DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following is a further detailed description of the present invention in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] In the description of the embodiments of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the embodiments of the present invention.

[0021] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, an integral connection, or a detachable connection; it can be the internal connection of two components; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0022] See also Figure 1-4 As shown, an embodiment of the present invention is a traction device for cable laying, comprising a base plate 1 , an upper cover 3 and a reel 4 , wherein the upper cover 3 and the reel 4 are both arranged above the base plate 1 .

[0023] A fixing frame 9 is fixedly connected to the top of the base plate 1, and an adjusting frame 11 is symmetrically provided on both sides of the fixing frame 9. The adjusting frame 11 is slidably connected to the top of the base plate 1, and a sliding rod 10 is fixedly connected to the outer wall on both sides of the fixing frame 9. A corresponding sliding hole 12 is opened on the adjusting frame 11 corresponding to the sliding rod 10, and the sliding rod 10 is slidably inserted into the inside of the sliding hole 12. A guide groove 15 is opened through the fixing frame 9 and the adjusting frame 11. The guide groove 15 on the fixing frame 9 and the guide grooves 15 on the two adjusting frames 11 can form a complete circular through hole.

[0024] A through slot 17 is formed on the outer wall of the upper cover 3 corresponding to the guide slot 15 , and a buckle frame 16 is fixedly connected to the inner wall of the upper cover 3 at a position corresponding to the adjustment frame 11 .

[0025] Support rollers 5 are symmetrically arranged on both sides of the bottom of the unwinding roller 4. Both ends of each support roller 5 are fixedly connected to a pin shaft 6. The end of the pin shaft 6 is rotatably sleeved with a fixed block 7. The fixed block 7 is fixedly connected to the bottom plate 1. The support rollers 5 can support the unwinding roller 4, so that the unwinding roller 4 can rotate more smoothly when unwinding or rewinding.

[0026] One end of the top of the base plate 1 and the inner wall of one side of the upper cover 3 are fixedly connected with blocks 8 corresponding to the two ends of the unwinding roller 4. The two blocks 8 are movably connected to the two ends of the unwinding roller 4 respectively. The setting of the block 8 can effectively make the unwinding roller 4 more stable when it is above the base plate 1 and located inside the upper cover 3.

[0027] The top of the bottom plate 1 is fixedly connected to a support frame 2 , and the upper cover 3 is slidably connected to the support frame 2 . The upper cover 3 can be slidably adjusted above the bottom plate 1 .

[0028] The sliding rod 10 is located between the fixing frame 9 and the adjusting frame 11 and is sleeved with a spring 13 on its rod wall, and grooves 14 are provided on the side walls of the fixing frame 9 and the adjusting frame 11 close to the spring 13. The two ends of the spring 13 are respectively located inside the two adjacent grooves 14. The elastic force of the spring 13 can push the adjusting frame 11 to reset, and the grooves 14 provided can accommodate the compressed spring 13, which can effectively prevent the spring 13 from affecting the fit between the adjusting frame 11 and the fixing frame 9.

[0029] When using the embodiment of the utility model, the adjusting frame 11 above the base plate 1 is moved away from the fixing frame 9 under the elastic force of the spring 13, so that the guide groove 15 on the fixing frame 9 is in an open state. At this time, the unwinding roller 4 is placed between the two support rollers 5 and above the two support rollers 5, and the end of the cable spirally wound on the unwinding roller 4 is stretched and passed through the guide groove 15 on the fixing frame 9, and then the upper cover 3 is moved downward along the support frame 2. When the upper cover 3 is closed to the base plate 1, the buckle frame 16 on its inner wall can push the inclined surface of the adjusting frame 11 through its inclined surface to make the adjusting frame 11 fit toward the fixing frame 9, so that the cable is located in the complete guide groove 15 and is limited. At this time, the end of the cable will pass through the through groove 17. During the process of pulling and unwinding the cable, it will be pulled out along the guide groove 15 and the through groove 17.

[0030] The above shows and describes the basic principles of the present invention. The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. The above embodiments and descriptions in the specification are only to illustrate the principles of the present invention. Without departing from the scope of the present invention, any modifications, equivalent substitutions and improvements made within the spirit and scope of the present invention should be included in the scope of protection of the present invention.
