Description

Technical Field

[0001] The utility model relates to the technical field of toys, in particular to a connecting device. Background Art

[0002] Fireworks and firecrackers refer to arts and crafts made from pyrotechnic powder as raw materials, which are entertainment products that burn (explode) after being ignited by a fire source and are accompanied by sound, light, color, smoke, fog and other effects; for example, rockets, double-bang cannons, etc.

[0003] Currently, most rockets are launched by placing them on the ground, igniting them with an igniter, and then moving away from the rocket after the fuse is lit. The rocket then shoots straight into the sky and explodes. During this process, only one rocket can be ignited at a time, and only one rocket can rise into the sky at a time, which is not very interesting. In addition, cities mainly have hardened roads and many obstructions. Existing rocket products are not convenient to insert into the ground and cannot be used in such an environment. Secondly, they are affected by environmental factors such as wind when launched, and are easily affected by the expected flight route and fall into buildings or crowds, thereby causing injuries.

In order to enable any technician in the field to implement and use the utility model, the following description is given. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the utility model can be implemented without using these specific details. In other examples, well-known structures and processes will not be elaborated in detail to avoid unnecessary details that make the description of the utility model obscure. Therefore, the utility model is not intended to be limited to the embodiments shown, but is consistent with the widest range of principles and features disclosed in the present application.

[0040] This embodiment provides a highly interesting and safe linkage device to solve the problem of unstable launch angle and trajectory of rocket products, and multiple rockets can be ignited and launched in sequence.

[0041] See also Figure 1 , Figure 2 , Figure 4The specific structure includes a loading piece 100, which is provided with a plurality of mounting holes 101 arranged side by side and spaced apart, and a fuse area 102 with an opening at the bottom, wherein the plurality of mounting holes 101 are opened along the length direction of the fuse area 102 and are connected thereto, so that after the product 300 to be ignited is arranged in the mounting hole 101, the fuse of the product 300 extends to the fuse area 102; preferably, the mounting hole 101 is funnel-shaped, and when the rocket is placed in the funnel-shaped mounting hole 101, the bottom of the rocket is located in the upper part of the funnel, perpendicular to the loading piece 100 and not tilted, and the fuse on the rocket is extended to the fuse area 102.

[0042] See also Figure 1 , Figure 3 , Figure 8 , a connecting piece 200, the connecting piece 200 is adapted to be sealed and connected to the bottom of the lead area 102, and is enclosed with the lead area 102 to form a plurality of connecting areas 201 arranged side by side at intervals, and the upper parts of the plurality of connecting areas 201 are connected, so that the products 300 loaded on the loading part 100 are ignited in turn in the plurality of connecting areas 201, that is, when the fuse of a rocket located at the edge of the loading part 100 is ignited, the fuse continues to burn to ignite the rocket, and at this time, thermal pressure and heat flow are generated in the connecting area 201 where the rocket is located to guide the flame of the rocket to the adjacent connecting area 201, thereby igniting the adjacent rockets, and then presenting the effect that igniting one rocket can ignite multiple rockets one by one and launch them, which greatly improves the fun of the rocket product 300. In addition, in this process, the rocket is vertically inserted into the mounting hole 101 and then launched, which avoids the instability of the rocket due to problems such as the ascent angle and trajectory, and further reduces the after-sales problems of the rocket manufacturer. Among them, a product 300 to be ignited (i.e., a rocket product 300) is placed in one of the mounting holes 101; the lead area 102 is a cavity structure with an opening at the bottom, which is connected with the connecting piece 200 to form a plurality of connecting areas 201 arranged side by side and spaced apart to achieve the above-mentioned purpose of igniting a plurality of rockets in sequence.

[0043] In the specific operation process, see Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 8 , Fig. 9 In order to facilitate the connection between the loading member 100 and the connecting member 200, two rows of insertion columns 103 are symmetrically arranged on the outer side wall of the loading member 100 along its width direction. In order to enhance stability, the front and rear sides of each mounting hole 101 (with Figure 1perspective as an example) an insertion column 103 is provided; at the same time, the outer wall of the connecting member 200 along the width direction thereof is symmetrically provided with two rows of sockets 202 adapted to be plugged with the insertion column 103, so that the bottom end of the insertion column 103 extends out of the loading member 100 and is inserted into the socket 202; further, a vertical plate 104 is symmetrically provided on the left and right sides of the loading member 100, and the vertical plate 104 is integrally formed with the loading member 100, and the height of the vertical plate 104 is equal to the sum of the height of the loading member 100 plus the height of the connecting member 200, so that the side walls on the left and right sides of the connecting member 200 are respectively abutted against the inner walls of the vertical plate 104 on the corresponding sides, further strengthening the connection stability between the loading member 100 and the connecting member 200. In order to enhance the connection stability between the connecting member 200 and the loading member 100, each of the two rows of insertion columns 103 is provided with an insertion column with a large diameter, and is respectively located at the left and right ends of the loading member 100; similarly, the connecting member 200 is provided with a socket of a size adapted thereto.

[0044] In the specific implementation process, see Figure 1-Figure 7 The loading part 100 is also provided with a sleeve 105 arranged parallel to the mounting hole 101; wherein the upper part of the sleeve 105 is connected to the mounting hole 101, so that after the product 300 is arranged in the mounting hole 101, its rod 301 is simultaneously inserted into the sleeve 105, and the rod 301 is a guide rod of the rocket product 300. In the prior art, when the rocket product 300 needs to be ignited, the guide rod needs to be inserted into the ground or other carriers and then ignited. However, for a harder ground, the guide rod cannot be inserted and cannot be ignited. For a place with many trees or houses, it is difficult to grasp the angle when the rocket is ignited, which is prone to safety accidents and cannot be ignited. Therefore, in this embodiment, the structure of the guide tube (i.e., the rod 301 of the product 300) is designed to be vertically inserted in the connecting device, which effectively solves the defects of being unable to insert the guide tube for ignition due to the hard ground and being unable to grasp the ignition angle due to the large number of trees or houses. In order to increase the stability of the connecting device, the sleeve 105 is provided with a reinforcing rib 105a.

[0045] In the specific implementation process, Figure 1 , Figure 3-Figure 7In order to facilitate the ignition of the rocket product 300 and to ignite the adjacent rocket products 300 in order at the same time, an ignition port 106 is provided on one side wall of the loading part 100 and is connected to the adjacent mounting hole 101, so that the fire source ignites the fuse of the first rocket product 300 on this side through the ignition port 106, and a groove 107 is provided on the other side wall, and an outlet 108 connected to the fuse area 102 is opened at the lower part of the groove 107. After the first rocket product 300 burns, the flame generated by it moves toward the outlet 108 to ignite the fuse of the adjacent rocket product 300 and then launch it into the air; Among them, the groove 107 and the ignition port 106 are symmetrically arranged on the left and right sides of the loading part 100, respectively, and the groove 107 and the ignition port 106 are opened along the height direction of the loading part 100. When the first rocket product 300 on one side of the connecting device is ignited, hot pressure and heat flow are generated in the connecting area 201 where the rocket product 300 is located. Since the upper part of the connecting area 201 is connected, the generated hot pressure and heat flow are introduced into the adjacent connecting area 201 to ignite the rocket product 300 therein, and finally multiple rocket products 300 in the connecting device are ignited and launched one by one.

[0046] Preferably, see Figure 1 , Figure 5 , Figure 6 , so that the first rocket product 300 on the upper side of the continuous lead device can be ignited, a horizontal plate 109 is provided on the ignition port 106 to divide the ignition port 106 into an upper and a lower part, and the lower part is symmetrical with the outlet 108, and the fuse on the first rocket product 300 can be laid on the horizontal plate 109, so as to facilitate rapid and accurate ignition. Furthermore, the ignition port 106 and the groove 107 are respectively provided on the vertical plate 104 on the corresponding side.

[0047] In a specific embodiment, see Figure 2 , Figure 3 , Figure 8 , Fig. 9, a raised portion 203 having a triangular longitudinal cross-section is provided in the connecting area 201, and the apex of the raised portion 203 faces the direction of the adjacent mounting hole 101, the inclined surface a where the apex is located extends into the adjacent mounting hole 101, and the inclined surface b where the apex is located is inclined downward into the connecting area 201, so that the raised portion 203 and the space corresponding to the lead area 102 above it together constitute the connecting area 201; wherein, there is a gap between the apex of the raised portion 203 and the lead area 102 in the vertical direction, so that the flame generated after the first product 300 to be ignited is ignited moves upward in the direction of the inclined surface b in the lead area 102, and moves along the direction of the inclined surface a after passing the upper part of the apex to ignite the adjacent product 300. Furthermore, the bottom end surface of the protrusion 203 is located in the connecting piece 200, that is, the connecting piece 200 is provided with a plurality of protrusions 203 connected in the first position, and the top surface of each protrusion 203 is the boundary surface of the adjacent connecting area 201. The protrusion 203 and the outer wall of the connecting piece 200 form a plurality of independent spaces, and each independent space is provided with a protrusion 203, and each rocket product corresponds to one protrusion 203 (that is, corresponds to one independent space, and is enclosed with the lead area 102 as a structure connected to the upper space).

[0048] In the specific implementation process, see Figure 8 , Fig. 9 After the first rocket product 300 in the connecting device is ignited, in order to prevent the generated flame from moving outward and make it move toward the adjacent rocket product 300, a block 204 is provided on the connecting piece 200 along its length direction, and the block 204 is located on the side where the ignition port 106 is provided, and the side of the block 204 facing the adjacent connecting area 201 is an inclined surface, and the inclination angle and size of the inclined surface are the same as those of the inclined surface a; wherein, the height of the block 204 is flush with the height of the protruding portion 203, and the generated flame moves downward under the action of gravity, and due to the action of the block 204, most of the flame moves toward the adjacent connecting area 201 to ignite the adjacent rocket product 300.

[0049] In order to allow the flame generated by the rocket product 300 to move in the connecting area 201 toward the adjacent rocket product 300 and facilitate the ignition efficiency of the first rocket product 300, the block 204 is flush with the bottom end surface of the ignition port 106.

[0050] Preferably, a baffle 205 is provided on the side of the connecting member 200 facing away from the stop block 204, and the baffle 205 is vertically arranged on the top surface of the connecting area 201 and abuts against the side wall of the loading member 100 to fix the connecting member 200; further, the top surface of the baffle 205 is flush with the bottom surface of the outlet 108, so that the heat flow in the connecting area 201 can be released from the outlet 108.

[0051] In a specific embodiment, the loading part 100 is symmetrically provided with a plug-in part 110 along its length direction, so as to fix the loading part 100 to the carrier and then ignite it. The carrier here is an object that can fix the connecting device, for example, an iron aluminum box, etc. It is only necessary to fix the connecting device so that the rocket product 300 can be placed vertically on the connecting device without being ignited. More specifically, see Figure 1 , Figure 2 , Figure 4-Figure 7 The plug plate 110 includes a first plug plate 110a and a second plug plate 110b, both of which have a ∪-shaped cross-section structure. The first plug plate 110a and the second plug plate 110b are arranged on the outer wall of the loading part 100; the tops of the first plug plate 110a and the second plug plate 110b are flush, and there is a gap in the width direction, so that the carrier is accommodated in the gap to fix the loading part 100 on the carrier, and the carrier at this place can be an aluminum box or an aluminum box, etc. More specifically, the bottom of the second plug plate 110b extends out of the bottom of the first plug plate 110a, that is, the height of the second plug plate 110b is greater than the height of the first plug plate 110a. Similarly, there is a gap between the second plug plate 110b and the outer wall of the loading part 100, and the carrier can be inserted into the gap between the second plug plate 110b and the loading part 100 and the gap between the first plug plate 110a and the second plug plate 110b at the same time, so as to further enhance the stability of the connecting device.

[0052] The connecting device designed in the utility model has a simple structure and is easy to operate, which improves the fun of the rocket product 300 and the user's experience, reduces the risk of launching, and reduces after-sales problems; at the same time, it solves the problem of limiting factors such as the environment and the site, making the launch angle and trajectory of the rocket product 300 more stable.

[0053] It should be noted that in the above embodiments, the description of each embodiment has its own emphasis, and for parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
