Description

Technical Field

[0001] This utility model relates to the field of flag technology, and more specifically, to a quick-install flag hanging crossbar. Background Technology

[0002] Knife flags are a common type of outdoor advertising product, named for their blade-like shape. They are mainly used for exhibitions, promotional activities, and other occasions. Originally designed to be blade-shaped, modern knife flags are mostly square, losing the traditional blade-shaped features. When used on beaches or grass, knife flags are inserted into the ground with stakes. When used on concrete surfaces, they are accompanied by a cross base, water bags, or sandbags.

[0003] A flagpole consists of a flagpole and a flag, but some existing flagpoles are not convenient to disassemble and install quickly, which causes some inconvenience during use.

[0004] Therefore, a quick-installation banner hanging crossbar is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a quick-installation flag hanging crossbar to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-installation flag hanging crossbar, comprising a base, a connecting sleeve fixedly welded to the top of the base, a first flagpole internally threadedly connected to the connecting sleeve, a fixed seat fixedly disposed at the top of the first flagpole, a second flagpole inserted into the fixed seat, two symmetrical mounting grooves symmetrically opened inside the end of the second flagpole near the fixed seat, a compression spring fixedly disposed in each of the two mounting grooves, a locking block fixedly connected to one end of the compression spring and located in each of the two mounting grooves, two locking slots symmetrically through the fixed seat and inserted into the locking blocks, a compression assembly for pressing the two locking blocks provided on the outer wall of the fixed seat, a crossbar body disposed above the end of the second flagpole away from the fixed seat, and a spring locking assembly disposed between the second flagpole and the crossbar body.

[0007] Preferably, the extrusion assembly includes a connecting ring and pressing blocks. The connecting ring is fixedly disposed on the outer side of the fixed base. Two pressing blocks are symmetrically fixedly connected to the inner sidewall of the connecting ring. One end of each pressing block is disposed in one of two slots, and one end of each pressing block abuts against one end of each of the two slots.

[0008] Preferably, the spring locking assembly includes a fixing plate, a connecting seat, a buckle, a connecting block, a pull spring, and a stop block. The fixing plate is bolted to the top of the second flagpole. Two connecting seats are welded to the fixing plate. Two buckles are rotatably connected between the two connecting seats. A connecting block is welded to the outer wall of each of the two buckles. A pull spring is fixedly installed between the bottom wall of the two connecting blocks and the upper surface of the fixing plate. Several sets of stop blocks are provided at one end of the crossbar body, and the crossbar body is fastened between two buckles.

[0009] Preferably, each group of blocks contains two blocks, and a rubber sheet is fixedly disposed on the opposite surface of each of the two blocks.

[0010] Preferably, the outer side of the bottom end of the first flagpole is provided with an external thread, and the inner side wall of the connecting sleeve is provided with an internal thread that engages with the thread of the outer side wall of the first flagpole.

[0011] Preferably, the first flagpole, the second flagpole, and the crossbar body are each provided with multiple fixing rings at equal intervals on their outer side walls, and hooks are fixedly provided on the outer side walls of the fixing rings.

[0012] Preferably, one end of the card block has a connecting groove that is fixedly connected to one end of the compression spring, and the outer side wall of the other end of the card block has an inclined surface.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. Compared with the prior art, when using the device, one end of the second flagpole can be inserted into the fixed seat at the top of the first flagpole. At this time, the two locking blocks are first squeezed. When the two locking blocks move to the slot position opened on the side wall of the fixed seat, the compression spring connected to one end of the locking block will squeeze the locking block, thereby making the locking block insert into the slot, thus completing the quick installation of the first flagpole and the second flagpole. At the same time, the two pressing blocks on the connecting ring can squeeze the two locking blocks, so that the two locking blocks are retracted into the installation slot opened on the second flagpole, which facilitates the subsequent separation of the first flagpole and the second flagpole.

[0015] 2. Compared with the existing technology, the two connecting blocks and the pull spring are used to achieve a closed connection of the buckle. The two closed buckles lock one end of the crossbar body, and the two stops on the outside of the crossbar body can limit the lateral position of the crossbar body. This prevents the crossbar body from moving laterally after it is connected to the second flagpole, thus preventing it from detaching from the second flagpole. This structure can quickly and conveniently achieve the limiting installation and connection of the crossbar body. Attached Figure Description

[0023] Example 1

[0024] As attached Figures 1 to 5 The quick-installation flag-hanging crossbar shown includes a base 1, a connecting sleeve 7 fixedly welded to the top of the base 1, a first flagpole 2 internally threaded to the connecting sleeve 7, an external thread on the outer side of the bottom end of the first flagpole 2, an internal thread on the inner side wall of the connecting sleeve 7 that engages with the thread on the outer side wall of the first flagpole 2, a fixing seat 18 fixedly installed at the top of the first flagpole 2, a second flagpole 3 inserted into the fixing seat 18, two symmetrical mounting slots 15 symmetrically opened inside the end of the second flagpole 3 near the fixing seat 18, a compression spring 16 fixedly installed in each of the two mounting slots 15, a locking block 17 fixedly connected to one end of the compression spring 16 and located in each of the two mounting slots 15, two locking grooves 19 symmetrically opened through the fixing seat 18 that engage with the locking blocks 17, a pressing component for pressing the two locking blocks 17 on the outer side wall of the fixing seat 18, a crossbar body 4 above the end of the second flagpole 3 away from the fixing seat 18, and a spring locking component between the second flagpole 3 and the crossbar body 4.

[0025] In use, the device can first screw the first flagpole 2 to the connecting sleeve 7 to install the first flagpole 2 on the top of the base 1. Then, insert one end of the second flagpole 3 into the fixed seat 18 at the top of the first flagpole 2. At this time, the two locking blocks 17 are first squeezed. When the two locking blocks 17 move to the position of the locking groove 19 opened on the side wall of the fixed seat 18, the compression spring 16 connected to one end of the locking block 17 will squeeze the locking block 17, thereby making the locking block 17 insert into the locking groove 19, thus completing the quick installation of the first flagpole 2 and the second flagpole 3. At the same time, multiple sets of stops 13 are provided on the outer side wall of one end of the crossbar body 4, which can be used to connect flags of different widths.

[0026] Example 2

[0027] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details:

[0028] In a preferred embodiment, the compression assembly includes a connecting ring 20 and pressing blocks 21. The connecting ring 20 is fixedly disposed on the outer side of the fixing base 18. Two pressing blocks 21 are symmetrically fixedly connected to the inner sidewall of the connecting ring 20, and one end of each pressing block 21 is disposed in one of the two slots 19, and one end of each pressing block 21 is in contact with one end of each of the two locking blocks 17. Furthermore, the two pressing blocks 21 disposed on the connecting ring 20 can compress the two locking blocks 17, causing the two locking blocks 17 to retract into the mounting slots 15 opened on the second flagpole 3, thus facilitating the subsequent separation of the first flagpole 2 and the second flagpole 3.

[0029] In a preferred embodiment, the spring locking assembly includes a fixing plate 8, a connecting seat 9, a buckle 10, a connecting block 11, a pull spring 12, and a stop block 13. The fixing plate 8 is bolted to the top of the second flagpole 3. Two connecting seats 9 are welded to the fixing plate 8. Two buckles 10 are rotatably connected between the two connecting seats 9. A connecting block 11 is welded to the outer wall of each of the two buckles 10. A pull spring 12 is fixedly installed between the bottom wall of the two connecting blocks 11 and the upper surface of the fixing plate 8. Several sets of stop blocks 13 are provided at one end of the crossbar body 4, and the crossbar body 4 is fastened between two buckles 10. Each set of stop blocks 13 contains two stop blocks 13, and a rubber sheet 14 is fixedly installed on the opposite surface of each of the two stop blocks 13. Further, when... When the crossbar body 4 is installed at the top of the second flagpole 3, the crossbar body 4 can be pressed first. At this time, the two buckles 10 will rotate and open. Then, after the crossbar body 4 is fully engaged between the two buckles 10, the spring 12 is pulled to squeeze the connecting block 11, which in turn causes the two connecting blocks 11 to drive the buckles 10 to close and return to their original positions. The two closed buckles 10 hold one end of the crossbar body 4 in place. At the same time, the two stops 13 on the outside of the crossbar body 4 can limit the lateral position of the crossbar body 4, preventing the crossbar body 4 from easily moving laterally after it is connected to the second flagpole 3, thus detaching from the connection with the second flagpole 3. This structure can quickly and conveniently achieve the limiting installation and connection of the crossbar body 4.

[0030] In a preferred embodiment, multiple fixing rings 5 ​​are provided at equal intervals on the outer walls of the first flagpole 2, the second flagpole 3, and the crossbar body 4, and hooks 6 are fixedly provided on the outer walls of the fixing rings 5; furthermore, in use, the flag can be installed and connected by hooking the hooks 6 provided on the outer sides of the multiple fixing rings 5 ​​with the connection holes reserved at the edge of the flag.

[0031] The working process of this utility model is as follows: First, the first flagpole 2 is screwed and connected to the connecting sleeve 7, thereby installing the first flagpole 2 on the top of the base 1. Then, one end of the second flagpole 3 is inserted into the fixed seat 18 at the top of the first flagpole 2. At this time, the two locking blocks 17 are first squeezed. When the two locking blocks 17 move to the position of the locking groove 19 opened on the side wall of the fixed seat 18, the compression spring 16 connected to one end of the locking block 17 will squeeze the locking block 17, thereby making the locking block 17 inserted into the locking groove 19, thus completing the quick installation of the first flagpole 2 and the second flagpole 3. At the same time, multiple sets of stop blocks 13 are provided on the outer side wall of one end of the crossbar body 4, which can be used to connect flags of different widths. When disassembling the first flagpole 2 and the second flagpole 3, the two pressing blocks 21 provided on the connecting ring 20 can squeeze the two locking blocks 17, so that the two locking blocks 17 are retracted into the installation groove 15 opened on the second flagpole 3, which facilitates the subsequent separation of the first flagpole 2 and the second flagpole 3.

[0032] When the crossbar body 4 needs to be installed at the top of the second flagpole 3, the crossbar body 4 can be pressed first. At this time, the two buckles 10 will rotate and open. Then, after the crossbar body 4 is fully engaged between the two buckles 10, the spring 12 is pulled to squeeze the connecting block 11, which causes the two connecting blocks 11 to drive the buckles 10 to close and return to their original positions. The two closed buckles 10 hold one end of the crossbar body 4 in place. At the same time, the two stops 13 on the outside of the crossbar body 4 can limit the lateral position of the crossbar body 4, preventing the crossbar body 4 from easily moving laterally after it is connected to the second flagpole 3, thus detaching from the connection with the second flagpole 3. This structure can quickly and conveniently achieve the limited installation and connection of the crossbar body 4. The above is the working principle of this quick-installation flag hanging crossbar.
