Abstract
The utility model discloses a manual hydraulic jack with relatively small displacement. A connection shaft, front and rear wheels on the front end and the rear end of the left and the right wall board, a channel is opened in the middle of the wall board, an oil cylinder assembly is provided on the connection board on the rear end of the wall board, a press device is provided on the oil cylinder assembly, and a handle is inserted therebetween. The oil cylinder assembly is connected to a sliding rack, guidance wheels are hinged on the left and the right side of the sliding rack, and embedded into rails respectively. The top lifting mechanism includes an oil cylinder assembly, a top lifting arm assembly, a containment tray, a long connection rod and a support rod. The upper end of the top lifting arm assembly is equipped with containment trays through triangular rack hinged thereto, and the lower corner of the rack is hinged to the upper end of the long connection rod. Because support rodis provided on the back of the top lifting arm assembly, not only the top lifting torque is increased relatively, but only the track of lifting the containment tray along the arc is changed due to the traction of the top lifting arm assembly by the support rod. Therefore, the displacement is relatively reduced, the risk of automobile sliding is relatively reduced, and it is beneficial to enhancing security during automobile repair.
Description
Technical field
The utility model relates to the lifting gear field, specifically refers to when automobile dismounting tire the less hand-hydraulic jack of automobile holder a kind of displacement overhead.
Background technology
The hydraulic jack that present automobile is provided for oneself, compressed-air controlled being arranged, also manually operated, these jack majorities are arranged all is with the side jack-up of less power with the heavy weight automobile, with the easy disassembly tire by lever principle.But in the jacking process, because the pallet of jack is along being the center of circle with jacking arm and the hinged end of base, length with it is the camber line rising of radius again, and the contact point at a certain position of pallet and car body is fixed, therefore car body will certainly produce displacement, if parking ground is some bevelleds words a little just, and all the other tires by chance do not fill up again and go up cleat or stone and so on, produce displacement in the case and will make automobile slippage forward or backward, the danger that this just might be difficult to expect.Pallet not being risen along camber line, reduce its displacement, then is this hydraulic jack design-calculated original intention.
The utility model content
The purpose of this utility model is: overcome the weak point of the big displacement of easy generation of existing hand-hydraulic jack existence, design the less hand-hydraulic jack of a kind of displacement, make automobile steady more, safety in the jacking process.
The technical scheme of the utility model technical solution problem is: the less hand-hydraulic jack of a kind of displacement is by base, handle and lifting body are formed, it is at the two ends of the left and right sidesing wall plate that constitutes base adapter shaft and front-wheel and trailing wheel to be set, the parallel track that offers in the centre of described left and right sidesing wall plate with the bottom surface, on the connecting panel of wallboard rear end, be fixedly connected with hydraulic cylinder assembly, on described hydraulic cylinder assembly, be provided with and press hand, be inserted with handle in the middle of pressing hand, piston rod in the described hydraulic cylinder assembly is hinged by bearing pin and the sliding rack that promotion jacking arm assembly slides, the left and right sides at described sliding rack is hinged with left and right sides track adjusting wheel with bearing pin, and be embedded in respectively in the track that is provided with in the middle of the left and right sidesing wall plate, described lifting body comprises hydraulic cylinder assembly, the jacking arm assembly, pallet, long connecting rod and strut bar, the upper end of described jacking arm assembly is provided with pallet by the support with its pivotally attached triangle bodily form, the inferior horn both sides of support are hinged with the upper end of two long connecting rods respectively, and the lower end of long connecting rod is embedded in the track by bearing pin and slides.
The bearing pin at the back side is hinged in the middle of the upper end of described strut bar and the jacking arm assembly, and the lower end of strut bar and the wheel shaft of front-wheel are hinged.
The utility model is owing to be provided with strut bar at the lift arm back side, the arm assembly of jacking simultaneously lower end can be slided in track again, can not only increase the jacking moment of jacking arm relatively, and change to carry a tray on it and roll mark along what camber line rose owing to the jacking arm is subjected to pining down of strut bar, therefore its displacement reduces relatively, so the risk of automobile generation slippage also reduces relatively, the safety when this repairs automobile to improving is of great benefit to.
Description of drawings
Fig. 1 is a schematic perspective view of the present utility model;
Each several part title and mark among the figure: 1. pallet, 2. long connecting rod, 3. strut bar, 4. front-wheel, 5. left wallboard, 6. sliding rack, 7. trailing wheel, 8. hydraulic cylinder assembly, 9. press hand, 10. track adjusting wheel, 11. right wallboards, 12. handles, 13. tracks, 14. jacking arm assemblies.
The specific embodiment
As shown in Figure 1: the hand-hydraulic jack that a kind of displacement is less, form by base, handle and lifting body, described base comprises left and right sidesing wall plate 5,12 and front-wheel 4 and trailing wheel 7, connection is set with wheel shaft and front-wheel 4 and trailing wheel 7 respectively at the two ends of described left and right sidesing wall plate 5,12, along the middle parallel track 13 that offers of wallboard with its bottom surface, on the connecting panel of wallboard rear end, be fixed with hydraulic cylinder assembly 8, on hydraulic cylinder assembly 8, be provided with and press hand 9, in the middle of pressing hand 9, be inserted with handle 12.Piston rod in the described hydraulic cylinder assembly 8 is hinged with the sliding rack 6 that promotion jacking arm assembly 14 slides, and is hinged with track adjusting wheel 10 in the left and right sides of described sliding rack 6 with bearing pin, and is embedded in respectively in the track 13 of wallboard.Described lifting body comprises hydraulic cylinder assembly 8, jacking arm assembly 14, pallet 1, long connecting rod 2 and strut bar 3.The upper end of described jacking arm assembly 14 is provided with pallet 1 by the support with its pivotally attached triangle bodily form, and the inferior horn both sides of support are hinged with the upper end of two long connecting rods 2 respectively, and the lower end of long connecting rod 2 is embedded in the track 13 by bearing pin and slides.The bearing pin at the back side is hinged in the middle of the upper end of described strut bar 3 and the jacking arm assembly 14, and the wheel shaft of the lower end of strut bar 3 and front-wheel 4 is hinged.
This hand-hydraulic jack is when work, its front-wheel 4 is inserted between ground and the car body, make pallet 1 be close to a certain position of car body, handle 12 is inserted into presses in the hand 9, slowly pull handle 12, give the hydraulic oil pressurization of oil cylinder assembly 8, the piston rod that promotes in the oil cylinder travels forward, driving sliding rack 6 moves forward, force the pallet 1 of jacking arm assembly 14 upper ends slowly to lift, because jacking arm assembly 14 supported bars 3 pin down, the sliding rack 6 of jacking arm assembly 14 lower ends is stressed, and the track adjusting wheel 10 of its both sides will be along track 13 to front slide, so the pallet 1 of jacking arm assembly 14 upper ends can not only rise along camber line, be pallet 1 with jacking arm assembly 14 with approximately perpendicular track jointly with automobile jack-up, so automobile slippage can not take place.After repairing work finishes, the pressure of hydraulic oil in the hydraulic cylinder assembly 8 is removed, pallet 1 is slowly reduced to original position with jacking arm assembly 14 under the automobile action of gravity, and motor tire contacts with ground, jack can be pulled out withdrawal at this moment.
