Description
Technical field
This utility model belongs to broadcast technology field, is specifically related to a kind of antenna feeder and safeguards Special ladder combiner.
Background technology
Safeguarding industry at broadcast antenna, bamboo ladder is common tool. General standby bamboo ladder length is about 6 meters, and maintenance work o'clock is often in 8 meters of level above, and tradition settling mode is, with iron wire, two bamboo ladders merging are tightened use. Because iron wire intensity is uncertain, and improving bud grafting not science, very easily cause bamboo ladder colligation insecure and cause that accident occurs.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, thering is provided a kind of antenna feeder to safeguard Special ladder combiner, two ladders can be combined by firmly, easy installation and removal, can Reusability, be greatly improved safety coefficient.
This utility model be the technical scheme is that a kind of antenna feeder safeguards Special ladder combiner, including the fixing plate of the fixing plate in the left side being hinged and right side, the active side of the fixing plate in described left side is provided with the fixing cylinder in left side, the fixing plate in described right side is two pieces that front and back are symmetrical independent, the active side of the fixing plate in these two pieces of right sides is provided with the fixing cylinder in right side, the fixing cylinder of the fixing cylinder in described left side and described right side is all be hinged by left and right two and the semicircle shape hoop shell of symmetrical coupling is constituted, and left and right two halves round shape hoop shell is provided with securing member, it is respectively arranged with a standing screw between the fixing plate of two blocks of fixing plates in right side and described left side.
As preferably, the securing member on the two halves round shape hoop shell of left and right is fastening bolt.
As preferably, the medial surface of described semicircle shape hoop shell is provided with rubber buffer, and this rubber buffer is provided with antislip cog.
As preferably, fixing the spacing between cylinder more than 5 centimetres on the right side of in the of two, and the opposing end face fixing cylinder on the right side of in the of two is concordant with the both ends of the surface of the fixing cylinder in described left side respectively.
The beneficial effects of the utility model are in that: owing to this utility model adopts said structure, at needs to when safeguarding that ladder lengthens, fixing for left side cylinder is fixed therein one and safeguards on ladder, it is fixed on another safeguards on ladder by fixing cylinder on the right side of two again, right side adopts two fixing cylinders perfect can solve the problem that step disturbs, then position again through standing screw, it is possible to prevent from occurring fixing between cylinder during work relatively rotating, it is to avoid the problem that de-stabilising effect uses; Use combiner of the present utility model, it is possible to safeguard that ladder combines by two firmly, mount and dismount all extremely convenients, can Reusability, be greatly improved safety coefficient.
Accompanying drawing explanation
Fig. 1 is structural representation one of the present utility model.
Fig. 2 is structural representation two of the present utility model.
Fig. 3 is use schematic diagram of the present utility model.
In figure: 1, the fixing plate in left side; 2, the fixing plate in right side; 3, the fixing cylinder in left side; 4, the fixing cylinder in right side; 5, standing screw.
Detailed description of the invention
Below in conjunction with the accompanying drawings and the specific embodiments this utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of antenna feeder safeguards Special ladder combiner, including the fixing plate 2 of the fixing plate 1 in the left side being hinged and right side, the active side of the fixing plate 1 in described left side is provided with the fixing cylinder 3 in left side, the fixing plate 2 in described right side is two pieces that front and back are symmetrical independent, the active side of the fixing plate 2 in these two pieces of right sides is provided with the fixing cylinder 4 in right side, the spacing between cylinder 4 is fixed more than 5 centimetres on the right side of in the of two, and it is concordant with the both ends of the surface of the fixing cylinder 3 in described left side respectively to fix the opposing end face of cylinder 4 on the right side of in the of two, it is respectively arranged with a standing screw 5 between the fixing plate 1 of two blocks of fixing plates 2 in right side and described left side.
The fixing cylinder 4 of the fixing cylinder 3 in described left side and described right side is all be hinged by left and right two and the semicircle shape hoop shell of symmetrical coupling is constituted, and left and right two halves round shape hoop shell is provided with securing member, this securing member is fastening bolt, the medial surface of described semicircle shape hoop shell is provided with rubber buffer, the covering property making fixing cylinder is better, adapts to different size and safeguards the needs of ladder, this rubber buffer is provided with antislip cog, the non-skid property making fixing cylinder is better, further increases safety coefficient.
Owing to this utility model adopts said structure, at needs to when safeguarding that ladder lengthens, as shown in Figure 3, fixing for left side cylinder 3 being fixed therein one and safeguards on ladder, then be fixed on another safeguard on ladder by fixing cylinder 4 on the right side of two, right side adopts two fixing cylinders can the perfect problem solving step interference, fixed effect is better simultaneously, then position again through standing screw 5, it is possible to prevent from occurring fixing between cylinder during work relatively rotating, it is to avoid the problem that de-stabilising effect uses; Use combiner of the present utility model, it is possible to safeguard that ladder combines by two firmly, mount and dismount all extremely convenients, can Reusability, be greatly improved safety coefficient.
The above, it is only this utility model preferred embodiment, therefore can not limit, with this, the scope that this utility model is implemented, the equivalence namely made according to this utility model claim and description changes and modifies, and all should still belong in the scope that this utility model patent contains.
