The self-fastening and locking anti-disengagement buckle for a suitcase can be particularly used for special suitcases having high sealing requirements and self locking anti-disengagement requirements.

Description

Case and bag are from tension and self-locking anticreep released hasp

Technical field

The utility model relates to a kind of hasp, and particularly a kind of case and bag are from tension and self-locking anticreep released hasp.

Background technology

What mostly present case and bag were by the adjustment hasp when straining and realize the installation site between having contact with, not easy to operate when installing and using, hypertelorism is tension then, hypotelorism is then loose excessively, particularly on the higher case and bag of some sealing requirements, adjust tightness and realize sealing and be difficult to realize by adjusting distance, the anti-disengagement functional group of existing hasp additionally locks on this and finishes in addition.A kind of no key hasp that is used for case and bag is disclosed in Chinese patent 96206611.7, its technical scheme that adopts is in the lock matrix slidably switch lock metal tool to be set, the rear end that the lock of switch lock metal tool is inserted in the operation panel at slotted hole place makes it link to each other with switch lock metal tool, serving as that axle closes up the start plate to the front end of operation panel with the lock matrix, to make the tying sheet serve as that axle rotates and hooks it with the lock matrix to the hook that draws that is provided with at the front end back side of operation panel.When depressing the start plate, draw hook and separate with the tying sheet, its intermediary's free plate and tying sheet are one.Its shortcoming is that complex structure, part are many, the production costs costliness, and assemble loaded down with trivial details.

Summary of the invention

In order to overcome the problem that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of simple structure, part few, and cost is low, and case and bag easy to assembly are from tension and self-locking anticreep released hasp.

The technical solution of the utility model is that these case and bag are from tension and self-locking anticreep released hasp, comprise from take-up device and anti-disengaging gear, it is characterized in that describedly forming by stage clip chamber, stage clip, hasp nose from take-up device, the stage clip chamber is the square structure of hollow, match and hasp nose that main body framework is the frame type places in the stage clip chamber by two slits, side, stage clip chamber with having contact with, in the hasp nose and between hasp nose inner bottom plating and stage clip chamber side panel, be equipped with stage clip; Described anti-disengaging gear comprises that the anti-avulsion sheet that is arranged on the gland reaches the anti-avulsion that is positioned on the base side wall that matches with the anti-avulsion sheet and colludes, anti-avulsion sheet one end stretches out from gland sidewall bar seam, the other end is hinged on the gland inboard by screw, is provided with that an end is limited in the gland inner surface and the other end is hooked in the torsion spring on the anti-avulsion sheet at gland between the inboard and anti-avulsion sheet and by aforementioned screw; Gland and base all are U type and inside and outside containing, by partly selling hinged; The stage clip chamber is positioned at base, and is hinged by the bearing pin that is positioned at the hasp nose inner bottom plating outside between stage clip chamber and the gland; Be arranged with the arc groove corresponding at base side wall with bearing pin.

For ease of operation, described anti-avulsion sheet outer end is provided with handle.

The beneficial effects of the utility model are: it is pure frame for movement, by clasp inner chamber mounting spring, realize the tension certainly of hasp, collude the self-locking that interoperation is realized hasp by the anti-avulsion of anti-avulsion sheet on the hasp gland and base, thereby solved that existing hasp can't be strained and can't the anti-shortcoming of throwing off of self-locking.Simultaneously simple in structure, part is few and make simply, and cost is low, and is easy to assembly, uses easy to operate, tension reliably, but the self-locking anticreep, fault rate is low.Higher in particular for seal request and have the anti-disengagement of self-locking to require extraordinary case and bag.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the stereogram (partial cutaway) of the utility model hasp;

Fig. 2 is the longitudinal sectional view of the utility model hasp.

1 have contact with among the figure, 2 hasp noses, 3 stage clips, 4 bearing pins, 5 half pins, 6 glands, 7 torsion springs, 8 bases, 9 anti-avulsion sheets, 10 stage clip chambeies, 11 anti-avulsions collude, 12 screws, 13 have contact with fixing hole, 14 base fixing holes, 15 grooves.

The specific embodiment

As shown in Figure 1 and Figure 2.

These case and bag comprise from take-up device and anti-disengaging gear two large divisions from tension and self-locking anticreep released hasp.

Describedly form by stage clip chamber 10, stage clip 3, hasp nose 2 from take-up device.Stage clip chamber 10 is the square structure of hollow, with be fixed on case and bag on cover have contact with and 1 match and hasp nose 2 that main body framework is the frame type places in the stage clip chamber by slit, both sides, 10 side, stage clip chamber, in hasp nose 2 and between hasp nose inner bottom plating and stage clip chamber side panel, be equipped with a plurality of stage clips that are arranged side by side 3.

Described anti-disengaging gear comprises that the anti-avulsion sheet 9 that is arranged on the gland 6 reaches the anti-avulsion that is positioned on base 8 sidewalls that matches with the anti-avulsion sheet and colludes 11.Anti-avulsion sheet 9 one ends stretch out and are provided with handle from gland sidewall bar seam, the other end is hinged on gland 6 inboards by screw 12, is provided with that an end is limited in the gland inner surface and the other end is hooked in the torsion spring 7 on the anti-avulsion sheet at gland 6 between the inboard and anti-avulsion sheet 9 and by aforementioned screw 12.Gland 6 all is the U type with the base cross section and gland contains base 8, and the two is hinged by partly selling 5.Stage clip chamber 10 is positioned at base 8, and is hinged by the bearing pin 4 that is positioned at the hasp nose 2 inner bottom platings outside between stage clip chamber 10 and the gland 6; Bearing pin 4 is positioned at the end in stage clip chamber, and its position can make hasp nose 2 scope rotation at a certain angle in base; In order to adapt to this rotation, be arranged with the arc groove 15 corresponding with bearing pin 4 at base 8 sidewalls.

Take structure 1 usefulness screw by have contact with fixing hole 13 be fixed on case and bag on cover, comprise that hasp assembly from take-up device and anti-disengaging gear is fixed on the following of case and bag with screw by base fixing hole 14 and covers, suitably adjust distance.When gland 6 started, hasp nose 2 did not stress, and stage clip 3 is in relaxation state; When gland 6 is pressed following time, gland is that fulcrum moves backward by bearing pin 4 pulling stage clip chambeies 10 partly to sell 5, has contact with on 1 because of hasp nose 2 hangs over, so stage clip 3 is compressed, the active force of stage clip 3 makes to be realized between the upper and lower cover from tension; When gland 6 is depressed, for preventing that external force factor from touching gland 6 and making it to start, on gland 6, installed anti-avulsion sheet 9 again, under the effect of torsion spring 7, anti-avulsion sheet 9 is that bullet is tight forward all the time, when gland 6 is pressed following time, anti-avulsion sheet 9 and the anti-avulsion of base 8 sidewalls are colluded 11 hooks mutually, thereby play the anti-purpose of throwing off of self-locking.
