[0060] The following is a specific embodiment of the present application, and the technical scheme of the present application will be further described in combination with the drawings, but the present application is not limited to these embodiments.

[0061] [Embodiment one]

[0062] As shown in a gauge mechanism, comprising: Figures 1-5

[0063] Sliding rod one 1, the front end portion is formed with a threaded fixed segment 11, the threaded fixed segment 11 is connected with a fastener 14, the sliding rod end and the fastener 14 form a fixed position 12 for fixing, in this embodiment, the fastener 14 is a nut or a cap.

[0064] Gauge, which is sleeved on the sliding rod one 1, is used for cooperating with the presser 5 to sew.

[0065] Among them, the upper end of the gauge is provided with a sliding hole 26, and a locking hole 23 is formed in the side surface, and the locking hole 23 leads to the sliding hole 26.

[0066] When the sliding rod one 1 is arranged in the sliding hole 26, the locking bolt 15 in the locking hole 23 is rotated, so that the end of the locking bolt 15 is pressed on the sliding rod one 1, thereby realizing the fixation of the gauge on the sliding rod one 1.

[0067] The gauge on the market is generally more cumbersome when installing, often also needs to use other tools to successfully complete the installation and disassembly action.

[0068] And in this technical scheme, the operator can set the sliding rod one 1 on the connecting portion 61 conveniently through the cooperation of the threaded fixed segment 11 on the sliding rod one 1 and the fastener 14.

[0069] The gauge can move along the sliding rod one 1, so as to realize the purpose of adjusting the distance between the gauge and the presser assembly 4.​

[0070] When the locking bolt 15 is screwed in the locking hole 23, the bottom end of the locking bolt 15 abuts against the sliding rod 1, limiting the movement of the gauge along the sliding rod 1 and fixing the position of the gauge, so that the distance between the gauge and the presser foot 5 of the presser foot assembly 4 is kept fixed, facilitating the operator to press the sewing material against the gauge and operate the sewing machine to sew flat stitches, improving the quality and appearance of the product.

[0071] As shown in Figures 1-5 the gauge comprises:

[0072] The sliding fixing seat 2 is provided with a sliding hole 26, the sliding rod 1 is arranged in the sliding hole 26, and the lower end surface of the sliding fixing seat 2 is recessed to form a connecting groove 21.

[0073] The gauge piece 3 is provided with an insertion part 31 at the upper end, and the insertion part 31 is provided with a movable hole 32 penetrating through the left and right side walls.

[0074] The sliding fixing seat 2 is also provided with a connecting hole 24, which leads to the connecting groove 21, and the connecting hole 24 is used to arrange a fixing part 25.

[0075] When the insertion part 31 is inserted into the connecting groove 21, the fixing part 25 is arranged to pass through the connecting hole 24 and the movable hole 32, so as to realize the movable installation of the gauge piece 3 on the sliding fixing seat 2.

[0076] The gauge piece 3 is connected with the sliding rod 1 through the sliding fixing seat 2, and when the sliding fixing seat 2 slides along the sliding rod 1, the movement of the gauge piece 3 can be driven, so as to facilitate the adjustment of the distance between the gauge piece 3 and the presser foot assembly 4.

[0077] In the embodiment, the movable hole 32 is a vertically arranged strip hole.

[0078] The fixing part 25 can move up and down along the movable hole 32, so that the gauge piece 3 can move up and down relative to the sliding fixing seat 2.

[0079] In the embodiment, the fixing part 25 is a pin, so as to facilitate the extension of the fixing part 25 into the connecting hole 24.

[0080] As a preferred embodiment, the fixing part can also be a bolt to fix the gauge piece 3 and the sliding fixing seat 2.

[0081] In actual sewing process, the thickness of the sewing material faced by different sewing work is different, and the gauge is used to limit the movement direction of the sewing material by allowing one end of the sewing material to abut against the gauge, so as to ensure the sewing of neat and beautiful stitches.

[0082] Specifically,Figure 4 As shown, when the presser foot 5 of the presser foot assembly 4 is pressed against the sewing material of different thickness, since the movable hole 32 is a strip-shaped hole, under the action of gravity, the gauge plate 3 can fall and be in contact with the sewing table, so that the operator can always press the sewing material against the gauge plate 3, and the contact area between the gauge plate 3 and the sewing material can be ensured, the fixing effect of the gauge plate 3 on the sewing material is improved, and the product quality and the adaptability of the sewing machine to different sewing work are improved.

[0083] Specifically as shown in Figure 4 and Figure 5 , the front-to-back length of the insertion part 31 is less than that of the connecting groove 21, so that after the insertion part 31 is installed into the connecting groove 21, the gauge plate 3 can swing front-to-back around the fixing part 25.

[0084] Thus, when the gauge plate 3 is connected with the sliding fixing seat 2, there is a gap between the front end face 34 of the insertion part 31 and the front inner wall of the connecting groove 21, so that the gauge plate 3 can swing relative to the sliding fixing seat 2.

[0085] Since when the sewing machine faces the sewing work of multi-layer sewing material, the thickness of the stacking part between the multi-layer sewing material is thicker than that of other positions. The existing gauge is easily affected by the uneven thickness of the sewing material, which hinders the normal movement of the gauge, and further affects the product quality and production efficiency.

[0086] Since the gauge plate 3 is movably connected with the sliding fixing seat 2, the gauge plate 3 can swing slightly.

[0087] Therefore, when the gauge plate 3 passes through the uneven-thickness sewing material, the front end of the gauge plate 3 is pushed up by the thicker sewing material. When the sewing material continues to move below the sliding fixing seat 2, the gauge plate 3 is pushed upward. So that the gauge plate 3 can always adhere to the sewing material and move smoothly, the operator can always press the sewing material against the gauge plate 3, the stability of the gauge plate 3 in the working state is ensured, and the product quality after sewing is improved.

[0088] Further, when the gauge plate 3 is connected with the sliding fixing seat 2, the left and right side walls of the insertion part 31 abut against the inner walls of the connecting groove 21. Thus, the insertion part 31 is limited to swing in the left and right directions, so that when the sewing material abuts against the gauge plate 3, the gauge plate 3 and the sliding fixing seat 2 are prevented from being deflected, the sewing effect is affected, and the stability of the gauge plate 3 in use is further improved.

[0089] Specifically as shown in Figures 2-5 , the sliding fixing seat 2 is further recessed and formed with a spring groove 22, and a pressing spring 27 is arranged in the spring groove 22.

[0090] When the gauge piece 3 is connected to the lower end of the sliding fixing base 2, the pressing spring 27 can press against the upper end of the gauge piece 3 and exert a downward force on the gauge piece 3, so that the lower end of the gauge piece 3 can stably fit on the sewing material.

[0091] The sliding fixing base 2 is provided with at least two spring grooves 22, which are arranged along the advancing direction of the gauge piece 3.

[0092] In the process of sewing the cloth, when the gauge piece 3 passes through the uneven sewing material, the front end of the gauge piece 3 will be lifted by the protrusions on the sewing material first. As the gauge piece 3 continues to move, the protrusions on the sewing material will move to the rear end of the gauge piece 3 and lift the rear end of the gauge piece 3.

[0093] And through the pressing spring 27 arranged in the spring groove 22, when the protrusions on the sewing material are no longer below the front end of the gauge piece 3, the pressing spring 26 in the front spring groove 22 on the sliding fixing base 2 will exert a force on the front end of the gauge piece 3, so as to ensure that the front end of the gauge piece 3 can always fit above the sewing material.

[0094] And when the rear end of the gauge piece 3 also passes through the protruding part on the sewing material, the pressing spring 2 in the rear spring groove 22 on the sliding fixing base 2 will also exert a force on the rear end of the gauge piece 3, so that the rear end of the gauge piece 3 can quickly fit on the sewing material.

[0095] Through the cooperation of the gauge piece 3 movably connected to the sliding fixing base 2 and the pressing spring 27, it is realized that in the sewing process, the front end and the rear end of the gauge piece 3 can stably maintain the state of fitting on the sewing material, so as to ensure the stability of the gauge piece in the sewing process, avoid the shaking of the sewing material, and achieve the purpose of improving the quality of the product.

[0096] Thus, it can be ensured that the gauge piece 3 can stably abut against the sewing table, so as to enable the user to fully abut the sewing material against the gauge piece 3 when performing the sewing work, thereby improving the limiting effect of the gauge piece 3 on the sewing material.

[0097] As shown in Figures 2-5 The front end of the gauge piece 3 is bent upward to become a guide part 33, which can make the gauge piece 3 pass through the sewing material more stably, further improving the adaptability and stability of the gauge piece 3 under different working conditions.

[0098] As a preferred technical solution, the other end of the sliding rod is shaped into a rotating part 13, which can drive the sliding rod to rotate.

[0099] As another preferred technical solution, the rotating part 13 can also be prismatic, so as to facilitate the user to drive the sliding rod to rotate, facilitate the user to screw the sliding rod to the connecting part 61, or disassemble the sliding rod from the connecting part 61.

[0100] As shown in Figures 1-7 a foot assembly with a gauge, comprising a foot assembly 4 and a gauge mechanism as described above, wherein the foot assembly 4 comprises:

[0101] a foot 5;

[0102] a connecting seat 6, the foot 5 is hinged at the lower end of the connecting seat 6.

[0103] As a preferred technical solution, a connecting part 61 is formed on the connecting seat 6, a mounting hole 62 is opened on the connecting part 61, and a fixing position 12 is further formed on the sliding rod 1, which can be rotatably arranged in the mounting hole 62.

[0104] The diameter of the fixing position 12 is smaller than the diameter of the rod part of the sliding rod 1, so that a stepped surface 16 is formed between the fixing position 12 and the rod part of the sliding rod 1. And the threaded fixing section 11 can pass through the mounting hole 62.

[0105] After the fixing position 12 passes through the mounting hole 62, the rod part of the sliding rod 1 cannot continue to enter the mounting hole 62, and the stepped surface 16 abuts against the side wall of the connecting part 61, limiting the position of the sliding rod 1, and also ensuring that the sliding rod 1 still has sufficient length for the sliding fixing seat 2 to move. Thus, the fastener 14 can be screwed on the threaded fixing section 11, and the sliding rod 1 is arranged on the connecting seat 6.

[0106] A lifting foot shaft connecting part 67 is further formed on the connecting seat 6, which connects the lifting foot shaft.

[0107] As shown in Figures 1-7 the connecting seat 6 is formed with an adjusting part 63, an adjusting bolt 64 is arranged through the adjusting part 63, and the lower end of the adjusting bolt 64 abuts against the rear end 51 of the foot 5.

[0108] The adjusting part 63 is further provided with a hanging part one 66, and the hanging part one 66 is connected with an elastic member 65. The other end of the elastic member 65 is connected with a hanging part two 52 on the rear end 51 of the foot 5, so that the rear end 51 of the foot 5 can always abut against the lower end of the adjusting bolt 64, achieving the purpose of fixing the position of the foot 5.

[0109] When the front end of the foot 5 moves from the position with thinner sewing material to the position with thicker sewing material in the case of sewing different thicknesses of sewing material, because the thickness of the sewing material changes, the front end of the foot 5 will be lifted up, and then the rear end 51 of the foot 5 will swing down. After the front end of the foot 5 is lifted up, it can ensure that the foot 5 can smoothly pass through the sewing material with uneven thickness.

[0110] And since the rear end 51 of the presser foot 5 and the adjusting part 63 of the connecting seat are connected through the elastic member 65, when the front end of the presser foot 5 passes the position where the sewing material is thick, the front end of the presser foot 5 is no longer lifted by the sewing material, and the rear end 51 of the presser foot 5 is lifted upward by the elastic member 65, so that the front end of the presser foot 5 is pressed downward again, thereby ensuring that the presser foot 5 can be stably pressed against the upper end of the sewing material.

[0111] By changing the position of the adjusting bolt 64, the angle of the front end of the presser foot 5 being lifted upward can be limited.

[0112] And by the cooperation of the elastic member 65 and the adjusting bolt 64, the lower end surface of the presser foot 5 and the workbench surface can be kept parallel, so that the presser foot 5 can be pressed against the upper surface of the sewing material evenly, thereby ensuring that the presser foot 5 can effectively press the sewing material.

[0113] In the embodiment, the hanging part one 66 and the hanging part two 52 are integrally formed on the presser foot 5, and the elastic member 65 is a spring, the two ends of which are connected to the hanging part one 66 and the hanging part two 52.

[0114] As another preferred technical solution, a screw can be connected to the adjusting part 63, and the end of the screw is formed as the hanging part one 66,

[0115] or,

[0116] the hanging part one 66 and the hanging part two 52 are screws or rivets installed on the adjusting part 63 and the presser foot 5.

[0117]

[0119] The sliding rod two 7 is formed with a threaded groove 71, which can cooperate with the threaded fixing section 11 to connect the sliding rod one 1 and the sliding rod two 7.

[0120] When the fixing position 12 of the sliding rod one 1 is located in the mounting hole 62, the sliding rod one 1 and the sliding rod two 7 are screwed together, thereby realizing the installation of the sliding rod one 1 and the sliding rod two 7 on the left and right sides of the connecting part 61 respectively.

[0121] And the sliding rod one 1 and the sliding rod two 7 are both provided with a regulating piece.

[0122] Since the regulating piece provided on the sliding rod two 7 and the regulating piece provided on the sliding rod one 1 have the same structure, only the position and direction are different, and therefore the specific structure of the regulating piece provided on the sliding rod two 7 will not be described further.
