Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is The part of the embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill people The every other embodiment that member is obtained on the premise of creative work is not made, belongs to the scope of protection of the invention.
In the description of the invention, it is necessary to illustrate, unless otherwise clearly defined and limited, term " installation ", " phase Even ", " connection " should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected, or be integrally connected；Can To be mechanical connection or electrical connection；Can be joined directly together, can also be indirectly connected by intermediary, Ke Yishi The connection of two element internals.For the ordinary skill in the art, with concrete condition above-mentioned term can be understood at this Concrete meaning in invention.
In addition, in the description of the invention, unless otherwise indicated, " multiple ", " more ", " multigroup " be meant that two or Two or more, " several ", " some ", " some groups " are meant that one or more.
Embodiment one
As shown in figure 1, the inspection shaft that the present embodiment provides, including support body 1 and well lid 2, well lid 2 lead to provided with screw thread Hole 21, the upper end of support body 1 are provided with the screwed hole 13 being engaged with tapped through hole 21, and tapped through hole 21 passes through with screwed hole 13 Bolt 3 is connected, and well lid 2 is connected with the upper end of support body 1.
The inspection shaft of the present invention is coordinated with the tapped through hole of well lid and the screwed hole of support body respectively using bolt, by well Lid is fixed in support body, and compared with the iron chains theft-prevention structure of prior art, bolt theft-prevention structure of the invention is with more spirit Activity, specific instrument should be used in installation or removal by bolt precession or screws out screwed hole, improves anti-theft and anti-losing Performance, and being connected well lid with support body by bolt, it also avoid well lid trampled by pedestrian rolled with vehicle when, well Lid is moved relative to support body, and well lid hits support body and made a noise.
Wherein, bolt 3 is provided with special shaped screw bolt cap 31, the upper surface of special shaped screw bolt cap 31 and well lid 2.Different in nature bolt Cap, which screws, to be inserted in outside bolt, is compressed with the upper surface of well lid, keeps fixing, and special shaped screw bolt cap can be polygon, circular arc or more Side shape and circular combination, the jacket casing spanner that need to customize the inner cylinder of respective shapes screws, therefore more adds the anti-of well lid Steal anti-lost performance.
Wherein, the upper surface of well lid 2 is provided with what shape was engaged with special shaped screw bolt cap 31 in the edge of tapped through hole 21 Groove 22, special shaped screw bolt cap 31 are located in groove 22.Special shaped screw bolt cap is screwed as after bolt, fallen into the groove on well lid, is protected The smooth of well lid upper surface is held, avoids and forms road barrier because of the protrusion of heterotypic bolt cap, in addition, groove and special shaped screw bolt The shape of cap is engaged, and be further limit the shape for the instrument for screwing out nuts, is also increased the anti-theft and anti-losing of well lid Performance.
Further, support body 1 includes bottom support bracket 11, and the upper end inwall of bottom support bracket 11 extends internally provided with level The first supporting table 111.For there was only the support body of one layer of bottom support bracket, the first supporting table is used to set up well lid, now well The lower surface of lid is erected on the upper surface of the first supporting table, and for the support body of multilayer, the first supporting table is used to set up other Layer bearing.
Wherein, the lower surface of well lid 2 is erected on the upper surface of the first supporting table 111, and screwed hole 13 is located at the first supporting table On 111.When the first supporting table is used to set up well lid, now the lower surface of well lid is erected on the upper surface of the first supporting table, position It is preferably through hole in the screwed hole in the first supporting table, makes the first supporting table completely and bolt connection, increases bolt and bottom The tightness of bearing connection.
In addition, tapped through hole 21 is multiple, and it is uniformly distributed circumferentially.It is multiple to be uniformly distributed circumferentially at well lid edge Tapped through hole, in bolt connection, it is ensured that well lid and support body be mutually fastenedly connected be more uniformly stressed it is scattered, Add the quantity of theft-prevention structure.
Embodiment two
The difference of the present embodiment and above-described embodiment one is that as shown in Figures 2 and 3, support body 1 also includes lifting branch Seat 12, lifting bearing 12 is connected with bottom support bracket 11, and the lower surface for lifting bearing 12 is erected on the upper table of the first supporting table 111 Face.The lifting bearing for increasing support body height is erected with the present embodiment in first supporting table of bottom support bracket, now The lower surface of lifting bearing is erected on the upper surface of the first supporting table.
Wherein, the inwall for lifting bearing 12 is provided with horizontal the second supporting table 121 to extend internally.Second supporting table is the same as first Supporting table acts on identical, the requirement for height according to practice of construction for support body, and the second supporting table can be used for setting up well lid, Available for setting up other layer of bearing.
Wherein, the lower surface of well lid 2 is erected on the upper surface of the second supporting table 121.It is used to set up well in the second supporting table Gai Shi, now the lower surface of well lid be erected on the upper surface of the second supporting table, the screwed hole in the second supporting table is preferably Through hole, makes the second supporting table completely and bolt connection, increases the tightness that bolt is connected with lifting bearing.
In summary, inspection shaft of the invention using bolt respectively with the tapped through hole of well lid and the screwed hole of support body Coordinate, well lid is fixed in support body, compared with the iron chains theft-prevention structure of prior art, bolt theft-prevention structure of the invention With more flexibility, specific instrument should be used in installation or removal by bolt precession or screws out screwed hole, is improved antitheft Anti-lost performance, and being connected well lid with support body by bolt, it also avoid well lid and trampled and vehicle by pedestrian When rolling, well lid is moved relative to support body, and well lid hits support body and made a noise.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although The present invention is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：It still may be used To be modified to the technical scheme described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic； And these modification or replace, do not make appropriate technical solution essence depart from various embodiments of the present invention technical scheme spirit and Scope.
