In the example shown in Fig. 2-7, its constructions is described as follows:
- -- an
air pump 202 directly couples with the rear side of thedrive motor 210 or has a pull/push or rotary movable mechanical structure to make theair pump 202 become engaged or disengaged with themotor 210. - -- the front shaft of a positively or reversely driven
motor 210 is in an elongated shaft shaped, and is in aterraced rod shape 211 with a slightly smaller diameter, and the diameter of its front section is larger, the middle section of the said terraced rod has anaxial key slot 212 and its end section hasthreads 213, the end of its smaller terraced rod also has lock opening 214, the end of the elongated shaft close to the motor has anannular slot 216 to receive alimiting snap ring 215 therein; - -- a
worm rod 216 with a smooth round hole inside couples with the drivefemale worm gear 217 of the sprial jack, its one end close to the motor is flat and smooth, whilst the other end has a tooth-shaped surface 218 for coupling transmission and its centre has ahole 219 with a slightly inward recess; - -- a ring-
shaped spring 220 to be set into the saidrecess hole 219; - -- an annular structure for the tooth-
shaped surface 218 of the above said worm rod for the transmission coupling its feature lies in that it has around hole 221 in its centre, its side to couple with the tooth-shaped surface 218 of the worm rod using for coupling transmission has an opposite and complementary tooth-shaped structure 222 and a recess shapedhole 223 to receive the above-saidring spring 220 also has anaxial key slot 224, an elongated strip shaped key slot 225 is to be set into a place between the above saidkey slot 224 and thekey slot 212 of the shaft to make both of them mutually conduct the transmission; this transmission coupling annular structure is to make the annular structure tightly press against the ring-shaped spring 220 when the annular structure is pushed by an external force and then couple with thecoupling tooth 218 on the side face of the worm rod for transmission, and when the tightly pressing external force vanished, the ring shaped structure is bounced away by thespring 220; - -- an
operating ring 226 having threads inside couples with thethreads 213 on the end of the terraced rod with a larger diameter on the front section of the elongated shaft, the tightly screwing of the ring 326 into thethreads 213 is to force the transmission coupling annular structure and to engage the worm rod and also the release thereon, thereby making both of them bounced apart by the ring-shaped spring for separation; - -- an
auxiliary knob 227 uses afixed pin 228 to insert thepin hole 214 of the end of smaller diameter of the elongated shaft of the motor for manually fixing the motor shaft in order to convenience the operation, when the above said operating ring is rotated. - To join the above-said structure, we can conduct the following operations;
- -- To tightly screw the operating ring is to tightly press the coupling ring and the worm rod thereby making them driven by the motor into motion, which, in turn, drive the female worm gear with threads inside to drive the screw of the spiral-type jack jacking up, or the reverse revolution of the motor makes the spiral-type jack lowered downwardly;
- -- to release the operating ring is to make the coupling ring and the screw separated and thus the jack structure part not driven by the motor into motion;
- -- if the relationship between the air pump and the motor is of the direct coupling, it is constantly driven by the motor since the required horse power is constantly smaller than that of the jack, that the air pump is used concurrently with the jack will never adversely affect the driving over the jack, in consideration of the economic type, it way is adoptable, and if it is necessary to conduct the clutch actions, it can conduct the clutch action and add usual mechanic or electro-magnetic clutch according to the needs.
- Fig. 2-7 shows its structure used for the drive of shear jack, its applicable example are shown in Fig. 2-8, 2-9 and 2-10, in which the based
seat 280 is used for installation of 4 sets of supportingarms 281 on it; the lower parts of supporting set is coupled with the based seat usingcoupling pin 282, and its upper parts is also coupled with the supporting plate using acoupling pin 282; its two ends are coupled usingscrew hole pin 285 for the penetration of screw rod 216', thechute 289 on the guide rod is limited by thecoupling pin 288 of penetratedhole 287 with thelimited pin 286, thus the guide rod 216' is limited for its rotation; the relationship of the guide rod andcoupling pin 288 with the penetratedhole 287 is the rotation in the original position, so that thescrew hole pin 285 combinated screwedly by guide rod 216' is moved and let supportingarm 281 move upper supporting plate for upward and downward motion. - The above-said various air pump and oil pump devices applicable to the oil hydraulic jacks and using a common drive motor can be further in the examplary state of the separate type just like the marketed pumps and the jack bodys as shown in Fig. 3 to conveniently meet the requirements of the special places, so this is the structural example which can be changed in its design and uses.
- The above-said various compound structures can be further made into the AC/DC dual purpose type as shown in Fig. 4, its feature lies in that inside the base a
transformer 401 is provided to transform the household power supply into a low voltage output, its low voltage output end is connected to arectifier 402 forthe low voltage output, its output end can also be connected in parallel to the socked 403 on the above said DC input end to drive the above saidDC motor 404 for driving the air pump or jack into motion, and thisinput socket 403 can make the DC output to act as a charger, or an output terminal is added to serve as a charger, thereby further making the invention become a tri-functional compound tool form, in this structure, aswitch 405 is connected in series with the input end of theDC motor 404 to cut off theDC motor 404, when it serves as a charging power supply. - The above said various descriptions and examples mainly provide the compound device of the air pump and the jack using a common motor as the objective of the invention with disclosures concerning the practicalizable evidences and various mutually compatible means, if compared with the conventional separately installed motors, the common motor in the invention has indeed the multiplification effects, especially its means with the economic benefits are simple and feasible, so this is a practicalizable design without any doubt.
