Abstract

The utility model discloses a manhole cover arranged on a manhole cover support with periphery raised. The center of the manhole cover is provided with a manhole air hole. The manhole cover is characterized in that a handle lever is arranged on one side of the manhole air hole, one end of the handle lever is connected with a pull ring grip, the other end of the handle lever is connected with a rotating shaft, and the rotating shaft is disposed at the end of the manhole cover support. When the manhole cover is in use, no additional uncovering tool is needed; when the manhole adheres at a joint and is difficult to open and especially in winter, ice freezes in the joint of the manhole cover, the manhole cover can be easily opened by leverage of the handle ever and the manhole cover support.

Description

A kind of well lid

Technical field

The utility model relates to a kind of well lid, belongs to mechanical field.

Background technology

In routine work or upkeep operation, servant's well carries out mechanical water meter and copies number or keep in repair flow meter while popping one's head in, must carry the instruments such as iron hook of opening people's well, especially at well lid, do not open for a long time, gap is dead by dust plug, or the moisture of people in winter down-hole freezes well lid gap, well lid is sticked together cannot smooth opening, to attendant, has brought inconvenience.

Summary of the invention

In order to overcome above-mentioned deficiency, the utility model provides a kind of well lid, arranges one for opening the handle of well lid in well lid, solves the trouble that each servant's well operations need carry the instruments such as iron hook, and when well lid sticks together in the winter time, this built-in handle can also play the effect of crowbar.

The technical solution adopted in the utility model is: a kind of well lid, well lid is positioned in the well lid holder of peripheral projection, well lid central authorities are provided with people's well air-vent, it is characterized in that: the side at described air-vent is provided with handlebar, handlebar one end is connected with draw ring handle, other end connection rotating shaft, rotating shaft is arranged on the end of well lid holder.

Described handlebar can rotate 0 ~ 90 ° along rotating shaft.

Described handlebar is rectangular structure, is positioned at the radial direction of well lid, is embedded in well lid.

Well lid of the present utility model is on the basis of common well lid, has embedded a monocycle handle, while so just having saved each servant's well operations, must carry the trouble of opening well lid instrument.Built-in handle is embedded in well lid when not using, and built-in handle and the material of handlebar are identical with the material of well lid.

On-the-spot while needing lower well operations, from well lid, rout up handle, take the rotating shaft of handle as axle center by handle clockwisepull-up, just can open well lid; Do not open for a long time running into well lid, gap is dead by dust plug, or the moisture of people in winter down-hole freezes while being difficult for opening well lid gap, handle can be pulled out, and take the edge of well lid holder is fulcrum, and handlebar is lever, clockwiseoutwards prize well lid, make well lid loosening, thereby smoothly well lid is opened.

The well lid that the utility model provides, the beneficial effect bringing:

(1) drive a well while covering, do not need to carry in addition cover opening tool;

(2) when the adhesion of well lid gap is not easy to open, especially in the winter time, when well lid gap freezes, the crowbar principle of utilizing handlebar and well lid holder to form is easily opened well lid.

Below in conjunction with drawings and Examples, the utility model is described further.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model well lid.

Fig. 2 is the top view (analysing and observe) of Fig. 1.

Fig. 3 is the use state diagram of the utility model well lid.

In figure, 1 is well lid holder, and 2 is well lid, and 3 is handlebar, and 4 is handle, and 5 is air-vent, and 6 is rotating shaft.

The specific embodiment

Embodiment:

As shown in Figure 1, 2, a kind of well lid, well lid 2 is positioned in the well lid holder 1 of peripheral projection, well lid 2 central authorities are provided with people's well air-vent 5, it is characterized in that: the side at described air-vent 5 is provided with handlebar 3, handlebar 3 one end are connected with draw ring handle 4, other end connection rotating shaft 6, and rotating shaft 6 is arranged on the end of well lid holder 1.

As shown in Figure 3, described handlebar 3 can be along 0 ~ 90 ° of rotating shaft 6 rotation.

Described handlebar is rectangular structure, is positioned at the radial direction of well lid, is embedded in well lid.The material of handlebar is identical with the material of well lid.

Concrete method of operating is:

Built-in handle is embedded in well lid when not using.On-the-spot while needing lower well operations, from well lid, rout up handle, take the rotating shaft of handle as axle center by the clockwise pull-up of handle, just well lid can be opened; When running into the situation that well lid do not open for a long time, handle can be pulled out, take the edge of well lid holder is fulcrum, and handlebar is lever, and clockwise direction prizes well lid outward, makes well lid loosening, thereby smoothly well lid is opened.

Claims
