Abstract
The invention relates to an automatic clutch device used at a spring fixing end of an automatic spring door-closing hinge. The middle portion of a clutch shaft is located in a shaft sleeve of a fixed hinge sheet. One end of the clutch shaft is connected with a rotary hinge sheet. A clutch pin roller is located between the clutch shaft and the shaft sleeve of the fixed hinge sheet. A clutch inner sleeve is located between the clutch shaft and the shaft sleeve of the fixed hinge sheet. A through hole is formed in the clutch inner sleeve and used for the arrangement of the clutch pin roller (4). One end of a torsion spring is fixed to the clutch inner sleeve (3) and the other end of the torsion spring is fixed to the rotary hinge sheet (1). An inner groove (51) is formed in the inner wall of the shaft sleeve of the fixed hinge sheet (5) and an outer groove (21) is formed in the outer wall of the clutch shaft (2). When the rotary opening angle of the rotary hinge sheet (1) is alpha 2, the clutch pin roller (4) is transferred into the outer groove (21) from inner groove (51) so that the rotary hinge sheet (1) can stop in any position with the angle equal to or larger than the opening angle alpha 2.

The specific embodiment
Below in conjunction with Fig. 1 to Fig. 3, the present invention will be further described:
As shown in the figure, a kind of automatic clutch device for spring automatic door-closing hinge spring fixed end, comprise clutch shaft 2, clutch inner sleeve 3, clutch roller 4 and torsion spring 6, clutch shaft 2 mid portions are arranged in the axle sleeve of Fixed hinge sheet 5, and one end of clutch shaft 2 is connected with rotating close hinge 1.Clutch roller 4 is between clutch shaft 2 and the axle sleeve of Fixed hinge sheet 5, clutch inner sleeve 3 is between clutch shaft 2 and the axle sleeve of Fixed hinge sheet 5 and have through hole thereon for clutch roller 4 is set, one end of torsion spring 6 is to be fixed on clutch inner sleeve 3, one end is to be fixed in rotating close hinge 1 in addition, on the sleeve lining of Fixed hinge sheet 5, be provided with inner groovy 51, on clutch shaft 2 outer walls, be provided with outer groove 21; When rotating close hinge 1 rotarily opens angle [alpha]
2, clutch roller 4 is from inner groovy 51 is transferred in groove 21, and rotating close hinge 1 can stop at and be equal to or greater than opening angle α
2any one position on.
The present invention is as follows for the operating principle of the automatic clutch device of spring automatic door-closing hinge spring fixed end:
As shown in Figure 2, when rotating close hinge 1 and Fixed hinge sheet 5 closure state, by clutch roller 4, clutch inner sleeve 3 and Fixed hinge sheet 5 are locked together, clutch rotating shaft 2 is fixing in integrated state all the time with rotating close hinge 1.
As shown in Figure 3, clutch roller 4 makes clutch rotating shaft 2 with clutch inner sleeve 3 combinations and rotates together with rotating close hinge 1.When rotating close hinge 1, along hinge, open direction rotational angle with clutch rotating shaft 2 and be less than setting opening angle α
2time, the position of clutch inner sleeve 3 in relative stationary state (due to for close door torsion spring 6 one end be to be fixed on clutch inner sleeve 3, and one end is to be fixed in rotating close hinge 1 in addition, that is to say that torsion spring 6 can produce setting opening angle α in this process
2interior torsional deflection produces reaction force), when turning to be greater than, clutch rotating shaft 2 sets opening angle α
2time, clutch roller 4 departs from the outer groove 21 of also embeddeding clutch rotating shaft 2 from the inner groovy 51 of Fixed hinge sheet 5, and is fixed as one with clutch inner sleeve 3, is setting opening angle α
2to 180 ° of scope inter-syncs, rotate, that is to say that rotating close hinge 1 and clutch inner sleeve 3 synchronously rotate.Now, torsion spring 6 torsional deflections stop and being combined as a whole with rotating close hinge 1, clutch rotating shaft 2 and clutch inner sleeve 3.
In rotating close hinge 1, be opened to be greater than and set opening angle α
2to optional position, torsion spring 6 is being set opening angle α
2the elasticity that internal strain produces can be under energy accumulating state, and now rotating close hinge 1 can stop at arbitrarily a certain position.
When rotating close hinge 1 is being less than setting opening angle α
2time, torsion spring 6 can discharge elasticity automatically can make door automatically close.
The present invention has following characteristics for the automatic clutch device of spring automatic door-closing hinge spring fixed end:
1, a kind of spring automatic door-closing hinge spring fixed end automatic clutch device the present invention relates to, clutch roller 4, clutch inner sleeve 3 and clutch rotating shaft 2 are core parts of whole device.
2, single unit system can be realized by conventional machining process.
3, rotating close hinge 1 is set opening angle α in actual use
2generally can be set as 90 °, now the fixed angle of rotating close hinge 1 and clutch rotating shaft 2 China and foreign countries' grooves 21 can be α
1=50 °, the inner groovy 51 on Fixed hinge sheet 5 can be 30 ° with Fixed hinge sheet 5 mounting plane angles.
By reference to the accompanying drawings the present invention has been carried out to exemplary description above; obvious realization of the present invention is not subject to the restrictions described above; as long as the various improvement that adopted method design of the present invention and technical scheme to carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all in protection scope of the present invention.
