A fixing tube and a positioning tenon accommodated at the end of the connecting rod and pushed by the pushing spring; the two side ends of the pull handle are accommodated in the straight groove on the top side of the telescopic rod and are embedded and linked with the tail end of the connecting rod, the tail end of the connecting rod is provided with a pushing plate with a middle-level drop, the pushing plate is bent and folded at the tail end of the first step surface to form an inclined surface, the tail end of the inclined surface is higher than the horizontal second step surface, and the pushing plate is provided with a through groove hole for the positioning clamping tenon to abut against the pushing plate; the connecting rod is pulled to link, so that the positioning latch on the first step surface is pushed by the inclined surface to move to the second step surface to retract the positioning latch into the fixing tube, so that the telescopic rod can be extended and retracted.

Description

Luggage case telescopic lever structure-improved

The utility model relates to luggage case telescopic lever structure-improved, especially the structure-improved that refers to the ejecting sheet of a kind of connecting rod end and location trip, structure interlock with simple and easy drop ladder is located the movable stud structure that trip substitutes the tradition complexity, makes that the assembling of pull bar group is more simple and easy, and cost more reduces.

Raising with work life gained, everyone improves gradually to the requirement of leisure quality, more and more many people's travel abroads, therefore the demand of luggage case thereby relatively raising, and luggage case is under within the trade is competed mutually, can bring into play under the identical function, structure is more simple, manufacturing cost is lower, and the competitiveness in market is also just strong; Especially in the design of luggage case telescopic lever structure, the structure of different vendor is not quite similar, yet for asking the favor that obtains the consumer, rack one's brains invariably, painstakingly, the consumer can be satisfied with, and need take into account manufacturing cost own, manufacturing cost own is reduced, lose competitiveness to avoid product; Therefore, the simplification improvement on structural design is to reduce the target that manufacturing cost is made great efforts by the dealer.

The purpose of this utility model is to eliminate the shortcoming of traditional telescopic lever structure, and in the hope of the table shape space of simplified structure, and the action effect that can reach expection promotes the competitiveness of product to reduce manufacturing cost.

Now join the thing accompanying drawing with regard to the structure of the utility model, form and be described in detail as follows:

Fig. 1: the assembled sectional view that is the utility model

Fig. 2: be the utility model pushing stopper and the combination stereogram of locating trip

Fig. 3: be the stereo appearance figure that the utility model supports sheet

Fig. 4: be that the utility model supports sheet and the action schematic diagram of locating trip

Fig. 5: be the telescopic lever constructional device in luggage case just, the side schematic diagram

See also shown in Figure 1ly, the utility model mainly comprises handgrip 20, draw 21, connecting rod 30, expansion link 25, stationary pipes 22 and the location trip 24 that places connecting rod 30 ends to be held bullet 23 ejections consist of;

Draw 21 two side ends are placed in the straight trough 261 of expansion link 25 top sides, be embedded interlock with the end of connecting rod 30, this draw 21 and 20 of handgrips be installed with spring 26, the lowermost end that 21 two ends is butted on straight trough 261 is drawn in ejection order by spring 26, in drawing the stopper slot 211 of 21 end face appropriate locations being established several depressions, establish a slotted eye 201 in handgrip 20, the push button 202 of the T-shaped shape of slotted eye 201 interior accommodating sections, the a pair of limited block 203 of answering stopper slot 211 shapes of push button 202 terminal lockings, this limited block 203 is subjected to the interlock of push button 202 and slides in the bottom surface of handgrip 20, and stopper slot 211 corresponding or blockings:

Establish the ejecting sheet 301 that is ladder tool drop and (please cooperate Fig. 2 at the end, connecting rod 30 end, shown in 3), second terrace, 302 ends of this ejecting sheet 301 are pulled folding and are an inclined-plane 303 and make and win, dual terrace surface 302,304 drops that are a suitable height, second terrace, 304 ends are made as and are up bending, establish a slotted eye that runs through 305 in ejecting sheet 301, make the location trip to receive into by the bottom surface of ejecting sheet 301, the flange 241 of trip 24 bottom surfaces, location is butted on slotted eye 305 sides, the bottom of location trip 24 embeds the end that holds spring 23, the end in addition that holds spring 23 is replaced expansion link 25, and order location trip 24 holds out against in ejecting sheet 301.

Elaborate with regard to its start principle of the present utility model below.

See also shown in Fig. 1,4, the position system location trip 24 of Fig. 1 is equipped in the locating hole 241 interior location expansion links 25 that fix of stationary pipes 22, the push button 202 of handgrip 20 is positioned at slotted eye 201 left sides simultaneously, break away from stopper slot 211 relative positions for interlocked limited 203, order draw 21 be subjected to limited block 203 restriction and can't start, be the locking state; See also Fig. 1 and Fig. 4 again, desire to hold up location trip 24 to break away from locating hole 221, make expansion link 25 be the state of scalable do action, be that push button 202 moves to right, make limited block 203 and draw stopper slot 211 corresponding 21, draw can connecting rod 30 be moved on the interlock thereupon: trip 24 initial systems in location be positioned at second terrace 302 of ejecting sheet 301, when moving on the connecting rod 30, inclined-plane 303 ejections are decided the flange 241 of trip 24 and are made location trip 24 move down compression with inclined-plane 303 to hold spring 23.Prop up when deciding trip 24 until second terrace 304 of ejecting sheet 301, the location trip holds in the spacing hole 251 stretch into expansion link 25 and breaks away from the locating hole 221 of stationary pipes 22, expansion link 25 can freely stretch in stationary pipes 22, work as length in expansion link 25 flexible reaching, pine oil pull handle 21, make spring 26 ejections draw replying and push away the connecting rod 30 of pulling to 21 and cover and return, the ejection that makes location trip 24 be held spring 23 returns back to second terrace, 302 positions by second terrace 304, location trip 24 receives in the locating hole 221 of stationary pipes 22 as shown in Figure 1, makes expansion link 25 location.

In addition, see also shown in Figure 5, be that the pull bar of the utility model Tiebar structure that contracts mainly is to be located at luggage case 10 inside to be close to the back side, make the telescopic lever structure be placed in and go within the case 10 except increasing luggage case 10 complete attractive in appearance, more avoid flexible stretching structure to be exposed to the outer invasion and attack that cause dust, and the shortcoming that gets rusty easily, make luggage case 10 more prolong its service life.

Therefore, by having following advantage in above-mentioned its global design of explanation this case:

1. utilize one hand can adjust pull bar for stationary state or be the flexible state of freedom, and be both to draw and be not subjected to interlock to 21, when preventing to drag luggage case and interlock draws 21 by push button 202 lockings.

2. spring 23 pushed against in ejecting sheet 301 when location trip 24 was pushed up, by the drop of first and second terrace 302,304 of ejecting sheet 301 and cooperate the pushing and pressing on inclined-plane 303, location trip 24 is reached shrink or spring into and fix in this locating hole of 22 221 and be able to freely stretch or locate expansion link.

Conclude, the utility model luggage case telescopic lever structure-improved, the design on first and second terrace of the ejecting sheet of its connecting rod end and inclined-plane, when control control the technological means of stretching or contracting its structure space and reaching of location trip in the connecting rod tension, really reach convenient and use, control easily.
