Abstract
The utility model provides a cover plate which is used for closing an opening of a box body. The cover plate comprises a primary cover plate covered on the opening of the box body and an auxiliary cover plate fixed above the primary cover plate movably. The primary cover plate comprises a previewing through hole, and the previewing through hole is covered by the auxiliary cover plate. Compared with the prior art, the cover plate is provided with the primary cover plate, the primary cover plate is provided with the previewing through hole, and the previewing through hole is covered by the auxiliary cover plate. When articles in the box body need to be detected, the cover plate does not need to be cut off, extra reworking caused by cut-off of the cover plate can be avoided, and disassembly capacity of the cover plate is improved.
Description
Technical field
The utility model relates to the speed reducer field, relates in particular to a kind of speed reducer cover plate.
Background technique
Along with the high speed development of modern industry, metal box is because its mechanical strength is large, occupancy load has by force widely application.

Therefore, be necessary to propose a kind of new cover plate to address the above problem.
The model utility content
The utility model provides a kind of cover plate of convenient disassembly.
For reaching above-mentioned model utility purpose, the utility model provides a kind of cover plate, be used for closed box opening, it comprises: the main cover plate and the movable auxiliary cover plate that is fixed in described main cover plate top that are covered in box opening, described main cover plate comprises the preliminary examination through hole, and described auxiliary cover plate covers described preliminary examination through hole.
As further improvement of the utility model, described preliminary examination through hole cross section is circular.
As further improvement of the utility model, the holding section that described main cover plate comprises main part and is arranged at described main part surface.
As further improvement of the utility model, described holding section is perpendicular to described main part.
As further improvement of the utility model, described holding section is circular.
As further improvement of the utility model, described auxiliary cover plate is arranged in the middle of the described holding section.
As further improvement of the utility model, described auxiliary cover plate is cylindrical body.
As further improvement of the utility model, described auxiliary cover plate outer surface supports the inner surface of described holding section.
As further improvement of the utility model, described preliminary examination through hole is arranged at the centre of described holding section.
Compared with prior art, cover plate provided by the utility model, by main cover plate is set, main cover plate is provided with the preliminary examination through hole, and cover described preliminary examination through hole by auxiliary cover plate, when needing to detect in the casing article, need not to cut off cover plate, avoid cutting off the extra heavy industry that cover plate causes, improved the ability to dismantle of cover plate.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing relevant of the present utility model in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
