Abstract
The utility model discloses a separating and meshing type ratchet rotating shaft which is characterized by being provided with two ratchets, wherein the two ratchets in mutual mesh can be separated, one ratchet is a fixed ratchet, and the other ratchet is a movable ratchet. The separating and meshing type ratchet rotating shaft can be used under the condition that a rotating shaft needs to bear larger torsion when folding furniture and the like stay in a set rotating shaft angle.
Description
Technical field
The present invention relates to a kind of rotating shaft, particularly a kind of can load separating-closing type ratchet rotating shaft of big torsion of rotating shaft tie point when closed.
Background technique
Be used for the axle that rotation work bears moment of torsion and be called rotating shaft.
At present known have angle limits rotating shaft, multistage torque rotary shaft, fixed point rotating shaft or freely stop rotating shaft and can stop in the rotating shaft angle of setting, but its structure is difficult to bear bigger torsion.
Summary of the invention
In order to solve the above problems, the invention provides a kind of can in the rotating shaft angle of setting, the stop, the rotating shaft tie point can be loaded than the separating-closing type ratchet rotating shaft of big torsion when closed.
The present invention's technological scheme that is adopted of dealing with problems is such:
The rotating shaft of a kind of separating-closing type ratchet is characterized in that:
The rotating shaft of separating-closing type ratchet is provided with the ratchet of two mutual interlocks that can separate, and it is fixed ratchet wheel that one of them ratchet is set, and a ratchet is movable ratchet;
The hook tooth of described mutual interlock ratchet is arranged on ratchet circumference or ratchet disk;
Described fixed ratchet wheel is fixedly connected with the rotating shaft of concentric, movable ratchet activity is set is rotatably connected in rotating shaft;
Described rotating shaft is known non-angular restriction rotating shaft, angle limits rotating shaft, multistage torque rotary shaft, fixed point rotating shaft is arranged or freely stop rotating shaft;
Be provided with spring groove at fixed ratchet wheel, in spring groove, be provided with spring;
Length after the described length of spring compressed is less than or equal to the degree of depth of spring groove, and the length after relaxing of spring resets is greater than the length of hook tooth and the degree of depth sum of spring groove;
Described hook tooth is the overall fixed structure, perhaps is provided with reed in the end of hook tooth;
Described reed is fixedly connected on the hook tooth end, or movable telescopic is attached at hook tooth inside, ejects in the hook tooth end by a Telescopic spring;
When the end of hook tooth was provided with reed, the length after relaxing of spring resets should be greater than the length of hook tooth standing part and the degree of depth sum of spring groove, and less than the degree of depth sum of hook tooth total length and spring groove;
At an end of separating-closing type ratchet rotating shaft, the arranged outside of movable ratchet has ratchet deciliter blocking device;
A described ratchet deciliter blocking device is the closed knob of spiral, right and wrong arm tension force pull-button, positioning spring or locating stud.
The invention has the beneficial effects as follows:
Providing a kind of can stop in the rotating shaft angle of setting, and the rotating shaft tie point can be loaded than the separating-closing type ratchet rotating shaft of big torsion when closed.
Can need rotating shaft to bear under the situation of big torsion at Folding furniture etc. uses.
Description of drawings:
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a side cross-sectional view of the present invention;
Among the figure: 1, fixed ratchet wheel; 2, spring groove; 3, spring; 4, reed; 5, hook tooth; 6, rotating shaft; 7, Telescopic spring; 8, ratchet deciliter blocking device; 9, movable ratchet.
Embodiment:
As shown in the figure:
The rotating shaft of separating-closing type ratchet is provided with the ratchet of two mutual interlocks that can separate, and it is that 1, one ratchet of fixed ratchet wheel is movable ratchet 9 that one of them ratchet is set;
The hook tooth 5 of described mutual interlock ratchet 1 is arranged on ratchet 1 circumference or ratchet 1 disk, and hook tooth 5 is arranged on ratchet 1 disk among the embodiment as shown in the figure;
Described fixed ratchet wheel 1 is fixedly connected with the rotating shaft 6 of concentric, movable ratchet 9 activities is set is rotatably connected in rotating shaft 6;
Described rotating shaft 6 is known non-angular restriction rotating shafts, angle limits rotating shaft, multistage torque rotary shaft, fixed point rotating shaft is arranged or freely stop rotating shaft;
Be provided with spring groove 2 at a ratchet 1, in spring groove 2, be provided with spring 3;
Length after described spring 3 compressions is less than or equal to the degree of depth of spring groove 2, and the length after spring 3 lax the resetting is greater than the length of hook tooth 5 and the degree of depth sum of spring groove 2;
Described hook tooth 5 is overall fixed structures, perhaps is provided with reed 4 in the end of hook tooth 5;
Described reed 4 is fixedly connected on hook tooth 5 ends, or movable telescopic is attached at hook tooth 5 inside, ejects in hook tooth 5 ends by a Telescopic spring 7;
When the end of hook tooth 5 was provided with reed 4, the length that spring 3 is lax after resetting should be greater than the length of hook tooth 5 standing parts and the degree of depth sum of spring groove 2, and less than the degree of depth sum of hook tooth 5 total lengths and spring groove 2;
At an end of separating-closing type ratchet rotating shaft 6, the arranged outside of movable ratchet 9 has ratchet deciliter blocking device 8;
Described ratchet deciliter blocking device 8 is the closed knob of spiral, right and wrong arm tension force pull-button, positioning spring or locating stud.
In an embodiment, ratchet deciliter blocking device 8 is the closed knobs of spiral.When rotational lock ratchet deciliter blocking device 8, the fixed ratchet wheel 1 and the 9 mutual interlocks of movable ratchet that separate can be born torsion greatly, when unclamping ratchet deciliter blocking device 8, spring 3 and Telescopic spring 7 are pushed fixed ratchet wheel 1 and movable ratchet 9 jointly open, and rotating shaft is freely rotated; Simultaneously, reed 4 can limit rotating shaft and produce multistage torsion.
Above embodiment is the unrestricted technological scheme described in the invention in order to explanation the present invention only; Therefore, though this specification describes in detail the present invention with reference to the foregoing description, one of ordinary skill in the art is appreciated that still and can makes amendment or be equal to replacement the present invention; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the invention, and it all should be encompassed among the claim scope of the present invention.
