Description

Technical field:

[0001] The present invention belongs to the field of smart home technology, and in particular relates to a foldable window reinforcement mechanical device and a use method thereof. Background technology:

[0002] Investigations and studies have shown that typhoons develop from tropical cyclones. When typhoons blow through buildings, they will cause nonlinear random forced vibration problems, namely wind vibration response. When doors and windows are blown open or damaged by strong winds, openings are formed in the building, and wind suddenly rushes in from the openings. The pulsating internal pressure of the building increases sharply, making the roof structure more susceptible to wind damage due to the combined action of internal and external pressures. Post-disaster investigations show that the combined action of internal and external pressures after the sudden opening of the window damage is a major cause of roof damage. Most of the door and window glass materials on the market cannot withstand the load brought by strong typhoons. Due to the insufficient strength of doors and windows, it is difficult to resist typhoons, resulting in huge losses to houses, and the glass fragments produced by the broken windows pose a threat to the safety of pedestrians. Therefore, when strong winds come, it is very necessary to reinforce the windows, especially in coastal strong typhoon areas. In order to resist typhoons, the most commonly used method is to use tape to stick the glass of the entire window together, but the reinforcement effect is limited. Not only is the amount of tape used in sticking a large amount, but it is also very time-consuming to clean up the tape after the typhoon. Summary of the invention:

The integral support module includes two supports 4 of the same shape and size, a fixing ring 10, a fixing rod 11, a bolt 12, a pin 13 and a shoe 3. The support 4 can be made of a high-strength light alloy, such as an aluminum alloy, etc. A circular through hole is opened in the middle region of the support 4 to facilitate connection with other parts. In order to reduce weight and meet the needs of slider movement, two through grooves are opened on both sides of the circular hole, and circular through holes are arranged at both ends of the support 4. One end of the fixing rod 11 has a step, and the other end passes through the second circular through hole 4a in the middle region of the two supports 4 in turn, wherein the second circular through hole 4a in the middle of the support 4 is gap-matched with the fixing rod 11, and finally connected to the fixing ring 10 by welding. For ease of installation, the fixing ring 10 is composed of two semicircular rings and connected by bolts 12, so that when the screw 1 rotates, the center position of the two supports 4 is always fixed, and the two screw nuts 2 move, thereby ensuring the symmetry of the entire device during use.

The middle part of the screw rod 1 is an annular limit groove 1a, and the two sides of the annular limit groove 1a are distributed with threads with opposite rotation directions. The right end face of the screw rod 1 is provided with a regular hexahedron 1b. By putting a hexagonal wrench on the regular hexahedron 1b and rotating the screw rod 1, two symmetrically distributed screw nuts 2 move towards or away from each other at the same time, driving the pull rod 6 and the connecting rod 5 to move, thereby dragging the first slider 7 and the second slider 8 to move, driving the suction cup 9a and the support 9c to move, the two sections of the connecting short rod 16 have opposite rotation directions and a flat position is milled in the middle position, and the length of the thread matching between the connecting short rod 16 and the first slider 7 and the second slider 8 can be adjusted to adjust the position of the suction cup 9a and the support 9c. The two ends of the screw rod 1 are smooth rods, which is conducive to quickly opening and quickly folding the bracket. There are two connecting rods 5, which are symmetrically distributed on both sides of the screw rod 1. There are four pull rods 6, which are symmetrically distributed.

[0037] The screw nut 2 is connected to the screw 1 by threads, and a threaded through hole 2a is provided on the screw nut 2. The first connecting pin 2b is connected to the screw nut 2 by welding. The first connecting pin 2b passes through the ninth circular through hole 6a of the two tie rods 6 in turn, and the first connecting pin 2b is clearance-matched with the ninth circular through hole 6a of the tie rod 6. A groove 5a is provided in the middle area of ​​the connecting rod 5, and a plurality of through holes with the same structure, the fifth circular through hole 5b and the sixth circular through hole 5c, are symmetrically arranged on both sides of the groove 5a. One of the holes can be selected according to different window sizes and the opening degree of the two brackets 4 in the reinforcement device. The ninth circular through hole 6a and the tenth circular through hole 6b are provided at both ends of the tie rod 6, and the second connecting pin 14 passes through the tenth circular through hole 6b of the tie rod 6 and the sixth circular through hole 5c of the connecting rod 5 in turn; the second connecting pin 14 is clearance-matched with the tenth circular through hole 6b of the tie rod 6, and the second connecting pin 14 is interference-fitted with the sixth circular through hole 5c of the connecting rod 5.

[0038] The first slider 7 and the second slider 8 are both detachable block structures. The front and rear surfaces are two rectangular thin plates 7a with the same structure and a relatively wide width. The middle part is thicker but narrower. They are connected by bolts, and grooves are formed on both sides, which are convenient for installation on the bracket 4 and can slide on the bracket 4. The third connecting pin 15 has an interference fit with the eleventh circular through hole 7b on the first slider 7, and a clearance fit with the seventh circular through hole 5e of the connecting rod 5. The twelfth circular through hole 8a on the second slider 8 is matched with the sleeve shaft 9d, and the second nut 2y and the third nut 3y are threadedly matched with the sleeve shaft 9d to fix the sleeve shaft 9d on the second slider 8. The first slider 7 and the second slider 8 are connected together by threads at both ends of the connecting short rod 16. Since the length of the threads at both ends of the connecting short rod 16 and the first slider 7 and the second slider 8 is adjustable, the position of the suction cup 9a supporting the window glass can be adjusted.

[0039] The glass fixing module includes a suction cup 9a, a support 9c, a threaded rod 9b, a sleeve shaft 9d, a first nut 1y, a second nut 2y, a third nut 3y and a fourth nut 4y; the core of the sleeve shaft 9d is hollow and has threads distributed on the periphery, and the sleeve shaft 9d and the support 9c can be fixed by the cooperation of the step at the lower end of the sleeve shaft 9d and the first nut 1y; the second nut 2y is screwed so that one end face thereof rests on the fixed bracket 4, so that the suction cup 9a which is tightly attached to the glass on the window is pressed by the support 9c on all sides, and the glass of the window is also supported by the support 9c, and the third nut 3y is screwed to fix the sleeve shaft 9d on the bracket 4. The suction cup 9a is made of soft material, and the threaded rod 9b is connected to the suction cup 9a as a whole. The fourth nut 4y is turned to make the threaded rod 9b rise, driving the middle area of ​​the suction cup 9a to leave the adsorbed window glass, thereby forming a negative pressure and generating an adsorption force, which generates both a supporting force and an adsorption force on the glass, thereby improving the rigidity and strength against typhoons, and effectively resisting the damage of typhoons. After the typhoon, when the reinforcement device is not in use, first restore the suction cup 9a to its original state and the support 9c to leave the window glass, then reversely rotate the screw rod 1, loosen the reinforcement device, and fold the reinforcement device up.
