Abstract
The invention discloses a thruster with a fixed thrust value. The thruster comprises a barrel body, a pushing rod and a base, wherein the barrel body and the base are connected by a thread; a pushing rod baffle plate is arranged on the middle part of the pushing rod; a main spring is arranged between the pushing rod baffle plate and the base; a buffer spring is arranged between the pushing rod baffle plate and the front end of the barrel body; a guide rod parallel to the pushing rod is arranged on the front part of the pushing rod; a plurality of clamping slots are formed in the guide rod; a pressure plate which is matched with the clamping slots in the guide rod is arranged on the front part of the barrel body; the upper and lower parts on the tail end of the pressure plate are respectively provided with a button and a pressure plate spring; and a button hole corresponding to the button is formed in the barrel body. The thruster has a simple structure, convenience in use and low cost, and ensures the stability of the fixed thrust value generated by the thruster; simultaneously, the fixed thrust value generated by the thruster can be conveniently changed by changing the positions of the clamping slots in the spring or the guide rod, so that the application range is further expanded.
Description
Technical field
The present invention relates to a kind of thruster, relate in particular to a kind of thrust magnitude thruster of deciding.
Background technique
At present, in current experiments equipment, the experimental facilities that fixed energies thrust is provided that generally uses is for impacting gas big gun (adding the ability big gun), and this kind equipment realizes providing the thrust of certain energy value through pressurized air.
And in actual use, similar this kind can provide the fixedly thruster of thrust, all is the compressed air to do work that utilizes cylinder, reaches fixing thrust magnitude, the entire equipment complex structure, and volume is big, cost is high, operation needs the professional workforce, and the device maintenance expense is expensive.All unfavorable factors make it be difficult to be applied widely, and often do not need so accurate experimental facilities for ordinary test checking project, and test place, environment also might not be fixed, and the Applicable scope of the said equipment further is limited.
Summary of the invention
The invention discloses a kind of thrust magnitude thruster of deciding, to solve the present shortage problem of deciding the thrust magnitude thruster simple in structure, with low cost.
The objective of the invention is to realize through following technological scheme:
A kind ofly decide the thrust magnitude thruster, comprise cylindrical shell, push rod and base, cylindrical shell is connected with base by thread; Said push rod middle part is provided with the push rod baffle plate, is provided with main spring between push rod baffle plate and the base, is provided with damping spring between push rod baffle plate and the barrel front end, and the push rod front portion is provided with the guide rod parallel with push rod, and guide rod is provided with some draw-in grooves; Said cylindrical shell front portion be provided with guide rod on the pressing plate that matches of draw-in groove, pressing plate tail end upper and lower is respectively equipped with button and rag iron spring; Position corresponding with button on the said cylindrical shell is provided with button hole.
Further, said base top is provided with the base sleeve that matches with push rod.
Preferably, said guide rod is a square cross.
Beneficial effect of the present invention is: simple in structure; Easy to use; With low cost, and guaranteed the stability of deciding thrust magnitude that thruster produced, simultaneously can be through change to draw-in groove position on spring or the guide rod; Change the size of deciding thrust magnitude that thruster produces easily, further enlarged application area of the present invention.
Description of drawings
According to accompanying drawing the present invention is done further explain below.
Fig. 1 is a kind of structural representation of deciding the thrust magnitude thruster of embodiments of the invention;
Fig. 2 is a kind of structural representation sectional view of deciding the thrust magnitude thruster of embodiments of the invention.
Among the figure:
1, cylindrical shell; 2, push rod; 21, push rod baffle plate; 3, guide rod; 4, base; 41, base sleeve; 5, main spring; 6, damping spring; 7, button; 8, pressing plate; 9, rag iron spring.
Embodiment
Shown in Fig. 1-2, the described a kind of thrust magnitude thruster of deciding of the embodiment of the invention comprises cylindrical shell 1, push rod 2 and base 4, and cylindrical shell 1 and base 4 are through being threaded.Said push rod 2 middle parts are provided with push rod baffle plate 21, are provided with main spring 5 between push rod baffle plate 21 and the base 4, and main spring 5 plays the effect of deciding thrust that thruster is provided, when changing different main springs 5, and can be so that the thrust of deciding that thruster produces changes thereupon.Be provided with damping spring 6 between push rod baffle plate 21 and cylindrical shell 1 front end, main spring 5 promotion push rods 2 actings that are arranged so that of damping spring 6 play buffer function afterwards between push rod 2 and staving 1, avoid push rod 2 directly to bump against on the staving 1.
Said cylindrical shell 1 front portion be provided with guide rod 3 on the pressing plate 8 that matches of draw-in groove, pressing plate 8 tail end upper and lowers are respectively equipped with button 7 and rag iron spring 9; Be provided with button hole with button 7 corresponding positions on the said cylindrical shell 1.Said base top is provided with the base sleeve 41 that matches with push rod 2, makes the position of push rod 2 obtain further qualification, has guaranteed that push rod 2 is unlikely in cylindrical shell 1, to slide.Said guide rod 3 selects for use square cross then to make the leading role between guide rod 3 and the cylindrical shell 1 more outstanding, has further guaranteed to decide the degree of accuracy of thrust magnitude.
During concrete the use, promote push rod 2 at front end the dead bolt of pressing plate 8 is depressed in the groove that snaps on the guide rod 3, when having an effect at the following of rag iron spring 9; Press button 7; Button 7 is pressed the dead bolt of pressing plate 8 through lever principle, thereby push rod 2 is got loose, and main spring 5 promotes push rod 2 and has an effect forward.Because of the decrement of each spring is identical,, thereby realized that thrust fixes so the thrust that each push rod provides is also identical.
Though below only described embodiment example of the present invention, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention is limited appended claims.Those skilled in the art can make numerous variations or modification to these mode of executions under the prerequisite that does not deviate from principle of the present invention and essence, but these changes or modification all fall into protection scope of the present invention.
