Abstract
The utility model pertains to the technical area of lock and discloses a well cover locking device. The main technique scheme of the well cover locking device is that the device comprises a shell, a hydraulic mechanism which is composed of a cylinder and a plunger piston and is arranged on the shell, a lever which is connected with the end of the plunger piston, and a elastic return member and a set bar which are connected to the two ends of the lever. The well cover locking device has the advantages of that the structure is simple and practical and the production cost is low. The utility model solves the problem is the prior art that the structure of the lock of the well cover is complicated.
Description
Technical field
The utility model belongs to lock technology field, relates in particular to a kind of locking device that is used on the well lid.
Background technology
Current, constitute the various vertical shafts of supply and drain water system, combustion gas and the systems such as heat distribution pipeline system, power supply and telecom communication in city, employed well lid major part is a casting iron well lid, and this casting iron well lid takes place repeatedly owing to the stolen phenomenon of the reason of society, not only influence the municipal appearance of the city, and tend to damage to vehicle and pedestrian.Stolen in order to prevent well lid, most of well lid takes to be provided with in its bottom the measure of locking device.As the utility model patent that the patent No. is 02239910.0, name is called manhole antitheft lock, this patent is provided with in the bottom of well lid and comprises fixedly dead bolt, movable dead bolt, fixed mechanism, transmission mechanism and the theftproof lock that is made of drive circuit and control circuit.Because the theftproof lock of the type has comprised drive circuit and control circuit, exist therefore that composed component is many, complex structure and defect of high cost.The inventor has applied for that on April 30th, 2005 key name is called anti-stealing manhole cover, the patent No. is the utility model patent of 200520024004.X, although the lockset in this anti-stealing manhole cover is controlled without electronic circuit, its structure is more complicated, not too practical aborning still.
The utility model content
The purpose of this utility model just provide a kind of simple in structure, be used in locking device on the well lid specially.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of well lid locking device includes housing, and this housing is provided with the hydraulic mechanism that is made of cylinder barrel and plunger, and described plunger end is connected with lever; Be connected with elastic reset member between one end of this lever and housing, the other end is fixedlyed connected with the dead bolt that can slide.
In addition, described housing is provided with fixed mechanism.
Well lid locking device provided by the utility model compared with prior art, because this well lid locking device has only housing and is arranged at the dead bolt formation of hydraulic mechanism, lever, elastic reset member and realization well lid locking function on this housing, therefore has the advantage of (low cost of manufacture) simple in structure and practical.
Description of drawings
The structural representation of the well lid locking device that Fig. 1 provides for the utility model;
Fig. 2 is the structural representation that is fixed on the locking device of one with well lid;
Fig. 3 is the structural representation of hydraulic mechanism in the locking device.
The specific embodiment
The structure and the use principle of the well lid locking device that the utility model is provided below in conjunction with accompanying drawing are described in further details.
As shown in Figure 1, the structural representation of the well lid locking device that provides for the utility model.Promptly the structure of this well lid locking device includes the housing 1 that can be fixed together with well lid, this housing is provided with the hydraulic mechanism that is made of cylinder barrel 2 and plunger 3, wherein plunger end is fixedlyed connected with lever 4, and be connected with the spring 6 (or other flexible members) that is used for plunger 3 and resets between an end 5 of this lever and housing, the other end is fixedlyed connected with the dead bolt 8 in being fixed in sliding tray 7.
During use, as shown in Figure 2, well lid locking device 9 is fixed in the downside of well lid 10 by fixing hole 11, makes its dead bolt 8 can be stuck in the downside of walling crib 12, to realize well lid and walling crib are locked as the function of one.
Its operating principle is, by being arranged at the circular hole 13 (as shown in Figure 3) on the well lid, by oiling in the cylinder barrel of oil pipe 14 in hydraulic mechanism, makes that plunger promotes lever and spur dead bolt to move by oil pump, can realize opening the purpose of well lid; Oil pump resets, and then plunger is under the effect of the spring that resets, and pull lever also drives the downside that dead bolt is inserted into walling crib 12, makes well lid and walling crib be locked as one.Thereby realize antitheft purpose.
