Abstract

The utility model relates to a manhole, in particular to a manhole used for the construction and maintenance of specialized equipments buried underground. Composing of an iron chain, an hinge and a lock, the current burglarproof manhole has a complex structure, wherein the burglarproof metal components tends to get rusty so as not be removed, the manhole lid is hard to open so as to constrain maintenance and the manhole lid is easily stolen when the manhole lid is opened to put aside. The utility model comprises a manhole pedestal and a manhole lid above the manhole pedestal where the manhole lid is arranged on inner surrounding sidesteps, wherein protrudent axis joints which is lower to the underside of manhole are arranged on both sides of the manhole lid and the material is taken to form the space, in whose both side walls an axis joint is fitted into the crossing runner in which a counterbore is provided to put the axis joint, matching the axis joint on the inner surrounding sidesteps of the manhole pedestal. When the utility model is used by the concerted work between the axis joint and the runner in the manhole, the manhole lid is turned to open and closed, which also can warn the passerby to dodge the manhole and still be removed even though the manhole lid gets rusty.

Description

A kind of manhole

[technical field]

The utility model relates to manhole, particularly a kind ofly often buries the manhole that the special equipment Construction and Maintenance are used underground to underground.

[background technology]

Common manhole is made up of well seat and the well lid on it, and for inspection is embedded in underground various cable facilities, well lid need often be opened, and is stolen easily, causes road " opening ", and particularly the manhole multidigit has major hidden danger to pedestrains safety on the sidewalk.Existing antitheft manhole with iron chains, hinge or lock head structure, complex structure, the metalwork that plays antitheft effect easily gets rusty stuck, makes well lid be difficult to open, and maintenance is inconvenient; All can remove after well lid is opened, it is also stolen easily to be placed on the roadside.

[utility model content]

Goal of the invention of the present utility model is to overcome the fault of construction that existing antitheft manhole exists, and also is difficult for stuck manhole after a kind of getting rusty is provided, and manhole cover can be erected at the manhole that cloudy well head plays reminding effect after opening.

For achieving the above object, the technical solution of the utility model is: a kind of manhole, comprise well seat and the well lid on it, well lid is placed on the inboard periphery step of well seat, it is characterized in that described well lid both sides are provided with the axis part of outside protrusion, described axis part is lower than the manhole cover bottom surface, and the inboard periphery step of well seat corresponding position goes to expect that the back forms the neutral gear corresponding with the axis part, have the horizontal chute that cooperates with the axis part on the neutral gear sidewall, be provided with one in the described chute and lay the counterbore of axis part.Axis part and the chute of well lid by evagination cooperates and is installed on the well seat, and well lid can rotating opening, can not break away from the manhole seat again; The slide groove portion space is big, though get rusty also be difficult for stuck.Wherein when the axis part was arranged in counterbore, well lid and well seat flushed placement; Upwards mention well lid, make the axis part when counterbore moves to the horizontal chute, well lid can rotate unlatching relative to the manhole seat, and well lid leans against on the well seat after opening, and reminds the pedestrian to note dodging, and also is difficult for losing.

Axis part described in the utility model comprises and is located on the manhole cover bottom surface with the semicircle seat of its one and is through pin member on the semicircle seat.By pin member slip effect in chute manhole cover is erected; Semicircle seat and manhole cover are structure as a whole, and strengthen the pin member installation strength, guarantee the reliability that connects.

Pin member described in the utility model is to penetrate the bolt that welds on the semicircle seat, and screw rod one end that directly utilizes bolt is convenient to make and install as pin member.

Well lid described in the utility model is made up of two double cover plates, the well lid both side ends is provided with four axis parts of outwards protruding altogether, two double cover plates constitute well lid, the closure or openness well lid is similar to the switching window, need insert open hole with special tool from the centre, be used on the bigger manhole of area, satisfy various use needs.

The utility model cooperates at the chute that is provided with on the well lid on axis part and the manhole seat, realizes that well lid rotates closure or openness and sets level, and can be erected at unlimited well head after well lid is opened, and reminds the pedestrian to note dodging, through long-time use get rusty also be difficult for stuck.

Below in conjunction with the description of drawings and the specific embodiment the utility model is described further.

[description of drawings]

Fig. 1 is embodiment 1 a manhole structural representation.

Fig. 2 is embodiment 2 manhole structural representations.

Among the figure: 1. well seat, 2. well lid, 2-1. semicircle seat, 3. open hole, 4. axis part, 5. chute, 5-1. counterbore, 6. pin member.

[specific embodiment]

Embodiment 1 as shown in Figure 1, a kind of manhole comprises well seat 1, lay on it the band open hole 3 well lid 2; The same end in well lid both sides is provided with the axis part 4 of outside protrusion, open hole 3 is positioned at the well lid other end, the axis part constitutes with the semicircle seat 2-1 of its one and the pin member 6 that is through on the semicircle seat by being located on manhole cover 2 bottom surfaces, and pin member is to penetrate the bolt that semicircle seat 2-1 goes up welding; The inboard periphery step of well seat corresponding position is gone to expect to form two neutral gears corresponding with the semicircle seat, has the horizontal chute 5 that cooperates with the bolt end on the neutral gear sidewall, is provided with a counterbore 5-1 who lays bolt in the described chute.When bolt screw rod one end was arranged in counterbore, well lid and well seat flushed during use; When maintenance need be opened well lid, upwards mention manhole cover from open hole, bolt is moved out to from counterbore in the horizontal chute, manhole cover can rotate unlatching relative to the manhole seat, manhole cover leans against on the manhole seat after opening, look far into the distance, manhole cover is promptly erect and is leaned against on the manhole seat, both has been difficult for losing causing easily that also the pedestrian notes and dodges.

Embodiment 2 as shown in Figure 2, difference from Example 1 is that well lid 2 is made up of two double cover plates, the well lid both side ends is provided with four axis parts 4 of outwards protruding altogether, also be provided with the chute 5 of four correspondences on the well seat, wherein open hole 3 is positioned at well lid center line both sides, and all the other structures are identical with embodiment 1.In the use, the closure or openness of well lid are similar to the switching window, insert open hole from the centre with special tool, are used on the bigger manhole of area.
