Detailed description of the invention
As shown in Fig. 1,2,3,4,5,6,7,8, anti-stealing manhole cover, comprise well seat 1, be arranged on the well lid 2 of well seat 1 mouth position, the side of described well lid 2 is provided with a cannelure 3, the mouth inner wall circumference of described well seat 1 is equidistantly provided with four supporting seats 4, on described well lid 2, circumference is equidistantly provided with four gap 5, four described gap 5 are corresponding with four supporting seats 4, when well lid opened by needs time, only need rotating well cover to the position of gap supporting seat in May 4 correspondence, then mention straight up.The upper surface of described well lid 2 is provided with recess 6, and the setting of this recess 6 mainly conveniently rotating well cover 2, when concrete operations, needs both hands to be buckled in two recesses 6 simultaneously, then rotate.
The centre of described well lid 2 is provided with the through hole 9 of a square structure, a key 10 is fitted with in described through hole 9, described key 10 upper end is provided with handle 12, the centre of described well lid 2 is provided with circular hole 13, the side of described circular hole 13 is arc surfaced structure, the side of described handle 12 is also arc surfaced structure, the setting of this key handle, can be that the handle 12 of key is just in time buckled in circular hole 13, its upper surface is just in time concordant with the upper surface of upper cover body 21, is at this time just not easy key to take out.Can play antitheft effect, the theme position of key adopts square structure in addition, even if go to prize handle 12 and the seam crossing of circular hole 13 by other instrument like this, is also not easy handle 12 to take out.
Based on the above, described well lid 2 is made up of upper cover body 21 and lower cover 22, described cannelure 3 is arranged on lower cover 22 side, top edge and the upper cover body 21 of described cannelure 3 are set with, the top edge of described cannelure 3 slides up and down in upper cover body 21, and the inner surface of described upper cover body 21 is provided with four slideways 7, and what the top edge of described cannelure 3 was corresponding is provided with four slide blocks 8, have employed double-deck structure, mainly in order to set up the jacking mechanism of the handle 12 of key 10.Double-deck setting in addition, most important is that lower cover 22 also can be played a supporting role when upper cover body 21 is pulverized by automobile time, though have certain distance between lower cover 22 and upper cover body 21, but substantially can ensure the smooth of road surface, and the safety on road surface.
The lower limb diameter of described cannelure 3 is identical with the external diameter of upper cover body 21, and the height of described cannelure 3 is greater than the thickness of four supporting seats 4;
Described key 10 is contacted upper cover body 21 and lower cover 22 successively, the end that described key 10 passes lower cover 22 is provided with disk 11, one can be formed between disk 11 and handle 12 limit, upper cover body 21 and lower cover 22 can be serially connected like this, especially the weight ratio of lower cover 22 is comparatively large, therefore, when needs are by whole for inspection well cover mentioning time, disk 11 can support lower cover 22, also can not rock, and is therefore convenient to upper cover body and lower cover to take out simultaneously.In addition, main, when well lid 2 needs to rotate time, upwards lifted by the handle 12 of key 10, then rotate.
Based on the above, four described supporting seat 4 upper surfaces are provided with protruding 17, on corresponding cannelure 3, end face is provided with deep-slotted chip breaker 13, described projection 17 in deep-slotted chip breaker 13 along the central rotation of well lid 2, described deep-slotted chip breaker 13 is made up of the deep-slotted chip breaker 1 mutually docked and deep-slotted chip breaker 2 15, the bottom surface of described deep-slotted chip breaker 1 is slope structure, and described lower cover 22 upper surface center circumferential is furnished with protruding 1.Above structure, in time rotating key 10 by handle 12, under the drive of key 10, well lid 2 will rotate, like this, protruding 17 will move along deep-slotted chip breaker 1, the position moving to deep-slotted chip breaker 2 15 from the lowest part of deep-slotted chip breaker 1 slowly, at this time, lower cover 22 will move upward along key 10, then protruding 1 will promote handle 17 and move upward, handle 17 just can expose well lid upper surface, then handle 12 is caught upwards to mention, the upper surface of disk 11 is contacted with the bottom surface of lower cover 22, then swing handle 12, drive well lid rotates, thus make protruding 17 to move along deep-slotted chip breaker 2 15, make supporting seat 4 move to the position of gap 5 always, then upwards well lid is mentioned by handle 12, both opening of well lid can be realized.
Based on the above, described projection 1 is at least three, circumference equidistant placement, the setting of the number of protruding 1, three and four can, as long as it is even to exert oneself when upwards jack-up handle 12.
Based on the above, described projection 17 is arranged on the outer end of supporting seat 4, if also have certain distance between protruding 17 and the end of supporting seat 4, so when well lid 2 rotates time, end then easy and annular 3 direct friction of supporting seat 4, thus the movement of impact protruding 17.
Based on the above, the inner top surface of described upper cover body 21 is provided with crash sensor 23, control chip 24 and wireless communications chips 25, and described control chip 24 is connected with crash sensor 23, is connected again with wireless communications chips 25 simultaneously.The setting of crash sensor 23 mainly considers that the loss of present most inspection well cover is all damage by strong violence or steal, inspection well cover is directly opened by such as direct hammer or other crowbar, then steal, but the inspection well cover that the utility model relates to itself must be adopt the mode of rotating to open, adopt its mode, such as adopt the mode pried open, pry open from side, or centre is pried open, all do not open, and can inspection well cover be damaged, therefore need to arrange crash sensor 23 on inspection well cover, once have employed the mode that violence damages inspection well cover, so crash sensor 23 will send signal, control chip 24 receives signal simultaneously, control wireless communications chips 25 and send wireless signal, just can monitor.In addition, according to the situation of reality, control chip 24 and wireless communications chips 25 are arranged on lower cover 22, can prevent because violence is broken damage control chip 24 and wireless communications chips 25 on the one hand, also the intensity that signal passes well lid can be increased on the other hand, if be arranged on inspection shaft wall, the transmission of signal so can be affected because of the thickness problem of inspection well cover.
