Description

Technical fields:

[0001] This invention belongs to the field of water rocket technology, specifically referring to a claw-type launcher for launching water rockets and its launching method. Background technology:

[0002] Existing water rocket (air rocket) launchers typically use a quick-connect mechanism, employing ball bearings and springs to lock and position the water rocket. Launch is achieved by pulling down the movable outer ring of the quick-connector, usually via a connecting cable. This cable-pulling method suffers from drawbacks such as uneven tension and uneven movement of the movable outer ring, resulting in unsmooth water rocket launches. Furthermore, existing water rocket launchers have a relatively short launch distance, generally only about two meters at most. Users are easily splashed with water during launch, causing inconvenience. Typically, one person can only control the launch of one water rocket at a time, making it impossible to launch multiple rockets simultaneously or in coordinated bursts.

[0003] The applicant has also developed several other types of transmitters, but they are more complex in structure and have more parts, making them more inconvenient to assemble and requiring specific tools. This is not very convenient for consumers, and for manufacturers and sellers, in addition to the troublesome packaging of the product itself, they also need to provide buyers with various tools, resulting in higher overall costs.

[0004] The inventor has also developed a claw-type launcher, such as the claw-type launcher for water rockets disclosed in the patent number. It solves the problems of numerous and scattered launcher parts to a certain extent. However, it has problems such as the limit frame or limit strip being easy to fall off or break, which brings inconvenience to the use of water rockets. Moreover, the limit frame has a long travel distance during release and is prone to deviation during the movement, which leads to asynchronous release of the two claws and affects the launch effect. Summary of the Invention:

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings of existing products and to provide a claw-type launcher for water rocket launch and its launch method.

[0006] The technical solution adopted in this invention is: a claw-type launcher for launching water rockets, comprising an integrally formed launcher body with a hollow longitudinal guide tube. A pair of opposing first radial mounting seats are radially formed on the bottom outer wall of the longitudinal guide tube. A claw is pivotally mounted on each first radial mounting seat via a pivot shaft. Each claw has a latching portion protruding towards the center of the longitudinal guide tube at its upper end. Limiting crossbars facing each other are formed on the same side of the two latching portions, with one limiting crossbar located on the outer side and the other on the inner side. The launcher also includes a limiting mechanism for restricting and releasing the two limiting crossbars. When the limiting mechanism restricts the limiting crossbars, the claws and latching portions cannot move; when the limiting mechanism releases the limiting crossbars, the limiting crossbars, claws, and their latching portions can open and move.

[0007] In a first embodiment of the present invention, the limiting mechanism is a rotatable latch body, one end of which is detachably and rotatably pivotally connected to a second radial mounting seat formed on the bottom outer wall of the longitudinal guide tube; the other end of the latch body is formed with a latch portion, which can abut against the top surface of the two limiting crossbars to restrict the upward movement of the limiting crossbars.

[0008] In the above embodiment, a frame-shaped through hole protrudes from the inner wall of the buckle body; hook portions are respectively provided on the inner walls of the two claws, an elastic band passes through the frame-shaped through hole and its two ends are respectively connected to the hook portions on the claws; a rope hole for connecting a pull rope is provided outside the buckle portion of the buckle body.

[0009] As a second embodiment of the present invention, the limiting mechanism includes a limiting pin and pin slots disposed on two limiting crossbars that can simultaneously cooperate with the limiting pin; when the top surfaces of the two limiting crossbars are flush, the two pin slots are on the same straight line, and at this time the limiting pin can pass through the two pin slots at the same time.

[0010] Furthermore, the radial cross-section of the limiting pin is rectangular, and correspondingly, the cross-section of the pin groove is also rectangular; a slot for placing the limiting pin is provided on the transmitter body; and a wire hole for connecting the pull wire is provided at the outer end of the limiting pin.

[0011] A slot for placing a limiting pin is provided on the side of the frame-shaped through hole on the inner wall of the buckle body, and a protruding inclined surface is provided on the inner bottom surface of the slot; limiting arms that can contact the outer wall of the claw to further limit the claw are also provided on both sides of the buckle body.

[0012] The present invention also provides a launching method for the launcher of the second embodiment described above. The launching method is as follows: a launching method for a claw-type launcher for water rockets, comprising: setting up and assembling at least two water rocket bodies and at least two claw-type launchers; wherein, a limiting pin in the first claw-type launcher is connected to a pull wire through a wire hole; a limiting pin in the second claw-type launcher is connected to the water rocket body mounted on the first claw-type launcher through another pull wire, and so on, with the limiting pin of each subsequent claw-type launcher connected to the preceding water rocket body through a pull wire, forming a series connection; the limiting pin of the first claw-type launcher is pulled by hand to dislodge it, thereby removing the limiting mechanism and allowing the first water rocket body to separate from the launcher and be launched; after the first water rocket body is launched, the limiting pin on the subsequent claw-type launcher is pulled by the pull wire to disengage it from the pin slot, thereby launching the subsequent water rocket body; and so on, enabling multiple water rocket bodies to form a series-linked, relay-style launch (cluster relay launch).

[0013] Furthermore, in the second embodiment, the outer end of the limiting pin has a downwardly extending extension section, and when the limiting pin and the pin groove are assembled and engaged in the state of limiting the horizontal bar, the end of the extension section protrudes beyond the bottom air inlet of the transmitter, that is, the bottom of the extension section is lower than the bottom air inlet of the transmitter.

[0014] The present invention also provides a launching method for the above-mentioned claw-type launcher for launching water rockets. The launching method is as follows: First, water is injected into the water rocket body. Then, the longitudinal guide tube of the launcher is inserted into the water rocket body and inverted. The latching part of the launcher's claw engages with the flange at the bottle mouth of the water rocket body. The limiting pin is inserted into the pin groove of the two limiting crossbars, with the extension of the limiting pin facing downwards and below the bottom air inlet. Then, air is injected into the water rocket body through the air inlet at the bottom of the launcher to form a certain air pressure. After inflation is completed, the air inlet is disconnected from the external inflation tube. During launch, the water rocket body is held in hand with the air inlet of the launcher facing downwards. The water rocket body is released directly, allowing the body and launcher to fall freely. The bottom end of the extension of the inverted "L"-shaped limiting pin collides with the ground, causing the limiting pin to separate from the pin groove, thus removing the limiting mechanism and allowing the water rocket body to separate from the launcher and be launched.

[0015] The method also includes: setting up a cylindrical launch tube with an open top and a closed bottom (or using the ground to form a closed section), dropping the inflated water rocket body and launcher into the launch tube from the top opening, and the bottom end of the extension of the inverted "L"-shaped limiting pin colliding with the bottom of the launch tube, thereby separating the limiting pin from the pin groove, causing the limiting mechanism to lose its limiting function, and the water rocket body can then separate from the launcher and be launched along the launch tube, forming a launch effect similar to that of a mortar.

[0016] The angle of the launch tube is adjustable.

[0017] With the above-mentioned structure, the present invention utilizes the limiting horizontal bar extending from the gripper for limiting locking and releasing, which can shorten the release stroke of the limiting mechanism and improve the release synchronization, making it easier to launch; the limiting mechanism has a diversified structure, which can realize a variety of launch methods, such as multiple water rocket cluster launches or relay launches, mortar-style launches, etc., bringing different launch effects and meeting the needs of more users.

[0023] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0024] First, such as Figures 1-2As shown, the present invention discloses a claw-type launcher for launching water rockets, which has an integrally formed launcher body 1. The launcher body has a hollow longitudinal guide tube 11, which is arranged upwards. The bottom of the launcher body 1 is provided with an air inlet communicating with the longitudinal guide tube 11. A pair of opposing first radial mounting seats 12 are radially formed on both sides of the bottom outer wall of the longitudinal guide tube 11. A claw 2 is pivotally mounted on each first radial mounting seat 12 via a pivot shaft. The upper end of each claw 2 protrudes towards the center of the longitudinal guide tube 11. The transmitter includes a latching part 21; at the ends of the two latching parts 21 on the same side, there are limiting bars 22 facing each other, one of the limiting bars 22 is located on the outside and the other is located on the inside, and the top surfaces of the two limiting bars 22 are flush; the transmitter also includes a limiting mechanism 3 that can limit and release the two limiting bars 22. When the limiting mechanism 3 limits the limiting bars 22, the gripper 2 and the latching part 21 cannot move; when the limiting mechanism 3 releases the limiting bars 22, the limiting bars 22, the gripper 2 and the latching part 21 can be opened and moved around their pivot axes respectively.

[0025] In a first embodiment of the present invention, the limiting mechanism 3 is a rotatable latch body 31. One end of the latch body 31 is detachably and rotatably pivotally connected to a second radial mounting seat 13 formed on the bottom outer wall of the longitudinal guide tube 11. For example, the latch body 31 and the second radial mounting seat 13 can be detachably and rotatably connected by a long bolt (not shown in the figure). The other end of the latch body 31 is formed with a latch portion 311, and the latch portion 311 can abut against the top surface of the two limiting crossbars 22 to restrict the upward movement of the limiting crossbars 22. At this time, the gripper claw... 2 and its latch 21 and limiting crossbar 22 are all restricted from opening, thus restricting the water rocket to the launcher; when the latch 311 is rotated outward around the pivot of the second radial mounting seat 13 under the action of an external force (such as pulling the latch 31 by a rope), the two limiting crossbars 22 are released, the two limiting crossbars 22 and the latch 21 of the claw 2 lose the restrictive force, the claw 2 is in an openable state, and under the action of the internal pressure of the water rocket, it will fly upward along the longitudinal guide tube 11, break through the restriction of the claw 2 and be launched.

[0026] Combination Figure 3As shown in the above embodiment, a frame-shaped through hole 312 protrudes from the inner wall of the latch body 31; hook portions 201 are respectively provided on the inner walls of the two grippers 2; an elastic band 202 passes through the frame-shaped through hole 312 and its two ends are respectively connected to the hook portions 201 on the grippers 2, so that the latch portion 311 of the latch body 31 and the grippers 2 can be reset through the connection of the elastic band 202; under normal conditions, it is kept in contact with the top surface of the limiting crossbar 22, that is, the movement of the limiting crossbar is restricted under normal conditions; a rope hole 313 for connecting a pull rope is provided on the outside of the latch portion 311 of the latch body 31, so that the latch body can be pulled by pulling the rope to release the limiting crossbar 22 and launch the water rocket. When the latch body 31 is pulled by pulling the rope, the entire water rocket launcher is used by fixing it on the launch frame.

[0027] For example Figure 4 , Figure 5 As shown, in a second embodiment of the present invention, the limiting mechanism includes a limiting pin 32 and pin grooves 221 (or pin holes) disposed on two limiting crossbars 22 that can simultaneously engage with the limiting pin 32. When the top surfaces of the two limiting crossbars 22 are flush, the two pin grooves 221 are on the same straight line, and the limiting pin 32 can pass through both pin grooves 221 at the same time. When the water rocket is assembled and there is a certain pressure inside the rocket body, the flange at the bottle mouth of the water rocket body applies a reverse force to the latching part 21 of the gripper 2, causing the gripper 2 to tend to open. Since the limiting pin 32 is locked in the pin grooves 221 of the two limiting crossbars 22, it achieves the function of limiting the opening of the limiting crossbars 22 and the entire gripper 2, and the limiting pin 32 will not easily disengage from the pin grooves 221. Only when the limiting pin 32 disengages from the pin grooves 221 under the action of external force does the limiting structure lose its function, and the water rocket can be launched at this time.

[0028] Furthermore, the radial cross-section of the limiting pin 32 is rectangular, and correspondingly, the cross-section of the pin groove 221 is also rectangular. The large cross-sectional area on both sides of the rectangle makes the limiting and positioning more stable. A slot for placing the limiting pin 32 is provided on the transmitter body 1. That is, when the limiting pin 32 is not in use, it can be placed in the slot to avoid loss. For example, the slot can be set on the second radial mounting seat 13, or it can be placed using the frame-shaped through hole 312 inside the latch body 31.

[0029] The outer end of the limiting pin 32 is provided with a wire hole 321 for connecting a pull wire, which makes it easy to pull the limiting pin with a rope to release it. The length can be adjusted by the pull wire, which makes it easy to control the launch of the water rocket from a distance.

[0030] The present invention also provides a launching method for the launcher of the second embodiment described above. The launching method is as follows: At least two water rocket bodies and at least two claw-type launchers are respectively arranged and assembled. The limiting pin in the first claw-type launcher is connected to a pull wire through a wire hole. The limiting pin in the second claw-type launcher is connected to the water rocket body mounted on the first claw-type launcher through another pull wire, and so on. The limiting pin of each subsequent claw-type launcher is connected to the preceding water rocket body through a pull wire, forming a series connection. The limiting pin of the first claw-type launcher is pulled by hand, causing it to disengage and thus the limiting mechanism loses its restrictive function, allowing the first water rocket body to separate from the launcher and be launched. After the first water rocket body is launched, the limiting pin on the subsequent claw-type launcher is pulled by the pull wire, causing it to disengage from the pin slot, thus launching the subsequent water rocket body. This process is repeated, allowing multiple water rocket bodies to form a series-linked, relay-style launch (cluster relay launch).

[0031] like Figure 6 As shown, further, in the second embodiment, the outer end of the limiting pin 32 has a downwardly extending extension section 322, and when the limiting pin 32 and the pin groove 221 are assembled and engaged in the state of limiting the limiting crossbar 22, the end of the extension section 322 protrudes from the bottom air inlet 101 of the transmitter, that is, the bottom of the extension section 322 is lower than the bottom air inlet 101 of the transmitter.

[0032] Combination Figure 5 As shown, the present invention also provides a launching method for a claw-type launcher for launching water rockets. The launching method is as follows: First, water is injected into the water rocket body. Then, the longitudinal guide tube 11 of the launcher is inserted into the water rocket body and inverted. The latching part 21 of the launcher's claw 2 latches with the flange at the bottle mouth of the water rocket body. The limiting pin 32 is inserted into the pin groove of the two limiting crossbars 221. The extension section 322 of the limiting pin 32 faces downward and is lower than the bottom air inlet 101. Then, the launcher is launched... Air is injected into the water rocket body through the air inlet at the bottom of the device to form a certain air pressure; after inflation is completed, the air inlet is disconnected from the external air inlet pipe; when launching, hold the water rocket body with the air inlet of the launcher facing down and release the water rocket body directly, allowing the body and launcher to fall freely. The bottom end of the extension 322 of the inverted "L"-shaped limiting pin 32 collides with the ground, thereby separating the limiting pin 32 from the pin groove 221, causing the limiting mechanism to lose its limiting function, and the water rocket body can then separate from the launcher and be launched.

[0033] The method further includes: setting up a cylindrical launch tube (not shown in the figure) with an open top and a closed bottom; dropping the inflated water rocket body and launcher into the top opening of the launch tube; the bottom end of the extension of the inverted "L"-shaped limiting pin collides with the bottom of the launch tube, causing the limiting pin to separate from the pin groove, thus removing the limiting mechanism's restraining effect; the water rocket body can then separate from the launcher and be launched along the launch tube, creating a launch effect similar to a mortar firing. The angle of the launch tube is adjustable, allowing the launch angle to be adjusted as needed for better launch results.

[0034] For example Figure 7 As shown, in another embodiment of the latch body, a slot 314 is provided on the side of the frame-shaped through hole 312 on the inner wall of the latch body 31. The inner bottom surface of the slot 314 has a protruding inclined surface 315. The function of the slot 314 is to place the limiting pin 32. When the limiting pin 32 is not used, the limiting pin 32 is inserted into the slot 314 from the other side of the frame-shaped through hole 312. The protruding inclined surface 315 in the slot 314 causes one end of the limiting pin 32 to be raised, thereby making the limiting pin 32 tightly abut against the inner wall of the frame-shaped through hole 312 and fixing it in place. This makes it convenient for the user to find and place the limiting pin 32. On both sides of the latch body 31, there are also limiting curved arms 316 that can contact the outer wall of the claw 2 on the corresponding side to further limit the claw 2. As shown, they are L-shaped. The limiting curved arms 316 on both sides can further enhance the locking function of the claw 2, making the claw 2 more stable before launch.

[0035] With the above-mentioned structure, the present invention utilizes the limiting horizontal bar extending from the gripper for limiting locking and releasing, which can shorten the release stroke of the limiting mechanism and improve the release synchronization, making it easier to launch; the limiting mechanism has a diversified structure, which can realize a variety of launch methods, such as relay launch of multiple water rockets, mortar-style launch, etc., bringing different launch effects and meeting the needs of more users.
