Abstract
The utility model provides a unidirectional-rotating cam switch positioning mechanism comprising a positioning pedestal, a ratchet wheel, sliding blocks, rolling balls, springs and a rotating shaft. The middle of the ratchet wheel is provided with a shaft hole through which the rotating shaft penetrates; the ratchet wheel is positioned in the positioning pedestal; the upper side surface and the lower side surface of the ratchet wheel are respectively provided one sliding block; one side of each sliding block, which is near to the ratchet wheel, is provided with a semi-circular groove in which one rolling ball is arranged; two springs are arranged between two sides of each sliding block and the lateral side of the positioning pedestal; the peripheral surface of the ratchet wheel is equally provided with four grooves which are perpendicular to each other; one side of each groove is a straight side, and the other side is a circular arc side so that the unidirectional rotation of the rotating shaft can be controlled and positioned at four angles of 90 DEG C; and the angles at the straight sides are set to be able to effectively stop the ratchet wheel from rotating towards the straights sides. The utility model has the advantages that one lateral side of the ratchet wheel is set to be a straight side and the other lateral side is set to be a circular arc side so that the unidirectional rotation of the rotating shaft can be controlled and four rotation points of the ratchet wheel can be controlled.
Description
Technical field
Utility model relates to a kind of detent mechanism of change over switch, relates in particular to a kind of detent mechanism of cam switch, can realize the unidirectional rotation of cam switch and the positioning control on four 90 ° of angles.
Background technology
As depicted in figs. 1 and 2, the recess of the ratchet in the middle of the cam switch originally is a circular shape, ratchet can rotate arbitrarily to both sides like this, easy to operate, such as, cam switch can be done 30 °, 45 °, 60 °, 90 ° clockwise or anticlockwise rotation according to the shape in the positioning pedestal.Under some circuit control situation, need change over switch to do unidirectional rotation, and it is controlled on four anchor points that are mutually 90 °, therefore, be necessary the detent mechanism of the cam switch of a kind of unidirectional rotation newly developed, four point locations.
Summary of the invention
Utility model technical problem to be solved is, mostly is two-way rotation at the detent mechanism of existing cam switch, can't satisfy the needs of unidirectional Spin Control, and the detent mechanism of the cam switch of a kind of unidirectional rotation, four some position controls is provided.
A kind of detent mechanism of cam switch of unidirectional rotation, comprise positioning pedestal, ratchet, slide block, ball, spring and rotating shaft, establish an axis hole in the middle of the ratchet, axis hole is passed in rotating shaft, ratchet places in the positioning pedestal, ratchet two side faces is up and down respectively established a slide block, slide block has a half slot by the ratchet side, put a ball in the half slot, be respectively equipped with two springs between slide block both sides and the positioning pedestal side, the week of ratchet, the same side of groove was a straight flange along evenly being provided with four recesses that are mutually 90 ° of angles on the face, opposite side is the circular arc limit, thereby forms the one-directional rotation control of countershaft and be mutually location on four angles of 90 °.Wherein, the angle of straight flange side is according to circumstances determined, can stop effectively that ratchet is as the criterion to the straight flange sideway swivel.
The circular arc limit of the recess opposite side of described ratchet is 112 °.
Ratchet is inserted the control of rotating shaft wherein, does 360 ° of rotations, when ratchet when circular arc limit one side is rotated, rotating shaft can turn over any angle, still, if when straight flange one sideway swivel, rotating shaft is stopped by ratchet straight flange one side, but can not rotate.In addition, ratchet is provided with four recesses, and become 90 ° of angles between four recesses mutually, ball can't rest on the ledge between the recess, therefore, after the end of operation, ball always is positioned at one of them recess of four recesses of ratchet, ledge that can be between recess has so just been realized the control of four some positions that ratchet is rotated.
The technique effect of utility model is: one, the side of ratchet is set to straight flange on one side, on one side the circular arc limit, realized unidirectional Spin Control; Two, ratchet is provided with four recesses, and 90 ° of angles of four the mutual one-tenth of recesses, realized control to four some positions of ratchet rotation.

Embodiment
As shown in Figure 3 and Figure 4, a kind of detent mechanism of cam switch of unidirectional rotation, comprise positioning pedestal 1, ratchet 5, slide block 2,2 ', ball 3,3 ' spring 4,4 ', 4 ＂, 4 " ' and rotating shaft 6; establish axis holes in the middle of the ratchet 5; axis hole is passed in rotating shaft 6; ratchet 5 places in the positioning pedestal 1; ratchet about in the of 5 two side faces respectively establish a slide block 2; 2 ', slide block 2,2 ' by the ratchet side one half slot is arranged, respectively put a ball 3 in the half slot, 3 ', be respectively equipped with two springs 4 between slide block 2 both sides and positioning pedestal 1 side, 4 ', be respectively equipped with two spring 4 ＂ between slide block 2 ' both sides and positioning pedestal 1 side, 4 " '; the week of described ratchet 5 is along evenly being provided with four recesses 7 that are mutually 90 ° of angles on the face; 7 '; 7 ＂; 7 " ', recess 7,7 ', 7 ＂, 7 " ' the same side is a straight flange 8; opposite side is circular arc limit 9, thereby forms the one-directional rotation control of countershaft 6 and be mutually location on four angles of 90 °.
The recess 7,7 of described ratchet 5 ', " angle [alpha] on the circular arc limit 9 of ' opposite side is 112 ° to 7 ＂, 7.
In the present embodiment, ratchet 5 is inserted the control of rotating shaft 6 wherein, does 360 ° of rotations, and when ratchet 5 rotated to the right, rotating shaft 6 can turn over any angle, and still, if when rotating to the left, rotating shaft 6 is stopped by ratchet 5 straight flanges one side, but can not rotate.In addition, ratchet 5 be provided with four recesses 7,7 ', 7 ＂, 7 " '; and four recesses 7,7 ', 7 ＂, 7 " ' between become 90 ° of angles mutually, ball 3,3 ' can't rest on recess 7,7 ', 7 ＂, 7 " ' between ledge; therefore; after the end of operation; ball 3,3 ' always be positioned at four recesses 7,7 of ratchet 5 ', 7 ＂, 7 " ' one of them recess, can not be positioned at recess 7,7 ', 7 ＂, 7 " ' between ledge, so just realized the control of four some positions that ratchet 5 is rotated.
Certainly, recess 7,7 that also can ratchet 5 ', 7 ＂, 7 " ' the right side be set to straight flange, the left side is set to the circular arc limit, like this, ratchet 5 just can only be done counterclockwise to rotate, and just can only turn left.
