Technical Field

The invention relates to a jack, in particular to an electric drill and hand-operated dual-purpose jack.

Background

The existing motor home jacks are generally divided into an electric motor home jack and a hand-operated jack, the electric motor home jack drives a transmission gear at the upper end of a screw rod to rotate through a motor and a speed reducing mechanism to jack the screw rod, the use is convenient, but the price is high, in the using process, a storage battery is in power shortage or the motor is damaged, the existing hand-operated jack comprises a jack body, the jack body consists of a screw rod, a screw rod seat, a transmission gear, a bevel gear, a gear shaft, a hand-operated handle, a gear shell, a telescopic outer tube, a telescopic inner tube and a base, the lower end of the telescopic inner tube is fixed with the base, the telescopic outer tube is sleeved outside the telescopic inner tube, the upper end of the telescopic inner pipe is fixed with a screw seat, the screw passes through the center of the screw seat and is in threaded connection with the screw seat, the upper end of the screw is fixed with a transmission gear, a bevel gear is arranged above the transmission gear and is meshed with the transmission gear, the center of the bevel gear is fixed with a gear shaft, the gear shell is a hollow cylinder with an opening at the lower end which is hollow, the opening end of the gear shell is covered outside the transmission gear, the bevel gear and the gear shaft, a through hole for the gear shaft to pass through is arranged on the gear shell, the penetrating side of the gear shaft is fixed with a crank handle, the transmission gear shaft and the bevel gear are driven by the crank handle to rotate to drive the transmission gear and the screw at the upper end of the screw to rotate so as to jack up, compared with the electric jack of a caravan, the hand-operated jack has stable quality and low price, but is labor-consuming, meanwhile, the hand-operated electric tools are commonly used in the existing life, and can be hand-operated on multi-caravans, therefore, if a flashlight-integrated motor home jack which can be matched with a handheld electric tool for use can appear on the market, the defects of the existing electric jack and the existing manual jack can be overcome.

Disclosure of Invention

In view of the defects of the existing jack, the invention aims to solve the technical problem of providing the electric-driven and hand-driven dual-purpose jack which is low in price and long in service life.

In order to achieve the above object, according to one aspect of the present invention, the present invention is achieved by the following technical measures: an electric drill and hand crank dual-purpose jack, comprising: the jack body, its gear shaft outside of jack body still is fixed with the hexagonal head, the hexagonal head is in the gear housing outside of jack body, still is equipped with the adapter simultaneously on the gear shaft between the bevel gear on hexagonal head and the gear shaft, and the adapter is fixed with the gear shaft, and the adapter also is in the gear housing outside, the activity is fixed with on the adapter and drives adapter pivoted crank.

This jack is fixed with the hexagonal head in the gear shaft outside on the basis of current hand jack, and handheld electric tool sleeve just can electrically drive the lift jack after the hexagonal is overhead like this, still is fixed with the adapter on the gear shaft simultaneously, and the back on the adapter is fixed to the crank, also can be through the manual lift jack of crank, and the crank need be demolishd when the hand changes electronically in the above-mentioned structure certainly.

Further, the adapter is equipped with a horizontal centre bore, and the aperture of centre bore is greater than the external diameter of gear shaft, the crank includes the rocker and fixes the crank in the rocker upper end, and the rocker both sides are turned over ninety degrees to same direction and are used for six square heads of joint, and the rocker lower extreme downwardly extending has the extension, and two extension cards are fixed by the bolt behind the adapter outside, the rocker can make a round trip to overturn. Above-mentioned design is for convenient use, only need among hand and the electronic conversion turn over the rocker can, use also comparatively safety simultaneously, when guaranteeing hand state, the hexagonal head of being connected with electric tool is not exposed, if want to drive with electric tool, just must overturn the crank, exposes the hexagonal head promptly.

Furthermore, a rectangular clamping block extends downwards from the bottom of the adapter, and two extending parts of the rocker are arranged on two sides of the rectangular clamping block. The design structure is reasonable.

Further, the gear ratio between the bevel gear and the transmission gear of the jack body is 1: 2.5. The handheld electric tool with the design has the most ideal driving effect.

Compared with the prior art, the invention has the advantages that: this hand dual-purpose jack of electricity drive had both possessed car as a house hand jack's stability and the advantage of low price, can generally be with the help of handheld electric tool to jack driven convenient to use's advantage again, and life is also comparatively permanent simultaneously.
