Abstract

The utility model discloses a folding type apparatus with the functions of a handcart, a back frame and a chair. The utility model mainly comprises an n-shaped handle 11, a vehicle main body with an upper support frame 13 and a lower support frame 15, and two groups of couple connecting type meshing components 12, wherein, the upper support frame 13 and the lower support frame 15 present a right angle and are pivoted via a sheathing component 152; a left and a right supporting rods of the lower support frame 15 of the vehicle main body are respectively configured with a group of movable junction type connection resistance components 16 for timely supporting the vehicle main body not to fall down; in addition, the left and the right sides of the point adjacent to a wheel movable component 17 at the lower part of the lower supporting frame 15 of the vehicle main body are configured with a braking assembly 18 and a positioning device 19 which are used for instantly keeping the orientation of the vehicle main body without deviation and without displacement as required. Since the couple connecting type meshing components in the utility model adopt the serration meshing joint sealing transmission, the state of the handle 11 is convenient to adjust, and the interlinked vehicle main body is convenient to convert into the back frame, the chair and the handcart.

Description

The folding type device that integrates handcart, back of the body frame, chair

Technical field

The utility model relates to a kind of folding type device that integrates handcart, back of the body frame, chair.

Background technology

At present, the pattern of go-cart is of a great variety, but generally belongs to fixing structure, does not have collapsible and variability, and function ratio is more single, and the scope of application is wideless.

The utility model content

The purpose of this utility model provides a kind of folding type device that integrates handcart, back of the body frame, chair with multiple function of use.

The utility model includes a handle that is the  font, two body shells that the upper and lower support of tool at right angles articulates via a cover piece installing, two groups of idols connect the formula joggle piece then respectively the spiral shell knot between left and right two and the handle of the upper bracket of body shell, the resistance fitting of two groups of slip-knot formulas, respectively slip-knot is in the left and right end limit of lower carriage, and near the prominent bar that two groups of brake assemblies and locator then are disposed at respectively adjacent wheel moving part and the axostylus axostyle thereof is able to the position that the phase structure is held.

Because it is that transmission is connected airtight in groove engagement that idol connects the formula joggle piece, thereby except the situation of the handle of being convenient to transpose, more convenient interlock body shell; Owing to adopt the slip-knot formula to be connected between each main member, therefore, be convenient to each support upwards lifting or displacement downwards, and lean forward or swing back, thereby can realize that in moment the conversion agent structure is handcart, back of the body frame or chair easily.

The specific embodiment

See also shown in Figure 1, the utility model includes the handle 11 that is the  font, its left side, the right-hand member limit respectively is formed with a hook 112, handle 11 with an antithesis connect formula joggle piece 12 therefrom frame holding the upper bracket 13 of the body shell of containing backrest canvas 131, and via spiral shell knot part 14 regulation and control spiral shell knots, splendid attire 15 of the lower carriages of the body shell of cushion canvas 151 and with upper bracket 13 crossing at right angles with cover piece installing 152, in a left side, right-hand member limit slip-knot respectively one group of resistance fitting 16, dispose one group of brake assemblies 18 in wheel moving part 17 end limits, and via the locator 19 unlikely skew of steady position body shell in time, as shown in Figure 5.

See also shown in Figure 2, idol connects the single-piece 121 of formula joggle piece 12,122 have groove 123,124, be involutory connecting airtight between the two, single-piece 121,122 are groove shape 125 with handle 11 and upper bracket 13 contacted end faces, 126, single-piece 121, a spring 127 is filled at 122 place, axle center, the be arranged so that screw rod 128 and the spiral shell of this spring 127 are tied the perforation 132 of part 14 towards upper bracket 13 and handle 11,133,111 contrapositions connect formula joggle piece 12 jail knot and handle 11 and upper bracket 13 with idol and after being integral, the elastic potential energy of possessing loosening spiral shell knot part 14, revolution idol indirectly connects formula joggle piece 12, each single-piece 121 therebetween, 122 linking attitude position, and then turn handle 11 makes conversion and the use of personal better suited attitude position be its main purpose.

See also shown in Figure 3ly, the idol after clamped connects formula joggle piece 12, and as intending change attitude position therebetween, then only loosening spiral shell knot part 14 can achieve the goal indirectly, simultaneously, because the single-piece of joggle piece is each other for groove connects airtight, so engages the density height, has improved security.

See also shown in Figure 4ly, be connected and the lower carriage 15 of square crossing mutually with cover piece installing 152 with upper bracket 13, in one group of resistance of left and right end face difference slip-knot fitting 16, be convenient to stand still for a long while body shell, the structure of slip-knot formula is more convenient to fold to inner edge surface, makes vehicle body be the horizontal face.Wheel moving part 17 places, below of lower carriage 15 dispose one a group of brake assemblies 18 and a locator 19, brake group 18 has brake pedal 181, see also shown in Figure 4, be linked to lower carriage 15 all-in-one-piece locators 19 behind near the prominent bar 21 the axostylus axostyle 20 that is fastened on brake assemblies 18, with the state of firm more body shell, the locator 19 shown in the figure is the hook formation 22 that is had with itself and hold clamping with prominent bar 21 mutual hooks.

See also shown in Figure 6ly, the handcart behind the bearing load 23 is when intending angle that conversion exerts all one's strength, as long as loosening spiral shell knot part 14 indirect conversion idol therebetween connects the relative engagement orientation of the single-piece 121,122 of formula joggle piece 12 to the required state of handle.

See also shown in Figure 7, schematic diagram when using as back of the body frame for the utility model, to being folded down behind towards the person, 23 horizontal faces by lower carriage 15 of load carry handle 11 by reflexed, support back of the body frame immediately and be linked to the personal shoulder of two braces, 24 collocation of carrying on the back the frame medial surface.

See also shown in Figure 8, decomposing schematic representation when using as chair for the utility model, its lower carriage 15 turns forward down after need upwards being promoted to suitable height again, handle 11 then turns forward to landing, this moment, on the handle of the Big Dipper support 15 flat hooks 112 on the limit, two ends of handle 11, and support land support force and the sane more safety make the lower carriage 15 of cushion can cooperate handle 11 by this.

See also shown in Figure 9, stereogram when being transformed into chair for the utility model, chair with cushion canvas 151 and backrest canvas 131, under the support of handle 11 and upper bracket 13, the other brake assemblies 18 of match wheel moving part, the hook of locating rack 19 are held again, provide one stably situation use safely for people.

See also Figure 10, shown in Figure 11, the utility model is positioned at the support below and disposes a suspender belt 25, and suspender belt 25 is fastened on the upper bracket 13, and the assembly assembly after folding is intact after the configuration via this suspender belt 25, can conveniently be collected and be carried; Wherein Figure 11 shows, the dorsal surface that is positioned at lower carriage is linking two braces 24 especially, and this braces 24 uses during as back of the body frame, as shown in Figure 7.
