Abstract
The utility model provides a telescopic ejector rod. The telescopic ejector rod comprises a sleeve with the inner surface provided with threads, the threads in the sleeve extend to the two ends from the middle so that two segments of reverse threads can be formed, the two ends of the sleeve are respectively provided with an ejector rod body in a sleeved mode, the outer surface of each ejector rod body is provided with external threads matched with the threads in the sleeve, and rotating holes are further formed in the wall of the middle of the sleeve. The telescopic ejector rod is simple in structure, the ejector rod bodies at the two ends of the sleeve can fast abut against rib plates or longitudinal and transverse walls to be welded by rotating the sleeve, movement or deformation is prevented, cost is low, and the telescopic ejector rod can be reused and very convenient to use.
Description
Technical field
The utility model relates to a kind of Extendible knockout pin.
Background technology
when the segmented assemblies of hull is manufactured, welding is a most general procedure, and the floor length of hull is longer, when welding, in order to prevent, is out of shape or slippage, need to floor be reinforced or be shaped, therefore need some to support head part, yet existing method adopts some rod members mostly, length is as required cut, during work, also need the methods such as cushioning, consumptive material is very large like this, and cost is high, and not reproducible utilization and efficiency are lower.
Summary of the invention
The utility model improves the problems referred to above, and the technical problems to be solved in the utility model is that the not reproducible utilization of existing supporting post-rod and efficiency are lower, and cost is high, and waste of material is serious.
Specific embodiments of the present utility model is: a kind of Extendible knockout pin, comprise that an inside face establishes threaded sleeve pipe, screw thread in described sleeve pipe is extended to form two sections of reverse threads to two ends by middle part, described sleeve pipe two ends are respectively arranged with a push rod, push rod outside face has the outside thread matching with screw thread in sleeve pipe, on the tube wall at described sleeve pipe middle part, is also provided with rotation hole.
Further, one end that described push rod stretches out outside sleeve pipe is connected with top board.
Compared with prior art, the utlity model has following beneficial effect: the utility model is simple in structure, by rotating casing, the push rod at two ends can be supported fast to floor to be welded or wall in length and breadth, prevent mobile or distortion, cost is low, can reuse, very convenient.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, a kind of Extendible knockout pin, comprise that an inside face establishes threaded sleeve pipe 10, screw thread in described sleeve pipe 10 is extended to form two sections of reverse threads to two ends by middle part, described sleeve pipe 10 two ends are respectively arranged with a push rod 20, push rod outside face has the outside thread 210 matching with screw thread in sleeve pipe, on the tube wall at described sleeve pipe middle part, is also provided with rotation hole 110.During use, axis body can be goed deep into, in the rotation hole 110 at middle part, realize laborsaving rotation.One end that push rod 20 stretches out outside sleeve pipe is connected with top board 30.Top board 30 is formed in one or welds with push rod 20, and top board is also replaceable for other shapes are to adapt to different support surfaces.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
