Abstract

The utility model relates to an inspection well cover locking device which can reduce the phenomenon that the inspection well cover is stolen and damaged after being locked. The structure of the locking device is that guide tubes and positioning baffles, which are matched with locking rods of the locking device are symmetrically arranged at the four directions of the inspection well cover, one end of each locking rod is provided with a limit baffle, a return spring is arranged in the guide tubes and the positioning baffles, the other end of each locking rod is hinged with a stressed arm of the locking device through a pin shaft, rollers with slots and bearing stressed rings form the inspection well cover locking device, wherein the rollers with slots are arranged at the other ends of the stressed arms, and the bearing stressed rings are fixed on certain positions through bolts.

Description

Inspection shaft cover lock is decided device

Affiliated technical field

The utility model relates to a kind of locking device, especially can be comprehensive the locking device of locking inspection shaft lid.

Background technology

At present, along with city and rural development, large quantities of electric wire, optical cable, piping facilities that are arranged on ground all will be displaced to undergroundly to be buried and lays, in order to build these underground installations and conveniently underground installation to be safeguarded and overhauled in the future, produced a large amount of inspection shafts, the appearance of these inspection shafts, brought many troubles also for the user of inspection shaft, the well lid of every metal casting moulding all may become stolen article, the lighter brings property loss, the consequence that the people hinders accident appears in weight person, and this phenomenon all may take place in each city.For the generation that prevents that this kind of thing, relevant departments have also thought a lot of methods, try every possible means on the material of inspection shaft lid, make the inspection shaft lid with some nonmetals, this inspection shaft cover bear for a long time under the situation that automobile rolls unsatisfactory, the material production fatigue failure, using has limitation.In addition, on the locking means of inspection shaft lid, try every possible means, adopt simple machine two-way locking or connect well lid and walling crib with metallic bond, use proof, these methods still can not solve the generation of the stolen thing of well lid, and simultaneously the inspection shaft of these lock modes covers and rolls the impact noise that discontinuity produces in the process at automobile environment is affected.

Summary of the invention

Cover after locking discontinuity in the stolen and use and produce the deficiency that noise exists aspect disturbing residents in order to overcome existing inspection shaft, the utility model provides a kind of Inspection shaft cover lock to decide device, this Inspection shaft cover lock is decided device can not only lock well lid in the four directions, and roll stressed evenly being not easy of process at automobile and damage, noise reduces.

The technical scheme that its technical problem that solves the utility model adopts is: decide on the apparatus structure at Inspection shaft cover lock, the four direction of well lid has been symmetrical arranged with the locking device locking bar supporting guide pipe and positioning baffle has been installed, locking bar one end is installed postive stop baffle, return spring, pack in guide pipe and the positioning baffle, the other end and locking device be subjected to the arm of force hinged with bearing pin, the other end mounting strap grooved roller that is subjected to the arm of force be fixed by bolts on the well lid holding capacity ring of certain position and constitute an Inspection shaft cover lock and decide device.When needs are opened the inspection shaft lid, in dedicated handle fill-in well cover lock hole, the unlatching bolt that is provided with on the handle snaps in and backs down the arm of force in the sheave and drive locking bar and move away well cover cycle inwardly, open the locking bar while of well lid different directions, bolt on the handle opens, and under external force well lid is mentioned, and presses the bolt on the lower handle then, from the well lid lockhole, take out handle, finish the unlatching of well lid.

The beneficial effects of the utility model are, can lock simultaneously in a plurality of directions of well lid, can also alleviate the too early extent of damage of well lid that motor vehicle causes because of unbalance stress when rolling well lid, reduce noise.
