Description

Technical Field

[0001] This utility model relates to the field of household sewing machine technology, specifically to an energy-saving household sewing machine motor foot pedal controller. Background Technology

[0002] Household sewing machines combine functions such as straight stitching, zigzag stitching, and buttonhole making. They are generally driven by human power (foot pedal or hand crank), but some are driven by electric motors.

[0003] For energy-saving foot pedal controllers for household sewing machines, refer to patent number CN214529632U, a plastic-cased foot pedal controller for household sewing machine motors that does not slip when used on tiles or floors and has good performance.

[0004] However, the above-mentioned household sewing machines do not have convenient movement and positioning functions when using the motor foot pedal controller. The foot pedal controller can only be placed in one location. The existing motor foot pedal controller is partially fixed by bolts. Due to different usage habits, it is not convenient to move and position the foot pedal when it is necessary to change its position after long-term use.

[0005] Therefore, we propose an energy-saving foot pedal controller for household sewing machine motors. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figures 1-4An energy-saving foot pedal controller for a household sewing machine motor includes a base frame 1. A foot pedal 2 is rotatably mounted on the upper surface of the base frame 1. Positioning boxes 3 are fixedly installed on both the left and right surfaces of the base frame 1. A moving groove 4 is opened on the outer surface of the positioning box 3. A silicone plate 5 is slidably mounted on the lower surface of the positioning box 3. Two silicone suction cups 6 are fixedly connected to the lower surface of the silicone plate 5. Two limiting rods 7 are fixedly inserted into the upper surface of the silicone plate 5. A fixing frame 8 is fixedly mounted on the lower inner wall of the positioning box 3. A rotating rod 9 is rotatably mounted between the front and rear inner walls of the fixing frame 8. A handle 10 is fixedly inserted into the outer surface of the rotating rod 9. Two eccentric wheels 11 are fixedly sleeved on the outer surface of the rotating rod 9. Two push plates 12 are slidably mounted on the lower inner wall of the positioning box 3. A sliding rod 13 is fixedly inserted into the lower surface of the two push plates 12. A spring 14 is fixedly connected between the lower surface of the two push plates 12 and the lower inner wall of the positioning box 3.

[0026] Specifically, through the cooperation between the base frame 1, foot pedal 2, positioning box 3, moving groove 4, silicone plate 5, silicone suction cup 6, limit rod 7, fixing frame 8, rotating rod 9, handle 10, eccentric wheel 11, push plate 12, sliding rod 13, and spring 14, the motor foot pedal controller can be conveniently positioned, and the suction cup can be firmly attached to the base plate in one step, improving the placement efficiency. The suction cup can also be deflated in one step, making it convenient to move the motor foot pedal controller.

[0027] In this embodiment: the handle 10 and the moving groove 4 are slidably arranged in correspondence; the upper surface of the silicone plate 5 is provided with a venting groove that communicates with the interior of the two silicone suction cups 6; and the lower surface of the positioning box 3 is provided with two first slots that are slidably arranged in correspondence with the two limiting rods 7.

[0028] Specifically, when the handle 10 drives the rotating rod 9 to rotate, the handle 10 rotates on the positioning box 3 through the moving groove 4.

[0029] In this embodiment: the lower surface of the positioning box 3 is provided with two second slots that are slidably arranged corresponding to the two slide rods 13, the protruding end of the eccentric wheel 11 is arranged corresponding to the push plate 12, and the slide rods 13 are sealed to the air vent grooves on the silicone plate 5.

[0030] Specifically, when the slide bar 13 moves downward, it seals the air vents on the silicone plate 5 and the silicone suction cup 6 through the second slot, and at the same time pushes the two suction cups downward to press and adhere tightly to the base plate.

[0031] Working principle: The foot pedal 2 on the base frame 1 controls the motor operation of the household sewing machine. The base frame 1 can be moved to a designated position as needed. Then, the base frame 1 is attached to the bottom plate, and the two silicone suction cups 6 at the bottom of the positioning boxes 3 on both sides are attached to the bottom plate. The handles 10 on both sides are then held and swung outwards from the foot pedal 2 via the moving groove 4 on the positioning box 3. The handles 10 drive the rotating rod 9 to rotate on the fixed frame 8. Simultaneously, the rotating rod 9 drives the two eccentric wheels 11 to push the push plate 12, compressing the spring 14 and simultaneously causing the sliding rod 13 to attach to the bottom silicone plate 5 through the second slot. The two sliding rods 13 seal the two venting grooves on the silicone plate 5. Then, the silicone plate 5 is pushed downwards, squeezing the two silicone suction cups 6 against the bottom plate. The pressure is applied by air pressure to clamp the positioning box 3 and the base frame 1, thereby positioning them. When the silicone plate 5 moves, it slides horizontally through two limit rods 7 and two first slots. The limit rods 7 limit the movement of the base frame 1 by using the first slots to prevent it from falling off. When the base frame 1 needs to be moved, the handles 10 on both sides are swung towards the foot pedal 2 on the positioning box 3 with the rotating rod 9 as the reference. The rotating rod 9 drives the eccentric wheel 11 to disengage from the push plate 12. The push plate 12 is pushed upward by the spring force of the spring 14, which drives the slide rod 13 to move upward and reset. The slide rod 13 disengages from the air vent on the silicone plate 5. The air pressure inside the silicone suction cup 6 at the bottom of the silicone plate 5 is discharged through the air vent, which releases the suction cup from the suction of the base plate, allowing the base frame 1 to be moved easily.

[0032] Example 2

[0033] Please see Figures 1-2 Based on Embodiment 1, this utility model provides a technical solution:

[0034] In this embodiment: the left and right surfaces of the foot pedal 2 are provided with slots 15, the left and right surfaces of the foot pedal 2 are slidably provided with baffles 16, the side of the baffle 16 near the foot pedal 2 is fixedly connected with a card plate 17, and the upper surface of the foot pedal 2 is fixedly connected with several rubber strips 18.

[0035] Specifically, the foot pedal 2 can be made non-slip by the cooperation between the slot 15, baffle 16, plate 17 and rubber strip 18. The baffles 16 on both sides prevent the foot from leaving the plane of the foot pedal 2 and improve the anti-fall-off performance.

[0036] In this embodiment: the card plate 17 and the card slot 15 are fitted together in a corresponding manner, and the inner wall of the card slot 15 is provided with a positioning groove that is engaged with the card plate 17 in a corresponding manner.

[0037] Specifically, the card plate 17 passes through the card slot 15 and then moves downwards into the positioning slot for engagement.

[0038] Working principle: When using the foot pedal 2 on the base frame 1, the foot steps on the rubber strip 18 on the foot pedal 2 to prevent slipping. The baffles 16 on both sides are inserted into the slots 15 through the clamping plates 17 and engaged with the positioning slots. This allows the two baffles 16 to be installed on the foot pedal 2, preventing the foot from tilting and falling off when moving on the foot pedal 2.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
