Abstract
The invention relates to a method for assembling a telescopic screw, which comprises the following steps: providing an annular base body, and placing an annular gasket at the upper end of the annular base body; providing a screw, a telescopic spring and a sleeve, wherein the screw is provided with a screw head which is provided with a screw rod section and a screw thread section by extending downwards sequentially, and the upper end of the sleeve is contracted with a through hole; making the screw thread section run through the telescopic spring and the through hole so that two ends of the telescopic spring are supported against the screw head and the sleeve respectively; and making diagonal threads of the screw thread section screwed in with gaps and run through the annular gasket so that the annular gasket is sleeved on the screw thread section and is limited between the downside of the through hole and the upper end of the screw thread section. The method has the effects of keeping a smaller inner diameter for the annular gasket so that the annular gasket is sleeved on the screw rod section of the screw more tightly, increasing the strength and the reliability for assembling the screw and the sleeve, reducing the volume of the annular gasket to further reduce the integral volume of the sleeve and the screw, and using a simpler assembling tool to reduce the manufacturing cost.
Description
Technical field
The present invention relates to a kind of assembling method of telescopic screw, the thread section that particularly relates to a kind of screw is screwed into and runs through ring washer, increase the intensity and the reliability of the assembling of screw and sleeve, dwindle the telescopic screw overall volume, and use simple assembling tool can reduce the assembling method of the telescopic screw of manufacture cost.
Background technique
See also Fig. 1, shown in Figure 2, Fig. 1 is for having the STRUCTURE DECOMPOSITION schematic perspective view of known telescopic screw now, and Fig. 2 is for having the structure cross-sectional schematic of known telescopic screw now.Existing known telescopic screw 1 comprises a screw 11, a coil tension spring 12, a sleeve 13 and a ring washer 14.Wherein, this screw 11 has a screw terminal 111, and this screw terminal 111 extension in regular turn downwards is provided with a spiro rod section 112 and a thread section 113; Contracting in the upper end of this sleeve 13 is provided with a perforation 131, and the outside is provided with an outer contact edge 132.After telescopic screw 1 assembling, this ring washer 14 be sheathed on spiro rod section 112 and be limited in the below of perforation 131 and the upper end of thread section 113 between, ring washer 14 makes sleeve 13 activity set be loaded on screw 11, and two ends of coil tension spring 12 are then distinguished the outer contact edge 132 of contact screw terminal 111 and sleeve 13.Above-mentioned telescopic screw 1 is widely used in the assembling that plate combines to plate.
See also Fig. 3 to shown in Figure 6, Fig. 3 is for having the schematic representation one of known telescopic screw assembling method now, and Fig. 4 is a schematic representation two, and Fig. 5 is a schematic representation three, and Fig. 6 is the part-structure enlarged diagram of Fig. 5.Existing known telescopic screw assembling method, provide an annular base body 17, be provided with an annular cutter 18 in this annular base body 17, the gasket materials 16 that is provided with at least one perforation 161 is placed in annular base body 17 upper ends, sleeve 15 is arranged at gasket materials 16 tops, screw 11 is placed in the sleeve 15, the two ends difference contact screw terminal 111 of coil tension spring 12 and the interior contact edge 153 of sleeve 15.In when assembling, the screw terminal 111 that presses down screw 11 with press tool 2 once makes the thread section 112 of screw 11 run through the perforation 161 of gasket materials 16; Then, as shown in Figure 5, be arranged at annular cutters 18 in the annular base body 17 and move up and cut out the spiro rod section 112 that a ring washer 14 is sheathed on screw 11, and in being limited between contact edge 153 belows and thread section 113 upper ends, make sleeve 15 activity set be loaded on screw 11 by ring washer 14.Yet, existing known telescopic screw assembling method, be perforation 161 inner edges that run through gasket materials 16 with the thread section 112 of screw 11, its ring washer 14 inner edges that annular cutter 18 is cut out are subjected to the wearing and tearing of thread section 113 and enlarged inner diameter, the support force of ring washer 14 inner edge contact thread sections 113 upper ends is died down, when making sleeve 15 activity set be loaded on screw 11 at last, sleeve 15 gets loose from the thread section 113 of screw 11 easily.In addition, the internal diameter that existing known telescopic screw assembling method amplifies because of wearing and tearing for compensation ring washer 14 inner edges, so ring washer 14 needs up-sizing in advance, it also need amplify the overall dimensions of telescopic screw 1 and can't downsizing.Moreover existing known telescopic screw assembling method need utilize the assembling tool of labyrinth, following press tool 2, annular base body 17 and annular cutter 18...... etc., thus increased manufacture cost.
This shows that the assembling method of above-mentioned existing telescopic screw obviously still has inconvenience and defective, and demands urgently further being improved in method and use.For solving the problem of above-mentioned existence, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and general assembling method does not have appropriate method to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.Therefore how to found a kind of assembling method of new telescopic screw, so that ring washer can be possessed less internal diameter, more closely to be sheathed on the spiro rod section of screw, increase the intensity and the reliability of the assembling of screw and sleeve, and can make the ring washer reduced volume, and then dwindle the telescopic screw overall volume, and can use better simply assembling tool to reduce manufacture cost, real one of the current important research and development problem that belongs to, also becoming the current industry utmost point needs improved target.
Because the defective that the assembling method of above-mentioned existing telescopic screw exists, the inventor is based on being engaged in this type of product specification manufacturing abundant for many years practical experience and professional knowledge thereof, and the utilization of cooperation scientific principle, actively studied innovation, in the hope of founding a kind of assembling method of new telescopic screw, can improve the assembling method of general existing telescopic screw, make it have more practicability.Through constantly research, design, and after studying repeatedly and improving, create the present invention who has practical value finally.
