Detailed ways

The structures involved in the present invention or the technical terms used will be further described below. These descriptions are only used to illustrate how the present invention is implemented by way of examples, and do not constitute any limitation on the present invention.

The existing chain-type quick hoop includes a locking mechanism and multiple hoop units. The multiple hoop units are connected end to end, installed on the installation tower, and then the hoop is locked through the locking mechanism. By adding or subtracting hoop units, the installation needs of different types and sizes of installation towers can be met. Chain-type quick hoops generally have a structure used to connect support arms. The support arms are used to fix the holding poles, and the holding poles are used to install antenna equipment.

The traditional hoop unit has a mounting hole for connecting the arm on its outer wall. In fact, with this arrangement, the weight of the antenna device is concentrated at the connection between the hoop unit and the mounting hole. If the welding between the mounting hole and the hoop unit is not firm, the antenna will Under the weight of the equipment, it is easy to cause the load-bearing instability of the hoop unit, causing the mounting holes to easily fall off.

As shown in Figures 1-5, the present invention adopts a chain-type quick hoop. The hoop includes a plurality of arc-shaped hoop units 1 connected end to end. The hoop unit 1 is a solid body, and the hoop unit 1 is provided with mounting holes 12 and A pair of connecting holes 11 are symmetrically arranged at the beginning and end of the hoop unit. The mounting hole 12 is between the two connecting holes 11. All the mounting holes 12 and the connecting holes 11 on the hoop are located on the same circle. The hole used to connect the hoop units is used as the connection hole 11, and the hole used to mount the load is the mounting hole 12, and the load is the antenna device. All mounting holes 12 and connecting holes 11 on the hoop are located on the central circumferential line of the hoop unit 1 .

In the present invention, the connecting hole 11 is arranged inside the hoop unit 1 to effectively prevent the connecting hole 11 from falling. Moreover, the weight of the antenna equipment is distributed over the entire hoop unit 1, which greatly increases the load-bearing capacity and safety protection function of the hoop unit 1. The mounting hole 12 and the connecting hole 11 are arranged on the same circle, and the stress on the bolts in the connecting hole 11 and the bolt in the mounting hole 12 are transferred to the hoop unit 1, and the stiffness of the hoop unit 1 is used to disperse the stress. It greatly increases the load-bearing effect and safety, and improves the mounting capacity and service life of the hoop.

In this embodiment, the hoop unit 1 adopts a solid body structure, and the mounting hole 12 and the connecting hole 11 are solidly connected. The hoop unit 1 has greater strength, and the antenna device can be installed safely and reliably without being affected by external forces.

In this embodiment, the mounting hole 12 and the connection hole 11 of the hoop unit 1 are both formed in the form of openings. The hoop unit 1 is integrally formed without welding points and has high strength and stable corrosion resistance.

As a specific embodiment, at least one pair of mounting holes 12 is provided inside the hoop unit 1, and the mounting holes 12 are symmetrically arranged. In this embodiment, a pair of mounting holes 12 are provided inside the hoop unit 1. The connection holes 11 are symmetrically arranged, which helps the stability of the connection between the hoop units 1, and the mounting holes 12 are symmetrically arranged, which further helps the stability of the antenna device during installation.

As a specific embodiment, a weight-reducing hole 13 is opened in the center of the hoop unit 1 , and the weight-reducing hole 13 is located on the circle where the mounting hole 12 and the connecting hole 11 are located. The traditional hoop unit 1 adopts an almost hollow structure inside, and its main purpose is to reduce its own weight. However, while reducing its own weight, the strength of the hoop unit 1 itself is ignored. The hoop unit 1 needs to bear the weight of the antenna device, and the weight of the antenna device depends on the situation. If the weight of the antenna device is much greater than the strength that the hoop unit 1 itself can bear, the hoop unit 1 is easily damaged, causing the antenna device to fall easily. , not only causes damage to materials and equipment, causing a waste of resources, but also easily causes safety hazards. Some hoop units 1 adopt an internal hollow structure, and then set reinforcing bars inside the hoop unit 1 to enhance the load-bearing capacity of the hoop unit 1. However, due to too many hollow structures, the strength of the hoop unit 1 itself is reduced. If the hoop unit 1 is designed as a whole, it will inevitably greatly increase the weight of the hoop unit itself. The consequent consequence is that the hoop needs to be carried when mounting the tower. Due to the heavy weight, it is extremely inconvenient to carry. If most of the inside of the hoop unit 1 is With the hollow design, it is obvious that although the weight of the hoop unit 1 itself is reduced, its own strength will also be greatly reduced. Therefore, the hoop unit of the present invention has weight-reducing holes inside, and the hoop unit 1 is a partially hollow structure, which not only meets the dual requirements of reducing its own weight and ensuring its own strength, but also increases the toughness and plasticity of the hoop unit 1. The hoop unit 1 is connected The stress is evenly distributed when the arm is supported. At the same time, the weight reduction hole 13 is arranged at the center of the hoop unit 1 to ensure the stability of the hoop unit 1 when it is stressed.

As a specific embodiment, the hoop unit 1 has an inner end surface 14 and an outer end surface 15. Both the inner end surface 14 and the outer end surface 15 are arc structures. Both the inner end surface 14 and the outer end surface 15 are arc structures, which means the part between any two points on the circle. The inner end surface 14 and the outer end surface 15 have the same center of the circle. The hoop unit 1 of the present invention can adapt to a maximum pipe diameter of 1070mm and a minimum pipe diameter of 100mm. For the traditional chain structure hoop, the diameter corresponding to the arc of the hoop unit unit is too large, which cannot meet the installation requirements of small-diameter installation poles such as light poles. Especially in urban areas, the hoop is mainly installed on small-diameter poles. On the installation rod, the hoop unit with an excessive diameter cannot meet the installation requirements of small pipe diameters.

As a specific embodiment, both ends of the hoop unit 1 are arc structures. Specifically, both ends of the hoop unit 1 have a semicircular structure. The corresponding two ends of the hoop units 1 are arranged in an arc shape or a semicircular structure in order to leave a rotation space when the connected hoop units 1 rotate and ensure smooth rotation between the hoop units 1 .

As a specific embodiment, the inside of the lightening hole 13 is a curved surface structure, and the distances between the two sides of the lightening hole 13 and the corresponding end faces of the hoop unit 1 are equal. The distances between the two sides of the lightening hole 13 and the corresponding end faces of the hoop unit 1 are equal, which means that the distances between the two sides of the inside of the lightening hole 13 and the inner end face 14 and the outer end face 15 are equal, respectively, to ensure uniform wall thickness.

As a specific embodiment, the inner end surface 14 of the hoop unit is provided with a plurality of groups of grooves 141, and the grooves 141 are distributed at equal intervals. During assembly, a plurality of hoop units 1 are connected end to end to form a circle to form a chain-type quick clamp. When the chain-type quick clamp is installed on the mounting tower, the inner end surface 14 of the hoop unit with an anti-slip function fits with the mounting tower, increasing the friction between the hoop unit 1 and the mounting tower, preventing the hoop unit 1 from slipping and preventing strong winds from causing the hoop unit 1 to spin left and right. In this embodiment, the inner end surface 14 of the hoop unit 1 is provided with a groove structure. Of course, a protrusion may also be provided on the inner end surface, or the inner end surface 14 may be sandblasted to become a frosted surface, which helps prevent slipping. Specifically, when the inner end surface 14 of the hoop unit is a frosted surface, the frosted surface may be a diamond surface.

As a preferred solution, as shown in FIG. 5 , a plurality of hoop units 1 are connected through connection holes 11 to form a circle to form a hoop.

As a preferred solution, as shown in FIG. 3 , the hoop includes a first connecting piece 111 , and the hoop units 1 are cooperatively connected through the first connecting piece 111 and the connecting hole 11 . Fasteners such as bolts and pins are used to fasten the first connecting piece 111 and the hoop unit 1, so that the hoop unit 1 can be easily installed or disassembled. Specifically, two adjacent hoop units 1 are connected through two upper and lower first connecting parts 111. The connection between the upper and lower first connecting parts 111 makes the connection between the hoop units 1 tighter.

As a preferred solution, as shown in Fig. 4-8, the clamp has a locking mechanism 2, which includes a first locking member 21 and a second locking member 22, which are connected by a fastener, and the second locking member 22 includes a stopper 221, which has a through hole 225 and a groove 222, and the through hole 225 is located inside the groove 222. The fastener can be a bolt or a positioning pin. In this embodiment, a bolt is used for locking. The bolt 23 is inserted into the second locking member 22 and the first locking member 21 in sequence through the through hole 225, and the end of the bolt 23 is limited in the groove 222 to prevent the bolt from moving left and right, thereby improving the fastening. The stopper 221 is formed by cutting off a portion of a cylinder along the axial direction, the volume of the cut-off portion is smaller than the volume of the remaining portion, and then a groove 222 is opened along the cross section of the remaining portion to form the stopper 221.

As shown in FIG. 8 , the groove 222 passes through the stopper 221 in the axial direction. Groove 222 is a square groove. The through hole 225 is located at the center of the groove 222 and at the bottom of the groove 222. When the bolt 23 is inserted into the through hole 225 at the center of the groove 222 to lock the hoop, the tightening is more stable. The bolt 23 includes a nut 231 located inside the groove 222 , and the diameter of the nut 231 is adapted to the width of the groove 222 . The second locking member 22 includes a connecting block 226 , and the connecting block 226 has an arc-shaped surface that fits the stopper block 221 . As shown in FIG. 6 , the connecting block 226 has an oblong hole 224 . The oblong hole 224 allows the insertion gap of the bolt to be adjusted and provides a tensioning space for the hoop. The oblong hole 224 is a through hole with one side closed. The traditional long round hole has a notch on one side. Failure to tighten the bolts during the installation process will cause it to fall easily, which is dangerous when working at heights.

The first locking part 21 and the second locking part 22 are respectively connected to the hoop unit 1 through the second connecting part 223 to achieve locking between the locking mechanism and the hoop unit. The first locking member 21 also has a stopper block 221 and a connecting block 226. The stopper block 221 of the first locking member 21 is formed by cutting off part of the cylinder along the axial direction, and the volume of the cutout part is larger than the remaining part. Volume, the remaining part is the stop block 221, the stop block 221 has a through hole, but does not have a groove 222. The connecting block 226 has an oblong hole. Preferably, the end surfaces of the connecting blocks 226 of the first locking member 21 and the second locking member 22 are both provided with assembly holes 24 that cooperate with the second connecting member 223 . The assembly hole 24 is used for connecting the hoop unit 1 to the first locking part 21 and the second locking part 22 . In order to further change the encircling diameter of the hoop, the end surface of the connecting block 226 is provided with two assembly holes 24, and the second connecting piece 223 can be selectively fixed with one of the assembly holes 24.

As a preferred solution, both the first connecting member 111 and the second connecting member 223 are arc structures. The first connecting member 111 and the second connecting member 223 have the same center of circle as the hoop unit 1, and can form a complete circle when the hoop is assembled.

As a preferred solution, as shown in Figure 9, the hoop includes a support arm 16, and the support arm 16 includes a mounting plate 162. The mounting plate 162 is a straight plate, and the mounting plate 162 is provided with at least one pair of folds perpendicular to the mounting plate 162. The ear 161 has a first bolt hole 163 on the mounting plate 162, and the folding ear 161 has a second bolt hole 164. The folding ear 161 is fixed to the hoop unit 1 through the mounting hole 12, and the mounting plate 162 is used to install a load, such as an antenna device. The mounting plate 162 adopts a straight plate and can mount relatively large equipment. The support arm 16 is formed in one piece, and the folding ears 161 are formed by bending the support arm body, or the folding ears 161 are welded to the mounting plate 162 . The first bolt holes 163 are oblong holes, and the first bolt holes 163 are symmetrically arranged on both sides of the mounting plate 162 . The long round hole can be used to adjust the installation position of the equipment left and right to meet the installation requirements of the equipment at different angles. The edge of the folding ear 161 corresponding to the hoop unit 1 is arc-shaped, and the arc is consistent with the arc of the hoop unit 1. The curvature is consistent, which can ensure that the folding ear 161 does not affect the installation of the hoop on the pole. There is a pair of folding ears 161, which are arranged symmetrically up and down along the mounting plate 162. The folding ears 161 are located at the center line of the mounting plate 162. The folding ears 161 are symmetrically arranged and located at the center line of the mounting plate 162, which is beneficial to maintaining the stability of equipment installation. The folding ear 161 is fixed to the hoop unit 1 through fasteners such as bolts, and the upper and lower sides of the folding ear 161 are fixed to the hoop unit 1 to ensure the tight connection between the support arm 16 and the hoop. The second bolt holes 164 are symmetrically arranged on both sides of the folding ear 161 , and the second bolt holes 164 correspond to the mounting holes 12 one-to-one. The four corners of the mounting plate 162 are in the form of arc chamfers, mainly to keep the edges of the mounting plate 162 smooth and not sharp.
