DETAILED DESCRIPTION

The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

As shown in Figures 1-3, an insulating protective sleeve for a cable comprises an insulating sleeve 1, an outer sleeve 2 and a fixed sleeve 3. Two insulating sleeves 1 are provided and abut against each other. Most of the existing insulating protective sleeves for cables are segmented and need to be fixedly connected at the joints. The outside of the left insulating sleeve 1 is fixedly connected with the fixed sleeve 3, and the outside of the right insulating sleeve 1 is sleeved with the outer sleeve 2. The fixed sleeve 3 and the outer sleeve 2 are both used to fix the insulating sleeve 1. The right end of the fixed sleeve 3 is provided with a first clamping groove 301, and the right end of the fixed sleeve 3 is fixedly connected with a connecting pipe 4. The surface of the connecting pipe 4 is provided with a plurality of groups of second clamping grooves 401. The outer sliding sleeve of the outer sleeve 2 is provided with a fixed pipe 5, and the upper end of the fixed pipe 5 is sleeved on the outside of the connecting pipe 4. The fixing of the fixed sleeve 3 and the outer sleeve 2 is achieved by clamping the fixing pipe 5 and the connecting pipe 4, thereby achieving the fixation of the two insulating sleeves 1. The interior of the fixed pipe 5 is provided with a first mounting groove 501 and a second mounting groove 502, and the interior of the first mounting groove 501 is fixedly installed with the second mounting groove 503. A spring 7 is provided, and the other end of the first spring 7 is fixedly connected with a clamping block 8, and the lower end of the clamping block 8 is inserted into the second clamping groove 401. A second spring 9 is fixedly installed in the second installation groove 502, and the other end of the second spring 9 is fixedly connected with a push block 10, and the left side of the push block 10 abuts against the right end of the connecting pipe 4. When fixing the insulating protective sleeve, the fixing pipe 5 is sleeved on the connecting pipe 4, and the clamping block 8 is inserted into the second clamping groove 401 through the first spring 7. At this time, the second spring 9 is in a compressed state. The push block 10 is pushed toward the connecting tube 4, and the fixing tube 5 is fixedly sleeved on the outside of the connecting tube 4 in cooperation with the clamping block 8. A push-pull ring 11 is provided on the right side of the fixing tube 5, and an extrusion rod 1101 is fixedly connected to the left end of the push-pull ring 11. The left end of the extrusion rod 1101 passes through the side plate of the fixing tube 5 and extends into the interior of the first mounting groove 501. When disassembly is required, the push-pull ring 11 is pushed to make the extrusion rod 1101 squeeze the inclined surface of the clamping block 8 to make it disengage from the second clamping groove 401, and the disassembly is completed.

Specifically, in this embodiment, the outer sleeve 2 includes an upper sleeve 201 and a lower sleeve 202. Slots are provided at both ends of the upper sleeve 201, and plug plates are fixedly connected at both ends of the lower sleeve 202. The slots and the plug plates cooperate to make the outer sleeve 2 sleeved on the surface of the insulating sleeve 1. The installation and disassembly are simple, which is convenient for subsequent maintenance and repair.

Specifically, in this embodiment, the left ends of the upper sleeve 201 and the lower sleeve 202 are fixedly connected with a connecting block 6, and the connecting block 6 matches the first slot 301. Positioning can be performed through the connecting block 6 and the first slot 301 to facilitate subsequent installation and avoid misalignment between the fixed sleeve 3 and the outer sleeve 2 after fixation.

Specifically, in this embodiment, protrusions are provided on the left ends of the upper sleeve 201 and the lower sleeve 202 , and a matching groove is provided on the lower end of the fixing tube 5 , so that the fixing tube 5 can fix the outer sleeve 2 .

Specifically, in this embodiment, the left end of the extrusion rod 1101 is a sphere, and the diameter of the sphere is larger than the diameter of the right extrusion rod 1101, so that the extrusion rod 1101 can remain in the fixed tube 5, making it convenient to squeeze the inclined surface of the block 8 through the extrusion rod 1101 to complete the disassembly.

Specifically, in this embodiment, the right end of the block 8 is provided with an inclined surface.

The working principle of the utility model is: firstly, the upper sleeve 201 and the lower sleeve 202 are sleeved on the surface of the insulating sleeve 1 through the slots and the plug-in plate to assemble into the outer sleeve 2, and the outer sleeve 2 and the fixed sleeve 3 are connected together through the connecting block 6 and the first slot 301, and then the fixed tube 5 is slidably sleeved on the outer sleeve 2.

When the insulating protective sleeve is fixed, the upper end of the fixing tube 5 is sleeved on the connecting tube 4, and the clamping block 8 is inserted into the second clamping groove 401 through the first spring 7. At this time, the second spring 9 is in a compressed state, so that the push block 10 pushes toward the connecting tube 4, and cooperates with the clamping block 8 to make the fixing tube 5 fixedly sleeved on the outside of the connecting tube 4;

When disassembly is required, the push-pull ring 11 is pushed to make the extrusion rod 1101 squeeze the inclined surface of the block 8 to make it disengage from the second slot 401, and the disassembly is completed. The installation and disassembly operation of this device is simple and convenient, and it does not need to be fixed by bolts, so it is very practical.

The above shows and describes the basic principle, main features and advantages of the utility model.
