Also have, ring main unit top cover is exactly one flat plate, top cover is provided with a lot of through hole, cover plate directly contacts with ring network cabinet body, although the through hole on top cover meets the needs of heat radiation, but easily allows dust fall into inside ring main unit, thus the use of ring main unit is impacted, make ring main unit easily break down when working, add the maintenance cost of ring main unit, shorten the service life of ring main unit.

Utility model content

In order to solve above shortcomings in prior art, this utility model provides that a kind of protection effect is good, the ring main unit with internal lock of good heat dissipation effect.

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

A kind of ring main unit with internal lock, described ring main unit includes cabinet, cabinet door and top cover; Described internal lock includes:

Tumbler, described tumbler is arranged on the right side in ring main unit, and the front end of tumbler is fixed on the guidance panel of ring main unit;

Turning arm, described turning arm is fixed on described tumbler, has the first through hole;

Guide pipe, described guide pipe is arranged on rear side of described guidance panel;

Lock core, one end of described lock core is in described first through hole, and the other end is in described guide pipe;

Annular element, described annular element is arranged on described cabinet side behind the door, holds the lock core stretching out guide pipe;

Second through hole, described second through hole is arranged on described cabinet wall, and the turning end of described tumbler is arranged on the inboard of described second through hole;

Guard member, described guard member is arranged in the interlayer of cabinet wall, and upper end bends and stretches out outside described second through hole;

Elastomeric element, described elastomeric element one end is fixed on described cabinet wall, and the other end is fixed in described guard member.

Described top cover is provided with BAIYE hole.

According to the above-mentioned ring main unit with internal lock, it is preferable that described lock core is " L " shape.

According to the above-mentioned ring main unit with internal lock, alternatively, being provided with sleeve between described top cover and cabinet, bolt is fixed on described cabinet after described top cover, sleeve.

According to the above-mentioned ring main unit with internal lock, it is preferable that described bolt has 4, lay respectively on 4 angles of described top cover.

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

1. lock core, annular element all adopt hidden, 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;

2. original through hole being changed into BAIYE hole, the thermolysis in hole can be played, have again covering with the top of hole when, it is possible to prevent the entrance of dust, between top cover and cabinet, have sleeve, making generation gap between top cover and cabinet, thus reaching better radiating 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.

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 basic block diagram of the ring main unit with internal lock of this utility model embodiment 1, as it is shown in figure 1, described in there is the ring main unit of internal lock include:

Cabinet 5, Qianmen; These parts are all the state of the art, do not repeat them here;

Top cover 1, described top cover has BAIYE hole 2, and this BAIYE hole 2 sets covering above through hole, thus realizing existing opening for dispelling the heat, making again overthe openings set and covering in order to avoid dust enters, reaching dust-proof effect;

Being provided with sleeve 4 between top cover 1 and cabinet 5, bolt 3 is fixed on cabinet through top cover, sleeve. Bolt 3 has 4, lays respectively on 4 angles of top cover 1. Sleeve 4 makes generation gap between top cover 1 and cabinet 5, thus reaching better radiating effect.

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

Tumbler 11, described tumbler is arranged on the right side in ring main unit;

Turning arm 21, described turning arm is fixed on described tumbler, has the first through hole 22;

Guide pipe 41, described guide pipe is arranged on rear side of described guidance panel;

Lock core, lock core adopts " L " shape bonding jumper, and including the Part I 31 and the Part II 32 that are 90 degree of bendings, one end of described lock core is in described first through hole, and the other end is in described guide pipe;

Annular element 51, described annular element is arranged on cabinet side behind the door, holds the lock core stretching out guide pipe.

Fig. 3 schematically illustrates the basic block diagram of the guard member of this utility model embodiment, as shown in Figure 3, second through hole, described second through hole is arranged on the side of the turning end of the described tumbler 11 on rear side of described cabinet, cabinet is double-decker in the second through hole, is made up of outer wall 61, inwall 62;

Guard member 71, described protection setting is in interlayer, and upper end bending is extended outside interlayer;

Spring 81, one end of described spring is fixed in described guard member, and the other end is fixed on cabinet so that described second through hole closed by spring;

The work process of above-mentioned internal lock is:

Press described guard member, expose the second through hole, use frock to be also enclosed within described turning end through the second through hole, rotate forward tumbler, rotate thus arm is rotated, make lock core enter in described annular element, and then from internal locking cabinet door;

Unclamping described guard member, under spring drives, guard member closes described second through hole;

When internal unit safeguarded by needs, use frock to reversely rotate tumbler, thus band movable lock core departs from annular element, and then open cabinet door from inside.
