Description

Novel mortice interlocking device
Technical field
The utility model belongs to electric switchgear assembly technical field, relates to interlocking device, particularly Novel mortice interlocking device.
Background technology
High-tension switch cabinet is the middle-end equipment of distribution system.It is used in the occasion that duty ratio is comparatively disperseed, loop is less; Load is nearby given the power distribution of a certain for upper level controller switching equipment circuit by handcart in cabinet.This grade of equipment reply load provides protection, monitoring and controlling.
In existing high tension distribution system, handcart can not arbitrarily movement.Because of space problem, so great majority are not provided with lock pin interlocking device, prevent handcart arbitrarily movement; And some are provided with interlocking device, its interlocking device is complicated, and the space taken is large, in limited space, be very difficult to install and maintenance, therefore, interlocking device in use, is often ignored by producer, will cause unnecessary potential safety hazard like this to operating personnel.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides a kind of easy to use, Novel mortice interlocking device of taking up an area the little and easy accessibility in space.
The purpose of this utility model is achieved through the following technical solutions: Novel mortice interlocking device, it comprises housing, an expansion link is axially interspersed with in described housing, be front with handcart toward the direction of service position movement, the front end of described expansion link is provided with a link plate, described expansion link is provided with a lug boss, the expansion link of lug boss front end is set with a back-moving spring, back-moving spring is positioned at housing, one rotating fanning strip is also installed in described housing, described fanning strip is hinged with a plate, the other end and the expansion link of connecting plate are hinged, described housing offers one and be convenient to the outstanding groove of fanning strip, the hull outside wall of groove side is provided with a lock pin, one end of lock pin is provided with a rotating lock pin handle and is provided with the spacer pin of a restriction lock pin handle inverse clock rotation.
Described lock pin handle offers a breach, and spacer pin is positioned at breach, and lock pin handle is also provided with a handle.
Described housing bottom is outstanding formation mounting panel to both sides, and mounting panel offers installing hole.
The utility model has the following advantages: lock pin interlocking device of the present utility model, by the interlock of expansion link, link plate, fanning strip and handcart, the rotation of lock pin handle is associated with the position of handcart, namely, during handcart work, rotary handle cannot rotate, and lock pin cannot plug, ensure that the safety of operating personnel, handcart is when experimental site, and rotary handle is rotatable, makes lock pin can plate; Be provided with back-moving spring, make fanning strip have reset function, thus make this device can realize under the action of the spring resetting; Lock pin, expansion link, fanning strip and back-moving spring, be installed on housing, and its structure is simple, easy accessibility, and in limited space, achieves this device, this device is taken up room little.

Embodiment
Be further described the utility model below in conjunction with accompanying drawing, protection range of the present utility model is not limited to the following stated:
As shown in Figure 1, Novel mortice interlocking device, it comprises housing 1, an expansion link 2 is axially interspersed with in described housing 1, be front with handcart toward the direction of service position movement, the front end of described expansion link 2 is provided with a link plate 3, when handcart moves toward service position, link plate 3 can block handcart, thus link plate 3 is moved forward together with handcart, described expansion link 2 is provided with a lug boss 4, the expansion link 2 of lug boss 4 front end is set with a back-moving spring 5, lug boss 4 blocks the rear end of back-moving spring 5, back-moving spring 5 is positioned at housing 1, the front end side wall of housing 1 blocks the front end of back-moving spring 5, thus when expansion link 1 is moved forward, back-moving spring 5 is compressed, one rotating fanning strip 6 is also installed in described housing 1, described fanning strip 6 is hinged with a plate 7, the other end and the expansion link 2 of connecting plate 7 are hinged, described housing 1 offers one and be convenient to the outstanding groove of fanning strip 6, when expansion link 2 moves forward, by hinged connecting plate 7, fanning strip 6 inverse clock is rotated, fanning strip 6 is made to give prominence to housing 1, housing 1 lateral wall of groove side is provided with a lock pin 8, one end of lock pin 8 is provided with a rotating lock pin handle 9 and is provided with the spacer pin 10 of a restriction lock pin handle 9 inverse clock rotation.
In the present embodiment, described lock pin handle 9 offers a breach 11, spacer pin 10 is positioned at breach 11, and lock pin handle 9 is also provided with a handle 12.
In the present embodiment, bottom described housing 1 to both sides outstanding formation mounting panel 13, mounting panel 13 offers installing hole.
The course of work of the present utility model is as follows: as shown in Fig. 1 ~ Fig. 4, handcart moves toward service position, handcart touches link plate 3, thus expansion link 2 is moved forward together along with handcart, now back-moving spring 5 is compressed, expansion link 2 moves forward, thus drive fanning strip 6 inverse clock to rotate, a part for fanning strip 6 gives prominence to groove, block the handle 12 of lock pin handle 9, lock pin handle 9 is turned clockwise, because lock pin 8 being provided with the spacer pin 10 that restriction lock pin handle 9 inverse clock rotates, thus lock pin handle 9 cannot be rotated, therefore lock pin 8 can not plug, ensure that operations staff's safety, handcart is from service position to after test position moves, and one time major loop disconnects, and link plate 3 unclamps, and drives fanning strip 6 to horizontal level by back-moving spring 5, and the fanning strip 6 blocking lock pin handle 9 separates completely, thus is extracted by lock pin 8.
