Abstract
The invention provides a positioning adjusting mechanism based on a ratchet and a ratchet wheel. The positioning adjusting mechanism comprises a base and a component to be adjusted, which are connected through a reversing structure; the ratchet wheel is connected to the component to be adjusted through a rotating shaft, and the other end of the ratchet wheel faces the base; the ratchet of which the size corresponds to a ratchet wheel groove in the ratchet wheel is connected to the base through a reset spring. A release groove is formed in the ratchet wheel, when the base and the component to be adjusted are jointed, the ratchet is positioned in the release groove; when the component does not need to be adjusted, the pressure of the reset spring is released, so that the service life of the reset spring is prolonged. According to the positioning adjusting mechanism disclosed by the invention, positioning adjusting is performed based on the ratchet and the ratchet wheel, so that the positioning is accurate and the use is convenient.
Description
Technical field
The present invention relates to mechanical structure field, specifically a kind of positioning regulating mechanism based on ratchet ratchet.
Background technique
Need the device of rotation at some, in such as seat or door and window, need to position pivotal position.The regulating positioning device of present use uses punch card button to position usually, and positioning precision is poor, uses inconvenience.
Summary of the invention
The present invention, in order to solve the problem of prior art, provides a kind of positioning regulating mechanism based on ratchet ratchet, accurate positioning, easy to use.
The present invention includes the pedestal and parts to be regulated that are connected by overturn structure, described parts to be regulated are connected with ratchet by rotating shaft, and the ratchet the other end is towards pedestal; Described pedestal is connected with the ratchet corresponding with ratchet slot size on ratchet by Returnning spring.
Further improvement, described ratchet has release groove, and when pedestal and parts to be regulated laminating, ratchet is positioned at release groove, discharging the pressure of Returnning spring, extending the working life of Returnning spring when not needing adjustment member.
Beneficial effect of the present invention is: position adjustment based on ratchet ratchet, accurate positioning, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 (a) (b) (c) (d) is working procedure schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, comprise the pedestal 1 and parts to be regulated 2 that are connected by overturn structure, described parts to be regulated 2 are connected with ratchet 3 by rotating shaft 6, ratchet 3 the other end is towards pedestal 1 for structure of the present invention; Described pedestal 1 is connected with the ratchet 4 corresponding with ratchet slot size on ratchet 3 by Returnning spring 5.
Described ratchet 3 has release groove, and when pedestal 1 and parts to be regulated 2 are fitted, ratchet 4 is positioned at release groove.Discharging the pressure of Returnning spring when not needing adjustment member, extending the working life of Returnning spring.
Working procedure of the present invention is as shown in Figure 2:
1, movable part is from minimum point, and ratchet is positioned at release groove, as Fig. 2 (a).
2, when activity moves up, ratchet reverses teeth directional in release groove, and loose one's grip in arbitrary position, ratchet, under the pulling force effect of spring, makes ratchet locking in nearest ratchet slot, as Fig. 2 (b);
3, movable part is when any locked position needs to unlock, and mobile movable part is to peak, and the release groove that ratchet slips into ratchet is interior as Fig. 2 (c).
4, ratchet reverses teeth directional in the release groove of ratchet, unlocks successfully, now can move to minimum point, as Fig. 2 (d).
Embody rule approach of the present invention is a lot, and the above is only the preferred embodiment of the present invention, should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvement, these improvement also should be considered as protection scope of the present invention.
