[0020] See also Figure 1 - Figure 4 The utility model provides a technical solution: a clamping and fixing device with a double clamping and anti-running core function, including a lower shell 1, an upper shell 2 and an active cavity 4. The top of the lower shell 1 is connected to the upper shell 2 through a rotating shaft 3. The upper shell 2 can be moved through the rotating shaft 3 to realize the opening or closing of the upper shell and the lower shell. The active cavity 4 is arranged on the outer wall of one side of the lower shell 1. A connecting rod 5 is embedded in the top of the active cavity 4. The connecting rod 5 plays a connecting role. A limiting plate 6 is arranged at one end of the connecting rod 5, and the limiting plate 6 plays the role of a limiting spring 7.

[0021] The outer wall of the connecting rod 5 is sleeved with a spring 7, which rebounds after being compressed and contracted, and the spring 7 abuts against the limit plate 6. The end of the connecting rod 5 away from the limit plate 6 passes through the movable cavity 4 and is connected with a clamping strip 8, which plays a limiting role. Through the clamping strip 8, the outer wall of the side of the clamping strip 8 away from the connecting rod 5 is connected with an adjusting button 9, which plays an adjusting role. Pulling the adjusting button 9 can drive the connecting rod 5 and the clamping strip 8 to move horizontally outward.

[0022] The inner wall of the end of the card strip 8 is connected with a card block 10 by bolts, and a card slot 11 is provided on the outer wall of the upper shell 2 near the rotating shaft 3. The card slot 11 matches the card block 10, and the card block 10 is engaged with the card slot 11, so as to limit the card strip 8. A limiting groove 12 is provided on the outer wall of one side of the lower shell 1, and the card block 10 is embedded in the limiting groove 12. The limiting groove 12 can embed the card block 10 when the upper shell 2 and the lower shell 1 are opened, so as to play a storage role. When the upper shell 2 and the lower shell 1 need to be closed and clamped, the adjusting button 9 is pulled, and the connecting rod 5 and the card strip 8 can be driven to translate outward through the adjusting button 9, and the connecting rod 5 drives the limiting plate 6 to move, and the spring 7 With the extrusion and contraction of the limiting plate 6, the card strip 8 drives the card block 10 to move out of the limiting groove 12, and the adjusting button 9 is twisted to drive the card strip 8 to rotate along the connecting rod 5 as the center, and the card block 10 is moved to the corresponding position of the card slot 11, and the adjusting button 9 is released. Due to the resilience of the spring 7, the card strip 8 and the card block 10 move inward, so that the card block 10 is embedded in the card slot 11, and the fixed limit of the card strip 8 is realized. The card strip 8 can block the opening of the upper shell 2 and the lower shell 1, thereby realizing the clamping effect of the upper shell 2 and the lower shell 1 on the quilt core. When disassembling, pull the adjusting button 9 to move the card block 10 out of the card slot 11 and twist it to the limiting groove 12.

[0023] A protrusion 13 is provided on the inner wall of the side of the lower shell 1 away from the rotating shaft 3, and the top of the protrusion 13 is connected to a No. 1 clamping plate 14 by bolts, and the No. 1 clamping plate 14 plays a clamping role.

When the upper shell 2 and the lower shell 1 are closed and squeezed, the No. 1 plywood 14 and the No. 2 plywood 18 clamp and fix the quilt core to prevent the core from running. When facing a thicker quilt, the compression spring 17 contracts the movable block 16 to shrink into the fixed tube 15, so that quilts of different thicknesses can be clamped and fixed. At the same time, the setting of the compression spring 17 prevents the quilt from being excessively squeezed and crushed.

[0025] The inner wall of the lower shell 1 is provided with anti-skid patterns 19, which can increase friction. The middle part of the upper shell 1 is connected with a threaded cylinder 20 through a bearing. The bottom end of the threaded cylinder 20 is threadedly connected with a threaded rod 21.

When disassembling, pull the adjusting button 9 to move the card block 10 out of the card slot 11 and twist it into the limit slot 12. When the upper shell 2 and the lower shell 1 are closed and squeezed, the No. 1 clamping plate 14 and the No. 2 clamping plate 18 clamp and fix the quilt core to prevent it from running. When facing a thicker quilt, the compression spring 17 contracts the movable block 16 to retract into the fixed tube 15, so that quilts of different thicknesses can be clamped and fixed. By twisting the adjusting knob 24, the threaded tube 20 can be driven to rotate, and the rotation of the threaded tube 20 drives the threaded rod 21 to perform translational movement, and the threaded rod 21 drives the pressing plate 22 to squeeze the quilt core to prevent it from running. The quilt is clamped by the pressing plate 22, the No. 1 clamping plate 14 and the No. 2 clamping plate 18, so that the quilt is firmly fixed to prevent it from running. Even if the pressing plate 22 is loose, the quilt can be clamped by the No. 1 clamping plate 14 and the No. 2 clamping plate 18, thereby improving the clamping efficiency.
