Description

Technical Field

[0001] This application relates to the field of protective sleeve technology, and in particular to a quick-assembly cable protective sleeve. Background Technology

[0002] Cable protection sleeves are a new type of conduit material widely used in power engineering. With the rapid development of underground power cable laying projects, higher requirements are being placed on cable sleeves. Cable protection sleeves are made of polyethylene (PE) and high-quality steel pipes, undergoing pretreatment processes such as sandblasting and shot blasting, followed by dip coating or painting and heat curing. It is one of the most commonly used electrical insulation conduits for protecting wires and cables. Its wide application is due to its excellent insulation properties, high chemical stability, rust resistance, non-aging properties, and ability to withstand harsh environments.

[0003] For example, Chinese utility model patent CN222839360U discloses a protective sleeve for wires and cables. The insertion post of the left sleeve is inserted into the insertion hole of the right sleeve. When the pulling force applied by the pull rod is released, the limiting slider is reset under the action of the spring. At this time, the limiting head is reset and locked into the limiting hole of the insertion post to limit the movement, thus completing the installation of the protective sleeve. Conversely, by pulling the pull rod, the limiting head is disengaged from the limiting hole of the insertion post, thus completing the disassembly of the protective sleeve. The installation and disassembly of the protective sleeve can be completed with a simple pull and release, which is convenient and quick.

[0004] Regarding the aforementioned technologies, the inventors believe that the cable protection sleeves in these technologies are generally assembled from two half-protection sleeves by bolts, which requires tools to disassemble and assemble the two protection sleeves, thus reducing the convenience of disassembling and assembling the protection sleeves.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] To address the issue that cable protection sleeves in related technologies are generally assembled from two half-protective sleeves using bolts, requiring tools to disassemble and assemble the two protective sleeves, thus reducing the convenience of disassembly and assembly, this application provides a cable protection sleeve that can be quickly spliced.

[0007] The cable protection sleeve provided in this application adopts the following technical solution:

[0008] A quick-connect cable protection sleeve includes two symmetrically arranged half-sleeves, which are fixedly engaged by a locking assembly. The locking assembly includes connecting half-rings fixedly installed at both ends of the half-sleeves. Locking rings are sleeved on the outer sides of the two connecting half-rings at the same end. A locking rod is inserted through the middle of the locking ring. Two sliding grooves are symmetrically opened on the outer side of the locking rings and locking rods. A slider fixedly connected to the locking rod is slidably arranged inside each of the two sliding grooves. A spring is installed between the slider and the side wall of the sliding groove. Locking holes that cooperate with the locking rods are opened on the connecting half-rings.

[0009] Preferably, two guide grooves are symmetrically formed on the connecting half-ring, and guide bars are slidably arranged inside the two guide grooves. The guide bars are fixedly installed on the inner wall of the engaging ring.

[0010] Preferably, the end of the locking rod penetrates the side wall of the locking ring and is fixedly connected to a pull ring.

[0011] Preferably, the length of the locking rod extending out of the locking ring is less than the deformation distance of the spring.

[0012] Preferably, the outer diameter of the connecting half-ring is smaller than the inner diameter of the engaging ring.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. This application, by installing connecting half-rings at both ends of the half-sleeve, and cooperating with the setting of locking rings, locking rods, sliding grooves, sliders, springs, and locking holes, allows the two half-sleeves to be quickly joined together by fitting the locking rings on the outside of the connecting half-rings and engaging the locking rods with the locking holes; conversely, pulling the locking rods separates them from the locking holes, allowing the locking rings to be removed, thus enabling the two half-sleeves to be quickly separated, improving the convenience of half-sleeve assembly and disassembly.

[0015] 2. This application provides a guide groove on the outer side of the connecting half-ring and a guide strip, which is fixedly connected to the locking ring, so that the locking ring can be positioned and installed, thereby facilitating the mating of the locking rod and the locking hole.

[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0021] This application discloses a quick-assembly cable protection sleeve, referring to... Figure 1-3 It includes two symmetrically arranged half-sleeves 1, which are fixedly engaged by a locking assembly 3. The locking assembly 3 includes connecting half-rings 2 fixedly installed at both ends of the half-sleeves 1. A locking ring 31 is sleeved on the outer side of the two connecting half-rings 2 at the same end. A locking rod 33 is provided through the middle of the locking ring 31. Two sliding grooves 34 are symmetrically opened on the outer side of the locking ring 31 and the locking rod 33. A slider 35 fixedly connected to the locking rod 33 is slidably arranged inside the two sliding grooves 34. A spring 36 is installed between the slider 35 and the side wall of the sliding groove 34. A locking hole 22 that cooperates with the locking rod 33 is opened on the connecting half-ring 2.

[0022] Here, by merging the two half-sleeves 1, and then pulling the snap-fit ​​rod 33 to drive the slider 35 to compress the spring 36, the snap-fit ​​rod 33 can retract into the snap-fit ​​ring 31 and the snap-fit ​​ring 31 is placed on the outside of the two connecting half-rings 2. When the snap-fit ​​rod 33 is released, the spring 36 will push the slider 35 to move. The slider 35 drives the snap-fit ​​rod 33 to move and extend into the snap-fit ​​hole 22, thereby fixing the snap-fit ​​ring 31 and completing the mating installation of the two half-sleeves 1.

[0023] Reference Figure 2 and Figure 3 Two guide grooves 21 are symmetrically opened on the connecting half ring 2. Guide bars 32 are slidably arranged inside the two guide grooves 21. The guide bars 32 are fixedly installed on the inner wall of the locking ring 31.

[0024] Here, by providing a guide groove 21 on the connecting half-ring 2 and installing a guide strip 32 on the inner wall of the engaging ring 31, the engaging ring 31 can be positioned and installed.

[0025] Reference Figure 3 The end of the locking rod 33 passes through the side wall of the locking ring 31 and is fixedly connected to the pull ring 37.

[0026] Here, a pull ring 37 is installed at the end of the locking rod 33, which facilitates the movement of the locking rod 33 by pulling it.

[0027] Reference Figure 3The length of the locking rod 33 extending out of the locking ring 31 is less than the deformation distance of the spring 36.

[0028] Here, by making the length of the locking rod 33 extending out of the locking ring 31 less than the deformation distance of the spring 36, the locking rod 33 can be completely retracted into the locking ring 31.

[0029] Reference Figure 1 The outer diameter of the connecting half-ring 2 is smaller than the inner diameter of the locking ring 31.

[0030] Here, by making the outer diameter of the connecting half-ring 2 smaller than the inner diameter of the locking ring 31, the locking ring 31 can be locked on the outside of the connecting half-ring 2.

[0031] The implementation principle of a quick-connect cable protection sleeve according to an embodiment of this application is as follows: In use, the two half-sleeves 1 are closed, and then the guide strip 32 installed on the inner wall of the locking ring 31 cooperates with the guide groove 21 opened on the connecting half-ring 2. Pulling the pull ring 37 drives the locking rod 33, which can drive the slider 35 to squeeze the spring 36 and retract into the inside of the locking ring 31. Then the locking ring 31 is fitted on the outside of the connecting half-ring 2. When the locking ring 31 is in place, the pull ring 37 is released. At this time, the spring 36 can push the slider 35 and the locking rod 33 into the locking hole 22, thereby realizing the installation of the two half-sleeves 1. Conversely, by pulling the pull ring 37, the pull ring 37 drives the locking rod 33 to move. The locking rod 33 drives the slider 35 to squeeze the spring 36 and retract into the inside of the locking ring 31, thereby removing the locking ring 31 from the connecting half-ring 2 and realizing the separation of the two half-sleeves 1.
