Abstract
The invention relates to a door with a hydraulic counter-lock device. The door mainly comprises an oil cylinder, oil, a piston, a stop block and a door panel. The oil cylinder is arranged on the lower part of the door panel, the oil cylinder is filled with the oil, one end of the oil cylinder is sealed by the piston, and the other end of the oil cylinder is sealed by the stop block. A groove is formed on the door panel, so that the stop block can stretch into the groove. A cylinder body of the oil cylinder is variable in section, and the cross section of one end, adjacent to the piston, of the cylinder body is smaller than that of the end, adjacent to the stop block, of the cylinder body. The shape of the cylinder body and the position of the piston can be designed at will. When an article is arranged on the piston, the piston is pushed to move downwards, the oil in the oil cylinder is pushed, the stop block on the other end moves upwards to stretch into the groove in the door panel, and a function for preventing the rotation of the door panel is realized. The door has characteristics of simple structure, good concealing performance and the like.
Description
Technical field
What the present invention relates to is a kind of safety device, particularly a kind of door with hydraulic pressure reverse locking device in a field.
Background technology
In order to antitheft better, door needs to possess back locking function.The current technology of locking has multiple, such as " a kind of insertion-core lock with back locking function " (201110182461.1), " having the electronic lock of mechanical key back locking function " (200710072846.6), " Fingerprint Lock of improvement back locking structure " (201010234835.5) etc.
But these technology are all add in the inside of conventional lockset or improve back locking function, and professional thief can understand fully principle and internal construction targetedly, and then realize cracking.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, a kind of door with hydraulic pressure reverse locking device is provided.
Structure of the present invention comprises oil cylinder, oil, piston, block, door-plate.Oil cylinder is positioned at the bottom of door-plate, inner extend oil, and one end is closed by piston, and the other end is closed by block.Fluted bottom door-plate, block can be allowed to stretch into into.
Described oil cylinder, cylinder body is variable cross-section, and the sectional area near one end of piston is less than the sectional area of the one end near block.
Described block is the cuboid be made up of metal material.
When placing arbitrarily an object on piston, promotion piston being moved down, and then promotes in-oil cylinder oil, the block of the other end is moved up, extending in the groove in door-plate, realizing the function stoping door-plate to rotate.
The present invention can make stranger after opening the conventional lockset on door, still can not open the door, therefore have good theftproof.When house owner is in indoor, an object (be such as water tumbler, vase, pot bowl etc.) can be chosen arbitrarily and be placed on piston.In addition, the position of shape of block and piston can be designed arbitrarily, and stranger is difficult to the position finding piston.When house owner will go out, remove the object be positioned on piston, because the deadweight of block making it toward declining, departing from the groove of door-plate, no longer limiting the movement of door-plate.
Visible, the present invention can make door have multiple tracks security perimeter.There is the features such as structure is simple, good concealment simultaneously.
Accompanying drawing explanation
Accompanying drawing 1 is the generalized section of the door of band hydraulic pressure reverse locking device.
Detailed description of the invention
Below embodiments of the invention are elaborated: the present embodiment is implemented under premised on technical solution of the present invention, give detailed embodiment and process, but protection scope of the present invention is not limited to following embodiment.
First below the position of door-plate 1, place oil cylinder 2, oil body 3 is filled in the inside of oil cylinder 2.
One end of oil cylinder 2 is closed by a piston 4.Piston 4 should be positioned at indoor.
A groove is arranged at the bottom of door-plate 1, has a block 5 immediately below groove, and block 5 is also positioned at another end of oil cylinder 2 simultaneously, and plays closed oil cylinder 2.
House owner can set arbitrarily the position of piston 4.When needs opposite house is locked, an object can be looked for arbitrarily to press on piston 4, promote oil body 3 and make block 5 stretch into the groove of door-plate 1 inside.
Claims (4)
1. the door with hydraulic pressure reverse locking device, is characterized in that, comprises oil cylinder, oil, piston, block, door-plate, and oil cylinder is positioned at the bottom of door-plate, inner extend oil, and one end is closed by piston, and the other end is closed by block.
2. the door of band hydraulic pressure reverse locking device as claimed in claim 1, is characterized in that, fluted bottom door-plate, and block can be allowed to stretch into.
