[0002] Double-layer laminated glass consists of two glass substrates and a film sandwiched between the two glass substrates, and the three are then sent into an autoclave for sintering processing.

[0003] Chinese utility model patent application number CN202322024554.2 discloses a plug for point-supported laminated glass furnace, which is made of silicone and includes a plug post and a plug cap fixed to the top of the plug post. The height of the plug post is less than the thickness of the laminated glass, a convex ring is provided in the middle of the plug post, and a chamfer is provided at the bottom of the plug post. Its function is to be inserted into the glass hole in front of the laminated glass furnace to prevent the softened film from flowing into and bonding to the glass hole.

[0004] However, in actual applications, it is found that the above-mentioned prior art has the following problems that need to be solved urgently: first, the thickness of a single piece of laminated glass commonly available on the market ranges from 3mm to 30mm, so the thickness of double-layer laminated glass is 6mm to 60mm plus the thickness of the film. When the glass hole is deep, the above-mentioned plugging plug is difficult to insert and remove, which affects the processing efficiency; second, the convex ring is pressed and fixed to the inner wall of the mounting hole of the laminated glass by fitting, squeezing and fixing, so that the plug column does not fit and block the laminated gap in the glass hole, and a small amount of glue will flow into the glass hole and solidify.

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like Figure 1 As shown, in the present embodiment, a hole plugging plug for a double-layer laminated glass furnace comprises a cylindrical plug column 1 and a cylindrical seat tube 2, a plug cap 11 is fixed on the top of the plug column 1, a threaded rod 3 is rotatably arranged in the plug column 1 along its length direction, a yield groove 111 is provided on the upper end surface of the plug cap 11, an adjusting end head 31 is rotatably arranged in the yield groove 111 at the upper end of the threaded rod 3, a screw groove 32 cooperating with a screwdriver is provided on the adjusting end head 31, a screw sleeve 4 is threadedly connected to the threaded rod 3, a plurality of side arms 41 are circumferentially extended on the screw sleeve 4, an annular plugging strip 5 is fixedly embedded on the side arm 41, a plurality of sliding holes 12 corresponding to the side arms 41 are circumferentially opened at the lower end of the plug column 1, the side arms 41 are slidably arranged in the sliding holes 12, an adjusting sleeve 6 rotatable along its circumferential direction is provided on the upper port edge of the seat tube 2, the plug column 1 is penetrated in the seat tube 2 and is threadedly connected with the adjusting sleeve 6.

[0018] The seat tube 2 is buckled on the glass mounting hole, and the lower end of the plug column 1 is aligned with the glass mounting hole and inserted. The plug column 1 is extended into the glass mounting hole by rotating the adjusting sleeve 6 until it cannot rotate. At this time, the blocking strip 5 is pressed against the gap between the two glass substrates to hold the film. Compared with the prior art, since only the blocking strip 5 is pressed on the gap between the two glass substrates, the contact area with the inner wall of the glass mounting hole is reduced, thereby reducing the friction force. The adjusting sleeve 6 rotates circumferentially so that the plug column 1 always moves only vertically and will not be affected by forces in other directions, so that the blocking strip 5 is more accurately and tightly pressed on the gap and the plug column 1 is easier to insert and remove, so as to improve the processing efficiency and reduce the softened film from flowing into the glass hole.

[0019] By cooperating with the screw driver and the screw groove 32, the threaded rod 3 can be rotated to make the screw sleeve 4 move vertically along the threaded rod 3. During this period, the side arm 41 slides along the sliding hole 12, and the distance between the blocking strip 5 and the lower end surface of the plug 1 changes, so as to change the position of the sandwich gap when the thickness of the glass substrate changes.

[0020] In this embodiment, a disc-shaped bottom plate 21 is circumferentially spread out at the lower end of the seat tube 2. The bottom plate 21 can be pressed with fingers to ensure the stability of the bottom of the seat tube 2 when the adjustment sleeve 6 is rotated.

[0021] In this embodiment, two annular wear-resistant strips 7 are embedded and fixed on the side arm 41, and the two wear-resistant strips 7 are arranged in a mirror image with respect to the blocking strip 5. The two wear-resistant strips 7 are arranged in a mirror image with respect to the blocking strip 5, and can be tightly fitted and clamped with the inner wall of the glass installation hole, so that the upper and lower ends of the blocking strip 5 are both positioned, so that the blocking strip 5 is more accurately and tightly fitted and pressed on the gap of the film, and at the same time, the plug 1 can be stably installed in the installation hole of the laminated glass to prevent it from falling frequently due to looseness.

[0022] The thickness of the plug cap 11 is 10-20 mm, and the diameter of the plug cap 11 is 50-100 mm. Since the adjustment end 31 is embedded in the clearance groove 111, an extended support surface is formed on the upper end surface of the plug cap 11, so that before firing the kettle, when the laminated glass is fixed to the insertion rack, the plug cap 11 is set between two laminated glasses as a spacer, thereby reducing the processing steps.

[0023] The outer peripheral wall of the adjustment sleeve 6 is fixedly connected with a plurality of circumferentially extended turning handles 61. Since the glass mounting hole is relatively small, the adjustment sleeve 6 is relatively small in size, and it is relatively difficult to drive it to rotate through the friction between the hand and its peripheral surface. The circumferentially extended turning handles 61 are provided to change the force application point to achieve the purpose of reducing the rotation torque, making it easier to rotate the adjustment sleeve 6.

[0024] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
