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, particularly relate to one and determine thrust magnitude thruster.
Background technique
At present, in existing experimental facilities, what generally use provides the experimental facilities of fixed energies thrust for impacting gas big gun (adding energy big gun), and this kind of equipment realizes by pressurized air the thrust providing certain energy value.
And in actual use, this kind similar can provide the thruster of fixing thrust, be all the compressed air to do work utilizing cylinder, reach fixing thrust magnitude, whole device structure is complicated, and volume is large, cost is high, operation needs professional workforce, and 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 Verification Project, and test site, environment also might not be fixed, and the Applicable scope of the said equipment is further limited.
Summary of the invention
The invention discloses one and determine thrust magnitude thruster, lack the structure problem of determining thrust magnitude thruster simple, with low cost at present to solve.
The object of the invention is to be achieved through the following technical solutions:
One determines thrust magnitude thruster, and comprise cylindrical shell, push rod and base, cylindrical shell is connected with base by thread; Be provided with push rod baffle plate in the middle part of described push rod, be provided with main spring between push rod baffle plate and base, be provided with damping spring between push rod baffle plate and barrel front end, push rod front portion is provided with the guide rod parallel with push rod, and guide rod is provided with some draw-in grooves; Described cylindrical shell front portion is provided with the pressing plate matched with the draw-in groove on guide rod, and pressing plate tail end upper and lower is respectively equipped with button and rag iron spring; Position corresponding with button on described cylindrical shell is provided with button hole.
Further, described base top is provided with the base sleeve matched with push rod.
Preferably, described guide rod is square cross.
Beneficial effect of the present invention is: structure is simple, easy to use, with low cost, and ensure that the stability of determining thrust magnitude that thruster produces, simultaneously can by the change to draw-in groove position on spring or guide rod, change the size of determining thrust magnitude that thruster produces easily, expand application area of the present invention further.
Accompanying drawing explanation
With reference to the accompanying drawings the present invention is described in further detail below.
Fig. 1 is a kind of structural representation determining thrust magnitude thruster of embodiments of the invention;
Fig. 2 is a kind of structural representation sectional view determining thrust magnitude thruster of embodiments of the invention.
In 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
As shown in Figure 1-2, the one described in the embodiment of the present invention determines thrust magnitude thruster, comprises cylindrical shell 1, push rod 2 and base 4, and cylindrical shell 1 and base 4 are threaded connection.Be provided with push rod baffle plate 21 in the middle part of described push rod 2, be provided with main spring 5 between push rod baffle plate 21 and base 4, main spring 5 plays the effect determining thrust providing thruster, and when changing different main springs 5, the thrust of determining that thruster can be made to produce changes thereupon.Be provided with damping spring 6 between push rod baffle plate 21 and cylindrical shell 1 front end, damping spring 6 be arranged so that main spring 5 promote push rod 2 do work after between push rod 2 and staving 1, play buffer function, avoid push rod 2 directly to bump against on staving 1.
Push rod 2 front portion is provided with the guide rod 3 parallel with push rod 2, guide rod 3 is provided with some draw-in grooves, on the one hand, guide rod 3 by with the coordinating of cylindrical shell 1, serve the effect of fixing push rod 2, on the other hand, by the adjustment to draw-in groove position on guide rod 3, the compression of push rod 2 pairs of main springs 5 is adjusted, different determines thrust to produce.
Described cylindrical shell 1 front portion is provided with the pressing plate 8 matched with the draw-in groove on guide rod 3, and pressing plate 8 tail end upper and lower is respectively equipped with button 7 and rag iron spring 9; On described cylindrical shell 1, the position corresponding with button 7 is provided with button hole.Described base top is provided with the base sleeve 41 matched with push rod 2, makes the position of push rod 2 obtain further restriction, ensure that push rod 2 is unlikely to slide in cylindrical shell 1.Described guide rod 3 selects square cross then to make the leading role between guide rod 3 and cylindrical shell 1 more outstanding, further ensure that the degree of accuracy determining thrust magnitude.
During concrete use, promote push rod 2 in front end and make the dead bolt of pressing plate 8 snap in the groove on guide rod 3, when having an effect in the lower pressure of rag iron spring 9, button press 7, button 7 is pressed by the dead bolt of lever principle by pressing plate 8, thus push rod 2 is got loose, and main spring 5 promotes push rod 2 and has an effect forward.Because the decrement of each spring is identical, so the thrust that each push rod provides is also identical, thus achieves thrust and fix.
Although above only describes the specific embodiment of the present invention example, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present invention and essence, can make various changes or modifications to these mode of executions, but these change or amendment all falls into protection scope of the present invention.
