Description
Technical field
The utility model relates to a kind of inspection shaft lid that slide block device is arranged.
Background technology
The inspection shaft lid is often to be used to the extensive product that adopts in the road pavements such as cable, coal gas, motor vehicle major trunk roads, sidewalk; The inspection shaft lid comprises a well seat foundry goods and a well lid foundry goods, after well seat foundry goods and the connection of well lid foundry goods, opens well lid with crow bar and unlocking tool; If the well lid foundry goods is not consolidated after being opened to maximum angle; The well lid foundry goods covers down through regular meeting automatically, causes security incident, and security performance reduces.Therefore, be necessary this is improved.
Summary of the invention
The connection head that the task of the utility model is the above-mentioned deficiency that overcomes conventional inspection shaft lid, provide a kind of well lid has the inspection shaft lid of slide block device.The task of the utility model is achieved through following technical scheme:
The described inspection shaft lid of the utility model comprises well seat foundry goods, well lid foundry goods, connecting axle, and connecting axle passes well lid foundry goods through hole connection well seat and well lid foundry goods on one side; One side of well lid foundry goods has the bottom to be circular-arc connector, and connector is connected with the rectangular boss of through hole; Inspection shaft is covered with slide block, and slide block is placed in the through hole of rectangular boss, and the bottom of slide block is the plane, and slider head one end is provided with the arc surface that becomes angle with the baseplane, and other end afterbody is provided with tapered hole; Slide block has tapering, and head is big, afterbody is little; Be provided with second boss with the corresponding well seat of rectangular boss foundry goods, second boss is below rectangular boss.
Compare with prior art, the inspection shaft lid of the utility model has overcome the above-mentioned unsafe factor of existing inspection shaft lid, and the utility model is simple in structure, light; Easy operating; The staff is operated does not have trouble and worry, the advantage that stability is high, and installation and unlatching are all very convenient.The utility model structure is a kind of technological innovation, and is useful to traffic safety, environmental protection again, is a kind of product that meets safety, environmental requirement, should vigorously promote the use very much.

The specific embodiment
Specific embodiment below in conjunction with accompanying drawing further specifies the utility model.(but not being restriction) to the utility model.
As shown in the figure, the inspection shaft lid of the utility model comprises a well seat foundry goods 1 and a well lid foundry goods 2, and connecting axle, connecting axle pass well lid foundry goods through hole on one side, connecting axle connection well seat and well lid foundry goods (built-in connected mode); As shown in Figure 2, one side, connect the rectangular boss 4 that head 3 is connected with through hole at the circular-arc connection head 3 of being provided with of well lid foundry goods 2; The inspection shaft of the utility model is covered with slide block 5, and slide block 5 is placed in the through hole of rectangular boss 4, and head one end of slide block 5 is provided with the arc surface that forms an angle with the baseplane, and other end afterbody is provided with tapered hole.Be provided with second boss 6 of certain width with rectangular boss 4 corresponding well seat foundry goods 1.
As shown in Figure 4, second boss 6 is below rectangular boss 4, and connector 3 is connected with rectangular boss 4, and slide block 5 is placed in the through hole of rectangular boss 4.The section shape of the through hole of rectangular boss 4 is identical with the section shape of slide block, and is gapped between them.
As shown in Figure 5, link to each other with the well seat foundry goods one side at position of second boss 6 is that interior concaved circular cambered surface 8, the second boss, 6 another sides and well seat foundry goods connect into angle face 7.When well lid foundry goods 2 is opened rotation, drive slide block 5 and rotate together, slide block 5 self has tapering.In the process that well lid foundry goods 2 is opened; Slide block 5 rotation and slippage downwards, slide block 5 have a circular-arc head, from interior concaved circular cambered surface 8; Move to angle face 7 places; Then, the baseplane of slide block 5 and angle face 7 (that is: second boss, 6 another sides and well seat foundry goods connect into angle face 7) contact, and the head of slide block 5 tightly withstands on the well seat foundry goods 1.Like this, well lid foundry goods 2 does not turn in not understanding under the force urges outside yet, mentions the security performance of inspection shaft lid greatly.
As shown in Figure 6, when well lid is closed, earlier slide block 5 is upwards pulled up under the effect of upward force, slide block 5 leaves second boss 6 of well seat foundry goods 1.Can not come off because of the big little structure of tail of head of slide block 5 causes slide block 5 to receive power upwards yet, only utilize working hammer to knock under the effect of afterbody of slide block, the slide block inspection shaft lid that could come off fully at installation personnel.
More than be an embodiment of the utility model; Just inspection shaft lid as shown in Figure 1 is circular sketch map; And the inspection shaft of using the utility model covers; Inspection shaft lid shape can also be designed to other different shapes according to actual needs, is shaped as rectangle or shapes such as square or ellipse or prismatic like the inspection shaft lid.All those skilled in the art, modification that it is done because of the utility model spirit category or the change that is equal to all ought to be included within this case patent application protection domain.
