Referring to fig. 1 to 4, the clamp 81 includes a first clamp member 10 and a second clamp member 20, the first and second clamp members 10 and 20 sandwich the angle tower body 30, and the first and second clamp members 10 and 20 are connected by a locking member 40. The angle tower body 30 is generally a long steel strip with two perpendicular sides and an angle shape, and the lengths of the two sides of the long steel strip selected on the angle tower are generally the same. Specifically, the first hoop member 10 is installed on the inner side of the angle tower body 30, the second hoop member 20 is installed on the outer side of the angle tower body 30, the first hoop member 10 and the second hoop member 20 are of a double-layer structure, and the double-layer structure can enable the first hoop member 10 and the second hoop member 20 to be stably installed on the angle tower body 30. If the first and second clip members 10 and 20 have a single-layer structure, the first and second clip members 10 and 20 need to have a sufficient thickness in order to ensure stability after installation. Referring to fig. 5, the first collar member 10 having a single-layer structure is shown in the drawing, and compared to the first collar member 10 having a double-layer structure shown in fig. 2, the first collar member 10 having a single-layer structure requires more materials for manufacturing, has high manufacturing cost, heavy parts, and is inconvenient to carry, and in an actual installation test, the effect of the first collar member 10 having a single-layer structure after being installed on the body 30 of the angle iron tower is substantially the same as that of the first collar member 10 having a double-layer structure, so the first collar member 10 and the second collar member 20 preferably have a double-layer structure.

The first clip member 10 includes a first mounting plate 11, a second mounting plate 12, and a first connecting plate 13, the first connecting plate 13 connecting the first mounting plate 11 and the second mounting plate 12; the second clip member 20 includes a third mounting plate 21, a fourth mounting plate 22, and a second connecting plate 23, and the second connecting plate 23 connects the third mounting plate 21 and the fourth mounting plate 22. The locking member 40 connects the first connecting plate 13 and the second connecting plate 23, so that the first hoop member 10 and the second hoop member 20 sandwich the angle-steel tower body 30. As a further preferred scheme, the first mounting plate 11 and the second mounting plate 12 are the same in shape, the third mounting plate 21 and the fourth mounting plate 22 are the same in shape, the first connecting plate 13 is perpendicular to the plane of the first mounting plate 11 and the second mounting plate 12, and the second connecting plate 23 is perpendicular to the plane of the third mounting plate 21 and the fourth mounting plate 22. When the clamp 81 is mounted on the angle tower body 30, the first mounting plate 11 and the second mounting plate 12 on the first clamp 10 are abutted against the inner side of the angle tower body 30, and the third mounting plate 21 and the fourth mounting plate 22 on the second clamp 20 are abutted against the outer side of the angle tower body 30.

The clamping force between the clamp 81 and the angle steel tower body 30 is reserved to the maximum extent, so that the maximum friction force of the clamp 81 when sliding on the angle steel tower body 30 is improved, and the clamp 81 is not easy to slide after being connected to the angle steel tower body 30.

In some other embodiments, the first and second clip members 10 and 20 can also be a multi-layer structure, for example, three or more layers. The first and second ferrule members 10 and 20 having the three-layer structure can achieve similar effects to the first and second ferrule members 10 and 20 having the two-layer structure when they are mounted. However, in the factory processing process, the first clamp member 10 and the second clamp member 20 with the double-layer structure can be formed (sheet metal parts) by sheet metal stamping and bending, and the processing is easy and the processing cost is low; however, in general, the three-layer structure cannot be directly processed by a sheet metal process, and a casting mold mode is selected, so that the processing is complicated, and the processing cost is high. Therefore, the first clip member 10 having a two-layer structure is preferable in the case where the difference in performance is not large, and cost saving can be achieved.

Preferably, the first mounting plate 11 is connected to the second mounting plate 12 through two first connecting plates 13, and the third mounting plate 21 is connected to the fourth mounting plate 22 through two second connecting plates 23. Correspondingly, at least two or more than three locking members 40 are arranged for connecting the first connecting plate 13 and the second connecting plate 23, and at least one locking member 40 is arranged between each first connecting plate 13 and the second connecting plate 23. The locking member 40 can enable the first hoop member 10 and the second hoop member 20 to be fixed on the angle steel tower body 30 in a balanced mode, and the situation that one side of the first hoop member is fixed tightly and one side of the second hoop member is fixed loosely cannot occur.

Preferably, referring to fig. 2, the first connecting plate 13 is provided with a first connecting hole 14, the second connecting plate 23 is provided with a second connecting hole 24, and the first collar member 10 and the second collar member 20 can be connected by passing bolts and nuts through the first connecting hole 14 and the second connecting hole 24. This connection has an advantage that the bolt and the nut can be tightened easily, and the first clip member 10 and the second clip member 20 can be fixed firmly by tightening the bolt and the nut. In some other embodiments, the first clamp member 10 and the second clamp member 20 can be connected by passing the cable tie through the first connecting hole 14 and the second connecting hole 24, the cable tie can be made of steel cable tie, the connection method has the advantages of quick fixation, but has the defects of difficult tightening, and therefore the fixation is weaker than bolt and nut. The clamp 81 is fixed on the angle tower body 30, and the primary purpose is to fix firmly, therefore, in the present invention, the connection mode of bolt and nut capable of tightening is preferred, and the locking member 40 comprises a bolt 41, a flat gasket 42, a spring gasket 43 and a first nut 44. Certainly, according to the difference of application scenario, retaining member 40 can choose some other commonly used connection modes for use, and does not make clear limitation to the selection of connection mode the utility model discloses.

Preferably, referring to fig. 2 and 3, the first mounting plate 11 is provided with a first mounting surface 15 and a second mounting surface 16 which contact the angle steel tower body 30, the third mounting plate 21 is provided with a third mounting surface 25 and a fourth mounting surface 26 which contact the angle steel tower body 30, (the first mounting plate 11 and the second mounting plate 12 have the same shape, the second mounting plate 12 is also provided with the first mounting surface 15 and the second mounting surface 16 which contact the angle steel tower body 30, the third mounting plate 21 and the fourth mounting plate 22 have the same shape, the fourth mounting plate 22 is also provided with the third mounting surface 25 and the fourth mounting surface 26 which contact the angle steel tower body 30), the first mounting surface 15 and the second mounting surface 16 contact the inner side of the angle steel tower body 30, and the third mounting surface 25 and the fourth mounting surface 26 contact the outer side of the angle steel tower body 30. Because two sides of the angle steel tower body 30 are perpendicular to each other, in order to enable the first clamp member 10 and the second clamp member 20 to be well mounted on the angle steel tower body 30, the first mounting surface 15 and the second mounting surface 16 form an angle of 90 degrees, and the third mounting surface 25 and the fourth mounting surface 26 also form an angle of 90 degrees, so that the first clamp member 10 and the second clamp member 20 can be just attached to the angle steel tower body 30.

Further, when the angle between the first mounting surface 15 and the second mounting surface 16 and the angle between the third mounting surface 25 and the fourth mounting surface 26 are 90 degrees, respectively. After being fixed in angle steel tower body 30 with clamp 81, the clamp force between first clamp 10 and the second clamp 20 is controlled by retaining member 40, because first clamp 10, second clamp 20 can laminate with angle steel tower body 30 just, after first clamp 10, the laminating of second clamp 20, because the laminating is inseparable, do not have the space of moving, installer just can't or hardly rotate first nut 44 again. At this time, the first nut 44 is fixed to the bolt 41 by the repulsive force generated by the spring washer 43 when tightened, but such connection is not firm. Since the conventional spring washer 43 will adapt to the deformation in the tightened state after a while, resulting in a reduction of the generated resilience, the first nut 44 will loosen, which indirectly results in the first and second clamp members 10, 20 not being able to clamp the angle tower body 30 tightly, and if the weight of the equipment installed on the device is heavy, the clamp 81 may slide down along the angle tower body 30 along with the equipment.

In order to ensure that the clamp 81 and the equipment thereon are not loosened after being mounted on the angle steel tower body 30 for a long time, the clamp 81 can still be firmly fixed on the angle steel tower body 30 without sliding downwards. The adopted technical scheme is as follows: when the clamp 81 is completely fixed to the turret body 30, the locking member 40 elastically deforms the first clamp member 10 or the second clamp member 20. Specifically, in this embodiment, referring to fig. 3, mainly let first clamp member 10 produce elastic deformation, first mounting panel 11 is last to be equipped with breach 17 with angle steel tower body 30 contact one side, breach 17 is the horn shape, breach 17 divides first clamp member 10 into for two parts about, makes first clamp member 10 have the ability of warping to breach 17 direction, and the bight position of breach 17 is equipped with first round hole 18 simultaneously, and first round hole 18 makes first clamp member 10 be difficult to break in the bight position of warping in-process breach 17. Meanwhile, an arc 19 is arranged on one side, far away from the angle steel tower body 30, of the first mounting plate 11, the opening back of the arc 19 is opposite to the position of the angle steel tower body 30 (the opening direction of the arc 19 is opposite to that of the notch 17), the length of one side, far away from the angle steel tower body 30, of the first mounting plate 11 is prolonged by the arc 19, and one side, far away from the angle steel tower body 30, of the first clamping hoop part 10 on the first mounting plate 11 in the deformation process cannot be broken due to stretching. As a further preferred solution, the angle between the first mounting surface 15 and the second mounting surface 16 is in the interval of 80 ° to 90 °, preferably 85 °; the third mounting surface 25 and the fourth mounting surface 26 form an angle of 90 °, and the notch 17 forms an angle in the interval of 60 ° to 120 °, preferably 90 °. Although the first collar member 10 cannot be completely attached to the angle tower body 30 in an undeformed state, the first collar member 10 is elastically deformed after the first collar member 10 and the second collar member 20 are completely attached to the angle tower body 30 by tightening the locking member 40, and at this time, the included angle formed between the first mounting surface 15 and the second mounting surface 16 is 90 degrees, and the first mounting surface 15 and the second mounting surface 16 are completely attached to the inner side of the angle tower body 30. In this state, since the first clip member 10 is elastically deformed, the first clip member 10 transmits an elastic force to the first nut 44 in the locking member 40, and the elastic force generated by the first clip member 10 is much greater than the resilient force generated by the spring washer 43, so that the first nut 44 is firmly fixed to the bolt 41 and is hard to be loosened after being fixed for a long time. In addition, the clamping force transmitted to the angle steel tower body 30 by the first clamp member 10 and the second clamp member 20 in the deformed state is also larger than the clamping force when the first clamp member 10 is not deformed, so that the maximum friction force of the clamp 81 in sliding on the angle steel tower body 30 can be improved, and the bearing capacity of the clamp 81 is increased. In the deformation process of the first hoop member 10, the first hoop member 10 transmits a part of force to the second hoop member 20 through the locking member 40, the second hoop member 20 may also deform, and in order to avoid the fracture at the boundary position between the third mounting surface 25 and the fourth mounting surface 26 on the second hoop member 20, a second round hole 27 is formed at the corner position of the contact side of the third mounting plate 21 and the angle tower body 30. It should be noted that even if the second clip member 20 is deformed, the deformation degree is slight because the included angle formed by the third mounting surface 25 and the fourth mounting surface 26 is 90 °, the second clip member 20 is already attached to the angle-steel tower body 30, and the deformation space is insufficient.

Preferably, in some other embodiments, the second clip member 20 can be deformed to fix the clip firmly. The angle formed between the first mounting surface 15 and the second mounting surface 16 is 90 °, and the angle formed between the third mounting surface 25 and the fourth mounting surface 26 is in the interval of 90 ° to 100 °, preferably 95 °. In some other embodiments, the first clip member 10 and the second clip member 20 are deformed together to fix the clip 81 firmly. The included angle formed between the first mounting surface 15 and the second mounting surface 16 is in the range of 80-90 degrees, and preferably 85 degrees; the third mounting surface 25 and the fourth mounting surface 26 form an angle in the interval of 90-100 degrees, preferably 95 degrees.
