Description

There is the American Unit Substation of hidden internal lock

Technical field

This utility model relates to American Unit Substation, particularly to the American Unit Substation with hidden internal lock.

Background technology

Tradition American Unit Substation only has a laminate, base plate is provided only with a through hole, cable leads to inside American Unit Substation by this through hole, the size of through hole is bad to be determined, when via design less, a small amount of cable can only be allowed to pass through, when the cable that user is actually used is more, cable is very thick, and this through hole cannot meet needs, it has to base plate is removed, readjust through hole, bothering very much, efficiency is low, poor universality, when clear size of opening is designed bigger time, but actually used cable is little, through hole is excessive is not suitable for the fixing of cable, less stable.Further, in order to prevent chamber door to be accidentally opened, chamber door is installed door lock.This protected mode has deficiency, as: protective capacities is poor, and lawless person is easy to picking lock and trespasses, destroys.

Utility model content

In order to solve above shortcomings in prior art, this utility model provides the American Unit Substation with hidden internal lock that a kind of versatility is good, protected effect is good.

For achieving the above object, this utility model is by the following technical solutions:

A kind of American Unit Substation with hidden internal lock, described American Unit Substation includes casing, chamber door and base plate；Described base plate includes:

First base plate, described first base plate is connected with casing, and described first base plate is provided with the first through hole；

Second base plate, described second base plate and the first base plate are connected, and described second base plate is provided with the second through hole, and the diameter of described second through hole is less than the diameter of described first through hole；

Described American Unit Substation farther includes:

Tumbler, described tumbler is arranged on casing, is arranged on the front side in described casing；One end of described tumbler is turning end；

Have contact with, described in have contact with and be arranged on described tumbler；

Fixture, described fixture is arranged on the rear side of described chamber door；Have contact with described in when described tumbler rotates forward and catch on fixture, when rotating backward, have contact with and unclamp described fixture.

According to above-mentioned American Unit Substation, it is preferable that for riveted joint between described first base plate and casing.

According to above-mentioned American Unit Substation, it is preferable that be bolted between described first base plate and the second base plate.

According to above-mentioned American Unit Substation, alternatively, described box body wall arranging through hole, described turning end is arranged on the inboard of described through hole.

Compared with prior art, this utility model has the beneficial effect that

1. arrange the first through hole and the second through hole small one and large one, it is suitable for different duties respectively, and the second base plate having the second through hole on it is less, it is arranged on the first base plate, easy accessibility, make base plate can be applicable to different duties, and simple to operation during conversion work state, improve the versatility of American Unit Substation；

2. have contact with and all adopt hidden with chamber door, can't see the lock structure of inside；And locking, unlatching are both needed to drive tumbler, it is necessary to use special frock to drive tumbler；Effectively prevent the illegal intrusion in the external world, improve protected effect.

Accompanying drawing explanation

With reference to accompanying drawing, disclosure of the present utility model will be easier to understand.Skilled addressee readily understands that: these accompanying drawings are used only for illustrating the technical solution of the utility model, and are not intended to protection domain of the present utility model is construed as limiting.In figure:

Fig. 1 is the basic block diagram of the American Unit Substation according to this utility model embodiment；

Fig. 2 is the basic block diagram of the hidden internal lock according to this utility model embodiment.

Detailed description of the invention

Fig. 1-2 and following description describe optional embodiment of the present utility model to instruct how those skilled in the art implement and reproduce this utility model.In order to instruct technical solutions of the utility model, simplify or eliminated some conventional aspects.Those skilled in the art should understand that the modification being derived from these embodiments or replacement will in scopes of the present utility model.Those skilled in the art should understand that following characteristics can combine to form multiple modification of the present utility model in every way.Thus, this utility model is not limited to following optional embodiment, and is only limited by claim and their equivalent.

Embodiment:

Fig. 1 schematically illustrates the structure chart of the American Unit Substation with hidden internal lock of this utility model embodiment, as it is shown in figure 1, described American Unit Substation includes:

Casing, chamber door；These parts are all the state of the art, do not repeat them here；

First base plate 1, rivets between described first base plate 1 and casing, and the first base plate 1 is provided with the first through hole；

Second base plate 2, is bolted to connection between the second base plate 2 and the first base plate 1, and the second base plate 2 is provided with the second through hole 6, and the second through hole 6 diameter is overlapping less than the diameter of the first through hole, the second through hole and the first throughhole portions.When cable is less when deployed, cable is relatively thin, and cable is through the first through hole and the second through hole, and what provide constraints is the second less through hole, and the second through hole can meet the demand of cable, cable also can play good restriction effect simultaneously.When the cable used is more, it is possible to unclamping bolt 3, pulled down by the second little base plate 2, allow cable pass through the first through hole, the first through hole had both met the demand that cable passes through, and also can cable be limited preferably.

Fig. 2 schematically illustrates the basic block diagram of the hidden internal lock of this utility model embodiment, as in figure 2 it is shown, described internal lock includes:
