Abstract
The utility model provides a portable powerful jack which at least comprises bearing bars, load-bearing rods, a leading screw, a hand wheel and fixing grabs, wherein, the hand wheel is arranged at one end of the leading screw, and the fixing grabs are respectively arranged on both sides of the head ends of the load-bearing rods. The portable powerful jack is characterized in that the tail ends of the two load-bearing rods are movably connected together through the first bearing bar; joints are respectively arranged on the middle sections of the two load-bearing rods; the two joints are respectively and movably connected with one end of two supporting rods; the other ends of the two supporting rods are movably connected together through the second bearing bar; the leading screw penetrates the center of the second bearing bar and is closely connected with the second bearing bar; the leading screw further penetrates an internal thread hole in the center of the first bearing bar; and an external thread on the leading screw is matched with the internal thread hole. The utility model has the advantages of simple structure, subtle design, small volume, convenient carrying and smaller cross section, and can enter in the narrow space for operation and can finish the working load which is failed to be finished by similar products with the same volume.
Description
Technical field
The utility model relates to a kind of engineer equipment, relates in particular to a kind of portable jack energetically.
Background technology
At present its volume of jack is too huge energetically for majority, and quality is heavier, complicated operation and be not easy to carry.In the time need working under the less environment in space, the jack energetically of larger volume can't enter, and makes to take measures necessary in the very first time a lot of crucial moments.
The utility model content
The utility model is in order to solve the above-mentioned problem of mentioning, a kind of portable jack energetically to be provided, and its technical scheme that adopts is as described below.
A kind of portable jack energetically, at least comprise bearing bar, bearing bar, leading screw, handwheel and fixedly grabbing, described handwheel is located at an end of leading screw, the head end both sides of described bearing bar respectively are provided with one and fixedly grab, wherein, first bearing bar links together the tail end of two bearing bars in the mode that flexibly connects, the stage casing of described two bearing bars respectively is provided with a joint, these two joints connect an end of two strut bars respectively in the mode that flexibly connects, the other end of described two strut bars links together in the mode that flexibly connects by second bearing bar, one leading screw passes the described second bearing bar center and is leak-tight joint with it, described leading screw also passes the internal thread hole at the described first bearing bar center, has outside thread to match with described internal thread hole on the described leading screw.
Wherein, described flexible connection is to cooperate nut to pass described bearing bar and first bearing bar, joint and strut bar, strut bar and second bearing bar with set pin.
The utility model is simple in structure, and deft design has the advantages that volume is little, easy to carry, cross-sectional plane is less, can enter that small space carries out operation.It can finish the inaccessiable workload of like product equal volume.

The specific embodiment
Now, the utility model is further described according to accompanying drawing.
Embodiment
Please participate in Figure 1 and Figure 2, the major part of portable jack energetically comprises strut bar 4,9, the second bearing bars 6, first bearing bar 23, leading screw 8, bearing bar 16,26 and handwheel 22 among the utility model embodiment.
Wherein, first bearing bar 23 is connected with nut 24 by short set pin 21 with the tail end of bearing bar 26, first bearing bar 23 is connected with nut 19 by short set pin 20 with the tail end of bearing bar 16, described bearing bar 26,16 stage casing respectively is provided with joint 29,30, joint 29 is connected with nut 3 by long set pin 25 with an end of strut bar 4, joint 30 is connected with nut 10 by long set pin 15 with an end of strut bar 9, the other end of strut bar 4 is connected with nut 5 by short set pin 18 with second bearing bar 6, the other end of strut bar 9 is connected with nut 7 by short set pin 17 with second bearing bar 6, leading screw 8 passes the center of second bearing bar 6 and is leak-tight joint with it, leading screw 8 also passes the internal thread hole at the center of described first bearing bar 23, there is outside thread to match on the described leading screw 8 with described internal thread hole, one end of described leading screw 8 is provided with handwheel 22, the head end both sides of described bearing bar 26 are respectively equipped with fixedly grabs 28, fixedly grab 2, bearing bar 26 with fixedly grab 28,2 pass through short set pin 27 is connected with nut 1, the head end both sides of described bearing bar 16 are respectively equipped with fixedly grabs 13, fixedly grab 12, bearing bar 16 with fixedly grab 12,13 pass through short set pin 14 is connected with nut 11.
Described portable jack energetically is when work, rotating handwheel 22 earlier tries one's best away from second bearing bar 6 leading screw 8 rotations and then first bearing bar 23 mobile first bearing bar 23 that makes on leading screw 8, this moment, described jack energetically was in compressive state, with described energetically after jack is put into control position, fixedly to grab 12,13 paste ground, fixedly grab 2,28 promptly treat lifting object lower edge after, with backward rotation handwheel 22, handwheel 22 thereby drive leading screw 8 rotate, first bearing bar 23 on the leading screw 8 moves towards the direction near second bearing bar 6, this moment strut bar 4,9 change synchronously with the angle of leading screw 8, when leading screw 8 and strut bar 4, when 9 angle was 90 °, described jack had energetically reached maximum rising height.
