Description
Technical Field
The utility model relates to a sunshade screen piece hangs a mouthful additional strengthening relates to one kind and is rolling up the curtain mat when carrying out the rolling, carries out the structure of strengthening to the transmission connecting portion between the curtain piece, belongs to the environmental protection building field. In particular to a structure for reinforcing the position of a hanging opening and improving the transmission connection strength by adding a reinforcing plate at the bending position of the hanging opening.
Background
At present, an external sunshade rolling curtain mat is formed by connecting a plurality of curtain sheets, the shapes of the curtain sheets are various, the simplest one is that a single-layer alloy sheet is adopted, the upper edge and the lower edge of the sheet are rolled, two adjacent sheets are connected through a connecting shaft, the two sheets rotate through the connecting shaft, the structure is simple, the sheet is easy to block when being folded and unfolded, the strength of the metal sheet is low, the bending position can be deformed when being forcibly pulled, so that the two curtain sheets are scattered, and the shading effect is influenced, the existing double-layer curtain sheet adopts a hollow structure, is connected and matched through a hanging opening and a hook, but the hanging opening position can only be simply bent and hung, the single bending can not improve the strength of the hanging opening, the lap joint is not arranged between two bent side surfaces, so that the hanging part of the hanging opening is suspended, and the bending deformation is easy to occur when being pulled by the hook, the power transmission between the curtain pieces is not direct, the strength of the curtain pieces is influenced, simultaneously, along with the increase of the connection quantity of the curtain pieces, the load borne by the hanging opening of a single curtain piece is changed, the deformation is easy to occur, the shading effect and the transmission performance of the connection position of the curtain pieces are influenced, the rib plates and the hanging openings are adopted to form a rectangle in the existing reinforcing modes, the reinforcing outline is quadrilateral, and the structure is unstable.
Disclosure of Invention
In order to improve the condition, the utility model relates to a sunshade screen piece hangs a mouthful additional strengthening provides one kind through adding the reinforcing plate in hanging a mouthful crooked position, strengthens hanging a mouthful position, improves transmission joint strength's structure. The bearing strength of the curtain sheet hanging opening can be improved.
The utility model relates to a sunshade screen piece hangs a mouthful additional strengthening realizes like this: the utility model relates to a sunshade screen piece hangs a mouthful additional strengthening comprises curtain piece main part, string mouth and reinforcing plate, and the couple has been put to curtain piece main part top edge, equidistant opening has a plurality of bar holes on the couple, and the mouth has been put to curtain piece lower limb, and a plurality of reinforcing plate equidistance are arranged in and are hung a mouthful crooked position, the reinforcing plate middle part position is bent, and bends line perpendicular to and hang a mouthful crooked line, the reinforcing plate direction of bending and hang a mouthful crooked opposite direction, the bar hole staggered distribution on reinforcing plate and the couple, form tetrahedral cavity between reinforcing plate and the string mouth.
When the hanging mouth is used, the hook on one curtain sheet is matched with the hanging mouth on the other curtain sheet, when the hanging mouth is stressed, the hanging mouth position maintains the hanging mouth through the reinforcing plate, so that the stress force arm of the hanging mouth is shortened, the strength of the hanging mouth is increased, because an included angle theta exists between the hanging mouth and the gravity direction, the bearing gravity G on the upper end surface of the hanging mouth is decomposed into F2 along the hanging mouth direction and F1= Gsin theta vertical to the hanging mouth direction, when the reinforcing plate is not arranged, the length of the hanging mouth is fixed to be L, the torsion force received at the bending position is L F1= LGsin theta, when the hanging mouth is strained, the included angle theta between the hanging mouth and the gravity is gradually increased, so that the F1 is gradually increased and is finally equal to G, when the hanging mouth position is provided with the reinforcing plate, the reinforcing plate is discontinuously distributed at the hanging mouth position, so that the continuity of the hanging mouth length is interrupted, the length of the discontinuous position is less than the force arm, the force acting on the integral hanging opening is less than LGsin theta, meanwhile, the reinforcing plate decomposes the pulling force F3 of the hanging opening to form component force in the direction of the hanging opening and component force perpendicular to the direction of the hanging opening, the decomposed force arm is equal to the distance between the corresponding position of the reinforcing plate and the bending line of the hanging opening, the downward pressure formed by the gravity G is offset, the bearing capacity of the hanging opening is increased, meanwhile, a tetrahedral cavity is formed between the reinforcing plate and the hanging opening to absorb vibration, the hanging opening is communicated with the curtain sheet main body, filler is injected, a heat insulation layer is formed, and the purpose of reinforcing the transmission connecting part between the curtain sheets when the rolling curtain mat is rolled is achieved.
Has the beneficial effects.
The structure is simple, and the device is convenient and practical.
And secondly, the bearing strength of the curtain sheet hanging opening can be improved.
Thirdly, the shading influence caused by the looseness of the connection position of the curtain piece can be avoided.
