Background technology
At present, for vehicle-mounted jack, it is mainly screw jack, screw jack structurally generally includes jacking block, screw, shed stick, screw rod, base, jacking block and screw rod are fixed together by screw, shed stick is through the through hole at the top of screw rod, screw rod is connected with whorl of base, rotate shed stick by 360 °, screw rod carries out relative the rotation under the effect of screw pair with base, thereby realize the vertical lines motion of screw rod, the drive jacking block is risen, when rising heavier object, the user's who needs strength is larger, be unfavorable for that the user that strength is less uses, need 360 ° of rotations of shed stick when rising, requisite space is larger, be not suitable for the smaller occasion of space behavior scope, and when just starting to rise jack, for firmly convenient, need to continually shed stick be extracted from the through hole of screw rod then and insert, make operation more loaded down with trivial details.
The utility model content
The utility model will solve the problem that above-mentioned prior art exists, a kind of vehicle-mounted single direction ratchet formula jack is provided, rational in infrastructure, easy to use, the simple operation smoothness, can save user's strength, and when rising, do not need the user repeatedly to plug the rotation shed stick, operational space scope angle reduces, and has met people's demand.
The utility model solves the technical scheme that its technical matters adopts: this vehicle-mounted single direction ratchet formula jack, comprise base, base is provided with the connecting rod that base moves up and down relatively, the connecting rod diamond shaped arranges, the lower end of connecting rod is movably connected on base by rotating shaft one, the top of connecting rod is equipped with jacking block, connecting rod is flexibly connected by rotating shaft two and jacking block, the left end of connecting rod is provided with the left-hand rotation piece, the cylindrical shape setting in the two ends of left-hand rotation piece, the right-hand member of connecting rod is provided with the right-hand rotation piece, the cylindrical shape setting in the two ends of right-hand rotation piece, between left-hand rotation piece and right-hand rotation piece, cross-under has screw rod, the two ends of screw rod pass respectively left-hand rotation piece and right-hand rotation piece, the left end of screw rod is connected with left-hand rotation piece screw thread fit, be installed with ratchet on the right-hand member of screw rod, ratchet is provided with handle, handle is provided with and blocks the ratchet external tooth and promote the ratchet that ratchet rotates when handle rotates, the outside of ratchet is provided with the speed handle be plugged on the screw rod right-hand member.After arranging like this, rational in infrastructure, easy to use, during use, by low-angle repeatedly, the reciprocating rotation operating handle, ratchet is done unidirectional clockwise rotating under the promotion of handle ratchet, thereby drive screw rod and do unidirectional clockwise rotating, screw rod is threaded connection upwards to be risen connecting rod, jacking block is risen weight under the effect of connecting rod, after finishing using, the speed handle be plugged on screw rod is rotated counterclockwise, thereby driving screw rod rotates counterclockwise, connecting rod drives jacking block and descends under the effect of screw rod, complete the process of rising weight, the angle of operational space scope has just reduced like this, and when rising, only need turning handle can realize rising the effect of weight, the simple operation smoothness, can save user's strength, result of use is good.
Rotating shaft one is fixedly mounted on base by latch one.After arranging like this, rotating shaft one can be fixedly mounted on base, facilitates connecting rod to use.
Rotating shaft two is fixedly mounted on jacking block by latch two.After arranging like this, rotating shaft two can be fixedly mounted on base, facilitates connecting rod to use.
The effect that the utility model is useful is: vehicle-mounted single direction ratchet formula jack of the present utility model, rational in infrastructure, easy to use, only need the process that repeatedly the Small-angle Rotation operating handle can realize rising weight when rising, the angle of operational space scope has just reduced like this, and the simple operation smoothness, can save user's strength, result of use is good, is beneficial to popularization.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model embodiment front;
The structural representation that Fig. 2 is the utility model embodiment back side.
Description of reference numerals: base 1, connecting rod 2, rotating shaft 1, jacking block 4, rotating shaft 25, left-hand rotation piece 6, right-hand rotation piece 7, screw rod 8, ratchet 9, handle 10, ratchet 11, speed handle 12, latch 1, latch 2 14.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to accompanying drawing: the vehicle-mounted single direction ratchet formula jack in the present embodiment, comprise base 1, base 1 is provided with the connecting rod 2 that base 1 moves up and down relatively, connecting rod 2 diamond shaped settings, the lower end of connecting rod 2 is movably connected on base 1 by rotating shaft 1, the top of connecting rod 2 is equipped with jacking block 4, connecting rod 2 is flexibly connected by rotating shaft 25 and jacking block 4, the left end of connecting rod 2 is provided with left-hand rotation piece 6, the cylindrical shape setting in the two ends of left-hand rotation piece 6, the right-hand member of connecting rod 2 is provided with right-hand rotation piece 7, the cylindrical shape setting in the two ends of right-hand rotation piece 7, between left-hand rotation piece 6 and right-hand rotation piece 7, cross-under has screw rod 8, the two ends of screw rod 8 pass respectively left-hand rotation piece 6 and right-hand rotation piece 7, the left end of screw rod 8 is connected with left-hand rotation piece 6 screws thread fit, be installed with ratchet 9 on the right-hand member of screw rod 8, ratchet 9 is provided with handle 10, handle 10 is provided with and blocks ratchet 9 external tooths and promote the ratchet 11 that ratchet 9 rotates when handle 10 rotates, the outside of ratchet 9 is provided with the speed handle 12 be plugged on screw rod 8 right-hand members.
