Abstract
The utility model relates to an antifriction valve spool driving lever, which comprises a lever rod and a head positioned at one end of the lever body, wherein the lever body is provided with a through hole, and the head in a square structure is provided with a plurality of circular holes communicated with the through hole. The head of the antifriction valve spool driving lever is in the square structure, so that the contact area of the head and a driving plate is decreased, friction force between the head and the driving plate is reduced, and hand feeling in rotation of the valve spool driving lever is improved.
Description
[technical field]
The utility model relates to a kind of constituent elements of spool, is specifically related to a kind of friction resistant spool driving lever, belongs to valve technology field.
[background technique]
The spool driving lever of prior art has a head usually, this nose shape structure spherical in shape.When described head and the cooperation of dial hole, both area of contact are bigger, thereby make the big and wearing and tearing easily of frictional force.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of structure improved friction resistant spool driving lever that has, to overcome described defective of the prior art.
[model utility content]
For addressing the above problem, the purpose of this utility model is to provide the friction resistant spool driving lever that a kind of surface friction drag is little, rotate good hand touch.
For achieving the above object, the technological scheme that the utility model is taked is: a kind of friction resistant spool driving lever, the head that it comprises rod body part and is positioned at rod body part one end; Wherein, described rod body part is provided with a through hole; The described head structure that is square is provided with some circular holes that are communicated with through hole in this head.
Friction resistant spool driving lever of the present utility model further is set to: described rod body part and head are integral structure.
Compared with prior art, the utlity model has following beneficial effect: friction resistant spool driving lever of the present utility model is by being arranged to square structure with head, thereby reduced the area of contact of head and dial, reduced frictional force between the two, the feel when having improved the rotation of spool driving lever.
[description of drawings]
Fig. 1 is the stereogram of friction resistant spool driving lever of the present utility model and dial.
[embodiment]
See also shown in the Figure of description 1, the utility model is a kind of friction resistant spool driving lever, it can cooperate with a dial 9 with a dial hole 91, the head 2 that it comprises rod body part 1 and is positioned at rod body part 1 one ends, and described rod body part 1 and head 2 are integral structure.Described rod body part 1 is provided with a through hole 11.
The greatest improvement part of friction resistant spool driving lever of the present utility model is: described head 2 structure that is square is provided with some circular holes 21 that are communicated with through hole 11 in this head 2.
Friction resistant spool driving lever of the present utility model is by being arranged to square structure with head 2, thereby reduced the area of contact in the dial hole 91 of head 2 and dial 9, reduced frictional force between the two, the feel when having improved this spool driving lever rotation.
Above embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within made any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
Claims (2)
1. a friction resistant spool driving lever is characterized in that: the head that comprises rod body part and be positioned at rod body part one end; Wherein, described rod body part is provided with a through hole; The described head structure that is square is provided with some circular holes that are communicated with through hole in this head.
2. friction resistant spool driving lever as claimed in claim 1 is characterized in that: described rod body part and head are integral structure.
