Abstract

The utility model discloses a liquid control valve block anti-theft device. A box cover is arranged above a box body for installing a valve block; one side of the box cover is hinged with the box body, and a projection plate is arranged above the other side; a latch hook of a ring latch passes through the projection plate, and lies flat on the box cover; a cover shell welded on the box cover is arranged around the latch hook to cover the latch hook, and only the lockhole side is left to open to the outside; a part of the box cover positioned in the middle of the latch hook of the ring latch is provided with an inserting groove; a clamp plate in the box body extends from the inserting groove, and passes out through the latch hook of the ring latch; the top of the clamp plate is outwards protruded in the direction of a locking block of the ring latch; when the locking block of the ring latch is unlocked and pulled out, the clamp plate can pass the latch hook of the ring latch; and when the locking block of the ring latch is locked and inwards pressed, the protrusion part at the top of the clamp plate can clamp the locking block. The ring latch for locking the box cover and the box body is covered by the cover shell with the corresponding size, and thieves can not directly knock, smash, saw and pry the ring latch hidden in the cover shell, so the utility model has good anti-theft performance.

Description

A kind of hydraulic control valve piece anti-theft device

Technical field

The utility model relates to anti-theft device, particularly a kind of anti-theft device of valve piece of hydraulic butterfly valve.

Technical background

At present, the public security situation of the hydraulic control valve piece of the hydraulic butterfly valve of the hydraulic system of oil tanker boats and ships is very severe, be very easy to stolen by the copper hydraulic control valve piece on the screw thread fixed hydraulic valve head, the price of these stolen valve pieces is very high, about 500 dollars/, again purchasing needs an expense bigger, brings certain loss to shipyard.Stolen in order to prevent the hydraulic control valve piece, can adopt external lockset that hydraulic valve block is locked in the box body, as Fig. 1, by lockset with the hydrovalve cover lock in box body, thereby prevent that the valve piece is stolen.Yet external lockset is very easy to be broken, sawed-off or pry open, and can not really reach antitheft purpose.

The model utility content

But the utility model main idea is providing a kind of hydraulic valve block anti-theft device of safe antitheft.

A kind of hydraulic valve block anti-theft device, comprise hydraulic valve block is loaded on box body in it, box body is provided with and can passes for the fixed block of hydraulic valve block, hydraulic valve block and box body together are fixed on through hole on the hydraulic pressure valve head, there is lid the top of box body, one side and the box body of lid are hinged, there is flange the top of opposite side, the padlock latch hook passes flange, lie low on lid, there is the case that adapts with the padlock size to be welded on the lid around the padlock, around the padlock and top is covered, only stay the lockhole side externally to open wide, the part that lid is positioned in the middle of the padlock latch hook has slot, has clamp to stretch out in slot in the box body, in the middle of the padlock latch hook, pass, protrude to padlock lock dog direction at its top, and when padlock was opened lock dog and outwards pulled out, clamp can pass the padlock hook, when padlock locking lock dog inwardly was pressed into, the projection at clamp top can block lock dog.

Hydraulic valve block anti-theft device described in the utility model, the box body of hydraulic valve block and the padlock of its lid locking are installed to be covered by being welded on the case that adapts with the padlock size on the lid, only leaving the lockhole direction opens wide, its padlock and latch hook thereof are hidden in fully in the case and are covered by case, stealer can't directly strike, pounds, saws and prize the padlock that is hidden in the case, thereby its theftproof performance is good.

Embodiment

A kind of hydraulic valve block anti-theft device, as Fig. 2, Fig. 3, comprise the inner box body 2 that hydraulic valve block 1 is installed, through hole 3 is arranged on the box body, the fixed block 4 of hydraulic valve block can pass through hole, hydraulic valve block and box body together are fixed on the hydraulic pressure valve head 5, there is lid 6 top of box body, one side and the box body of lid are hinged, and there is flange 7 top of opposite side, and the latch hook 9 of padlock 8 passes flange, lie low on lid, there is the case 10 that adapts with the padlock size to be welded on the lid around the padlock, around the padlock and top is covered, only stay the lockhole side externally to open wide, on the lid of the part in the middle of the padlock latch hook slot 11 is arranged, have clamp 12 to stretch out in slot in the box body, pass in the middle of the padlock latch hook, protrude to padlock lock dog direction at its top, when padlock is opened lock dog 13 and is outwards pulled out, clamp can pass the padlock hook, and when padlock locking lock dog 13 inwardly was pressed into, the projection 14 at clamp top can block lock dog.

For making padlock 8 hooks firmly stable, avoid padlock when opening or lock, in case 10, to rock, make troubles to operation, the flange 7 of padlock latch hook hook can be provided with polylith in the case, about among Fig. 4 being two, the polylith flange can limit the padlock swing, thereby makes padlock open, lock convenient.Latch hook 9 tops of padlock can offset with case 10, and it is convenient to the padlock lock dog more and pushes locking.

In order to reduce the height of case 10, reduce the spacing of case top and padlock 8, the top of case can be provided with groove or slot 15, groove or slot position and clamp 12 position consistency, during lid locking, the top of clamp 12 can be inserted in the slot.The top of clamp inserts in the groove or slot on the case, case will not cover by whole clamp, it can reduce the height of case, reduce the gap of padlock between case top, further improve theftproof performance, simultaneously it also can make the volume of case reduce, also reduction to a certain degree cost.In addition, can also observe the locking state of padlock by slot, can find to push but and the not situation of locking of lock dog, it has improved the reliability of locking.
