Description

Manual opening and closing unit for vinyl house {Ventilating unit for vinyl house}

The present invention relates to a manual switchgear for a plastic house, and more specifically, one planetary gear formed inside the fixed inner tooth is rotated by meshing with a gear formed inside the fixed inner tooth by a carrier and an input shaft and simultaneously rotating the output shaft inner tooth. In order to rotate it, the reducer is configured to the minimum size and the reducer has an automatic brake function in which the direction and the direction of the force acting on the gears are applied dynamically.

In general, the manual switch for the vinyl house is configured to transmit rotational force to only one side, and the manual switch for the vinyl house is configured to rotate the driven shaft through its input shaft when the main shaft is rotated by the handle.

In addition, the driven shaft is connected to the vinyl house ceiling and the vinyl winding shaft of the side window to open or unwind the vinyl and open and close the ceiling and side windows of the vinyl house.

However, the conventional manual switch for a vinyl house has various types of products using worm gears, but has a problem in that the wear of the gears is large and the deceleration efficiency is low because it is a frictional power transmission method by the inclination angle of the worms and worm gears. The products of the type that decelerate spur gears externally are equipped with two pairs of ratchets, ratchet wheels and gears to prevent the reverse rotation of the reducer. There is a disadvantage that can not be used efficiently, in particular, when using for opening and closing the skylight of the plastic house, a separate holding pipe should be installed to prevent the reverse rotation of the vinyl winding rod, and there is a hassle to move the holding pipe together during the opening and closing work.

In addition, there is a 'vinyl house switchgear' of Utility Model Registration No. 2000-009575 as a prior art to solve the above problems.

It is provided with a ring receiver and a housing formed with a driven shaft support for supporting a driven shaft in a concentric circle in the ring receiver, and a cylindrical clutch ring fitted to the ring receiver and fixed therein, and a clutch spring inside the clutch ring. The cover is provided with a cover covering the open top of the housing, and a drive shaft having a drive shaft gear between the cover and the housing is provided on the same axis as the driven shaft, and the clutch spring is wound while the drive shaft is rotated forward and reverse. The driving part to be separated from the ring is provided on the drive shaft, and the driven shaft is provided with a driven part for rotating the driven shaft in contact with the driving part, and when the driven part is rotated forward and backward by magnetic force, the clutch spring is released while the driven spring is released. It is configured to be in close contact with the driven shaft.

However, the above-mentioned vinyl house switch has a structure that prevents the rotation of the driven shaft due to the enlarged outer diameter of the clutch spring and closes the clutch ring. In particular, the elastic force of the spring is increased due to frequent use and difficulty in manufacturing the clutch spring. There is a problem of deterioration.

On the other hand, there is a 'speed reducer with automatic brake function' of the Patent Registration Application No. 2001-18058 of the present application for the purpose of solving the above problems and when compared with the purpose of the present invention, the method is the same but applied part of the present invention Is specifically described.

The present invention is devised to solve the above-described problems, the switch is configured so that the rotation direction of the input shaft and the rotation direction of the output shaft is the same, and can obtain various reduction ratios of low ratio, the same reduction ratio, in the same module The purpose of the present invention is to provide a manual switchgear for a vinyl house with an automatic brake function, which has a minimum size as compared to the other switchgear mentioned above, and which dynamically applies the direction and the direction of movement between the gears. .

In order to achieve the above object, one planetary gear formed inside the fixed internal gear is engaged with the gear formed inside the fixed internal gear by the carrier and the input shaft to rotate and the output shaft internal gear can be rotated. In the case of one rotation, if the planetary gear rotates one turn along the inner circumference of the fixed inner tooth by the shaft fixed to the carrier rotating about the input shaft, the inner tooth formed on the output shaft rotates by the number of teeth of the fixed inner tooth. It relates to a manual switchgear for a plastic house that can open and close the ceiling or side windows of the house.

A part enlarged view of a state in which the brake function, which is a main part, operates, FIG. 8 is a perspective view of another use state of the present invention, and FIG. 9 is a cross-sectional view of another use state of the present invention.

First of all, the operation of the manual switchgear for the present vinyl house is made by the following structure and configuration.

As shown in FIG. 3, one planetary gear 10 assembled inside the cover 18 and the fixed internal gear 11 is inserted into and fixed to the planetary gear support shaft 15 formed in the carrier 14. The input shaft 13 integrally formed with the 14 is inserted into the fixing groove 16 of the fixed internal tooth 11 so that the handle 17 can be coupled.

And the planetary gear 10 is assembled to the planetary gear support shaft 15 of the carrier 14 as shown in Figure 2 is configured to be engaged with the output shaft internal gear 12.

Therefore, the planetary gear 10 formed integrally with the carrier 14 is formed to be engaged with the fixed internal gear 11 and the output shaft internal gear 12 at the same time.

In addition, the fixed internal gear 11 is fixed to the cover 18, the planetary gear 10 and the output shaft internal gear 12 is configured to rotate with each other.

Meanwhile, when a force is transmitted by fixing the handle 17 to the input shaft 13 integrally formed with the carrier 14, the carrier 14 drives the planetary gear 10 while generating a force to rotate.

At this time, the planetary gear 10 is rotated along the gear formed in the fixed internal gear 11 and at the same time to rotate the output shaft inner gear 12 and to operate the vinyl winding shaft 22.

In such a situation, the size of the output shaft internal tooth 12 is larger than the fixed internal tooth 11 by 1 tooth or more, and the dimension of the planetary tooth 10 is 1 tooth or more larger than the fixed internal tooth 11 by the number of teeth. Configure less.

In addition, the number of the planetary gear 10 is one, so that the rotation direction of the input shaft 13 and the rotation direction of the output shaft is the same.

Referring to the operation and effects of the present invention configured as described above in detail with reference to FIG.

When the present invention configured as described above is used for opening and closing the vinyl house side window in the same manner as usual, the socket 26 fixed to one side of the vinyl winding rod 28 connected to the vinyl located on the side of the vinyl house The output shaft 23 of the manual switchgear for the vinyl house is connected, and the guide roller 19 formed integrally with the bracket 20 attached to the manual switchgear for the vinyl house is supported by the guide support (not shown).

In this case, when the vinyl of the vinyl house is wound, when the handle 17 of the vinyl switch is rotated in the winding direction, when the force is transmitted clockwise to the input shaft 13 formed integrally with the carrier 14, the carrier 14 is The planetary gear 10 which is simultaneously driven by the internal gear 12 formed on the fixed internal gear 11 and the output shaft 23 while generating a force to rotate clockwise again is clocked along the fixed internal gear 11. While rotating in the direction (→) and rotating in the counterclockwise direction (←) around the axis, the inner winding 12 formed on the output shaft 23 is rotated in a clockwise direction (→) while decelerating the vinyl winding rod. By rotating it, the vinyl of the vinyl house is wound up.

On the other hand, when using the present invention for opening and closing the ceiling of the plastic house as shown in FIG. 8, the guide roller 19 and the handle 17 formed integrally with the bracket 20 attached to the manual switch of FIG. Bevel gear 24 shown in the attached to the housing 25 is assembled to be fixed.

The output shaft 23 of the switch 29 is connected to the socket 26 assembled to one side of the vinyl winding rod 28 positioned on the roof of the vinyl house, and the input shaft 13 of the switch is assembled as described above. Another socket 26 formed on the fixing bar 27 is fixed.

In the above situation, the output shaft 23 assembled with the socket 26 fixed to the vinyl winding rod is preferably fixed by the fixing pin 30, and the socket 26 and the vinyl winding rod 28 and the connecting bar are always fixed. 27 is configured to fasten and fix the direct connection screw 31.

In addition, the connecting bar 27 is made of the same material as the vinyl winding rod, and cut to a suitable length according to the height of the vinyl house and fixed to the socket 26 formed on the input shaft, the handle for the skylight below the connecting bar 27 It is a structure fixed to the socket 26 formed in the 21.

At this time, the handle 21 integrally formed with the connection bar 27 does not need a separate holding pipe or guide device, and also by the weight of the connection bar 27 and the handle 21 connected to the manual switchgear The winding rod can control the force to reverse.

Therefore, the opening and closing of the ceiling of the vinyl house is facilitated by the input shaft 13, the output shaft 23, and the handle 21 formed on the manual switch 29, and the direction of the switch in the direction of rotating the handle. This is done.

In addition, as described above, when the vinyl in the side and the skylight of the vinyl house is wound in the upward direction by the manual switchgear and reaches the proper point, the handle 17 stops, and a load is generated to descend in the direction opposite to the winding direction in the direction of the output shaft. .

At this time, the planetary gear 10 formed inside the manual switch is generated by the output shaft internal gear 12 to rotate in the same direction as the load is generated, the teeth on the fixed internal gear 11 and the output shaft inner gear 12 at the same time. The bite planetary gear 10 has a force to revolve in a clockwise direction opposite to the direction of the load along the gear formed in the fixed internal gear 11 at the same time.

That is, the direction in which the planetary gear 10 intends to revolve is the same as the direction in which the output shaft internal gear 12 rotates in the upward direction, thereby generating a brake function.

As described above, when the direction of the load applied to the output shaft is in the opposite direction, the brake function is operated while the movement direction and the force in the opposite direction are applied, so that no separate brake means such as a ratchet gear and a ratchet for braking are required. Becomes simpler.

In addition, the present invention can be produced in large quantities because the configuration of the power transmission method is extremely simple and easy to manufacture and assemble.

The present invention described above is possible to those skilled in the art to which the present invention belongs to various modifications and changes can be made within the scope without departing from the technical spirit of the present invention in the foregoing embodiments and the accompanying drawings. It is not limited.

As described above, the present invention has a feature of minimizing its volume and weight and making it simple to compare with a manual switchgear for a conventional vinyl house, with a reduction in manufacturing cost and easier processing and assembly. It is a very practical design that can achieve perfect and safe brake function by the assembly of each gear alone.
