Description

Technical Field

[0001] This utility model relates to the field of model water rocket technology, and specifically to a water rocket launcher that can be inflated laterally. Background Technology

[0002] Model water rocket launchers are becoming increasingly popular among primary and secondary school students and their parents, leading to a growing market. However, the production of assembly parts and bases for existing model water rocket launchers typically requires more than three sets of molds, each with significant costs. Furthermore, after the parts are formed, they need to be manually assembled to create a complete set for sale to consumers. Since some parts may have similar shapes but differ slightly from left to right, this can easily result in incorrect shipments, leading to a poor customer experience and high costs associated with returns and rework.

[0003] Moreover, traditional water rocket launchers typically use a bottom inflation method, which requires a large space to be reserved at the bottom of the launcher for inflation, making it inconvenient for the overall assembly of the launcher.

[0004] In addition, existing water rocket launchers, due to their fixed shape, cannot be stacked and are often packaged individually and sent to distributors or consumers, which takes up a lot of packaging, transportation and storage space and results in high transportation costs. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings of the prior art and provide a water rocket launcher that can be inflated laterally, solving the problems of inconvenient inflation operation, excessive molds required in the production of spare parts, high cost, large space occupation, and inconvenience in stacking of existing water rocket launchers.

[0006] The technical solution adopted by this utility model is as follows: a side-inflatable water rocket launcher, comprising an integrally formed launcher body, the launcher body having a hollow rocket body insertion tube, the bottom of which is formed with a radially protruding radial platform; the bottom outer wall of the portion of the rocket body insertion tube above the radial platform is formed with a sealing ring groove; a pair of vertical sidewalls are formed on both sides of the radial platform facing upwards, the top of each vertical sidewall having a widened portion, the two widened portions extending towards each other to form an extension connecting portion surrounding the rocket body insertion tube, and each of the two widened portions having a connection point for inserting the rocket body. A cylindrical through-hole perpendicular to the tube axis; the widened portion and its extended connecting portion are formed with a cylindrical mating interface that allows the arrow body bottle mouth and its flange to pass through. The axis of the cylindrical mating interface coincides with the axis of the arrow body insertion tube, that is, the arrow body insertion tube passes through the cylindrical mating interface, and the cylindrical mating interface intersects with the cylindrical through-holes on both sides, that is, a notch is formed inside the two cylindrical through-holes that communicates with the cylindrical mating interface; an inflation part is also formed protruding on one side of the radial platform, and an inflation channel communicating with the inside of the arrow body insertion tube is formed inside the inflation part and the radial platform. A one-way inflation valve is installed at the port of the inflation part.

[0007] Furthermore, the transmitter also includes a transmitter base, which has a base main board. A first connecting platform with an upward protrusion is formed on the base main board. A pair of spaced-apart first pivot seats are formed at the upper end of the first connecting platform. A pair of coaxial first pivot holes are provided on the first pivot seats. Correspondingly, a first pivot part is also formed below the radial platform of the transmitter body. The first pivot part and the two first pivot seats are connected in an adjustable locking manner by a screw and nut.

[0008] Three hollow sections are formed on the base mainboard, two of which are L-shaped hollow sections facing each other, and the other is a first hollow section located between the two L-shaped hollow sections. A locking release component is formed in the first hollow section, and the locking release component is connected to the inner wall of the first hollow section through a first connecting rib. A first insert and a second insert in the shape of an L are formed in the two L-shaped hollow sections respectively, and the first insert and the second insert are connected to the inner wall of the L-shaped hollow section through a second connecting rib respectively. The first insert and the second insert each have a cylindrical insert body corresponding to the cylindrical through hole on the transmitter body, and the cylindrical insert body is formed with a cut recess opposite to the notch.

[0009] The latch release component has an "L"-shaped sheet body, and the long side of the "L"-shaped sheet body is provided with a second pivot seat on both sides; one end of the radial platform extends outward and is formed with a second pivot hole perpendicular to the axis of the arrow body insertion tube; when the latch release component is removed from the base main board, it is rotatably pivoted with the second pivot seat and the second pivot hole by screws and nuts, and the short side of the "L"-shaped sheet body faces upward and can abut against the side of the extended connection part.

[0010] The first and second inserts have elastic buckles at the front end of their cylindrical insert bodies. When inserted into the cylindrical through hole, the elastic buckles can retract to reduce their volume. After passing through the other end of the cylindrical through hole, the elastic buckles open, thus confining the first and second inserts within the cylindrical through hole. When disassembly is required, the elastic buckles can be pinched to shrink them, allowing the inserts to be pulled out. An arc-shaped limiting block is also formed at the root of the cylindrical insert bodies of the first and second inserts. Correspondingly, a limiting protrusion is also formed on the inner wall of the end of the cylindrical through hole.

[0011] The base main board also has a second hollow section formed therein, and a rectangular pin is formed therein. The rectangular pin is connected to the inner wall of the second hollow section through a third connecting rib. Correspondingly, a pin slot is provided in the middle of the short side of the first insert and the second insert, and in the locked state, the pin slots on the first insert and the second insert are on the same straight line, and the rectangular pin can be inserted into the pin slot.

[0012] On the radial platform, on the side opposite to the locking release component, a rubber band groove is also formed. The "L"-shaped sheet body of the locking release component also has rubber band grooves on both sides. The outside of the "L"-shaped sheet body is also provided with wiring holes for connecting pull wires. That is, the locking release component maintains the locking state by keeping elastic between the rubber band and the transmitter body. When releasing, the locking release component can be pulled open by overcoming the elastic force of the rubber band.

[0013] A wire hole is formed below the radial platform of the transmitter body and at the upper root of the first pivot part. A pull wire connection hole is provided at the lower end of the latch release component. A brake pull wire can be threaded through the wire hole. The end of the pull wire is connected to the pull wire connection hole of the latch release component. The brake pull wire can be used to pull the latch release component to realize the launch control action.

[0014] A second connecting platform with upward protrusion is formed at one of the opposite edges of the base main board. A "U"-shaped slot is formed at both ends of the second connecting platform. A pair of longitudinal grooves are also provided on the inner wall of the "U"-shaped slot. The interior of the first connecting platform and the second connecting platform are hollow and gradually narrow from bottom to top.

[0015] Positioning teeth are formed on the bottom outer wall of the first pivot part. Correspondingly, positioning strips corresponding to the positioning teeth are provided between the first pivot seats of the first connecting platform. The first pivot hole on the first connecting platform is a longitudinally adjustable strip hole, and an angle scale line is also provided on the outer end face of the first pivot seat where the first pivot hole is located. Correspondingly, the lower end of the side of the radial platform is obtuse-angled relative to the angle scale line.

[0016] The base main board is also provided with two recesses arranged vertically; the lower inner surface of the base main board is also formed with reinforcing ribs; the base main board is also formed with several connecting through holes; a slot is also provided in the middle of the second connecting platform on one side; and limiting support flanges are respectively formed on the outer corner sidewalls of the second connecting platform.

[0017] The present invention, through the above-described structure, has the following advantages:

[0018] Firstly, the launcher body is integrated with a side-mounted inflation section and a built-in inflation channel, allowing for side inflation with ample operating space, making it more convenient and overcoming the shortcomings of traditional bottom inflation, such as insufficient space and inconvenient operation. At the same time, it provides ample space and simplifies the design of the launcher base, which also facilitates assembly.

[0019] Secondly, when the transmitter base is integrally molded, three other transmitter components, namely the first insert, the second insert, and the locking release component, can be molded simultaneously. This reduces the number of molds required for the entire transmitter production, which can be achieved with only two sets of molds, significantly reducing production costs without affecting the support and stability of the base.

[0020] Third, the transmitter parts and base can be stacked, reducing space occupation and lowering packaging and transportation costs; the transmitter parts and base are packaged as a whole, which can avoid errors caused by manual repackaging of parts, avoid the risk of returns, and enhance the user's DIY fun.

[0021] Fourth, the locking release mechanism offers multiple release methods, allowing users to choose the method that best suits their needs, facilitating launch operations;

[0022] Fifth, the launcher base can be used with a water-filled mineral water bottle or an aluminum alloy track, which can greatly enhance the stability and adjustability of the launcher base during launch. Attached Figure Description

[0028] like Figures 1-3 As shown, this utility model describes a side-inflatable water rocket launcher, which includes an integrally formed launcher body 1. The launcher body 1 has a hollow rocket body insertion tube 11, and the bottom of the rocket body insertion tube 11 has a radially protruding radial platform 12. The bottom outer wall of the portion of the rocket body insertion tube 11 above the radial platform 12 has a sealing ring groove 111 and a sealing ring is installed thereon to achieve a sealed connection with the inner wall of the water rocket body nozzle, maintaining a seal before launch. The radial platform 12 has a pair of vertical sidewalls 121 formed on both sides facing upwards. The top of each vertical sidewall 121 has a widened portion 122. The two widened portions 122 extend towards each other to form an extension connecting portion 123 surrounding the arrow body insertion tube 11. Each of the two widened portions 122 has a cylindrical through hole 124 perpendicular to the axial direction of the arrow body insertion tube 11. The widened portions 122 and their extension connecting portions 123 have cylindrical openings that allow the arrow body nozzle and its flange to pass through. The cylindrical interface 101 has its axis coincident with the axis of the arrow body insertion tube 11, meaning the arrow body insertion tube 11 passes through the cylindrical interface 101. The cylindrical interface 101 intersects with the cylindrical through holes 124 on both sides, forming notches 125 inside the two cylindrical through holes 124 that communicate with the cylindrical interface 101. An inflation part 126 protrudes from one side of the radial platform 12. The inflation part 126 and the radial platform 12 contain an insertion tube that connects to the arrow body insertion tube. The inflation channel 102 is connected to the inside of the connector 11. A one-way inflation valve (not shown in the figure, such as a valve core) is installed at the port of the inflation part 126. Through the side-protruding inflation part 126 and the one-way inflation valve, the inflation operation of the water rocket body can be carried out on the side of the launcher, which is more convenient and does not occupy the space at the bottom of the launcher. This allows the bottom of the launcher to be better utilized, which can be used to simplify the launcher base and optimize the overall structure and assembly efficiency of the launcher.

[0029] Combination Figures 4-5As shown, furthermore, the transmitter also includes a transmitter base, which has a base main board 2. A first connecting platform 21 protruding upward is formed on the base main board 2. A pair of spaced-apart first pivot seats 211 are formed at the upper end of the first connecting platform 21. A pair of coaxial first pivot holes 212 are provided on the first pivot seats 211. Correspondingly, a first pivot part 13 is also formed below the radial platform 12 of the transmitter body 1. The first pivot part 13 and the two first pivot seats 211 are connected in an adjustable locking manner by screws and nuts. Thus, the transmitter body 1 can be locked and installed on the transmitter base by screws and nuts.

[0030] Three hollow sections are formed on the base main board 2, two of which are L-shaped hollow sections 201 facing each other, and the other is a first hollow section 202 located between the two L-shaped hollow sections; a locking release component 3 is formed in the first hollow section 202, and the locking release component 3 is connected to the inner wall of the first hollow section 202 through the first connecting rib 203; an L-shaped first insert 41 and a second insert 42 are formed in the two L-shaped hollow sections 201 respectively, and the first insert 41 and the second insert 42 are connected to the inner wall of the L-shaped hollow section 201 respectively through the second connecting rib 204; the first insert 41 and the second insert 42 each have a cylindrical insert body 401 corresponding to the cylindrical through hole 124 on the transmitter body 1, and the cylindrical insert body 401 is formed with a cutting recess 402 opposite to the notch 125;

[0031] In this way, some assembly parts of the water rocket launcher, namely the first insert 41, the second insert 42, and the locking release component 3, can be molded with the base mainboard 2 using the same set of molds. This greatly reduces the number of molds used in the production of the water rocket launcher, thereby saving mold costs. In addition, these parts are made as a whole with the base, eliminating the need for manual assembly. They can be directly sent to consumers, who can cut them out and assemble them themselves. This prevents problems such as sending the wrong parts when manually assembling components, and also allows consumers to have a better DIY experience.

[0032] Combination Figure 6As shown, during assembly, the two cylindrical through holes 124 are used to install the first insert 41 and the second insert 42, respectively. Since the inserts also have cutting recesses 402 opposite to the notch 125, when the two inserts are rotated to the position of the cutting recesses 402 facing the radial platform 12, the inner edge of the cutting recesses 402 will protrude into the cylindrical mating interface 101, thereby locking the nozzle flange of the rocket body and keeping the rocket body in place. At this time, the exposed parts of the "L"-shaped first insert 41 and second insert 42 are also perpendicular to the axis of the rocket body insert tube. And it is locked by the short side locking part of the locking release part 3, at which time air can be injected into the water rocket; when released, the water rocket body impacts the cutting recess 402 of the insert bar upward under the action of internal pressure, so that the insert bar rotates to the point where the cutting recess 402 faces the insert tube 11 of the rocket body. The insert bar will not protrude into the cylindrical docking interface 101 because of the cutting recess 402, so it will not jam the bottle mouth of the rocket body, and the water rocket can be launched. At this time, the exposed parts of the first insert bar 41 and the second insert bar 42 of the "L" shape are also parallel to the axis of the insert tube 11 of the rocket body.

[0033] Specifically, the locking release component 3 has an "L"-shaped sheet-like body 31, with second pivot seats 32 on both sides of the long side of the "L"-shaped sheet-like body 31; one end of the radial platform 12 extends outward and forms a second pivot hole 127 perpendicular to the axial direction of the rocket body insertion tube 11; when the locking release component 3 is removed from the base main board 2, it forms a rotatable pivot connection with the second pivot seat 32 and the second pivot hole 127 using screws and nuts, and the short side of the "L"-shaped sheet-like body 31 faces upward and can abut against the side of the extended connection part 123. In the locking state, the short side holds the parts outside the main body of the first insertion strip 41 and the second insertion strip 42 inside the lower part of the short side to form a lock. When the locking release component 3 rotates, the short side rotates axially around the second pivot hole 127 and disengages from the first insertion strip 41 and the second insertion strip 42, so that the restriction of the two insertion strips disappears. Under the action of the internal pressure of the water rocket body, the bottle mouth flange breaks through the restriction of the two insertion strips and realizes the launch.

[0034] The cylindrical insert body 401 of the first insert 41 and the second insert 42 has an elastic buckle 403 formed at its front end insertion portion. When inserted into the cylindrical through hole 124, the elastic buckle 403 can retract to reduce its volume. After passing through the other end of the cylindrical through hole 124, the elastic buckle 403 opens, thereby confining the first insert 41 and the second insert 42 within the cylindrical through hole 124. When disassembly is required, the elastic buckle 403 can be pinched by hand to shrink it, and the insert can be pulled out. At the root of the cylindrical insert body 401 of the first insert 41 and the second insert 42, an arc-shaped limiting block 404 is formed. Correspondingly, a limiting protrusion 1241 is also formed on the inner wall of the end of the cylindrical through hole 124. Through the arc-shaped limiting block 404 and the limiting protrusion 1241, the rotation angle of the first insert 41 and the second insert 42 can be limited, avoiding unnecessary arbitrary rotation of the first insert 41 and the second insert 42, and also preventing the first insert 41 and the second insert 42 from being inserted into each other incorrectly.

[0035] The base main board 2 also has a second hollowed-out portion 205 formed therein, and a rectangular pin 43 is formed therein. The rectangular pin 43 is connected to the inner wall of the second hollowed-out portion 205 through a third connecting rib 206. Correspondingly, a pin slot 405 is provided in the middle of the short side of the first insert 41 and the second insert 42. When locked, the pin slots 405 on the first insert 41 and the second insert 42 are on the same straight line. The rectangular pin 43 can be inserted into the pin slot 405. In this way, the first insert 41 and the second insert 42 can be locked without the need for a locking release component. The rectangular pin 43 is used so that when there are multiple water rocket cluster launchers, the launch of the previous water rocket drives the pull line to open the rectangular pin of the next launcher, so that the next water rocket can be launched. In this way, cluster launches can be achieved one after another.

[0036] On the radial platform 12, on the side opposite to the locking release component 3, a rubber band groove 128 is also formed. The "L"-shaped sheet body 31 of the locking release component 3 is also provided with rubber band grooves 33 on both sides. The long side of the "L"-shaped sheet body 31 is also provided with a wiring hole 311 for connecting a pull wire. That is, the locking release component 3 maintains the locking state by keeping elastic between the rubber band and the transmitter body 1. When releasing, the locking release component 3 can be opened by connecting the pull wire to overcome the elasticity of the rubber band.

[0037] A wire hole 14 is formed below the radial platform 12 of the transmitter body 1 and at the upper root of the first pivot part 13. A pull wire connection hole 34 is provided at the lower end of the latch release component 3. A brake pull wire can be threaded through the wire hole 14. The end of the pull wire is connected to the pull wire connection hole 34 of the latch release component 3. The latch release component 3 can be pulled by the brake pull wire to realize the launch control action.

[0038] A positioning tooth 131 is formed on the bottom outer wall of the first pivot part 13. Correspondingly, a positioning strip 213 corresponding to the positioning tooth is provided between the first pivot seats 211 of the first connecting platform 21, so that the transmitter body and the base are fixed at a certain angle for launching. The first pivot hole 212 on the first connecting platform 21 is a longitudinally adjustable strip hole, and the outer end face of the first pivot seat 211 where the first pivot hole 212 is located is also provided with an angle scale line 2111. Correspondingly, the lower side of the radial platform 12 is an obtuse angle 12 opposite to the angle scale line 2111. The first pivot hole 212 is a longitudinally adjustable strip hole. Its function is to lift the transmitter body upward after loosening the bolts and nuts, so that the positioning teeth 131 at the bottom are disengaged from the positioning strip 213. In this way, the angle of the transmitter body 1 can be adjusted at will. Then, tightening the bolts and nuts will fix it. When the bolts and nuts are loosened, the transmitter body 1 rotates to the point where the obtuse angle 129 corresponds to the angle indicated by the angle scale line 2111. The transmitter body 1 can be pressed down to make the positioning teeth 131 and the positioning strip 213 lock. Then, the bolts and screws can be tightened. In this way, the launch angle can be adjusted by the positioning teeth 131 and the positioning strip 213, which is convenient for launching at several commonly used angles.

[0039] On a set of opposite edges of the base main board 2, there are two upward-protruding second connecting platforms 22. At both ends of the second connecting platforms 22, there are "U"-shaped slots 221. The inner wall of the "U"-shaped slots 221 is also provided with a pair of longitudinal grooves 222. The distance between the longitudinal grooves 222 is approximately equal to the diameter of the flange at the mouth of the mineral water bottle. The mouth of a mineral water bottle filled with water can be locked into the "U"-shaped slots 221 through the "U"-shaped slots 221 and the longitudinal grooves 222 on the inner wall, so that the mineral water bottle is connected to the base in a horizontal position. Four mineral water bottles filled with water can greatly increase the stability of the base. In the middle of one side of the second connecting platform 22, there is also a slot 223. The function of the slot 223 is to facilitate the passage of the water rocket blades when the water rocket is launched at a small angle.

[0040] Both the first connecting platform 21 and the second connecting platform 22 are hollow inside and gradually taper from bottom to top. This allows multiple base motherboards 2 to be stacked one on top of the other, thereby significantly reducing the space occupied by the packaging and saving packaging and transportation costs.

[0041] The base main board 2 also has two vertically arranged recesses 23 for mounting a small glass level, facilitating the inspection of the base's levelness and adjustment of position and angle during use. The lower inner surface of the base main board 2 is also formed with several sets of reinforcing ribs 24 to enhance the overall strength and stability of the main board. The positions of the reinforcing ribs 24 can be adjusted as needed. The reinforcing ribs 24 located inside the first connecting platform 21 also have a limiting function after stacking, preventing wobbling when the upper and lower bases are stacked, resulting in greater stability. The base main board 2 also has several connecting through holes 25, through which screws and aluminum alloy rails can be used for connection, assembly, and position adjustment, enabling simultaneous assembly and use of multiple transmitters in various ways, offering greater flexibility and convenience.

[0042] Limiting support flanges 224 are formed on the outer corner sidewalls of the second connecting platform 22. The function of the limiting support flanges 224 is to limit and support the products after they are stacked, so as to prevent the products from squeezing each other and bursting when they are stacked too much, and also to prevent the products from being stacked too tightly and making them difficult to remove.

[0043] The present invention, through the above-described structure, has the following advantages:

[0044] Firstly, the launcher body is integrated with a side-mounted inflation section and a built-in inflation channel, allowing for side inflation with ample operating space, making it more convenient and overcoming the shortcomings of traditional bottom inflation, such as insufficient space and inconvenient operation. At the same time, it provides ample space and simplifies the design of the launcher base, which also facilitates assembly.

[0045] Secondly, when the transmitter base is integrally molded, three other transmitter components, namely the first insert, the second insert, and the locking release component, can be molded simultaneously. This reduces the number of molds required for the entire transmitter production, which can be achieved with only two sets of molds, significantly reducing production costs without affecting the support and stability of the base.

[0046] Third, the transmitter parts and base can be stacked, reducing space occupation and lowering packaging and transportation costs; the transmitter parts and base are packaged as a whole, which can avoid errors caused by manual repackaging of parts, avoid the risk of returns, and enhance the user's DIY fun.

[0047] Fourth, the locking release mechanism offers multiple release methods, allowing users to choose the method that best suits their needs, facilitating launch operations;

[0048] Fifth, the launcher base can be used with a water-filled mineral water bottle or an aluminum alloy track, which can greatly enhance the stability and adjustability of the launcher base during launch.

[0049] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
