Description

Technical Field

[0001] The invention relates to the technical field of explosive charges, in particular to a safe fireworks ignition base. Background Art

[0002] When fireworks are set off, they need to be assisted by the base to ensure that the fireworks remain upright during the setting off process and prevent them from falling over, so that the fireworks can be launched at the designed angle and direction to ensure the setting off effect and safety. At the same time, the tube or body of the fireworks is firmly fixed on the base to avoid shaking, displacement or falling off during transportation, handling or setting off preparation, and to ensure that the relative positions of the various parts of the fireworks are accurate. Technical inspiration for the setting off base;

[0003] Research on the firing base revealed the following issues:

[0004] The firing base is usually embedded in the ground, and the firework tube is fixed by penetrating the soil. When the firework tube is fired, the firework tube generates impact, so the firework tube generates a certain impact on the firing base. Since the soil is usually soft, the firing base is easy to tilt during the firing of the firework, which increases the safety hazard during the firing of the firework, and causes the firing base to be unable to avoid the firework tube from continuously tipping over after tilting;

[0005] At the same time, the firing base is usually simply nested and docked with the firework tube. During transportation, the firing base and the firework tube are easy to fall off, which can cause the firework materials inside the firework tube to leak, increasing the safety risks during the overall transportation of fireworks.

[0006] At present, CN201310694305.2 in the prior art discloses a base for a combination of fireworks. The base of the invention has a bottom plate with a bottom edge and a bottom foot, and a plurality of cylindrical joints are provided on the bottom plate. A fuse groove is provided on the bottom surface of the bottom plate, and a fuse hole is provided between the cylindrical joint and the fuse groove. When the present invention is used, a long paper roll is inserted and fixed outside each cylindrical joint of the base to form a fireworks launch tube, and the fireworks propellant is loaded in the inner cavity of the cylindrical joint. The base is flat in shape, and the product is pressed as a whole using a relatively low material density. The process is simple and easy to recycle. The cost is low, the quality is good, and there are no pores or shrinkage. Since the fireworks propellant is loaded in the inner cavity of the cylindrical joint, the tube will not explode when the propellant is burned. Therefore, the combination fireworks produced by the invention can ensure the quality of the fireworks and the firing effect without any safety hazards. It is light in weight and can be recycled and is environmentally friendly.

[0007] The present invention can mainly solve the problem that a firing base cannot prevent a firework tube from continuously tipping over after being tilted. Summary of the invention

[0008] In order to solve the above technical problems, the present invention provides a fireworks safe firing base to solve the problems described in the above background technology.

[0009] The purpose and effect of a fireworks safe firing base of the present invention are achieved by the following specific technical means: a fireworks safe firing base, including a support leg, the upper end of the support leg is sequentially arranged with a support and a bottom plate, and the upper end of the bottom plate is provided with an insert block.

[0010] Furthermore, the support leg is in a cone shape, and holes are passed through the interior of the support pillar. The holes are arranged in a vertical direction, and the support leg and the support pillar are integrally penetrated underground.

[0011] Furthermore, the bottom plate is a wavy disc, a groove is provided at the upper end of the bottom plate, and holes are provided on the inner wall of the groove of the bottom plate, with 6 to 8 holes.

[0012] Furthermore, the holes of the base plate are respectively inlaid with snap rings, the side of the snap ring away from the base plate is arranged in an arc shape, and the inner wall of the other side of the snap ring is provided with a sliding groove, and the sliding groove is arranged vertically.

[0013] Furthermore, the insert block is docked with the inside of the firework tube, and one end of the firework tube is nested and docked with the groove of the bottom plate.

[0014] Furthermore, a slider is slidably connected inside the slide groove of the clamping ring, a ball is hinged on one side of the slider, and a push rod is swingably connected to one arc-shaped end of the ball close to the clamping ring.

[0015] Furthermore, the slider slides in a vertical direction, and when the push rod is not pressed to one end of the slider, the slider is located at the lower end of the retaining ring slot.

[0016] Furthermore, the weight of the slider is 200-400g.

[0017] Furthermore, the push rod takes the sphere as a starting point, is tilted downward by 25-60 degrees, and one end of the push rod away from the sphere is connected to the inner wall of the arc-shaped end of the clamping ring.

[0018] Furthermore, an outer box is penetrated inside the hole of the pillar, a track is penetrated at the upper end of the inner wall of the outer box, a sliding ball is slidably connected inside the track, an inclined block is provided at the lower end of the sliding ball, and bottom rods are slidably penetrated on both sides of the inner part of the outer box.

[0019] Furthermore, the interior of the outer box is hollow, the outer box as a whole is cross-arranged, and the length of the outer box is 1-2 cm greater than the diameter of the top of the pillar.

[0020] Furthermore, the outer boxes are arranged crosswise as a whole, so when the bottom plate tilts to one side, one of the outer boxes on the outside of the support can tilt synchronously.

[0021] Furthermore, the track is arranged in an arc shape as a whole, and the arc angle is 180 degrees. A groove is penetrated through the lower end of the track, and the inclined block penetrates the inside of the groove and extends to the bottom of the track, and the sliding ball slides downward inside the track.

[0022] Furthermore, the sliding ball is elliptical in shape, and is matched with the inclined block. Both sides of the lower end of the inclined block are inclined at an angle of 45-90°, and the lower end of the inclined block is respectively slidably extruded with the bottom rod.

[0023] Furthermore, the lower end of the bottom rod is conical, and the side surface of the bottom rod is "T"-shaped. When the inclined block is not pressed to the upper end of the bottom rod, the upper end of the bottom rod is in contact with the upper end of the inner wall of the outer box.

[0024] Beneficial effects:

[0025] 1. One end of the firework tube is clamped to the inner side of the bottom plate, and the outer wall of the firework tube is squeezed to the arc-shaped end of the clamp ring. The clamp ring is deformed toward one side of the push rod due to the squeezing, and the push rod is driven by the ball to slide upward, and the push rod slides upward inside the slide groove of the clamp ring. Since the weight of the slider is 200-400g, as the slider gradually slides inside the slide groove of the clamp ring, the slider forms a reverse squeeze on one side of the push rod by using the downward gravity of the slider, and the push rod can form a reverse squeeze on the arc-shaped end of the clamp ring, and then the push rod can assist the clamp ring to form a reverse limit squeeze on the outer wall of the firework tube, which can prevent the firework tube from falling off from the bottom plate during transportation, and thus prevent the internal firework material from leaking after the firework tube falls off from the bottom plate;

[0026] 2. When the pillar is embedded in the ground, the bottom rod is embedded in the ground synchronously. When the firework tube tilts to one side, one of the outer boxes outside the pillar tilts synchronously. Through the overall tilt of the outer box, the sliding ball inside the outer box can slide inside the track. The bottom rod is located on both sides of the outer box. The sliding ball slides toward one side of the track, and the sliding ball can drive the inclined block to slide toward one side of the bottom rod;

[0027] 3. Since both sides of the lower end of the inclined block are inclined at an angle of 45-90°, when the inclined block slides toward one side of the inner part of the outer box, the inclined block is squeezed to the upper end of the bottom rod, and the inclined block can assist the bottom rod to slide downward inside the outer box, and the bottom rod can be further embedded in the ground. Therefore, when the firework tube is tilted, the bottom rod can be further embedded in the ground without affecting the previous embedding in the ground, so that when the firework tube is tilted, the firing base can further fix the firework tube through the bottom rod, thereby avoiding the situation where fireworks are splashed due to the tilt of the firework tube during the firing process, thereby improving the safety during the firing process.

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] Example:

[0041] As attached Figure 1 To Attachment Fig. 9 As shown:

[0042] Embodiment 1: A fireworks safe setting off base, comprising a support leg 1, the upper end of which is sequentially provided with a support 101 and a bottom plate 102, and an insert block 103 is provided at the upper end of the bottom plate 102;

[0043] Among them: the support leg 1 is conical, the support leg 101 has holes running through it, the holes are arranged in a vertical direction, and the support leg 1 and the support leg 101 are integrally penetrated underground;

[0044] The bottom plate 102 is a wavy disk. A groove is formed at the top of the bottom plate 102. The inner wall of the groove of the bottom plate 102 is provided with holes. There are 6 to 8 holes. Figure 3 As shown;

[0045] The holes of the bottom plate 102 are inlaid with snap rings 2, the side of the snap ring 2 away from the bottom plate 102 is arranged in an arc shape, and the inner wall of the other side of the snap ring 2 is provided with a slide groove, which is arranged vertically. The snap ring 2 is made of a deformable material, such as rubber;

[0046] The insert block 103 is connected to the inside of the firework tube, and one end of the firework tube is nested and connected to the groove of the bottom plate 102;

[0047] Among them: one end of the firework tube is nested and docked with the groove of the bottom plate 102. Since the bottom plate 102 is a wavy disc, the arched end inside the bottom plate 102 fits tightly with one end of the firework tube. Then the support leg 1 and the support 101 are integrally penetrated into the ground, so that the firework tube can be fixed, and then the firework tube is ignited;

[0048] Example 2: Refer to the attached manual Figure 1-5 It can be seen that the difference between Example 2 and Example 1 is that a slider 201 is slidably connected inside the slide groove of the clamping ring 2, a ball 202 is hinged on one side of the slider 201, and a push rod 203 is swingably connected to the arc end of the ball 202 close to the clamping ring 2;

[0049] Wherein: the slider 201 slides in a vertical direction, and when the push rod 203 is not pressed to one end of the slider 201, the slider 201 is at the lower end of the slide groove of the clamping ring 2;

[0050] The weight of the slider 201 is 200-400g;

[0051] The push rod 203 takes the ball 202 as a starting point, and the push rod 203 is inclined downward by 25-60 degrees, and one end of the push rod 203 away from the ball 202 is connected to the inner wall of the arc end of the clamping ring 2;

[0052] Wherein: one end of the firework tube is clamped to the inner side of the bottom plate 102, and the outer wall of the firework tube is squeezed to the arc-shaped end of the clamp ring 2. The clamp ring 2 is deformed toward one side of the push rod 203 due to the squeezing, and the push rod 203 is driven by the ball 202 to slide upward, and the push rod 203 slides upward inside the slide groove of the clamp ring 2. Since the weight of the slider 201 is 200-400g, as the slider 201 gradually slides inside the slide groove of the clamp ring 2, the slider 201 forms a reverse squeeze on one side of the push rod 203 by utilizing the downward gravity of the slider 201, and the push rod 203 can form a reverse squeeze on the arc-shaped end of the clamp ring 2, and then the push rod 203 can assist the clamp ring 2 to form a reverse limiting squeeze on the outer wall of the firework tube, which can prevent the firework tube from easily falling off from the bottom plate 102 during transportation, and then prevent the internal firework material from leaking after the firework tube and the bottom plate 102 fall off;

[0053] Example 3: Refer to the attached manual Figure 6-9 It can be seen that the difference between Example 3 and Examples 1 and 2 is that the outer box 3 is penetrated inside the hole of the pillar 101, the upper end of the inner wall of the outer box 3 is penetrated by a track 302, the inside of the track 302 is slidably connected with a sliding ball 4, the lower end of the sliding ball 4 is provided with an inclined block 401, and the bottom rods 301 are slidably penetrated on both sides of the inner part of the outer box 3;

[0054] Wherein: the interior of the outer box 3 is hollow, the outer box 3 is arranged crosswise as a whole, and the length of the outer box 3 is 1-2 cm greater than the top diameter of the support 101;

[0055] The outer boxes 3 are arranged crosswise as a whole, so when the bottom plate 102 tilts to one side, one of the outer boxes 3 outside the support 101 can tilt synchronously;

[0056] The length of the outer box 3 is 1-2 cm greater than the top diameter of the support 101, so that the bottom rods 301 on both sides of the outer box 3 can be easily embedded in the ground;

[0057] The track 302 is arranged in an arc shape as a whole, and the arc angle is 180°. A groove is penetrated at the lower end of the track 302, and the inclined block 401 penetrates the inside of the groove and extends to the bottom of the track 302, and the sliding ball 4 slides downward inside the track 302;

[0058] The sliding ball 4 is oval-shaped, and is matched with the inclined block 401. Both sides of the lower end of the inclined block 401 are inclined, and the inclination angle is 45-90 degrees. The lower end of the inclined block 401 is respectively slidably extruded with the bottom rod 301;

[0059] Both sides of the lower end of the inclined block 401 are inclined at an angle of 45-90 degrees, so when the inclined block 401 slides toward one side of the inner part of the outer box 3, the inclined block 401 can be pressed to the upper end of the bottom rod 301, and the inclined block 401 can assist the bottom rod 301 to slide downward inside the outer box 3;

[0060] The lower end of the bottom rod 301 is conical, and the side of the bottom rod 301 is "T" shaped. When the inclined block 401 is not pressed to the upper end of the bottom rod 301, the upper end of the bottom rod 301 is in contact with the upper end of the inner wall of the outer box 3;

[0061] When the inclined block 401 is not pressed to the upper end of the bottom rod 301, the upper end of the bottom rod 301 is in contact with the upper end of the inner wall of the outer box 3, so that the bottom rod 301 can be quickly penetrated into the ground.

[0062] When the pillar 101 is embedded in the ground, the bottom rod 301 is embedded in the ground synchronously. When the firework tube tilts to one side, one of the outer boxes 3 outside the pillar 101 tilts synchronously. When the outer box 3 tilts as a whole, the sliding ball 4 inside the outer box 3 can slide inside the track 302. The bottom rod 301 is located on both sides of the outer box 3. The sliding ball 4 slides toward one side of the track 302, and the sliding ball 4 can drive the inclined block 401 to slide toward one side of the bottom rod 301.

[0063] Since both sides of the lower end of the inclined block 401 are inclined with an angle of 45-90°, when the inclined block 401 slides toward one side of the inner part of the outer box 3, the inclined block 401 can be squeezed to the upper end of the bottom rod 301, and the inclined block 401 can assist the bottom rod 301 to slide downward inside the outer box 3, and the bottom rod 301 can be further embedded in the ground. Therefore, when the firework tube is tilted, the bottom rod 301 can be further embedded in the ground without affecting the previous embedding in the ground, so that when the firework tube is tilted, the firing base can further fix the firework tube through the bottom rod 301, thereby avoiding the situation where fireworks are splashed due to the tilt of the firework tube during the firing process, thereby improving the safety during the firing process.
