Abstract
The utility model discloses an adjustable screwed telescopic positioning stay bar which is composed of a right and a left struts which are in abutting joint through right-hand screw threads and left-hand screw threads, and the lengths of the two struts are adjusted by a screwed shank at the joint point. The adjustable screwed telescopic positioning strut can meet the requirements of different lengths by using the length adjustability of the right-hand and left-hand screw threads struts capable of flexing towards two sides at the both ends of the screwed shank, and can be used in a closed place. In addition, a positioning block can be made into a separate type and can be replaced, so that the universality of the positioning strut is stronger. A tension function is obtained with the replaceable positioning block and the telescopic movement of the strut, so that the universality and the flexibility of the positioning strut are further improved. The application range of the positioning strut is widened through the screwed adjustability, the number of craft equipment is reduced, and the product manufacture cost is saved.
Description
Technical field
The utility model relates to a kind of positioner that is mainly used in spacing in frame, the beam assembling.
Background technology
At present, at home, outer massive parallel or symmetrical flat part, apart from the not high assembling of precision prescribed, widely apply positioner in frame or case bay positioning supports, usually adopt two ends to be shaped on the ring flange that varies in size, the changeless stock formula of length dimension positioning supporting rod.The weak point of this positioning supporting rod is a fixed size, and length is of a great variety, and is diversified in specifications, and versatility is poor, uses poor for applicability at the working space of not opening wide.And consumption is big, and is idle many.
Summary of the invention:
The purpose of this utility model provides a kind of and can reduce usage quantity at the weak point that above-mentioned prior art exists, and saves manufacturing cost, uses length adjustable flexibly, the adjustable spiral of the highly versatile positioning supporting rod that stretches.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of adjustable spiral positioning supporting rod that stretches, comprise, two ends are fixedly connected with the strut of locating piece, it is characterized in that, strut is made up of the whisker boom of left and right hand thread butt joint, and regulates its length by the spiral handle at tie point place.
The utility model has following beneficial effect than prior art.
The left and right hand thread strut that the utility model utilizes the spiral handle two ends is to the flexible adjustable length in both sides, makes backstay promptly adapt to the requirement of different length, again can be in the applications of sealing.In addition, locating piece 1,5 is made detachable, also replaceable different locating piece, thus make the versatility of positioning supporting rod stronger.Also can increase the function of tension with the contractile motion of interchangeable locating piece and strut, can further improve the versatility and the flexibility of positioning supporting rod.Adjustable by spiral, not only enlarged the scope of application of positioning supporting rod, also reduced the frock usage quantity simultaneously, saved cost of goods manufactured.
Description of drawings
Further specify the utility model below in conjunction with drawings and Examples, but therefore the utility model is not limited among the described scope of embodiments.
Fig. 1 is the vertical section structural map of first embodiment of the utility model.
Fig. 2 is the vertical section of two embodiment of the utility model structural map that fractures.
Fig. 3 is the vertical part section of three embodiment of the utility model structural map that fractures.
The specific embodiment:
Among Fig. 1, two ends are fixedly connected with locating piece 1 left strut 2 and right strut 4 connects into the positioning supporting rod of regulating its length by spiral handle 3.Strut is made up of the whisker boom of left and right hand thread butt joint, and regulates its length by the spiral handle at tie point place.Left side strut 2 adopts left hand thread engagement with spiral handle 3 left ends, and right strut 4 adopts right-handed thread to cooperate with spiral handle 3 right-hand members.The strut at two ends is stretched out simultaneously together with locating piece or regain, make the positioning supporting rod adjustable length.Locating piece 1,5 difference interference fits are in the two ends of whisker boom 2,4.With locating piece and the enhancing versatility that is convenient for changing different specifications.As long as, can satisfy the instructions for use of different length excursion by changing " A " value of positioning supporting rod length.
In the embodiment shown in Figure 2, spiral handle 3 can change matched in clearance into whisker boom 2,4.The pin hole 7 that spiral handle 3 and whisker boom 2,4 junctions are shaped on the different size section is equipped with fastening screw 6 on it.So just can accurately locate by fastening screw 6.
In the embodiment shown in fig. 3, the connecting portion at spiral handle 3 two ends is shaped on the fastening screw of radial location, and the steel ball 11 that is compressed by spring 10 is housed in the fastening screw, whisker boom 2,4 connecting portions circumferentially be shaped on different size section annular groove.Steel ball 11 is pressed in the groove through spring 10 by trip bolt, thereby accurately locatees the use length of two ends whisker boom 2,4.
Claims (5)
1. the flexible positioning supporting rod of adjustable spiral comprises that two ends are fixedly connected with the strut of locating piece, it is characterized in that strut is made up of the whisker boom of left and right hand thread butt joint, and regulates its length by the spiral handle at tie point place.
2. the adjustable spiral according to claim 1 positioning supporting rod that stretches is characterized in that, left strut 2 and spiral handle (3) left end are by left hand thread engagement, and right strut (4) is cooperated by right-handed thread with spiral handle (3) right-hand member.
3. the adjustable spiral according to claim 1 and 2 positioning supporting rod that stretches is characterized in that, locating piece (1,5) respectively interference fits in the two ends of whisker boom (2,4).
