Description

Technical Field

[0001] The utility model relates to the technical field of thermal transfer equipment, in particular to a handle driving mechanism and a manual heat press. Background Art

[0002] The hot press involved in this patent is a manual downward pressure hot press, which generally includes a machine base, a hot press plate assembly, a platform and a handle driving mechanism. A rotating arm is rotatably provided on the machine base, and the hot press plate assembly includes a hot press plate assembly; the handle driving mechanism includes a handle member, a pressure rod and a connecting rod. The lower end of the pressure rod is fixedly connected to the hot press plate assembly, and the upper end of the pressure rod slides through the rotating arm. The top end of the pressure rod is pivotally connected to the connecting end of the handle member, and the two ends of the connecting rod are pivotally connected to the connecting end of the handle member and the rotating arm. The connecting axes of the handle member, the connecting rod and the pressure rod are staggered. The handle member flips back and forth and synchronously drives the pressure rod to slide up and down, thereby driving the hot press plate assembly to move up and down relative to the platform.

[0003] Since the handle member is connected to the top end of the pressure rod by a pivotal connection, and the pressure rod is driven to move up and down by flipping forward and backward, in order to prevent the hot press plate assembly from remaining in the state of being raised or lowered to the maximum height, a positioning mechanism needs to be designed to limit the flipping of the handle member.

[0004] Chinese patent document CN213593920U discloses a manual downward pressure heat transfer machine, in which a bayonet is provided on the upper rear side of a pressure rod, and when the pressure rod flips backward and drives the pressure rod to slide upward to the maximum height, the rotating shaft between the pressure handle and the connecting rod can be inserted into the bayonet to form a positioning. This positioning structure requires the bayonet to be provided at the upper rear side of the pressure rod, which results in the structural strength and rigidity of the pressure rod being damaged, affecting the service life and stability of the product. Utility Model Content

[0005] The purpose of this patent is to overcome the problem in the prior art that when the hot pressing plate assembly is in the highest position, the positioning structure of the handle component needs to reduce material and set a slot on the upper rear side of the pressure rod, which causes the structural strength and rigidity of the pressure rod to be damaged, affecting the service life and stability of the product. The handle driving mechanism of the utility model is solved by setting a first limiting part on the side of the pivot axis of the connecting seat of the handle component and the two connecting rods close to the gripping part. When the handle component is flipped to make the connecting rod reach the highest position, the first limiting part is used to press against the surface of the pressure rod to realize the positioning of the handle driving mechanism.
