The invention provides a kind of self-locking to prevent turning over inspection well cover and unlocking pin, by inspection shaft ring support, inspection well cover, pin hole, connector, lifting eye, locking mechanism, bullet, latch hook, balance weight, rotating shaft, unlock pin, connecting rod, perpendicular pin composition, described locking mechanism totally three, it is uniformly distributed, hinged it is located at below inspection well cover, when self-locking prevents turning over inspection well cover work, locking mechanism can lock inspection shaft ring support under Gravitative Loads automatically, vehicle rolls inspection well cover in any position and all will not turn on one's side, ensure the coast is clear, vehicle and personal security, when needing to open inspection well cover, only need to insert pin hole by unlocking pin, locking mechanism is unlocked and departs from inspection shaft ring support, inspection well cover is easy to be opened.A kind of self-locking is anti-turns over inspection well cover simple in construction, designs ingenious, safe and reliable.
Description
Technical field
The invention belongs to municipal works field, specifically a kind of self-locking is anti-turns over inspection well cover and unlocks pin.
Background technology
Inspection well cover, is seen everywhere in the streets and lanes in city, and owing to existing inspection well cover location is firm not, vehicle rolls
After be susceptible to rollover, cause vehicle to be absorbed in catch pit port, cause vehicle damage, the accident of casualties happens occasionally.At present,
The anti-technology of turning over of inspection well cover is the most immature, and structure is complicated, it is impossible to promote in municipal works, therefore, and invention a kind of structure letter
Single, safe and reliable anti-turn over the non-long necessity of inspection well cover.
In order to solve above-mentioned technical problem present in prior art, the invention provides a kind of self-locking anti-turn over inspection well cover and
Unlock pin, by inspection shaft ring support, inspection well cover, pin hole, connector, lifting eye, locking mechanism, bullet, latch hook, balance weight,
Rotating shaft, unlock pin, connecting rod, perpendicular pin composition, described locking mechanism totally three, be uniformly distributed, hinged be arranged at basement
Below well lid.
Further, described connector is fixedly installed with inspection well cover, hinged with locking mechanism.
Further, on described inspection well cover, three pin holes are offered in corresponding locking mechanism position.
Further, described unblock pin is hub-and-spoke configuration, and perpendicular pin distributing position is corresponding with pin hole.
Further, described balance weight can ensure locking mechanism lower end flare under Gravitative Loads, locks under normal condition
Hook catches on walling crib seat all the time, and inspection well cover is in locked state all the time.
When self-locking disclosed by the invention prevents turning over inspection well cover work, locking mechanism can lock inspection shaft under Gravitative Loads automatically
Ring support, vehicle rolls inspection well cover in any position and all will not turn on one's side, and ensures the coast is clear, vehicle and personal security, needs
When opening inspection well cover, only need to insert pin hole by unlocking pin, locking mechanism is unlocked and departs from inspection shaft ring support, and inspection well cover holds very much
Easily it is opened.A kind of self-locking is anti-turns over inspection well cover simple in construction, designs ingenious, safe and reliable.

Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
As shown in figs. 1-7, a kind of self-locking of the present invention is anti-turns over inspection well cover and unlocks pin, by inspection shaft ring support 1, inspection well cover 2,
Pin hole 21, connector 22, lifting eye 23, locking mechanism 3, bullet 31, latch hook 32, balance weight 33, rotating shaft 4, unblock pin
5, connecting rod 51, perpendicular pin 52 form, and described locking mechanism 3 totally three is uniformly distributed, and hinged are arranged on inspection well cover 2 times
Face, described connector 22 is fixedly installed with inspection well cover 2, hinged with locking mechanism 3.
On described inspection well cover 2, three pin holes 21 are offered in corresponding locking mechanism 3 position, unlock pin 5 and are
Hub-and-spoke configuration, perpendicular pin 42 distributing position is corresponding with pin hole 21, and described balance weight 33 can ensure that locking mechanism 3 is certainly
Recast lower end flare, under normal condition, latch hook 32 catches on walling crib seat 1 all the time, and inspection well cover 2 is in the lock state all the time.
When a kind of self-locking disclosed by the invention prevents turning over inspection well cover work, the balance weight of locking mechanism causes to be opened outside latch hook, hooks
Living inspection shaft ring support, inspection well cover is in locked state all the time, and vehicle rolls inspection well cover in any position and all will not turn on one's side, and protects
Barrier the coast is clear, vehicle and personal security, when needing to open inspection well cover, only need to insert pin hole, locking mechanism by unlocking pin
Departing from inspection shaft ring support, inspection well cover unlocks and is easy to be opened.
