Description

Technical Field

[0001] This utility model relates to the fields of industrial safety and electrical engineering technology, and in particular to a loose-resistant fireproof and heat-insulating protective sleeve. Background Technology

[0002] Fireproof and heat-insulating sheaths are protective devices used to protect various objects from high temperatures and flames, preventing the spread of fire and reducing heat transfer. Cable protection is of paramount importance, and cable protective heat-insulating sheaths are a typical application of fireproof and heat-insulating sheaths.

[0003] The protective and heat-insulating sheath of a cable is usually composed of multiple layers of materials (such as insulation layers, heat insulation layers, etc.), each with its specific function, to ensure the reliability and safety of the cable in various environments. The working principle is to isolate fire sources and high-temperature environments through the synergistic effect of the multi-layer structure, suppress heat transfer, and prevent fire from spreading into the cable, ensuring the safe operation of the cable in extreme environments such as high temperature and fire, and avoiding electrical fires or equipment damage.

[0004] In the application of traditional cable protective and heat-insulating sheaths, although the main function of the sheath is to protect the cable from the effects of external environments such as high temperature, fire, and physical damage, during actual cable installation, multiple external factors (such as vibration, temperature changes, and mechanical impact) often cause loosening between the sheath and the cable. Traditional sheath fixing structures are simple and use a simple sleeve method, without considering the influence of external factors on the relative position of the sheath and the cable in a dynamic environment. This can easily cause the sheath to detach or shift from the cable. This loosening phenomenon is particularly prominent in high temperature, frequent vibration, or high pressure environments. In particular, the thermal expansion and contraction of the cable during operation will exacerbate the loosening problem of the sheath, thereby affecting its heat insulation, fireproof, and protective functions. Therefore, an anti-loosening fireproof and heat-insulating sheath is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a non-loosening fireproof and heat-insulating sheath, which aims to improve the problem of the single fixing method of cables and sheaths in the existing technology and the easy loosening of the sheath.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fireproof and heat-insulating sheath with anti-loosening properties includes a sheath body, inside which a cable body is installed. Specifically, there is a pair of sheath bodies, and a splicing assembly is provided between the pair of sheath bodies. A clamping ring 1 is installed on the top side of the cable body, and a clamping ring 2 is installed on the side of the cable body away from the clamping ring 1. Mounting blocks are symmetrically fixedly connected to the sides of the clamping ring 1 and the clamping ring 2 away from the sheath body. A bolt is installed in the middle of the mounting block, and a nut is provided on the side of the mounting block away from the bolt.

[0008] As a further description of the above technical solution:

[0009] The splicing assembly includes a socket, which is fixedly connected to one end of the sheath body. A mounting base is fixedly connected to the end of the sheath body away from the sheath body. The inner wall of the socket is uniformly provided with protrusions.

[0010] As a further description of the above technical solution:

[0011] The first clamping ring and the second clamping ring are connected by the bolt and the nut.

[0012] As a further description of the above technical solution:

[0013] The mounting block is installed on the side of the sheath body away from the cable body.

[0014] As a further description of the above technical solution:

[0015] The mounting block has a threaded hole in the middle, and the bolt is threaded into the middle of the threaded hole.

[0016] As a further description of the above technical solution:

[0017] The outer sides of the first clamping ring and the second clamping ring are fixedly connected with reinforcing ribs, which are sleeved on the outer sides of the sheath body and the cable body.

[0018] As a further description of the above technical solution:

[0019] The mounting base has evenly spaced grooves in the middle, and the protrusion is slidably connected to the middle of the grooves.

[0020] As a further description of the above technical solution:

[0021] The cable body is installed on the inner wall of the socket and the inner wall of the mounting base.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, clamping ring one and clamping ring two are installed at the splice of the socket and the mounting base, and the bolts on the mounting block are tightened with the nuts through the threaded holes to achieve tight clamping of the cable body. The outer reinforcing ribs further enhance the stability of clamping ring one and clamping ring two, which helps to reduce the loosening between the sheath body and the cable body, thereby reducing the risk of electrical faults or fires caused by sheath loosening.

[0024] 2. In this utility model, by sliding the protrusion on the socket in the splicing component and the sliding groove on the mounting base, a pair of sheath bodies can be spliced ​​together quickly and accurately during installation to wrap the cable body. This is not only convenient to operate, but also greatly enhances the efficiency of the extended installation of the sheath body and the effective fixation and protection of the cable body compared with the traditional simple sleeve installation.

[0031] 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.

[0032] Reference Figure 1 and Figure 2This utility model provides an embodiment of a fireproof and heat-insulating sheath that is designed to prevent loosening. It includes a sheath body 1, with a cable body 2 installed inside. Specifically, there is a pair of sheath bodies 1, with a splicing assembly 10 between them. A clamping ring 3 is installed on the top side of the cable body 2, and a clamping ring 4 is installed on the side of the cable body 2 away from the clamping ring 3. Mounting blocks 5 are symmetrically fixedly connected to the sides of the clamping rings 3 and 4 away from the sheath body 1. A bolt 6 is installed in the middle of the mounting block 5, and a nut 7 is provided on the side of the mounting block 5 away from the bolt 6. The clamping rings 3 and 4 are connected by the bolt 6 and the nut 7. The mounting block 5 is installed on the side of the sheath body 1 away from the cable body 2. A threaded hole 8 is opened in the middle of the mounting block 5, and the bolt 6 is threaded into the middle of the threaded hole 8. Reinforcing ribs 9 are fixedly connected to the outer sides of the clamping rings 3 and 4, and the reinforcing ribs 9 are sleeved on the outer sides of the sheath body 1 and the cable body 2.

[0033] Specifically, by installing clamp ring 3 at the joint between socket 11 and mounting base 12, and clamp ring 4 correspondingly installed on the other side of cable body 2 away from clamp ring 3, bolt 6 is passed through the pre-drilled threaded hole 8 on mounting block 5 and tightened with nut 7, clamp ring 3 and clamp ring 4 can tightly hug cable body 2, forming a stable clamping force. The outer reinforcing rib 9 is firmly connected to clamp ring 3 and clamp ring 4, further enhancing the stability of the clamp ring structure. During long-term operation of the cable, even when faced with complex external factors such as severe vibration and significant temperature changes, the fastening system composed of clamp ring 3, clamp ring 4, mounting block 5, bolt 6, nut 7, and reinforcing rib 9 can continuously maintain effective restraint on cable body 2, ensuring that sheath body 1 and cable body 2 are always tightly fitted, effectively reducing relative displacement and loosening between the two, and helping to reduce the risk of cable insulation damage, electrical faults, or fires caused by loosening of sheath body 1.

[0034] Reference Figure 3 and Figure 4 The splicing assembly 10 includes a socket 11, which is fixedly connected to one end of the sheath body 1. The end of the sheath body 1 away from the sheath body 1 is fixedly connected to a mounting base 12. The inner wall of the socket 11 is evenly provided with protrusions 13. The mounting base 12 is evenly provided with a sliding groove 14 in the middle. The protrusions 13 are slidably connected to the middle of the sliding groove 14. The cable body 2 is installed on the inner wall of the socket 11 and the inner wall of the mounting base 12.

[0035] Specifically, by placing the cable body 2 inside the reserved space of the two sheath bodies 1, and using the evenly distributed protrusions 13 on the inner wall of the socket 11 in the splicing assembly 10 and the corresponding sliding grooves 14 in the middle of the mounting base 12, the two sheath bodies 1 can be spliced ​​quickly and accurately. During the splicing process, the protrusions 13 slide smoothly into the sliding grooves 14, automatically calibrating the position of the sheath bodies 1, and achieving preliminary positioning of the relative positions of the sheath bodies 1 and the cable body 2, which helps to improve installation efficiency. The structure of the protrusions 13 and the sliding grooves 14 tightly fitting together enhances the stability of the splice and helps the fireproof and heat-insulating sheath maintain its complete covering structure during long-term use.

[0036] Working principle: First, by placing the cable body 2 inside the two sheath bodies 1, the sheath bodies 1 are spliced ​​by the sliding engagement of the protrusion 13 on the socket 11 in the splicing assembly 10 and the slide groove 14 on the mounting base 12, and the sheath bodies 1 are initially positioned. Then, clamping ring 1 3 and clamping ring 2 4 are installed at the splicing point of the socket 11 and the mounting base 12. The bolt 6 on the mounting block 5 is passed through the threaded hole 8 and the nut 7 is tightened, so that clamping ring 1 3 and clamping ring 2 4 clamp the cable body 2. At the same time, the reinforcing rib 9 further enhances the stability of the clamping ring, effectively preventing loosening between the sheath body 1 and the cable body 2. During the operation of the cable, even if it is affected by external factors such as vibration and temperature changes, the fastening structure of the splicing assembly 10 and clamping ring 1 3 and clamping ring 2 4 can maintain the relative position of the sheath body 1 and the cable body 2.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
