Abstract
The invention relates to the technical field of mechanical accessories, in particular to a pretightening ejector rod. The pretightening ejector rod comprises a rod body, ejector headers and a locknut; the ejector headers are connected with two ends of the rod body; the locknut sheathes the middle part of the rod body; the end part of each ejector header is provided with an ejector plate and a torsional spring; each ejector header is rotatably connected with the corresponding ejector plate, and each torsional spring sheathes the corresponding ejector plate; an extrusion force can be exerted by matching with the locknut to implement pretightening, therefore structural stability is improved.
Description
Technical field
The present invention relates to mechanical attachment technical field, especially a kind of prefastening push rod.
Background technique
Push rod is conventional assistive device, for be supported on adjacent objects space between, play the effect applying pressure or hanging object.The top structure at existing push rod two ends is single, and self does not have squeeze function, and structure stability is poor.
Summary of the invention
Single in order to overcome existing push rod structure, the deficiency of poor stability, the invention provides a kind of prefastening push rod.
The technical solution adopted for the present invention to solve the technical problems is: a kind of prefastening push rod, comprise the body of rod, top and locking nut, top is connected to the two ends of the body of rod, and locking nut is enclosed within the middle part of the body of rod, top has been rotatably connected top board, and on top board, cover has torsion spring.
The invention has the beneficial effects as follows, top is rotatably connected top board, and is set with torsion spring on top board, can lock nut and play extruding force, implement pretension, improve structure stability.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. bodies of rod in figure, 2. come directly towards, 3. locking nut, 4. top board, 5. torsion spring.
Embodiment
If Fig. 1 is structural representation of the present invention, a kind of prefastening push rod, comprise the body of rod 1, top 2 and locking nut 3, top 2 is connected to the two ends of the body of rod 1, and locking nut 3 is enclosed within the middle part of the body of rod 1, and top 2 has been rotatably connected top board 4, and on top board 4, cover has torsion spring 5.
Top 2 is rotatably connected top board 4, and is set with torsion spring 5 on the top plate 4, can lock nut 3 and play extruding force, implements pretension, improves structure stability.
