Background technology

It is a kind of motion demonstrating equipment that flat throwing, which erects instrument, and its structure is：Including substrate 11, riser 7, weight 8, release ball plate 6 With metal ball 9, riser is installed in the side edge of substrate, and riser installs two rotations towards the surface upper end interval on the outside of substrate Axle 4, the rotary shaft of side, which is installed, releases ball plate, releases the side of ball plate lower end two and is provided with two symmetrical metal columns, each metal A metal ball is set with post 10, the rotary shaft of opposite side installs swing rod, and weight is installed in the lower end of swing rod.In use, by swing rod to Eminence rotation, then looses one's grip, and swing rod drives weight release ball plate up to knocking to releasing ball plate and move, releases ball plate and is knocked rear rotation, Metal ball away from weight flies out and makees level throw motion laterally in the case where releasing the promotion of ball plate, another metal ball release ball plate to Dropped during eminence rotation from metal column and make the movement of falling object, student can observe the process of two metal ball motions, fall Time fallen etc., there is Railway Project in said structure：1. substrate is placed on table edge, it is difficult to keep horizontality, causes to put down Throw deviation during with the movement of falling object；2. a hand steered firmly substrate is needed when using, another hand rotation swing rod, operation is not Just；3. student can only observe whether two metal balls are to land simultaneously, specific data when being moved for the two can not be intuitively See, teaching efficiency is bad.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art to be landed there is provided that can adjust substrate level degree, detection When stressing conditions and run time a kind of level throw motion and the comparison device of the movement of falling object.

The utility model is adopted the technical scheme that：

A kind of level throw motion and the comparison device of the movement of falling object, including substrate, riser, weight, release ball plate and metal Riser is installed in ball, the side edge of substrate, and riser sets towards the surface upper end on the outside of substrate and releases ball plate and swing rod, releases ball plate Lower end both sides set two metal balls, and weight is installed in the lower end of swing rod, it is characterised in that：The substrate is sleeved on a fixture upper end Guide pillar on, set on the substrate on the outside of the guide pillar and installed on multiple adjustment bolts, substrate a cross level meter, it is described to release ball plate Limit switch is installed on riser between swing rod, the output end of the limit switch connects a central control module, center control Molding block connects a Keysheet module and display module, and the central control module is also connected with one and is arranged on below metal ball on ground The output end of pressure sensor.

Moreover, the fixture is a bending card frame, one clamping screw is set in bending card frame lower end.

Advantage of the present utility model and good effect are：

In the utility model, bending card frame is fixed on the edge of desk by clamping screw, without with it is hand steered live, and Guide pillar plays a part of guiding, and four adjustment bolts of guide pillar side are used for the level for adjusting substrate, when ball plate is released in weight shock, Ball plate rotation is released, limit switch is discharged and exports a signal, the signal, which is transported to after central control module, starts timing, two Individual metal ball does level throw motion and the movement of falling object, after the two strikes the pressure sensor that ground contraposition is set, produces Signal be transported to central control module, stop timing, the quality of metal ball, the height away from ground are known variables, then coordinated Run duration can calculate the data such as speed, and these data that are known and calculating are shown on display module, very Intuitively, while can show for information such as the formula of calculating, teaching efficiency is improved.

Embodiment

With reference to embodiment, the utility model is further illustrated, following embodiments are illustrative, be not limited , it is impossible to protection domain of the present utility model is limited with following embodiments.

A kind of level throw motion and the comparison device of the movement of falling object, as shown in Figure 1, 2, 3, including substrate 11, riser 7, Weight 8, release ball plate 6 and metal ball 9, riser is installed in the side edge of substrate, and riser is set towards the surface upper end on the outside of substrate Put and release ball plate and swing rod, release ball plate lower end both sides and two metal balls are set, weight, wound of the present utility model are installed in the lower end of swing rod It is newly：The substrate is sleeved on the guide pillar 13 that the upper end base 14 of a fixture 16 is filled, and is set on the substrate on the outside of the guide pillar Installed on multiple adjustment bolts 12, substrate and install spacing on a cross level meter 21, the riser released between ball plate and swing rod Switch 22, the output end of the limit switch connects a central control module 3, the central control module connection He of one Keysheet module 2 Display module 1, the central control module is also connected with the output end of a pressure sensor 20 being arranged on the ground of metal ball lower section.

In the present embodiment, four adjustment bolts are set at the corner of substrate, cross level meter be arranged on riser and guide pillar it Between substrate on.The fixture is a bending card frame, and a clamping screw 19 is set in the sleeve pipe 18 of bending card frame lower end.

When the utility model is used：

1. unscrewing clamping screw, bending card frame is stuck at table edge 17, clamping screw is tightened, it is withstood desk side Edge；

2. substrate is enclosed within guide pillar, tightens respectively, unscrew four adjustment bolts, by the external diameter of guide pillar is less than substrate institute The internal diameter of drilling, the top pressure bending card frame upper surface of adjustment bolt lower end 15 gradually makes the bubble of cross level meter be located at middle Afterwards, horizontal adjustment is finished；

3. being set with two metal balls in two metal columns for releasing ball plate, swing rod is grasped, makes its rotation rise to the right, Hand is unclamped, swing rod is swung to ball plate is released, final weight, which hits, releases ball plate, limit switch is produced a switching signal first, Central control module starts timing, releases the rotation to the left of ball plate and raises, the metal ball positioned at left side does level throw motion, positioned at right side Metal ball do the movement of falling object；

4. pressure sensor is divided into two, respectively positioned at the pick-up point of level throw motion and the pick-up point of freely falling body, two Another signal is produced after metal ball impact pressure sensor, central control module stops timing, and display module, which is shown, to be made The data such as computing formula, result of calculation, the data such as height of the metal ball away from ground, the quality of metal ball can be by keyboard mould The advance typing of block.

In the utility model, bending card frame is fixed on the edge of desk by clamping screw, without with it is hand steered live, and Guide pillar plays a part of guiding, and four adjustment bolts of guide pillar side are used for the level for adjusting substrate, when ball plate is released in weight shock, Ball plate rotation is released, limit switch is discharged and exports a signal, the signal, which is transported to after central control module, starts timing, two Individual metal ball does level throw motion and the movement of falling object, after the two strikes the pressure sensor that ground contraposition is set, produces Signal be transported to central control module, stop timing, the quality of metal ball, the height away from ground are known variables, then coordinated Run duration can calculate the data such as speed, and these data that are known and calculating are shown on display module, very Intuitively, while can show for information such as the formula of calculating, teaching efficiency is improved.
