Description
Technical field
The utility model is related to education sectors, are specifically related to a kind of teaching experiment candle-fixing device.
Background technology
Teaching experiment either Physical Experiment or chemical experiment, is often required to use candle, during experiment, to the candlelight of candle
Height requires, and then can not be continuing with after causing some candle combustions for a period of time, and the wax that candle combustion flows down
Oil can also make everywhere, very inconvenient.
Utility model content
The technical problems to be solved in the utility model is the defects of overcoming prior art teaching experiment candle inconvenient for use, to carry
For a kind of teaching experiment candle-fixing device.
In order to solve the above technical problems, the utility model provides following technical scheme：A kind of teaching experiment is fixed with candle
Device, including collection device, the collection device is set to cylindrical structure, and the bottom of collection device opens up port, passage port one
Body connecting sucker, the inner concave of the sucker are located in collection device, and transverse slat is pasted in the inner concave external stability of sucker, described
The upper side of transverse slat is vertically arranged riffled tube, and screw rod is installed in riffled tube, and the lower end of the screw rod is located in riffled tube,
The upper end of screw rod is fixedly connected with plectane, and the plectane symmetrically opens up tapped through hole by connecting rod fixed connecting sleeve, described sleeve pipe,
It is located at tapped through hole through bolt, the end of bolt in casing, and the end flexible connection arc plate of bolt.
Further, the upper side circle centre position of the plectane is vertically arranged pilot pin.
Further, the path length of described sleeve pipe is less than the path length of collection device.
Further, the bolt is not stretched out in the range of collection device.
The utility model has an advantageous effect in that compared with prior art：A kind of teaching experiment candle-fixing device,
It is rational in infrastructure, it is easy to use, a candle-fixing device is designed, can be adapted for different model, the candle of length uses, candle
The wax oil flowed down that burns can be stayed in collection device, cleared up convenient for concentrating so that experiment is more convenient, saves worry, and advantageously reduces reality
The consumption of material is tested, improves conventional efficient.
Description of the drawings
Fig. 1 is a kind of teaching experiment candle-fixing device internal structure schematic diagram of the utility model；
Fig. 2 is a kind of teaching experiment candle-fixing device overlooking the structure diagram of the utility model.
Figure label is：1- collection devices；2- suckers；3- transverse slats；4- riffled tubes；5- screw rods；6- plectanes；7- connecting rods；
8- casings；9- bolts；10- arc plates；11- pilot pins.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
It is understood referring to figs. 1 to Fig. 2：A kind of teaching experiment candle-fixing device, it is described to collect dress including collection device 1
It puts 1 and is set to cylindrical structure, the bottom of collection device 1 opens up port, passage port integrally connected sucker 2, the indent of the sucker 2
Face is located in collection device 1, and transverse slat 3 is pasted in the inner concave external stability of sucker 2, and the upper side of the transverse slat 3 is vertically arranged
Riffled tube 4, the interior installation screw rod 5 of riffled tube 4, the lower end of the screw rod 5 are located in riffled tube 4, and the upper end of screw rod 5 is fixed
Plectane 6 is connected, the plectane 6 symmetrically opens up tapped through hole, tapped through hole by 7 fixed connecting sleeve 8 of connecting rod, described sleeve pipe 8
Place is located at through bolt 9, the end of bolt 9 in casing 8, and the end flexible connection arc plate 10 of bolt 9.
The upper side circle centre position of the plectane 6 is vertically arranged pilot pin 11, convenient for candle fixing；The path length of described sleeve pipe 8
Less than the path length of collection device 1, wax is dripped convenient for collecting；The bolt 9 is not stretched out in the range of collection device 1, reduces occupied space.
The principle and advantage of the utility model：During operation, experimental height requirement, revoling tube 8, screw rod 5 screws out
In riffled tube 4, candle bottom is inserted in pilot pin 11 by the height of adjusting sleeve pipe 8, and candle can push while fixed
Plectane 6, riffled tube 4 and screw rod 5 simultaneously decline, and transverse slat 3 uniformly exerts a force to sucker 2, and the air discharge absorption in sucker 2 exists
On experimental bench or inside vessel, the enhancing of the stability of device entirety at this point, if candle is long, generates crooked, rotatable bolt
9, two blocks of arc plates 10 vertically clamp candle, facilitate experiment, and too short candle is directly clamped with arc plate 10, without inserting
Enter pilot pin 11, the wax oil that candle combustion flows down can be stayed in collection device 1, cleared up convenient for concentrating.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
