Description

Technical Field

[0001] The present invention relates to the field of re-transfer card printer technology, and in particular to a door handle mechanism of a re-transfer card printer. Background Art

[0002] The retransfer card printer includes a set of ribbons and a set of retransfer films. It uses a digital heating head (TPH) with a multi-point heat source linear arrangement to heat the dye on the ribbon, and transfer the dye vaporization to the retransfer film by thermal sublimation. The retransfer film is then moved to the transfer area. The transfer area structure includes a heating roller module and a card drive roller mechanism. After the retransfer film is aligned with the card, the heating roller transfers the image on the transfer film to the card through pressure and heating.

[0003] The ribbon cassette and transfer film cassette of existing retransfer card printers are generally independent side-insertion structures, and the ribbon cassette and transfer film cassette are usually provided with door handles for easy pulling. The ribbon and transfer film are loaded into the ribbon cassette and transfer film cassette respectively, and a manual fixing mechanism is used to unlock and lock when loading and removing. The structure is complicated, resulting in cumbersome steps for loading and removing, which brings inconvenience to the operation.

[0004] Therefore, it is necessary to design a new technical solution to solve the above problems. Summary of the invention

[0005] In view of this, the present invention aims at the deficiencies in the prior art, and its main purpose is to provide a door handle mechanism for a re-transfer card machine, which realizes automatic unlocking and locking of the door hook, has a simple structure and is easy to operate.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A door handle mechanism of a re-transfer card machine comprises a rotatable door handle; the door handle is rotatable around a first axis;

[0008] It also includes a door handle turntable, a door hook, a door handle turntable spring and a door hook spring;

[0009] One end of the door handle turntable is provided with a first end face tooth, and one end of the door hook is provided with a second end face tooth. One end of the door handle turntable and one end of the door hook are meshed and spliced ​​through the first end face tooth and the second end face tooth to form a coaxial arrangement. The door handle turntable and the door hook are both rotatable around a second axial direction parallel to the first axial direction.

[0010] The door handle turntable spring is arranged at the other end of the door handle turntable to provide a restoring force for the door handle turntable to splice toward the door hook;

[0011] A circumferential tooth portion is arranged on the circumferential side of the door handle turntable, and a toggle head matched with the circumferential tooth portion is arranged on the door handle; the circumferential tooth portion has a forward rotation action surface and a reverse rotation action surface, and the reverse rotation action surface is arranged gradually higher along the reverse push direction of the toggle head toward the direction where the door hook is located;

[0012] The position corresponding to the second axial direction on the door hook is a rotation fulcrum, a hook portion is provided on one side of the door hook corresponding to the rotation fulcrum, and the door hook spring is provided on the other side of the door hook corresponding to the rotation fulcrum to provide a restoring force for the door hook to rotate around the rotation fulcrum;

[0013] When the door handle is turned forward, the toggle head on the door handle pushes the forward rotation surface of the circumferential teeth of the door handle turntable, causing the door handle turntable to rotate. The door handle turntable also drives the door hook to rotate, and the hook rotates with the door hook to achieve unlocking;

[0014] Continue to turn the door handle forward, the toggle head on the door handle will disengage from the circumferential teeth, and the door hook spring will cause the door hook to rotate and return to its original position;

[0015] When the door handle is rotated in the opposite direction, the toggle head on the door handle rotates along the reversing action surface of the circumferential tooth portion of the door handle turntable pushed by the toggle head, so that the door handle turntable moves in the direction away from the door hook until the toggle head on the door handle disengages from the circumferential tooth portion. The door handle turntable spring causes the door handle turntable to move and reset in the direction of the door hook, so that the first end face tooth remains meshed with the second end face tooth.

[0016] As a preferred solution, a plurality of circumferential tooth portions are evenly distributed along the circumference of the door handle turntable, and the forward rotation action surfaces and reverse rotation action surfaces of adjacent circumferential tooth portions are alternately arranged in sequence.

[0017] As a preferred solution, the door hook spring is a torsion spring, and the torsion spring is installed on the first hinge rod in the first axial direction of the door handle.

[0018] As a preferred solution, the toggle head has a forward rotation pushing surface and a reverse rotation guiding surface, the forward rotation pushing surface is a straight surface parallel to the first axial direction, and the reverse rotation guiding surface is an arcuate surface.

[0019] As a preferred solution, the forward-rotation action surface is a straight surface parallel to the second axial direction.

[0020] As a preferred solution, the door handle turntable and the door hook both have a hollow shaft hole, and the door handle turntable and the door hook are sleeved on a second hinged rod extending along the second axis, one end of the first hinged rod and the second hinged rod are installed on the first mounting plate, and the other end of the first hinged rod and the second hinged rod are installed on the second mounting plate, and the two ends of the door handle turntable spring respectively act between the first mounting plate and the other end of the door handle turntable.

[0021] As a preferred solution, the door handle turntable spring is sleeved on one end of the second hinged rod.

[0022] As a preferred solution, both the first mounting plate and the second mounting plate are provided with hinge rod mounting holes, and both ends of the first hinge rod and the second hinge rod pass through the hinge rod mounting holes of the corresponding first mounting plate and the second mounting plate respectively.

[0023] As a preferred solution, the first mounting plate and the second mounting plate are both bent to form an extension plate, and the extension plate is provided with a locking hole.

[0024] As a preferred solution, the hook portion has an insertion guide surface and a locking surface.

[0025] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0026] Mainly, a door handle, a door handle turntable, a door hook, a door handle turntable spring and a door hook spring are provided; when the door handle is rotated forwardly, the toggle head on the door handle pushes the forward rotation action surface of the circumferential tooth portion of the door handle turntable, so that the door handle turntable rotates, and the door handle turntable drives the door hook to rotate at the same time, and the hook rotates with the door hook to achieve unlocking; the door handle continues to be rotated forward, the toggle head on the door handle disengages from the circumferential tooth portion, and the door hook spring causes the door hook to rotate and reset; when the door handle is rotated reversely, the toggle head on the door handle rotates along the reverse rotation action surface of the circumferential tooth portion of the door handle turntable pushed by the toggle head, so that the door handle turntable is displaced in the direction away from the door hook until the toggle head on the door handle disengages from the circumferential tooth portion, and the door handle turntable spring causes the door handle turntable to displace and reset in the direction of the door hook, so that the first end face tooth remains meshed with the second end face tooth; the setting of the door handle mechanism realizes automatic unlocking and locking of the door hook, has a simple structure, eliminates the unlocking and locking of the manual fixing mechanism, simplifies the cumbersome steps of taking out or loading, and brings convenience to operation.
