Description

Technical Field

[0001] The utility model relates to the technical field of cable protection, in particular to a fireproof blanket for cable joints that is convenient to connect. Background Technique

[0002] A fire extinguishing blanket, also known as a fireproof blanket, a fireproof quilt, a fireproof blanket, a fireproof blanket, a flame retardant blanket, or an escape blanket, is a fabric woven from materials such as fiberglass through special treatment. It can play a role in isolating heat sources and flames and can be used to extinguish oil pan fires or be draped over the body for escape.

[0003] Existing fireproof blankets used to protect cable joints have certain drawbacks during installation and use. Their sealing performance is not good. Especially after long-term operation, the possibility of cable spontaneous combustion causing an explosion and injuring other cables in the cable trench is very high. Their safety performance is still not ideal, and their protection performance is low, bringing certain adverse effects to the using process.

[0004] After retrieval of existing Chinese patents: A fireproof blanket for protecting cable joints (publication number: CN213661179U), including a fireproof blanket main body. An efficient heat-resistant and high-temperature-resistant mechanism is arranged on the outer surface of one side of the fireproof blanket main body. The efficient heat-resistant and high-temperature-resistant mechanism includes an insulating layer, a fireproof coating, heat-insulating cotton, and a protective layer. A support rod penetrates through the inside of the fireproof blanket main body. A protective mechanism is arranged at the upper end of the fireproof blanket main body. The protective mechanism includes a wear-resistant frame, a metal reinforcement layer, a fireproof sealing material, and a shock-resistant layer. A cable joint protection mechanism is arranged on one side of the protective mechanism. The cable joint protection mechanism includes a fireproof bag, a sealing groove, a waterproof sealing gasket, and a socket joint. The fireproof blanket for protecting cable joints described in this utility model has the advantages of high efficiency in heat resistance and high temperature resistance, a cable joint protection mechanism, and good protection performance, increasing the service life and improving the use safety factor, bringing a better use prospect.

[0005] Although the above patent achieves the purpose of fire and heat resistance and protection by setting an efficient heat-resistant and high-temperature-resistant mechanism, the drawback is that after the fireproof blanket main bodies are connected together, the cable wires and connectors are not fully wrapped, so that a part of the cable wires and connectors is exposed to the external environment, which is likely to cause damage to the cable wires and connectors.

[0006] Therefore, it is necessary to invent a fireproof blanket for cable joints that is convenient to connect to solve the above problems. Content of the Utility Model

[0007] The purpose of the utility model is to provide a fireproof blanket for cable joints that is convenient to connect to solve the problems raised in the above background technique.

[0008] To achieve the above object, the present utility model provides the following technical solution: A fireproof blanket for a cable joint that is convenient to connect, including a fireproof blanket body. A limiting slot is opened inside the fireproof blanket body. A U-shaped fixing frame is installed on the side of the fireproof blanket body. A sliding insertion rod is connected inside the U-shaped fixing frame. There are multiple groups of the sliding insertion rods, and multiple groups of the sliding insertion rods are linearly distributed inside the U-shaped fixing frame. One end of the sliding insertion rod is fixed with a connecting plate, and a pulling handle is fixed on the side of the connecting plate. A guiding plate is fixed on the outer wall of the sliding insertion rod, and a return spring is fixedly connected to the side of the guiding plate. A fixing insertion block is installed at one end of the fireproof blanket body away from the limiting slot. A second limiting hole is opened inside the fixing insertion block. The inner diameter dimension of the second limiting hole is the same as the outer diameter dimension of the sliding insertion rod, and the second limiting hole is slidably connected with the sliding insertion rod.

[0009] Preferably, a first limiting hole is opened inside the limiting slot.

[0010] Preferably, a T-shaped guiding slider is fixed on one side of the guiding plate, and a limiting sliding slot is opened on the side of the U-shaped fixing frame.

[0011] Preferably, a first arc-shaped clamping block is fixed on the inner side of the fireproof blanket body, and a second arc-shaped clamping block is arranged below the first arc-shaped clamping block.

[0012] Preferably, a cable is arranged inside the second arc-shaped clamping block, and a connector is installed at one end of the cable.

[0013] Preferably, an insulating layer is arranged inside the fireproof blanket body, and a fireproof coating is connected to the inner side of the insulating layer.

[0014] Preferably, a heat insulating cotton is connected to the inner side of the fireproof coating, and a protective layer is connected to the inner side of the heat insulating cotton.

[0015] The technical effects and advantages of the present utility model:

[0016] 1. By setting up an installation component, a U-shaped fixing frame, sliding insertion rods, a connecting plate, a pulling handle, a guiding plate, a return spring, a fixed insertion block, a second limiting hole, and a cable, pulling the pulling handle causes the pulling handle to drive the connecting plate to move outward from the U-shaped fixing frame. Multiple groups of sliding insertion rods are fixed to the side of the connecting plate, so that multiple groups of sliding insertion rods move outward from the U-shaped fixing frame, thereby disengaging the limitation on the second limiting hole opened inside the fixed insertion block. In this way, the fixed insertion block can be taken out from the limiting slot, and thus the fireproof blanket body can be disassembled from the connection between the two cables; when it is necessary to fully wrap the fireproof blanket body around the connector between the two cables, pull the pulling handle, so that the pulling handle drives the connecting plate to move outward from the U-shaped fixing frame, and the connecting plate drives multiple groups of sliding insertion rods to move outward. A guiding plate is fixedly arranged on the outer walls of multiple groups of sliding insertion rods together, and a return spring is fixed to the side of the guiding plate. When the guiding plate moves outward, the return spring deforms and stretches. Then, insert the fixed insertion block fixed to one end of the fireproof blanket body into the limiting slot, and determine the insertion depth according to the thickness of the cable. Then release the pulling handle. Under the action of the deformation and reset of the return spring, multiple groups of sliding insertion rods move back and insert into the second limiting holes correspondingly opened in the fixed insertion block. In this way, the fireproof blanket body wraps around the connector between the two cables, thus preventing the situation that some positions of the cables and the connector are exposed in the external environment and are easily damaged, further improving the usage range of the device, and at the same time facilitating the disassembly and assembly work of the fireproof blanket body;

[0017] 2. By fixing a first arc-shaped clamping block and a second arc-shaped clamping block on the inner side of the fireproof blanket body, the first arc-shaped clamping block and the second arc-shaped clamping block can clamp and fix the two cables, thus preventing the fireproof blanket body from sliding on the two cables;

[0018] 3. By arranging an insulating layer, a fireproof coating, heat-insulating cotton, and a protective layer inside the fireproof blanket body, the fireproof blanket body plays the roles of insulation, fire prevention, heat insulation, and protection. BRIEF DESCRIPTION OF THE DRAWINGS
