Abstract
The present invention relates to trolley switch cabinet static contact baffle locking device, it has telescopic head, telescopic head curls inward has telescopic band, the two ends of telescopic band are respectively connected with a locking fixture, described locking fixture is made up of lower baffle plate deadlock lever, connecting rod and overhead gage deadlock lever, is connected between lower baffle plate deadlock lever with overhead gage deadlock lever by connecting rod.Trolley switch cabinet static contact baffle locking device of the present invention is owing to having telescopic head, telescopic head curls inward has telescopic band, the two ends of telescopic band are respectively connected with a locking fixture, locking fixture inserts difference locking Barrow type switchgear upper and lower static contact baffles in upper and lower baffle plate obturator hernia, effectively prevent from trolley switch cabinet static contact baffle from being opened by mistake to open, avoid electric shock accidents to occur.Structure is simple, convenient operation, locking are firm, guarantees the complete of operation field safety measure.
Description
Technical field
The present invention relates to locking device, time especially for Barrow type switchgear upkeep operation, static contact baffles is easily opened by mistake the problem opened and the trolley switch cabinet static contact baffle locking device developed.
Background technology
At present; known trolley switch cabinet static contact baffle is the turnover automatic shutter along with car switch handcart, and without any problem during normal running, when upkeep operation, trolley switch cabinet static contact baffle is easy to be opened by mistake open; because this reason, often personal injury can be there is.On-the-spot urgent need can the specific purpose tool of firmly locking trolley switch cabinet static contact baffle.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art and the trolley switch cabinet static contact baffle locking device that can prevent from static contact baffles from opening by mistake opening providing a kind of structure simple, easy and simple to handle, safe and reliable.
In order to realize object of the present invention, the technical solution adopted in the present invention is:
Trolley switch cabinet static contact baffle locking device, there is telescopic head, telescopic head curls inward has telescopic band, the two ends of telescopic band are respectively connected with a locking fixture, described locking fixture is made up of lower baffle plate deadlock lever, connecting rod and overhead gage deadlock lever, is connected between lower baffle plate deadlock lever with overhead gage deadlock lever by connecting rod.
Described overhead gage deadlock lever entirety is in yi word pattern.
The described U-shaped of lower baffle plate deadlock lever entirety in side.
Described lower baffle plate deadlock lever entirety is the semi-circular of side.
The beneficial effect that the present invention has is:
Trolley switch cabinet static contact baffle locking device of the present invention is owing to having telescopic head, telescopic head curls inward has telescopic band, the two ends of telescopic band are respectively connected with a locking fixture, locking fixture inserts difference locking Barrow type switchgear upper and lower static contact baffles in upper and lower baffle plate obturator hernia, effectively prevent from trolley switch cabinet static contact baffle from being opened by mistake to open, avoid electric shock accidents to occur.Structure is simple, convenient operation, locking are firm, guarantees the complete of operation field safety measure.
Accompanying drawing explanation
The invention will be further described with embodiment by reference to the accompanying drawings:
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is the using state schematic diagram of the present invention shown in embodiment 1;
Fig. 3 is the using state schematic diagram of the present invention shown in embodiment 2.
In figure:, lower baffle plate deadlock lever 2, overhead gage deadlock lever 3, connecting rod 4, telescopic band 5, telescopic head 6, warning word 7, high pressure warning mark 8, lower baffle plate obturator hernia 9, overhead gage obturator hernia 10.
Embodiment
Embodiment 1:
As shown in Figure 1, trolley switch cabinet static contact baffle locking device of the present invention, there is telescopic head 6, telescopic head 6 curls inward has telescopic band 5, telescopic band is printed on warning word 7 and the high pressure alert icon 8 of " forbidding opening " " Keep Clear-High Voltage ", the two ends of telescopic band 5 are stretched out telescopic head and are also respectively connected with a locking fixture outward, described locking fixture is made up of with overhead gage deadlock lever 3 lower baffle plate deadlock lever 2, connecting rod 4, is connected between lower baffle plate deadlock lever 2 with overhead gage deadlock lever 3 by connecting rod 4.Described lower baffle plate deadlock lever 2 entirety is the U-shaped of side, and described overhead gage deadlock lever 3 entirety is yi word pattern.To utilize on fixed contact lower baffle plate original hole as lower baffle plate obturator hernia 9, utilize on fixed contact overhead gage that original hole is as overhead gage obturator hernia 10, the length of connecting rod 4 is identical with the spacing between lower baffle plate obturator hernia 9 and overhead gage obturator hernia 10.Described locking fixture is that the stainless steel bar being 3-5 millimeter by diameter makes, locking Barrow type switchgear upper and lower static contact baffles respectively, and time the present invention is no, telescopic band involves in telescopic head automatically, needs telescopic band to be pulled out when using.
Embodiment 2:
As shown in Figure 3, in the present embodiment, lower baffle plate deadlock lever 2 entirety is the semi-circular of side, and all the other are with embodiment 1.
Using method of the present invention is as follows:
As shown in Figure 2, first penetrated from lower baffle plate obturator hernia 9 by lower baffle plate deadlock lever 2, now locking fixture is in plumbness, and overhead gage deadlock lever 3 is taken advantage of a situation and penetrated in overhead gage obturator hernia 10.Complete lock operation.
Claims (1)
