Abstract
The utility model provides an expansion rod with simple structure. When an inside rod of the expansion rod is picked out from an outside rod, convex part and springs can not fall off, and the treatment is easy to carry out. A telescoping rod 1 is designed into a slidable inside rod 3 which can be inserted into an outside rod 2; the inside rod 3 is provided with mounting holes 8; a convex part 9 is installed by that the springs 10 are pressed on the convex directions; the mounting holes 8 are in a circular shape, and a blocking part with small diameter is formed at the front ends of the mounting holes; the convex part 9 is in a cylindrical shape, the front end of which is in a hemisphere shape, a fall off preventing part with big diameter is formed at the back end, and inserting holes are formed at the back end part in the fall off preventing part. Further more, the convex part 9 is inserted into the back ends of the mounting holes 8, and a part of the springs 10 is inserted into the inserting holes of the convex part 9 and connected in riveting with the back ends of the mounting holes 8 to prevent the falling off. 3 positions on the outside rod 2 are provided with inserting holes 7 used for being inserted by the convex part 9.
Description
Technical field
The utility model relates to a kind of length-adjustable expansion link that is used to hang utensil etc.
Background technology
Opening disclosed among the flat 2-55100 the spy is not telescoping mechanism, but the spring loaded clinching of will being pressed is inserted in the circular hole of protruding axle and should protruding axle insertion slit in.In addition, real open among the clear 54-14727 disclosed be framework is located in the pipe and dowel is installed therein reaches to its spring that pressurizes.
Summary of the invention
In the above-mentioned known example the former just will be by the pressing spring apical grafting at the slit inner face, if the problem that will produce clinching and come off from protruding axle by pressing spring is stretched out in clinching from slit.In addition, the latter of known example then is, though will be sold inside the country and the spring of its pressurization is stretched out from pipe, also can not come off, and can produce complex structure and can't the low-cost problem of making.
The utility model is in order to address the above problem, a kind of expansion link is provided, side lever was to adjust length in it inserted on the tubulose outboard beam slidably, side lever is provided with installing hole within it, will be on projected direction be mounted to and make its turnover by spring loaded protuberance, and the many places on outboard beam are provided with the jack for this protuberance intercalation, installing hole with vertically vertical direction on break-through, and be provided with the stop section of minor diameter at leading section, protuberance is roughly cylindric and is provided with large diameter removal stop section at the rear portion, and be provided with patchhole and the part of spring is inserted from rearward end, the protuberance that is inserted with spring is inserted from the rear end of installing hole, make removal stop section and stop section apical grafting mutually, and make the rearward end anti-avulsion of installing hole, on interior side lever, protuberance is mounted for some outstanding state of front end from installing hole.
The effect of invention:
Because protuberance and make the spring of its pressurized be installed in interior side lever, even therefore interior side lever is taken out from outboard beam, protuberance and spring can not come off yet.
Description of drawings
Fig. 1 is whole front view.
Fig. 2 is the amplification profile of the A-A line of Fig. 1 major part.
Fig. 3 is the amplification decomposing section of major part.
Fig. 4 is the part abridged front view of user mode.
The specific embodiment
Installing hole 8 is located on the interior side lever 3, and protuberance 9 is installed wherein.Installing hole 8 is circular, and its leading section forms the slightly little stop section 8a of diameter, and protuberance 9 is cylindric, and its front end is outstanding to be hemispherical, and rearward end forms the big slightly removal stop section 9a of diameter, and forms patchhole 9b from rearward end therein.And, protuberance 9 is inserted from the rear end of installing hole 8, and make the part of trapezoidal spring 10 insert among the patchhole 9b of protuberance 9 and with the rear end riveted joint of installing hole 8 so that the rearward end of spring 10 can not be deviate from.Therefore, interior side lever 3 is even without inserting in the outboard beam 2, and protuberance 9 and spring 10 can not come off from interior side lever 3 yet.In addition, be pressed into lid etc., and it fixed in case anti-avulsion goes out also can by welding in the rear end of installing hole 8.Protuberance 9 is subjected to spring pushing on projected direction, and the stop section 8a of removal stop section 9a and installing hole 8 is apical grafting mutually, and is fixed in case anti-avulsion goes out with the outstanding state of the part of its leading section.And 3 places on outboard beam 2 are provided with jack 7 ... 7.
While pushing outstanding protuberance 9 interior side lever 3 is inserted outboard beam 2 and it is slided, when protuberance 9 arrives the position of jacks 7, make the outstanding and intercalations of protuberance 9 in patchhole 7 by the power of spring 10.When adjusting length, be pressed into from jack 7 outstanding protuberances 9 so that interior side lever 3 slides and is intercalated in other jacks gets final product.
This expansion link 1 inserts the buckling parts 6 of front end and to be installed on the support portion 11 of ceiling from the below, and makes it rotatable supported, is used for hanging at hang part 4 article such as utensils with this.
The effect of invention:
If above-mentioned the utility model, because protuberance and the spring fitting that makes its pressurized are in interior On the side lever, even therefore interior side lever is taken out from outboard beam, protuberance and spring can not sent out yet Therefore living coming off obtain the easy to handle effect.
And, because both can be with protuberance and spring fitting on interior side lever with simple structure, Therefore can reach the effect of low cost fabrication.
