Embodiment
For the purpose, technological scheme and the advantage that make the utility model embodiment is clearer,, the utility model embodiment is done explanation in further detail below in conjunction with embodiment and accompanying drawing.At this, illustrative examples of the present utility model and explanation are used to explain the utility model, but not as to qualification of the present utility model.
Referring to Fig. 1 and Fig. 2, this screw 10 that do not come off comprises: screw rod 11, sleeve 12, spring 13 and rubber ring 14, wherein screw 11 comprises first end and threaded the second end is set, on first end, be arranged with rubber ring 14, and on the second end, be arranged with sleeve 12, on spring 13 is arranged in the containing space in the second end of screw rod 11, and an end of this spring 13 is connected with sleeve 12, and the other end is connected with screw rod 11.
In the present embodiment, this screw rod 11 can be selected carbon steel material for use, and is shaped as cylindrical structure, can on the first end of this screw rod 11 and the second end 45 degree chamferings be set for the ease of installing.And in order to make this screw 10 that do not come off have guide function, can select the length of screw rod 11, for example choose the length of screw rod 11 according to the total thickness of link according to actual conditions.Above-mentioned rubber ring 14 is set on the first end in the mode that can move freely, certainly also this rubber ring 14 can be fixed on the first end, for example can one groove ring be set at first end, the degree of depth of this groove ring can be provided with according to actual conditions, rubber ring 14 is arranged in this groove ring then, the damping that utilizes rubber ring 14 to be compressed to be produced realizes the guiding of the 3rd link (see figure 4) is connected, make the 3rd link perpendicular to screw rod 11 axially on can not slide by non-resistance.The structural representation of this rubber ring 14 can shown in the figure for the internal diameter of this rubber ring 14 be referring to Fig. 3
4.0mm external diameter is
7.6mm situation.Do not limit the means of fixation of this rubber ring 14 on first end in the present embodiment, and the number of rubber ring 14.
This sleeve 12 and spring 13 can be selected aluminium sleeve and the spiral spring in the existing screw that do not come off for use, and on this sleeve 12 caulking part are set, by cooperating and this sleeve 12 can be riveted on second link with counterbore on the second link (see figure 4).Certainly sleeve 12 also can be connected with second link by other modes.Screw thread on this second end can be selected internal thread or outside thread according to actual conditions, by screw 10 (see figure 4) that is threaded with first link that this can not come off of the screw thread on the second end.
Referring to Fig. 4, assembling schematic representation for three links among the embodiment of the present utility model, these three links are respectively first link 21 that is provided with tapped through hole, be provided with second link 22 of counterbore and the 3rd porose link 23 is set, at first, cooperate with counterbore on second link 22 by the caulking part on the sleeve 12, sleeve 12 is riveted on second link 22, by the screw thread on the second end this screw 10 that do not come off is fixed on first link 21 then, realized being connected of two links (first link 21 and second link 22) this moment, at last the 3rd link 23 with holes has been inserted to the screw 10 that do not come off.
In the present embodiment, the surface of the screw rod 11 between sleeve 12 and the rubber ring 14 is provided with many projections with screw rod 11 parallel to an axiss, thereby can this screw 10 that do not come off be screwed on first link 21 by manual mode.Perhaps, also cross recess or straight groove can be set on the end face of first end, the user also can operate this screw 10 that do not come off by cruciform screw driver or in-line screwdriver like this, thereby can be screwed into line operate by hand, also can operate, be convenient to user's operation by screwdriver.Referring to Fig. 5, for to be provided with cross recess 41 on the end face 40 of first end, the groove depth of this cross recess 41 can be provided with according to actual conditions shown in the figure.
As shown from the above technical solution,, make this screw that do not come off to realize the connection of three above component, and install simple, quick by increasing the guide function of screw rod.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
