Description

Technical Field

[0001] This utility model relates to the technical field of glass-breaking ball launching devices, specifically to a locking mechanism for a pneumatic launcher and a pneumatic launcher. Background Technology

[0002] A glass-breaking device (or glass-breaking equipment) is a specialized remote glass-breaking device used for throwing glass-breaking balls. It is widely used in firefighting and rescue operations. Currently, glass-breaking devices have diverse structures. For example, Chinese patent CN211893653U discloses a pneumatic glass-breaking ball launching mechanism, which can be mounted on a drone. This launching mechanism specifically includes a power chamber, a sealing mechanism, and a locking mechanism. The power chamber and the sealing mechanism are mutually compatible. The sealing mechanism is movably located at one end of the power chamber for sealing and opening the power chamber. The locking mechanism is mutually compatible with the sealing mechanism for locking and unlocking the sealing mechanism. When the locking mechanism locks the sealing mechanism, the power chamber is closed, and the air pressure inside the power chamber can rise to the pressure required to throw the glass-breaking ball. When it is necessary to throw the glass-breaking ball, the locking mechanism unlocks the sealing mechanism. Under the action of the air pressure inside the power chamber, the sealing mechanism moves and releases the high-pressure gas inside the power chamber. The high-pressure gas acts on the glass-breaking ball in the launching channel, thereby launching the glass-breaking ball through air pressure.

[0003] The glass-breaking ball launcher disclosed in Chinese patent CN211893653U is an early-generation product. Its sealing mechanism includes a reset spring for resetting; the locking mechanism comprises a locking element and a trigger rod. The locking element is rotatably mounted on the generator body. The sealing mechanism has a slot that matches the locking element. When one end of the locking element is engaged with the slot, the sealing mechanism is restricted by the locking element. The other end of the locking element is connected to the trigger rod. Through the trigger rod, the locking element can be raised or lowered using leverage, thereby unlocking and locking the sealing mechanism. In actual operation, the reset spring, locking mechanism, and sealing mechanism need to cooperate to continuously achieve processes such as gas storage, activation, resetting, and re-gas storage.

[0004] However, in existing glass-breaking ball launchers, at the moment of unlocking, the high-pressure gas in the gas chamber drives the sealing mechanism to move and automatically release, and the gas pressure in the gas chamber drops instantly. During this process, the reset spring is further compressed, and the elastic potential energy continues to increase. After the gas in the gas chamber is completely released, the reset spring drives the sealing mechanism to move in the opposite direction for automatic reset. In practice, the venting process is very fast, making the reset process also very fast. At this time, the trigger used for transmission usually has not yet started to reset. This difference affects the engagement speed between the locking element and the sealing mechanism, thus affecting the reset efficiency. Especially when the trigger is driven by a motor, the reset efficiency is even lower. In addition, it also affects the stability and reliability of the reset process, and may even cause the locking element to fail to engage with the sealing mechanism, which urgently needs to be solved. Summary of the Invention

[0005] The first aspect of this utility model is to solve the above-mentioned problems by providing a locking mechanism that can cooperate more efficiently with a blocking mechanism. This mechanism not only has higher reset efficiency but also a more stable and reliable reset process. The main concept is as follows:

[0006] A locking mechanism for a pneumatic launcher includes a bracket, a trigger, a locking member, and an elastic member. The trigger is vertically and flexibly constrained to the bracket. The locking member includes a first end and a second end, and has a hinge hole, which is a slotted hole, located between the first and second ends. The first end of the locking member has a locking portion adapted to a sealing mechanism. The bracket has a shaft, and the locking member is fitted onto the shaft through the hinge hole, allowing the locking member to rotate and move relative to the shaft. When the locking member moves towards the trigger, the second end of the locking member can move below the trigger. The elastic member is used to press down the first end of the locking member. The trigger is used to press the second end of the locking member to lift the first end of the locking member. In this design, an elastic element is configured to act on the locking element, providing downward pressure to the first end of the locking element. This ensures a more stable and reliable locking engagement between the locking part and the sealing mechanism, preventing automatic disengagement and accidental triggering. By using a slotted hole in the hinge hole structure, the locking element can not only rotate relative to the shaft to move away from the unlocking sealing mechanism using a lever for triggering, but also move relative to the shaft. This allows control over the power transmission between the locking element and the trigger element by changing the locking element's position. When the pneumatic launcher's air chamber is inflated, the locking element moves towards the trigger element under air pressure, allowing the second end of the locking element to move below the trigger element and form a transmission engagement with it, placing the locking element in the triggered position. During triggering, simply driving the trigger element downwards allows it to contact and press the second end of the locking element, thereby lifting the first end of the locking element using a lever principle. The locking part disengages from the blocking mechanism, thus unlocking the blocking mechanism and triggering the device. When the pneumatic transmitter is triggered, the blocking mechanism moves in the reverse direction under the action of the return spring. With the cooperation of the elastic element, the locking part of the locking element can automatically re-engage with the blocking mechanism. The blocking mechanism can also drive the locking element to move away from the trigger element, so that the second end of the locking element moves away from the bottom of the trigger element, thus preventing the locking element from interfering with the reset of the trigger element. Compared with the prior art, the trigger element and the locking element in this design are not directly connected. This design ensures that the reset process of the trigger element and the reset process of the locking element are completely independent of each other. The reset process of the locking element is related to and synchronized with the reset process of the blocking mechanism. This not only makes the engagement speed of the locking element and the blocking mechanism faster during the reset process, which is beneficial to improving the reset efficiency, but also improves the stability and reliability of the reset process, ensuring that the locking element can smoothly engage with the blocking mechanism.

[0007] To simplify the structure, preferably, the elastic element is a tension spring, with one end connected to the locking element and the other end connected to the bracket. This allows the tension spring to pull the second end of the locking element upwards, thereby using leverage to press down the first end of the locking element. This allows the locking part of the locking element to engage with the sealing mechanism stably, achieving a more stable locking of the sealing mechanism.

[0008] Furthermore, the locking element is configured with a connecting hole for connecting the tension spring, so as to assemble and replace the tension spring.

[0009] Furthermore, the bracket is also provided with a pin for connecting the tension spring, so as to facilitate the assembly and replacement of the tension spring.

[0010] Preferably, the locking part includes a protrusion disposed at the first end of the locking member and protruding downward. This design is simple in structure and low in cost.

[0011] The second aspect of this invention addresses the problem of improving the cooperation efficiency between the locking part and the sealing mechanism. Further, the locking part includes a roller rotatably mounted on the locking component. By configuring the roller in the locking part, a limiting cooperation is formed between the roller and the sealing mechanism, allowing the roller to engage with the sealing mechanism in a rolling manner. This not only reduces friction throughout the process, facilitating smoother cooperation and reducing the likelihood of jamming, but also promotes faster engagement with the sealing mechanism, thus improving locking efficiency.

[0012] Furthermore, the locking part also includes a rotating shaft and a mounting hole constructed at the first end of the locking member, the roller being mounted on the rotating shaft and the rotating shaft being constrained by the mounting hole.

[0013] To ensure a more stable and reliable engagement between the trigger and the locking element, the bracket is further provided with a guide portion, to which the trigger is movably constrained. By using the guide portion to constrain the trigger and guide its movement, the trigger can be ensured to run more precisely along a predetermined trajectory. This not only ensures that the trigger always engages with the locking element but also enables a more stable and reliable engagement between them.

[0014] Preferably, the guide portion includes a guide hole, and the trigger and the guide hole form a sliding pair. This allows the guide hole to guide the movement of the trigger, ensuring precise movement of the trigger.

[0015] The third aspect of this utility model addresses the problem of reduced reset efficiency and stability caused by the direct connection between the trigger and locking components in existing pneumatic launchers. It provides a pneumatic launcher comprising a valve core assembly, a stop portion, a limiting portion, and the locking mechanism. The valve core assembly includes an air storage component, a sealing mechanism, and a return spring. A bracket is connected to the housing. The air storage component has an air chamber. The sealing mechanism has an exhaust port and is movably mounted on the air storage component to control whether the exhaust port communicates with the air chamber. The sealing mechanism has a groove adapted to the locking component. One end of the return spring abuts against the stop portion, and the other end abuts against the sealing mechanism. The return spring causes the sealing mechanism to abut against the limiting portion. When the air pressure inside the air chamber is greater than the external atmospheric pressure, the air pressure drives the sealing mechanism to disengage from the limiting portion and moves the locking component relative to the shaft, causing the second end of the locking component to move below the trigger. In this solution, by configuring the aforementioned locking mechanism, it can cooperate more efficiently with the blocking mechanism, resulting in higher reset efficiency and a more stable and reliable reset process.

[0016] Furthermore, it also includes a power source, which is connected to the trigger element and is used to drive the trigger element to rise and fall. Thus, the locking element can be lifted by the power source to achieve the purpose of unlocking and triggering, which is beneficial for realizing remote automatic control.

[0017] Preferably, the power source is a servo motor.

[0018] Preferably, the abutting portion is constructed on the housing; the limiting portion is constructed on the gas storage component.

[0019] Preferably, the end of the sealing mechanism is provided with a guide surface, which is used to guide the locking part into the slot during the reset process. This makes the reset process smoother and helps to improve the reset efficiency and stability.

[0020] The fourth aspect of this utility model addresses the problem of facilitating user judgment regarding whether pressurized gas is filling the gas chamber. Furthermore, the housing is equipped with an observation port corresponding to the limiting part. When no pressurized gas is filling the gas chamber, the sealing mechanism abuts against the limiting part under the action of a return spring. When pressurized gas is filling the gas chamber, the sealing mechanism disengages from the limiting part by a certain distance under the pressure of the gas, creating a gap between the sealing mechanism and the limiting part. Therefore, by configuring an observation port corresponding to the limiting part on the housing, the user can easily determine whether pressurized gas is filling the gas chamber simply by observing whether the sealing mechanism abuts against the limiting part through the observation port. This is very convenient and cost-effective.

[0021] Compared with the prior art, the locking mechanism and pneumatic launcher provided by this utility model do not have a direct connection between the trigger and the locking element. This means that during the reset process, the reset process of the trigger and the reset process of the locking element are completely independent of each other. Moreover, the reset process of the locking element is related to and synchronized with the reset process of the sealing mechanism. This not only makes the engagement speed between the locking element and the sealing mechanism faster during the reset process, which is beneficial to improving the reset efficiency, but also improves the stability and reliability of the reset process, ensuring that the locking element can smoothly engage with the sealing mechanism.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] This embodiment provides a locking mechanism 1 for a pneumatic launcher, including a bracket 2, a trigger element 3, a locking element 4, and an elastic element 51, wherein, as shown... Figures 1-3 As shown, bracket 2 serves as a load-bearing structure and is the base for installing other components. The shape of bracket 2 can be determined according to actual needs. This embodiment does not limit the shape of bracket 2.

[0034] In this embodiment, the trigger 3 is mainly used for transmission. The trigger 3 is vertically constrained by the bracket 2, allowing it to move up and down relative to the bracket 2 and the locking member 4. In this embodiment, the trigger 3 can preferably be a rod-shaped structure, such as... Figures 1-3 As shown, in implementation, the bracket 2 is also provided with a guide portion adapted to the trigger 3, so that the trigger 3 is movably constrained by the guide portion through the cooperation of the trigger 3 and the guide portion, that is, the trigger 3 and the guide portion form a sliding pair. By using the guide portion to constrain the trigger 3 and guide the movement of the trigger 3, it is ensured that the trigger 3 can run more accurately along a predetermined trajectory. This not only ensures that the trigger 3 always cooperates with the locking member 4, but also makes the trigger 3 and the locking member 4 form a more stable and reliable cooperation. In implementation, the guide portion may include a guide cylinder 21 disposed on the bracket 2, such as... Figures 1-3As shown, the guide cylinder 21 is vertically mounted on the bracket 2. The guide cylinder 21 has a guide hole 22 inside. The inner diameter of the guide hole 22 is designed to match the outer diameter of the trigger 3, so that the trigger 3 and the guide hole 22 can form a sliding pair.

[0035] For ease of description, in this embodiment, the two ends of the locking member 4 can be referred to as the first end 41 and the second end 42, respectively. The locking member 4 also has a hinge hole 43, which can be constructed between the first end 41 and the second end 42, as shown below. Figures 1-3 As shown, in this embodiment, the hinge hole 43 is not a round hole, such as... Figures 1-3 As shown, in this embodiment, the hinge hole 43 is a slotted hole. To facilitate cooperation with the sealing mechanism 8 in the pneumatic launcher, the first end 41 of the locking member 4 is constructed with a locking portion adapted to the sealing mechanism 8. In implementation, the locking portion has various embodiments. For example, in one embodiment, the locking portion may include a protrusion 44 disposed on the first end 41 of the locking member 4 and protruding downwards, such as... Figures 1-3 As shown, the protrusion 44 and the locking part 4 can be integrally molded, which has a simple structure and low cost.

[0036] like Figures 1-3 As shown, the bracket 2 is provided with a shaft 23. In implementation, the shaft 23 can be a pin 24, a rotating shaft 47, a pin, etc., provided on the bracket 2. During assembly, the locking member 4 can be sleeved on the shaft 23 through the hinge hole 43. Since the hinge hole 43 is a slotted hole, the locking member 4 can both rotate relative to the shaft 23 and move relative to the shaft 23.

[0037] In implementation, the position of the trigger 3 is adapted to the position of the locking member 4, so that when the locking member 4 moves in a direction closer to the trigger 3, the second end 42 of the locking member 4 can move below the trigger 3, as shown below. Figure 2 As shown, when the trigger 3 moves downward, it can squeeze the second end 42 of the locking member 4, thereby using the principle of leverage to lift the first end 41 of the locking member 4, thus achieving the purpose of lifting the locking part to unlock.

[0038] In this embodiment, the elastic element 51 is mainly used to press down the first end 41 of the locking element 4, making the locking part and the sealing mechanism 8 more stable and reliable, and preventing automatic disengagement and accidental triggering. In implementation, the elastic element 51 can have various embodiments. For example, the elastic element 51 can be a torsion spring, which can be sleeved on the shaft 23. When the second end 42 of the locking element 4 is pressed down (i.e., the locking element 4 rotates counterclockwise), the elastic potential energy of the torsion spring increases, and the torsion spring drives the locking element 4 to rotate clockwise. Alternatively, the elastic element 51 can also be a compression spring, with one end abutting against the locking element 4 and the other end abutting against the bracket 2. When the second end 42 of the locking element 4 is pressed down (i.e., the locking element 4 rotates counterclockwise), the elastic potential energy of the torsion spring increases, and the compression spring drives the locking element 4 to rotate clockwise. In this embodiment, the elastic element 51 is a tension spring, with one end connected to the locking element 4, such as... Figures 1-3 As shown, it can be connected to the second end 42 or a position near the second end 42; the other end of the tension spring is connected to the bracket 2 so that the second end 42 of the locking member 4 can be pulled upward by the tension spring. That is, the tension spring is used to drive the locking member 4 to rotate clockwise, so that the first end 41 of the locking member 4 can be pressed down by lever principle, so that the locking part of the locking member 4 can be locked into the sealing mechanism 8 and can be locked in a stable state, thereby achieving the purpose of more stably locking the sealing mechanism 8.

[0039] To facilitate the assembly of the tension spring, the locking member 4 is also constructed with a connecting hole 45 for connecting the tension spring, such as... Figures 1-3 As shown, this is for assembling and replacing the tension spring. Also, as... Figures 1-3 As shown, the bracket 2 is also provided with a pin 24 for connecting the tension spring, so as to assemble and replace the tension spring.

[0040] The locking mechanism 1 provided in this embodiment uses a slotted hole for the hinge hole 43, allowing the locking member 4 to not only rotate relative to the shaft 23 to move away from the unlocking and sealing mechanism 8 using a lever to achieve triggering, but also to move relative to the shaft 23. This allows control over whether the locking member 4 and the triggering member 3 can transmit power by changing the position of the locking member 4. When the air chamber of the pneumatic transmitter is inflated, the locking member 4 can move a certain distance towards the triggering member 3 under the action of air pressure, allowing the second end 42 of the locking member 4 to move below the triggering member 3. Figure 2As shown, it forms a transmission engagement with the trigger 3, and the locking member 4 is in the triggered position; when triggered, simply drive the trigger 3 to move downward, so that the trigger 3 contacts and squeezes the second end 42 of the locking member 4, thereby using the lever principle to lift the first end 41 of the locking member 4, so that the locking part disengages from the blocking mechanism 8, achieving the purpose of unlocking the blocking mechanism 8 and triggering; when the pneumatic launcher is triggered, during the reverse movement of the blocking mechanism 8 under the action of the return spring 52, with the cooperation of the elastic member 51, the locking part of the locking member 4 can automatically re-engage with the blocking mechanism 8, and the blocking mechanism 8 can also drive the locking member 4 to move away from the trigger 3, so that the second end 42 of the locking member 4 leaves the bottom of the trigger 3, as shown. Figure 3 As shown, this design ensures that the locking element 4 does not interfere with the reset of the trigger element 3. Compared to existing technologies, the trigger element 3 and the locking element 4 are not directly connected in this design. This design ensures that the reset process of the trigger element 3 is completely independent of the reset process of the locking element 4, while the reset process of the locking element 4 is related to and synchronized with the reset process of the blocking mechanism 8. This not only allows the locking element 4 and the blocking mechanism 8 to cooperate faster during the reset process, improving reset efficiency, but also enhances the stability and reliability of the reset process, ensuring that the locking element 4 can smoothly engage with the blocking mechanism 8.

[0041] Example 2

[0042] To address the issue of improving the efficiency of the cooperation between the locking part and the sealing mechanism 8, the main difference between this embodiment 2 and the above-described embodiment 1 is that, in the locking mechanism 1 provided in this embodiment, the locking part includes a roller 46 rotatably mounted on the locking member 4, such as... Figure 4 As shown, by configuring rollers 46 in the locking part, rollers 46 form a limiting fit with the sealing mechanism 8 and can be inserted into the sealing mechanism 8 in a rolling manner. This not only reduces friction throughout the process, which is conducive to achieving a smoother fit and reduces the likelihood of jamming, but also facilitates faster insertion into the sealing mechanism 8 and improves locking efficiency.

[0043] To facilitate the installation of the roller 46, in implementation, the locking part also includes a rotating shaft 47 and a mounting hole 48 constructed at the first end 41 of the locking member 4. The roller 46 is mounted on the rotating shaft 47, and the rotating shaft 47 is constrained by the mounting hole 48, as shown below. Figure 4 As shown, this allows the roller 46 to rotate relative to the locking member 4 so that it can roll along the sealing mechanism 8 to achieve rolling friction.

[0044] Example 3

[0045] This embodiment provides a pneumatic launcher, including a housing 6, a valve core assembly disposed within the housing 6, a stop part 61, a limiting part 71, and a locking mechanism 1 as described in Embodiment 1 or Embodiment 2. The valve core assembly includes an air storage component 7, a sealing mechanism 8, and a return spring 52, wherein, as... Figure 5 and Figure 6 As shown, the gas storage component 7 has a gas chamber inside. The rear end of the gas storage component 7 has a connector 72 for connecting to the gas cylinder 9, which communicates with the gas chamber. The front end of the gas storage component 7 has an exhaust channel, which communicates with the gas chamber. The rear end of the sealing mechanism 8 has a guide channel adapted to the gas storage component 7, and a valve core adapted to the exhaust channel is provided in the guide channel. The front end of the sealing mechanism 8 also has an exhaust hole, which communicates with the guide channel. The sealing mechanism 8 is sleeved on the gas storage component 7 through the guide channel, and the sealing mechanism 8 can move relative to the gas storage component 7. Simultaneously, the sealing mechanism 8 also has a slot 81 adapted to the locking part, such as... Figure 5 and Figure 6 As shown.

[0046] In implementation, the locking mechanism 1 can be housed within the housing 6, and the frame of the locking mechanism 1 is connected to the housing 6. During assembly, the gas storage component 7 can be mounted on the bracket 2 or the housing 6.

[0047] In practice, the abutment part 61 is mainly used to support the return spring 52, such as... Figure 5 and Figure 6 As shown, the return spring 52 can be sleeved on the sealing mechanism 8, and one end of the return spring 52 abuts against the abutment part 61. In implementation, the abutment part 61 can be constructed in the housing 6. For example, the abutment part 61 can be an annular step constructed in the housing 6, such as... Figure 5 and Figure 6 As shown, the other end of the return spring 52 abuts against the blocking mechanism 8. In practice, the outer side of the blocking mechanism 8 has a step adapted to accommodate the return spring 52, so that it abuts against the return spring 52. Figure 5 and Figure 6 As shown. In this embodiment, the return spring 52 is used to cause the sealing mechanism 8 to abut against the limiting part 71; in implementation, the limiting part 71 can be constructed on the housing 6 or the gas storage component 7. For example, in this embodiment, the limiting part 71 is an annular step constructed on the outside of the gas storage component 7, such as... Figure 5 and Figure 6 As shown, the end of the sealing mechanism 8 can abut against the annular step.

[0048] In a more refined embodiment, the end of the blocking mechanism 8 is provided with a guide surface 82, such as... Figure 5 and Figure 6As shown, the guide surface 82 is used to guide the locking part into the slot 81 during the reset process, making the reset process smoother and improving the reset efficiency and stability.

[0049] In a more refined implementation, a power source is also included. The power source is connected to the trigger element 3 via a transmission connection and is used to drive the trigger element 3 to rise and fall. This allows the locking element 4 to be lifted via the power source, achieving the purpose of unlocking and triggering, which is beneficial for remote automatic control. In implementation, the power source can be a motor. In this embodiment, the power source is a servo motor, which is fixed to the bracket 2 or the housing 6. The output shaft of the servo motor is connected to a connecting rod, which is connected to the trigger element 3 via a transmission connection, allowing the servo motor to drive the trigger element 3 to rise and fall via the connecting rod.

[0050] The pneumatic launcher provided in this embodiment has three states during use. State 1: When the gas cylinder 9 is not installed, the gas chamber is connected to the outside atmosphere through connector 72. At this time, the sealing mechanism 8 abuts against the limiting part 71 under the action of the return spring 52, and the locking part of the locking member 4 is engaged in the slot 81, with the locking member 4 positioned away from the trigger member 3. Figure 5 As shown;

[0051] State 2: After the gas cylinder 9 is installed, it connects to the gas chamber. The pressure inside the gas chamber gradually increases, causing the gas pressure in the gas storage component 7 to be greater than the external atmospheric pressure. At this time, the gas pressure will drive the sealing mechanism 8 to disengage from the limiting part 71 and drive the locking part 4 to move relative to the shaft part 23, so that the second end 42 of the locking part 4 moves below the trigger part 3. Figure 6 As shown, this is for subsequent excitation.

[0052] State 3: When activated, the power source drives the trigger 3 to move downward, and the trigger 3 presses the second end 42 of the locking member 4, causing the locking part of the first end 41 of the locking member 4 to disengage from the slot 81, so as to unlock the sealing mechanism 8; thereafter, the sealing mechanism 8 can move forward under the action of air pressure, so that the exhaust port is connected to the air chamber, so that the high pressure gas in the air chamber can be discharged through the exhaust port, so as to use air pressure to throw the broken glass ball out; in this process, the sealing mechanism 8 will further compress the return spring 52.

[0053] After the locking part of the locking member 4 disengages from the slot 81 of the sealing member, under the action of the elastic member 51, the locking member 4 will automatically move away from the trigger member 3 to disengage from the trigger member 3, and the first end 41 of the locking member 4 will be pressed down to press against the gas storage member 7; at the same time, after the high-pressure gas in the gas chamber is discharged instantaneously, the pressure in the gas chamber decreases, and the return spring 52 will drive the sealing mechanism 8 to move in the opposite direction (i.e., move in the direction close to the limit part 71). During the movement, the locking part of the locking member 4 is guided to re-engage into the slot 81 through the guide surface 82. Finally, the sealing mechanism 8 abuts against the limit part 71, and the valve core is re-inserted into the guide channel, so that the exhaust port is not connected to the gas chamber, and the gas pressure in the gas chamber can continue to rise, thereby returning to the above-mentioned state two, as Figure 5 As shown.

[0054] Based on this, in a more refined embodiment, the housing 6 is also provided with an observation port 62, such as... Figure 7 As shown, the observation port 62 corresponds to the limiting part 71. When the gas chamber is not filled with pressurized gas, the sealing mechanism 8 abuts against the limiting part 71 under the action of the return spring 52. When the gas chamber is filled with pressurized gas, the sealing mechanism 8 will disengage from the limiting part 71 by a certain distance under the action of gas pressure, resulting in a gap between the sealing mechanism 8 and the limiting part 71. Therefore, by configuring the observation port 62 corresponding to the limiting part 71 on the housing 6, the user only needs to check whether the sealing mechanism 8 abuts against the limiting part 71 through the observation port 62 to determine whether the gas chamber is filled with pressurized gas, which is very convenient and inexpensive. In addition, when disassembling and replacing the gas cylinder 9, the observation port 62 can be used to determine whether there is still pressurized gas in the gas chamber, so as to disassemble the gas cylinder 9 more safely.

[0055] In addition, this pneumatic launcher also includes a guide tube 21 for guiding the throwing process of the glass ball, a ball storage module for storing the glass ball, and a control module for controlling the locking mechanism 1, etc. For details, please refer to Chinese patent CN211893653U, which will not be repeated here.

[0056] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
