Technical Field
The application relates to the technical field of prefabricated parts, in particular to a prefabricated access cover plate.
Background
The access cover plate is an opening and closing device which is loaded on a building or equipment and used for personnel to enter and exit, so that maintenance and overhaul of a machine or the use process of the building are facilitated, and the common structure is that the access cover plate is hinged to one side of the access cover plate after the access cover plate is opened on the building.
However, in some application fields of underground buildings or storage heavy equipment, the access opening is relatively large, and a relatively thick access cover plate is configured to ensure the reliability of the access cover plate, so that the access cover plate is very labor-consuming to open by manpower, if an electric control device or a hydraulic device is additionally arranged, the cost is greatly increased, and the maintenance of the electric control device or the hydraulic device is also a relatively complicated problem.
Disclosure of utility model
In order to solve the technical problems, the application provides the prefabricated access cover plate which can be opened simply by manpower, has simple and ingenious structural design and is low in economic cost.
In order to achieve the above purpose, the technical scheme of the utility model is as follows:
A prefabricated access panel comprising:
the outer frame is assembled in the overhaul port in a step buckling manner;
The prefabricated cover plate is provided with a fixed shaft in a penetrating manner along the width direction of the middle of the prefabricated cover plate, two ends of the fixed shaft in the length direction are provided with mounting blocks, and the outer frame is provided with a mounting groove for accommodating the mounting blocks;
The prefabricated apron length direction's both ends face is equipped with the stopper along self length direction slip, be equipped with the spacing groove that is used for holding the stopper on the frame.
Realize above-mentioned technical scheme, when this prefabricated access cover board of installation, outwards stretch out the stopper, keep flat prefabricated apron downwards, so that the installation piece inlay card can in the mounting groove, the stopper inlay card can in the spacing groove, the installation is very simple and convenient, when needs are opened, in contracting into prefabricated apron with the stopper from the spacing groove, upset prefabricated apron can make prefabricated apron rotate round the fixed axle this moment, because the fixed axle is located prefabricated apron middle part, operating personnel only need pay out very little power can open, have two openings after opening moreover, the manpower has greatly been saved, simple structure economic nature is high.
As one of the alternative embodiments of the present application, the limiting block is a T-shaped block.
As one optional implementation scheme of the application, the top of the limiting block is provided with a handle.
As one optional implementation scheme of the application, the limiting block is provided with a fastening bolt in a threaded penetrating way.
According to the technical scheme, after the limiting block moves to a certain position, the limiting block can be fixed by using the fastening bolt, so that the overturning operation of the prefabricated cover plate is more convenient.
As an alternative embodiment of the present application, both ends of the prefabricated cover plate in the length direction are provided with chamfers.
In summary, the present application includes at least one of the following beneficial technical effects:
1. Through with the rotation axis configuration in the middle part of prefabricated apron so that prefabricated apron can be more light by the upset, greatly reduced operating personnel's work load to utilize slidable stopper can conveniently realize unblock and the state of locking, guaranteed the stability of installation use, structural design is simple, economic cost is low.
Drawings
In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings that are required in the embodiments or the description of the prior art will be briefly described, it being obvious that the drawings in the following description are only some embodiments of the utility model, and that other drawings may be obtained according to these drawings without inventive effort for a person skilled in the art.
FIG. 1 is an overall block diagram of a prefabricated access panel;
Fig. 2 is an exploded structural view of a prefabricated access panel.
Reference numerals: 1. an outer frame; 2. prefabricating a cover plate; 3. a fixed shaft; 4. a mounting block; 41. a mounting groove; 5. a limiting block; 51. a limit groove; 6. a handle; 7. a fastening bolt; 8. chamfering.
Detailed Description
The application is described in further detail below with reference to fig. 1-2.
Referring to fig. 1, a prefabricated access panel according to an embodiment of the present application is disclosed, which includes an outer frame 1, and an edge of the outer frame 1 protrudes to facilitate a step snap-fit in an access opening; the novel multifunctional solar energy collecting device further comprises a prefabricated cover plate 2, wherein the prefabricated cover plate 2 is provided with a fixed shaft 3 in a penetrating manner along the width direction of the middle of the prefabricated cover plate 2, two ends of the fixed shaft 3 in the length direction are provided with mounting blocks 4, and the outer frame 1 is provided with a mounting groove 41 for accommodating the mounting blocks 4; the two end faces of the prefabricated cover plate 2 in the length direction slide along the length direction of the prefabricated cover plate, limiting blocks 5 are arranged on the two end faces of the prefabricated cover plate, and limiting grooves 51 for accommodating the limiting blocks 5 are formed in the outer frame 1. When this prefabricated access cover board of installation, outwards stretch out stopper 5, the prefabricated apron 2 of keeping flat downwards, so that installation piece 4 inlay card in mounting groove 41, stopper 5 inlay card can in spacing groove 51, the installation is very simple and convenient, when needs are opened, in the prefabricated apron 2 is followed spacing groove 51 shrink with stopper 5, upset prefabricated apron 2 can make prefabricated apron 2 rotate round fixed axle 3 this moment, because fixed axle 3 is located prefabricated apron 2 middle part, operating personnel only need pay out very little power can open, have two openings after opening moreover, the manpower has been greatly saved, simple structure economic nature is high.
