Description

Technical Field

[0001] This utility model relates to the field of warning device technology, and in particular to a portable warning flag. Background Technology

[0002] In situations involving large gatherings, warnings are often issued via loudspeakers or other means, including using flags with text, known as informational flags, to display information to relevant personnel. These flags typically consist of two flagpoles that unfurl the flag. Multiple flags are usually provided, each with a different background color and text. To use one, the flag with the desired text is picked up, unfolded, and held by both flagpoles. While some flags are connected to the flagpoles via interlocking mechanisms, others are fixed. Regardless of the connection method, the unfolding and / or rolling process is relatively cumbersome, which can delay the notification process in chaotic situations. Furthermore, rolled-up flags can only be stored in containers such as storage boxes, and currently, there are no easily portable storage containers available, making them difficult to carry and significantly inconvenient for storage and retrieval. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a portable information flag that improves portability, makes it easy to store and retrieve, and is easy to unfold and fold.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a portable notification flag, comprising a main flagpole and two auxiliary flagpoles. Two inner flagpoles are rotatably installed inside the main flagpole, and flags are fixed on the two inner flagpoles respectively. The outer ends of the two flags extending from the side wall of the main flagpole are connected to the two auxiliary flagpoles respectively. The side wall of the main flagpole is provided with retraction openings corresponding to the two flags respectively. A spring is installed inside the main flagpole to drive the inner flagpoles to retract the corresponding flags.

[0005] As a preferred technical solution, the main flagpole includes a hollow main body, with inner pole mounting seats interference-fitted into both ends of the main body. Each inner pole mounting seat has a rotating connection hole corresponding to the inner flagpole. The distal surfaces of the two inner pole mounting seats each have a spring mounting groove located at the rotating connection hole. The end of the inner flagpole extends out of the rotating connection hole and into the spring mounting groove. A spring is installed between the end of the inner flagpole and the spring mounting groove. Main pole end caps are fastened to both ends of the main body.

[0006] As a preferred technical solution, a main rod handle is installed at one end of the main rod body, and a main rod connecting hole is provided through the inner rod mounting seat near the main rod handle. A main rod connecting tube corresponding to the main rod connecting hole is integrally provided on the proximal end face of each of the two inner rod mounting seats. A main rod connecting rod is fixedly provided on the main rod handle, and the main rod connecting rod is inserted into the two main rod connecting tubes. A main rod clearance opening corresponding to the main rod connecting rod is provided on the main rod end cap near the main rod handle.

[0007] As a preferred technical solution, three circumferentially arranged end cap retaining protrusions are fixedly provided at both ends of the main rod body, and the inner wall of the main rod end cap is provided with end cap retaining grooves corresponding to the end cap retaining protrusions.

[0008] As a preferred technical solution, the inner flagpole includes two symmetrical half-poles, with the inner end of the flag sandwiched between the two half-poles, and a pole-forming screw connecting the two half-poles.

[0009] As a preferred technical solution, the outer end of the flag is provided with a secondary pole connecting sleeve for the secondary flagpole to be inserted, and the secondary pole connecting sleeve is provided with a pre-tightening operating lug.

[0010] As a preferred technical solution, the content on the two sides of the same flag is set differently.

[0011] As a preferred technical solution, the main flagpole is fitted with a buckle, and the buckle is provided with a belt connecting part.

[0012] By adopting the above technical solution, the portable information flag includes a main flagpole and two auxiliary flagpoles. Two inner flagpoles are rotatably installed inside the main flagpole, and flags are fixed to each of the two inner flagpoles. The outer ends of the two flags extending from the side wall of the main flagpole are connected to the two auxiliary flagpoles respectively. The side wall of the main flagpole is provided with openings corresponding to the two flags. A spring is installed inside the main flagpole to drive the inner flagpoles back to their corresponding flags. In use, the auxiliary flagpoles can be pulled directly by hand to overcome the spring force of the spring, thus pulling out the flags and displaying the desired content. After releasing the pulling force, the flags automatically retract under the spring force of the spring, making unfolding and folding quick and convenient. This utility model uses one main flagpole and two secondary flagpoles to install two flags. The flags can display four different contents by setting the contents on the two sides. Thus, this utility model is equivalent to integrating the existing four flags into a single component. Since the single component is in the state of three flagpoles together after the flags are folded up, it can be stored by fixing the main flagpole. Storage and retrieval are very quick and convenient, and the portability is also improved. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0026] like Figure 1 As shown, a portable notification flag includes a main flagpole 1 and two auxiliary flagpoles 7. Two inner flagpoles 3 are rotatably installed inside the main flagpole 1, and flags 4 are fixed on the two inner flagpoles 3 respectively. The outer ends of the two flags 4 extending out of the side wall of the main flagpole 1 are connected to the two auxiliary flagpoles 7 respectively. The side wall of the main flagpole 1 is provided with retraction openings 12 corresponding to the two flags 4 respectively. A spring 5 for driving the inner flagpoles 3 to retract the corresponding flags 4 is installed inside the main flagpole 1.

[0027] like Figure 9 As shown, in the absence of external force, the flag 4 is rolled up onto the corresponding inner flagpole 3, and the spring 5 provides a spring force in the direction of continued rolling, causing the two secondary flagpoles 7 to come together on the main flagpole 1. Figure 1 and Figure 2 As shown, in use, the flag 4 can be pulled out by manually overcoming the spring force of the spring 5 and displaying the desired content; after releasing the pulling force, the flag 4 automatically rolls back under the spring force of the spring 5, making it quick and convenient to unfold and retract.

[0028] Among them, such as Figures 3 to 7 As shown, the main flagpole 1 includes a hollow main pole body 11. Inner pole mounting seats 2 are respectively interference-fitted into both ends of the main pole body 11. The inner pole mounting seats 2 are provided with rotating connection holes 21 corresponding to the inner flagpole 3. The two ends of the inner flagpole 3 are respectively inserted into the rotating connection holes 21 on the two inner pole mounting seats 2 to form a rotating installation.

[0029] The distal surfaces of the two inner rod mounting seats 2 are respectively provided with spring mounting grooves 22 located at the rotating connection holes 21. The end of the inner flag rod 3 extends out of the rotating connection holes 21 and into the spring mounting grooves 22. The spring spring 5 is installed between the end of the inner flag rod 3 and the spring mounting grooves 22. More specifically, as shown... Figure 8As shown, the inner flagpole 3 has an inner spring retaining groove 51 at its end extending into the spring mounting groove 22. The groove wall of the spring mounting groove 22 has a spring retaining protrusion 53. The outer end of the spring spring 5 has an outer spring retaining groove that engages with the spring retaining protrusion 53. The inner end of the spring spring 5 has an integrally bent inner spring retaining part 52 that engages within the inner spring retaining groove 51. When the flag 4 is pulled outwards, the inner flagpole 3 rotates forward, driving the inner spring retaining part 52 through the inner spring retaining groove 51. The inner coil of the spring spring 5 gradually winds around the inner flagpole 3, maintaining its spring force. When the external pulling force on the flag 4 is released, the spring spring 5 recovers its deformation against the groove wall of the spring mounting groove 22, causing the inner flagpole 3 to rotate, and the flag 4 is wound up by the inner flagpole 3.

[0030] Preferably, the inner flagpole 3 includes two symmetrical half-poles 31, with the inner end of the flag 4 sandwiched between the two half-poles 31, and a pole-forming screw 32 connecting the two half-poles 31. The inner flagpole 3 is configured as a cylindrical pole structure with two half-poles 31 fixed by the pole-forming screw 32, which facilitates the fastening of the inner end of the flag 4 and is simple and easy to manufacture. To reduce the overall weight of this embodiment, the half-poles 31 are preferably made of plastic, but can also be made of lightweight metals such as aluminum. The inner pole mounting base 2 is preferably made of plastic.

[0031] Main shaft body 11 has end caps 13 fastened to both ends. The end caps 13 serve two purposes: first, to seal both ends of the main shaft body 11, reducing dust and water contamination; and second, to form a closed space with the spring mounting groove 22, ensuring stable and reliable operation of the spring spring 5 within the groove. Preferably, the end caps 13 and the main shaft body 11 are interference-fitted to ensure stability after installation. Preferably, three circumferentially arranged end cap retaining protrusions 14 are fixed at both ends of the main shaft body 11, and the inner wall of the end caps 13 has end cap retaining grooves 15 corresponding to the protrusions 14. The rigidity of the protrusions and grooves further enhances the stability of the end caps 13. The main rod end cap 13 is preferably made of plastic, and the main rod body 11 is preferably made of stainless steel thin-walled steel pipe. The end cap holding protrusion 14 is formed by applying pressure outward in a point-like manner to plastically deform the pipe wall. This is something that those skilled in the art can easily derive by combining conventional technical means, and will not be elaborated here.

[0032] Furthermore, a main rod handle 6 is installed at one end of the main rod body 11. A main handle connection hole 61 is provided through the inner rod mounting base 2 near the main rod handle 6. A main handle connection tube 62 corresponding to the main handle connection hole 61 is integrally provided on the near end face of each of the two inner rod mounting bases 2. Since the inner rod mounting base 2 is preferably made of plastic, the main handle connection tube 62 is integrally injection molded on the inner rod mounting base 2. A main handle connection rod 63 is fixedly provided on the main rod handle 6. The main handle connection rod 63 is inserted into the two main handle connection tubes 62. A main rod end cap 13 near the main rod handle 6 is provided with a main handle clearance opening 64 corresponding to the main handle connection rod 63.

[0033] Thus, the main handle connecting rod 63 forms a telescopic structure on the main flagpole 1. When not in use, it can be retracted into the main flagpole 1, reducing the overall length of this embodiment. When in use, it can be pulled out to extend its length, facilitating the raising of the flag 4 for display. Based on this, the secondary flagpole 7 is also preferably configured as a telescopic structure, which can be achieved by fitting a single rod tube together. This is a common technical means in the prior art, well known to those skilled in the art, and will not be described in detail here or illustrated in the figures.

[0034] Preferably, the inner ends of the two main handle connecting tubes 62 form a Z-shaped fit to improve the overall integrity of the two main handle connecting tubes 62. Preferably, the length of the main handle connecting tube 62 closer to the main handle 6 is less than the length of the main handle connecting tube 62 farther from the main handle 6. Thus, after the main handle connecting rod 63 is pulled out to a certain length, it still maintains a connection with the two main handle connecting tubes 62. The bending moment force at the main handle 6 can be transmitted to the two inner rod mounting seats 2 through the two main handle connecting tubes 62, and the main handle 6 and the main flagpole 1 as a whole still maintain good bending resistance.

[0035] In actual installation, two main handle connecting pipes 62 are correspondingly installed on the two inner pole mounting seats 2, and two main handle connecting rods 63 are correspondingly installed on the main pole handle 6, connecting the two rods. This further improves the overall bending resistance of the main pole handle 6 and the main flagpole 1, while also increasing the non-rotatability of the main pole handle 6 relative to the main flagpole 1 in the circumferential direction. At this time, the two sets of main handle connecting pipes 62 and the two inner flagpoles 3 form a cross arrangement within the main pole body 11, making full use of the space within the main pole body 11 and improving the structural compactness.

[0036] In this embodiment, during assembly, the flag 4 is first wound around the corresponding inner flagpole 3. One end of each of the two inner flagpoles 3 is pre-installed with the two rotating connecting holes 21 on one of the inner flagpole mounting seats 2. The spring springs 5 ​​in the two spring mounting slots 22 on the inner flagpole mounting seat 2 are then connected to the corresponding ends of the inner flagpoles 3. The pre-assembled components are then installed into the main pole body 11 by first inserting the other ends of the two inner flagpoles 3 into the main pole body 11 until the inner flagpole mounting seat 2 is installed in the corresponding end of the main pole body 11. The other inner flagpole mounting seat 2 is then inserted into the other end of the main pole body 11 by aligning the two rotating connecting holes 21 with the two inner flagpoles 3. The installation stops when the end of the inner flagpole 3 extends into its spring mounting slot 22. The main handle connecting tubes 62 on the two inner flagpole mounting seats 2 are then smoothly connected. Finally, the spring spring 5 in the spring mounting slot 22 is connected to the corresponding end of the inner flagpole 3, completing the installation of the inner flagpoles 3. Install the two main pole end caps 13, wherein the main pole end cap 13 with the main handle clearance opening 64 should have the two main handle clearance openings 64 corresponding to the two main handle connection holes 61 respectively. Finally, install the main pole handle 6 by inserting the two main handle connection rods 63 into the two sets of main handle connection holes 61, thus completing the assembly of the main flagpole 1.

[0037] Preferably, the outer end of the flag 4 is provided with a secondary pole connecting sleeve 41 for the secondary flagpole 7 to be inserted, and the secondary pole connecting sleeve 41 is provided with a pre-tightening operating lug 42. After the main flagpole 1 is assembled, the internal pre-tightening operating lug 42 is located through the opening 12 on the main pole body 11, and is pulled out of the opening 12, causing the free end of the flag 4 to extend out of the opening 12. This process will cause the spring 5 to undergo elastic deformation. The secondary flagpole 7 is inserted into the secondary pole connecting sleeve 41. When the secondary flagpole 7 can be restricted at the opening 12, in this embodiment, the flag 4 is in a state with the pre-tightening force of the spring 5, and the secondary flagpole 7 naturally closes at the opening 12.

[0038] In use, the flag 4 can be pulled directly by operating the secondary flagpole 7. Maintaining the pulling force after pulling will display the content on the flag 4. After releasing the pulling force, the flag 4 is automatically wound back onto the inner flagpole 3 under the spring force of the spring spring 5, making unfolding and folding quick and convenient. This embodiment uses one main flagpole 1 and two secondary flagpoles 7 to install two flags 4, achieving a high degree of integration. Preferably, the content on the two sides of the same flag 4 is different, thus the two flags 4 can display four different contents. This embodiment integrates the existing four flags into a single component, which is conveniently standardized into a whole component. Because this whole component is in a state where the three flagpoles are joined together after the flag 4 is folded up, it can be stored by fixing the main flagpole 1. That is, the storage of the existing four flags is achieved by storing one of the above-mentioned whole components. Preferably, as... Figure 9 and Figure 10 As shown, a buckle 8 is fastened to the main flagpole 1, and a belt connecting part 81 is provided on the buckle 8. This embodiment can be directly carried on the belt through the buckle 8, which is very quick and convenient to store and use, and improves the portability.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
