Abstract

The utility model relates to a trunk pull-rod angle-regulating component. The utility model is characterized in that the utility model comprises a movable component which is positioned on a fixed component by a pin shaft. The fixed component is provided with at least one cambered surface towards the rotation direction of the movable component, and the cambered surface is provided with a notch. The center part of the movable component is through fitted with an elastic tongue which can be plugged into the notch for positioning. An inner rod is fixedly sheathed in the movable component during assemblage, while the fixed component is slidingly sheathed in an outer rod. The inner rod and an angle-regulating component both slide into the outer rod when a pull rod is folded; when the pull rod is pulled out, the movable component is pulled out by the inner rod correspondingly and the fixed component is just spaced at the upper end of the outer rod. At this time, the inner rod being pulled out oscillates strongly in transverse direction to overcome the elastic force of a spring inlaid in the elastic tongue, and the elastic tongue slide out of one notch into another notch, so the angle regulation of the pull rod is realized. When cooperated with a trunk with four corner wheels during use, the utility model is very convenient for pulling and pushing, and the height of the pull rod can be regulated correspondingly, so the utility model is suitable for people of different heights.

Description

Case drawbar angle modulation member

Technical field:

The utility model belongs to the case and bag field, particularly a kind of pull bar angle modulation member of compensation linkage angle.

Background technology:

Existing most case and bag all are equipped with pull bar and horn ring, realize rolling towing, and alleviate the journey hard work.Pull bar is the binodal structure, and small one and large one collapsible being concealed in the case and bag can conveniently be pulled out when needing, but pull bar can only be straight up and down at present.For the case and bag of the two horn rings certain angle that case and bag can be tilted, then could realize towing, if the case and bag of four horn rings, no matter its upright pull bar is to draw or push away, stressed distribution is all unreasonable, runs into little obstacle in the original state that moves or in sliding especially, all case and bag might be drawn overturning.Often can only bring by case and bag when mobile and realize that towing or directly promote casing slides it forward, this mode certainly will will be bent over and could operate, also fatiguability of a specified duration the adult.

Summary of the invention:

The purpose of this utility model is that a kind of pull bar of design is extracted the pull bar angle modulation member of back compensation linkage angle.

Technical solutions of the utility model are achieved in that a kind of case drawbar angle modulation member, it is characterized in that being positioned to form on the part by bearing pin by a moving part, deciding part is a cambered surface towards the moving part direction of rotation at least, cambered surface is provided with groove and lacks, moving part central authorities are equipped with the elasticity tongue, play the role of positioning but elasticity tongue insertion groove lacks the place.Rod member is fixed on the moving part in during assembling, and decides the part sliding sleeve in outer rod member.Rod member all slips in the outer rod member together with the angle modulation member in when pull bar is folding, when pull bar is extracted, interior rod member is taken advantage of a situation and is taken moving part out of, and decide the upper end that part is limited in outer rod member just, at this moment, the interior rod member of the extracting teeter of exerting oneself overcomes the built-in spring power of elasticity tongue, make the elasticity tongue skid off scarce another groove that enters of groove and lack, and the adjusting of realization pull bar angle.

The utlity model has reasonable in design, the angle modulation member is installed in the joint portion of pull bar two joints, can realize the angular adjustment of two joint pull bars, cooperate especially on the case and bag with four horn rings and use, no matter be pulling or promotion, can both case and bag be moved ahead, and the also corresponding realization of drawbar height be adjustable, be fit to the differing heights crowd and uses.

The specific embodiment:

See figures.1.and.2, a kind of case drawbar angle modulation member, be to be positioned to form on the part 2 by bearing pin 3 by a moving part 1, deciding part 2 is a cambered surface 21 towards the moving part direction of rotation at least, cambered surface 21 is provided with groove and lacks 22, moving part 1 central authorities are equipped with the elasticity tongue, play the role of positioning but elasticity tongue insertion groove lacks 22 places, pin the pull bar angle.

With reference to Fig. 2, outside deciding part 2, be arranged with a sliding sleeve 23, sliding sleeve 23 utilizes sliding sleeve 23 to cooperate with the pull bar rod member with decide part 2 fixing in aggregates, and realization slides up and down and is pinned by the rod member upper port.Deciding 23 fens body structures of part 2 and sliding sleeve mainly is to be convenient to processing.

With reference to Fig. 3, part 2 cambered surfaces 21 grooves of deciding of this legend lack 22 circular blind hole shapes, wherein decide the part cambered surface and are laid with two circular blind holes at least, and one is in vertically upward, another and first be in the 45 place, and all be on the moving part rotational trajectory.So at least, can realize the adjusting of the upright and inclination 45 of pull bar, and every increase by one circular blind hole can more than angle Selection.The quantity of circular blind hole shape groove scarce 22 is decided according to the arc length of cambered surface 21, generally gets 2 to 4 for good.

With reference to Fig. 4, part 2 cambered surfaces 21 grooves of deciding of this legend lack 22 one-tenth deep-slotted chip breaker shapes side by side, 3 one-tenth parallel shapes of deep-slotted chip breaker and bearing pin.The groove of deep-slotted chip breaker shape lacks 22 and acts on the same with the groove scarce 22 of circular blind hole shape.In addition, groove lacks 22 also can become serrate slot shape side by side, and serrate slot becomes parallel shape with bearing pin.

No matter groove is circular blind hole shape or deep-slotted chip breaker shape if lacking 22, its major function is to play the elasticity tongue of lock on the moving part, can be positioned on a certain special angle and make moving part and decide part.

With reference to Fig. 5, the elasticity tongue of moving part 1 central authorities is that a ball head 12 that exposes and built-in spring 4 are formed, and spring 4 one ends contact in moving part 1, and the other end contacts at ball head 12 rear portions, ball head 12 is remained expose.When firmly swinging moving part 1, ball head 12 can be decided the reaction force compressing retraction of part 2, and moving part 1 is rocked to down groove smoothly and lacks at 22 o'clock, and ball head 12 ejects once more, if shed the oscillatory forces on the moving part 1 this moment, ball head 12 lacks 22 with groove and cooperates lock toward moving part and the relative angular position of deciding part.Dotted line is represented another angle position of moving part among the figure.

With reference to Fig. 6, this legend is user mode figure of the present utility model, and the structure of another elasticity tongue is provided again.The elasticity tongue of moving part 1 central authorities is a steel wire 51, steel wire 51 passes hollow pull rod 5, and its other end extends in the horizontal handle 52 of pull bar, and affixed with horizontal handle 52 interior cross bars 54, cross bar 54 passes

press button

53, and 52 of press button 53 and horizontal handles are provided with and remain the outstanding spring 4 of press button.Press button 53 evagination all the time under spring 4 effect, and interlock cross bar 54 and steel wire 51, the bottom that makes steel wire 51 also is that the outstanding all the time insertion groove of elasticity tongue lacks in 22, having only down could release and regulate moving part and the relative angular position of deciding part by press button 53.This structure is sealed more stable, also is preferred plan.Only provide a side schematic diagram of case drawbar among the figure.
