Description

The master and slave type suitcase of the improved male and female fastener of tool

The utility model relates to suitcase, refers to a kind of mutual fastening that utilizes the male and female fastener especially, reaches the suitcase of separating or make up the primary and secondary casing rapidly.

Though composite box slide fastener commonly used can bear the storing weight, but separate or in conjunction with the time need with slide fastener around the whole box body outer rim, so cause the problem that wastes time and energy on the group program of tearing open, moreover, if use the connection fastener of magic tape, though have the advantage that can tear group rapidly open, magic tape can't bear heavier article, when the built-in article of factor casing surpass constant weight (as notebook computer) or suffer the exerting pressure when pushing of external force, cause the primary and secondary casing to separate the phenomenon that comes off easily.

In view of this, for solving the variety of problems that above-mentioned connection fastener commonly used is produced, thereby develop a kind of easy, wieldy male and female fastener of group of tearing open, make it easy to tear open group and can bear the load of putting gravity.

Again, the combination of male and female fastener commonly used be adopt with pin thread be arranged on female casing, box then is arranged at the design on the sub-casing, latch during its both snappings in the pin thread is to be inserted in the box with in conjunction with the primary and secondary casing, and main stress point is at the opening part of box, and the latch eye-splice of pin thread is also born the whole weight of sub-casing, increase the male and female fastener and can bear bigger gravity for making under the topic before reaching the purpose that is easy to tear open group, the utility model promptly is primarily aimed at master and slave type travel box male and female fastener commonly used and gives improvement again.

Main purpose of the present utility model is at the master and slave type suitcase that the improved male and female fastener of a kind of tool is provided, and this male and female fastener has enlarged male and female fastener bonding area, can strengthen the intensity of fastener own.

Another purpose of the present utility model is at the master and slave type suitcase that the improved male and female fastener of a kind of tool is provided, and this male and female fastener is cheap for manufacturing cost, simplifying of fastener inner body.

For reaching above-mentioned purpose, " the master and slave type suitcase of the improved male and female fastener of tool " of the present utility model is the male and female fastener that is provided with mutual correspondence respectively at sub-casing and female casing, but these pin thread both sides are provided with the blocking part that the pressing bullet is stretched, the box both sides then are provided with hollow part, by the mutual fastening of male and female fastener, separate the purpose that is easy to tear open group primary and secondary casing to reach.

Pin thread on this sub-casing is when box on female casing engages, the blocking part of pin thread is closely buckled in the hollow part of box, its stress point is the snapping face of blocking part and hollow part, thereby the barb that mutually the snapping area is commonly used goes out manyly greatly, bears the effect that the external force situation also has obvious reinforcement.

The utility model also can be set up the braces that two ends are provided with box in addition, and the pin thread of sub-casing can be provided with the braces snapping of box with two ends, and portable is used sub-casing separately.

Also convertible the establishing of box tool on female casing is as box form commonly used for the pin thread fastening, box that should be commonly used is textural mainly to be to have a pedestal, this pedestal one end is to be fixed on the casing, and pedestal is provided with a snapping portion for the winding pin thread, is provided with elastic arm in these snapping portion both sides again.

Below now with regard to the novel structure function of this usefulness, adopt a preferable feasible embodiment, after conjunction with figs. was described in more detail in, making increased understanding of the present utility model:

The accompanying drawing simple declaration:

Fig. 1: be primary and secondary casing schematic perspective view of the present utility model;

Fig. 2: be male and female fastener schematic perspective view of the present utility model;

Fig. 3: be male and female fastener combination dissected figure of the present utility model;

Fig. 4: for of the present utility model another implemented example;

Fig. 5: be the utility model neutron casing and braces combination schematic diagram.

The figure number explanation:

10 ... female casing 32 ... socket

20 ... sub-casing 33 ... hollow part

21 ... braces 40 ... pin thread

30 ... box 41 ... blocking part

31 ... fixed head 42 ... the on-slip splenium

311 ... perforation 50 ... box

See also as can be known shown in Figure 1ly, suitcase of the present utility model mainly includes a female casing 10 and a sub-casing 20; The four side of wherein female casing 10 is respectively to be provided with a box 30 for connexon casing 20, this sub-casing 20 is can be for placing notebook computer, and the box 30 that then is provided with female casing 10 near faying face of female casing 10 in the middle of its outside, four limits ora terminalis is corresponding pin thread 40.

Please cooperate and consult Fig. 2, shown in Figure 3, the both sides of box 30 are provided with the fixed head 31 of protrusion, it is provided with some rivets that place and is fixed in perforation 311 on the casing, these box 30 front ends are provided with one and engage the socket of planting 32 with pin thread 40, and are provided with the usefulness that hollow part 33 is stretched fastening for pin thread 40 bullets in centre position, box 30 both sides;

But these pin thread 40 both sides are provided with the blocking part 41 that the pressing bullet is stretched, and the outside of this blocking part 41 is provided with card sliding pressure portion 42, in the present embodiment are to be designed to serrated surface (can certainly other shape that can increase friction replace).

Pin thread 40 insert boxes 30 in conjunction with the time, the blocking part 41 of these pin thread 40 both sides is promptly oppressed simultaneously and is inwardly contracted in placing socket 32 ports, 41 outside bullets of blocking part are stretched during hollow part 33 in being inserted in box 30, and are fastened on and make it to be fixed in the box 30 in the hollow part 33; During male and female fastener on will separating the primary and secondary casing, press the on-slip splenium 42 in blocking part 41 outsides in only needing, just can make and contract in the blocking part 41 of pin thread 40 and break away from box 30.As shown in Figure 4, its box 50 can be established to be as box pattern commonly used and also can fasten for pin thread 40.

See also shown in Figure 5, after above-mentioned sub-casing 20 is separated with female casing 30, but winding one braces 21 uses separately, it is in braces 21 2 ends the box 30 that is same as on female casing to be set directly, be fastened on pin thread 40 on the sub-casing 20 by the box 30 at braces 21 two ends, braces 21 connect be fixed on the sub-casing 20; If need braces 21 is separated sub-casing 20, also can pin thread 40 be withdrawed from box 30 according to the identical mode of separating of above-mentioned male and female fastener.

Above disclosed content only is a preferred embodiment of the present utility model, when can not with the scope implemented of qualification the utility model; Be that all equalizations of being done according to the technical solutions of the utility model scope change and modify, all still belong in the scope that technical solutions of the utility model contain.
