Abstract

The utility model relates to a new type of well cover lock. The lock hole of the well cover lock of prior art in the market is often blocked and the lock body is often corroded, and a plurality of locks are easy to be broken by thieves, so that the thieves can purloin the well cover. By the integral cooperation of an alterable key and an angle lock, the angle lock of the utility model is arranged at the edge of the back of the well cover, and a keyhole is opened at the proper position from the angle lock of the well cover. Opening and closing the lock by the alterable key and the angle lock, the utility model can not be blocked, can prevent the collision of the angle lock, and can guard against theft efficiently. The utility model has the advantages of novel design, unblockable keyhole, incorruptible lock body, good theft-proof effect, etc.

Description

A kind of new pattern manhole cover lock

Affiliated technical field

The utility model relates to a kind of new pattern manhole cover lock.

Background technology

At present, the pattern manhole cover lock that uses on the market all is bright lock or the built-in lock that uses in people's daily life generally because well lid, often occurs that lockhole stops up and the corrosion of lock body generally at below ground, have in addition be easy to be destroyed by the robber, thereby steal well lid.Thereby people wish to have and a kind ofly can pin well lid, are not afraid of again and stop up and the anti-stealing manhole cover lock appearance of corrosion.

Summary of the invention

The purpose of this utility model is to provide a kind of new pattern manhole cover lock.

The utility model realizes that by following technical scheme it is made of variable key and angie type lock, and variable key is provided with press rods, grip pipe, key tongue, rotating shaft, and angie type is locked and is provided with dead bolt, connecting rod, rotating shaft.

Beneficial effect

The utlity model has modern design, keyhole be not afraid of stop up lock, body is difficult for by advantages such as corrosion, good anti-theft effect.

Description of drawings and specific embodiment

Accompanying drawing 1 is the variable key structural representation;

Accompanying drawing 2 is an angie type lock construction schematic diagram;

In the accompanying drawing, 1 is that press rods, 2 is that grip pipe, 3 is that rotating shaft, 4 is that key tongue, 5 is that dead bolt, 6 is that rotating shaft, 7 is a connecting rod.

As shown in Figure 1, key tongue 4 is fixedlyed connected with grip pipe 2 by rotating shaft 3, and key tongue 4 can be around the shaft 3 rotates, and press rods 1 can be in one's hands and be slided in the solenoid 2.As shown in Figure 2, dead bolt 5 with can 6 rotate around the shaft after connecting rod 7 is fixedlyed connected.

Get an angie type lock as shown in Figure 2, be fixed in the reverse side of certain well lid by rotating shaft 6, " well " font reinforcing rib by the well lid back side limits the slewing area of connecting rod 7, locking suitable distance with angie type on the well lid, to have a hole be keyhole, the key tongue 4 of the variable key when with Fig. 1 solid line state and grip pipe 2 insert well lid keyhole appropriate depth, promoting press rods 1 moves downward, the wedge angle of press rods 1 lower end partly promotes key tongue 4 upper end wedge angle parts, make key tongue 43 rotate around the shaft, turn to position shown in Fig. 1 dotted line until key tongue 4, rotate grip pipe 2 and press rods 1 this moment synchronously and drive 4 rotations of key tongue, key tongue 4 promotes the connecting rod 7 that angie type shown in Figure 2 is locked, dead bolt 56 rotates around the shaft, when dead bolt 5 is positioned at well seat edge bottom (be provided with a backing pin with the angie type lock about well lid center symmetric position on the well lid and place in advance under the well seat this moment), well lid is in the state of lock, when dead bolt 5 turns to when leaving well seat edge bottom, well lid is in unlocking condition, can open well lid, so organic cooperation by variable key of the present utility model and angie type lock, realized the lock of well lid effectively and opened, owing to be that private key has realized effective antitheft again, the angie type lock is away from lockhole simultaneously, guaranteed that again the angie type lock can not suffer artificial destruction, keyhole is straight-through up and down, thereby be not afraid of obstruction, can pin manhole cover anti-theft so this usefulness is novel, not be afraid of problems such as stopping up and prevent to lock the body corrosion again.

Claims

1. new pattern manhole cover lock, it is to be made of variable key angie type lock etc., it is characterized in that variable key is provided with press rods (1), grip pipe (2), rotating shaft (3), key tongue (4), angie type is locked and is provided with dead bolt (5), rotating shaft (6), connecting rod (7).
