Description

A kind of Safety well cover

(1) technical field

This utility model relates to highway articles for use facility technology field, particularly to a kind of Safety well cover.

(2) background technology

In urban construction, because burying and safeguard the needs of underground piping underground in the future, need to arrange blow-off line under road surface Well, gas pipeline well and electric power, communication cable operation well etc., the well lid arranged on the well head of these wells is mostly by cast iron system Make, simple with the attachment structure on wellhead receptacle and ground, run into severe rainwater weather, because impeded drainage is easily rushed by water Walk, bring great potential safety hazard, and anti-theft effect is poor, is usually stolen by unprincipled fellow, seriously jeopardize contact vehicle and pedestrian Life security, also result in highway facilities property waste, become a big hidden danger in city.

(3) summary of the invention

This utility model is in order to make up the deficiencies in the prior art, it is provided that a kind of rational in infrastructure, convenient and practical, be avoided that because of Heavy rain weather well lid is washed away, is avoided stolen Safety well cover, solves problems of the prior art.

This utility model is achieved by the following technical solution:

A kind of Safety well cover, is located at the well lid of wellhead receptacle upper end, is provided with on wellhead receptacle medial wall including wellhead receptacle and lid Female thread, is provided with external screw thread in the outside of well lid, and described well lid is connected with wellhead receptacle inside thread；It is provided with one at the middle part of well lid First groove, sets a central lid at the first groove top lid, and one end of described central lid is hinged with well lid, described central lid The other end is provided with a center cover lock, and described central lid is connected, on the edge, bottom of the first groove with well lid sealing by center cover lock First groove bottom land length direction is provided with a space, and the first groove inner wall side above space connects an elastic spring, institute The one end stating elastic spring is connected with the first groove inner wall, and the other end of described elastic spring connects a slide block, at the end of slide block Portion connects a tilting bar, and the upper end of described tilting bar is connected through space with slide block bottom, and the outside of described tilting bar lower end connects Connect a horizon bar；It is provided with one second groove along wellhead receptacle circumferential direction on wellhead receptacle medial wall below well lid, described second Groove coordinates with horizon bar and is connected.

The beneficial effects of the utility model are: this Safety well cover is by setting the first groove at the middle part of well lid, recessed first Trench bottom sets a space, on the first groove inner wall above space by one elastic spring connect one can in the first groove edge The slide block slided in gap lengths direction, connects a tilting bar passing space, in the outside of tilting bar lower end in the bottom of slide block Connecting one and be inserted into the horizon bar in the second groove, above structure can ensure when placing well lid, promotes elastic spring compression to make Well lid is placed on wellhead receptacle upper end to squatting down, and then unclamps high-tension compression spring, horizontally rotates well lid so that it is inside wellhead receptacle Threaded engagement, during well lid is threadeded with wellhead receptacle rotation, horizon bar gradually rotates along wellhead receptacle inwall and glides also Final downslide is inserted in the second groove, so that firm being stuck on wellhead receptacle of well lid.Fastness is strong, prevents well lid at heavy rain Or float under the External Force Acting of vertical direction or lift, eliminate potential safety hazard.Due to the first groove top lid set one with The central lid of center cover lock, can make other people cannot directly contact slide block, it is to avoid water at ordinary times by central lid dense block on well lid Flat bar and the second groove depart from, even if well lid and wellhead receptacle loosen, because the clamping of horizon bar and the second groove also cannot be opened Well lid, play anti-theft function, it is to avoid property loss.

(4) accompanying drawing explanation

Below in conjunction with the accompanying drawings this utility model is further described.

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the manhole cover structure schematic diagram that in Fig. 1, central lid is opened；

Fig. 3 is to look up structural representation in well.

In figure, 1 wellhead receptacle, 2 well lids, 3 first grooves, 4 central lid, 5 center cover locks, 6 spaces, 7 elastic springs, 8 slide blocks, 9 tilting bars, 10 horizon bars, 11 second grooves.

(5) detailed description of the invention

For the technical characterstic of this programme can be clearly described, below by detailed description of the invention, and combine its accompanying drawing, to this reality It is described in detail with novel.

Embodiment 1

As illustrated in the accompanying drawings from 1 to 3, this Safety well cover includes that wellhead receptacle 1 and lid are located at the well lid 2 of wellhead receptacle 1 upper end, at well head The medial wall of seat 1 upper end is provided with female thread, is provided with external screw thread in the outside of well lid 2, and described well lid 2 and wellhead receptacle 1 pass through spiral shell Stricture of vagina is connected；It is provided with one first groove 3 at the middle part of well lid 2, sets a central lid 4, described central lid 4 in the first groove 3 top cover One end be hinged with well lid 2, the other end of described central lid 4 is provided with a center cover lock 5, and described central lid 4 passes through central lid Lock 5 seals with well lid 2 and is connected, and is provided with a space 6, in space in the bottom of the first groove 3 along the first groove 3 groover rot diameter direction The first groove 3 inwall side above in the of 6 connects an elastic spring 7, and one end of described elastic spring 7 is solid with the first groove 3 inwall Even, the other end of described elastic spring 7 connects a slide block 8, connects a tilting bar 9 in the bottom of slide block 8, described tilting bar 9 Upper end is connected through space 6 with slide block 8 bottom, and the outside of described tilting bar 9 lower end connects a horizon bar 10；Below well lid 2 Wellhead receptacle 1 medial wall on be provided with second groove 11 inserted for horizon bar 10 along wellhead receptacle 1 circumferential direction, described second recessed Groove 11 coordinates with horizon bar 10 and is connected.
