Description

Technical Field

[0002] After searching, application number 202321382622.6 discloses a fully enclosed ceramic heater, including a shell and a ceramic inner layer; the shell: a connecting head is provided at the left end of the outer side surface, and sliders are fixed on the upper and lower sides of the connecting head, the connecting head is located in the groove on the right side of the fixed seat, the slider is slidably connected to the slide groove on the surface of the fixed seat, a bracket is provided at the right end of the outer side surface of the shell, the ceramic inner layer is installed inside the shell, and heating wires are evenly fixed inside the ceramic inner layer.

[0003] During use, a fully enclosed ceramic heater in this patent application drives the bidirectional lead screw to rotate by rotating the wheel on the locking unit, forcing the second locking block to be stuck in the locking groove to fix the two brackets, and at the same time, the rotating bolt cooperates with the axial hole on the side of the connecting head to firmly fix the two shells. However, during such use, since the locking unit is independent of the outside of the device, the operation is cumbersome and easy to lose, and the two shells are slidably connected to the fixing seat through the sliders on the two connecting heads, resulting in a larger overall size of the device, which is not convenient for moving and storing, and brings inconvenience to the use of the device. For this reason, we propose a ceramic heater. Utility Model Content

At this time, the fixed threaded rod on the left is inserted into the synchronous slot on the fixed threaded rod on the right through the synchronous plug block to complete the connection. The connecting rotating rod is rotated and clamped in the fixed card slot. The hexagonal wrench is inserted into the hexagonal groove to drive the two fixed threaded rods to rotate synchronously. Since the threads on the two fixed threaded rods are in opposite directions, the two movable nut blocks threadedly connected to the two fixed threaded rods are forced to move away from each other, thereby driving the fixed stopper at the right end of the connecting rotating rod to conflict with the right wall of the movable nut block located on the right side, thereby completing the connection of the two fixed seats. The position between them is fixed, that is, the position of the two device shells is fixed; when multiple device shells need to be spliced, the connecting pin on the device shell is inserted into the connecting sleeve on the adjacent device shell, and the top of the connecting pin squeezes the stress inclined surface of the positioning rod inside the connecting sleeve through the force inclined surface, forcing the positioning rod to move to the outside of the connecting sleeve and cooperate with the reset baffle to compress the reset spring. When the positioning rod is aligned with the positioning socket, the positioning rod is inserted into the positioning socket under the elastic force of the reset spring to complete the fixation between the connecting pin and the connecting sleeve. The above operation is simple and practical, the structure is reasonable and compact, and the two device shells are separated for easy movement and storage, thereby improving the convenience of using the device.
