Description

The Travelling trunk pulling handle positioner

The utility model relates to a kind of Travelling trunk pulling handle positioner, belongs to a kind of annex of people's travel goods.

Existing Travelling trunk pulling handle device, as shown in Figure 1, be on handle 1, to establish a control pressing plate 11, in pressing plate 11, be provided with the linkage (not shown), respectively be equipped with pipe 2 in addition in handle 1 two side ends bottom surface, interior pipe 2 upper limbs are provided with pad 22, be provided with a trace 21 in the pipe, pipe 2 was to interior card pipe 3 in trace 21 ran through from handle 1 inside, and the lower end is connected with pushing block 33, the lower end of pipe 2 in interior card pipe 3 is sheathed on, on the tube wall of interior card pipe 3, be provided with hole clipping 31, be provided with clamping block 34 in the hole clipping 31, apical grafting clamping block 34 upper ends be pushing block 33, manage 3 bottoms at interior card and be provided with heelpiece 35 and be used for the card knot pad 36 of back cover, card knot pad 36 is provided with two relative cards knot hooks 361, in card knot pad 36 is hooked in card knot hook 361 in the dog hole 32 of card pipe 3, interior pipe 2 is placed in the outer tube 4, is arranged with locating hole 41 on the tube wall of outer tube 4.

Referring to Fig. 2, when need are adjusted pull bar length, hold handle 1 by pressure-controlled pressing plate 11, control pressing plate 11 drive linkages press down trace 21 and drive pushing block 33 incisions then, clamping block 34 is inwardly shunk in the pipe 2, and at this moment interior pipe 2 just can slide in outer tube 4; When desiring steady brace, the control pressing plate 11 of handle 1 to be decontroled, each spring recovers original elastic force, trace 21 resets, and clamping block 34 stretches out hole clipping 31 again and snaps in the locating hole 41 of outer tube 4, reaches the location purpose, as shown in Figure 3, there is following shortcoming in said structure:

1, when controlling pressing plate 2 when pressing down, borrow trace 2 to make pushing block 33 and clamping block 34 inconsistent, but the groove 341 that a sheathed spring 342 is arranged for 34 times because of clamping block, when trace 21 is pressed down, clamping block 34 has crank and upwarps phenomenon, as shown in phantom in Figure 3, make clamping block 34 be difficult for retraction smoothly, pull bar can't rise or descend smoothly.

2, trace 21 is to combine with screw thread with pushing block 33, and trace 21 and 11 of pressing plates of control are conflicted and do not had a location really, when trace 21 about number of times too much, often trace 21 and pushing block 33 break away from looseningly, the location is forbidden.

The purpose of this utility model is that a kind of robust Travelling trunk pulling handle positioner will be provided, and its action is infallible, easy to use.

The purpose of this utility model is achieved in that the Travelling trunk pulling handle positioner, by handle, transmission device, trace, interior card pipe, interior pipe and outer tube constitute, pipe bottom in interior card pipe is fixed in, in card pipe one side open the open-work that lower edge on is provided with limited block, the opposite side opening covers with snap-on caps, being provided with in the interior card pipe is placed on the limited block and the slide that can slide up and down, be provided with skewed slot in the slide, the location-plate of locating piece can slide on skewed slot by oblique guide pillar, and borrow between slide and interior card pipe spring to make location-plate stretch into the open-work of inner and outer pipes and locate, pull bar length is maintained static, when the trace pressurized, then contract in the location-plate, interior pipe can slide in outer tube and change pull bar length.

The utility model vertically withstands under the interior driver blade of handle because of the trace in the pipe in being located at, trace vertical depression when pressing control knob instantly, make slide descending, and be provided with the spring that makes the slide vertical lifting under the slide and between interior card pipe, slide can steadily be risen, it is flexible to drive in the locating piece location-plate, so but in the utility model used positioner average force also can reach locating effect really and sturdy and durable.

The utility model concrete structure is provided by following examples and accompanying drawing thereof:

4,5,6.

The Travelling trunk pulling handle positioner, by in 5, transmission device 6, interior pipe 8, trace 7, outer tube 9 and be fixed in manage 8 bottoms 81 of interior card pipes constitute, it is characterized in that:

Handle 5 is a bar shaped housing, form with rivet 53 riveteds by upper cover body 51 and lower cover 52, transmission device 6 is made of the bar shaped driver blade 62 and the spring A that are located in the handle 5, driver blade 62 central authorities are provided with the control knob 61 of projection, it is overhanging that control knob 61 passes the open-work 511 of upper cover body 51, spring A upper end withstands in the control knob 61 inner grooves that form, and the spring A other end is enclosed within on the projection 521 in the lower cover 52;

Lower cover 52 bottoms of handle 5 are fixed in outer tube 9 upper ends, on the tube wall of outer tube 9, are arranged with the locating hole 91 for horizontal location plate 831 engagings of locating piece 83;

Interior pipe 8 is placed in the outer tube 9, and insert in the perforation 522 of lower cover 52 interior pipe 8 upper ends, the 81 one-tenth tight fits in interior pipe 8 lower ends and interior card pipe;

Manage in 8 in trace 7 is located at, trace 7 end faces prop up driver blade 62, on the slide 82 in card pipe 81 tops withstood on and are located in the lower end was passed in the card pipe 81, the pad figure circle 71 that has dogging shoulder and groove is passed at trace 7 tops, interior pipe 8 upper ends withstand on the packing ring 71, spring B is located in the groove of packing ring 71, and the spring B upper end withstands on the top of trace 7; The lower end of pipe 8 in interior card pipe 81 is installed in, side at interior card pipe has open-work 811, lower edge on open-work 811, be respectively equipped with inwardly protruded limited block 812,813, the opposite side of interior card pipe 81 is open shape, on the inwall of opening, be provided with slot 814, a side of pipe 81 in snap-on caps 815 is fastened on for 815 inwardly protruded caking block 8151 engagings of cambered surface snap-on caps;

Slide 82 is a bar shape, in the card pipe 81, be provided with groove 821 in the slide 82 in being sheathed on, groove 821 length are greater than the spacing of interior card pipe limited block 812,813 about in the of 81, be provided with skewed slot 822 at groove 821 middle parts, manage at slide 82 bottom surfaces and interior card spring C is housed between 81 bottom surfaces;

Locating piece 83 lower ends are horizontal location plate 831, location-plate 831 passes the open-work 811 of interior card pipe 81 and stretches in the locating hole 91 of outer tube 9, be provided with skewed slot 822 corresponding oblique guide pillars 832 with slide 82 in locating piece 83 nearly centre, the other end of location-plate 831 is linked in the location of sliding in the groove 821 of slide 82.

When the utility model uses, push control knob 61, driver blade 62 stressed pressing down then, the trace 7 stressed slides 82 that make in the interior card pipe 81 that press down are descending, cause at this moment locating piece 83 is to be inserted in the skewed slot 822 of slide 82 with guide pillar 832, so locating piece 83 must move with the descending of slide 82, because of this locating piece 83 is to be set in the open-work 811 of interior card pipe 81 with location-plate 831, and be subjected to, lower position block 812,813 spacing, so when slide 82 is descending, borrow cooperating of skewed slot 822 and guide pillar 832, make in the locating piece 83 and contract, then location-plate 831 breaks away from the locating hole 91 of outer tube 9, and just interior pipe 8 can freely stretch in outer tube 9.

Otherwise, when external force disappears, then control knob 61 borrows spring A to reset in the transmission device 6, slide 82 also borrows spring C to rise, locating piece 83 rises because of slide 82 skewed slots 822, its guide pillar 832 is pushed laterally because of gradient, force the location-plate 831 of locating piece 83 to engage with the locating hole 91 of outer tube 9 and make in pipe maintain static.
