[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Embodiment 1
[0022] See also Figure 1-Figure 2 The utility model discloses an external fixing device for quickly and stably fixing a PVDF sheet material, comprising a positioning plate 1 and a placement groove 2, the placement groove 2 is arranged on the top surface of the positioning plate 1, a limiting tube 3 is installed on one side surface of the positioning plate 1, a limiting hole 4 is arranged on one side surface of the limiting tube 3, a partition plate 5 is installed on one side surface of the positioning plate 1, an anti-tilt component is installed on one side surface of the positioning plate 1, and an extrusion component is installed on the inner wall of the positioning plate 1.
[0023] There are four limiting tubes 3, which are evenly distributed on one side surface of the positioning plate 1 in a circular array. A limiting hole 4 is opened on one side surface of each limiting tube 3. There are four partitions 5, which are evenly distributed on one side surface of the positioning plate 1 in a circular array.
[0024] The anti-tilt assembly includes a rotating plate 6, a rotating shaft 7 is installed on the inner wall of the rotating plate 6, a torsion spring 8 is installed on the outer surface of the rotating shaft 7, a blocking plate 9 is installed on the top surface of the rotating shaft 7, and the rotating plate 6 is installed on one side surface of the positioning plate 1.
[0025] There are four rotating plates 6 respectively distributed on one side and the other side surface of the positioning plate 1, and a rotating shaft 7 is correspondingly distributed on the inner wall of every two rotating plates 6. The outer surface of the rotating shaft 7 is movably connected to the inner wall of the rotating plate 6, and a blocking plate 9 is correspondingly distributed on the outer surface of each rotating shaft 7. Two torsion springs 8 are correspondingly distributed on the outer surface of each rotating shaft 7.
[0026] When the PVDF sheet and the blocking plate 9 are no longer in contact, the torsion spring 8 under stress will reset and drive the rotating shaft 7 to rotate because the external force is small. When the torsion spring 8 drives the rotating shaft 7 to reset and rotate, the rotating shaft 7 will drive the blocking plate 9 to rotate on the inner wall of the rotating plate 6. The blocking plate 9 is rotated to its initial position through the driven rotation of the torsion spring 8, so that the blocking plate 9 can block the next PVDF sheet to prevent it from tipping over during installation.
[0027] Embodiment 2
[0028] Based on the above Example 1, please refer to Figure 3-Figure 5 , including an extrusion assembly including an extrusion plate 10, a handle 11 is installed on one side surface of the extrusion plate 10, a limiting rod 12 is installed on one side surface of the extrusion plate 10, an extrusion spring 13 is installed on the outer surface of the limiting rod 12, and the extrusion plate 10 is installed on the inner wall of the positioning plate 1.
[0029] The outer surface of the extrusion plate 10 is in active contact with the inner wall of the positioning plate 1 . There are two handles 11 equidistantly distributed on one side surface of the extrusion plate 10 . There are four limiting rods 12 equidistantly distributed on one side surface of the extrusion plate 10 in a circular array.
[0030] An extrusion spring 13 is correspondingly distributed on the outer surface of each limiting rod 12 , one end of the extrusion spring 13 is in active contact with one side surface of the positioning plate 1 , and the outer surface of the limiting rod 12 is in active contact with the inner wall of the limiting hole 4 .
[0031] When the extrusion plate 10 continuously pushes the PVDF sheet to move, the side of the PVDF sheet coated with glue will contact the wall surface, so that the PVDF sheet is fixed to the wall surface by glue, thereby realizing the fixed installation of the PVDF sheet. When the fixation is completed, the extrusion plate 10 is pulled backward by the handle 11. When the extrusion plate 10 moves on the inner wall of the positioning plate 1, the extrusion spring 13 squeezed on the outer surface of the limit rod 12 will push the limit rod 12 to move on the inner wall of the limit tube 3 due to the disappearance of the external force. By resetting the extrusion spring 13, the extrusion plate 10 and the limit rod 12 on the inner wall of the limit hole 4 are reset to the initial position, thereby facilitating the installation of the next PVDF sheet.
[0032] The working principle and use process of the utility model are as follows: when the PVDF sheet fixing device is needed, one side of the PVDF sheet to be installed is coated with glue, and when the coating is completed, the bottom surface of the PVDF sheet is aligned with the placement groove 2 opened on the top surface of the positioning plate 1, and the PVDF sheet is inserted into the positioning plate 1. When the PVDF sheet moves downward along the placement groove 2, its two sides will contact with one side surface of the blocking plate 9, and the blocking plate 9 at this time has a certain inclined angle, so as to block the PVDF sheet. After the placement is completed, the user holds the handle 11 installed on the surface of one side of the extrusion plate 10, and picks up the fixing device through the handle 11. Then move the fixing device to the wall surface where it needs to be installed, and make the partition plate 5 installed on one side of the positioning plate 1 contact with the wall surface. When it moves to the specified position, squeeze the extrusion plate 10. Because the partition plate 5 is fixedly connected to the positioning plate 1, when the extrusion plate 10 is forced to move, the positioning plate 1 contacts with the wall surface through the partition plate 5, so that the positioning plate 1 will not move with the extrusion plate 10. When the extrusion plate 10 moves, it will drive the limiting rod 12 installed on one side of the surface to move, and the limiting rod 12 is on the inner wall of the limiting hole 4 at this time. Therefore, when the extrusion plate 10 moves, it will drive the limiting rod 12 to move on the inner wall of the limiting hole 4, and because the limiting rod 12 An extrusion spring 13 is installed on the outer surface. When the extrusion plate 10 drives the limiting rod 12 to move, the limiting rod 12 will squeeze the extrusion spring 13, and the stressed extrusion spring 13 will be squeezed and contracted. At the same time, when the extrusion plate 10 moves, it will push the PVDF sheet on one side of its surface to move on the inner wall of the positioning plate 1. When the PVDF sheet moves, it will contact with one side surface of the blocking plate 9. Because of the extrusion force, the PVDF sheet will push the blocking plate 9, so that the blocking plate 9 drives the rotating shaft 7 to rotate on the inner wall of the rotating plate 6. When the rotating shaft 7 rotates, it will align with the torsion spring 8 installed on the outer surface and twist it, so that the torsion spring 8 is stressed, and when the extrusion plate 10 moves, the PVDF sheet will push the blocking plate 9. When plate 10 pushes the PVDF sheet to move to a certain distance, the rotation angle of the blocking plate 9 is too large, so it does not contact one side surface of the PVDF sheet. When the PVDF sheet and the blocking plate 9 are no longer in contact, the external force disappears, and the stressed torsion spring 8 will reset and drive the rotating shaft 7 to rotate. When the torsion spring 8 drives the rotating shaft 7 to reset and rotate, the rotating shaft 7 will drive the blocking plate 9 to rotate on the inner wall of the rotating plate 6. The torsion spring 8 drives the blocking plate 9 to rotate to the initial position, so that the blocking plate 9 can block the next PVDF sheet to prevent it from tipping over during installation.
[0033] When the extrusion plate 10 continuously pushes the PVDF sheet to move, the side of the PVDF sheet coated with glue will contact the wall surface, so that the PVDF sheet is fixed to the wall surface by glue, thereby realizing the fixed installation of the PVDF sheet. When the fixation is completed, the extrusion plate 10 is pulled backward by the handle 11. When the extrusion plate 10 moves on the inner wall of the positioning plate 1, the extrusion spring 13 squeezed on the outer surface of the limit rod 12 will push the limit rod 12 to move on the inner wall of the limit tube 3 due to the disappearance of external force. By resetting the extrusion spring 13, the extrusion plate 10 and the limit rod 12 on the inner wall of the limit hole 4 are reset to the initial position, thereby facilitating the installation of the next PVDF sheet.
