DETAILED DESCRIPTION
[0022] The application will be further described below with reference to the specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative changes belong to the protection scope of the application.
[0023] As shown in the figure, a device for preventing the second impact of a grenade bag 100, comprising a support, further comprising: Figure 1 A stop rod is arranged on the support.
[0024] A driving mechanism is arranged on the support for driving the stop rod 1 to move up and down on the support.
[0025] A detection mechanism 3 is arranged on the support for detecting the position of the grenade bag 100 and electrically connected with the driving mechanism.
[0026] As shown in the figure, during the test, the device is arranged at the front end of the grenade bag 100 impact test device. The stop rod 1 is arranged at a position about 100 mm below the landing point of the grenade bag 100 in the initial position. The position of the grenade bag 100 is detected by the detection mechanism 3. When the grenade bag 100 is impacted for the first time, a signal is transmitted to the driving mechanism. During the rebounding process of the grenade bag 100, the driving mechanism controls the stop rod 1 to move to the position between the grenade bag 100 and the test glass, thereby avoiding the second impact of the grenade bag 100 on the glass.
[0027] Figure 3 In some embodiments, in order to facilitate the installation and the up and down movement of the stop rod 1, the support comprises a crossbar 12 and two oppositely arranged columns 11. The two ends of the crossbar 12 are respectively fixed to the top of the two columns 11. The driving mechanism is arranged on the columns 11.
[0028] In some embodiments, in order to facilitate the installation and the up and down movement of the stop rod 1, the support comprises a crossbar 12 and two oppositely arranged columns 11. The two ends of the crossbar 12 are respectively fixed to the top of the two columns 11. The driving mechanism is arranged on the columns 11.
[0029] In some embodiments, in order to better control the movement of the stop rod 1, the driving mechanism comprises a driving motor 21, a control cabinet 22, a synchronous wheel 23 and a synchronous belt 24, the upper and lower ends of the two upright columns 11 are provided with the synchronous wheels 23, the synchronous wheels 23 are in driving connection with the driving motor 21, the synchronous belt 24 is installed on the synchronous wheels 23, the two ends of the stop rod 1 are fixedly provided on the synchronous belt 24, the control cabinet 22 is in electrical signal connection with the detection mechanism 3, and the control cabinet 22 is used for controlling the operation of the driving motor 21. The driving motor 21 drives the synchronous wheels 23 and the synchronous belt 24 to rotate, so as to drive the rising and falling of the stop rod 1.
[0030] In some embodiments, in order to better control the up and down movement of the stop rod 1, a guide rod 13 is further fixed on one side of the upright column 11, and the two ends of the stop rod 1 are slidingly provided on the guide rod 13. The guide rod 13 can avoid the deflection of the stop rod 1. Specifically, guide holes can be arranged at the two ends of the upright column 11, and the guide rod 13 is slidingly connected with the guide holes.
[0031] In order to effectively control the running height of the stop rod 1 and prevent the height from being too high when moving upward, so as to prevent the stop rod 1 from not playing a stopping role, in some embodiments, a limit switch 25 is arranged on the upright column 11, and the limit switch 25 is used for controlling the rising height of the stop rod 1. When the stop rod 1 runs to contact the limit switch 25, the limit switch 25 is pressed down, the limit switch 25 controls the driving motor 21 to stop running, and the limit switch 25 can be arranged at the height of the impact point of the canister 100.
[0032] In order to improve the stability of the device, in some embodiments, a fixed column 14 is further arranged at the bottom of the upright column 11, the fixed column 14 is perpendicular to the upright column 11, and an inclined support 15 is further arranged between the fixed column 14 and the upright column 11, and the fixed column 14, the upright column 11 and the inclined support 15 form a triangular stable structure. The triangular stable structure can improve the stability of the entire device. Of course, the upright column 11 in the above embodiments can be directly connected and fixed with the canister 100 impact testing device to simplify the structure.
[0033] Specifically, the detection mechanism 3 is a grating mechanism, an installation plate is arranged on the upright column 11, a transmitting end of the grating mechanism is installed on one upright column 11 through the installation plate, a receiving end of the grating is installed on the other upright column 11 through the installation plate, the receiving end and the transmitting end are oppositely arranged, and the height of the grating mechanism is consistent with the height of the impact point of the canister 100.
[0034] As shown in Figure 3 It is shown that the application also provides a canister 100 impact testing device comprising the device for preventing the secondary impact of the canister 100.
[0035] In some embodiments, asFigure 2 As shown, the shotbag 100 impact testing device includes a mounting frame 41, a shotbag 100 release mechanism, and an adjustment mechanism 44. The shotbag 100 release mechanism includes a fixed arm 42, a swing arm 43, and a shotbag 100. The fixed arm 42 is fixedly mounted above the mounting frame 41. One end of the swing arm 43 is hinged to the fixed arm 42. The adjustment mechanism 44 can adjust the angle between the fixed arm 42 and the swing arm 43. The other end is provided with a control mechanism 45 for fixing or releasing the shotbag 100. The shotbag 100 is connected to the swing arm 43 by a rope 46.
[0036] Specifically, the fixed arm 42 can be horizontally fixed above the mounting frame 41. The adjusting mechanism 44 can also be a pull rope, allowing adjustment of the angle between the fixed arm 42 and the swing arm 43 by adjusting the length of the pull rope. The control mechanism 45 can also be a pull rope; before testing, the shotgun pouch 100 is fixed to the end of the swing arm 43 using the pull rope, and the pull rope is cut upon release. This application is not limited to these methods.
[0037] During testing, the tempered glass to be tested is installed in the mounting frame 41. The shotgun bag 100 is fixed to one end of the swing arm 43 via the control mechanism 45. The angle between the swing arm 43 and the fixed arm 42 is adjusted according to the testing requirements, i.e., the height of the end of the swing arm 43 is adjusted, which is also the height of the shotgun bag 100. The control mechanism 45 releases the shotgun bag 100. Under the constraint of gravity and the rope 46, the shotgun bag 100 swings and impacts the tempered glass. When the shotgun bag 100 impacts the tempered glass for the first time, the detection mechanism 3 detects this state and transmits a signal to the control cabinet 22. At the same time as the shotgun bag 100 rebounds, the control cabinet 22 controls the drive motor 21 to start. The synchronous belt 24 drives the stop bar 1 to rise to the position between the shotgun bag 100 and the tempered glass. When the shotgun bag 100 falls again, it is stopped by the stop bar 1 and will not impact the tempered glass again. The detection mechanism 3 can use the above-mentioned grating mechanism, and the rising height of the stop bar 1 can be controlled by the limit switch 25. Of course, if the tempered glass is broken by the impact of the shotgun bag 100, then the tempered glass does not meet the standard, and the stop bar 1 cannot move between the shotgun bag 100 and the tempered glass, but this does not affect the accuracy of the test results.
[0038] like Figure 3 As shown, in order to facilitate the assembly of the device for preventing secondary impact of the shotbag 100 with the testing device, in some embodiments, the bracket of the device for preventing secondary impact of the shotbag 100 includes two opposing columns 11, and the distance between the two columns 11 is greater than the width of the mounting frame 41.
[0039] Since the width between the columns 11 is greater than the width of the mounting frame 41, the device for preventing the second impact of the shot bag 100 is directly attached to the outer side of the test device during installation, which does not affect the test. When the device for preventing the second impact of the shot bag 100 has the fixed column 14 and the diagonal brace 15, the fixed column 14 and the diagonal brace 15 are also located on the outer side of the test device, and a connecting structure such as a connecting plate 16 can be provided between the fixed column 14 and the diagonal brace 15 and the test device to form a stable whole.
[0040] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited to this. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present application.
