Description

Technical Field

[0001] This utility model relates to the field of cable shaft technology, specifically a splicing type cable shaft. Background Technology

[0002] A cable shaft is a facility used to centrally manage a group of cables along a route, preventing them from becoming tangled or damaged. It facilitates cable repair and replacement and helps maintain the normal operation of the cables. Cable shafts are widely used in the construction industry, such as in large buildings like high-rise residential buildings, commercial complexes, hospitals, and schools, which require a large amount of cable cabling. Cable shafts provide an effective vertical conduit for these cables, preventing them from twisting or bending during cabling and ensuring the safety and stability of the building's cable system.

[0003] In existing cable shaft technology, splicing and fixing are often achieved by welding or bolts. Although welding provides high stability, it is inefficient and becomes more complicated as the shaft increases in height. Similarly, bolt fixing is also inefficient, requiring at least four bolts between each section of the shaft. This method is inefficient, cumbersome, and requires specialized tools. Therefore, an improved splicing type cable shaft is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to provide a splicing type cable shaft to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a splicing type cable shaft, including a housing, with connecting rods fixedly installed at the four corners of the lower surface of the housing, and hanging ears fixedly installed at the lower ends of the connecting rods. A locking mechanism for fixing adjacent housings is provided on the outer surface of the upper end of the housing. The locking mechanism includes a mounting plate, a handle, a latch, and a slot. A mounting plate is fixedly installed on one side of the housing surface. A handle is movably installed on the outer surface of the mounting plate via a pivot. A latch is movably installed on the outer surface of the handle via a pivot. A slot is provided on the surface of the latch.

[0006] Preferably, a limiting member is fixedly provided on the surface of the mounting plate, and a limiting groove is formed on the outer surface of the handle, such as... Figure 4 As shown, after the handle drives the buckle to lock and fix the hanging ear in place using the slot, the limiting component will be inserted into the limiting groove. At this time, the protrusion can prevent the buckle and hanging ear from loosening when the handle is turned without human intervention. When it is necessary to insert the limiting component into the limiting groove, simply turn the handle forcefully to squeeze the limiting component and make it contract towards the center, thereby squeezing the limiting component into the limiting groove.

[0007] Preferably, the limiting member is made of an elastic metal material. When the limiting member is squeezed by the handle, it can contract towards the center, thereby eventually allowing the limiting member to be inserted into the limiting groove.

[0008] Preferably, both sides of the limiting member are fixedly provided with protrusions, which can improve the stability of the limiting member when it locks the handle.

[0009] Preferably, a sealing ring is provided on the outer surface of the upper end of the housing. After two adjacent housings are installed and connected, the sealing ring can be squeezed, and the sealing between the two adjacent housings can be guaranteed by the sealing ring.

[0010] Preferably, the upper surface of the housing has U-shaped notches at the four corners. By passing the connecting rod of the upper housing through the U-shaped notch of the lower housing, the two shafts can be quickly connected together. After the U-shaped notch and the connecting rod are engaged, the relative front-to-back and left-to-right displacement of the two adjacent shafts can be prevented. Then, by locking the lugs with the buckle, the relative vertical displacement of the two adjacent housings can also be prevented, so that the fixing of the two adjacent housings can be completed quickly.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention uses a locking buckle to secure the hanging lugs, preventing any vertical displacement between adjacent housings. This allows for quick and easy fixing of adjacent housings. The use of this quick-locking fixing method for shaft installation is highly efficient and facilitates its widespread adoption.

[0013] When the handle drives the latch to lock, the limiting member will eventually be inserted into the limiting groove. At this time, the protrusion can prevent the latch and the hanging ear from loosening when the handle is rotated without human intervention, thereby improving the fixing stability of the device.

[0019] 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.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a splicing type cable shaft, including a housing 1. Connecting rods 2 are fixedly installed at the four corners of the lower surface of the housing 1. The lower end of the connecting rods 2 is fixedly installed with a hanging lug 3. The upper outer surface of the housing 1 is provided with a locking mechanism for fixing adjacent housings 1. The locking mechanism includes a mounting plate 4, a handle 5, a latch 6, and a slot 7. The mounting plate 4 is fixedly installed on one side of the surface of the housing 1. The handle 5 is movably installed on the outer surface of the mounting plate 4 through a rotating shaft. The latch 6 is movably installed on the outer surface of the handle 5 through a rotating shaft. The slot 7 is opened on the surface of the latch 6.

[0021] A limiting element 8 is fixedly provided on the surface of the mounting plate 4, and a limiting groove 9 is formed on the outer surface of the handle 5, such as... Figure 4 As shown, after the handle 5 drives the buckle 6 to lock and fix the hanging ear 3 using the slot 7, the limiting member 8 will be inserted into the limiting groove 9. At this time, the protrusion 10 can prevent the handle 5 from being turned without human intervention, which would cause the buckle 6 and the hanging ear 3 to loosen. When it is necessary to insert the limiting member 8 into the limiting groove 9, simply turn the handle 5 forcefully to squeeze the limiting member 8 to shrink towards the center, so that the limiting member 8 can be squeezed into the limiting groove 9.

[0022] The limiting member 8 is made of elastic metal material. When the limiting member 8 is squeezed by the handle 5, it can contract towards the center, so that the limiting member 8 can eventually be inserted into the limiting groove 9.

[0023] Both sides of the surface of the limiting member 8 are fixedly provided with protrusions 10, which can improve the stability of the limiting member 8 when it is stuck in the handle 5.

[0024] A sealing ring 11 is provided on the outer surface of the upper end of the housing 1. After two adjacent housings 1 are installed and connected, the sealing ring 11 can be squeezed. At this time, the sealing ring 11 can ensure the sealing between the two adjacent housings 1.

[0025] The upper surface of the housing 1 has U-shaped notches 12 at the four corners. The connecting rod 2 of the upper housing 1 is passed through the U-shaped notch 12 of the lower housing 1, which can quickly connect the two shafts together. After the U-shaped notch 12 and the connecting rod 2 are engaged, they can prevent the two adjacent shafts from moving relative to each other in the front-back or left-right direction. Then, by locking the lug 3 with the buckle 6, the two adjacent housings 1 can also not be found to move relative to each other in the vertical direction, so that the fixing of the two adjacent housings 1 can be completed quickly.

[0026] Working principle: When using this device, first pass the connecting rod 2 of the upper housing 1 through the U-shaped notch 12 of the lower housing 1 to quickly connect the two shafts together. The U-shaped notch 12 and the connecting rod 2 engage to prevent relative forward / backward or left / right displacement between adjacent shafts. Then, rotate the handle 5 to move the latch 6 upwards. Figure 3 As shown, then turn the handle 5 to move the latch 6 down, and then the latch 6 can lock the hanging ear 3 so that the two adjacent shells 1 cannot detect the relative vertical displacement, so that the fixing work of the two adjacent shells 1 can be completed quickly. The installation of the shaft by using the quick latch 6 fixing splicing method has high work efficiency and can be promoted and used.

[0027] When the handle 5 drives the latch 6 to lock, the limiting piece 8 will eventually be inserted into the limiting groove 9. At this time, the protrusion 10 can prevent the handle 5 from being rotated without human intervention, thus preventing the latch 6 and the hanging ear 3 from becoming loose. This can improve the fixing stability of the device. In summary, although this device is not as stable as welding and screw fixing, the whole splicing process is extremely convenient and easy to use. Moreover, the fixing strength is sufficient for cable laying, so it can be well used in cable wells.
