CN2252391Y - Transformer anti-prizing device - Google Patents

Abstract

The utility model relates to a transformer anti-prizing device, which makes the connection anti-prizing improvement between the box cover and the box edge of the transformer by a tapered threaded rod and a tapered screw cap; the utility model adopts the moving way to prevent being sawed, and the tapered threaded rod and the tapered screw cap are not easy to take off, which facilitates the theft protection. An E-shaped connection block 3 is inlaid on the box cover and the box edge of the transformer; a flat plate 9 inserted between the box cover and the box edge is provided with a hole 13 penetrated through by a threaded rod 6; the connected block 3 is caused to be arranged on the box cover 4 and the box edge 5 of the transformer by the threaded rod 6; matching clearances are arranged between the installed screw bolt, the hole 13 and the box edge 5 of the box cover 4; the threaded rod 6 and the screw cap 2 are caused to be free rotators; the cap body is a cone (round table) body so that although the lawbreaker uses the steel saw to saw the bolt body, due to the fact the bolt body is a rotator, so that the bolt body is not easy to saw off, which is favorable to the theft protection.

Description

The transformer anti-picking device

The utility model relates to the transformer anti-picking device.

Transformer is a power industry equipment, because some transformer yoke is located at the field, some lawless persons usually pry open transformer case lid recruitment tool, steal Inside coil, causes large areas to have a power failure, and the industry of this area and civilian electricity are affected.At present, take some measures on the transformer pick-proof, what have studs with conical screw and tapered cup nut on the case lid of transformer, must adopt the specialist tools mounting or dismounting, and general general tool can not unload.But because screw rod and nut are securing members, can not rotate between the two, the thief can utilize hacksaw sawed-off, so transformer is occurred repeatedly by the sled incident, it is hard to guard against to can be described as.

The purpose of this utility model is to avoid above-mentioned prior art weak point, and provides a kind of theftproof performance good, and the transformer anti-picking device under the difficult saw that can rotate when sawing with hacksaw helps the antitheft of transformer.

The purpose of this utility model enforcement is on four angles on the case lid of transformer and case edge, embed " mountain " font contiguous block, the middle flat board of contiguous block stretches between transformer case lid and the case edge, there is the groove that can inlay transformer case lid and case edge middle dull and stereotyped both sides, and on flat board, be shaped on the hole of being passed by screw rod, contiguous block is connected in the case lid of transformer and case along last by bolt, and the three is become one.On the flat board of both sides arcuate socket is arranged on the contiguous block, screw head and nut are sunken to wherein, in case bolt is sawed.Owing to have fit clearance to rotate between screw rod and the hole, again because nut is a bullet, when sawing with hacksaw, nut can rotate in the hole with screw rod, is difficult for by saw down like this, thereby can realizes that it is to move antitheft purpose.

The utility model can have following effect than above-mentioned prior art: because the same position on four angles on transformer case lid and case edge is inlaid with " mountain " font contiguous block transformer case lid and case edge are coupled together, and this contiguous block is connected in the case lid of transformer and case along last by bolt, little nut that exposes is awl (platform) body, and instrument can not unload.When the lawless person adopted hacksaw saw nut, nut rotated with screw rod, and nut is difficult for reaching with moving antitheft purpose by saw down.

Fig. 9, the 10th stops up 1 main complete section figure and the left view looked on Fig. 1 nut 2.

Below in conjunction with accompanying drawing will the utility model is described in further detail:

A kind of transformer anti-picking device that this utility model provided is on the basis of tapered cup nut and screw rod at existing two ends, improves.

The both sides of the flat board 9 of " mountain " font contiguous block 3 have makes dull and stereotyped 9 to stretch into transformer case lid 4 and case deep trench 7 and the shallow trench 8 between 5, the hole 13 that is passed freely through by screw rod 6 on dull and stereotyped 9; There are screw rod 6 and tapered cup nut 2 to be sunken to wherein also rotating arcuate socket 14 on the contiguous block 3 both sides flat boards.

The top of nut 2 has many prismatics hole 10 usefulness to stop up 1 tight closure, and the obstruction 1 of stifled back is a plane with the last plane of nut 2; Stopping up 1 has many ribs pit 12 down to cooperate with screw rod 6 top cylinders 11.

Claims (1)

1. a transformer anti-picking device is made up of tapered cup nut and conical screw, it is characterized in that:

A. the both sides of the flat board (9) of " mountain " font contiguous block (3) have and make flat board (9) stretch into transformer case lid (4) and case along deep trench (7) and shallow trench (8) between (5), the hole (13) that is passed freely through by screw rod (6) on dull and stereotyped (9); There are screw rod (6) and tapered cup nut (2) to be sunken to wherein also rotating arcuate socket (14) on the flat board of contiguous block (3) both sides;

B. there is many prismatics hole (10) on the top of nut (2) with stopping up (1) tight closure, and stifled back obstruction (1) is a plane with the last plane of nut (2); Stopping up (1) has many ribs pit (12) down to cooperate with screw rod (6) top cylinder (11).
