Detailed Description

The technical solution of the present invention is further explained with reference to the drawings and the embodiments.

As shown in fig. 1-4, in order to simplify the opening mode of the anti-theft manhole cover. The utility model provides a theftproof well lid convenient to maintainer opens, include well seat 1 and articulate apron 2 on well seat 1, evenly be provided with along well seat 1's radial slip latch segment 5 around the axis in the well seat 1, be provided with supporting spring between the inner wall of latch segment 5 and well seat 1, latch segment 5's top is provided with the inclined plane, 2 bottom surfaces of apron are provided with the plug 8 that is used for promoting latch segment 5 compression supporting spring, horizontal bulge and opening that are used for the lock are seted up respectively to plug 8's bottom and latch segment 5 middle part, plug 8 is provided with the drive of the lock axle 13 that opens of counter bore through the top and unifies the rotation, the lock axle 13 that unlocks rotates and sets up on apron 2.

After the well seat 1 is fixed, the cover plate 2 is covered, the plug 8 on the bottom surface of the cover plate 2 is in contact with the locking block 5 in the process of rotating along with the cover plate 2, the plug 8 pushes the locking block 5 to slide along the axis of the well seat 1 through the inclined surface on the top of the locking block 5, so that the locking block 5 compresses the supporting spring, along with the downward movement of the plug 8, when the horizontal bulge on the bottom end of the plug 8 and the opening in the middle of the locking block 5 are at the same height, the supporting spring pushes the locking block 5 to reversely slide, so that the horizontal bulge on the bottom end of the plug 8 enters the opening in the middle of the locking block 5, the buckling between the plug 8 and the locking block 5 is realized, and further the fixing of the cover plate 2 is realized; and supporting spring still is in the state of compressed this moment, and apron 2 is fixed through four 8 cooperation latch segments 5 of four plugs for 2 are whole to be caught on by even, have promoted the theftproof performance of well lid.

When the maintenance personnel open apron 2, through inserting the tip of key in the triangle-shaped counter bore at unlocking axle 13 top, maintenance personnel drive unlocking axle 13 through the key and rotate for plug 8 rotates, and plug 8 and latch segment 5 separation can be opened apron 2, realize opening of well lid.

As shown in fig. 2-3, to avoid foreign objects from clogging the counterbore at the top end of the unlocking shaft 13. The middle of the cover plate 2 is coaxially provided with a stepped mounting hole, the unlocking shaft 13 is rotatably arranged in the mounting hole, and the cover plate 2 is provided with a locking plate 11 for covering the mounting hole through a connecting bolt 12. Cover the mounting hole of unlocking shaft 13 through jam plate 11 for in impurity can't get into jam plate 11, avoid causing the burden to maintainer's unblanking.

As shown in fig. 1-4, to facilitate the replacement of the plug 8 after opening the cover 2. Plug 8 through connecting rod 7 fixed connection in on the unlocking shaft 13, the bottom surface of apron 2 is provided with the carriage 9 that is used for supporting connecting rod 7, the inside both sides wall of carriage 9 is connected with the both sides wall of connecting rod 7 through reset spring 10 respectively. The bottom end of the unlocking shaft 13 is coaxially connected with a connecting block 6, and the connecting rod 7 is connected to the connecting block 6; when a maintainer opens the cover plate 2, the rotation of the connecting rod 7 can compress the return spring 10 on one side of the connecting rod and simultaneously pull up the return spring 10 on the other side of the connecting rod, after the cover plate 2 is opened, the key is loosened, and the return of the connecting rod 7 can be realized through the return springs 10 on the two sides of the connecting rod 7; and the return spring 10 is added to increase the resistance of opening the cover plate 2, so that the unlocking shaft 13 is difficult to rotate when a matched key is not used, and the anti-theft performance of the well cover is further improved.

As shown in fig. 1-3, to achieve the mounting of the locking block 5 and the supporting spring. The fixed installing frame 3 that is provided with of 1 inner wall of well seat, be provided with slide bar 4 in the installing frame 3, latch segment 5 slides and sets up on slide bar 4, supporting spring locates on slide bar 4, the lateral wall of latch segment 5 with the inside wall laminating of installing frame 3. The locking block 5 is supported by the sliding rod 4, and the locking block 5 is limited by the mounting frame 3, so that the locking block 5 can only slide along the axial direction of the sliding rod 4; when the locking block 5 is pushed by the plug 8, the locking block 5 compresses the supporting spring.

As shown in fig. 1-3, the locking block 5 is moved to achieve smooth pushing of the plug 8. The bottom end of the plug 8 is provided with an inclined plane, and the slope of the inclined plane at the bottom end of the plug 8 is greater than that of the inclined plane at the top end of the locking block 5. Through setting up the inclined plane in the bottom of plug 8, the inclined plane extends to horizontal protruding department, and horizontal protruding removal that can be smooth is to the opening part at 5 middle parts of latch segment, and then realizes the lock between plug 8 and the latch segment 5.

As shown in fig. 1 to 3, in order to prevent the cover 2 from being unable to be opened after the cover 2 is deformed by pressure. The opening of the horizontal protrusion in the middle of the locking block 5 for accommodating the bottom end of the plug 8 is positioned above the mounting frame 3. Through the setting to position between the horizontal bulge of 8 bottoms of plugs and the installing frame 3 for when apron 2 appears deforming because of long-term pressurized, the plug 8 of height-reducing is difficult to contact with installing frame 3.
