[0033] As shown in FIG. Figures 1 to 3 A line fastening structure against falling off includes a fastener body 1, which is detachably connected to an LED display device 3 through a connecting piece 2.

[0034] The fastener body 1 is provided with a clamping through slot 11 penetrating along the length direction thereof, a wire 4 is inserted and clamped in the clamping through slot 11, and the leading end of the wire 4 extends out of the clamping through slot 11 and is electrically connected with the LED display device 3.

[0035] The wire 4 of the present solution can be a Type-C signal line, which is an important signal connection between a control device case and an LED display screen in the LED display device 3. The prior art usually directly uses the Type-C signal line repeatedly by plugging and unplugging, and the interface of the control device case is prone to loosening after a period of time or after moving position, and the Type-C signal line is easy to fall off. Therefore, the fastener body 1 needs to be added on the shell, which not only ensures the stable connection of the Type-C signal line under various conditions, but also makes the installation of the entire structure very convenient, easy to maintain, and applicable to different specifications and types of LED display devices 3.

[0036] Specifically, the anti-falling wire fastening structure mainly comprises a fastener body 1, the fastener body 1 is provided with a clamping through slot 11, the wire 4 is inserted into the clamping through slot 11 and electrically connected with the LED display device 3, since the clamping through slot 11 is arranged along the length direction of the fastener body 1, the contact area of the wire 4 and the clamping through slot 11 is large, when the fastener body 1 is fixed on the case shell of the LED display device 3 through the connecting piece 2, the fastener body 1 and the wire 4 are not easy to fall off. The case shell of the LED display device 3 is usually formed by bending a sheet metal part, and the interface of the Type-C signal line is reserved on the shell for installation and plugging, and the shell is also provided with locking tooth holes for facilitating the fixation of the connecting piece 2. The above structure solves the problem of easy loosening and falling off of the wire 4 fixing device in the prior art, and has the advantages of simple overall structure, quick and convenient installation and disassembly, and no need to use special tools.

[0037] Further, the top end of the fastener body 1 extends horizontally to form two fixing ears 12 on both sides, respectively, and mounting holes 121 are formed in the two fixing ears 12, respectively, and the two connecting pieces 2 are inserted into the corresponding mounting holes 121 and detachably connected with the LED display device 3.

[0038] Since the Type-C signal line needs to be repeatedly plugged and unplugged, the fastener body 1 will be subjected to a large external force pulling each time, in order to more stably fix the fastener body 1 on the case shell of the LED display device 3, the fixing ears 12 are arranged on both sides of the fastener body 1, the two fixing ears 12 are fixed by the two connecting pieces 2, respectively, the fastener body 1 can be evenly dispersed when subjected to external force, so that the fastener body 1 and the internal Type-C signal line are not easy to fall off.

[0039] Further, one side of the fastener body 1 is also provided with a clamping entrance 13 for placing the wire 4, the clamping entrance 13 is communicated with the clamping through slot 11, and the clamping entrance 13 penetrates along the length direction of the fastener body 1.

[0040] In order to conveniently clamp the Type-C signal line into the clamping through slot 11, the clamping entrance 13 is arranged on one side of the fastener body 1, generally, the interface end of the Type-C signal line is an oval in cross section, and a long cylindrical wire is connected with the interface end, the size of the clamping entrance 13 is usually smaller than the size of the long side of the Type-C signal line, when the Type-C signal line is clamped, the wire is placed in the clamping through slot 11, and then pulled down tightly, so that the interface end of the Type-C signal line is tightly clamped in the clamping through slot 11.

[0041] Further, the clamping through slot 11 comprises a first clamping section 111 and a second clamping section 112 connected in sequence, the inner diameter of the first clamping section 111 is greater than the inner diameter of the second clamping section 112, so that a limiting step 113 is formed at the connection of the first clamping section 111 and the second clamping section 112, and the limiting step 113 is used to abut against the edge of the wire 4.

[0042] The clamping through slot 11 is divided into a first clamping section 111 and a second clamping section 112, wherein the size of the top end of the first clamping section 111 matches the interface end gap of the Type-C signal line, so that the top end of the first clamping section 111 plays a guiding role, and the remaining part of the first clamping section 111 mainly plays a fastening role, and is in interference fit with the size of the Type-C signal line interface end shell, so as to quickly fix the Type-C signal line on the fastener body 1; the second clamping section 112 plays a role of paying off wire, and is used for the wire at the tail of the Type-C signal line to pass through. When the Type-C signal line is installed on the fastener body 1, first hold the tail of the Type-C signal line and place it in the second clamping section 112, then pull down to place the interface end of the Type-C signal line in the first clamping section 111, because the connection of the two is provided with a limiting step 113, and when the interface end shell of the Type-C signal line is abutted against the limiting step 113, the fastening of the wire 4 is completed.

[0043] Through the above-mentioned unique locking structure, not only the stable connection of the wire 4 under various conditions can be ensured, but also the installation and maintenance are facilitated.

[0044] Further, the first side wall 1111 on both sides of the first clamping section 111 is arc-shaped; and the second side wall 1121 on both sides of the second clamping section 112 is arc-shaped. Because the shell of the interface end of the Type-C signal line is in the shape of an elliptical cylinder, and the wire at the tail of the Type-C signal line is in the shape of a cylinder, designing the first side wall 1111 and the second side wall 1121 as arc-shaped can better fit the various sections of the Type-C signal line closely, so that the clamping effect of the wire 4 is better.

[0045] Further, the upper end and the lower end of the second side wall 1121 respectively extend outward to form vertical elongated sections 114. The setting of the elongated sections 114 makes the accommodation space of the second clamping section 112 become larger, and the compatibility is stronger, and multiple specifications of the wire 4 are supported to be fixed.

[0046] Further, the connecting piece 2 comprises a screw cap 21, a light rod 22 and a threaded column 23 connected in sequence, the diameter of the light rod 22 is smaller than the diameter of the threaded column 23, the mounting hole 121 comprises a threaded section 1211 and a smooth through-hole section 1212 connected with each other, when the connecting piece 2 is inserted into the mounting hole 121, the threaded column 23 is screwed into the threaded section 1211, the light rod 22 extends into the through-hole section 1212, and the screw cap 21 abuts against the outer surface of the fixing lug 12.

[0047] In the embodiment, the fastener is fixed on both sides by non-removable screws. The connecting piece 2 (non-removable screw) comprises a screw cap 21, a light rod 22 and a threaded column 23, the screw cap 21 of the connecting piece 2 is of a knurled type, facilitating hand-tightening installation, the length of the threaded column 23 accounts for a small part of the entire connecting piece 2, and the length of the light rod 22 accounts for a part, the diameter of the light rod 22 is smaller than the diameter of the threaded column 23, the connecting piece 2 is installed on the fastener body 1, the threaded section 1211 in the mounting hole 121 is a tooth hole, and the outer side of the tooth hole is further provided with a smooth through-hole section 1212. The threaded column 23 is screwed into the threaded section 1211, the light rod 22 extends into the through-hole, and the screw cap 21 abuts against the outer surface of the fixing lug 12 to form a non-removable screw structure. Finally, the Type-C signal line is inserted into the connecting port of the case shell of the LED display device 3, and when the Type-C signal line is inserted into position, there is a gap of 1-2 mm between the shell of the interface end of the Type-C signal line and the device shell. At this time, the threaded column 23 is screwed into the hole position on the case shell of the LED display device 3 and is directly locked to the case shell of the LED display device 3, and the phenomenon of loosening does not occur. When it is necessary to remove the Type-C signal line, the connecting piece 2 is loosened first, and the plugging and unplugging can be completed.

[0048] Further, each corner of the fastener body 1 is a rounded corner. The corners of the fastener body 1 are all rounded, facilitating the clenching of the operator and being safer.

[0049] Further, the fastener body 1 is made of aluminum. The fastener body 1 is precisely processed from a high-strength aluminum block, and has the characteristics of good protection performance, corrosion resistance, aging resistance and long service life.
