Description

Hand cart with seat structure

The utility model relates to a kind of hand barrow with armchair structure, mainly is with the gradually little or elongation of spacing of amounting to or launch to drive wheel between pole and up-and-down rod, can conveniently fold and strengthen stable area; In addition the relation between seat and up-and-down rod is changed into two slide tube types and more can increase the steadiness that bearing force and chair move.

" hand barrow " application for a patent for invention case of the applicant's what in July, 92 29 day number of filing an application once 92108781.0 with folding seat, this case mainly is by hand barrow and seat be combined into, wherein the bottom bar of hand barrow articulates transverse supporting rod in slide cartridge, the transverse supporting rod top connects solid with seat, if a JiongXing Jia is articulated with rocking bar downwards, the end in addition of this rocking bar is socketed on connecting rod, so when seat folds, can order about the back support foot rest and move by the mutual interlock of JiongXing Jia, rocking bar and connecting rod with seat; The top of support foot rest is articulated on the slide cartridge in addition, with a packing ring two support foot rests is separated and articulates in midway location, and transverse supporting rod can be by outside direct control in the work that makes riveted JiongXing Jia and rocking bar because of being provided with groove again.

The aforementioned patent applications case is opened when moving with folding very simple and easy in operation, be about to be in the hand barrow of chair collapse state when desiring to open, need only can drop to fixed point by transverse supporting rod interlock slide cartridge with proposing folding on the seat, pressing down seat this moment contacts with the top of back support foot rest, end by the back support foot rest is articulated on the axostylus axostyle of hand barrow roller in addition, and utilize the back strong point of two rollers as seat pressurized strength, preceding support foot rest also produces the displacement of upholding forward because of the decline that is subjected to slide cartridge, when slide cartridge is located, preceding support foot rest also opens the firm support that formation forward contacts with ground fully, so can be by preceding, the formed firm support face of back support foot rest and seat, make and evenly to be supported via the weight that seat bore, and do not have the anxiety of avalanche, again when folding seat, also need only carry seat upwards, can drive slide cartridge rises to the location and folds preceding support foot rest simultaneously, inwardly be pressed into seat this moment again, making rocking bar drive the back support foot rest inwardly folds, when the groove of seat snaps in the packing ring, the whole process that folds is promptly finished, and it is quite convenient and practical on manipulating.

But it is perfect that above-mentioned patent application case is not attained in the structure configuration yet, and still have following all shortcoming:

1. two of hand barrow take turns apart from limited, not so that unlikely transport not steady that cause of article fashion of carrying smaller size smaller, but if when being used in the article of carrying larger volume, because of the outstanding car body of the width of article a lot of, so original two take turns distance will be because of too small instability when causing car body to walk.

2. general baggage car base is little, when loading more article and on Uneven road or slope, walking, and effort and unstable not only.

3. so seat is when opening and closing and folding, because slide cartridge only has one, its bearing force is limited, damages be subjected to easily to use improperly and the stationarity of slippage is still disliked deficiency.

Main purpose of the present utility model is: a kind of hand barrow with armchair structure is provided, it will be pivoted with the wheel bar on the reinforcement frame, this is taken turns the bar end and connects and establish wheel, establish a pull bar at wheel bar place in addition, pull bar is to join with pole simultaneously, then pole can drive two in folding or when launching and take turns folding or space out, with reach that folding does not take up space and expanding wheel apart from strengthen increase advance between stable advantage.

Another purpose of the present utility model is: a kind of hand barrow with armchair structure is provided, it is provided with the reinforcement frame on up-and-down rod, in addition the structure of two slide cartridges of design and slide bar can make chair not be subject to improperly the application of force and damages to drive the terminal slippage of chair strut bar reposefully on up-and-down rod again.

The utility model provides a kind of hand barrow with armchair structure, mainly is to be provided with two poles and up-and-down rod, and wherein the latter is pivoted with basket support in the one side, and other side then is provided with the chair pin-jointed structure and movable Zhe chair joins, and its principal feature is:

Two up-and-down rods are articulated with one respectively in the proximal end both sides and take turns bar, and this is taken turns, and bar is terminal to join with wheel, is pivoted with pull bar at the wheel shaft place simultaneously, and pull bar end in addition then joins with pole; Be pulled upwardly to be at pole and be connected into one, promptly drive pull bar and the traction wheel bar, and drive wheel and upwards mention and outwards open, otherwise then wheel can be folded with up-and-down rod.

The hand barrow of aforesaid tool armchair structure, its characteristics are: up-and-down rod is provided with the reinforcement frame in the bottom, and this reinforcement frame is with the reinforcement of up-and-down rod clamping.

The hand barrow of aforesaid tool armchair structure, its characteristics are: two up-and-down rods have been horizontally set with radius stay between the top, which is provided with a tip, and up-and-down rod is provided with fixed cover in top end again, and this fixed cover promptly articulates with pole; Pole is provided with cross bar and is provided with hook thereon at the pivot end with up-and-down rod, hook can detain be fixed in the tip and with the pole snapping.

The hand barrow of aforesaid tool armchair structure, its characteristics are: be provided with upper and lower slide cartridge on up-and-down rod, then be installed with slide bar between this two slide cartridge, set firmly a pin axial sleeve that articulates with Chair structure on the slide bar again, it is more firmly smooth-going that chair is moved.

The hand barrow of aforesaid tool armchair structure, its characteristics are: reinforcement frame two ends can be provided with cramp to the basket support side, the fixing location when can be basket support and folding or be the fixing usefulness of carrier.

The utlity model has following advantage:

1. because this case is provided with a pole and up-and-down rod, simultaneously by the continuous action relation between pole and pull bar, pole wheel when folding is folded, then can draw lift and go (occupation mode when being used to transport lighter items) herein, in addition when pole and pull bar join in line, pull bar can be mentioned the drive wheel and open outward, the floor space of whole locomotive body is strengthened to increase the distance between two wheels, but and the bigger or heavier article of load-carrying.

Since this case the juncture between chair and up-and-down rod is handled in the mode of slide bar and two slide cartridges, so, can increase the service life in that slippage when sliding can the ten minutes steady and smooth and be not subject to the application of force improperly and cause the damage of pivoting point.

3. be provided with the reinforcement frame owing to this case, again the intensity of reinforcement up-and-down rod.

4. wheel of the present utility model is for converting formula, and it is a pair of attached generally to have bigger wheel, and the customer can select (please referring to shown in Figure 2) for use according to the purpose of using in advance when going out.
