The specific embodiment

See also Figure 1 and Figure 2, the utility model be located on the suitcase pull bar 10 by manage on the base 11, handle 12, two manage in 13, two drive links 14, two neck bush 15, two 16, two two-way in members such as 17, two times pipes of cover, 18 and two spring elements 19 formed (, only pull bar 10 monolateral parts being done partly decomposition) for ease of explaining orally; Wherein can be ccontaining in the seat hole 111 on base 11 tops for handle 12, two inserted sheets 120 of handle 12 bottoms can insert in the pipe 13, two latches 121 run through pipe 13 pin-and-hole 131 respectively locatees with the pin-and-hole 1201 of inserted sheet 120, two times pipe 18 interlockings are below base 11, middle pipe 16 can stretch into down in the pipe 18, manage in 16 during last pipe 13 can stretch into, place the power transmission shaft 14 of pipe 13 inside, its top mat one boot last external member 141 links with the bottom of handle 12 buttons 122, and power transmission shaft 14 bottoms then mat one holder 142 combine with neck bush 15.

Cooperate shown in Figure 5, power transmission shaft 14 1 ends stretch in the bar cover 1551 of neck bush 15, pipe 13 bottoms are stretched on neck bush 15 tops, utilize an alignment pin 133 to run through pin-and-hole 132 of managing 13 bottoms and the perforation 1501 that runs through neck bush 15, and neck bush 15 is combined with last pipe 13, the solid sleeve pipe 150 of neck bush 15 tops cover, the mouth of pipe place on pipe 16 tops during this sleeve pipe 150 is mounted in, middle pipe mouth of pipe place, 16 nearly top has a locating hole 161, and this locating hole 161 can stretch out for the locating piece 153 that neck bush 15 1 ends protrude; A pair of is managed 16 bottoms during inwardly the top of cover 17 is stretched into, utilize an alignment pin 163 to run through the pin-and-hole 162 of middle pipe 16 bottoms and the jack 171 of two-way interior cover 17, make two-way in cover 17 combine with middle pipe 16, but briquetting 172 extrusion springs 173 on cover 17 tops move inward in two-way, and it is flexible to drive the locating piece 174 of its side; The solid sleeve pipe 170 of cover 17 tops and cover in two-way, this sleeve pipe 170 is mounted in down the mouth of pipe place on pipe 18 tops, and mouth of pipe place, following pipe 18 nearly top has a locating hole 181, and this locating hole 181 can protrude out for the locating piece 174 of cover 17 in two-way; One spring element (or spring) 19 is inserted down in the pipe 18, utilize an alignment pin 183 to run through the perforation 182 of pipe 18 bottoms down and the pin-and-hole 191 of spring element 19, and element 19 location of will bouncing are lived, these spring element 19 tops have elastic pressure bar 192, and spring element 19 inside can be stretched into to press a spring in its bottom; Managing the interlocking of 18 tops system down becomes one in the adapter 112 of base 11.

Travelling trunk pulling handle 10 go up pipe 13 and when pipe 18 does not stretch down as shown in Figure 1, the user works as by depressing button 122, power transmission shaft 14 can drive in the locating piece 15 of pipe 13 bottom neck bush 15 and contract, and 19 of elements of spring can drive pipe 13 and middle pipe 16 from pipe 18 ejections automatically down; For preventing that Travelling trunk pulling handle 10 is not when having squeeze grip 12 buttons 122 to land, pull bar 10 has automatic pop-up action, so the neck bush 15 (as Fig. 2) of design one innovation prevents that by the balancing weight 154 of neck bush 15 inside pull bar 10 from ejecting (as Fig. 3) automatically.

Consult Fig. 3 and shown in Figure 4, neck bush 15 of the present utility model comprises two enclosing covers 151,152, a positioning block 153, one balancing weight 154 and a slide bar 155, locating piece 153 1 ends protrude out the perforation 1511 of enclosing cover 151 sides, the other end pushes a spring 1531, these spring 1531 other ends prop up another enclosing cover 152 inboards, slide bar 155 1 ends place enclosing cover 151, in 152, the bar of the other end overlaps the 1551 protruding enclosing covers 151 that are exposed to, 152 outsides, can be nested with a spring 1552 in the bar cover 1551, can insert for balancing weight 154 in the frame groove 1553, the inclined-plane track 1554 of frame groove 1553 inboards can be flexible for locating piece 153, this inclined-plane track 1554 is made up of two long skewbacks 1555 and two short skewbacks 1556, short skewback 1556 bottoms also have rib 1557, button 122 when squeeze grip 12, withdrawn locating piece 153 smoothly just like the mode of slippery ladder in the inclined-plane 1532 of the inclined-plane track 1554 tangential locating pieces 153 of slide bar 155 by the perforation 1511 of enclosing cover 151, so that spring element 19 ejects handle 12 automatically, these balancing weight 154 both sides are provided with groove 1541 can supply enclosing cover 151 respectively, the raised line 1512 of 152 inboards is set, to make things convenient for balancing weight 154 slippages, balancing weight 154 front ends have pin 1542 can run through shrinkage pool 1513 on enclosing cover 151 columns 1514, is nested with a spring 1543 on the pin 1542 of balancing weight 154.

Consult shown in Figure 5, when suitcase (or pull bar 10) when being inactive state, the rib 1557 of inclined-plane track 1,554 two short skewbacks 1556 bottoms blocks locating piece 153, the pin 1542 of balancing weight 154 does not run through the shrinkage pool 1513 (pin 1542 does not block locating piece 153) on enclosing cover 151 columns 1514 at this moment, so normally the button 122 of squeeze grip 12 can inwardly withdraw locating piece 153, with stretching that handle 12 is provided and fold.

Consult shown in Figure 6, when suitcase is thrown by haul personnel carrying, pull bar 10 is subjected to collision on the ground, balancing weight 154 is extrusion spring 1543 automatically, 1542 of the pins of one end stretch out the shrinkage pool 1513 on enclosing cover 151 columns 1514, and block at locating piece 153 tail ends (as Fig. 7), make locating piece 153 can't in contract, so handle 12 can automatically not eject because of condition of poor.

In sum, the utility model system can prevent the device that Travelling trunk pulling handle ejects automatically, when suitcase is thrown (button of pull bar handle is not pushed down situation) by haul personnel carrying and when landing, the interior balancing weight of pull bar neck bush can prevent effectively that pull bar from ejecting automatically; The utility model is over and over again tested through the applicant, and function is all unquestionable, and the utility model is never made the city know or seen other publications, meets the regulation of Patent Law, proposes patent application then in accordance with the law.
