DETAILED DESCRIPTION OF THE EMBODIMENTS
[0034] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0035] Referring to Figures 1-7 , an embodiment provided by the present utility model: a laminated glass, including a glass body 1, U-shaped vertical plates 2 are arranged on both sides of the glass body 1, U-shaped horizontal plates 3 are abutted against the upper and lower ends of the glass body 1, air bags 4 are fixedly connected to the closed ends inside the two U-shaped vertical plates 2, push plates 5 are abutted against one end close to each other of the two air bags 4, and the ends close to each other of the push plates 5 are respectively abutted against both ends of the glass body 1. Grooves 6 are opened at the front and rear ends inside the two U-shaped vertical plates 2, U-shaped clamping plates 7 are slidably connected inside the multiple grooves 6, and the multiple grooves 6 are communicated with the air bags 4 through air guide holes 8. Limit grooves 9 are opened at the upper and lower ends of the two U-shaped vertical plates 2, trapezoidal blocks 10 are slidably connected inside the multiple limit grooves 9, grooves 11 are opened inside the multiple trapezoidal blocks 10, trapezoidal blocks 12 are slidably connected inside the multiple grooves 11, springs 13 are fixedly connected to one end of the multiple trapezoidal blocks 12 away from the grooves 11, fixing plates 14 are fixedly connected to one end of the multiple springs 13 away from the trapezoidal blocks 12, and the outer sides of the fixing plates 14 are respectively fixedly connected to both sides inside the upper and lower U-shaped horizontal plates 3; the upper and lower ends of the push plates 5 are respectively slidably connected to the upper and lower ends inside the two U-shaped vertical plates 2, and the upper and lower ends of the multiple U-shaped clamping plates 7 are respectively slidably connected to the upper and lower ends inside the U-shaped vertical plates 2; multiple sleeves 18 are fixedly connected to the closed ends inside the multiple grooves 6, sliding rods 19 are slidably connected inside the multiple sleeves 18, and one end of the multiple sliding rods 19 away from the sleeves 18 is fixedly connected to the ends away from each other of the front and rear U-shaped clamping plates 7; skateboards 20 are fixedly connected to the ends close to each other of the upper and lower trapezoidal blocks 10, and the outer sides of the multiple skateboards 20 are slidably connected inside the limit grooves 9.
[0036] Specifically, the push plate 5 can apply pressure to the airbag 4 after contacting the glass body 1, so that the gas inside the airbag 4 can enter the groove 6 through the evenly distributed air guide holes 8, and as the air pressure inside the groove 6 increases, the U-shaped clamping plate 7 can be pushed by the air pressure to approach and contact the glass body 1 from the front and back sides of the glass body 1, so as to achieve the purpose of clamping glass bodies 1 of different thicknesses. In addition, the gas inside the airbag 4 can also enter the limiting groove 9 through the hole connecting the airbag 4 and the limiting groove 9. Similarly, as the air pressure inside the limiting groove 9 increases, the trapezoidal block 10 can move a certain distance away from the airbag 4, and when the worker moves the trapezoidal block 1 When the U-shaped cross plate 3 is close to the glass body 1 and the U-shaped vertical plate 2, the trapezoidal block 2 12 inside the U-shaped cross plate 3 can gradually contact the trapezoidal block 10 through the inclined surface, and then as the U-shaped cross plate 3 continues to move, the trapezoidal block 2 12 can overcome the resistance applied by the spring 13 and slide along the inclined surface in contact with the trapezoidal block 10. When the U-shaped cross plate 3 is tightly fitted with the glass body 1, the trapezoidal block 2 12 can move to a position facing the groove 2 11, and then under the action of the spring 13, the trapezoidal block 2 12 can move to a position facing the groove 2 11. The second trapezoidal block 12 can be made to enter the second groove 11 by using the second trapezoidal block 10. At this time, the contact between the first trapezoidal block 10 and the second trapezoidal block 12 changes from the inclined surface contact to the vertical surface contact. Therefore, the first trapezoidal block 10 and the second trapezoidal block 12 can be locked with each other to prevent the U-shaped vertical plate 2 and the U-shaped horizontal plate 3 from moving on their own. In summary, the purpose of using the U-shaped clamping plate 7 inside the U-shaped vertical plate 2 and the U-shaped horizontal plate 3 to block the four sides of the glass body 1 can be achieved, and the PVB layer inside the glass body 1 of different thicknesses can be prevented from being corroded by water during subsequent use or storage, resulting in a decrease in the bonding strength. The fixing of the U-shaped vertical plate 2 and the U-shaped horizontal plate 3 is simple and convenient, and the U-shaped plate 7 can be used for subsequent installation. The vertical plate 2 and the U-shaped horizontal plate 3 provide a more solid and reliable installation surface. In addition, the U-shaped vertical plate 2 can ensure that the push plate 5, the U-shaped clamping plate 7 and the glass body 1 will not deflect during movement. At the same time, since the U-shaped clamping plate 7 is in contact with the U-shaped vertical plate 2, the relevant sealing ring can prevent the gas leakage inside the groove 6. The evenly distributed sleeves 18 and sliding rods 19 can further limit the movement range and direction of the U-shaped clamping plate 7, and disperse the force on the contact part between the U-shaped clamping plate 7 and the U-shaped vertical plate 2. In addition, the slide plate 20 can prevent the trapezoidal block 10 from excessive displacement and disengagement from the limit groove 9 while guiding the movement of the trapezoidal block 10.
[0037] Reference Figure 6 and Figure 7, a plurality of trapezoidal blocks two 12 are provided with grooves three 15 on one side close to the trapezoidal block one 10, capsules 16 are fixedly connected inside the plurality of grooves three 15, and a plurality of ejector pins 17 are fixedly connected to the closed ends inside the plurality of grooves two 11; the plurality of ejector pins 17 are all facing the capsules 16, and the front and rear ends of the trapezoidal block two 12 are respectively slidably connected to both sides of the front and rear ends inside the U-shaped cross plate 3.
[0038] Specifically, the groove three 15 can accommodate the capsule 16 storing glue inside, and then after the trapezoidal block two 12 enters the groove two 11 inside the trapezoidal block one 10, the uniformly distributed ejector pins 17 inside the groove two 11 can pierce the capsule 16. At this time, the glue inside the capsule 16 can flow out and the moving parts such as the trapezoidal block one 10, the trapezoidal block two 12, and the U-shaped vertical plate 2 can be fixedly bonded by a large area inside the U-shaped cross plate 3, achieving the purpose of further strengthening the fixation and effectively sealing the gaps between the moving parts from the inside by the glue inside the capsule 16. In addition, the U-shaped cross plate 3 can limit the movement direction of the trapezoidal block two 12, thereby preventing the trapezoidal block two 12 from deflecting and affecting the mutual locking between it and the trapezoidal block one 10. Further, since the ejector pins 17 are facing the capsules 16, the normal use of the capsules 16 and the ejector pins 17 can be avoided.
[0039] Working principle: Place the heated glass body 1 on the surface of the relevant processing table, and then press the U-shaped vertical plate 2 from both sides towards the glass body 1. As the glass body 1 comes into contact with the push plate 5 inside the U-shaped vertical plate 2, the push plate 5 can be forced to squeeze the airbag 4. At this time, the gas inside the airbag 4 can continuously enter the first groove 6 through the evenly distributed air guide holes 8. Further, as the gas inside the first groove 6 and the airbag 4 is compressed, its air pressure intensity gradually rises, and the U-shaped clamping plate 7 located inside the first groove 6 can approach the glass body 1 under the action of air pressure, so as to achieve the purpose of clamping glass bodies 1 with different thicknesses from both sides at the front and rear ends of the glass body 1, preventing water vapor from contacting the PVB layer inside the glass body 1 during subsequent storage or use. And at this time, the position of 1 inside 2 can be limited, so the situation of 1 shifting can be avoided. At the same time, as the airbag 4 is compressed and deformed, part of the gas inside it can also enter the limiting groove 9 through the holes communicating with the limiting groove 9. Similarly, the first trapezoidal block 10 and the sliding plate 20 inside the limiting groove 9 can move away from the airbag 4 under the action of air pressure. And because the moving distance of the first trapezoidal block 10 is greater than the moving distance that the U-shaped clamping plate 7 can move, and within the common thickness range of laminated glass, by observing the movement of the first trapezoidal block 10 and its stop due to reaching the limit position, the staff can judge whether the U-shaped clamping plate 7 has clamped the glass body 1. Further, the U-shaped horizontal plate 3 can be brought closer to the glass body 1 and the U-shaped vertical plate 2. The second trapezoidal block 12 inside the U-shaped horizontal plate 3 can contact the first trapezoidal block 10 through an inclined surface during the movement of the U-shaped horizontal plate 3. At this time, because the first trapezoidal block 10 cannot move under the action of air pressure, the second trapezoidal block 12 can slide along the surface of the first trapezoidal block 10 by overcoming the thrust applied by the spring 13. When the U-shaped horizontal plate 3 is completely attached to the glass body 1 and the U-shaped vertical plate 2, the second trapezoidal block 12 can move to the position directly opposite the second groove 11. Then, under the action of the spring 13, the second trapezoidal block 12 can enter the second groove 11. At this time, the first trapezoidal block 10 and the second trapezoidal block 12 no longer contact through the inclined surface, so the first trapezoidal block 10 and the second trapezoidal block 12 can be locked to each other, and both sides of the first trapezoidal block 10 are attached to the inner side surface of the U-shaped horizontal plate 3. Therefore, the U-shaped vertical plate 2 and the U-shaped horizontal plate 3 can be prevented from separating by themselves, and then the probability of the PVB layer inside the glass body 1 contacting water during subsequent use or storage can be reduced by the close contact between the U-shaped vertical plate 2, the U-shaped horizontal plate 3, the U-shaped clamping plate 7, etc. and the glass body 1. In addition, a rubber layer can be added to the contact area between the U-shaped horizontal plate 3, the U-shaped clamping plate 7 and the glass body 1 according to requirements to increase the sealing effect through the local deformation of the rubber layer. After the second trapezoidal block 12 enters the second groove 11, the capsule 16 inside the third groove 15 can contact the evenly distributed thimbles 17, and then the thimbles 17 can be used to rupture the capsule 16 to release the glue inside the capsule 16. Then, the fluidity of the glue can be used to make it flow along the gaps between the moving parts such as the second trapezoidal block 12, the first trapezoidal block 10, the U-shaped vertical plate 2, the U-shaped horizontal plate 3, etc., so as to effectively seal the gaps from the inside over a large area.To prevent the sealing effect from being unsatisfactory when only the outer side is sealed with glue due to the small contact area and easy to be scratched by foreign objects, the fixing effect between the first trapezoidal block 10, the second trapezoidal block 12, etc. is further improved, and the probability of moisture contacting the PVB layer inside the glass body 1 through the gap is reduced.
