Abstract
The utility model discloses an earthed crank arm retaining clip mechanism for a vacuum load switch, which comprises an arc-shaped clamp splice and two block clamp plates of which the tail parts are connected with an earth plate of a combination switch. Connecting holes connected with an earth axis of the combination switch are formed by the head parts of the clamp plates and the clamp splice. One end of the arc-shaped clamp splice is provided with two grooves which are respectively clamped at the neck parts of the clamp plates. A clamping position clamped with the clamping end is arranged outside the other end of the arc-shaped clamp splice. Compressing parts for compressing by fastening bolts are arranged between the neck parts of the clamp plates and the clamp splice. Compared with a conventional design mode, the earthed crank arm retaining clip mechanism for the vacuum load switch has the characteristic of low manufacturing and transportation cost and also has the advantages that the earthed crank arm retaining clip mechanism is convenient to assemble and disassemble and is firm to connect.
Description
Technical field
The utility model relates to a kind of power system device, particularly relates to a kind of ground connection connecting lever geometrical clamp mechanism that is used for vacuum load switch.
Background technology
Present vacuum load switch divides three parts usually, comprises isolating switch part, vacuum lumen part and fuse and earthed switch part.As a kind of indoor AC vacuum on-load switch, be applicable to ring network power supply or terminal powered switch element in the distribution systems such as industrial and mineral, enterprise, residential quarters, school with high and low breaking capacity.
Because the ground plate on the ground connection connecting lever of earthed switch is had relatively high expectations with the compactness that is connected of earthed switch, its accuracy of manufacture requires also higher relatively.The ground connection connecting lever of traditional earthed switch is general direct integrated with earth's axis on-load switch, and incorporate design can guarantee that ground plate and earthed switch remain position relation accurately, yet its manufacture difficulty is higher, thereby cost is higher.This external ground connecting lever and earthed switch are the integrated design, and it is also relatively large taking of space, make that on-load switch expense in course of conveying is also higher.
Summary of the invention
For addressing the above problem, the utility model provides a kind of ground connection connecting lever geometrical clamp mechanism that is used for vacuum load switch, and this mechanism has the characteristics of easy accessibility.
The utility model solves the technical scheme that its technical problem adopted:
The ground connection connecting lever geometrical clamp mechanism that is used for vacuum load switch comprises arc fixture block and afterbody two clamping plate that are connected with the ground plate of on-load switch, and the head of said clamping plate forms the connecting hole that is connected with the earth's axis of on-load switch with said fixture block; One end of said fixture block is provided with the twice groove of the neck that clamps said clamping plate respectively, and the outside of the other end is provided with the screens that tightens each other with head, is provided with the part that presses through tightened bolt presses between the neck of said clamping plate and the fixture block.
The beneficial effect of the utility model: the utility model mainly comprises fixture block, two clamping plate and fastening bolt, and wherein fastening bolt is again a standard component, so entire mechanism is very convenient, with low cost on making; The utility model is again through being arranged at groove and the screens on the fixture block, add again bolt carry out firm, but therefore assurance mechanism is sturdy and durable when connecting; Again because of the utility model is easy to dismounting, thereby in the switch transportation, can effectively practice thrift the cost that transport point produces again earlier with its unloading.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the front view of the utility model;
Fig. 3 is the cutaway view of Fig. 2 section A-A;
Fig. 4 is that the utility model is assemblied in the structural representation that vacuum load switch is shut.
Embodiment
With reference to Fig. 1～Fig. 3; The ground connection connecting lever geometrical clamp mechanism that is used for vacuum load switch; It is characterized in that: comprise arc fixture block 1 and afterbody 21 two clamping plate 2 that are connected with the ground plate 6 of on-load switch, the head 23 of said clamping plate 2 forms the connecting hole 3 that is connected with the earth's axis 7 of on-load switch with said fixture block 1; One end of said fixture block 1 is provided with the twice groove 11 of the neck 22 that clamps said clamping plate 2 respectively, and the outside of the other end is provided with and head 23 screens 12 of chucking each other, is provided with between the neck 22 of said clamping plate 2 and the fixture block 1 through what fastening bolt 4 compressed to press part 5.
With reference to Fig. 4, installing and using of the utility model done further to introduce, Fig. 4 is assemblied in the structural representation that vacuum load switch is shut for the utility model.During installation earlier with arc fixture block 1 spiral-lock on the inboard of the earth's axis 7; Again two clamping plates 2 is installed in the earth's axis 7 outsides through groove on the arc fixture block 1 11 and screens 12; Then compress compressing member 5 through fastening bolt 4 again, the neck 22 of realization clamping plate 2 can closely be connected with the twice groove 11 on the arc fixture block 1; The final afterbody 21 that again ground plate 6 is connected in clamping plate 2 through bolt can be accomplished the installation of the utility model.
The utility model mainly comprises fixture block 1, two clamping plate 2 and fastening bolts 4, and wherein fastening bolt 4 is again a standard component, so entire mechanism is very convenient, with low cost on making; The utility model is again through being arranged at the groove 11 and screens 12 on the fixture block 1, add again fastening bolt 4 carry out fastening, but therefore assurance mechanism is sturdy and durable when connecting; Again because of the utility model is easy to dismounting, thereby in the switch transportation, can effectively practice thrift the cost that transport point produces again earlier with its unloading.
Certainly; The utility model is not limited to above-mentioned execution mode; Those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
