Abstract

The utility model relates to an anti-theft well cover and open device, comprising an anti-theft safety well cover, a ring seat, and an open device. The anti-theft well cover and open device is characterized in that the bottom face of the anti-theft safety well cover 4 is provided with more than two spring steel sheet clamps 2 which can clamp the anti-theft safety well cover 4 and the ring seat 1; the open device comprises a support rod 8 and a transverse support rod 7 which can be folded to furl, a draw rod 5 which can be lifted, etc. The anti-theft well cover and open device has the advantages that the anti-theft well cover can not be easily stolen; car damage and people death accidents because the well cover is stolen are avoided.

Description

Anti-theft well cover and open device

The utility model relates to a kind of anti-stealing manhole cover and opening device.

In existing all kinds of upper and lower water channels and road surface manhole cover seat, generally all do not establish antitheft safety device, must special-purpose opening device or instrument yet.Prized and stolen phenomenon so occur well lid often, cause pedestrian and vehicle to lack the sense of security, occurred the car crash accident often.

The purpose of this utility model is to provide a kind of anti-theft security well lid and opens isolated plant, and wishing provides safety guarantee because applying of it can prevent the generation of stolen phenomenon easily of all kinds of well lids to pedestrian and vehicle.

The utility model is realized by following approach:

This anti-stealing manhole cover and opening device are by anti-theft security well lid, ring support and special opening device, constitute by anti-theft security well lid, ring support and special opening device two parts, its described anti-theft security well lid, ring support are made up of well lid 4, ring support 1, are characterized in that described well lid 4 bottom surfaces are provided with the spring steel integrated circuit board 2 that well lid 4 and ring support 1 can be connected together more than 2.

Described special opening device is made up of pull bar 5, handle 6, cross bar 7, cramp bar 8, body frame 9, hoisting nut 11, its main points be evenly distribute on the described body frame 9 upper end circumference, articulated three cross bars 7, the outer end vertical direction of this cross bar is respectively established a cramp bar 8, one threaded pull bar 5 is set in the described body frame central duct, the lower end of this pull bar has a card bank 9, and settle a hoisting nut 11 on the face of the body frame that its upper end is close to, in the jack on limit, described hoisting nut side handle 6 is being set.

According to the anti-stealing manhole cover and the opening device thereof of above schematic design, to compare with well lid that passes through usefulness now and ring support, its advantage is that well lid combines with ring support firmly, non-special tool is difficult for opening easily stolen, can effectively prevent the generation of car crash accident.

Accompanying drawing 1 is well lid, ring support structural representation;

Accompanying drawing 2 is well lid, ring support structural representation;

Accompanying drawing 3 is special opening tool construction schematic diagrames;

Accompanying drawing is a special opening instrument schematic top plan view.

The each several part title is as follows among the figure:

1---ring support, 2---spring steel integrated circuit board, 3---screw, 4---well lid, 5---pull bar, 6---handle, 7---cross bar, 8---cramp bar, 9---Ka Kan, 10---body frame, 11---hoisting nut.

Further describe the utility model below in conjunction with accompanying drawing, and provide embodiment.

What Fig. 1, Fig. 2 provided is the form of structure of two kinds of well lids, ring support.Its concrete structure is to be equipped with some (more than 2) spring steel integrated circuit board 2 at well lid 4 bottom surface peripheries; Described spring steel integrated circuit board 2 is fixed on the well lid 4 by screw 3, and is stuck in the depression position of ring support by spring steel integrated circuit board 2, well lid 4 is connected with ring support 1 is one.When practice,, slightly exert pressure and spring steel integrated circuit board 2 can be pressed in the depression of ring support 1 as long as well lid 4 is put on the ring support 1.

Fig. 3, special opening device shown in Figure 4 are by pull bar 5, handle 6, cross bar 7, cramp bar 8, body frame 10.Hoisting nut 11 is formed, its described body frame 10 upper end edge circumferential edge are articulated three cross bars 7 of distribution evenly, the outer end vertical direction of this cross bar 7 is respectively established a cramp bar 8, one pull bar 5 that is threaded screw thread is set in described body frame 10 central duct, the lower end of this pull bar 5 has a card bank 11, and its upper end is close to and is settled a hoisting nut 11 on the face of body frame 10, in the jack of described hoisting nut 11 sides handle 6 is being set.

This special opening device will be placed on outside well lid 4 circumferential edge perpendicular to three cramp bars of cross bar 7 in use, simultaneously pull bar 5 is transferred, and the card bank 11 of its lower end is probeed in the hole clipping on the well lid 4, well lid 4 can be blocked after turning an angle.When further driving handle, make hoisting nut 11 when a certain direction is rotated, 5 on pull bar moves upward, and makes the spring steel integrated circuit board 2 that is fixed on the well lid 4 and is stuck in ring support 1 depression break away from ring support 1, and well lid 4 is separated with ring support, reaches purpose of opening.

This special opening device is the time spent not, cramp bar 8 can be separated with cross bar 7, makes cross bar 7 around the folding gathering of rocker bar bearing, so that carry simultaneously.
