Description

Technical Field

[0001] This utility model relates to the field of command issuing devices, and in particular to a rotary continuous firing command device with alarm function or used in competitive games. Background Technology

[0002] With the continuous development of my country's sports industry, the market demand for various types of starting devices is increasing. As is well known, starting devices are mainly used in outdoor sports such as track and field, swimming, and cycling, as well as for starting commands. Currently, starting devices include electronic starting devices and mechanical starting devices.

[0003] For example, in the Chinese patent CN2909152Y, "Industrial Plastic Support Anti-Modification Dual-Shot Starter," the starter is designed to be made almost entirely of industrial plastic, preventing modification. However, it can only have one main and one auxiliary magazine side-by-side and cannot fire continuously, limiting its use. The rotary starter with patent number 200920151428.0 is a mechanical multi-shot starter, but because the magazine openings of its rotary magazine are arranged radially, vibrations can cause the starting cartridges to fall out of the magazine openings during use. Furthermore, the rotary magazine is driven by a ratchet, which can easily misalign with the firing mechanism, leading to firing failure. Summary of the Invention

[0004] This utility model discloses a rotary continuous firing starter to solve any of the above-mentioned and other potential problems of the prior art.

[0005] To achieve the above objectives, the technical solution of this utility model is: a rotary automatic firing starter, comprising: a housing, a rotary magazine, a trigger, a hammer, and a drive assembly. The housing includes a rotary magazine for loading starting rounds, a hammer for firing starting rounds, a trigger for controlling the hammer, and a drive assembly for driving the rotary magazine to rotate. The housing includes a left housing and a right housing. The rotary magazine is disposed at the front end of the left housing and the right housing via a rotary shaft. A fan-shaped limiting flange for preventing starting rounds from falling out is provided on the edge of the right housing. The fan-shaped limiting flange has a loading port.

[0006] Furthermore, the drive assembly includes a ratchet, a ratchet lever, a positioning groove, and a positioning protrusion;

[0007] The rotary magazine has multiple magazine holes arranged radially to hold starting rounds. Positioning grooves are located on the rotary magazine between the magazine holes. A ratchet is fixed at the center of the rotary magazine. The ratchet has the same number of ratchet teeth as the magazine holes. The positioning protrusion is located on the trigger. One end of the ratchet lever is pivotally connected to the positioning protrusion, and the other end engages with the ratchet teeth.

[0008] Furthermore, the rotary automatic trigger also includes a return spring, which is disposed between the hammer and the connecting rod.

[0009] Furthermore, the rotary automatic trigger also includes a firing exhaust port, which is disposed on the right housing.

[0010] Furthermore, the housing, rotary magazine, trigger, hammer, and drive assembly are all made of aluminum alloy.

[0011] The beneficial effects of this utility model are: by adopting the above technical solution, this utility model not only eliminates the possibility of modification, but also achieves continuous firing effect, and prevents the starting bullet from falling out due to vibration, thus preventing firing failure, making it more convenient to use.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0018] like Figures 1-3As shown, this utility model discloses a rotary automatic firing starter, which includes: a housing, a rotary magazine 4, a trigger 3, a hammer 5, and a drive assembly. The housing has a rotary magazine 4 for loading the starting cartridge, a hammer 5 for firing the starting cartridge, a trigger 3 for controlling the hammer, and a drive assembly for driving the rotary magazine to rotate. The housing includes a left housing 1 and a right housing 2. The rotary magazine 4 is disposed at the front end of the left housing 1 and the right housing 2 via a rotary shaft. The edge of the right housing 2 is provided with a fan-shaped limiting flange 7 for preventing the starting cartridge from falling out. The fan-shaped limiting flange 7 is provided with a loading hole 8.

[0019] The drive assembly includes a ratchet 15, a ratchet lever 14, a positioning groove 9, and a positioning protrusion 12;

[0020] The rotary magazine 4 has multiple magazine holes 11 arranged radially to hold starting rounds. Positioning grooves 9 are arranged on the rotary magazine 4 between the magazine holes 11. The ratchet 15 is fixed at the center of the rotary magazine 4. The ratchet 15 has the same number of ratchet teeth 13 as the magazine holes 11. The positioning protrusion 12 is arranged on the trigger 3. One end of the ratchet lever 14 is pivotally connected to the positioning protrusion 12, and the other end engages with the ratchet teeth 15.

[0021] The rotary type continuous firing starter also includes a return spring 17, which is disposed between the hammer and the connecting rod.

[0022] The rotary automatic starter also includes a firing vent, which is disposed on the left housing.

[0023] The housing, rotary magazine 4, trigger 3, hammer 5, and drive assembly are all made of aluminum alloy.

[0024] The hammer 4 is pivotally connected to the housing via a hammer shaft 19. The lower end of the hammer 4 abuts against a guide rod 20, the lower end of which is positioned at the handle location on the housing. A return spring 21 passes through the guide rod 20 to provide the force for the hammer 4 to strike the trigger cartridge. The trigger 3 is mounted on a trigger shaft 32, which is fixedly connected to the housing, allowing the trigger 3 to rotate relative to the trigger shaft 32. The trigger 3 has a pry end 33 that can move up and down near the hammer 2. A connecting rod 16 is also pivotally connected to the hammer 4.

[0025] In use, the starting rounds are first inserted into the magazine holes 11 of the rotary magazine 4 through the loading holes 8. The fan-shaped limiting flange 7 on the left housing 1 covers half of the magazine hole 8 to prevent the starting rounds from falling out of the magazine hole 11 due to vibration. When firing, the finger pulls the trigger 3, and the ratchet rod connected to the trigger 3 pushes the ratchet 15 to rotate by a ratchet tooth 13. At the same time, the positioning protrusion on the trigger 3 and the positioning groove between the magazine hole 8 cooperate to ensure that the magazine hole 8 is in the firing position. The prying end 33 of the trigger 3 pries, and the swing end 161 of the connecting rod 16 slides away from the prying end 33, breaking the static balance. The hammer 4 is forcefully struck out under the action of the return spring 23 to complete the firing. The smoke generated by the starting round during firing is discharged from the firing exhaust port 6. After completion, the hammer 2 returns to the ready position under the action of the return spring, waiting for the next firing.
