The hanging plate is provided with a hook for holding articles.
The utility model has the advantages that:
the utility model discloses a carry thing laborsaving device, overall structure is simple, easy dismounting, and is small, light in weight, portable, the bearing belt is fixed on the waist or is taken on one's shoulder, article pass through the assembly pulley that the lifting rope walked around movable pulley and fixed pulley and constitute, lifting rope one end is fixed on the bearing belt, the other end is fixed and is carried on one's hand, the lifting rope is divided into several sections through the assembly pulley, let the waist of health, shoulder and hand and arm share the gravity of article jointly, let the pulling force of hand diminish, it is wide to be suitable for the crowd, especially, carry the thing for old person and the not enough crowd of strength provides convenience.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural view of the pulley labor-saving mechanism of the present invention.
Detailed Description
The following further describes the embodiments of the present invention with reference to the drawings.
As shown in figures 1 and 2, the labor-saving device for carrying articles of the utility model is characterized in that the labor-saving device comprises a bearing belt 8, a pulley labor-saving mechanism arranged on the bearing belt 8, the pulley labor-saving mechanism comprises a bearing belt hanging plate 5 arranged on the bearing belt 8, a pulley frame 4 arranged on the bearing belt hanging plate 5, a pulley block fixed on the pulley frame 4, a hand handle 1 connected with the pulley block, an article hanging plate 7 connected with the pulley block,
the pulley block comprises N fixed pulleys 3, N +1 movable pulleys 6 and a lifting rope 2 for connecting the N fixed pulleys 3 and the N +1 movable pulleys 6, one end of the lifting rope 2 is connected with the handle 1, the other end is connected with the bearing belt hanging plate 5,
the N +1 movable pulleys 6 are connected with the hanging plate 7.
The pulley labor-saving mechanism is one pair or two pairs. When the bearing belt 8 is used as a waist belt, one pair or two pairs of pulley labor-saving mechanisms can be arranged, and the two pairs of pulley labor-saving mechanisms can simultaneously save labor for left and right hands. When the bearing belt 8 is used as a shoulder belt, a pair of pulley labor-saving mechanisms or two pulley labor-saving mechanisms can be arranged, and when the two shoulders are respectively provided with a pair of pulley labor-saving mechanisms, the left hand and the right hand can save labor at the same time. N of the N fixed pulleys is more than or equal to 0. The value of N can take 0, only 1 movable pulley at this moment, the one end of lifting rope with handle be connected, the other end with the bearing area link plate be connected, laborsaving about 1/2. The more the number of the movable pulleys 6 is, the more labor is saved.
The hanging plate 7 is provided with a hook for holding articles. The carrying object can be directly hung on the object bearing hook.
The utility model discloses a carry thing laborsaving device, including pulley yoke 4, fixed pulley 3, movable pulley 6, lifting rope 2, bearing belt link plate 5, hang thing board 7, bearing belt 8, hand handle 1 etc. fix bearing belt 8 on the waist or shoulder, walk around the assembly pulley that movable pulley 6 and fixed pulley 3 constitute through lifting rope 2, 2 one ends of lifting rope are fixed on bearing belt link plate 5, and the other end is fixed on hand handle 1, falls into several sections with lifting rope 2 through the assembly pulley, is pulling jointly and is being used for hanging the thing board 7 of hanging of carrying article.
When the article is static, the sum of upward tension of the lifting ropes 2 is equal to the gravity of the article in the gravity direction, so that the tension (equal to the tension of the hand) of the article when the handle 1 is used for pulling a rope is about 1/m (m is the number of the sections of the lifting ropes 2 used for pulling the article) of the gravity of the article, and considering that the gravity which can be borne by the waist and the shoulders is larger than that of the hand and the arms and is more durable, the rest (m-1)/m gravity of the article is borne by the waist or the shoulders or both of the waist and the shoulders, and one special case is that when the handle is hung on the waist, the gravity of the article is borne by the waist and the shoulders, the hand can be released temporarily, so that the tension of the hand and the arms is reduced when the article is lifted, and the article is lifted more easily.
As shown in fig. 2, in order to distribute the lifting rope 2, the movable pulley 6 and the fixed pulley 3 when a pair of pulley blocks is used, the lifting rope 2 is divided into four sections, namely 1/4 for bearing the weight of the article by hand and 3/4 for bearing the weight of the article by waist and shoulder. According to the labor-saving principle of the movable pulley, the lifting rope bypasses the pulley block, one section of the lifting rope 2 is pulled by hand, m sections of the lifting rope 2 can simultaneously pull the object, the pulling force of each section of the lifting rope 2 is about 1/m of the gravity of the object, when only one section of the lifting rope 2 is lifted by a hand, the pulling force of the hand is about 1/m of the gravity of the object, and the rest (m-1)/m of the gravity of the object can bear the waist or the shoulders of the body or the waist or the shoulders of the body together. And so on.
The utility model discloses the material of each spare part is preferred to be selected for use the rubber or the plastics material that density is little among the macromolecular material, light in weight, portable, toughness is good.
The utility model discloses a carry thing laborsaving device, overall structure is simple, easy dismounting, and is small, light in weight, portable, the bearing belt is fixed on the waist or is taken on one's shoulder, article pass through the assembly pulley that the lifting rope walked around movable pulley and fixed pulley and constitute, lifting rope one end is fixed on bearing belt link plate 5, the other end is fixed on hand handle 1, lifting rope 2 is divided into several sections through the assembly pulley, let the waist of health, shoulder and hand and arm share the gravity of article jointly, let the pulling force of hand diminish, it is wide to be suitable for the crowd, especially, it provides convenience to carry the thing for old person and the not enough crowd of strength.
