Description

Technical Field

[0001] This application relates to the field of firecracker firing device technology, specifically to a grenade launcher model for firing firecrackers. Background Technology

[0002] Existing grenade launcher models typically possess only ornamental and collectible value. Their structural design is limited to static display needs, resulting in simple constructions lacking components for adjusting the barrel angle or adapting to firecracker firing. This severely restricts the functional application of grenade launcher models, failing to meet consumers' demands for more engaging and diverse functional experiences.

[0003] On the other hand, in traditional firecracker-setting scenarios, people usually light the firecrackers by hand and then throw them, or place them on the ground to light them. This conventional method of setting off firecrackers poses many safety risks. For example, when lighting a firecracker by hand, it may explode prematurely due to various uncontrollable factors at the moment of ignition, causing direct injury to the user's hand. Utility Model Content

[0004] Therefore, this application provides a grenade launcher model for setting off firecrackers, in order to solve the shortcomings of the existing grenade launcher models in terms of their single function, as well as the technical problems of safety hazards in traditional firecracker setting methods.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A grenade launcher model for setting off firecrackers includes a lifting mechanism and a barrel assembly disposed on top of the lifting mechanism. The lifting mechanism includes a base, a lifting component, and a lifting plate. The fixed end of the lifting plate is rotatably connected to one end of the base, and the movable end of the lifting plate can be mounted on the base. The lifting component is disposed between the base and the lifting plate, and the lifting component is used to control the lifting and lowering of the movable end of the lifting plate.

[0007] The barrel assembly is connected to the lifting plate. The barrel assembly includes a barrel body. The muzzle end of the barrel body extends forward along the length direction of the lifting plate. The breech end of the barrel body is located near the fixed end of the lifting plate. A first lead hole is provided on the barrel wall of the barrel body near the breech end. An openable safety cover is provided on the breech end.

[0008] Optionally, the base includes a base plate, a front plate disposed at the front end of the base plate, a rear plate disposed at the rear end of the base plate, and a side plate disposed on the side of the base plate. The side plate is attached to the rear plate. The fixed end of the lifting plate is rotatably connected to the upper end of the rear plate, and the movable end of the lifting plate can be mounted on the front plate. The lifting component includes a lead screw with both ends rotatably disposed on the front plate and the rear plate, a slider threaded onto the lead screw, a lifting rod with both ends rotatably connected to the slider and the lifting plate, a first bevel gear coaxially disposed at one end of the lead screw near the rear plate, a hand crank rotatably disposed on the side plate, and a second bevel gear connected to one end of the hand crank and meshing with the first bevel gear. The hand crank is used to rotate the second bevel gear.

[0009] Optionally, the barrel assembly further includes an outer sleeve and a pneumatic telescopic rod. The outer sleeve is slidably sleeved on the outside of the barrel body. The outer sleeve is provided with a stroke hole and a second lead wire hole. The second lead wire hole is correspondingly provided with the first lead wire hole. The telescopic end of the pneumatic telescopic rod is connected to the outer wall of the barrel body through the stroke hole via a first connecting post. The end of the pneumatic telescopic rod away from the telescopic end is connected to the outer wall of the outer sleeve via a second connecting post.

[0010] Further optionally, the barrel assembly further includes a sliding cover, which is slidably disposed relative to the outer sleeve, and the sliding cover can be closed onto the second lead hole.

[0011] Optionally, the barrel assembly further includes an auxiliary barrel, which is disposed below the barrel body.

[0012] Optionally, the howitzer model also includes a support frame disposed below the lifting mechanism.

[0013] Further optionally, the support frame includes a support frame body and a first support body, the first support body being disposed below the support frame body, and the first support body being connected to the support frame body via a damping pivot.

[0014] Optionally, the support frame further includes a second support body, which is disposed below the support frame body and is connected to the support frame body via a threaded telescopic rod.

[0015] Alternatively, one end of the threaded telescopic rod is provided with a ball head, and the upper part of the second support body is provided with a spherical groove adapted to the ball head, wherein the ball head is movably installed in the spherical groove.

[0016] Optionally, the howitzer model also includes a protective plate, which is connected to the front end of the lifting mechanism, with the muzzle end located in front of the protective plate.

[0017] Compared with the prior art, this application has at least the following beneficial effects:

[0018] A grenade launcher model for setting off firecrackers mainly consists of a lifting mechanism and a barrel assembly. The lifting mechanism includes a base, a lifting component, and a lifting plate. The fixed end of the lifting plate is rotatably connected to the base, while the movable end can be mounted on the base. The lifting component controls the raising and lowering of the movable end, thereby supporting and adjusting the tilt height of the barrel assembly. The barrel assembly can adjust its angle with the lifting plate, which greatly improves operational flexibility and fun compared to traditional fixed-structure models. Simultaneously, the barrel assembly functions as a firecracker launcher; adjusting its angle through the lifting mechanism achieves the optimal ignition effect. A first fuse hole located on the barrel wall near the breech end rationally plans the path for the firecracker fuse. An openable safety cap at the breech end effectively blocks sparks and foreign objects during firecracker ignition. These structural designs prevent direct contact between the user and the firecrackers, significantly improving the safety factor when setting off firecrackers. In summary, this application changes the limitation of existing grenade launcher models being used only for viewing and collection, enabling the models to also have entertainment functions, greatly expanding their functional boundaries, meeting consumers' demand for diversified functions of grenade launcher models, and creating a new application for grenade launcher models to safely set off firecrackers.

[0029] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] The purpose of this invention is to provide a grenade launcher model for setting off firecrackers, so as to meet consumers' demand for diversified functions of grenade launcher models.

[0031] refer to Figures 1-7 As shown, this embodiment provides a grenade launcher model for setting off firecrackers, including a lifting mechanism 100 and a barrel assembly 200, with the barrel assembly 200 disposed on top of the lifting mechanism 100.

[0032] The lifting mechanism 100 includes a base 110, a lifting component 120, and a lifting plate 130. The lifting plate 130 has a fixed end and a movable end. The fixed end of the lifting plate 130 is rotatably connected to one end of the base 110, and the movable end of the lifting plate 130 can be mounted on the base 110. The lifting component 120 is disposed between the base 110 and the lifting plate 130, and is used to control the lifting and lowering of the movable end of the lifting plate 130, so that the barrel assembly 200 can adjust its angle according to the lifting and lowering of the movable end of the lifting plate 130. Compared with the traditional fixed structure model, this greatly improves the operational flexibility and fun.

[0033] The cannon barrel assembly 200 is connected to the lifting plate 130. The cannon barrel assembly 200 includes a cannon barrel body 210. The muzzle end of the cannon barrel body 210 extends forward along the length of the lifting plate 130. The breech end of the cannon barrel body 210 is located near the fixed end of the lifting plate 130. A first lead hole is provided on the barrel wall of the cannon barrel body 210 near the breech end. An openable safety cover 212 is provided on the breech end. The first lead hole rationally plans the arrangement path of the firecracker lead. The safety cover 212 at the breech end can effectively block sparks and foreign objects when the firecracker is lit. These structural designs prevent users from directly contacting the firecracker, thereby significantly improving the safety factor of setting off firecrackers.

[0034] This application changes the limitation of existing grenade launcher models being used only for viewing and collection, enabling the models to also have entertainment functions, greatly expanding their functional boundaries, meeting consumers' demand for diversified functions of grenade launcher models, and creating a new application where grenade launcher models can safely set off firecrackers.

[0035] In a preferred embodiment, refer to Figure 3 , Figure 4As shown, the base 110 includes a base plate 111, a front plate 112, a rear plate 113, and a side plate 114. The front plate 112 is located at the front end of the base plate 111, the rear plate 113 is located at the rear end of the base plate 111, and the side plate 114 is located on the side of the base plate 111, with the side plate 114 attached to the rear plate 113. It should be noted that when the barrel body 210 is parallel to the base plate, the muzzle end faces forward. The fixed end of the lifting plate 130 is rotatably connected to the upper end of the rear plate 113, and the movable end of the lifting plate 130 can be mounted on the front plate 112. The lifting component 120 includes a lead screw 121, a slider 122, a lifting rod 123, a first bevel gear 124, a hand crank 125, and a second bevel gear 126. The two ends of the lead screw 121 are rotatably mounted on the front plate 112 and the rear plate 113, respectively. The lead screw 121 is preferably connected to the front plate 112 and the rear plate 113 by bearings. The slider 122 is threaded onto the lead screw 121. The two ends of the lifting rod 123 are rotatably connected to the slider 122 and the lifting plate 130, respectively. For example, the slider 122 is rectangular. Preferably, a mounting block of the same size as the slider 122 is provided on the bottom side of the lifting plate 130 near the fixed end. Two lifting rods 123 can be provided and symmetrically installed on both sides of the slider 122 and the mounting block. The first bevel gear 124 is coaxially mounted on the end of the lead screw 121 near the rear plate 113. A hand crank 125 is mounted on the side plate 114. The second bevel gear 126 is connected to one end of the hand crank 125 and meshes with the first bevel gear 124. The hand crank 125 is used to rotate the second bevel gear 126. The hand crank 125 includes a handle and a connecting rod. The handle is located on the outside of the side plate 114. One end of the connecting rod is connected to the handle, and the other end passes through the side plate 114 and connects to the second bevel gear 126. The connecting rod is fixed to the side plate 114 by a bearing.

[0036] By rotating the hand crank 125, the second bevel gear 126 is driven to rotate, which in turn drives the first bevel gear 124 to rotate, thereby driving the lead screw 121 to rotate. The rotation of the lead screw 121 causes the slider 122 to move on the lead screw 121. The movement of the slider 122 drives the lifting rod 123 to rise and fall, thereby raising and lowering the movable end of the lifting plate 130. In this way, the angle of the barrel assembly 200 can be adjusted more flexibly through this lifting mechanism 100.

[0037] The angle between the lifting plate 130 and the base plate 111 is in the range of 15°-90°. When the movable end of the lifting plate 130 is mounted on the front plate 112, the angle between the lifting plate 130 and the base plate 111 is 15°. That is, the minimum angle between the lifting plate 130 and the base plate 111 is limited by the height of the front plate 112.

[0038] refer to Figure 1 , Figure 2As shown, the cannon barrel assembly 200 includes an outer sleeve 220 and a pneumatic telescopic rod 270. The outer sleeve 220 is slidably sleeved on the outside of the cannon barrel body 210. The outer sleeve 220 is provided with a stroke hole 221 and a second lead hole 222, which corresponds to the first lead hole. The telescopic end of the pneumatic telescopic rod 270 is connected to the outer wall of the cannon barrel body 210 through the stroke hole 221 via a first connecting post 230. The end of the pneumatic telescopic rod 270 away from the telescopic end is connected to the outer wall of the outer sleeve 220 via a second connecting post 240. Preferably, two pneumatic telescopic rods 270 are provided, symmetrically arranged on both sides of the outer sleeve 220, and the outer sleeve 220 is relatively fixed to the lifting plate 130. When setting off firecrackers, the pneumatic telescopic rod 270 can buffer the backward force. It should be noted that the firecrackers set off in the cannon barrel body are usually double-bang firecrackers or other firecrackers with secondary explosions.

[0039] The barrel body 210 has a baffle 211 extending radially outward from the breech end of the barrel body 210. One end of the outer sleeve 220 abuts against the baffle 211, and the end of the stroke hole 221 away from the baffle 211 abuts against the first connecting post 230, thereby limiting the forward and backward movement range of the barrel body 210.

[0040] refer to Figure 5 As shown, preferably, the safety cover 212 is installed on the side of the baffle 211 away from the outer sleeve 220. The safety cover 212 is rotatably connected to one end of the baffle 211 by a first screw, and a second screw is provided at the other end of the baffle 211. The safety cover 212 is provided with a groove that matches the second screw. When the safety cover 212 is closed, it covers the opening at the breech end of the firecracker, and the groove engages with the second screw. This improves the safety when setting off firecrackers.

[0041] In a preferred embodiment, the barrel assembly 200 further includes a sliding cover 250, which is slidably disposed relative to the outer sleeve 220, and the sliding cover 250 can cover the second lead hole 222. Specifically, a slide rod 251 is fixedly disposed on the outer sleeve 220, and the sliding cover 250 is slidably sleeved on the slide rod 251, allowing the sliding cover 250 to move back and forth on the slide rod 251. (Reference) Figure 1 As shown, the first and second fuse holes 222 are positioned opposite each other and covered by the sliding cover 250. When setting off the firecrackers, the sliding cover 250 is moved to expose the fuse holes, and the fuse of the firecracker is placed outside the fuse holes. After the fuse is lit, the sliding cover 250 is quickly covered to prevent sparks and mud from leaking out when the firecrackers are set off, thereby further improving the safety of setting off firecrackers.

[0042] The gun barrel assembly 200 also includes an auxiliary gun barrel 260, which is located below the gun barrel body 210. Specifically, the lower side of the auxiliary gun barrel 260 is welded and fixed to the upper side of the lifting plate 130, and the upper side of the auxiliary gun barrel 260 is welded to the lower side of the outer sleeve 220. One or more auxiliary gun barrels 260 can be provided. The rear end of the auxiliary gun barrel 260 is sealed, and the front muzzle can be used to fire rockets, further improving the versatility of the howitzer model.

[0043] In a preferred embodiment, refer to Figure 2 As shown, the howitzer model also includes a support frame, which is located below the lifting mechanism 100. The support frame includes a support frame body 300 with wheels for supporting and facilitating the movement of the lifting mechanism 100 and the barrel assembly 200.

[0044] A first support body 310 can be set on the support frame body 300. The first support body 310 is located below the support frame body 300. The first support body 310 is connected to the support frame body 300 through a damping pivot 311. The separation angle of the first support body 310 can be easily adjusted, which helps to stabilize the grenade launcher model when setting off firecrackers.

[0045] A second support 320 can also be installed on the support frame body 300, and the second support 320 is also located below the support frame body 300. The second support 320 is connected to the support frame body 300 via a threaded telescopic rod 321. When no firecrackers are set off, it is preferable to use the second support 320 to support the grenade launcher model. The height of the second support 320 can be adjusted by rotating the threaded telescopic rod 321. Preferably, refer to Figure 6 As shown, one end of the threaded telescopic rod 321 is provided with a ball head 322, and the upper part of the second support body 320 is provided with a spherical groove to accommodate the ball head 322, so that the ball head 322 is movably connected with the spherical groove of the second support body 320. In this way, the angle of the second support body 320 can be adjusted at will, and the second support body 320 can better support the support surface at any angle.

[0046] In another embodiment, reference Figure 7 As shown, the grenade launcher model also includes a protective plate 400, which is connected to the front end of the lifting mechanism 100. Specifically, the protective plate 400 can be fixedly connected to the front side of the front plate 112, with the muzzle end located in front of the protective plate 400, thereby further improving the safety when setting off firecrackers.

[0047] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
