DETAILED DESCRIPTION

[0032] 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.

[0033] Depend on Figure 1-9 The present invention relates to a flame marquee, comprising an upper shell 1, a lower shell 2, a flame lamp board 3 and a sealing cover 4, wherein the upper shell 1 and the lower shell 2 are detachably matched, the flame lamp board 3 is fixedly arranged on the upper shell 1, and the sealing cover 4 is detachably arranged on the lower shell 2; two upper conductive pillars 5 are symmetrically fixedly arranged on the flame lamp board 3, and the two upper conductive pillars 5 pass through two circular holes on the upper shell 1 and are placed inside the upper shell 1; an upper cavity 6 and a lower cavity 7 are formed inside the lower shell 2, the upper cavity 6 is connected with the lower cavity 7, a circuit board 8 is fixedly arranged in the lower cavity 7, two lower conductive pillars 9 are fixedly arranged on the circuit board 8, and the two upper conductive pillars 5 are respectively docked with the two lower conductive pillars 9;

[0034] With such a design, when in use, the upper conductive column 5 on the upper shell 1 is connected with the downward conductive column 9 on the lower shell 2, and then the upper shell 1 and the lower shell 2 can be installed together, such as directly snapping the two together by interference fit, or installing the two together by threading, and the sealing cover 4 can also be installed in the same way; it should be noted that a transparent protective cover can be provided on the outside of the flame lamp panel 3, and a control switch, a charging interface, a battery and other structures are provided on the lower shell 2 to ensure the normal use of the flame marquee; since the above contents are all prior art, they will not be described in detail.

[0035] In order to solve the problem that during the installation of the existing flame marquee, some of the conductive columns are installed manually, and the installation is not precise enough, which will cause some parts of the upper and lower conductive columns to be in contact and some not to be in contact, resulting in poor contact and virtual connection, which poses a safety hazard, the following technical solutions are now provided to solve the above technical problems:

[0036] The upper conductive column 5 includes an upper cylinder 10, which is fixedly arranged on the flame lamp board 3. The upper cylinder 10 is symmetrically formed with arc-shaped portions 11, which are recessed from the outer side of the upper cylinder 10 to the inner side of the upper cylinder 10, and the two arc-shaped portions 11 are both provided with a clamping groove 12;

[0037] The lower conductive column 9 includes an outer cylinder 13 and an inner cylinder 14 connected as one body. The outer cylinder 13 and the inner cylinder 14 are fixedly arranged on the circuit board 8. An annular clamping ring 15 is formed on the inner cylinder 14. The upper surface and the lower surface of the clamping ring 15 are formed with inclined portions 16. The outer wall of the clamping ring 15 forms a side wall portion 17. The side wall portion 17 is located between the two inclined portions 16.

[0038] The design is such that, when in use, when the upper cylinder 10 is placed inside the outer cylinder 13 and the inner cylinder 14, as the upper cylinder 10 moves, under the action of the inclined portion 16, the side wall portion 17 of the clamping ring 15 squeezes the arc portion 11 on the upper cylinder 10, and then the side wall portion 17 enters the inside of the clamping groove 12 on the arc portion 11. After installation is completed, under the squeezing action of the side wall portion 17 on the clamping groove 12, the arc portion 11 on the upper cylinder 10 is compressed and transmits the force to the position between the two arc portions 11 on the upper cylinder 10, so that the upper cylinder 10 and the outer cylinder 13 fit more closely, thereby improving the conductivity after installation by increasing the conductive area. In addition, since the side wall portion 17 is also limited by the clamping groove 12 after installation, the separation of the two requires a greater force to separate, thereby improving the stability of the connection between the upper conductive column 5 and the lower conductive column 9.

[0039] Specifically, the upper conductive column 5 is provided with a plurality of slots 18 along its circumference, and the plurality of slots 18 are all located above the snap-in slot 12. With such a design, when the upper shell 1 is separated from the lower shell 2, since the lower conductive column 9 is located inside the upper cavity 6, it is not easily damaged by external forces. Since the upper conductive column 5 is partially exposed to the outside, the arrangement of the slots 18 can enable the upper cylinder 10, that is, the upper conductive column 5, to have a certain deformation ability, that is, the external force applied is not too large and damage will not occur. Moreover, the contact point between the upper conductive column 5 and the lower conductive column 9 may cause the surrounding temperature to rise due to the power supply. In this way, the arrangement of the slots 18 can ensure fluidity and avoid heat accumulation between the upper cylinder 10 and the inner cylinder 14.

[0040] It should be noted that the material of the upper conductive pillar 5 and the lower conductive pillar 9 can be selected according to actual needs, such as being made of stainless steel, copper sheet and other materials.

[0041] Specifically, an integral guide ring 19 is formed at the mouth of the outer cylinder 13, and the guide ring 19 expands from the inner side of the outer cylinder 13 to the outer side of the outer cylinder 13. An integral conical cylinder 20 is formed on the inner cylinder 14, and the radius of the end of the conical cylinder 20 away from the inner cylinder 14 is smaller than the radius of the end of the conical cylinder 20 close to the inner cylinder 14. Such a design makes it easy for users to insert the upper cylinder 10 between the outer cylinder 13 and the inner cylinder 14 through the cooperation of the guide ring 19 and the conical cylinder 20, and the operation is convenient.

[0042] Specifically, a center hole 21 is opened at the top of the conical cylinder 20, and a plurality of strip holes 22 are opened on the side wall of the conical cylinder 20; such a design can prevent heat from accumulating inside the inner cylinder body 14, and the heat can be discharged through the center hole 21, the strip holes 22, and the notch 18.

[0043] In order to improve the sealing performance between the upper shell 1 and the lower shell 2 , an integral pressure ring 23 is connected to the upper shell 1 , and a sealing groove 24 is formed on the lower shell 2 , in which a sealing ring 25 is arranged.

[0044] In order to quickly realize the installation of the circuit board 8, a plurality of mounting posts 26 are fixedly arranged on the inner top wall of the lower cavity 7, and a plurality of mounting holes 27 are opened on the circuit board 8. The mounting posts 26 are arranged one by one corresponding to the mounting holes 27. The top shape of the mounting posts 26 is cylindrical, the bottom shape of the mounting posts 26 is elliptical, and a central groove 28 is opened inside the mounting posts 26.

[0045] With this design, when in use, the mounting hole 27 on the circuit board 8 is directly aligned with the mounting post 26, and then pressed hard to complete the installation process. The specific process is: the elliptical part of the mounting post 26 is first squeezed by the mounting hole 27 and then tilted toward the center groove 28. When the mounting hole 27 enters the columnar part of the mounting post 26, under its own force, the elliptical part on the mounting post 26 blocks the mounting hole 27, completing the installation process.

[0046] Furthermore, an inner cavity 29 is formed inside the sealing ring 25, a plurality of connecting grooves 30 are formed inside the lower shell 2, a docking groove 31 and a spherical groove 32 are provided inside the mounting column 26, wherein the docking groove 31 is located at the cylindrical part of the mounting column 26, the spherical groove 32 is located at the elliptical part of the mounting column 26, an elastic airbag 33 is provided inside the spherical groove 32, the elastic airbag 33 is fixedly connected with a connecting pipe 34, and the connecting pipe 34 passes through the docking groove 31 and the connecting groove 30 in sequence and then is fixedly connected with the inner cavity 29;

[0047] With such a design, after the upper shell 1 and the lower shell 2 are installed together, the pressure ring 23 on the upper shell 1 squeezes the sealing ring 25 in the lower shell 2, so that the pressure in the inner cavity 29 in the sealing ring 25 increases, and the pressure is transmitted to the inside of the elastic airbag 33 through the connecting tube 34, so that the elastic airbag 33 expands. The expanded elastic airbag 33 squeezes the spherical groove 32 on the mounting column 26, so that the two sides of the mounting column 26 are pressed and fit more closely with the mounting hole 27 on the circuit board 8, thereby further improving the stability of the circuit board 8 after installation and avoiding loosening.

[0048] Specifically, the elliptical portion of the mounting column 26 protrudes from the inner side of the mounting column 26 to the outer side of the mounting column 26, and the radius size of the end of the mounting column 26 away from the connecting tube 34, the radius size of the cylindrical portion of the mounting column 26, and the radius size of the outer diameter of the elliptical portion of the mounting column 26 increase successively; such a design makes it easy for users to dock the mounting hole 27 on the circuit board 8 with the mounting column 26, thereby increasing the possibility of successful docking.

[0049] Specifically, a sealing gasket 35 is provided at the connection between the lower shell 2 and the sealing cover 4, and an outer groove body 36 is opened on the sealing cover 4, and an integrated knob 37 is connected to the interior of the outer groove body 36; with this design, when maintenance is required, the sealing cover 4 can be disassembled by turning the knob 37.

[0050] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
