Description

Light hand tray truck

Technical field

The utility model relates to tray truck, particularly a kind of light hand tray truck.

Background technology

In the time carrying out the carrying that some is placed on the goods on pallet, need traditionally to use the tray trucks such as fork truck to operate.Two kinds of the useful fuel oil of traditional tray truck or battery-driven fork truck and hand fork lifters, the former cost is higher, and the places such as now a lot of supermarkets, warehouse are all used hand fork lifter.The principle of work of conventional manual fork truck is: the pallet fork of fork truck inserts behind pallet inside, and manpower drives hydraulic cylinder works allow pallet fork jacking, departs from after the contacting of ground until pallet, utilizes the goods on roller driving tray and the pallet of pallet fork below to pull, move.This hand fork lifter need to use oil cylinder (or cylinder), with high costs, is prone to fault, needs operator's frequent operation in jacking process, therefore needs now a kind of novel tray transport trolley that can address the above problem.

Summary of the invention

The utility model is in order to solve the existing above-mentioned deficiency of prior art, proposes a kind of simple in structurely, designs ingeniously, easy and simple to handle, utilizes lever principle to realize the light hand tray truck of pallet jacking.

Technical solution of the present utility model is: a kind of light hand tray truck, comprise two symmetrically arranged pallet forks 1, it is characterized in that: the horizontal support 3 that described pallet fork 1 is connected on outside framework 2 by framework 2 and turning set forms, on horizontal support 3, be evenly distributed with four universal BOGEY WHEELs 4, on horizontal support 3, be also evenly distributed with four and enter fork wheel 5, and entering fork wheel 5 can be arc with the transversal surface of ground contact portion, in the time that all universal BOGEY WHEELs 4 are perpendicular to the ground and contact, distance between top and the ground of framework 2 is H, when all enter fork wheel 5 while contacting with ground, distance between top and the ground of framework 2 is h, H > h, be fixedly connected with longitudinal carrier 6 orthogonal with it at the end of horizontal support 3, the top of two longitudinal carriers 6 is all hinged with the bottom of the handle 7 that enters to cup one hand in the other before the chest.

Compared with the existing technology, tool has the following advantages the utility model:

Traditional tray truck, because its jacking apparatus is oil cylinder or cylinder, therefore its holistic cost is difficult to control, and in the time of operation, need user to pull frequently as the handle of lever and drive jacking apparatus, exist complex operation, complicated defect, and oil cylinder or cylinder also easily break down.For the problems referred to above, the application discloses a kind of light hand tray truck of new structure, it has the advantages such as simple in structure, operating process simplification than traditional transport trolley, and it adopts pure physical construction to realize the jacking of pallet, not only Reliability of Microprocessor is higher, but also greatly reduces overall cost, therefore can say that it has possessed multiple advantage, be particularly suitable for applying in the art, its market outlook are very wide.

Fig. 2 is the structural representation of the utility model embodiment state two.

Detailed description of the invention

Below in conjunction with brief description of the drawings detailed description of the invention of the present utility model.As Fig. 1, shown in Fig. 2: a kind of light hand tray truck, comprise two symmetrically arranged pallet forks 1, pallet fork 1 comprises framework 2, be socketed with horizontal support 3 in the external rotating of framework 2, on horizontal support 3, be evenly distributed with four universal BOGEY WHEELs 4, on horizontal support 3, be also evenly distributed with four simultaneously and enter fork wheel 5, when all universal BOGEY WHEELs 4 all perpendicular with ground and while contacting, distance between top (face now directly contacting with pallet) and the ground of framework 2 is H, when all enter fork wheel 5 while all contacting with ground, distance between top (face now directly contacting with pallet) and the ground of framework 2 is h, no matter and the angle that H > h(now enters between fork wheel 5 and ground is how many, H is greater than h) all the time, that is to say, framework 2 contacts and enters fork wheel 5 and contact under this two states and have diff-H with ground under universal BOGEY WHEEL 4 state perpendicular to the ground, be fixedly connected with longitudinal carrier 6 orthogonal with it at the end of horizontal support 3, and the top of two longitudinal carriers 6 is all hinged with the bottom of the handle 7 that enters to cup one hand in the other before the chest, the transversal surface that enters fork wheel 5 parts that can directly contact with ground is arc, like this, entering fork wheel 5 can support transport trolley under state complete and that ground is perpendicular not have, convenient while allowing this kind of transport trolley change between two states, longitudinal carrier 6 also can be pulled to both direction simultaneously, to be adapted to different operational spaces and environment.It should be noted that, although enter fork wheel 5 incomplete and ground perpendicular (in heeling condition) under holding state, but the angle between itself and ground approaches 90 degree, and adding its part contacting with ground is arc, therefore can support smoothly transport trolley completely.

The working process of the light hand tray truck of the utility model embodiment is as follows: in the time that needs use this kind of transport trolley to carry pallet, first allow longitudinal carrier 6 tilt, now enter fork wheel 5 and contact and support transport trolley with ground, promote transport trolley, allow pallet fork 1 enter tray bottom; Then user pulls into the handle 7 of cupping one hand in the other before the chest, drive longitudinal carrier 6 to rotate, longitudinal carrier 6 drives horizontal support 3 to rotate with respect to framework 2, until all universal BOGEY WHEELs 4 contact with ground and perpendicular to the ground, due to H > h, therefore in above-mentioned motion process, the height of framework 2 change (rising), pallet lifting is departed to ground, and user pulls (or promotion) handle 7 that enters to cup one hand in the other before the chest to drive transport trolley, drives the pallet on it together to move; Pallet is transported to behind appointed place, oppositely pull longitudinal carrier 6, allow horizontal support 3 rotate with respect to framework 2 again, allow and again contact with ground into the camber line part of fork wheel 5, the now height of framework 2 change (decline), the pallet ground that falls back, extracts the pallet fork of transport trolley 1 out from tray bottom.

Claims

1. a light hand tray truck, comprise two symmetrically arranged pallet forks (1), it is characterized in that: described pallet fork (1) is connected on the outer horizontal support (3) of framework (2) by framework (2) and turning set and forms, on horizontal support (3), be evenly distributed with four universal BOGEY WHEELs (4), on horizontal support (3), be also evenly distributed with four and enter fork wheel (5), and entering fork wheel (5) can be arc with the transversal surface of ground contact portion, in the time that all universal BOGEY WHEELs (4) are perpendicular to the ground and contact, distance between top and the ground of framework (2) is H, when all enter fork wheel (5) while contacting with ground, distance between top and the ground of framework (2) is h, H > h, be fixedly connected with longitudinal carrier orthogonal with it (6) at the end of horizontal support (3), the top of two longitudinal carriers (6) is all hinged with the bottom of the handle (7) that enters to cup one hand in the other before the chest.
