The utility model relates to electric flame range technical field, concretely relates to a kind of probe structure of electric flame disc: including installation base, spring piece, installation cylinder and probe body, since installation base is welded on the bottom shell of electric flame disc, make structure stable, since installation cylinder is slidably arranged in installation base, and the elastic adjustment of probe body is realized by spring piece, effectively limit pot bottom height, prevent pot bottom directly cover nozzle, guarantee flame distribution uniform and heating efficiency, and probe body is big in upper and small in lower structure, cooperate with the taper gradual change section in installation cylinder, complete the installation of probe body, and by the setting of probe body, pot bottom temperature change can be detected in real time, by the detection of temperature change, it is convenient to realize the accurate regulation and control of temperature in each stage of cooking, also play the role of preventing dry burning, using the above structure, effectively solve the problem of single function of existing probe structure.

This invention relates to the field of highway paving technology and discloses a convenient highway and bridge paving construction device, including a support frame. Support frames are slidably connected to both ends of the outer wall of the support frame, and a lead screw is meshed with the top of the support frame. This invention addresses the problem of excessive damage to the concrete surface caused by a large difference in the moving speed between the bidirectional auger and the support frame when the equipment needs to retract. The device includes a moving mechanism and a sliding mechanism. When the equipment needs to retract, a motor drives a gear to rotate clockwise. The clockwise rotating gear drives a rack to slide upwards along the outer wall of a fixed track. The rack drives the U-shaped frame to move upwards synchronously, and also drives the sliding block and the bidirectional auger to slide upwards. This allows the bidirectional auger to be lifted when the equipment retracts, moving it away from the outer surface of the concrete and effectively preventing excessive wear on the outer wall of the concrete surface during retraction.

The utility model discloses a fire vehicle rolling slats door with hovering mechanism, include: fixed frame, rolling slats door body, fixed component and hovering subassembly, and the rolling slats door body sets up at the back of fixed frame, and fixed component includes the winding shaft of setting at the top of rolling slats door body, and the connecting place of winding shaft and fixed frame is provided with fixed part. The utility model discloses through the design of ratchet wheel, gap, pawl, springback piece and limiting piece, when in the opening of rolling slats door body, moving upwards to the rolling slats door body, first through the winding shaft drive ratchet wheel and rotate, pawl is pushed by the gap at this time, and the end of pawl does not contact with ratchet wheel, when needing the bottom of rolling slats door body and hover in a position, first make pawl be located at the position of gap, then pull down rolling slats door body, make pawl insert ratchet wheel, limit rolling slats door body and move upwards through ratchet wheel to the height of limiting door opening, avoid the situation of unable to close rolling slats door.
