Abstract
The utility model relates to a bidirectional ejection engineering support, belonging to a construction tool. The utility model comprises a sleeve and threaded rods screwed on the both ends of the sleeve, and the other end of the threaded rod which is not screwed with the sleeve is provided with a top board. The utility model having the characteristic of firmness and durability is made of the metal material; the utility model adopts a hollow pipe and a rotatory connecting structure, which ensures utility model provided with the advantages of light weight, easy mounting, portable conveying, etc. The utility model also has the advantages of turnover use, the adjusted length and the supporting plane direction, simple structure, convenient operation, stability and reliability.
Description
The utility model is that a kind of two-way engineering that ejects supports, and belongs to a kind of building appliance.
Existing building supports and generally all adopts log, and the volume of log is bigger, is difficult for carrying.And the quality of log itself has also determined the shortcoming that it is easily broken, easy to break.
The purpose of this utility model is: design a kind of easy operating, the reliable and stable two-way engineering that ejects supports.
The utility model comprises a sleeve pipe and the screw rod that spins with the sleeve pipe two ends, and screw rod does not have top board with the other end that sleeve pipe spins.The utility model can be made by metal material, and it has robust characteristics.And the utility model has adopted hollow tubing and the structure that spins to make it have advantage in light weight, that be easy to dismounting, be easy to carry again.
Said screw rod two ends are respectively left-handed and dextrorotation then can reach the purpose that the utility model extends and shortens by unidirectional rotation.
Top board adapts to different construction environments with screw rod by the hinged the utility model that can also make of a pin.
For making the utility model be easy to processing, it is connected the nut of screw rod by the two ends of sleeve pipe with sleeve pipe, and each nut is installed in the sleeve pipe by holding screw, and the inner of screw rod has back-up ring.
Each back-up ring is connected to the inner of corresponding screw rod by screw.
The inner face of nut and screw rod has buffer gasket or pad.
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Fig. 1 is the phantom of the utility model embodiment;
Wherein, 1-top board, 2-bearing pin, 3-screw rod, 4-nut, 5-buffer gasket, 6-back-up ring, 7-buffering spacer, 8-sleeve pipe.
Present embodiment is made up of sleeve pipe 8, two screw rods 3 that are installed on sleeve pipe 8 two ends and the top board 1 on the screw rod 3.Sleeve pipe 8 is a straight tube, respectively has an external surface to be step-like nut 4 at its two ends and is installed in the sleeve pipe 8 by the holding screw that passes sleeve pipe 8, has buffer gasket 5 on the inner face of nut 4.Two screw rods 3 spin with two nuts 4 respectively, and the screw thread of the nut 4 at two ends and screw rod 3 is reverse, promptly is respectively left-handed and dextrorotation.The end that screw rod 3 is positioned at sleeve pipe 8 has the buffering spacer 7 of back-up ring 6 and back-up ring 6 inboards by screw.The diameter of back-up ring 6 is greater than the diameter of screw rod 3.The outer end of each screw rod 3 is hinged with a lip-deep hole of top board 1 separately by bearing pin 2 respectively, has rough anti-skidding line on the external surface of top board 1.
The utility model can have enough to meet the need utilization, adjustable length and supporting surface direction, have simple in structure, Easy operating, reliable and stable characteristics.
