Abstract
An expandable hand-operated carrier fork arm comprises a main arm, expanding arms, equilong rods, damping universal wheels and square sleeves. The equilong rods are hinged to the hinged points of the main arm and the expanding arms, the intersections of the equilong rods are sleeved with the square sleeves, and the damping universal wheels are fixed on the expanding arms. The expandable hand-operated carrier fork arm is simple in structure, the adjustable degree of the stability of a hand-operated carrier is improved, and potential safety hazards can be effectively reduced.
Description
Technical field
The present invention relates to logistics field of mechanical technique, specifically a kind of extendible manual transport trolley yoke.
Background technology
Manual transport trolley is a kind of instrument conventional in current factory floor, in supermarket, in warehouse, is mainly used in carrying freight all kinds or other weights, can reduce labour intensity, raises labour efficiency.Along with the raising of technology, transport trolley load capacity improves thereupon, and the volume of carrying heavy goods or weight are also increasing, and the too urgent center of gravity of goods shakiness that easily causes that fluctuates unexpectedly in handling process or turn is toppled over, thus the potential safety hazard of causing.
Summary of the invention
The object of patent of the present invention is just to provide a kind of extendible manual transport trolley yoke, by the mode of contractile extensible arm is installed in yoke both sides, reaches the object that improves manual transport trolley stability.
The present invention solves the problems referred to above by the following technical solutions: a kind of extendible manual transport trolley yoke, comprise principal arm, extensible arm, etc. stock, damping universal wheels and square sleeve, the described stock that waits is articulated with on the hinge-point on principal arm and extensible arm, square sleeve is enclosed within etc. on the point of crossing of stock, and damping universal wheels is fixed on extensible arm.
Described square sleeve aspect ratio is earthward 1.73:1.
Described extensible arm is two.
The described stock that waits is eight, and hinge-point is eight, is connected on eight hinge-points of principal arm and extensible arm after waiting stock hinged between two.
Described damping universal wheels is four.
Described square sleeve is four.
Outstanding advantages of the present invention is:
1, can, according to the divergence of the different adjustment extensible arm of the size carrying cargo, quality, maintain best stability.
2, extensible arm is collapsible, and the use in little space is surveyed in the moving carrying of might as well being in the way.
Accompanying drawing explanation
Fig. 1 is extendible manual transport trolley yoke structural representation of the present invention.
Fig. 2 is that the A of extendible manual transport trolley yoke of the present invention is to view.
Fig. 3 is the square sleeve lateral plan of extendible manual transport trolley yoke of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is further described.
As Fig. 1, shown in Fig. 2 and Fig. 3, extendible manual transport trolley yoke of the present invention, comprise principal arm 8, the first extensible arm 27, the second extensible arm 16, the first stock such as grade 3, the second stock such as grade 5, C grade stock 11, fourth class stock 14, the 5th stock such as grade 17, the 6th stock such as grade 20, the 7th stock such as grade 23, the 8th stock such as grade 25, the first damping universal wheels 1, the second damping universal wheels 13, the 3rd damping universal wheels 19, the 4th damping universal wheels 24, the first square sleeve 4, the second square sleeve 7, third party's shape cover 10, square cover 12, the first hinge-point 2, the second hinge-point 6, the 3rd hinge-point 9, the 4th hinge-point 15, the 5th hinge-point 18, the 6th hinge-point 21, the 7th hinge-point 22, the 8th hinge-point 26.
As shown in Figure 1, by on the hinge-point on the first stock such as grade 3, the stock 5 such as second, C grade stock 11, fourth class stock 14, the stock 17 such as the 5th, the stock 20 such as the 6th, the stock 23 such as the 7th, the stock 25 hinged rear connection between two such as the 8th and principal arm 8 and the first extensible arm 27 and the second extensible arm 16, and the first square sleeve 4, the second square sleeve 7, third party's shape cover 10, square cover 12 are enclosed within on the point of crossing of every pair of articulated bracket as shown in Figure 1.Thereby reach the object that makes the first extensible arm 27 and the second extensible arm 16 free-extensions regulate stability.
