[0025] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0026] like Figure 1 and Figure 2 As shown, this utility model describes a connector for connecting side-by-side roll-up banners. The roll-up banner serves as a vertical display stand for displaying posters, advertisements, etc. The roll-up banner body 100 has a storage space for placing the canvas and a canvas outlet 200 connecting the storage space. Both ends of the roll-up banner body 100 are provided with feet 400 for stable support so that the roll-up banner can stand upright and display information. The roll-up banner connector is used to connect two roll-up banner bodies 100 side by side to expand the display area. Moreover, multiple roll-up banner bodies 100 connected side by side in sequence can form a more impressive display combination.

[0027] Specifically, the roll-up banner connector includes a first connecting part 1 and a second connecting part 2 that are interlocked. The opposite end faces of the first connecting part 1 and the second connecting part 2 have an interlocking groove 3 and an interlocking connector 4 protruding from the interlocking groove 3. After the interlocking groove 3 and the interlocking connector 4 are interlocked by an interference fit, two notches 5 are formed between the first connecting part 1 and the second connecting part 2. The bottom feet 400 at the ends of the two connected roll-up banner bodies 100 are respectively located in these two notches 5.

[0028] The insertion direction of the first connecting part 1 and the second connecting part 2 is perpendicular to the axial direction of the roll-up banner.

[0029] In this embodiment, the plug-in connector 4 is distributed in a sheet-like manner in the middle of the second connecting part 2. The sheet-like distribution of the plug-in connector 4 can form a large contact area in the plug-in groove 3 to improve the stability of the connection.

[0030] Furthermore, the upper and lower surfaces of the plug-in connector 4 are provided with protrusions extending along the plugging direction. The protrusions are elongated arcs to facilitate plugging and form an interference fit with the plugging groove 3.

[0031] Furthermore, in order to ensure a firm connection between the first connecting part 1 and the second connecting part 2, guarantee the stability and reliability of the connection, and prevent the connector 4 from accidentally coming out under force, in this embodiment, a traction device 6 is provided between the first connecting part 1 and the second connecting part 2. The traction device 6 includes a traction spring. Under the elastic reset action of the traction spring, the connector block is tightly fitted into the insertion groove 3 of the first connecting part 1.

[0032] Specifically, such as Figure 3 and Figure 4 The first connecting part 1 is further provided with a guide groove 11, which is opened along an axial direction parallel to the insertion direction. The second connecting part 2 is provided with a guide rod 21 slidably connected to the guide groove 11, and the axial direction of the guide rod 21 is consistent with the insertion direction. The traction spring is disposed in the guide groove 11, with one end abutting and fixed in the countersunk hole of the guide groove 11 near the second connecting part 2, and the other end of the traction spring freely extending and retracting with the sliding of the guide rod 21. When an external force is applied to disassemble the first connecting part 1 and the second connecting part 2, the traction spring moves with the guide rod 21 and is in a compressed state. This elastic force causes the guide rod 21 to pull the second connecting part 2 toward the first connecting part 1, forming resistance to the continued disassembly of the first connecting part 1 and the second connecting part 2.

[0033] Furthermore, the free end of the guide rod 21 is limited by a limiting member to restrict the traction spring. In this embodiment, the limiting member is a screw, the end face of the guide rod 21 is provided with a countersunk hole, the screw is threaded into the countersunk hole, and the washer of the screw forms a stop for the traction spring at the free end of the guide rod 21.

[0034] Furthermore, the traction device 6 is provided in two sets, with the two sets of traction devices 6 respectively located at both ends of the roll-up banner connector along the axial direction of the roll-up banner body 100.

[0035] Furthermore, the bottom of the roll-up banner connector and the bottom of the base 400 are located on the same horizontal plane to more stably support the two connected roll-up banners.

[0036] In this embodiment, the roll-up banner body 100 is cylindrical. Grooves 300 extending circumferentially are provided on both sides of the roll-up banner body 100, forming fastening edges for the base 400 to engage. The base 400 is trapezoidal, with its wider base surface contacting the ground and its narrower top surface forming a concave arc and fitting against the roll-up banner body 100. The inclined surface of the trapezoidal base 400 is used to engage in the grooves 300.

[0037] Furthermore, the notch 5 is adapted to the trapezoidal base 400, that is, the inner wall of the notch 5 and the circumferential side of the trapezoidal base 400 are tightly fitted in all directions, making the connection between the two roll-up banner bodies 100 more secure and preventing separation and loosening.

[0038] Furthermore, the end face of the connector opposite to the roll-up banner body 100 is also concave. When the connector is installed in place, the concave surface can also fit tightly against the roll-up banner body 100, further increasing the stability of the connection. Moreover, the entire structure is more harmonious and unified, further enhancing the overall aesthetics of the roll-up banner.

[0039] Furthermore, such as Figure 5 The concave arc surface between the two notches 5 along the axial direction is not continuous, but is instead provided as several reinforcing ribs 7 extending along the insertion direction to improve the overall mechanical strength of the connector. This reinforcing rib 7 structure can reduce the amount of material used and the weight of the connector while ensuring connection stability.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
