[0024] Please see Figure 1-3 This utility model provides a technical solution: a shoe upper anti-wrinkle stretching machine, characterized in that it includes;
[0025] The equipment body 10 has a limit member 20 connected to one end by a bolt thread. A main arc plate 21 is welded and fixed to one end of the limit member 20. A secondary arc plate 22 is provided on one side of the main arc plate 21, and the main arc plate 21 and the secondary arc plate 22 are symmetrical.
[0026] A secondary U-shaped limiting plate 35 is symmetrically welded and fixed to one end of the top of the main arc plate 21 and the secondary arc plate 22. A secondary threaded rod 33 is provided on one side of the secondary U-shaped limiting plate 35. One end of the secondary threaded rod 33 passes through the secondary U-shaped limiting plate 35 and extends into the interior of another secondary U-shaped limiting plate 35 and is welded and fixed thereto. The secondary threaded rod 33 is movably connected to the secondary U-shaped limiting plate 35 at the top of the main arc plate 21.
[0027] A main U-shaped limiting plate 23 is symmetrically welded and fixed to the top of the main arc plate 21 and the secondary arc plate 22. A drive shaft 25 is provided on the outside of one of the main U-shaped limiting plates 23. The drive shaft 25 passes through the main U-shaped limiting plate 23 at the top of the main arc plate 21 and is threadedly connected to it. One end of the drive shaft 25 extends into the interior of the main U-shaped limiting plate 23 at the top of the secondary arc plate 22 and is rotatably connected to it.
[0028] Furthermore, a secondary spring 34 is provided between the two secondary U-shaped limiting plates 35, and the secondary spring 34 is sleeved on the outside of the secondary threaded rod 33 and movably connected to it. The two ends of the secondary spring 34 are respectively attached to the inner walls of the two secondary U-shaped limiting plates 35.
[0029] Furthermore, a main spring 24 is provided between the two main U-shaped limiting plates 23, and the main spring 24 is sleeved on the outside of the transmission shaft 25 and movably connected to it. The two ends of the main spring 24 are respectively attached to the inner walls of the two main U-shaped limiting plates 23.
[0030] Furthermore, a main threaded rod 31 is symmetrically arranged on the outside of the drive shaft 25. One end of the main threaded rod 31 is welded and fixed to the main U-shaped limiting plate 23 at the top of the main arc plate 21, and a gear 30 is threadedly connected to the outside of the main threaded rod 31.
[0031] Furthermore, the gear 30 is meshed with the outer side of the transmission shaft 25, and a chain 32 is provided on the outer side of the gear 30, with one end of the chain 32 sleeved on the outer side of the gear 30 and rotatably connected to it.
[0032] Furthermore, one end of the auxiliary threaded rod 33 is threadedly connected to a locking device, and one end of the chain 32 is fitted onto the outside of the locking device and its threads.
[0033] Working principle:
[0034] When it is necessary to adjust the distance between the main arc plate 21 and the secondary arc plate 22, rotate the drive shaft 25 clockwise so that the drive shaft 25 is threadedly connected to the main U-shaped limiting plate 23 at the top of the main arc plate 21. When the drive shaft 25 is threadedly connected to the main U-shaped limiting plate 23 at the top of the main arc plate 21, it will tighten towards the inside of the secondary arc plate 22. When the main U-shaped limiting plate 23 at the top of the main arc plate 21 tightens, it will simultaneously compress the main spring 24.
[0035] When the drive shaft 25 is rotated, the gear 30 will mesh with the drive shaft 25, causing the gear 30 to rotate synchronously. When the gear 30 rotates, it will be driven by the chain 32. Through the transmission of the chain 32, the chain 32 will drive the clamp on the outside of the auxiliary threaded rod 33 to rotate synchronously.
[0036] When the clamp is threaded to the secondary threaded rod 33 on the outside of the secondary threaded rod 33, the secondary U-shaped limiting plate 35 at the top of the main arc plate 21 will tighten towards the drive shaft 25 at the top of the secondary arc plate 22, thus simultaneously squeezing the secondary spring 34 between the two secondary U-shaped limiting plates 35.
[0037] When the distance between the main arc plate 21 and the secondary arc plate 22 is adjusted, under the limiting of the secondary threaded rod 33 and the transmission shaft 25, the main spring 24 and the secondary spring 34 will expand outward synchronously so that the main arc plate 21 will be better limited.
[0038] Both main U-shaped limiting plates 23 have through holes at their bottoms, so that they will not affect the normal operation of the main body 10 during later use.
[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.
