Abstract
The utility model discloses a novel back carrier matched with handheld machines in use. The novel back carrier at least comprises a back carrier assembly, a supporting cantilever and straps. The back carrier assembly is composed of an upper protection plate, a lower protection plate and a supporting pipe. The supporting cantilever is of a bent shape, the lower portion of the supporting cantilever is vertical, the upper portion of the supporting cantilever extends forwards, a spring balancer is fixed at the upper end of the supporting cantilever in a hanging mode, and the lower end of the supporting cantilever is matched with the supporting pipe in an inserting mode. Double-shoulder type design is adopted in the straps, and the straps are composed of shoulder pads, a waist pad, shoulder straps and a waistband. The novel back carrier is reasonable in structural design and wide in application range; an equipment gravity center is shifted forwards so that stressing on a body is uniform, and burdening feelings are reduced; and the novel back carrier has great significance in lowering labor intensity of workers and improving work efficiency.
Description
Technical field
The utility model relates to the garden maintenance field, relates in particular to a kind of new ideas backrest that is used in conjunction with hand-held machine.
Background technique
In garden maintenance, often use many handheld mechanicals, such as GREEB HEDGE MACHINE, blower, Gao Zhiju, brush cutter etc., because there is not the support of related accessories, direct manual working, the intensity of bringing is very large, easily produces tired in the short time; Simultaneously, the vibrations that produce during the miniature gasoline engine running are also very large, so it is very large to user's arm, shoulder and back harm.In order to alleviate the hand-held weight of user, some mini-plant adopts the design of side-hanging type backrest, such as the brush cutter of present use at present.The backrest that is used for brush cutter is that the fabrics such as ribbon or EVA are sewed into single shoulder or Double-shoulder type backrest, it is only applicable to brush cutter, is positioned at health one side when using owing to brush cutter, and user's health bears a heavy burden uneven, easily produce at short notice fatigue, and easily cause occupational habit-health lateral bending.When adopting present backrest to bear brush cutter, weight of equipment puts on shoulder and the arm fully, and the harm that labor strength and vibrations produce is larger.
The model utility content
For overcoming above-mentioned technical problem, the utility model provides a kind of operator's of making health stressed evenly, and the shaking force when fully absorption equipment is worked slows down workman's health and bears a heavy burden, and reduces the new ideas backrest of workman's sense of fatigue and labor intensity.
For realizing above-mentioned technical purpose, the utility model is realized by the following technical solutions: a kind of new ideas backrest that is used in conjunction with hand-held machine comprises backrest assembly, supporting cantilever, Spring balancer and braces at least; Spring balancer is arranged on the supporting cantilever upper end, and supporting cantilever lower end and the combination of backrest assembly are fixing; Braces is fixedly connected with the backrest assembly.
Described backrest assembly is made of upper guard board, lower backplate and the support tube that is vertically fixed on both rear sides.
Peg graft with support tube and cooperate in described supporting cantilever lower end, splicing position is provided with fixing bolt.
Described upper guard board can be along support tube up-down adjustment position, and is provided with holding down bolt, in order to be applicable to the different operator of the bodily form.
After described supporting cantilever and the combination of backrest assembly, Spring balancer is positioned at operator's positive front upper place; According to the working principle of Spring balancer, at first can hang automatically the handle holding equipment, thereby the weight that the reduction user hands reaches more than 80%.Secondly, the user can be in use, the handheld device free lifting.
Described braces adopts the both shoulders design, comprises at least waistband, shoulder belt, shoulder pad and bustle, and wherein shoulder pad and bustle are fixedly connected with the upper guard board of backrest assembly, lower backplate respectively.
Comfort level when bearing equipment for further increasing, upper guard board and lower backplate adopt the arc design, more meet the physiological characteristic of human body back, waist; The arc radian that supporting cantilever utilizes ergonomics to adopt.
The utlity model has following beneficial effect: during use supporting cantilever is fixedly connected with the backrest assembly, regulate the shoulder pad position according to operator's bodily form, at last garden equipment (brush cutter) is connected on the suspension ring of Spring balancer lower end with a balanced support point, can uses.The utility model is according to the working principle of Spring balancer, creative utilization to Spring balancer, the equipment center of gravity can be transferred to the dead ahead of health, make health stressed evenly, reduce the sense of bearing a heavy burden, sense of fatigue during reduction work, the in addition effect of Spring balancer, fully the power of absorption equipment vibrations generation alleviates the operator and bears a heavy burden, damping vibration reduces vibrations to the injury of human body.It adopts combined type design, and is simple in structure, applied widely, is reducing labor strength, is having remarkable meaning aspect increasing work efficiency.

Embodiment
Shown in accompanying drawing, the backrest assembly is made of lower backplate 1, upper guard board 3 and the support tube 2 that is vertically fixed on both rear sides; Wherein play backplate to be used for limiting and 2 heavy burdens of support support tube, therefore Placement need to be firm; Because for different operators, waist shoulder spacing is different, therefore upper guard board 3 adopts adjustable mode to be connected with support tube 2, can adopts upper guard board 3 rear sides to be provided with the structure of sleeve pipe and holding down bolt 8, but be not limited to this; Supporting cantilever 5 is curved shape, and the bottom is vertical, protract in top, and the upper end hangs and is fixed with Spring balancer 6, and the suspension ring of Spring balancer 6 downsides are used for connection device, pegs graft with support tube 2 and cooperate in supporting cantilever 5 lower ends, and splicing position is provided with fixing bolt 4; It is the bridge of connection device and backrest assembly, and reasonably equipment center is moved to the operator dead ahead; Braces adopts the Double-shoulder type design, is comprised of shoulder pad, bustle, shoulder belt, waistband, and bustle 1 and shoulder pad 10 are individually fixed in the inboard of lower backplate 1 and upper guard board 3, and it has multiple pattern, repeats no more.
The utility model is applicable to all hand-helds, and side-hanging type equipment is not confined to brush cutter.
Based on the utility model theory, there are various ways in backrest, backrest assembly, all belong to the utility model protection domain.
