The utility model aims to provide a vacuum absorption fixing seat used for mounting and counterbalancing the communication antenna, which has the advantages of high turning torque resisting ability, firmer fixation and higher erected antenna height.
Description
Technical field
The utility model relates to a kind of communication antenna counterweight vacuum suction holder is installed.
Background technology
The existing support that is installed in the mobile communication antenna of roof equal-height position adopts the A-frame formula to come the counterweight antenna more, perhaps adopt pole grasp type to come the counterweight antenna, but because the project organization of counterweight is unreasonable, make that the anti-turning torque ability of support is big inadequately, the antenna height of antenna does not reach the ideal designs requirement.
The utility model content
The purpose of this utility model is to provide a kind of anti-turning torque ability big, and is fixing more firm, and the communication antenna that the antenna height that is set up is higher is installed counterweight vacuum suction holder.
Communication antenna of the present utility model is installed counterweight vacuum suction holder, comprise base, the lower surface of base is provided with the recessed recess that makes progress, the inner surface of recess is a semicircle sphere, the lower surface of base is provided with circular rubber blanket, the periphery of the recess company of subsides mutually on the edge of the upper surface of rubber blanket and the base lower surface, the lower surface of rubber blanket is provided with the chassis, the semicircle sphere of the upper surface on chassis for matching with the inner surface of described recess, the middle part of chassis upper surface vertically is provided with pull bar, pull bar is provided with screw thread, and pull bar is upward through described rubber blanket and described base, and the top that is positioned at base on the pull bar is installed with nut.
Communication antenna of the present utility model is installed counterweight vacuum suction holder, and the thickness of wherein said rubber blanket is 80-160mm, and the degree of depth of described recess is 80-300mm.
Communication antenna of the present utility model is installed counterweight vacuum suction holder, and wherein said base adopts cast iron or concrete to make, and described pull bar and described chassis adopt steel to make.
Communication antenna of the present utility model is installed counterweight vacuum suction holder, the lower surface of its base is provided with the recessed recess that makes progress, the inner surface of recess is a semicircle sphere, the lower surface of base is provided with circular rubber blanket, the periphery of the recess company of subsides mutually on the edge of the upper surface of rubber blanket and the base lower surface, the lower surface of rubber blanket is provided with the chassis, the semicircle sphere of the upper surface on chassis for matching with the inner surface of recess, the middle part of chassis upper surface vertically is provided with pull bar, pull bar is provided with screw thread, pull bar is upward through described rubber blanket and described base, and the top that is positioned at base on the pull bar is installed with nut.In use, the lower surface of rubber blanket can be pasted mutually with the installed surface of roof, utilize nut to screw pull bar then, the pull bar that moves upward can be with the chassis to move upward together, and the middle part of rubber blanket is pressed into the base lower surface place makes progress in the recessed recess, thereby the lower surface at rubber blanket forms a vacuum chamber, allows rubber blanket be adsorbed on the installed surface place of roof tightly, and then utilizes pull bar to link to each other with antenna holder.Owing to be to adopt vacuum suction to fix, therefore, it is big that communication antenna installation counterweight of the present utility model has anti-turning torque ability with the vacuum suction holder, fixing more firm, the characteristics that the antenna height that is set up is higher, and can not cause damage, can reduce maintenance cost the watertight composition of roof.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
Description of drawings
Fig. 1 is that communication antenna of the present utility model is installed the main pseudosection of counterweight with the structural representation of vacuum suction holder;
Fig. 2 installs the main pseudosection of counterweight with the structural representation that is in user mode of vacuum suction holder for communication antenna of the present utility model.
Embodiment
Referring to Fig. 1, communication antenna of the present utility model is installed counterweight vacuum suction holder, comprise base 1, the lower surface of base 1 is provided with the recessed recess 2 that makes progress, the inner surface of recess 2 is a semicircle sphere, the periphery of recess 2 is circular, the lower surface of base 1 is provided with circular rubber blanket 3, the periphery of recess 2 adopts the company of subsides mutually on the edge of the upper surface of rubber blanket 3 and base 1 lower surface, the form of the company of subsides can be bonding mutually, also can be riveted joint, the lower surface of rubber blanket 3 be provided with chassis 4, the semicircle sphere of the upper surface on chassis 4 for matching with the inner surface of recess 2, the middle part of chassis 4 upper surfaces vertically is provided with pull bar 5, pull bar 5 is provided with screw thread, and pull bar 5 is upward through rubber blanket 3 and base 1, and the top that is positioned at base 1 on the pull bar 5 is installed with nut 6.
The thickness of above-mentioned rubber blanket 3 can be 80-160mm, and the degree of depth of recess 2 is 80-300mm.
Above-mentioned base 1 can adopt cast iron or concrete to make, and pull bar 5 and chassis 4 can adopt steel to make.
As shown in Figure 2, communication antenna of the present utility model is installed counterweight with the vacuum suction holder in use, the lower surface of rubber blanket 3 can be pasted mutually with the installed surface of roof, installed surface should be a smooth even curface, installed surface can be a steel plate that is fixed on the roof, sheet materials such as aluminium sheet, utilize nut to screw pull bar 5 then, allow pull bar 5 move upward along vertical direction, the pull bar 5 that moves upward can be with chassis 4 to move upward together, the chassis that moves upward 4 can be pressed into the middle part of rubber blanket 3 base 1 lower surface place and make progress in the recessed recess 2, the lower surface of rubber blanket 3 then can upwards be heaved, thereby the lower surface at rubber blanket 3 forms a vacuum chamber, allow rubber blanket 3 be adsorbed on the installed surface place of roof tightly, and then utilize pull bar 5 to link to each other with antenna holder.
