Abstract
The invention discloses a kind of magazine bullet counter, which belongs to both mechanically and electrically technical field.The magazine bullet counter can make shooter know the bullet number in magazine in time, accomplish to know what's what, and can be adjusted at any time shot residues or replace full magazine.The magazine bullet counter is when bullet number difference in magazine is utilized, this different feature of the elastic force of magazine spring, piezoelectric transducer has been installed additional under magazine snap-gauge, when bullet number difference in magazine, the elastic force that magazine spring pushes magazine snap-gauge changes, magazine snap-gauge is to the pressure of piezoelectric transducer cantilever beam also with generation variation, so as to cause the voltage change of piezoelectric transducer, the voltage is amplified by amplifying circuit, analog-to-digital conversion is carried out using digital-to-analogue converter, finally handled by single-chip microcontroller, output signal is input to LED display by winding displacement, the real-time number of bullet in magazine can be shown when on LED display.As long as the real-time number of bullet in magazine is shown on LED display at once, usually closes power switch in use, pressing power switch button.
Description
Technical field
The present invention relates to a kind of elastic force using magazine spring in magazine, and piezoelectric transducer to be made to generate voltage change, then by voltage
Signal input amplifying circuit, A/D converter and single-chip microcontroller, finally show the bullet of bullet number in magazine on LED display
Casket bullet counter.Technical field of the present invention is both mechanically and electrically technical field.
Background technique
Currently, domestic and countries in the world firearms magazines are all not provided with magazine bullet counting device, shooter was being shot
Do not know also how many hair bullet, by gunlock hole capital after selling all securities on-hook, is at this moment penetrated only after bullet has all been shot in magazine in journey
Hand is just known in magazine without bullet.In order to solve this problem some countries, have developed translucent magazine, this magazine is adopted
With polymer material, the bullet in magazine indistinctly be can see, but there are Railway Projects for this half well-illuminated magazine, first is that not straight
It seeing, shooter will remove several bullets through translucent magazine, and it is cumbersome and easily miscount, it is just more bad especially in hot battle
Operation；Second is that the intensity of translucent magazine material is inadequate, it is easily broken after being collided with；Third is that the production cost of translucent magazine
It is higher, therefore translucent magazine is not also used widely so far.The present invention provides one kind to install counting additional on former magazine
The magazine bullet counter of device, the counter do not influence the intensity of former magazine and the reliability of ammunition feed, using LED display letter
Single bullet number intuitively shown in magazine facilitates shooter to adjust shot residues in time or replace full magazine, to have
Effect improves combat effectiveness of the troops.Apparatus of the present invention are practical and cost is not high, can in high volume equip our troops, army with higher
Thing application value.
Summary of the invention
The present invention provides a kind of magazine bullet counter, the magazine bullet counter is different using bullet number in magazine
When, to the pressure of magazine spring also this different feature, piezoelectric transducer has been installed additional under magazine snap-gauge, when bullet number in magazine
When variation, magazine snap-gauge to the pressure of piezoelectric transducer also with generating variation, so as to cause the voltage change of piezoelectric transducer,
The voltage is amplified and analog-to-digital conversion, is then handled by single-chip microcontroller, so that it may show magazine on LED display at any time
The number of interior bullet makes shooter accomplish to know what's what to the bullet number in magazine, carries out tactics adjustment in time or replacement is full
Magazine.
Detailed description of the invention
Attached drawing 1 is overall structure schematic diagram of the invention.
1. support body in figure, 2. magazine bodies, 3.LED display screen, 4. power switches, 5. magazine springs, 6. display screen winding displacements,
7. magazine snap-gauge, 8. piezoelectric transducers, 9. cantilever beams, 10. circuit boards, 11. button cells, 12. single-chip microcontrollers, 13. magazine lids.
Specific embodiment
Piezoelectric transducer 8 is located at below magazine snap-gauge 7, magazine snap-gauge 7 is in bullet mounted in bottom in magazine body 2 in the figure
It can move up and down in body, toward the built-in bullet of magazine body 2, bullet pressure support body 1 is moved down, and support body 1 compresses magazine spring 5, support
Spring 5 pushes magazine snap-gauge 7, and the lower process of magazine snap-gauge 7 pushes the cantilever beam 9 of piezoelectric transducer 8, has 4 to answer on cantilever beam 9
Power transformation resistance just causes the variation of voltage, piezoelectric transducer 8 is below circuit board 10, on circuit board when cantilever beam generates displacement
There is button cell 11 for whole system power supply, single-chip microcontroller 12 handles voltage signal, and signal is sent to LED by winding displacement 6
Display screen 3, LED display 3 aperture and are fixed on magazine body 2, and the reality in magazine body 2 is shown on LED display 3
When bullet number.Magazine lid 13 is fastened on the bottom of magazine body 2, and power switch 4 controls the switch of entire circuit, when needs are checked
In magazine when bullet number, then 4 are turned on the power switch, usually then turns off the power switch 4.
Claims (6)
