SUMMARY OF THE INVENTION

To overcome the shortcomings, the present invention provides a pressing assembly of an embossing seat to mitigate or obviate the aforementioned problems.
The objective of the invention is to provide a pressing assembly of an embossing seal that can save labor in operation for improving the operation of the pressing assembly.
The pressing assembly has a frame, a first pressing handle, a second pressing handle, and a transferring module. The frame has a front end, a mounting recess, and two upright walls. The mounting recess is formed on the front end of the frame. The two upright walls are disposed at a spaced interval. Each upright wall has a transverse groove and a slanted groove, the transverse groove is formed through the upright wall above the mounting recess of the frame, and the slanted groove is formed through the upright wall above the mounting recess of the frame and located behind the transverse groove. The first pressing handle is pivoted on the frame and has a first pivot portion and a first shaft. The first pivot portion is pivoted on the frame. The first shaft is disposed across the two upright walls of the frame, is inserted through the transverse grooves of the two upright walls and the first pivot portion, and has an axis.
The second pressing handle is pivoted in the frame below the first pressing handle. The second pressing handle has a second pivot portion, a guiding groove, a second shaft, and a pushing member. The second pivot portion is pivoted in the frame and has a front section, a rear section, and a bottom surface. The guiding groove is formed through the rear section of the second pivot portion below the first pressing handle. The second shaft is disposed across the two upright walls of the frame, and is inserted through the second pivot portion of the second pressing handle. The pushing member is disposed below the front section of the second pivot portion and protrudes out of the bottom surface of the second pivot portion. The transferring module is pivoted on the first pressing handle, is coupled to the second pressing handle, and has a transferring element, a guiding pin, and a pushing pin. The transferring element is pivoted on the first pivot portion of the first pressing handle. The guiding pin is disposed on the transferring element, is inserted through the first pivot portion and the slanted grooves of the two upright walls, and has an axis. The pushing pin is disposed through the transferring element, is inserted through the guiding groove of the second pressing handle, and has an axis. A distance between the axis of the pushing pin and the axis of the guiding pin is longer than a distance between the axis of the guiding pin and the axis of the first shaft.
Furthermore, the pushing member has two pushing wheels. The two pushing wheels are disposed in the pushing member at a spaced interval.
Accordingly, a die assembly is disposed in the mounting recess of the frame. In operation, an object for embossing is inserted into the die assembly. The first pivot portion of the first pressing handle is pressed by a user and is pivoted. At the same time, the first shaft moves along the transverse grooves of the frame. The guiding pin moves along the slanted grooves of the frame. The pushing pin moves forward and moves along the guiding groove of the second pressing handle. The transferring element is pivoted and presses the second pivot portion. The second pivot portion is pivoted. The pushing member of the second pressing handle presses the die assembly to press the object. As the transferring element can be pivoted relative to the first pressing handle and with the arrangement of the transverse grooves, the slanted grooves, and the guiding groove, the first shaft, the second shaft, and the guiding pin are regarded as the torque fulcrums. A force applied to the first pivot portion can be efficiently transferred to a pushing force applied to the die assembly. The pushing force is increased by the pressing assembly for saving labor of the user. A reaction force applied to the user is decreased. The operation of the pressing assembly is smooth.
In addition, the uniformity in distribution of the pushing force is increased by the two pushing wheels. The stability and effect of embossing are increased, too.

With reference to Figs. 1 to 3, a pressing assembly of an embossing seal in accordance with the present invention comprises a frame 10, a first pressing handle 20, a second pressing handle 30, and a transferring module 40.
The frame 10 has a front end, a mounting recess 11, and two upright walls 12. The mounting recess 11 is formed on the front end of the frame 10. The two upright walls 12 are spaced at an interval. Each one of the two upright walls 12 has a transverse groove 13 and a slanted groove 14, the transverse groove 13 is formed through the upright wall 12 above the mounting recess 11 of the frame 10, and the slanted groove 14 is formed through the upright wall 12 above the mounting recess 11 of the frame 10 and located behind the transverse groove 13. The two transverse grooves 13 of the upright walls 12 are symmetrical and the two slanted grooves 14 are symmetrical. Furthermore, each one of the two upright walls 12 has a supporting portion 15. The supporting portion 15 is formed on and protrudes from an outer side of the upright wall 12, is located below the mounting recess 11, and has a top surface and a protrusion 151 formed on the top surface of the supporting portion 15.
The first pressing handle 20 is pivoted on the frame 10. The first pressing handle 20 has a first pivot portion 21 and a first shaft 22. The first pivot portion 21 is pivoted on the frame 10. The first shaft 22 is disposed across the two upright walls 12 of the frame 10, is inserted through the transverse grooves 13 of the two upright walls 12 and the first pivot portion 21, and has an axis.
The second pressing handle 30 is pivoted in the frame 10 below the first pressing handle 20. The second pressing handle 30 has a second pivot portion 31, a guiding groove 32, a second shaft 33, and a pushing member 34. The second pivot portion 31 is pivoted in the frame 10 and has a front section, a rear section, and a bottom surface. The guiding groove 32 is formed through the rear section of the second pivot portion 31 below the first pressing handle 20. The second shaft 33 is disposed across the two upright walls 12 of the frame 10, and is inserted through the second pivot portion 31 of the second pressing handle 30. The pushing member 34 is disposed below the front section of the second pivot portion 31 and protrudes out of the bottom surface of the second pivot portion 31. Furthermore, the pushing member 34 has two pushing wheels 35. The two pushing wheels 35 are disposed in the pushing member 34 at a spaced interval.
With reference to Figs. 2 to 4, the transferring module 40 is pivoted on the first pressing handle 20 and is coupled to the second pressing handle 30. The transferring module 40 has a transferring element 41, a guiding pin 42, and a pushing pin 43. The transferring element 41 is pivoted on the first pivot portion 21 of the first pressing handle 20. The guiding pin 42 is disposed on the transferring element 41, is inserted through the first pivot portion 21 and the slanted grooves 14 of the two upright walls 12, and has an axis. The pushing pin 43 is disposed through the transferring element 41, is inserted through the guiding groove 32 of the second pressing handle 30, and has an axis. A distance between the axis of the pushing pin 43 and the axis of the guiding pin 42 is longer than a distance between the axis of the guiding pin 42 and the axis of the first shaft 22.
With reference to Figs. 2 and 3, the transferring element 41 has two side portions 411 disposed at a spaced interval. The second pivot portion 31 is inserted between the two side portions 411. Furthermore, the pressing assembly has two rulers 50. The two rulers 50 are respectively disposed on the two upright walls 12 of the frame 10 and are symmetrical with each other. Each one of the two rulers 50 has a plate 51, a slot 52, and a stopper 53. The plate 51 is coupled to the frame 10 and has a top surface and a scale formed on the top surface of the plate 51. The slot 52 is formed on the plate 51. The stopper 53 is disposed on the plate 51 and is inserted into the slot 52. Moreover, the two rulers 50 are close to the mounting recess 11 of the frame 10.
With reference to Fig. 4, a die assembly 60 is disposed in the mounting recess 11 of the frame 10. The die assembly 60 has an upper die 61 and a lower die 62 below the upper die 61. The protrusions 151 are inserted into the lower die 62 of the die assembly 60 for retaining the die assembly 60. The top surfaces of the supporting portions 15 abut the lower die 62 of the die assembly 60 for increasing a contact area between the two upright walls 12 and the lower die 62 and increasing the embossing stability. When the pressing assembly is not operating, the first shaft 22 abuts rear ends of the two transverse grooves 13. The guiding pin 42 of the transferring module 40 abuts top ends of the two slanted grooves 14. The pushing pin 43 of the transferring module 40 abuts a rear end of the guiding groove 32 of the second pressing handle 30. The first pressing handle 20 lifts the second pressing handle 30 by the transferring module 40. The rear section of the second pivot portion 31 is inclined upwardly. One of the two pushing wheels 35 of the pushing member 34 abuts the upper die 61 of the die assembly 60.
With reference to Fig. 5, in operation, an object 70 for embossing is inserted between the upper die 61 and the lower die 62. A force is applied to the first pivot portion 21 of the first pressing handle 20. The first shaft 22 is regarded as the torque fulcrum. The first pivot portion 21 is pivoted with the first shaft 22. The first shaft 22 is rotated by the first pivot portion 21 and moves toward front ends of the two transverse grooves 13. The first shaft 22 further abuts the front ends of the two transverse grooves 13. The transferring element 41 is rotated by the first pivot portion 21. The guiding pin 42 moves along the two slanted grooves 14 and toward bottom ends of the two slanted grooves 14. The pushing pin 43 moves along the guiding groove 32 of the second pressing handle 30 toward a front end of the guiding groove 32. The transferring element 41 is pivoted relative to the first pivot portion 21. At the same time, a force applied to the second pivot portion 31 by the transferring module 40 is transferred from an oblique direction to a downward direction. The pushing member 34 of the second pressing handle 30 presses the upper die 61 of the die assembly 60 and applies a pushing force to the upper die 61 of the die assembly 60. The two pushing wheels 35 of the pushing member 34 press the upper die 61 simultaneously for increasing the uniformity in distribution of the pushing force applied to the upper die 61. The supporting portions 15 abut the lower die 62 for increasing the contact area between the two upright walls 12 and the lower die 62 and increasing the embossing stability. Thus, clearness of the embossing of the die assembly 60 is increased.
When the force is removed, the upper die 61 is restored and pushes the second pressing handle 30 upwardly. The transferring module 40 is pivoted by the second pressing handle 30 and drives the first pressing handle 20 to restore. The torque distance is increased by the pivot of the transferring module 40 in the restoring process. A reaction force applied to the first pivot portion 21 is decreased. A force applied to the user by the first pivot portion 21 is decreased, too.
Accordingly, the first shaft 22, the second shaft 33, and the guiding pin 42 are regarded as the torque fulcrums. The transferring module 40 is pivoted relative to the first pressing handle 20. The pushing pin 43 moves along the guiding groove 32 of the second pressing handle 20. The transferring module 40 is pivoted for adjusting the direction of the force applied to the second pivot portion 31 by the pushing pin 43. The force applied to the first pivot portion 21 can be efficiently transferred to the pushing force applied to the die assembly 60. The torque distance is adjusted by the transferring module 40 for increasing the pushing force, saving labor, and decreasing the reaction force applied to users. The operation of the pressing assembly is smooth.
In addition, the two pushing wheels 35 of the pushing member 34 press the upper die 61 simultaneously for increasing the pushing force and the uniformity in distribution of the pushing force. A pattern formed on the object 70 is clear. Therefore, the stability and effect of the embossing are increased by the two pushing wheels 35.
