The two aluminum alloy templates are connected through the fixing openings by the fixing device. The utility model has a reasonable structure, a stable structure, and is simple to operate. It not only realizes the rapid clamping of the aluminum alloy templates, but also makes the connection between the two adjacent aluminum alloy templates more compact through the labor-saving lever.

[0004] However, the above-mentioned prior art still has the following deficiencies when used: 1. The clamping device disclosed therein is inconvenient to use.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 3 The utility model provides a technical solution: an aluminum alloy template clamping mechanism, including a clamping device 1 and two aluminum alloy plates 2, the aluminum alloy plates 2 are provided with clamping holes 21, and the two aluminum alloy plates 2 are fastened and connected through the clamping holes 21 and the clamping device 1.

[0023] In the present technical solution, the clamping device 1 includes a plug-in tube 11, an annular pad 12, a transmission shaft 13 and a pry rod 14. A limit plate 111 is fixedly sleeved on the plug-in tube 11 near one end. The outer diameter of the plug-in tube 11 is approximately equal to the inner diameter of the clamping hole 21, and the outer diameter of the limit plate 111 is larger than the clamping hole 21.

[0024] The annular gasket 12 is sleeved on the plug-in tube 11 in a gap and is detachably connected. When in use, the limit plate 111 and the annular gasket 12 are located at the opposite side of the connection portion of the two aluminum alloy plates 2.

[0025] Parallel and coaxial eccentric disks 131 are fixedly connected to both ends of the transmission shaft 13, the pry bar 14 is connected to the middle part of the transmission shaft 13 and the two are vertically arranged, and the outer peripheral wall of the plug-in tube 11 is provided with a U-shaped groove 113 close to the other end and with a clearance fit with the transmission shaft 13. That is to say, after the transmission shaft 13 is placed in the U-shaped groove 113, the pry bar 14 is manually held and then swung to drive the eccentric disk 131 to rotate. At this time, the eccentric disk 131 utilizes the eccentric characteristic to squeeze the annular pad 12. At this time, the distance between the limit plate 111 and the annular pad 12 is reduced and the two aluminum alloy plates 2 are clamped. In addition, this arrangement makes the use of the clamping device 1 of the present application without too many installation steps, and is more convenient to use. It also utilizes the lever principle, and the clamping force is stronger.

[0026] Furthermore, an anti-loosening recess 1131 is provided at the top of the U-shaped groove 113 . When the transmission shaft 13 is subjected to force, it will be limited by the anti-loosening recess 1131 , thereby preventing the transmission shaft 13 from escaping from the anti-loosening recess 1131 .

[0027] In this embodiment, the outer peripheral wall of the plug-in tube 11 is provided with a notch 112 located at the top and connected to the U-shaped groove 113. The center of the eccentric disk 131, the axis of the transmission shaft 13 and the axis of the pry bar 14 are in the same plane. The center of the eccentric disk 131 and the pry bar 14 are located on both sides of the transmission shaft 13. That is to say, when the eccentric disk 131 is in a state of pressing the annular pad 12, the pry bar 14 is in a state close to being coaxial with the plug-in tube 11. This arrangement facilitates the pry bar 14 to be in a state where no interference risk is caused.

[0028] Furthermore, the pry bar 14 is provided through the transmission shaft 13 and the two are slidably matched. After the pry bar 14 slides into the plug-in tube 11, it will be hidden in the plug-in tube 11, which not only reduces the space occupied by the pry bar 14, but also the plug-in tube 11 will limit the pry bar 14. When disassembly is required, the two aluminum alloy plates 2 can be easily disassembled by pulling out the pry bar 14 and then swinging it in the opposite direction.

[0029] Furthermore, a guide sleeve 132 is welded to the middle of the transmission shaft 13 and is sleeved on the outside of the pry bar 14. A baffle 141 is welded to one end of the pry bar 14. A return spring 142 is sleeved on the pry bar 14 and is located between the guide sleeve 132 and the baffle 141. The return spring 142 prevents the pry bar 14 that has entered the plug-in tube 11 from sliding outward. Under the action of the return spring 142, the baffle 141 will press against the inner wall of the plug-in tube 11.

[0030] In this embodiment, a pull ring 143 is welded to the other end of the pry bar 14 , and the pull ring 143 serves as a hand-held component for manually operating the pry bar 14 .

[0031] In this embodiment, anti-skid threads 121 are provided on both sides of the annular pad 12 . The function of the anti-skid threads 121 is to increase the friction between the eccentric disk 131 and the annular pad 12 .

[0032] Working principle: fit the two aluminum alloy plates 2 at the positions where they need to be docked, and ensure that the snap-in holes 21 of the two are aligned, then use the plug-in tube 11 to insert it from one snap-in hole 21 and extend it from the other snap-in hole 21, put the annular pad 12 onto the plug-in tube 11, and then hold the pry bar 14 to put the transmission shaft 13 into the U-shaped groove 113, the reset spring 142 is in a compressed state, and the eccentric disk 131 is located on one side of the annular pad 12. At this time, manually hold the pry bar 14 and swing it, the eccentric disk 131 squeezes the annular pad 12, and the distance between the annular pad 12 and the limit plate 111 is reduced and clamps the two aluminum alloy plates 2. At this time, the pry bar 14 is in a state of being nearly coaxial with the plug-in tube 11. After releasing the pry bar 14, the reset spring 142 stretches and drives the pry bar 14 to hide in the plug-in tube 11. It should be noted that the annular pad 12 can be added as needed.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
