Detailed Description

The following describes in detail an embodiment of the present invention with reference to fig. 1 to 6.

The embodiment is a magnet 2 toy, which is shown in the attached figures 1-3: comprises a copper pipe body 1 with an upper opening and a lower opening and a cylindrical magnet 2 which is vertically dropped and arranged in the pipe body 1. The length of the pipe body 1 is 50-150cm, so that people can observe the running condition of the magnet 2 within about 2-6s, and sufficient time can be provided for mastering corresponding data (such as the falling time, the falling speed, the acceleration and the like). The diameter of the magnet 2 is 1-5mm smaller than the inner diameter of the pipe body 1, so that the magnet 2 cannot rotate in the pipe body 1, the electromagnetic resistance of the magnet 2 is maximum, the descending speed of the magnet 2 can be minimum, and the observed effect is more obvious. The equal interval shaping of body 1 along circumference has four bar mouths 11 that run through 1 lateral wall of body, bar mouth 11 sets up along 1 length direction of body, bar mouth 11 is in 1 middle part of body. Because copper's body 1 is light-tight, can not see inside, just so can not see the position of magnet 2 in body 1 in real time, consequently the utility model discloses along circumference equidistant bar mouth 11 has been set up on body 1, through bar mouth 11 like this, just can see the position of magnet 2 in body 1 from a plurality of directions, made things convenient for the observation, so can see magnet 2 slowly whereabouts directly perceivedly, formed bright contrast with the free fall, reached a more magical phenomenon, just so more interesting. The width of the strip 11 is 1/6-1/4 of the inner diameter of the tube 1, so that the width of the strip 11 is sufficient to make it easy for a person to see the falling of the magnet 2 in the tube 1 and the position of the magnet 2. The distance from the upper end and the lower end of the strip-shaped opening 11 to the end part of the nearest pipe body 1 is 1-2cm, so that the material of the pipe body 1 cannot be wasted, and the blind area where the position of the magnet 2 cannot be observed cannot be too large.

Referring to figures 1, 2 and 4: the upper and lower pipe orifices of the pipe body 1 are connected with a plug 3 which can be disassembled to block the pipe orifices. The plug 3 for plugging the orifice of the pipe body 1 is arranged, so that the magnet 2 can not fall out of the pipe body 1 when falling to the lower end from the upper end in the pipe body 1, and the trouble of removing the pipe body by hand is avoided without removing the pipe body by hand. The plug 3 comprises a plug body 32 inserted into the pipe orifice and a cap body 31 integrally formed with the outer end of the plug body 32, wherein the diameter of the cap body 31 is 1-2cm larger than the outer diameter of the pipe body 1. The diameter of the cap body 31 of the plug 3 is 1-2cm larger than the outer diameter of the pipe body 1, when the plug 3 is removed, a user can easily frame the cap body 31 by hand, labor is saved when the plug 3 is pulled out, the plug 3 is easily pulled out of the pipe body 1, and the magnet 2 is convenient to take out. The plug 3 is made of rubber.

Referring to figures 1, 2, 5 and 6: the magnet 2 toy also comprises a positioning mechanism 4 for stopping the magnet 2 at any position in the pipe body 1. The positioning mechanism 4 comprises a fixing ring 41 sleeved outside the tube body 1 and a plurality of positioning portions 42 connected with the positioning ring, the positioning ring comprises a plurality of connecting bodies 411 and a plurality of connecting rings 412, and the number of the connecting bodies 411 and the number of the connecting rings 412 are the same as that of the strip-shaped openings 11. The connecting body 411 is connected with a connecting ring 412 at intervals, and the connecting ring 412 is formed with a through hole corresponding to the strip-shaped opening 11. The positioning portion 42 includes a positioning rod 421 having one end capable of moving axially along the through hole in the through hole and the strip port 11, a pressing cap 422 connected to the other end of the positioning rod 421, and a spring 423 sleeved on the positioning rod 421. One end of the spring 423 is bonded with the press cap 422, and the other end is bonded with the outer end of the connection ring 412. Set up positioning mechanism 4, when magnet 2 down drops from last in body 1, can make magnet 2 stop at the position that intraductal people wanted through positioning mechanism 4, positioning mechanism 4 is held to the hand, draw in finger extrusion pressure cap 422, locating lever 421 moves in to body 1, when magnet 2 falls on each locating lever 421, magnet 2 has just stopped on locating lever 421, open as the hand, locating lever 421 resets under spring 423's effect, magnet 2 can continue the whereabouts again, so can observe the condition (like speed) that magnet 2 two parts whereabouts about locating lever 421 locates in body 1, even can pass through the time-recorder record, so generally go on the analysis falling speed condition of data, the acceleration condition, just so can carry out deep research to magnet 2 at the internal motion of body 1, improve the student to the exploration ability of physical experiment.

The holding ring is formed for rubber material injection moulding, holding ring and 1 interference fit of body. So make fixed ring 41 just the same cover on body 1 of rubber ring, can push and pull fixed ring 41 with the hand for fixed ring 41 stops at body 1 upper corresponding position, does not need the hand to hold fixed ring 41 all the time and fixes positioning mechanism 4, has made things convenient for and has used positioning mechanism 4.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
