DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-10 The present invention is further described with Examples 1-3.

[0027] Example 1: Figure 1As shown, a handheld transmitter for military police and firefighting includes a gun body, a switch unit and a launch unit. The gun body is connected to a holster 25, and the holster 25 is used to prevent accidental touch by the user. The gun body includes a fixedly connected gun handle 1 and a gun barrel 2. The switch unit and the launch unit are both installed in the gun body. The launch unit includes a sleeve 3, a launch assembly 4 and a locking paddle 6. The sleeve 3 is detachably mounted in the gun barrel 2. The sleeve 3 is provided with a radial locking boss 15. The locking boss 15 and the locking groove provided at the bottom of the gun barrel 2 form a locking fit, which is used to limit the circumferential rotational freedom of the sleeve 3. The firing assembly 4 is movably sleeved in the sleeve 3, and includes a firing piston 41 and a firing member 42. The inner end of the firing piston 41 is provided with a locking end 9, and the outer end of the firing piston 41 is provided with a radially protruding annular outer flange 8. The annular outer flange 8 and the inner end of the firing member 42 form abutment fit. The firing member 42 is a tear gas unit or a window-breaking pointed rod.

[0028] like Figure 4 As shown, an annular inner flange 10 is provided on one side of the sleeve 3 near the locking end 9, and a high-pressure spring 5 for sleeve-connecting the launch assembly 4 is installed between the annular outer flange 8 and the annular inner flange 10, and the high-pressure spring 5 is used to apply an elastic force to the launch assembly 4 to launch outward. An annular groove 11 adapted to the locking paddle 6 is provided in the middle of the locking end 9, and the locking paddle 6 forms a limiting abutment with the end of the sleeve 3. The locking paddle 6 is an arc-shaped sheet structure, and the upper end of the locking paddle 6 is hinged to the end of the sleeve 3 by a first pivot, and the locking paddle 6 is used to limit the axial displacement of the launch assembly 4. Under normal conditions, the middle part of the locking paddle 6 is locked and embedded in the annular groove 11. When the switch unit toggles the locking paddle 6, the locking paddle 6 is turned outward relative to the first pivot and disengaged from the annular groove 11, and the launch assembly 4 is launched outward under the elastic force of the high-pressure spring 5.

[0029] like Figure 4 and Figure 6As shown, the lower part of the locking paddle 6 passes through the sleeve 3 and is exposed to the outside. The switch unit includes a battery 12, a drive switch and a drive motor 13 connected in sequence. The drive switch is used to control the start and stop of the drive motor 13. The drive motor 13 is connected to a cam 14 in transmission. The cam 14 is adapted to the lower part of the locking paddle 6. When the drive motor 13 controls the cam 14 to rotate, the cam 14 presses against the locking paddle 6, so that the locking paddle 6 is separated from the annular slot 11. The existing handheld tear gas sprayer equipped by the police is powered by gas. Due to the low air pressure, the initial spray velocity is only about 3 meters per second, and the spray distance does not exceed five meters. When it is necessary to spray the gas on the face of a specific person being enforced, due to the slow shooting speed and the short spray distance, it is easy for the person being sprayed to dodge and miss the face and head, which greatly affects the law enforcement effect, and cannot quickly and effectively control the criminal suspect! Therefore, the initial velocity of the tear gas sprayed by the single police equipment to be issued by the public security department is mandatory to be 90 to 180 meters per second. According to the requirements of the single police tear gas spraying equipment to be promulgated, our company adopts high pressure spring 5 as the power. The present invention adopts a special fastener that can instantly withstand a large pressure, that is, the locking paddle 6, which is disengaged when the driving motor 13 and the cam 14 are started.

The reset elastic member 18 is used to apply an elastic force to separate the static contact 16 and the moving contact 17. When the user pulls the arc-shaped trigger 19, the moving contact 17 overcomes the elastic force of the reset elastic member 18 and connects the static contact 16, and the drive motor 13 drives the cam 14 to move the locking paddle 6, so that the locking paddle 6 is separated from the annular groove 11. The lower part of the gun barrel 2 is provided with a main power switch 20, a laser sight 21 and a voltage display 22. The main power switch 20 is connected to the battery 12, the drive switch, the laser sight 21 and the voltage display 22 respectively. The main power switch 20 is used to control the start and stop of the connection between the battery 12 and other components. The laser sight 21 is arranged at the lower part of the gun barrel 2 away from the gun handle 1, and the voltage display 22 is arranged on the side surface of the lower part of the gun barrel 2. When the main power switch 20 is started, the battery 12 supplies power to the drive switch, the laser sight 21 and the voltage display 22. At this time, the drive switch can start to control the drive motor 13, the laser sight 21 emits the corresponding aiming laser, and the voltage display 22 displays the existing battery 12 voltage to prevent the battery 12 from being insufficient.

[0031] like Figure 3 As shown, the gun barrel 2 includes an upper tube cover 23 and a lower tube body 24, one side of the upper tube cover 23 is hinged with the lower tube body 24, and the other side of the upper tube cover 23 forms a snap fit with the lower tube body 24 through an elastic snap member 37, and a firing chamber for installing a firing unit is provided between the upper tube cover 23 and the lower tube body 24. When the upper tube cover 23 is flipped open relative to the lower tube body 24, the firing chamber is opened to facilitate the user to directly install the firing unit. The user can flip up the upper tube cover 23 to remove the fired firing unit, replace the new firing unit and cover it, and the snap member will automatically close the upper tube cover 23 and the lower tube body 24, so that the firing can be done immediately, which is convenient and quick.

[0032] like Figure 4 As shown, the end of the sleeve 3 near the launcher 42 is threadedly connected with a locking head 7, the locking head 7 is made of elastic rubber material, the locking head 7 is movably sleeved with the launcher 42, and the inner end surface of the locking head 7 forms a limiting fit with the annular outer flange 8 of the launch piston 41. The locking head 7 can generate static friction force on the launcher 42 to prevent the launcher 42 from accidentally falling off, and can also be used to limit the stroke of the launch piston 41 to prevent the launch piston 41 from falling off. Figure 5As shown, the launcher 42 is a window-breaking pointed rod, and a plurality of elastic locking components are arranged in the inner circumference of the locking head 7, and the elastic locking components include a pressure screw 34, a compression spring 35 and a round steel ball 36 connected in sequence, and the thread of the pressure screw 34 is radially adapted to the radial threaded hole provided in the locking head 7, and the inner end of the pressure screw 34 is connected to the compression spring 35, and the round steel ball 36 is subjected to the elastic force of the compression spring 35 and abuts against the surface of the window-breaking pointed rod, and the round steel ball 36 has a limiting effect on the window-breaking pointed rod. The user can control the pressure locking of the round steel ball 36 on the window-breaking pointed rod by adjusting and rotating the pressure screw 34.

[0033] Example 2: Figure 8 As shown, a handheld transmitter for military police and firefighting includes a gun body, a switch unit and a launch unit. The gun body is externally connected to a holster 25, and the holster 25 is used to prevent accidental touch by the user. The gun body includes a gun handle 1 and a gun barrel 2 that are fixedly connected. The switch unit and the firing unit are both installed in the gun body. The firing unit includes a sleeve 3, a firing assembly 4 and a locking paddle 6. The sleeve 3 is detachably mounted in the gun barrel 2. The sleeve 3 is provided with a radial locking boss 15. The locking boss 15 and the locking groove provided at the bottom of the gun barrel 2 form a locking fit to limit the circumferential rotational freedom of the sleeve 3. The firing assembly 4 is movably sleeved in the sleeve 3. The firing assembly 4 includes a firing piston 41 and a firing member 42. The inner end of the firing piston 41 is provided with a locking end 9. The outer end of the firing piston 41 is provided with a radially protruding annular outer flange 8. The annular outer flange 8 forms abutment fit with the inner end of the firing member 42. The firing member 42 is a tear gas unit or a window-breaking pointed rod.

[0034] An annular inner flange 10 is provided on one side of the sleeve 3 near the locking end 9, and a high-pressure spring 5 for sleeve-connecting the launching component 4 is installed between the annular outer flange 8 and the annular inner flange 10 to limit the position. The high-pressure spring 5 is used to apply an elastic force to the launching component 4 to launch outward.

[0035] An annular groove 11 adapted to the locking paddle 6 is provided in the middle of the locking end 9. The locking paddle 6 and the end of the sleeve 3 form a limiting abutment. The locking paddle 6 is an arc-shaped sheet structure. The upper end of the locking paddle 6 is hinged to the end of the sleeve 3 by a first pivot. The locking paddle 6 is used to limit the axial displacement of the launching assembly 4.

[0036] Under normal conditions, the middle part of the locking paddle 6 is engaged in the annular slot 11. When the switch unit moves the locking paddle 6, the locking paddle 6 is turned outward relative to the first pivot and disengaged from the annular slot 11. The launching assembly 4 is launched outward under the elastic force of the high-pressure spring 5.

[0037] The lower part of the locking paddle 6 passes through the sleeve 3 and is exposed to the outside. The switch unit includes a battery 12, a drive switch and a drive motor 13 connected in sequence. The drive switch is used to control the start and stop of the drive motor 13. The drive motor 13 is connected to a cam 14. The cam 14 is adapted to the lower part of the locking paddle 6. When the drive motor 13 controls the cam 14 to rotate, the cam 14 presses against the locking paddle 6, so that the locking paddle 6 is separated from the annular slot 11. The existing handheld tear gas sprayer equipped by the police is powered by gas. Due to the low air pressure, the initial spray velocity is only about 3 meters per second, and the spray distance does not exceed five meters. When it is necessary to spray the gas on the face of a specific person being enforced, due to the slow shooting speed and the short spray distance, it is easy for the person being sprayed to dodge and miss the face and head, which greatly affects the law enforcement effect, and cannot quickly and effectively control the criminal suspect! Therefore, the initial velocity of the tear gas sprayed by the single police equipment to be issued by the public security department is mandatory to be 90 to 180 meters per second. According to the requirements of the single police tear gas spraying equipment to be announced, our company uses high pressure spring 5 as the power. The present invention adopts a special fastener that can withstand a large pressure instantly, that is, the locking paddle 6. When the driving motor 13 and the cam 14 are started, the locking paddle 6 is disengaged. When the high pressure spring 5 is released instantly, a strong pressure is generated to cause the outer plug 31 equipped with a silicone sealing ring to quickly spray the tear gas liquid pre-installed in the front part of the tube cavity out of the launch hole. The initial velocity can reach 118 meters per second, which fully meets the requirements of the single police tear gas spraying equipment with an initial velocity of 1.90-180 meters per second! The gun handle 1 is provided with an installation chamber for accommodating a battery 12 and a drive motor 13. The battery 12 is arranged below the drive motor 13.

The lower end of the moving contact 17 extends outwardly and is provided with an arc trigger 19. The reset elastic member 18 is used to apply an elastic force to separate the static contact 16 and the moving contact 17. When the user pulls the arc trigger 19, the moving contact 17 overcomes the elastic force of the reset elastic member 18 and connects the static contact 16. The drive motor 13 drives the cam 14 to move the locking paddle 6, so that the locking paddle 6 is separated from the annular groove 11. The lower part of the gun barrel 2 is provided with a main power switch 20, a laser sight 21 and a voltage display 22. The main power switch 20 is connected to the battery 12, the drive switch, the laser sight 21 and the voltage display 22 respectively. The main power switch 20 is used to control the start and stop of the connection between the battery 12 and other components. The laser sight 21 is arranged at the lower part of the gun barrel 2 away from the gun handle 1, and the voltage display 22 is arranged on the side surface of the lower part of the gun barrel 2. When the main power switch 20 is started, the battery 12 supplies power to the drive switch, the laser sight 21 and the voltage display 22. At this time, the drive switch can start to control the drive motor 13, the laser sight 21 emits the corresponding aiming laser, and the voltage display 22 displays the existing battery 12 voltage to prevent the battery 12 from being insufficient.

[0038] The gun barrel 2 includes an upper tube cover 23 and a lower tube body 24. One side of the upper tube cover 23 is hinged with the lower tube body 24, and the other side of the upper tube cover 23 forms a detachable snap fit with the lower tube body 24. A firing chamber for installing a firing unit is provided between the upper tube cover 23 and the lower tube body 24.
