Abstract
An adjustable pull rod comprises a rod body I, a rod body II and a length-adjusting portion. The rod body I is connected with the length-adjusting portion through an axis pin I, and the rod body II is connected with the length-adjusting portion through an axis pin II. The adjustable pull rod has the advantages that traditional adjustable pull rod structure is changed, and screw rods are matched with slide blocks to adjust length and prevent the pull rod from loosening when the pull rod is used for a long time; and the adjustable pull rod is simple in structure and good in using effect, and parts are easy to produce.
Description
Technical field
The present invention relates to the MACHINERY JOINT field, especially relate to the adjustable drawbar that a kind of length can be regulated as required.
Background technique
Mechanical adjustable draw rod majority commonly used at present is to be divided into two sections, shown in Figure of description 1, has comprised the body of rod 1, locking nut 2 and inner thread sleeve 3, and inner thread sleeve 3 is finished the adjusting of pull bar length by nut 2 matches with falling to the greatest extent.The advantage of this kind pull bar is simple in structure, with low cost, but its locking nut 2 is prone to loosening phenomenon at long-term vibration processes, thereby be difficult to guarantee the length of pull bar, and the meeting appearance rotation relatively after locking nut is loosening of the body of rod 1 on inner thread sleeve 3 both sides, influenced the normal use of pull bar connection device.
Summary of the invention
The objective of the invention is to overcome the shortcoming that exists in the prior art, the adjustable drawbar that locking nut becomes flexible situation can not appear after a kind of length adjustment facility, the long-term use were provided, the technological scheme that adopts is: a kind of adjustable drawbar, comprise body of rod I and body of rod II, it is characterized in that: described adjustable drawbar also comprises the length adjustment part, described body of rod I partly is connected with described length adjustment by the bearing pin I, and described body of rod II partly is connected with described length adjustment by the bearing pin II.
Technological scheme of the present invention also has: the slide block that described length adjustment partly comprises housing, baffle plate, is arranged on the leading screw of described baffle interior, cooperates with threads of lead screw, described body of rod I is connected on the described housing by the bearing pin I, and described body of rod II is connected on the slide block by the bearing pin II.
Technological scheme of the present invention also has: described body of rod I all is connected with miscellaneous equipment by hanging head with body of rod II.
Beneficial effect of the present invention is: the present invention has changed the structure of conventional lengths adjustable draw rod, and the employing leading screw reaches length-adjustable with cooperating of slide block and prevents the long-time tight purpose in back of using.That the present invention has is simple in structure, using effect good, the easy advantage of processing of part.
Figure of description
Accompanying drawing 1 is traditional adjustable drawbar structural representation, and accompanying drawing 2 is structural representations of the present invention, and accompanying drawing 3 is A-A views of accompanying drawing 2, wherein 11 is bodies of rod, the 12nd, and locking nut, the 13rd, inner thread sleeve, the 21st, hanging head, the 22nd, body of rod I, the 23rd, body of rod II, the 24th, the bearing pin I, the 25th, bearing pin II, the 26th, baffle plate, the 27th, housing, the 28th, slide block, the 29th, leading screw.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.The invention discloses a kind of adjustable drawbar, this pull bar comprises body of rod I 22, body of rod II 23 and length adjustment part, and wherein body of rod I 22 partly is connected with length adjustment by bearing pin I 24, and body of rod II 23 partly is connected with length adjustment by bearing pin II 25.Length adjustment partly comprises housing 27, baffle plate 26, is arranged on the leading screw 29 of baffle plate 26 inside, with the slide block 28 of leading screw 29 screw-thread fit, body of rod I 22 is connected on the housing 27 by bearing pin I 24, body of rod II 23 is connected on the slide block 28 by bearing pin II 25.Body of rod I 22 all is connected with miscellaneous equipment by hanging head 21 with body of rod II 23 during installation.
During use, rotational lead screw 29 is realized advancing of slide block 28 or is retreated, and then the relative position between change hanging head 21 and the length adjustment part, reaches the purpose of regulating tie bar length.The rotation of leading screw 29 realizes by rotating spanner.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention also is not limited only to above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement also belong to protection scope of the present invention.
Claims (3)
1. adjustable drawbar, comprise body of rod I and body of rod II, it is characterized in that: described adjustable drawbar also comprises the length adjustment part, and described body of rod I partly is connected with described length adjustment by the bearing pin I, and described body of rod II partly is connected with described length adjustment by the bearing pin II.
2. according to the described adjustable drawbar of claim 1, it is characterized in that: the slide block that described length adjustment partly comprises housing, baffle plate, is arranged on the leading screw of described baffle interior, cooperates with threads of lead screw, described body of rod I is connected on the described housing by the bearing pin I, and described body of rod II is connected on the slide block by the bearing pin II.
3. according to claim 1 or 2 described adjustable drawbars, it is characterized in that: described body of rod I all is connected with miscellaneous equipment by hanging head with body of rod II.
