Abstract

The utility model relates to an opening-type manhole cover which is composed of a base, a dead cover and a movable cover. The base and the dead cover are cast to integration, and the movable cover are connected with the base and the dead cover to integration through a pin shaft. The rotation opening can be conducted by using the pin shaft as the shaft. The utility model has the advantages of novel structure, convenience, practicability, low cost, etc. the three parts are connected to integration through the cast connection and the pin shaft connection. The opening-type manhole cover overcomes the disadvantages of separated structure of the original manhole cover and easy to lose, and is the novel manhole cover with active social effect.

Description

The open-type well lid

Open-type well lid described in the utility model is a kind ofly with bearing pin well lid and base to be linked together, and the novel well head that can conveniently open or pipeline opening sealing apparatus.

At present, be used for the well head of town and country, various places, rural area or pipeline opening sealing well lid majority by base and well lid two partly institute forms, two is partly identical and mutual identical by diameter, is not connected as one.In real life, because of mismanagement, the phenomenon that well lid is lost usually appears, well head or pipeline opening are exposed on ground, damage inner facility easily, pedestrian or vehicle are crashed in well head or the pipeline opening accidentally, cause unexpected injury, even great accident takes place.At existing problem in the prior art, a kind of novel open-type well lid of research and design, existing problem is very necessary in the prior art thereby overcome.

In view of existing with topic in the above-mentioned prior art, the purpose of this utility model is a kind of novel structure of design, convenient and practical, with low cost, novel open-type well lid that applicability is strong.The utility model adopts bearing pin jointing type structure, and well lid and base are connected as one, and well lid can bearing pin be that axle rotarily opens, and has overcome the shortcoming that well lid is easily lost, and can be applicable to various places.So the utility model is a kind of convenient and practical novel open-type well lid.

Open-type well lid described in the utility model, its structure partly is made up of base [1], fixed cap [2] and removable cover [3] three; Base [1] is annular, is installed on the exit of pipeline or well; Fixed cap [2] is the smaller part circle, and its diameter is identical with base [1] internal diameter, and camber line edge and base [1] casting is connected as a single entity, and linear edge evenly has the square hole of odontoid, and the side has circular inner hole; Removable cover [3] is large semi-circular, its diameter is identical with base [1] internal diameter, linear edge also evenly has the square hole of odontoid, the side has circular inner hole, when being embedded in base [1], the square hole of its odontoid just matches with the odontoid square hole of fixed cap [2], and the side circular inner hole is just corresponding with the side circular inner hole of fixed cap [2]; Bearing pin [4] is penetrated among the side circular inner hole of the side circular inner hole of fixed cap [2] and removable cover [3], fixed cap [2] and removable cover [3] are connected as one.On the axis of removable cover described in the utility model [3] perpendicular to linear edge, have " ten " font near camber line edge and carry and cover hole [5].Base described in the utility model [1] can be rectangle or square, and when base [1] was rectangle or square, fixed cap [2] and removable cover [3] were rectangle accordingly.

The utility model provides a kind of novel open-type well lid, thereby original well lid and base are divided into two partly, do not connect mutually, in addition radical change of the shortcoming that well lid is lost easily provides a kind of open-type well lid brand-new, bearing pin jointing type structure to society.The utility model is connected as one well lid and base with bearing pin, well lid can rotarily open for axle by bearing pin, its size dimension all with now use well lid identical, has good substituting and safety, be a kind of novel structure, convenient and practical, with low cost, novel open-type well lid that applicability is strong, its large batch of coming into operation will produce positive social benefit.

Four in the total accompanying drawing of the utility model: accompanying drawing 1: open-type well lid vertical view accompanying drawing 2: open-type well lid side A-A sectional view accompanying drawing 3: open-type well lid side B-B view accompanying drawing 4: open-type well lid side C-C sectional view wherein: 1, base 2, fixed cap 3, removable cover 4, bearing pin 5, carry and cover the hole

Specific embodiment of the utility model cylinder iron casts out base [1] and the fixed cap [2] and the removable cover [3] of one as shown in drawings.With tap water draining well lid is example, its base [1] internal diameter is 650mm, external diameter is 710mm, fixed cap [2] is cast as one with base [1], its camber line connects edge and connects edge apart from being 100mm to straight line, and linear edge is the profile of tooth square hole, after removable cover [3] embeds base [1], the profile of tooth square hole of its profile of tooth square hole and fixed cap [2] matches, and the circular inner hole of the φ 16 that the side has is also corresponding.Bearing pin [4] is penetrated in the circular inner hole of fixed cap [2] and removable cover [3] side, make it to be connected as one, and on the axis of removable cover [3], have " ten " font near camber line edge and carry and cover hole [5], just constituted the open-type well lid perpendicular to linear edge.During unlatching, stretch into to carry with hook and cover hole [5], upwards lift, removable cover [3] serves as that axle rotarily opens with bearing pin [4] just, and at ordinary times, removable cover [3] is connected as one by bearing pin [4] and fixed cap [2] and base [1], can prevent loss again.
