Abstract
The utility model discloses a clamping structure used for fixing a screw on a ceiling. The clamping structure comprises a telescopic rod, a clamping head is fixed at the top end of the telescopic rod, a step hole is formed in the clamping head, and a rotating rod is arranged at the lower end of the telescopic rod. The telescopic rod comprises an upper portion rod body, a middle portion rod body and a lower portion rod body, wherein the upper portion rod body, the middle portion rod body and the lower portion rod body are sequentially connected. The diameter of the middle portion rod body is larger than that of the upper portion rod body and smaller than that of the lower portion rod body. With the structure, the clamping structure can fix the screw on the ceiling conveniently, improve safety of operators, and meanwhile reduce investment cost.
Description
Technical field
The utility model relates to the realm of building construction, specifically for screw rod being fixed on to the clamp structure on ceiling.
Background technology
In construction, in order to realize, corresponding passage, electrical equipment, ornament etc. are installed on ceiling, need to successively rule, hole, in boring, install the operations such as screw rod.Boring refers to processes the operation of portalling on solid material with drill bit, boring all relates in a lot of fields, such as house decoration, geologic prospect, engraving etc.
At present, because ceiling is generally not low apart from the height of bottom surface, while carrying out screw rod installation on ceiling, need to or directly take installing rack by mobile ladder, use mobile ladder to carry out screw rod while installing, need to move ladder to another place after completing a local installation, and then climb up the ladder, this mode efficiency is lower, and operating personnel also may, because slip up or surprisingly fall from ladder, bring the hidden danger of personal safety to operating personnel simultaneously; In addition, if adopt installing rack to carry out screw rod installation, need to build a large amount of installing racks, complete the installing rack of dismantling again after installation, adopt and carry out in this way screw rod installation, not only cost is higher, and builds and to remove and install frame more time-consuming.
Utility model content
The utility model provides for screw rod being fixed on to the clamp structure on ceiling, has solved the operation in the past screw rod being fixed on ceiling and has relatively bothered, and also may bring the problem of personal safety hidden danger to operating personnel.
The utility model is that technical solution problem is achieved through the following technical solutions: for screw rod being fixed on to the clamp structure on ceiling, comprise expansion link, the top of described expansion link is fixed with chuck, and described chuck is provided with stepped hole, and the lower end of described expansion link is provided with bull stick.Chuck is for inserting screw rod to be installed, and stepped hole is combined for the accessory on screw rod, prevents that screw rod from skidding when installing; By bull stick, realize the rotation of expansion link, the screw rod being fixed in chuck is screwed in the hole on ceiling, realize the fixed installation of screw rod.
Further, described expansion link comprises the top body of rod, the middle part body of rod and the bottom body of rod connecting successively, and the diameter of the described middle part body of rod is greater than the diameter of the top body of rod, and the diameter of the middle part body of rod is less than the diameter of the bottom body of rod.The structure of expansion link is relatively existing, a common technology to one skilled in the art, and its principle is the same with the expansion link of umbrella, and main purpose is to be convenient to extend and shrink, and conveniently works and carries.
Further, the top of described expansion link is provided with external screw thread, and the bottom of chuck is provided with tapped fixing hole, and chuck is fixed on expansion link by this fixing hole.After adopting between chuck and expansion link and being threaded, can facilitate the replacing of chuck.
Further, the shape of cross section of the macropore of described stepped hole is regular polygon.
Further, described bull stick is mutually vertical with expansion link.
Further, the length of described bull stick is 30 ~ 50cm.
Further, the shape of cross section of described chuck is circular, and the central axis of chuck and the central shaft of expansion link are to overlapping.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) mode that the utility model adopts expansion link to combine with chuck realizes the fixed installation of screw rod on ceiling, mobile ladder and installing rack before having replaced, not only make screw rod install and become convenient, operating personnel only need stand can realize operation installation on the ground, also the security that has improved operating personnel, has also reduced cost input on the other hand.
(2) the utility model overall structure is simple, easy operating and realization, and practicality is stronger, easy to utilize.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
The specific embodiment
