Description

The detachable pulling rod structure

The utility model is a kind of detachable pulling rod structure, especially refer in particular to title and be provided with pedestal on the surface of luggage case, and in pedestal top making and settlement T type convex body, allow at the bottom of the swivel base corresponding tenon just in the rotatable T of the being fixed in type convex body or rotation take out, and make groove in base bottom, usefulness for installing keeper and spring, right this keeper is provided with the reference column that passes T type convex body, can block the pulling rod structure of the detachable in the locating hole that bullet is fixed in the swivel base correspondence simultaneously by the reference column of keeper by the spring-go tension force of spring.

The pull bar major part that tradition is commonly used all is arranged on the inside of luggage case, Jing and cause the inner space of luggage case to be occupied by pull bar, except meeting reduces in the luggage case the utilizable space, simultaneously must additionally in the inside of luggage case the plate face be set pull bar is hidden, the necessary public luggage case of the length of the pull bar of commonly using in addition is contour.

In view of this, this creation proposes a kind of detachable pulling rod structure.

Main purpose is: pull bar is arranged on can dismantles on the swivel base that takes off, and be provided with pedestal in the surface of luggage case, the center of top place system of right this pedestal is provided with a T type convex body, allow the corresponding tenon of swivel base bottom just in the rotatable T of the being fixed in type convex body, when not using pull bar, only need reverse rotation to make things convenient for easily and take out swivel base, make groove in the bottom of pedestal simultaneously, usefulness as installing keeper and spring, and be to be provided with reference column on this keeper, can be fixed in the locating hole of swivel base correspondence by the spring-go tension force of spring reference column card bullet, form the fixation that the rank fabrication is closed keeper; This creation is arranged on pull bar on the luggage case, except use in the space that can increase trunk internal, can reduce the pull bar length of half at least again.

For structure content of understanding this creation in depth and the function and benefit that can reach, enumerate a specific embodiment now and cooperate graphic detailed introduction to be described as follows:

A kind of detachable pulling rod structure, as shown in Figure 1: the perspective exploded view that is this creation.Its structure mainly tie up in: this pull bar comprises that element institute common combinations such as a handgrip 10, an inner sleeve 20, an outer tube 30, a swivel base 40, a pedestal 50 form; Wherein:

Handgrip 10, can be for the usefulness that grips the push-and-pull luggage case, and the sleeve pipe 11 of a hollow is extended at the place in the middle of handgrip 10 belows, system locks the roped party integrators by screw P with handgrip 10 public inner sleeves 20 simultaneously for the usefulness of sheathed connection one inner sleeve 20, and makes a perforation 12 handle 10 middle giving a farfetched interpretation, usefulness as installing button 13, certain pull bar 14 is set up in right this button 13 bottoms extension, digs at the end of deciding pull bar 14 in addition and establishes a circular arc pearl groove 15, for the usefulness of burying a location steel ball 16 underground;

Inner sleeve 20, it is the hollow tube of a suitable length, upper end system lock knot is fixed in the sleeve pipe 11 of handle 10, the sheathed cock body 21 in lower end, and in cock body 21 a sheathed spring 22, as the above-mentioned usefulness of deciding pull bar 14 of spring-go, and the tube wall below inner sleeve 20 is drilled with a hole 23, above-mentioned positioning ball 16 just can be ejected in the hole 23, as the usefulness of card bullet location outer tube 30;

Outer tube 30, be a suitable length hollow tube, can supply the sheathed from lower to upper insertion of inner sleeve 20, and be drilled with two locating

holes

31,32 in the top and the appropriate position, below of outer tube 30, allow inner sleeve 20 stretch out or during retraction positioning ball 16 just can eject and be positioned the upper and lower locating

hole

31,32 of outer tube 30, outer tube 30 is plugged be fixed in the swivel base 40 simultaneously;

Swivel base 40, a base 41 is set up in the position therebetween, above-mentioned outer tube 30 just can be plugged in the base 41 that is locked in swivel base 40, and in the corresponding position, both sides of swivel base 40 bottoms making and settlement tenon 42, supply to hold in the mouth the usefulness that fabrication is fixed in pedestal 50, and be drilled with three locating

holes

43,44,45 at the place, centre position of swivel base 40 bottoms;

Pedestal 50, appropriate position around it is drilled with perforation 51, can be fixed on the luggage case 60 by screw P lock knot, and set up T type convex body 52 in place, the centre position at pedestal 50 tops, two tenons 42 of correspondence of above-mentioned swivel base 40 bottoms just can be rotated to be fixed in the T type convex body 52, and make link stopper 521 on one side at T type convex body 52, on T type convex body 52, run through three open-works 522 in addition, 523,524, establish a groove 53 in the place, centre position of pedestal 50 bottoms cutter in addition, as burying a positioning piece 54 and a spring 55 underground, right this keeper 54 ties up to the open-work 522 corresponding to T type convex body 52,523,524 places set up three reference columns 541,542,543, allow keeper 54 can utilize the spring-go effect of spring 55, make corresponding reference column to eject, the card bullet is fixed in the locating hole 43 of above-mentioned swivel base 40 bottoms, 44, in 45, lock in groove 53 more at last and tie fixed head face 56.

This that combines by above-mentioned each component arrangement is created a kind of detachable pulling rod structure, as shown in Figure 2: the section combination schematic diagram that is this wound.Shown in Figure 3: the enforcement schematic diagram that is this creation.On practical operation is used, the user can be fixed in tenon 42 rotations of swivel base 40 two bottom sides in the T type convex body 52 of pedestal 50, form one and hold in the mouth the fixing bonding state of system mutually, only need press button 13 by handgrip 10 to drive during use to decide pull bar 14 and be shifted downwards, allow the arc groove 15 of backstay 14 belows descend, make hole that backstay steel ball 16 is embedded in inner sleeve 20 along 23 and arc groove 15 in, make this positioning ball 16 break away from the locating hole 32 blockings relation of public outer tube 30, use stretching inner sleeve 20 to suitable length, when the user no longer presses by this button 13, the spring 22 of inner sleeve 20 bottoms promptly can eject backstay 14 and button 13, allow positioning ball 16 again ejecting card be fixed in the locating hole 31 of outer tube 30 tops, when the user does not re-use pull bar, only needing that swivel base 40 is rotated taking-up on pedestal 50 gets final product, the detachable pulling rod structure that this creation provided, occupy luggage case 60 volume inside except saving pull bar, can reduce pull bar length again, have the practicality effect and promote effect.

Comprehensive above-mentioned institute is old, this creation system provides a kind of detachable pulling rod structure, through this creator actual manufacture finish and the repetitiousness operational testing after, confirm that can reach this really creates desired function and benefit, do not create earlier first of the information in the streets still having at present again simultaneously, have the value on the industry, met the main idea of practicality territory progressive.
