Description

Hand chain wheel device of sliding door

Technical Field

The utility model relates to an appurtenance that is used for manual lift door to start, specifically speaking are hand power sprocket device of lift door.

Background

A sliding door is an industrial door that lifts and lowers a door panel by means of rails and rollers passing through the sides of the door panel. At present, the manual sliding door commonly used at home and abroad is a door plate pulled by ropes or purely manually, has no other auxiliary structure, and has the characteristics of low cost and simple structure. However, when a large door panel is used, the force required to open and recover the door panel is large, and the use is inconvenient. There is therefore a need for a manual assist device that is not easily damaged and that can effectively assist in opening and closing a door panel.

Disclosure of Invention

The utility model discloses a solve current problem, aim at providing a hand power sprocket device of sliding door.

In order to achieve the above object, the utility model discloses an among the technical scheme, the door plant both sides of sliding door are equipped with the gyro wheel that goes up and down in the track, including rotatable gear wheel and pinion, wherein: the big gear is driven to the small gear through a chain; the rotating shaft of the pinion is connected with a rotating shaft driving piece of the sliding door.

Wherein, the rotating shaft of the big gear is provided with a hole for inserting a wrench; the large gear can be manually driven to rotate after the wrench is inserted into the hole.

Wherein the holes are regular hexagons.

Wherein, the extension part of the rotating shaft of the pinion is fixedly connected with the axle center of the chain wheel; the chain wheel synchronously rotating with the pinion drives the door plate of the sliding lifting door to lift along the track through another chain.

The bottom ends of the rotating shafts of the large gear and the small gear are respectively and rotatably connected with the bottom plate through bearings.

The bearing is arranged in a positioning piece, and the positioning piece is fixedly connected with the bottom plate through a locknut. An upper cover is further arranged above the pinion, and the top end of a rotating shaft of the pinion is rotatably connected with the cover surface of the upper cover.

The left end and the right end of the upper cover are fixedly connected with the bottom plate through the connecting plate respectively.

Compared with the prior art, the utility model has the advantages that the large door plate can be pulled by a person with small force by reducing the rotating speed through the chain transmission of the gears with different sizes, so that the use is more comfortable, and the structure is simpler; the sliding door can be driven by the motor to be manually driven, so that the cost can be reduced, the sliding door is not easy to damage, easy to install and maintain and convenient to operate.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention;

fig. 2 is a schematic diagram of the embodiment of the present invention;

fig. 3 is a schematic perspective view of an embodiment of the present invention;

referring to the attached drawings, a bottom plate 1, a large gear 2, a small gear 3, a bearing 4, a chain 5, a rotating shaft 6, a locknut 7, a hole 8 and an upper cover 9.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings.

Referring to fig. 1 to 3, fig. 1 to 3 show that, according to an embodiment of the present invention, rollers that go up and down in the track are disposed on both sides of the door panel of the sliding door, and the door panel on the top of the sliding door is provided with a rotating mechanism that lifts up and down the door panel. The present embodiment mainly comprises a rotatable bull gear 2 and a pinion gear 3; wherein the gearwheel 2 has a diameter which is 3.5 times larger than the pinion 3. The gearwheel 2 is driven by a chain 5 to the pinion 3, and the rotation shaft of the pinion 3 is connected with a driving piece of a rotation shaft 6 of the sliding door. The bottom ends of the rotating shafts 6 of the big gear 2 and the small gear 3 are respectively rotatably connected with the bottom plate 1 through bearings 4. Furthermore, the bearing 4 is arranged in the positioning piece, the bearing 4 is arranged in the cavity of the positioning piece, and the lower end of the positioning piece is fixedly connected with the bottom plate 1 through the locknut 7. Further, referring to fig. 2, the rotating shaft 6 of the large gear 2 is provided with a hole 8 for inserting a wrench; after one end of the wrench is inserted into the hole 8, the other end of the wrench is driven by hand to rotate, and then the gearwheel 2 rotates. The holes 8 are regular hexagons, which is beneficial to mechanical transmission.

Wherein, the extension part of the rotating shaft of the pinion 3 is also fixedly connected with the axle center of the chain wheel; the chain wheel rotating synchronously with the pinion 3 drives the rotating mechanism of the sliding lifting door through another chain, so that the door plate can lift and descend along the track. Wherein, an upper cover 9 is also arranged above the pinion, and the left end and the right end of the upper cover 9 are respectively and fixedly connected with the bottom plate 1 through a connecting plate; the top end of the rotating shaft of the pinion 3 is also rotatably connected with the cover surface of the upper cover 9 by the bearing 4. The upper end and the lower end of the rotating shaft of the pinion 3 are both fixed, so that the rotating stability is higher, and the lifting quality of the door plate is improved.

The embodiments of the present invention have been described in conjunction with the accompanying drawings and examples, the structures of which are not intended to limit the present invention, and those skilled in the art can make modifications as required, and all changes and modifications within the scope of the appended claims are within the scope of protection.
