Description

Technical Field

[0001] This utility model relates to the technical field of glass ball launching devices, specifically to a glass ball launching device. Background Technology

[0002] A glass-breaking device (or glass-breaking equipment, glass-breaking ball launcher) is a specialized long-range glass-breaking device used for launching 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 is a glass-breaking device that can be mounted on a drone. This launching mechanism specifically includes a guide tube, a ball magazine, a power chamber (air storage component), a sealing mechanism, a locking mechanism, and a housing. The power chamber and the sealing mechanism are mutually compatible, and the sealing mechanism is movably mounted on... One end of the power chamber is used to seal and open the power chamber; the locking mechanism is compatible with the sealing mechanism and is used to lock and unlock the sealing mechanism; when the locking mechanism locks the sealing mechanism, the power chamber is closed, and the air pressure in 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, and the sealing mechanism moves under the action of the air pressure in the power chamber and releases the high-pressure gas in the power chamber. The high-pressure gas acts on the glass-breaking ball at the top of the ball box, so that the glass-breaking ball is thrown out through the guide tube under the action of air pressure, so as to achieve the purpose of breaking the glass.

[0003] Currently, glass-breaking balls have diverse structures, many of which are irregularly shaped. Irregularly shaped glass-breaking balls typically achieve better glass-breaking effects. For example, a high-drilling ball with a regular hexahedral lateral surface disclosed in Chinese patent CN211893653U can achieve a more efficient glass-breaking effect and is widely used in practice. However, the irregularly shaped glass-breaking balls place higher demands on the glass-breaking ball launcher. For instance, a higher precision correspondence between the guide tube and the ball magazine is required; otherwise, problems such as high kinetic energy loss or even jamming during the launch can easily occur. Existing designs usually require repeated adjustments to the installation angle of the guide tube to ensure it aligns well with the ball magazine, resulting in cumbersome assembly, low efficiency, and difficulty in ensuring strict alignment between the guide tube and the ball gate, severely affecting the launching and glass-breaking effects. These issues urgently need to be addressed. Summary of the Invention

[0004] The first aspect of this utility model is to solve the above-mentioned problems by providing a glass-breaking ball launcher that can ensure strict alignment between the guide cylinder and the ball gate. This not only simplifies and simplifies the assembly process but also helps reduce the kinetic energy loss of the glass-breaking ball, allowing it to be thrown farther and achieving a better glass-breaking effect. The main concept is as follows:

[0005] A glass-breaking ball launcher includes a launching body, a guide tube, and a ball gate. The launching body includes a shell with an inner cavity, a first interface adapted to the guide tube, and a second interface adapted to the ball gate. The first and second interfaces are respectively connected to the inner cavity. The first interface has a first positioning part, the guide tube has a second positioning part adapted to the first positioning part, and the guide tube has a throwing channel adapted to the glass-breaking ball. The guide tube is positioned by the cooperation of the first and second positioning parts, and is detachably installed in the shell. The rear end of the guide tube is inserted into the inner cavity through the first interface. The second interface has a third positioning part, and the ball gate has a fourth positioning part adapted to the third positioning part. The ball gate has a cavity for storing glass-breaking balls, and the upper side of the ball gate has a ball outlet and a vent adapted to the glass-breaking ball, with the ball outlet corresponding to the vent. The ball gate is positioned by the cooperation of the third and fourth positioning parts, and is detachably installed in the shell. The upper end of the ball gate is inserted into the inner cavity through the third interface. The throwing channel corresponds to the ball outlet. In this design, the cooperation of the first and second positioning parts allows for precise positioning of the guide cylinder's installation position and angle; the cooperation of the third and fourth positioning parts allows for precise positioning of the ball gate's installation position and angle. This ensures that the throwing channel in the guide cylinder is precisely aligned with the ball exit in the ball gate. On one hand, during assembly, there is no need to manually adjust the installation angle of either the guide cylinder or the ball gate, making the assembly process simpler, more convenient, and more efficient. On the other hand, the shapes of the throwing channel and ball exit can be designed to better suit the shape of the glass-breaking ball. This helps prevent the glass-breaking ball from rotating during its passage through the guide cylinder, resulting in a more accurate throwing trajectory. It also effectively reduces friction and avoids collisions, thus reducing the kinetic energy loss of the glass-breaking ball and allowing it to be thrown farther for better glass-breaking results. The detachable installation of the guide cylinder onto the housing facilitates the separate manufacturing of the guide cylinder and housing, reducing costs and improving processing accuracy. The detachable installation of the ball gate onto the housing facilitates installation and replacement, making it easier to use.

[0006] Preferably, the rear end of the guide tube abuts against the side of the ball gate. This minimizes the gap between the throwing channel and the ball outlet, reducing resistance to the broken glass ball, preventing collisions and jamming, and facilitating a smoother throw.

[0007] Preferably, the guide cylinder is perpendicular to the ball gate.

[0008] Preferably, the cross-sectional shape of the throwing channel is the same as the cross-sectional shape of the ball outlet.

[0009] Preferably, the throwing channel and the ball outlet are both hexagonal in shape. This design is to accommodate the hexagonal glass-breaking ball, which facilitates a longer throwing distance and better glass-breaking effect.

[0010] Preferably, the first positioning part includes at least two positioning blocks constructed at the end of the first interface; the second positioning part includes positioning holes or positioning notches that adapt to the positioning blocks. This allows for precise positioning of the guide cylinder's installation position and angle through the cooperation of the first and second positioning parts.

[0011] Preferably, each positioning block is evenly distributed along the circumference of the first interface. This helps to achieve a more accurate positioning effect.

[0012] To address the issue of the ball gate failing to insert due to excessive insertion of the guide cylinder, a limiting part is further provided on the outer side of the guide cylinder, abutting against the end of the first interface. By configuring the limiting part to limit the guide cylinder, it ensures that during assembly, the guide cylinder has a fixed insertion depth, precisely matching the ball gate's insertion depth, effectively solving the problem of the ball gate failing to insert due to excessive insertion of the guide cylinder.

[0013] Furthermore, it also includes a locking cover. The outer surface of the first interface has external threads, and the locking cover has a threaded hole adapted to the first interface. One end of the threaded hole has a retaining ring adapted to the limiting part. The locking cover is threaded to the first interface, and the retaining ring presses the limiting part against the end of the first interface. This not only facilitates the installation and removal of the guide cylinder, but also allows the limiting part to be pressed against the end of the first interface, so as to accurately position and limit the guide cylinder, thereby improving assembly accuracy.

[0014] Preferably, the limiting part is constructed as an annular step.

[0015] Preferably, the second positioning part is constructed on the limiting part. This simplifies the structure, reduces weight and volume, and is more suitable for use on drones.

[0016] Preferably, the third positioning part includes a positioning channel constructed on the inner sidewall of the second interface, the positioning channel being arranged along the length direction of the second interface; the fourth positioning part includes a positioning slider adapted to the positioning channel. The cooperation between the positioning slider and the positioning channel plays a positioning and guiding role in the installation process of the ball gate, ensuring that the ball gate is always inserted into the second interface in a preset orientation, thus eliminating orientational deviation during insertion and facilitating precise alignment between the ball gate and the guide cylinder.

[0017] The second aspect of this invention addresses the problem of facilitating the installation and disassembly of the ball gate. Furthermore, the second interface is equipped with a snap-fit ​​structure adapted to the positioning slider, which locks and unlocks the positioning slider. In this solution, the positioning slider not only cooperates with the positioning channel for positioning and guiding, but also cooperates with the snap-fit ​​structure to lock and unlock the positioning slider, thereby achieving the purpose of quickly locking and unlocking the ball gate; this also simplifies the structure and reduces costs.

[0018] Preferably, the latching structure includes a spring, a locking rod, a cover component, and an assembly hole constructed in the second interface. The assembly hole is perpendicular to and communicates with the positioning channel. The locking rod has a limiting step and a locking block, and a guide surface is constructed on one side of the locking block. The lower end of the locking rod is disposed in the assembly hole, the spring is disposed at the bottom of the assembly hole and supports the locking rod, the cover component has an opening, the cover component is fixed to the housing, the limiting step of the locking rod abuts against the cover component, the upper end of the locking rod extends out of the cover component through the opening, and the guide surface corresponds to the positioning channel and faces the outside of the second interface. In this design, a cover component facilitates the installation and removal of the locking rod. A spring is incorporated, with a limiting step on the locking rod, and the spring supports the rod. The spring presses the locking rod upwards against the cover component. This serves two purposes: firstly, it keeps the locking block in a limiting constraint state on the positioning slider, ensuring a stable locking state for the ball gate; secondly, it allows the locking rod to move downwards under external force, causing the locking block to leave the positioning channel and releasing the limiting constraint on the positioning slider, facilitating quick unlocking of the ball gate and easy replacement. Furthermore, a guide surface is constructed on one side of the locking block, corresponding to the positioning channel and facing outwards from the second interface. During the insertion of the ball gate into the second interface, the positioning slider presses against the guide surface, driving the locking rod downwards and compressing the spring. This allows the positioning slider to pass smoothly through the locking block, which automatically resets after the slider passes, locking the slider again, thus achieving rapid locking of the ball gate.

[0019] Preferably, the cover component has a through hole, and the side of the second interface has a threaded hole. The cover component is threadedly connected to the housing by fasteners that fit the through hole and the threaded hole, so as to facilitate the installation and removal of the cover component.

[0020] Preferably, the ball gate includes a housing, a ball holder for supporting the broken glass balls, and an end cap. The upper end of the housing is closed, the ball outlet and the vent are respectively constructed on the side of the upper end of the housing, and the end cap is threaded to the lower end of the housing. The housing and the end cap form a cavity, and the ball holder is disposed in the cavity. An elastic element is provided between the ball holder and the end cap to press the broken glass balls stored in the cavity upwards using the elastic element.

[0021] Furthermore, the launching body also includes a valve core assembly, and the housing is also configured with a third interface, which is connected to the inner cavity. The first interface and the third interface are located at the two ends of the inner cavity, and the first interface and the third interface are coaxial. The valve core assembly is installed in the inner cavity, the front end of the valve core assembly corresponds to the vent, the rear end of the valve core assembly is provided with a connector for connecting the gas cylinder, and the third interface is used to connect the gas cylinder sleeve.

[0022] Furthermore, it also includes a gas cylinder sleeve, which has an internal cavity for accommodating the gas cylinder. The gas cylinder sleeve is threaded to a third interface, and the connector communicates with the cavity. This facilitates the installation and replacement of the gas cylinder.

[0023] Compared with existing technologies, the glass-breaking ball launcher provided by this utility model can ensure that the guide tube and the ball gate are strictly aligned, which not only makes the assembly process simpler, more convenient and efficient, but also helps to reduce the kinetic energy loss of the glass-breaking ball, thereby helping to throw the glass-breaking ball farther and achieve a better glass-breaking effect.

[0039] 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.

[0040] Example 1

[0041] This embodiment provides a glass-breaking ball launcher, including a launching body 1, a guide cylinder 3 and a ball gate 4. The launching body 1 includes a housing 2, a valve core assembly, a locking mechanism, etc.

[0042] like Figure 2 and Figure 3 As shown, the housing 2 has an inner cavity 21, a first interface 22 for the guide cylinder 3, and a second interface 25 for the ball gate 4. The first interface 22 and the second interface 25 are respectively connected to the inner cavity 21. In implementation, the first interface 22 can be preferably constructed at the front end of the housing 2, as shown in the figure, and the second interface 25 can be preferably constructed at the lower end of the housing 2. The first interface 22 and the second interface 25 are preferably perpendicular to each other, so that the guide cylinder 3 inserted into the first interface 22 is also perpendicular to the ball gate 4 inserted into the second interface 25. Figure 2 As shown, after the glass-breaking ball 9 enters the guide cylinder 3 from the ball gate 4, the tip of the glass-breaking ball 9 is exactly aligned with the center of the guide cylinder 3, so that the glass-breaking ball 9 thrown out of the guide cylinder 3 has a better posture, so as to achieve a better glass-breaking effect.

[0043] In implementation, the first interface 22 is equipped with a first positioning part, and the guide cylinder 3 is equipped with a second positioning part adapted to the first positioning part. During assembly, the cooperation between the first and second positioning parts allows for precise positioning of the guide cylinder 3's installation position and angle, especially its installation angle, making it more suitable for irregularly shaped glass-breaking spheres 9. For example, in this embodiment, the glass-breaking sphere 9 is a high-precision sphere with a regular hexahedral lateral surface, such as... Figure 1 As shown; the guide tube 3 has a throwing channel 31 extending through both ends, and the throwing channel 31 is designed to fit the shape of the glass-breaking ball 9, as shown. Figure 5 and Figure 6 As shown, the throwing channel 31 is constructed in the form of a regular hexagon to accommodate the high-diameter ball. When the high-diameter ball moves along the throwing channel 31, it will not rotate within the throwing channel 31, but will only move in a straight line relative to the guide cylinder 3. This helps to reduce the kinetic energy loss of the broken glass ball 9 and helps to throw the broken glass ball 9 further.

[0044] In implementation, the first positioning part and the second positioning part can have various cooperative implementation methods. For example, the first positioning part may include at least two positioning blocks 23 constructed at the end of the first interface 22, such as... Figure 2 As shown, in implementation, each positioning block 23 can be evenly distributed along the circumference of the first interface 22, which is beneficial for achieving a more precise positioning effect. Correspondingly, the second positioning part may include positioning holes or positioning notches 33 that adapt to the positioning blocks 23, such as... Figure 5 and Figure 6As shown, during assembly, the positioning block 23 can be inserted into the corresponding positioning hole or positioning notch 33 to accurately position the installation position and angle of the guide cylinder 3 through the cooperation of the first positioning part and the second positioning part. Of course, in practice, the first positioning part can also be configured to include a positioning hole or positioning notch 33, and correspondingly, the second positioning part can be configured to include a positioning block 23 that fits the positioning hole or positioning notch 33, which can also achieve the same positioning effect.

[0045] In this embodiment, the rear end of the guide cylinder 3 can be inserted into the inner cavity 21 through the first interface 22, which helps to improve the connection strength between the guide cylinder 3 and the housing 2; the guide cylinder 3 is detachably installed on the housing 2, so that the guide cylinder 3 and the housing 2 can be manufactured separately, which helps to reduce costs and improve processing accuracy. In implementation, at least the outer diameter of the rear end of the guide cylinder 3 is constructed to be less than or equal to the inner diameter of the first interface 22, so that the rear end of the guide cylinder 3 can be inserted into the inner cavity 21 through the first interface 22, such as Figure 12 and Figure 13 As shown. After the guide cylinder 3 is inserted into place, it can be horizontally locked by the tightening bolts that are threaded to the housing 2, thereby fixing the guide cylinder 3.

[0046] However, in order to precisely control the insertion depth of the guide cylinder 3, in this embodiment, a limiting part 32 is also provided on the outer side of the guide cylinder 3, such as... Figure 5 and Figure 6 As shown, the limiting part 32 can abut against the end of the first interface 22. By configuring the limiting part 32, the guide cylinder 3 is limited, ensuring that during assembly, the guide cylinder 3 has a fixed insertion depth, which can be precisely aligned with the ball gate 4. This effectively solves the problem that the guide cylinder 3 is easily inserted too deeply, causing the ball gate 4 to be unable to be inserted. In implementation, the limiting part 32 can be constructed as an annular step, such as... Figure 5 and Figure 6 As shown, the entire guide cylinder 3 can be constructed as a stepped structure. Of course, in practice, the limiting part 32 can also be constructed as a block structure, etc., which will not be illustrated here. In practice, the second positioning part can be preferentially constructed within the limiting part 32, such as... Figure 5 and Figure 6 As shown, this design simplifies the structure, reduces weight and volume, and makes it more suitable for use on drones.

[0047] Based on this, in a more preferred embodiment, a locking cover 34 is also included, and the outer surface of the first interface 22 is provided with external threads 24, such as... Figure 7 As shown, the locking cover 34 has a threaded hole 35 adapted to the first interface 22, and one end of the threaded hole 35 has a retaining ring 36 adapted to the limiting part 32; during assembly, the locking cover 34 can be threaded to the first interface 22, and the retaining ring 36 can press the limiting part 32 against the end of the first interface 22, as shown. Figures 2-4 As shown, this design not only facilitates the installation and disassembly of the lock guide cylinder 3, but also allows the limiting part 32 to be pressed against the end of the first interface 22, so as to accurately position and limit the guide cylinder 3 and improve assembly accuracy.

[0048] In implementation, the second interface 25 is equipped with a third positioning part, and correspondingly, the ball gate 4 is equipped with a fourth positioning part adapted to the third positioning part. During assembly, the installation position and installation angle of the ball gate 4 can be precisely positioned by the cooperation of the third positioning part and the fourth positioning part, which is especially suitable for irregularly shaped glass-breaking balls 9. In this embodiment, the upper side of the ball gate 4 is equipped with a ball outlet 42 and a vent 43 adapted to the glass-breaking ball 9, with the ball outlet 42 corresponding to the vent 43, such as... Figure 8 and Figure 9 As shown, the outlet 42 is mainly used to allow the glass breaker to enter the guide tube 3, and the vent 43 is mainly used to connect to the valve core assembly so that high-pressure gas can be connected through the valve core assembly. In implementation, the vent 43 can be directly opposite the outlet 42, and the shape of the vent 43 can be the same as or different from the outlet 42. For example, in this embodiment, since the glass breaker 9 is a high-precision ball with a regular hexahedral lateral surface, the outlet 42 is constructed as a regular hexagonal structure to adapt to the shape of the glass breaker 9, such as... Figure 8 and Figure 9 As shown, the vent 43 can be constructed as a regular hexagonal structure or as a round hole, etc. In this embodiment, the vent 43 is also constructed as a regular hexagonal structure, which is more convenient for processing and reduces costs.

[0049] In this embodiment, the ball gate 4 has a cavity 46 for storing the broken glass ball 9. The ball gate 4 can preferably be constructed as a cylindrical structure, such as... Figure 8 and Figure 9 As shown, multiple broken glass balls 9 can be stored in a stacked manner within the cavity 46. For example, in this embodiment, the ball gate 4 includes a housing 41, a ball support for supporting the broken glass balls 9, and an end cap 45, as shown... Figure 8 and Figure 9 As shown, the upper end of the housing 41 is closed, the ball outlet 42 and the vent 43 are respectively constructed on the side of the upper end of the housing 41, and the end cap 45 is threaded to the lower end of the housing 41. The housing 41 and the end cap 45 form the cavity 46. The ball holder is disposed in the cavity 46, and an elastic element is disposed between the ball holder and the end cap 45. In implementation, the elastic element can preferably be a spring 7, so that the elastic element can be used to press the broken glass balls 9 stored in the cavity 46 upward, so that after the uppermost broken glass ball 9 is thrown out, the broken glass balls 9 located in the lower layer can automatically rise to the top and correspond to the guide tube 3 for the next throw.

[0050] In implementation, the third and fourth positioning parts can have various cooperative implementation methods. For example, the third positioning part can be a positioning hole constructed at the end of the second interface 25, and the fourth positioning part can be a positioning block 23 constructed on the side of the ball gate 4, with positioning achieved through the cooperation of the positioning hole and the positioning block 23. As another example, in this embodiment, the third positioning part includes a positioning channel 26 constructed on the inner wall of the second interface 25, such as... Figure 3 , Figure 11 and Figure 13 As shown, the positioning channel 26 is arranged along the length direction of the second interface 25; correspondingly, the fourth positioning part includes a positioning slider 44 adapted to the positioning channel 26, and the positioning slider 44 can be preferentially disposed on the housing 41, such as... Figure 8 As shown, the positioning slider 44 and the positioning channel 26 cooperate to position and guide the installation process of the ball gate 4, ensuring that the ball gate 4 is always inserted into the second interface 25 in the preset position, so that there is no positional deviation during the insertion process, which is conducive to the strict alignment of the ball gate 4 and the guide cylinder 3.

[0051] During assembly, the upper end of the ball gate 4 can be inserted into the inner cavity 21 through the third interface 28, such as... Figure 11 and Figure 13 As shown, the upper end of the ball gate 4 can abut against the top of the inner cavity 21 (understandably, the upper end of the ball gate 4 needs to be constructed to fit the top of the inner cavity 21 for mutual cooperation), and the throwing channel 31 corresponds exactly to the ball outlet 42. In this embodiment, the throwing channel 31 and the ball outlet 42 are not only coaxial, but the sidewalls of the throwing channel 31 and the sidewalls of the ball outlet 42 also correspond one-to-one, achieving strict alignment. Figure 12 and Figure 13 As shown, on the one hand, during assembly, there is no need to manually adjust the installation angle of the guide cylinder 3 or the ball gate 4, making the assembly process simpler, more convenient, and more efficient. On the other hand, the shapes of the throwing channel 31 and the ball outlet 42 can be designed to better suit the shape of the glass-breaking ball 9. This not only helps prevent the glass-breaking ball 9 from rotating during its passage through the guide cylinder 3, making the throwing path of the glass-breaking ball 9 more accurate, but also effectively reduces friction and avoids collisions, thereby reducing the kinetic energy loss of the glass-breaking ball 9 and enabling it to be thrown farther, achieving a better glass-breaking effect.

[0052] like Figure 12 and Figure 13 As shown, the rear end of the guide cylinder 3 can directly abut against the side of the ball gate 4. Since they are in a perpendicular position, there will be no interference between them, and the gap between the throwing channel 31 and the ball outlet 42 can be minimized. Figure 13As shown, the rear end of the guide tube 3 is designed to fit the outer contour of the ball gate 4, which can reduce the resistance to the glass ball 9, prevent the glass ball 9 from colliding and getting stuck, and facilitate the smoother throwing of the glass ball 9.

[0053] In this embodiment, the ball gate 4 is detachably installed on the housing 2. It has multiple implementation methods. In one implementation method, the ball gate 4 can be detachably installed on the housing 2 by fasteners. For example, after the ball gate 4 is inserted into place, the ball gate 4 can be horizontally locked by the top bolts threaded to the housing 2 to achieve the purpose of fixing the ball gate 4.

[0054] In another embodiment, the second interface 25 is further provided with a snap-fit ​​structure adapted to the positioning slider 44. The snap-fit ​​structure locks and unlocks the positioning slider 44. That is, the positioning slider 44 not only cooperates with the positioning channel 26 to perform positioning and guiding functions, but also cooperates with the snap-fit ​​structure to lock and unlock the positioning slider 44, thereby achieving the purpose of quickly locking and unlocking the ball gate 4. Furthermore, it simplifies the structure and reduces costs. In implementation, the snap-fit ​​structure has various implementation methods and can be implemented using existing technology. In this embodiment, such as... Figures 2-4 and Figure 11 and Figure 13 As shown, the snap-fit ​​structure includes a spring 7, a locking rod 5, a cover component 6, and a mounting hole 27 constructed in the second interface 25. The mounting hole 27 is perpendicular to and communicates with the positioning channel 26. Figure 11 As shown; correspondingly, the locking rod 5 is constructed with a limiting step 51, and a locking block 52 is constructed on one side of the locking rod 5. A guide surface 53 is constructed on one side of the locking block 52, and the side opposite to the guide surface 53 is a limiting surface 54. The limiting surface 54 can be constructed as a vertical plane to limit the positioning slider 44, such as... Figure 11 As shown; during assembly, the lower end of the locking rod 5 is positioned within the assembly hole 27, and the spring 7 is positioned at the bottom of the assembly hole 27 and supports the locking rod 5, as shown. Figure 11 As shown; the cover component 6 has an opening 61, the cover component 6 is fixed to the housing 2, the limiting step 51 of the locking rod 5 abuts against the cover component 6 so as to use the cover component 6 to press the locking rod 5, the upper end of the locking rod 5 extends out of the cover component 6 through the opening 61, as shown. Figure 3 As shown, on the one hand, the locking block 52 can maintain the state of limiting and constraining the positioning slider 44, thereby keeping the ball gate 4 in a stable locked state; on the other hand, the locking rod 5 can move downward under the action of external force, causing the locking block 52 to leave the positioning channel 26, thereby releasing the limiting and constraining of the positioning slider 44, so as to quickly unlock the ball gate 4 and facilitate replacement; initially, the guide surface 53 corresponds to the positioning channel 26, and the guide surface 53 faces the outside of the second interface 25, as shown. Figure 3As shown, during the process of inserting the ball gate 4 into the second interface 25, the positioning slider 44 can be used to press the guide surface 53, and the guide surface 53 drives the locking rod 5 to move downward and compress the spring 7, so that the positioning slider 44 can pass smoothly through the locking block 52, and the locking block 52 can automatically reset after the positioning slider 44 passes, so as to lock the positioning slider 44, thereby achieving the purpose of quickly locking the ball gate 4.

[0055] In a more refined embodiment, the cover component 6 is also provided with a through hole 62, such as... Figure 2 and Figure 3 As shown, the second interface 25 has a threaded hole 35 on its side, so that the cover component 6 can be threadedly connected to the housing 2 by fasteners such as bolts or screws that fit the through hole 62 and the threaded hole 35, so as to install and remove the cover component 6.

[0056] In this embodiment, the valve core assembly is installed in the inner cavity 21, and the front end of the valve core assembly corresponds to the vent 43, as shown in the figure. In this embodiment, the housing 2 also has a third interface 28, which communicates with the inner cavity 21. The first interface 22 and the third interface 28 are located at opposite ends of the inner cavity 21, and the first interface 22 and the third interface 28 are coaxial, as shown in the figure. Figures 2-4 As shown, this is to allow the valve core assembly to be installed via the third interface 28. In implementation, the valve core assembly can be implemented using existing technology. For example, the valve core assembly includes a gas storage component 82 and a sealing mechanism 81 movably disposed on the gas storage component 82, such as... Figure 12 and Figure 13 As shown, the gas storage component 82 at the rear end of the valve core assembly is provided with a connector 83 for connecting a gas cylinder. In implementation, the gas cylinder sleeve can be threaded to the third interface 28. The gas cylinder sleeve has a receiving cavity for accommodating the gas cylinder. When the gas cylinder sleeve is threaded to the third interface 28, the connector 83 is connected to the receiving cavity. When a gas cylinder is placed in the receiving cavity, the connector 83 is connected to the gas cylinder, and the gas cylinder sleeve presses the gas cylinder against the connector 83 through the threaded connection to the third interface 28, so that the gas storage component 82 in the valve core assembly is in a state of communication with the gas cylinder.

[0057] Of course, in a more complete implementation, the launching body 1 also includes a locking mechanism adapted to the blocking mechanism 81 in the valve core assembly, a control module for controlling the locking mechanism, etc. For details, please refer to Chinese patent CN211893653U, which will not be elaborated here.

[0058] 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.
