Abstract

The utility model relates to an improved pull rod base, which is composed of a base, an upper pull rod, a lower pull rod, an outer base body and a plurality of rolling wheels. The utility model is characterized in that a containing part and a wheel frame are arranged on the appropriate position of the base; the lower pull rod and the rolling wheel group are respectively pivoted on the containing part and in the wheel frame; the other end of the lower pull rod can be connected with the outer base body, and the rolling wheel group is pivoted on the appropriate position of the outer base body. When the improved pull rod base is used for carrying much luggage, the lower pull rod and the outer base body can be stretched outwards to increase the stationarity when the luggage is placed on the base to reduce the pushing force or pulling force which is needed by users. Simultaneously, the manufacturing cost can also be reduced.

Description

Improved bracket base

The utility model relates to a kind of daily necessities, refers to a kind of improved bracket base that is used for suitcase or suitcase transportation especially.

Bracket base structure at present commonly used please refer to Fig. 1, Fig. 2, shown in Figure 3, all be on appropriate location below the base, be pivoted with four groups of roller set 11 ' and two runners 12 ', so that in 2 ' time of carrying luggage, can make luggage 2 ' placed on it reposefully; But desire promotes 2 ' time of luggage, must be earlier with bracket base 1 ' past certain elevation angle that tilts so that runners 12 ' with ground 3 ' separate, can be with luggage 2 ' promotion; Therefore, following deficiency is arranged in use:

1, owing to bracket base commonly used is made up of base, lower link, preceding arm-tie, four groups of roller set and two runners; Because of part increases assemble man-hour more, increased manufacturing cost.

2, owing to when delivering more and heavy luggage, can make luggage press bracket base, and then bracket base is being supported by roller set and foot rest; When desire moves luggage, just must enforce or spur bracket base earlier, cause the operational inconvenience of user.

3, because its effort and operation are inconvenient, have increased the consumer and moved the time of moving luggage.

The purpose of this utility model is to provide a kind of improved bracket base, it not only has preferable smoothness when the more heavier luggage of carrying, and can reach parallel mobile laborsaving effect and increase convenience when manipulating, simultaneously, can also reduce man-hour and manpower required when assembling, and then reach the purpose that reduces cost.

The purpose of this utility model is to realize like this, a kind of improved bracket base, form by base, upper connecting rod, lower link, outer seat, roller set, the appropriate location of its base is provided with articulated section, holding part and wheel frame, so that upper connecting rod, lower link and roller set are hubbed in it, it is characterized in that: the other end of lower link is hubbed on the holding section of outer seat, and the appropriate location of outer seat is provided with the wheel frame, and roller set is hubbed in it.Lower link can be single formula or telescopic.

In conjunction with the embodiments the utility model is described in further details with reference to the accompanying drawings below.

1, base, 11, holding part, 12, recess, 13, the articulated section, 14, the wheel frame, 15, rivet,

2, upper connecting rod,

3, lower link,

4, outer seat, 41, the holding section, 42, the wheel frame,

5, roller set, 511, hole,

6, suitcase.

By shown in Figure 4, improved bracket base mainly includes base 1, upper connecting rod 2, lower link 3, outer seat 4 and roller set 5, the two ends system of base 1 is curved radian, so that cooperate the radian of suitcase both sides, and make suitcase can be limited to the top of base 1 really, be respectively equipped with holding part 11 and recess 12 on base 1 appropriate location, can be hubbed at respectively in holding part 11 and the recess 12 for lower link 3 and outer seat 4, on the base 1, be respectively equipped with articulated section 13 and wheel frame 14 on the appropriate location, below, be hubbed at respectively in articulated section 13 and the wheel frame 14 for upper connecting rod 2 and roller set 5.

Lower link 3 can be placed in the holding part 11 of base 1, and its other end then is hubbed on the outer seat 4, and lower link 3 can be single or stretch mode.

Outer seat 4 appropriate locations are provided with holding section 41, are hubbed in it for lower link 3, and the two ends of outer seat 4 are respectively equipped with wheel frame 44, are hubbed in it for roller set 5, and in addition, outer seat 4 just can be placed in the recess 12 of base 1 when shrinking.

When assembling pull bar group, only need lower link 3 is hubbed in the holding part 11 of base 1, and the other end that makes lower link 3 is hubbed in the holding section 41 of outer seat 4, make base 1 and outer seat 4 can adjust between the two distance by the telescopic action of lower link 3, at last, rivet 15 is penetrated in the hole 511 of roller set 5 again, make roller set 5 respectively riveted be positioned in the wheel frame 44 of the wheel frame 14 of base 1 and outer seat 4, and then reach the effect of this pull bar horizontal displacement.

As Fig. 5, shown in Figure 6, because lower link 3 is an extension type, therefore, when the more and heavier suitcase 6 of carrying, can make the loaded area deficiency of base 1, and outer seat 4 must be pulled outward, make lower link 3 can be stretched on the outside of the recess 12 of base 1, with the distance between increase base 1 and the outer seat 4, and increase the effect that it carries volume; When promoting suitcase 6, only need enforce upper connecting rod 2 slightly, bracket base 1 is moved.

By the above as can be known, the utility model has overcome the shortcoming of bracket base structure commonly used, and required part is few, can increase packaging efficiency, reduces production costs.

Because 4 of base 1 and outer seats are connected by lower link 3, and all are pivoted with roller set 5 below base 1 and outer seat 4, therefore, in use, need force in upper connecting rod 2, luggage is pushed, can reach the purpose of laborsaving promotion.
