Description
Technical field
The utility model belongs to teaching technique with the apparatus field, is specifically related to a kind of novel middle school physical experiment track pulley cribbing.
Background technology
Give lessons in practice long-term; teacher does in experimentation at use support for student; frequent meeting carrys out observation experiment effect with differing heights in same experiment; using common rule to carry out measuring height error when regulating height can be very large; and use jackscrew to be easy to slide fastener for a long time when being fixed on column by hook with jackscrew, inconvenient teacher uses and increases experimental result error.
Summary of the invention
The purpose of this utility model is: in order to solve teacher at use support for student does in experimentation, hook height can be regulated at any time and can be fixed on accurately on applicable height simultaneously, and can firmly hook be fixed on column, can reduce experimental result error and facilitate teacher to use, its technical scheme is as follows:
A kind of novel middle school physical experiment track pulley cribbing, it comprises firm banking 1, vertical columns 2, highly mark 3, sawtooth 4, fixing sliding sleeve 5, fixed hook 6, adjustment turns round 7, driving gear 8, it is characterized in that: on described firm banking 1, top end surface back edge middle is fixedly connected with vertical columns 2, described vertical columns 2 left and right sides top end surface front edge place is provided with and highly marks 3, after described vertical columns 2, top end surface is provided with sawtooth 4, described vertical columns 2 outside surface is fitted with fixing sliding sleeve 5, before described fixing sliding sleeve 5, top end surface middle is fixedly connected with fixed hook 6, the right top end surface middle of described fixing sliding sleeve 5 is fixedly connected with adjustment and turns round 7, top end surface middle, described fixing sliding sleeve 5 inner left and right is fixedly connected with driving gear 8, indentation on described driving gear 8 side surface and described sawtooth 4 indentation cooperatively interact, described driving gear about 8 top end surface circle centre position is respectively fixedly connected with rotating shaft, the described rotating shaft in right side penetrates fixing sliding sleeve 5 and turns round 7 left top end surface circle centre positions with described adjustment and be fixedly connected with, described rotating shaft and described fixing sliding sleeve 5 are mutually permanently connected by bearing, below the concave arc outside surface of described fixed hook 6 front top, point of contact and described fixing sliding sleeve 5 times top end surfaces are in same plane.
The beneficial effects of the utility model are: in order to solve teacher at use support for student does in experimentation, hook height can be regulated at any time and can be fixed on accurately on applicable height simultaneously, and can firmly hook be fixed on column, experimental result error can be reduced and facilitate teacher to use.
accompanying drawing illustrates:
Fig. 1 is one-piece construction schematic diagram of the present utility model.
embodiment:
With reference to a kind of novel middle school physical experiment track pulley cribbing described in Fig. 1, it comprises firm banking 1, vertical columns 2, highly mark 3, sawtooth 4, fixing sliding sleeve 5, fixed hook 6, adjustment turns round 7, driving gear 8, it is characterized in that: on described firm banking 1, top end surface back edge middle is fixedly connected with vertical columns 2, described vertical columns 2 left and right sides top end surface front edge place is provided with and highly marks 3, after described vertical columns 2, top end surface is provided with sawtooth 4, described vertical columns 2 outside surface is fitted with fixing sliding sleeve 5, before described fixing sliding sleeve 5, top end surface middle is fixedly connected with fixed hook 6, the right top end surface middle of described fixing sliding sleeve 5 is fixedly connected with adjustment and turns round 7, top end surface middle, described fixing sliding sleeve 5 inner left and right is fixedly connected with driving gear 8, indentation on described driving gear 8 side surface and described sawtooth 4 indentation cooperatively interact, described driving gear about 8 top end surface circle centre position is respectively fixedly connected with rotating shaft, the described rotating shaft in right side penetrates fixing sliding sleeve 5 and turns round 7 left top end surface circle centre positions with described adjustment and be fixedly connected with, described rotating shaft and described fixing sliding sleeve 5 are mutually permanently connected by bearing, below the concave arc outside surface of described fixed hook 6 front top, point of contact and described fixing sliding sleeve 5 times top end surfaces are in same plane.
During use, first firm banking 1 is placed on the table, then hold and rotate adjustment turn round 7 make driving gear 8 rotate and driving gear 8 move up and down on sawtooth 4, fix sliding sleeve 5 to slide on vertical columns 2 simultaneously, then the height mark 3 observed on vertical columns 2 side surface regulates suitable height, finally will test thing and close on fixed hook 6.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
