Abstract

The utility model belongs to a device manipulation pole handle annex preparation technical field relates to a tangent plane formula handle ball. It is including the cover body, handle bar, nestification, and the cover body is the tangent plane form, is the spherical sleeve part of indent cover tube -shape towards the left side for the left side, and the handle bar is the outside metal round rod end that is frustum of a cone extension form, and nested the handle bar transversely sets up in the internal concave sleeve middle position of cover and top and cover body coupling in order to enclose package in the cutting ferrule spare of handle bar week side, nested set up links firmly in the internal concave sleeve of cover is peripheral, the all side positions of handle bar are put and personally experience sth. Part of the body with the cover in the outside, inboard and handle bar link firmly. The utility model has the characteristics of as follows: the outward appearance is effectual, holds comfortablely and not influenced by the operation direction, is connected safe reliably with the control rod, and the vibration is little during the operation.

Description

A kind of tangent plane formula handle ball

Technical field:

The utility model belongs to device manipulation bar handle attachment manufacture technology field, relates to a kind of tangent plane formula handle ball.

Background technology:

Handle ball is a kind of operating grip annex being installed on device manipulation masthead end, holds comfortable, rapid operation, effect easy to use, be widely used among machinery equipment and fixation means when playing operation.Existing common operation handle attachment, model is more, but the overwhelming majority is gum sleeve member, also has some solid wood sleeve members, and its shape and structure is with cylindric or ellipticity is in the majority.Existing this kind of operating grip annex, the obvious deficiency of existence: is that material is easily aging, adds that anatomical connectivity is scientific and reasonable not, when service time or number of operations acquire a certain degree a little, control stick termination and annex easily loosen and skid, and directly affect operation; Two is hold sense to be subject to direction of operating impact, and in the occasion that environment is narrow, especially when departing from positive oriented manipulation, not only feel is poor for its cylindrical shape or oval operating grip annex, but also feels to require great effort; Three is that wearability is poor, and durable in use not, service life is shorter; Four is profile tradition, and appearance is not ideal, affects equipment class.

Utility model content:

The purpose of this utility model provides a kind of tangent plane formula handle ball for above-mentioned situation.

The technical scheme that the utility model adopts:

A kind of tangent plane formula handle ball, it comprises body, handlebar, nested, body is tangent plane shape on the left of being, is the spherical sleeve member of indent sleeve-shaped towards left side, handlebar is the metal circular rod end head of the outside expansion shape in the frustum of a cone, nested for enclosing the cutting ferrule part being wrapped in handlebar week side, handlebar is horizontally set at body indent sleeve middle position and top is connected with body, nested be arranged at body indent perimeter of sleeve, handlebar week side position and outside and body are connected, inner side and handlebar are connected.

The utility model, described body, is further characterized in that: be inside and outside provided with a convex thick stick circle in middle position at indent sleeve.Described is nested, is further characterized in that: nested outside inside and outside middle position is provided with a concave surface circle, is connected to coincide with the convex thick stick circle of body indent sleeve.

The utility model, described body, adopt bakelite material to make and design with the spherical cover tube structure that left side is tangent plane shape, its object is to: one is that material is tough and tensile, high-low temperature resistant ability is strong, not easily aging; Two is that indent bush structure is comparatively reasonable, contributes to combining closely with nested; Three is hold feel good and do not affect by direction of operating; Four is good looking appearances, with lifting means class.Described is nested, and employing rubber makes and outside is inside and outside provided with the cutting ferrule part profile design of concave surface circle in middle position, its object is to: one is closely can be connected with body indent sleeve, uses effectively to play the embedding making of handlebar in body indent sleeve; Two is have certain elasticity, both can alleviate vibration during operation, handlebar can be avoided again to loosen and skid, to improve stability and the security of equipment operating.

The utility model has following features: appearance is good, holds comfortable and does not affect by direction of operating, and it is reliably safe to be connected with control stick, vibrates little during operation.

Accompanying drawing illustrates:

Fig. 1 is tangent plane formula handle ball structure generalized section, its description of symbols: body 1, handlebar 2, nested 3.

Detailed description of the invention:

Below in conjunction with accompanying drawing, the utility model is described in further detail:

A kind of tangent plane formula handle ball, it comprises body 1, handlebar 2, nested 3, body 1 is tangent plane shape, is the spherical sleeve member of indent sleeve-shaped towards left side for left side, handlebar 2 is the metal circular rod end head of the outside expansion shape in the frustum of a cone, the nested 3 cutting ferrule parts being wrapped in handlebar 2 weeks sides for enclosing, handlebar 2 is horizontally set at body 1 indent sleeve middle position and top is connected with body 1, and nested 3 are arranged at body 1 indent perimeter of sleeve, handlebar 2 weeks side positions and outside and body 1 are connected, inner side and handlebar 2 are connected.
