Description

Technical Field

[0001] This utility model relates to the field of elevator air conditioning cable protection technology, and in particular to an elevator air conditioning cable protection device. Background Technology

[0002] In elevator air conditioning systems, cables play a crucial role in power transmission and signal exchange. Their stable operation directly affects the cooling, heating, ventilation, and other functions of the elevator air conditioning system. With the development of intelligent and comfortable elevators, air conditioning configurations are becoming increasingly common, requiring cables to be installed in the complex environment of the elevator car and shaft for extended periods. However, the frequent vibrations during elevator operation, the relative movement of car and shaft components, and operational interference during routine maintenance all place stringent demands on the physical protection of cables. This has prompted the industry to continuously explore more reliable cable protection solutions to ensure the stability of elevator air conditioning systems and extend cable lifespan.

[0003] Existing elevator air conditioning cable protection structures are mostly fixed-length sleeves or covers, relying on rigid connection structures such as bolts. When the cable needs to be inspected or replaced, the disassembly process is also complicated, reducing the efficiency of cable installation and maintenance. At the same time, the existing protection devices are not effective in fixing the cable. Most devices simply wrap the cable with a sleeve, and there is no effective clamping structure between the sleeve and the cable. When the elevator vibrates during operation, the cable is prone to shaking and displacement inside the sleeve, causing frequent friction between the cable and the inner wall of the sleeve, which will cause wear to the cable. Therefore, an elevator air conditioning cable protection device is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an elevator air conditioning cable protection device, which aims to improve the problems of existing protection devices being inconvenient for cable inspection and replacement and having poor cable fixing effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An elevator air conditioning cable protection device includes a protective shell one, a protective shell two slidably connected to the outer side of the protective shell one, outer rings slidably connected to both ends of the protective shell one and the protective shell two, an outer shell fixedly connected to the outer side of the outer rings, and a fixing component installed inside the outer shell. The fixing component includes a plug rod that is slidably connected inside the housing. A limit ring is fixedly connected to the outside of the plug rod. A spring is installed inside the housing and is sleeved on the outside of the plug rod. As a further description of the above technical solution: A threaded tube is fixedly connected to the outer side of the outer ring, and multiple clamping blocks are fixedly connected to the end of the threaded tube. A threaded sleeve is threadedly connected to the outer side of the threaded tube. As a further description of the above technical solution: The end of the insertion rod is fixedly connected to a rotating shaft, and a rotating handle is rotatably connected to the outside of the rotating shaft; As a further description of the above technical solution: Both the first and second protective shells have locking holes on their outer sides, and the insertion rod is engaged in the middle of the locking hole; As a further description of the above technical solution: A sliding strip is fixedly connected to the outer side of the second protective shell, and the sliding strip is slidably connected to the outer side of the first protective shell; As a further description of the above technical solution: A sliding groove is provided on the outer side of the protective shell, and the sliding strip is slidably connected to the middle of the sliding groove; As a further description of the above technical solution: A cable port is provided on the outer side of the threaded sleeve.

[0006] This utility model has the following beneficial effects: 1. In this utility model, the insert rod is engaged with the locking hole by the spring and the limiting ring, thereby fixing the first protective shell and the second protective shell. Pulling the handle will drive the insert rod to disengage from the locking hole through the rotating shaft, so that the outer ring and the threaded tube can be removed, thereby separating the first protective shell and the second protective shell, which improves the convenience of cable installation and maintenance.

[0007] 2. In this utility model, the first protective shell and the second protective shell are fixed by the outer ring. Then, by rotating the threaded sleeve, the threaded sleeve moves towards the threaded tube, thereby squeezing the clamping block and causing it to contract, so as to clamp the cable inserted into the cable port, prevent the cable from shaking and shifting, and improve the reliability of cable protection.

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of an elevator air conditioning cable protection device, comprising a protective shell 1, a protective shell 2 slidably connected to the outer side of the protective shell 1, the protective shell 1 and the protective shell 2 together forming a protective space to accommodate the cable, providing physical protection for the internal cable, outer rings 5 ​​slidably connected to both ends of the protective shell 1 and the protective shell 2, and a housing 10 fixedly connected to the outer side of the outer rings 5, with a fixing component installed inside the housing 10. The fixing component can fix the outer rings 5 ​​to the outer side of the protective shell 1 and the protective shell 2, maintaining the connection stability of the protective shell 1 and the protective shell 2; the fixing component includes... The device includes a plug rod 11, which is slidably connected inside the housing 10. A limiting ring 12 is fixedly connected to the outside of the plug rod 11. A spring 13 is installed inside the housing 10 and is sleeved on the outside of the plug rod 11. Through the elastic force of the spring 13 and the limiting action of the limiting ring 12, the plug rod 11 will be inserted into the protective shell 1 and the protective shell 2, thereby fixing the outer ring 5 to the outside of the protective shell 1 and the protective shell 2, and fixing the protective shell 1 and the protective shell 2. By retracting the plug rod 11 and releasing its engagement with the protective shell 1 and the protective shell 2, the outer ring 5 can be removed, thereby separating the protective shell 1 and the protective shell 2. Reference Figure 1 , Figure 2 and Figure 4 A threaded tube 3 is fixedly connected to the outer side of the outer ring 5. Multiple clamping blocks 4 are fixedly connected to the end of the threaded tube 3. A threaded sleeve 6 is threadedly connected to the outer side of the threaded tube 3. Rotating the threaded sleeve 6 causes it to move threadedly towards the threaded tube 3. During this process, the threaded sleeve 6 will squeeze the clamping block 4, causing the clamping block 4 to contract inward, thereby clamping the cable inserted therein, thus fixing the cable and preventing it from shaking or shifting. Reference Figures 1-5The end of the insertion rod 11 is fixedly connected to a rotating shaft 14, and a rotating handle 15 is rotatably connected to the outside of the rotating shaft 14. Rotating the rotating handle 15 can drive the insertion rod 11 to retract or extend through the rotating shaft 14, realizing the locking and disengagement of the insertion rod 11. Both the outer sides of the protective shell 1 and the protective shell 2 are provided with locking holes 16. The insertion rod 11 is locked in the middle of the locking hole 16. By cooperating with the locking hole 16, the insertion rod 11 is locked onto the protective shell 1 and the protective shell 2, realizing the locking and disengagement of the protective shell 1 and the protective shell 2. The second protective shell 2 is fixedly connected to the outside of the second protective shell 2. The slide bar 8 is slidably connected to the outside of the first protective shell 1. The outside of the first protective shell 1 is provided with a sliding groove 9. The slide bar 8 is slidably connected to the middle of the sliding groove 9. The slide bar 8 and the sliding groove 9 provide a guiding structure for the sliding connection between the first protective shell 1 and the second protective shell 2, and improve the stability of the connection between the first protective shell 1 and the second protective shell 2. The outside of the threaded sleeve 6 is provided with a cable port 7, which provides a channel for the cable to enter and exit the protective device, and facilitates the cable to be inserted.

[0012] Working principle: The protective shell 1 and the protective shell 2 form the main body of the cable protection, providing physical protection space for the cable and resisting external collisions and friction. The protective shell 2 is slidably connected to the sliding groove 9 on the outside of the protective shell 1 via the sliding strip 8, allowing the two to slide relative to each other, which improves the stability of the connection between the protective shell 1 and the protective shell 2. The spring force of the spring 13 pushes the plug rod 11 into the locking hole 16, thereby fixing the protective shell 1 and the protective shell 2. Pulling the handle 15 drives the plug rod 11 to overcome the spring force of the spring 13 and disengage it from the locking hole 16 through the rotating shaft 14, so that the outer ring 5 and the threaded tube 3 can be removed, thereby separating the protective shell 1 and the protective shell 2, which facilitates the installation and removal of the cable.

[0013] The threaded tube 3 and clamp 4 on the outer side of the outer ring 5 cooperate with the threaded sleeve 6. Rotating the threaded sleeve 6 causes it to move towards the threaded tube 3, thereby squeezing the clamp 4 to contract and clamping the cable that is inserted into the cable port 7. This prevents the cable from shaking and shifting inside the protective device, thus achieving stable protection and fixation of the cable.

[0014] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
