Abstract
The utility model provides a connecting device capable of preventing a cover frame from closing accidentally and relates to the technical field of cover frame connecting devices. The connecting device capable of preventing the cover frame from closing accidentally comprises a cover body and a frame body, and the cover body is connected on the frame body through a connecting device. The connecting device capable of preventing the cover frame from closing accidentally is characterized in that the connecting device comprises a clamping buckle arranged on the cover body and a clamping groove arranged on the frame body, wherein a rectangular fixing groove is arranged in the clamping buckle, a round rotating groove is communicated in the rectangular fixing groove, and two cuboid rotating shafts are arranged in the clamping groove. The connecting device capable of preventing the cover frame from closing accidentally has the advantages that rotation and fixation of the cuboid rotating shafts can be achieved by matching of the round rotating groove and the rectangular fixing groove, and the phenomenon that workers are hurt due to accidental closing of the cover body after the cover body is opened can be avoided effectively. The integrated connection of the cover frame can be achieved through bolts, and the anti-theft purpose of can be achieved effectively. The bolts and the clamping buckle are constrained in the clamping groove, and the damage on a road surface because of frequent opening and closing of the cover body can be avoided.
Description
Technical field
The linkage that prevents the unexpected closure of cover frame that the utility model relates to a kind of antitheft, anti-unexpected closure and avoids road pavement to damage.
Background technology
Well lid is the closure that leads to the top, access of underground installation, and the place of the communal facilitieies such as every installation tap water, telecommunications, electric power, combustion gas, heating power, fire-fighting, environmental sanitation all needs to install well lid.Along with the develop rapidly of China's economy, China's infrastructure construction has welcome again a new cycle, and the market demand of well lid in urban planning and road construction is huge.But being connected always between well lid and the following framework comes with some shortcomings, and well lid is insecure with being connected of framework, causes well lid stolen, causes the thing of security incident to happen occasionally; The form that generally all adopts hinges that is connected of well lid and following framework, after well lid was opened, the staff pierced underground work, and the unexpected closure of well lid is easy to cause following staff's personal injury; The frequent rotation that is connected hinge between well lid and the framework is easy to cause the destruction on road surface around the well lid, and the road pavement traffic consists of very adverse influence.
The utility model content
The purpose of this utility model is to provide the linkage that prevents the unexpected closure of cover frame that a kind of antitheft, anti-accident is closed and avoid road pavement to damage.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of unexpected closed linkage of cover frame that prevents, comprise lid and framework, described lid is connected on the described framework by a linkage, it is characterized in that: described linkage comprises the buckle of being located on the described lid, and be located at draw-in groove on the described framework, be provided with a rectangle holddown groove in described buckle inside, also connection is provided with a circular rotation slot in described rectangle holddown groove, also is provided with two cuboid turning cylinders in described draw-in groove.
Also be provided with two pairs of bolts hole that run through described rectangle holddown groove on described buckle, bolt passes described bolt hole and is fixed on the described buckle.
The corner angle of described turning cylinder are arc.
The width of described rectangle holddown groove is between the section radius and water chestnut length of described cuboid turning cylinder.
The beneficial effect that the utlity model has is: cooperate the rectangle holddown groove to realize the rotation of cuboid rotating shaft and fixing by circular rotation slot, can prevent effectively that the unexpected closure after lid is opened from causing injuring the staff; Realize that by bolt the cover frame one connects, and effectively realizes antitheft; All bolts, buckle are limited in the draw-in groove, avoid the frequent folding road pavement of lid to damage.
Description of drawings
Fig. 1 is the utility model: prevent the unexpected closed linkage overall structure schematic diagram of cover frame;
Fig. 2 is the utility model: the structural representation of lid;
Fig. 3 is the utility model: the structural representation of framework.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Embodiment: shown in Fig. 1-3, a kind of unexpected closed linkage of cover frame that prevents, comprise lid 1 and framework 2, described lid 1 is connected on the described framework 2 by a linkage 3, described linkage 3 comprises the buckle 4 of being located on the described lid 1, and is located at the draw-in groove 5 on the described framework 2, is provided with a rectangle holddown groove 6 in described buckle 4 inside, also connection is provided with a circular rotation slot 7 in described rectangle holddown groove 6, also is provided with two cuboid turning cylinders 8 in described draw-in groove 5.
Also be provided with two pairs of bolts hole 9 that run through described rectangle holddown groove 6 on described buckle 4, bolt 10 passes described bolt hole 9 and is fixed on the described buckle 4.
The corner angle of described turning cylinder 8 are arc.
The width of described rectangle holddown groove 6 is between the section radius and water chestnut length of described cuboid turning cylinder 8.
The open-close ways of described lid may further comprise the steps:
1) upset lid 1.In described circular rotation slot 7 interior rotations, make described lid 1 be 90 ° with the road surface by described cuboid turning cylinder 8.
2) fixing lid 1.After described lid 1 is 90 ° of positions with the road surface, because the self gravitation effect so that described cuboid turning cylinder 8 is positioned at described rectangle holddown groove 7, realizes the fixing of described lid 1, prevent described lid 1 unexpected closure.
3) closed lid 1.Described lid 1 is upwards mentioned, so that described cuboid turning cylinder 8 is positioned at described circular rotation slot 7, upset and closed described lid 1.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
