Based on the matching of the first semicircular shroud ring 1 and the second semicircular shroud ring 2, the device is well contacted with the circular tube-shaped bus, is firmly fixed, and is convenient for hanging the grounding wire; the device has simple structure and small volume, and meets the standard requirement that the grounding installation positions are independently arranged and staggered; due to the cooperation of the first magnet 6 and the second magnet 7, the operator can easily mount the device on the tubular busbar.
Specifically, the lower end of the first semicircular hoop 1 and the lower end of the second semicircular hoop 2 are respectively provided with a first fixing block 11 and a second fixing block 21; the first fixing block 11 and the second fixing block 21 are respectively provided with a second magnet 12 and a fourth magnet 22; based on the second magnet 12 and the fourth magnet 22, the lower end of the first semicircular band 1 is fixedly connected with the lower end of the second semicircular band 2. Through the cooperation of second magnet 12 and fourth magnet 22, can be because of magnetic force mutual attraction and close contact when first fixed block 11 and second fixed block 21 are close to promptly, strengthen the first semicircle shroud ring 1 of magnetism and the stability of being connected between the second semicircle shroud ring 2, to the installation or demolish and consider, great improvement the convenience of device.

Furthermore, the magnet is fixed, so that the magnet is easier to disassemble and assemble, and the magnet is a relatively complete assembly structure. When using magnets, on the one hand no material is wasted and on the other hand there is substantially no possibility of damage and maintenance.
Specifically, the sizes of the first protrusion 13 and the second protrusion 23 are respectively adapted to the inner diameters of the first semicircular hoop 1 and the second semicircular hoop 2.
Specifically, the first fixing block 11 and the second fixing block 21 are respectively provided with a first through hole and a second through hole correspondingly; the first fixing block 11 and the second fixing block 21 are fixed by passing through the first through hole and the second through hole based on bolts. The first semi-circular hoop 1 and the second semi-circular hoop 2 are fixed by bolts
Specifically, the first bump 13 and the second bump 23 are made of rubber.
Further, rubber is a high-elasticity polymer material with reversible deformation, is rich in elasticity at room temperature, can generate large deformation under the action of small external force, and can recover the original shape after the external force is removed. The rubber belongs to a completely amorphous polymer, and has low glass transition temperature and large molecular weight which is more than hundreds of thousands. Linear structure: the general structure of unvulcanized rubber. Because of the large molecular weight, the macromolecular chains are in the shape of random-winding-curve clusters without the action of external force. When the external force is removed, the entanglement degree of the coil is changed, the molecular chain rebounds, and a strong recovery tendency is generated, which is the source of high elasticity of rubber. Branched chain structure: the aggregation of the branches of the macromolecular chains of the rubber forms a gel. Gels are detrimental to both rubber properties and processing. When rubber mixing is carried out, various compounding agents cannot enter a gel area, a local blank is formed, reinforcement and crosslinking cannot be formed, and weak parts of products are formed. A cross-linked structure: linear molecules are connected to each other by bridges of atoms or groups of atoms to form a three-dimensional network. This structure is continuously strengthened as the curing history progresses. Thus, the free-flowing ability of the segment is decreased, plasticity and elongation are decreased, strength, elasticity and hardness are increased, and compression set and swelling degree are decreased.
Further, the selected rubber is natural rubber, is prepared from rubber tree collected latex and is a polymer of isoprene. Has good wear resistance, high elasticity, high breaking strength and high elongation. Natural rubber typically contains 92% to 95% rubber hydrocarbons, while non-rubber hydrocarbons comprise 5% to 8%. Because of different preparation methods, different production places and even different glue-collecting seasons, the proportions of the components may be different but are basically within the range. It is easy to age in air, become sticky when heated, and is easy to expand and dissolve in mineral oil or gasoline, and is alkali-resistant but not strong acid-resistant. The advantages are that: good elasticity and acid and alkali resistance. The disadvantages are as follows: it is heat-resistant, oil-resistant (can resist vegetable oil), is a raw material for making adhesive tape, rubber tube and rubber shoes, and is suitable for making damping parts and products used in liquid with hydroxyl, such as automobile brake oil, ethanol, etc.
Specifically, the hinge 3 is a stainless steel hinge 3.
According to the invention, based on the matching of the first semi-circular shroud ring and the second semi-circular shroud ring, the device is well contacted with the circular tube-shaped bus, the fixation is firm, and the grounding wire can be conveniently hung; the device has simple structure and small volume, and meets the standard requirement that the grounding installation positions are independently arranged and staggered; based on the cooperation of the first magnet and the second magnet, an operator can simply install the device to the round tubular bus.
