Description

Technical Field

[0001] This utility model relates to the field of glass breaking device technology, specifically to a shell, a main structure, and a glass breaking ball launcher. Background Technology

[0002] Glass-breaking devices (also known as glass breakers or glass-breaking ball launchers) are specialized remote glass-breaking equipment used for throwing glass-breaking balls (or high-pressure balls). They are widely used in firefighting and rescue. Currently, glass-breaking devices have diverse structures and usage methods. For example, Chinese patent CN114209996B discloses a throwing-type glass-breaking system that can be installed on a high-pressure water cannon vehicle; Chinese patent CN221579515U discloses a manually activated glass breaker that can be used handheld; and Chinese patent CN211893653U discloses a pneumatic glass-breaking ball launching mechanism that can be mounted on a drone.

[0003] Chinese patent CN211893653U discloses a pneumatic glass-breaking ball launching mechanism, which specifically includes a guide tube, a ball clamp, a power chamber (air storage component), a sealing mechanism, a return spring, a locking mechanism, and a housing. The power chamber and the sealing mechanism are mutually compatible, with the sealing mechanism 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. The guide tube, ball clamp, power chamber, sealing mechanism, and return spring are all installed in the housing. Initially, the return spring presses the sealing mechanism against the power chamber and locks the sealing mechanism, keeping the power chamber closed. The air pressure inside the power chamber can rise to the pressure required to launch the glass-breaking ball. When it is necessary to launch 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, causing the glass-breaking ball to be launched through the guide tube under the action of air pressure, thus achieving the purpose of breaking the glass. This launching mechanism can be mounted on a drone to achieve glass-breaking functionality. However, in actual use, it was found that the return spring is prone to failure, with its lifespan significantly shorter than designed, requiring frequent replacements. Actual testing revealed that the high gas pressure released from the power chamber during the activation of the glass-breaking sphere, coupled with the high-pressure gas pushing the sealing mechanism, easily causes excessive compression of the return spring. For example, the return spring may even be repeatedly crushed, especially during the first few activations, resulting in a significantly shortened lifespan. This issue urgently needs to be addressed. Summary of the Invention

[0004] The first aspect of this utility model is to solve the problem that the return spring in the existing launching mechanism is prone to failure and has a short service life. It provides a housing that can effectively protect the return spring and ensure its service life. The main concept is as follows:

[0005] A housing includes a cylindrical body and a second interface connected to the side of the cylindrical body. A channel is constructed within the cylindrical body, extending through both ends and forming a front opening and a rear opening. The second interface communicates with the channel and is used to connect a ball clamp. The inner wall of the channel has an abutment portion for abutting a return spring and a limiting portion for limiting and constraining a sealing mechanism. The abutment portion is located between the second interface and the rear opening, and the limiting portion is located between the abutment portion and the rear opening. The inner diameter of the abutment portion is at least greater than or equal to the outer diameter of the front end of the sealing mechanism, the inner diameter of the limiting portion is greater than the inner diameter of the abutment portion, and the inner diameter of the rear opening is greater than the inner diameter of the limiting portion. In this design, the valve core assembly is assembled from the rear end. In this design, a rear opening is configured to allow the valve core assembly to be installed from the rear end of the housing. This not only facilitates assembly but also reduces the volume requirements for the front end of the housing, resulting in a smaller front end volume. A front opening allows high-pressure gas to be output, enabling the throwing of the broken glass ball. A stop portion with an inner diameter at least greater than or equal to the outer diameter of the sealing mechanism's front end ensures that the stop portion does not interfere with the normal movement of the sealing mechanism. Furthermore, the stop portion can be used to position and constrain one end of the return spring for assembly. A limiting portion is configured between the stop portion and the rear opening, with its inner diameter greater than the inner diameter of the stop portion but less than the inner diameter of the rear opening. This not only avoids interfering with the assembly process of the sealing mechanism but also uses the limiting portion to constrain the sealing mechanism, thereby limiting its maximum movement distance and effectively limiting the compression of the return spring. This prevents the return spring from being frequently compressed and protects it, thus ensuring and extending its service life. In addition, compared with existing technologies, this housing has advantages such as simple structure, easy processing and molding, and easier and more efficient assembly of valve core components.

[0006] The second aspect of this invention addresses the problem of rapid assembly of the valve core assembly. Furthermore, the inner wall of the cylinder is constructed with a positioning part for positioning the gas storage component. The inner diameter of the positioning part is larger than the inner diameter of the limiting part, and the inner diameter of the rear opening is larger than the inner diameter of the positioning part. By configuring the positioning part to limit and position the gas storage component, the installation position of the entire valve core assembly can be positioned. This not only facilitates assembly of the valve core assembly from the rear end of the housing but also promotes rapid assembly of the valve core assembly.

[0007] The third aspect of this invention addresses the problem of reducing noise and vibration during the transmitter's excitation process. Furthermore, an elastic buffer layer is provided on the side of the abutment portion facing the rear opening. During excitation, the elastic buffer layer contacts the sealing mechanism, preventing a rigid collision between the sealing mechanism and the abutment portion. This effectively reduces both noise and vibration during the transmitter's excitation process, resulting in a quieter and more stable transmitter.

[0008] Preferably, the channels include a first channel, a second channel connecting to the first channel, a third channel connecting to the second channel, and a fourth channel connecting to the third channel. The inner diameter of the first channel is at least greater than or equal to the outer diameter of the front end of the blocking mechanism; the inner diameter of the second channel is greater than the inner diameter of the first channel; and the abutment portion is a step between the first and second channels. The inner diameter of the third channel is greater than the inner diameter of the second channel; and the limiting portion is a step between the second and third channels. The inner diameter of the fourth channel is greater than the inner diameter of the third channel; and the positioning portion is a step between the third and fourth channels. Using steps between the channels to form the abutment portion, limiting portion, and positioning portion not only facilitates processing and forming but also results in a simpler and more reliable structure.

[0009] Preferably, the fourth channel extends through the rear end of the cylinder. This makes the inner diameter of the rear opening equal to the inner diameter of the fourth channel, which helps simplify the manufacturing process.

[0010] To facilitate quick installation of the guide cylinder and ball clamp, the channel further includes a fifth channel connected to the first channel, extending through the front end of the cylinder, and the second interface is connected to the fifth channel. This allows for insertion installation of the guide cylinder at the front end of the housing, which not only facilitates assembly but also improves the connection strength between the guide cylinder and the housing.

[0011] Preferably, the inner diameter of the fifth channel is larger than that of the first channel. This provides more assembly space for the guide tube and the ball clamp, and also meets the throwing requirements for larger glass-breaking balls.

[0012] The fourth aspect of this utility model addresses the problem of facilitating the installation and disassembly of the gas storage component. Furthermore, the side of the cylinder is also provided with a locking hole, located between the positioning part and the rear opening, and connected to the channel. Fasteners adapted to the locking hole can be used to limit and constrain the valve core assembly, which not only facilitates quick installation and disassembly of the valve core assembly but also allows for rotatable installation of the valve core assembly.

[0013] Preferably, the front end of the cylinder is also provided with external threads to allow for the detachable installation of the guide cylinder.

[0014] Preferably, the rear end of the cylinder is also provided with external threads. This allows for the detachable installation of the gas cylinder cover, making it easier to use.

[0015] Furthermore, it also includes a fourth interface connected to the side of the cylinder, which communicates with the channel. This allows for connection to the upper housing or base via the fourth interface, further facilitating product modularization.

[0016] Preferably, the fourth interface protrudes from the outer surface of the cylinder, and the end face of the fourth interface is flat, with a threaded hole formed within the flat surface. By configuring the end face of the fourth interface as a flat surface for positioning and supporting the base, and by forming a threaded hole within the flat surface for detachable installation of the base using fasteners that fit the threaded hole, assembly and subsequent maintenance and repair are facilitated.

[0017] Preferably, the keyhole is constructed within the plane. This simplifies the structure and makes the overall structure more compact, making it more suitable for drones.

[0018] Preferably, the housing is a one-piece molded component.

[0019] A main structure includes the housing and a valve core assembly installed within the housing. The valve core assembly includes a return spring, a gas storage component, and a sealing mechanism.

[0020] The front end of the sealing mechanism has an air outlet, and the outer side of the sealing mechanism has a second mating part that is adapted to the limiting part.

[0021] The gas storage component has an internal gas chamber for storing gas, and the external side of the gas storage component has a first mating part adapted to the positioning part.

[0022] The sealing mechanism is movably fitted onto the gas storage component. A return spring is fitted onto the outside of the sealing mechanism, with one end abutting against the abutting part and the other end abutting against the sealing mechanism, used to drive the sealing mechanism to reset. Through the cooperation of the positioning part and the first mating part, the gas storage component can be quickly positioned and precisely assembled; through the cooperation of the limiting part and the second mating part, the maximum movement distance of the sealing mechanism can be limited, thereby effectively limiting the compression of the return spring and preventing it from being frequently compressed and stuck. This effectively protects the return spring and helps ensure and improve its service life.

[0023] Preferably, the second mating part is an annular boss constructed on the outside of the sealing mechanism. The outer diameter of the annular boss is larger than the inner diameter of the limiting part and smaller than the inner diameter of the positioning part. This facilitates assembly and allows for a limiting fit with the limiting part.

[0024] Preferably, the first mating part is an annular boss constructed on the outside of the gas storage component. The outer diameter of the annular boss is larger than the inner diameter of the positioning part, but smaller than the inner diameter of the rear opening. This facilitates both machining and assembly.

[0025] Furthermore, the outer side of the gas storage component has a constraint part adapted to the lock hole. The constraint part is an annular groove, and a fastener is threaded into the lock hole, with one end of the fastener inserted into the annular groove. This facilitates a simpler, more convenient, and more efficient assembly process for the valve core assembly.

[0026] Preferably, the outer side of the blocking mechanism has a slot adapted to the locking mechanism, so that the blocking mechanism can be unlocked or locked by the locking mechanism.

[0027] Furthermore, an elastic buffer layer is provided on the side of the second mating part facing the forward opening. This can prevent rigid collision between the sealing mechanism and the abutment part, which can not only effectively reduce the noise of the transmitter excitation process, but also effectively reduce the vibration of the transmitter excitation process, which is conducive to the entire transmitter being quieter and more stable.

[0028] A glass-breaking ball launcher, comprising the aforementioned main structure.

[0029] Compared with the prior art, the shell, main structure and glass ball launcher provided by this utility model can limit the maximum movement distance of the blocking mechanism, thereby effectively limiting the compression of the return spring, avoiding the situation where the return spring is frequently crushed, effectively protecting the return spring, and helping to ensure and improve the service life of the return spring.

[0044] Example 1

[0045] This embodiment provides a housing for a UAV glass-breaking ball launcher. The housing 1 mainly serves as a support and is the mounting base for other structures in the UAV glass-breaking ball launcher, such as the valve core assembly 2, air source, power source, ball clamp 5, etc. In this embodiment, the housing 1 includes a cylindrical body 10 and a second interface 17 connected to the side of the cylindrical body 10, such as... Figure 1 and Figure 2 As shown, the cylindrical body 10 preferably adopts a cylindrical structure, with the two ends of the cylindrical body 10 being the front end and the rear end, respectively. A channel constructed inside the cylindrical body 10 extends through both ends of the cylindrical body 10, forming a front opening 11 and a rear opening 12 at the front end and the rear end, respectively. In implementation, the entire shell 1 can be assembled from parts or can be a single-piece molded component, such as... Figure 1 and Figure 2 As shown, it is easy to mold and has higher strength; in implementation, the shape of the cylinder 10 can be determined according to actual needs. In implementation, the cylinder 10 can preferably adopt a cylindrical structure, such as... Figure 1 and Figure 2 As shown, the structure is simpler and the wind resistance is lower; correspondingly, in implementation, the channels inside the cylinder 10 can also be preferably constructed as cylindrical channels.

[0046] like Figure 1 and Figure 2 As shown, the second interface 17 is connected to the channel and is mainly used to connect the ball clamp 5, which is mainly used to store broken glass balls. In implementation, the second interface 17 can preferably be constructed closer to the front opening 11. The shape of the second interface 17 is adapted to the shape of the ball clamp 5. In implementation, as shown... Figure 1 and Figure 2 As shown, the second interface 17 can preferably adopt a cylindrical structure.

[0047] like Figure 1 and Figure 2 As shown, in this embodiment, the inner wall of the channel is constructed with an abutment part 13 and a limiting part 14. The abutment part 13 is mainly used to abut against the reset spring 8121 in the glass-breaking ball launcher, and the limiting part 14 is mainly used to limit and constrain the sealing mechanism 22 in the glass-breaking ball launcher. In implementation, as... Figure 1 and Figure 2 As shown, the abutment part 13 is disposed between the second interface 17 and the rear opening 12, and the limiting part 14 is disposed between the abutment part 13 and the rear opening 12. In implementation, the abutment part 13 can preferably be constructed as a ring-shaped structure or an arc-shaped structure, and similarly, the limiting part 14 can preferably be constructed as a ring-shaped structure or an arc-shaped structure. In implementation, the inner diameter of the abutment part 13 is at least greater than or equal to the outer diameter of the front end of the sealing mechanism 22, such as... Figure 1 and Figure 2 As shown; the inner diameter of the limiting part 14 is larger than the inner diameter of the abutting part 13, as... Figure 2As shown, the inner diameter of the rear opening 12 is larger than the inner diameter of the limiting part 14, as... Figure 2 As shown, the inner diameter of the cylinder 10 increases gradually along the direction close to the rear opening 12, thereby facilitating the assembly of the valve core assembly 2 into the cylinder 10 from the rear end of the cylinder 10.

[0048] In a further embodiment, the inner wall of the cylinder 10 is also provided with a positioning part 15 for positioning the gas storage component 26, as shown in the figure. Similarly, the positioning part 15 can preferably be constructed as a ring-shaped structure or an arc-shaped structure, etc. In implementation, the inner diameter of the positioning part 15 is larger than the inner diameter of the limiting part 14, and the inner diameter of the rear opening 12 is larger than the inner diameter of the positioning part 15, such as... Figure 2 As shown, this is so that the valve core assembly 2 can be assembled into the cylinder 10 from the rear end of the cylinder 10.

[0049] To facilitate the high-precision and rapid formation of the abutment 13, limiting part 14, and positioning part 15, the channel may include a first channel 101, a second channel 102 connecting the first channel 101, a third channel 103 connecting the second channel 102, and a fourth channel 104 connecting the third channel 103, such as... Figure 1 and Figure 2 As shown, the inner diameter of the first channel 101 is at least greater than or equal to the outer diameter of the front end of the blocking mechanism 22, so that the front end of the blocking mechanism 22 can pass smoothly through the first channel 101. In some cases, the first channel 101 can also serve as a guide for the blocking mechanism 22. Simultaneously, the inner diameter of the second channel 102 is greater than the inner diameter of the first channel 101, thereby forming a step between the first channel 101 and the second channel 102. This step forms the abutment part 13, such as... Figure 2 As shown. Similarly, the inner diameter of the third channel 103 is larger than the inner diameter of the second channel 102, so that a step can also be formed between the second channel 102 and the third channel 103. This step can form the limiting part 14, as shown. Figure 2 As shown. The inner diameter of the fourth channel 104 is larger than the inner diameter of the third channel 103, thus allowing a step to be formed between the third channel 103 and the fourth channel 104, which can form the positioning part 15. In implementation, the inner diameter of the rear opening 12 can be larger than or equal to the inner diameter of the fourth channel 104. In this case, the fourth channel 104 penetrates the rear end of the cylinder 10, as shown. Figure 2 As shown.

[0050] In one embodiment, the end of the first channel 101 that is away from the second channel 102 can penetrate through the front end of the cylinder 10. In this case, the second interface 17 can be set at the position corresponding to the first channel 101 and connected to the first channel 101.

[0051] In another preferred embodiment, the channel further includes a fifth channel 105 connected to the first channel 101. The fifth channel 105 is located at the end opposite to the second channel 102 and extends through the front end of the cylinder 10. Figure 2 As shown, the second interface 17 is connected to the fifth channel 105. In practice, the inner diameter of the fifth channel 105 can be smaller or larger than the inner diameter of the first channel 101, as shown in the figure. This provides more assembly space for the guide tube 3 and the ball clamp 5, and also meets the throwing requirements of larger-sized glass breaking balls.

[0052] like Figure 2 As shown, in practice, the first channel 101, the second channel 102, the third channel 103, the fourth channel 104, and the fifth channel 105 are coaxial.

[0053] To facilitate the installation and disassembly of the gas storage component 26, a locking hole 16 is also constructed on the side of the cylinder 10 during implementation. The locking hole 16 is located between the positioning part 15 and the rear opening 12 and is connected to the channel, such as... Figure 2 As shown, the lock hole 16 can be connected to the fourth channel 104; during assembly, the valve core assembly 2 can be constrained in the vertical direction using the fastener 9 that is adapted to the lock hole 16, such as... Figure 2 As shown, this not only facilitates quick installation and disassembly of the valve core assembly 2, but also allows for rotatable installation of the valve core assembly 2. In implementation, the locking hole 16 can preferably be a threaded hole 108, and correspondingly, the fastener 9 can preferably be a bolt or screw adapted to the threaded hole 108.

[0054] To facilitate the installation and removal of the guide cylinder 3 in the glass-breaking ball launcher, the front end of the cylinder 10 is also constructed with an external thread 19, such as... Figure 1 and Figure 2 As shown, the guide cylinder 3 is constrained and fixed by means of a threaded connection.

[0055] Similarly, to facilitate the installation and removal of the gas cylinder sleeve 4 in the glass-breaking ball launcher, an external thread 19 is also constructed at the rear end of the cylinder 10 during implementation, such as... Figure 1 and Figure 2 As shown, this is to constrain and secure the gas cylinder sleeve 4 via a threaded connection.

[0056] In a more refined embodiment, the housing 1 further includes a fourth interface 18 connected to the side of the cylinder 10, such as... Figure 1 and Figure 2 As shown, the fourth interface 18 is connected to the channel, and can be specifically set at the position corresponding to the second channel 102 and the third channel 103, such as... Figure 2As shown, the fourth interface 18 is mainly used to connect the upper frame or upper housing 6 in the glass-breaking ball launcher. The upper frame and upper housing 6 are used to support the power source in the glass-breaking ball launcher, etc., and can serve as the mounting base for internal components. In implementation, the second interface 17 and the fourth interface 18 can be constructed on both sides of the cylinder 10, for example, the second interface 17 and the fourth interface 18 can be set on the lower and upper sides of the cylinder 10, respectively, or the second interface 17 and the fourth interface 18 can be set on the left and upper sides of the cylinder 10, respectively.

[0057] like Figure 1 and Figure 2 As shown, the fourth interface 18 protrudes from the outer surface of the cylinder 10. The end face of the fourth interface 18 is flat, as shown, to position and support the base. A threaded hole 108 is constructed within this flat surface to allow for the detachable installation of the base using fasteners 9 that fit the threaded hole 108, facilitating assembly and subsequent maintenance. In practice, the locking hole 16 can penetrate the flat surface, as shown... Figure 2 As shown, this reduces the need to machine one less threaded hole 108 in the plane, which simplifies the structure and makes the overall structure more compact and suitable for drones.

[0058] In implementation, the entire housing 1 can preferably be made of aluminum alloy or steel.

[0059] In implementation, the second interface 17 can also be configured with a snap-fit ​​structure for locking and unlocking the ball clamp 5, so as to enable quick installation and removal of the ball clamp 5, and to facilitate the installation and replacement of the ball clamp 5. In implementation, the snap-fit ​​structure can be implemented using existing technology, which will not be elaborated here.

[0060] Example 2

[0061] This embodiment provides a main structure, including a valve core assembly 2 and a housing 1 as in Embodiment 1. The valve core assembly 2 can be installed inside the housing 1, such as... Figure 6 and Figure 7 As shown, as an example, the valve core assembly 2 includes a return spring 8121, an air storage component 26 and a blocking mechanism 22. The front end of the blocking mechanism 22 is provided with an air outlet 23. The air storage component 26 is provided with an air chamber for storing high-pressure gas. The blocking mechanism 22 is movably disposed on the air storage component 26. The movement of the blocking mechanism 22 controls whether the air outlet 23 is connected to the air chamber.

[0062] like Figures 5-7 As shown, the outer surface of the gas storage component 26 is constructed with a constraint portion adapted to the lock hole 16. The constraint portion can be a hole or a groove, for example, as shown in the figure. Figures 5-7As shown, the constraint part is an annular groove 27 constructed on the outer side of the gas storage component 26, so that when the valve core assembly 2 is installed, no matter what angle the valve core assembly 2 is at, the fastener 9 connected to the lock hole 16 can be inserted into the annular groove 27, thereby preventing the valve core assembly 2 from coming out of the housing 1, thus making the assembly process simpler, more convenient and efficient.

[0063] like Figures 5-7 As shown, the outer surface of the gas storage component 26 is also provided with a first mating part 28 adapted to the positioning part 15. During assembly, the first mating part 28 of the gas storage component 26 abuts against the positioning part 15, and the positioning part 15 positions the gas storage component 26. When the first mating part 28 of the gas storage component 26 abuts against the positioning part 15, the locking hole 16 corresponds exactly to the restraining part, so as to be locked by the fastener 9. In implementation, the first mating part 28 can be an annular boss constructed on the outside of the gas storage component 26, and the outer diameter of the annular boss is larger than the inner diameter of the positioning part 15, such as... Figures 5-7 As shown, it is easy to process and shape.

[0064] like Figures 5-7 As shown, the outer side of the blocking mechanism 22 has a second mating part 24 adapted to the limiting part 14. During assembly, the second mating part 24 can be an annular boss constructed on the outer side of the blocking mechanism 22. The outer diameter of the annular boss is larger than the inner diameter of the limiting part 14 and smaller than the inner diameter of the positioning part 15, such as... Figures 5-7 As shown, this design facilitates both assembly and positioning with the limiting part 14. Initially, the second mating part 24 corresponds to the limiting part 14, and there is a predetermined distance between them. Furthermore, the outer side of the sealing mechanism 22 has a slot 25 adapted to the locking mechanism, such as... Figures 5-7 As shown, the slot 25 is constructed between the second mating part 24 and the rear end of the sealing mechanism 22.

[0065] like Figures 5-7 As shown, the reset spring 8121 is sleeved on the outside of the sealing mechanism 22 and is mainly used to drive the sealing mechanism 22 to reset.

[0066] During assembly, the valve core assembly 2 can be inserted into the housing 1 through the rear opening 12. When the gas storage component 26 abuts against the positioning part 15, the gas storage component 26 can be locked by the fastener 9 of the adapter constraint part. At this time, one end of the return spring 8121 abuts against the abutment part 13, and the other end of the return spring 8121 abuts against the sealing mechanism 22, for example, it can abut against the second mating part 24 of the sealing mechanism 22. The sealing mechanism 22 abuts against the gas storage component 26 under the action of the return spring 8121. For example, the rear end of the sealing mechanism 22 can abut against the first mating part 28 of the gas storage component 26. Figure 6As shown, the front end of the blocking mechanism 22 corresponds to or is inserted into the first channel 101; when triggered, the blocking mechanism 22 can be inserted into the first channel 101 or continue to be inserted into the first channel 101 under the action of air pressure. When the blocking mechanism 22 moves to the contact limit part 14, it will be blocked by the limit part 14, restricting the blocking mechanism 22 from continuing to move, as shown. Figure 7 As shown, this effectively prevents the return spring 8121 from being crushed, greatly reduces the compression of the return spring 8121, and achieves the purpose of protecting the return spring 8121 and improving its service life.

[0067] When the gas supply device 41 in the glass-breaking ball launcher uses a gas cylinder, the valve core assembly 2 also includes a connector 29 located at the rear end of the gas storage component 26, such as... Figures 5-7 As shown, so that the gas cylinder can be connected via connector 29.

[0068] To reduce noise and vibration during the transmitter's excitation process, an elastic buffer layer is provided between the abutment part 13 and the second mating part 24. During excitation, the elastic buffer layer contacts the sealing mechanism 22, preventing a rigid collision between the sealing mechanism 22 and the abutment part 13. This effectively reduces both noise and vibration during the transmitter's excitation process, resulting in a quieter and more stable transmitter. The elastic buffer layer can be located on the side of the abutment part 13 facing the rear opening 12, or on the side of the second mating part 24 facing the front opening 11. Preferably, the elastic buffer layer is made of rubber or silicone.

[0069] Example 3

[0070] This embodiment provides a glass-breaking ball launcher, including a guide cylinder 3, a ball clamp 5, a protective sleeve 4, and the main structure described in Embodiment 2. The guide cylinder 3 is detachably mounted on the front end of the housing 1 and communicates with the channel. Figures 8-11 As shown; the ball clamp 5 is detachably installed on the second interface 17 and connected to the channel so as to supply broken glass balls into the housing 1.

[0071] In implementation, it also includes a locking nut 32 adapted to the front opening 11, and at the same time, the side of the guide cylinder 3 is constructed with an annular retaining ring 31, such as Figures 8-11 As shown, the portion between the annular retaining ring 31 and the rear end of the guide cylinder 3 is configured to fit the fifth channel 105. For example, the outer diameter of the rear end of the guide cylinder 3 can be configured to be less than or equal to the inner diameter of the fifth channel 105, so that the rear end of the guide cylinder 3 can be inserted into the fifth channel 105. The locking nut 32 can be threaded to the front end of the housing 1 and can press the annular retaining ring 31 against the end of the front opening 11. Figures 8-11As shown, this enables the guide cylinder 3 to be detachably connected and can improve the connection strength between the guide cylinder 3 and the housing 1.

[0072] In this embodiment, the ball clamp 5 is mainly used to store broken glass beads and supply broken glass beads into the housing 1; the side of the top of the ball clamp 5 has corresponding ball outlet and air inlet. The top of the ball clamp 5 can be inserted into the housing 1 through the second interface 17. When the top of the ball clamp 5 abuts against the inner wall of the housing 1, the ball outlet faces the guide cylinder 3, and the air inlet faces the front end of the sealing mechanism 22. Figures 8-11 As shown, the rear end of the guide cylinder 3 can abut against the ball clamp 5. Simultaneously, the ball clamp 5 can be locked to the housing 1 via a snap-fit ​​structure, facilitating quick replacement of the ball clamp 5 or replenishment of broken glass balls into it. In implementation, the snap-fit ​​structure can be implemented using existing technology. For example, the snap-fit ​​structure may include a spring 81, a locking rod 7, a cover 8, a first slide rail 106 constructed on the inner wall of the second interface 17, and a second slide rail 107 connected to and perpendicular to the first slide rail 106. Figures 8-11 As shown, the lower end of the locking rod 7 is located within the second slide rail 107, the spring 81 is located at the bottom of the second slide rail 107 and supports the locking rod 7, the cover 8 is installed on the housing 1, and the upper end of the locking rod 7 extends out of the cover 8; the side of the locking rod 7 has a locking block 71, as shown... Figure 9 As shown, one side of the locking block 71 has a guide surface 72, and the side opposite to the guide surface 72 has a limiting surface, which can be a vertical plane, to restrict the slider 51. Initially, the locking rod 7 is pressed against the cover 8 by the elastic force of the spring 81. The guide surface 72 corresponds to the second slide rail 107, and the guide surface 72 faces the outside of the second interface 17. At the same time, the side of the ball clamp 5 has a slider 51 adapted to the first slide rail 106. During the process of the ball clamp 5 being inserted into the second interface 17, the slider 51 moves along the first slide rail 106 and presses the guide surface 72, thereby driving the locking rod 7 to move downward and compress the spring 81, so that the slider 51 can pass smoothly through the locking block 71. The locking block 71 can automatically reset after the slider 51 passes to lock the slider 51. Figure 10 As shown, this achieves the purpose of quickly locking the ball clamp 5. When it is necessary to remove the ball clamp 5, simply press down on the locking lever 7 to unlock the ball clamp 5, which is very convenient.

[0073] In this embodiment, the sheath 4 has an inner cavity for accommodating the air supply device 41, and the sheath 4 is threaded to the rear end of the housing 1, such as... Figure 8 and Figure 11 As shown, a gas supply device 41 for providing high-pressure gas is provided inside the sheath 4. The gas supply device 41 can be connected to the valve core assembly 2. In implementation, a high-pressure gas cylinder can be preferentially used as the gas supply device 41.

[0074] In a more complete solution, an upper housing 6 is also included. The upper housing 6 is connected to the fourth interface 18 and communicates with the upper housing 6 through the fourth interface 18, such as... Figure 8 As shown, the upper housing 6 contains an upper frame and a power source, etc.

[0075] Of course, in a more complete implementation, it also includes a locking mechanism adapted to the valve core assembly 2, a power source for driving the locking mechanism, a control module that plays a control role, etc. The locking mechanism includes a hinged locking rod 91, which can be referred to in Chinese patent CN211893653U, and will not be described in detail here.

[0076] 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.
