Abstract
The utility model relates to a simple pendulum device with a magnet. The simple pendulum device comprises a fixed plate, a support plate, a rotating piece, a rope, a small ball and a magnet block; and the fixed plate comprises two sides which are respectively to be a front side and a back side, the support plate is fixedly connected with the front side of the fixed plate, the rotating piece penetrates through the support plate to be rotatablely connected with the support plate, one end of the rope is fixed on the rotating piece, the other end of the rope is connected with the small ball, and the magnet block is fixed at the back side of the fixed plate. The simple pendulum device with the magnet is fixed on a black board by the magnet block, and the black board is higher, so that students who even sit at the back can clearly see the demonstration process of the whole simple pendulum; and meanwhile, the rotating piece can be rotated clockwise or anticlockwise, so that the rope which is tied to the small ball is lengthened or shortened, the swing length of the simple pendulum is adjusted, and the students can more preferably understand the relationship between the swing period and the swing length of the simple pendulum.
Description
Technical field
The utility model relates to a kind of simple pendulum device, relates in particular to a kind of simple pendulum device of carry magnet.
Background technology
When demonstrating experiment with simple pendulum to the student, generally be that single pendulum is fixed on the iron stand, again iron stand is placed on the lectern, but such demonstration and inconvenient, because the presentation process that the limited feasible classmate who is sitting in the back of the height of lectern is difficult for seeing whole single pendulum.
The utility model content
The utility model is placed on the highly limited lectern at existing single pendulum apparatus for demonstrating, makes the classmate be sitting in the back be difficult for seeing that the deficiency of the presentation process of whole single pendulum provides a kind of simple pendulum device of carry magnet.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of simple pendulum device of carry magnet comprises fixed head, back up pad, tumbler, rope, bead and magnet piece; Described fixed head comprises two faces, be respectively front and back, fixedly connected between the front of described back up pad and fixed head, described tumbler passes back up pad and also and between the back up pad is rotationally connected, one end of described rope is fixed on the tumbler, the other end of described rope links to each other with bead, and described magnet piece is fixed on the back side of fixed head.
The beneficial effects of the utility model are: the simple pendulum device of the utility model carry magnet is fixed on the blackboard by magnet piece, because the aspect ratio of blackboard is higher, even make the classmate who is sitting in the back also can be clear that the presentation process of whole single pendulum, simultaneously, can be by clockwise or be rotated counterclockwise tumbler, make that to tie up to rope on the bead elongated or shorten, regulate the pendulum length of single pendulum, allow the student understand the hunting period of single pendulum and the relation between the pendulum length better.
Description of drawings
Fig. 1 is the structural representation one of the simple pendulum device of the utility model carry magnet;
Fig. 2 is the structural representation two of the simple pendulum device of the utility model carry magnet.
Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
Fig. 1 is the structural representation one of the simple pendulum device of the utility model carry magnet, and Fig. 2 is the structural representation two of the simple pendulum device of the utility model carry magnet.Shown in Fig. 1 and 2, the simple pendulum device of described carry magnet comprises fixed head 1, back up pad 2, tumbler 3, rope 4, bead 5 and magnet piece 6; Described fixed head 1 comprises two faces, be respectively front and back, fixedly connected between the front of described back up pad 2 and fixed head 1, described tumbler 3 pass back up pad 2 and and back up pad 2 between be rotationally connected, one end of described rope 4 is fixed on the tumbler 3, the other end of described rope 4 links to each other with bead 5, and described magnet piece 6 is fixed on the back side of fixed head 1.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
