Abstract
The utility model relates to a manhole cover, particularly an anti-theft manhole cover. For solving the problems that the existing anti-theft manhole cover is not convenient to open, and is easy to damage by means of rigid torsional buckling, the utility model provides the anti-theft manhole cover capable of fully opening, which is composed of a manhole cover plate and a manhole cover seat, wherein, the manhole cover plate is hinged on a connecter which is hinged on the manhole cover seat. The utility model has the advantages of good anti-theft effect and free and flexible opening and closing; the anti-theft manhole cover capable of fully opening can not generate a cover clamping phenomenon, and can prevent the damage by means of rigid torsional buckling; the manhole cover is completely opened, which does not influence operation.
Description
The utility model belongs to a kind of well lid, particularly anti-stealing manhole cover.
Anti-stealing manhole cover has two kinds at present, and a kind of is that the well lid plate is locked on the manhole cover base, and utilizes special tool to open well lid, if special tool is made by stealer, the well lid for producing in batches then loses antitheft meaning.Another kind is that the well lid plate is hinged on the manhole cover base, the well lid plate can not arbitrarily be taken away, but because the physical dimension and the residing particular surroundings of well lid plate and manhole cover base, it is inconvenient to make the well lid plate open and close, easily stuck, and after the well lid plate opened, well lid plate and manhole cover base formed rigid support, thereby stealer easily adopts the means of rigidity torsional buckling to carry out destructiveness pilferage.
The purpose of this utility model is to address the above problem, and a kind of good anti-theft effect is provided, and opens and closes full open anti-stealing manhole cover easily.
It is made of the utility model well lid plate and manhole cover base, and the well lid plate is hinged on the connector, and connector is hinged on the manhole cover base.
Card lid phenomenon can not take place in the utility model good anti-theft effect, switching nimbly and freely, the destruction that can prevent means such as rigidity torsional buckling, and the well lid full open does not influence operation.
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the manhole cover base partial view;
Fig. 4 is the structural representation of the anti-saw salient point on the connector;
Fig. 5 is for having the structural representation of lock body on the utility model well lid plate.
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, 2, it is made of the utility model well lid plate 2 and manhole cover base 1, and well lid plate 2 is hinged on the connector 5, and connector 5 is hinged on the manhole cover base 1.Owing to connect well lid plate 2 and manhole cover base 1 by connector 5, well lid plate 2 can be along connector 5 upsets, and connector 5 can form full open along manhole cover base 1 upset again, does not influence operation.And the well lid plate after opening 2 do not form rigid support with manhole cover base 1, is difficult to destroy good anti-theft effect with the means of rigidity torsional buckling.Simultaneously two articulated structures are difficult for taking place stuck phenomenon.
As shown in Figure 1, well lid plate 2 is provided with groove 3, and manhole cover base 1 is provided with groove 4, and connector 5 is stuck in two grooves, is convenient to install, and can keeps the planarization of well lid.As shown in Figure 2, the hinge hole 6 with manhole cover base on the connector 5 is the prolate hole, is beneficial to adjust well lid plate 2 to the distance between the manhole cover base 1, makes switching more flexible.
As shown in Figure 3, there is projection 8 at the two ends of the well lid plate supporting seat 7 on manhole cover base 1, are convenient to the support and the unlatching of well lid plate.
As shown in Figure 4, anti-saw salient point 9 is arranged in the both sides of connector 5.Can prevent to strengthen anti-theft effect with the sawed-off jointed shaft of hacksaw.
As shown in Figure 5, can be equipped with lock body on the utility model well lid plate 2, lock body is made of lock pin 12, supporting seat 11 and bolt 10, supporting seat 11 is fixedly mounted on the well lid plate 2, lock pin 12 is hinged on the supporting seat 11, and bolt 10 withstands on a side of lock pin 12, and is installed on the well lid plate 2.During the closed-in well cover plate, lock pin 12 clockwise rotates, cross the well lid plate supporting seat on the manhole cover base after, pin.When opening, loose bolts 10 gets final product.Bolt head can adopt various structures, and is used with special sleeve spanner, can make the layman be difficult to open the well lid plate like this.
