotating turret turn to the second place of rotating turret, locking knee 5 is rotated down with rotating turret 3 and arrives control line connector front side, withhold on the connection handle 6 of control line plug 13, the control line plug is carried out locking.At centre position and place, service position, because push pedal 9 is subjected to the power that handcart panel 10 applies always, make push pedal 9 not reset, thereby cause rotating turret 3 and be arranged on locking knee on the rotating turret 3 can not resetting and keeping locking, thereby realize reliable locking in centre position and place, service position.
Obviously, the foregoing description only is for example clearly is described, and is not the qualification to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all execution modes.And conspicuous variation of being extended out thus or change still are among the protection range of the utility model creation.
