Description

Technical Field

[0001] The utility model belongs to the field of manual tools, and in particular relates to a telescopic support rod. Background Art

[0002] Workshops usually use overhead cranes and wire ropes to lift heavy objects. Cabin products are large in size, and the lifting rings of some cabins are set on the base. When lifting at the four corners, the wire ropes are easily scratched against the upper edge or other side parts of the cabin, causing paint loss and scratches on the appearance, affecting product shipment. Therefore, struts are added between the wire ropes to widen the angle between the wire ropes and prevent the wire ropes from scratching the products. The existing struts are only straight rods with waist grooves processed at both ends, and the structure is simple.

[0003] Since the cabins have different specifications, the lengths of the struts are also different. Currently, the commonly used specifications are 2m and 4m struts. The struts and wire ropes are only connected with tape. It is time-consuming and laborious to remove the ring each time, and it is not convenient to adjust the height of the struts. Therefore, a strut with optimized structure is needed to make the replacement of the struts more convenient. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a telescopic support pole, the length of which can be freely adjusted to meet the needs of different scenarios. Support poles of various specifications are combined into one, the number of support poles is simplified, and there is no need to frequently replace the support poles.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A telescopic support rod comprises an inner tube and two outer tubes, a handle is fixedly provided at the middle position of the outer side of the inner tube, the two outer tubes are respectively sleeved on the two ends of the inner tube, the outer end of each outer tube is provided with a waist groove and a first bolt hole for a steel wire rope to pass through, after the steel wire rope enters the waist groove, it is fixed by a fixing bolt in the first bolt hole; a plurality of second bolt holes are evenly distributed on the outer tube, and inner tube bolt holes corresponding to the second bolt holes of the outer tube are also provided on the inner tube.

[0007] Furthermore, a plurality of pads are fixedly provided on the outside of the inner tube corresponding to the inner tube bolt holes, and holes corresponding to the inner tube bolt holes are formed on the pads.

[0008] Furthermore, the pad is an annular structure and is fixedly sleeved on the inner tube.

[0009] Furthermore, the inner tube and the outer tube are round tubes or square tubes, and the shape of the pad changes with the shapes of the inner tube and the outer tube.

[0010] Furthermore, the inner tube is a solid tube.

[0011] Furthermore, the upper and lower ends of the wire rope are provided with wire rope clamps, which include a fixing seat and a U-shaped bolt. Both ends of the U-shaped bolt pass through the fixing seat and are locked with nuts. Four claws are evenly protruded circumferentially on the fixing seat, and the U-shaped bolt fixes the wire rope between the claws.

[0012] The beneficial effects of the utility model are: 1. Compared with ordinary support poles, it has a retractable function, and support poles of various specifications are integrated into one, which simplifies the number of support poles and eliminates the need to frequently replace the support poles; 2. When used in combination with a wire rope clamp, it prevents the support pole from sliding up and down or the wire rope from falling off the support pole, avoiding the problem of unreliable fixing by tape winding and troublesome disassembly.

[0017] The following is a clear and complete description of the technical solutions in the embodiments of the utility model in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] The telescopic support rod of the utility model comprises an inner tube 1 and two outer tubes 2. A handle 3 is fixedly provided at the middle position of the outer side of the inner tube 1. The two outer tubes 2 are respectively sleeved on the two ends of the inner tube 1. A waist groove 5 and a first bolt hole 11 for a steel wire rope to pass through are provided at the outer end of each outer tube 2. After the steel wire rope 4 enters the waist groove 5, it is fixed by a fixing bolt in the first bolt hole 11. A plurality of second bolt holes 12 are evenly distributed on the outer tube 2. The inner tube 1 is also provided with inner tube bolt holes 13 corresponding to the second bolt holes 12 of the outer tube 2. When the support rod needs to be extended, the outer tube 2 is slid to both ends by grasping the handle 3. After sliding to the required position, the second bolt hole 12 is aligned with the inner tube bolt hole 13, and the outer tube 2 is fixed to the inner tube 1 by fixing bolts.

[0020] A plurality of pads 6 are fixedly provided on the outside of the inner tube 1 corresponding to the inner tube bolt holes 13. The pads 6 are provided with holes corresponding to the inner tube bolt holes 13. The pads 6 are preferably annular structures and are fixedly sleeved on the inner tube 1. This embodiment does not limit the shapes of the inner tube 1 and the outer tube 2. Round tubes or square tubes can achieve the above functions. Round tubes are easy to manufacture, and square tubes are easy to groove and punch. The shape of the pads 6 changes with the shapes of the inner tube 1 and the outer tube 2. The inner tube 1 can be a solid tube to strengthen the resistance to the reaction force of the wire rope.

[0021] The upper and lower ends of the wire rope 4 are provided with a wire rope clamp 7, which includes a fixing seat 8 and a U-shaped bolt 9. Both ends of the U-shaped bolt 9 pass through the fixing seat 8 and are locked. Four buckle claws 10 are evenly protruded circumferentially on the fixing seat 8, and the U-shaped bolt 9 fixes the wire rope 4 between the buckle claws 10.

[0022] When in use, the steel wire rope 4 enters the waist groove 5, and the fixing bolt in the first bolt hole 11 is locked to fix the steel wire rope 4 in the waist groove 5. Grab the handle 3 to slide the outer tube 2 to the required positions at both ends, align the inner tube bolt hole 13 on the inner tube 1 with the second bolt hole 12 on the outer tube 2, and lock the fixing bolt to fix the inner tube 1 and the outer tube 2 together. In order to prevent the support rod from sliding up and down on the steel wire rope 4, four steel wire rope clips 7 are fixed on the steel wire rope 4, two of which are located above the support rod and two are located below the support rod. Both ends of the U-bolt 9 pass through the fixing seat 8 and are locked to fix the steel wire rope 4 between the four buckle claws 10.

[0023] The retractable support rod is used in combination with the wire rope clamp to simplify the number of support rods, eliminating the need for frequent replacement of support rods. At the same time, it prevents the support rod from sliding up and down or the wire rope from falling off the support rod, avoiding the problem of unreliable fixation due to tape winding and troublesome disassembly.
