Between, meanwhile, the locking degree of blocking device is poor, is easily deformed.
The content of the invention
The purpose of the present invention is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of Lock for switch cabinet locking apparatus.
To achieve the above object, the present invention uses following technical proposals：
A kind of Lock for switch cabinet locking apparatus, including the locking piece being arranged between cabinet door and secondary plug, locking piece are L-type knot
Structure, and the plane where locking piece is parallel with cabinet door, locking piece is arranged at secondary plug front portion, and described locking piece one end sets solid
Determine device, other end fixed setting pivot pin, the fixing device is fixed on cabinet inside top and fixing device be arranged at it is secondary
Directly over plug, the pivot pin is vertical with plane where locking piece, and pivot pin end set latch shaft, the latch shaft can stretch
Contract, the hole matched with latch shaft is set on cabinet, the fixing device is flexibly connected with locking piece.
Preferably, the fixing device includes fixture and connecting shaft, and the fixture is fixed on cabinet inside top, and
Fixture includes groove and is arranged at the fixed angles at groove both ends, and connecting shaft level is fixedly installed on inside grooves, and locking piece
One end is vertical with connecting shaft.
It is further preferred that the fixed angles set fixing hole, the fixation of fixture is realized by fixed fixing hole.
Preferably, locking piece is the L-type structure with certain radian, and angular region is [120,150] in L-type structure.
Preferably, latch shaft is solid cylinder structure, and latch shaft and the length sum of pivot pin are more than Secondary socket and cabinet
The distance of door.By above-mentioned setting, latch shaft can be stretched into freely in the hole of cabinet door, realize lock operation.
The beneficial effects of the invention are as follows：
1. the invention provides blocking device it is simple in construction, operation is easy, and blocking device small volume, is switch cubicle
Inside saves substantial amounts of inner space, reduces the space of whole switch cubicle；
2. blocking device locking degree provided by the invention is preferable, realize that locking acts on by the gravity principle of locking piece, it is real
It is now simple, it is workable, it is easy to spread；
3. blocking device provided by the invention does not make larger change to switch cabinet body, only set in cabinet door
Hole, and hole corresponding with fixing device is set in cabinet inside top, technique is easily realized.
Brief description of the drawings
Fig. 1 is Lock for switch cabinet locking apparatus front view provided by the invention；
Fig. 2 is Lock for switch cabinet locking apparatus top view provided by the invention；
Fig. 3 is Lock for switch cabinet locking apparatus left view provided by the invention；
Fig. 4 is that Lock for switch cabinet locking apparatus provided by the invention uses procedure structure schematic diagram；
Wherein 1. locking piece, 2. pivot pins, 3. latch shafts, 4. connecting shafts, 5. fixtures, 6. secondary plugs.
Embodiment
The present invention is further described with reference to the accompanying drawings and examples.
As shown in Figure 1 to Figure 3, a kind of Lock for switch cabinet locking apparatus, including the locking being arranged between cabinet door and secondary plug 6
Piece 1, locking piece 1 is L-type structure, and the plane where locking piece 1 is parallel with cabinet door, before locking piece 1 is arranged at secondary plug 6
Portion, described one end of locking piece 1 set fixing device, other end fixed setting pivot pin 2, and the fixing device is fixed on inside cabinet
Top and fixing device are arranged at directly over secondary plug 6, and the pivot pin 2 is vertical with the place plane of locking piece 1, and the end of pivot pin 2
Portion sets latch shaft 3, and the latch shaft 3 is scalable, the hole matched with latch shaft 3 is set on cabinet, the fixing device is with closing
Locking plate 1 is flexibly connected.
Preferably, the fixing device includes fixture 5 and connecting shaft 4, and the fixture 5, which is fixed on inside cabinet, to be pushed up
Portion, and fixture includes groove and is arranged at the fixed angles at groove both ends, the level of connecting shaft 4 is fixedly installed on inside grooves, and
The one end of locking piece 1 is vertical with connecting shaft 4.
It is further preferred that the fixed angles set fixing hole, the fixation of fixture is realized by fixed fixing hole.Due to
Sealed requirement of the blocking device for door of switch cabinet is higher, and this requires fixing device to realize good fixation, Cai Nengshi
Existing locking piece and the setting of Secondary socket relative position, therefore, setting some fixing holes in fixed angles, realize fixing device
It is effective fixed.
Preferably, locking piece 1 is the L-type structure with certain radian, and angular region is [120,150] in L-type structure.Close
Locking plate is L-type structure and bearing pin is vertical with plane where locking piece, if locking piece is arranged into acute angle, locking piece is according to itself
During gravity sag, sagging space is smaller, therefore, locking piece is arranged into obtuse angle, by the way that locking piece is arranged into obtuse angle, locking piece
Sagging space is larger, and beneficial to realizing blocking function, by being [120,150] by angular region in L-type structure, angle is held during locking
Easily hold.
Preferably, latch shaft 3 is solid cylinder structure, and latch shaft 3 and the length sum of pivot pin 2 are more than Secondary socket 6
With the distance of cabinet door.By above-mentioned setting, latch shaft 3 can be stretched into freely in the hole of cabinet door, realize lock operation.
The course of work is as follows：
When secondary plug 6 is not inserted in Secondary socket, locking piece 1 is by self gravitation effect, in naturally drooping state, by
It is arranged in fixing device directly over Secondary socket, and locking piece 1 is arranged at the front portion of secondary plug 6, then latch shaft 3 is extended to cabinet
In the hole of door, because latch shaft 3 is arranged at the end of pivot pin 2, latch shaft 3 is against on pivot pin 2, because the shelves of latch shaft 3 only act on,
Cabinet door can not normal switching-off；
When secondary plug 6 is inserted in Secondary socket, locking piece 1 receives the support of secondary plug 6, and locking piece 1 rises, locking
Piece 1 drives pivot pin 3 to move up, then latch shaft 3 can move freely under the passage of cabinet door, realize the normal switching-off of cabinet door.
Although above-mentioned the embodiment of the present invention is described with reference to accompanying drawing, model not is protected to the present invention
The limitation enclosed, one of ordinary skill in the art should be understood that on the basis of technical scheme those skilled in the art are not
Need to pay various modifications or deformation that creative work can make still within protection scope of the present invention.
