CN201326182Y - Anti-theft device of well lid - Google Patents

Abstract

The utility model discloses an anti-theft device of a well lid, which comprises a connecting rod and a slideway fixed in the inner side of a base, wherein one end of the connecting rod is hinged with the bottom surface of the well lid, and the other end thereof is arranged in the slideway. Through the action of the slideway and the connecting rod, the well lid can not be fully separated from the base when the well lid is lifted; under the condition of satisfying the normal use, the well lid can not be stolen or removed, thus improving the safety of using the well lid; a horizontal section inside the slideway effectively prevents the well lid from moving upward and downward on the base, and reduces the vibration of the well lid, and achieves the self-locking of the well lid so as to improve the reliability and scientificity of using the well lid; the whole structure is simple and reasonable, and unnecessary economic losses are avoided and the maintenance cost is reduced; and the utility model is particularly suitable for being promoted and used in various well lids.

Description

Well cover antitheft device

Technical field

The utility model relates to a kind of well lid, particularly a kind of for prevent well lid stolen that be provided with, be connected the well cover antitheft device between well lid and the base.

Background technology

Existing well lid all is directly to cover on well head in use, does not have any safeguard measure, and anyone can move and move out easily.Because well lid is mainly used in the public facility construction, its position focuses mostly on and is distributed on road and the highway, quantity is many, distribution is wide, the well lid shock resistance of iron casting is good, resistance to pressure is strong, volume is big, heavy, so well lid phenomenon stolen or that moved by the automobile side pressure often takes place, make and occur black hole one by one on the highway, not only influence the safety of pedestrian and driving vehicle, the personnel that cause easily injure, destroy social stability, return road upkeep and use and brought great influence, cause the situation that maintenance cost increases, working strength increases.Improve reliability and safety that well lid uses,, avoid unnecessary loss, just become problem to be solved in the utility model for exposed well lid installs anti-theft device additional.

Summary of the invention

In view of above-mentioned deficiency of the prior art, the utility model aims to provide and a kind ofly can prevent effectively that well lid is stolen, connects well cover antitheft device simple, easy to use.

The utility model is achieved through the following technical solutions:

A kind of well cover antitheft device comprises a connecting rod and a slideway that is fixed on side-lower in the base, and described connecting rod one end is hinged on the well lid bottom surface, and the other end is positioned at slideway and matches with slideway.

Described slideway is ' T ' font sealing slideway that has the inclination angle.

Described sealing slideway the inner also is provided with horizontal slideway.

Described connecting rod is a junction plate, and junction plate one end is hinged on the well lid bottom surface, and the other end matches with the sealing slideway of base inboard.

The longitudinal cross-section of described junction plate is shaped as ' n ' font.

Well cover antitheft device described in the utility model, by the restriction of sealing slideway and the interconnect function of junction plate, make well lid when base starts, well lid can not separate fully with base, all the time be in a kind of state of connection, under the situation that satisfies normal use needs, guaranteed that effectively well lid can not stolen or take off, improved the safety that well lid uses.Well lid is built the back to inboard slight promotion of anti-theft device link, the contact jaw of junction plate has been positioned on the horizontal segment of sealing slideway, prevented the upper and lower play of well lid on base, realized the self-locking to well lid, improved reliability and science that well lid uses, total is simple, reasonable, use flexibly, effectively avoided unnecessary economic loss, reduced maintenance cost, be particularly suitable on various well lids, promoting the use of.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, a kind of well cover antitheft device described in the utility model, comprise a connecting rod and a slideway 5 that is positioned at base 2 side-lowers, connecting rod is a junction plate 3, the longitudinal cross-section of junction plate 3 is shaped as ' n ' font, junction plate 3 one ends are hinged on well lid 1 bottom surface, and the other end matches with the slideway 5 of base 2 inboards.Slideway 5 is ' T ' font sealing slideway that has the inclination angle, and it is convenient, smooth and easy that the inclination angle can guarantee that junction plate 3 one ends slide, and the inclination angle size is relevant with the angle that the length of junction plate 3 reaches ' n ' font, can arrange in pairs or groups arbitrarily, design.The inner at ' T ' font sealing slideway 5 also has one section horizontal slideway 6.Well lid 1 after building promotes to sealing slideway 5 inboard levels, the contact jaw 4 of junction plate 3 and sealing slideway 5 moves inward horizontal segment 6 places that enter into sealing slideway 5 behind the certain distance, contact jaw 4 can effectively prevent well lid 1 on base 2 vertical tremor and play self-locking action.

When needs are raised well lid 1, at first well lid 1 is moved some distances a little to sealing slideway 5 outsides, the contact jaw 4 of ' n ' font junction plate 3 is shifted out from the horizontal segment 6 of sealing slideway 5, eliminate the self-locking action of 4 pairs of well lids 1 of contact jaw under the common state.Then, start well lid 1, well lid 1 relative ' n ' font junction plate 3 hinged ends upset, the contact jaw 4 of junction plate 3 slides in having the sealing slideway 5 at inclination angle relatively, and well lid 1 is opened, because slideway 5 is the sealing slideway, so the contact jaw 4 of junction plate 3 can not skid off from slideway 5, well lid 1 can not separate fully with base 2, and junction plate 3 makes well lid 1 be stolen or to take away, has guaranteed the safety that well lid 1 uses.And after covering well lid 1, contact jaw 4 on the junction plate 3 can be slided back along sealing slideway 5 again, promote the medial movement of well lid 1 to sealing slideway 5, the contact jaw 4 of ' n ' font junction plate 3 slides on the horizontal segment 6 of sealing slideway 5 again, well lid 1 can be at the upper and lower play that makes progress under the effect of ' n ' font junction plate 3 like this, send Rack or the possibility that well lid 1 is turned on one's side takes place when having reduced well lid 1, guaranteed reliability and science that well lid 1 uses by weight side pressures such as automobiles.
