Abstract
The utility model belongs to a road traffic facility, and provides an antitheft well cover made of super-high molecular composite plastic, which comprises a well cover (2), a well cover support seat (1), and an antitheft lock which is composed of a gear (5) and a rack bar (6) mechanism, wherein the cylindrical gear (5) and the rack bar (6) are fixed on a lock body (4) which is fixed to the bottom of the well cover (2); the gear (5) is provided with a central shaft hole (8), and a corresponding circular hole is formed on the well cover (2); one end of the rack bar (6) is provided with a lock bolt (7). The utility model uses the gear and the rack bar mechanism to lock the well cover, so the utility model has the characteristics of reliable locking and convenient opening, and is suitable for severe conditions.
Description
(1) technical field:
The utility model belongs to road traffic facility, mainly proposes a kind of supra polymer composite plastic anti-stealing manhole cover.
(2) background technology:
The well lid that is used for municipal highway, communication, water supply line is by cast iron, clad steel fiber and three kinds of material manufacturings of glass fiber reinforced plastic.And the conventional casting iron well lid that uses is owing to can handle as scrap iron, stolen phenomenon often takes place, and bring a lot of hidden danger for thus the safety of pedestrian, vehicle, frequent generation damaged vehicle, the situation that the pedestrian is injured, though and its anti-theft device of well lid that proposes now has multiple structure design, but the anti-theft device practicality is not strong mostly, inapplicable rugged environment.As have the well lid structure of latch lock, use a period of time after, be easy to corrosion, produce that spring is ineffective does not open, do not have antitheft effect basically.
(3) summary of the invention:
The purpose of this utility model is to propose a kind of supra polymer composite plastic anti-stealing manhole cover, makes its structure design have locking reliably, the characteristics of opening conveniently and being suitable for using under the mal-condition.
The technical scheme that the utility model is finished its invention task proposition is: it comprises the theftproof lock that well lid bearing, well lid and gear, rackwork constitute, and cylindrical gear and tooth bar are fixed on the lock body, and lock body is by being bolted to the well lid bottom; Cylindrical gear has central shaft hole and have corresponding circular hole on well lid, and an end of tooth bar is provided with lock bolt.
During use, well lid is placed on the well lid bearing, inserts in the central shaft hole of gear with the circular hole of key (being similar to the axostylus axostyle of band handle) by well lid, transmitting gear moves tooth bar, and the lock bolt of tooth bar one end cooperates with the well lid bearing, with Manhole cover lock; When opening well lid, make the gear backward rotation, tooth bar moves, and the lock bolt of tooth bar one end and well lid bearing break away from, and well lid upwards can have been removed.
The utility model adopts gear, rackwork to lock well lid, makes it have locking reliably, and it is convenient to open; And be suitable under the mal-condition characteristics used.
(4) description of drawings:
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is Figure 1A partial enlarged drawing.
Accompanying drawing 3 is Fig. 2 N-N sectional drawing.
Among the figure, 1-well lid bearing, 2-well lid, 3-bolt, 4-lock body, 5-roller gear, 6-tooth bar, 7-lock bolt, 8-gear centre axis hole.
(5) specific embodiment:
The embodiment that provides is in conjunction with the accompanying drawings further specified its structure:
As shown in Figure 1, the utility model mainly comprises well lid bearing 1, well lid 2 and the theftproof lock that is made of gear 5, tooth bar 6 mechanisms, and cylindrical gear 5, tooth bar 6 are fixed on the lock body 4; Be that tooth bar 6 is with gear 5 engagements and along the chute move left and right on the lock body.Lock body 4 is fixed on well lid 2 bottoms by bolt 3, and cylindrical gear has central shaft hole 8 and have corresponding circular hole on well lid, and an end of tooth bar 6 is provided with lock bolt 7.Well lid bearing 1 and well lid 2 can adopt the supra polymer composite plastic to make.
Claims (1)
