Description

Technical Field

[0001] The invention relates to the technical field of material conveying, and in particular to a clamping pipe fitting. Background Art

[0002] In the existing fireworks production process, fireworks need to be filled into the interior of the fireworks mold. With the development of the times, the cost of manually filling fireworks has gradually increased. In order to reduce the cost of filling fireworks molds with fireworks, our company's prior art "Patent No.: 202320170702.9, entitled: A Fireworks and Firecrackers Filling Production Line" can automatically fill fireworks molds with fireworks. However, because its loading method is that the loading assembly loads fireworks onto the loading plate of the loading assembly row by row, and then drives the loading plate carrying the fireworks to the top of the fireworks mold, and then pushes the fireworks into the fireworks mold through fixed loading; but because its loading method is that the loading assembly feeds materials row by row, and in the same section of the production line, only one loading assembly can be used to load materials, resulting in a slow production rhythm.

[0003] Based on the above problems, our company has conceived a structure that can rotate horizontally continuous fireworks to a vertical state, thereby speeding up production. However, how to ensure the stability of the fireworks when rotating, and how to facilitate the fireworks to enter the structure horizontally for temporary storage and then stably detach under the push of the ejector has become a difficult problem. Based on this technical problem, we provide a clamping tube. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides a clamping pipe fitting, which has the advantages of facilitating the horizontal transportation of cylindrical materials and automatically getting stuck inside the pipe fitting when the thrust is lost. This solves the problem that existing pipe fittings, pipelines and other structures used for horizontal cylindrical materials cannot automatically get stuck after the material loses thrust.

[0005] The clamping tube of the present invention can be applied to a fireworks and firecracker loading device or other equipment, including:

[0006] Pipe fitting body;

[0007] The pipe body is provided with a docking hole for the columnar material to pass through. The diameter of the docking hole is larger than the columnar material body, and a number of elastic limiters are provided inside the docking hole. In the initial state in the docking hole, the elastic limiters form a limit hole with a diameter smaller than that of the cylindrical material with the inner wall of the docking hole.

[0008] In some embodiments, the elastic limiting members are evenly distributed on the upper half of one side of the pipe body, and a bracket is formed on the lower half of the side of the pipe body where no elastic limiting member is provided.

[0009] In some embodiments, the end of the elastic limiting member and the end of the pipe body are in the same plane.

[0010] In some embodiments, the pipe body includes a fixing ring adapted to the docking hole, and the elastic limiting member is a plurality of arc-shaped pawls inclined toward the axis of the docking hole, and the plurality of arc-shaped pawls are fixedly connected to one side of the fixing ring in gaps, and the lower plate half on the same side of the fixing ring and the pawl extends horizontally outward to form an arc-shaped support plate, and a limiting hole is formed between the inner wall of the arc-shaped support plate and the end of the pawl; the bracket is the inner wall of the arc-shaped support plate.

[0011] In some embodiments, the other end of the fixing ring away from the pawl is further fixedly connected to a conical guide ring, and the conical guide ring expands toward the side away from the pawl.

[0012] In some embodiments, a bending groove is provided at the connection between the pawl and the fixing ring.

[0013] In some embodiments, the elastic limiting member is a spring fixedly installed inside the pipe body.

[0014] In some embodiments, the elastic limiting member may be a torsion spring, a spring cooperating with a limiting plate or a limiting block to change the docking hole into a limiting hole.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention provides a docking hole. After several devices are installed and docked on the same axis, several cylindrical materials that match the length of the device can be pushed in along the axis. When the material loses the thrust, it can automatically get stuck inside the pipe body. This makes it easy to adjust the material on the same axis and ensures the stability of the material during the adjustment process.

[0017] 2. The present invention facilitates the sliding of materials along the brackets through the provision of brackets. Since the materials are subjected to pressure on only one side in the pipe body, that is, the axis of the materials in the pipe body is close to the inner wall of the brackets, the sliding trajectory of the materials inside the pipe body is ensured to be constant. As long as the elastic limiter has elastic force to clamp the materials, the moving trajectory of the materials will not change, thereby ensuring a constant trajectory of the materials when they are subsequently pushed out of the pipe body, which is convenient for the accuracy of subsequent material docking.

[0018] 3. When the clamping tube of the present invention is used in fireworks and firecrackers loading equipment, it can solve the problem in the prior art that fireworks and firecrackers cannot be adjusted individually, especially solving the problem that fireworks and firecrackers have great safety hazards due to direct clamping alone, resulting in the existing equipment not having a mechanism for individually rotating and adjusting fireworks and firecrackers.

[0029] Example 1:

[0030] See also Figures 1-4 The clamping pipe fitting of the present invention comprises:

[0031] Pipe fitting body 1;

[0032] The pipe body 1 is provided with a docking hole 2 for the columnar material 7 to pass through. The diameter of the docking hole 2 is larger than the body of the columnar material 7, and a number of elastic limit members 6 are provided inside the docking hole 2. In the initial state of the elastic limit member 6 in the docking hole 2, a limit hole 3 with a diameter smaller than that of the cylindrical material 7 is formed on the inner wall of the docking hole 2.

[0033] The elastic limiting members 6 are evenly distributed on the upper half of one side of the pipe body 1 , and the brackets 4 are formed on the lower half of the side of the pipe body 1 where the elastic limiting members 6 are not provided.

[0034] Working principle:

[0035] By setting the docking hole 2, after several devices are installed and docked on the same axis, several cylindrical materials 7 with a length compatible with the device can be pushed in along the axis. The materials 7 will be located inside the pipe body 1 one by one. Because the pipe body 1 is provided with an elastic limiter 6, and a limit hole 3 with a diameter smaller than the material 7 is formed between the elastic limiter 6 and the inner wall of the docking hole 2, when the material 7 loses the thrust, it can automatically get stuck inside the pipe body 1; thereby facilitating the adjustment of the material 7 on the same axis and ensuring the stability of the material 7 during the adjustment process;

[0036] And the arrangement of the bracket 4 can facilitate the sliding of the material 7 along the bracket 4, especially during horizontal transportation, because only the elastic limit member 6 located above exerts pressure on the material 7, which can ensure the stability of horizontal sliding; and because the material 7 is only subjected to pressure from one side in the pipe body 1, that is, the axis of the material 7 in the pipe body 1 is close to the inner wall of the bracket 4, it ensures that the sliding trajectory of the material 7 inside the pipe body 1 is constant, and as long as the elastic limit member 6 has the elastic force to clamp the material 7, the moving trajectory of the material 7 will not change, thereby ensuring that the trajectory of the material 7 when it is subsequently pushed out of the pipe body 1 is constant, which is convenient for the subsequent accuracy of the material 7 when docking.

[0037] Specifically, the pipe body 1 includes a fixing ring 101 that is adapted to the docking hole 2, and the elastic limiter 6 is a plurality of arc-shaped pawls 102 inclined toward the axis of the docking hole 2, and the plurality of arc-shaped pawls 102 are fixedly connected to one side of the fixing ring 101 with gaps, and the lower plate half on the same side of the fixing ring 101 and the pawl 102 extends horizontally outward to form an arc-shaped support plate 103, and a limiting hole 3 is formed between the inner wall of the arc-shaped support plate 103 and the end of the pawl 102; the bracket 4 is the inner wall of the arc-shaped support plate 103.

[0038] The other end of the fixing ring 101 away from the pawl 102 is also fixedly connected to a conical guide ring 5 , which expands toward the side away from the pawl 102 , thereby facilitating the guidance of the cylindrical material 7 into the interior of the fixing ring 101 .

[0039] The end of the elastic limiter 6 is in the same plane as the end of the pipe body 1 , so that the material 7 can be limited by the elastic limiter 6 before it leaves the pipe body 1 , further ensuring the stability of the material 7 when it leaves the pipe body 1 .

[0040] A bending groove 8 is provided at the connection between the pawl 102 and the fixing ring 101 to facilitate bending of the pawl 102 .

[0041] Example 2:

[0042] See also Figure 5 As a variation of the second embodiment, the elastic limiting member 6 is a spring piece fixedly installed inside the pipe body 1.

[0043] See also Figure 6 The elastic limiting member 6 can be a torsion spring, a spring, a limiting plate or a limiting block to change the docking hole 2 into a limiting hole 3.

[0044] Working principle:

[0045] This embodiment provides several different elastic limiting members 6 , which can all play the role of the first embodiment to a certain extent in actual use.

[0046] Example 3:

[0047] A fireworks and firecrackers filling device includes a clamping tube according to the first or second embodiment. When the mechanism is applied to the fireworks and firecrackers filling device.

[0048] Working principle:

[0049] Push the fireworks into the docked clamping tube. When the fireworks lose their thrust, they will automatically get stuck inside the tube body 1. Then, by adjusting the position of the clamping tube, the state of the fireworks can be changed, such as rotating it from a horizontal state to a vertical state. When the fireworks are adjusted to face the fireworks mold, the conventional loading mechanism on the existing fireworks loading equipment is used, that is, the ejector pin is pushed by the gas rod to push the fireworks into the fireworks mold.

[0050] That is, when the clamping tube is used in the fireworks and firecrackers loading equipment, it not only has the advantages of embodiment 1, but also can solve the problem in the prior art that the fireworks and firecrackers cannot be adjusted individually, especially solving the problem that the fireworks and firecrackers have a greater safety hazard due to being directly clamped individually, resulting in the existing equipment not having a mechanism for individually rotating and adjusting the fireworks and firecrackers.

[0051] Among them, fireworks and firecrackers and fireworks molds can be called fireworks inner tubes and fireworks balls in the fireworks field.

[0052] The above is merely an embodiment of the present invention and is not intended to limit the present invention. It will be apparent to those skilled in the art that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are intended to be included within the scope of the claims of the present invention.
