Abstract
The utility model discloses an intermediate reserved protection board, which is integrally symmetric about a central line, and the intermediate reserved protection board comprises an upper needle moving surface and a lower needle moving surface; the upper needle moving surface comprises a first plane, a first oblique surface and a second oblique surface; the first plane, the first oblique surface and the second oblique surface are sequentially connected with one another through an arc surface; the lower needle moving surface comprises a third oblique surface, a fourth oblique surface and a second plane; the third oblique surface, the fourth oblique surface and the second plane are sequentially transitioned through an arc surface; and the second oblique surface is connected with the third oblique surface through an acute transitional way. The intermediate reserved protection board has the beneficial effects that the friction between a knitting needle and the needle moving surface is reduced; and moreover, the knitting needle is easier for entering the needle moving surface.
Description
Technical field
The utility model belongs to technical field of knitting machinery, and particularly middle the reservation protected the mountain.
Background technology
The playback of at present flat machine braiding process spring needle relies on guide pin triangular and the clear pin triangle movable up and down acting in conjunction that is fixed on the motherboard of angle, mountain, this structure needs about connecting rod commutation to reach the up and down of pin triangle clearly, because the more complicated of linkage own, in addition, add the factors such as greasy dirt, hair ash, clear pin triangle is stuck easily in reciprocating motion, the faults such as striker occur, affects the operating efficiency of machine and user's economic benefit.
Summary of the invention
The purpose of this utility model is in order to address the above problem, to provide a kind of middle reservation simple in structure to protect the mountain.
For this reason, the technical solution of the utility model is: the middle reservation, protected the mountain, and whole one-tenth center line is symmetrical, and it is characterized in that: it comprises walks dial and walk dial once on one; The face of taking the needle comprises the first plane, the first inclined-plane and the second inclined-plane on described; Described the first plane, the first inclined-plane and be connected the inclined-plane and connect by the arc surface transition successively; The face of taking the needle comprises the 3rd inclined-plane, the 4th inclined-plane and the second plane under described; Described the 3rd inclined-plane, the 4th inclined-plane and be connected the plane and connect by the arc surface transition successively; Described the second inclined-plane connects by the acute angle transition with the 3rd inclined-plane.
Say that further the angle on described the second inclined-plane and the first plane is greater than the angle on the first inclined-plane and the first plane.
Say that further the angle on described the 4th inclined-plane and the second plane is greater than the angle on the 3rd inclined-plane and the second plane.
The utility model is distributed in three places, left, center, right of triangle motherboard, knitting needle can by on walk dial and lower walk dial and take the needle, each face connects by the arc surface transition successively, so that knitting needle and the friction minimizing of walking dial.And the angle on the second inclined-plane and the first plane is greater than the angle on the first inclined-plane and the 4th inclined-plane and the second plane angle greater than the 3rd inclined-plane and the second plane, so that knitting needle is more prone to enter away dial.
Description of drawings
Be described in further details below in conjunction with accompanying drawing and embodiment of the present utility model.
Fig. 1 is the utility model scheme of installation;
Fig. 2 is structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing.Keep in the middle of the present embodiment and protect three places, left, center, right that mountain 2 is distributed in triangle motherboard 1, its whole one-tenth center line is symmetrical, comprises and walks dial on one and walk dial once.On the face of taking the needle comprise the first plane 21, the first inclined-plane 22 and the second inclined-plane 23; The first plane 21, the first inclined-plane 22 and be connected inclined-plane 23 and connect by the arc surface transition successively.Under the face of taking the needle comprise the 3rd inclined-plane 24, the 4th inclined-plane 25 and the second plane 26; The 3rd inclined-plane 24, the 4th inclined-plane 25 and be connected plane 26 and connect by the arc surface transition successively.The second inclined-plane 23 connects by the acute angle transition with the 3rd inclined-plane 24.The included angle B on the second inclined-plane 23 and the first plane 21 is greater than the included angle A on the first inclined-plane 22 and the first plane 21, and the angle D on the 4th inclined-plane and the second plane is greater than the angle C on the 3rd inclined-plane and the second plane.
Claims (3)
1. middle the reservation, protected the mountain, and whole one-tenth center line is symmetrical, and it is characterized in that: it comprises walks dial and walk dial once on one; The face of taking the needle comprises the first plane, the first inclined-plane and the second inclined-plane on described; Described the first plane, the first inclined-plane and be connected the inclined-plane and connect by the arc surface transition successively; The face of taking the needle comprises the 3rd inclined-plane, the 4th inclined-plane and the second plane under described; Described the 3rd inclined-plane, the 4th inclined-plane and be connected the plane and connect by the arc surface transition successively; Described the second inclined-plane connects by the acute angle transition with the 3rd inclined-plane.
