Specific implementation

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0022] Please refer to Figures 1 to 5 The utility model provides an embodiment: a liftable lockstitch machine foot pedal, including workbench 1, lockstitch machine 2 and power conversion box 6, lockstitch machine 2 is fixedly arranged on the upper end of workbench 1, power conversion box 6 is installed below lockstitch machine 2 and is connected through the mode of transmission, both sides of the bottom end of workbench 1 are fixedly provided with support frame 3, cross frame 4 is movably connected between the two support frames 3, one side of the upper end of cross frame 4 is hinged with foot pedal 5, the rear side of foot pedal 5 is fixedly connected with two symmetrical fixed seats 11, connecting rod 7 is connected between the two fixed seats 11, and one end of connecting rod 7 away from fixed seat 11 is in transmission connection with power conversion box 6.

[0023] The inside of one side fixed seat 11 is provided with movable cavity 1101, the inside of the other side fixed seat 11 is provided with limit groove 1102 corresponding to movable cavity 1101, limit rod 12 is movably connected in the inside of movable cavity 1101 and extends to the outside of fixed seat 11, the outer surface of one end of limit rod 12 in the inside of movable cavity 1101 is fixedly connected with limit plate 13, one side of limit plate 13 and the inner wall of movable cavity 1101 are fixedly connected with spring 14, and spring 14 is wound on the outer surface of limit rod 12, a plurality of limit holes 701 are equidistantly provided on the outer surface of connecting rod 7, one end of limit rod 12 extending to the outside of fixed seat 11 penetrates corresponding limit holes 701 in turn and is inserted with limit groove 1102.

[0024] By pulling the limiting rod 12, the limiting rod 12 drives the limiting plate 13 to move and extrude the spring 14 to compress, thereby driving the limiting rod 12 to disengage from the connection with the limiting groove 1102 and the limiting hole 701, and releasing the connection between the connecting rod 7 and the foot pedal 5. One of the fixed seats 11 is hinged with a clamping block 15 away from one side of the limiting groove 1102, and a clamping groove 1501 is formed on one side of the clamping block 15. The clamping groove 1501 is movably clamped on the outer surface of the limiting rod 12, and then the clamping block 15 is rotated to one side of the limiting rod 12, and the clamping groove 1501 on one side of the clamping block 15 is clamped on the outer surface of the limiting rod 12, so as to limit the movement of the limiting rod 12.

[0025] When the position of the foot pedal 5 is adjusted, the connecting rod 7 is placed between the two fixed seats 11, and then the clamping block 15 is rotated, so that the clamping groove 1501 on one side of the clamping block 15 is disengaged from the clamping on the outer surface of the limiting rod 12. At this time, the spring 14 releases the elastic force, and pushes the limiting rod 12 to penetrate through the corresponding limiting hole 701 on the surface of the connecting rod 7, and then is inserted into the limiting groove 1102, so as to connect the connecting rod 7, and facilitate the transmission between the foot pedal 5 and the power conversion box 6 after adjustment.

[0026] Both sides of the two support frames 3 close to each other are provided with driving grooves 301. A threaded rod 9 is rotatably connected to the inside of one side driving groove 301 through a handle 8, and a sliding rod 10 is fixedly connected to the inside of the other side driving groove 301. One end of the cross frame 4 is threadedly connected to the outer surface of the threaded rod 9, and the other end of the cross frame 4 is slidably connected to the outer surface of the sliding rod 10.

[0027] By rotating the handle 8 to drive the threaded rod 9 to rotate, the threaded rod 9 rotates while the thread drives one end of the cross frame 4 to threadedly rotate on the outer surface of the threaded rod 9. Through the sliding limiting of the other end of the cross frame 4 and the sliding rod 10, the cross frame 4 drives the foot pedal 5 to move up and down, so as to adjust the position of the foot pedal 5 according to the height and operation habit of different users.

[0028] When the flat sewing machine pedal is used, the limiting rod 12 is pulled to drive the limiting plate 13 to move and extrude the spring 14 to compress, thereby driving the limiting rod 12 to be separated from the limiting groove 1102 and the limiting hole 701, and the connection between the connecting rod 7 and the pedal 5 is released. Then, the clamping block 15 is rotated to be arranged on one side of the limiting rod 12, and the clamping groove 1501 on one side of the clamping block 15 is clamped on the outer surface of the limiting rod 12, so that the movement of the limiting rod 12 can be limited. Then, the user rotates the handle 8 to drive the threaded rod 9 to rotate, and the threaded rod 9 rotates while the thread drives one end of the cross frame 4 to rotate on the outer surface of the threaded rod 9, and the other end of the cross frame 4 is limited to slide with the slide rod 10, so that the cross frame 4 drives the pedal 5 to move up and down, thereby adjusting the position of the pedal 5 according to the height and operation habit of different users. Then, the connecting rod 7 is arranged between the two fixed seats 11, and then the clamping block 15 is rotated to drive the clamping groove 1501 on one side of the clamping block 15 to be separated from the clamping of the outer surface of the limiting rod 12. At this time, the spring 14 releases the elastic force, and drives the limiting rod 12 to penetrate through the limiting hole 701 corresponding to the surface of the connecting rod 7, and then is inserted into the limiting groove 1102, thereby connecting the connecting rod 7, so as to facilitate the transmission between the pedal 5 and the power conversion box 6 after adjustment.
