The lockup device comprises a stop device, a locking device, and an extruding device, wherein, the stop device can lock a front helmet sheet and a center helmet sheet when the helmet extends; the locking device can lock the center helmet sheet and a back helmet sheet; the helmet is folded through the extruding device. The utility model can be automatically locked when extended. When folded, as long as a loosening device is thumbed to forwards push the helmet sheets, the utility model can be conveniently folded.
Description
The utility model relates to a kind of folding helmet.
Though the existing collapsible helmet can fold, its locking device all is arranged on helmet outside.For example a kind of collapsible helmet of 88217603.X utility application proposition during expansion, is locked by being arranged on the helmet outer rectangle mortise lock or hasp, will extract mortise lock when folding or unclamp hasp, and this not only influences outward appearance but also locking action is loaded down with trivial details.
The purpose of this utility model provides a kind of locking device and is arranged in the helmet and the collapsible helmet of folding convenient.
The purpose of this utility model realizes in the following way.A kind of collapsible helmet comprises helmet sheet, connector and locking device, and the internal shoulder of the internal shoulder of last helmet sheet trailing edge and back one helmet sheet leading edge is a watt shape and is connected, and it is characterized in that described locking device comprises:
A. the stop device in being arranged in the helmet sheet, this stop device comprises detent and unclamps handle, the stop head of this detent is subjected to elastic reaction that an additional force that makes progress is arranged, when the helmet launches, stop head embeds the locating hole that is opened in the last helmet sheet, two helmet sheets in before the locking, stop head can overcome elastic force and move downward locating hole under the effect of unclamping handle;
B. be arranged on the locking device in the helmet sheet of back, the positioning head of this locking device slides up and down to be arranged in the hole that is opened on the helmet sheet leading edge position, back and is subjected to elastic reaction that an additional force that makes progress is arranged, when the helmet launches, in the lock hole during positioning head embeds and is opened on the helmet sheet trailing edge, back two helmet sheets in the locking;
C. be installed in the pressurizing unit on the helmet sheet leading edge of back, behind the helmet sheet, this pressurizing unit pushed above-mentioned stop device and unclamps above-mentioned stop head during back helmet sheet was folded.
During the utility model is located at the stop in the locking device, locking and pressurizing unit in respectively, on the helmet sheet of back, and make the stop head of stop device and the positioning head of positioner that an additional force that makes progress be arranged by elastic force.When the helmet launches, under the effect of additional force, the stop head that is installed in the stop device on the helmet sheet embeds in the locating hole of preceding helmet sheet, the locking before, in two helmet sheets, the positioning head of locking device pass the hole that is opened on the helmet sheet leading edge of back embed be opened in hole in the helmet sheet trailing edge, in the locking, the two helmet sheets of back.When folding, the handle that unclamps of pressing locking device makes positioning head deviate from the interior hole of middle helmet sheet trailing edge, postponing the helmet sheet folds into middle helmet sheet, when after the helmet sheet fold in behind the helmet sheet, be installed with pressurizing unit on the helmet sheet leading edge of back run into and push be arranged in positioner on the helmet sheet leading edge, hole before making positioning head deviate to be opened on the helmet sheet trailing edge, the helmet sheet was folded together into preceding helmet sheet during back helmet sheet drove.The utility model is inserted inner helmet with locking device, not only outward appearance is beautiful, and under the effect of elastic force, can utilize positioning head and stop head to carry out locking positioning quickly, when folding, as long as the handle that unclamps of pressing locking device promotes back helmet sheet, just can fold easily, thereby the auto lock of having realized the helmet is located and is folded.
Further specify principle of the present utility model below in conjunction with embodiment.
Brief description
Profile when Fig. 1 is the expansion of the utility model embodiment.
Fig. 2 is the profile after the utility model embodiment shown in Figure 1 folds.
Fig. 3 is that the A of Fig. 1 is to view.
Fig. 4 is that the B of Fig. 1 is to view.
The 1st, preceding helmet sheet, the 2nd, middle helmet sheet, the 3rd, back helmet sheet.Preceding helmet sheet 1 hinder marginal part is an internal shoulder 21, offers a locating hole 14 at the position near internal shoulder 21.The leading edge of middle helmet sheet 2 is provided with outer convex shoulder 22, the leading edge end of the middle helmet sheet 2 of the front side of convex shoulder 22 is provided with the detent 4 that an energy rotates around steady pin 6 outside, be with torsion spring 5 on the steady pin 6, detent 4 has an additional force that clockwise rotates under the effect of torsion spring 5; The outside at the internal shoulder 23 of middle helmet sheet 2 trailing edges offers stop hole 15.Obliquely be installed with the swash plate 11 of an extruding usefulness on the outside of the outer convex shoulder 24 of back helmet sheet 3 leading edges; Convex shoulder 24 inboard one side offer one and stop hole 15 corresponding through holes outside; One end of locating button 8 is installed on the back helmet sheet 3 by screw 13 and holder 12, and the positioning head 9 of locating button 8 other ends is located in the above-mentioned through hole cantilever-shapedly; An end that unclamps handle 7 of being made by iron wire is enclosed between positioning head 9 and the holder 12, and the middle part of unclamping button 9 is set on the holder 12.
When the helmet launched, detent 4 had the additional force of a clockwise under the effect of torsion spring 5, and when the internal shoulder 21 of central helmet sheet 2 outer convex shoulders 22 and preceding helmet sheet was close to, the stop head 17 of detent 4 embedded locating hole 14, two helmet sheets during locking is preceding; When the outer convex shoulder 24 of same back helmet sheet 3 is close to the internal shoulder 23 of middle helmet sheet 2, the hole 15 during the positioning head 9 of locating button 8 embeds under the elastic force of the cantilever of locating button 8 on the helmet sheet 2, back two helmet sheets in the locking.
When folding, pressing unclamps handle 7, unclamps handle 7 and rotates counterclockwise around holder 12, and its other end is provoked the positioning head 9 of locating button 8, makes positioning head 9 throw off hole 15, postpones helmet 3 it is folded into middle helmet sheet 2; When the swash plate 11 on the leading edge position of the back helmet sheet of folding 3 is run into detent 4, swash plate 11 extruding detents 4, the power that makes detent 4 overcome torsion spring 5 rotates counterclockwise, stop head 17 is deviate from hole 14, under the promotion of back helmet sheet 3, back helmet sheet 3 by swash plate 11 squeeze push away detent 4 and drive in helmet sheet 2 fold together before in the helmet sheet 1.
Principle of the present utility model can also realize by other the whole bag of tricks.For example the structure of detent 4 and swash plate 11 and combination can realize with the mode of voussoir extruding; And the locating button 8 and the combination of unclamping handle 9 also can be unclamped positioning head by the voussoir extruding, extract behind the voussoir elastic force positioning head mode that embeds that resets is realized.Therefore the locking device of similar voussoir etc. all can be realized by the distortion to detent of the present utility model and locating button and pressurizing unit.
