Abstract
The utility model discloses a movable protective cover plate. The movable protective cover plate comprises a frame-type cover plate which is defined by crimping three outer edges of the cover plate, wherein a movable gear is connected inside the frame of the cover plate, a movable plate is arranged inside the frame of the cover plate, a groove is arranged on the movable plate, and a spline which is engaged with the movable gear is arranged inside the groove. According to the technical scheme, the movable plate can be optionally retracted and extended according to the specific length of a hole, so that the movable protective cover plate can still meet construction requirements when the length of the hole changes. The movable protective cover plate is simple in structure and convenient to install and operate, not only effectively guarantees the safety of the hole during construction, but also avoids increase of the cost due to replacement of a new cover plate during construction, saves human and material resources, meets requirements for safety, attractive appearance and energy conservation, and has a standardized boosting effect on hole blocking.
Description
Technical field
The utility model belongs to technical field of building construction, particularly a kind of movable protective cover plate.
Background technology
According to the construction safety acceptance criteria of construction work, building exists in work progress, ventilating shaft hole, well hole, flue hole and other interim horizontal holes etc.In work progress, must seal temporarily, prevent falling and strike that falling object causes of people or thing, cause potential safety hazard, must carry out capping for this reason.After existing cover plate was made moulding, size can not change, and hole length usually changes owing to the difference of function, and original buying this moment cover plate can not be suitable for causes producing the waste of cover plate, and the problem that more renews the cost increase that cover plate brings.
Summary of the invention
The technical problem that the utility model will solve is: a kind of hole that can adapt to different size is provided, can avoids the waste of material, simple in structure, the movable protective cover plate of convenient installation and operation has overcome the deficiency of prior art.
The utility model is to constitute like this: it comprises that three outsides are curled into the cover plate 1 that surrounds shaped as frame; In the frame of cover plate 1, be connected with free gear 2; In the frame of cover plate 1, be provided with portable plate 3, on portable plate 3, have groove 4, in groove 4, be provided with tooth bar 5 with free gear 2 interlocks.
In the above-mentioned movable protective cover plate, place three sides of the portable plate 3 in cover plate 1 frame all to be curled into column, and cast iron cylinder 6 is set in post.
In the aforesaid movable protective cover plate, be respectively equipped with protruding 7 in cover plate 1 and portable plate 3 bottom surfaces.
Owing to adopted technique scheme, compare with prior art, portable plate can be according to any folding and unfolding of concrete length at hole, and when therefore length changed at the hole, the utility model still can satisfy the construction demand.Simple in structure, the convenient installation and operation of the utility model; Not only guaranteed the safety of hole in work progress effectively; Owing to more renew the cost increase that cover plate causes, saved the man power and material, and reached safe, attractive in appearance, energy-conservation demand in also having avoided constructing.The utility model standardization is strong, and the standardization booster action is played in the hole shutoff.
