Description

The trunk draw bar positioning means

Technical field

The utility model provides a kind of trunk draw bar positioning means, the pressing member that espespecially can press on interior bar drives the continuous motion stem ejection in pusher shoe, and to make pusher shoe be that pushing part with support arm pushes against on slideway, make slip base towards the containing groove slide displacement of pedestal and block breaks away from the blocking hole in outer bar, reach with this pull bar is done the length adjustment location and reeled function.

Background technique

Social fast development and national dividend improve now, make people life style change gradually, and universal and more convenient because of various transport facilitys, no matter be at ordinary times for the needs on working, or the leisure of spending a holiday, travelling play to promote amusement and recreation etc., taking transport facility contact various places has become a thing very frequently, and all can use trunk, with required article that carry such as convenient for collecting clothing, articles for daily use, files.

moreover, but luggage case is formed with the containing space of items sheltering in the base inside of casing, and be covered with lid in the base upper cover, and be provided with plural roller bottom base and lid, the base back is provided with multi-section tie-bar, can make the function that length adjustment is located and reeled to multi-section tie-bar, be beneficial to the user by means of drawing on pull bar, making trunk be one tilts or vertical comes convenient plural roller to roll on the ground and suitable save time and than leicht fallen D/A, the pull bar positioning means that only should have trunk now is with the start in the guide groove of positioning pin of the salient point on connecting rod, and the drive positioning pin is made retract action, the salient point of this kind connecting rod is to act directly in the guide groove of positioning pin, just can cause connecting rod easily to lose efficacy because of the excessive generation structural damage of the application of force or fracture, overall structure is also unstable.

be with, just there is the dealer to develop existing draw bar structure of luggage boot for the shortcoming of above-mentioned pull bar positioning means, see also Fig. 9, shown in Figure 10, the three-dimensional exploded view of existing draw bar structure of luggage boot and the three-dimensional exploded view of fastening convex side, find out by knowing in figure, existing draw bar structure of luggage boot includes outer bar A, interior bar B and fastening convex side C, the two bridge A1 that wherein are somebody's turn to do outer bar A are provided with plural blocking hole A11, and two bridge A1 inside all are equipped with the bridge B1 of interior bar B, its bridge B1 is provided with blocking hole B11, and be provided with the continuous motion stem B3 that can drive for pressing member B2 in bridge B1 inside, fastening convex side C is arranged at respectively the bridge B1 inside of interior bar B, and has a left cap C 1, right cap C2, fastener C3, spring C4 and the push rod C5 that is socketed with spring C6 form, and the kelly C31 of this fastener C3 is the open-work C21 place that stretches out in right cap C2, penetrate again in interior bar B and outer bar A bridge B1, the blocking hole B11 of A1, forming blocking after in A11 locates.

when the pressing member B2 that presses on interior bar B as the user drives continuous motion stem B3 to bottom offset, its continuous motion stem B3 end just can ejection on push rod C5, and the inclined-plane C51 bottom push rod C5 pushes against after the inclined-plane C34 of fastener C3 top flange C33 is upper, can make the kelly C31 reverse displacement of blocking hole A11 of bar A outwardly of fastener C3, and the spring C4 that extruding fastener C3 locates with respect to kelly C31 opposite side groove C32 place is a resiliently deformable, and then the kelly C31 that makes fastener C3 breaks away from A11 place, blocking hole, do the adjustment of upper-lower position with bar B in convenient, though its can by push rod C5 push against in avoid on fastener C3 because of continuous motion stem B3 act directly on fastener C3 the situation of the structural damage that causes or fracture occur, but because the left cap C1 of fastening convex side C is to separate assembling to consist of with right cap C2, need to make more than at least two molds and cause degree of difficulty and cost on Design of Dies significantly to increase, overall structure comparatively complexity and member also more, also be unfavorable for assembling, to cause spent man-hour of assembling and cost to effectively reduce, and the mode of utilizing chimeric fixing because of left cap C1 with between right cap C is combined the location, when being subject to push rod C5 pushing and pressing, fastener C3 does the used time, just can cause left cap C1 easily to break away from right cap C2, and the stability of structure when affecting whole start, remaining to be engaged in this journey dealer redesigns effectively and is solved.

Therefore, model utility designer is because problem and the disappearance of existing draw bar structure of luggage boot, be to collect related data via in many ways assessment and consideration, and utilize the research and development experience for many years of engaging in the industry constantly study and revise, begin to design the novel birth of this kind trunk draw bar positioning means.
