DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1-5 As shown, an engineering plastic drag chain structure that is easy to connect includes an engineering plastic link 100, and the engineering plastic link 100 includes two side plates 101. The two side plates 101 are close to each other and have an internal groove 102. The two side plates 101 are far away from each other and have an external groove 103. Two connecting plates 104 are fixedly connected to one side of the end of the two side plates 101 close to each other corresponding to the internal groove 102;

[0028] The two inner grooves 102 are each provided with a clamping groove 1021 at one end close to each other;

[0029] The two external grooves 103 are each provided with a telescopic groove 1031 at one end away from each other, and the inner walls of the two telescopic grooves 1031 are fixedly connected with multiple springs 1032, and the multiple springs 1032 are each fixedly connected with a clamping column 1033 at one end away from each other. The inner sides of the corresponding springs 1032 at one end close to each other of the two clamping columns 1033 are respectively fixedly connected with a telescopic sleeve 1034 and a telescopic column 1035 and penetrate the side plate 101, and the telescopic column 1035 is arranged on the inner wall of the telescopic sleeve 1034.

[0030] In this embodiment, a support column 1041 is provided between the two connecting plates 104, and both sides of one end of the support column 1041 close to the telescopic sleeve 1034 and the telescopic column 1035 are fixedly connected to the limiting plates 1042, and the other ends of the two limiting plates 1042 are provided with arc-shaped notches 1043, and the inner walls of the two arc-shaped notches 1043 are fixedly connected with arc-shaped rods 1044, and the outer walls of the telescopic sleeve 1034 and the telescopic column 1035 are provided with annular grooves 1045, and the two annular grooves 1045 and the arc-shaped rods 1044 are adapted in shape;

[0031] When installing the support column 1041, the arc rod 1044 can be stuck in the annular groove 1045 to limit the telescopic sleeve 1034 and the telescopic column 1035, prevent the telescopic sleeve 1034 and the telescopic column 1035 from shaking freely, and avoid the separation of the two engineering plastic chain links 100, thereby avoiding affecting the use and preventing the telescopic sleeve 1034 and the telescopic column 1035 from rotating.

[0032] In this embodiment, the support column 1041 has a limiting groove 1046 at one end close to the connecting plate 104, and the inner walls of the two limiting grooves 1046 are provided with limiting columns 1047, and the two limiting columns 1047 are fixedly connected to the connecting plate 104;

[0033] The support column 1041 can be limited by the cooperation of the limiting groove 1046 and the limiting column 1047 , so that the arc rod 1044 can be quickly inserted into the annular groove 1045 .

[0034] In this embodiment, the ends of the two connecting plates 104 close to the inner groove 102 are rotatably connected to the blocking rods 1048, the ends of the two blocking rods 1048 close to the limiting pillars 1047 are fixedly connected to the first magnets 1049, and the ends of the support pillars 1041 close to the inner groove 102 are fixedly connected to the second magnets 10410 on both sides, and the two second magnets 10410 and the first magnet 1049 have different magnetic properties;

[0035] By the mutual adsorption of the second magnet 10410 and the first magnet 1049 , the blocking rod 1048 can be limited, thereby completing the limiting and fixing of the support column 1041 .

[0036] In this embodiment, the two clamping columns 1033 are arranged at ends away from each other and are configured as inclined surfaces, and the two clamping columns 1033 are arranged inside the clamping slot 1021;

[0037] The inclined surface is provided to facilitate the contraction of the clamping column 1033 into the telescopic slot 1031 . After the connection is completed, the clamping column 1033 is clamped into the clamping slot 1021 .

[0038] It should be noted that the utility model is an engineering plastic drag chain structure that is convenient to connect. When in use, the inner groove 102 is first clamped in the outer groove 103. During this process, since one side of the clamping column 1033 is inclined, the clamping column 1033 can be squeezed. When the inner groove 102 and the outer groove 103 are completely clamped together, the clamping column 1033 is clamped into the clamping groove 1021 by the reset effect of the spring 1032, so that the connection of the two engineering plastic chain links 100 can be quickly completed, which is convenient and fast, and improves the connection efficiency.

[0039] When the telescopic sleeve 1034 and the telescopic column 1035 are pulled inward, the clamping column 1033 is moved out of the clamping slot 1021 and the limit is released, so that the two engineering plastic chain links 100 can be separated from each other.

[0040] After the connection is completed, the limiting groove 1046 and the limiting column 1047 are aligned, and the support column 1041 is clamped between the connecting plates 104, and the arc rod 1044 is clamped in the annular groove 1045, so as to limit the telescopic sleeve 1034 and the telescopic column 1035, prevent the telescopic sleeve 1034 and the telescopic column 1035 from moving freely, thereby preventing the engineering plastic chain link 100 from breaking during use, thereby preventing the use from being affected;

[0041] Then, the blocking rod 1048 is rotated to make the first magnet 1049 and the second magnet 10410 adsorb together, thereby completing the limitation of the support column 1041 and preventing the support column 1041 from falling off. In addition, through the setting of the support column 1041, the compressive resistance of the connecting plate 104 can be improved and it can withstand greater torque.

[0042] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
