Detailed description of the invention
In order to the technical solution of the utility model is explained further, it is described in detail below in conjunction with accompanying drawing.
Referring to figs. 1 through Fig. 8, a kind of band cap spring head, including pull head body 10, it is configured with pulling-on piece 20 and cap 30 that axle portion 21 is installed.Pull head body 10 includes upper flange 101, lower wing plate 102 and the guide pillar 103 being connected between upper flange 101 and lower wing plate 102, and upper flange 101, lower wing plate 102 and guide pillar 103 surround to guide the guiding channel of slide fastener (not shown) jointly. Upper flange 101 is provided with the first pulling-on piece mounting post 107 and the second pulling-on piece mounting post 108, the installation axle portion 21 of pulling-on piece 20 is pivotally disposed between the first pulling-on piece mounting post 107 and the second pulling-on piece mounting post 108, fixing post 105 and rear fixing post 106 before being additionally provided with on upper flange 101, cap 30 is fixed by front fixing post 105 and rear fixing post 106. Upper flange 101 is provided with pawl hole 109 and accepting groove 110, also include plate spring component 40, first end of plate spring component 40 has horse hook portion 41, second end relative with the first end is configured in accepting groove 110, by the elasticity of plate spring component 40, when pulling-on piece 20 is horizontal, horse hook portion 41 snaps between the sprocket of slide fastener, thus playing the effect of braking, it is to avoid pull head body 10 is from line slip. The longitudinal section installing axle portion 21 of pulling-on piece 20 is odd-shaped cross section, in order to receive installation axle portion 21 better, upper flange 101 offers deep gouge 104, axle portion 21 part is installed and is accommodated in deep gouge 104, the process of vertical state is turned to from level at pulling-on piece 20, by this installation axle portion 21, plate spring component 40 is lifted gradually, so that horse hook portion 41 is lifted between the sprocket of slide fastener, it is achieved the unblock of slide fastener. Above-mentioned structure, existing introduction, is no longer described in detail here in the prior art.
In this utility model, described accepting groove 110 is through to the lower surface of described lower wing plate 102 from the upper surface of described upper flange 101, and in an embodiment, storage tank 110 passes from top to down from guide pillar 103. The cell wall of accepting groove 110 has the guide portion 111 being obliquely installed, and is provided with limiting section in the lower end of guide portion 111, and described second end is provided with the snap arm 44 coordinated with this limiting section. When assembling, snap arm 44 moves down through the guiding of this guide portion 111, and makes snap arm 44 card lean against on limiting section, thus realizing the fixing of plate spring component 40 second end, so, it is not necessary to carry out spacing setting up the riveting parts the second end to plate spring component 40.
With pull head body 10, one end of guide pillar 103 is set for front end, other end is rear end, as a kind of optimal way of the present utility model, described guide portion 111 includes the first limited block 1111 and the second limited block 1112, described first limited block 1111 and all downward-sloping settings from pull head body 10 rear end to front end of described second limited block 1112, both the first limited block 1111 and the second limited block 1112 be arranged in parallel. Limit channels 112 is formed between first limited block 1111 and the second limited block 1112, described second end of described plate spring component 40 is accommodated in this limit channels 112, described snap arm 44 includes the first snap arm 441 and the second snap arm 442, the lower surface 11111 of the first limited block and the lower surface 11112 of the second limited block form described limiting section, and the first snap arm 441 and the second snap arm 442 card lean against described limiting section. In this utility model, from rear end to front end, described plate spring component 40 includes described horse hook portion 41, cover portion 42, hook part 43 and forms the described snap arm 44 at hook part 43 end, and described horse hook portion 41, cover portion 42, hook part 43 and described snap arm 44 are one-body molded.
Adopt said structure, when assembling, the installation axle portion 21 of pulling-on piece 20 is placed between the first pulling-on piece mounting post 107 and the second pulling-on piece mounting post 108, the fixing of pulling-on piece is realized by riveting the first pulling-on piece mounting post 107 and the second pulling-on piece mounting post 108, afterwards plate spring component 40 is placed in installation axle portion 21, and make horse hook portion 41 pass from pawl hole 109, hook part 43 is resisted against on the first limited block 1111 and the second limited block 1112, by plate spring component 40 is applied downward active force, the first snap arm 441 and the second snap arm 442 that make hook part 43 end move down along the first limited block 1111 and the second limited block 1112, in the process that the first snap arm 441 and the second snap arm 442 move down, the hook part 43 of plate spring component 40 deforms upon and is flared out, when the first snap arm 441 and the second snap arm 442 move the lower end of the lower end of the first limited block 1111 and the second limited block 1112 respectively, plate spring component 40 is recovered deformation and is inwardly bounced back, hook part 43 falls in limit channels 112, when first snap arm 441 and the second snap arm 442 block the lower surface 11112 of lower surface 11111 and the second limited block leaning against the first limited block respectively simultaneously, afterwards cap 30 is covered in the relevant position of upper flange 101, and before cap 20 being fixed on by riveting cap 20 fixing post 105 and after fix on 106.
As a kind of optimal way of the present utility model, the hole portion 31 that the described installation axle portion 21 for described pulling-on piece 20 that all offers on the left and right sidewall of described cap 30 interts, the first side wall 32 that hole portion 31 is arranged by the front end of corresponding described pull head body 10, the second sidewall 33 that the rear end of corresponding described pull head body 10 is arranged and be arranged on the roof 34 of the first side wall 32 and the second sidewall 33 and surround, the first side wall 32 is fixed between post 105 and described first pulling-on piece mounting post 107 before described, second sidewall 33 is fixed between post 106 and described second pulling-on piece mounting post 108 after described. adopt this structure, the hole portion of cap of the prior art is expanded toward the fore-and-aft direction of pull head body 10, surface treatment is carried out at follow-up pull head, during as electroplated, plating solution can flow fully inside and outside cap 30 so that the parts in cap 30 can form homogeneous coating, improve the corrosion resistance of whole pull head, simultaneously after plating when being carried out, plating solution is easier to flow out by this hole portion 31, it is to avoid plating solution remains in and causes the corrosion of corresponding component in cap 30 in cap 30.
Product form of the present utility model is not limited to this case diagram and embodiment, and it is carried out the suitably change of similar thinking or modifies by anyone, all should be regarded as without departing from patent category of the present utility model.
