[0025] Please refer to Figure 1-Figure 2 The present embodiment provides a shock absorbing structure, which is arranged between the sewing machine body and the sewing machine table 10. The sewing machine table 10 is provided with a mounting groove 11 and a plurality of step grooves 12. The mounting groove 11 passes through the sewing machine table 10 and is used to be installed on the sewing machine body. The step groove 12 is arranged at the groove wall of the mounting groove 11, and the step groove 12 extends from the top surface of the sewing machine table 10 to the inside of the sewing machine table 10. The shock absorbing structure 20 includes:

[0026] A fixing seat 21 is arranged in the step groove 12;

[0027] The elastic member 22 is disposed on the fixing seat 21 , and the bottom end of the elastic member 22 abuts against the sewing machine table 10 , and the top end abuts against the bottom surface of the sewing machine body.

[0028] By arranging a shock-absorbing structure 20 at the mounting groove 11 of the sewing machine table 10 to support the sewing machine body, the sewing machine body is suspended on the sewing machine table 10, so that the weight of the sewing machine body and the vibration generated when the sewing machine body is working are absorbed by the elastic part 22 of the shock-absorbing structure 20 and then transmitted to the sewing machine table 10. Compared with the "rigid" shock-absorbing pad in the prior art, the shock-absorbing effect is better.

[0029] Optionally, there are at least two shock-absorbing structures 20, which is not limited in the present application.

[0030] Preferably, the shock absorbing structure 20 is two and symmetrically arranged at opposite ends of the mounting slot 11 on the sewing machine table 10;

[0031] Alternatively, there are three shock absorbing structures 20 and they are distributed in a triangular shape;

[0032] Alternatively, there are four damping structures 20 distributed at the four corners of the mounting slot 11 on the sewing machine table 10, such as Figure 2 This embodiment is further described by taking four shock absorbing structures 20 as an example.

[0033] Preferably, the fixing seat 21 is detachably arranged in the step groove 12. The detachable installation method can facilitate the installation and removal of the shock absorbing structure 20. Generally speaking, an oil pan is also provided at the bottom of the sewing machine body, so the detachable installation method can facilitate the placement and removal of the oil pan, that is, when installing, the oil pan is placed first, then the fixing seat 21 is installed, and finally the sewing machine body is installed. When disassembling, the sewing machine body is first removed, then the fixing seat 21 is removed, and finally the oil pan is removed. In addition, after the fixing seat 21 is installed, the oil pan can also be pressed and fixed.

[0034] Optionally, the detachable installation method includes but is not limited to designing the size of the step groove 12 to match the size of the fixing seat 21, and the fixing seat 21 can be directly placed in the step groove 12; or, the fixing seat 21 is fixed in the step groove 12 by means of a threaded connection or a snap connection, and the present application does not impose any restrictions on this.

[0035] Preferably, the top surface of the fixing seat 21 is not higher than the top surface of the sewing machine table 10 .

[0036] Preferably, when the top of the elastic member 22 abuts against the bottom surface of the sewing machine body, the top of the elastic member 22 is higher than the top surface of the fixing seat 21, that is, even when the elastic member 22 is in a compressed state, its top is always higher than the top surface of the fixing seat 21, so as to ensure that the weight of the sewing machine body and the vibration generated during operation can only be transmitted through the elastic member 22, thereby ensuring its shock-absorbing effect.

[0037] Preferably, the elastic member 22 is a spring. It should be understood that for the same fixing seat 21, the springs provided thereon may be one or more, and this application does not impose any restrictions thereon, and the springs may be designed according to the shock absorption requirements. At the same time, this application also does not impose any restrictions on the material, stiffness coefficient, and whether the spring is an equidistant spring.

[0038] Preferably, a receiving hole is provided on the fixing seat 21, and the bottom end of the spring passes through the receiving hole. The purpose of designing the receiving hole on the fixing seat 21 is to prevent the spring from bending in a direction perpendicular to the axial direction and to limit the deformation of the spring to ensure that the spring provides sufficient elastic support force.

[0039] Based on this, an embodiment of the present invention further provides a sewing device, including a sewing machine body, a sewing machine table 10 and a plurality of shock absorbing structures 20 as described above, wherein the sewing machine body is suspended on the sewing machine table 10 through the shock absorbing structure 20 .

[0040] Preferably, the shock absorbing structure 20 is two and symmetrically arranged at opposite ends of the mounting slot 11 on the sewing machine table 10;

[0041] Alternatively, there are three shock absorbing structures 20 and they are distributed in a triangular shape;

[0042] Alternatively, there are four shock absorbing structures 20 distributed at four corners of the mounting slot 11 on the sewing machine table 10 .

[0043] Preferably, the weight of the first end of the sewing machine body is greater than the weight of the second end of the sewing machine body, and the elastic supporting force provided by the shock absorbing structure 20 below the first end is greater than the elastic supporting force provided by the shock absorbing structure 20 below the second end. Generally speaking, the right side of the sewing machine body is heavier than the left side, so in order to achieve a better shock absorbing effect, the elastic supporting force of the shock absorbing structure 20 below the sewing machine body can be designed, and the elastic supporting force provided by the shock absorbing structure 20 below the right side of the sewing machine body is greater than the elastic supporting force provided by the shock absorbing structure 20 below the left side of the sewing machine body.

[0044] The elastic supporting force provided by the elastic member 22 can be changed by changing the material, quantity or number of windings of the elastic member 22, and the present application does not impose any limitation on this.

[0045] In summary, the embodiments of the present invention provide a shock-absorbing structure and a sewing device, by arranging a shock-absorbing structure 20 at the mounting groove 11 of the sewing machine table 10 to support the sewing machine body, so that the sewing machine body is suspended on the sewing machine table 10, so that the weight of the sewing machine body and the vibration generated when the sewing machine body is working are absorbed by the elastic part 22 of the shock-absorbing structure 20 and then transmitted to the sewing machine table 10. Compared with the "rigid" shock-absorbing pad in the prior art, the shock-absorbing effect is better.
