Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example 1: referring to fig. 1, the manhole cover lock disclosed by the invention comprises a bottom plate 1, wherein the shape of the bottom plate 1 is like a U shape. The bottom plate 1 is provided with a lock core 22, a lock core column 21 and a lock core seat 2 coaxially from top to bottom in sequence. The lock cylinder seat 2 is fixed on the bottom plate 1, the lock cylinder 21 is rotatably arranged on the lock cylinder seat 2, and the lock cylinder 22 is fixed on the lock cylinder 21. The upper end of lock core 22 is provided with the curved lockhole of taking the curved surface arc, and this lockhole interpolation has the key 3 of adaptation, and key 3 and lockhole adaptation prevent that the well lid from opening at will, improve its theftproof security. The shape of the curved arc-shaped lockhole can be diversified, and the unconventional shape is preferably adopted, so that a key matched with the lockhole is difficult to find in daily life, the safety of the manhole cover lock is improved, and the anti-copy function of the key is improved.

The key 3 can be rotated to drive the lock cylinder 22 to rotate, and when the lock cylinder 22 rotates, the lock cylinder 21 is driven to synchronously rotate. The lock core 22, the lock core column 21 and the lock core seat 2 are manufactured separately, which is beneficial to saving cost and is convenient for production and processing.

Referring to fig. 1, a shifting piece 5 is fixedly connected to the outer side wall of the lock cylinder 21, and an arc-shaped hole 51 is formed in the shifting piece 5. The bottom plate 1 is provided with a latch piece 4, the latch piece 4 is positioned on the movement stroke of the plectrum 5, and the latch piece 4 can be driven to move when the plectrum 5 rotates.

Specifically, referring to fig. 2, the latch member 4 includes a latch base 41, a latch 42, and a set screw 43. The bolt seat 41 is fixed on the bottom plate 1, the bolt 42 is arranged in the bolt seat 41 in a sliding mode, and the limiting screw 43 is fixed at one end of the bolt 42. The bolt seat 41 is provided with a limiting hole, the limiting screw 43 sequentially penetrates out of the limiting hole and the arc-shaped hole 51, and the nut of the limiting screw 43 is positioned on the upper surface of the arc-shaped plate. When the shifting piece 5 rotates, the limiting screw 43 is driven to move in the arc-shaped hole 51, and the bolt 42 is further pushed to extend out of the bolt seat 41 or retract into the bolt 42 seat 41.

Referring to fig. 2, in order to limit the extension of the plug pin 42 and improve the locking efficiency of the manhole cover lock, an expansion rod 44 is movably arranged in the plug pin seat 41, one end of the expansion rod 44 is coaxially and fixedly connected with one end of the plug pin 42 close to a limit screw 43, and the diameter of the expansion rod 44 is smaller than that of the plug pin 42. One end of the telescopic rod 44 penetrating out of the bolt seat 41 is connected with a limit nut 45 through threads. When the end face of the limit nut 45 is abutted against the end face of the bolt seat 41, the bolt 42 extends out of the bolt seat 41 and is abutted against the inner side wall of the walling crib 6, and the anti-theft effect is achieved.

Referring to fig. 2, in order to limit the retraction of the latch 42, a limit boss 411 abutting against an end surface of the latch 42 is provided inside one end of the latch base 41 away from the latch 42. When the tip of bolt 42 contradicts with spacing boss 411, in bolt 42 withdrawal bolt seat 41, bolt 42 did not support with the inside wall butt of walling crib 6 this moment, made things convenient for the well lid to open.

Example 2: referring to fig. 4, an intelligent safety well lid, including walling crib 6 and lid 7, one side of walling crib 6 is articulated with lid 7 through hinge structure 9, is provided with the manhole cover lock among embodiment 1 on the inside wall of lid 7, offers on the lid 7 to supply key 3 male key hole. The manhole ring 6 and the cover body 7 are made of nodular cast iron, and the outer walls of the manhole ring 6 and the cover body 7 are subjected to plastic spraying treatment, so that the physical properties of the manhole ring 6 and the cover body 7 can be improved, the anticorrosive effect is achieved, and the service lives of the manhole ring 6 and the cover body 7 are prolonged.

Referring to fig. 5, the hinge structure 9 includes an arc-shaped connector 91, a pin 92, and a cover plate 93. Waist-shaped hole 62 is opened on the inside wall of walling crib 6, waist-shaped hole 62 and through screw fixedly connected with flat pad are passed to the one end of arc connecting piece 91, the other end of arc connecting piece 91 and perpendicular fixed connection of round pin 92. The cover plate 93 is fixedly arranged on the cover body 7, a sliding groove 931 for sliding the pin 92 is arranged on the cover plate 93, and screws respectively abutted against two ends of the pin 92 are fixedly connected to the cover plate 93. The hinge structure 9 enables the maximum opening angle of the cover body 7 to be 120-160 degrees, when the cover body 7 is completely opened, the cover body 7 does not touch the ground, so that the cover body 7 is not easy to injure the feet of workers, and the safety is improved. The arrangement of the waist-shaped hole 62 enables the cover body 7 to be turned over only when opened, and the cover body 7 is not prone to transverse shaking, so that the cover body 7 is more stable when opened.

Referring to fig. 3, when the cover 7 is closed, the inner protrusion of the cover 7 contacts the inner side of the well ring 6, and when the cover 7 is pressed, such as a car, a pedestrian, etc., the cover 7 is liable to generate vibration or noise. Thus, several washers 61 are provided in the circumferential direction of the inner top wall of the well ring 6. The gasket 61 can reduce the vibration or noise generated when the cover 7 is subjected to pressure, and improve the service life of the cover 7.

Referring to fig. 3, in order to monitor the opening or closing of the cover 7, a dynamic reminder 8 for internet of things is fixedly connected to the inner side wall of the cover 7 through bolts.

The implementation principle of the embodiment is as follows: when the well lid is installed, the well ring 6 is fixed on the cement seat through a plurality of fixing nails, so that thieves can be prevented from prying the well ring away together, and the stability and firmness of well lid installation can be improved. Preferably, 3-5 fixing nails are arranged, and the fixing nails are uniformly distributed at the top of the walling crib and are fixed with the cement seat. Well lid is closed back, insert key 3 from the key hole on lid 7, make key 3 insert in the lock core 22, rotate key 3, make lock core 22 rotate, thereby drive lock core post 21 and rotate, when lock core post 21 rotates, drive plectrum 5 and rotate, 5 pivoted in-process of plectrum, drive spacing screw 43 removes in arc hole 51, and then drive bolt 42 and stretch out bolt seat 41, bolt 42 moves the below to the inside wall of walling crib 6, the terminal surface of until stop nut 45 is contradicted with the terminal surface of bolt seat 41, then extract key 3 from lock core 22, the well lid is difficult to be opened, the theftproof performance is good.

When the well lid needs to be opened, insert key 3 into lock core 22 again, reverse rotation lock core 22 for bolt 42 retracts, and at this moment, bolt 42 breaks away from the below of the inside wall of walling crib 6, and the tip of bolt 42 is contradicted with spacing boss 411, and at this moment, can open lid 7.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
