[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] See also Figure 1-6 The utility model provides a technical solution, a multi-layer fixture, wherein the top surface of the groove-shaped member 1 is evenly provided with a plurality of top holes 1.1 along its axial direction; the outer side wall of the groove-shaped member 1 is provided with a plurality of side holes 1.2 along its axial direction.
[0027] The square tube 2 is arranged in the inner cavity of the trough-shaped member 1; a plurality of upper through holes 2.1 are uniformly arranged on the top surface of the square tube 2 along the circumference, and lower through holes 2.2 are respectively arranged on the bottom surface of the square tube 2 at positions corresponding to the upper through holes 2.1.
[0028] The push-pull fixture 3 comprises a hollow base 3.1, an externally threaded sleeve 3.2 fixed to the bottom surface of the hollow base 3.1 and threadedly engaged with the top hole 1.1, a hinged frame 3.3 with its bottom end hinged to the front and rear walls of the hollow base 3.1, a handle 3.4 with its inner top hinged to the front and rear walls of the top inner cavity of the hinged frame 3.3, a vertical tube 3.5 hinged to its top end at the bottom inner end of the handle 3.4 and slidingly inserted into the hollow base 3.1 and the externally threaded sleeve 3.2, a nut 3.6 fixedly inserted into the bottom end of the vertical tube 3.5, a washer 3.7 fixed to the bottom surface of the nut 3.6, a bolt 3.8 with its top end threadedly engaged with the nut 3.6, and a spring 3.9 mounted on the outside of the bolt 3.8. The threaded portion of the bolt 3.8 slides into the upper through hole 2.1, and the top and bottom ends of the spring 3.9 are supported on the bottom surface of the washer 3.7 and the top surface of the square tube 2, respectively.
[0029] The inner side of the bottom end of the stopper 4 is provided with a lower retaining groove 4.1 that engages with the top end of the channel-shaped member 1. The outer wall of the bottom end of the stopper 4 is provided with a countersunk hole 4.3, and a bolt 4.4 is inserted into the countersunk hole 4.3 and threadedly engaged with the side hole 1.2. The inner side of the top end of the stopper 4 is provided with an upper retaining groove 4.2 that engages with the bottom end of the channel-shaped member 1.
[0030] The flexible strips 5 are respectively adhered to the bottom surface of the square tube 2 and the bottom surface of the inner cavity of the trough-shaped member 1. The flexible strips 5 are 2 mm thick silicone strips.
[0031] In summary, when assembling the multi-layer clamp, first thread the external threaded sleeve 3.2 into the top hole 1.1, install the bolt 3.8 from the lower through hole 2.2 and make its screw part pass through the upper through hole 2.1, then put the spring 3.9 on the screw of the bolt 3.8, and finally thread the top of the screw with the nut 3.6, so that the top and bottom ends of the spring 3.9 are respectively pressed against the bottom surface of the gasket 3.7 and the top surface of the square tube 2.
[0032] To clamp the plywood, place the two sheets to be glued together on the strip support. Use side strips to separate the edges of the sheets, and fill the space between the side strips and the edges of the sheets with adhesive tape. Clamp the clamps on either side of the sheet, clamping the edges between the bottom surface of the inner cavity of the channel 1 and the square tube 2. Pulling handle 3.4 downward moves vertical tube 3.5 and bolt 1 3.8 downward. Gasket 3.7, via spring 3.9, presses square tube 2 downward, forcing the flexible strip 5 on the bottom of the square tube 2 to fit tightly against the top surface of the sheet edges, thus securing the sheets.
[0033] When stacking multiple layers of sheet material, use bolt 2 (4.4) to install the stopper (4) on the top of the outer side of the corresponding channel-shaped member (1) of the next layer. Then, fit the outer bottom side of the corresponding channel-shaped member (1) of the previous layer into the upper retaining groove (4.2) of the stopper (4) of the next layer, and so on, to complete the stacking of multiple layers of sheet material. The clamped and stacked sheets are placed in a drying oven for heating, melting the adhesive tape between the sheets, and thus completing the gluing process of the two sheets.
[0034] After the boards are glued, each layer of board is removed from the clamp in order from top to bottom. When removing, just pull the handle 3.4 upward to move the square tube 2 upward, so that the edge of the board is released from the clamping effect, making it easier to remove the clamp from both sides of the board.
[0035] The operating principle of the push-pull clamp 3 is similar to that of the fast push-pull clamp in the prior art.
[0036] Bolt 1 (3.8) and bolt 2 (4.4) are both hexagon socket head bolts.
