Abstract
The invention discloses a fastening screw of a satellite base. The fastening screw comprises a screw body, an upper fixing ring and a lower fixing apparatus. The screw body comprises an upper section with a diameter A and a lower section with a diameter B, and the diameter A is larger than the diameter B; the upper fixing ring is fixed to the upper section in a threaded manner; the lower fixing apparatus comprises a plurality of support rods and an ejecting screw, a threaded through hole is formed in the middle of the screw body, the support rods are annularly arranged at the end of the lower section of the screw body, are rotationally connected with the screw body and comprise extending sections and expanding sections, the expanding sections are positioned in the through hole, the extending sections extend towards the outside of the screw body, and included angles between the expanding sections and the extending sections are smaller than 180 degrees and larger than 90 degrees; the ejecting screw is mounted in the through hole.
Description
Technical field
This explanation relates to a kind of satellite pedestal fastening screw trip bolt, belongs to satellite fitting seat field.
Background technique
Traditional satellite fastening screw trip bolt is only fixed for single screw, and need to be frequent carry out is fastening, and poor stability, connects insecure.
Summary of the invention
The technical problem that this explanation will solve is: overcome prior art Satellite fastening screw trip bolt and connect unstable technical problem, a kind of dual fixing satellite pedestal fastening screw trip bolt is provided.
The technical solution adopted for the present invention to solve the technical problems is:
A satellite pedestal fastening screw trip bolt, comprises screw body, top retaining ring and bottom fixture;
Described screw body comprises that diameter is the upper segment of A and the lower section that diameter is B, and described diameter A is greater than diameter B;
Described top retaining ring is fixed on upper segment by screw thread;
Described bottom fixture comprises some struts and top pressure screw rod, described screw body middle part arranges threaded penetration hole, described strut annular array is arranged in the end of screw body lower section, described strut and screw turns are rotationally connected, described strut comprises extension and expansion arc, described expansion arc is positioned at penetration hole, and extend towards the outside of screw body described extension, and the angle between described expansion arc and extension is less than 180 ° and is greater than 90 °;
Described top presses screw rod to be arranged in described penetration hole.
As the further innovation of this explanation, described top presses screw rod towards a side of upper segment, to be provided with the through hole of hexagonal prism structure.
The beneficial effect of this explanation is:
this explanation coordinates by the retaining ring on top and the expansion strut of bottom, has improved the stability of installing.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this explanation is further illustrated.
Fig. 1 is the structural representation of this explanation.
Embodiment
By reference to the accompanying drawings this explanation is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and the basic structure of this explanation is only described in a schematic way, so it only shows with this relevant formation is described.
As shown in Figure 1, be originally illustrated as a kind of satellite pedestal fastening screw trip bolt, comprise screw body, top retaining ring 2 and bottom fixture; Screw body comprises that diameter is the upper segment 3 of A and the lower section 5 that diameter is B, and diameter A is greater than diameter B; Top retaining ring 2 is fixed on upper segment 3 by screw thread; Bottom fixture comprises some struts 1 and top pressure screw rod 4, screw body middle part arranges threaded penetration hole, strut 1 annular array is arranged in the end of screw body lower section 5, strut 1 is rotationally connected with screw turns, strut 1 comprises extension and expansion arc, expansion arc is positioned at penetration hole, and extend towards the outside of screw body extension, and the angle between expansion arc and extension is less than 180 ° and is greater than 90 °; Top presses screw rod 4 to be arranged in penetration hole;
Top presses screw rod 4 towards a side of upper segment 3, to be provided with the through hole of hexagonal prism structure;
First top retaining ring is fixed in screw body, then screw is installed in mounting hole, rotate subsequently top and press screw rod, by top, press screw rod that strut is opened, subsequently by top retaining ring, tension strut, realizes fixing.
Take the above-mentioned desirable embodiment according to this explanation as enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this explanation technological thought, carry out various change and modification completely.The technical scope of this explanation is not limited to the content on specification, must determine its technical scope according to claim scope.
