Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in fig. 1-7, a three-phase combined anti-theft structure for a high-low voltage chamber of a transformer comprises an operation chamber 1 and an oil tank chamber 2, wherein the operation chamber 1 is arranged on one side of the oil tank chamber 2, and a transformer is arranged in the oil tank chamber 2; a door leaf 11 and a lock body 12 are arranged on one side of the control room 1; the lock body 12 comprises a handle 121, a connecting plate 122, a bolt rod 123 and an anti-theft bolt 124; the handle 121 is arranged on the outer side of the door leaf 11, the connecting plate 122 is arranged on the inner side of the door leaf 11, and the handle 121 penetrates through the door leaf 11 and is connected with the connecting plate 122; the anti-theft bolt 124 is of a pentagonal structure; the anti-theft bolt 124 penetrates through the door leaf 11 from the outer side of the door leaf 11 to be connected with the connecting plate 122; the latch rod 123 is hinged to the connecting plate 122, and when the handle 121 drives the connecting plate 122 to rotate, the latch rod 123 moves up and down to be inserted into or separated from the lock hole 01 of the control chamber 1.

When the control chamber 1 needs to be locked, the door leaf 11 is closed, the handle 121 is rotated, the handle 121 drives the connecting plate 122 to rotate, the bolt rod 123 is driven to move upwards, the bolt rod 123 is inserted into the lock hole 01, the door leaf 11 is closed in place, then the anti-theft bolt 124 is tightened, and the connecting plate 122 and the door leaf 11 are fixed together by the anti-theft bolt 124 and cannot rotate, so that the anti-theft of the door leaf 11 is realized. Because the anti-theft bolt 124 is of a pentagonal structure, the anti-theft bolt cannot be unscrewed without using a turning tool, and if the anti-theft bolt is forcibly damaged by using violence, the locking of the anti-theft bolt 124 on the connecting plate 122 cannot be released even if the handle 121 is broken, so that the anti-theft bolt is safe and reliable. On the basis, an open lock can be further arranged to lock the handle 121, so that the anti-theft performance is further improved. The utility model discloses simple structure to lower cost has realized comparatively reliable theftproof performance, is fit for the needs based on economic level and social security condition in the central and south America area.

In a further description, the lock body 12 further includes a first sleeve 125, a second sleeve 126 and a bottom plate 127, the first sleeve 125 is disposed on the outer side of the door leaf 11, and the anti-theft bolt 124 passes through the first sleeve 125 and is connected to the connecting plate 122; the second sleeve 126 is connected to the connecting plate 122, the second sleeve 126 is in a C-shaped structure, and the gap of the second sleeve 126 faces the handle 121; the bottom of the second sleeve 126 is connected to the bottom plate 127, and the bottom plate 127 is connected to the connecting plate 122.

The first sleeve 125 protects the exterior of the anti-theft screw, and the anti-theft nut cannot be unscrewed by other tools without using a special internal pentagonal wrench, thereby increasing the safety. The second sleeve 126 is fixed to the bottom plate 127, and the second sleeve 126 is of a C-shaped structure, and the combination of the two is used for installing an open lock to lock the handle 121.

Further, the top and the bottom of the connecting plate 122 are respectively hinged with the latch rods 123, the inner side of the door leaf 11 is provided with the limiting sleeves 111, the two limiting sleeves 111 are respectively arranged at the upper and lower ends of the inner side of the door leaf 11, and the two limiting sleeves 111 are respectively sleeved at the outer sides of the two latch rods 123.

Two upper and lower spring bolt poles 123 are all fixed with the upper and lower both sides of door leaf 11, strengthen the theftproof performance, because two upper and lower spring bolt poles 123 all move under the drive of connecting plate 122, in order to guarantee that spring bolt pole 123 can break away from smoothly and insert lockhole 01, so set up stop collar 111, prevent that spring bolt pole 123 from rocking.

To explain further, a hand hole 02 sealing assembly 21 is arranged between the top of the control chamber 1 and the top of the oil tank chamber 2, the hand hole 02 sealing assembly 21 comprises a sealing plate 211 and a sealing cover 212, the sealing plate 211 is fixed with the top of the oil tank chamber 2, and the sealing cover 212 is fixed with the control chamber 1; a hand hole 02 is formed in the top of the oil tank chamber 2, the hand hole 02 is communicated with the inside of the oil tank chamber 2, and the hand hole 02 is sealed by the sealing plate 211; the sealing cover 212 completely snaps the sealing plate 211.

The hand hole 02 is a structure externally connected to the inside of the tank chamber 2, and thus theft prevention is also required. The hand hole 02 is first sealed and fixed by the sealing plate 211, which is the first level of theft prevention. The sealing plate 211 is then sealed and fixed using a sealing cover 212, which is a second level of theft protection. Therefore, the two protection facilities of the sealing cover 212 and the sealing plate 211 need to be broken when the hand hole 02 is opened from the outside, which is difficult, thereby enhancing the sealing performance of the hand hole 02.

In a further description, the sealing cover 212 is a square shell structure, one side of the sealing cover 212 close to the operation chamber 1 is fixed to the operation chamber 1 by a bolt, and the bolt is disposed inside the operation chamber 1.

The sealing cover 212 is fixed with the control chamber 1 through bolts, the bolts are arranged on the inner side of the control chamber 1, other parts of the sealing cover 212 are only attached to the top of the oil tank chamber 2, the bolts are not fixed, the sealing cover 212 can only be broken completely by external force when being broken, the sealing cover 212 cannot be detached through the bolt detaching mode, the bolts are fixed inside the control chamber 1, the door leaf 11 of the control chamber 1 needs to be opened before the bolts are detached, the door leaf 11 is antitheft through the lock body 12, and the difficulty of opening the door leaf 11 is also large.

To explain further, the edge of the hand hole 02 is protruded upward, and the sealing plate 211 is pressed against the protruded edge of the hand hole 02 and fixed to the tank chamber 2 by bolts.

The edge of the hand hole 02 protrudes upward, and the sealing plate 211 is pressed on the protruding edge of the hand hole 02, so that the hand hole 02 with the protruding edge can play a good sealing role even in heavy rain, and rainwater is prevented from entering the oil tank chamber 2 from a gap between the sealing plate 211 and the hand hole 02.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
