Description
Technical field
The utility model is related to a kind of construction implement, the interim sealing hole dress in more particularly to a kind of job site
Put.
Background technology
It is wooden generally using one piece for the interim small-sized hole that job site is present in conventional building construction process
Thin plate is covered, and wooden thin plate easily blows loss off by wind, and plugging effect is generally undesirable.Even do not take and appoint in some job sites
What measure is blocked to hole, and to site operation inconvenience is brought.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of interim sealing hole device in job site, structure letter
Single, closure is difficult displacement, convenient disassembly.
The utility model solves the technical scheme that its technical problem adopted and is to provide a kind of interim hole envelope in job site
Block apparatus, including upper film, lower film and connecting tube, the upper film and lower film assemble to be formed using cloth film and steel skeleton, the reinforcing bar
Frame is in integrally coniform rim structure of umbrella, and the lower end of connecting rod, the opening direction of lower film are mounted at the top of the lower film
Upward, the connecting tube is internally provided with unidirectional spacing toothing, and top and the slip limited block of the upper film are fixed, upper film
Down, the slip limited block matches and can be along connecting tube slide downward opening direction with unidirectional spacing toothing.
A kind of preferred embodiment as the utility model, the steel skeleton top of the lower film is provided with circular ring structure, under
Film passes through interference fit between circular ring structure and connecting tube and installs fixation.
Used as the utility model another preferred embodiment, the steel skeleton of the upper film and lower film is provided with 3～5
Diagonal brace skeleton.
Used as the further improvement to above-mentioned embodiment, the diagonal brace skeleton is uniformly distributed along the circumference of steel skeleton.
Used as the utility model another preferred embodiment, the connection tube wall is provided with out along whole length direction
Mouthful, the top of the upper film is fixed by opening with the slip limited block inside connecting tube.
As the utility model another preferred embodiment, the rectangular triangle in section of the unidirectional limiting tooth
Structure.
Used as the utility model another preferred embodiment, the connecting tube adopts steel pipe.
Beneficial effect
In the utility model, lower film is arranged on the lower end of connecting tube, and lower film is positioned over the lower end at hole when using, and leads to
Cross film and slide down to appropriate position, so as to block to the upper end at hole, spacing between upper film and connecting tube is matched somebody with somebody
Close cause upper film will not upward sliding come off, so as to ensure that the plugging device is difficult displacement when hole is blocked, with long timeliness
The characteristics of；Upper film, lower film can be disassembled from connecting tube, conveniently re-assemblied and used, and simple structure is practical.
Description of the drawings
Fig. 1 is overlooking the structure diagram of the present utility model.
Fig. 2 is positive structure schematic of the present utility model.
Fig. 3 is the utility model connecting tube internal structure schematic diagram.
Specific embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than restriction scope of the present utility model.In addition, it is to be understood that in the content for having read the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
The interim sealing hole device in a kind of job site as depicted in figs. 1 and 2, including upper film 1, lower film 2 and connecting tube
3.Upper film 1 and lower film 2 are formed using cloth film 4 and the assembling of steel skeleton 5, and it is in coniform rim structure of umbrella that steel skeleton 5 is overall, is provided with 3
～5 diagonal brace skeletons are used to open cloth film 4, and diagonal brace skeleton is uniformly distributed along the circumference of steel skeleton 5.Connecting tube 3 adopts steel pipe
Make.
The top of the steel skeleton 5 of lower film 2 is provided with circular ring structure, and lower film 2 is mounted on connecting rod 3 by the circular ring structure
Lower end, be attached by way of interference fit between the two.Upward, lower film 2 is located at the opening direction of lower film 2 when using
The lower end at hole, blocks to the lower end at hole.
The tube wall of connecting tube 3 is provided with opening along whole length direction, and connecting tube 3 is internally provided with unidirectional spacing toothing,
The structure of the rectangular triangle in section of unidirectional limiting tooth.The opening that the top of upper film 1 is opened up by the side wall of connecting tube 3 be connected
Slip limited block 6 inside pipe 3 is fixed, the opening direction of upper film 1 down, the unidirectional limit inside slip limited block 6 and connecting tube 3
The structure of position tooth matches, and the slide downward of slip limited block 6 is enabled to by the upper film 1 of pressing, so as to drive upper film 1 to downslide
It is dynamic, stop pressing when reaching correct position such that it is able to which the upper end at hole is blocked.In addition, slip limited block 6 is subject to single
Will not move up to the position-limiting action of limiting tooth, therefore, the plugging device is difficult displacement when hole is blocked, and practicality is significantly
Strengthen.
