Abstract

The utility model relates to an unloosen universal bending pipe with better bending ability. The utility model is composed of a plurality of unit bodies which are in sleeve joints and are linked together; the head of each unit body is in an arc shape and the inside of each unit body is in a hollow shape; the front end of the head of each unit body is especially provided with a baffling point face, and a baffling stop face is prearranged on the inner wall of the sleeve joint of another unit body; the baffling point face is baffled with the baffling stop face to block the continue bending. Even when the utility model is subjected to strong twisting force, the head of the unit body can not be disengaged from the sleeve joint of another unit body, which can maintain the completeness of the structure to enhance the use value of the utility model.

Description

The universal curved tube that do not come off that bending degree is better

The better universal curved tube that do not come off of a kind of bending degree that relates to of the present utility model, it is linked by several cell cube sockets, all do not cause the head of cell cube to break away from the belled part of another cell cube even impose again big torsion, and be maintained the integrity of its structure.

The universal curved tube of commonly using has the advantages that arbitrarily to bend, it can apply on the various working substances or other products that must rotate flexibly, as shown in Figure 1, its structure composition is mainly linked by several cell cube sockets, its each cell cube all comprises a head 11 and a belled part 12, in between the two being thin narrow neck 13, this head 11 has the sphere of circular arc, belled part 12 then has the interior circular arc containing space that also can rotate arbitrarily for head 11 sockets, constitute the universal curved tube 10 of deflection by the headtotail of each cell cube, utilize the head 11 of each cell cube and cooperating of belled part 12, can change turning to of universal curved tube 10 according to need arbitrarily, extend according to this and applied to each side, doll as shown in Figure 2, be about to the universal curved tube 10 of this kind and apply to hand, shank, even on the health, its arm and shank can be rotated flexibly, and health can be done pitching or lateral bending action, it is vivid that the body that makes a tool have no life is able to, with human exercises, attitude is imitated life-likely, significantly improves to be worth.

Yet with regard to the universal curved tube of commonly using 10, structural design is to the greatest extent imperfect, make it produce serious disappearance when changeing in scratching, promptly the head 11 because of its cell cube is not a complete sphere, but cut flat the processing in the first half, though unlikelyly influence the function that it scratches commentaries on classics, yet when it scratches a certain degree (nearly approximately 90 degree of adjacent two cell cubes) that goes to, because of there is no, this belled part stops head 11 appropriate configuration outward, promptly easily cause the head 11 of cell cube to break away from the belled part 12 of another cell cube if continue to impose excessive torsion this moment, and it is divided into two, destroy integrally-built integrity, lose the function that its flexible changes.

In view of this, the universal curved tube that do not come off that provides a kind of bending degree better is provided the purpose of this utility model, by its structural design, even make universal curved tube under the situation of big torsion, all not cause the head of cell cube to break away from the belled part of another cell cube, to keep the integrity of its structure.

The better universal curved tube that do not come off of bending degree that provides according to the utility model, it is linked by several cell cube sockets, the head of each cell cube is circular-arc, inside is hollow shape, stopping surface default on the point-supporting surface of the ad hoc micro-tilted angle of head front end and the belled part inwall of another cell cube touches whetstone mutually, can stop it to continue bending fully, all not cause the head of cell cube to break away from the belled part of another cell cube even impose again big torsion, and be maintained the integrity of its structure.

For making the relevant personnel can at length understand structure of the present utility model, feature and other purposes, be equipped with now that accompanying drawing describes in detail as after.

Fig. 1 is a combination schematic representation of commonly using universal curved tube.

Fig. 2 commonly uses the enforcement illustration that universal curved tube applies to doll.

Fig. 3 is the schematic representation of the cell cube of the universal curved tube of the utility model.

Action schematic representation when Fig. 4 scratches commentaries on classics for the universal curved tube of the utility model.

Fig. 5 is the schematic representation of the combination of the universal curved tube of the utility model.

Shown in please the Fig. 3 to 5 of ginseng portion, the universal curved tube 30 of the utility model is linked by several cell cube sockets, each cell cube respectively has head 31, belled part 32, the point-supporting surface 34 of neck 33 and head 31 front ends, cut the particular design of staying hollow shape 36 in flat-shaped, the inside of cell cube have inwall 35 and engagement head 31 point-supporting surface 34 ad hoc stopping surface 37, in order to touching whetstone mutually, in the time of can effectively stoping the use universal curved tube 30 that cell cube linked to do bending action, the head 30 of its cell cube detaches the belled part 32 of another cell cube, because of the head 31 front end spies of cell cube in this structure are designed to a micro-tilted angle, be referred to as point-supporting surface 34, the inwall 35 set spaces of this head 31 and point-supporting surface 34 and the belled part 32 of another cell cube almost become to contact shape fully, driving fit very, make the head 31 of cell cube in the inwall 35 of another cell cube, scratch when forwarding a certain degree to, the point-supporting surface 34 of the head 31 front end slightly-inclineds of cell cube touches whetstone fully with the stopping surface 37 that the inwall of the belled part 32 of another cell cube 35 is provided with, and this moment cell cube neck 33 also bent hinder marginal part near the belled part 32 of another cell cube, as shown in Figure 4, two cell cubes will be touched whetstone fully this moment, all can't allow its separation in the belled part 32 of the head 31 of cell cube or another cell cube even impose bigger strength again, again the leading edge of the point-supporting surface 34 of head 31 front ends of cell cube is done all flat processing, make it to become hollow shape 36, inner headspace when this hollow shape 36 can make several cell cube serial connections, electric wire is passed through in the space thus, cord etc.

In sum, the universal curved tube that do not come off that the utility model bending degree is better is the innovation structure of simplifying, and reaches more economic purpose.

Claims

The universal curved tube that do not come off that a kind of bending degree is better, it is linked by several cell cube sockets, it is characterized in that: the head of each cell cube is one circular-arc, inside is hollow shape, stopping surface default on the point-supporting surface of the ad hoc micro-tilted angle of head front end and the belled part inwall of another cell cube touches whetstone mutually, imposes the structure that head that big torsion all do not cause cell cube breaks away from the belled part of another cell cube even form again.
