Description

Technical Field

[0001] This utility model relates to the field of cable protection technology, specifically a protective device for security and low-voltage electrical engineering. Background Technology

[0002] Security and low-voltage electrical engineering is a crucial part of modern building intelligence. It utilizes low-voltage and low-current technologies (usually referring to systems below the safety voltage level, such as AC below 36V or DC below 24V) to achieve security functions. It mainly includes: video surveillance systems, intrusion alarm systems, access control systems, electronic patrol systems, parking management systems, building intercom systems, etc.

[0003] In security and low-voltage electrical engineering, cables are needed to transmit electrical energy and signals. Therefore, cable protection is crucial. When cables pass through housing structures, such as equipment boxes and cabinets, a protective sleeve needs to be fitted over the outside of the cable to separate it from the edge of the housing structure in order to prevent the cable from being squeezed or cut by the edge of the housing structure. However, the commonly used protective sleeves are one-piece ring structures that need to be fitted from the end of the cable. If the cable has already been installed or the protective sleeve is damaged and needs to be reinstalled, the cable end connection needs to be removed for installation. This operation is inconvenient and needs further optimization. Based on this, a protective device for security and low-voltage electrical engineering is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a protective device for security and low-voltage electrical engineering in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective device for security and low-voltage electrical engineering, comprising a wire protection assembly, wherein the wire protection assembly comprises a semi-polygonal block, a semi-cylindrical column, a T-shaped slot, and a T-shaped plug;

[0006] The semi-cylindrical column is fixed to the bottom of the semi-polygonal block. Two sets of semi-polygonal blocks and semi-cylindrical columns are symmetrically arranged. The T-shaped slot is opened at the top of one semi-polygonal block and passes through one side of this semi-polygonal block. The T-shaped insert is fixed to the side of the other semi-polygonal block.

[0007] The two semi-polygonal blocks are joined together by vertically inserting a T-shaped plug into a T-shaped slot;

[0008] Two sets of semi-polygonal blocks and semi-cylindrical cylinders are connected to each other and sleeved on the outside of the cable, and the semi-cylindrical cylinders pass through the through hole of the shell structure to achieve the separation operation between the cable and the edge of the shell structure.

[0009] The outer walls of the two semi-cylindrical columns are formed with threaded grooves, and the semi-cylindrical columns are threadedly connected to U-shaped nuts through the threaded grooves. The U-shaped nuts fit against the outer wall of the shell structure to realize the installation and fixation of the wire protection assembly and the shell structure.

[0010] As a further improvement of this utility model, the opening size of the U-shaped nut is larger than the outer diameter of the cable, so as to realize the connection operation between the U-shaped nut and the cable at any position.

[0011] As a further embodiment of this utility model: a semi-circular groove is formed on the inner side of the semi-cylindrical column, and two symmetrically distributed semi-circular ring sealing blocks are installed on the two semi-cylindrical columns through the semi-circular groove. The semi-circular ring sealing blocks are attached to the outer wall of the cable to seal the gap between the cable and the cable protection assembly.

[0012] As a further improvement of this utility model: the inner diameter of the semi-circular sealing block is set according to the outer diameter of the cable, and the outer diameter and height of the semi-circular sealing block match the inner wall diameter and height of the semi-circular groove one by one.

[0013] As a further embodiment of this utility model: one set of the semi-polygonal blocks, semi-cylindrical columns, T-shaped slots, and semi-circular grooves are integrally formed by injection molding, and another set of the semi-polygonal blocks, semi-cylindrical columns, T-shaped inserts, and semi-circular grooves are integrally formed by injection molding.

[0014] The U-shaped nut is integrally formed by injection molding.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By setting up a modular cable protection assembly and U-shaped nut, it is possible to quickly assemble and fix the cable. During this process, there is no need to consider whether the cable has passed through the holes in the housing structure or whether the end of the cable has been fixed. Even if the cable has passed through the holes in the housing structure and the end is fixed, it can still be installed and disassembled smoothly, making it more flexible and convenient to use.

[0022] 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.

[0023] Please see Figures 1-4 In this embodiment of the utility model, a protective device for security and low-voltage engineering includes a wire protection assembly 1, which includes a semi-polygonal block 101, a semi-cylindrical column 102, a T-shaped slot 103, and a T-shaped plug 104.

[0024] The semi-cylindrical column 102 is fixed to the bottom of the semi-polygonal block 101. Two sets of semi-polygonal blocks 101 and semi-cylindrical columns 102 are symmetrically arranged. The T-shaped slot 103 is opened on the top of one semi-polygonal block 101 and passes through one side of the semi-polygonal block 101. The T-shaped insert 104 is fixed to the side of the other semi-polygonal block 101.

[0025] Two semi-polygonal blocks 101 are joined together by vertically inserting a T-shaped plug 104 into a T-shaped slot 103;

[0026] Two sets of semi-polygonal blocks 101 and semi-cylindrical cylinders 102 are connected to each other and sleeved on the outside of the cable 4, and the semi-cylindrical cylinders 102 pass through the through hole of the shell structure to realize the separation operation between the cable 4 and the edge of the shell structure.

[0027] The outer walls of the two semi-cylindrical columns 102 are formed with threaded grooves. The semi-cylindrical columns 102 are threadedly connected to U-shaped nuts 3 through the threaded grooves. The U-shaped nuts 3 fit against the outer wall of the shell structure to realize the installation and fixation of the wire protection assembly 1 to the shell structure.

[0028] The opening size of the U-nut 3 is larger than the outer diameter of the cable 4, which is used to enable the U-nut 3 to be connected to the cable 4 at any position.

[0029] The inner side of the semi-cylindrical column 102 is formed with a semi-circular groove 105. Two semi-cylindrical columns 102 are fitted with two symmetrically distributed semi-circular ring sealing blocks 2 through the semi-circular groove 105. The semi-circular ring sealing blocks 2 are attached to the outer wall of the cable 4 to seal the gap between the cable 4 and the cable protection assembly 1.

[0030] In this embodiment: When using this device, it is not necessary to consider whether the cable 4 has passed through the hole in the housing structure or whether the end of the cable 4 has been fixedly installed. If the cable 4 has passed through the hole in the housing structure and the end is fixed, it can be installed smoothly. The operation method is as follows:

[0031] First, install two semi-circular sealing blocks 2 into the inner side of the semi-circular grooves 105 on the two sets of semi-polygonal blocks 101 and semi-cylindrical columns 102 respectively. Then, bring the two sets of semi-polygonal blocks 101 and semi-cylindrical columns 102 closer to each other from both sides of the cable 4 and make them staggered vertically, so that the T-shaped plug 104 is inserted into the T-shaped slot 103, thereby realizing the assembly of the cable protection assembly 1. At the same time, the semi-circular sealing blocks 2 are attached to the outside of the cable 4.

[0032] Next, slide the cable protection assembly 1 and the semi-circular sealing block 2 down along the cable 4, so that the semi-circular column 102 is inserted into and passes through the hole in the shell structure.

[0033] Next, the U-shaped nut 3 is fitted onto the outside of the cable 4 through the notch (it should be noted that the U-shaped nut 3 is located at the bottom of the housing structure). Then, the U-shaped nut 3 is moved up and threaded into the semi-cylindrical column 102 and tightened. Finally, the U-shaped nut 3 fits tightly against the bottom of the housing structure, thus completing the installation of the device.

[0034] The cable protection component 1 can separate the cable 4 from the edge of the housing structure, effectively preventing the edge of the housing structure from squeezing or cutting the cable 4.

[0035] Please refer to this carefully. Figures 1-4 The inner diameter of the semi-circular sealing block 2 is set according to the outer diameter of the cable 4. The outer diameter and height of the semi-circular sealing block 2 match the inner diameter and height of the semi-circular groove 105.

[0036] In this embodiment, the gap between the cable 4 and the cable protection component 1 can be sealed by the semi-circular sealing block 2, which has a certain dustproof effect. By setting different models of semi-circular sealing blocks 2, it can adapt to cables 4 of different diameters, effectively improving the versatility of the device.

[0037] Please refer to this carefully. Figures 1-4 One set of semi-polygonal blocks 101, semi-cylindrical columns 102, T-shaped slots 103, and semi-circular grooves 105 are integrally formed by injection molding, and another set of semi-polygonal blocks 101, semi-cylindrical columns 102, T-shaped inserts 104, and semi-circular grooves 105 are integrally formed by injection molding.

[0038] The U-shaped nut 3 is integrally molded using an injection molding process.

[0039] In this embodiment, it should be noted that the semi-circular sealing block 2 is also integrally molded by rubber injection molding. The wire protection component 1, U-shaped nut 3 / semi-circular sealing block 2 are each produced and molded independently, and then assembled for use, which facilitates standardized production and promotion.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
