[0021] The following further describes the present application in detail Figures 1 - 3 with reference to the accompanying drawings.

[0022] The embodiment of the present application discloses a detachable sunken sewing machine platen. Referring to Figure 1 、 Figure 2 and Figure 3 , a detachable sunken sewing machine platen includes a base 1 and a platen body 3. Two symmetrically distributed U-shaped fixing frames 2 are fixed on the top of the base 1. The bottom of the platen body 3 is fixed with symmetrically distributed first U-shaped moving frame 4 and second U-shaped moving frame 5. The first U-shaped moving frame 4 and the second U-shaped moving frame 5 are respectively sleeved on the two U-shaped fixing frames 2 and have the freedom to move along the height of the U-shaped fixing frames 2;

[0023] A guiding groove 7 is penetrated and provided on one side of the second U-shaped moving frame 5. A bidirectional threaded rod 8 is rotatably connected between the two U-shaped fixing frames 2. One end of the bidirectional threaded rod 8 penetrates through the U-shaped fixing frame 2 and the guiding groove 7 and is fixed with a manual turntable 9. Two symmetrically distributed moving frames 10 are installed on the bidirectional threaded rod 8 through threads. Limiting blocks 12 are placed in both of the two moving frames 10. A pair of connecting rods 11 are fixed on both of the two limiting blocks 12. One ends of the two pairs of connecting rods 11 penetrate through the moving frames 10 and are installed with positioning nuts 13 through threads. Return springs 14 are sleeved on the two pairs of connecting rods 11. The return springs 14 are located between the limiting blocks 12 and the inner sides of the moving frames 10. A number of pairs of limiting grooves 6 for the limiting blocks 12 to be inserted are equally spaced on the first U-shaped moving frame 4 and the second U-shaped moving frame 5. A pair of installation grooves 16 for the limiting blocks 12 to be inserted are provided on both of the two U-shaped fixing frames 2. The width of the limiting block 12 is the same as the width of the first U-shaped moving frame 4, so that the limiting block 12 can be inserted into a pair of installation grooves 16 and a pair of limiting grooves 6 at the same time, which can increase the stability of the limiting block 12 and make it not easy to shake. By using the cooperation of the moving frame 10, the connecting rod 11, the limiting block 12, and the return spring 14, it is convenient for the limiting block 12 to reciprocate inside the moving frame 10. When adjusting the height of the limiting block 12, the user can directly lift the platen body 3 upward, and use the limiting groove 6 to squeeze the arc surface of the limiting block 12, so that the limiting block 12 can be disengaged from the inside of the installation groove 16 and the limiting groove 6 at the same time. Not only can the height of the platen body 3 be quickly adjusted, but by using the cooperation of the limiting block 12 and the limiting groove 6, the situation that the platen body 3 tilts during height adjustment can be prevented. And by using the provided return spring 14, it is convenient for the limiting block 12 to be inserted into the limiting groove 6, which is convenient for fixing the position of the platen body 3. Also, by rotating the manual turntable 9 counterclockwise, the two moving frames 10 can drive the two limiting blocks 12 to move at the same time, and it can also be disengaged from the inside of the installation groove 16 and the limiting groove 6 and prevent it from resetting. At this time, the position of the platen body 3 can be adjusted downward. After the adjustment is completed, by rotating the manual turntable 9 clockwise, the position of the platen body 3 can be fixed. And the detachable sunken sewing machine platen of the present application has a simple structure, is convenient for installation and processing, can also disassemble the platen body 3, and the installation and disassembly methods are simple and have good stability, which is beneficial to reducing production costs.

[0024] Refer to Figure 2 and Figure 3The outer wall of the two-way threaded rod 8 near the two moving frames 10 is threadedly installed with a limiting nut 15. When using this product, the two limiting nuts 15 can be rotated clockwise to make them fit tightly against the outer wall of the moving frame 10 to limit it and prevent it from sliding. When it is necessary to adjust the position of the table body 3 downward, the two limiting nuts 15 can be rotated counterclockwise to keep them away from the moving frame 10 to facilitate the adjustment of the position of the moving frame 10. The limiting nuts 15 can also be used to block the moving frame 10 to prevent it from escaping from the inside of the U-shaped fixing frame 2, thereby making it convenient for the user to use the two-way threaded rod 8 to adjust the use position of the moving frame 10.

[0025] Reference Figure 2 and Figure 3 The sum of the lengths of the limit block 12 and the connecting rod 11 is less than the length of the mobile frame 10, which facilitates the installation or removal of the limit block 12 and the connecting rod 11.

[0026] Reference Figure 2 and Figure 3 The length of the movable frame 10 is greater than the length of the U-shaped fixing frame 2 , which facilitates the position of the limiting block 12 away from the limiting groove 6 .

[0027] Reference Figure 2 and Figure 3 The materials of the movable frame 10, the limit block 12, the connecting rod 11 and the bidirectional threaded rod 8 are all metal materials, which are not easy to break or bend and are convenient to use.

[0028] The implementation principle of a detachable sinking sewing machine table in the embodiment of the present application is as follows: the user can directly lift the table body 3 upwards, and use the limiting groove 6 to squeeze the arc surface of the limiting block 12, so that the limiting block 12 can be separated from the installation groove 16 and the inside of the limiting groove 6 at the same time, which can not only quickly adjust the height of the table body 3, but also use the limited block 12 and the limited groove 6 to prevent the table body 3 from tilting when adjusting the height, and use the reset spring 14 to facilitate the insertion of the limiting block 12 into the limiting groove 6, so as to facilitate the position of the table body 3. The two limit blocks 12 can be moved simultaneously by rotating the manual turntable 9 counterclockwise, and can also be separated from the installation groove 16 and the inside of the limit groove 6 to prevent them from resetting. At this time, the position of the table body 3 can be adjusted downward. After the adjustment, the position of the table body 3 can be fixed by rotating the manual turntable 9 clockwise. The detachable sunken sewing machine table of the present application has a simple structure and is easy to install and process. The table body 3 can also be disassembled, and the installation and disassembly methods are simple, and the stabilizing effect is good, which is conducive to reducing production costs.
