Abstract

Disclosed is a handle jacket for a hand-held mechanical device, which comprises a hollow tubular body. The wall of the hollow tubular body consists of an inner ring, an outer ring and support reinforcing ribs; wherein the inner ring and the outer ring are both cylindrical structures; the outer ring is sleeved at the periphery of the inner ring; an annular room is left between the outer ring and the inner ring; the support reinforcing ribs are arranged at intervals in the annular room along the circumferential direction; the outer ends of the support reinforcing ribs are connected with the outer ring and the inner ends of the support reinforcing ribs are connected with the inner ring to form an integrally formed hollow tube wall structure. The handle jacket solves the problem that the existing handle jacket has poor vibration absorption effect and an operator feels uncomfortable to hold the handle jacket, which affects work quality and efficiency.

Description

The handle sheath of hand held plant equipment

Technical field

The utility model relates to a kind of hand held plant equipment, relates in particular to a kind of handle sheath of hand held plant equipment.This handle sheath is specially adapted on the handle of hay mover, cutting machine, harvester etc., to improve the comfortableness of operating personnel's hand.

Background technology

At present, the handle of some hand held plant equipment is made by metal or timber, and is the most common in manual equipments such as cutting machine, hay mover, harvester.Directly grasping the equipment handle by operating personnel during operation operates.And in operation process, equipment inevitably can produce vibration, and after the long working, bubble easily in operating personnel's the both hands centre of the palm and lever position, and perhaps perspiring because of operating personnel's palm of the hand makes the handle slippage, thereby delays Job Operations, influences production efficiency.People have invented a kind of handle sheath at the problems referred to above, and as shown in Figure 1, this handle sheath is one by injection molding hollow tubular body, and its tube wall is solid plastic material.This handle sheath is assemblied on the handle of hand held plant equipment the problems referred to above that produced to overcome in the operation process.

Although above-mentioned handle sheath has used for many years, but facts have proved and still have some problems, mainly be because the hand held plant equipment is vibrated bigger at work, this handle sheath is because its tube wall is a solid construction, shock attenuation result is not good, operating personnel are easy to generate the hand discomfort when control hand held plant equipment, influence work quality and production efficiency; Because whole handle sheath adopts injection moulding, manufacturing cost is higher again.

Therefore, the utility model provides a kind of handle sheath of hand held plant equipment, to remedy deficiency of the prior art from improving the prior art angle.

Summary of the invention

The utility model provides a kind of handle sheath of hand held plant equipment, and its purpose mainly is that the existing handle sheath shock attenuation result of solution is not good, causes operating personnel to produce the hand discomfort, influences the problem of work quality and production efficiency.

For achieving the above object, the technical solution adopted in the utility model is: a kind of handle sheath of hand held plant equipment, comprise a hollow tubular body, the tube wall of described hollow tubular body is made up of inner ring, outer ring and supporting rib stiffener, wherein, inner ring and outer ring are tubular structure, the outer ring is set in the inner ring periphery, leave annular space between outer ring and the inner ring, supporting rib stiffener along the circumferential direction is provided with in this annular space at interval, the outboard end of described supporting rib stiffener is connected with the outer ring, and medial extremity is connected with inner ring, forms integrated hollow pipe wall construction with this.

Related content in the technique scheme is explained as follows:

1, in the such scheme, described supporting rib stiffener is at least three, each supporting rib stiffener in annular space along the circumferential direction evenly, at interval and oblique setting.

2, in the such scheme, the inwall of described inner ring is provided with anti-skidding line, this anti-skidding line be used to increase and handle between frictional force, prevent that the handle sheath rotates in operating process.

3, in the such scheme, the outer wall of described outer ring is provided with wave feel line, and this wave feel line integral body becomes striated on the outer wall of outer ring, in order to increase frictional force, prevents that operating personnel are because of palm of the hand perspiration slippage.

4, in the such scheme, described handle sheath adopts elastomeric material to make, and its hardness is in 40～80 scopes.

5, in the such scheme, each cross section perpendicular to axial direction is all identical on the described hollow tubular body.

Because the technique scheme utilization, the utility model compared with prior art has following advantage:

1, because adopting between inner ring and the outer ring, tube wall of the present utility model is hollow-core construction, be connected by many supporting rib stiffeners between inner ring and the outer ring, make it effectively absorb the vibration that equipment is imported into by handle when work, improved the effectiveness in vibration suppression of handle sheath tube wall with this, bring the good comfortableness of holding to operating personnel, thereby improved work quality and production efficiency.

2, because the outer wall of the utility model tube wall outer ring is provided with wave feel line, can improve the coefficient of friction between staff and the handle, increase the degree of holding with a firm grip of hand, thereby prevent that operating personnel from making the problem of handle slippage because of palm of the hand perspiration; Also be provided with anti-skidding line on the inwall of tube wall inner ring, improved and handle between coefficient of friction, thereby avoided slide relative of handle sheath and caused the phenomenon of handle sheath slippage with handle.

3, because the utility model is that tubulose and cross section are even, to extrude back excision forming technology and make so can adopt, processing is simple, cost is lower, is fit to batch process, has improved production efficiency.
