Description

Backward tilting foot switch of desktop sewing machine

Technical field:

The utility model relates to the technical field of switches, in particular to a backward tilting foot switch on a desktop sewing machine.

Background technique:

See accompanying drawing 1, shown in 2, the foot switch of existing desk-top sewing machine comprises foot pedal 10, pull rod 20, base plate 30, compression spring 40, and pull rod 20 is fixedly connected with foot pedal 10 by pin, foot The front end of the pedal 10 forms a rotational connection with the front end of the bottom plate 30, and one end of the compression spring 40 is sleeved on the boss 301 on the upper end surface of the bottom plate 30, and the other end is sleeved on the boss 101 on the lower end surface of the pedal 10. The two ends of the compression spring 40 are respectively fixedly connected with the boss 101 and the boss 301 by pins. This type of foot switch is forward-leaning, and the rear of the foot pedal is very high, which does not conform to ergonomics. According to the scientific principle, when the operator is operating, the feet are easily fatigued, which affects the work efficiency.

Invention content:

The purpose of the utility model is to provide a reclining foot switch conforming to the principle of ergonomics aiming at the deficiencies of the prior art.

The utility model is realized through the following technical scheme: the rear end of the foot pedal forms a rotational connection with the rear end of the base plate.

The foot pedal of the utility model is a backward tilting type, which can coordinate with people's feet, so that the operator is not easy to feel tired, and the work efficiency can be correspondingly improved accordingly.

Description of drawings:

Accompanying drawing 1 is the three-dimensional combination diagram of the forward-leaning type foot switch of the existing desktop sewing machine

Accompanying drawing 2 is the three-dimensional exploded view of the forward-leaning foot switch of the existing desktop sewing machine

Accompanying drawing 3 is the three-dimensional combination figure of the utility model

Accompanying drawing 4 is three-dimensional exploded view of the utility model

See accompanying drawings 3 and 4, the utility model includes: pedal 1, pull rod 2, base plate 3, compression spring 4, pull rod 2 and pedal 1 are fixedly connected by pin 5, and one end of compression spring 4 is sleeved on base plate 3 On the boss 31 on the upper end surface, the other end is sleeved on the boss 11 on the lower end surface of the pedal 1, and the two ends of the compression spring 4 are fixedly connected with the boss 11 and the boss 31 by pins respectively, and the pedal 1 A pair of downward earrings 12 are formed on both sides of the rear end of the pedal 1, and an upward connecting plate 32 is formed on the rear end of the base plate 3 corresponding to the position of the earrings 12. The earrings 12 are sheathed on both ends of the connecting plate 32 , and are rotatably connected to the connecting plate 32 through the pin shafts 5 passing through the through holes 121 , 321 provided on the earrings 12 and the connecting plate 32 .

Detailed ways:

After the utility model has been assembled as shown in accompanying drawings 3 and 4, the front end of the pedal 1 is tilted upwards. When the operator is operating, he only needs to make the pedal lean back and step on the pedal 1, and according to the seam plate It needs to step on the pedal 1 to get final product if it is turned on or off.
