Embodiment Construction

[0017] Below by specific embodiment the present invention is described in further detail:

[0018] see figure 1 , which is a structural schematic diagram of a preferred embodiment of the new adjustable pull rod of the present invention. In this embodiment, the novel adjustable pull rod includes a round pipe pull rod 1 , a pair of rod end joints, a pair of stoppers 2 and a pair of sleeves 3 . Wherein, the round tube pull rod 1 is made of HB8225, and its two ends are connected and fixed with the sleeve 3 through the rivet 4 . The sleeve 3 is used for the transition between the round pipe pull rod 1 and the double ear joint 5, and the sleeve 3 is provided with internal threads, and the internal threads of the sleeve 3 located at both ends of the round pipe pull rod 1 are respectively left or right. thread. One end of the rod end joint is a lug joint 5, and the other end is a screw 6 with an external thread. The transition zone at the root of the screw 6 is provided with six cl...

Abstract

The invention relates to a novel adjustable pull rod, in particular to a pull rod with adjustable length which is used for transmitting axial load. The novel adjustable pull rod comprises a circular-tube pull rod, a pair of rod-end connectors and a pair of stoppers, wherein, one end of the rod-end connector is of single-lug connector or double-lug connector, the other end is of a threaded rod with outer threads, the root transition area of the threaded rod is provided with connector clamp grooves which are evenly distributed at circumference direction. Both ends of the circular-tube pull rod are respectively provided with a pair of sleeves, the end part of the sleeve is connected with the threaded-rod threads of the rod-end connector, the sleeve is provided with a plurality of sleeve clamp grooves, and the stoppers are sleeved between the double-lug connector and the sleeve. The advantages of the invention are as follows: the adjustable pull rod provided by the invention has simple structure; through arranging the stopper between the double-lug connector and the circular-tube pull rod sleeve, when the length is adjusted, the two rod-end connectors are fixed, the length can be adjusted through rotating the circular-tube pull rod between the two rod-end connectors, only the length of the pull rod needs to adjust, therefore, the adjustment of the length of the pull rod can be conveniently and rapidly realized.

Description

technical field [0001] The invention relates to a pull rod, in particular to a pull rod with adjustable length for transmitting axial load. Background technique [0002] Tie rods are typical force-bearing components that mainly transmit axial loads, and are widely used in aircraft structural design, especially in mechanical control systems and door control systems. [0003] Usually the prior art pull rod is made up of two pull rod joints, two flat nuts, two stop washers, two fuses and a pipe with internal thread at both ends. Wherein, two tie rod joints are respectively arranged at both ends of the pipe with internal threads, and are locked by flat nuts, stop washers and fuses. The stop method of this connection uses the method of stop washer and fuse to ensure that there is no relative movement between the pull rod and the thread of the tie rod joint. This stop method is widely used, and the used nuts, stop washers and fuses are common standard parts, do not need special ...
