Description

Duplex windproof hook

The invention relates to a component of a rolling door; in particular, it refers to the disclosure of an innovative structure of a double-piece windproof hook.

The rolling door that can be lifted up and down is composed of several rolling door pieces that are connected up and down in sequence. Each of the rolling door pieces is provided with a head at both ends. They are arranged vertically on both sides of the door where the rolling door is to be installed, facing each other sideways. The guide rail forms a long guide groove, and the guide rail forms two baffles at the opening of the guide groove. The windproof hook enters the guide groove When the rolling door is subjected to an external force directed to the front side of the rolling door, such as wind blowing or impact of foreign objects, the baffle plate forms a stop for the windproof hook to leave the guide groove, so that the windproof hook is not easy to detach from the guide rail, and the two sides of the rolling door The side retaining pivot fits into the rail.

The known windproof hook is punched and formed by a sheet metal sheet, and the central part of the windproof hook protrudes forward to a front side, which is used to lean against the head, and uses a bolt to combine the front side and the The two wings are respectively connected to the two sides of the front side, and each of the wings extends to the two sides of the front side respectively. When the windproof hook is arranged on the guide rail, each of the wings enters the guide groove respectively, and the front side The part protrudes outside the guide groove through each of the baffles, and the baffle forms a stop for the wing.

After investigation, the following problems and disadvantages still exist in the windproof hook in the actual application experience: when the rolling door bears the external force directed to the front side of the rolling door, the rolling door sheet forms the first function of pulling the windproof hook away from the guide groove force, the wing abuts against the baffle, and the baffle forms a second force on the wing pointing toward the inside of the guide groove, the first force and the second force form a positive correlation, and the external force When the effect is too large, the second acting force will easily deform the wing, and the wing will rotate relative to the front side. The wings on both sides of the front side are relatively close to each other. The width between the two sides of the wing is reduced, and when each wing passes through the baffle and exits the guide groove, the two sides of the rolling door are separated from the restriction of the guide rail, and the strength of the windproof hook against external force needs to be improved .

Please refer to Fig. 1 to shown in Fig. 7, it is the embodiment of the multi-piece windproof hook of the present invention, but these embodiments are only for illustration, and are not limited by this structure on the patent application.

As shown in Figures 1 to 6, the first embodiment of the double-piece windproof hook includes a main body 10, a support plate 20 and two joint parts 30, wherein the main body 10 is stamped and formed from a metal plate, and the main body 10 forms a front plate part 11, the front plate part 11 is used to lean against the head 92 of the rolling door, the two sides of the front plate part 11 respectively form a connecting part 12 backward, and the two wing parts 13 respectively connect the rear side of each connecting part 12, And each of the wing portions 13 extends toward both sides of the main body 10 respectively, and each of the wing portions 13 respectively forms a side wall 14 on the outer side away from the connecting portion 12, and each of the side walls 14 has an inclined surface 15 respectively. 15 is located on the side of the side wall 14 facing the rear side of the front panel 11 , and a limiting edge 16 is formed at the adjoining position of the inclined surface 15 and the wing portion 13 .

The support plate 20 is formed by a metal plate, the support plate 20 is located between the side walls 14, and the support plate 20 is against the limiting edge 16, the limiting edge 16 forms a limit to the supporting plate 20, the support When the board 20 is arranged between the side walls 14 from the rear side of the main body 10 forward, the formation of each of the inclined surfaces 15 can improve the positioning of the supporting board 20 moving from the rear to the front and abutting against the limiting edge 16 Convenient operation, the two sides of the support plate 20 respectively form a side 22, each of the side 22 is laterally opposite to each of the slopes 15, so that two slots 40 are respectively formed between each of the side 22 and each of the slopes 15 Since the support plate 20 abuts against each of the limiting edges 16 , the inclined surface 15 cooperates with the laterally adjacent side surface 22 to close the front side of the slot 40 .

Each of the joints 30 is respectively arranged on both sides of the support plate 20, and the two sides of the joint 30 are respectively connected to the slope 15 and the side 22, and the main body 10 and the support plate 20 are fixedly connected by each of the joints 30, In a direction passing through each of the side walls 14 , the support plate 20 supports each of the side walls 14 .

After the support plate 20 is arranged between the side walls 14, the rear side of each wing portion 13 is respectively opposite to the front side of the support plate 20, and solder is filled in the gap 40 by means of brazing to form the joint. 30 is a preferred implementation option, and the present invention can also choose to use adhesive means to fill the adhesive into the gap 40 to form the joint 30; since the inclined surface 15 cooperates with the laterally adjacent side 22, the gap The front side of the channel 40 is closed, and when the joint 30 is formed, the solder or the adhesive is filled into the channel 40 to form the joint 30, and the solder or the adhesive will not enter the wing 13 There is no direct or indirect connection between the wing portion 13 and the support plate 20 due to the solder or the adhesive.

With the above-mentioned structural composition and technical features, Embodiment 1 mainly utilizes the joint member 30 combined with the main body 10 and the support plate 20 formed by the metal plate to form a structure in the form of multiple sheets, which are respectively located on the sides of the main body 10. The side wall 14 and each of the wing portions 13 are connected to each other through the support plate 20 and each of the joint members 30 to support each other against external forces.

When the external force directed to the front side of the rolling door 96, such as wind blowing or foreign matter impact, acts on the rolling door 96, the rolling door 96 forms a pulling force on the front plate portion 11 through the sealing head 92, and each of the baffles 84 respectively The front side of each wing 13 forms a stopper, and the supporting plate 20 forms a supporting effect on each side wall 14 pointing to the side wall 14 through each connecting piece 30, and each side wall 14 is difficult to face the direction of the supporting plate 20 deformation, Embodiment 1 is not easy to deform and break away from the guide rail 80 , and the two sides of the rolling door can be kept pivoted into the guide rail 80 .

The pulling force, the limiting effect of the baffle plate 84 and the supporting effect of the support plate 20 on the side wall 14 make the wing 13 on the side facing away from the direction of the external force be rotated around the limiting edge 16 and subjected to Tensile deformation, because the support plate 20 abuts against each of the limiting edges 16, the solder or the adhesive will not enter the rear side of the wing 13 and the support plate 20 Between, the wing 13 and the support plate 20 will not form a direct or indirect connection due to the solder or the adhesive, and the support plate 20 will not be deformed with the deformation of the wing 13, so that the Between the wing 13 and the support plate 20, a gap 17 is formed along with the deformation of the wing 13, and the gap 17 expands as the degree of deformation of the wing 13 increases. When the pulling force is small, the wing 13 forms elastic deformation, and when the pulling force is weakened or eliminated, the wings 13 return to the original state. When the pulling force is too large, although it may cause permanent deformation of the wings 13 and it is difficult to return to the original state, the main body 10 will not break away from the guide rail 80 , the side wall 14 and the support plate 20 are still left in the guide groove 82, and the rolling door can still play the role of blocking the door to prevent unscrupulous people from taking the opportunity to invade.

On the other hand, the point where the external force acts on the rolling door sheet 96 is usually located in the central area of the width of the rolling door sheet 96 facing the outside of the door, so that the wing 13 facing the inside of the door is supported by the baffle 84 The extrusion effect, the extrusion action acts on the side of the adjacent side of the support plate 20 through the wing 13, the side wall 14 adjacent to the wing 13 and the joint 30 connecting the side wall 14 22, the width direction of the support plate 20 is located in the direction of resisting the extrusion, the support plate 20 has a good resistance to the extrusion and is not easy to deform, facing the wing 13 outside the door, the side The wall 14 and the joint 30 support the support plate 20 against the above-mentioned extrusion, transmit and disperse the influence of the external force, and improve the lack of mutual connection between the two wings of the conventional windproof hook, which cannot form mutual support. Facing the problem of external force.

Furthermore, two through holes 50 are respectively formed between the front plate portion 11 and the support plate 20, accordingly, when the rolling door is installed, a cable (not shown) can be selected to pass through each of the through holes 50 , so that the draglines are serially arranged in series with several Embodiment 1.

As shown in FIG. 7 , Embodiment 2 is mainly different from Embodiment 1 in that the rear side of each of the wing portions 13 contacts the front side of the support plate 20. However, each of the wing portions 13 of Embodiment 2 is the same as that of Embodiment 2. - The support board 20 is not connected.
