Description

Technical Field

[0001] This utility model relates to the field of seal technology, and in particular to a handle anti-rotation structure for a flip-top seal. Background Technology

[0002] Flip-top stamps, also known as self-inking stamps, are widely used in various fields due to their multifunctionality and convenience. Traditional flip-top stamps require pressing a handle to stamp, which is typically made of plastic and attached to a metal guide rod. During assembly, it is usually only glued to the stamp lifting frame. Over time, the handle may loosen, causing it to rotate around the guide rod during stamping. Eventually, the handle may detach from the guide rod, affecting normal stamping operations. Utility Model Content

[0003] To address the aforementioned problems, this utility model discloses a seal anti-rotation structure, which solves the problem in the prior art where the handle of a flip-top seal becomes loose after a long period of time, causing the seal to rotate when pressed.

[0004] The specific technical solution is as follows:

[0005] A seal anti-rotation structure includes a seal body, a lifting frame movably mounted on the seal body, a guide rod longitudinally penetrating the center of the lifting frame, and positioning holes on both sides of the guide rod at the top of the lifting frame. A handle is sleeved on the guide rod, the bottom of the handle is fitted against the top of the lifting frame, and protrusions corresponding to the positions of the positioning holes are respectively provided on both sides of the bottom of the handle. The two protrusions are respectively embedded in the two positioning holes.

[0006] Furthermore, the bottom center of the handle is provided with a groove, and the front and rear ends of the groove are set with openings. A locking piece is provided in the groove. The locking piece is sleeved on the guide rod and cooperates with the slot on the guide rod to realize the positioning of the lifting frame.

[0007] Furthermore, the bottom of the handle has protrusions on both sides of the groove, and the protruding pins are respectively set at the center of the two protrusions.

[0008] Furthermore, the positioning hole is circular, and the size and shape of the protruding pin are adapted to the size and shape of the positioning hole.

[0009] Furthermore, the protruding pin and the positioning hole are interference-fitted.

[0010] The beneficial effects of this utility model are reflected in:

[0011] This utility model has two positioning holes on the top of the seal lifting frame and protrusions corresponding to the two positioning holes on both sides of the bottom of the handle. The handle is fixed to the lifting frame by engaging the protrusions with the positioning holes. This solves the problem of loosening that is common with traditional handles that are fixed by adhesive. It also prevents the handle from rotating when pressed and eventually falling off.

[0018] Example 1

[0019] Please see the appendix Figure 1-3This embodiment provides a seal anti-rotation structure, including a seal body 1, a lifting frame 2 movably mounted on the seal body 1, a guide rod 3 longitudinally penetrating the center of the lifting frame 2, the lower end of the guide rod 3 being connected to the top of the seal body 1, and a positioning hole 21 being provided on each side of the top of the lifting frame 2 located on the guide rod 3, a handle 4 being sleeved on the guide rod 3, the bottom of the handle 4 being in contact with the top of the lifting frame 2, and two protruding pins 41 corresponding to the positions of the positioning holes 21 being provided on each side of the bottom of the handle 4, the two protruding pins 41 being respectively embedded in the two positioning holes 21 to fix the handle 4 to the lifting frame 2 and prevent the handle 4 from rotating on the guide rod 3.

[0020] In this embodiment, a groove 42 is provided at the center of the bottom of the handle 4. The groove 42 is open at both ends. An insertion hole 44 for accommodating the guide rod 3 is provided in the center of the groove 42. A locking piece 31 is provided in the groove 42. The locking piece 31 is sleeved on the guide rod 3. A locking tongue is provided on the inner side of the locking piece 31. A slot 32 is arranged longitudinally on the guide rod 3. By horizontally pushing the locking piece 31, the locking tongue is embedded into the slot 32, thereby achieving the positioning of the lifting frame 2.

[0021] In this embodiment, the bottom of the handle 4 has protrusions 43 formed on both sides of the groove 42, and protruding pins 41 are respectively provided at the center of the two protrusions 43.
