Description

Technical Field

[0001] The utility model relates to the technical field of cable reel stands, in particular to a cable reel stand with a protection mechanism. Background Art

[0002] The cable reel stand can select a suitable cable reel stand according to the diameter and tonnage of the cable reel.

[0003] At present, an existing cable reel stand (such as patent number: CN207258885U) discloses a cable reel stand, which includes two bases. The top ends of the two bases are fixedly connected to the bottom end of the vertical frame. The middle parts of the top ends of the two bases are fixedly provided with support ends. The support ends are movably connected to one end of the ball screw. The outer wall of the middle part of the ball screw is provided with threads. The two ball screws are movably connected to the two ends of the cable reel rod through two connecting devices. The other end of the ball screw is inserted and connected to the through hole and the fixed end provided at the top end of the vertical frame. The other end of the ball screw is fixedly connected to the bottom end of the turntable. By providing the wheel seat, the utility model can not only facilitate transportation by folding the wheel seat and using the wheels when transporting a single reel stand, but also unfold the wheel seat when using the reel stand to play a role in fixing the base and prevent the reel stand from being toppled due to the excessive weight of the cable reel. By providing the ball screw and the ball nut, it can replace the traditional jack to lift and lower the cable reel rod, saving costs.

[0004] However, in the process of implementing the above technical solution, it is found that there are at least the following problems: the wheel seat plays a role in fixing the base to prevent the reel stand from being toppled due to the excessive weight of the cable reel, playing a protective role. However, the crossbar sleeve and the cable reel rod are only connected by socketing. During the installation process or use process, the socket connection is likely to cause the connection between the crossbar sleeve and the cable reel rod to become loose or disengaged when subjected to impact or vibration, posing a danger to the safety of the staff using or installing the reel stand.

[0023] Embodiment

[0024] As Figure 1 , Figure 2 , Figure 3 and Figure 4, the technical solution in the embodiments of the present application effectively solves the technical problem that socket connection is likely to cause loosening or detachment of the connection between the crossbar sleeve and the cable reel rod when subjected to impact or vibration, posing a danger to the safety of the staff using or installing the cable reel. The general idea is as follows:

[0025] In view of the problems existing in the prior art, the utility model provides a cable reel with a protection mechanism. The cable reel with a protection mechanism includes two brackets 1. A lead screw 2 is rotatably connected to the inner side of each bracket 1. A connecting block 3 is threadedly connected to the outside of each lead screw 2. An installation shaft 4 is arranged between the two connecting blocks 3. Protection mechanisms are arranged at both ends of the installation shaft 4. Each protection mechanism includes an installation groove 5, a threaded hole 6 and a limit screw 7. The installation groove 5 is opened on the outside of the installation shaft 4. The threaded hole 6 is opened on the side of the installation shaft 4 close to the connecting block 3. The threaded hole 6 is internally communicated with the installation groove 5. The limit screw 7 is threadedly connected to the inside of the threaded hole 6. The connecting block 3 is clamped inside the installation groove 5. Limit rings 17 are slidably connected to both ends of the installation shaft 4. Thread grooves 8 are opened on the outside of each limit ring 17. Fixing screws 9 are threadedly connected to the inside of each thread groove 8.

[0026] By setting the limit screw 7 and cooperating with the limit ring 17, when installing the cable reel, the connecting block 3 on one side is clamped inside the installation groove 5. At this time, rotate the limit screw 7 to make the limit screw 7 rotate into the installation groove 5 so that the limit screw 7 closely fits on the outside of the connecting block 3. At this time, one end of the installation shaft 4 is installed. At this time, pull one side of the limit ring 17 to release the connection with the installation shaft 4. At this time, pass the cable reel through the outside of the installation shaft 4. At this time, install the limit ring 17 on the outside of the installation shaft 4 again. At this time, adjust the positions of the two limit rings 17 so that the two limit rings 17 are close to both ends of the cable reel. At the same time, the limit rings 17 limit the left and right movement of the cable reel to avoid the cable reel moving and colliding with the staff. At this time, rotate the fixing screw 9 to make the fixing screw 9 fit on the outside of the connecting block 3. At this time, the position of the limit ring 17 is fixed. At this time, sleeve the other end of the installation shaft 4 on the outside of the connecting block 3, and then rotate the limit screw 7 to make the limit screw 7 fit on the outside of the connecting block 3. At this time, the cable reel is installed. The protection mechanism can improve the connection stability between the installation shaft 4 and the connecting block 3, reduce the probability of loosening or detachment of the connection between the installation shaft 4 and the connecting block 3, and provide a certain guarantee for the safety of the staff.

[0027] On one side of each limit ring 17 away from the fixing screw 9, a protective pad 10 is provided. The protective pad 10 is slidably connected to the outside of the mounting shaft 4. The protective pad 10 reduces the direct contact between the cable reel and the limit ring 17, reduces the wear of the limit ring 17, and extends the service life of the limit ring 17. A clamping groove 11 is formed on the outside of each limit ring 17, and the protective pad 10 is clamped inside the clamping groove 11, which facilitates the disassembly and assembly of the protective pad 10. At both ends of the inside of each clamping groove 11, an internal groove 12 is formed. A clamping plate 13 is slidably connected to the inside of each internal groove 12. The clamping plate 13 is attached to the outside of the protective pad 10 to improve the installation stability of the protective pad 10. Two springs 14 are fixedly connected to the inside of each internal groove 12. The springs 14 are fixedly connected to the outside of the clamping plate 13 to facilitate providing support for the clamping plate 13. Through holes 15 are formed at both ends of each limit ring 17. The through holes 15 communicate with the internal grooves 12. A pull plate 16 is slidably connected to the inside of each through hole 15. The pull plate 16 is fixedly installed on the outside of the clamping plate 13 to facilitate pulling the clamping plate 13. By providing the protective pad 10 and cooperating with the clamping groove 11, when installing the limit ring 17, pull the pull plate 16 to drive the clamping plate 13 to make the clamping plate 13 enter the inside of the internal groove 12. At this time, the spring 14 is compressed. Then slide the protective pad 10 into the inside of the clamping groove 11. Then release the clamping plate 13. Under the action of the spring 14, the clamping plate 13 moves towards the protective pad 10 to clamp and fix both ends of the protective pad 10. At this time, the installation of the protective pad 10 is completed. The protective pad 10 reduces the direct contact between the cable reel and the limit ring 17, reduces the wear of the limit ring 17, and extends the service life of the limit ring 17.

[0028] Working principle:

[0029] First step, by providing the protective pad 10 and cooperating with the clamping groove 11, when installing the limit ring 17, pull the pull plate 16 to drive the clamping plate 13 to make the clamping plate 13 enter the inside of the internal groove 12. At this time, the spring 14 is compressed. Then slide the protective pad 10 into the inside of the clamping groove 11. Then release the clamping plate 13. Under the action of the spring 14, the clamping plate 13 moves towards the protective pad 10 to clamp and fix both ends of the protective pad 10. At this time, the installation of the protective pad 10 is completed. Then slide the limit ring 17 on the outside of the mounting shaft 4. The protective pad 10 reduces the direct contact between the cable reel and the limit ring 17, reduces the wear of the limit ring 17, and extends the service life of the limit ring 17;

[0030] Second step, by setting the limit screw 7 and cooperating with the limit ring 17, when installing the cable reel, snap the connecting block 3 on one side into the installation groove 5. At this time, rotate the limit screw 7 so that the limit screw 7 rotates into the installation groove 5 and closely fits outside the connecting block 3. At this time, one end of the installation shaft 4 is installed. Then, pull the limit ring 17 on one side to release the connection with the installation shaft 4. Then, pass the cable reel through the outside of the installation shaft 4. Then, install the limit ring 17 on the outside of the installation shaft 4 again. At this time, adjust the positions of the two limit rings 17 so that the two limit rings 17 are close to both ends of the cable reel. Then, rotate the fixing screw 9 so that the fixing screw 9 fits outside the connecting block 3. At this time, the position of the limit ring 17 is fixed. Then, sleeved the other end of the installation shaft 4 on the outside of the connecting block 3, and rotate the limit screw 7 again so that the limit screw 7 fits outside the connecting block 3. At this time, the cable reel is installed.

[0031] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
