Description

A kind of Motorized lift device on tatami lifting platform

Technical field

The utility model relates to lifting device more particularly to a kind of Motorized lift devices on tatami lifting platform.

Background technique

Tatami is a kind of commonly used design of Japanese interior decoration, is increasingly received by the market in recent years, in this background Under, liftable tatami is with its diversified function by high praise.Liftable tatami includes tatami elevator and lid Plate, cover board are fixed above the top plate at the top of tatami elevator, are moved up and down with tatami elevator, presently the most often Tatami elevator is frequently with electronic mode, pneumatic type.

Wherein being existed using the tatami elevator fluctuation of service of electronic mode, lifting operation is not smooth enough, quick, and The shortcomings that shaking is easy in lifting process.

Utility model content

The purpose of this utility model is to provide a kind of structures to be simple and convenient to operate, operates stable electronic tatami liter Falling unit.

Technical solution adopted in the utility model is:

A kind of Motorized lift device on tatami lifting platform, including for being connect with ground bottom casing, be placed on On the casing of bottom and the middle sleeve that can slide up and down, it is placed on middle sleeve and the top cover pipe that can slide up and down；The top cover pipe and bottom It is equipped between casing and passes through motor-driven elevating screw component；Bottom cannula cavity bottom is equipped with the control being connected to motor Device.

As a preference, the elevating screw component includes the internal screw thread silk braid bar for being loaded on top cannula tip, is loaded on The external screw thread screw rod of bottom sleeve bottom, the hollow connection wire rod for connecting internal screw thread silk braid bar and external screw thread screw rod；The external screw thread Screw rod is connected to motor.

As a preference, the bottom cannula tip inner wall is equipped with the downlink restricted driving for controlling falling head and opens It closes, the uplink for controlling lifting height is restricted driving and switched.

As a preference, the uplink, which is restricted driving, to be switched across there is lifting wire rope, is worn on the lifting wire rope There is the touch block for being located at uplink restricted driving switch lower section.

As a preference, rechargeable battery is connected on the controller.

The utility model has the advantage that this elevating lever controls motor by controller and goes up and down elevating screw component, Controller is returned by uplink restricted driving switch, downlink restricted driving switch feedback signal simultaneously, keeps the lifting position of elevating lever more accurate； Elevating lever can provide power supply by external alternating current or built-in rechargeable battery；Remote controller module in controller can be with remote controler Connection and control, make this elevating lever have the advantages that structure be simple and convenient to operate, operate it is stable.

Detailed description of the invention

Fig. 1 is the cross-sectional view of the utility model.

Fig. 2 is the partial enlargement diagram of the utility model.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and detailed description.

As Figure 1-Figure 2, a kind of Motorized lift device on tatami lifting platform, including for being connect with ground Bottom casing 1, be placed on bottom casing 1 and the middle sleeve 2 that can slide up and down, be placed on middle sleeve 2 and the top cover that can slide up and down Pipe 3, top cover pipe 3 are connect with cover board；The elevating screw component 5 driven by motor 4 is equipped between the top cover pipe 3 and bottom casing 1； 1 intracavity bottom of bottom casing is equipped with the controller 6 connecting with motor 4, and controlling motor 4 by controller 6 makes elevating screw group Part 5 is started to work, when bottom casing 1, middle sleeve 2, top cover pipe 3 mutually set poststack elevating lever complete reduction movement；When bottom casing 1, Elevating lever completes raising movement after middle sleeve 2, top cover pipe 3 mutually stretch.

The elevating screw component 5 includes the internal screw thread silk braid bar 51 for being loaded on 3 top of top cover pipe, loaded on 1 bottom of bottom casing External screw thread screw rod 52, connect internal screw thread silk braid bar 51 and external screw thread screw rod 52 hollow connection wire rod 53；The external thread wire Bar 52 is connect with motor 4, is driven external screw thread screw rod 52 to rotate after motor 4 operates, is made internal screw thread silk braid bar 51, external screw thread screw rod 52, it is mutually rotated between hollow connection wire rod 53, completes the movement raised and reduced, pass through the internal screw thread silk braid bar that position is fixed 51 and external screw thread screw rod 52, make hollow connection wire rod 53 is not in positional shift during rotation, makes to go up and down more smoothly Flexibly.

For the lifting action for further controlling elevating lever, it is equipped in 1 top inner wall of bottom casing for controlling decline The downlink restricted driving switch 7 of height, the uplink restricted driving switch 8 for controlling lifting height, desktop after decline push downlink limit Feeler lever on row switch 7 closes downlink restricted driving switch 7, feeds back back into electric signals to control panel, motor 4 is made to shut down；Work as liter When dropping bar rising, passing through on uplink restricted driving switch 8 has lifting wire rope 9, is installed on lifting wire rope 9 and limits positioned at uplink The touch block 10 of 8 lower section of row switch, pulls wirerope after desktop rising, when wirerope draws high preset position, touches Block 10 can go up the feeler lever that pressure uplink is restricted driving on switch 8, close downlink restricted driving switch 7, feed back back into electric signals to control panel, make electricity Machine 4 shuts down.

To avoid desktop during decline, the appearance obstacle of desktop, such as leg, stool, cause personal injury or because It can not decline and motor 4 is caused to dally, damage, protection limit switch 11 is equipped at the top of the top cover pipe 3, makes table Plate meet with obstruction during decline object when, can in time out of service, the safety of protection staff.
