Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0024] Such as figure 1 and figure 2 As shown, a spiral lifting device for teaching experiments includes a cylindrical fixed tube 1, one end of the fixed tube 1 is open, and the other end is closed. A lifting tube 2 is installed in the fixed tube 1, and the lifting tube 2 is also in the shape of a cylinder. The lifting tube 2 and the fixed tube 1 are in clearance fit, and the lifting tube 2 can slide axially in the fixed tube 1. During installation, one end of the lifting pipe 2 protrudes from the open end of the fixed pipe 1 and is fixedly connected with the connection plate 3 . The other end of the lifting tube 2 is threadedly connected to the outer wall of the transmission nut 4 located in the fixed tube 1; a locking sleeve 5 is installed at the opening end of the fixed tube 1, and one end of the locking sleeve 5 is fixed on On the fixed...

The invention introduces a spiral lifting device for a teaching experiment. The spiral lifting device comprises a fixed tube, wherein a lifting tube is installed in the fixed tube, and one end of the lifting tube extends out of the fixed tube and is fixed with a connecting plate while the other end of the lifting tube is in threaded connection with a transmission nut; a locking cover is installed at an opened end of the fixed tube, and one end of the locking cover is fixedly arranged on the fixed tube while the other end of the locking cover is hermetically connected with the lifting tube; the transmission nut is in threaded connection with a transmission lead screw, one end of the transmission lead screw passes through the fixed tube and is fixed with a crank, and the other end of the crank is fixedly provided with a handle; a circular bump is further formed on the transmission lead screw, a thrust ball bearing is further installed on the transmission lead screw, and the thrust ball bearing is located between the circular bump and the side wall of the fixed tube. The spiral lifting device provided by the invention has relatively strong teaching pertinence, and students can observe and understand actual equipment in the class in a pertinent manner. Moreover, the spiral lifting device is convenient to carry, good in using flexibility, convenient to maintain and relatively low in cost.
Description
technical field [0001] The invention relates to teaching experiment equipment, in particular to a spiral lifting device used for teaching experiment, which belongs to the technical field of teaching equipment. Background technique [0002] With the development of my country's economy and culture, technical talents are more and more valued and welcomed by enterprises. Therefore, the scale of various vocational colleges for training technical talents is also increasing, and the corresponding teaching methods and teaching experimental equipment are also being developed. Constantly updated. Among them, due to the large demand for talents in the field of construction machinery, for vocational schools of construction machinery, on the one hand, it is necessary to expand the enrollment scale, and on the other hand, it is necessary to improve teaching efficiency, so as to ensure the success rate of students. For example, the spiral lifting device on the mixer is frequently used equi...
