Abstract
The utility model relates to a linking device for a support knuckle, comprises that one head of a knuckle extends convexly a bushing and a lever arm is sleeved and fixed in the bushing of the knuckle, and is characterized in that at least one open slot is cut on the peripheric cycle of the lever arm, the inner part of the bushing of the knuckle that is according to the open slot is also provided with at least one convex rib, by means of which the lever arm is sleeved and fixed in the bushing of the knuckle, the convex rib is inserted in the open slot, thus without utilizing any viscose, the assembling can be finished easily and the device also firm and beautiful.
Description
Technical field
The utility model relates to the combination apparatus in a kind of support and joint.
Background technique
The support joint was to give the pivot knot by two joints of intersecting between the lever arm of tying, and the flexible effect of adjusting angle, camber was provided in the past.Be the lever arm 1 in support joint in the past and the structure in joint 2 as shown in Figure 1, 2, its lever arm 1 is the hollow tube of tubulose, and joint 2 is at one end to convex with a sleeve pipe 201, its group mode, just in the sleeve pipe 201 in joint 2, be coated with an amount of viscose 202, then, lever arm 1 one ends directly be inserted in the sleeve pipe 201 in joint 2, after viscose 202 dries up, promptly finish the assembling of joint 2 and lever arm 1.
And utilize aforementioned tube to connect cemented mode, though can make lever arm 1 and joint 2 reach the purpose that fixes as one, the assembling mode in right its lever arm 1 and joint 2, but when reality is used, still there is following shortcoming and needs to be resolved hurrily: because lever arm 1 utilized viscose 202 cemented with 2 in joint in the past, there is no other auxiliary spacing structure, when the angle of lever arm 1 is adjusted in operation, pull lever arm 1 as the adjustment angle of secundum legem not, will be because of the gel of viscose 202, cause the gummed place because of improper reverse to pivot get loose, therefore and can't be produce slit 203, and cause article that lever arm 1 end linked at tilt fixing, use under the camber, especially in the middle of working, press for the adjustment special angle, (especially link and use on the machining machine and tool of meeting vibrations) during camber, the puzzlement on easier generation is used, therefore, the lever arm 1 in described in the past support joint and joint 2 utilize viscose 202 solid mode, not only firm inadequately, its must row again coat viscose 202 solid trouble, assembling inconvenience more seems.At above-mentioned support in the past joint Caused by Lever Arm 1 and the not firm and solid shortcoming in joint 2, other have industry sleeve pipe winding place in described lever arm 1 and joint 2 utilize a bolt 204 by outside give packing (shown in the imaginary line of Fig. 2) toward in, make its borrow viscose 202 solid outside, also increase the step of one locking, improving firm and solid degree, but described mode, and its bolt 204 is exposed to lever arm 1 outside, then seem not attractive in appearance, and the outside impression of destroying lever arm 1 is arranged.
Summary of the invention
The purpose of this utility model is in providing a kind of simple and convenient assembly quick and firm support joint combination apparatus attractive in appearance again.
Support of the present utility model joint combination apparatus, be included in a sleeve pipe and a lever arm that overlaps in the sleeve pipe that is fixed in described joint that a joint one end protrudes out, be characterized in: offer an opening slot on the chow ring of described lever arm at least, and the inside pipe casing in described joint is provided with a fin at least with respect to the opening slot place.
Be fixed in by the lever arm cover in the sleeve pipe in joint, its fin is embedded in the opening slot, need not utilize viscose cemented again, can simple and easyly finish assembling.
Below by most preferred embodiment and accompanying drawing support of the present utility model joint combination apparatus is elaborated, in the accompanying drawing:
Description of drawings
Figure 1 shows that the schematic representation in support joint in the past;
Figure 2 shows that the lever arm in support joint and the assembled sectional view in joint in the past;
Figure 3 shows that the three-dimensional exploded view of the utility model one preferred embodiment;
Figure 4 shows that the generalized section of the utility model one preferred embodiment fit front and back;
Shown in Figure 5 is combination section for the utility model one preferred embodiment.
Embodiment
Shown in Fig. 3,4, " the support joint combination apparatus " of the utility model one preferred embodiment, be to have protruded out a sleeve pipe 11 at a joint 10 1 ends, one lever arm 20 then cover is fixed in the sleeve pipe 11 in joint 10, be characterized in: 10 its sleeve pipe 11 inside, described joint are provided with a wedge shape fin 111 at least, present embodiment is to be provided with two wedge shape fins 111, and chow ring is the one-body molded interior ring edge 112 that has in it, described sleeve pipe 11 inner bores are slightly less than sleeve pipe 11 outside bores, make the tapering (being commonly called as drafting angle) that forms about 2 degree.
Described lever arm 20 is to be a hollow tube, and its each end offers an opening slot 21 at least.During assembling, as Fig. 3,4, earlier described lever arm 20 is aligned the bore of joint 10 sleeve pipes 11, with suitable strength with lever arm 20 transplantings in the sleeve pipe 11 in joint 10, at this moment, because of the width of the opening slot 21 of lever arm 20 only suitable with the terminal width of wedge shape fin 111, so along with the grafting of lever arm 20 with sleeve pipe 11,111 of the wedge shape fins of described sleeve pipe 11 inside strut packing opening slot 21, and make wedge shape fin 111 and opening slot 21 fastening mutually, secondly, at wedge shape fin 111 stretching opening slots 21 simultaneously, the meat of lever arm 20 thick 22 is being subject to and 112 clampings of interior ring edge relation, and 20 of described lever arms firmly are combined as a whole with the sleeve pipe 11 in joint 10.
The utility model has following listed advantage and effect in fact by above-mentioned structure:
The utility model is borrowed in the sleeve pipe 11 in described joint 10 and is provided with wedge shape fin 111, when making described lever arm 20 with joint 10 assemblings, not only can borrow the opening slot 21 of lever arm 20 urgent fixing with wedge shape fin 111, simultaneously, the interior ring edge of establishing in the described sleeve pipe 11 112 also can appropriate clamping lever arm 20 meat thick 22, make lever arm 20 at the wedge shape fin 111 that is subjected to sleeve pipe 11 fixedly the time, also can be subjected to interior ring edge 112 to form the effect of dual clamping, so, described joint 10 and lever arm 20 assemblings, not only easy need not for another example in the past must be cemented with viscose fast, do not have the puzzlement of coming unstuck and pivoting, and can not cause needs to adjust the steady job angle, difficulty in the time of on the camber, simultaneously, above-mentioned affixed mode of the present utility model is solid except not utilizing the bolt spiral shell, outside viscose, can not destroy lever arm 20 aesthetic appearances yet.
