DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0025] A spliced ​​fireproof protective sleeve for an environmentally friendly cable comprises a protective sleeve 1, the protective sleeve 1 is composed of a first sleeve 2 and a second sleeve 3, a first connecting ring 4 and a second connecting ring 5 are respectively installed at the ends of the first sleeve 2 and the second sleeve 3 close to each other, a clamping block 6 is installed at one side of the first connecting ring 4 close to the second connecting ring 5, a clamping groove 7 is provided at the bottom of the clamping block 6, and a splicing component 8 is installed inside the second connecting ring 5;

[0026] The splicing assembly 8 is used for quick connection between the first connecting ring 4 and the second connecting ring 5 .

[0027] For further information, see Figure 1 , Figure 2 and Figure 3In this embodiment, the splicing assembly 8 includes a pressing rod 801, an extrusion plate 802, a fitting block 803 and a first spring 804. The pressing rod 801 is installed on the top of the second connecting ring 5, the extrusion plate 802 is installed on the bottom of the pressing rod 801, the fitting block 803 is installed on the extrusion plate 802 at a position corresponding to the card slot 7, and the first spring 804 is installed on the bottom of the extrusion plate 802. When the cable is at high temperature and exposed to the outside at the same time, it will cause the cable temperature to overload and cause damage. By arranging the cable sleeve inside the protective sleeve 1 and fitting the first connecting ring 4 and the second connecting ring 5, the card block 6 is inserted into the second connecting ring 5, thereby pressing the fitting block 803, thereby realizing the contraction of the first spring 804, and realizing the downward movement of the extrusion plate 802, thereby realizing the complete fitting of the card slot 7 and the fitting block 803, thereby realizing the docking of the first connecting ring 4 and the second connecting ring 5, and realizing the connection between the first pipe sleeve 2 and the second pipe sleeve 3.

[0028] Among them, see Figure 1 , Figure 2 and Figure 3 In this embodiment, the pressing rod 801 extends to the interior of the second connecting ring 5, and a receiving groove is provided at a position inside the second connecting ring 5 corresponding to the fitting block 803. A handle 805 is installed on the top of the pressing rod 801, and an anti-slip groove is provided on the outside of the handle 805. When the cable needs to be repaired, the operator presses the pressing rod 801 downward to achieve the downward contraction of the first spring 804, so that the fitting block 803 is separated from the slot 7, and the work of removing the first connecting ring 4 and the second connecting ring 5 is completed.

[0029] Furthermore, please see Figure 2 In this embodiment, a fireproof sleeve 9 is installed inside the first sleeve 2 and the second sleeve 3. The fireproof sleeve 9 is woven from high-purity alkali-free glass fiber, and the outer wall of the fireproof sleeve 9 is coated with organic silica gel. The special material of the fireproof sleeve 9 has the characteristics of high temperature resistance, thermal insulation, flame retardancy, electrical insulation, chemical stability, weather aging resistance, cold resistance, water resistance, oil resistance, ozone resistance, voltage resistance, arc resistance, corona resistance, etc., which can effectively prevent external flames from spreading to the cable.

[0030] For further information, see Figure 1 , Figure 2 and Figure 4In this embodiment, the first extension sleeve 10 and the second extension sleeve 11 are respectively installed on the side close to the first sleeve 2 and the second sleeve 3. The external structure size of the second extension sleeve 11 is smaller than the external structure size of the first extension sleeve 10. The first extension sleeve 10 is provided with a thread groove inside, and the second extension sleeve 11 is provided with an external thread at a position corresponding to the thread groove outside. The first connecting ring 4 and the second connecting ring 5 are coated with a silicone pad 12 on the ends close to each other. When the protective sleeve 1 needs to be installed on the cable, the second extension sleeve 11 is inserted into the inside of the first extension sleeve 10 and the second sleeve 3 is rotated so that the external thread and the thread groove cooperate with each other, so that the second extension sleeve 11 and the first extension sleeve 10 are fully fitted, and the first connecting ring 4 and the second connecting ring 5 are tightly fitted. The friction between the silicone pads 12 greatly improves its sealing performance, effectively blocking external impurities from entering the interior of the cable.

[0031] For further information, see Figure 1 , Figure 2 and Figure 4 In this embodiment, a cross plate 13 is installed inside the fireproof cover 9, and a placement groove 14 is opened inside the cross plate 13. An arc plate 15 is symmetrically installed inside the placement groove 14, and a second spring is installed on the side away from the arc plate 15. By extending the cable into the placement groove 14, the second spring squeezes the arc plate 15 to completely wrap the cable, effectively preventing its position from being shifted. Through the design of the cross plate 13, the pressure resistance of the fireproof cover 9 is effectively improved, and the protective cover 1 is prevented from being squeezed by external force, which causes deformation of the cable.

[0032] In this embodiment, the implementation scenario is specifically as follows: when the cable is at high temperature and is exposed to the outside at the same time, the cable temperature will be overloaded and damaged. By extending the cable to the inside of the placement groove 14, the second spring is used to squeeze the arc plate 15, completely wrap the cable, and effectively prevent its position from shifting. The design of the cross plate 13 effectively improves the compression resistance of the fireproof cover 9, and prevents the protective cover 1 from being squeezed by external force, causing the cable to deform. The special material of the fireproof cover 9 has high temperature resistance, thermal insulation performance, and flame retardant performance, which effectively prevents external flames from spreading to the cable. By inserting the second extension cover 11 into the inside of the first extension cover 10 and rotating the second tube Sleeve 3, so that the external thread and the thread groove cooperate with each other, so that the second extension sleeve 11 and the first extension sleeve 10 are fully fitted, and the first connecting ring 4 and the second connecting ring 5 are tightly fitted, so as to complete the insertion of the clamping block 6 into the second connecting ring 5, thereby pressing the fitting block 803, so that the first spring 804 is contracted, and the extrusion plate 802 moves downward, so that the clamping groove 7 and the fitting block 803 are fully fitted, so that the first connecting ring 4 and the second connecting ring 5 are connected, and the first pipe sleeve 2 and the second pipe sleeve 3 are connected. The friction between the silicone pads 12 is greatly improved, so as to effectively prevent external impurities from entering the interior of the cable.
