The existing chained quick anchor ear comprises a locking mechanism and a plurality of anchor ear units, the anchor ear units are connected end to end and are installed on an installation tower, and the anchor ear is locked through the locking mechanism. By adding or subtracting hoop units, the installation requirements of different types and sizes of installation towers can be met. The chain type quick anchor ear generally has a structure for connecting the support arms, the support arms are used for fixing the holding pole, and the holding pole is used for installing the antenna equipment.
The traditional hoop unit is provided with a mounting hole for connecting the support arm on the outer wall of the hoop unit, in fact, the weight of the antenna equipment is concentrated at the joint of the hoop unit and the mounting hole, if the welding between the mounting hole and the hoop unit is unstable, the weight of the antenna equipment is very easy to cause the bearing of the hoop unit to be unstable, and the mounting hole is easy to fall off.
As shown in fig. 1-5, the invention adopts a chain type quick anchor ear, the anchor ear comprises a plurality of arc-shaped anchor ear units 1 which are connected end to end, the anchor ear units 1 are solid bodies, mounting holes 12 and a pair of connecting holes 11 which are symmetrically arranged at the head and the tail of the anchor ear units are arranged in the anchor ear units 1, the mounting holes 12 are arranged between the two connecting holes 11, and all the mounting holes 12 and the connecting holes 11 on the anchor ear are positioned on the same circle. The holes for connection between the hoop units are used as connection holes 11, the holes for mounting the load are used as mounting holes 12, and the load is the antenna device. All mounting holes 12 and connecting holes 11 on the anchor ear are located on the central circumferential line of the anchor ear unit 1.
The connecting hole 11 is arranged in the hoop unit 1, so that the condition that the connecting hole 11 falls down is effectively avoided. Moreover, the weight of the antenna device is dispersed over the whole of the cuff unit 1, greatly increasing the load bearing capacity and the safety protection of the cuff unit 1. The mounting holes 12 and the connecting holes 11 are arranged on the same circle, the bolt stress in the connecting holes 11 and the bolt stress in the mounting holes 12 are transferred to the hoop unit 1, and the stress is dispersed by utilizing the rigidity of the hoop unit 1, so that the bearing effect and the safety are greatly improved, and the mounting capacity and the service life of the hoop are improved.
In this embodiment, the hoop unit 1 adopts a solid structure, the mounting hole 12 is in solid connection with the connecting hole 11, the strength of the hoop unit 1 is higher, and the antenna device is safe and reliable to mount and is not affected by external force.
In this embodiment, the mounting hole 12 and the connecting hole 11 of the hoop unit 1 are formed in the form of holes, and the hoop unit 1 is integrally formed without welding points, so that the strength and the corrosion resistance are stronger.
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, the hoop unit 1 is internally provided with a pair of mounting holes 12. The connection holes 11 are symmetrically arranged to facilitate the stability of the connection between the tag units 1, and the mounting holes 12 are symmetrically arranged to further facilitate the stability of the antenna device when mounted.
As a specific example, the hoop unit 1 is provided with a lightening hole 13 at a central position, and the lightening hole 13 is located on a circle where the mounting hole 12 and the connection hole 11 are located. The conventional hoop unit 1 adopts a structure in which the inside is almost hollow, and the main purpose is to reduce the dead weight, but the strength problem of the hoop unit 1 itself is neglected while reducing the dead weight. The hoop unit 1 needs to bear the weight of the antenna device, and the weight of the antenna device is determined according to the situation, if the weight of the antenna device is far greater than the strength that the hoop unit 1 can bear, the hoop unit 1 is easy to damage, the antenna device is easy to drop, not only the material equipment is damaged, but also the resource waste is caused, and the potential safety hazard is easy to cause. Some of the hoop units 1 have an internal hollowed-out structure, and then reinforcing ribs are arranged inside the hoop units 1 to strengthen the bearing of the hoop units 1, but the strength of the hoop units 1 is reduced due to excessive hollow structures. If the whole hoop unit 1 is of a solid design, the weight of the hoop unit itself is necessarily increased greatly, and the hoop needs to be carried when the tower is installed, and the carrying is extremely inconvenient because of the large weight, and if the inside of the hoop unit 1 is mostly of a hollow design, it is obvious that the strength of the hoop unit 1 is also greatly reduced although the weight of the hoop unit is reduced. Therefore, the hoop unit 1 is of a partially hollow structure, so that the dual requirements of reducing the self weight and guaranteeing the self strength are met, the toughness and the plasticity of the hoop unit 1 are improved, and the stress of the hoop unit 1 is uniformly dispersed when the support arms are connected. Meanwhile, the weight reducing hole 13 is arranged at the center of the hoop unit 1, so that the stability of the hoop unit 1 under stress is ensured.
As a specific example, the hoop unit 1 has an inner end face 14 and an outer end face 15, and the inner end face 14 and the outer end face 15 are each of a circular arc structure.

The hoop unit 1 of the present invention can accommodate 1070mm of maximum pipe diameter and 100mm of minimum pipe diameter. For the staple bolt of traditional chain structure, the diameter that the circular arc of its hoop unit corresponds is too big, can't satisfy the installation of little pipe diameter erection pole like the lamp pole, especially in urban area, the staple bolt is mainly installed on the erection pole of little pipe diameter, and the installation requirement of little pipe diameter can't be satisfied to the oversized hoop unit of diameter.
As a specific example, both end portions of the hoop unit 1 have a circular arc structure. Specifically, the two ends of the hoop unit 1 have a semicircular structure. The corresponding two ends of the hoop units 1 are arranged into arc-shaped or semicircular structures, so that a rotating space is reserved when the connected hoop units 1 rotate, and smooth rotation between the hoop units 1 is ensured.
As a specific embodiment, the inside of the lightening hole 13 is in a curved surface structure, and the distances between the two sides of the lightening hole 13 and the corresponding end face of the hoop unit 1 are equal. The equal distance between the two sides of the lightening hole 13 and the corresponding end surface of the hoop unit 1 means that the equal distance between the two sides of the interior of the lightening hole 13 and the inner end surface 14 and the outer end surface 15 respectively ensures that the wall thickness is uniform.
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 the equipment, a plurality of hoop units 1 end to end encloses into the round, constitutes the swift staple bolt of chain, when installing the swift staple bolt of chain on the erection tower, has the laminating of anti-skidding effect's hoop unit inner end face 14 and erection tower, increases the frictional force with between the erection tower, prevents hoop unit 1 landing and prevents that strong wind from influencing and turn around.
