Description

Fastener for leather suitcases

The utility model is about a kind of leather trunk closure apparatus, refers in particular to the structure comparatively closely that covers of a kind of case lid and casing.

Covering of leather trunk commonly used, it is constructed roughly as shown in Figure 1, and it comprises that one is located at the latch hook 11 on the case lid 1, and the inboard, bottom of latch hook 11 has a groove 12; And a jam plate 21 that is located at the lockset 20 in the casing 2, an end of jam plate 21 is articulated on the lockset 20, and other end inboard then has two locking key 22(to be fit to left and right two usefulness to assembling); When desiring to cover, earlier case lid 1 is pressed down (this moment, lockset was unlocking condition) in the lockset 20 that is pressed into casing, press down jam plate 21 again its locking key 22 is inserted in the groove 12 of latch hook, as shown in Figure 4, to reach the purpose that covers leather trunk.

Above-mentioned leather trunk closure apparatus commonly used obviously is difficult to reach desirable practical effect in the use because of having following defective, and the necessity that haves much room for improvement:

Behind fastening, still have suitable gap (as shown in Figure 4) between locking key 22 and the groove 12; In other words, even case lid 1 also still has sizable gap with casing 2 after covering, and loosening phenomenon is arranged when causing leather trunk to lift.

For solving this problem, common people may directly consider groove 12 dwindled or with locking key 22 enlarged in thickness, yet this has tolerance to exist once the assembling itself that designs because of part, thus occur causing locking key 22 can't buckle into the dead angle of groove 12 on the contrary, obviously inapplicable.

And the utility model creator design originally is to imagine groove 12 is made the shape that an inboard has an inclined-plane 121, and the inboard of locking key 22 also forms the inclined-plane 221 of a downward convergent, as shown in Figure 5, when it can make locking key 22 in more going deep into groove 12 by the cooperation on two inclined-planes 121,221, more can closely fasten; So thus, because of locking key 22 all is to utilize the moulding of zinc material with latch hook 10, the smoothness of itself is not good, therefore very easily form the phenomenon that locking key 22 and groove 12 are killed, and when causing desire to be unpacked, locking key 22 is deviate from groove 12 and is very required great effort, even can produce the problem appearance of mould turnover because of overexerting.If on locking key 22 or groove 12, be coated with lubricating oil (being commonly called as butter), though can lower above-mentioned phenomenon of killing, can make the clothing in the leather trunk suffer the pollution of oil stain, then more be not worth it; Therefore, this obviously feasible design of also non-genus of design.

According to above-mentioned many disadvantages, and continuous design innovation, through progressively improvement, the utility model creator is initiated out new structure of the present utility model finally then.

Main purpose of the present utility model provides a kind of tight and unlikely leather trunk closure apparatus of killing that fastens, and it can improve the defective that said structure exists fully.

The utility model provides a kind of leather trunk closure apparatus, it comprises that one is located at the latch hook on the case lid, its bottom has a groove, and one be located at the jam plate of locking in the casing, and the one end has locking key, it is characterized in that being equiped with in the latch hook groove rotor, with and groove between have a spacing, the locking key medial surface then has the inclined-plane of a downward convergent, it makes locking key be buckled into by this spacing, and can reach the effect of tight fastening with latch hook, make covering of leather trunk case lid and casing more tight; Rotor can be a roller; The inclined-plane of locking key inboard is being preferable less than 45 °.

Now by enumerating a preferred embodiment and cooperating relevant accompanying drawing to describe structure of the present utility model, characteristics in detail.Wherein,

Figure 1 shows that the schematic diagram when leather trunk commonly used is opened;

Figure 2 shows that the stereogram of latch hook in the leather trunk closure apparatus commonly used;

Figure 3 shows that the front view of jam plate in the leather trunk closure apparatus commonly used;

Figure 4 shows that the schematic diagram when locking key is with the latch hook fastening in the leather trunk closure apparatus commonly used;

Figure 5 shows that the fastening schematic diagram of the utility model creator initial design;

Figure 6 shows that the three-dimensional exploded view of the utility model embodiment;

Figure 7 shows that the cross-sectional schematic when the utility model embodiment fastens;

Figure 8 shows that the front elevation of locking key among the utility model embodiment;

Figure 9 shows that the schematic diagram of analysing and observe along A-A among Fig. 7.

To shown in Figure 9, the structure that structure of the present utility model is most of with commonly used is identical, also includes members such as latch hook 11, groove 12, jam plate 21, locking key 22 as Fig. 6; Different is, groove 12 is opened in the bottom of latch hook 11, and axle (dress) is provided with a rotor 13 in it, and rotor 13 can be a roller, and it can do forward and reverse rotation arbitrarily, and makes and be formed with a spacing 14 between roller 13 and the groove 12; The inboard of locking key 22 then forms the inclined-plane 23 of a downward convergent, and the gradient on this inclined-plane 23 is preferable to be no more than 45 °.

Know clearly it again, latch hook 11 of the present utility model offers a groove 12 in the bottom, its two side is offering a perforation 121 respectively near the place, centre position, 122, for penetrating a pin rod 15, the perforation 121 on right side is breakthrough status, the perforation 122 in left side then is non-through state, pin rod 15(is an irony) pass perforation earlier and 121 reach groove 12, pass rotor (roller again, utilize the zinc metal to make) 13 centre bore 131, and then penetrate in the perforation 122, it is fixing that last bar tooth by right-hand member again and perforation 121 are bitten, (it is to be pressed into impact style to block the location), so that rotor 13 is positioned in the groove 12, and form a spacing 14 with the upper end of groove 12, and to make rotor 13 be fixed rotating shaft with pin rod 15, and can do any forward and reverse rotation.

According to above-mentioned structure, when desire that leather suitcase cover is fashionable, utilize locking key 22 to buckle into, and make it to rotate (promptly just changeing), and can go deep into spacing 14(or groove 12 gradually by inclined-plane 23 friction rollers 13 of locking key 22 inboards from spacing 14) in, eventually to the state of fastening; In other words, can make case lid 1 and casing 2 can reach the effect that closely covers.

Otherwise when desire was opened leather trunk, then the unlatching by lockset made jam plate 21 utilize the elastic force of spring (this is the original accessory of general lockset, so not shown) and upwarps (as Fig. 1 state) automatically; In detail, i.e. locking key 22 makes its inboard inclined-plane 23 friction rollers 13 make it to be backward rotation by elastic force, thereby can promptly deviate from spacing 14, case lid 1 can be opened then, makes latch hook 11 break away from lockset.

So as can be known by above explanation, embodiment of the present utility model utilizes locking key 22 its inboards to have an inclined-plane 23, cooperate roller 13 itself can do forward and reverse rotation, covering of leather trunk fasten closely or the effect of separating thereby can reach easily, so that can reach tight and unlikely effect of killing.Therefore, not only simple structure, and effect is superior really, can be rated as one and has progressive and practical fine piece of writing.
