SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that above-mentioned prior art exists, provide an protection against insects type ammeter case, it can prevent effectively that toy such as worm from getting into the ammeter case and causing the damage to ammeter incasement part to ensure the normal use of ammeter case.

The utility model aims at realizing through the following technical scheme:

the utility model provides a protection against insects type ammeter case, includes the box, locates a plurality of entrance holes of box lower extreme, the entrance hole outside is equipped with protection against insects device, protection against insects device include the retainer plate, rotate connect in the rotatory cover in the retainer plate outside, locate the inboard expansion network of retainer plate, expansion network includes the dictyosome, locates the expansion joint at dictyosome middle part, locate be close to in the dictyosome the tightening wire of expansion joint one side, be equipped with the wire hole on the retainer plate, the tightening wire passes wire hole and fixed connection in rotatory cover is last.

The use principle is as follows: after the cable inserts the ammeter case, through rotating rotatory cover to the line is tightened up in the pulling, thereby makes the shrink of expansion network, and the flexible mouth of expansion network reduces to the tight cable of cover, and the space between cable and the entrance hole is covered by the expansion network completely almost, in order to prevent that the toy from getting into the ammeter case. When the cable needs to be accessed again or maintenance is carried out, the rotating cover can be rotated reversely to loosen the tightening wire, and then the telescopic opening of the telescopic net is manually enlarged so as to be convenient for relevant operation.

As the utility model discloses it is preferred, the retainer plate outside is equipped with spacing draw runner, rotatory cover inboard is equipped with spacing spout. The structure ensures the stability of the position between the rotating cover and the fixed ring and avoids the rotating cover from falling off accidentally.

As the utility model discloses it is preferred, the rotating housing outside is close to one side of box is equipped with the dog, be equipped with the cooperation on the box two stoppers of dog. The structure limits the rotation range of the rotating cover, on one hand, the tightening wire is prevented from being excessively pulled and damaged, on the other hand, the operation of a user is also simplified, and the tightening wire only needs to rotate back and forth within the range.

Preferably, the diameter of the fixing ring is larger than that of the wire inlet hole. The structure avoids the influence of the fixing ring on the normal operation of the access cable.

As the utility model discloses it is preferred, rotatory cover middle part is equipped with the round hole, the diameter of round hole is greater than the diameter in entrance hole. The structure avoids the influence of the rotating cover on the normal operation of the access cable.

As the utility model discloses it is preferred, be equipped with the polylith baffle in order to divide into a plurality of cavities with the box in the box, be equipped with the through wires hole on the baffle. The structure effectively avoids the mutual influence of a plurality of chambers.

As the utility model discloses it is preferred, the box surface is equipped with a plurality of correspondences the opening of cavity, it is a plurality of the opening part is equipped with observation window and access door respectively. The observation window is used for observing the working state of the electric meter, and the access door is convenient for replacing the incoming and outgoing line switch.

The utility model has the advantages that: effectively avoided the toy to get into and caused the damage to the ammeter case in the ammeter case to the normal work of ammeter case has been ensured.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The utility model provides a protection against insects type ammeter case, includes box 1, locates a plurality of entrance holes 2 of 1 lower extreme of box, the 2 outsides in entrance hole are equipped with protection against insects device, protection against insects device include the retainer plate, rotate connect in the rotatory cover 3 in the retainer plate outside, locate the inboard expansion network of retainer plate, expansion network includes the dictyosome 41, locates the expansion joint at dictyosome 41 middle part, locate be close to in the dictyosome 41 the tightening wire 42 of expansion joint one side, be equipped with the pin hole on the retainer plate, the tightening wire passes pin hole and fixed connection in rotatory cover 3 is last.

Specifically, the retainer plate outside is equipped with spacing draw runner, rotatory cover inboard is equipped with spacing spout. The structure ensures the stability of the position between the rotating cover and the fixed ring and avoids the rotating cover from falling off accidentally. And a stop block 5 is arranged on one side of the outer side of the rotating cover, which is close to the box body, and two limit blocks 6 matched with the stop block 5 are arranged on the box body. The structure limits the rotation range of the rotating cover, on one hand, the tightening wire is prevented from being excessively pulled and damaged, on the other hand, the operation of a user is also simplified, and the tightening wire only needs to rotate back and forth within the range.

In addition, the diameter of the fixing ring is larger than that of the wire inlet hole 2. The structure avoids the influence of the fixing ring on the normal operation of the access cable.
