Specific embodiment
The present invention is described in further detail in the following with reference to the drawings and specific embodiments, is not reality of the invention
It applies range and is confined to this.
As shown in Figures 1 to 7, a kind of dropproof well lid of rectangle described in the present embodiment, comprising: mounting base 1, the installation
Seat 1 is provided with the accommodation groove of square ring, and several accommodating holes are provided on the accommodation groove；Top cover 2, the top cover 2 is in side
The center of shape setting, the top cover 2 is equipped with threaded hole；The bottom surface setting of the top cover 2 is there are four the first engaging lug 21, and four the
One engaging lug 21 is in cross distribution；Locking component 3, the locking component 3 include that screw thread promotes axis 31, tiltedly carves axis 32 and four
Locking rod 33；The threaded one end that the screw thread promotes axis 31 is connected in threaded hole, and the other end connects with the one end for tiltedly carving axis 32
It connects, there are four the second engaging lugs 321 for the other end setting for tiltedly carving axis 32, and four second engaging lugs 321 are in cross
It is distributed, is provided with inclined hole on second engaging lug 321；One end of each locking rod 33 passes through inclined hole and one respectively
Two engaging lugs 321 are hinged and can slide along inclined hole, and the other end activity of the locking rod 33 passes through the first engaging lug 21；It is several anti-
Fall component 4, the dropproof component 4 is set in accommodating hole, and the dropproof component 4 includes the first spring 41 and dropproof perpendicular
Bar 42, one end and the mounting base 1 of first spring 41 abut against, and one end of the other end and dropproof vertical bar 42 abuts against, described
The other end of dropproof vertical bar 42 is under the effect of the first spring 41 outside extended accommodating hole；Cover board 5, the cover board 5 are square ring
Shape setting, and be fixed on the accommodation groove, the internal diameter of the cover board 5 is less than the internal diameter of accommodation groove, and the cover board 5 is equipped with for anti-
Fall the perforation that vertical bar 42 passes through.
The working method of the present embodiment is: preferably, several dropproof 4 equal distributions of component are on accommodation groove；When installation,
Mounting base 1 is fixed, while dropproof component 4 being mounted in accommodating hole, the correspondence of cover board 5 is then mounted on accommodation groove
On, locking component 3 is mounted on top cover 2, top cover 2 is then pushed down into dropproof vertical bar 42, is located at dropproof vertical bar 42 and holds
It sets in hole, while the lid of top cover 2 closes on cover board 5, axis 31 is then promoted to screw thread by screwing tool and is screwed, drive is tiltedly carved
Axis 32 moves down, and tiltedly carves axis 32 and four locking rods 33 is driven to stretch out, and protrude into the lower section of cover board 5, to realize locking top cover 2；And
When needing to open top cover 2, reversed rotary screwing thread promotes axis 31, withdraws four locking rods 33, until locking rod 33 leaves cover board 5
Lower section, top cover 2 then away is taken 2 pull-up of top cover by corresponding tool, after taking top cover 2 away, at this moment dropproof 42 nothing of vertical bar
Top cover 2 is pushed down, and under the elastic force effect of the first spring 41, dropproof vertical bar 42 is stretched out out of accommodating hole, thus in accommodation groove
Four Bian Shangjun are extended with dropproof vertical bar 42, can effectively remind passerby, play a warning role, and prevent under people's back drop, reduce wind
Danger, simultaneously because the elastic force of the first spring 41 acts on, when carrying out 2 replacement operation of top cover, dropproof vertical bar 42 can be provided upwards
Lifting force, the more conducively pull-up of top cover 2 is further conveniently replaceable top cover 2.
The present embodiment is realized by setting locking component 3 locks top cover 2, can effectively prevent top cover 2 and is tampered or top cover 2
It loosens, while can prevent top cover 2 from being washed open under rainstorm weather by water flow；And when taking top cover 2 away or water flow washes top cover 2 open, prevent
Fall vertical bar 42 to pop up out of accommodating hole automatically under the elastic force effect of the first spring 41, plays warning effect, effectively prompting road
People avoids passerby accidentally under back drop, substantially reduces risk；Especially when there is a large amount of ponding, the dropproof vertical bar of pop-up
42 can be shown that herein without the lid conjunction of top cover 2, and passerby or driver is reminded to take a devious route.
In the present embodiment, it is preferable that be respectively provided with three dropproof components 4, the lock on four sides of accommodation groove
Only one end of bar 33 carves axis 32 by pin shaft and tiltedly hingedly, and structure is more flexible.
As shown in figure 5, further, the other end of the locking rod 33 is provided on the basis of based on the above embodiment
Step 331, when work, rotary screwing thread, which promotes axis 31, stretches out locking rod 33, and the step 331 on locking rod 33 is made to stick on cover board
Top cover 2 is lockked to realize in 5 lower section, and structure is more firm.
As shown in figure 4, further, the top cover 2 is additionally provided with four third connections on the basis of based on the above embodiment
Ear 22, four third engaging lugs 22 are in cross distribution, are threaded with annulus jacking block 34 on the locking rod 33, described
Successively activity passes through third engaging lug 22, the first engaging lug 21 to the other end of locking rod 33, and the is arranged on the locking rod 33
Two springs 35, the second spring 35 is between third engaging lug 22 and annulus jacking block 34；Specifically, second spring 35 passes through
Elastic force makes locking rod 33 remain out the trend of stretching always, and top cover 2 is kept to be in locking-in state, avoids screw thread from promoting axis 31 and revolves
It twists not in place or locking rod 33 and jitter phenomenon occurs, and cause to fail to lock top cover 2 jail, further ensure that top cover 2 is in lock
Tight state, structure are more firm, safe.
As shown in fig. 6, further, one end of the dropproof vertical bar 42 is equipped on the basis of based on the above embodiment
One end of circular hole, first spring 41 is fixed in circular hole, and when taking top cover 2 away, the first spring 41 is by dropproof vertical bar 42
Pop-up, to play a warning role, dropproof vertical bar 42 is fixedly connected with the first spring 41, avoids dropproof vertical bar 42 because of elastic force
It is excessive, it is integrally popped up out of accommodating hole, and cause to serve as a warning, further ensure the warning of dropproof vertical bar 42
Effect, structure are more reliable.
As shown in Figure 1, further include dustproof cover 6 further on the basis of based on the above embodiment, 2 center of top cover
Equipped with cover slot, the cover slot is connected to threaded hole, and the lid of dustproof cover 6 closes in cover slot；Specifically, it is promoted by rotary screwing thread
After axis 31 locks top cover 2, dustproof cover 6 is covered, avoids accumulation dust, soil or sandstone, and is unfavorable for rotary screwing thread and promotes axis
31, when needing replacing top cover 2, dustproof cover 6 is opened, rotary screwing thread is then carried out and promotes the opening top cover 2 of axis 31.
The above is only a preferred embodiment of the invention, therefore all according to structure described in present patent application range
It makes, the equivalent change or modification that feature and principle are done, in the protection scope of present patent application.
