The demonstration of row conservation of mechanical energy, but the structure of some devices is more single, and certain deviation is will appear when being demonstrated, it is impossible to
Demonstration well, thus it is proposed that a kind of physics teaching law of conservation of mechanical energy apparatus for demonstrating.
Utility model content
It is above-mentioned to solve the purpose of this utility model is to provide a kind of physics teaching law of conservation of mechanical energy apparatus for demonstrating
The problem of being proposed in background technology.
To achieve the above object, the utility model provides following technical solution：A kind of physics teaching law of conservation of mechanical energy
Apparatus for demonstrating, including pedestal, the pedestal left end is equipped with left frame by bolt, and the left top of the trellis is installed with electromagnet, institute
It states left frame right side wall top and is fitted with left arc track, the middle part upper surface of the left arc track bottom end fitting pedestal is described
Left arc track right end is fitted with horizontal rail left end, and the horizontal rail right end is bonded right arc track left end, the pedestal
Right end is provided with slideway, and slide is slidably fitted in the slideway, and the slide upper end is equipped with right shelf, the right shelf by bolt
Left side wall upper end is fitted with right arc track, and the upper surface of fitting pedestal is slided in the right arc track bottom end.
Preferably, the horizontal rail is divided into four sections, and often section segmentation is independently installed.
Preferably, the horizontal rail bottom is integrally formed with pin.
Preferably, the raceway surface polishing treatment of the left arc track, horizontal rail and right arc track, and track connects
The place of connecing smoothly transits no protrusion.
Compared with prior art, the beneficial effects of the utility model are：Pass through left arc track and pair of right arc track
Claim setting, realize the unification of height, can effectively be demonstrated when carrying out energy conversion, become by the length of horizontal rail
Change, to demonstrate in entire energy conversion process the mechanical energy conserva-tion principle when noenergy consume, whole device changes and stability
Can be more preferable, play configuration more idealizes.

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
- 2 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of physics teaching law of conservation of mechanical energy demonstration
Device, including pedestal 1, the steady operation for whole device provides support, while the structure for upper part provides installation foundation, institute
It states 1 left end of pedestal and left frame 2 is equipped with by bolt, the installation support for electromagnet 3 and left arc track 4 provides benchmark, described
Left 2 top card of frame is equipped with electromagnet 3, inhales solid ball by the rank of electromagnet 3, releases ball after power-off, left 2 right side of frame
Wall top is fitted with left arc track 4, and the rolling for solid ball provides track restriction, left 4 bottom end of the arc track fitting
The middle part upper surface of pedestal 1, realizes the fixed installation of left arc track 4, and left 4 right end of arc track is fitted with horizontal rail
5 left ends, realize the connection of left arc track 4 and horizontal rail 5, while realize the extension of entire track length, the horizontal rail
5 right end of road is bonded right 6 left end of arc track, and 1 right end of pedestal is provided with slideway 9, and the slip for slide 8 provides space and limitation
Sliding trace is slidably fitted with slide 8 in the slideway 9, and the movement of right shelf 7 and right arc track 6 is realized by slip, described
8 upper end of slide is equipped with right shelf 7 by bolt, and the framework for right arc track 6 provides brace foundation, 7 left side wall of right shelf
Upper end is fitted with right arc track 6, and the upper surface of fitting pedestal 1 is slided in right 6 bottom end of arc track, realizes support function,
But without fixation.
Specifically, the horizontal rail 5 is divided for four sections, and often section segmentation is independently installed, realizes that horizontal rail 5 can be into
The adjusting of the multiple length of row.
Specifically, 5 bottom of horizontal rail often saved ensures that book review track 5 is pacified integrally formed with pin 10
