Abstract

The utility model discloses a multifunctional folding carrier for repairing under chassis, which comprises a carrier frame of which the bottom is provided with a carrier wheel, and a back cushion arranged on the carrier frame, wherein, the carrier frame is composed of cross beams and longitudinal beams, and the cross beams and the longitudinal beams form a moon shape. The joint of the front longitudinal beam and the back longitudinal beam is in a hinge mode, the joints of the longitudinal beams and the cross beams are in movable connecting modes, and joints from two to four of the joints are in dismountable connecting modes. The back part of the carrier frame is provided with a movable support which can be lifted, and the front part of the carrier frame is provided with an operating part for adjusting the support and a positioning device. The length of the rope of the operating part connected with the movable support is equal. The utility model has the advantages of arbitrary move and height adjustment, and convenient use. The utility model is disassembled and assembled without any tools. The utility model can also be used as a small towing carrier, a chair, etc.

Description

Maintenance folds multiservice car at the bottom of the car

The utility model relates to a kind of automobile bottom maintenance apparatus.

Automobile bottom is out of order, and the driver need pierce the chassis maintenance of going down.Especially road repair, a shield commonly used is layered on the ground, and the people faces upward its enterprising line operate of lying, and because of shield is little, and can not move, and is when repairing the different parts fault, very inconvenient.Particularly hot day, the people was scalded on the road surface, the easily wet again stolen goods clothing in sleet sky.

The purpose of this utility model is to provide a kind of maintenance apparatus at the bottom of the car that folds, uses very easily.

The major technique content is: maintenance folds multiservice car at the bottom of a kind of car, comprises wheel-mounted vehicle frame in bottom and the back pad that is placed on the vehicle frame.Vehicle frame is made of crossbeam and longeron and is " moon " font, and for ease of folding, longeron divides two sections, middle hinge joint, crossbeam adopts movable the connection with the longeron intersection, install and remove fold very convenient.For ease of regulating maintenance personal's head, shoulder height, the vehicle frame rear portion is provided with movable supporting, and the vehicle frame front portion is provided with regulates the operating parts that supports, and the cable of operating parts cover end links to each other with movable supporting by behind the keeper, and it is stressed even that length of warping winch equates, operating parts is by claw plate and ratchet fastening position.Discharge claw plate, can reduce bearing height.

The more original technology of the utility model has the following advantages: 1. vehicle frame is taken down the exhibits does not need any instrument, installs folding very convenient; 2. supporting elevation freely, good stability; 3. one-object-many-purposes promptly can be used for repairing, and also can make loading trailer or seat etc.

Accompanying drawing provides an embodiment of the present utility model.

Fig. 1 is the utility model master TV structure schematic diagram;

Fig. 2 is the utility model plan structure schematic diagram;

Fig. 3 looks schematic diagram for the operating parts master;

Fig. 4 is the operating parts schematic top plan view.

See also Fig. 1,2, this multiservice car is made up of vehicle frame, wheel 15, back pad 7 etc., and wheel 15 adopts universal wheels or directional wheel to be installed on bottom of frame, and vehicle frame is made of 5,10,16 and 4 longerons 6,11 of 3 crossbeams and is " moon " font.There is outrigger 2 at the vehicle frame rear portion, front longitudinal 6 and 9 hinge joints of floor side member 11 usefulness hinge class formations, flexible connection is all adopted in longeron, outrigger and crossbeam junction, and wherein the 2-4 place is that bolt-type or cross-latch type connector 20 connect, be convenient to tear open and take off, other junctions adopt bolt 19 or horizontal tying to connect (see figure 2).Bolt 19 heads are fixed on the beam, and screw rod screws on nut after passing longeron and crossbeam again, and nut is braked.Bolt-type connector 20 is promptly fixed the short pin of a strap bolt in beam end, beam-end is opened φ shape hole, rotates an angle behind the short pin insertion φ shape hole and promptly firmly tacks.This mode is taken apart, folds very convenient.Back pad 7 should be with the collapsible bamboo curtain splint that maybe can circumnutate, and back pad length is longer than multiservice car length.

The movable supporting 4 of 2 belt wheels 1 is equipped with at the vehicle frame rear portion.Two of rear cross beam 5 has cable clamp 3, two supports 4 to be connected on two supporting seats 22 that are placed under the rear cross beam 5 by axle 21, has 2 springs 23 to fasten feet on the axle 21.Cable keeper 17 is equipped with at front beam 16 or middle cross beam 10 middle parts, makes cable 8 arrive two equal in length that support, and stressed even.The operating parts 14 that 4 liftings are supported in operation is equipped with in front beam 16 1 end bottoms, and operating parts is by claw plate 12 ratchet cards 13 location on next door, the cable clamp 3 that cable 8 flexibly connects on support 4 and the operating sleeve 18.The cable knot is arranged on the cable 8.Cable clamp 3, keeper 17 are arc with the contact position of cable 8, can reduce friction, and prolong the cable life-span.

One arc ratchet card 13 and claw plate 12 couplings are arranged on the operating parts 14, and the ratchet card is other a circular hole, is with shaft-like clutch 24 in the hole, and is connected handle 26 sides of operating parts 14 with briquetting 25.The clutch of shaft-like clutch 24 control claw plates 12 and ratchet card 13.

When operating parts 14 was pulled, cable 8 affected and supports 4, and the vehicle frame rear portion raises, and the tooth on the claw plate 12 blocks ratchet card 13, made the operating parts location.Pulling handle 26 again, continues to raise in the vehicle frame rear portion.When need reducing vehicle frame, press dynamic clutch 24, tooth plate 12 breaks away from tooth card 13, moves the reduction of vehicle frame rear portion after being supported under spring 23 or the effect of body weight for humans power.Be reduced to certain angle, loosen the clutch 24, operating parts 14 is fixed again.

Cable is inserted in the cable clamp 3 of rear cross beam 5, can makes trailer and seat and use.
