[0024] To explain the technical content of the utility model, the purpose and effect realized in detail, the following is explained in combination with the embodiment and the drawing.

[0025] Please refer to Figure 1 And Figure 2 The utility model discloses a hole diameter limiter, including drive portion 1 and support portion 2, drive portion 1 has a drive end, support portion 2 with drive portion 1 as the center point is centrally symmetric and is slidably arranged on the drive end of drive portion 1.

[0026] Working principle: by drive portion 1 drive support portion 2 to support on the lateral wall of each layer glass 3 hole, to make each layer glass 3 between unable to happen relative displacement, to ensure that the coaxial degree of each layer glass 3 upper hole after high pressure piece.

[0027] Please refer to Figure 1 And Figure 3As shown, the drive unit 1 further includes a hydraulic chamber 11 and a piston 12 slidably disposed on the hydraulic chamber 11; the hydraulic chamber 11 has a hydraulic cavity 111, and the hydraulic chamber 11 is provided with a through hole 112 communicating with the hydraulic cavity 111, and one end of the piston 12 extends into the hydraulic cavity 111; the support unit 2 is slidably disposed on the hydraulic chamber 11 through the through hole 112.

[0028] As described above, during the vacuuming process, the vacuum bag will squeeze the piston 12 under the action of external atmospheric pressure, causing the piston 12 to continuously extend into the hydraulic chamber 111 of the hydraulic chamber 11. As a result, the liquid in the hydraulic chamber 111 will enter the through hole 112 to push the support part 2, so that the support part 2 can be supported on the side wall of the hole of each layer of glass 3.

[0029] Please refer to Figure 4 As shown, further, a compression plate 121 is provided on one end of the piston 12 that extends into the hydraulic chamber 111, and the side wall of the compression plate 121 abuts against the side wall of the hydraulic chamber 111.

[0030] As can be seen from the above description, the piston 12 uses the extrusion disc 121 to help quickly extrude the liquid in the hydraulic chamber 111 into the through hole 112.

[0031] Preferably, the extrusion disc 121 is a rubber disc, which facilitates the assembly of the piston 12 and the hydraulic chamber 11 and helps the liquid in the extrusion hydraulic chamber 11 to flow towards the through hole 112.

[0032] Please refer to Figure 1 and Figure 3 As shown, the driving part 1 is further provided with a guide tube 13 sleeved on the support part 2, and the guide tube 13 is connected to the through hole 112.

[0033] As can be seen from the above description, the direction of movement of the support part 2 can be ensured by the guide tube 13.

[0034] Please refer to Figure 3 As shown, the support portion 2 is further provided with a rubber stopper 21 that abuts against the side wall of the through hole 112.

[0035] As described above, the rubber stopper 21 is used to ensure the sealing of the through hole 112 and prevent liquid from leaking from the through hole 112.

[0036] Please refer to Figure 1 and Figure 3 As shown, the support part 2 further includes a top rod 22 and a limiting plate 23. The top rod 22 is slidably disposed on the driving end of the driving part 1, and the limiting plate 23 is disposed on the end of the top rod 22 away from the driving part 1.

[0037] As can be seen from the above description, the drive unit 1 drives the push rod 22 to move, so that the limiting plate 23 can abut against the side wall of the hole in each layer of glass 3.

[0038] Please refer to Figure 1 and Figure 3 As shown, further, the end face of the limiting plate 23 away from the driving part 1 is a convex arc-shaped surface.

[0039] As can be seen from the above description, the use of the curved surface allows the limiting plate 23 to better fit the sidewalls of the holes in each layer of glass 3.

[0040] Furthermore, the limiting plate 23 is detachably connected to the push rod 22. Preferably, the limiting plate 23 and the push rod 22 are threaded together.

[0041] As can be seen from the above description, since the limiting plate 23 is detachably connected to the top rod 22, the limiting plate 23 of the appropriate length can be quickly replaced according to the thickness of the laminated glass product, so that the limiting plate 23 can abut against the side wall of the hole of each layer of glass 3.

[0042] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
